                                     PART I

ITEM 1.  BUSINESS

THE COMPANY

         Conceptus,  Inc.  ("Conceptus"  or the "Company")  designs and develops
minimally invasive devices for reproductive medical applications.  The Company's
current focus is on the development of a non-surgical approach to fallopian tube
sterilization,  the most commonly performed  contraceptive  procedure worldwide.
Given the Company's Focus on the development of the STOP  contraception  device,
the Company is not  actively  marketing or  manufacturing  its  infertility  and
therapeutic hysteroscopic products.

         The Company's  commercially available infertility products are designed
to improve  the  accuracy  of  diagnostic  procedures  for  infertility,  and to
increase  the  safety  of  resectoscopic  procedures.  Conceptus  has  developed
proprietary  micro-catheter  and  guidewire  systems  that allow  physicians  to
transcervically  (through the cervix) access and navigate the full length of the
fallopian tubes in a non-surgical  approach.  The Company's catheter systems are
based on technology initially developed by Target Therapeutics, Inc. ("Target"),
and licensed  exclusively to Conceptus in the field of reproductive  physiology.
To date, Conceptus has received five 510(k) clearances to market applications of
its  T-TAC(TM)  (Transcervical  Tubal  Access  Catheter)  systems and two 510(k)
clearances for the Selective  Tubal  Assessment to Refine  Reproductive  Therapy
("STARRT")  falloposcopy  products for  proximal  tubal  occlusion.  The Company
commenced  marketing  of  its  catheter  systems  for  certain  applications  in
September 1995.

         In November 1996, the Company entered into the therapeutic hysteroscopy
market through its acquisition of Microgyn, Inc. ("Microgyn"),  a privately held
medical  device  company.  Microgyn's  technology  was  develped to increase the
safety  and  performance  of  resectoscope  procedures,   including  therapeutic
hysteroscopy  procedures,  which  utilize an  endoscope  to guide the  selective
excision of abnormal uterine tissue. The Company began marketing its ERA(TM) and
FUTURA(TM)  resectoscope  sleeves for  gynecology  and urology  applications  in
September 1997 upon 510(k) clearance.

         In July,  1998 the Company  implemented a

                                       2
<PAGE>

restructuring  plan  when  the  Company  determined  that the  near-term  market
potential of the Company's T-TAC,  STARRT, and Microgyn products did not justify
a  direct,  specialty  salesforce.  This  restructuring  reduced  the  number of
employees by approximately  fifty employees from seventy-two at the beginning of
the year by eliminating  all sales and marketing  personnel,  the  manufacturing
function,  and most administrative  personnel.  As a result of these actions the
Company reduced  operating  losses to $1.3 million in the fourth quarter of 1998
from $4.3 million in the fourth quarter of 1997. The Company is actively engaged
in discussions with potential  marketing and manufacturing  partners in order to
bring the T-TAC, STARRT, and Microgyn products to the gynecology market.

         The Company is currently focused on developing its S/TOP(TM) (Selective
Tubal  Occlusion  Procedure)  system  to  provide  a  non-surgical  approach  to
fallopian tube sterilization, the most common method of contraception worldwide.
The Company estimates that over 13 million female  sterilization  procedures are
performed annually worldwide.  The S/TOP system uses the Company's transcervical
tubal access technology to deliver a proprietary  micro-coil device to the lumen
of the  fallopian  tube.  Conceptus  believes  that the S/TOP  system will allow
physicians to perform fallopian tube  sterilization in an office setting without
general  anesthesia.  The Company also believes that the  elimination of surgery
from the procedure  will increase both patient  demand for the procedure and the
availability  of tubal  sterilization  in developing  countries,  where surgical
facilities  may be  limited.  The United  States  accounts  for less than 20% of
annual  worldwide  fallopian  tube  sterilization  procedures,  and the  Company
estimates that the United States market for such procedures exceeds $1.5 billion
annually.  Conceptus has performed clinical feasibility studies in two different
patient groups and is currently engaged in a Phase II study of effectiveness.

         Conceptus  has an  exclusive,  worldwide,  royalty-free  license to the
reproductive  applications of technology  developed by Target, a manufacturer of
minimally invasive medical devices for neurovascular applications, which in 1997
became a separate business unit of Boston Scientific  Corporation  ("BSC").  BSC
beneficially owns  approximately 15% of the Company's  outstanding Common Stock.
Conceptus  was  formed in 1992 in  response  to  reports  by  physicians  of the
successful use of Target's products to access the fallopian tubes.

         In November  1998,  the Company  announced  that it has  retained  CIBC
Oppenheimer  Corporation  to evaluate  strategic  alternatives  for the Company,
including  inquiries that have been received by the Company  regarding  possible
business  alliances.  The  Company  intends to review  opportunities  in women's
health, its traditional market focus, as well as other areas of medicine.

HUMAN REPRODUCTION

         Human  reproduction  has been the  focus of  increased  scientific  and
medical attention over the last twenty years.  Contemporary  lifestyle  choices,
such as  deferred  childbearing,  have led to an  increased  demand for  certain
reproductive  medical  services,  including  the  treatment of  infertility  and
improved methods of  contraception.  As a result,  increasing  numbers of OB/GYN
specialists in the United States treat infertility as well as other

                                       3
<PAGE>

reproductive disorders,  and the number of family  planning/reproductive  health
units in community hospitals in the United States increased sice 1985.

Contraception Overview

         Despite the risks,  high  costs,  and  recovery  time  associated  with
surgical  sterilization  performed  under general  anesthesia,  surgical  female
sterilization is the most widely used form of contraception in the United States
and  internationally.  According  to a 1995  survey by the  Centers  for Disease
Control and Prevention,  female  sterilization is the most commonly used form of
contraception in the United States by women between the ages of 15 and 44. Among
women 35 years and over,  33% rely on  sterilization  and among all  married  or
divorced   women  over  35  years  of  age,   54%  utilize   sterilization   for
contraception.  The high rate of reliance on female sterilization is due in part
to concerns about the safety and reliability of those birth control methods that
are readily  accepted by younger women.  Consequently,  despite recent favorable
clinical  studies,   patient  concerns  about  the  long-term  effects  of  oral
contraceptives  have limited their acceptance among women 35 and over where only
12% of these women use oral contraceptives.  Use of intrauterine devices ("IUD")
in the United  States has  declined in women of all age groups.  Due to concerns
that use of IUDs may result in increased  incidence of pain and heavy  menstrual
bleeding,  which could mask the symptoms of serious uterine disease, use of IUDs
among women in the United States age 15 - 44 is less than 1%. For these reasons,
women are seeking new methods of permanent contraception. Increasingly, women in
the United States have turned to surgical tubal sterilization,  which has become
the contraceptive  method of choice. In 1995, 59% of women between 15 - 44 years
of age  relied  on tubal  sterilization,  compared  with  only  23% in 1973.  In
developing  countries where there are concerns about population  growth,  23% of
all women have  undergone  surgical tubal  sterilization.  Throughout the world,
there is a need for a safe, non-surgical, and permanent contraceptive method.

         
Because the fallopian tubes are the organs in which conception  occurs,
they serve a critical  function  in the  reproductive  process and are often the
focus of treatment  whether the objective is to increase a woman's  reproductive
potential,  such  as  in  the  treatment  of  infertility,  or to  decrease  her
reproductive potential,  such as in the performance of sterilization procedures.
Surgical  fallopian tube  sterilization has become the fastest growing method of
contraception  worldwide,  especially  among  women  over  35,  because  of  its
reliability,  and the  absence  of  chronic  side  effects  associated  with the
procedure.  Although  mechanical  occlusion of the  fallopian  tubes is a highly
effective means of achieving female  sterilization,  the difficulty in accessing
the  fallopian  tubes  has made it  necessary  to  perform  surgery  in order to
accomplish fallopian tube sterilization.  Typically, fallopian tubes are ligated
by cutting or  cauterizing  the tubes,  or by mechanical  occlusion of the tubal
lumen  using clips or rings in a surgical  procedure  such as a  laparoscopy  or
laparotomy. The requirement of surgery, however, is an obvious limitation of the
procedure.  The risks  associated  with  surgery,  including the risk of general
anesthesia, infection and other complications, combined with concerns about cost
and recovery  time,  make the procedure less than ideal.  Additionally,  in many
developing  countries,  where the need for permanent  contraception is critical,
there is a shortage of community surgical  facilities.  In the United States, it
is  estimated  that  approximately  1.3  million  surgical  tubal  sterilization
procedures are performed  annually.  The average cost of these procedures ranges
from approximately  $2,500 to approximately  $8,000,  depending on the degree of
invasiveness of the surgery.

S/TOP System Procedure-Specific Product

                                       4
<PAGE>

         The Company is developing a proprietary micro-coil sterilization device
which is  deployed  permanently  into each  fallopian  tube using the  Company's
minimally  invasive  tubal access and delivery  system and the Company's  unique
delivery wire. The  micro-coil  device has been designed to effectively  occlude
the lumen of the fallopian  tube and be physically  incorporated  into the tubal
wall to prevent  expulsion.  The Company believes that this device and procedure
should reduce the clinical  risks and costs  associated  with most current tubal
sterilization   procedures   while   delivering  a  reliable,   safe  method  of
sterilization.

Clinical and Regulatory Status

          In 1995,  the Company  completed  in vitro  feasibility  studies and a
successful animal study that  demonstrated  100% pregnancy  prevention in the 20
animals  in which the device  remained  correctly  placed.  In  September  1995,
Conceptus  commenced  a Phase I  clinical  study of the  S/TOP  device  under an
Institutional   Review  Board  ("IRB")  approval  with  a  non-significant  risk
determination.  In April  1996  this  study  was  approved  by the FDA  under an
Investigational  Device Exemption  ("IDE").  The study involved the placement of
the S/TOP device in patients at the time of  hysterectomy in order to assess the
ability to access the fallopian  tube,  properly place the device,  and test the
acute retention of the device.  As of November 1998, 68 women have been enrolled
in this study.  IDE approval has been obtained for an expanded  Phase I clinical
study in 20 patients who are scheduled for a hysterectomy  six to 12 weeks after
hysteroscopic  placement of the S/TOP device. In addition to the initial Phase I
trial  objectives,  this study is designed to evaluate the histology of adjacent
tissue  reaction  and  patient  recovery  from the device  placement  procedure.
Twenty-seven  patients have been  enrolled in this study and have  undergone the
S/TOP device placement procedure without anesthesia.  The results from the first
five patients to undergo histologic evaluation of their fallopian tubes provides
early evidence of a local inflammatory tissue response to the device, as well as
damage  to the  tubal  architecture,  which is  expected  to be  unfavorable  to
conception.  In addition,  a  hysterosalpingography  performed just prior to the
hysterectomy  demonstrated  complete occlusion in all tubes tested to date, with
the  exception of three tubes in which the device did not remain due to improper
placement.

         In 1997, the Company  commenced a Phase II clinical study in Australia.
In 1998, a Phase II study was initiated at two sites in the United  States.  The
Company  also tested  several  different  configurations  of the S/TOP device in
pre-clinical  studies, in an attempt to improve handling  characteristics of the
device  and to  address  issues of device  migration  and  expulsion  which were
observed in the early clinical testing.  As of year-end 1998,  fourteen patients
are relying on the device for contraception and are being followed in the study.
In 67 months of wearing and through 37 months of efficacy testing, there were no
pregnancies  reported. A majority of the implantation  procedures were performed
without general  anesthesia and were tolerated by patients.  The Company expects
to follow this study with an expanded Phase II study,  which will likely involve
50 patients.  Depending on the results of this  expanded  Phase II study and the
Company's  on-going  development  efforts,  the  Company  is in the  process  of
formulating a Phase III study,  which will involve a larger  patient  population
and long-term follow up in support of a Pre-Market Approval ("PMA") application.
There can be no assurance  that the Company will be able to  formulate,  design,
and execute a large Phase III study or that such a study will enable the Company
to obtain a PMA of the S/TOP device.

Infertility and the Role of the Fallopian Tubes in Reproduction

         Infertility  is one of the most  common and  emotionally  traumatic  of
reproductive  disorders and appears to be increasing in most developed countries
due to both sociological and epidemiological factors. Studies indicate that five
to eight  million  couples  in the  United  States  (or up to 15% of  couples of
childbearing age from 20 to 44) are clinically infertile, which has been defined
as the failure to conceive  after one year of unprotected  intercourse.  Current
estimates of the United States market for diagnosis and treatment of infertility
are in excess of $2.0 billion annually.

         Because the fallopian tubes are the organs in which conception  occurs,
they serve a critical role in the reproductive  process.  Of the up to 8 million
couples   experiencing   infertility  in  the  United  States,   fallopian  tube
infertility  may affect as many as 2.8 million.  Yet, the fallopian tubes do not
lend  themselves  to easy  study and  treatment.  Because of the  difficulty  in
accessing the fallopian tubes,  current  non-surgical  techniques for diagnosing
fallopian  tube  diseases and  disorders  often do not  adequately or accurately
delineate  the  nature,  extent and  location  of tubal  pathology.  Therapeutic
choices  for  the  treatment  of  infertility  are  equally  constrained  by the
difficulty in accessing the fallopian tubes, and therefore,  most fallopian tube
therapies must be performed surgically.

         The most  commonly  performed  fallopian  tube  infertility  diagnostic
procedure is  hysterosalpingography  ("HSG"), which involves the injection of an
x-ray  contrast  medium  (or dye)  transcervically  into the uterus to allow the
physician to observe and evaluate  the flow of dye through the  fallopian  tubes
under fluoroscopy (x-ray).  This procedure is often painful and is also known to
be  highly  inaccurate,  with  false-positive  results  in as  many  as  40%  of
HSG-diagnosed  cases of proximal tubal  occlusion  ("PTO").  Because of its high
rate of inaccuracy,  when HSG indicates an occlusion,  the physician will likely
perform   a   surgical    confirmatory    procedure    known   as   laparoscopic
chromopertubation (commonly called "lap and dye").

         Because of the  inability  to access  the  fallopian  tubes  easily and
non-surgically  in order to effect an accurate  diagnosis of tubal health, it is
often difficult for physicians to select the most appropriate therapeutic option
for each patient.  The difficulties in accessing the fallopian tubes also result
in  current  therapies  for  tubal  infertility  being  far more  invasive  than
necessary.

Conceptus' First Platform Technology:  Transcervical Tubal Access Technology

         Conceptus  has developed its  minimally  invasive  transcervical  tubal
access technology to address the clinical problems and technological limitations
presented  by  current  fallopian  tube  infertility  and  tubal   sterilization
approaches.  The Company believes that the ability to directly and nonsurgically
access the fallopian tubes will lead to better reproductive outcomes by:

         o        Improving the accuracy of conventional  diagnostic  procedures
                  performed to assess tubal patency.

         o        Facilitating   the  performance  of  a  new  endoscopic  tubal
                  diagnostic  procedure,  which  will  permit the  diagnosis  of
                  several  key  aspects of tubal  functionality  not  adequately
                  assessed today.

         o        Enabling   physicians   to  select  more   appropriate   tubal
                  therapies, thereby eliminating many unnecessary therapies.

         o        Allowing more tubal  therapies to be performed  nonsurgically,
                  thus avoiding the risks and costs of surgery and the potential
                  for further surgery-induced damage to the fallopian tubes.

         o        Accelerating   the   selection  of   appropriate   infertility
                  treatment,   an  important   consideration   for  women  whose
                  infertility status has already been compromised by age.

         o        Providing   a   non-surgical   approach  to   fallopian   tube
                  sterilization,  thereby  increasing  patient  demand for tubal
                  sterilization  and  expanding its  availability  in developing
                  countries where surgical facilities may be limited.


Infertility Products

         The  Company's   proprietary   transcervical  tubal  access  technology
consists of specially designed,  micro-catheters and guidewires,  designed to be
atraumatic,  which provide non-surgical access through the cervix and uterus and
into the fallopian tubes. These components are combined with the Company's other
procedure-specific   products  to  produce  the  T-TAC  system  and  the  STARRT
Falloposcopy system.

safety  and  performance  of  resectoscope  procedures,   including  therapeutic
hysteroscopy  procedures,  which  utilize an  endoscope  to guide the  selective
excision of abnormal uterine tissue. These procedures,  including endometrial or
fibroid resection and endometrial  ablation,  are growing in clinical acceptance
because they are less invasive,  non-incisional alternatives to the over 600,000
hysterectomies performed in the United States annually.

         In performing uterine therapy using a hysteroscope,  the uterus must be
distended  and the  visibility  maintained  by use of an optically  clear fluid.
Using monopolar (RF) electrosurgical  energy to cut or ablate adds a restriction
on  the  type  of  fluid  that  can  be  used:  a   non-conductive,   hypotonic,
non-physiologic  distention medium must be employed.  Non-conductive  fluids are
electrolyte-free (hypotonic) substances and therefore can change levels of vital
electrolytes such as sodium,  potassium, and chloride in the blood stream of the
patient.  Fluids such as  mannitol,  sorbitol  and glycine are adequate for this
purpose but present a risk to the patient.

                                       8

         In therapeutic hysteroscopy, both small and large blood vessels are cut
as tissue is removed. Since the hypotonic fluids must be infused into the uterus
under pressure as high as 60-80 mmHg in order to distend the uterine  cavity,  a
large  amount  of fluid can be  forced  into  venous  channels,  which  normally
maintain  pressure of about 20 mmHg.  During the procedure,  fluid loss into the
patient is carefully monitored, via fluid deficit calculations, comparing fluids
used versus  fluids  recovered.  The surgeon is kept  apprised of the  patient's
fluid status,  because of the  complications  associated  with the absorption of
large amounts of hypotonic  solutions.  These include  serious heart,  lung, and
brain disorders, which sometimes result in coma or death.

         The Company's ERA product line  consists of the following  products:  a
simple, disposable ERA Resectoscope Sleeve, cutting loops and coagulating roller
balls. The ERA Resectoscope  Sleeve, when installed on a standard  hysteroscope,
changes  the flow of  electrosurgical  energy  delivered  during  cutting.  This
innovative  approach  permits  the use of  isotonic  solutions,  such as  normal
saline,  which are  physiologically  compatible  with the  patient.  The Company
believes  that  the  ability  to  effectively  use  isotonic   solutions  during
hysterscopic   procedures  should  minimize  the  risk  of  serious  electrolyte
disturbances and their associated complications. The ERA product line is easy to
use because it is designed  for total  mechanical  compatibility  with  existing
hysteroscopic instrumentation and power sources.

FUTURA Product Line

         There is also an important urological  application for the resectoscope
sleeve.  The FUTURA  Resectoscope  Sleeve  enables  the  urologist  to perform a
Transurethral  Resection of the Prostate  ("TURP") more safely.  TURP is used to
treat symptomatic  enlargement of the prostate,  or benign prostatic hyperplasia
("BPH").  Approximately  180,000 TURP  procedures  were  performed in the United
States in 1997.

         TURP typically involves the electrosurgical  removal of abnormal tissue
through  a  resectoscope,   without  the  need  for  an  incision.  Conventional
electrosurgical  procedures,  however,  require the use of hypotonic  irrigation
solutions,  the excessive  absorption of which is associated  with a potentially
catastrophic  complication referred to as "TUR Syndrome." In order to reduce the
risk of TUR Syndrome,  most  hospitals have adopted a strict  surgical  protocol
limiting the TURP procedure time,  which may make it difficult for physicians to
completely  resect abnormal  prostate tissue in a single  procedure.  The FUTURA
Resectoscope  Sleeve,  which utilizes the same patented Microgyn technology used
for  the   gynecological   application,   enables  the   urologist   to  perform
transurethral procedures using isotonic (physiologic) solutions, eliminating the
risk of TUR Syndrome, and permitting the extra procedure time that may be needed
to complete resection of the prostate.


Clinical and Regulatory Status

     Both the ERA and FUTURA  Resectoscope  Sleeve  products  have  received FDA
510(k) clearance for therapeutic hysteroscopy.

Research and Development

         The Company's research and development activities are performed through
a  combination  of internal  employees  and  external  consultants.  The Company
intends  to  continue  to focus its  research  and  development  efforts  on the
development  of  the  S/TOP  contraceptive  product.  Research  and  development
expenses in 1998,  1997,  and 1996 were $4.3  million,  $5.4  million,  and $3.8
million, respectively.

Manufacturing

         The Company  eliminated  its  manufacturing  function in July 1998 as a
part of its restructuring.  Prior to eliminating manufacturing,  the Company was
inspected  by  the  FDA,  and  was  in  substantial   compliance  with  all  FDA
requirements  including  FDA Good  Manufacturing  Practices  ("GMP") for medical
devices.  The  Company  has also been  inspected  in the past by the  California
Department  of Health  Services  ("CDHS")  and is  registered  with the State of
California to manufacture its medical devices and drugs. The State of California
Food and Drug Branch  conducted a two-day  inspection of the San Carlos facility
in February 1997 and as a result of that inspection,  recommended that Conceptus
be  issued a drug  license  by the  State of  California  Department  of  Health
Services.  See "Risk  Factors-Dependence  Upon Sole  Source  Suppliers;  Lack of
Contractual  Arrangements"  and - "Limited  Manufacturing  Experience  and Third
Party Manufacturers."

Marketing and Distribution

         Prior to the Company's July 1998  restructuring,  the ERA  resectoscope
sleeve and the STARRT products were marketed by the Company's direct sales force
in the U.S. and Europe.  The T-TAC and FUTURA  products  were  distributed  by a
network of distributors in the U.S., Europe, and Australia. In 1998, the Company
did not have any shipments to its major distribution  partners for the T-TAC and
FUTURA  products.  The  absence  of  shipments  to  these  distributors  and the
elimination  of the  Company's  sales force  resulted in a $977,000  decrease in
sales from 1997. In 1997 and 1996,  sales to major  distributors as a group were
90% and 65% of total sales,  respectively.  Until the Company is  successful  in
establishing  alternate  distribution  and marketing  partners to distribute the
Microgyn,  T-TAC,  and STARRT  products,  revenues are expected to decrease from
1998 to a very low level.  There can be no assurance  that any of the  Company's
existing or future distribution  partners will successfully market the Company's
products  for  applications  in  radiology,  gynecology,  or urology.  See "Risk
Factors-Limited Sales, Marketing and Distribution Experience; Emerging Market."

         In July 1996, the Company  entered into an agreement with  Mallinckrodt
Group, Inc.  ("Mallinckrodt"),  a major supplier of radiological contrast media.
Pursuant to this agreement,  Conceptus granted Mallinckrodt marketing rights for
radiology  applications of the T-TAC system in North, Central and South America.
In June 1996, the Company appointed Schering Health Care, Ltd., a major supplier
of reproductive  pharmaceuticals  to the  interventional  gynecology  market, as
Conceptus'  exclusive  distributor in the United Kingdom. In September 1997, the
Company  entered  into a  marketing  and  distribution  agreement  with  Imagyn,
formerly  UroHealth,  Inc.,  granting Imagyn an exclusive,  worldwide license to
distribute  products for urological  applications  of the  resectoscope  sleeve.
These distribution  agreements are currently dormant. In March 1998, the Company
received notification that Schering Health Care Ltd. terminated the distribution
agreement with the Company, effective May 1999.

         The Company  believes  that  interventional  gynecology  is an emerging
market,  thus there is no proven  distribution  channel  in the  United  States.
Penetrating   this   emerging   market  is  a   challenge   due  to   structural
characteristics  associated with the interventional  gynecology  market.  Unlike
many other physician specialty markets, the interventional  gynecology market is
characterized  by a large number of  office-based  physicians  (7,500) who often
practice  alone or with one other  physician.  Thus,  the number of sales  "call
points"  is large.  In  addition,  interventional  gynecologists  do not tend to
sub-specialize in a particular  procedure within  interventional  gynecology and
thus  perform a large  variety  of  clinical

                                       10
<PAGE>

procedures,  with each  individual  procedure  representing  a relatively  small
amount of the  physician's  total  professional  fees.  Yet, the  interventional
gynecologist   requires   the  same   level  of   in-servicing,   training   and
clinically-based  selling  activities  that  are  required  in  other  physician
specialty markets.  These market  dimensions:  a large,  diffusely-  distributed
custromer  base,  with  no  real   concentration  of  medical  procedures  makes
distribution to the interventional gynecologists a challenge.

         Prior to its July, 1998 restructuring,  Conceptus had sought to license
or acquire products that were  complementary to its products in order to develop
a  "critical  mass" of  medical  devices  to  justify  the  hiring  of a direct,
specialty  sales force.  The Company  believes there are several  companies with
such  products  which  to date  have  been  unable  to  establish  an  effective
distribution  channel for them.  Failing to build a line of products  that would
enable cost effective, direct marketing to the interventional gynecology market,
the Company  eliminated  its sales and  marketing  and  manufacuring  functions,
initiated   discussions  with  potential  marketing  partners  and  focused  its
remaining   internal  resources  on  the  development  of  its  S/TOP  permanent
contraception device. In conjunction with the restructuring, the Company decided
to no longer maintain  compliance with CE Mark  requirements,  which is required
for all products to be sold in the European  Community.  Accordingly,  effective
January 1, 1999, the Company's  current  products cannot be sold directly by the
Company into the European Community.

         The Company generally  operates under written  distribution  agreements
with its  distributors  which grant the  distributor the exclusive right to sell
the Company's  products  within a defined  territory.  These  distributors  also
typically  market other medical  products,  although the Company seeks to obtain
covenants from its distributors  prohibiting them from marketing medical devices
that compete directly with the Company's  products.  The Company's  distributors
typically  purchase  the  Company's  products at a discount  from list price and
resell the products to hospitals, clinics and physicians. Sales to international
distributors  are usually  denominated  in United States  dollars.  The end-user
price is determined by the distributor  and varies from country to country.  See
"Risk Factors Dependence Upon International Distributors and Sales."

Patents, Trade Secrets and Licenses

         The  Company's  policy  is  to  aggressively  protect  its  proprietary
position  by,  among other  things,  filing  United  States and  foreign  patent
applications  to  protect  technology,  inventions  and  improvements  that  are
important to the development of its business.  The Company's  strategy  includes
extending the patent  protection of its in-licensed  technology (from Target) by
filing  procedure-specific  method patents wherever  possible for the use of the
Company's  products  in new  clinical  applications,  as  well  as  aggressively
pursuing patents for all its other inventions and developments.

         As of February 28,  1999,  Conceptus  had applied for 19 United  States
patents,  seven of which  have  been  issued  to the  Company,  and has filed 25
foreign  patents,  two of which have been issued to the Company.  The  Company's
issued  patents  contain  claims  regarding  guidewire  manipulation,   a  novel
guidewire  design and a delivery  mechanism for a tubal  occlusion  device.  The
pending  applications  cover various aspects of the Company's  proprietary tubal
access platform  technology,  including  certain claims specific to falloposcopy
products,  as  well  as  the  Company's  S/TOP  device,  allowing  the  use of a
physiologic  solution during operative  hysteroscopy and other products that are
currently,  or in the  future may be,  used in  conjunction  with the  Company's
product systems.  Conceptus is also the licensee (from Target) for exclusive use
in the field of reproductive physiology,  of substantial technology developed by
Target as described  below,  and has granted to Target an

                                       11
<PAGE>

exclusive  license in certain fields of  interventional  medicine outside of the
field of reproductive  physiology to certain Conceptus  technology.  Conceptus's
exclusive  license  of  Target's  technology  is  applicable  to all  technology
available  to the Company as of February  1, 1996.  Conceptus  does not have any
preferential  rights for Target technology  developed following that date. As of
February 28, 1999, Target held, and Conceptus  exclusively  licensed from Target
within the field of  reproductive  physiology,  78 issued United States patents,
numerous United States patent  applications  and numerous foreign patents issued
and  applications  pending  covering  various  aspects of its  products and core
technology.   Target's   issued   patents  relate  to  the  design  of  Target's
micro-catheters,  the  initial  patent for which  expires in June 2006,  certain
aspects  of   guidewire   design  and  other   important   aspects  of  Target's
micro-catheter,  guidewire and micro-coil  technologies.  In the event that such
Target patents are at any time invalidated,  the Company's  proprietary position
in the marketplace would be severely compromised. In addition, should the Target
technology  licensed to the Company be found to  infringe  upon a third  party's
technology,  the  Company's  sale of products  based on such  infringing  Target
technology could be limited.  Finally,  in the event that the Company materially
breaches  the terms of its license  from  Target,  Target will have the right to
terminate the license.  Any such  termination  of this license would deprive the
Company  of the  right  to  develop  or  sell  products  based  on the  licensed
technology,  which  would  have a  material  adverse  effect  on  the  Company's
business,  financial  condition  and results of  operations.  See "Risk  Factors
Reliance on Patents and Protection of Proprietary Technology."

Government Regulation

United States

         The research,  development,  manufacture,  labeling,  distribution  and
marketing  of the  Company's  products  are subject to  extensive  and  rigorous
regulation by the FDA and, to varying degrees,  by state and foreign  regulatory
agencies.  The Company's  products are regulated in the United States as medical
devices by the FDA under the Federal  Food,  Drug,  and  Cosmetic  Act (the "FDC
Act")  and  most   require   clearance   or   approval   by  the  FDA  prior  to
commercialization.  In addition,  material  changes or  modifications to medical
devices also are subject to regulatory  review and clearance or approval.  Under
the FDC Act, the FDA regulates the research,  clinical  testing,  manufacturing,
safety, labeling, storage, record keeping, advertising,  distribution,  sale and
promotion of medical devices in the United States. The testing for,  preparation
of and  subsequent  review of  applications  by the FDA and  foreign  regulatory
authorities is an expensive,  lengthy and uncertain process.  The failure by the
Company to comply with FDA requirements could result in warning letters,  fines,
injunctions,  civil penalties,  recall or seizure of products,  total or partial
suspension of production,  the government's refusal to grant premarket clearance
or premarket approval for devices, and criminal  prosecution.  Accordingly,  the
Company  has   invested  in  building   an   experienced   team  of   regulatory
professionals.  For  example,  the  Company's  Senior Vice  President,  Clinical
Research,  Regulatory  Affairs and Quality Assurance was appointed by the FDA to
its OB/GYN Advisory Panel.

         The FDA also has the authority to require  clinical  testing of certain
medical  devices.  If clinical testing of a device is required and if the device
presents a  "significant  risk," an IDE  application  must be approved  prior to
commencing  clinical  trials.  The IDE  application  must be  supported by data,
typically  including the results of laboratory  and animal  testing.  If the IDE
application  is  approved  by the FDA,  clinical  trials may begin at a specific
number of investigational  sites with a maximum number of patients,  as approved
by the agency.  Sponsors of clinical  trials are permitted to sell those devices
distributed  in the  course  of the  study  provided  such  costs do not  exceed
recovery of the costs of manufacture,  research,

                                       12
<PAGE>

development  and  handling.  The  clinical  trials must be  conducted  under the
auspices of an IRB pursuant to FDA regulations.

         Generally, before a new device can be introduced into the market in the
United  States,   the   manufacturer  or  distributor   must  obtain   premarket
notification  clearance  under  Section  510(k) of the Federal Food,  Drug,  and
Cosmetic Act ("510(k)") or a premarket approval ("PMA").  In addition,  material
changes to medical  devices  are also  subject  to FDA review and  clearance  or
approval.  If a medical device manufacturer or distributor can establish,  among
other things,  that a device is  "substantially  equivalent" in intended use and
technological characteristics to certain legally marketed devices, for which the
FDA has not required a PMA, the  manufacturer  or distributor may seek clearance
from the FDA to market the device by filing a 510(k).  Though generally believed
to be a shorter,  less costly regulatory path than a PMA, the 510(k) may need to
be supported by appropriate data establishing to the satisfaction of the FDA the
claim of substantial  equivalence to the predicate device. In addition,  the FDA
may require  review by an advisory  panel as a condition for 510(k)  clearances,
which can further lengthen the regulatory  process. In recent years, the FDA has
been requiring a more rigorous demonstration of substantial equivalence.

         Following submission of the 510(k), the manufacturer or distributor may
not place the device into commercial  distribution  unless and until an order is
issued  by the FDA  finding  the  product  to be  substantially  equivalent.  In
response  to a 510(k),  the FDA may  declare  that the  device is  substantially
equivalent to another  legally  marketed device and allow the proposed device to
be  marketed  in the  United  States.  The FDA,  however,  may  require  further
information,   including  clinical  data,  to  make  a  determination  regarding
substantial  equivalence,  or may  determine  that the  proposed  device  is not
substantially  equivalent  and  require  a PMA.  Such a request  for  additional
information or  determination  that the device is not  substantially  equivalent
would delay  market  introduction  of the  products  that are the subject of the
510(k).

         If a manufacturer  or distributor of medical  devices cannot  establish
that a proposed device is substantially equivalent to a legally marketed device,
the  manufacturer  or distributor  must seek premarket  approval of the proposed
device through  submission of a PMA. A PMA must be supported by extensive  data,
including,  laboratory,  preclinical and clinical trial data to prove the safety
and effectiveness of the device as well as extensive manufacturing  information.
Following  receipt  of a PMA,  if the FDA  determines  that the  application  is
sufficiently  complete to permit a substantive  review,  the FDA will "file" the
application.  The PMA approval process can be lengthy,  expensive and uncertain.
FDA review of a PMA  generally  takes  approximately  two years or more from the
date of filing to  complete.  If  granted,  the  approval of the PMA may include
significant  limitations  on the  indicated  uses  for  which a  product  may be
marketed.  The PMA  process  can take  several  years  from  initial  filing and
requires the submission of extensive  supporting data and clinical  information.
There can be no assurance that any future products or applications  developed by
the Company will not require  approval  under the more lengthy and expensive PMA
process. If the Company is required to obtain approval for any products pursuant
to the PMA procedure  or, if the 510(k)  process with respect to any products is
extended for a considerable length of time, the commencement of commercial sales
of the Company's products will be delayed substantially.

         As  of  February  28,  1999,  the  Company  has  received  five  510(k)
clearances  for certain  diagnostic  and  therapeutic  indications  of its T-TAC
system.  In addition,  the Company has received  two 510(k)  clearances  for its
STARRT Falloposcopy system and its Stargate Catheter,  both for the diagnosis of
PTO.  Conceptus has also received two 510(k)

                                       13
<PAGE>

clearances for its FUTURA Sleeve in urology  applications  and its ERA Sleeve in
gynecology applications.

         The  Company  is  also  required  to  register  as  a  medical   device
manufacturer  with the FDA and state agencies,  such as the CDHS and to list its
products with the FDA. As such,  the Company will be  periodically  inspected by
both the FDA and CDHS for compliance with GMP and other applicable  regulations.
These regulations require that the Company manufacture its products and maintain
its  documents in a prescribed  manner.  In July 1994,  the Company's San Carlos
facility  was  inspected by the CDHS with no  observations,  and the Company was
subsequently  granted a California  medical  device  manufacturing  license.  In
February 1997, the Company's San Carlos  facility was inspected by the CDHS, and
granted a California drug manufacturing  license. In March 1997, the Company was
inspected by the FDA, with no action indicated.

         The Company is required to provide  information  to the FDA on death or
serious  injuries that its medical devices have allegedly  caused or contributed
to, as well as product  malfunctions  that would likely cause or  contribute  to
death or serious injury if the malfunction  were to recur. In addition,  the FDA
strictly  prohibits the marketing of approved  devices for uses other than those
specifically  cleared  for  marketing  by the FDA.  If the FDA  believes  that a
company  is not in  compliance  with the law or  regulations,  it can  institute
proceedings  to  detain  or  seize  products,  issue  a  recall,  enjoin  future
violations  and assess civil and  criminal  penalties  against the company,  its
officers and its employees.  Failure to comply with the regulatory  requirements
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

         The promotion of most products  regulated by the FDA is subject to both
FDA and Federal Trade Commission  jurisdictions.  The Company is also subject to
regulation by the  Occupational  Safety and Health  Administration  and by other
government  entities.  Regulations  regarding  the  manufacture  and sale of the
Company's  products  are subject to change.  The  Company  cannot  predict  what
impact, if any, such changes might have on its business,  financial condition or
results of operations. See "Risk Factors Government Regulations."

International

         Export sales of investigational  PMA devices or devices not cleared for
commercial distribution in the United States to certain countries are subject to
FDA export permit  requirements.  In order to obtain such a permit,  the Company
must  provide  the FDA with  documentation  from the medical  device  regulatory
authority  of the country in which the  purchaser  is located,  stating that the
sale of the device is not a violation  of that  country's  medical  device laws.
Recent regulations  eliminate export approval  requirements for  investigational
devices  subject  to an  approved  IDE  which are being  imported  into  certain
countries.

         The European Union has promulgated rules that require  manufacturers of
medical  products to obtain the right to affix to their products the CE Mark, an
international  symbol of adherence to quality assurance standards and compliance
with applicable European Union Medical Device Directives. The ISO 9000 series of
standards for quality  operations  has been  developed to ensure that  companies
know the  standards  of quality to which  they must  adhere to receive  European
Union certification.  ISO 9000 certification is one of the CE mark certification
requirements.  Failure to receive  the right to affix the CE Mark will  prohibit
the Company from selling the product in member  countries of the European  Union
after December 31, 1998. The Company received ISO certification in January 1998,
but since

                                       14
<PAGE>

eliminating  its  manufacturing   function  the  Company  has  allowed  its  ISO
certification to lapse.  Thus the Company is no longer able to affix a "CE Mark"
to its products.

         Many  countries in which the Company  currently  operates or intends to
operate  either  do not  currently  regulate  medical  devices  or have  minimal
registration  requirements;  however, these countries may develop more extensive
regulations in the future which could adversely affect the Company's  ability to
market its products.  In addition,  significant costs and requests by regulators
for additional  information  may be encountered by the Company in its efforts to
obtain  regulatory  approvals.  Any such  events  could  substantially  delay or
preclude  the  Company  from  marketing  its  products  in the United  States or
internationally. See "Risk Factors Government Regulations."

Third-Party Reimbursement

         Market  acceptance of the Company's  products in international  markets
may  be  dependent  in  part  upon  the  availability  of  reimbursement  within
prevailing  healthcare payment systems.  Reimbursement  systems in international
markets vary significantly by country, and by region within some countries,  and
reimbursement  approvals must be obtained on a  country-by-country  basis.  Many
international markets have government-managed health care systems that determine
reimbursement for new devices and procedures. In most markets, there are private
insurance  systems  as  well as  government-managed  systems.  As in the  United
States,  the Company expects that ERA and FUTURA products will be covered within
the  hysteroscopy   procedure   reimbursement   framework.   Large-scale  market
acceptance of the Company's tubal catheterization,  falloposcopy,  sterilization
and other products will depend on the availability and level of reimbursement in
international markets targeted by the Company.  Currently,  the Company has been
informed by its international distributors that the tubal catheterization system
has been approved for  reimbursement  in countries in which the Company  markets
its  products.   The  Company's   falloposcopy  system  has  been  approved  for
reimbursement only in Australia.  Obtaining  reimbursement approvals can require
12 to 18 months or  longer.  There can be no  assurance  that the  Company  will
obtain  reimbursement  in any country within a particular time, for a particular
amount,  or at all.  Failure  to obtain  such  approvals  could  have a material
adverse  effect  on  market   acceptance  of  the  Company's   products  in  the
international markets in which the Company is seeking approvals and could have a
material adverse effect on the Company's sales,  business,  financial  condition
and results of operations.

         Regardless of the type of  reimbursement  system,  the Company believes
that   physician   advocacy  of  its   products   will  be  required  to  obtain
reimbursement.  Availability  of  reimbursement  will  depend  on  the  clinical
efficacy  and cost of the  Company's  systems.  There can be no  assurance  that
reimbursement for the Company's  products will be available in the United States
or in  international  markets under either  government or private  reimbursement
systems,  or that physicians will support and advocate  reimbursement for use of
the Company's  systems for all indications  intended by the Company.  Failure by
physicians,  hospitals  and  other  users of the  Company's  products  to obtain
sufficient   reimbursement  from  health  care  payors  or  adverse  changes  in
government and private  third-party  payors' policies toward  reimbursement  for
procedures employing the Company's products would have a material adverse effect
on the Company's business,  financial  condition and results of operations.  See
"Risk Factors Uncertainty Relating to Third Party Reimbursement."

Competition

         Currently,  fallopian  tubes are ligated by cutting or cauterizing  the
tubes,  or by mechanical  occlusion of the tubal lumen using clips or rings in a
surgical procedure such as a laparoscopy or laparotomy.  The Company is aware of
several   competitors   attempting  to  provide   alternate   methods  of  tubal
sterilization  including  radio  frequency  coagulation,   intratubal  cyrogenic
freezing,   polymeric  embolic  agents,  nitenol  stents,  silicone  plugs,  and
hydrogelic plugs.

         In the infertility  segment,  the Company  believes its primary current
competition  to be existing  methods for  diagnosing  and treating  diseases and
disorders  of the  fallopian  tubes.  Accordingly,  the  Company  competes  with
manufacturers  of products  that are used in other  methods for  diagnosing  and
treating tubal diseases and disorders, such as manufacturers of laparoscopic and
hysteroscopic  devices and other  products that provide more invasive  access to
the fallopian tubes. The Company also competes with certain other companies that
manufacture catheters and guidewires for tubal catheterization and falloposcopic
devices.  Additionally,  certain  smaller  companies are developing  alternative
catheter-based  systems for the diagnosis  and treatment of female  reproductive
disorders which may compete directly with the Company's systems.

         In the therapeutic  hysteroscopy market, there are four major endoscope
companies (Karl Storz Endoscopy,  Inc.,  Olympus,  Inc., Circon  Corporation and
Richard Wolf Medical  Instruments  Corporation) that account for the majority of
sales  of the  equipment  and  instruments  used to  perform  these  procedures.
Although  the  Company  believes  it  has  significant   intellectual   property
protection for its products,  there can be no assurance that these  companies or
others  (e.g.   electrosurgical   generator   manufacturers)  will  not  develop
technology to enable  electrosurgical  therapeutic  hysteroscopy to be performed
with isotonic  solution.  The major  endoscope  companies and others also market
cutting loops and coagulating  roller balls which would be directly  competitive
with those manufactured and marketed by the Company.  There are also a number of
companies  developing  devices to perform  endometrial  ablation using different
energy sources.

         The Company  believes that its products have distinct  advantages  over
those  of  its  competitors   based  on  the  Company's   advanced   proprietary
micro-catheter  and  guidewire  technologies  and its  proprietary  resectoscope
safety  sheath  technology.  However,  many of the  Company's  competitors  have
substantially  greater name recognition and financial resources than the Company
and have greater resources and expertise in research and development,  obtaining
regulatory  approvals,  manufacturing and marketing.  Certain of these companies
are  developing  and  marketing  devices  for the  diagnosis  and  treatment  of
disorders of the female  reproductive system and others may choose to enter this
market  at  a  later  date.  See  "Risk   Factors-Competition;   Uncertainty  of
Technological  Change" and  "-Reliance on Patents and  Protection of Proprietary
Technology."

Product Liability and Insurance

         The manufacture and sale of medical  products  involve an inherent risk
of  exposure  to product  liability  claims and product  recalls.  Although  the
Company has not experienced any product  liability  claims to date, there can be
no  assurance  that  the  Company  will  be able to  avoid  significant  product
liability claims and potential related adverse publicity.  The Company currently
maintains  product  liability  insurance with coverage  limits of $5,000,000 per
occurrence  and an annual  aggregate  maximum of  $5,000,000,  which the Company
believes is  comparable to that  maintained  by other  companies of similar size
serving  similar  markets.  However,  there  can be no  assurance  that  product
liability  claims in connection  with  clinical  trials or sale of the Company's
products  will not exceed such  insurance  coverage 

                                       16
<PAGE>

limits,  which could have a material adverse effect on the Company, or that such
insurance will continue to be available on commercially  reasonable terms, or at
all. In addition,  the Company may require increased product liability  coverage
as more of its products are  commercialized.  Such insurance is expensive and in
the future may not be available  on  acceptable  terms,  if at all. A successful
product  liability  claim or series of claims  brought  against  the  Company in
excess of its insurance coverage,  or a recall of the Company's products,  could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations. See "Risk Factors-Product Liability Risk and Recalls;
Limited Insurance Coverage."

Employees

         As of February 28, 1999 the Company employed 22 individuals, 17 of whom
were engaged directly in research, development, regulatory and quality assurance
affairs.  The Company is dependent  upon several key  management  and  technical
personnel.  The loss of the services of one or more key  employees  could have a
material  adverse  effect on the  Company's  business,  financial  condition and
results of operations.  The Company's success will also depend on its ability to
attract  and  retain  additional  highly  qualified   management  and  technical
personnel.  The Company faces intense competition for qualified personnel,  many
of whom are often subject to competing  employment  offers,  and there can be no
assurance  that the Company  will be able to attract and retain such  personnel.
None of the Company's employees is covered by a collective bargaining agreement.
Conceptus  believes that it maintains good  relations  with its  employees.  See
"Risk Factors-Dependence Upon Key Personnel."

ITEM 2.  PROPERTIES

         The Company is currently occupying  approximately 14,000 square feet in
San Carlos,  California.  The  facility  is subject to a lease which  expires in
December,  1999.  The  Company  has  leased  additional  space in the  amount of
approximately  16,397  square  feet,  also in San  Carlos,  California  which is
subject to a lease which  expires in May,  2002.  The larger  facility  has been
sub-leased at amounts  greater than the Company's lease  obligation  through the
entire  lease  period.  The  Company  believes  that it  will  be able to  lease
additional space or renew its existing leases as necessary.

ITEM 3.  LEGAL PROCEEDINGS

         A complaint  alleging  sexual  harassment was filed against the Company
and certain  named  officers of the Company in the Superior  Court of San Mateo,
California  on December  17,  1997.  As of March 1, 1999,  the Company  does not
believe  that the  outcome  of this  case  will  have a  material  effect on the
operations or financial condition of the Company.  The Company from time to time
is involved in routine legal matters incident to its business.

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

         No matters  were  submitted  to a vote of  stockholders  of the Company
during the fourth quarter of the fiscal year ended December 31, 1998.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

         The  Company's  Common  Stock has been  traded on the  Nasdaq  National
Market under the symbol CPTS since the effective  date of the Company's  initial
public offering on February 1, 1996.  Prior to the initial public  offering,  no
public market  existed for the Common Stock.  The following  table  presents the
high and low closing sale prices for the  Company's  Common Stock as reported in
the Nasdaq National Market for the period indicated.

                                                   High           Low
                                                   ----           ---
     January 1, 1998 through March 31, 1998       $ 5.250        $3.500
     April 1, 1998 through June 30, 1998          $ 3.500        $1.250
     July 1, 1998 through September 30, 1998      $ 1.750        $0.530
     October 1, 1998 through December 31, 1998    $ 2.250        $0.660

     January 1, 1997 thorugh March 31, 1997       $14.250        $9.375
     April 1, 1997 through June 30, 1997          $12.750        $8.500
     July 1, 1997 through September 30, 1997      $10.250        $6.625
     October 1, 1997 through December 31, 1997    $11.000        $4.125

         As of February 28, 1999, the Company had approximately 114 stockholders
of record.  The Company has never paid cash  dividends  on its Common  Stock and
does not anticipate paying cash dividends in the foreseeable future. The Company
intends to retain any future  earnings for  reinvestment  in its  business.  Any
future  determination  to pay cash  dividends  will be at the  discretion of the
Board of Directors and will be dependent upon the Company's financial condition,
results of operations,  capital requirements and such other factors as the Board
of Directors deems relevant.

         In October 1998, the Company  received  notification  from the National
Association of Securities  Dealer's Inc. ("NASD") that due to the decline of the
Company's stock price,  the Company was not in compliance,  throughout the third
quarter of 1998,  with certain  listing  maintenance  requirements of the Nasdaq
National  Market.  In November 1998, the Company's  Common Stock satisfied these
maintenance  requirements  with a closing  bid price of at least $1.00 per share
for ten consecutive  trading days.  While these  maintenance  requirements  were
satisfied within the required  ninety-day period required by the NASD, there can
be no  assurance  that  Company's  Common  Stock  will  stay in  compliance  the
maintenance  requirements.  If delisting were to occur, the Company expects that
trading of its Common Stock would be  conducted on the OTC Bulletin  Board or in
the  over-the-market  in what is commonly referred to as the "pink sheets".  The
closing price of the  Company's  Common Stock on December 31, 1998 was $2.25 per
share.

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

Overview

         Since its  inception  on  September  18,  1992,  the  Company  has been
primarily engaged in the design, development and marketing of minimally invasive
devices for reproductive medical applications. The Company's current focus is on
providing a  non-surgical  approach to fallopian  tube  sterilization,  the most
commonly  performed  contraceptive  procedure  worldwide,  while  continuing  to
support its diagnostic and therapeutic  gynecology  products.  The Company has a
limited history of operations and has experienced  significant  operating losses
since inception. Operating losses are expected to continue for at least the next
several years as the Company continues to expend  substantial  resources to fund
clinical trials in support of regulatory and reimbursement approvals, to conduct
research and development,  and to partner with  appropriate  marketing and sales
partners.

         The  Company's  initial  commercial  products,  the  T-TAC  and  STARRT
Falloposcopy  systems,  have generated  limited sales to date. Prior to the July
1998  restructuring,  the Company had sought to license or acquire products that
were  complementary  to its  products  in order to  develop a  critical  mass of
medical  devices  to  justify  the hiring of a direct,  specialty  sales  force.
Failing to build a line of products  that would  enable cost  effective,  direct
marketing to the interventional  gynecology  market,  the Company  implemented a
restructuring  plan in July 1998 when the Company  assessed  that the  near-term
market  potential  of  these  products  did  not  justify  a  direct,  specialty
salesforce.  This restructuring reduced the number of employees by approximately
fifty from seventy-two at the beginning of the year by eliminating all sales and
marketing  personnel,   the  manufacturing  function,  and  most  administrative
personnel.  As a result of these  actions the  Company  reduced  fourth  quarter
operating losses to $1.3 million in the fourth quarter of 1998 from $4.3 million
in the fourth quarter of 1997.

         In conjunction with the restructuring, the Company decided to no longer
maintain  compliance  with CE  Mark  requirements,  which  is  required  for all
products to be sold in the European  Union.  Accordingly,  effective  January 1,
1999, the Company's current products cannot be sold directly by the Company into
the  European  Union.  The  Company  is  actively  engaged in  discussions  with
potential  marketing  and  manufacturing  partners  in order to bring the T-TAC,
STARRT, and Microgyn products to the gynecology market. The failure to establish
and maintain effective distribution  partnerships and channels for the Company's
products  resulted in a  significant  decrease  in  revenues in 1998.  Until the
Company is successful in establishing marketing and sales partners to distribute
the Microgyn, STARRT, and T-TAC products, revenues are expected to decrease from
1998 to a very low level.

         Prior  to  the   restructuring   the  Company   sold  its  products  to
international  markets  through a limited number of  distributors  who resell to
physicians and hospitals.  Sales to  distributors  are made on open credit terms
and may  include  purchase  discounts.  General  marketing  of the T-TAC  system
commenced upon the receipt of a 510(k) clearance for diagnosis of proximal tubal
occlusion in August 1995.  Sales in 1996 were through a small direct sales force
and two significant distributors on open credit terms and consisted primarily of
commercial  shipments of T-TAC  products.  Sales in 1997 and 1998 were through a
small direct sales force (which was eliminated in July, 1998) and  distributors,
on open credit terms and consisted of commercial shipments of T-TAC, STARRT, ERA
and FUTURA products.

                                       21

         In the fourth  quarter of 1996 the Company  presented  results from the
IMSF study of its STARRT Falloposcopy  system. Study data showed that use of the
STARRT  Falloposcopy  system  altered  infertility  diagnosis in the majority of
cases versus conventional  infertility diagnosis.  In February 1998, the Company
received 510(k) clearance of its second generation STARRT catheter, the Stargate
Catheter,  a component of the  Company's  STARRT  Falloposcopy  System,  for the
diagnosis of PTO. The Stargate Catheter is a modification of the VS Falloposcopy
Catheter, which was previously cleared for marketing in the United States by the
FDA. The Stargate Catheter is designed to improve visualization of the fallopian
tube by maintaining  sufficient space between the wall of the fallopian tube and
a micro endoscope. Limited marketing of the STARRT product line occurred in 1998
to three  customers  in the  United  States and in  Europe,  one large  customer
purchased a moderate  evaluation  quantity  of this new  Stargate  catheter  and
related products.

         On  November  26,  1996,  the  Company  completed  the  acquisition  of
Microgyn,  a privately held medical device company developing  products designed
to improve the safety and  performance  of  resectoscope  procedures,  including
therapeutic  hysteroscopy.  The Company  acquired all of the outstanding  common
stock of Microgyn,  Inc. in exchange for $3.0 million in cash on the acquisition
date and $1.0  million in the form of 104,708  shares of common stock issued six
months after the  acquisition  date,  plus $752,000 due to assumption of certain
liabilities and related acquisition expenses.  The acquisition was accounted for
using the  purchase  method  and $4.8  million  was  written-off  as  in-process
research and development in 1996.  Future earn-out  payments in the form of cash
or stock, at the option of Conceptus,  is payable to the former  shareholders of
Microgyn based upon meeting  certain future  milestones.  The Company  completed
product development of the Microgyn product portfolio in 1998.

         In the second  half of 1997 the  Company  began  marketing  the ERA and
FUTURA  Resectoscope  Sleeve  products from the Microgyn  technology  portfolio.
These  products  allow  the  use  of   physiologic   solution  when   performing
hysteroscopic procedures,  which increases the safety of resection procedures by
eliminating the risk of dilutional hyponatremia, a complication that can lead to
serious heart, lung, and brain disorders.  The Company received 510(k) clearance
for its FUTURA Resectoscope Sleeve for urology applications in the first quarter
of 1997. In September 1997, the Company  received  510(k)  clearance for its ERA
Resectoscope  Sleeve for gynecological  procedures.  Also in September 1997, the
Company  entered  into a  marketing  and  distribution  agreement  with  Imagyn,
formerly  UroHealth,  Inc.,  granting Imagyn an exclusive,  worldwide license to
distribute  products for urological  applications  of the  resectoscope  sleeve.
Since December 31, 1997, Imagyn has not purchased any of the Company's products.
In March  1998,  Imagyn  notified  the  Company of its intent to  terminate  the
distribution  agreement  between the parties as of June 30,  1998.  Although the
Company and Imagyn are currently  renegotiating the terms of their relationship,
there can be no  assurance  that the  parties  will reach an  agreement  on such
terms.  There  can be no  assurance  that the  Company  will be able to obtain a
suitable  alternate  distributor  for its products for urological  applications.
Unit sales of the Microgyn sleeve products in 1998 were significantly  below the
levels required to meet agreed upon milestones.  The Company is actively seeking
sales and  marketing  partners to  distribute  the ERA  Resectoscope  Sleeve for
gynecologic applications in the United States and internationally.

         Certain  of  the  Company's  products  were  manufactured  by  original
equipment  manufacturers  while  others were  manufactured  by  Conceptus at its
location in San Carlos,  California.  In the fourth quarter of 1997, the Company
acquired the exclusive  manufacturing rights from Medical Scientific,  Inc., the
supplier of the Company's ERA and FUTURA Resectoscope Sleeves. The manufacturing
know-how related to the ERA and FUTURA Resectoscope Sleeves has been transferred
to the Company's  facility in San Carlos.

                                       22
<PAGE>

If  the  volume  of  T-TAC,   STARRT,   ERA,  and  FUTURA   products   increases
significantly,  as a result of securing marketing partners,  the Company expects
to contract with original  equipment  manufacturers in order to maintain product
supply.

         Future  revenues and results of operations may fluctuate  significantly
from quarter to quarter and will depend upon,  among other factors,  the rate at
which  the  Company  establishes  domestic  and  international  distributors  or
marketing  partners,  actions relating to regulatory and reimbursement  matters,
the extent to which the Company's  products gain market  acceptance,  the timing
and size of  distributor  purchases,  the progress of clinical  trials,  and the
introduction  of competitive  products for diagnosis and treatment of the female
reproductive system. The Company believes that development of the T-TAC, STARRT,
and ERA and FUTURA  products has reached a logical  stage  sufficient  to enable
distribution  to the  marketplace.  Therefore,  the  Company  does not expect to
expend significant  resources on further  development of these products nor does
the Company plan on expending  significant  resources  marketing  these products
without a significant  marketing and distribution  partner.  Future sales of the
T-TAC,  STARRT, ERA, and FUTURA products are expected to be very low or decrease
from current levels until effective distribution partners are secured.

         The  Company  continues  to  devote  significant  financial  and  human
resources on the development of the S/TOP device, a non-surgical  alternative to
surgical tubal  ligation,  the most commonly used method of  sterilization.  The
system utilizes a unique  micro-coil  designed to be permanently  implanted into
the  fallopian  tube in order to obtain  effective  sterilization.  Hysterectomy
patients have  participated  in trials to determine  the tissue  response to the
implanted  microcoil.  In July 1997,  the Company  commenced a Phase II efficacy
study of the S/TOP  system in  Australia.  The  Phase II study  involves  device
placement in fertile women who desire  permanent  sterilization.  Study patients
will be monitored for a minimum of two years. In 1998, the Phase II was expanded
to include an additional  site in Australia and two sites in the United  States.
In  response  to early  Phase II results in which  S/TOP  device  expulsion  and
migration were noted,  device and procedural  modifications  were implemented in
mid-1998.  Since that time,  there have been no reported  device  expulsions  or
migrations.  The Company has also been conducting a proof-of-principal  study in
which patients  scheduled for a  hysterectomy  in six to twelve weeks consent to
have S/TOP  devices  implanted and removed at  hysterectomy,  in order to enable
hystological  evaluation of the devices  in-situ in the fallopian  tube. In this
study,  an  independent  laboratory  has  reported  findings of an acute  tissue
response at the site of S/TOP device  implantation,  tissue  in-growth  into the
S/TOP  device and a tubal  environment  that is  "hostile  to  conception".  The
Company  believes  that these are  important  components  of the S/TOP  device's
method of action of  contraception.  As of December 31, 1998,  fourteen patients
with proven fertility,  have been relying on the device for contraception and no
pregnancies have been reported.  Based on theses  preliminary  findings from the
Phase II trial,  the Company is in the process of developing plans to expand the
clinical  testing  of the S/TOP  device  into a Phase III  clinical  trial.  The
Company is seeking a significant  clinical partner to assist in the planning and
execution  of a large  clinical  trial of the S/TOP device and plans to actively
seek and secure such a partner.  There can be no  assurance  that the  Company's
efforts to find an appropriate clinical partner will be successful.

         In  November  1998,  the  Company   announced  that  it  retained  CIBC
Oppenheimer  Corporation  to evaluate  strategic  alternatives  for the Company,
including  inquiries that have been received by the Company  regarding  possible
business  alliances.  The  Company  intends to review  opportunities  in women's
health, its traditional market focus, as well as other areas of medicine.

         In October 1998, the Company  received  notification  from the National
Association of Securities  Dealer's Inc. ("NASD") that due to the decline of the
Company's stock price,  the

                                       23
<PAGE>

Company  was not in  compliance,  throughout  the third  quarter  of 1998,  with
certain  listing  maintenance  requirements of the Nasdaq  National  Market.  In
November  1998,  the  Company's   Common  Stock  satisfied   these   maintenance
requirements  with a  closing  bid  price of at least  $1.00  per  share for ten
consecutive  trading days. While these  maintenance  requirements were satisfied
within the  required  ninety-day  period  required by the NASD,  there can be no
assurance  that Company's  Common Stock will stay in compliance the  maintenance
requirements.  If delisting were to occur,  the Company  expects that trading of
its  Common  Stock  would  be  conducted  on the OTC  Bulletin  Board  or in the
over-the-market in what is commonly referred to as the "pink sheets".

Results of Operations

Years Ended December 31, 1998, 1997 and 1996

         Sales  decreased  by $1.0  million  in 1998 to $0.4  million  from $1.4
million in 1997 as a result of the lack of orders from significant  distribution
partners combined with the elimination, in July 1998, of all sales and marketing
personnel.  Sales  increased  115% to $1.4  million in 1997 from $0.7 million in
1996. This increase was due to increased  commercial  shipments of the Company's
T-TAC  products to a  significant  domestic  distributor,  as well as commercial
shipments of the Company's FUTURA products to a new domestic distributor.  Sales
to domestic customers  represented 33%, 83%, and 68% of sales in 1998, 1997, and
1996,  respectively.  The  decrease  in  domestic  sales  in  1998 is due to the
elimination of all sales and marketing personnel in July 1998.


         Cost of sales  decreased $1.8 million in 1998 to $1.7 million from $3.5
million in 1997 due to the  absence of  approximately  $1.1  million of expenses
incurred  in 1997 for the  purchase  of  manufacturing  rights for the  Microgyn
sleeve products combined with the elimination of all manufacturing activities in
July  1998.  Cost of sales  increased  191% to $3.5  million  in 1997  from $1.2
million in 1996. This increase was primarily due to  approximately  $1.1 million
associated with the purchase of exclusive  manufacturing rights of the Company's
ERA and FUTURA  products from MSI,  combined with  increased  unit  shipments of
T-TAC and FUTURA products.

         Research and development  ("R&D") expenses,  which include clinical and
regulatory  expenses,  decreased  $1.1 million to $4.3 million in 1998 from $5.4
million in 1997 due to significantly reduced development and clinical activities
associated with the Microgyn, T-TAC, and STARRT products. R&D expenses increased
to $5.4  million  in 1997 from $3.8  million  in 1996  (net of $4.8  million  of
acquired in-process  research and development).  The increase of $1.6 million in
1997  was  primarily  attributable  to the  increased  number  of  research  and
development  employees  and related use of  supplies,  prototype  materials  and
inventory,  and increased  expenses  associated with supporting various clinical
trials.

         As  discussed  above,  the Company  expensed  $4.8  million of acquired
in-process  research and  development  in  connection  with the  acquisition  of
Microgyn in 1996.

         Selling,  general and  administrative  ("SG&A")  expenses  decreased by
approximately  $1.0  million to $5.3 million in 1998 due to  elimination  of all
sales and marketing personnel and significant  administrative  personnel in July
1998. SG&A increased to $6.3 million in 1997 from $4.8 million in 1996. The $1.5
million  increase in 1997 was primarily due to the growth in marketing  expenses
associated with promoting the Company's products and growth of United States and
European sales and marketing personnel,  increased administrative costs required
to support expanding  operations and increased  administrative  costs of being a
public company,

                                       24
<PAGE>

         Net interest and  investment  income were $1.3 million and $1.8 million
in 1998 and 1997, respectively.  The decrease was a result of lower average cash
balances due to the utilization of cash for operations.

         As a result of the items  discussed  above,  net loss decreased to $9.7
million in 1998 from $12.1 million in 1997. Net loss was $11.7 million in 1996.

         The Company's  restructuring in July 1998 reduced operating loss in the
fourth quarter of 1998 to $1.3 million from $4.3 million in 1997.

         At December 31, 1998 the Company had net operating  loss  carryforwards
for federal and state income tax  purposes of  approximately  $38.0  million and
$13.5  million,  respectively.  In  addition,  the Company had  research  credit
carryforwards  of  approximately  $600,000  as of  December  31,  1998.  The net
operating  loss and credit  carryforwards  described  above will expire,  if not
utilized, at various dates beginning in the years 2006 through 2013. Utilization
of the net operating  losses and credits may be subject to a substantial  annual
limitation  due to the change of ownership  provisions  of the Internal  Revenue
Code of 1986, as amended.  The annual limitation may result in the expiration of
net operating losses and credits before utilization.  See "Risk  Factors-Limited
Operating History; Anticipated Future Losses."

         Please see footnotes to financial statements.

Liquidity and Capital Resources

         Since inception,  the Company's cash  expenditures  have  significantly
exceeded its sales,  resulting  in an  accumulated  deficit of $45.4  million at
December 31, 1998. At December 31, 1998,  Conceptus had cash,  cash  equivalents
and investments of  approximately  $17.1 million  compared with $27.1 million at
December 31, 1997.  The decrease in 1998 was  primarily due to $8.9 million used
in  operations,  to fund  increasing  levels of research and  development of the
Company's  S/TOP  contraception  product  and  expansion  of the S/TOP  Phase II
clinical trial.

         Capital  expenditures  in 1998 were  $0.9  million  and were  primarily
leasehold improvements and related furniture and fixtures for a new building. As
a result of the Company's restructuring in July 1998, the Company subleased this
new building and related  funiture and  fixtures,  for the entire lease term, at
amounts  greater  than  the  cost of  improvements  and  related  furniture  and
fixtures.  Capital expenditures in 1997 were $1.0 million compared with $375,000
in 1996. This increase was primarily due to the implementation of a new computer
system, the acquisition of machinery and equipment  necessary to manufacture the
ERA and  FUTURA  Resectoscope  Sleeves  and the  leasehold  improvements  on the
Company's  new  facility.  The  Company  plans  to  finance  its  capital  needs
principally from its existing capital  resources,  and to the extent  available,
bank and lease financing.

         Conceptus   believes  that  its  existing  capital  resources  will  be
sufficient to fund its S/TOP research and development  activities  through 1999.
The Company has  determined  that its cash  resources  are greater  than what is
expected  to be used in 1999 for the S/TOP  development  and  clinical  efforts.
However,  the Company's  future liquidity and capital  requirements  will depend
upon numerous factors, including the progress of the Company's clinical research
and product  development  programs,  execution and  implementation of partnering
arrangements,  the  receipt  of and  the  time  required  to  obtain  regulatory
clearances and approvals, and the resources devoted to developing, manufacturing
and  marketing the

                                       25
<PAGE>

Company's products. Accordingly, there can be no assurance that the Company will
not require additional  financing within this time frame and, therefore,  may in
the future seek to raise  additional  funds  through  bank  facilities,  debt or
equity offerings or other sources of capital. Furthermore, any additional equity
financing may be dilutive to stockholders, and debt financing, if available, may
involve  restrictive  covenants.  Additional  funding may not be available  when
needed or on terms  acceptable  to the  Company,  which  would  have a  material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

RISK FACTORS

         In addition to the other  information  in this Form 10-K, the following
factors  should be  considered  carefully  in  evaluating  the  Company  and its
business. This Form 10-K contains forward-looking  statements that involve risks
and  uncertainties.  The Company's  actual results could differ  materially from
those  anticipated  in these  forward-looking  statements as a result of certain
factors, including those set forth below and elsewhere in this Form 10-K.

         Early State of STOP  Development - Uncertainty  of Product  Development
and  Lack of  Long  Term  Follow-Up  Data.  The  Company  has not yet  completed
development of the STOP  contraception  device and expects to increase  research
and development expenditures as the Company implements design changes in pursuit
of a  commercially  viable design.  To obtain  revenues from the STOP device the
Company must successfully develop,  obtain regulatory approval,  manufacture and
market the STOP  device.  The  Company has not yet  completed  Phase II clinical
trials of the STOP device and  anticipates  significantly  more  expenditures to
complete a large Phase III pivotal clinical trial,  prior to  commercialization.
There can be no assurance that the Company's  research and  development  efforts
will be successfully completed. Additionally, until the development and clinical
testing  processes are complete,  there can be no assurance the STOP device will
perform in the manner  anticipated,  or that the results  observed in animal and
human  clinical  trials will be experienced in long-term use. The first Phase II
placement of the device was in July 1997, and as of December 31, 1998 a total of
twenty-three  patients have been implanted with the device, thus the Company has
obtained  limited  clinical  data on the safety  and  efficacy  of the  product.
Because the Company has not yet obtained any  long-term  safety or efficacy data
there can be no assurance that long-term safety and efficacy data when collected
will be consistent  with the results  obtained in early Phase II clinical trials
nor can there be any assurance that the STOP device can be successfully  used by
a  wide  range  of  patients  on a  long-term  basis  as a  safe  and  effective
contraceptive method.

         Uncertainty of Market Acceptance. The Company's products have generated
limited  revenue to date.  There can be no assurance  that any of the  Company's
existing  or  future  products  will  gain  any  significant  degree  of  market
acceptance  among   physicians,   patients  and  healthcare   payors,   even  if
reimbursement and necessary international and United States regulatory approvals
are obtained.  The Company  believes that  recommendations  and  endorsements by
physicians  will be essential for market  acceptance of the Company's  products,
and there can be no assurance that any such recommendations or endorsements will
be obtained.  The Company  believes that  physicians  will not use the Company's
products unless they determine,  based on clinical data and other factors,  that
these systems are an  attractive  alternative  to other means of diagnosing  and
treating diseases and disorders of the female  reproductive  system and that the
products offer clinical  utility in a  cost-effective  manner.  Acceptance among
physicians will also depend upon the Company's  ability to train  interventional
gynecologists  and  other  potential  users  of the  Company's  products  in new

                                       26
<PAGE>

interventional  techniques  and upon the  willingness  of such  persons to learn
these new techniques.  Failure of the Company's products to achieve  significant
market  acceptance  would  have a  material  adverse  effect  on  the  Company's
business, financial condition and results of operations.

         Limited Sales, Marketing and Distribution Experience;  Emerging Market.
The Company has only limited  experience  marketing  and selling its products in
commercial quantities.  Interventional  gynecology is an emerging medical market
with  widely  varying  practice   patterns.   Therefore,   there  is  no  proven
distribution  channel for marketing the Company's current and future products in
the  United  States  or  internationally.  While the  Company  is  committed  to
establishing an effective distribution channel for its products, there can be no
assurance  that the  Company  will be  successful  in doing so.  The  failure to
establish  and maintain an effective  worldwide  distribution  for the Company's
current or future  products,  or to retain  qualified sales personnel to support
commercial sales of the Company's products, would have a material adverse effect
on the Company's business, financial condition and results of operations.

         Dependence  Upon   Transcervical   Tubal  Access  and   Catheterization
Products.  The  Company's  initial  commercial  products,  the T-TAC and  STARRT
Falloposcopy systems, have generated limited sales to date. Current applications
for these  systems  include  accessing,  diagnosing  and  treating  diseases and
disorders of the fallopian tubes. Expanding the number of applications for these
products will require  additional  development  and, in certain cases,  clinical
trials and regulatory approvals.  The Company will experience a material adverse
effect on its business,  financial condition, and results of operations if these
products   are  not   successfully   commercialized   for   existing  or  future
applications.

         Limited Operating History; Anticipated Future Losses. The Company has a
limited  history of  operations.  Since its  inception  in September  1992,  the
Company has been engaged  primarily in research  and  development  of its T-TAC,
STARRT  Falloposcopy  and S/TOP  systems  and,  since  1996,  the ERA and FUTURA
product  lines.  The Company has  generated  only limited  revenues and has only
limited  experience  in  manufacturing,  marketing  or selling  its  products in
commercial quantities.  The Company has experienced significant operating losses
since  inception  and, as of December 31, 1998,  had an  accumulated  deficit of
$45.4 million. The Company expects its operating losses to continue for at least
the next  several  years as it  continues  to expend  substantial  resources  in
funding  clinical trials in support of regulatory and  reimbursement  approvals,
expansion of  manufacturing,  marketing  and sales  activities  and research and
product development or acquisition.  Due to the expense and unpredictable nature
of these activities,  there can be no assurance that the Company will achieve or
sustain profitability in the future. Whether the Company can successfully manage
the transition to a large-scale  commercial enterprise will depend upon a number
of factors, including obtaining selected regulatory and reimbursements approvals
for  its   existing  or  potential   products,   establishing   its   commercial
manufacturing capability, developing its U.S. marketing and selling capabilities
and  establishing an  international  network.  Failure to make such a transition
successfully  would have a material  adverse  effect on the Company's  business,
financial condition and results of operations.

         Reliance on Patents  and  Protection  of  Proprietary  Technology.  The
Company's  ability to  compete  effectively  will  depend  substantially  on its
ability to develop and maintain proprietary aspects of its technology. There can
be no assurance that the Company's seven issued patents, any future patents that
may be issued as a result  of the  Company's  United  States or  foreign  patent
applications,  or the patents under which the Company has license  rights,  will
offer any degree of  protection to the Company's  products  against  competitive
products.  There  can be no  assurance  that any  patents  that may be issued or
licensed to the Company or any of the Company's patent  applications will not be
challenged, invalidated or circumvented in the future. In addition, there can be
no assurance that competitors,  many of whom have substantial resources and have
made substantial investments in competing

                                       27
<PAGE>

technologies,  will not seek to apply for and obtain  patents that will prevent,
limit or interfere with the Company's  ability to make, use or sell its products
either in the United States or in international markets.

         The  medical  device  industry  has  been  characterized  by  extensive
litigation  regarding  patents  and  other  intellectual  property  rights,  and
companies in the industry have employed intellectual property litigation to gain
a competitive advantage.  There can be no assurance that the Company will not in
the future  become  subject to patent  infringement  claims  and  litigation  or
interference  proceedings  declared by the United  States  Patent and  Trademark
Office  ("USPTO")  to  determine  the  priority of  inventions.  The defense and
prosecution of intellectual  property suits, USPTO interference  proceedings and
related legal and administrative proceedings are both costly and time consuming.
Litigation may be necessary to enforce patents issued to the Company, to protect
the  Company's  trade  secrets or know-how or to determine  the  enforceability,
scope and validity of the proprietary rights of others.

         Any litigation or interference  proceedings  involving the Company will
result in substantial expense to the Company and significant diversion of effort
by the Company's technical and management personnel. An adverse determination in
litigation or  interference  proceedings to which the Company may become a party
could subject the Company to significant liabilities to third parties or require
the  Company  to  seek  licenses  from  third  parties.   Although   patent  and
intellectual  property  disputes  in the  medical  device  area have  often been
settled through  licensing or similar  arrangements,  costs associated with such
arrangements   may  be  substantial   and  could  include   ongoing   royalties.
Furthermore,  there  can  be no  assurance  that  necessary  licenses  would  be
available  to  the  Company  on   satisfactory   terms,   if  at  all.   Adverse
determinations in a judicial or  administrative  proceeding or failure to obtain
necessary  licenses could prevent the Company from manufacturing and selling its
products,  which would have a material adverse effect on the Company's business,
financial condition and results of operations.

         A patent  issued to Target  Therapeutics,  a unit of Boston  Scientific
Corporation  ("BSC"),  and subject to  Target's  license to the  Company,  which
contains  claims  relating  to the  design of the  Company's  Variable  Softness
micro-catheters   (the   "Target   patent"),   has  been  the  subject  of  four
reexamination proceedings in the USPTO. Following the completion of the first of
such proceedings, the USPTO issued a reexamination certificate and confirmed the
patentability.  After the USPTO's  review of  petitions  for  second,  third and
fourth  re-examinations,  Target  received  notice  from the  USPTO  that it had
reaffirmed the patentability of the claims of the Target patent. In addition, in
November  1994,  Target filed a lawsuit in United States  District Court against
SciMed  Life  Systems,  Inc.  ("SciMed"),   a  subsidiary  of  BSC,  and  Cordis
Endovascular Systems, Inc. ("Cordis"),  a subsidiary of Johnson & Johnson, Inc.,
alleging  infringement  of a Target  patent  relating to variable  stiffness  in
microcatheters,  and seeking damages and  preliminary  and permanent  injunctive
relief against sales of such companies'  products  believed to be infringing the
Target  patent.  The  defendants  responded by  challenging  the validity of the
Target patent, denying infringement and raising other defenses. In May 1996, the
District  Court  granted  Target's  motion  for an  injunction  prohibiting  the
defendants from continuing to sell the products  alleged to infringe the patent.
In July 1996, the United States Court of Appeals for the Federal  Circuit stayed
the  injunction  pending an appeal by the  defendants.  Upon the merger  between
Target by BSC, the lawsuit has been  dismissed as to SciMed.  Subsequently,  the
Court of Appeals vacated the preliminary injuction. The lawsuit was dismissed as
to Cordis  pursuant  to a  settlement  agreement  signed in  January  1998.  Any
invalidation  of the Target patent could have a material  adverse  effect on the
Company's business, financial condition and results of operations.

                                       28

         Legislation  is pending in  Congress  that,  if enacted in its  present
form,  would limit the ability of medical device  manufacturers in the future to
obtain patents on surgical and medical  procedures that are not performed by, or
as a part of, devices or compositions that are themselves patentable.  While the
Company cannot predict  whether the  legislation  will be enacted,  or precisely
what  limitations  will  result  from  the law if  enacted,  any  limitation  or
reduction in the  patentability  of medical and surgical  methods and procedures
could have a material  adverse  effect on the  Company's  ability to protect its
proprietary methods and procedures.

         In  addition  to  patents,  the  Company  relies on trade  secrets  and
technical  know-how  and  continuing  technological  innovation  to develop  and
maintain its competitive position. The Company typically requires its employees,
consultants and advisors to execute  appropriate  confidentiality and assignment
of  inventions  agreements in connection  with their  employment,  consulting or
advisory relationship with the Company.  These agreements generally provide that
all  confidential  information  developed or made known to the individual by the
Company during the course of the individual's  relationship  with the Company is
to be kept  confidential and not disclosed to third parties,  except in specific
circumstances.  The  agreements  also  generally  provide  that  all  inventions
conceived by the  individual in the course of rendering  services to the Company
shall be the  exclusive  property  of the  Company.  There can be no  assurance,
however,  that these  agreements  will not be breached or that the Company  will
have adequate  remedies for any breach.  Furthermore,  no assurance can be given
that  competitors  will  not  independently  develop  substantially   equivalent
proprietary information and techniques or otherwise gain access to the Company's
proprietary technology, or that Conceptus can meaningfully protect its rights in
unpatented proprietary technology.

         Government  Regulation.  The manufacture  and sale of medical  devices,
including the medical devices used in the Company's STOP,  T-TAC, and STARRT and
Microgyn  resectoscope  sleeves, are subject to extensive regulation by numerous
government  authorities,  both in the United States and internationally.  In the
United  States,  the  principal  regulatory  authorities  are the  Food and Drug
Administration ("FDA") and corresponding state agencies,  such as the California
Department of Health Services ("CDHS"). The process of obtaining and maintaining
required  regulatory  clearances is lengthy,  expensive and  uncertain.  The FDA
requires  companies  that wish to  market a new  medical  device or an  existing
medical  device  for use for a new  indication  to  obtain  either  a  premarket
notification  clearance  under  Section  510(k) of the Federal Food,  Drug,  and
Cosmetic  Act  ("510(k)")  or  a  premarket   approval   ("PMA")  prior  to  the
introduction of such product into the market.  In addition,  material changes to
medical  devices are also subject to FDA review and clearance or approval.  If a
medical device  manufacturer or distributor  can establish,  among other things,
that a device is  "substantially  equivalent" in intended use and  technological
characteristics  to certain legally marketed devices,  for which the FDA has not
required a PMA, the  manufacturer or distributor may seek clearance from the FDA
to market  the  device by filing a 510(k).  Though  generally  believed  to be a
shorter,  less  costly  regulatory  path than a PMA,  the  510(k) may need to be
supported by appropriate  data  establishing to the  satisfaction of the FDA the
claim of substantial  equivalence to the predicate device. In addition,  the FDA
may require  review by an advisory  panel as a condition for 510(k)  clearances,
which can further lengthen the regulatory process.  The PMA approval process can
take several years from initial  filing and requires the submission of extensive
supporting  data and clinical  information.  There can be no assurance  that any
future  products  or  applications  developed  by the  Company  will not require
approval  under the more lengthy and  expensive  PMA process.  If the Company is
required to obtain  approval for any products  pursuant to the PMA procedure or,
if  the  510(k)  process  with  respect  to  any  products  is  extended  for  a
considerable  length  of  time,  the  commencement  of  commercial  sales of the
Company's products will be delayed substantially.

                                       29
<PAGE>

         There  can be no  assurance  that the  Company  will be able to  obtain
necessary 510(k) clearances or PMA or other approvals to market its products for
the  intended  uses on a timely  basis,  if at all,  and delays in receipt of or
failure to receive such clearances or approvals, the loss of previously received
clearances or approvals, or failure to comply with existing or future regulatory
requirements  could have a material  adverse  effect on the Company's  business,
financial condition and results of operations.  Moreover, regulatory clearances,
if granted, may include significant  limitations on the indicated uses for which
a product may be marketed.

         Sales of medical  devices  outside of the United  States are subject to
international  regulatory requirements that vary widely from country to country.
The time  required  to obtain  clearance  required by foreign  countries  may be
longer or shorter than that required for FDA  clearance,  and  requirements  for
licensing may differ significantly from FDA requirements.

         The European Union has promulgated rules which require manufacturers of
medical  products to obtain the right to affix to their products the CE mark, an
international  symbol of adherence to quality assurance standards and compliance
with applicable European Union Medical Device Directives. The ISO 9000 series of
standards for quality  operations  has been  developed to ensure that  companies
know the  standards  of quality to which  they must  adhere to receive  European
Union certification.  ISO 9000 certification is one of the CE mark certification
requirements.  Failure to receive  the right to affix the CE mark will  prohibit
the Company from selling such product in member  countries of the European Union
after 1998. In conjunction  with the Company's  restructuring  in July 1998, the
Company  elected to let its  ISO9000  certification  lapse.  Accordingly,  as of
January 1, 1999, the Company  cannot sell its products  directly in the European
Union.

         Regulatory approvals,  if granted, may include significant  limitations
on the  indicated  uses for which the  Company's  products may be  marketed.  In
addition,  in order for companies to obtain such approvals,  the FDA and certain
foreign  regulatory  authorities  impose numerous  additional  requirements with
which medical device  manufacturers must comply. FDA enforcement policy strictly
prohibits  the promotion of approved  medical  devices for uses other than those
specifically  cleared for  marketing by the FDA. The Company will be required to
adhere to applicable  FDA  regulations  regarding Good  Manufacturing  Practices
("GMP") and similar  regulations  in other  countries,  which  include  testing,
control and documentation  requirements.  Ongoing  compliance with GMP and other
applicable   regulatory   requirements   will  be  monitored   through  periodic
inspections by federal and state  agencies,  including the FDA and the CDHS, and
by comparable  agencies in other  countries.  Failure to comply with  applicable
regulatory  requirements,  could result in, among other things, warning letters,
fines,  injunctions,  civil penalties,  recall or seizure of products,  total or
partial  suspension of production,  refusal of the government to grant premarket
clearance  or  premarket  approval for  devices,  withdrawal  of  approvals  and
criminal  prosecution.  Changes  in  existing  regulations  or  adoption  of new
government regulations or policies could prevent or delay regulatory approval of
the Company's  products.  The Company  cannot  predict the impact,  if any, such
changes  might  have  on  its  business,   financial  condition  or  results  of
operations.

         Uncertainty  Relating  to  Third-Party  Reimbursement.  In  the  United
States,  hospitals,  physicians  and other  healthcare  providers  that purchase
medical  devices  generally rely on third-party  payors,  such as private health
insurance  plans,  to  reimburse  all or part of the  cost  associated  with the
treatment  of  patients.   Although   reimbursement  for   catheterization   and
hysteroscopy procedures has generally been available in the United States, there
can be no assurance that such  reimbursement  will continue to be available.  If
FDA   clearance   or  approval  is  received  for  new   products,   third-party
reimbursement  for these products will be dependent

                                       30
<PAGE>

upon decisions by individual health maintenance organizations,  private insurers
and other payors. However, the Company believes that procedures using its STARRT
Falloposcopy  system may be  reimbursed  in the  United  States  under  existing
procedure codes for diagnosis and  re-establishment  of patency of the fallopian
tubes  and,  if  applicable,  for  related  interpretation  of such  procedures.
However,  there  can be no  assurance  that such  procedure  codes  will  remain
available or that the  reimbursement  under these codes will be adequate.  Given
the efforts to control and decrease health care costs in recent years, there can
be no assurance that any reimbursement  will be sufficient to permit the Company
to  achieve or  maintain  profitability.  The  Company  could also be  adversely
affected  by  changes  in  reimbursement   policies  of  government  or  private
healthcare  payors,  particularly  to the extent  that any such  changes  affect
reimbursement  for  therapeutic  or  diagnostic  catheterization  procedures  or
hysteroscopy  procedures  in which the Company's  products are used.  Failure by
physicians,  hospitals  and  other  users of the  Company's  products  to obtain
sufficient  reimbursement  from  healthcare  payors for  procedures in which the
Company's  products  are used,  or adverse  changes in  government  and  private
third-party  payors' policies toward  reimbursement  for such procedures,  could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

         Market  acceptance of the Company's  products in international  markets
may  be  dependent  in  part  upon  the  availability  of  reimbursement  within
prevailing  healthcare payment systems.  Reimbursement  systems in international
markets vary significantly by country, and include both government-sponsored and
private healthcare insurance.  Obtaining  reimbursement approvals can require 12
to 18 months or longer.  There can be no assurance  that the Company will obtain
reimbursement in any country within a particular time, for a particular  amount,
or at all. Failure to obtain such approvals could have a material adverse effect
on market acceptance of the Company's  products in the international  markets in
which the Company is seeking  approvals and could have a material adverse effect
on the Company's sales, business, financial condition and results of operations.

         Competition;  Uncertainty of Technological  Change.  The medical device
industry is highly  competitive.  The Company expects competition for devices to
diagnose  and treat  female  reproductive  disorders  to  increase.  Many of the
Company's  competitors have substantially greater name recognition and financial
resources than the Company and have greater  resources and expertise in research
and development,  obtaining regulatory  approvals,  manufacturing and marketing.
Certain  of  these  companies  are  developing  and  marketing  devices  for the
diagnosis  and  treatment  of disorders  of the female  reproductive  system and
others may choose to enter this  market at a later date.  Additionally,  certain
smaller  companies are  developing  alternative  catheter-based  systems for the
diagnosis  and  treatment  of female  reproductive  disorders  that may  compete
directly  with  the  Company's  systems.  There  can be no  assurance  that  the
Company's  competitors will not succeed in developing  technologies and products
that are more  effective  or less costly than those  developed by the Company or
that  would  render  the   Company's   products   obsolete  or   noncompetitive.
Additionally, there can be no assurance that the Company will be able to compete
effectively  against such  competitors  based on its  abilities to  manufacture,
market and sell its products.

         As the Company  commercializes  its S/TOP system, it expects to compete
against  other  surgical  procedures  for  permanent  contraception,  mechanical
devices and other  contraceptive  methods.  The Company also competes with other
companies for clinical sites to conduct  trials.  The medical device industry is
characterized by rapid and significant  technological change. The length of time
required for product development and regulatory approval plays an important role
in a company's  competitive position.  Consequently,  the Company's success will
depend in part on its ability to respond  quickly to medical  and  technological
changes through the development and  commercialization of new products.  Product
development  involves a high degree of risk and there can be no  assurance  that
the

                                       31
<PAGE>

Company's   research  and  development   efforts  will  result  in  commercially
successfully  products.  The Company  believes that it competes  favorably  with
respect  to these  factors,  although  there  can be no  assurance  that it will
continue to do so and that  competition  will not have a material adverse effect
on the Company's business, financial condition and results of operations.

         Limited   Manufacturing   Experience   and   Reliance  on  Third  Party
Manufacturers.  The Company has limited experience in manufacturing its products
in  commercial  quantities.   In  restructuring,   the  Company  eliminated  its
manufacturing  function. If the Company is successful in estabilishing alternate
distribution  partners for its products the Company plans to utilize third party
manufacturers to manufacture the products. The Company has identified candidates
that it believes  could  adequately  produce the products  with the  appropriate
quality  and  sufficient  volumes.  However,  third  party  manufacturers  often
encounter  difficulties  in scaling up  production  of new  products,  including
problems involving production yields,  quality control and assurance,  component
supply and shortages of qualified personnel.  There can be no assurance that the
Company  and its third  party  manufacturers  will not  encounter  manufacturing
difficulties,  which  could  have a  material  adverse  effect on the  Company's
business, financial condition and results of operations.

         Dependence   Upon   Sole   Source   Suppliers;   Lack  of   Contractual
Arrangements.  Conceptus  purchases  both raw materials used in its products and
finished  goods from various  suppliers and relies on single sources for most of
these items.  The Company does not have formal supply contracts with several key
vendors and, accordingly, no assurance can be made that such firms will continue
to supply the Company with such raw  materials or finished  goods in  sufficient
quantities,  or at all.  Delays  associated  with any  future raw  materials  or
finished goods shortages  could have a material  adverse effect on the Company's
business,  financial  condition and results of operations,  particularly  as the
Company  scales up its  manufacturing  activities  in support  of  international
commercial  sales and, to the extent that FDA  approvals  are  received,  United
States commercial sales.
         Possible  Future  Capital  Requirements.  Conceptus  believes  that its
existing  capital  resources will be sufficient to fund its  operations  through
1999.  However,  the Company's  future liquidity and capital  requirements  will
depend upon numerous factors,  including the progress of the Company's  clinical
research and product development programs,  the receipt of and the time required
to obtain  regulatory  clearances  and approvals,  and the resources  devoted to
developing,  manufacturing and marketing the Company's  products.  The Company's
capital  requirements  will also depend on, among other  things,  the  resources
required to expand  manufacturing  capacity and facilities  requirements and the
extent to which the Company's  products  generate market  acceptance and demand.
Accordingly,  there  can be no  assurance  that the  Company  will  not  require
additional  financing within this time frame and,  therefore,  may in the future
seek to raise additional funds through bank facilities, debt or equity offerings
or other sources of capital. Furthermore, any additional equity financing may be
dilutive  to  stockholders,  and  debt  financing,  if  available,  may  involve
restrictive covenants. Additional funding may not be available when needed or on
terms  acceptable to the Company,  which would have a material adverse effect on
the Company's business, financial condition and results of operations.

         Product  Liability Risk and Recalls;  Limited Insurance  Coverage.  The
manufacture and sale of medical products involve an inherent risk of exposure to
product  liability  claims and  product  recalls.  Although  the Company has not
experienced any product liability claims to date, there can be no assurance that
the  Company  will be able to avoid  significant  product  liability  claims and
potential related adverse  publicity.  The Company  currently  maintains product
liability  insurance  with coverage  limits of $5,000,000  per occurrence and an
annual

                                       32
<PAGE>

aggregate  maximum of  $5,000,000,  which the Company  believes is comparable to
that  maintained  by other  companies of similar size serving  similar  markets.
However,  there can be no assurance that product  liability claims in connection
with  clinical  trials or sale of the  Company's  products  will not exceed such
insurance  coverage  limits,  which could have a material  adverse effect on the
Company,  or that such insurance  will continue to be available on  commercially
reasonable  terms,  or at all. In  addition,  the Company may require  increased
product liability coverage as its products are commercialized. Such insurance is
expensive and in the future may not be available on acceptable terms, if at all.
A successful  product  liability  claim or series of claims brought  against the
Company  in  excess of its  insurance  coverage,  or a recall  of the  Company's
products,  could  have a  material  adverse  effect on the  Company's  business,
financial condition and results of operations.

         Dependence  Upon Key Personnel.  The Company is dependent upon a number
of key  management and technical  personnel.  The loss of the services of one or
more key  employees  could  have a  material  adverse  effect  on the  Company's
business,  financial condition and results of operations.  The Company's success
will also  depend  on its  ability  to  attract  and  retain  additional  highly
qualified  management  and  technical  personnel.   The  Company  faces  intense
competition for qualified personnel, many of whom are often subject to competing
employment  offers,  and there can be no assurance that the Company will be able
to attract and retain such  personnel.  Furthermore,  the Company  relies on the
services of several medical and scientific consultants, all of whom are employed
on a full-time  basis by  hospitals or academic or research  institutions.  Such
consultants  are  therefore not available to devote their full time or attention
to the Company's affairs.

         Reliance on Target Therapeutic's  License. As of February 28, 1999, BSC
beneficially  owned  approximately  14.34% of the Company's  outstanding  Common
Stock. Accordingly,  BSC may be able to exercise influence over the business and
financial  affairs of the Company.  In April 1997, BSC completed the acquisition
of  Target,  by  merging  Target as a wholly  owned  subsidiary.  Certain of the
Company's  products  are based  upon  patents  and other  intellectual  property
licensed  from Target,  on an exclusive  basis within the field of  reproductive
physiology.  In the event that such Target patents are at any time  invalidated,
the  Company's  proprietary  position  in  the  marketplace  would  be  severely
compromised and the Company's  competitors could have the ability to incorporate
the  Target  technology  in their  products.  In  addition,  should  the  Target
technology  licensed to the Company be found to  infringe  upon a third  party's
technology,  the  Company's  sale of products  based on such  infringing  Target
technology could be limited.  Finally,  in the event that the Company materially
breaches  the terms of its license  from  Target,  Target will have the right to
terminate the license.  Any such  termination  of this license would deprive the
Company  of the  right  to  develop  or  sell  products  based  on the  licensed
technology,  which  would  have a  material  adverse  effect  on  the  Company's
business, financial condition and results of operations.

         Potential Fluctuations in Future Quarterly Results. Future revenues and
results of operations  may fluctuate  significantly  from quarter to quarter and
will depend  upon,  among other  factors,  actions  relating to  regulatory  and
reimbursement  matters,  the extent to which the Company's  products gain market
acceptance,   progress  of  clinical  trials  and  introduction  of  competitive
products.

         Volatility  of Stock  Price.  The  stock  market  has from time to time
experienced  significant price and volume fluctuations that are unrelated to the
operating performance of particular companies.  The Company's stock price has in
the past  been,  and may in the future be,  subject to  significant  volatility,
particularly  on a quarterly  basis.  Any  shortfall in revenue or earnings from
levels  expected by securities  analysts could have an immediate and significant
adverse  effect on the trading price of the Company's  Common Stock in any given

                                       33
<PAGE>

period.  Additionally,  the  Company  may not learn  of, or be able to  confirm,
revenue or earnings  variations from estimates until late in the fiscal quarter,
which could result in an even more  immediate and adverse  effect on the trading
price of the Company's  Common Stock.  Finally,  the Company  participates  in a
highly  dynamic  industry,  which  often  results  in  significant  stock  price
volatility. In October 1998, the Company received notification from the National
Association of Securities  Dealer's Inc. ("NASD") that due to the decline of the
Company's stock price,  the Company was not in compliance,  throughout the third
quarter of 1998,  with certain  listing  maintenance  requirements of the Nasdaq
National  Market.  In November 1998, the Company's  Common Stock satisfied these
maintenance  requirements  with a closing  bid price of at least $1.00 per share
for ten consecutive  trading days.  While these  maintenance  requirements  were
satisfied within the required  ninety-day period required by the NASD, there can
be no  assurance  that  Company's  Common  Stock  will  stay in  compliance  the
maintenance  requirements.  If delisting were to occur, the Company expects that
trading of its Common Stock would be  conducted on the OTC Bulletin  Board or in
the over-the-market in what is commonly referred to as the "pink sheets".

         In addition,  the market  prices of the common  stock of many  publicly
held medical  device  companies  have in the past been, and can in the future be
expected  to be,  especially  volatile.  Factors  such  as  fluctuations  in the
Company's operating results,  announcements of technological  innovations or new
products by the Company or its  competitors,  FDA and  international  regulatory
actions,  changes in reimbursement levels,  developments with respect to patents
or proprietary rights,  public concern as to the safety of products developed by
the Company or others,  changes in  healthcare  policy in the United  States and
internationally,  changes in stock market analyst recommendations  regarding the
Company,  its competitors or the medical device industry generally,  and changes
in general market  conditions may have a significant  impact on the market price
of the Company's Common Stock.

         Effect of Certain  Charter  and Bylaw  Provisions;  Shareholder  Rights
Plan.  Certain  provisions of the Company's  Certificate  of  Incorporation  and
Bylaws  may have the  effect of making it more  difficult  for a third  party to
acquire, or of discouraging a third party from attempting to acquire, control of
the Company.  Such provisions could limit the price that certain investors might
be  willing  to pay in the future  for  shares of the  Company's  Common  Stock.
Certain of these  provisions  allow the Company to issue Preferred Stock without
any vote or further action by the  stockholders,  provide for a classified board
of directors,  eliminate  the right of  stockholders  to act by written  consent
without a meeting and eliminate  cumulative voting in the election of directors.
In addition,  the Company has adopted a stockholder rights plan. The stockholder
rights plan, and the charter and bylaw  provisions  described above, may make it
more difficult for stockholders to take certain corporate actions and could have
the effect of delaying or preventing a change in control of the Company.

         Absence of Dividends.  The Company has never paid cash dividends on its
Common Stock and does not anticipate  paying cash  dividends in the  foreseeable
future.  The Company intends to retain any future  earnings for  reinvestment in
its business.  Any future  determination  to pay cash  dividends  will be at the
discretion  of the Board of Directors  and will be dependent  upon the Company's
financial condition, results of operations,  capital requirements and such other
factors as the Board of Directors deems relevant.

         Year 2000  Compliance.  "Year 2000 issue" arises  because most computer
systems and  programs  were  designed to handle  only a  two-digit  year,  not a
four-digit  year.  These computers may interpret "00" as the year 1900 and could
either  stop  processing   date-related   computations  or  could  process  them
incorrectly.  The Company was informed by appropriate vendors that the Company's
information systems are able to process the year 2000 accurately and the Company
has  completed  testing  of such  systems.  Accordingly,  the

                                       34
<PAGE>

Company  does not  anticipate  any Year  2000  issues  from its own  information
systems,  databases, or programs. The costs associated with this assessment were
not  material.  As a result of the  Company's  restructuring  in July 1998,  the
Company  has  determined  that its  level  of  reliance  on major  distributors,
suppliers,  vendors, and customers has been significantly reduced such that Year
2000  specific  issues faced by these third  parties  should not have a material
effect on the  Company's  operations  or financial  conditions.  With respect to
various  financial  services  institutions that the Company relies on to conduct
its  financial  transactions,  the  Company  has  determined  that all its major
financial   services   institutions  are  actively  engaged  in  bringing  their
information systems into compliance with Year 2000 issues. However, their can be
no  assurance  that such  plans will be able to address  fully,  or at all,  the
impact  of the Year 2000  issue on the  Company,  which  could  have a  material
adverse effect upon the Company's financial condition.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company's cash balances in excess of short-term operating needs are
invested in highly  liquid,  short-term  government  securities and high quality
commercial  paper.  However,  due to the  short-term  and high quality nature of
these instruments,  the Company believes these financial instruments are exposed
to a low level of interest rate risk.

First  Option  on each  monthly  anniversary  of the date of grant of the  First
Option and that each Subsequent Option shall become  exercisable in installments
as to 1/12th of the total number of shares subject to the  Subsequent  Option on
each monthly anniversary of the date of grant of the Subsequent Option beginning

Directors'  Plan have an exercise  price  equal to the fair market  value of the

1.   No stock appreciation  rights were granted to the Named Executive Officers in the last fiscal year. Options generally
     vest at the rate of 1/8th of the shares on the six-month  anniversary of the vesting  commencement date and 1/48th of
     the shares granted on each monthly anniversary of the vesting commencement date thereafter.

2.   The 5% and 10% assumed  annual  rates of  compounded  stock price  appreciation  are mandated by the  Securities  and
     Exchange  Commission.  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 ten year option term will be at the assumed 5% and 10%
     levels or at any other defined level.  Unless the market price of the Common Stock appreciates over the long term, no
     value will be realized from the option  grants made to the  executive  officers.  Potential  Realizable  Value is not
     calculated for options that were canceled during the fiscal year ended December 31, 1998.

3.   The Company granted stock options representing 687,758 shares to employees during the fiscal year.

4.   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.

5.   Mr. Fitch was  terminated  from the  Company in connection with the Company's  restructuring  in July 1998. Mr. Fitch
     continues  to serve as a director of the Company and pursuant to his  severance  agreement  his options  converted to
     non-qualified options and continue to vest under the same terms of the original grant.

6.   Mr.  Messemmer  resigned from the Company  effective May 31, 1998.  Pursuant to the terms of the Company's 1993 Stock
     Option Plan, vested options lapse sixty days from the termination date.

7.   Ms. Schneider was severed from the Company effective  October 31, 1998 as a result of the Company's  restructuring in

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In December  1992,  the  Company  issued to Target  Therapeutics,  Inc.
("Target")  666,666  shares of Series A Preferred  Stock with value of $0.75 per
share along with a warrant to purchase up to 1,000,000 shares of Common Stock at
an exercise price of $1.50 per share,  in exchange for the grant of an exclusive
license to technology  and certain  supply  commitments.  Target  converted this
warrant into 892,857  shares of Common Stock in  connection  with the  Company's
initial public  offering.  Mr.  Randall served as President and Chief  Executive
Officer  of Target  from June 1989 until May 1993 and as  Chairman  of the Board
from April 1993 until May 1994 and served on Target's  Board of Directors  until
April 1997 when Target was acquired by Boston  Scientific  Corporation  ("BSC").
Pursuant to a license  agreement  between  the Company and Target (the  "License
Agreement"), Target granted to the Company an exclusive, worldwide, royalty-free
license, with the right to sublicense, to use any of Target's technology, and to
use, make and sell products incorporating the Target technology, in the field of
reproductive  physiology  (the "Conceptus  field").  The Company granted back to
Target  an  exclusive,  worldwide,  royalty-free  license,  with  the  right  to
sublicense,  to use Conceptus technology (made up of the Company's  improvements
on Target technology and the Company's own developments for use in the Conceptus
field),  and  to  use,  make  and  sell  products  incorporating  the  Conceptus
technology,  in the  fields  of  interventional  neuroradiology,  interventional
radiology,  interventional cardiology and interventional  electrophysiology (but
excluding the Conceptus  field).  These license  grants apply to any  technology
existing on the date of the agreement or subsequently developed through February
1, 1996.  This License  Agreement will terminate upon the later of December 2002
or the  expiration  of all patent rights in the Target  technology.  The License
Agreement also includes  provisions  preventing  Target from engaging in certain
research,  marketing,  sales or  acquisition  activities in the Conceptus  field
during the life of the agreement.  In connection with such  transaction,  Target
and  Conceptus  also  agreed  that  during  the two year  period  following  the
Company's  initial  public  offering  of  securities,  Target  would not acquire
Conceptus  capital  stock to the  extent  that  doing so  would  cause  Target's
ownership  interest  in  the  Company  to  exceed  the  greater  of  20%  of the
outstanding  voting stock prior to such  acquisition or the  percentage  held by
Target  immediately  prior to the  effectiveness of the  registration  statement
covering the Company's initial public offering.

         In March 1994,  Target extended to the Company a $300,000 lease line of
credit for the lease of test,  production  or other  machinery and equipment and
computer hardware,  fixtures and furniture,  on a sale and leaseback basis, with
payment  terms  varying  between  three and four years  depending on the type of
equipment involved.  Conceptus drew down the entire amount of the lease line and
fully  repaid all amounts due as of December 31, 1998.  In  connection  with the
extension  of the lease line,  Target  also loaned to the Company an  additional
$209,000  pursuant to two promissory notes secured by certain tangible  property
of the Company  similar in type to that  subject to the lease line.  These notes
are  payable  over a three to four year period  (depending  on the nature of the
collateral  involved),  and  bear  interest  at the  rate  of  8.5%  per  annum,
compounded  monthly.  As of December 31, 1998 both notes were repaid in full. In
connection with this lease line and secured loan transaction, the Company issued
to Target a warrant to  purchase  up to an  additional  12,000  shares of Common
Stock at an  average  exercise  price of $4.05  per  share,  which  warrant  was
exercised  in  connection  with the  Company's  initial  public  offering  at an
aggregate price of $48,600.

         In March 1994 and May 1995, as part of the  Company's  third and fourth
rounds of financing,  Target purchased an additional aggregate of 101,102 shares
of  Preferred  Stock for a total of  $500,000.  The Company has also  reimbursed
Target for certain employee benefit expenses incurred by Target on the Company's
behalf.  For the year ended December 31, 1996,  approximately  $177,000 was paid
and no  additional  payments  are due to

                                       49
<PAGE>

Target under this  arrangement.  This agreement was discontinued at December 31,
1996.  Upon  the  closing  of  the  Company's  initial  public  offering,   each
outstanding  share of  Preferred  Stock was  converted  into one share of Common
Stock.

         On April 8, 1997, Target completed a merger with BSC, pursuant to which
a wholly  owned  subsidiary  of BSC merged with and into Target (the  "Merger").
Pursuant to the  Agreement  and Plan of Merger  Agreement,  each share of common
stock of Target was  converted  into the right to receive  1.07 shares of common
stock of BSC. As a result of the Merger,  BSC now holds all rights,  preferences
and privileges to the stock,  license fees and technology  agreements which were
previously  held by Target in  connection  with the  Company.  The  Merger was a
tax-free  stock-for-stock exchange for federal income tax purposes and a pooling
of interests for accounting purposes.

         With the approval of a majority of the Board of Directors, on April 24,
1997,  the Company  loaned to Steve  Bacich  $100,000  pursuant to an  unsecured
promissory  note in connection  with his relocation and hiring by the Company as
its Vice  President of Research and  Development.  The note bears  interest at a
rate of 9.5% per annum,  compounded  annually.  In connection with the Company's
retention  agreement  entered  into with Mr.  Bacich in July  1998,  all  unpaid
principal and interest on the loan will be forgiven if Mr. Bacich is employed by
the Company on July 1, 1999.  On March 26, 1998,  the first  anniversary  of the
loan,  $31,206 of the loan balance of $116,667 was  forgiven.  Under the orginal
terms of the loan,  the loan was  previously due in full on the earlier of March
26, 2001 or the  termination of Mr. Bacich's  employment  with the Company.  The
Company has further agreed that if Mr.  Bacich's  employment with the Company is
involuntarily terminated without cause in connection with a change of control of
the Company,  the remaining  balance of the  principal,  plus accrued but unpaid
interest,  shall  be  forgiven  in  full  by the  Company  on the  date  of such
termination. At December 31, 1998, $85,461 was outstanding and payable by Mr.
Bacich.

         Dr. Comite provides  consulting  services to the Company  pursuant to a
consulting  agreement,  dated  September  10, 1997.  The Company paid Dr. Comite
$84,000 in consulting fees for services  rendered during the year ended December
31, 1998.  In July 1998,  7,500 to the fair market  value  ($1.25) of the Common
Stock on July 21, 1998.  These options were repriced when the remaining  term of
the original option was nine years and two months.

         Mr. Palefsky provides  consulting services to the Company pursuant to a
consulting agreement, dated October 15, 1997. During the year ended December 31,
1998, the Company paid Mr. Palefsky $99,993.96 in consulting fees. In July 1998,
90,000  options  granted in September  1997 with an exercise  price of $7.00 per
share were repriced to the fair market value ($1.25) of the Common Stock on July
21, 1998.  These options were  repriced when the remaining  term of the original
option was nine years and two months.

         All future  transactions,  including  any loans from the Company to its
officers, directors, principal stockholders or affiliates, will be approved by a
majority of the Board of Directors,  including a majority of the independent and
disinterested  members  of the Board of  Directors  or, if  required  by law,  a
majority of disinterested  stockholders,  and will be on terms no less favorable
to the Company than could be obtained from unaffiliated third parties.

         The  Company  has  entered  into  indemnification  agreements  with its
officers  and  directors  containing  provisions  which may require the Company,
among other  things,  to indemnify its officers and  directors  against  certain
liabilities  that may arise by reason of their  status or service as officers or
directors (other than liabilities  arising from willful misconduct of a culpable
nature) and to advance  their  expenses  incurred as a result of any  proceeding
against them as to which they could be indemnified.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Conceptus, Inc.

         We  have  audited  the  accompanying  consolidated  balance  sheets  of
Conceptus,  Inc. as of December 31, 1998 and 1997, and the related  consolidated
statements  of  operations,  stockholders'  equity  and cash flows for the three
years in the period ended December 31, 1998. 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  consolidated  financial  position  of
Conceptus,  Inc. at December 31, 1998 and 1997, and the consolidated  results of
its  operations  and its cash  flows for the  three  years in the  period  ended
December 31, 1998 in conformity with generally accepted accounting principles.

                          Notes to Financial Statements
                                December 31, 1998

1. Summary of Significant Accounting Policies

Organization, Ownership and Business

Conceptus,  Inc. ("Conceptus" or the "Company") was incorporated in the State of
Delaware on September 18, 1992 to design,  develop and market minimally invasive
devices for reproductive medical applications. The Company's focus is to provide
a  non-surgical  approach to fallopian  tube  sterilization,  the most  commonly
performed   contraceptive   procedure  worldwide.   The  Company  has  developed
proprietary  micro-catheter  and  guidewire  systems  that allow  physicians  to
transcervically  (through the cervix) access and navigate the full length of the
fallopian tubes in a nonsurgical  approach.  The Company's  catheter systems are
based on technology  initially developed and used by Target  Therapeutics,  Inc.
("Target"),  a  business  unit of Boston  Scientific  Corporation  ("BSC"),  and
licensed exclusively to Conceptus in the field of reproductive physiology.

Consolidation

The consolidated  financial  statements  include the accounts of the Company and
its wholly owned  subsidiary,  Microgyn,  Inc.  ("Microgyn").  All  intercompany
accounts and transactions have been eliminated.

Use of Estimates

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

Revenue Recognition

The Company recognizes  revenue at the time products are shipped.  In 1998, 1997
and 1996, net sales include  direct sales within the United  States,  as well as
through  international  and  domestic  distributors.  These  customers  have  no
contractual right of return or stock rotation privileges.

                    Notes to Financial Statements (continued)
                                December 31, 1998

Net Loss Per Share

Basic and  diluted  net loss per share is computed  using the  weighted  average
number of common shares outstanding. Common equivalent shares from stock options
and warrants are excluded in the net loss per share  calculation  because  their
inclusion would be antidilutive.

Stock-Based Compensation

The  Statement  of  Financial  Accounting  Standards  No. 123,  "Accounting  for
Stock-Based   Compensation"   ("Statement  123"),  provides  an  alternative  to
Accounting  Principles  Board's Opinion No. 25 ("APB 25")  "Accounting for Stock
Issued to  Employees",  in accounting  for  stock-based  compensation  issued to
employees.  The Company  has  elected to  continue  to account  for  stock-based
compensation  using the intrinsic value method  prescribed in APB 25 and related
Interpretations.  Accordingly,  compensation  costs for stock options granted to
employees and directors is measured as the excess,  if any, of the quoted market
price of the  Company's  stock  at the date of the  grant  over  the  amount  an
employee must pay to acquire the stock.

Cash, Cash Equivalents and Investments

The Company considers all highly liquid investments with a maturity from date of
purchase of three months or less to be cash  equivalents.  The Company maintains
deposits with a financial institution in the U.S. and invests its excess cash in
U.S. government obligations and U.S. corporate notes, which bear minimal risk.

Management    considers   all   their    investments   as    available-for-sale.
Available-for-sale  securities  are carried at  estimated  fair value,  with the
unrealized  gains and losses reported in stockholders'  equity.  The fair values
for marketable  debt  securities are based on quoted market prices.  At December
31, 1998 and 1997, the fair value of  investments  approximates  cost.  Realized
gains and losses and  declines  in value  judged to be  other-than-temporary  on
available-for-sale  securities are included in interest and  investment  income.
The cost of  securities  sold is based on the  specific  identification  method.
Interest and  dividends  on  securities  classified  as  available-for-sale  are
included in interest and investment income.

                    Notes to Financial Statements (continued)
                                December 31, 1998

Concentration of Credit Risk

The Company  invests  cash that is not required for  immediate  operating  needs
principally  in a  diversified  portfolio  of  financial  instruments  issued by
institutions  with  strong  credit  ratings.  By  policy,  the  amount of credit
exposure to any one institution,  with the exception of U.S.  government  backed
securities, is limited.

The Company's  revenues to date consist of product  revenues  from  distributors
located in Europe,  Australia and the United States, and direct sales within the
United  States.  The  Company  does not  require  collateral  and  provides  for
estimated credit losses based on a customer credit assessment.  During the years
ended  December  31,  1998,  1997,  and 1996,  the Company  added  approximately
$444,000, $39,000 and $136,000 to its bad debt reserves respectively. During the
same periods,  write-off of uncollectible accounts totaled $18,000,  $4,000, and
$3,000, respectively.

Customers comprising more than 10% of net sales at December 31 are as follows:

                                   Percentage of Net Sales
                 ---------------------------------------------------------------
                       1998                  1997                 1996
                 --------------------- -------------------- --------------------
Customer 1              18%                   --                   --
Customer 2              11%                   --                  11%
Customer 3              --                   63%                  46%
Customer 4              --                   27%                   --
Customer 5              --                    --                  19%

Export  sales were  $147,000,  $239,000  and  $188,000  during  the years  ended
December 31, 1998, 1997 and 1996, respectively.

Inventories

Inventories  are stated at the lower of cost or market.  Cost is based on actual
costs computed on a first-in, first-out basis.

                                December 31, 1998

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation which is
calculated using the straight-line method over the estimated useful lives of the
respective  assets,  generally three to five years.  Leasehold  improvements are
amortized over the lesser of the lease term or the estimated useful lives of the
related assets.

Reporting Comprehensive Income (Loss)

Conceptus  adopted  Statement  of  Financial   Accounting   Standards  No.  130,
"Reporting Comprehensive Income,"("Statement 130) in the year ended December 31,
1998.  Statement  130  establishes  new rules for the  reporting  and display of
comprehensive  income  (loss)  and its  components;  however,  the  adoption  of
Statement 130 had no impact on the Company's net income (loss) or  stockholders'
equity.  Statement  130  requires  unrealized  gains or losses on the  Company's
available for-sale securities,  which prior to adoption were reported separately
in the  stockholders'  equity,  to be  included  in other  comprehensive  income
(loss).

Segment Information

The Company  adopted FAS 131,  "Disclosure  about  Segments of an Enterprise and
Related  Information,"  at December 31,  1998.  FAS 131  establishes  annual and
interim reporting  standards for an enterprise's  operating segments and related
disclosures about its products, services,  geographic areas and major customers.
Under FAS 131, the Company's  operations are treated as one operating segment as
it only  reports  profit and loss  information  on an  aggregate  basis to chief
operating decision makers of the Company.

2. Acquisition

On November 26, 1996,  the Company  completed  the  acquisition  of Microgyn,  a
privately held medical device company  developing  products  designed to improve
the safety and performance of  resectoscope  procedures,  including  therapeutic
hysteroscopy.  The  Company  acquired  all of the  outstanding  common  stock of
Microgyn in exchange for $3.0 million in cash on the  acquisition  date and $1.0
million in cash or stock (at the option of  Conceptus)  payable six months after
the acquisition date, plus $752,000 due to assumption of certain liabilities and
related  acquisition  expenses.  In May 1997,  the  Company  satisfied  the $1.0
million  accrued  acquisition

cost by  issuing  104,708  shares  of the  Company's  Common  Stock.  Additional
contingent  consideration  in cash or  stock,  at the  option of  Conceptus,  is
payable to the former shareholders of Microgyn based upon meeting certain future
milestones. No additional consideration has been paid subsequent to the May 1997
stock issuance.

The acquisition was accounted for using the purchase method.  Under the purchase
method,   the  results  of  operations   of  acquired   companies  are  included
prospectively from the date of acquisition,  and the aggregate  acquisition cost
is allocated to the acquiree's  assets,  liabilities,  and intangibles,  if any,
based upon the fair market  values on the date of  acquisition.  An  independent
valuation, utilizing accepted valuation techniques, was obtained which allocated
the $4,572,000 aggregate acquisition cost as purchase of in-process research and
development.   Consequently,   the   $4,572,000  was  charged  to  research  and
development  expense in the month of  acquisition.  Based on the valuation,  the
Company concluded that technological  feasibility has not been reached and there
was no alternative use of the technology.

The  following  unaudited  pro forma  financial  summary is  presented as if the
operations of the Company and Microgyn were combined as of January 1, 1996.  The
unaudited  pro forma  combined  results are not  necessarily  indicative  of the
actual results that would have occurred had the acquisition  been consummated at
that date, or of the future  operations of the combined  entities.  Nonrecurring
charges,  such as the  write-off  of  approximately  $4.8  million  of  acquired
in-process  research and  development,  are not  reflected in the  following pro
forma financial summary.

Financing Arrangement

In March 1994, the Company entered into an equipment lease line (see Note 6) and
secured loan agreement with Target,  which allows for borrowings of $300,000 and
$209,000, respectively. The borrowings are secured by capital equipment and bear
interest at 8.5% per year.  The notes are payable  over a 36-month  and 48-month
period. As of December 31, 1998 both notes were paid in full. As of December 31,
1997  $40,000 was payable on one note.  In  connection  with these  secured loan
agreements,  Target  was  issued a  warrant  to  purchase  12,000  shares of the
Company's  Common Stock.  The exercise price for 5,000 of these shares was $3.00
per share and the  remaining  7,000  shares had an  exercise  price of $4.80 per
share. As a result of the Company's  initial public  offering,  Target exercised
its warrant at an aggregate price of $48,600.

Operations and Facilities

In  December  1992,  the Company  entered  into a supply  agreement  with Target
whereby  Target agreed to supply to and/or  manufacture  products and components
necessary for the Company to proceed with its research and development  activity
under the license agreement  described above. In 1998, 1997 and 1996, no amounts
were paid to Target under this supply agreement.

In addition,  the Company paid to Target certain employee  benefits  incurred by
Target on the  Company's  behalf.  In 1998 and 1997, no amounts were paid due to
the  discontinuance of the agreement as of December 31, 1996. In 1996,  $177,000
was paid, under this agreement.

Any option holder who elected to reprice an option was not permitted to exercise
the repriced  option,  even if vested,  for one year.  The repriced  options are
reflected as both granted and forfeited options in the 1993 Plan table.

On April 7, 1998,  employee  grants of stock  options  under the 1993 Stock Plan
issued were repriced (a total of 63,300 options) to reflect an exercise price of
$3.50. The repriced options are reflected as both granted and forfeited  options
in the 1993 Plan table.

On August 1, 1996, all  non-officer  employee  grants of stock options under the
1993 Stock Plan issued  between  the date of the public  offering  (February  1,
1996) and June 3, 1996 were  repriced (a total of 93,666  options) to reflect an
exercise price of $10.50. Any option holder who elected to reprice an option was
not permitted to exercise the repriced option,  even if vested, for 90 days. The
repriced options are reflected as both granted and forfeited options in the 1993
Plan table.

1995 Directors Stock Option Plan

On November 29, 1995, the board approved the 1995  Director's  Stock Option Plan
("Directors'  Plan"),  which  allows the  granting  of options for up to 100,000
shares of Common  Stock to outside  directors.  Stock  options may be granted to
outside  directors with exercise  prices of no less than fair market value.  The
options  expire no more than 10 years after the date of grant.  Options  granted
under the  Directors'  Plan will vest over one or three  years.  The options are
only exercisable  while the outside  director  remains a director.  During 1998,
1997 and 1996, 7,500, 32,000 and 12,000 options, respectively, were granted.

1995 Employee Stock Purchase Plan

On November 29, 1995,  the board  approved the 1995 Employee Stock Purchase Plan
("ESPP"),  under which  employees may purchase  shares of the  Company's  Common
Stock, subject to certain  limitations,  at no less than 85% of the lower of the
fair market value at the beginning or end of a six-month purchase period.  Under
the terms of the ESPP, employees can choose each year to have up to 10% of their
annual base  earnings  withheld to purchase the Company's  Common Stock.  During
1998, 1997 and 1996, 29,367 25,285 and 18,524 shares, respectively, were issued.
The Company has reserved  200,000  shares of Common Stock for issuance under the
ESPP.

Pro Forma Valuation of Options

The Company applies APB Opinion No. 25 and related Interpretations in accounting
for its  plans  (see  Note  1).  Accordingly,  no  compensation  cost  has  been
recognized for its fixed stock option plans and its stock purchase plan.

Pro forma  information  regarding net loss and net loss per share is required by
Statement  123 and has been  determined  as if the Company had accounted for its
employee  stock options  granted  subsequent to December 31, 1994 under the fair
value method of Statement  123. The fair value of each option grant is estimated
on the date of grant  using  the  Black-Scholes  option-pricing  model  with the
following weighted-average  assumptions used for option grants in 1998, 1997 and
1996:  dividend  yield of zero,  expected  volatility  factor  of .6,  risk-free
interest rate of 6% and an expected life of 4 years.  In 1997 and 1996, the fair
value  of each  option  grant  is  estimated  on the  date of  grant  using  the
Black-Scholes   option-pricing   model  with  the   following   weighted-average
assumptions used for option grants:  dividend yield of zero, expected volatility
factor of .6,  risk-free  interest  rate of 6% and an expected  life of 5 years.
Compensation  cost is recognized for the fair value of the  employees'  purchase
rights,  which was estimated  using the  Black-Scholes  model with the following
assumptions  for 1998:  dividend  yield of zero, an expected life of four years,
expected  volatility factor of .4 and risk-free interest rate of 6%. In 1997 and
1996,  compensation  cost is  recognized  for the fair  value of the  employees'
purchase  rights,  which was estimated  using the  Black-Scholes  model with the
following  assumptions:  dividend  yield of zero,  an expected life of one year,
expected volatility factor of .4 and risk-free interest rate of 5%. The weighted
average fair values of those purchase rights granted in 1998, 1997 and 1996 were
$0.87,  $3.09 and  $4.32,  respectively.  The  effects of  applying  FAS 123 for
recognizing  compensation  expense and providing pro forma  disclosures in 1998,
1997 and 1996 are not likely to be representative of the effects on reported net
income in future years.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded  options which have no vesting  restrictions  and are fully
transferable.  In addition,  option valuation models require the input of highly
subjective  assumptions  including the expected stock price volatility.  Because
the  Company's  employee  stock  options  have   characteristics   significantly
different from those of traded  options,  and because  changes in the subjective
input assumptions can materially affect the fair value

estimate,  in  management's  opinion,  the existing  model does not  necessarily
provide a  reliable  single  measure  of the fair  value of its  employee  stock
options. For purposes of pro forma disclosures,  the estimated fair value of the
options is amortized to expense over the option's vesting period.  The Company's

8. Income Taxes

As of December 31, 1998,  the Company had net operating loss  carryforwards  for
federal  and  state  income  tax  purposes  of  approximately   $38,000,000  and
$13,500,000,  respectively.  In addition,  at December 31, 1998, the Company had
research credit carryforwards of approximately  $900,000. The net operating loss
and credit carryforwards  described above will expire at various dates beginning
in the  years  2006  through  2013,  if not  utilized.  Utilization  of the  net
operating losses and credits may be subject to a substantial  annual  limitation
due to the ownership change  provisions of the Internal Revenue Code of 1986, as
amended.  The annual  limitation  may result in the  expiration of net operating
losses and credits before utilization.

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

</TABLE>

Because of the Company's lack of earnings history,  the deferred tax assets have
been fully  offset by a  valuation  allowance.  The  increase  in the  valuation
allowance was approximately $5,335,00 during 1997.

9.   Restructuring Accrual

In July 1998, the Company  announced a restructuring  to  significantly  reduced
spending   levels   through  the   elimination   of  all  sales  and  marketing,
manufacturing,  and most  administrative  personnel.  The Company has eliminated
fifty-three positions worldwide since January 1, 1998, through natural attrition
and employee layoffs. At December 31, 1998, $46,000 remains related primarily to
severance  and cobra  payments.  This  restructuring  resulted in an  additional
charge to operating  expense of $920,000  comprised of $725,  000 related to the
reduction in workforce and $195,000 to fully reserve all remaining inventory.

10.  Litigation

The Company is also subject to other legal  proceedings and claims that arise in
the ordinary course of its business.  While  management  currently  believes the
amount of ultimate  liability,  if any,  with respect to these  actions will not
materially affect the financial position, results of operations, or liquidity of
the Company,  the  ultimate  outcome of any  litigation  is  uncertain.  Were an
unfavorable outcome to occur, the impact could be material to the Company.

                                   ENTERPRISES

                              THIRD LEASE ADDENDUM

         This Third Lease Addendum is entered into effective  September 17, 1998
by and  between  Three  Sisters  Ranch  Enterprises,  a  California  partnership
("Landlord") and Conceptus, Inc., a California corporation ("Tenant").

         This Third Lease  Addendum is attached to and forms a part of the Lease
identified  below,  together with any  amendments,  modifications  and exhibits,
including  a  prior  Lease  Addendum  and a prior  Lease  Addendum  and  Partial
Termination   Agreement.   This  Third  Lease  Addendum  constitutes  additional
covenants  and  agreements  which are  intended  to  prevail in the event of any
conflict  between the  covenants  and  agreements  contained in this Third Lease
Addendum  and those  contained  in the Lease  itself  and/or the Lease  Addenda.
Except for the additions,  changes and removals  listed herein,  all other terms
and conditions of the Lease will remain in full force and effect  throughout the
term of the Lease.


                                    Recitals

         A. On or about April 15, 1997, Landlord and Tenant entered into a lease
("Lease"), for the certain premises owned by Landlord, and thereafter executed a
Lease Addendum and a Lease Addendum and Partial  Termination  Agreement.  Tenant
currently occupies 16,397 square feet of 957 Industrial Road, Suites D, F, G, H,
J, L, P and R, San Carlos,  California,  94070 (together, the "Premises"),  that
are all  part of a  building  complex  more  commonly  known  as the San  Carlos
Business Center.

         B. Tenant has  notified  Landlord  that Tenant  intends to sublease the
Premises,  that Tenant  intends to collect rent from the  subtenant in an amount
("Excess Rent") in excess of the Rent due to Landlord under the Lease,  and that
Tenant  intends to enter into a separate  agreement  with the  subtenant for the
leasing of furniture to be used in the Premises.

         C. Tenant has also  notified  Landlord that Tenant has spent the sum of
$575,910 ("Tenant Costs") in tenant improvements for the Premises.


                              TERMS AND CONDITIONS

         1. During the remaining Term of the Lease, for so long as Tenant is not
in material  default  under any of the  provisions  of the Lease (which  default
remains uncured after the expiration of all applicable cure periods),  Paragraph
21B shall be amended to read as follows:

                  B. Bonus Rent. The rent collected by Tenant from the subtenant
                  shall be paid to the parties:

                           1. The  Rent due  under  the  Lease  shall be paid to
                           Landlord.

                           2. That  portion of Excess  Rent up to and  including
                           $0.15 per square foot of the  Premises  shall be paid
                           to Landlord ("Landlord's Share").

                           3.  That  portion  of the  Excess  Rent in  excess of
                           Landlord's Share shall first be allocated and paid to
                           Tenant  to  reimburse  Tenant  for (a) the  costs  of
                           tenant improvements paid for by Tenant, not to exceed
                           $575,910.00  ("Tenant  Costs") and (b) any reasonable
                           brokerage  commission   (`Commission")   incurred  by
                           Tenant in connection with obtaining a sublease.  Such
                           Tenant Costs and  Commission  shall be amortized over
                           the remaining Term of the Lease,  and Tenant shall be
                           paid a monthly  amount  of  Excess  Rent in excess of
                           Landlord's   Share   based   on   such   amortization
                           ("Tenant's Share").

<PAGE>


                           4. Any amount of Excess Rent in excess of  Landlord's
                           Share and  Tenant's  Share  shall be divided and paid
                           ten percent (10%) to Tenant and ninety  percent (90%)
                           to Landlord.

         2. In the event that  Tenant is in  material  default  under any of the
terms of the Lease (which  default  remains  uncured after the expiration of all
applicable  cure  periods),  from and after written  notice from  Landlord,  the
original Paragraph 21B, as set forth in the Lease, shall control the division of
Excess Rent and shall  supercede  and replace the revised  Paragraph  21B as set
forth above in Paragraph 1 of this Third Lease Addendum.

         3. The Option to Renew  provided  for in  paragraph  43 of the Lease is
hereafter  null and void and  neither  Tenant nor the  subtenant  shall have any
option to renew or extend the Term of this Lease.

         IN WITNESS  HEREOF,  the Parties  hereto have executed this Third Lease
Addendum as of the date set forth above.

                  Date")  shall be the earlier of the date on which:  (1) Tenant
                  takes  possession of some or all of the  Premises,  or (2) the
                  improvements  constructed  or to be  construed in the Premises
                  shall have been substantially completed in accordance with the
                  plans and  specifications  described  on Exhibit B, whether or

                  non-compliance by any other tenant or occupant of the Building
                  or Project with any of the above-referenced rules or any other

                  entry, subject to all existing or future applicable municipal,
                  state   and   federal   and   other   governmental   statutes,
                  regulations, laws and ordinances,  including zoning ordinances
                  and regulations  governing and relating to the use,  occupancy
                  and   possession  of  the  Premises  and  the  use,   storage,
                  generation  and disposal of Hazardous  Materials  (hereinafter
                  defined)   in,  on  and  under  the   Premises   (collectively
                  "Regulations").  Subject to the terms and  conditions  of this
                  Agreement,  Tenant,  at is sole expense,  shall use and occupy
                  the Premises in compliance with all laws,  including,  without

                  permits, licenses, covenants and restrictions now or hereafter
                  applicable    to   the    Premises    (collectively,    "Legal
                  Requirements").  The Premises  shall not be used as a place of
                  public accommodation under the Americans With Disabilities Act
                  or  similar  state   statutes  or  local   ordinances  or  any
                  regulations promulgated thereunder, all as may be amended from
                  time  to  time.  Tenant  shall,  at  its  expense,   make  any
                  alterations or modifications,  within or without the Premises,
                  that are  required by Legal  Requirements  related to Tenant's
                  use or  occupation of the  Premises.  Except for  pre-existing
                  obligations  and those  obligations  placed on the Landlord by
                  this Lease Agreement,  Tenant shall, at Tenant's sole expense,
                  strictly comply with all Regulations now in force or which may
                  hereafter be in force  relating to the Premises and the use of
                  the  Premises  and/or  the  use,   storage  or  generation  of
                  Hazardous  Materials  in, on and under  the  Premises.  Tenant
                  shall at its sole cost and expense obtain any and all licenses
                  or permits necessary for Tenant's use of the Premises.  Tenant
                  shall  comply  with  the  requirements  of any  board  of fire
                  underwriters   or  other   similar   body  now  or   hereafter
                  constituted. Tenant shall be solely responsible for compliance
                  with any  requirements  for  modification  to the  Premises to
                  provide for fire  prevention or  suppression  improvements  or
                  modifications,  including  sprinkler  requirements,  as public
                  officials  or law may  require.  Tenant shall not do or permit
                  anything to be done in, on, or about the  Premises or bring or
                  keep  anything  which will in any way increase the rate of any
                  insurance upon the Premises,  Building or Project, or upon any
                  contents  therein,  or cause a cancellation of said insurance.
                  Tenant  shall  indemnify,  defend,  protect and hold  Landlord
                  harmless  from and against any loss,  cost,  expense,  damage,
                  attorneys'  fees or  liability  arising  out of the failure to
                  Tenant to comply  with any  applicable  law or  regulation  or
                  comply with the  requirements as set forth herein.  The taking
                  of  possession of the Premises  shall be  conclusive  evidence
                  that Tenant accepts the Premises and that the Premises were in
                  good condition at the time  possession was taken.  Despite any
                  provision herein to the contrary,  if any asbestos  containing
                  materials  (ACM) is found to exist in the Premises,  which ACM
                  is either (i) friable or  otherwise  dangerous in its existing
                  condition,  or (ii)  necessary  to remove  for the  purpose of
                  completing the tenant  improvement work, then Landlord will be
                  obligated  to  remove  the  ACM  at  its  own  cost,  up  to a
                  cumulative total of $50,000. If the ACM abatement costs exceed
                  $50,000  for  the  total  of all  property  leased  hereunder,
                  Landlord  shall  have the right to  terminate  this lease with
                  respect to any suite where the $50,000 cap would be  exceeded;
                  Tenant shall have the right to any amount in excess of $50,000
                  at its written election within fifteen (15) days of notice; if
                  either  Landlord or Tenant  elect not to proceed  with payment
                  for ACM  abatement  in  excess  of  $50,000  they  shall do so
                  without liability to the other for such election

                  D.  Hazardous  Wastes  Materials.  Excepting  those  chemicals
                  consistent with normal office use ( office cleaning solutions,
                  white out),  Tenant shall not cause,  or allow any of Tenant's
                  Parties  to  cause,  any  Hazardous   Materials  to  be  used,
                  generated, stored or disposed of on or about the Premises, the
                  Building or the  Project.  As used in this  Lease,  "Hazardous
                  Materials"  shall include,  but not be limited to,  "hazardous
                  materials,"  "hazardous  wastes," "toxic substances," or other
                  similar  designations  in any  federal,  state or  local  law,
                  regulation,  or ordinance.  Landlord  shall have the right but
                  not the  obligation  at all  reasonable  times to inspect  the
                  Premises and to conduct tests and  investigations to determine
                  whether Tenant is in compliance with the foregoing provisions,
                  the costs of all such inspections, tests and investigations to
                  be borne by Tenant.  Tenant shall indemnify,  defend,  protect
                  and hold Landlord  harmless from and against all  liabilities,
                  losses, costs and expenses,  demands, causes of action, claims
                  or judgments  directly or  indirectly  arising out of the use,
                  generation,  storage or disposal  of  Hazardous  Materials  by
                  Tenant  or any of  Tenant's  Parties,  which  indemnity  shall
                  include,  without  limitation,  the  cost of any  required  or
                  necessary   repair,   cleanup  or   detoxification,   and  the
                  preparation  of any closure or other required  plans,  whether
                  such action is required or necessary prior to or following the
                  termination  of this Lease.  Neither  the  written  consent by
                  Landlord  to the  use,  generation,  storage  or  disposal  of
                  Hazardous  Materials  nor the strict compliance by Tenant with
                  all laws pertaining to Hazardous Materials shall excuse Tenant
                  from Tenant's  obligation of indemnification  pursuant to this
                  Lease.   Tenant's   obligations   pursuant  to  the  foregoing
                  indemnity shall survive the termination of this Lease.  Tenant
                  shall not be held liable in any manner for the presence of any
                  Hazardous   Materials  existing  on  or  about  the  Premises,
                  Buildings or the Project prior to the first  Commencement Date
                  of the Lease.

REGULATIONS       regulations  Landlord  may  from  time  to time  prescribe  in

                  Premises or Project.  Tenant shall cause  Tenant's  Parties to
                  comply with such rules and regulations.  Landlord shall not be
                  responsible  to  Tenant  for the  non-compliance  by any other
                  tenant or occupant of the  Building or Project with any of the
                  rules and regulations.

                 certified  public  accountants.  Legal and accounting  expenses
                 shall  be  reasonable and shall  not  include  the  cost of any
                 enforcement or eviction  action  against  another tenant at the
                 Project.

                 In the event that the Building is not fully occupied during any
                 fiscal year of the as  determined  by Landlord,  an  adjustment
                 shall be made in computing  the Basic  Operating  Cost for such
                 year so that Tenant pays an  equitable  portion of all variable
                 items of Basic  Operating  Cost,  as  reasonably  determined by
                 Landlord.

                 In calculating the Basic  Operating Cost,  Landlord shall apply
                 the following provision:

                     Any  category  of  costs  allocated  to  the  Buildings  in
                 question,  the other  Buildings of the Project  shall also bear
                 the burden for those  categories  of costs,  so that such costs
                 will be  uniformly  treated as Building  costs  throughout  the
                 Project, on a consistent and non-discriminatory basis. The same
                 shall apply for categories of costs allocated as Project costs.

                     Insurance   deductibles   in  excess  of  $5,000  shall  be
                 amortized  over  the  useful  life  of  the  item  repaired  or
                 replaced.  Tenant  shall not be required  to pay the  insurance
                 deductible if the damage  results from the gross  negligence or
                 willful misconduct of Landlord or Landlord's agents,  employees
                 or contractors.

                 Basic Operating Cost shall not include  specific costs incurred
                 for the account of,  separately  billed to and paid by specific
                 tenants.  Notwithstanding  anything herein to the contrary,  in
                 any instance wherein  Landlord,  in Landlord's sole discretion,
                 deems  Tenant to be  responsible  for any amounts  greater than
                 Tenant's  Proportionate Share, Landlord shall have the right to
                 allocate costs in any manner Landlord deems appropriate.

                 The  following  items  shall be excluded  from Basic  Operating
                 Costs:  loan  payments;  brokers'  and  finders'  fees or other
                 commissions;  leasing expenses; depreciation on improvements or
                 equipment  and  machinery;  expenses  for  items  which are not
                 generally of use to all  tenants;  advertising  or  promotional
                 expenses; wages, salaries,  employee benefits and payroll taxes
                 for Landlord's  personnel  (except to the extent such personnel
                 are  employed  to operate  or repair the  Project or the common
                 area);  costs  incurred  by  Landlord  in  connection  with the
                 clean-up or removal of any Hazardous  Materials  existing prior
                 to the  respective  Commencement  Dates of the Lease  Term:  or
                 costs or expenses  incurred due to violation by Landlord of any
                 term or condition of the Lease.  In addition,  Basic  Operating
                 Costs shall be reduced by insurance or other recoveries or user
                 fees.

                 B. Payment of Estimated Basic Operating Cost.  "Estimated Basic
                 Operating  Cost" for any particular  year shall mean Landlord's
                 estimate of the Basic  Operating Cost for such fiscal year made
                 prior  to  commencement  of such  fiscal  year  as  hereinafter
                 provided.  Landlord  shall  have the right from time to time to
                 revise its fiscal year and interim  accounting  periods so long
                 as the periods as so revised are reconciled  with prior periods
                 in accordance  with generally  accepted  accounting  principles
                 applied in a consistent  manner.  During the last month of each
                 fiscal  year  during  the  Term,  or  as  soon   thereafter  as
                 practicable,  Landlord  shall give Tenant written notice of the
                 Estimated  Basic  Operating  Cost for the ensuing  fiscal year.
                 Tenant shall pay Tenant's  Proportionate Share of the Estimated
                 Operating  Cost with  installments  of Base Rent for the fiscal
                 year to which the  Estimated  Basic  Operating  Cost applies in
                 monthly  installments  on the first day of each  calendar month
                 during such year, in advance.  If at any time during the course
                 of the fiscal year,  Landlord  determines  that Basic Operating
                 Cost is  projected  to  vary  from  the  then  Estimated  Basic
                 Operating  Cost by more than ten percent  (10%),  Landlord may,
                 by written  notice  to  Tenant,   revise  the  Estimated  Basic
                 Operating  Cost  for the  balance  of  such  fiscal  year,  and
                 Tenant's  monthly  installments for the  remainder of such year
                 shall be adjusted so that by the end of such fiscal year Tenant
                 has  paid  to  Landlord  Tenant's  Proportionate  Share  of the
                 revised Estimated Basic Operating Cost for such year.

                 C. Computation of  Basic  Operating  Cost  Adjustment.   "Basic
                 Operating Cost  Adjustment"  shall mean the difference  between
                 Estimated Basic Operating Cost and Basic Operating Cost for any
                 fiscal year  determined  as  hereinafter  provided.  Within one
                 hundred twenty (120) days after the end of each fiscal year, as
                 determined by Landlord,  or as soon  thereafter as practicable,
                 Landlord shall deliver to Tenant a statement of Basic Operating
                 Cost  for  the  fiscal  year  just  ended,   accompanied  by  a
                 computation  of Basic  Operating  Cost  Adjustment.  Landlord's
                 statement of Basic  Operating Costs should include a reasonable
                 line-item  breakdown and  reasonable  supporting  data. If such
                 statement  shows that  Tenant's  payment  based upon  Estimated
                 Basic Operating Cost is less than Tenant's  Proportionate Share
                 of Basic  Operating Cost, then Tenant shall pay to Landlord the
                 difference  within  twenty  (20)  days  after  receipt  of such
                 statement.  If such statement  shows that Tenant's  payments of
                 Estimated Basic  Operating Cost exceed  Tenant's  Proportionate
                 Share of Basic  Operating  Cost,  then (provided that Tenant is
                 not in default under this Lease)  Landlord  shall pay to Tenant
                 the  difference  within twenty (20) days after delivery of such
                 statement to Tenant.  If this Lease has been  terminated or the
                 Term  hereof has expired  prior to the date of such  statement,
                 then the Basic Operating Cost  Adjustment  shall be paid by the
                 appropriate  party  within  twenty  (20) days after the date of
                 delivery  of the  statement.  Should  this  Lease  commence  or
                 terminate  at any time  other  than the first day of the fiscal
                 year, Tenant's  Proportionate Share of the Basic Operating Cost
                 adjustment  shall be prorated by  reference to the exact number
                 of calendar  days during such fiscal year that this Lease is in
                 effect.

                 D. Net Lease.  This shall be a net Lease and Base Rent shall be
                 paid to  Landlord  absolutely  net of all costs  and  expenses,
                 except as specifically  provided to the contrary in this Lease.
                 The  provisions  for  payment of Basic  Operating  Cost and the
                 Basic  Operating  Cost  Adjustment  are  intended to pass on to
                 Tenant and reimburse Landlord

                 7.A. incurred in connection with the ownership, maintenance and
                 operation  of the  Building  or  Project  and  such  additional
                 facilities now and in subsequent  years as may be determined by
                 Landlord to the be necessary to the Building or Project.

                 E. Janitorial  Service.  Tenant shall be solely responsible for
                 all interior janitorial maintenance of the Premises.

                 F. Tenant  Audit.  In the event that Tenant  shall  dispute the
                 amount set forth in any  statement  provided by Landlord  under
                 Paragraph 7.B or 7.C. above,  Tenant shall have the right,  not
                 later  than  thirty  (30)  days following  the  receipt of such
                 statement  and upon  the  condition  that  Tenant  shall  first
                 deposit  with  Landlord  the full amount in  dispute,  to cause
                 Landlord's  books and records with  respect to Basic  Operating
                 Cost for such  fiscal  year to be audited by  certified  public
                 accountants  selected  by  Tenant  and  subject  to  Landlord's
                 reasonable   right  of  approval.   The  Basic  Operating  Cost
                 Adjustment shall be appropriately adjusted on the basis of such
                 audit.  If such audit  discloses  a  liability  for a refund in
                 excess  of  seven  and one  half  percent  (7.5%)  of  Tenant's
                 Proportionate  Share of the  Basic  Operating  Cost  Adjustment
                 previously  reported,  the cost of such audit shall be borne by
                 Landlord;  otherwise  the cost of  such audit shall  be paid by
                 Tenant. If Tenant shall not request an audit in accordance with
                 the provisions of this  Paragraph 7.E.  within twenty (20) days
                 after  receipt of  Landlord's  statement  provided  pursuant to
                 Paragraph  7.8.  or 7.C.,  such  statement  shall be final  and
                 binding for all purposes hereof.

                 G. Three Day  Notice.  In the event  Tenant  fails to pay Basic
                 Operating  Costs when due as Additional  Rent,  Tenant shall be
                 subject to a three (3) day notice to pay rent or quit.

   INSURANCE  8. A.  Landlord's   Insurance.   Landlord  agrees  to  the  extent
AND INDEMNI-     reasonably   available  to  maintain   insurance  insuring  the
    FICATION     Building  against  fire,  lightning,  vandalism  and  malicious
                 mischief  (including,  if Landlord elects, "All Risk" coverage,
                 earthquake, and/or flood insurance), in an amount not less than
                 eight  percent  (80%) of the  replacement  cost  thereof,  with
                 deductibles  and the form and  endorsements of such coverage as
                 selected  by  Landlord.  Any cost  associated  with  Landlord's
                 procurement of "All Risk"  coverage,  earthquake,  and/or flood
                 insurance  shall  be  passed  through  to  Tenant  as  a  Basic
                 Operating Cost if such  insurance is available at  commercially
                 reasonable  rates. In addition Landlord shall procure insurance
                 against  loss of Base Rent and  Additional  Rent,  in an amount
                 equal to the amount of Base Rent and Additional Rent payable by
                 Tenant for a period of at least  twelve (12) months  commencing
                 on  the  date  of  loss  if  such  insurance  is  available  at
                 commercially  reasonable rates. Such insurance shall be for the
                 sole benefit of Landlord  and under  Landlord's  sole  control.
                 Landlord  shall  not be  obligated  to  insure  any  furniture,
                 equipment,  machinery,  goods or supplies which Tenant may keep
                 or maintain in the  Premises,  or any  leasehold  improvements,
                 additions or alterations within the Premises. Landlord may also
                 carry such other  insurance  as  Landlord  may deem  prudent or
                 advisable,  including, without limitation,  liability insurance
                 in such amounts and on such terms as Landlord shall determine. 
                                                                                
                 B. Tenant's Insurance.

                 (1)Property  Insurance.  Tenant shall  procure at Tenant's sole

                 and at all times  until the end of the Term,  insurance  on all
                 personal  property and fixtures of Tenant and all  improvements
                 made by or for Tenant to the  Premises,  insuring such property
                 for the full replacement value of such property.

                 (2)Liability  Insurance.  Tenant shall procure at Tenant's sole
                 cost and expense and keep in effect from the date of this Lease
                 and  at  all  times   until   the   end  of  the  Term   either
                 Comprehensive General Liability Insurance or Commercial General
                 Liability  insurance  applying to the use and  occupancy of the
                 Premises  and the  Building,  and any part of  either,  and any
                 areas adjacent thereto, and the business operated by Tenant, or
                 by any other  occupant on the Premises.  Such  insurance  shall
                 include Broad Form  Contractual  Liability  insurance  coverage
                 insuring Tenant's indemnity  obligations under this Lease. Such
                 coverage  shall  have  a  minimum   combined  single  limit  of
                 liability of at least One Million Dollars ($1,000,000.00),  and
                 a  general   aggregate   limit  of  One   Million   Dollars  ($
                 1,000,000.00).  All such policies  shall be written to apply to
                 bodily injury,  property  damage or loss,  personal  injury and
                 other covered loss,  however  occasioned,  occurring during the
                 policy  term,  shall be endorsed to add  Landlord and any party
                 holding an interest to which this Lease may be  subordinated as
                 an  additional  insured,  and shall  provide that such coverage
                 shall be primary and that any insurance  maintained by Landlord
                 shall be  excess  insurance  only.  Such  coverage  shall  also
                 contain  endorsements:  (i)  including  employees as additional
                 insureds;  (ii) deleting any liquor  liability  exclusion;  and
                 (iii)   providing   for  coverage  of   employer's   automobile
                 non-ownership  liability.  All such insurance shall provide for
                 severability  of interests;  and shall afford  coverage for all
                 claims  based on acts,  omissions,  injury  and  damage,  which
                 claims  occurred  or arose (or the onset of which  occurred  or
                 arose)  in whole or in part  during  the  policy  period.  Said
                 coverage  shall  be  written  on  an  "occurrence"   basis,  if
                 available.  If an  "occurrence"  basis  form is not  available,
                 Tenant must  purchase  "tail"  coverage  for the most number of
                 years available,  and tenant must also purchase "tail" coverage
                 if the  retroactive  date of a policy  form is changed so as to
                 leave  a gap  in  coverage  for  occurrences  that  might  have
                 occurred  in prior  years.  If a "claims  made"  policy is ever
                 used, the policy must be endorsed so that Landlord is given the
                 right to purchase  "tail" coverage should Tenant for any reason
                 not do so or if the policy is to be canceled for  nonpayment of
                 premium, provided such endorsement is available at commercially
                 reasonable rates.

                     (3) General Insurance Requirements. All coverages described
                 in this Paragraph  8.B.  shall be endorsed to provide  Landlord
                 with  thirty  (30) days'  notice of  cancellation  or change in
                 terms. If at any time during the Term the amount or coverage of
                 insurance   which  Tenant  is  required  to  carry  under  this
                 Paragraph 8.B. is, in Landlord's

                 reasonable judgment, materially less than the amount or type of
                 insurance  coverage  typically  carried by owners or tenants of
                 properties  located in the general  area in which the  Premises
                 are  located  which are  similar to and  operated  for  similar
                 purposes as the Premises, Landlord shall have to require Tenant
                 to  increase  the  amount  or  change  the  types of  insurance
                 coverage  required  under this  Paragraph  8.B.  All  insurance
                 policies  required  to be carried  under  this  Lease  shall be
                 written by companies  rated A-V or better in "Best's  Insurance
                 Guide"  and  authorized  to  do  business  in  California.  Any
                 deductible   amounts  under  any  insurance  policies  required
                 hereunder   shall  be  subject  to  Landlord's   prior  written
                 approval.  In any event deductible amounts shall not exceed Ten
                 Thousand Dollars ($10,000.00). Tenant shall deliver to Landlord
                 on or before the Term  Commencement  Date,  and  thereafter  at

                 expiring  policies,  certified  copies  of  Tenant's  insurance
                 policies,  or a certificate  evidencing  the same issued by the
                 insurer  thereunder,  showing that all premiums  have been paid
                 for the full policy period; and, in the event Tenant shall fail
                 to procure  such  insurance,  or to deliver  such  policies  or
                 certificates,  Landlord  may,  as  an  additional  insured,  at
                 Landlord's  option and in addition to Landlord's other remedies
                 in the event of a default by Tenant hereunder, procure the same
                 for the account of Tenant,  and the cost thereof  shall be paid
                 to Landlord as Additional Rent.

                 C. Indemnification.  Landlord shall not be liable to Tenant for
                 any loss or damage to person or property caused by theft, fire,
                 acts  of  God,   acts  of  a  public   enemy,   riot,   strike,
                 insurrection,   war,  court  order,  requisition  or  order  of
                 governmental   body  or   authority   or  for  any   damage  or
                 inconvenience  which may arise through  repair or alteration of
                 any part of the Building or Project or failure to make any such
                 repair, except as expressly otherwise provided in Paragraph 10.
                 Tenant  shall  indemnify,   defend  by  counsel  acceptable  to
                 Landlord,  protect and hold Landlord  harmless from and against
                 any and all liabilities,  losses, costs,  damages,  injuries or
                 expenses, including reasonable attorneys' fees and court costs,
                 arising  out of or related to: (1) claims of injury to or death
                 of  persons  or  damage  to  property  occurring  or  resulting
                 directly  or  indirectly  from  the  use  or  occupancy  of the
                 Premises,  or from  activities of Tenant,  Tenant's  Parties or
                 anyone in or about the  Premises or Project,  or (2) claims for
                 work or labor performed, or for materials or supplies furnished
                 to or at the request of Tenant in connection  with  performance
                 of any work done for the  account of Tenant in the  performance
                 of  any  covenant   contained  in  this  Lease.  The  foregoing
                 indemnity  shall not be applicable  to claims  arising from the
                 active  negligence  or  willful  misconduct  of  Landlord.  The
                 provisions of this  Paragraph  shall survive the  expiration or
                 termination  of  this  Lease  with  respect  to any  claims  or
                 liability occurring prior to such expiration or termination.

  WAIVER OF   9.     To the extent  permitted by law and without  affecting  the
   SUBROGA-      coverage  provided by  insurance  to be  maintained  hereunder,
       TION      Landlord and Tenant each waive any right to recover against the
                 other for:  (a) damages for injury to or death of persons;  (b)
                 damages to  property;  (c) damages to the  Premises or any part
                 thereof,  and (d) claims arising by reason of the foregoing due
                 to hazards  covered  by  insurance  to the  extent of  proceeds
                 recovered therefrom. This provision is intended to waive fully,
                 and for the benefit of each  party,  any rights  and/or  claims
                 which might give rise to a right of subrogation in favor of any
                 insurance carrier. The coverage obtained by each party pursuant
                 to this Lease shall include,  without  limitation,  a waiver of
                 subrogation  by the carrier which conforms to the provisions of
                 this paragraph.

                 any act of Tenant may be repaired  by  Landlord  at  Landlord's
                 option and at Tenant's  expense.  Tenant shall immediately give
                 Landlord  written notice of any defect or need of repairs after
                 which  Landlord  shall have a reasonable  opportunity to repair
                 same.   Landlord's  liability  with  respect  to  any  defects,
                 repairs, or maintenance for which Landlord is responsible under
                 any of the  provisions  of this  Lease  shall be limited to the
                 cost of such repairs or maintenance.
              
   TENANT'S   11.    Tenant shall at Tenant's  expense maintain all parts of the
    REPAIRS      Premises in a good clean and secure condition and promptly make

                 preventative  maintenance/service  contract  with a maintenance
                 contractor  for  servicing  all  hot  water,  heating  and  air

ALTERATIONS  12.     Excepting   non-structural   alterations  to  the  Premises
                 costing less than five  thousand  dollars  ($5,000.00),  Tenant
                 shall  not  make,  or  allow  to be made,  any  alterations  or
                 physical  additions  in,  about  or  to  the  Premises  without
                 obtaining the prior written consent of Landlord,  which consent
                 shall not be  unreasonably  withheld  with  respect to proposed
                 alterations and additions which: (a) comply with all applicable
                 laws, ordinances,  rules and regulations; (b) are in Landlord's
                 opinion   compatible  with  the  Project  and  its  mechanical,
                 plumbing,  electrical,   heating/ventilation/air   conditioning
                 systems;  and (c) will not interfere with the use and occupancy
                 of any other  portion of the  Building  or Project by any other
                 tenant or its invitees.  Specifically, but without limiting the
                 generality of the  foregoing,  Landlord shall have the right of
                 written  consent  for  all  plans  and  specifications  for the
                 proposed  alterations  or  additions,  construction  means  and
                 methods,  all appropriate permits and licenses,  any contractor
                 or  subcontractor  to be employed on the work of alterations or
                 additions,  and the time for  performance of such work.  Tenant
                 shall also supply to Landlord  any  documents  and  information
                 reasonably  requested by Landlord in connection with Landlord's
                 consideration of a request for approval hereunder. Tenant shall
                 reimburse  Landlord  for all costs which  Landlord may incur in
                 connection  with the  granting  approval to Tenant for any such
                 alterations  and  additions,  including  any costs or  expenses
                 which Landlord may incur in electing to have outside architects
                 and engineers  review said plans and  specifications.  All such
                 alterations,  physical  additions or improvements  shall remain
                 the  property of Tenant  until  termination  of this Lease,  at
                 which time they shall be and become the property of Landlord if
                 Landlord so elects;  provided,  however,  that Landlord may, at
                 Landlord's  option,  require that Tenant,  at Tenant's expense,
                 remove  any or all  alterations,  additions,  improvements  and
                 partitions  made by Tenant  and  restore  the  Premises  by the
                 termination  of this  Lease,  whether  by  lapse  of  time,  or
                 otherwise,   to   their   condition   existing   prior  to  the
                 construction of any such alterations,  additions, partitions or
                 leasehold improvements. All such removals and restoration shall
                 accomplished  in a good  and  workmanlike  manner  so as not to
                 cause any  damage to the  Premises  or Project  whatsoever.  If
                 Tenant  fails  to  so  remove  such   alterations,   additions,
                 improvements  and  partitions  or  Tenant's  trade  fixtures or
                 furniture, Landlord may keep and use them or remove any of them
                 and  cause  them  to be  stored  or  sold  in  accordance  with
                 applicable  law, at Tenant's sole  expense.  In addition to and
                 wholly  apart  from  Tenant's   obligations   to  pay  Tenant's
                 Proportionate  Share of Basic Operating  Cost,  Tenant shall be
                 responsible for and shall pay prior to delinquency any taxes or
                 governmental  service fees,  possessory interest taxes, fees or
                 charges in lieu of any such  taxes,  capital  levies,  or other
                 charges  imposed  upon,  levied  with  respect  to or  assessed
                 against its personal property, on the value of the alterations,
                 additions or improvements within the Premises,  and on Tenant's
                 interest  pursuant to this  Lease.  To the extent that any such
                 taxes are not separately  assessed or billed to Tenant,  Tenant
                 shall pay the amount thereof as invoiced to Tenant by Landlord.
                 Tenant,  at its own cost and  expense  and  without  Landlord's
                 prior  approval may erect such  shelves,  bins,  machinery  and
                 trade fixtures  (collectively "Trade Fixtures") in the ordinary
                 course  of its  business  provided  that  such do not alter the
                 basic character of the Premises,  do not overload or damage the
                 Premises,  and may be removed  without  injury to the Premises,
                 and  the  construction,   erection,  and  installation  thereof
                 complies  with  all  Legal  Requirements  and  with  Landlord's
                 requirements  set forth  above.  Tenant  shall remove its Trade
                 Fixtures and shall repair any damage caused by such removal.

SIGNS        13.     Landlord  shall allow at Tenant's sole cost and expense the
                 installation of building  signage subject to Landlord's and the
                 City of San  Carlos's  approval  and  consistent  with  the San
                 Carlos  Business  Park's current signage program as outlined by
                 the Project's Sign Criteria,  attached  hereto as Exhibit D and
                 incorporated  by this reference.  Any  installation of signs or
                 graphics on or about the Premises and Project  shall be subject
                 to any applicable  governmental laws,  ordinances,  regulations
                 and to any other requirements imposed by Landlord. Tenant shall
                 remove all such signs and graphics prior to the  termination of
                 this Lease.  Such  installations  and removals shall be made in
                 such manner as to avoid injury or  defacement  of the Premises,
                 Building  or Project  and any other  limitation,  discoloration
                 caused by such installation or removal.

INSPECTION/  14.     After  reasonable  notice,  except in emergencies  where no
    POSTING      such notice shall be required,  Landlord, and Landlord's agents
    NOTICES      and representatives, shall have the right to enter the Premises
                 to inspect the same,  to clean,  to perform such work as may be
                 permitted or required hereunder, to make repairs or alterations
                 to the Premises or Project or to other tenant  spaces  therein,
                 to deal  with  emergencies,  to  post  such  notices  as may be
                 required  by law to prevent  the  perfection  of liens  against
                 Landlord's  interest in the Project or to exhibit the  Premises
                 to prospective tenants, purchasers, encumbrancers or others, or
                 for any  other  purpose  as  Landlord  may  deem  necessary  or
                 desirable;   provided,   however,   that  Landlord   shall  use
                 reasonable efforts not to unreasonably  interfere with Tenant's
                 business  operations.  Tenant  shall  not  be  entitled  to any
                 abatement  of Rent by reason of the  exercise of any such right
                 of entry. At any time within six (6) months prior to the end of
                 the  Term,  Landlord  shall  have  the  right  to  erect on the
                 Premises  and/or  Project a suitable sign  indicating  that the
                 Premises  are  available  for lease.  Tenant shall give written
                 notice to Landlord at least  thirty (30) days prior to vacating
                 the  Premises  and  shall  meet  with   Landlord  for  a  joint
                 inspection  of the  Premises  at the time of  vacating.  In the
                 event of Tenant's failure to give such notice or participate in
                 such  joint  inspection,  Landlord's  inspection  at  or  after
                 Tenant's  vacating the Premises  shall  conclusively  be deemed
                 correct for purposes of determining Tenant's responsibility for
                 repairs and restoration.
              

UTILITIES    15.     Tenant  shall pay directly for all water,  gas,  heat,  air
                 conditioning, light, power, telephone, sewer, sprinkler charges
                 and other  utilities and services used on or from the Premises,
                 together  with any  taxes,  penalties,  surcharges  or the like
                 pertaining  thereto,  and maintenance charges for utilities and
                 shall furnish all electric light bulbs,  ballasts and tubes. If
                 any such services are not separately metered to Tenant,  Tenant
                 shall pay a reasonable  proportion,  as determined by Landlord,
                 of all charges jointly  serving other premises.  Landlord shall
                 not be liable for any damages directly or indirectly  resulting
                 from nor shall the Rent or any monies owed Landlord  under this
                 Lease  herein   reserved  be  abated  by  reason  of:  (a)  the
                 installation,  use or interruption of use of any equipment used
                 in  connection  with the  furnishing  of any such  utilities or
                 services; (b) the failure to furnish or delay in furnishing any
                 such utilities or

                 of national,  state or local  governmental  agencies or utility
                 suppliers in reducing energy or other resource consumption. The
                 obligation  to  make  services  available  hereunder  shall  be
                 subject to the  limitations of any such  voluntary,  reasonable
                 program.  Notwithstanding  the  foregoing,  in  the  event  any
                 interruption  of  utilities or Building  services  specified in
                 this Paragraph 15 continues for more than seven (7) consecutive
                 days,  and the  Premises  are  rendered  unusable  for Tenant's
                 proposed  use, then Rent shall be abated for the time period of
                 such interruption.

 SUBORDI-   16.      Without the  necessity  of any  additional  document  being
   NATION        executed   by  Tenant   for  the   purpose   of   effecting   a
                 subordination,  the Lease shall be subject and  subordinate  at
                 all times to: (a) all ground leases or underlying  leases which
                 may now exist or hereafter be executed  affecting  the Premises
                 and/or  the land  upon  which  the  Premises  and  Project  are
                 situated,  or both; and (b) any mortgage or deed of trust which
                 may now exist or be  placed  upon said  Project,  land,  ground
                 leases or underlying  leases, or Landlord's  interest or estate
                 in  any  said   items   which   is   specified   as   security.
                 Notwithstanding the foregoing, Landlord shall have the right to
                 subordinate or cause to be subordinated  any such ground leases
                 or  underlying  leases or any such liens to this Lease.  In the
                 event that any ground lease or underlying  lease terminates for
                 any reason or any mortgage or deed of trust is  foreclosed or a
                 conveyance  in lieu of  foreclosure  is  made  for any  reason,
                 Tenant shall, notwithstanding any subordination,  attorn to and
                 become the Tenant of the  successor  in interest to Landlord at
                 the option of such successor in interest.  Within ten (10) days
                 after request by Landlord, Tenant shall execute and deliver any
                 additional  documents  evidencing  Tenant's  attornment  or the
                 subordination  of this  Lease with  respect to any such  ground
                 leases or  underlying  leases or any such  mortgage  or deed of
                 trust,  in the form  requested  by  Landlord  or by any  ground
                 landlord,  mortgagee,  or  beneficiary  under a deed of  trust.
                 Landlord shall use its best efforts to obtain a non-disturbance
                 agreement  for Tenant's  benefit but shall have no liability if
                 its lender fails to do so. Landlord's equity in the property is
                 several million dollars.


 FINANCIAL   17.     At  the  request  of  Landlord,  Tenant  shall  provide  to
STATEMENTS       Landlord   Tenant's  current   financial   statement  or  other
                 information   discussing   financial  worth  of  Tenant,  which
                 Landlord  shall use  solely for  purposes  of this Lease and in
                 connection  with the ownership,  management and  disposition of
                 the Project.

   ESTOPPEL  18.     Tenant agrees from time to time, within ten (10) days after
CERTIFICATE      request of  Landlord,  to deliver to  Landlord,  or  Landlord's
                 designee, an estoppel certificate stating that this Lease is in
                 full  force and  effect,  the date to which Rent has been paid,
                 the  unexpired  portion of this Lease,  and such other  matters
                 pertaining  to this  Lease as may be  reasonably  requested  by
                 Landlord.  Failure  by  Tenant  to  execute  and  deliver  such
                 certificate  shall constitute an acceptance of the Premises and
                 acknowledgment by Tenant that the statements  included are true
                 and correct without exception.  Landlord and Tenant intend that
                 any  statement  delivered  pursuant  to this  Paragraph  may be
                 relied  upon  by  any  mortgagee,  beneficiary,   purchaser  or
                 prospective  purchaser of the Project or any interest  therein.
                 The parties  agree that  Tenant's  obligation  to furnish  such
                 estoppel  certificates  in  a  timely  fashion  is  a  material
                 inducement for Landlord's  execution of the Lease, and shall be
                 an event of default  if Tenant  fails to fully  comply.  Tenant
                 shall indemnify  Lessor for any loss caused by Tenant's failure
                 to  timely   execute   an   estoppel   certificate,   including
                 consequential  damages such as loss of financing or refinancing
                 or  loss of a  potential  sale of the  Property,  all of  which
                 events are deemed foreseeable by the parties to this Lease.
              

   SECURITY  19.     Tenant agrees to deposit with  Landlord  upon  execution of
    DEPOSIT      this  Lease,  a Security  Deposit as stated in the Basic  Lease
                 Information,  which  sum  shall  be held by  Landlord,  without
                 obligation  for interest,  as security for the  performance  of
                 Tenant's  covenants  and  obligations  under  this  Lease.  The
                 Security  Deposit is not an advance rental deposit or a measure
                 of damages  incurred by  Landlord in case of Tenant's  default.
                 Upon the occurrence of any event of default by Tenant, Landlord
                 may, from time to time,  without  prejudice to any other remedy
                 provided herein or provided by law, use such fund to the extent
                 necessary  to make good any  arrears of Rent or other  payments
                 due to  Landlord  hereunder,  and  any  other  damage,  injury,
                 expense  or  liability  caused by such  event of  default,  and
                 Tenant shall pay to Landlord,  on demand, the amount so applied
                 in  order to  restore  the  Security  Deposit  to its  original
                 amount.  Although  the  Security  Deposit  shall be deemed  the
                 property of  Landlord,  any  remaining  balance of such deposit
                 shall be  returned  by  Landlord  to Tenant at such time  after
                 termination  of this  Lease  that all of  Tenant's  obligations
                 under  this  Lease have been  fulfilled.  Landlord  may use and
                 commingle the Security Deposit with other funds of Landlord.
                                                                                
   TENANT'S  20.     The  liability  of  Landlord  to Tenant for any  default by
   REMEDIES      Landlord  under  the  terms  of this  Lease  are  not  personal
                 obligations  of the  individual or other  partners,  directors,
                 officers and  shareholders  of Landlord,  and Tenant  agrees to
                 look  solely to  Landlord's  interest  in the  Project  for the
                 recovery  of any amount  from  Landlord,  and shall not look to
                 other assets of Landlord nor seek  recourse  against the assets
                 of the  individual or other  partners,  directors  officers and
                 shareholders of Landlord. Any lien obtained to enforce any such
                 judgment and any levy of execution thereon shall be subject and
                 subordinate  to any  lien,  mortgage  or deed of  trust  on the
                 Project.
 
    ASSIGN-  21. A.  General.  Tenant shall not assign or sublet the Premises or
   MENT AND      any part thereof  without  Landlord's  prior written  approval,
 SUBLETTING      such approval not to be unreasonably  withheld,  conditioned or
                 delayed except as provided herein.  If Tenant desires to assign
                 this Lease or sublet any or all of the  Premises,  Tenant shall
                 give Landlord written notice  forty-five (45) days prior to the
                 anticipated  effective  date  of the  assignment  or  sublease.
                 Landlord  shall  then  have  a  period  of  fifteen  (15)  days
                 following  receipt of such  notice to notify  Tenant in writing
                 that Landlord elects either:

                 (1) to  terminate  this Lease as to the space so affected as of
                 the date so requested by Tenant; or (2) to permit Tenant assign
                 this  Lease  or  sublet  such  space,   subject,   however,  to
                 Landlord's prior written  approval of the proposed  assignee or
                 subtenant and of any related documents or agreements associated
                 with the  assignment  or sublease.  If Landlord  should fail to
                 notify Tenant in writing of such  election  within said period,
                 Landlord  shall be deemed to have waived option (1) above,  but
                 written  approval  by  Landlord  of the  proposed  assignee  or
                 subtenant shall be required.  If Landlord does not exercise the
                 option provided in subitem (1) above,  Landlord's  consent to a
                 proposed   assignment  or  sublet  shall  not  be  unreasonably
                 withheld.  Without limiting the other instances in which it may
                 be reasonable for Landlord to withhold Landlord's consent to an
                 assignment or subletting,  Landlord and Tenant acknowledge that
                 it shall be  reasonable  for  Landlord to  withhold  Landlord's
                 consent in the following instances:  The use of the Premises by
                 such  proposed  assignee or subtenant  would not be a permitted
                 use or would increase the Parking  Density of the Project;  the
                 proposed  assignee  or  subtenant  is  not of  sound  financial
                 condition; the proposed assignee or subtenant is a governmental
                 agency; the proposed assignee or subtenant does not have a good
                 reputation  as a tenant of property;  the proposed  assignee or
                 subtenant  is a person  with whom  Landlord is  negotiating  to
                 lease space in the Project;  the assignment or subletting would
                 entail  any  alterations  which  would  lessen the value of the
                 leasehold  improvements  in the  Premises;  or if  Tenant is in
                 default of any obligation of Tenant under this Lease, or Tenant
                 has defaulted  under this Lease on three (3) or more  occasions
                 during any twelve  months  preceding the date that Tenant shall
                 request  consent.  Failure  by  Landlord  to approve a proposed
                 assignee or  subtenant  shall not cause a  termination  of this
                 Lease. Upon a termination under this Paragraph 21.A.,  Landlord
                 may lease the  Premises to any party,  including  parties  with
                 whom Tenant has  negotiated an assignment or sublease,  without
                 incurring any liability to Tenant.

                 B. Bonus  Rent.  Any Rent or other  consideration  realized  by
                 Tenant under any such  sublease or  assignment in excess of the
                 Rent  payable  hereunder,  after  amortization  of a reasonable
                 brokerage  commission  shall be  divided and paid, ten  percent
                 (10%) to  Tenant,  ninety  percent  (90%) to  Landlord.  In any
                 subletting  or assignment  undertaken  by Tenant,  Tenant shall
                 diligently  seek to obtain the maximum rental amount  available
                 in the marketplace for such subletting or assignment.

                 C.  Corporation.  If Tenant is a  corporation,  a  transfer  of
                 corporate  shares by sale,  assignment,  bequest,  inheritance,
                 operation  of  law  or  other  disposition  (including  such  a
                 transfer  to or by a  receiver  or  trustee in federal or state
                 bankruptcy,  insolvency or other proceedings),  so as to result
                 in a change in the present  control of such  corporation or any
                 of its parent  corporations  by the person or persons  owning a
                 majority  of  said  corporate   shares,   shall  constitute  an
                 assignment for purposes of this Lease.

                 Landlord's   prior  consent  shall  not  be  required  for  any
                 assignment or sublease of Tenant's  interest in the Premises or
                 the Lease to any  corporation  with  which  Tenant may merge or
                 consolidate  or  become  affiliated  as a  parent,  subsidiary,
                 holding  company or otherwise,  or to an entity in which Tenant
                 has a  controlling  interest  provided  such entity's net worth
                 exceeds Tenant's net worth.

                 D.  Partnership.  If Tenant is a partnership,  joint venture or
                 other incorporated business form, a transfer of the interest of
                 persons,  firms or entities  responsible for managerial control
                 of Tenant by sale, assignment, bequest, inheritance,  operation
                 of law or other disposition, so as to result in a change in the
                 present  control of said entity and/or a change in the identity
                 of the persons  responsible for the general credit  obligations
                 of said entity shall  constitute an assignment for all purposes
                 of this Lease.

                 E. Liability.  Except as otherwise  provided,  no assignment or
                 subletting  by Tenant shall  relieve  Tenant of any  obligation
                 under this Lease.  Any assignment or subletting which conflicts
                 with the provisions hereof shall be void.

  AUTHORITY  22.        Landlord  represents  and  warrants  that  it  has  full
 OF PARTIES      right and  authority  to enter into this  Lease  and to perform
                 all of Landlord's obligations hereunder.  Tenant represents and
                 warrants  that it has full  right and  authority  to enter into
                 this  Lease  and  to  perform  all  of   Tenant's   obligations
                 hereunder.
               
    CONDEM-  23. A. Condemnation  Resulting in Termination.  If the whole or any
     NATION      substantial  part of the  Project of which the  Premises  are a
                 part  should be taken or  condemned  for any  public  use under
                 governmental  law,  ordinance  or  regulation,  or by  right of
                 eminent domain, or by private purchase in lieu thereof, and the
                 taking would prevent or materially interfere with the Permitted
                 Use of the  Premises,  this Lease shall  terminate and the Rent
                 shall be abated  during the  unexpired  portion of this  Lease,
                 effective when the physical  taking of said Premises shall have

                 terminated  as provided in Paragraph  23.A.  above,  this Lease
                 shall not terminate,  but the Rent payable hereunder during the
                 unexpired  portion of the Lease shall be reduced,  beginning on
                 the date when the physical taking shall have occurred,  to such
                 amount  as  may  be  fair  and  reasonable  under  all  of  the
                 circumstances.

                 C. Award.  Landlord  shall be entitled to any and all  payment,
                 income,  rent, award, or any interest therein  whatsoever which

                 conveyance  and Tenant shall have no claim against  Landlord or

                 Landlord  shall not be required  to rebuild,  repair or replace
                 any  part  of the  partitions,  fixtures  additions  and  other
                 leasehold  improvements  which may have been  placed  in, on or
                 about the Premises.  If the Premises are  untenantable in whole
                 or in part  following such damage,  the Rent payable  hereunder
                 during  the  period  in which  they are  untenantable  shall be
                 abated  proportionately,  but  only  to the  extent  of  rental
                 abatement  insurance  proceeds  received by Landlord during the
                 time and to the extent the Premises are unfit for occupancy. If
                 Landlord's  insurer fails to make timely  payment of an insured
                 loss,  Landlord's  obligation will be abated for such period of
                 delay, not to exceed thirty (30) days.

                 C. Greater than 180 Days. If the Premises or Building should be
                 damaged  by fire,  tornado or other  casualty  but only to such
                 extent that rebuilding or repairs can in Landlord's  estimation
                 be  reasonably  completed  in more than one  hundred and eighty
                 (180) days, then Landlord shall have the option of either:  (1)
                 terminating the Lease effective upon the date of the occurrence
                 of such damage,  in which event the Rent shall be abated during
                 the unexpired  portion of the Lease; or (2) electing to rebuild
                 or repair the Premises to substantially  the condition in which
                 they existed  prior to such  damage,  provided  that  insurance
                 proceeds are available, to fully repair the damage, except that
                 Landlord  shall not be required  to rebuild,  repair or replace
                 any  part of the  partitions,  fixtures,  additions  and  other
                 improvements  which  may have been  placed  in, on or about the
                 Premises.  If the Premises are untenantable in whole or in part
                 following such damage,  the Rent payable  hereunder  during the
                 period  in  which  they  are   untenantable   shall  be  abated
                 proportionately,  but only to the  extent of  rental  abatement
                 insurance  proceeds received by Landlord during the time and to
                 the extent the Premises are unfit for  occupancy.  In the event
                 that  Landlord   should  fail  to  complete  such  repairs  and
                 rebuilding  within one hundred  eight (180) days after the date
                 upon which Landlord is notified by Tenant of such damage,  such
                 period of time to be extended for delays caused by the fault or
                 neglect  of Tenant or  because  of acts of God,  acts of public
                 agencies,  labor disputes,  strikes,  fires, freight embargoes,
                 rainy or story weather, inability to obtain materials, supplies
                 or fuels, or delays of the contractors or subcontractors or any
                 other causes or contingencies  beyond the reasonable control of
                 Landlord,  Tenant may at Tenant's  option  within ten (10) days
                 after  the  expiration  of such one  hundred  eighty  (180) day
                 period  (as  such may be  extended),  terminate  this  Lease by
                 delivering   written  notice  of  termination  to  Landlord  as
                 Tenant's exclusive remedy, whereupon all rights hereunder shall
                 cease and terminate thirty (30) days after  Landlord's  receipt
                 of such termination notice.

                 D. Tenant's  Fault. If the Premises or any other portion of the
                 Building are damaged by fire or other  casualty  resulting from
                 the fault,  negligence,  or breach of this Lease by Tenant,  or
                 Tenant's  Parties,  Base Rent and Additional  Rent shall not be
                 diminished  during  the  repair  of such  damage,  except to an
                 amount  recovered  by  Landlord  through  any rental  abatement
                 insurance,  and Tenant shall be liable to Landlord for the cost
                 and  expense  of the  repair and  restoration  of the  Building
                 caused  thereby  to the  extent  such cost and  expense  is not
                 covered by insurance proceeds.

                 F. Uninsured Casualty.  Notwithstanding  anything herein to the
                 contrary,  in the  event  that the  Premises  or  Building  are
                 damaged or destroyed and are not fully covered by the insurance
                 proceeds  received  by Landlord or in the event that the holder
                 of any  indebtedness  secured  by  mortgage  or deed  of  trust
                 covering the Premises  requires that the insurance  proceeds be
                 applied  to such  indebtedness,  then in either  ease  Landlord
                 shall  have the right to  terminate  this  Lease by  delivering
                 written notice of termination to Tenant within thirty (30) days
                 after  the date of  notice  to  Landlord  that  said  damage or
                 destruction   is  not  fully   covered  by  insurance  or  such
                 requirement  is made by any  such  holder,  as the case may be,
                 whereupon all rights and obligations  hereunder shall cease and
                 terminate.

                 G. Waiver.  Except as otherwise  provided in this Paragraph 24,
                 Tenant  hereby  waives  the  provisions  of  Sections  1932(a),
                 1933(4), 1941 and 1942 of the Civil Code of California.

    HOLDING  25. If   Tenant  shall  retain   possession   of  the  Premises  or
       OVER      any portion thereof without  Landlord's  consent  following the
                 expiration of the Lease or sooner  termination  for any reason,
                 then  Tenant  shall  pay to  Landlord  for  each  day  of  such
                 retention  triple the amount of the daily rental as of the last
                 month prior to the date of  expiration or  termination.  Tenant
                 shall  also  indemnify,   defend,  protect  and  hold  Landlord
                 harmless from any loss, liability or cost, including reasonable
                 attorneys' fees, resulting form delay by tenant in surrendering
                 the Premises, including, without limitation, any claims made by
                 any succeeding tenant founded on such delay. Acceptance of Rent
                 by  Landlord  following  expiration  or  termination  shall not
                 constitute  a renewal of this Lease,  and nothing  contained in
                 this  Paragraph 25 shall waive  Landlord's  right or reentry or
                 any  other  right.  Unless  Landlord  consents  in  writing  to
                 Tenant's  holding  over,  Tenant  shall  be  only a  Tenant  at
                 sufferance,  whether  or not  Landlord  accepts  any Rent  from
                 Tenant while Tenant is holding over without  Landlord's written
                 consent.  Additionally,  in the event that upon  termination of
                 the Lease, Tenant has not fulfilled its obligation with respect
                 to repairs and cleanup of the Premises or any other Tenant

<PAGE>

                 obligations  as set forth in this Lease,  then  Landlord  shall
                 have the  right to  perform  any such  obligations  as it deems
                 necessary  at  Tenant's  sole  cost and  expense,  and any time
                 required  by Landlord to  complete  such  obligations  shall be
                 considered  a period  of  holding  over  and the  terms of this
                 Paragraph 25 shall apply.

   DEFAULT  26.  A. Events of Default.  The  occurrence  of any of the following
                 shall constitute an event of default on the part of Tenant:

                 (1) Abandonment.  Abandonment  of the Premises for a continuous
                 period in excess of five (5) days "unless  Tenant  continues to
                 pay rent and perform all other  obligations of Tenant  required
                 under  this  Lease,  in  which  case  Tenant  shall  not  be in
                 default."  Tenant  waives  any right to notice  Tenant may have
                 under  Section  1951.3  of  the  Civil  Code  of the  State  of
                 California, the terms of this Paragraph 26.A. being deemed such
                 notice to Tenant as required by said Section 1951.3.

                 (2)  Nonpayment of Rent.  Failure to pay any instalment of Rent
                 or any other  amount due and  payable  hereunder  upon the date
                 when said  payment is due, and such failure is not cured within
                 five (5) days notice from Landlord specifying such failure.

                 (3) Other  Obligations.  Failure  to  perform  any  obligation,
                 agreement or covenant under this Lease other than those matters
                 specified in subparagraphs  (1) and (2) of this Paragraph 26.A,
                 such failure  continuing  for fifteen  (15) days after  written
                 notice of such failure,  provided,  however, that if the nature
                 of Tenant's  default is such that more than  fifteen  (15) days
                 are reasonably  required for its cure, then Tenant shall not be
                 deemed  to be in  default  under  this  Lease if  Tenant  shall
                 commence the cure of such default  within said fifteen (15) day
                 period  and use his  best  efforts  to  prosecute  the  same to
                 completion.

                 (4) General Assignment.  A general assignment by Tenant for the
                 benefit of credits.

                 (5) Bankruptcy.  The  filing  of  any  voluntary   petition  in
                 bankruptcy by Tenant, or the filing of an involuntary  petition
                 by  Tenant's  creditors,  which  involuntary  petition  remains
                 undischarged  for a period of thirty  (30)  days.  In the event
                 that under  applicable  law the trustee in bankruptcy or Tenant
                 has the right to affirm this Lease and  continue to perform the
                 obligations of Tenant hereunder,  such trustee or Tenant shall,
                 in such time period as may be permitted by the bankruptcy court
                 having  jurisdiction,  cure all  defaults  of Tenant  hereunder
                 outstanding  as of the date of the affirmance of this Lease and
                 provide  to  Landlord  such  adequate   assurances  as  may  be
                 necessary to ensure  Landlord of the continued  performance  of
                 Tenant's obligations under this Lease.

                 (6) Receivership.   The   employment  of  a  receiver  to  take
                 possession  of  substantially  all of  Tenant's  assets  or the
                 Premises,   if  such   appointment   remains   undismissed   or
                 undischarged  for a period  often  (10)  days  after  the order
                 therefor.

                 (7) Attachment.  The  attachment, execution  or other  judicial
                 seizure of all or  substantially  all of Tenant's assets or the
                 Premises,   if  such   attachment  or  other  seizure   remains
                 undismissed or undischarged for a period of ten (10) days after
                 the levy thereof.

                 B. Remedies Upon Default.

                 (1) Termination. In the event of the occurrence of any event of
                 default (and such default  remains uncured after the expiration
                 of any applicable cure period provided herein),  Landlord shall
                 have the right to give a written  termination notice to Tenant,
                 and on the date  specified  in such notice,  Tenant's  right to
                 possession  shall  terminate,  and this Lease  shall  terminate
                 unless or before  such date all arrears of rental and all other
                 sums  payable  by  Tenant  under  this  Lease and all costs and
                 expenses  incurred by or on behalf of Landlord  hereunder shall
                 have been paid by Tenant  and all other  events of  default  of
                 this Lease by Tenant at the time existing shall have been fully
                 remedied to the  satisfaction  of  Landlord.  At any time after
                 such  termination,  Landlord  may  recover  possession  of  the
                 Premises  or any part  thereof  and expel and remove  therefrom
                 Tenant and any other person  occupying  the same, by any lawful
                 means,  and again  repossess  and enjoy  the  Premises  without
                 prejudice to any of the remedies  that  Landlord may have under
                 this Lease,  or at law or equity by reason of Tenant's  default
                 or of such termination.

                 (2) Continuation After Default. Even though an event of default
                 may have  occurred,  this Lease shall continue in effect for so
                 long  as  Landlord  does  not  terminate   Tenant's   right  to
                 possession  under Paragraph 26.B. (1) hereof,  and Landlord may
                 enforce all of Landlord's rights and remedies under this Lease,
                 including without  limitation,  the right to recover Rent as it
                 becomes due, and Landlord,  without  terminating this Lease may
                 exercise  all of the rights and  remedies  of a Landlord  under
                 Section  1951.4 of the Civil Code of the State of California or
                 any successor code section.  Acts of maintenance,  preservation
                 or  efforts  for lease the  Premises  or the  appointment  of a
                 receiver  upon  application  of Landlord to protect  Landlord's
                 interest  under this Lease shall not  constitute an election to
                 terminate Tenant's right to possession.

                 C. Damages After Default.  Should Landlord terminate this Lease
                 pursuant  to the  provisions  of  Paragraph  26.B  (1)  hereof,
                 Landlord  shall  have the  rights  and  remedies  of a Landlord
                 provided  by  Section  1951.2 of the Civil Code of the State of
                 California,  or successor code sections. Upon such termination,
                 in addition to any other rights and remedies to which  Landlord
                 may  be  entitled  under  applicable  law,  Landlord  shall  be
                 entitled to recover from  Tenant:  (1) the worth at the time of
                 award of the  unpaid  Rent and  other  amounts  which  had been
                 earned at the time of

                 termination,  (2) the worth at the time of award of the  amount
                 by which the unpaid  Rent which  would have been  earned  after
                 termination  until the time of award exceeds the amount of such
                 Rent  loss  that  Tenant  proves  could  have  been  reasonably
                 avoided;  (3) the  worth at the time of award of the  amount by
                 which the  unpaid  Rent for the  balance  of the Term after the
                 time of award  exceeds the amount of such Rent loss that Tenant
                 proves could be  reasonably  avoided;  and (4) any other amount
                 necessary  to   compensate   Landlord  or  all  the   detriment
                 proximately  caused by  Tenant's  failure to  perform  Tenant's
                 obligations  under this Lease or which,  in the ordinary course
                 of things,  would be likely to result therefrom.  The "worth at
                 the time of award" of the  amounts  referred  to in (1) and (2)
                 above  shall be  computed  by  discounting  such  amount at the
                 Federal  Discount  Rate  of the  Federal  Reserve  Bank  of San
                 Francisco at the time of the award.  If this Lease provides for
                 any periods during the Term during which Tenant is not required
                 to  pay  Base  Rent  or if  Tenant  otherwise  receives  a Rent
                 concession,  then upon the  occurrence  of an event of  default
                 Tenant  shall owe to Landlord the full amount of such Base Rent
                 or  value  of  such  Rent  concession,  plus  interest  at  the
                 Applicable  Interest Rate,  calculated  from the date that such
                 Base Rent or Rent concession would have been payable.

                 D. Late Charge. If any installment of Rent is not paid promptly
                 when due, and such failure is not cured prior to the expiration
                 of the  applicable  cure period  provided  herein,  such amount
                 shall bear  interest at the  Applicable  Interest Rate from the
                 date on which said payment shall be due until the date on which
                 Landlord  shall receive said payment. In addition, Tenant shall
                 pay  Landlord a late charge  equal to five  percent (5%) of the
                 delinquency,  to compensate Landlord for the loss of the use of
                 the amount not paid and the administrative  costs caused by the
                 delinquency,  the parties  agreeing that  Landlord's  damage by
                 virtue of such delinquencies  would be difficult to compute and
                 the amount  stated  herein  represents  a  reasonable  estimate
                 thereof. This  provision  shall not relieve  Tenant of Tenant's
                 obligation  to pay Rent at the time  and in the  manner  herein
                 specified.

                 E. Remedies Cumulative. All rights, privileges and elections or
                 remedies of the parties are cumulative and not alternative,  to
                 the extent  permitted by law and except as  otherwise  provided
                 herein.

                 the date such successor(s)-in-interest  became the owner of the
                 Building.                                                      
 
   RIGHT OF   29.    All  covenants  and  agreements  to be  performed by Tenant
LANDLORD TO      under  any of the terms of this  Lease  shall be  performed  by
    PERFORM      Tenant  at  Tenant's  sole cost and  expense  and  without  any
   TENANT'S      abatement  of  Rent.  If  Tenant  shall  fail to pay any sum of
  COVENANTS      money, other than Base Rent and Basic Operating Cost,  required
                 to be paid by Tenant  hereunder  or shall fail to  perform  any
                 other act on Tenant's part to be performed hereunder,  and such
                 failure shall  continue for five (5) days after notice  thereof
                 by Landlord, Landlord may, but shall not be obligated to do so,
                 and without waiving or releasing Tenant from any obligations of
                 Tenant,  make  any  such  payment  or  perform  any such act on
                 Tenant's  part to be made or  performed.  All sums,  so paid by

                 of such  payment by  Landlord  shall be payable to  Landlord on
                 demand,  and Tenant  covenants  to pay such sums,  and Landlord
                 shall  have,  in  addition  to any  other  right or  remedy  of

                 Tenant in the payment of Base Rent and Basic Operating Cost.   
              
WAIVER        30.    If either  Landlord or Tenant waives the performance of any
                 term,  covenant or  condition  contained  in this  Lease,  such
                 waiver  shall not be  deemed  to be a waiver of any  subsequent
                 breach of the same or any other  term,  covenant  or  condition
                 contained herein.  The acceptance of Rent by Landlord shall not
                 constitute  a waiver of any  preceding  breach by Tenant of any
                 term,  ccvenant  or  condition  of this  Lease,  regardless  of
                 Landlord's  knowledge  of such  preceding  breach  at the  time
                 Landlord accepted such Rent. Failure by Landlord to enforce any
                 of the terms,  covenants  or  conditions  of this Lease for any
                 length of time shall not be deemed to waive or to decrease  the
                 right of Landlord to insist thereafter upon strict  performance
                 by Tenant. Waiver by Landlord of any term, covenant or

                 a copy of such  notice  being  sent  via  commercial  overnight

                 judgment.

                 H.  Examination  of Lease.  Submission  of this Lease to Tenant
                 does not  constitute an option or offer to lease and this Lease
                 is not effective otherwise until execution and delivery by both
                 Landlord and Tenant.

                 I.  Accord and  Satisfaction.  No payment by Tenant of a lesser
                 amount than the Rent nor any endorsement on any check or letter
                 accompanying  any check or  payment  of Rent shall be deemed an
                 accord and  satisfaction  of full payment of Rent, and Landlord
                 may accept such payment without  prejudice to Landlord's  right
                 to  recover  the  balance  of  such  Rent  or to  pursue  other
                 remedies.

                 J.  Easements.  Landlord may grant easements on the Project and
                 dedicate  for  public  use  portions  of  the  Project  without
                 Tenant's  consent;  provided  that no such grant or  dedication
                 shall   substantially   interfere  with  Tenant's  use  of  the
                 Premises.   Upon  Landlord's  demand,   Tenant  shall  execute,
                 acknowledge  and  deliver to Landlord  documents,  instruments,

                 hereunder.

                 K. Drafting and  Determination.  The parties  acknowledge  that
                 this  Lease  has been  agreed  to by both  parties,  that  both
                 Landlord and Tenant have  consulted with attorneys with respect
                 to the  terms of this  Lease and that no  presumption  shall be
                 created against  Landlord  because Landlord drafted this Lease.
                 Except as otherwise  specifically set forth in this Lease, with
                 respect to any consent, determination or estimation of Landlord
                 required in this Lease or  requested  of  Landlord,  Landlord's
                 consent,   determination   or  estimation   shall  be  made  in
                 Landlord's good faith opinion,  whether objectively  reasonable
                 or unreasonable.

                 L.  Exhibits.  Exhibits  A and B  attached  hereto  are  hereby
                 incorporated herein by this reference.

                 M. No Light,  Air or View Easement.  Any diminution or shutting
                 off of light, air or view by any structure which may be erected
                 on lands  adjacent to or in the vicinity of the Building  shall
                 in no  way  affect  this  Lease  or  impose  any  liability  on
                 Landlord.

                 N. No Third  Party  Benefit.  This Lease is a contract  between
                 Landlord  and Tenant and  nothing  herein is intended to create
                 any third party benefit.

                 O. Security,  Release and Indemnity.  Tenant  acknowledges  and
                 agrees  that,  while  Landlord may elect to patrol the Project,
                 Landlord is not providing any security services with respect to
                 the  Premises and that  Landlord  shall not be liable to Tenant
                 for, and Tenant waives any claim against  Landlord with respect
                 to, any loss by theft or any other damage to person or property
                 suffered  or  incurred  by  Tenant,   Tenant's   employees  and
                 invitees,  including but not limited to, in connection with any
                 unauthorized  entry into the  Premises  or any other  breach of
                 security with respect to the Premises.

                 Tenant shall be responsible  for provisions of security for its
                 premises.  Tenant shall  defend,  indemnify  and hold  Landlord
                 harmless  with respect to the  Premises and any claims  arising
                 from or related to a purported breach of security or failure to
                 provide security.

                 to  a  one-time  tenant  improvement   allowance  (the  "Tenant
                 Improvement  Allowance") in the amount of five dollars  ($5.00)
                 for each of the useable  square feet of the Premises  listed in
                 the Basic Lease  Information  for the direct and indirect costs
                 relating to the initial designing, procuring,  constructing and
                 installing  of  Tenant's  improvements  which  are  permanently

                 Landlord's  review and approval of Tenant's proposed space plan
                 for the  Premises,  Tenant  will use its  architect  for design

                 tenant improvement work. Landlord reserves the right to approve
                 Tenant's   construction    management   company   and   general
                 contractor.  In no event shall  Landlord be  obligated  to make
                 disbursements  in a  total  amount  which  exceeds  the  Tenant
                 Improvement Allowance.

                     B. Disbursement of the Tenant Improvement Allowance. Except
                 as otherwise  set forth in any Tenant Work  Letter,  the Tenant
                 Improvement  Allowance  shall be disbursed by Landlord (each of
                 which  disbursements  shall  be  made  pursuant  to  Landlord's
                 disbursement  process) for costs related to the construction of
                 the Tenant  Improvements  and for the following items and costs
                 (collectively,  the "Tenant Improvement  Allowance Items"): (i)
                 payment of the fees of  Tenant's  architect  and/or  engineers;
                 (ii) the cost of construction of the Tenant  Improvements (iii)
                 the cost of  procuring  and  installing  fixtures  in or on the
                 Premises;  and  (iv) the cost of  other  items  related  to the
                 design  and   construction   of  the  Tenant   Improvements  as
                 designated by Tenant.

              41.    Landlord's  Obligations Prior to Occupancy.  Landlord shall
                 be responsible, at its sole cost and expense, prior to Tenant's

                 fixtures,  and finishes in compliance with the  requirements of
                 the Americans With  Disabilities Act of 1990; (ii) all building
                 systems,  including existing electrical,  mechanical,  HVAC and

                 to deferred maintenance or in need of immediate replacement. In
                 addition  Landlord,  prior to Tenant's  occupancy,  shal supply
                 Tenant with any existing  floor plans for the Premises known as

                 under the same terms and conditions prior to then expiration of

                 beginning monthly rental rate, for the option period,  shall be
                 at rate  equal  to the  then  prevailing  fair  market  rate of
                 comparable  R&D  buildings  in the market.  Tenant's  desire to
                 exercise the option must be given to Landlord,  in writing, not
                 less than one-hundred eighty (180) days prior to the expiration
                 of the term or this option shall terminate and be of no further
                 effect.

              44.    Expansion  Space.  Landlord  will use its best  efforts  to
                 inform Tenant of any and all available  contiguous space to the

ARTICLE 2: SUBLEASE PREMISES.

2.1 Sublease.  Sublessor  hereby  subleases to Sublessee  and  Sublessee  hereby
subleases from  Sublessor for the Sublease Term  (hereinafter  defined),  at the
Rent  (hereinafter  defined) and upon the terms and conditions  hereinafter  set
forth, the Sublease  Premises,  and all common areas related thereto.  Sublessee
acknowledges  that the leasable  area of the  Sublease  Premises as specified in
Article 1 is an estimate and that  Sublessor does not warrant the exact leasable
area of the Sublease  Premises.  By taking possession of the Sublease  Premises,
Sublessee  accepts the leasable area of the Sublease  Premises as that specified
in Article 1.

2.2  Condition of the Sublease  Premises.  Sublessor  shall deliver the Sublease
Premises  to  Sublessee  with all  building  systems  (i.e.,  HVAC,  electrical,
plumbing and roof) in good  operating  condition,  and warrants the same for the
first thirty (30) days of the Sublease Term. Sublessee  acknowledges that except
as expressly  stated in this  Sublease,  (i)  Sublessor  makes no  warranties or
representations  regarding the physical condition of the Sublease Premises; (ii)
Sublessee has had an opportunity to inspect the Sublease Premises, including the
roof and structural components of the building; the electrical,  plumbing, HVAC,
and other building systems serving the Sublease Premises;  and the environmental
condition of the Sublease Premises and related common areas; and to hire experts
to conduct such  inspections on its behalf;  and (iii)  Sublessee is leasing the
Sublease Premises based on its own inspection of the Sublease Premises and those
of its  agents,  and is  not  relying  on  any  statements,  representations  or
warranties  of  Sublessor  regarding  the  physical  condition  of the  Sublease
Premises.  In  addition,  Sublessor  shall  pass on to  Sublessee  any  existing
construction warranties that are available.

2.3 Personal Property.  Sublessee  acknowledges that the Sublease Premises shall
not  include  any of the  fixtures,  equipment,  cabling,  furniture,  or  other
personal property  belonging to Sublessor,  except as specifically  agreed to by
the parties in the Furniture  Rental  Agreement dated as of October 1, 1998. The
parties  acknowledge  that the Furniture Rental  Agreement  represents  material
consideration for each party's entering into this Sublease.

2.4  Alterations  to  Premises.   Sublessee  shall  not  make  any  alterations,
additions,  or improvements to the Sublease  Premises  without the prior written
consent of Sublessor;  provided, however, that Sublessee may make non-structural
alterations  to the Sublease  Premises  costing less than five thousand  dollars
($5,000.00) in accordance with and subject to Paragraph 12 of the Master Lease.

ARTICLE 3: TERMS OF THE MASTER LEASE.

3.1 Sublease  Subordinate.  This Sublease  is subordinate  and subject to all of
the terms and conditions of the Master Lease. If the Master Lease terminates for
any reason  whatsoever,  this Sublease  shall  terminate  concurrently,  and the
parties hereto shall be relieved of any liability thereafter accruing under this
Sublease,  except for the  liabilities of the parties which by the terms of this
Sublease survive the expiration or earlier termination of this Sublease.

3.2 Sublessee's  Obligations.  Sublessee hereby expressly  assumes and agrees to
perform and  discharge,  as and when  required by the Master  Lease,  all debts,
duties and  obligations to be paid,  performed or discharged by Sublessor  under
the terms,  covenants  and  conditions  of the  Master  Lease from and after the
Commencement Date, except as specifically set forth in this Sublease.  Sublessee
shall not commit or suffer at any time any act or  omission  that would  violate
any provision of the Master Lease.

3.3  Sublessor's  Obligations.  So long as Sublessee does not default under this
Sublease,  Sublessor  shall not commit any act or omission  during the  Sublease
Term which would lead to the  termination  of the Master Lease by Master Lessor.
Notwithstanding  the  foregoing,  if  Sublessee  fails to comply with any of its
obligations under this Sublease  (including  without  limitation the obligations
assumed by  Sublessee  under the Master  Lease),  and does not cure such failure
within  the  applicable  cure  period  (or if no cure  period  is  specified  in
either this  Sublease  or the  Master  Lease,  then within  five (5) days  after
receiving  written  notice  of  such  failure),  then  Sublessor  shall  have no
obligation to Sublessee to maintain the Master Lease for Sublessee's benefit.

                                     Page 3

<PAGE>


3.4 Master Lessor's Obligations. Sublessor shall not be responsible to Sublessee
for furnishing any service, maintenance or repairs to the Sublease Premises that
are the  obligation  of the  Master  Lessor  under the  Master  Lease,  it being
understood  that Sublessee shall look solely to Master Lessor for performance of
any such service,  maintenance or repairs.  However, if Master Lessor shall fail
to perform its obligations  under the Master Lease,  Sublessor,  upon receipt of
written notice from  Sublessee,  shall use  commercially  reasonable  efforts to
attempt to enforce the  obligations  of Master  Lessor  under the Master  Lease;
provided,  however,  that Sublessor  shall not be required to incur any costs or
expenses in connection  therewith unless Sublessee agrees to reimburse Sublessor
for any such costs and expenses as Additional Rent hereunder.

3.5 Sublessor's Rights and Remedies.  In addition to all the rights and remedies
provided to  Sublessor at law, in equity,  or under the terms of this  Sublease,
(a) in the event of any breach by Sublessee of any of its obligations under this
Sublease,  Sublessor  shall have all of the rights and remedies  with respect to
such  breach  which are  available  to Master  Lessor in the event of any breach
under the Master  Lease;  and (b) as a further  remedy,  if  Sublessee  fails to
perform any act on its part to be performed  pursuant to the requirements of the
Master Lease or as otherwise  required by this  Sublease,  within any applicable
grace periods  provided  herein,  then Sublessor may, but shall not be obligated
to,  fulfill such  obligations  of  Sublessee,  including  entering the Sublease
Premises  to  perform  any such  act,  and all costs and  expenses  incurred  by
Sublessor  in doing so shall be deemed  Additional  Rent payable by Sublessee to
Sublessor upon demand.

3.6  Sublessee's  Right to Cure.  In the event of  default by  Sublessor  of any
obligation  under  the  Master  Lease,  subject  to Master  Lessor's  agreement,
Sublessee  shall have the right and  opportunity to cure such default within the
applicable cure period provided in the Master Lease, or within five (5) business
days after  receipt of Master  Lessor's  notice of such  default,  whichever  is
later.  In the event that Sublessee  cures such a default by Sublessor under the
Master Lease,  Sublessee  shall have the right to offset the amount paid to cure
such default and other related  costs,  including  reasonable  attorneys'  fees,
against any amounts owed by Sublessee under this Sublease.

3.7  Authorization to Direct Sublease  Payments.  Sublessor hereby  acknowledges
that  Sublessor's  failure to pay the rent and other sums owing by  Sublessor to
Master  Lessor  under the Master Lease will cause  Sublessee  to incur  damages,
costs and expenses not  contemplated by the Sublease,  especially in those cases
where Sublessee has paid sums to Sublessor  hereunder which  correspond in whole
or in part to the amounts  owing by Sublessor to Master  Lessor under the Master
Lease.  Accordingly,  Sublessee  shall  have the right to pay all rent and other
sums owing by Sublessee to  Sublessor  hereunder  for those items which also are
owed by  Sublessor to Master  Lessor  under the Master Lease  directly to Master
Lessor on the following terms and conditions:

          (a) Either (i) Sublessee reasonably believes that Sublessor has failed
to make any payment  required to be made by Sublessor to Master Lessor under the
Master Lease and Sublessor fails to provide adequate proof of payment within two
(2) business days after  Sublessee's  written demand  requesting  such proof; or
(ii) Sublessee reasonably believes that Sublessor shall fail to make any payment
required to be made by  Sublessor  to Master  Lessor  under the Master Lease and
Sublessor fails to provide adequate  assurance of future  performance within two
(2) business days after Sublessee's written demand requesting such assurance.

          (b) Sublessee shall not prepay any amounts owing by Sublessor  without
the consent of Sublessor.

          (c) Sublessee shall provide to Sublessor concurrently with any payment
to Master Lessor reasonable evidence of such payment.

          (d) If  Sublessor  notifies  Sublessee  that it  disputes  any  amount
demanded by Master Lessor,  Sublessee  shall not make any such payment to Master
Lessor unless  Master Lessor has provided a three-day  notice to pay such amount
or forfeit the Master Lease.

          Any sums paid  directly by  Sublessee to Master  Lessor in  accordance
with this  paragraph and other costs  reasonably  incurred as a  consequence  of
Sublessor's failure to pay required sums to Master Lessor,  including attorneys'
fees,  shall be credited  toward the amounts  payable by  Sublessee to Sublessor
under the Sublease.

ARTICLE 4: SUBLEASE TERM.

4.1  Commencement and Termination  Dates.  The term of this Sublease  ("Sublease
Term") shall be for the period of time commencing on the scheduled  commencement
date  described  in  Article  1 (the  "Commencement  Date")  and  ending  on the
termination  date  described in Article I or on such earlier date of termination
as provided herein (the "Termination Date").

4.2 Delay in Commencement. If for any reason possession of the Sublease Premises
has not been  delivered to Sublessee by the scheduled  Commencement  Date or any
other date,  Sublessor  shall not be liable to  Sublessee or any other person or
entity for any loss or damage resulting  therefrom.  In the event of such delay,
the Commencement  Date and the Rental  Commencement  Date shall be delayed until
possession  of  the  Sublease  Premises  is  delivered  to  Sublessee,  but  the
Termination  Date  shall not be  extended.  If  Sublessor  is unable to  deliver
possession  of the Sublease  Premises to Sublessee  within sixty (60) days after
the scheduled  Commencement  Date, then Sublessee may terminate this Sublease by
giving  written notice to Sublessor at any time after that date, and the parties
shall  have no  further  liability  thereafter  accruing  under  this  Sublease;
provided, however, that if Sublessor tenders possession to Sublessee within five
(5) days after receipt of Sublessee's  notice of termination,  such notice shall
be void.

4.3 Early  Occupancy.  If  Sublessor  permits  Sublessee  to occupy the Sublease
Premises prior to the Commencement  Date, such occupancy shall be subject to all
of the  provisions of this  Sublease,  including the payment of Minimum  Monthly
Rent. Early occupancy of the Sublease Premises shall not advance the Termination
Date.  Sublessee  shall,  prior to entering  the Sublease  Premises,  deliver to
Sublessor   certificates  of  insurance  evidencing  the  policies  required  of
Sublessee under this Sublease.

ARTICLE 5: RENT AND ADDITIONAL EXPENSES.

5.1 Payment of Rent. All monies  payable by Sublessee  under this Sublease shall
constitute  "Rent." All Rent shall be paid in lawful money of the United States,
without any  deduction  or offset,  to  Sublessor  at the  address of  Sublessor
specified  in  Article 1 or such  other  place as  Sublessor  may  designate  in
writing.  No  payment  by  Sublessee  of a lesser  amount  than the Rent  herein
stipulated  shall  be  deemed  to be  other  than  on  account  of the  earliest
stipulated  Rent,  nor shall any  endorsement  or  statement on any check or any
letter  accompanying  any check or  payment  of Rent be  deemed  an  accord  and
satisfaction,  and Sublessor may accept such check or payment without  prejudice
to its right to recover the balance of such Rent or to pursue any other  remedy.
Rent for any partial  calendar  months at the  beginning  or end of the Sublease
Term or by early occupancy of the Sublease Premises shall be prorated based on a
thirty (30) day month.

5.2 Minimum Monthly Rent.  Sublessee shall pay to Sublessor the sum set forth in
Article 1 hereof as Minimum  Monthly Rent, in advance,  on the first day of each
calendar  month   throughout  the  Sublease  Term,   commencing  on  the  Rental
Commencement Date.

5.3 Additional Rent.  In addition to Minimum  Monthly  Rent,  commencing  on the
Commencement  Date (or, if earlier,  upon occupancy of the Sublease  Premises by
Sublessee),  Sublessee shall pay to Sublessor, on the first day of each calendar
month,  as  "Additional  Rent,"  estimated  payments for real property taxes and
assessments,  maintenance,  repair, management,  insurance,  utilities and other
charges  attributable to and/or accruing  against the Sublease  Premises and the
related  common areas for the Sublease  Term,  in such amounts as are payable by
Sublessor under the Master Lease;  provided,  however, that for the term of this
Sublease  Additional  Rent will not  exceed  $.20/rsf  (i.e.,  $3,279.40/month),
exclusive of any increases in real property taxes and  assessments and insurance
premiums  above the cost of real property  taxes and  assessments  and insurance
premiums for the period from July 1998 through June 1999,  which increases shall
be  paid  by  Sublessee.  However,  notwithstanding  anything  to  the  contrary
contained  in  this  Sublease,  Sublessee  shall  not be  required  to  pay  any
additional  rent or perform any obligation  that is (i) fairly  allocable to any
period of time prior to the Commencement  Date or following the Termination Date
or earlier  expiration  of the Sublease  Term;  or (ii) payable as a result of a
default by Sublessor of any of its  obligations  under the Master Lease  (unless
such default is a result of Sublessee's default under this Sublease).

                                     Page 5

<PAGE>


5.4 Prepaid Rent.  Concurrently  with  Sublessee's  execution of this  Sublease,
Sublessee shall pay to Sublessor the sum specified in Article 1 as Prepaid Rent,
which  shall  be  applied  to the  installments  of  Minimum  Monthly  Rent  and
Additional Rent first coming due under this Sublease.

5.5 Late Charge.  If Sublessee  fails to pay any Rent when due  hereunder,  then
Sublessee  shall pay  Sublessor a late charge  equal to six percent (6%) of such
delinquent amount as liquidated  damages for Sublessee's  failure to make timely
payment.  Any  notice  given by  Sublessor  pursuant  to any  statute  governing
unlawful  detainer  actions  shall be deemed to be concurrent  with,  and not in
addition to, the notice required herein.  This provision for a late charge shall
not be  deemed  to grant  Sublessee  a grace  period  or  extension  of time for
performance.  If any Rent is not paid  promptly  when due,  then, in addition to
such late charge,  Sublessee  shall pay to Sublessor  interest on the delinquent
amount from the date on which said payment is due until paid, at the rate of ten
percent (10%) per annum or the maximum rate permitted by law, whichever is less.

ARTICLE 6: SECURITY  DEPOSIT.  Upon execution of this Sublease,  Sublessee shall
provide  to  Sublessor  an  irrevocable  letter  of credit  ("LOC")  in favor of
Sublessor,  with a financial institution reasonably acceptable to Sublessor, and
in substantially  the form attached hereto as Exhibit B, in the amount specified
in Article 1 hereof as a "Security  Deposit."  Landlord  may draw on such LOC in
whole  or in  part,  in  lieu  of a  cash  Security  Deposit,  as  security  for
Sublessee's faithful performance under this Sublease.  If Sublessee fails to pay
any Rent as and when due under this  Sublease or otherwise  fails to perform its
obligations hereunder,  then after giving Sublessee five (5) days written notice
(referenced  in Exhibit B as a Letter of Intent to Draw),  Sublessor may, at its
option and without  prejudice to any other remedy which Sublessor may have, draw
on the LOC and apply,  use or retain all or any portion of the Security  Deposit
toward the payment of  delinquent  Rent or for any loss or damage  sustained  by
Sublessor due to such failure by Sublessee.

ARTICLE 7: USE.

7.1 Use of the Sublease  Premises.  Sublessee  shall use the  Sublease  Premises
solely for the purposes  specified in Article 1 in strict  conformance  with the
applicable   requirements  of  the  Master  Lease,  and  for  no  other  purpose
whatsoever,  unless  Sublessee shall first have obtained the written approval of
Sublessor  (which approval shall not be unreasonably  withheld),  Master Lessor,
and any and all applicable governmental agencies.

7.2 Suitability. Sublessee acknowledges that, except as may be explicitly stated
in this  Sublease,  neither  Sublessor  nor any agent of Sublessor  has made any
representation or warranty with respect to the Sublease Premises,  the permitted
uses that can be made of the  Sublease  Premises  under  existing  laws,  or the
suitability of the Sublease  Premises for the conduct of  Sublessee's  business,
nor  has  Sublessor  agreed  to  undertake  any   modification,   alteration  or
improvement to the Sublease Premises.

7.3 Hazardous Materials.

         7.3.1 Definitions.  As used in this Sublease, the following terms shall
have the meanings set forth below:

         (a) "Hazardous  Material" shall mean any hazardous or toxic  substance,
material or waste which is or becomes regulated by any state,  federal, or local
government  authority,  including without  limitation all of those materials and
substances  designated  as  hazardous or toxic by the  Environmental  Protection
Agency,  the  Department  of  Labor,  the  Department  of  Transportation,   the
Department of  Agriculture,  the  Department of Health  Services or the Food and
Drug  Agency.  Without  limiting  the  generality  of the  foregoing,  the  term
"Hazardous  Material" shall include (i) any substance,  product,  waste or other
material of any nature  whatsoever  which may give rise to  liability  under any
statutory or common law theory based on negligence,  trespass, intentional tort,
nuisance  or strict  liability  or under any  reported  decisions  of a state or
federal court;  (ii)  gasoline,  diesel fuel, or other  petroleum  hydrocarbons;
(iii) polychlorinated  biphenyls;  (iv) asbestos containing materials;  (v) urea
formaldehyde foam insulation; and (vi) radon gas.

         (b) "Hazardous  Material Law" shall mean any applicable  statute,  law,

<PAGE>


of any governmental body or agency which regulates the use, storage, generation,
discharge,  treatment,  transportation,  release,  or disposal of any  Hazardous
Material.

         (c) "Hazardous  Material Use" shall mean and include any use,  storage,
generation,  treatment, or transportation of any Hazardous Material within, from
or to,  on or  about,  or  upon  the  Sublease  Premises  or any  other  land or
improvements in the vicinity of the Sublease Premises.

         (d) "Hazardous  Material Release" shall mean and include any discharge,
release,  emission or disposal of any Hazardous Material within,  from or to, on
or about, or upon the Sublease Premises or any other land or improvements in the
vicinity of the Sublease Premises.

         (e)  "Agents"  shall mean  agents,  employees,  invitees,  contractors,
sublessees, licensees, successors and assigns.

         7.3.2  Sublessor's  Representation.  Except as previously  disclosed to
Sublessee, to Sublessor's actual current knowledge, (i) no Hazardous Material is
present  on or  about  the  Sublease  Premises  or the  soil,  surface  water or
groundwater  thereof;  (ii) no underground storage tanks are present on or about
the Sublease  Premises;  and (iii) no action,  proceeding or claim is pending or
threatened  regarding the Sublease Premises concerning any Hazardous Material or
pursuant to any Hazardous Material Law.

         7.3.3  Use  Restriction.  Sublessee  shall  not  cause  or  permit  any
Hazardous  Material Use without the prior  written  consent of Master Lessor and
Sublessor,  and in any event  Sublessee  shall not cause or permit any Hazardous
Material  Release.  Without  limiting the generality of the  foregoing,  (a) any
Hazardous  Material Use by Sublessee or Sublessee's Agents shall strictly comply
with  all  applicable  Hazardous  Material  Laws,  and (b) in the  event  of any
Hazardous Material Release by Sublessee or Sublessee's Agents, Sublessee, at its
expense,  shall  promptly  take all  actions  necessary  to return the  Sublease
Premises to the condition existing prior to such Hazardous Material Release.

         7.3.4 Exclusion from Liability.  Under no circumstances shall Sublessee
be liable for, and Sublessor shall indemnify, defend and hold harmless Sublessee
and  Sublessee's  Agents from and  against,  all costs and  expenses  (including
attorneys'  and  consultants'  fees)  related to or in  connection  with (i) the
investigation,  reporting,  removal and remediation of any Hazardous Material on
or about the Sublease Premises,  or (ii) the violation of any Hazardous Material
Law,  except to the extent that any of the  foregoing  results  from a Hazardous
Material Use or a Hazardous Material Release by Sublessee or Sublessee's Agents.

ARTICLE 8: SURRENDER.

         8.1 Condition of the Sublease Premises.  Upon the expiration or earlier
termination of this Sublease,  Sublessee shall  surrender the Sublease  Premises
broom clean and in the same  condition and repair as the Sublease  Premises were
delivered to Sublessee on the  Commencement  Date,  excepting only ordinary wear
and tear and damage by fire, earthquake,  act of God or the elements.  Sublessee
agrees to repair any damage to the Sublease  Premises,  or the building of which
the  Sublease  Premises  are a part,  caused by or related to the removal of any
articles of personal property, business or trade fixtures, machinery, equipment,
cabinetwork,  signs, furniture,  movable partitions or permanent improvements or
additions which  Sublessor  allows or requires  Sublessee to remove,  including,
without  limitation,  repairing the floor and patching and/or painting the walls
where required by Sublessor to the reasonable  satisfaction of Sublessor  and/or
Master  Lessor,  all at  Sublessee's  sole  cost and  expense.  Sublessee  shall
indemnify  Sublessor  against  any  loss or  liability  resulting  from delay by
Sublessee  in  so  surrendering  the  Sublease  Premises,   including,   without
limitation,  any claims made by the Master Lessor and/or any  succeeding  tenant
founded on such delay. Such indemnity obligation shall survive the expiration or
earlier termination of this Sublease.

         8.2 Sublessor's  Right to Access.  Unless  otherwise agreed pursuant to
the Furniture Rental Agreement  referenced  above, in the thirty (30) days prior
to the  expiration  of this  Sublease,  or such  shorter  time as is  reasonably
necessary,  Sublessor shall have the right, upon at least twenty-four (24) hours
prior notice, to enter the Sublease Premises during non-business hours to remove
personal property belonging to Sublessor, if any (including without

                                     Page 7

<PAGE>


limitation any business or trade fixtures,  machinery,  equipment,  cabinetwork,
signs,  furniture,  and movable partitions owned by Sublessor and located within
the Sublease Premises) and to remove any improvements or additions, if any, that
Sublessor is required to remove  prior to surrender of the Premises  pursuant to
the Master Lease (not including those items to be removed by Sublessee  pursuant
to Article 8.1 of this  Sublease).  Any work performed by Sublessor  pursuant to
the terms of the  preceding  sentence  shall be done in a  reasonable  manner to
minimize the amount of  inconvenience  and  interference  to Sublessee's use and
occupancy of the Sublease Premises;  provided,  however,  Sublessor shall not be
liable  to  Sublessee  for any such  inconvenience  or  interference  caused  by
Sublessor's reasonable exercise of its rights pursuant to this provision.

ARTICLE 9:  CONSENT.  Whenever  the  consent  or  approval  of Master  Lessor is
required  pursuant to the terms of the Master  Lease,  for the  purposes of this
Sublease,  Sublessee,  in each such  instance,  shall be  required to obtain the
written  consent or  approval  of both Master  Lessor and  Sublessor.  If Master
Lessor  refuses to grant its consent or  approval,  Sublessor  may  withhold its
consent or approval and Sublessee  agrees that such action by Sublessor shall be
deemed reasonable.

ARTICLE  10:  INSURANCE.  All  insurance  policies  required  to be  carried  by
Sublessor  under the Master Lease shall be maintained  by Sublessee  pursuant to
the terms of the Master Lease,  and shall name  Sublessor and Master Lessor (and
such other  lenders,  persons,  firms,  or  corporations  as are  designated  by
Sublessor or Master Lessor) as additional insureds by endorsement.  All policies
shall be written as primary  policies  with  respect to the  interests of Master
Lessor and Sublessor and such other  additional  insureds and shall provide that
any  insurance  carried by Master  Lessor or Sublessor or such other  additional
insureds is excess and not contributing  insurance with respect to the insurance
required  hereunder.  All  policies  shall also  contain  "cross  liability"  or
"severability  of interest"  provisions and shall insure the  performance of the
indemnity  set forth in Article 14 of this  Sublease.  Sub lessee shall  provide
Master  Lessor  and  Sublessor  with  copies or  certificates  of all  policies,
including in each instance an endorsement  providing  that such insurance  shall
not be cancelled or amended  except after thirty (30) days prior written  notice
to  Master  Lessor  and  Sublessor.  All  deductibles,  if any,  under  any such
insurance  policies  shall  be  subject  to the  prior  reasonable  approval  of
Sublessor,  and all certificates  delivered to Master Lessor and Sublessor shall
specify the limits of the policy and all deductibles thereunder.

ARTICLE 11: NOTICES.

11.1 Notice Requirements.   All notices, demands,  consents, and approvals which
may or are required to be given by either party to the other under this Sublease
shall be in writing and may be given by (i) personal  delivery,  (ii)  overnight
courier such as Federal Express,  or (iii) United States registered or certified
mail  addressed  as shown in Article 1.  Any notice or demand so given  shall be
deemed to be  delivered  or made on (i) the date  personal  service is effected,
(ii) the next  business  day if sent by overnight  courier,  or (iii) the second
business day after the same is deposited in the United States Mail as registered
or certified and addressed as above provided with postage thereon fully prepaid.
Either party hereto may change its address at any time by giving  written notice
of such  change to the other  party in the manner  provided  herein at least ten
(10) calendar days prior to the date such change is desired to be effective.

11.2 Notices from Master  Lessor.  Each party shall provide to the other party a
copy of any notice or demand  received from or delivered to Master Lessor within
twenty four (24) hours of receiving or delivering such notice or demand.

ARTICLE 12:  DAMAGE,  DESTRUCTION,  CONDEMNATION.  To the extent that the Master
Lease  gives  Sublessor  any rights  following  the  occurrence  of any  damage,
destruction or  condemnation to terminate the Master Lease, to repair or restore
the Sublease Premises,  to contribute toward such repair or restoration costs to
avoid termination,  to obtain and utilize insurance or condemnation  proceeds to
repair or restore the  Sublease  Premises,  or any similar  rights,  such rights
shall be  reserved  to and  exercisable  solely  by  Sublessor,  in its sole and
absolute  discretion,  and not by  Sublessee.  The exercise of any such right by
Sublessor shall under no circumstances constitute a default or breach under this
Sublease or subject Sublessor to any liability therefor.

ARTICLE  13:  INSPECTION  OF  THE  SUBLEASE  PREMISES.  Sublessee  shall  permit
Sublessor and its agents to enter the Sublease  Premises at any reasonable  time
for the purpose of inspecting the same or posting a notice of  nonresponsibility
for alterations, additions or repairs, provided that Sublessor provides at least
twenty-four (24) hours prior notice (except in the case of emergency).

ARTICLE 14: INDEMNITY; EXEMPTION OF SUBLESSOR FROM LIABILITY.

14.1  Sublessee  Indemnity.  Sublessee  shall  indemnify,  defend (with  counsel
reasonably  satisfactory to Sublessor),  protect and hold harmless Sublessor and
its  agents,  employees,   contractors,   stockholders,   officers,   directors,
successors  and assigns from and against any and all claims,  demands,  actions,
suits, proceedings, liabilities, obligations, losses, damages, judgments, costs,
penalties,  fines,  and  expenses,  including,  but not limited to,  attorneys',
consultants' and expert witness fees  (collectively,  "Claims")  arising out of,
resulting from, or related to (i) any injury or death to any person or injury or
damage to property  caused by, arising out of, or involving (A)  Sublessee's use
of the Sublease Premises,  the conduct of Sublessee's  business therein,  or any
activity, work or thing done, permitted or suffered by Sublessee in or about the
Sublease  Premises  or the  common  areas,  (B) a  breach  by  Sublessee  in the
performance  in a timely  manner of any  obligation of Sublessee to be performed
under this Sublease,  or (C) the negligence or intentional  acts of Sublessee or
Sublessee's Agents, and/or (ii) any Hazardous Material Use or Hazardous Material
Release by Sublessee or Sublessee's Agents;  provided,  however,  that Sublessor
shall not be  indemnified  to the  extent  any  Claims  are  caused by the gross
negligence  or willful  misconduct  of Sublessor  or  Sublessor's  Agents.  This
indemnity shall survive the expiration or earlier termination of this Sublease.

14.2 Sublessee  Waiver.  Sublessee,  as a material part of the  consideration to
Sublessor,  hereby  assumes  all risk of damage to property or injury to persons
in, upon or about the Sublease  Premises  arising  from any cause and  Sublessee
hereby waives all claims in respect  thereof  against  Sublessor,  except to the
extent damage or injury is caused by the gross negligence or willful  misconduct
of Sublessor or Sublessor's Agents;  provided,  however,  that in no event shall
Sublessor  be  liable  for  any  loss  of  profits  or  any  special,  indirect,
incidental,  consequential or punitive damages, however caused and on any theory
of liability. This waiver shall survive the expiration or earlier termination of
this Sublease.

14.3 Mutual Waiver of  Subrogation.  The parties  hereto  release each other and
their  respective  Agents from all  liability for damage to any property that is
caused by or results from a risk that is actually  insured against or that would
normally  be covered by  the  standard  form of "all risk"  property  insurance,
without  regard  to the  negligence  or  willful  misconduct  of the  entity  so
released.  Each party shall use its best efforts to cause each insurance  policy
it obtains to provide that the insurer  thereunder  waives all right of recovery
by way of subrogation as required  herein in connection with any property damage
covered by the policy.

ARTICLE 15:  ASSIGNMENT AND  SUBLETTING.  Sublessee  shall not voluntarily or by
operation  of law  assign  this  Sublease  or enter into  license or  concession
agreement,  sublet  all or any  part  of the  Sublease  Premises,  or  otherwise
transfer,  mortgage,  pledge,  hypothecate  or  encumber  all  or  any  part  of
Sublessee's  interest in this  Sublease or in the Sublease  Premises or any part
thereof,  without the prior written  consent of Master  Lessor  (pursuant to the
terms  of  the  Master  Lease)  and  Sublessor   (whose  consent  shall  not  be
unreasonably withheld or conditioned). Any attempt to do so without such consent
being first had and obtained shall be wholly void and shall constitute a default
by Sublessee under this Sublease.  However, Sublessor hereby agrees that it will
consent to any  subletting  of the Sublease  Premises or any  assignment of this
Sublease to (i) a corporation controlling, controlled by or under common control
with Sublessee; (ii) a corporation related to Sublessee by merger, consolidation
or non-bankruptcy  reorganization;  or (iii) a purchaser of substantially all of
Sublessee's  assets;  provided  that (a)  Sublessee  first  obtains  the written
consent of Master Lessor to such  transaction;  and (b) any and all compensation
realized by Sublessee  under any such  sublease or  assignment  in excess of the
Rent payable  under this Sublease  shall belong to Sublessor,  to be included as
part of  "bonus  rent" as  described  in  Paragraph  21.B of the  Master  Lease.
Notwithstanding any assignment or subletting, Sublessee shall not be relieved of
its obligations  hereunder,  and a consent to one assignment or subletting shall
not  constitute a consent to any other  assignment  or subletting or a waiver of
the provisions of this section.

                                     Page 9

ARTICLE  16:  DELIVERY OF  DOCUMENTS.  Sublessee  shall  execute and deliver any
document or other instrument  required by Master Lessor or Sublessor pursuant to
the Master Lease  within five (5) days  following  receipt of a written  request
from Master Lessor or  Sublessor.  Failure to comply with this  provision  shall
constitute a default by Sublessee under this Sublease.

ARTICLE 17: HOLDING OVER.

17.1 Without Consent.  Any holding over by Sublessee after the Termination Date,
without the prior  written  consent of Master  Lessor and  Sublessor,  shall not
constitute a renewal or extension of this Sublease or give  Sublessee any rights
in or to the Sublease Premises. In the event of any such non-permissive  holding
over,  Sublessor  and Master  Lessor may seek any and all remedies  available to
Sublessor  and/or  Master Lessor at law or in equity,  and  Sublessee  shall pay
Sublessor upon demand, (i) all damages,  costs,  expenses,  and fees incurred or
suffered by  Sublessor  under the Master  Lease as a result of such  holdover by
Sublessee,  including  without  limitation  any  increase  in rentals  resulting
therefrom,  and (ii) all  attorneys'  fees and  out-of-pocket  costs incurred by
Sublessor arising out of or in connection with such holdover.

17.2 With Consent.  Any holding over by Sublessee  after the  Termination  Date,
with the  prior  written  consent  of  Master  Lessor  and  Sublessor,  shall be
construed  as a  month-to-month  tenancy  on the same  terms and  conditions  as
specified  in this  Sublease,  except that the Minimum  Monthly Rent during such
tenancy  shall be  increased  to an amount  equal to One Hundred  Fifty  Percent
(150%) of the most recent applicable Minimum Monthly Rent amount.

ARTICLE 18:  OPTIONS.  Any right of Sublessor to extend or renew the term of the
Master  Lease or to expand  the  Premises  (if any),  shall be  reserved  to and
exercisable solely by Sublessor,  in its sole discretion,  and not by Sublessee.
Sublessor  agrees to exercise  such  rights to extend or renew the Master  Lease
only to the extent necessary to fulfill its obligations under this Sublease.

         (a) The Master  Lease is in full  force and  effect,  and there  exists
under the Master Lease no default or event of default by either Master Lessor or
Sublessor,  nor has there occurred any event which, with the giving of notice or
passage of time or both, could constitute such a default or event of default.

         (b) There are no pending or threatened  actions,  suits or  proceedings
before any court or  administrative  agency against  Sublessor or against Master
Lessor or third  parties which could,  in the  aggregate,  adversely  affect the
Sublease Premises or any part thereof or the ability of Master Lessor to perform
its  obligations  under  the  Master  Lease  or  of  Sublessor  to  perform  its
obligations  under the  Sublease,  and Sublessor is not aware of any facts which
might result in any such actions, suits or proceedings.

         (c)  There  is  no  pending  or  threatened   condemnation  or  similar
proceedings  affecting the Premises or any portion thereof, and Sublessor has no
knowledge that any such action currently is contemplated.

         (d) Sublessor has not received any notice from any insurance company of
any defects or inadequacies  in the Sublease  Premises or any part thereof which
could adversely affect the insurability of the Sublease Premises or the premiums
for the insurance thereof.

19.2 Sublessee's  Representations and Warranties.  As an inducement to Sublessor
to enter the  Sublease,  to  Sublessee's  actual  current  knowledge,  Sublessee

<PAGE>


         (a) There are no pending or threatened  actions,  suits or  proceedings
before any court or  administrative  agency  against  Sublessee or third parties
which could,  in the aggregate,  adversely  affect the Sublease  Premises or any
part thereof or the ability of Sublessee  to perform its  obligations  under the
Sublease, and Sublessee is not aware of any facts which might result in any such
actions, suits or proceedings.

ARTICLE 20: GENERAL PROVISIONS.

20.1  Severability.  If any term or provision  of this  Sublease  shall,  to any
extent,  be  determined  by a court of competent  jurisdiction  to be invalid or
unenforceable, the remainder of this Sublease shall not be affected thereby, and
each term and provision of this Sublease  shall be valid and  enforceable to the
fullest extent permitted by law.

20.2  Attorneys'  Fees;  Costs of Suit.  In the event of any  breach  under this
Sublease by Sublessee or Sublessor, the non-breaching party shall be entitled to
recover,  from the breaching  party,  its reasonable  attorney's  fees and other
out-of-pocket  costs incurred to enforce the provisions of this Sublease against
the breaching party or to exercise any remedy available to it in connection with
such  breach,  including  fees and costs  incurred  in  bringing  any  action or
proceeding  for any relief  arising  out of this  Sublease,  but in the event of
litigation,  the  prevailing  party shall be entitled to recover its  reasonable
attorneys' fees and costs from the other party only as determined by the court.

20.3 Waiver.  No covenant,  term or  condition  or the breach  thereof  shall be
deemed waived, except by written consent of the party against whom the waiver is
claimed,  and any waiver of the breach of any covenant,  term or condition shall
not be deemed to be a waiver of any other  covenant,  term or  condition  or any
subsequent  failure to perform  the same or any other  such  term,  covenant  or
condition.  Acceptance by Sublessor of any  performance  by Sublessee  after the
time the same shall have become due shall not  constitute  a waiver by Sublessor
of the breach or default of any  covenant,  term or condition  unless  otherwise
expressly agreed to by Sublessor in writing.

20.4 Brokerage Commissions. The parties represent and warrant to each other that
they have dealt with no brokers,  finders,  agents or other person in connection
with the transaction contemplated hereby to whom a brokerage or other commission
or fee may be  payable,  except for the  brokers  named in Article 1, whose fees
shall be paid  pursuant to a separate  agreement.  Each party  shall  indemnify,
defend and hold the other  harmless  from any claims  arising from any breach by
the indemnifying party of the representation and warranty in this Section.  

20.5 Binding  Effect.  Preparation  of this Sublease by Sublessor or Sublessor's
agent and  submission  of the same to Sublessee  shall not be deemed an offer to
lease. This Sublease shall become binding upon Sublessor and Sublessee only when
fully executed by Sublessor and Sublessee.  Sublessor and Sublessee  acknowledge
and agree that this Sublease is expressly conditioned upon obtaining the consent
of Master  Lessor  hereto  following  such  fully  execution  by  Sublessor  and
Sublessee.  In the event such consent is not so obtained within  forty-five (45)
days following the date of this Sublease, then this Sublease shall automatically
terminate and be without  further force or effect,  and Sublessor shall promptly
return to Sublessee  the advance rent and Security  Deposit paid by Sublessee to
Sublessor pursuant to Sections 5.4 and Article 6 above.

20.6 Entire  Agreement.  This instrument and the Furniture  Rental  Agreement of
even date  herewith,  along with any  exhibits  and addenda to those  documents,
constitutes the entire agreement between Sublessor and Sublessee relative to the
Sublease Premises.  This Sublease may be altered,  amended or revoked only by an
instrument in writing signed by both Sublessor and Sublessee.  There are no oral
agreements or representations  between the parties affecting this Sublease,  and
this  Sublease  supersedes  and  cancels  any  and  all  previous  negotiations,
arrangements, brochures, agreements, representations and understandings, if any,
between the parties hereto.

the  payment  of Rent and  performance  of all other  obligations  of  Sublessee
hereunder,  Sublessee  shall be entitled to possession of the Sublease  Premises
for the  Sublease  Term,  in  accordance  with and  subject to the terms of this
Sublease.

20.8 Execution. This Sublease may be executed in one or more counterparts,  each
of which shall be considered an original counterpart,  and all of which together
shall  constitute  one and the  same  instrument.  Each  person  executing  this
Sublease represents that the execution of this Sublease has been duly authorized
by the party on whose behalf the person is executing this Sublease.

20.9  Approvals.   Whenever  this  Sublease   requires  an  approval,   consent,
designation,  determination,  selection  or  judgment  by  either  Sublessor  or
Sublessee,  such approval,  consent,  designation,  determination,  selection or

Dear Sandy:

1.   Your  employment  with the  Company  will  terminate  on  October  31,1998.
     Although  you are not  otherwise  entitled to receive any further  payments
     from the  Company,  after you sign this letter the Company  will pay you in
     twelve equal  installments over a six month period,  eighty-eight  thousand
     one hundred and thirty dollars ($88,130), less all applicable withholdings,
     which is equal to six (6) months of your current  base salary.  The Company
     will pay directly to Guardian your monthly medical insurance premiums for a
     period of six months after October 31, 1998,  for the level of your medical
     insurance  coverage  in  effect on  October  31,  1998.  Thus you will have
     company paid COBRA coverage through April 30, 1999.

2.   You may take off as much time as is necessary to search for new employment.
     On your  termination  date  you will be paid  for all of your  accrued  but
     unused vacation time.

3.   In the event that you have not found regular full time employment by May 1,
     1999, an  additional  three months salary will be paid as severance as well
     as three additional months of company paid COBRA benefits.

4.   You will  also  receive  out  placement  assistance  in the  amount  of two
     thousand five hundred dollars ($2,500).

5.   You  will  remain  on the  Board  for the  foreseeable  future  with  Board
     compensation per plan.

6.   You will  retain  use of your  office  and your  voice  mail until your job
     search is complete.

7.   In consideration for receiving the severance  payments described above, you
     waive and  release  and  promise  never to assert  any  claims or causes of
     action,  whether or not now  known,  against  Company or its  predecessors,
     successors,   subsidiaries,  officers,  directors,  agents,  employees  and
     assign,  with respect to any matter  arising out of or connected  with your
     employment  with  the  Company  or  the  termination  of  that  employment,
     including  without  limitation,  claims of  wrongful  discharge,  emotional
     distress,  defamation,  breach of contract,  breach of the covenant of good
     faith and fair  dealing,  any claims of  discrimination  based on sex, age,
     race,  national origin, or on any other basis, under Title VII of the Civil
     Rights Act of 1964, as amended,  the California Fair Employment and Housing
     Act, the Age  Discrimination  in Employment Act of 1967, and all other laws
     and regulations relating to employment.

     options will remain available for purchase until sixty days after the later
     of: (1) termination of severance, or (2) termination of board service.
