                                              The MicroLap
                                                 System
 
                   [artwork depicting MicroLap system in use]
 
    The MicroLap  system  includes a  proprietary  microlaparoscope,  disposable
introducers  (for placement of  the MicroLap and  microsurgical instruments into
the abdomen)  and  a  broad  line of  microsurgical  instruments  for  use  with
the system. Imagyn has sold over 850 MicroLap microlaparoscopes.
 
    Imagyn's  proprietary micro-optics technology has enabled the development of
a 2 millimeter-diameter  microlaparoscope with resolution  and light  efficiency
characteristics  which  the  Company  believes  are  comparable  to conventional
laparoscopes.
 
    Using the MicroLap system, physicians are able to perform a wide variety  of
diagnostic  and  operative  procedures  outside  the  hospital  without  general
anesthesia and at a reduced cost, with less patient discomfort and with  shorter
recovery time.
 
                 [diagram of a 10 millimeter-diameter cylinder]
                 [diagram of a 2 millimeter-diameter cylinder]
The  MicroLap microlaparoscope, at slightly less than 2 millimeters in diameter,
is 80% smaller than conventional 10 millimeter-diameter laparoscopes.
 
Imagyn's disposable  introducers  facilitate  atraumatic  insertion  and  secure
placement  of the MicroLap  and microsurgical instruments  through the abdominal
wall.

                                 The MicroSpan
                                     System
 
                  [artwork depicting MicroSpan system in use]
 
    The  MicroSpan system  incorporates a new  high resolution microhysteroscope
and a new uterine access device to enable the physician to atraumatically access
and visualize the interior of the uterus.
 
The disposable micro-access device provides simultaneous transcervical access to
the uterus for both the microhysteroscope and microsurgical instruments  without
the need for cervical dilation required by conventional hysteroscopy systems.
 
The  design of  the Company's  proprietary micro-access  device will  enable the
physician to use  surgical instruments  of the  same diameter  used in  standard
hysteroscopy  procedures  for  effective  tissue sampling  and  removal  of many
uterine lesions.
 
    Using the MicroSpan system, physicians are able to perform a wide variety of
diagnostic  and  operative  procedures  outside  the  hospital  without  general
anesthesia  and at reduced  cost, with less patient  discomfort and with shorter
recovery time.
 
                   [photo of components of MicroSpan system]
 
    The MicroSpan system includes a proprietary microhysteroscope, a proprietary
disposable micro-access device and a line of microsurgical instruments.
 
THE MICROSPAN MICROHYSTEROSCOPY SYSTEM HAS NOT BEEN CLEARED BY THE FDA FOR
COMMERCIAL SALE IN THE UNITED STATES. THE PROCESS OF OBTAINING FDA CLEARANCE MAY
BE LENGTHY, AND THERE CAN BE NO ASSURANCE THAT THE MICROSPAN SYSTEM WILL BE
CLEARED BY THE FDA.

                                     tube.
 
        [artwork depicting step 2 of the deployment of Ovation catheter]
 
 2. The membrane is slowly unrolled in the fallopian tube after applying fluid
                          pressure into the catheter.
 
        [artwork depicting step 3 of the deployment of Ovation catheter]
 
   3. The falloposcope is advanced through the central channel of the balloon
                      membrane to allow for visualization.
 
                                  The Ovation
                                    Systems
 
    The Ovation falloposcopy  and tubal recanalization  systems are designed  to
enable  the physician  to access,  navigate and  view the  entire length  of the
fallopian tube.
 
    The Ovation falloposcopy system enables the physician to view and accurately
evaluate the patency and overall health  of the interior of the fallopian  tube.
Due  to the unique  self-steering characteristics of  the Ovation system, visual
guidance with hysteroscopy or ultrasound is  not required nor is there the  need
for  concurrent  laparoscopic manipulation  of the  fallopian tube.  The Ovation
falloposcopy system has been specifically designed to facilitate fallopian  tube
diagnosis in the physician's office.
 
    The  Ovation tubal  recanalization system  has been  shown in  a controlled,
multi-center clinical  trial in  Japan to  unblock occluded  fallopian tubes,  a
process  known as tubal  recanalization. The Company  has received approval from
the Japanese  Ministry  of  Health  and Welfare  to  market  the  Ovation  tubal
recanalization system.

    The  Ovation  falloposcopy and  tubal  recanalization systems  consist  of a
proprietary  0.5  millimeter-diameter,  flexible  falloposcope,  a   proprietary
catheter  and a specially  designed irrigation pump. Imagyn  has sold over 6,000
Ovation catheters.
 
THE OVATION FALLOPOSCOPY  AND TUBAL RECANALIZATION  SYSTEMS ARE  INVESTIGATIONAL
DEVICES  AND HAVE NOT BEEN APPROVED BY THE FDA FOR COMMERCIAL SALE IN THE UNITED
STATES. THE PROCESS OF OBTAINING FDA APPROVAL  MAY BE LENGTHY, AND THERE CAN  BE
NO ASSURANCE THAT THE OVATION SYSTEMS WILL BE APPROVED BY THE FDA.

    THIS PROSPECTUS CONTAINS FORWARD-LOOKING  STATEMENTS THAT INVOLVE RISKS  AND
UNCERTAINTIES.   THE  COMPANY'S  ACTUAL  RESULTS   OF  OPERATIONS  COULD  DIFFER
MATERIALLY FROM THOSE ANTICIPATED IN SUCH FORWARD-LOOKING STATEMENTS AS A RESULT
OF CERTAIN  FACTORS  SET  FORTH  UNDER "RISK  FACTORS"  AND  ELSEWHERE  IN  THIS
PROSPECTUS.
 
                                  The Company
 
    Imagyn  Medical,  Inc. ("Imagyn"  or  the "Company")  designs,  develops and
markets micro-invasive, cost-effective  devices for diagnosis  and treatment  of
gynecological  and reproductive disorders.  The Company's proprietary technology
platform based on micro-optics and micro-access devices provides physicians with
the ability to  atraumatically access  and visualize the  abdominal cavity,  the
uterus  and  the  fallopian  tubes.  Imagyn's  proprietary  micro-optics  enable
physicians to visualize  a patient's  internal anatomy with  the resolution  and
light  efficiency of larger, more invasive devices commonly used today. Imagyn's
proprietary,  disposable  micro-access  devices  enable  physicians  to  perform
certain procedures outside the hospital without the need for general anesthesia.
The Company's principal product systems based on these core technologies are the
MicroLap microlaparoscopy system, the MicroSpan microhysteroscopy system and the
Ovation systems for infertility indications. Compared to traditional procedures,
the  Company's  product  systems  facilitate  earlier  definitive  diagnosis and
treatment, significantly lower the procedure cost associated with more  invasive
surgery and reduce patient discomfort, recovery time and morbidity. To date, the
Company  has sold  over 850  MicroLap microlaparoscopes  and over  6,000 Ovation
catheters.
 
    Imagyn's diagnostic and operative  micro-invasive product systems address  a
broad  continuum of gynecological  and reproductive disorders  affecting a large
number of women, including pelvic  pain, uterine disorders and infertility,  and
provide  a less invasive procedure for  tubal sterilization. Because of the high
incidence of these  disorders and  the popularity  of tubal  sterilization as  a
contraceptive  method, large markets exist for devices that treat such disorders
and  that   facilitate  tubal   sterilization.   First,  pelvic   pain   affects
approximately 6 million women in the United States and can be caused by a number
of   serious   conditions,   including  endometriosis,   adhesions   and  pelvic
inflammatory disease. Second, uterine disorders affect approximately 25  million
women  in the United States and  may lead to significant complications including
uterine  bleeding,  acute  pain  and  infertility.  Third,  infertility  is   an
increasingly  common  and often  emotionally  traumatic condition  which affects
approximately 5 million women in the United States. Finally, tubal sterilization
is chosen as  a permanent  contraceptive method by  approximately 800,000  women
annually  in the United States.  Despite the large size  of these markets, there
can be no assurance that the Company's product systems will be accepted and will
compete effectively in any of these markets. Market acceptance of the  Company's
product  systems  will  be  dependent  upon,  among  other  things,  physicians'
determinations that the Company's  product systems and  the procedures in  which
they  are intended  to be  used are safe  and effective  alternatives to current
hospital-based procedures and demonstrate clincial utility, and can be used in a
cost-effective manner.
 
    The Company's product systems enable physicians to access and visualize  all
of  the organs of a woman's reproductive system outside the hospital without the
need for general anesthesia. The MicroLap system, which enables the physician to
access the  abdominal  cavity  without  the  need  for  post-operative  sutures,
includes  a  2 millimeter-diameter  microlaparoscope  with resolution  and light
efficiency characteristics which the Company believes are comparable to those of
standard 10 millimeter-diameter laparoscopes. The MicroSpan system  incorporates
a  new  high resolution  microhysteroscope and  a new  uterine access  device to
enable the physician to atraumatically access and visualize the interior of  the
uterus.  The  MicroLap and  MicroSpan systems  enable  physicians to  access the
abdominal cavity and the uterus  for treatment with the Company's  microsurgical
instruments.  The  Ovation  systems  are designed  to  enable  the  physician to
atraumatically access, navigate and visualize the entire length of the fallopian
tubes. Imagyn's product systems are designed to offer significant advantages for
physicians, patients and  health care payors.  For physicians, Imagyn's  systems
facilitate improved diagnosis and enhanced practice management. The MicroLap and
MicroSpan systems require limited training for physicians familiar with standard
laparoscopy and hysteroscopy techniques, although more training will be required
for use of the Ovation systems. For patients, Imagyn's systems reduce trauma and
the risk of complications and shorten recovery times as compared to traditional,
more  invasive procedures. For payors, Imagyn's systems can reduce cost, provide
earlier, definitive  diagnosis and  increase patient  satisfaction. Due  to  the
small  size of the Company's micro-access devices, the Company's product systems
are generally not appropriate for use in procedures which involve the removal of
substantial amounts of tissue or organs, such as the laparoscopic removal of the
gall bladder. In addition, procedures using the Company's product systems should
be avoided with patients who have a heightened risk of uncontrollable  bleeding,
are pregnant or have advanced cardiovascular disease.
 
    The  Company's  marketing  and  distribution strategy  consists  of  two key
elements: (i) focusing its  direct sales and  marketing resources on  gynecology
group   practices,  surgery   centers  and  infertility   specialists  and  (ii)
establishing strategic marketing alliances with major medical products companies
to accelerate  sales  growth, increase  geographic  market coverage  and  access
 
                                       3
<PAGE>
particular  markets and customers that can  be more effectively addressed by the
sales organizations of these  companies. To date, the  Company has entered  into
two  strategic marketing alliances, an  exclusive international and co-exclusive
domestic distribution agreement with United States Surgical Corporation ("USSC")
for the MicroLap system and an agreement with Terumo Corporation ("Terumo")  for
Japanese distribution and manufacturing rights for the Ovation systems.
 
    To date, the Company has received United States Food and Drug Administration
("FDA")  510(k)  clearances  for  the  MicroLap  system  for  diagnostic  and/or
operative use for pelvic  pain, tubal sterilization  and other indications.  The
Company  has submitted 510(k) clearance applications for the MicroSpan system to
the FDA.  The  Ovation  tubal recanalization  system,  which  unblocks  occluded
fallopian  tubes, recently  received Japanese  regulatory approval.  The Ovation
falloposcopy system, which is designed to enable physicians to visually diagnose
the interior of  fallopian tubes, is  undergoing clinical trials  in the  United
States  under an investigational device exemption ("IDE") issued by the FDA. The
Company  anticipates  completion  of  the  clinical  trials,  with  a   targeted
enrollment  of  100  patients, in  1996.  There  can be  no  assurance  that the
MicroSpan system or the Ovation systems will  be cleared or approved by the  FDA
for their intended uses on a timely basis, if at all.
 
                                  Risk Factors
 
    An  investment  in the  shares  of Common  Stock  offered hereby  involves a
significant degree  of  risk, including  the  risk that  the  Company's  product
systems  may  not gain  market acceptance,  the Company's  limited manufacturing
capacity and experience, the Company's  dependence upon sole and limited  source
suppliers  and strategic  marketing alliances,  the Company's  limited sales and
marketing experience, fluctuations  in the Company's  results of operations  and
risks associated with government regulation and the regulatory approval process.
Investors should refer to "Risk Factors" set forth at pages 5 to 15.
 
    The  Company  will not  be able  to  market the  MicroSpan microhysteroscopy
system or the Ovation falloposcopy system in the United States unless and  until
it obtains clearance or approval from the FDA and there can be no assurance that
the  Company will obtain FDA clearance or approval for such product systems on a
timely basis, if at all.

                                  RISK FACTORS
 
    IN EVALUATING THE COMPANY'S BUSINESS, PROSPECTIVE INVESTORS SHOULD CAREFULLY
CONSIDER  THE  FOLLOWING  RISK  FACTORS IN  ADDITION  TO  THE  OTHER INFORMATION
APPEARING  IN  THIS   PROSPECTUS.  THIS   PROSPECTUS  CONTAINS   FORWARD-LOOKING
STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS OF
OPERATIONS   COULD   DIFFER   MATERIALLY  FROM   THOSE   ANTICIPATED   IN  THESE
FORWARD-LOOKING STATEMENTS  AS A  RESULT OF  CERTAIN FACTORS  SET FORTH  IN  THE
FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS PROSPECTUS.
 
Uncertainty of Market Acceptance
 
    Imagyn  is substantially dependent upon the success and market acceptance of
its MicroLap  microlaparoscopy system,  MicroSpan microhysteroscopy  system  and
Ovation  systems.  The Company's  MicroLap  and Ovation  systems  have generated
limited revenue  to date  and the  MicroSpan system  has not  been  commercially
introduced.  The Company  believes that  physicians will  not use  the Company's
product systems  unless  they  determine  that  such  product  systems  and  the
procedures  in  which  they are  intended  to  be used  are  safe  and effective
alternatives to  current  hospital-based  procedures  and  demonstrate  clinical
utility,  and can be used in a  cost-effective manner. 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 health care payors,
even if necessary international and  United States regulatory and  reimbursement
approvals are obtained.
 
    The  Company believes  that market  acceptance of  the MicroLap  system will
depend on the Company's  and USSC's ability to  provide evidence to the  medical
community  of the effectiveness of micro-invasive laparoscopic procedures and of
the benefits to patients, physicians  and payors of such micro-invasive  surgery
performed  outside the hospital.  Market acceptance will  also be dependent upon
the durability and performance of the MicroLap. The Company believes that market
acceptance of  its MicroSpan  system will  depend on  the Company's  ability  to
demonstrate the utility of diagnostic and operative hysteroscopy. In particular,
market  acceptance of diagnostic  microhysteroscopy may be  limited because some
physicians and payors view hysterectomy, the surgical removal of the uterus,  as
the  appropriate therapy  for a variety  of uterine disorders  as a hysterectomy
precludes the recurrence  of the uterine  disorders it was  performed to  treat.
Such  physicians or  payors may  be reluctant to  perform or  pay for diagnostic
microhysteroscopy to visualize the uterus  if the ultimate treatment outcome  is
likely  to be a hysterectomy. In addition, several less-invasive alternatives to
operative hysteroscopy are either under development, in clinical trials or  have
recently  been introduced. Market acceptance of  diagnostic use of the MicroSpan
system may also therefore  be dependent upon acceptance  of these less  invasive
alternatives  to hysterectomy. Market  acceptance of the  MicroLap and MicroSpan
systems will also  be dependent upon  the willingness of  physicians to  perform
laparoscopic   and  hysteroscopic  procedures,  which  have  traditionally  been
performed in the hospital under general anesthesia, in an office or clinic. Such
market  acceptance  may  also  be   dependent  upon  the  ability  of   MicroLap
laparoscopes  and MicroSpan microhysterscopes to be used with a broad variety of
sterilization methods. Addition of other  sterilization methods to the  MicroLap
microlaparoscope  labelling  may require  submission of  a new  510(k) clearance
application to the FDA. Preferred  sterilization methods may differ among  users
of  the  Company's products  with, for  example, physician's  offices preferring
different  methods   than   hospitals   or   surgery   centers.   The   MicroLap
microlaparoscope   is  currently  labelled  for   use  only  with  a  particular
sterilization method,  and  the Company  is  aware  that certain  users  of  its
products are using, and prefer to use, other sterilization methods. In addition,
physician  acceptance of microlaparoscopy and  microhysteroscopy may be affected
by the unwillingness of physicians  to perform these procedures under  conscious
sedation  rather than under general  anesthesia, availability in the physician's
office of necessary ancillary  capital equipment such  as medical video  cameras
and  light sources,  and availability  of a  sufficiently large  patient base to
support an office-based microsurgery practice.
 
    The Company  believes that  market acceptance  of the  Ovation systems  will
depend  on the Company's ability to  demonstrate the utility of falloposcopy and
recanalization in diagnosing and managing  infertility and generate an  interest
on  the part of  physicians to be  trained to perform  such procedures using the
Company's Ovation systems. There can be  no assurance that physicians and  other
potential  users of the Company's  products will be willing  to learn to perform
microlaparoscopy, microhysteroscopy or falloposcopy with the Company's  products
or  that the Company will be able to train such users to learn these techniques.
Market acceptance will also  be dependent upon  the availability of  third-party
reimbursement  for  procedures  performed  using  the  Company's  products.  See
"Business--Third-Party Reimbursement."
 
                                       5
<PAGE>
    Because the success of  each of the Company's  product systems depends  upon
acceptance  by physicians and health care payors of such product systems and the
procedures in which  they are  intended to be  used, the  Company believes  that
recommendations and endorsements by influential physicians will be essential for
market  acceptance of the Company's products. There can be no assurance that any
such recommendations or endorsements will be obtained. 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.
See "Business--Product Systems."
 
Limited Operating History; Commercial Scale-Up Risk
 
    The Company has  a limited  history of  operations. Since  its inception  in
August  1989, the Company has been engaged primarily in research and development
of  its  Ovation  systems,   MicroLap  microlaparoscopy  system  and   MicroSpan
microhysteroscopy system. The Company has sustained substantial operating losses
since  inception and there can be no  assurance that the Company will achieve or
sustain profitability. To date, the Company has generated only limited revenues,
primarily from sales of its Ovation  systems in international markets and  sales
of  its MicroLap system in both the United States and international markets. The
Company does  not have  experience in  manufacturing, marketing  or selling  its
products  in the quantities  that will be  necessary for the  Company to achieve
significant product revenues or  profitability. There can  be no assurance  that
any  of the Company's  products will be successfully  commercialized or that the
Company will achieve significant revenues. Whether the Company can  successfully
manage the transition to a larger-scale commercial enterprise will depend upon a
number  of factors, including  the Company's ability  to increase its commercial
manufacturing capability and establish marketing and sales capabilities and  its
ability   to   develop   additional  distribution   relationships   in  targeted
international markets.  There can  be no  assurance that  the Company  will  not
experience  future  difficulties  related  to  the  Company's  transition  to  a
larger-scale commercial enterprise, which could  have a material adverse  effect
on  the Company's business,  financial condition and  results of operations. See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations."
 
Limited Manufacturing Capacity and Experience
 
    The  Company has  only limited experience  in manufacturing  its products in
commercial quantities  and has  not  manufactured any  of  its products  in  the
quantities  that will be necessary for  achievement of significant product sales
or profitability. The  Company manufactures  its proprietary  microlaparoscopes,
falloposcopes,  linear everting catheters and micro-invasive access devices in a
clean room at its facility, and plans to expand its manufacturing facilities and
operations in 1996. The manufacturing processes for microlaparoscopes and linear
everting catheters are  complex and require  precision in producing,  assembling
and  testing finished products. Many of the  steps in the assembly process, such
as grinding  and polishing  lenses and  optical fibers,  are performed  under  a
microscope,  requiring  up to  80x magnification.  In addition  to manufacturing
certain of  its  products, Imagyn  purchases  other components  of  its  product
systems  from  outside vendors.  Light sources,  medical  video cameras  and the
microsurgical instruments used in conjunction with the MicroLap are manufactured
to the Company's  specifications by  various vendors.  None of  such vendors  is
obligated  to continue  to supply  the Company  with such  products, nor  is the
Company obligated to purchase from any particular vendor. The Company  currently
contracts  with third parties to manufacture certain components of its products.
Final assembly and packaging is currently performed by the Company in-house  and
sterilization is performed by outside vendors.
 
    The  Company  has limited  manufacturing capacity  and  will be  required to
increase both  its  in-house  manufacturing  capability  and  the  size  of  its
manufacturing  facilities. There  can be no  assurance that the  Company will be
able to complete its facility expansion, attract, train and retain the  required
personnel,  including  personnel  skilled  in  micro-optics  assembly processes,
obtain regulatory approval to manufacture  its products in these facilities,  or
increase its manufacturing capability and capacity in a timely manner. There can
be  no assurance that reliable, high-volume  manufacturing can be established or
maintained at  commercially reasonable  costs  on a  timely  basis, or  at  all.
Manufacturers  often encounter  difficulties in  scaling up  production of their
products, including problems  involving production yields,  quality control  and
assurance, component supply and shortages of qualified personnel. If the Company
is  unable  to increase  its in-house  manufacturing capability  or successfully
complete the expansion of its manufacturing  facilities in a timely manner,  the
Company   may   need   to  obtain   alternative   manufacturing   facilities  or
 
                                       6
<PAGE>
establish contract manufacturing for its  products, and delays associated  with,
or  inability  to  establish, such  additional  capacity could  have  a material
adverse effect on  the Company's  business, financial condition  and results  of
operations. See "Business--Manufacturing."
 
Dependence Upon Sole and Limited Source Suppliers
 
    The Company currently obtains certain components of its product systems from
single  source suppliers. These components include the optic image fiber used in
the MicroLap, a similar version of which will also be used in the MicroSpan, and
the  camera  and  light  source  used  in  connection  with  the  Ovation  tubal
recanalization  system. Currently, the  Company has a  supply agreement with the
MicroLap image fiber  supplier; however,  there can  be no  assurance that  such
supplier  will be able to or will continue to supply image fibers to the Company
in the amounts and at the times needed by the Company or that other  disruptions
in  supply will not  occur. The number  of manufacturers capable  of making such
optical image fibers  is limited  and, to date,  the Company  has not  qualified
additional suppliers for such optical image fibers. There can be no assurance as
to  when  or  whether  the  Company will  be  able  to  qualify  such additional
suppliers. The  Company's prior  supplier  of medical  video cameras  and  light
sources  for the Ovation System ceased  manufacturing such products in late 1995
as a result of financial difficulties,  which resulted in a temporary  inability
of the Company to supply such components to Terumo. As a result, the Company was
unable  to ship Ovation medical video cameras  and light sources to Terumo for a
period of approximately six months. There can be no assurance that future supply
disruptions for such components will not  occur. The Company also uses a  single
vendor  for sterilization of  its products, and  disruptions in sterilization of
finished products could adversely affect the Company. Furthermore, there can  be
no  assurance that the Company will  not encounter future component shortages or
other disruptions in supply of materials or services. Delays associated with any
future raw materials or component 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.  See
"Business--Manufacturing."
 
Dependence Upon Strategic Marketing Alliances
 
    A key element of the Company's strategy has been and is expected to continue
to be  the establishment  of strategic  marketing alliances  with major  medical
products  companies. To date, the Company  has entered into two such agreements.
Product sales to Terumo and USSC accounted for 25% and 11%, respectively, of net
sales in 1995. Product sales to USSC accounted for 89% of net sales in the three
months ended March 31, 1996. The Company anticipates that it will continue to be
dependent upon these companies for a  significant portion of its future  product
sales.
 
    In October 1995, the Company entered into a distribution agreement with USSC
pursuant  to which USSC was granted exclusive international marketing rights for
the Company's MicroLap system in all international markets (excluding China  and
India).  As a result, the Company is dependent upon USSC for international sales
of these  products. USSC  was also  granted, on  a co-exclusive  basis with  the
Company,  marketing rights to the MicroLap system in the United States. The USSC
agreement contains certain  provisions limiting  the amount  of price  increases
that  may be passed on to USSC  by Imagyn. These provisions may adversely affect
the Company's future gross margins on MicroLap products sold to USSC. USSC  also
has  the right  to require the  Company, if  it is unable  during specified time
periods to  meet USSC's  requirements for  MicroLap products,  to grant  certain
manufacturing rights to USSC. In the event that Imagyn were to fail to meet such
requirements  and  USSC  exercised  such  rights,  Imagyn's  business, financial
condition and results of operations could be materially and adversely  affected.
The  Company's agreement  with USSC  may be terminated  by USSC  upon six months
notice at any time after October 23, 1997. Imagyn may terminate the agreement at
any  time  if  USSC  introduces   products  which  compete  with  the   MicroLap
microlaparoscope,  which could have  a material adverse  effect on the Company's
ability to market and sell the MicroLap in the future.
 
    In November  1992, the  Company entered  into a  license, manufacturing  and
distribution agreement with Terumo for exclusive rights to the Company's Ovation
systems  for sales and distribution in Japan. Imagyn is obligated to transfer to
Terumo by August 1997 the manufacturing  know-how necessary to enable Terumo  to
manufacture  linear everting  catheter systems for  sale to  customers in Japan.
Once Terumo begins manufacturing  products for resale in  Japan, Terumo will  be
obligated  to pay Imagyn  royalties on products  sold in Japan.  The transfer of
manufacturing know-how  involves  certain risks.  In  particular, in  the  event
Imagyn is unable to transfer such
 
                                       7
<PAGE>
manufacturing  know-how, Imagyn  may be  subject to  certain financial penalties
pursuant  to  the  agreement.  Terumo   may  also  experience  difficulties   in
manufacturing  linear everting  systems, including  difficulties associated with
manufacturing scale-up, quality control and other manufacturing-related problems
that could affect Terumo's product sales,  which in turn would adversely  affect
Imagyn's  royalty income. Terumo  also does not  have other significant products
for the gynecology  or infertility  market and  Terumo's lack  of experience  in
these  markets  could  adversely  affect Terumo's  ability  to  market  and sell
Imagyn's linear everting systems in Japan.
 
    The Company  is dependent  upon USSC  and Terumo  for marketing,  sales  and
distribution  of the  products covered by  their respective  agreements in their
respective territories.  The Company  is  also dependent  upon USSC  and  Terumo
devoting  sufficient resources to the promotion  of their respective products in
their respective territories. In addition, the Company's products may  represent
relatively  small market  segments for  both USSC and  Terumo and,  as a result,
either USSC  or Terumo  may not  devote sufficient  attention to  the  Company's
products. Furthermore, although the Company has certain contractual rights under
its  agreements with USSC  and Terumo, any  legal remedies the  Company may have
under such agreements in the event of breach would be costly to exercise and may
not provide the Company with meaningful relief. In the event that USSC or Terumo
are unable  to  obtain  necessary  regulatory  approvals  for  their  respective
products in their respective territories, fail to devote sufficient resources to
promote  the  Company's products,  or fail  to support  reimbursement approvals,
sales of the products covered  by the agreements with  USSC and Terumo could  be
materially  and adversely affected, which in  turn would have a material adverse
effect on the Company's business, financial condition and results of operations.
The Company has also agreed to indemnify both USSC and Terumo against claims  of
infringement  of intellectual property rights. Furthermore, the Company's rights
to terminate the agreements with USSC and Terumo are limited, and,  accordingly,
the  Company may  be unable to  establish alternative  marketing or distribution
arrangements if the  agreements with  USSC and  Terumo are  not successful.  The
failure  or loss of strategic  alliances with USSC and  Terumo, or the Company's
inability to  enter into  future  necessary strategic  alliances, would  have  a
material  adverse  effect on  the  Company's business,  financial  condition and
results of operations. See "Business-- Strategic Marketing Alliances."
 
Limited Sales and Marketing Experience
 
    The Company has only limited experience marketing and selling its  products,
and  does not have  experience marketing and selling  its products in commercial
quantities. The Company  currently does  not have a  direct sales  force in  the
United   States  and  has  only  three  direct  international  sales  personnel.
Domestically, the Company is marketing the MicroLap system primarily through its
collaborative relationship  with USSC.  The Company  anticipates establishing  a
domestic  sales  force and  increasing  the scope  of  its marketing  efforts to
support sales of the MicroLap system  and future commercial introduction of  the
MicroSpan microhysteroscopy system and the Ovation systems in the United States.
Establishing  marketing  and sales  capability  sufficient to  support  sales in
commercial  quantities   will  require   significant  resources   and  will   be
time-consuming,  and there can be no assurance  that the Company will be able to
recruit and  retain qualified  marketing personnel,  direct sales  personnel  or
contract  sales  representatives in  a timely  manner or  that future  sales and
marketing efforts of the Company will  be successful. There can be no  assurance
that  the  Company  will  be successful  in  establishing  marketing,  sales and
distribution channels in the  United States or  internationally. The failure  to
establish  and  maintain  effective  distribution  channels  for  the  Company's
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.    See
"Business--Marketing, Sales and Distribution."
 
Government Regulation
 
    The  manufacture and sale of medical devices, such as the Company's MicroLap
system, MicroSpan microhysteroscopy system and  Ovation systems, 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 FDA and corresponding state agencies, such as the California
Department of Health Services ("CDHS"). The process of obtaining and maintaining
required   regulatory  clearances  and  approvals   is  lengthy,  expensive  and
uncertain. The FDA requires companies desiring to market a new medical device or
an existing medical device for a major change in intended use 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 medical device into the  market. In addition, changes to a
medical device that significantly  affect the safety or  efficacy of the  device
 
                                       8
<PAGE>
are  also subject  to FDA review  and clearance or  approval. Although generally
believed to be a shorter, less costly regulatory path than a PMA, the process of
obtaining a 510(k)  clearance generally  requires the  submission of  supporting
data, which may include data from clinical trials of the device. The time period
required  to assemble and compile this data  can be extensive and can extend the
regulatory process for a considerable length  of time. The PMA process can  take
several  years  or longer  from initial  filing and  requires the  submission of
extensive clinical data and supporting information.
 
    Sales of  medical  devices outside  of  the  United States  are  subject  to
international  regulatory requirements  that vary  from country  to country. The
time required  to obtain  approval for  sale internationally  may be  longer  or
shorter  than that required  for FDA approval, and  the requirements may differ.
USSC  is  responsible  for  obtaining  appropriate  product  registrations   and
regulatory  approvals for  the MicroLap  system in  those markets  in which USSC
plans to  distribute the  system. Terumo  has obtained  regulatory approval  for
marketing  the Ovation  tubal recanalization system  in Japan  from the Japanese
Ministry of Health and Welfare. However, such approval is subject to  continuing
compliance by Terumo with the requirements of the Ministry of Health and Welfare
and  such approval could be  suspended in the event  Terumo fails to comply with
such requirements.  In  Europe, the  Company  will  be required  to  obtain  the
certifications  necessary  to enable  the CE  mark,  an international  symbol of
adherence to quality assurance standards and compliance with applicable European
Union Medical Device  Directives, to  be affixed  to the  Company's products  by
mid-1998  in order to continue sales in  member countries of the European Union.
The Company has not obtained such certifications, and there can be no  assurance
that  it will be able to do so in  a timely manner, if at all. 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
that  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.
 
    There  can be no assurance that the Company will be able to obtain necessary
510(k) clearances or PMA approvals to  market its products in the United  States
for their intended uses on a timely basis or at all, and delays in receipt of or
failure  to receive such approvals, the loss of previously received 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.
 
    Regulatory clearances  or approvals,  if  granted, may  include  significant
limitations  on  the indicated  uses  for which  the  Company's products  may be
marketed. Furthermore, if safety  or efficacy problems  occur after the  product
reaches the market, the FDA may take steps to prevent or limit further marketing
of  the product. 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 or  marketing 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.  The
Company  has obtained and is required to maintain a medical device manufacturing
license from  the  CDHS.  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  laws and  regulations  or  adoption  of new
government regulations or policies could prevent or delay regulatory approval of
the Company's products, and there can be no assurance that the Company would not
be required to incur significant costs in  the future to comply with such  laws,
regulations or policies. See "Business--Government Regulation."
 
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. As of
April  15,  1996,  the  Company  held  13  issued  United  States  patents   and
 
                                       9
<PAGE>
3  issued  foreign  patents and  had  11  United States  and  10  foreign patent
applications pending, covering various aspects of the Company's product systems.
The Company's  issued  United States  patents  cover technology  underlying  the
Ovation  systems. The expiration dates of  these patents range from October 2011
to May 2014.
 
    In addition to  its patents  and patent  applications, the  Company holds  a
license  from Baxter  Healthcare Corporation  ("Baxter") and  Thomas J. Fogarty,
M.D. ("Fogarty"),  the inventor  of the  linear everting  catheter, that  grants
Imagyn  the  exclusive,  perpetual,  worldwide use  of  patented  technology and
know-how related to  the linear everting  catheter technology in  the fields  of
obstetrics, gynecology, and infertility, in exchange for royalty payments. As of
April  15,  1996, Baxter  and  Fogarty held,  and  Imagyn has  been  granted the
exclusive license  for, 11  issued  United States  patents and  numerous  issued
foreign  patents and  pending applications  covering aspects  of linear everting
catheter technology. The  license agreement  requires that  Baxter maintain  and
prosecute  all patents and  patent applications relating  to the linear everting
catheter technology.
 
    No assurance can be given that any patents from pending patent  applications
or  from any future  patent applications will  be issued, that  the scope of any
patent protection will exclude competitors or provide competitive advantages  to
the  Company,  that  any  of  the  Company's  patents  will  be  held  valid  if
subsequently challenged or that others will not claim rights in or ownership  of
the patents and other proprietary rights held by the Company. Furthermore, there
can  be no assurance that others have  not developed or will not develop similar
products, duplicate any of the Company's products or design around the Company's
patents. In  addition,  others  may  hold or  receive  patents  or  file  patent
applications  which contain claims having a scope that covers products developed
by the Company.
 
    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. Furthermore, the Company has
obligations to  idenmify  USSC,  Terumo  and  other  international  distributors
against  claims of intellectual property infringement  and, as a result of these
provisions, could become involved in, or  forced to defend, litigation or  other
legal proceedings relating to intellectual property rights.
 
    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.
 
    In addition to patents, the Company relies on trade secrets and  proprietary
know-how,   which   it  seeks   to   protect,  in   part,   through  appropriate
confidentiality  and  proprietary   information  agreements.  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  that  proprietary  information  or  confidentiality  agreements  with
employees, consultants and others  will not be breached,  that the Company  will
have  adequate remedies for any breach, or that the Company's trade secrets will
not otherwise become  known to  or independently developed  by competitors.  See
"Business--Patents, Trade Secrets and Licenses."
 
                                       10

Uncertainty Relating to Third-Party Reimbursement
 
    In  the  United  States,  health  care  providers,  such  as  hospitals  and
physicians, that  purchase the  Company's products  and other  medical  devices,
generally  rely on third-party  payors, private health  insurance plans, federal
Medicare and  state  Medicaid to  reimburse  all or  part  of the  cost  of  the
procedure  in  which  the  medical  device  is  being  used.  Reimbursement  for
traditional laparoscopy and hysteroscopy procedures performed using devices that
have received FDA approval  has generally been available  in the United  States.
Nevertheless,  there are no specific reimbursement codes for microlaparoscopy or
microhysteroscopy procedures. There can be no assurance that reimbursement  will
be  available for procedures performed using  the Company's existing products or
future products.  Because  infertility  procedures have  not  historically  been
reimbursed  by health  care payors,  the Company believes  that it  will be very
difficult, if not impossible, to  obtain reimbursement for procedures  performed
using its Ovation systems in the United States. In addition, certain health care
providers  are  moving toward  a  managed care  system  in which  such providers
contract to  provide comprehensive  health care  for a  fixed cost  per  covered
individual.  The Company is unable  to predict what changes  will be made in the
reimbursement methods  utilized  by  third-party health  care  payors,  and  the
Company  could be  adversely affected  by changes  in reimbursement  policies of
governmental or private health care payors, particularly to the extent any  such
changes  affect reimbursement for 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  health care payors  for procedures  in
which  the Company's  products are used  or adverse changes  in governmental and
private third-party payors'  policies toward reimbursement  for such  procedures
would  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
health care payment systems.  Reimbursement and health  care payment systems  in
international markets vary significantly by country, and include both government
sponsored   and  private  health  insurance.  The  Company  is  relying  on  its
international  distributors  to  seek  reimbursement  approvals  for  procedures
performed  using its  products in  international markets.  In particular, Terumo
recently applied  for  Japanese reimbursement  approval  for the  Ovation  tubal
recanalization   system.  There   can  be   no  assurance   that  such  Japanese
reimbursement approval or any  other international reimbursement approvals  will
be  obtained in  a timely  manner, or at  all. Failure  to receive international
reimbursement  approvals  could  have  a  material  adverse  effect  on   market
acceptance  of  the Company's  products in  international markets  and therefore
could have  a  material adverse  effect  on the  Company's  business,  financial
condition and results of operations. See "Business--Third-Party Reimbursement."
 
History of Losses and Expectation of Future Losses; Fluctuations in Operating
Results
 
    The  Company has  experienced significant  operating losses  since inception
and, as of  March 31, 1996,  had an  accumulated deficit of  $22.1 million.  The
Company  expects  to  incur  substantial  additional  losses  due  to  increased
operating expenditures  primarily attributable  to the  expansion of  marketing,
sales and manufacturing activities, research and development and clinical trials
in  support of regulatory and reimbursement approvals. Results of operations may
fluctuate significantly from quarter  to quarter and  will depend upon  numerous
factors,  including  the  extent to  which  the Company's  products  gain market
acceptance,  the  timing  and  volume   of  orders  from  USSC,  Terumo,   other
international  distributors and the Company's  other customers, actions relating
to  regulatory  and   reimbursement  matters,  progress   of  clinical   trials,
introduction  of alternative  means for  microlaparoscopy, microhysteroscopy and
fallopian  tube  visualization  by  competitors  of  the  Company,  pricing   of
competitive products, the cost and effect of promotional discounts and marketing
programs  in which the  Company may be required  to engage and  the absence of a
backlog of orders.  Results of operations  will also depend  upon the amount  of
royalties  payable under  the license  from Baxter  and Fogarty  relating to the
linear everting catheter technology used in the Ovation systems. There can be no
assurance that the Company  will successfully commercialize  any of its  current
products   or   any  future   products  or   achieve  significant   revenues  or
profitability.  Profitability,   if  achieved,   may  not   be  sustained.   See
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations."
 
Competition; Uncertainty of Technological Change
 
    The medical device industry  and the market  for treatment of  gynecological
disorders   and  infertility,  in  particular,  are  intensely  competitive  and
characterized   by   rapidly   evolving   technology.   The   Company    expects
 
                                       11

competition  to increase for  devices to diagnose  and treat female reproductive
disorders. A  number  of  the  Company's  competitors  are  currently  marketing
products for use in micro-invasive procedures for the diagnosis and treatment of
gynecological  disorders.  Olympus  America, Inc.,  Origin  Medsystems,  Inc., a
subsidiary of  Guidant  Corporation,  Medical  Dynamics,  Inc.  and  Karl  Storz
Instrument Co., are currently marketing laparoscopes with diameters ranging from
1.2  millimeters  to 3.0  millimeters.  Circon-Cabot Corp.  currently  markets a
microhysteroscope, and Conceptus, Inc. is currently pursuing FDA approval for  a
guidewire-based   falloposcopy   system.  The   Company  also   faces  potential
competition from medical device  or pharmaceutical manufacturers that  currently
market  or may be  developing other medical  devices or drugs,  such as hormonal
therapies, for the treatment of uterine disorders. Other companies may choose to
enter these markets  at a  later date and  would represent  competition for  the
Company.  In addition,  the Company competes  with other companies  for sites to
conduct clinical trials.
 
    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
any which have been or are being  developed by the Company or that would  render
the Company's technologies or products obsolete or not competitive, or that such
competitors  will not succeed in  obtaining regulatory approval for, introducing
or commercializing  any such  products prior  to the  Company. There  can be  no
assurance  that  the  Company  will  be able  to  compete  successfully  or that
competition will not have a material  adverse effect on the Company's  business,
financial condition or results of operations. See "Business--Competition."
 
Dependence Upon International Distributors and Sales
 
    Since  inception, a  majority of the  Company's sales have  been outside the
United States.  USSC has  distribution rights  for the  MicroLap system  in  all
international  markets other  than China and  India and  Terumo has distribution
rights for the Ovation  systems in Japan.  The Company has  a limited number  of
international  distributors for  its Ovation  systems in  certain countries. The
Company's international sales of these products in these countries are dependent
upon the  marketing efforts  of, and  sales by,  its distributors.  The  Company
relies  on these distributors to assist it in obtaining product registration and
reimbursement approvals  in  certain  international  markets.  The  Company  has
limited  sell-through experience with certain of its distributors and has in the
past experienced situations in which distributors placed initial stocking orders
for quantities that were in excess of their end user requirements. In  addition,
if a distributor were to fail to invest adequate capital promoting the Company's
products  and training  physicians in  the proper  techniques for  utilizing the
Company's  products,  or  were  to  experience  financial  difficulty  or  cease
operations,  the Company would likely be  unable to achieve significant sales in
the  subject  territory.  Management   of  international  distributors  can   be
time-consuming  and can  be complicated  by dissimilarities  among international
markets. The Company has not enforced all periodic minimum purchase  commitments
made  by  its distributors.  Furthermore, the  Company  currently does  not have
distributors in  a number  of international  markets that  it has  targeted  and
anticipates that it will need to establish additional international distribution
relationships.  There can be no assurance that the Company will engage qualified
distributors  in  these  markets  in  a  timely  manner,  if  at  all,  or  that
distributors  will  adequately market  the  Company's products.  The  failure of
distributors to adequately promote the Company's products or the failure of  the
Company  to engage additional distributors would  have a material adverse effect
on the Company's business, financial condition and results of operations.
 
Risks of International Sales
 
    A number of risks are inherent in international operations and transactions.
International sales and operations may be limited or disrupted by the imposition
of government controls,  changes in regulatory  requirements or  interpretations
thereof, export license requirements, political instability, trade restrictions,
changes  in  tariffs,  financial  instability  of  distributors,  differences in
purchasing  systems  for  medical   products,  and  difficulties  in   staffing,
coordinating  and managing international operations. Additionally, the Company's
business, financial  condition  and  results  of  operations  may  be  adversely
affected  by fluctuations  in international currency  exchange rates  as well as
constraints on the Company's ability to  maintain or increase prices. There  can
be  no assurance that the Company will be able to successfully commercialize its
current   or    future   products    in    any   international    market.    See
"Business--Marketing, Sales and Distribution."
 
                                       12
<PAGE>
Risk of Market Withdrawal or Product Recall
 
    The  Company's  products are  complex devices  designed  for use  inside and
around the organs of  the female reproductive system.  To date, the Company  has
only  limited experience regarding the reliability of its products in the field.
Component failures, manufacturing errors  or design defects  could result in  an
unsafe  condition or injury to the patient. If any such failures or defects were
material, the Company  could be  required to  undertake a  market withdrawal  or
recall  of products. Even if regulatory approvals  are obtained, there can be no
assurance that a market withdrawal or product recall will not occur. Costs of  a
market  withdrawal  or product  recall  could be  significant  and could  have a
material adverse  effect  on the  Company's  business, financial  condition  and
results of operations. See "Business--Manufacturing."
 
Possible Future Capital Requirements; Risks Associated with Potential
Acquisitions
 
    The Company's capital requirements depend on numerous factors, including the
extent  to which the Company's products gain market acceptance, actions relating
to  regulatory  and   reimbursement  matters,  progress   of  clinical   trials,
introduction  of alternative  means for  microlaparoscopy, microhysteroscopy and
fallopian  tube  visualization  by  competitors  of  the  Company,  pricing   of
competitive products, the cost and effect of promotional discounts and marketing
programs  in which  the Company  may be  required to  engage, the  resources the
Company devotes to  marketing, manufacturing  and developing  its products,  and
other  factors.  The  timing  and amount  of  such  capital  requirements cannot
accurately  be  predicted.  Consequently,  although  the  Company  believes  the
proceeds  from this Offering,  together with cash  generated from revenues, will
provide adequate funding for its capital requirements through 1997, there can be
no assurance that the Company will  not require additional funding or that  such
additional  funding, if needed,  will be available on  terms satisfactory to the
Company, or  at  all.  Any  additional  equity  financing  may  be  dilutive  to
stockholders,   and  debt  financing,  if  available,  may  involve  restrictive
covenants. Failure to raise  capital when needed could  have a material  adverse
effect on the Company's business, financial condition and results of operations.
See  "Use of  Proceeds" and "Management's  Discussion and  Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
    The Company may make acquisitions in  the future, and the Company  regularly
evaluates   such  opportunities.  Product  and  technology  acquisitions  entail
numerous  risks,  including  difficulties   in  the  assimilation  of   acquired
operations  and products, diversion of  management's attention to other business
concerns, amortization of acquired intangible  assets and potential loss of  key
employees  of acquired companies. The Company  has no experience in assimilating
acquired organizations and  products into  its operations. No  assurance can  be
given as to the ability of the Company to integrate successfully any operations,
personnel  or products that might be acquired  in the future, and the failure of
the Company to  do so  could have  a material  adverse effect  on the  Company's
business, financial condition and results of operations. See "Use of Proceeds."
 
Uncertainty Relating to New Product Development
 
    The  Company's strategy involves the design and development of new products.
In microlaparoscopy,  the Company  is developing  new electrocautery  and  other
microsurgical  instruments.  Enhancements  under development  for  the Company's
microhysteroscopy   technology    include    microhysteroscopic    biopsy    and
electrocautery   devices.  In   addition,  Imagyn  is   directing  research  and
development efforts toward perfecting and enhancing its proprietary micro-access
technology for both microhysteroscopy and microlaparoscopy. The Company is  also
developing  new  applications  for  its  proprietary  linear  everting  catheter
technology. The product  development process is  time-consuming and costly,  and
there  can  be  no  assurance  that  product  development  will  be successfully
completed, that necessary regulatory approvals or clearances will be granted  by
the  FDA on a  timely basis, or at  all, or that any  new products developed and
introduced by the Company will achieve market acceptance. Failure by the Company
to  develop,  obtain  necessary  regulatory  clearances  or  approvals  for,  or
successfully  market, new products  could have a material  adverse effect on the
Company's  business,  financial  condition   and  results  of  operations.   See
"Business--Research and Development."
 
Product Liability Risk; Limited Insurance Coverage
 
    The  development, manufacture and sale of medical devices entail significant
risk of product liability claims and device failures. There can be no  assurance
that  the Company's existing  insurance coverage limits  are adequate to protect
the Company from any liabilities it might incur in connection with the  clinical
trials or sales of its
 
                                       13
<PAGE>
products.  In  addition, the  Company  may require  increased  product liability
coverage if 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 "Business--Product Liability and Insurance."
 
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.
See "Business--Employees" and "Management."
 
Broad Discretion of Management to Allocate Offering Proceeds
 
    The  Company expects  that the  proceeds of this  Offering will  be used for
development activities  and  expansion  of marketing,  sales  and  manufacturing
activities  for the MicroLap  system, the MicroSpan  system, the Ovation systems
and other products, working capital and general corporate purposes. The  Company
is  not currently able to  estimate the allocation of  proceeds among such uses,
and the timing  and amount  of expenditures  will vary  depending upon  numerous
factors.  The Company's  management will have  broad discretion  to allocate the
proceeds of this Offering and to determine the timing of expenditures. See  "Use
of Proceeds."
 
Possible 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. These broad market  fluctuations may adversely affect the
market price of the Company's Common Stock. In addition, the market price of the
shares of  Common  Stock  is likely  to  be  highly volatile.  Factors  such  as
fluctuations  in the Company's results of operations, failure of such results of
operations to meet  the expectations  of public market  analysts and  investors,
announcements of technological innovations or new products by the Company or its
competitors,  FDA and international regulatory  actions, actions with respect to
reimbursement matters,  developments  with  respect to  patents  or  proprietary
rights,  public concern as to the safety of products developed by the Company or
others, changes in health care policy in the United States and  internationally,
changes  in stock  market analyst  recommendations regarding  the Company, other
medical device companies or the  medical device industry generally, and  general
market  conditions may have a significant adverse  effect on the market price of
the Common  Stock. In  addition, it  is likely  that during  a future  quarterly
period,  the Company's results of operations  will fail to meet the expectations
of stock market analysts and investors  and, in such event, the Company's  stock
price could be materially and adversely effected.
 
Control by Directors, Executive Officers and Affiliated Entities
 
    The  Company's directors,  executive officers  and entities  affiliated with
them will, in the aggregate, beneficially own approximately 39% of the Company's
outstanding Common  Stock  following  the completion  of  this  Offering.  These
stockholders,  if acting  together, would be  able to  control substantially all
matters requiring approval  by the  stockholders of the  Company, including  the
election  of directors and the approval of mergers or other business combination
transactions. Such concentration of ownership could prevent a change in  control
of the Company. See "Principal Stockholders."
 
No Prior Public Trading Market
 
    Prior  to this  Offering, there  has been  no public  market for  the Common
Stock, and there can be no assurance that an active trading market will  develop
or, if one does develop, that it will be maintained. The initial public offering
price,  which  was  established  by negotiations  between  the  Company  and the
Underwriters, may not be indicative of  prices that will prevail in the  trading
market. See "Underwriting."
 
                                       14
<PAGE>
Possible Anti-Takeover Effect of Certain Charter and Bylaw Provisions
 
    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. These
provisions 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. In addition, the Company has not elected to be excluded from the
provisions of Section 203 of the Delaware General Corporation Law, which imposes
certain  limitations  on  transactions  between  a  corporation  and "interested
stockholders," as defined in such  provision. See "Management" and  "Description
of Capital Stock."
 
Shares Eligible for Future Sale and Potential Adverse Effect on Market Price
 
    Sales  of  Common  Stock  (including  shares  issued  upon  the  exercise of
outstanding options) in the public  market after this Offering could  materially
adversely  affect the market  price of the  Common Stock. Such  sales also might
make  it  more  difficult  for  the   Company  to  sell  equity  securities   or
equity-related  securities in the  future at a  time and price  that the Company
deems appropriate. Upon the completion of  this Offering, the Company will  have
7,244,155  shares of Common  Stock outstanding, assuming  no exercise of options
after April 1, 1996. Of these outstanding shares of Common Stock, the  2,500,000
shares  sold in this Offering will  be freely tradable without restriction under
the Securities Act,  unless purchased by  "affiliates" of the  Company, as  that
term  is defined in Rule  144 under the Securities  Act. The remaining 4,744,155
shares of Common Stock held by existing stockholders are "restricted securities"
as that term is defined  in Rule 144 under the  Securities Act, and were  issued
and  sold  by  the  Company  in reliance  on  exemptions  from  the registration
requirements of  the Securities  Act. These  shares may  be sold  in the  public
market only if registered or pursuant to an exemption from registration, such as
Rule  144, Rule  144(k) or  Rule 701  under the  Securities Act.  All holders of
Common Stock  and options  to  purchase Common  Stock  have agreed  pursuant  to
certain  lock-up agreements  that they will  not offer, sell,  contract to sell,
grant any option to  sell or otherwise dispose  of, directly or indirectly,  any
shares  of Common Stock owned by them or that could be purchased by them through
the exercise of options to purchase Common Stock for a period of 180 days  after
the  date of this Prospectus without the prior written consent of Dillon, Read &
Co. Inc. Upon expiration of the lock-up agreements, approximately 713,811 shares
of Common Stock held by existing stockholders will be eligible for sale  without
restriction  pursuant to  Rule 144(k) or  Rule 701,  and approximately 1,020,112
shares held by existing  stockholders will be eligible  for sale subject to  the
volume  and other restrictions of Rule  144. The remaining 3,010,232 shares held
by existing stockholders will become eligible for sale pursuant to Rule 144 upon
the expiration of their two-year holding  periods. As of April 1, 1996,  665,059
shares  were subject to outstanding options. All  of these shares are subject to
the lock-up  agreements described  above. Upon  the expiration  of such  lock-up
agreements,  244,168 shares subject to such options will be vested. 4,102,223 of
the shares outstanding  immediately following  the completion  of this  Offering
will  be  entitled  to registration  rights  with  respect to  such  shares upon
termination of  lock-up agreements.  The number  of shares  sold in  the  public
market  could increase if registration rights are exercised. See "Description of
Capital Stock--Registration Rights" and "Shares Eligible for Future Sale."
 
Dilution
 
    The initial  public offering  price  is substantially  higher than  the  net
tangible  book value per  share of Common Stock.  Investors purchasing shares of
Common Stock in this Offering will therefore incur immediate and substantial net
tangible book value dilution. See "Dilution."
 
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.  See "Dividend
Policy."

                                  THE COMPANY
 
    Imagyn was  incorporated  in  California  in  August  1989  to  advance  the
development  of gynecological applications of novel catheter technology licensed
by the  Company from  Baxter  Healthcare Corporation  ("Baxter") and  Thomas  J.
Fogarty, M.D. ("Fogarty"). In mid-1994, the Company was repositioned to focus on
the  development of a broad range of products for gynecological and reproductive
disorders based on its proprietary  technology. The Company anticipates that  it
will  reincorporate in Delaware prior to the completion of this Offering. Unless
the context otherwise requires,  references in this  Prospectus to "Imagyn"  and
the  "Company" refer to Imagyn Medical,  Inc., a Delaware corporation, and where
applicable, its  predecessor corporation,  Imagyn  Medical, Inc.,  a  California
corporation,  and  its  subsidiary,  Imagyn  International,  Inc.  The Company's
principal executive offices  are located at  27651 La Paz  Road, Laguna  Niguel,
California 92677. Its telephone number is (714) 362-2500.
 
                                USE OF PROCEEDS
 
    The  net proceeds to  the Company from  the sale of  the 2,500,000 shares of
Common Stock  offered  hereby  are estimated  to  be  approximately  $27,100,000
($31,285,000  if the Underwriters' over-allotment  option is exercised in full),
at an assumed initial public offering price of $12.00 per share, after deducting
the underwriting discounts and commissions and estimated offering expenses.
 
    The Company estimates that  approximately $7.0 million  of the net  proceeds
will  be  used  to  fund  product  introduction,  build  a  sales  and marketing
organization and develop and sponsor physician training programs,  approximately
$5.0  million will be  used for research  and development of  current and future
products including clinical trials, approximately $1.5 million will be used  for
capital  equipment purchases and that the remainder  of the net proceeds will be
used for working capital and general corporate purposes. The foregoing represent
estimates only,  and management  of the  Company does  not have  specific  plans
regarding   the  precise  allocation  of   the  Offering  proceeds  among  these
anticipated uses. The actual amounts expended by the Company for these  purposes
and  the timing of such expenditures  will depend on numerous factors, including
the status of the Company's development efforts, actions relating to  regulatory
matters,  the extent to which the  Company's products gain market acceptance and
competition. The  Company may  use a  portion  of the  net proceeds  to  acquire
complementary   businesses,  products  or  technologies.  Although  the  Company
currently  has  no   agreements  to   acquire  such   businesses,  products   or
technologies,  the Company has  in the past  and expects to  continue to discuss
such opportunities  with  interested  third  parties. Pending  use  of  the  net
proceeds  of this  Offering, the  Company plans  to invest  the net  proceeds in
interest-bearing, investment  grade securities.  Although the  Company  believes
that  the net proceeds from  this Offering together with  existing cash and cash
equivalents will be sufficient  to maintain its  current and planned  operations
through  the end of  1997, there can be  no assurance that  the Company will not
require  additional  financing  within   this  time  frame.  See   "Management's
Discussion    and   Analysis    of   Financial   Condition    and   Results   of
Operations--Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
    The Company has  never declared or  paid any cash  dividends on its  capital
stock.  The Company currently intends to  retain any future earnings for funding
growth and, therefore,  does not  anticipate paying  any cash  dividends in  the
foreseeable future.

    The following table sets forth the capitalization of the Company as of March
31,  1996 (i) on a pro forma basis to give effect to the filing of the Company's
Restated Certificate  of Incorporation  to  authorize 5,000,000  and  50,000,000
shares  of Preferred  Stock and Common  Stock, respectively, and  to reflect the
conversion of  all outstanding  shares  of the  Company's Preferred  Stock  into
Common  Stock upon the closing of this  Offering and (ii) as adjusted to reflect
the sale of the 2,500,000  shares of Common Stock  offered hereby at an  assumed
initial  public  offering price  of  $12.00 per  share  and after  deducting the
estimated underwriting discounts and commissions and estimated offering expenses
payable by the Company.

                                    DILUTION
 
    The  pro forma net tangible  book value of the Common  Stock as of March 31,
1996 was $8,402,722, or  approximately $1.77 per share.  Pro forma net  tangible
book  value  per share  represents the  amount of  the Company's  total tangible
assets less total  liabilities, divided  by the pro  forma number  of shares  of
Common  Stock outstanding. Net tangible book value dilution per share represents
the difference between  the amount  per share paid  by purchasers  of shares  of
Common  Stock in  this Offering  and the  net tangible  book value  per share of
Common Stock immediately after completion of this Offering. After giving  effect
to  the sale  by the  Company of  the 2,500,000  shares of  Common Stock offered
hereby at an assumed initial public offering price of $12.00 per share and after
deducting the  estimated underwriting  discounts and  commissions and  estimated
offering  expenses payable by the Company, the pro forma net tangible book value
of  the  Company  as  of  March  31,  1996  would  have  been  $35,502,722,   or
approximately  $4.90 per  share. This  represents an  immediate increase  in net
tangible book value of $3.13 per share to existing stockholders and an immediate
dilution in net tangible book value of $7.10 per share to new investors in  this
Offering.
 
    The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The  following  discussion  of  the  financial  condition  and  results   of
operations  of the Company  should be read in  conjunction with the Consolidated
Financial Statements and the  related Notes thereto  included elsewhere in  this
Prospectus.  The  following Management's  Discussion  and Analysis  of Financial
Condition and  Results of  Operations contains  forward-looking statements  that
involve  risks  and uncertainties.  The Company's  actual results  of operations
could  differ  materially  from   those  anticipated  in  such   forward-looking
statements  as a result  of certain factors  set forth under  "Risk Factors" and
elsewhere in this Prospectus.
 
Background
 
    Imagyn was  formed  in 1989  to  advance the  development  of  gynecological
applications  of novel catheter  technology licensed by  the Company from Baxter
and Fogarty. In 1992, the Company commenced commercial shipments of its  Ovation
systems,  based on this technology, to  international distributors for resale to
physicians  and  hospitals.   During  1992  and   1993,  the  Company   required
distributors to make substantial initial purchases of Ovation systems in lieu of
payment  of  distribution fees  for exclusivity  in  specific territories.  As a
result, sales in 1992 and  1993 were not representative  of the actual level  of
sales  to  physicians and  hospitals in  these  markets. In  1994 and  1995, the
Company realigned its international distribution  for the Ovation systems.  This
realignment  involved both  a reduction  in the  number of  distributors and the
establishment of direct sales activities  through a limited number of  employees
and  agents in the Company's most important markets, the United Kingdom, Germany
and Australia.
 
    In November 1992, the Company entered into an agreement with Terumo for  the
sale  and licensed  manufacture of the  Ovation systems in  Japan. In connection
with the granting of the distribution  and license rights under this  agreement,
Terumo  paid the Company distribution and license fees aggregating $2.1 million.
Based on the Company's  continuing obligations under  the agreement to  transfer
manufacturing  know-how for the  Ovation systems to Terumo,  the license fees of
$1.0 million have been treated as deferred income until such time as the Company
completes the transfer of the manufacturing know-how pursuant to the  agreement.
The  Company is required to  complete such transfer by  August 1997, after which
the Company will receive royalties on  product sales by Terumo. During 1993  and
1994,  Terumo conducted clinical  trials in Japan for  the purpose of supporting
regulatory  and   reimbursement   approvals   for  the   Ovation   system.   See
"Business--Strategic Marketing Alliances."
 
    In  January  1994,  the  Company  was  notified  by  the  FDA  that  its PMA
application for the Ovation falloposcopy system submitted to the FDA in May 1992
was deficient in certain  respects, particularly with respect  to the design  of
the  clinical study, which was not structured as a controlled, randomized study,
and the breadth of the Company's visualization claims. The Company attempted  to
address  the FDA's  concerns by providing  a reevaluation of  its clinical data;
however, the FDA did not find  this analysis acceptable and, in September  1995,
the Company withdrew this PMA application.
 
    Due  in part to the regulatory concerns  relating to the PMA application for
the Ovation  falloposcopy system,  the Board  of Directors  determined that  the
Company  needed to be repositioned to focus  on the development of a broad range
of  products  for  gynecological  and   reproductive  disorders  based  on   its
proprietary  technology.  In  October  1994,  Franklin  D.  Brown  was  hired as
President and Chief Executive  Officer to lead the  repositioning effort and  to
formulate  a  new strategy.  During 1995,  the Company  sought new  financing to
implement this repositioning  effort, including the  advancement of  development
efforts  to broaden the  Company's product line. In  September 1995, the Company
completed an  equity recapitalization  which included  a reverse  1-for-5  stock
split  of  all outstanding  stock, the  conversion of  all Preferred  Stock into
Common Stock, and the sale of $9.9  million of new Preferred Stock. The  Company
has  since received FDA approval of an  IDE for a new multicenter clinical trial
for the  Ovation  falloposcopy system  in  diagnosing the  presence  of  blocked
fallopian tubes in infertile women. This clinical study is currently underway.
 
    In  1994, the  Company commenced  international commercial  shipments of the
initial product in its broadened product line, the MicroLap system. By  February
1995,  the Company  had received  three FDA  510(k) clearances  for the MicroLap
system, after which  the Company commenced  marketing the system  in the  United
States.  The Company engaged  the services of  non-stocking sales representative
organizations to promote sales of the MicroLap system.

    In 1995, the Company  received FDA 510(k) clearance  for use of the  Ovation
intrauterine  insemination system  and several additional  510(k) clearances for
other indications for the MicroLap system. The Company also began evaluating use
of its micro-optics and micro-access technologies in a microhysteroscopy system.
In August 1995, Terumo  received Japanese regulatory  approval for marketing  of
the  Ovation  tubal  recanalization  system.  Following  this  approval,  Terumo
commenced planning for  the 1996  commercial introduction of  the Ovation  tubal
recanalization  system  in  Japan.  Terumo  has applied  for,  but  has  not yet
obtained, Japanese reimbursement approval.
 
    In October 1995, the Company entered into a distribution agreement with USSC
pursuant to which USSC was granted exclusive international marketing rights  for
the  MicroLap system in  all international markets  (excluding China and India).
USSC was  also granted,  on a  co-exclusive basis  with the  Company,  marketing
rights to the MicroLap system in the United States. As a result of the agreement
with USSC, the Company has initiated the termination of all of its international
distributors for the MicroLap system and, in connection with these terminations,
the  Company  made  certain payments  to  these distributors.  In  addition, the
Company  reached  agreement  with  all  of  its  previous  sales  representative
organizations  in the United  States for the termination  of their activities in
connection with the  marketing of the  MicroLap system and,  in connection  with
these agreements, made certain termination-related payments. Following execution
of  the  agreement with  USSC, the  Company  began increasing  its manufacturing
capacity to support USSC's introduction of  the MicroLap system and, in  January
1996, the Company completed training of certain USSC sales personnel.
 
    The  Company manufactures  the Ovation systems  and certain  of its MicroLap
system products,  including its  proprietary microlaparoscope  and  micro-access
devices,  at  its  manufacturing  facilities and  has  only  recently  begun the
manufacture of these products in commercial quantities. The Company has  limited
manufacturing  capacity  and  will be  required  to increase  both  its in-house
manufacturing capability and the size of its manufacturing facilities.  Although
the  Company has leased the space which  it will use to expand its manufacturing
facilities, there can be no assurance that the Company will be able to  complete
its  facility  expansion,  attract,  train and  retain  the  required personnel,
including personnel skilled in micro-optics assembly processes, or increase  its
manufacturing  capability  and capacity  in  a timely  manner.  There can  be no
assurance  that  reliable,  high-volume  manufacturing  can  be  established  or
maintained at commercially reasonable costs on a timely basis, or at all. If the
Company   is  unable  to  increase  its  in-house  manufacturing  capability  or
successfully complete the expansion of its manufacturing facilities in a  timely
manner,  the Company may need to  obtain alternative manufacturing facilities or
to establish contract manufacturing for its products. Delays associated with, or
inability to establish, such  capacity could have a  material adverse affect  on
the  Company's  business, financial  condition  and results  of  operations. The
Company currently obtains certain components of its product systems from  single
source  suppliers. These  components include the  optic image fiber  used in the
MicroLap, a similar version of which will also be used in the MicroSpan, and the
medical video camera and light source used in connection with the Ovation  tubal
recanalization  system.  There can  be no  assurance that  the Company  will not
encounter  future  component  shortages  or  other  disruptions  in  supply   of
materials.  Delays  associated  with  any  future  raw  materials  or  component
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.
 
    Future revenues and results of  operations may fluctuate significantly  from
quarter  to quarter  and will  depend upon, among  other factors,  the extent to
which the Company's products  gain market acceptance, the  timing and volume  of
orders  from USSC,  Terumo, other  international distributors  and the Company's
other customers,  actions  relating  to regulatory  and  reimbursement  matters,
progress   of   clinical   trials,  introduction   of   alternative   means  for
microlaparoscopy,  microhysteroscopy   and  fallopian   tube  visualization   by
competitors of the Company, pricing of competitive products, the cost and effect
of  promotional discounts  and marketing  programs in  which the  Company may be
required to engage and the absence of a backlog of orders. Results of operations
will also depend  upon the amount  of royalties payable  under the license  from
Baxter  and Fogarty relating to the  linear everting catheter technology used in
the Ovation systems.  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 two years as the Company continues to
expend substantial resources to expand its marketing and sales activities in the
United States, fund clinical trials  in support of regulatory and  reimbursement
approvals,  and  fund  research  and development  and  the  introduction  of new
products.

Results of Operations
 
THREE MONTHS ENDED MARCH 31, 1996 AND 1995
 
    NET SALES.  Net sales for the three months ended March 31, 1996 increased to
$1.5 million  from $335,000  for the  three  months ended  March 31,  1995.  The
increase  was primarily the result of MicroLap  system sales to USSC. There were
no sales to USSC  during the three  months ended March 31,  1995. For the  three
months  ended March 31,  1996, 7% of  the Company's sales  were to international
customers; for the three months ended March 31, 1995, 91% of the Company's sales
were to international customers. The decrease in the percentage of the Company's
sales to international  customers is  primarily the  result of  the increase  in
United   States  sales  and  the  termination  of  the  Company's  international
distributors for the MicroLap system. The  Company records all sales to USSC  as
domestic sales; however, sales of the Company's products by USSC are expected to
include  sales  to  international  customers made  through  Autosuture,  Inc., a
subsidiary of USSC.
 
    COST OF SALES.   Cost of  sales for the  three months ended  March 31,  1996
increased  to $1.2 million  from $265,000 for  the three months  ended March 31,
1995. The increase was attributable  to the increase in  sales as well as  costs
associated  with  increased manufacturing  support  expenditures. Cost  of sales
during the  three  months  ended  March 31,  1996  also  included  non-recurring
production  costs  and inefficiencies  associated  with the  rapid  increase and
expansion of  production  operations  at  the  Company's  current  manufacturing
facilities.  As a result  of these costs and  expenditures, the Company believes
that gross profit margins  for the three  months ended March  31, 1996 were  not
representative  of the  gross profit  margins that  would be  anticipated by the
Company at similar sales levels.
 
    SALES AND MARKETING.   Sales  and marketing  expenses for  the three  months
ended  March 31, 1996 increased  to $746,000 from $459,000  for the three months
ended March 31, 1995. The increase was primarily associated with the increase in
the number  of the  Company's  marketing and  sales  personnel and  in  customer
support expenses.
 
    RESEARCH  AND DEVELOPMENT.  Research and  development expenses for the three
months ended March 31,  1996 increased to $740,000  from $403,000 for the  three
months  ended  March  31,  1995. This  increase  was  attributable  to increased
expenditures for product development and enhancements and costs associated  with
clinical trials of the Ovation falloposcopy system in the United States.
 
    GENERAL  AND ADMINISTRATIVE.   General  and administrative  expenses for the
three months ended March  31, 1996 increased to  $446,000 from $274,000 for  the
three  months ended March  31, 1995. The increase  was primarily associated with
the hiring of  additional personnel  and the amortization  of non-cash  deferred
compensation charges associated with grants of stock options to employees. There
was  no amortization  of deferred compensation  charges during  the three months
ended March 31, 1995.
 
    INTEREST INCOME (EXPENSE), NET.   Net interest income  for the three  months
ended  March 31, 1996  increased to $120,000  from $16,000 for  the three months
ended March  31, 1995.  This increase  was attributable  to interest  earned  on
higher cash balances held by the Company during the three months ended March 31,
1996.
 
YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
    NET SALES.  Net sales for the year ended December 31, 1995 increased to $2.2
million from $1.0 million for the year ended December 31, 1994. The increase was
primarily  the result of the commencement of  sales in the United States in 1995
of  the  MicroLap  system,  increase  of  sales  of  the  MicroLap  systems   in
international  markets and the initial sales of the Company's Ovation systems to
Terumo. In 1995, sales to Terumo  were approximately 25% of the Company's  total
sales.  These sales  included products  purchased by  Terumo in  anticipation of
their 1996  commercial  introduction  in  Japan. Sales  to  USSC  in  1995  were
approximately  11% of the Company's  total sales. In 1995,  72% of the Company's
sales were to international customers; in  1994, virtually all of the  Company's
sales were to international customers. Net sales for the year ended December 31,
1994  of $1.0 million were approximately equal  to the $1.0 million for the year
ended December  31, 1993,  primarily due  to the  substantial purchases  of  the
Company's products made by international distributors in 1993.
 
    COST  OF SALES.  Cost of sales increased  to $1.8 million for the year ended
December 31, 1995 from $1.3  million for the year  ended December 31, 1994.  The
increase  was  attributable  to the  increase  in  the volume  of  sales  of the
Company's products  as  well as  to  costs associated  with  the hiring  of  ten
additional  manufacturing  personnel,  expansion of  manufacturing  and assembly
operations  and  engineering  and  manufacturing  support  functions.  Cost   of
 
                                       22
<PAGE>
sales  for the year ended December 31,  1994 increased to $1.3 million from $1.0
million for  the  year ended  December  31, 1993,  primarily  as the  result  of
$298,000  in reserves  for inventory obsolescence.  Cost of sales  for the years
ended December  31, 1995,  1994 and  1993 included  $225,000, $298,000  and  $0,
respectively, in reserves for inventory obsolescence.
 
    SALES AND MARKETING.  Sales and marketing expenses increased to $3.3 million
for  the  year ended  December 31,  1995 from  $2.3 million  for the  year ended
December 31,  1994.  The increase  was  primarily  due to  sales  and  marketing
expenses  associated with the introduction of the Company's MicroLap products in
the United States, including expenses of $418,000 associated with termination of
international distributors  and  United  States sales  representatives  for  the
MicroLap  system  in connection  with the  USSC  agreement. Sales  and marketing
expenses of $2.3 million for the year ended December 31, 1994 were approximately
equal to the $2.4 million for the year ended December 31, 1993.
 
    RESEARCH AND DEVELOPMENT.  Research and development ("R&D") expenses,  which
include  clinical and  regulatory expenses, of  $1.8 million for  the year ended
December 31, 1995  were approximately  equal to the  $1.8 million  for the  year
ended  December  31, 1994.  R&D  expenses of  $1.8  million for  the  year ended
December 31, 1994  were approximately  equal to the  $1.9 million  for the  year
ended  December 31,  1993. The  Company anticipates  that R&D  expenditures will
increase in  the next  several years  to support  development of  new  products,
clinical  trials of the Ovation falloposcopy system under the Company's recently
approved IDE and other clinical and regulatory activities.
 
    GENERAL AND ADMINISTRATIVE.   General and administrative expenses  increased
to  $1.3 million for the year ended December  31, 1995 from $1.1 million for the
year ended  December 31,  1994. The  increase was  primarily the  result of  the
amortization of non-cash deferred compensation charges associated with grants of
stock  options to  employees. General  and administrative  expenses increased to
$1.1 million for the  year ended December  31, 1994 from  $904,000 for the  year
ended  December  31,  1993.  This  increase  primarily  resulted  from  expenses
associated with recruiting and hiring a new Chief Executive Officer.
 
    OTHER OPERATING INCOME.  Other operating income of $3.5 million for the year
ended December 31, 1995 resulted  from nonrecurring payments in connection  with
various  marketing rights for certain products. There was no such income for the
years ended December 31, 1994 and 1993.
 
    INTEREST INCOME (EXPENSE), NET.  Net  interest expense was $217,000 for  the
year ended December 31, 1995, as compared to interest income of $175,000 for the
year ended December 31, 1994. The interest expense was primarily attributable to
interest  incurred  by  the  Company  on short  term  notes  payable  issued and
converted into Preferred Stock in 1995. Interest income (expense), net decreased
to $175,000 for  the year ended  December 31,  1994 from $337,000  for the  year
ended  December  31, 1993.  The decrease  was attributable  to the  reduction of
Company's cash balances and interest earned thereon.
 
Income Taxes
 
    The Company has not generated any  taxable income to date and therefore  has
not  paid any federal income taxes since its inception. The Company accounts for
income taxes under  Statement of  Financial Accounting Standards  No. 109  ("FAS
109").  Realization of deferred  tax assets is dependent  on future earnings, if
any, the  timing  and amount  of  which are  uncertain.  Accordingly,  valuation
allowances,  in amounts equal to the net  deferred tax assets as of December 31,
1995  and  1994,  have  been  established  in  each  period  to  reflect   these
uncertainties.
 
    At  December 31, 1995, the Company had  federal and state net operating loss
carryforwards of $12.4 million and  $5.9 million, respectively, and federal  and
state   research  and  experimentation  credit  carryforwards  of  $560,000  and
$220,000, respectively,  that will  expire at  various dates  beginning in  1997
through  2010, if not utilized. Utilization of net operating loss and tax credit
carryforwards will be  subject to  a substantial  annual limitation  due to  the
ownership  change limitations of the Internal  Revenue Code of 1986, as amended,
and similar state provisions. The annual  limitation is likely to result in  the
expiration  of  most  of  the  Company's  net  operating  loss  and  tax  credit
carryforwards before  full  utilization  as  a  result  of  the  September  1995
recapitalization.
 
Liquidity and Capital Resources
 
    Since  inception, the Company's expenses have significantly exceeded its net
sales, resulting in  an accumulated  deficit of $22.1  million as  of March  31,
1996.  The  Company  has  funded its  operations  since  incorporation primarily
through the private placement of  equity securities and other operating  income.
Through March 31, 1996, the
 
                                       23
<PAGE>
Company   had  raised  $30.3  million  from  the  private  placement  of  equity
securities, of which  $9.9 million was  raised in the  Company's September  1995
recapitalization.  Through March 31, 1996, the Company had received $5.6 million
in fees relating to two distribution agreements.
 
    At March 31, 1996, the Company's principal source of liquidity consisted  of
cash,  cash equivalents and short-term investments of $7.8 million. Cash used in
the Company's operations increased  to $1.5 million for  the three months  ended
March 31, 1996 from $1.2 million for the three months ended March 31, 1995. This
increase was primarily due to an increase in accounts receivable for the period.
Cash  used in the  Company's operations decreased  to $2.2 million  for the year
ended December 31, 1995 from $5.1 million for the year ended December 31,  1994.
This  decrease was due to the receipt  of $3.5 million of other operating income
in 1995,  which  was  offset  by increased  sales  and  marketing  expenses  and
increased  working  capital  requirements.  The  Company's  capital expenditures
during the year ended  December 31, 1995  and the three  months ended March  31,
1996  were  $163,000 and  $92,000,  respectively. The  Company  anticipates that
capital expenditures will  increase in  1996 due to  expansion of  manufacturing
operations  and facilities.  The Company  intends to  finance its  capital needs
principally from the net proceeds of this Offering and interest thereon, and its
existing capital resources.  The Company  has not  sought to  obtain any  credit
facilities to provide additional working capital.
 
    Imagyn  believes  that  the  anticipated  net  proceeds  from  this Offering
together with interest thereon and the Company's existing capital resources will
be sufficient to fund its operations through 1997. However, the Company's future
liquidity and capital  requirements will depend  on numerous factors,  including
the  extent  to which  the Company's  products  gain market  acceptance, actions
relating to regulatory and reimbursement  matters, progress of clinical  trials,
introduction  of alternative  means for  microlaparoscopy, microhysteroscopy and
fallopian  tube  visualization  by  competitors  of  the  Company,  pricing   of
competitive products, the cost and effect of promotional discounts and marketing
programs  in which the Company may be  required to engage and the resources that
the Company devotes to marketing, manufacturing and developing its products. The
Company's capital  requirements will  also depend  on, among  other things,  the
resources required to hire and develop a direct sales force in the United States
and  the  resources required  to  expand manufacturing  capacity  and facilities
requirements. Accordingly, there can be no  assurance that the Company will  not
require  additional financing within this time  frame. There can be no assurance
that additional funding, if needed, will  be available on terms satisfactory  to
the  Company, or  at all.  Any additional  equity financing  may be  dilutive to
stockholders,  and  debt  financing,  if  available,  may  involve   restrictive
covenants.  Failure to raise  capital when needed could  have a material adverse
affect on the  business, financial condition  and results of  operations of  the
Company.

                                    BUSINESS
 
    Imagyn  designs, develops and markets micro-invasive, cost-effective devices
for diagnosis and  treatment of  gynecological and  reproductive disorders.  The
Company's proprietary technology platform based on micro-optics and micro-access
devices  provides  physicians  with  the ability  to  atraumatically  access and
visualize the abdominal  cavity, the  uterus and the  fallopian tubes.  Imagyn's
proprietary  micro-optics enable  physicians to  visualize a  patient's internal
anatomy with  the  resolution and  light  efficiency of  larger,  more  invasive
devices  commonly  used  today.  Imagyn's  proprietary,  disposable micro-access
devices enable physicians  to perform  certain procedures  outside the  hospital
without the need for general anesthesia. The Company's principal product systems
based  on these core technologies are  the MicroLap microlaparoscopy system, the
MicroSpan microhysteroscopy  system  and  the Ovation  systems  for  infertility
indications.  Compared to traditional procedures,  the Company's product systems
facilitate earlier definitive diagnosis  and treatment, significantly lower  the
procedure  cost  associated  with  more  invasive  surgery  and  reduce  patient
discomfort, recovery time and morbidity. To date, the Company has sold over  850
MicroLap  microlaparoscopes  and  over 6,000  Ovation  catheters.  An additional
approximately 150 MicroLap microlaparoscopes  have been shipped to  distributors
for  use  as demonstration  units  in connection  with  the introduction  of the
MicroLap system, and  an additional approximately  2,000 Ovation catheters  have
been   shipped  for  use  in  connection   with  clinical  studies  and  product
evaluations.
 
    Imagyn's diagnostic and operative  micro-invasive product systems address  a
broad  continuum of gynecological  and reproductive disorders  affecting a large
number of women, including pelvic  pain, uterine disorders and infertility,  and
provide  a less invasive procedure for  tubal sterilization. Because of the high
incidence of these  disorders and  the popularity  of tubal  sterilization as  a
contraceptive  method, large markets exist for devices that treat such disorders
and  that   facilitate  tubal   sterilization.   First,  pelvic   pain   affects
approximately 6 million women in the United States and can be caused by a number
of   serious   conditions,   including  endometriosis,   adhesions   and  pelvic
inflammatory disease. Second, uterine disorders affect approximately 25  million
women  in the United States and  may lead to significant complications including
uterine  bleeding,  acute  pain  and  infertility.  Third,  infertility  is   an
increasingly  common  and often  emotionally  traumatic condition  which affects
approximately 5 million women in the United States. Finally, tubal sterilization
is chosen as  a permanent  contraceptive method by  approximately 800,000  women
annually  in the United States.  Despite the large size  of these markets, there
can be no assurance that the Company's product systems will be accepted and will
compete effectively in any of these markets. Market acceptance of the  Company's
product  systems  will  be  dependent  upon,  among  other  things,  physicians'
determinations that the Company's  product systems and  the procedures in  which
they  are intended  to be  used are safe  and effective  alternatives to current
hospital-based procedures and demonstrate clinical utility, and can be used in a
cost-effective manner.
 
    The Company's product systems enable physicians to access and visualize  all
of  the organs of a woman's reproductive system outside the hospital without the
need for general anesthesia. The MicroLap system, which enables the physician to
access the  abdominal  cavity  without  the  need  for  post-operative  sutures,
includes  a  2 millimeter-diameter  microlaparoscope  with resolution  and light
efficiency characteristics which the Company believes are comparable to those of
standard 10 millimeter-diameter laparoscopes. The MicroSpan system  incorporates
a  new, high  resolution microhysteroscope  and a  new uterine  access device to
enable the physician to atraumatically access and visualize the interior of  the
uterus.  The  Microlap and  MicroSpan systems  enable  physicians to  access the
abdominal cavity and the uterus  for treatment with the Company's  microsurgical
instruments.  The  Ovation  systems  are designed  to  enable  the  physician to
atraumatically access, navigate and visualize the entire length of the fallopian
tubes. Imagyn's product systems are designed to offer significant advantages for
physicians, patients and  health care payors.  For physicians, Imagyn's  systems
facilitate improved diagnosis and enhanced practice management. The MicroLap and
MicroSpan systems require limited training for physicians familiar with standard
laparoscopy and hysteroscopy techniques, although more training will be required
for use of the Ovation systems. For patients, Imagyn's systems reduce trauma and
the risk of complications and shorten recovery times as compared to traditional,
more  invasive procedures. For payors, Imagyn's systems can reduce cost, provide
earlier, definitive diagnosis and increase patient satisfaction.

The Female Reproductive System
 
    The female reproductive system includes the uterus, the fallopian tubes  and
the  ovaries. The uterus is a pear-shaped organ connected to the fallopian tubes
and to the vagina. The interior wall of the uterus consists of a layer of  soft,
spongy  tissue called the endometrium. The base  or neck of the uterus is called
the cervix, which serves as the point of  exit and entry from the vagina to  the
uterus.  Under normal conditions, the cervix  is virtually closed (less than one
millimeter in diameter), providing a natural barrier between the vagina and  the
uterus.  Because the cervix is extremely  sensitive, especially to any dilation,
access through the cervix into the  uterine cavity for diagnostic and  operative
procedures can be difficult and extremely painful.
 
    On each side of the uterus is a fallopian tube, which extends outward toward
the  ovaries. The junction  of the uterus  and each fallopian  tube is called an
ostium. The  fallopian tube  is the  channel through  which the  egg enters  the
uterus  during the monthly menstrual cycle. It  is also the conduit for sperm to
reach the egg and  is the site where  fertilization occurs. Fallopian tubes  are
long and narrow, contain many folds, and are fragile and delicate. The fallopian
tubes are lined with epithelial cells whose ciliary motion assists the sperm and
egg  in their migration. Each  fallopian tube is 7-14  centimeters long and only
1-3 millimeters in diameter. The fallopian tubes may become blocked or diseased,
preventing conception.
 
    The diagram below depicts the principal elements of the female  reproductive
system.
 
                    [Diagram of Female Reproductive System]
 
    Disorders  of the female reproductive system include pelvic pain and related
disorders, uterine disorders and infertility.
 
Pelvic Pain and Related Disorders
 
    The prevalence of pelvic pain in  women is widespread, with approximately  7
million  outpatient gynecology visits  annually in the  United States related to
symptoms of pelvic pain. Pelvic pain can often be intense and persistent and can
severely impair  a  woman's health  and  lifestyle.  It is  often  difficult  to
accurately  isolate the location and diagnose the cause of discomfort since many
women with pelvic  pain may suffer  from several disorders  or multiple  disease
sites.  For  example,  scar tissue  from  infection  or prior  surgery  may mask
endometrial lesions which may  lead a physician to  an inaccurate or  incomplete
diagnosis.  Pelvic pain,  in both acute  and chronic  forms, can be  caused by a
number of  serious  conditions  including endometriosis,  adhesions  and  pelvic
inflammatory disease.
 
                                       26
<PAGE>
    Endometriosis,  a common cause of pelvic  pain and also a significant factor
contributing to  infertility,  is  a  disorder  in  which  abnormal  growths  of
endometrial  tissue are present  outside of the  uterus. Endometrial lesions are
usually found on  the reproductive  organs and  adjacent tissues  in the  pelvic
cavity.  It is estimated that  5 million women suffer  from endometriosis in the
United States. Endometriosis is one of the most common gynecological causes  for
hospitalization of women of reproductive age.
 
    Scar   tissue,  or  pelvic  adhesions,  which   can  form  as  a  result  of
endometriosis, infection, prior surgery, hemorrhage or tissue injury, is another
common cause of  pelvic pain. Pelvic  adhesions form in  the healing process  of
more than half of abdominal surgeries. Early intervention after surgery has been
demonstrated  to reduce  the risk  of formation  of dense,  permanent adhesions.
Pelvic adhesions  can  also lead  to  serious long-term  complications  such  as
infertility  and intestinal obstruction. Post-operative  adhesions may affect up
to 2 million women in the United States.
 
    Pelvic inflammatory  disease, another  common  cause of  pelvic pain,  is  a
genital  tract infection  that is often  a complication  of sexually transmitted
diseases. It can cause scarring of the fallopian tubes as the infection  ascends
into  the uterus and tubal structures. In its  most serious form, it can lead to
infertility and ectopic (tubal) pregnancy,  a life-threatening condition. It  is
estimated  that pelvic  inflammatory disease affects  more than  1 million women
each year in the United States.
 
    CURRENT DIAGNOSIS AND TREATMENT
 
    Diagnosis and  identification of  the  cause or  causes  of pelvic  pain  is
difficult.  Since there are currently  no accurate non-invasive diagnostic tests
available, visual  inspection of  the  abdomen and  pelvic  cavity by  means  of
laparoscopic surgery is the current method of choice for diagnosing pelvic pain.
In a traditional laparoscopic surgery procedure, the patient is typically placed
under  general anesthesia. In order to create a space between the abdominal wall
and the  internal  organs  to  facilitate  the  insertion  of  instruments,  the
patient's  abdomen is insufflated,  or inflated, with  a significant quantity of
carbon dioxide gas  delivered through a  specialized needle, known  as a  Veress
needle.  After the patient is properly insufflated, two to three punctures, each
of which  can be  up to  10  millimeters in  diameter, are  made with  a  sharp,
spike-like  device called a trocar. A  cannula, a hollow, sleeve-like device, is
then placed in the  puncture opening. A laparoscope  is placed into the  abdomen
through  one  of the  cannulas  to enable  the  gynecologist to  view  the outer
surfaces of the patient's internal organs. Surgical instruments can be  inserted
through  cannulas  placed  at the  other  trocar puncture  sites.  Following the
procedure, the trocar  sites must  be closed with  sutures and  the patient  may
require significant recovery time due to the effects of the puncture wounds, gas
insufflation  and  general  anesthesia.  Approximately  1  million  laparoscopic
surgeries are performed annually by gynecologists in the United States.
 
    During a traditional laparoscopic surgery procedure, the physician  examines
the internal abdominal organs in an attempt to locate abnormalities which may be
causing  pelvic pain. The  physician may also  use surgical instruments inserted
into the abdomen to treat some abnormalities, such as by removing adhesions,  or
to  biopsy (remove a sample of) tissue for subsequent laboratory evaluation. The
administration of  general  anesthesia  during  the  procedure  complicates  the
determination of the exact cause of pelvic pain because the anesthetized patient
is unable to provide any feedback to the physician.
 
    THE IMAGYN MICROLAP SYSTEM FOR PELVIC PAIN
 
    Imagyn's  proprietary MicroLap system is designed to enable the physician to
perform laparoscopic  procedures  outside  the  hospital.  The  MicroLap  system
includes  the  proprietary MicroLap  microlaparoscope, a  specialized disposable
introducer for placement of  the microlaparoscope into the  abdomen and a  broad
line  of  microsurgical  instruments.  The  2  millimeter-diameter  MicroLap has
resolution and light efficiency characteristics  which the Company believes  are
comparable  to  those  of  standard  10  millimeter-diameter  laparoscopes.  The
MicroLap is attached to  a light source and  medical video camera, allowing  the
physician  to visually  examine the  interior of the  pelvic cavity  in a manner
similar to that of traditional laparoscopic procedures.
 
    In contrast to the traditional  laparoscopic surgery procedure, the  patient
in  a  microlaparoscopic  procedure  is  not  placed  under  general anesthesia.
Instead, sedation and local analgesic protocols  are used to achieve a level  of
sedation  commonly termed "conscious  sedation." An introducer  is inserted into
the patient's abdomen, carrying  the Veress needle and  providing access to  the
abdominal  cavity.  The  patient's  abdomen  is  then  partially  insufflated to
 
                                       27
<PAGE>
permit visualization and the insertion of  instruments, but with a much  smaller
quantity  of carbon  dioxide gas  than is  required in  traditional laparoscopy.
After the patient is  properly insufflated, the Veress  needle is withdrawn  and
the  introducer  is kept  in  place, providing  access  to the  abdominal cavity
without the need for trocar punctures. The MicroLap is then inserted through the
introducer into  the abdomen,  allowing the  physician to  visually examine  the
abdominal organs, in a manner similar to traditional laparoscopy. The small size
of  the MicroLap requires only the very small puncture created by the introducer
to insert the  MicroLap into  the abdomen.  Additional introducer  sites may  be
created for the insertion of microsurgical instruments. Sutures are not required
to  close  these  small  puncture  sites,  significantly  reducing post-surgical
complications due to bleeding and pain  at the puncture sites. This  combination
of  very  small diameter  puncture  sites and  the  reduced requirement  for gas
insufflation enables  microlaparoscopic procedures  to  be performed  using  the
MicroLap  system under conscious sedation  rather than general anesthesia. Using
conscious sedation and the MicroLap system, physicians have been able to perform
a wide  variety of  diagnostic and  operative procedures  in a  surgery  center,
office  or  clinic  at  a  significantly  reduced  cost  and  with  less patient
discomfort and a typical recovery time of approximately one day.
 
    Additionally, because microlaparoscopy does not require general  anesthesia,
the  MicroLap system has enabled the  development of "conscious pain mapping," a
new diagnostic  method  for  pinpointing  the cause  of  pelvic  pain  which  is
performed  while the patient  is awake. Through the  use of microlaparoscopy and
regional anesthesia,  the  physician systematically  probes  the inside  of  the
woman's  pelvis to identify the  exact source and location  of the pain with the
assistance of feedback from  the patient. The  Company believes that  "conscious
pain  mapping"  procedures using  the  MicroLap will  significantly  improve the
diagnosis and treatment of pelvic pain.
 
    Studies indicate that diagnostic laparoscopy procedures performed using  the
MicroLap  system  cost approximately  $1,250, as  compared to  the approximately
$5,000 to $7,000  cost of  a traditional  hospital-based laparoscopic  procedure
performed under general anesthesia.
 
Uterine Disorders
 
    The  uterus is prone to a number  of common disorders including fibroids and
polyps, as  well  as endometrial  cancer,  each of  which  can lead  to  serious
complications   including  abnormal  uterine   bleeding,  significant  pain  and
infertility. Women may  experience one or  more of these  disorders at the  same
time.  Industry sources  estimate that approximately  9% to  14% of menstruating
women experience abnormal  uterine bleeding  that prompts them  to seek  medical
attention  at some  time in  their lives. In  1995, there  were approximately 13
million visits  to gynecologists  for abnormal  uterine bleeding  in the  United
States.
 
    Fibroids,  or benign  muscular tumors, are  among the most  common causes of
abnormal uterine bleeding. Fibroids usually  grow during the reproductive  years
and   can  produce  a  variety  of   problems  including  hemorrhage,  pain  and
infertility. Although  not all  of the  approximately 15  million women  in  the
United  States suffering from fibroids are symptomatic, it is estimated that 35%
to 50% of all women with fibroids have symptoms that are serious enough to  lead
them to seek medical attention.
 
    Polyps,  benign fingerlike protrusions of  tissue extending into the uterine
cavity, are also a common cause  of abnormal uterine bleeding. Approximately  13
million women in the United States develop uterine polyps during their lifetime,
and approximately 25% of these women require medical attention.
 
    Endometrial  cancer may also present initially as abnormal uterine bleeding,
particularly in women  over the  age of 50.  Approximately 31,000  new cases  of
endometrial  cancer  were  reported in  the  United  States in  1994.  Early and
accurate diagnosis is critically important because endometrial cancer can  often
be  cured if detected and treated at  an early stage; however, if undetected and
untreated, endometrial cancer can lead to serious complications or death.
 
    CURRENT DIAGNOSIS AND TREATMENT
 
    Definitive diagnosis of uterine disorders requires direct visual  inspection
of  the  uterine cavity  and  tissue biopsy  of  suspicious areas.  The standard
procedures for  collecting  an adequate  biopsy  sample of  uterine  tissue  for
diagnosis  are dilitation and curettage ("D&C") and hysteroscopy. D&C is a blind
procedure in which the physician dilates the cervix, places a surgical  scraping
device,  known as a curette,  into the uterus and  scrapes the uterine lining to
remove tissue for examination by a pathologist. Because D&C is performed without
visual guidance, it is difficult for the physician to sample the entire  uterine
lining  and,  as  a  result,  significant abnormalities  may  be  missed.  It is
 
                                       28
<PAGE>
estimated that,  in most  cases, approximately  half of  the uterine  cavity  is
actually  sampled and as  many as 30% of  lesions may be  missed. D&C is usually
performed in a hospital  under intravenous sedation  or general anesthesia.  The
procedure  can lead to  a number of  serious complications including hemorrhage,
infection and  perforation and  scarring  of the  uterus. An  estimated  500,000
diagnostic D&C procedures are performed annually in the United States.
 
    The need to visualize the uterus for accurate diagnosis of uterine disorders
led  to  the  development  of  hysteroscopy.  In  traditional  hysteroscopy, the
physician dilates  the  patient's  cervix  and  inserts  a  device  known  as  a
hysteroscope through the cervix into the uterus. The hysteroscope is attached to
a light source and camera allowing the physician to visually examine the uterine
lining. The physician can also introduce surgical instruments through the cervix
to  selectively sample or remove suspicious  lesions. Introducer sheaths used in
current hysteroscopy  procedures, which  accommodate both  the hysteroscope  and
surgical  instruments, range in size from  approximately 5 to 7 millimeters. The
cervical dilation necessitated by  the diameter of these  devices can result  in
significant  pain and discomfort for  the patient. Hysteroscopy has historically
been performed  in  the  hospital under  general  anesthesia.  Industry  sources
estimate  that  approximately  500,000  hysteroscopic  procedures  are performed
annually in the United States.
 
    Current treatments for uterine disorders include various drug therapies  and
surgical  approaches.  Treatment of  uterine bleeding  usually begins  with drug
therapy and, if necessary, proceeds  to more invasive surgical methods.  Current
surgical  procedures for  abnormal uterine  bleeding include  D&C, hysterectomy,
myomectomy  (fibroid  removal  by  open  surgery),  endometrial  resection,  and
endometrial ablation (coagulation of the endometrium).
 
    THE IMAGYN MICROSPAN SYSTEM FOR UTERINE DISORDERS
 
    Imagyn's  diagnostic  and  operative MicroSpan  microhysteroscopy  system is
designed  specifically  for  use  outside   the  hospital.  The  Company's   new
proprietary uterine access device enables the physician to atraumatically access
the  uterus  without  the  need  for  cervical  dilation.  Once  positioned, the
micro-access device, with its very low profile, will permit the simultaneous use
of the microhysteroscope  and the Company's  specialty diagnostic and  operative
microsurgical instruments.
 
    Without  the need for painful  dilation of the cervix  prior to insertion of
the device,  the patient  can  remain comfortable  with only  local  anesthesia.
Microhysteroscopy  can  be performed  in a  low-stress  environment such  as the
physician's  office  and  the  patient  will  typically  require  only  a  short
post-operative  recovery period, in some cases as little as 30 minutes. Patients
can usually resume normal activities by the following day.
 
    For the physician, the MicroSpan system reduces the amount of time  required
for  procedures  and provides  the flexibility  to  perform both  diagnostic and
operative  procedures  in  the  office.  The  MicroSpan  system  provides   high
resolution  and  light  efficiency  comparable  to  traditional,  large diameter
hysteroscopes. The design of the Company's proprietary micro-access device  will
enable  the physician to use  surgical instruments of the  same diameter used in
standard hysteroscopy procedures  for effective tissue  sampling and removal  of
many uterine lesions including adhesions, polyps and small fibroids. The ability
to   use   such  effective   surgical  instruments   in  conjunction   with  the
microhysteroscope will allow  physicians to  treat many  uterine disorders  with
accurate  micro-invasive procedures,  thus reducing  the need  for more invasive
surgical procedures.
 
    Industry sources estimate  that the cost  of a D&C  procedure under  general
anesthesia  is approximately  $2,400 to $3,000.  The Company  estimates that the
cost  of  a  standard  hysteroscopy   procedure  under  general  anesthesia   is
approximately  $2,600  to  $3,500  and  that  an  office-based microhysteroscopy
procedure will cost approximately $650 to $1,000.
 
Infertility
 
    Infertility  is  one  of  the  most  common  and  emotionally  traumatic  of
reproductive  disorders. Female infertility appears  to be increasing because of
both the  increase  in  diseases  which  damage  the  fallopian  tubes  and  the
increasing  tendency of  women to  defer childbearing  until later  in life when
fertility begins  to  decline  naturally.  In  general,  couples  who  have  not
conceived after one year of unprotected intercourse are considered infertile. In
the United States, recent government data estimates that approximately 5 million
women of child-bearing age suffer
 
                                       29
<PAGE>
from  an impaired ability to have  children. Despite the limited availability of
reimbursement for  infertility diagnosis  and assisted  reproductive  procedures
such  as intrauterine insemination and  in-vitro fertilization, approximately $2
billion is spent on the treatment of infertility annually in the United States.
 
    The causes  of  infertility  can  be complex  and  are  often  difficult  to
identify. A recent study indicates that abnormalities of the fallopian tubes are
responsible  for 30% to  50% of infertility  cases. The fallopian  tubes are the
sites where fertilization occurs and at least one fallopian tube must be open to
permit the passage of sperm to provide  fertilization of the egg and enable  the
fertilized  egg to pass to  the uterus. The fallopian  tubes are very narrow and
tortuous, delicate  and difficult  to access.  As  a result,  they do  not  lend
themselves  to  easy study  and treatment.  Current non-surgical  techniques for
diagnosing and  treating fallopian  tube disorders  often do  not adequately  or
accurately delineate the nature, extent and location of tubal pathology.
 
    CURRENT DIAGNOSIS AND TREATMENT
 
    Currently,  there are  two diagnostic  procedures utilized  by physicians to
determine whether the fallopian  tubes are patent (open)  or occluded. The  most
commonly  performed diagnostic procedure is hysterosalpingography ("HSG"), which
involves the  high-pressure  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 x-ray  fluoroscopy.  This
procedure  is  often  painful,  primarily  due  to  the  high-pressure injection
process, and is also highly inaccurate, with  as many as 25% of HSG cases  being
inaccurately  classified as blocked (false  positive). Nevertheless, due in part
to the  absence  of  more accurate,  non-invasive  diagnostic  techniques,  over
200,000 HSGs are performed annually in the United States.
 
    Due  to the frequent inaccuracy of HSG, in the event that an HSG indicates a
blockage of the fallopian tube, the physician will likely perform an  additional
procedure, known as laparoscopic chromopertubation. This procedure is similar to
HSG,  but involves the use of a laparoscope surgically positioned in the abdomen
to observe the flow of transcervically-injected dye through the fallopian tubes.
This procedure  has a  lower rate  (12%) of  false positive  diagnoses of  tubal
blockage,  but  involves the  potential complications  associated with  the more
invasive laparoscopic surgical procedure. The  Company estimates that there  are
approximately  180,000  chromopertubations  performed  annually  in  the  United
States.
 
    Although HSG and laparoscopic chromopertubation can provide some  diagnostic
information  regarding the patency  of fallopian tubes,  these procedures do not
provide any information regarding  the health of the  interior of the  fallopian
tubes,  which can be a significant factor contributing to infertility. Recently,
a procedure known as falloposcopy has been developed, in which a catheter device
containing a  visualization  scope  is  inserted through  the  cervix  into  the
fallopian  tubes  to  enable the  physician  to  visualize the  interior  of the
fallopian tube.  One  such system  uses  a guidewire-based  catheter  device  in
conjunction   with  other  procedures,  such  as  laparoscopy,  hysteroscopy  or
ultrasound, to assist  in guiding the  catheter into and  through the  fallopian
tubes.  Because falloposcopy enables the physician  to visualize the interior of
the fallopian  tube  and assess  its  health,  use of  falloposcopy  can  enable
physicians  to make more informed recommendations to patients regarding the next
course of action. Such courses of  action could include tubal surgery,  assisted
reproductive  techniques such as  in-vitro fertilization or  further attempts at
natural conception.
 
    Several surgical approaches are currently used to address infertility. These
procedures include  laparotomy,  or  open abdominal  surgery,  and  laparoscopic
surgery.  Both of these  procedures are performed in  the hospital under general
anesthesia and,  as a  result, involve  several risks,  including infection.  In
addition,  the recovery  period is  long, extending  to many  weeks for patients
undergoing laparotomy.  Furthermore, the  effectiveness of  these procedures  is
limited  as pregnancy is achieved  in only approximately 20%  to 25% of surgical
cases. As a result of the invasiveness and limited efficacy of these procedures,
few such  procedures  are  performed  in  the United  States  and  there  is  no
well-accepted method for opening blocked fallopian tubes.
 
    Consequently,  rather  than  undergo tubal  surgery,  many  patients attempt
in-vitro   fertilization.   In-vitro    fertilization   involves    drug-induced
superovulation,  harvesting  of  multiple  eggs  through  an  aspiration  needle
inserted into the ovary and fertilization of the harvested eggs with semen in  a
laboratory  test-tube fertilization procedure. Embryos are then transferred into
the uterus using a catheter placed through the cervix. In-vitro fertilization is
costly, with a single harvest and transfer, known as a cycle, costing an average
of $7,800, and is generally not
 
                                       30
<PAGE>
reimbursed by third-party  payors. Furthermore, many  patients undergo  multiple
cycles.  The drugs  administered to induce  superovulation are  powerful and can
have  significant  side  effects.  Finally,  the  success  rates  for   in-vitro
fertilization are low. However, notwithstanding the cost, lack of reimbursement,
need  to administer  powerful drugs  and limited  efficacy, approximately 38,000
in-vitro fertilization procedures are performed annually in the United States.
 
    THE IMAGYN OVATION SYSTEMS
 
    Imagyn's Ovation falloposcopy system and Ovation tubal recanalization system
are designed to  enable the physician  to access, navigate  and view the  entire
length  of the fallopian tube using a  flexible catheter and small scope. Unlike
HSG and chromopertubation, the Ovation falloposcopy system enables the physician
to view and accurately evaluate the  patency and overall health of the  interior
of  the fallopian tube.  Due to the unique  self-steering characteristics of the
Ovation falloposcopy  and tubal  recanalization  systems, visual  guidance  with
hysteroscopy  or ultrasound, which is  required with other falloposcopy systems,
is not required nor is there  the need for concurrent laparoscopic  manipulation
of  the fallopian  tube. The Ovation  falloposcopy system  has been specifically
designed to facilitate fallopian tube diagnosis in the physician's office.  Over
8,000 Ovation catheters have been shipped by the Company.
 
    The  Ovation tubal  recanalization system  has been  shown in  a controlled,
multi-center clinical trial in  Japan to unblock  occluded fallopian tubes.  The
Company  has received approval from the  Japanese Ministry of Health and Welfare
to  market  the   Ovation  tubal  recanalization   system  for  fallopian   tube
recanalization.
 
    The  Company has developed a modified version  of the Ovation system for use
in intrauterine insemination ("IUI"), a procedure in which sperm are  introduced
into  the uterine cavity.  The Ovation IUI  system permits the  traversal of the
cervix for  the purpose  of delivering  sperm into  the uterine  cavity  without
trauma  to the delicate lining of the uterus  in those cases in which the cervix
is very narrow and difficult to access.
 
Tubal Sterilization
 
    Tubal ligation,  a  procedure  for fallopian  tube  sterilization,  involves
surgically cutting and cauterizing the fallopian tubes. Tubal ligation is chosen
as  a permanent contraceptive method by  approximately 800,000 women annually in
the United States.
 
    CURRENT TUBAL LIGATION PROCEDURE
 
    Tubal ligation is  most commonly  performed in the  hospital, under  general
anesthesia,  by  means of  traditional  laparoscopic surgery  in  which surgical
devices are used to isolate and close the fallopian tube. Current tubal ligation
procedures require multiple large trocar punctures which must be sutured  closed
at  the  conclusion of  the procedure,  gas insufflation  to inflate  the pelvic
cavity and general anesthesia.  Patients are subjected  to pain associated  with
the  trocar punctures  and gas  insufflation as well  as the  risks and possible
complications associated with general anesthesia.
 
    THE IMAGYN MICROLAP SYSTEM FOR TUBAL STERILIZATION
 
    The MicroLap system enables physicians to visualize the performance of tubal
sterilization outside the hospital under conscious sedation, reducing  procedure
time  and cost,  as well  as recovery  time and  patient discomfort.  A recently
published study has indicated  that office-based tubal  ligation can reduce  the
cost  of the procedure to approximately $1,000, as compared to the approximately
$6,000 to $8,000 cost of a hospital-based tubal ligation procedure.

Advantages of Imagyn's Product Systems
 
    Imagyn's product systems enable  the micro-invasive diagnosis and  treatment
of  a broad  continuum of gynecological  and reproductive  disorders outside the
hospital, thereby reducing  the cost, trauma  and complications associated  with
operating  room procedures. Imagyn's product systems  have been designed to meet
the needs of physicians, patients and payors.
 
    ADDRESSING THE NEEDS OF PHYSICIANS
 
    - Improved diagnosis. Imagyn's product  systems provide physicians with  the
      necessary  visualization and access to  facilitate more accurate diagnosis
      of gynecological  and reproductive  disorders.  For example,  the  Ovation
      falloposcopy system is designed to allow physicians to view and accurately
      evaluate  the patency and overall health  of the interior of the fallopian
      tubes.
 
    - Minimal  training  threshold.  Imagyn's  MicroLap  and  MicroSpan  product
      systems  require  only  minimal  training  for  physicians.  For  example,
      physicians using the MicroLap will  employ the same procedural  techniques
      as  are  used  in  traditional  laparoscopy.  Because  falloposcopy  is  a
      relatively new procedure, more  training will be required  for use of  the
      Ovation falloposcopy system.
 
    - Enhanced  practice management. Imagyn's product systems are designed to be
      used in the office and with reduced procedure time, resulting in increased
      physicians' practice productivity. For example, the Company believes  that
      the  procedure  using  the  MicroLap  system  outside  the  hospital takes
      one-half  to  one-third  the  time  required  for  traditional  diagnostic
      laparoscopy in an operating room.
 
    ADDRESSING THE NEEDS OF PATIENTS
 
    - Reduced  trauma.  Imagyn's  small profile  product  systems  reduce access
      trauma, thereby reducing pain and the number and size of puncture  wounds.
      For  example,  due to  the small  size  of the  MicroLap, only  very small
      punctures are required to insert it  into the abdomen and sutures are  not
      required to close the puncture sites.
 
    - Fewer  complications.  Imagyn's product  systems are  designed to  be used
      without general anesthesia, enabling patients  to avoid many of the  risks
      and   complications  associated  with  current  invasive  procedures.  For
      example, the small diameter  of the MicroSpan  system eliminates the  need
      for  dilation of  the cervix so  the patient will  remain comfortable with
      only  local  anesthesia,   thereby  avoiding   complications  of   general
      anesthesia  such as allergic reaction,  pneumonia, nausea, and respiratory
      depression.
 
    - Faster recovery.  Imagyn's product  systems generally  enable patients  to
      return to normal activities within a 24-hour period following a procedure.
      For  example,  a patient  undergoing  a MicroLap  procedure  can generally
      resume normal activities the next day, while several days of  recuperation
      are often necessary for women undergoing traditional laparoscopy.
 
    ADDRESSING THE NEEDS OF PAYORS
 
    - Lower  cost. Imagyn's product systems can deliver significant cost savings
      to all payors by moving procedures  from the hospital to offices,  clinics
      and  outpatient settings, eliminating the need for general anesthesia, and
      reducing the potential for costly complications. For example, the MicroLap
      system has been  shown to reduce  costs for diagnostic  laparoscopy by  as
      much as 80% when performed in a physician's office rather than a hospital.
 
    - Earlier,   definitive  diagnosis.  Imagyn's   product  systems  facilitate
      earlier,  definitive  diagnosis,  reducing  the  likelihood  that   costly
      diagnostic  procedures  will  need  to be  repeated  and  that unnecessary
      operative procedures will be performed.  For example, the MicroLap  system
      can be used to perform "conscious pain mapping" to accurately identify the
      sources of pelvic pain thereby eliminating the need for further diagnostic
      or unnecessary operative procedures or expensive drug therapies.
 
    - Higher    patient   satisfaction.   Imagyn's   product   systems   provide
      time-efficient and micro-invasive care. The Company believes that patients
      will be drawn  to those providers  who can reduce  recovery time and  risk
      through the adoption of micro-invasive procedures.
 
                                       32
<PAGE>
    The  MicroLap system, the MicroSpan system and the Ovation systems represent
new approaches for the diagnosis and treatment of gynecological and reproductive
disorders and for tubal sterilization. Market acceptance of the MicroLap system,
the MicroSpan system and the Ovation systems will be dependent upon, among other
things, physicians' determinations  that the Company's  product systems and  the
procedures  in  which  they are  intended  to  be used  are  safe  and effective
alternatives to  current  hospital-based  procedures  and  demonstrate  clinical
utility,  and can be  used in a  cost-effective manner. In  addition, due to the
small size of the Company's micro-access devices, the Company's product  systems
are generally not appropriate for use in procedures which involve the removal of
substantial amounts of tissue or organs, such as the laparoscopic removal of the
gall bladder. In addition, procedures using the Company's product systems should
be  avoided with patients who have a heightened risk of uncontrollable bleeding,
are pregnant or have advanced cardiovascular disease.

    MICROLAP SYSTEM
 
    The  MicroLap system includes a  proprietary microlaparoscope, the MicroLap,
disposable  introducers  (for  placement  of  the  MicroLap  and   microsurgical
instruments  into the abdomen) and a broad line of microsurgical instruments for
use with the system. The MicroLap  is a reusable laparoscope which, at  slightly
less  than  2  millimeters in  diameter,  is  80% smaller  than  conventional 10
millimeter-diameter laparoscopes. The Company's
 
                                       33
<PAGE>
proprietary   micro-optics   technology   has   enabled   the   development   of
small-diameter    laparoscopes   having   resolution    and   light   efficiency
characteristics  which  the  Company  believes   are  comparable  to  those   of
conventional   laparoscopes  of  much  larger   diameter.  By  combining  unique
micro-lens design  with fused  image fiber  bundle technology,  the Company  has
achieved  up to five times the illumination and up to three times the resolution
of similar sized  microlaparoscopes. Additionally, the  Company's optics  design
provides  consistent and uniform edge-to-edge focus. Despite its small size, the
MicroLap is as durable as traditional rod or fixed lens laparoscopes due to  its
fiber  optic construction. The MicroLap is designed to be utilized by physicians
in a manner similar to larger laparoscopes. The MicroLap is compatible with  all
existing  medical  video cameras  and  light sources  and  does not  require any
additional specialized or ancillary equipment for its use.
 
    Imagyn's disposable introducers facilitate  atraumatic insertion and  secure
placement  of the MicroLap  and microsurgical instruments  through the abdominal
wall. The introducer is designed  to be placed through  the abdominal wall in  a
single step with a standard Veress needle and without the need for a trocar or a
separate  puncture  site  for insufflation.  The  introducer's  anchoring system
prevents inadvertent withdrawal during the  procedure and allows the  introducer
to  be  pulled up  tightly against  the  interior wall  of the  abdomen, thereby
providing maximum working  area in  the abdomen. The  introducer incorporates  a
side port for gas insufflation and a one-way check valve to prevent gas leakage.
Typically, several introducers are used during a microlaparoscopy procedure, one
for   the  MicroLap  and  others  to   permit  the  insertion  of  microsurgical
instruments.
 
    The Company has  also designed  a broad  line of  stainless steel,  reusable
microsurgical  instruments,  all  of which  are  2 millimeters  in  diameter and
compatible  with  the  MicroLap  introducer.  The  Company's  current  line   of
microsurgical instruments includes several graspers and scissors, a biopsy punch
for  tissue sampling, irrigation  and aspiration cannulae,  palpation probes and
monopolar electrocautery  probes  for the  cauterization  and removal  of  small
endometrial lesions and adhesions.
 
    CLINICAL  AND REGULATORY STATUS.  The  Company has received 510(k) marketing
clearances for the MicroLap, MicroLap introducer and a variety of  microsurgical
instruments  for  general  laparoscopic procedures.  USSC,  which  has exclusive
distribution rights in  international markets (excluding  China and India),  has
responsibility  for  individual  regulatory  approvals  in  those  markets.  See
"--Strategic Marketing Alliances" and "--Government Regulation."
 
    MICROSPAN SYSTEM
 
    The MicroSpan  system is  comprised of  a microhysteroscope,  a  proprietary
disposable  micro-access device and a line of microsurgical instruments. Because
the microhysteroscope utilizes  the proprietary micro-optic  technology used  in
the  MicroLap,  it is  significantly smaller  than current  rod, or  fixed, lens
hysteroscopes.  The   disposable  micro-access   device  provides   simultaneous
transcervical   access  to  the  uterus   for  both  the  microhysteroscope  and
microsurgical instruments without the need for the cervical dilation required by
currently available hysteroscopy  systems. Imagyn  has also designed  a line  of
reusable  hysteroscopic microsurgical instruments to  be used with the MicroSpan
system. These instruments include several graspers and scissors, a biopsy  punch
for  tissue sampling, palpation  probes and monopolar  electrocautery probes for
the cauterization  and removal  of  small fibroids,  polyps and  adhesions.  The
MicroSpan system is compatible with all existing medical video cameras and light
sources  and does not require any  additional specialized or ancillary equipment
for its use.
 
    CLINICAL AND REGULATORY STATUS.  The Company has submitted 510(k)  clearance
applications  for  the  microhysteroscope  and  microhysteroscopic  micro-access
devices. The  Company  plans to  seek  regulatory approval  in  those  countries
outside  the United States in which it intends to sell these products. There can
be no assurance  as to  when or  whether such  approvals will  be received.  See
"--Government Regulation."
 
    OVATION SYSTEMS
 
    Imagyn  has developed the Ovation  falloposcopy system for falloposcopy, the
Ovation tubal recanalization system for tubal recanalization and the Ovation IUI
system  for  intrauterine  insemination.  The  Ovation  falloposcopy  and  tubal
recanalization  systems  consist  of  a  proprietary  0.5  millimeter  diameter,
flexible  falloposcope,  a  proprietary  catheter,  and  a  specially   designed
irrigation  pump.  The  linear  everting  catheter  is  designed  to  enable the
physician to access, navigate and view  the entire length of the fallopian  tube
and  incorporates three elements: an inner  delivery catheter, an outer catheter
and an everting  balloon membrane.  A sliding mandrel  straightens and  stiffens
 
                                       34
<PAGE>
the  catheter tip  for placement  through a  non-dilated cervix  and an integral
falloposcope controller  provides  one-finger  control of  the  advancement  and
withdrawal  of the falloposcope. The linear  everting catheter's curved ball tip
is designed to enable  the catheter to atraumatically  engage the tubal  ostium,
facilitating  unguided access to the fallopian tubes from within the uterus. The
combination of  these elements  in a  single device,  together with  the  linear
everting  catheter's unique  "unrolling" design,  allows for  complete fallopian
tube access  and  visualization without  the  need for  concurrent  laparoscopic
guidance or hysteroscopic placement through the cervix, and without the need for
ancillary  devices, such  as guidewires for  accessing the  fallopian tubes. The
Ovation falloposcopy and  tubal recanalization systems  are compatible with  all
existing  medical  video cameras  and  light sources  and  does not  require any
additional specialized or ancillary equipment for its use.
 
                                       35
<PAGE>
    The diagram  below depicts  the  principal elements  of the  Ovation  linear
everting catheter.
 
                 [Diagram of Ovation Linear Everting Catheter]
 
    After  the catheter  tip is  placed through the  cervix, the  tip is rotated
toward either the right or left fallopian tube to engage the tubal ostium. Fluid
pressure is applied to  the everting balloon membrane  by means of an  inflation
device  and, in  combination with the  manual advancement of  the inner delivery
catheter, propels the everting balloon membrane forward into the fallopian tube.
As the  balloon membrane  gently unrolls  from the  inside out,  it carries  the
falloposcope  forward  without exerting  any  shear force  against  the delicate
lining of the  fallopian tube.  In contrast to  guidewire-based catheter  access
systems, the linear everting catheter's unique unrolling mechanism enables it to
traverse  the tortuous tubal anatomy without the need to push guidewires through
the  fallopian  tube  or  independently  manipulate  the  fallopian  tube   with
laparoscopic   or  other  ancillary  assistance.  Once  the  Ovation  system  is
positioned, it is designed to enable the physician is to view the entire  length
of  the  fallopian  tube  as  the catheter  and  falloposcope  are  withdrawn by
rerolling the catheter's everting balloon membrane.
 
    The Ovation  IUI  system  is  a  modified  catheter  that  incorporates  the
Company's  linear everting  catheter technology  for IUI,  a procedure  in which
sperm are introduced  into the uterine  cavity. The Ovation  IUI system  permits
traversal  of the cervix in  those cases in which the  cervix is very narrow and
difficult to  access  without trauma  to  the  delicate lining  of  the  uterus.
Following  placement of the Ovation IUI  system through the cervix, the everting
balloon membrane is unrolled a pre-set  distance into the uterus. A transfer  or
delivery  catheter containing sperm is placed through the central channel of the
catheter and the balloon membrane is slowly peeled back, exposing the tip of the
transfer catheter. The sperm are then expelled into the uterine cavity.
 
    CLINICAL  AND  REGULATORY  STATUS.    In  August  1995,  the  Ovation  tubal
recanalization  system was  approved for  marketing for  tubal recanalization in
Japan by the  Japanese Ministry of  Health and Welfare,  and an application  for
reimbursement  approvals within the Japanese health  care system is pending. The
Company has also received regulatory clearances in Germany, the United  Kingdom,
Australia   and  several  additional  international   markets  for  the  Ovation
falloposcopy system. The Japanese approval was based on a multi-center  clinical
study involving women who had experienced over four years of infertility. Of the
60  patients in the study who had  been diagnosed with bilateral tubal blockages
by HSG and laparoscopic chromopertubation  or some other modality, 49  patients,
or 82%, had tubal patency demonstrated by falloposcopy and confirmed with an HSG
procedure  two  months after  undergoing tubal  recanalization with  the Ovation
tubal recanalization system. Of the 55  patients in the Japanese clinical  study
who  were followed after tubal  recanalization to determine pregnancy prognosis,
17 patients,  or  31%, became  pregnant  during a  period  of up  to  two  years
following  the  tubal recanalization  procedure. This  post-tubal recanalization
pregnancy rate compares with  an approximately 20%  pregnancy rate for  in-vitro
fertilization in Japan.
 
                                       36
<PAGE>
    The   Ovation  falloposcopy  and  tubal  recanalization  systems  have  also
undergone clinical evaluation in Australia. The diagnostic information  obtained
through falloposcopy of 200 infertility patients enabled physicians to make more
informed  recommendations regarding subsequent courses  of action. This resulted
in a change  in clinical  management in approximately  70% of  cases, with  many
patients  being advised to again attempt natural conception. Of the 192 patients
followed after falloposcopy, 67 achieved pregnancy within two years, 42 of  whom
achieved  pregnancy  naturally. As  a  result, unnecessary  and  costly assisted
reproductive procedures were avoided.
 
    In the United States, the Ovation falloposcopy system has not been  approved
by  the FDA.  The system is  currently in a  controlled, randomized multi-center
clinical trial under an IDE approved by  the FDA in September 1995. The  purpose
of  the study is  to assess the  accuracy of the  Ovation falloposcopy system in
diagnosing the presence of blocked fallopian tubes in infertile women. To  date,
five  participating centers have received institutional review board approval to
commence the study,  and the first  patient was enrolled  in February 1996.  The
Company anticipates completion of the clinical study, with a targeted enrollment
of 100 patients, during 1996, although there can be no assurance that enrollment
will be completed within this time frame. Further, during the IDE study, the FDA
has  the authority  to review,  limit and/or  terminate the  study at  any time.
Following completion of the study, the Company will submit a PMA application  to
the  FDA for  approval to market  the Ovation falloposcopy  system for fallopian
tube diagnosis in the United States. Previously, under an FDA approved IDE,  the
Company  conducted a  multicenter clinical  trial during  1991 and  1992 for the
purpose of establishing the safety and efficacy of the linear everting  catheter
system  for falloposcopy  to access  and visualize  the fallopian  tubes. In May
1992, a PMA application  was submitted to  the FDA based on  the data from  this
clinical study. In January 1994, the FDA notified the Company of deficiencies in
its  PMA application,  particularly with respect  to the design  of the clinical
study, which  was not  structured as  a controlled,  randomized study,  and  the
breadth   of  the  Company's  visualization   claims.  Thereafter,  the  Company
unsuccessfully  attempted  to  address  the   FDA's  concerns  by  providing   a
reevaluation  of its clinical data and,  in September 1995, the Company withdrew
this PMA  application. Although  the Company  believes that  it has  reached  an
understanding  with the FDA  regarding the design and  clinical endpoints of the
current Ovation falloposcopy system  clinical study, there  can be no  assurance
that  the clinical study will be successful in demonstrating the efficacy of the
Ovation falloposcopy system in diagnosing  fallopian tube blockages or that  the
Company will receive FDA approval of a PMA for the system.
 
    The Company received 510(k) clearance for the Ovation IUI system in May 1995
and   is  currently  conducting  market  evaluation  prior  to  commencement  of
commercial  sales  and  distribution  of   the  Ovation  IUI  system  for   this
application.
 
Marketing, Sales and Distribution
 
    The  Company's  marketing  and  distribution strategy  consists  of  two key
elements: (i) focusing its  direct sales and  marketing resources on  gynecology
group   practices,  surgery   centers  and  infertility   specialists  and  (ii)
establishing strategic marketing alliances with major medical products companies
to accelerate  sales  growth, increase  geographic  market coverage  and  access
particular  markets and customers that can  be more effectively addressed by the
sales organizations of these companies.
 
                                       37
<PAGE>
    There  are  approximately  33,000  practicing  gynecologists  in  the United
States, approximately 33%  of whom perform  laparoscopic surgery,  approximately
15%  of whom are skilled  in hysteroscopy and approximately  80% of whom provide
some type of infertility services to their patients. Imagyn intends to focus its
direct sales  activities  on the  approximately  1,400 larger  gynecology  group
practices,   the  approximately   1,700  outpatient  surgery   centers  and  the
approximately 1,000  infertility  specialists in  the  United States  which  the
Company believes represent the highest concentration of demand for the Company's
products.  Gynecology practices consisting of  five or more physicians typically
have a sufficient number  of patients to  support an office-based  micro-surgery
practice.  The  Company  believes  outpatient surgery  centers  are  seeking new
procedures that  can be  performed  in their  facilities. The  Company  believes
infertility  specialists, most of whom are associated with the approximately 300
infertility centers in the United States, are seeking new approaches to diagnose
and address infertility problems.
 
    Imagyn plans  to build  a specialized  regional sales  force in  the  United
States  to market its  products directly to  gynecology group practices, surgery
centers and  infertility specialists.  The  Company has  recently hired  a  Vice
President  of  Sales  and  intends to  hire  approximately  25  sales personnel,
consisting of both field  sales personnel and regional  managers, in the  United
States  during the next  12 months. The  Company's direct sales  force will also
provide training in the applications for and the use of its products, as well as
financial models  of clinical  practice designed  to demonstrate  to payors  and
physicians the cost advantages of using the Company's products.
 
    In  addition to selling  directly to physicians  and administrators in these
target markets, Imagyn plans  to develop relationships  with opinion leaders  in
these  markets by sponsoring workshops and conferences to promote the discussion
of clinical issues and treatments. The Company also plans to generate acceptance
of  its  products   by  establishing  training   programs  at  leading   medical
institutions, such as its training centers for the use of its MicroLap system at
Yale University Medical School and Baylor College of Medicine.
 
    The  Company  intends  to  focus  a substantial  portion  of  its  sales and
marketing  efforts  on   facilitating  the  acceptance   and  adoption  of   its
procedure-specific  systems by third-party payor  organizations. Imagyn plans to
take advantage  of  current trends  in  managed  health care,  under  which  the
traditional  fee-for-service system is being  replaced by integrated health care
delivery  systems,  preferred   provider  organizations   ("PPOs")  and   health
maintenance  organizations ("HMOs"), by improving  patient care, reducing trauma
and  facilitating  the  movement  of  procedures  that  have  historically  been
performed in the hospital to physicians' offices, clinics and outpatient surgery
centers.
 
    The  Company also intends to sponsor patient education programs and increase
women's awareness  of  the  benefits of  the  Company's  micro-invasive  product
systems.
 
    Internationally,  the Company currently  markets the Ovation  systems in the
United Kingdom, Germany and Australia through  a limited number of direct  sales
personnel  who  are assisted  by  agents. The  Ovation  systems are  marketed by
distributors in Italy,  Austria and Spain.  Imagyn also intends  to establish  a
network  of  distributors  for  its MicroSpan  system  in  certain international
markets. The distribution  agreements with distributors  of the Ovation  systems
grant  the distributors the  exclusive right to sell  the Ovation systems within
defined territories in  exchange for covenants  prohibiting them from  marketing
medical  devices  that compete  directly with  these products.  The distributors
purchase the  products  from  the Company  at  a  discount from  list  price  in
transactions  denominated  in United  States  dollars. The  end-user  prices are
determined by the distributors and vary from country to country.
 
    The Company has only limited experience marketing and selling its  products,
and  does not have  experience marketing and selling  its products in commercial
quantities. Establishing marketing  and sales capability  sufficient to  support
sales  in commercial quantities  will require significant  resources and will be
time-consuming, and there can be no assurance  that the Company will be able  to
recruit  and  retain qualified  marketing personnel,  direct sales  personnel or
contract sales  representatives in  a timely  manner or  that future  sales  and
marketing  efforts of the Company will be  successful. There can be no assurance
that the  Company  will  be  successful in  establishing  marketing,  sales  and
distribution  channels in the  United States or  internationally. The failure to
establish  and  maintain  effective  distribution  channels  for  the  Company's
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.

Strategic Marketing Alliances
 
    UNITED STATES SURGICAL CORPORATION
 
    In  October 1995, the  Company entered into an  agreement with United States
Surgical Corporation  ("USSC")  pursuant to  which  USSC was  granted  exclusive
international  marketing  rights  for  the  Company's  MicroLap  system  in  all
international markets (excluding China and India).  USSC was also granted, on  a
co-exclusive  basis with the Company, marketing rights to the MicroLap system in
the United States.  Under the terms  of the agreement,  Imagyn will  manufacture
private  label products for USSC for sale  and distribution in the United States
and international markets. USSC is required to obtain appropriate  international
product  registrations and regulatory  approvals in those  markets in which USSC
plans to distribute the MicroLap system, except that the Company is required, at
its expense, to obtain a  CE mark for the system.  USSC is also responsible  for
all  sales  and  marketing expenses  in  connection  with the  sale  of MicroLap
systems. Furthermore, USSC is subject  to minimum annual purchase  requirements.
The  Company's agreement  with USSC  may be terminated  by USSC  upon six months
notice at any time after October 23, 1997. Imagyn may terminate the agreement at
any  time  if  USSC  introduces   products  which  compete  with  the   MicroLap
microlaparoscope.
 
    USSC  has a substantial sales force  that markets products primarily for use
in hospital-based surgical procedures.  Because most laparoscopy procedures  are
currently  performed in  a hospital,  the Company  believes that  the ability to
expose physicians to the MicroLap system  in a hospital setting will  accelerate
the  adoption  of the  MicroLap  system by  physicians  and will  facilitate the
movement of  microlaparoscopy procedures  out of  the hospital.  Therefore,  the
Company  believes that the efforts of  its direct sales organization, which will
be focused  on  gynecology  group practices,  surgery  centers  and  infertility
specialists, will be complementary to the sales and marketing efforts of USSC.
 
    TERUMO CORPORATION
 
    In  August 1995, Terumo Corporation  ("Terumo") obtained Japanese regulatory
approval for  use of  the Ovation  tubal recanalization  system pursuant  to  an
agreement  between  the Company  and Terumo  for  the distribution  and licensed
manufacture of the  Ovation systems  in Japan.  Under the  agreement, Terumo,  a
Japan-based multinational hospital products supplier, has been granted sales and
distribution  rights  for the  Ovation systems  in  Japan. Under  the agreement,
Terumo is  responsible  for  obtaining  Japanese  regulatory  and  reimbursement
approvals  as well  as for the  cost of  all sales and  marketing activities for
these products in  Japan. Terumo recently  applied to the  Japanese Ministry  of
Health   and   Welfare  for   reimbursement  approval   of  the   Ovation  tubal
recanalization system  in  Japan.  Through  August  1997,  Terumo  may  purchase
products,  denominated in United States dollars,  from Imagyn at a discount from
United States  list price  and resell  the products  to hospitals,  clinics  and
physicians. The end-user price is determined solely at the discretion of Terumo.
At  the  end  of this  two  year period,  Imagyn  is obligated  to  transfer the
manufacturing know-how necessary  to permit  Terumo to  manufacture the  Ovation
catheters  and falloposcopes for sale in Japan. Terumo is required to pay Imagyn
royalties on the sales of these products until such time as the Japanese patents
covering these products expire. Terumo may, at its option, continue to  purchase
other  ancillary  products from  Imagyn  that are  used  in connection  with the
Ovation systems.
 
    The Company  is dependent  upon USSC  and Terumo  for marketing,  sales  and
distribution  of the  products covered by  their respective  agreements in their
respective territories. The Company is dependent upon Terumo for regulatory  and
reimbursement  approvals in Japan, and, although Terumo has obtained approval of
the linear everting system for tubal  recanalization, there can be no  assurance
that Terumo will comply with the conditions of such approval or that Terumo will
be  able to  obtain reimbursement approvals  in Japan. The  Company is dependent
upon  USSC  to  obtain  appropriate  international  product  registrations   and
regulatory  approvals in  those markets  in which  USSC plans  to distribute the
MicroLap system, except that Imagyn is obligated, at its expense, to obtain a CE
mark, an international symbol  of adherence to  quality assurance standards  and
compliance  with applicable  European Union  Medical Device  Directives, for the
MicroLap system.  The Company  is  dependent upon  Terumo  and USSC  to  support
reimbursement  approval  for  their  respective  products  in  their  respective
territories. In the event  that USSC and Terumo  are unable to obtain  necessary
regulatory   approvals  for  their  respective   products  in  their  respective
territories, fail  to  devote  sufficient resources  to  promote  the  Company's
products,  or fail  to support  reimbursement approvals,  sales of  the products
covered by the agreements with USSC and Terumo could be materially and adversely
affected, which in turn  would have a material  adverse effect on the  Company's
business,
 
                                       38
<PAGE>
financial  condition and results  of operations. The Company  has also agreed to
indemnify USSC  and  Terumo  against  claims  of  infringement  of  intellectual
property  rights. Furthermore, the Company's  rights to terminate the agreements
with USSC and Terumo are limited, and, accordingly, the Company may be unable to
establish alternative marketing or  distribution arrangements if the  agreements
with  USSC  and Terumo  are not  successful.  The failure  or loss  of strategic
alliances with USSC and Terumo, or the Company's inability to enter into  future
necessary  strategic  alliances, would  have a  material  adverse effect  on the
Company's business, financial condition and results of operations.
 
Research and Development
 
    Imagyn's research and  development activities  are performed  in-house by  a
group consisting of 11 engineers and technicans. The efforts of the research and
development group are supplemented by outside physician experts and consultants.
The Company also makes use of technical and engineering consultants as required.
 
    In  microlaparoscopy, the Company is developing new electrocautery and other
microsurgical  instruments  to  broaden  its  MicroLap  product  line  and   the
applications  for the  MicroLap system.  Enhancements under  development for the
Company's microhysteroscopy  technology  include microhysteroscopic  biopsy  and
electrocautery   devices.  In   addition,  Imagyn  is   directing  research  and
development efforts toward enhancing its proprietary micro-access technology for
both microhysteroscopy and microlaparoscopy. The Company is also developing  new
applications  for its proprietary linear everting catheter technology as well as
a curved proboscis tip for the  Ovation falloposcopy system that is designed  to
improve visualization during falloposcopy.
 
    The  product development process is time-consuming and costly, and there can
be no assurance that any new product development will be successfully completed,
that necessary regulatory clearances or approvals will be granted by the FDA  or
international  regulatory authorities on a timely basis,  or at all, or that any
new products  developed  and  introduced  by the  Company  will  receive  market
acceptance.  Failure  by the  Company  to develop,  obtain  necessary regulatory
clearances or approvals for, or successfully  market new products, could have  a
material  adverse  effect on  the  Company's business,  financial  condition and
results of operations.
 
    The Company's research  and development  expenditures totaled  approximately
$1.8, $1.8 and $1.9 million in the years ended December 31, 1995, 1994 and 1993,
respectively.
 
Manufacturing
 
    The  Company manufactures its  proprietary microlaparoscopes, falloposcopes,
linear everting  catheters and  micro-access  devices in  a  clean room  at  its
facility  in  Laguna  Niguel,  California.  The  Company  plans  to  expand  its
operations in 1996 to  increase manufacturing capacity  by adding an  additional
clean  room and  quality control  space, and  the Company  has leased  the space
necessary for this expansion.
 
    Components are purchased from a  variety of vendors, subjected to  stringent
quality  specifications and  assembled by Imagyn's  highly skilled manufacturing
technicians into finished  products. Final assembly  and packaging is  currently
performed  by the Company in-house and  sterilization is performed by an outside
vendor. The manufacturing  processes for microlaparoscopes  and linear  everting
catheters are complex and require precision in producing, assembling and testing
components  and finished  products. Many of  the steps in  the assembly process,
such as grinding and polishing lenses and optical fibers, are performed under  a
microscope, requiring up to 80x magnification.
 
    The  Company has  only limited experience  in manufacturing  its products in
commercial quantities  and has  not  manufactured any  of  its products  in  the
quantities  that  will be  necessary for  achievement of  significant commercial
sales or profitability. In  addition to manufacturing  certain of its  products,
Imagyn  purchases other components of its  product systems from outside vendors.
The Company has limited manufacturing capacity and will be required to  increase
both  its in-house  manufacturing capability and  the size  of its manufacturing
facilities. Although the Company has leased the space that it will use to expand
its manufacturing facilities, there can be no assurance that the Company will be
able to complete its facility expansion, attract, train and retain the  required
personnel,  including personnel  skilled in micro-optics  assembly processes, or
increase its manufacturing capability and capacity in a timely manner. There can
be no assurance that reliable,  high-volume manufacturing can be established  or
maintained  at  commercially reasonable  costs  on a  timely  basis, or  at all.
Manufacturers often encounter  difficulties in  scaling up  production of  their
products,  including problems  involving production yields,  quality control and
 
                                       39
<PAGE>
assurance, component supply and shortages of qualified personnel. If the Company
is unable  to increase  its in-house  manufacturing capability  or  successfully
complete  the expansion of its manufacturing  facilities in a timely manner, the
Company may need  to obtain  alternative manufacturing  facilities or  establish
contract  manufacturing  for  its  products,  and  delays  associated  with,  or
inability to establish, such additional  capacity could have a material  adverse
effect on the Company's business, financial condition and results of operations.
 
    Certain  of the components used in  the Company's product systems, including
the optic image fiber used in the MicroLap, a similar version of which will also
be used in the MicroSpan and the  medical video camera and light source used  in
connection with the Ovation tubal recanalization system, are currently purchased
from  single sources.  Currently, the  Company has  a supply  agreement with the
MicroLap image fiber  supplier; however,  there can  be no  assurance that  such
supplier  will be able to or will continue to supply image fibers to the Company
in the amounts and at the times needed by the Company or that other  disruptions
in  supply will not  occur. The number  of manufacturers capable  of making such
optical image fibers  is limited  and, to date,  the Company  has not  qualified
additional  suppliers for such optical image fibers. The Company believes it can
qualify an additional source for such optical image fiber; however, there can be
no assurance as  to when or  whether the Company  will be able  to qualify  such
supplier.  The Company's  prior supplier  of Ovation  medical video  cameras and
light sources ceased  manufacturing such products  in late 1995  as a result  of
financial  difficulties, which resulted in an temporary inability of the Company
to supply such components to Terumo. As a result, the Company was unable to ship
Ovation medical  video cameras  and light  sources  to Terumo  for a  period  of
approximately  six  months. Although  the  Company has  qualified  a replacement
supplier, there can  be no  assurance that  future supply  disruptions for  such
components   will  not  occur.  The  Company  also  uses  a  single  vendor  for
sterilization of  its products,  and disruptions  in sterilization  of  finished
products  could  adversely  affect the  Company.  Furthermore, there  can  be no
assurance that  the Company  will not  encounter future  component shortages  or
other disruptions in supply of materials or services. Delays associated with any
future raw materials or component 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.
 
    The Company's  products are  complex  devices designed  for use  inside  and
around  the organs of the  female reproductive system. To  date, the Company has
only limited experience regarding the reliability of its products in the  field.
Component  failures, manufacturing errors  or design defects  could result in an
unsafe condition or injury to the patient. If any such failures or defects  were
material,  the Company  could be  required to  undertake a  market withdrawal or
recall of products. Even if regulatory  approvals are obtained, there can be  no
assurance  that a market withdrawal or product recall will not occur. Costs of a
market withdrawal  or product  recall  could be  significant  and could  have  a
material  adverse  effect on  the  Company's business,  financial  condition and
results of operations.
 
Patents, Trade Secrets and Licenses
 
    Imagyn's ability to compete effectively will  depend in part on its  ability
to  develop and maintain proprietary aspects  of its technology. Imagyn seeks to
protect its proprietary  position aggressively  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.
 
    As of April 15, 1996, the Company held 13 issued United States patents and 3
issued  foreign  patents  and  had  11  United  States  and  10  foreign  patent
applications pending, covering various aspects of the Company's product systems.
The  Company's  issued United  States  patents cover  technology  underlying the
Ovation systems. The expiration dates of  these patents range from October  2011
to May 2014.
 
    In  addition to  its patents  and patent  applications, the  Company holds a
license from Baxter  Healthcare Corporation  ("Baxter") and  Thomas J.  Fogarty,
M.D.  ("Fogarty"), the  inventor of  the linear  everting catheter,  that grants
Imagyn the  exclusive,  perpetual,  worldwide use  of  patented  technology  and
know-how  related to  the linear everting  catheter technology in  the fields of
obstetrics, gynecology, and infertility, in exchange for royalty payments. As of
April 15,  1996,  Baxter and  Fogarty  held, and  Imagyn  has been  granted  the
exclusive  license  for, 11  issued United  States  patents and  numerous issued
foreign patents and  pending applications  covering aspects  of linear  everting
catheter  technology. The  license agreement  requires that  Baxter maintain and
prosecute all patents and  patent applications relating  to the linear  everting
catheter technology.
 
                                       40
<PAGE>
    No  assurance can be given that any patents from pending patent applications
or from any future  patent applications will  be issued, that  the scope of  any
patent  protection will exclude competitors or provide competitive advantages to
the  Company,  that  any  of  the  Company's  patents  will  be  held  valid  if
subsequently  challenged or that others will not claim rights in or ownership of
the patents and other proprietary rights held by the Company. Furthermore, there
can be no assurance that others have  not developed or will not develop  similar
products, duplicate any of the Company's products or design around the Company's
patents.  In  addition,  others  may  hold or  receive  patents  or  file patent
applications which contain claims having a scope that covers products  developed
by the Company.
 
    The  medical device industry has  been characterized by extensive litigation
regarding patents and other intellectual property rights, and many companies  in
the   industry  have  employed  intellectual   property  litigation  to  gain  a
competitive advantage.  There can  be no  assurance that  the Company  will  not
become  subject to patent infringement  litigation or an interference proceeding
declared by the United States Patent and Trademark Office ("USPTO") to determine
the priority of inventions. The defense  and prosecution of patent 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 would
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.
 
    In addition to patents, the Company relies on trade secrets and  proprietary
know-how  to compete,  which it seeks  to protect, in  part, through appropriate
confidentiality  and  proprietary   information  agreements.  These   agreements
generally  provide that all confidential information  developed or made known to
individuals by  the Company  during  the course  of  the 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 service to the
Company shall  be  the  exclusive property  of  the  Company. There  can  be  no
assurance  that  proprietary  information  or  confidentiality  agreements  with
employees, consultants and others  will not be breached,  that the Company  will
have  adequate remedies for any breach, or that the Company's trade secrets will
not otherwise become known to or independently developed by competitors.
 
Government Regulation
 
    UNITED STATES
 
    The  research,   development,  testing,   manufacture,  labeling,   storage,
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
("FDC Act")  and  most  require  clearance  or approval  by  the  FDA  prior  to
commercialization.  In addition,  certain 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, 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 expensive, lengthy and uncertain.  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, or withdrawal  of,
premarket clearance or premarket approval for devices, and criminal prosecution.
 
                                       41
<PAGE>
    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  Investigational  Device  Exemption ("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  specified  number  of  investigational sites
involving a specified maximum  number of patients, as  approved by the FDA.  The
clinical  trials  are  required  to  be  conducted  under  the  auspices  of  an
Institutional Review Board ("IRB"). During the IDE study, the FDA has  authority
to  review, limit,  or terminate  the study at  any time.  Discontinuance of the
study could have a material adverse effect on the Company's business,  financial
condition and results of operations.
 
    Before  a new medical device may be introduced into the market in the United
States,  the  manufacturer  or  distributor  generally  must  obtain   marketing
clearance  from  the FDA  through either  a 510(k)  premarket notification  or a
premarket approval ("PMA") application. If  the manufacturer or distributor  can
establish,  among other things,  that a device  is "substantially equivalent" in
that it has the same intended use and the same technological characteristics  as
the  predicate device or has different technological characteristics that do not
raise different questions of safety and efficacy than the predicate device,  the
manufacturer  or  distributor  may  seek  clearance  to  market  the  device  by
submitting a 510(k) premarket notification.  Following submission of the  510(k)
premarket notification, the manufacturer or distributor may not place the device
into   commercial  distribution  unless  and  until  a  finding  of  substantial
equivalence  is  issued  by  the  FDA.   In  response  to  a  510(k)   premarket
notification, the FDA may declare that the device is substantially equivalent to
a  predicate device and allow  the proposed device to  be marketed in the United
States. Alternatively,  the  FDA  may  require  further  information,  including
clinical  data, to make its  determination regarding substantial equivalence, or
the FDA may determine that the  proposed device is not substantially  equivalent
to the predicate device, and require the manufacturer or distributor to submit a
PMA.  An  FDA request  for additional  information or  a determination  that the
device is not substantially  equivalent would delay  market introduction of  the
products that are the subject of the 510(k) premarket notification.
 
    As  of April 15, 1996, the Company had received eleven 510(k) clearances for
certain diagnostic  and/or  therapeutic  indications  of  its  microlaparoscopy,
microhysteroscopy and linear everting catheter intrauterine insemination product
systems.
 
    If  the manufacturer or distributor cannot  establish that a proposed device
is  substantially  equivalent  to  a  legally  marketed  predicate  device,  the
manufacturer  or distributor must seek premarket approval of the proposed device
through submission of a PMA application. A PMA application must be supported  by
extensive  data, including  laboratory, preclinical  and clinical  trial data to
prove the safety and efficacy of the device, as well as extensive  manufacturing
information.  If the FDA  determines, upon initial review,  that a submitted PMA
application is sufficiently complete to permit substantive review, the FDA  will
accept the PMA application for filing. FDA review of a PMA application generally
takes  approximately two years or  more from the date  of acceptance for filing,
but review times vary depending upon FDA resources and workload demands and  the
complexity  of PMA  submissions. There  can be  no assurance  that the  FDA will
review and approve the PMA in a timely manner, if at all. Failure to obtain  PMA
approvals  could  have  a material  adverse  effect on  the  Company's business,
financial condition  and results  of  operations. Additionally,  as one  of  the
conditions for approval, the FDA will inspect the manufacturing establishment at
which  the subject device will be  manufactured to determine whether the quality
control and manufacturing procedures conform to GMP regulations. If granted, the
PMA approval may include significant limitations on the indicated uses for which
the device may be marketed.
 
    The Company does not have FDA  approval for its Ovation falloposcopy  system
or  tubal recanalization system, and  intends to file a  PMA application for the
Ovation falloposcopy system. Under an FDA approved IDE, the Company conducted  a
multi-center,  United States clinical trial for  the purpose of establishing the
safe and effective use of the  linear everting catheter system for  falloposcopy
to  access and visualize the fallopian tubes. In May 1992, the Company submitted
a PMA application to the  FDA, which included data  from the clinical trial.  In
January  1994,  the  FDA  notified  the  Company  of  deficiencies  in  its  PMA
application, particularly with respect  to the study design  and breadth of  the
visualization  claim. The  Company attempted  to address  the FDA's  concerns by
providing a reevaluation  of its clinical  data; however, the  FDA did not  find
this  analysis acceptable and, in September  1995, the Company withdrew this PMA
application. In July 1995, the FDA and the Company agreed on a new study design,
and an  IDE for  the  study was  approved  by the  FDA  in September  1995.  The
indication was narrowed from
 
                                       42
<PAGE>
that  in the  previous PMA  (i.e., from "to  access and  visualize the fallopian
tubes" to "diagnosis  of the presence  of occlusions in  the fallopian tubes  of
infertile  women").  Five  participating  United  States  centers  have received
necessary IRB approvals for the study, and the first patient was enrolled in the
study in February 1996.
 
    There can be no assurance that the Company will be able to obtain  necessary
510(k)  clearances or PMA approvals to market  its products in the United States
for their intended uses on a timely basis,  if at all, and delays in receipt  of
or failure to receive such approvals, the loss of previously received 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.
 
    The  Company  is also  required  to register  with  the FDA  and  with state
agencies such as  the California  Department of  Health Services  ("CDHS") as  a
medical   device  manufacturer,  and   to  list  its   products  with  the  FDA.
Consequently, the Company's  facilities will be  inspected periodically by  both
the  FDA and CDHS to determine whether  the Company manufactures its products in
compliance with FDA  Good Manufacturing Practices  ("GMP") and other  applicable
regulations.  In November 1995, the Company's  facility was inspected by the FDA
for a routine GMP inspection. The  FDA noted several observations, to which  the
Company  responded. The Company has received FDA confirmation of the adequacy of
its responses.
 
    The Company is also required, upon commercialization, to provide information
to the FDA concerning any death or  serious injury that its medical devices  may
have allegedly caused or contributed to, as well as any product malfunction that
would  likely cause or contribute to death  or serious injury if the malfunction
were to recur.  Also, if  safety or efficacy  problems occur  after the  product
reaches the market, the FDA may take steps to prevent or limit further marketing
of the product. In addition, the FDA prohibits the marketing of approved devices
for uses other than those specifically cleared for marketing by the FDA. Failure
to comply with applicable FDA regulations can result in FDA warning letters, FDA
refusal  to approve  or clear  products, revocation  or withdrawal  of approvals
previously granted,  civil penalties,  product seizures,  injunctions,  recalls,
operating  restrictions  and criminal  prosecution and  penalties. Consequently,
failure by  the Company  to comply  with 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  the
jurisdiction of the FDA, Federal Trade Commission and related state authorities.
The  Company  also is  subject  to various  federal,  state and  local  laws and
regulations  relating  to  occupational  safety,  laboratory  and  manufacturing
practices,  and  the  use, handling  and  disposal of  hazardous  or potentially
hazardous substances. There  can be no  assurance that the  Company will not  be
required  to incur significant costs  in the future to  comply with such laws or
will be able to  continue to comply  with such laws  and regulations, which  are
subject to change. FDA regulations regarding the research, development, testing,
manufacture,  labeling,  storage, distribution  and  marketing of  the Company's
products are subject to change. The Company cannot predict what effect, if  any,
such  changes  might have  on its  business, financial  condition or  results of
operations.
 
    INTERNATIONAL
 
    Sales of medical devices  outside the United States  are subject to  foreign
regulatory  requirements  that vary  widely from  country  to country.  The time
required to obtain registrations or approvals required by foreign countries  may
be  longer or  shorter than  that required  for FDA  clearance or  approval, and
requirements for licensing may differ significantly from FDA requirements.  Some
countries  have  historically permitted  human  studies earlier  in  the product
development cycle than regulations in the United States permit. Other countries,
such as Japan,  have requirements similar  to those of  the United States.  This
disparity  in the  regulation of  medical devices  may result  in slower product
clearance in  certain countries  than in  others. Many  countries in  which  the
Company  operates or intends to operate either do not currently regulate medical
devices  or  have  minimal  device  registration  requirements;  however,  these
countries  may  develop  more extensive  regulations  in the  future  that could
adversely affect the Company's ability to market its products.
 
    Pursuant to  the  Company's distributorship  agreement  with USSC,  USSC  is
required  to  obtain  appropriate  international  regulatory  registrations  and
approvals in  those markets  in which  USSC plans  to distribute  the  Company's
MicroLap system, except that the Company is required to obtain a CE mark for the
system.
 
                                       43
<PAGE>
    In  August 1995, following  completion of a  clinical trial, Terumo received
import  approval  from  the  Japanese  Ministry  of  Health  for  the  sale  and
distribution  of the Company's linear everting  catheter system in Japan for use
in fallopian tube recanalization.
 
    The Company has received registrations  and approvals to market its  Ovation
systems  in Australia, Austria, France,  Germany, Italy, Singapore, South Korea,
Taiwan, the United Kingdom, Switzerland, Denmark and The Netherlands.
 
    All of the medical devices currently  manufactured by the Company which  are
distributed  in the European Union ("EU") will be subject to the Medical Devices
Directive ("MDD") when  the transition period  for the MDD  expires on June  13,
1998. To comply with the MDD, the Company will need to obtain the right to affix
the  CE mark  on its medical  devices. The  right to affix  the CE  mark must be
obtained from one of  the organizations in the  EU, known as "Notified  Bodies,"
which  are  designated by  individual  member states  as  competent to  grant to
companies the right to affix the CE  mark on their medical devices. The CE  mark
will  show that the Company is entitled to  market its medical devices in the EU
because they meet all the  essential requirements of the  MDD. The CE mark  will
permit  the Company's  medical devices  to circulate  freely throughout  the EU.
Without receipt of the right  to affix the CE mark  on its medical devices,  the
Company's  medical devices will not  be able to be  marketed anywhere in the EU.
The Company  is currently  in  the process  of taking  the  steps that  will  be
necessary to comply with the essential requirements of the MDD, but there can be
no  assurance that by taking these steps,  the Company will be granted the right
to affix the CE mark on any of its medical devices by a Notified Body.
 
    In the EU,  some accessories  to the  Company's products,  such as  cameras,
pumps  and  light  sources,  are subject  to  the  Electromagnetic Compatibility
Directive ("EMC Directive") or similar laws of EU member states. The  transition
period  for the EMC Directive expired on December 31, 1995. Due to the volume of
electrical and electronic devices of all types, including medical devices, which
must be  tested  in  order  to  determine  whether  they  comply  with  the  EMC
Directive's  requirements, many companies  have not been  able to complete their
testing and review obligations through the Notified Bodies that must confirm EMC
Directive  compliance.  In  acknowledgment  of  industry  delays,  an   informal
understanding has been reached between member states of the EU and EU Commission
officials that enforcement/compliance actions relating to the EMC Directive will
similarly be delayed until January 1, 1997. The Company is currently undertaking
the  necessary steps to  be in compliance  with the EMC  Directive by January 1,
1997.
 
    Export sales  of investigational  PMA  devices or  devices not  cleared  for
commercial  sale  in  the  United  States  are  subject  to  FDA  export  permit
requirements. In order to obtain an export permit, the exporter 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. The  Company  has
received  certain export  approvals for the  Ovation systems  for Australia, The
Netherlands, Denmark,  France, Italy,  Norway, Sweden  and Switzerland,  and  is
seeking  export approvals for other countries. Recently proposed FDA regulations
would eliminate  export  approval  requirements for  export  of  investigational
devices  that are  the subjects of  FDA-approved IDEs to  certain countries that
have expressed approval  of the  importation of such  devices. There  can be  no
assurance, however, that the final regulations will contain the same language as
the  proposed regulations,  and the  final regulations  may revise  the proposed
regulations in such a way that could adversely affect the Company's existing  or
future export operations.
 
Third-Party Reimbursement
 
    In  the United States, hospitals, physicians and other health care providers
that purchase  medical devices,  such as  Imagyn's products,  generally rely  on
third-party  payors, principally private health insurance plans and, to a lesser
extent, federal Medicare  and state Medicaid,  to reimburse all  or part of  the
cost of the procedure in which the medical device is being used.
 
    Reimbursement  in the United  States for procedures  performed in hospitals,
ambulatory  care   centers   or   physicians'  offices   using   the   Company's
microlaparoscopy  products is currently available  from most third-party payors,
including most major  private health  care insurance plans  and Medicaid,  under
existing  procedure codes. However, there is currently no specific reimbursement
code for office-based microlaparoscopy procedures.  The Company does not  expect
that  third-party  reimbursement  in the  United  States will  be  available for
procedures
 
                                       44

performed using the Company's MicroSpan or Ovation systems unless and until  FDA
clearance  or  approval for  such  products is  received.  If FDA  clearances or
approvals are received,  third-party reimbursement  for these  products will  be
dependent upon decisions by individual health maintenance organizations, private
insurers  and other payors. The Company believes that procedures performed using
Imagyn's MicroSpan system could,  following receipt of  FDA clearances for  such
system,  be reimbursed in  the United States under  existing procedure codes for
diagnostic and therapeutic  hysteroscopy procedures.  However, there  can be  no
assurance  that  such procedure  codes  will be  available  with respect  to the
Company's products or that the reimbursement under these codes will be adequate.
To the extent cost containment measures imposed by third party payors  adversely
affect  the hospital and private practice markets, demand for and pricing of the
Company's products could be adversely affected as well.
 
    Certain health care  providers are moving  toward a managed  care system  in
which  such providers contract to provide  comprehensive health care for a fixed
cost per person. Imagyn is  unable to predict what changes  will be made in  the
reimbursement  methods  utilized  by  third-party  health  care  payors.  Imagyn
anticipates that hospital administrators and physicians would justify the use of
its products  by the  attendant  cost savings  and  clinical benefits  that  the
Company  believes would be derived from the  use of its products. However, there
can be no assurance that this will  be the case. Furthermore, the Company  could
be  adversely affected  by changes  in reimbursement  policies of  government or
private health care payors, particularly to  the extent any such changes  affect
reimbursement  for  the  procedure 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 health care  payors for  the procedure 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.
 
    Reimbursement systems in international markets vary significantly by country
and,  within some countries, by region. Reimbursement approvals must be obtained
on a country-by-country  basis. Many  countries have  government managed  health
care  systems  that  determine whether  reimbursement  will be  granted  for new
medical  devices  and  procedures,  as   well  as  private  insurance   systems.
Broad-based  foreign market acceptance of  the Company's MicroLap, MicroSpan and
Ovation  systems  will  depend  in  part  on  the  availability  and  level   of
reimbursement  in  the  international  markets  targeted  by  the  Company.  The
Company's Ovation falloposcopy  system has  been approved  for reimbursement  in
Australia  and  Germany. Terumo  recently applied  to  the Japanese  Ministry of
Health  and   Welfare  for   reimbursement  approval   of  the   Ovation   tubal
recanalization system in Japan. The process of obtaining reimbursement approvals
can be lengthy and unpredictable, and there can be no assurance that the Company
will  obtain reimbursement approvals in  Japan or in any  other country within a
particular time,  for a  particular amount,  or at  all. Even  if  reimbursement
approval  is obtained, due to  the pressure of rising  health care costs in many
countries, there can be no assurance that  such approval will not be limited  or
withdrawn  at any time. Failure to obtain or maintain such approvals for some or
all of  the Company's  products could  have  a material  adverse effect  on  the
Company's business, financial condition and results of operations.
 
    Physician  adoption  of the  Company's  products and  physician  advocacy of
reimbursement of procedures performed using them  will be necessary in order  to
obtain reimbursement from government and private payors for procedures performed
using  Imagyn's products. The  availability of reimbursement  will depend on the
clinical efficacy and cost of the  Company's products and 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 uses  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 performed using the Company's products would have a
material  adverse  effect on  the  Company's business,  financial  condition and
results of operations.
 
Competition
 
    The medical device industry  and the market  for treatment of  gynecological
disorders   and  infertility,  in  particular,  are  intensely  competitive  and
characterized  by   rapidly  evolving   technology.  Compared   to   traditional
 
                                       45
<PAGE>
laparoscopes   and  hysteroscopes,  the  Company  believes  that  the  principal
competitive factors  are  product  performance,  cost-effectiveness,  degree  of
invasiveness,  patient recovery  time and level  of side  effects. The Company's
proprietary  micro-optics   technology   provides  visualization   and   product
performance  comparable to traditional laparoscopes  and hysteroscopes, and when
used in combination with  the Company's micro-access  devices are less  invasive
than  products used in traditional laparoscopy and hysteroscopy procedures. As a
result, the  Company's systems  can  be used  without general  anesthesia,  thus
reducing  patent recovery time  and risk of  complications. Imagyn believes that
less-invasive procedures  performed with  the Company's  MicroLap and  MicroSpan
systems  will be  substantially less  traumatic and  costly than  more invasive,
traditional surgical procedures currently in widespread use.
 
    Competition in  the market  for micro-invasive  diagnosis and  treatment  of
gynecological  disorders is  intense and  is expected  to increase.  The Company
believes  that   the  principal   competitive  factors   in  the   markets   for
microlaparoscopes  and microhysteroscopes are  quality of visualization, product
performance, durability and compatibility  with capital equipment already  owned
by  the user. The  Company believes that  it competes favorably  with respect to
each of these  factors, particularly  with regard to  visualization and  product
performance.  A  number of  the  Company's competitors  are  currently marketing
products for use in such less-invasive procedures. Olympus America, Inc., Origin
Medsystems, Inc., a  subsidiary of Guidant  Corporation, Medical Dynamics,  Inc.
and  Karl  Storz  Instrument  Co.,  are  currently  marketing  laparoscopes with
diameters ranging from  1.2 millimeters to  3.0 millimeters. Circon-Cabot  Corp.
currently markets a microhysteroscope.
 
    Competition  in the market for falloposcopy and tubal recanalization is also
expected to increase. Conceptus,  Inc. is currently pursuing  FDA approval of  a
guidewire-based  falloposcopy system.  The Company  believes that  the principal
competitive factors in this  market will be product  performance and ability  to
perform  procedures  in a  non-hospital setting  without  the concurrent  use of
laparoscopy. The Company believes it competes favorably with respect to each  of
these factors.
 
    The  Company  also  faces  potential  competition  from  medical  device  or
pharmaceutical manufacturers that  currently market or  may be developing  other
medical  devices  or drugs,  such as  hormonal therapies,  for the  treatment of
uterine disorders. Other companies may choose to enter these markets at a  later
date  and would represent competition for  the Company. In addition, the Company
competes with other companies for sites to conduct clinical trials.
 
    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
any which have been or are being  developed by the Company or that would  render
the Company's technologies or products obsolete or not competitive, or that such
competitors  will not succeed in  obtaining regulatory approval for, introducing
or commercializing  any such  products prior  to the  Company. There  can be  no
assurance  that  the  Company  will  be able  to  compete  successfully  or that
competition will not have a material  adverse effect on the Company's  business,
financial condition or results of operations.
 
Product Liability and Insurance
 
    The  development, manufacture and sale of medical devices entail significant
risk of financial exposure to product liability claims. 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  maintains product  liability
insurance  with  coverage  limits of  $5,000,000  per occurrence  and  an annual
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 such coverage limits are adequate to protect  the
Company  from any liabilities it might incur in connection with the development,
manufacture and sale of its  products. Product liability insurance is  expensive
and in the future may not be available to the Company 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  could have a material  adverse
effect on the Company's business, financial condition and results of operations.

Employees
 
    As  of April 15,  1996, Imagyn had  58 full-time employees,  11 of whom were
engaged in research and  development activities, six  in regulatory and  quality
assurance, 23 in manufacturing, ten in sales and marketing, and eight in finance
and  administration.  None  of Imagyn's  employees  is covered  by  a collective
bargaining agreement, and the Company believes that it maintains good  relations
with its employees.
 
Facilities
 
    The  Company recently expanded  its facilities in  Laguna Niguel, California
with the lease  of an  additional 11,000 square  foot facility  adjacent to  the
Company's  current 16,000  square foot  facility. These  facilities comprise the
Company's administrative offices and manufacturing and warehouse operations. The
leases for these facilities extend through 1998. Imagyn believes that this space
is adequate for its current needs, and that it will be able to renew its  leases
and obtain additional space if necessary.
 
Legal Proceedings
 
    The Company is not currently a party to any legal proceedings.

Board of Directors
 
    Currently, all  directors  hold office  until  the next  annual  meeting  of
stockholders  or until  their successors  have been  elected and  qualified. The
Company's  Certificate  of  Incorporation,  however,  provides  that  upon   the
effective  date of this Offering, the Board of Directors, without further action
by the stockholders, will be divided into three classes. Each class of directors
will consist of one or two directors;  Class I, II and III directors will  serve
for  one, two or three year periods, respectively, or until their successors are
elected and qualified. Thereafter, directors will serve for staggered three year
terms. See "Description of Capital Stock--Certain Change of Control Provisions."
 
    The Board of Directors has  a Compensation Committee, consisting of  Messrs.
Colella  and  Schneider,  which makes  recommendations  concerning  salaries and
incentive  compensation  for  employees  of  the  Company  and  administers  the
Company's  equity incentive plans, and an Audit Committee, consisting of Messrs.
Chonette and Schneider,  which reviews the  results and scope  of the audit  and
other  services provided by  the Company's independent  accountants. Until March
1996, Mr.  Brown, the  President and  Chief Executive  Officer of  the  Company,
served  as  a  member  of  the  Compensation  Committee.  There  are  no  family
relationships among any of the directors or executive officers of the Company.
 
    Each officer is  elected by and  serves at  the discretion of  the Board  of
Directors.  Each of the Company's officers and directors, other than nonemployee
directors, devotes substantially full  time to the affairs  of the Company.  The
Company's  nonemployee directors devote such time  to the affairs of the Company
as is necessary  to discharge their  duties. There are  no family  relationships
among any of the directors, officers or key employees of the Company.
 
Compensation of Directors
 
    Directors  do not currently  receive any cash  compensation from the Company
for their  service as  members of  the  Board of  Directors, although  they  are
reimbursed  for certain expenses incurred in connection with their attendance at
Board and Committee meetings. However, the Company has entered into an agreement
with Elizabeth B. Connell, M.D., a director of the Company, which provides for a
minimum annual payment of $15,000 for Dr. Connell's attendance at board meetings
and other Company  related activities. Dr.  Connell has received  a grant of  an
option  to purchase  an aggregate  of 8,101  shares of  Common Stock.  Under the
Company's 1996 Director Option Plan, each  director who is not also an  employee
of  the Company (an "Outside Director")  will automatically receive an option to
purchase 15,000 shares of  Common Stock on  the date of  this Prospectus or,  if
later, upon
 
                                       50
<PAGE>
joining the Board of Directors. In addition, beginning on the first business day
of  1997, and each year thereafter, each  Outside Director who has served on the
Board of Directors for at least the preceding six months and continues to  serve
as  a director on the date  of such grant will be  granted an option to purchase
5,000 shares of Common Stock. See "--Stock Plans."
 
Compensation Committee Interlocks and Insider Participation
 
    The  Compensation  Committee  is   responsible  for  determining   salaries,
incentive  compensation and other forms  of compensation for directors, officers
and other employees of the Company. The Compensation Committee also  administers
various  incentive compensation  plans. The  Compensation Committee  consists of
Messrs. Colella and Schneider. Mr. Brown, who is the Company's President,  Chief
Executive Officer and Chairman of the Board, participates in all discussions and
decisions regarding salaries and incentive compensation for all employees of and
consultants  to the Company, except that  Mr. Brown is excluded from discussions
regarding his own salary and incentive compensation. Until March 1996, Mr. Brown
served as a member of the Compensation Committee.

Stock Option Information
 
    The  following table sets forth certain information concerning stock options
granted during the fiscal  year ended December 31,  1995 to the Named  Executive
Officers  under the Company's 1995 Stock  Plan. Options were also granted during

appreciation  of 5% and 10%, compounded annually. These amounts do not represent
the Company's estimate of future stock price. Actual realizable values, if  any,
of stock options will depend on the future performance of the Common Stock.

(1) Certain information about the individuals named in footnote 1 to the Summary
    Compensation  Table is  provided below: In  January 1996, Susan  E. Dube was
    granted an option  to purchase 67,504  shares of Common  Stock at $0.22  per
    share.  In  September 1995,  Kristine  F. Lahman  was  granted an  option to
    purchase 47,253 shares of  Common Stock at $0.22  per share. Ms. Lahman  was
    also  granted an  option to  purchase 10,801  shares of  Common Stock  at an
    exercise price of $3.70  per share under the  Company's 1990 Option Plan  in
    June 1995. Such option was cancelled pursuant to the Recapitalization.
 
(2) Options  were granted under the Company's 1995 Stock Plan and generally vest
    over four years from the date of commencement of employment. Mr. Woker's and
    Mr. MacRae's options vest over 36 months.
 
(3) Based on an aggregate of 560,696 options granted by the Company in the  year
    ended December 31, 1995 under the Company's 1995 Stock Plan to all employees
    of  and consultants to the Company,  including the Named Executive Officers.
    The Company also granted 29,635 options in the year ended December 31,  1995
    under  the 1990 Option Plan. All  unexercised options ever granted under the
    1990 Option Plan  were cancelled  in August 1995,  except for  an option  to
    purchase 40,833 shares held by Glen French, a former officer and director of
    the  Company, which option was exercised in March 1996. As of April 1, 1996,
    there were no options outstanding under the 1990 Option Plan.
 
(4) The exercise price per  share of each  option was equal  to the fair  market
    value of the Common Stock on the date of grant as determined by the Board of
    Directors.
 
(5) The potential realizable value is calculated based on the term of the option
    at  its time of grant  (ten years). It is  calculated assuming that the fair
    market value  of  Common Stock  on  the date  of  grant appreciates  at  the
    indicated  annual rate compounded annually for the entire term of the option
    and that the option is  exercised and sold on the  last day of its term  for
    the appreciated stock price.

Stock Plans
 
    1995  STOCK PLAN.  The Company's 1995 Stock Plan (the "1995 Stock Plan") was
adopted by the Board of Directors and approved by the stockholders in  September
1995.  The 1995 Stock Plan  was amended by the Board  of Directors in April 1996
and approved by the stockholders in May  1996. The 1995 Stock Plan replaced  the
1990 Option Plan, which was terminated pursuant to the Recapitalization. A total
of  1,675,000 shares of Common Stock have been authorized for issuance under the
1995 Stock  Plan. As  of April  1, 1996,  options to  purchase an  aggregate  of
665,059  shares were outstanding,  328,069 shares had been  issued pursuant to a
grant of a restricted stock purchase award and 681,872 shares were available for
future grant.  As  of  April  1,  1996, there  were  no  options  authorized  or
outstanding  under the 1990  Option Plan. The  1995 Stock Plan  provides for the
grant of  incentive stock  options within  the  meaning of  Section 422  of  the
Internal  Revenue  Code of  1986, as  amended  (the "Code"),  nonqualified stock
options and stock purchase rights to  employees and consultants of the  Company.
Incentive stock options may be granted only to employees. The 1995 Stock Plan is
administered  by a  committee of  the Board  of Directors,  which determines the
terms of awards  granted, including  recipient, type of  award, exercise  price,
number  of shares  subject to the  award and  vesting terms. No  employee may be
granted an option or options to purchase more than 750,000 shares in any  fiscal
year.
 
    The  exercise price of incentive stock  options granted under the 1995 Stock
Plan must be at  least equal to  the fair market value  of the Company's  Common
Stock  on the  date of grant.  The exercise  price of an  incentive stock option
granted to an employee  holding more than  10% of the  outstanding stock of  the
Company  must be at least  110% of the fair market  value. The exercise price of
nonqualified stock options is  set by the administrator  of the 1995 Stock  Plan
and  must be no less than  85% of the fair market  value of the Company's Common
Stock on the date of grant. The maximum term of an option granted under the 1995
Stock Plan is 10 years. In the event of a
 
                                       53
<PAGE>
merger of the Company  with or into  another corporation or the  sale of all  or
substantially  all of the assets of the  Company, each outstanding option may be
assumed or an equivalent option may be substituted by the successor corporation,
or a parent or subsidiary of such  successor corporation. If, in such event,  an
option  is not assumed or substituted, the option shall become fully exercisable
prior to the closing of the merger.
 
    Restricted stock purchase awards  granted under the 1995  Stock Plan may  be
granted  subject to a  repurchase option in  favor of the  Company in accordance
with a  service vesting  schedule  determined by  the  Board of  Directors.  The
purchase price for shares repurchased pursuant to the repurchase option shall be
the original price paid by the
purchaser.
 
    1996  DIRECTOR OPTION  PLAN.  The  Company's 1996 Director  Option Plan (the
"Director Plan")  was  adopted by  the  Board of  Directors  in April  1996  and
approved  by the stockholders in  May 1996. A total  of 200,000 shares of Common
Stock have been authorized for issuance to the directors of the Company pursuant
to nonstatutory stock options under the Director Plan. Under the Director  Plan,
each  director who  is not  also an  employee of  the Company  (each an "Outside
Director") will automatically  receive an  option to purchase  15,000 shares  of
Common Stock (the "Initial Option") on the date of this Prospectus or, if later,
upon joining the Board of Directors. Beginning on the first business day of 1997
and  continuing on the first business day  of each year thereafter, each Outside
Director will receive an annual grant of  an option to purchase 5,000 shares  of
Common Stock (the "Subsequent Option"), provided the Outside Director has served
as  an Outside Director for  at least the preceding  six months and continues to
serve as a director  on the date of  such grant. The exercise  price of each  of
these  options will be equal to the fair market value of the Common Stock on the
date of grant. Each option granted under the Director Plan shall be  exercisable
only  while the Outside Director remains a director of the Company. Each Initial
Option and each  Subsequent Option  will vest monthly  over four  years. In  the
event of a merger of the Company with or into another corporation or the sale of
all  or substantially all of the assets of the Company, outstanding options must
be assumed  by any  surviving or  successor corporation  or its  parent, or  all
options   granted  under  the  Director  Plan   will  become  fully  vested  and
exercisable. Options granted under the Director Plan and assumed by a  surviving
or  successor corporation or its parent will become fully vested and exercisable
if  the  optionee's  status  as  a  director  of  such  surviving  or  successor
corporation  or parent  is terminated other  than upon  the optionee's voluntary
resignation. The maximum term of options granted under the Director Plan is  ten
years.  The Director  Plan shall  be in effect  for a  term of  ten years unless
terminated earlier pursuant to its terms.
 
    1996 EMPLOYEE  STOCK  PURCHASE PLAN.    The Company's  1996  Employee  Stock
Purchase  Plan (the "Purchase  Plan") was adopted  by the Board  of Directors in
April 1996 and  approved by the  stockholders in  May 1996. A  total of  200,000
shares  of Common  Stock have  been authorized  for issuance  under the Purchase
Plan. No shares  have been issued  under the Purchase  Plan. The Purchase  Plan,
which is intended to qualify under Section 423 of the Code, will be administered
by  the Board  of Directors of  the Company or  by a committee  appointed by the
Board of  Directors.  Under the  Purchase  Plan,  the Company  will  withhold  a
specified percentage (not to exceed 10%) of each salary payment to participating
employees  over certain offering periods. Any employee who is currently employed
for at  least 20  hours per  week  for at  least five  consecutive months  in  a
calendar  year, either by the  Company or by a  majority-owned subsidiary of the
Company, will be eligible to participate in the Purchase Plan. Unless the  Board
of  Directors or its  committee determines otherwise,  each offering period will
run for 24 months and will be divided into four consecutive purchase periods  of
approximately  six  months. The  first offering  period  and the  first purchase
period will  commence on  the date  of this  Prospectus. New  24-month  offering
periods  will commence approximately  every six months  thereafter. The price at
which Common Stock will be purchased under the Purchase Plan is equal to 85%  of
the  fair market value  of the Common Stock  on the first  day of the applicable
offering period or the last day of the applicable purchase period, whichever  is
lower.  Employees may end their participation in the offering at any time during
the offering  period, and  participation ends  automatically on  termination  of
employment  with  the  Company. The  number  of  shares that  a  participant may
purchase in any purchase period is determined by dividing the payroll deductions
accumulated during the purchase period by the purchase price. However, no person
may purchase shares under the Purchase Plan to the extent such person would  own
5%  or more of  the total combined value  or voting power of  all classes of the
capital stock of the  Company or of  any of its subsidiaries,  or to the  extent
that  such person's rights  to purchase stock under  all employee stock purchase
plans would  accrue at  a  rate that  exceeds $25,000  worth  of stock  for  any
calendar year, determined as of the first day of the applicable offering period.
In the event of a merger of the Company with or into another corporation, or the
sale of all or substantially all of the
 
                                       54
<PAGE>
assets  of the Company, the offering period  then in progress will be shortened.
The Board may amend the Purchase Plan at any time. The Purchase Plan shall be in
effect for a term of ten years unless terminated earlier pursuant to its terms.
 
Incentive Bonus Plan
 
    The Company's Board of  Directors has approved  a 1996 Management  Incentive
Bonus  program ("Bonus  Plan") for  officers and  other eligible  employees. The
Bonus Plan provides for bonuses of up to 20% of base compensation, provided that
certain specific performance criteria are met. No bonuses are payable unless the
Company achieves 200% or more of  the combined percentage of its 1996  Operating
Plan revenues and operating profit.
 
Section 401(k) Plan
 
    The  Company  has  established  a 401(k)  plan  and  provides administrative
services under the plan without charge to those employees who participate in the
plan. The plan is entirely self-contributory  and the Company does not make  any
contributions on behalf of participants.
 
Limitations on Directors' Liability and Indemnification
 
    The Company's Certificate of Incorporation limits the liability of directors
to  the maximum  extent permitted  by Delaware  law. Delaware  law provides that
directors of a corporation  will not be personally  liable for monetary  damages
for  breach of their fiduciary duties as directors, except liability for (i) any
breach of their  duty of loyalty  to the corporation  or its stockholders,  (ii)
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) unlawful payments of dividends or unlawful stock
repurchases  or redemptions,  or (iv)  any transaction  from which  the director
derived an  improper personal  benefit. Such  limitation of  liability does  not
apply  to liabilities  arising under  the federal  securities laws  and does not
affect the  availability of  equitable  remedies such  as injunctive  relief  or
rescission.
 
    The  Company's Bylaws provide that the Company shall indemnify its directors
and executive officers and  may indemnify its other  officers and employees  and
other  agents to the fullest extent permitted  by law. The Company believes that
indemnification under its Bylaws covers at least negligence and gross negligence
on the  part of  indemnified parties.  The Company's  Bylaws also  permit it  to
secure insurance on behalf of any officer, director, employee or other agent for
any  liability arising out of his or her actions in such capacity, regardless of
whether the Bylaws permit such indemnification.
 
    The Company  has entered  into  agreements to  indemnify its  directors  and
executive  officers,  in addition  to the  indemnification  provided for  in the
Company's Bylaws. These agreements, among other things, indemnify the  Company's
directors  and  executive officers  for  certain expenses  (including attorneys'
fees), judgments, fines and  settlement amounts incurred by  any such person  in
any  action or proceeding, including any action by or in the name of the Company
arising out of such person's services as a director or executive officer of  the
Company,  any subsidiary of  the Company or  any other company  or enterprise to
which the person provides  services at the request  of the Company. The  Company
believes  that  these provisions  and agreements  are  necessary to  attract and
retain qualified persons as directors and executive officers.
 
    At present,  there  is  no  pending litigation  or  proceeding  involving  a
director  or  officer of  the Company  in which  indemnification is  required or
permitted and  the  Company  is  not  aware  of  any  threatened  litigation  or
proceeding that may result in a claim for such indemnification.

                              CERTAIN TRANSACTIONS
 
    In  September 1995,  the Company  completed an  equity recapitalization (the
"Recapitalization").  The   following   events   occurred   as   part   of   the
Recapitalization:  (i) the  conversion of  all outstanding  shares of  Series A,
Series B  and  Series  C  Preferred  Stock  (together  constituting  the  "Prior
Preferred")  on a  1-for-1 basis  into shares  of Common  Stock, (ii)  a reverse
1-for-5 split of  all outstanding Common  Stock and options  to purchase  Common
Stock, (iii) the issuance of 2,153,484 shares of New Series A Preferred Stock at
$3.66  per  share, (iv)  the conversion  of  outstanding bridge  financing notes
totaling $2,056,586 into 562,062 shares of new Series A Preferred Stock, (v) the
conversion of bridge financing warrants into 281,034 shares of Common Stock, and
(vi) amendments to the stock option plans.
 
    During 1995, the Company obtained  $2,056,586 in bridge note financing  from
several of its stockholders. Interest at the rate of prime plus 1%, and totaling
$59,468,  was  paid in  cash.  In addition,  the  Company granted  a  warrant to
purchase a share of the new Series  A Preferred Stock with an exercise price  of
$3.66  per share for each two shares of  new Series A Preferred Stock into which
the bridge financing  notes were convertible.  Warrants to purchase  a total  of
281,034  shares of  new Series  A Preferred Stock  were so  granted (the "Bridge
Financing Warrants"). Such Bridge Financing Warrants were exchanged for  281,034
shares  of  Common  Stock  for  no  additional  consideration  as  part  of  the
Recapitalization.
 
    The  following  entities  affiliated  with  directors  and  5%  stockholders
exchanged  indebtedness for  new Series A  Preferred Stock  and exchanged Bridge
Financing Warrants for shares of Common Stock and paid cash as indicated below:

    In October 1994, the Company issued 45,903 shares to Franklin D. Brown,  the
President,  Chief Executive  Officer and  Chairman of the  Board, at  a price of
$3.70 per  share in  exchange for  a $170,000  promissory note  executed by  Mr.
Brown.  Such shares were repurchased  by the Company in  August 1995 in exchange
for cancellation of the $170,000 promissory note executed by Mr. Brown. Also  in
October  1994, Mr. Brown was granted options to purchase 20,252 shares of Common
Stock at an exercise price of $3.70  per share. Those options were cancelled  as
part of the Recapitalization.
 
    In  October 1995,  the Company  sold 328,069 shares  of Common  Stock to Mr.
Brown at  a  purchase  price of  $0.22  per  share in  exchange  for  a  $72,900
promissory  note executed by Mr. Brown pursuant to a stock purchase agreement. A
separate agreement  dated  April 1996  provided  the  Company with  a  right  to
repurchase such shares, at a price of $0.22 per share. The promissory note bears
interest  at 6.31% per annum with all  principal and interest due on October 30,
2000. The promissory  note is  collateralized by  the related  shares of  Common
Stock.  The repurchase  option, which matches  the vesting terms  of the shares,
expires with  respect to  35%  of the  shares in  September  1996 and,  for  the
remaining shares, on a monthly pro rata basis through September 1998.
 
    The  Company has  entered into  an agreement  dated March  1996 with  Guy R.
Lowery, a former officer  and director of the  Company. The agreement  includes,
among  other matters, provisions regarding resignation, consulting services, and
certain amendments  to a  pledge agreement  made in  connection with  a  secured
promissory note for $75,000 collateralized by 47,253 shares of Common Stock. The
agreement provides for the repayment of the principal of and accrued interest on
the  promissory note with  shares of Common  Stock, and in  connection with such
repayment, for the repurchase by the Company of 7,585 shares of Common Stock  at
$11.00 per share.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 50,000,000 shares of
Common Stock and 5,000,000 shares of Preferred Stock, after giving effect to the
restatement  of the Company's  Certificate of Incorporation  upon the closing of
this Offering. The following summaries of certain provisions of the Common Stock
and Preferred  Stock do  not purport  to be  complete and  are subject  to,  and
qualified  in their entirety by, the  provisions of the Company's Certificate of
Incorporation, which is included as an exhibit to the Registration Statement  of
which this Prospectus forms a part, and by applicable law.
 
Common Stock
 
    As  of  April  15,  1996,  there  were  4,744,155  shares  of  Common  Stock
outstanding held by 47 stockholders of record.
 
    The holders  of Common  Stock are  entitled to  one vote  per share  on  all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable  to any outstanding Preferred Stock,  the holders of Common Stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time  by the  Board of  Directors out  of funds  legally available  for  that
purpose.  See "Dividend Policy."  In the event of  a liquidation, dissolution or
winding up of the  Company, the holders  of Common Stock  are entitled to  share
ratably  in all assets remaining after  payment of liabilities, subject to prior
distribution rights of  Preferred Stock,  if any, then  outstanding. The  Common
Stock has no preemptive or conversion rights or other subscription rights. There
are no redemption or sinking fund provisions applicable to the Common Stock. All
outstanding  shares of  Common Stock are  fully paid and  nonassessable, and the
shares of Common Stock to  be issued upon the closing  of this Offering will  be
fully paid and nonassessable.
 
Preferred Stock
 
    The   Board  of  Directors   has  the  authority,   without  action  by  the
stockholders, to designate and  issue shares of Preferred  Stock in one or  more
series  and to designate the rights,  preferences and privileges of each series,
any or all of which may  be greater than the rights  of the Common Stock. It  is
not  possible  to state  the  actual effect  of the  issuance  of any  shares of
Preferred Stock upon the rights of holders  of the Common Stock until the  Board
of  Directors determines  the specific rights  of the holders  of such Preferred
Stock. However,  the  effects might  include,  among other  things,  restricting
dividends  on the Common Stock,  diluting the voting power  of the Common Stock,
impairing the liquidation rights of the Common Stock and delaying or  preventing
a  change in control of the Company  without further action by the stockholders.
The Company has no present plans to issue any shares of Preferred Stock.
 
Reincorporation in Delaware
 
    The Company intends  to reincorporate  in Delaware in  connection with  this
Offering.  The Company believes  that Delaware law  provides flexibility and the
Delaware  courts  have  particular  expertise  with  matters  affecting   public
companies  and their stockholders. Except as otherwise noted, all information in
the Prospectus assumes the reincorporation has occurred.
 
Registration Rights of Certain Holders
 
    The  holders  of  4,102,223  shares   of  Common  Stock  (the   "Registrable
Securities") or their transferees are entitled to certain rights with respect to
the  registration  of such  shares under  the Securities  Act. These  rights are
provided under the terms of an agreement between the Company and the holders  of
Registrable  Securities. Subject  to certain  limitations in  the agreement, the
holders of  at least  40% of  the  Registrable Securities  may require,  on  two
occasions  after December  31, 1996,  that the Company  use its  best efforts to
register the Registrable Securities for public resale. If the Company  registers
any  of its Common Stock either for its  own account or for the account of other
security holders, the holders of Registrable Securities are entitled to  include
their  shares of Common Stock in the registration, subject to the ability of the
underwriters to limit the number of shares included in the offering (but to  not
less  than 25% of the offering). The holders  of at least 20% of the Registrable
Securities may also require the Company, on four occasions to register all or  a
portion  of  their Registrable  Securities on  Form  S-3 when  use of  such form
becomes available to the  Company, provided, among  other limitations, that  the
proposed aggregate selling
 
                                       60
<PAGE>
price  (net  of any  underwriters' discounts  or commissions)  is at  least $1.0
million. All registration expenses must be borne by the Company and all  selling
expenses  relating to Registrable Securities must be borne by the holders of the
securities being registered.
 
Delaware Law and Certain Charter Provisions
 
    The Company is a Delaware corporation and  is subject to Section 203 of  the
Delaware  General Corporation Law, an anti-takeover law. In general, Section 203
prohibits a  publicly held  Delaware corporation  from engaging  in a  "business
combination"  with  an  "interested stockholder"  for  a period  of  three years
following the date  the person  became an interested  stockholder, unless  (with
certain  exceptions) the "business combination" or  the transaction in which the
person became  an interested  stockholder is  approved in  a prescribed  manner.
Generally,  a "business combination" includes a  merger, asset or stock sale, or
other  transaction  resulting   in  a  financial   benefit  to  the   interested
stockholder.  Generally, an "interested  stockholder" is a  person who, together
with affiliates  and  associates, owns  (or  within  three years  prior  to  the
determination  of  interested stockholder  status,  did own)  15%  or more  of a
corporation's voting stock. The existence of this provision would be expected to
have an  anti-takeover  effect with  respect  to transactions  not  approved  in
advance by the Board of Directors, including discouraging takeover attempts that
might  result in a premium over the market  price for the shares of Common Stock
held by stockholders.
 
    The Company's  Certificate  of Incorporation  will  provide that,  upon  the
closing  of this  Offering, the  Board of Directors  will be  divided into three
classes of directors with  each class serving a  staggered three-year term.  The
classification system of electing directors may tend to discourage a third party
from  making a  tender offer  or otherwise attempting  to obtain  control of the
Company and  may maintain  the incumbency  of  the Board  of Directors,  as  the
classification  of the Board of Directors  generally increases the difficulty of
replacing  a  majority   of  the   directors.  The   Company's  Certificate   of
Incorporation  will also eliminate  the right of stockholders  to act by written
consent without a meeting.  The Certificate of Incorporation  and Bylaws do  not
provide for cumulative voting in the election of directors. The authorization of
undesignated  Preferred Stock  makes it possible  for the Board  of Directors to
issue Preferred Stock  with voting  or other  rights or  preferences that  could
impede  the success of any  attempt to change control  of the Company. These and
other provisions may have the effect of delaying or preventing hostile takeovers
or delaying changes in  control or management of  the Company. The amendment  of
any of these provisions would require approval by holders of at least 66 2/3% of
the outstanding Common Stock.
 
Transfer Agent and Registrar
 
    The  transfer  agent and  registrar  for the  Common  Stock is  Norwest Bank
Minnesota, N.A. Its telephone number is (800) 468-9716.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this Offering, there has been no market for the Common Stock of the
Company. Future  sales of  substantial amounts  of Common  Stock in  the  public
market  could  adversely  affect market  prices  prevailing from  time  to time.
Furthermore, since only a  limited number of shares  will be available for  sale
shortly   after  this  Offering   because  of  certain   contractual  and  legal
restrictions on resale  (as described  below), sales of  substantial amounts  of
Common  Stock of the Company  in the public market  after the restrictions lapse
could adversely  affect the  prevailing  market price  and  the ability  of  the
Company to raise equity capital in the future.
 
    Upon the completion of this Offering, the Company will have 7,244,155 shares
of  Common Stock  outstanding, assuming  no exercise  of options  after April 1,
1996. Of these outstanding shares of Common Stock, the 2,500,000 shares sold  in
this  Offering will be freely tradable  without restriction under the Securities
Act, unless purchased by "affiliates" of the Company, as that term is defined in
Rule 144 under  the Securities  Act. The  remaining 4,744,155  shares of  Common
Stock  held by existing stockholders are "restricted securities" as that term is
defined in Rule 144 under  the Securities Act, and were  issued and sold by  the
Company  in reliance  on exemptions  from the  registration requirements  of the
Securities Act. These shares may be sold in the public market only if registered
or pursuant to an exemption from registration,  such as Rule 144, 144(k) or  701
under the Securities Act.
 
    All holders of Common Stock and options to purchase Common Stock have agreed
pursuant  to certain lock-up agreements that they will not offer, sell, contract
to  sell,  grant  any  option  to   sell  or  otherwise  dispose  of,   directly
 
                                       61
<PAGE>
or  indirectly,  any shares  of  Common Stock  owned by  them  or that  could be
purchased by them through  the exercise of options  to purchase Common Stock  of
the  Company for a period of 180 days  after the date of this Prospectus without
the prior written consent  of Dillon, Read  & Co. Inc.  The Company has  entered
into  a similar agreement, except  that the Company may  grant options and issue
stock under its current  stock option and stock  purchase plans and pursuant  to
other currently outstanding options.
 
    Assuming  no  shares are  released from  the  lock-up agreements  before the
180-day period, upon  such expiration,  approximately 713,811  shares of  Common
Stock   held  by  existing  stockholders  will  be  eligible  for  sale  without
restriction pursuant to  Rule 144(k)  or Rule 701,  and approximately  1,020,112
shares  held by existing stockholders  will be eligible for  sale subject to the
volume and other restrictions of Rule  144. The remaining 3,010,232 shares  held
by existing stockholders will become eligible for sale pursuant to Rule 144 upon
the  expiration  of  their two-year  holding  periods. 4,102,223  of  the shares
outstanding immediately  following  the  completion of  this  Offering  will  be
entitled  to registration rights with respect to such shares upon the release of
lock-up agreements.  The  number of  shares  sold  in the  public  market  could
increase if such rights are exercised.
 
    As of April 1, 1996, 665,059 shares were subject to outstanding options. All
of  these  shares  are  subject  to  the  lock-up  agreements  described  above.
Approximately 30 days after the date of this Prospectus, the Company intends  to
file  a Registration Statement on Form S-8 to register all shares issuable under
the Company's  1995 Stock  Plan (including  shares subject  to then  outstanding
options  under such  plans), 1996 Director  Option Plan and  1996 Employee Stock
Purchase Plan, thus permitting the resale  of such shares in the public  market,
subject  to  Rule  144  volume  limitations  applicable  to  affiliates, without
restriction under the Securities Act after expiration of the applicable  lock-up
agreements.  Upon  the expiration  of  such lock-up  agreements,  244,168 shares
subject to such options will be vested.
 
    In general, under  Rule 144  as currently in  effect, a  person (or  persons
whose  shares are aggregated) who has beneficially owned shares for at least two
years (including the holding period of any prior owner, except an affiliate)  is
entitled  to sell in a  "broker's transaction" or to  a market maker, within any
three-month period  commencing 90  days after  the date  of this  Prospectus,  a
number  of shares  that does not  exceed the greater  of (i) one  percent of the
number of shares of Common  Stock then outstanding (approximately 73,000  shares
immediately  after this Offering)  or (ii) the average  weekly trading volume of
the Common Stock during the four calendar weeks preceding the required filing of
a Form 144 with respect to such sale. Sales under Rule 144 are generally subject
to certain  manner  of  sale  provisions and  notice  requirements  and  to  the
availability of current public information about the Company. Under Rule 144(k),
a  person who is not deemed to have been an affiliate of the Company at any time
during the 90 days preceding a sale,  and who has beneficially owned the  shares
proposed  to be sold for  at least three years, is  entitled to sell such shares
without having to  comply with the  manner of sale,  public information,  volume
limitation  or  notice  provisions of  Rule  144.  Under Rule  701,  persons who
purchase shares upon exercise of options granted prior to the effective date  of
this  Offering are entitled to sell such shares 90 days after the effective date
of this Offering  in reliance on  Rule 144,  without having to  comply with  the
holding  period requirements  of Rule  144 and,  in the  case of non-affiliates,
without having  to comply  with  the public  information, volume  limitation  or
notice provisions of Rule 144.
 
    The  Securities and Exchange  Commission has recently  proposed reducing the
Rule 144 holding period to  one year and the Rule  144(k) holding period to  two
years. There can be no assurance as to when or whether such rule changes will be
enacted. If enacted, such modifications will have a material effect on the times
when shares of the Company's Common Stock become eligible for resale.

</TABLE>
 
    The Managing  Underwriters  are  Dillon,  Read &  Co.  Inc.  and  Montgomery
Securities.
 
    If  any of the  shares of Common  Stock offered hereby  are purchased by the
Underwriters, all such shares will  be so purchased. The Underwriting  Agreement
contains   certain  provisions  whereby  if  any  Underwriter  defaults  in  its
obligation to  purchase such  shares and  if the  aggregate obligations  of  the
Underwriters  so defaulting do not exceed 10%  of the shares offered hereby, the
remaining Underwriters, or some of them, must assume such obligations.
 
    The shares of Common Stock offered hereby are being offered severally by the
Underwriters for sale at  the price set  forth on the cover  page hereof, or  at
such  price less a  concession not to  exceed $   per share on  sales to certain
dealers. The Underwriters may allow, and such dealers may reallow, a  concession
not  to exceed $  per  share on sales to certain  other dealers. The offering of
the shares of Common Stock is made for delivery when, as, and if accepted by the
Underwriters and  subject  to prior  sale  and to  withdrawal,  cancellation  or
modification  of the offer without notice. The Underwriters reserve the right to
reject any order for the purchase of  the shares. After the shares are  released
for  sale  to the  public, the  public  offering price,  the concession  and the
reallowance may be changed by the Managing Underwriters.
 
    The Company has granted to the Underwriters  an option to purchase up to  an
additional  375,000 shares of Common  Stock on the same  terms per share. If the
Underwriters exercise this  option, each of  the Underwriters will  have a  firm
commitment,  subject to certain  conditions, to purchase  approximately the same
proportion of the aggregate shares  so purchased as the  number of shares to  be
purchased  by it shown in the above table bears to the total number of shares in
such table. The Underwriters may exercise such option on or before the thirtieth
day from the date of the public  offering of the shares offered hereby and  only
to cover over-allotments made of the shares in connection with this Offering.
 
    The  Company, its executive  officers and directors and  all of its existing
stockholders and optionholders have agreed that they will not, without the prior
written consent of Dillon, Read  & Co. Inc., sell,  contract to sell, grant  any
option  to sell, transfer  or otherwise dispose of,  directly or indirectly, any
shares of the Common Stock, or  any securities convertible into, or  exercisable
or exchangeable for, Common Stock or warrants or other rights to purchase Common
Stock,  prior to the expiration of 180 days from the date of the consummation of
this Offering, except  (i) shares of  Common Stock issued  upon the exercise  of
options  issued under  the Company's  existing stock  option plans  and (ii) the
grant of options  and other  rights to purchase  Common Stock  to the  Company's
employees, officers and directors under its existing stock option plans totaling
no more than an aggregate of 200,000 shares.
 
    The  Company  has  agreed  to  indemnify  the  Underwriters  against certain
liabilities,  including  any  liabilities  under  the  Securities  Act,  or   to
contribute  to  payments the  Underwriters may  be required  to make  in respect
thereof.

<PAGE>
    Prior to this  Offering, there was  no public market  for the Common  Stock.
Consequently,  the  initial  public  offering price  for  the  Common  Stock was
determined by negotiation  between the  Managing Underwriters  and the  Company.
Factors  considered in determining such price were prevailing market conditions,
the state of the Company's development, recent financial results of the Company,
the future  prospects of  the Company  and its  industry, market  valuations  of
securities   of  companies  engaged   in  activities  deemed   by  the  Managing
Underwriters to be  similar to those  of the Company,  and other factors  deemed
relevant.
 
    The  Underwriters do not intend to confirm sales to accounts over which they
exercise discretionary authority.
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for  the
Company  by  Wilson Sonsini  Goodrich &  Rosati, Professional  Corporation, Palo
Alto, California. Certain legal matters will be passed upon for the Underwriters
by Cooley Godward Castro  Huddleson & Tatum, Menlo  Park, California. As of  the
date  of this Prospectus,  certain members of Wilson  Sonsini Goodrich & Rosati,
Professional Corporation and investment partnerships  of which such persons  are
partners beneficially own 7,914 shares of the Company's Common Stock.

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

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  The Company:
    Imagyn  Medical, Inc. (the "Company") was  incorporated in 1989. The Company
designs, develops and  markets micro-invasive,  cost effective  devices for  the
diagnosis and treatment of gynecological and reproductive disorders.
 
    Imagyn International, Inc. was organized as a wholly-owned subsidiary of the
Company  in  1993.  Imagyn International,  Inc.  was created  to  facilitate the
marketing, sales and  distribution of  the Company's  products in  international
markets.
 
2.  Summary Of Significant Accounting Policies:
 
    PRINCIPLES OF CONSOLIDATION
 
    The  accompanying consolidated financial statements  include the accounts of
the Company  and  its  wholly-owned  subsidiary.  All  significant  intercompany
accounts and transactions have been eliminated in consolidation.
 
    REVENUE RECOGNITION
 
    Sales  and related cost of goods sold  are recognized when goods are shipped
to customers. The  majority of  the Company's customers  are distributors  which
sell  goods to third-party end-users. The Company is not contractually obligated
to repurchase  any  inventory  from  its distributors.  The  Company  records  a
warranty accrual at the time of sale for estimated claims.
 
    RESEARCH AND DEVELOPMENT COSTS
 
    Research and development costs are expensed as incurred.
 
    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of cash in banks, certificates of deposit,
and short-term investments with acquired maturities of three months or less. The
carrying amount of cash and cash equivalents approximates market value.
 
    SHORT-TERM INVESTMENTS
 
    The  short-term investments  are managed  by an  outside brokerage  firm and
consist primarily of commercial paper,  certificates of deposit, and  short-term
bond  instruments with  acquired maturities  of one  year or  less. The carrying
amount of short-term investments is the cost plus interest earned as of December
31, 1995, which approximates market value.
 
    RESTRICTED CASH
 
    The Company collateralized a letter of credit in the amount of $117,187 with
a certificate  of  deposit for  $131,000.  The  certificate of  deposit  has  an
interest  rate of 4.5%  and a maturity date  of June 30,  1996, and is therefore
classified as a current asset on the accompanying consolidated balance sheet.
 
    INVENTORIES
 
    Inventories are stated at the lower of cost or market, cost being determined
on the first-in, first-out (FIFO) basis.
 
    FURNITURE, FIXTURES AND EQUIPMENT
 
    Furniture, fixtures and equipment are  stated at cost and depreciated  using
the  straight-line method  over the estimated  useful lives of  the assets which
range from  three to  five  years. Leasehold  improvements  are amortized  on  a
straight-line  basis over  the lesser of  the term  of the related  lease or its
estimated useful life.
 
    Repairs  and  maintenance  are  expensed  as  incurred  while  renewals   or
betterments  are capitalized. Upon the sale or retirement of furniture, fixtures
and equipment, the accounts are relieved of the cost and the related accumulated
depreciation and amortization,  and any resulting  gain or loss  is included  in
operations.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
 
2.  Summary Of Significant Accounting Policies: (Continued)
    INCOME TAXES
 
    The  Company follows  Statement of  Financial Accounting  Standards No. 109,
"Accounting for Income Taxes,"  which requires the  recognition of deferred  tax
liabilities  and assets for the expected  future tax consequences of events that
have been  included in  the  financial statements  or  tax returns.  Under  this
method,  deferred income taxes are recognized for the tax consequences in future
years of differences between the tax  bases of assets and liabilities and  their
financial  reporting  amounts at  each year-end  based on  enacted tax  laws and
statutory rates applicable to the periods in which the differences are  expected
to  affect taxable income. Valuation allowances are established, when necessary,
to reduce  deferred  tax assets  to  the amount  expected  to be  realized.  The
provision  for income taxes  represents the tax  payable for the  period and the
change during the period in deferred tax assets and liabilities.
 
    COMMON STOCK OPTIONS
 
    In October 1995, the  Financial Accounting Standards  Board issued SFAS  No.
123,  "Accounting for  Stock-Based Compensation."  SFAS No.  123 defines  a fair
value based method of accounting for an employee stock option. Fair value of the
stock option is determined  by considering factors such  as the exercise  price,
the  expected life of the option, the  current price of the underlying stock and
its volatility, expected dividends on the stock and the risk-free interest  rate
for  the  expected  term of  the  option.  Under the  fair  value  based method,
compensation cost is measured as  of the grant date based  on the fair value  of
the  award and  is recognized over  the service  period. A company  may elect to
adopt SFAS No.  123 or  elect to  continue accounting  for its  stock option  or
similar  equity awards  using the intrinsic  method, where  compensation cost is
measured at the date  of grant based on  the excess of the  market value of  the
underlying  stock over the exercise price. If a company elects not to adopt SFAS
No. 123, then it must  provide pro forma disclosure  of net income and  earnings
per share, as if the fair value based method had been applied.
 
    SFAS  No. 123  is effective for  transactions entered into  for fiscal years
beginning after December 15, 1995. Pro forma disclosures for entities that elect
to continue to measure compensation cost under the intrinsic method must include
the effects of all awards granted in fiscal years that begin after December  15,
1994.  It is currently anticipated that the Company will continue to account for
stock-based compensation plans under the intrinsic method and the impact of SFAS
No. 123 has not yet been determined.
 
    ESTIMATES
 
    The  preparation  of  financial  statements  in  accordance  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
    INTERIM FINANCIAL INFORMATION
 
    The  financial information at March 31, 1996 and for the three month periods
ended March  31,  1995  and  1996 is  unaudited  but  includes  all  adjustments
(consisting  only of normal  recurring adjustments) which  the Company considers
necessary for a fair presentation of the financial position at such date and the
operating results and  cash flows for  those periods. Results  of the March  31,
1996 period are not necessarily indicative of the results for the entire year.
 
    RECLASSIFICATIONS
 
    Certain  reclassifications have been made to  the 1993 and 1994 consolidated
financial statements to conform to the 1995 presentation.
 
3.  Recapitalization:
    On September 8, 1995, the Company completed an equity recapitalization  (the
"Recapitalization").   The   following   events   occurred   as   part   of  the
Recapitalization: (i)  the conversion  of all  outstanding shares  of Series  A,
Series  B and Series C preferred stock on  a 1-for-1 basis into shares of common
stock, (ii) a reverse 1-for-5 split of all

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
 
3.  Recapitalization: (Continued)
then outstanding common stock  and common stock options,  (iii) the issuance  of
2,153,484  shares of new Series A Preferred stock at $3.66 per share for cash of
$7,879,395, (iv)  the  conversion  of  outstanding  bridge  financing  notes  of
$2,056,586  into 562,062 shares of new  Series A preferred stock, (v) conversion
of bridge  financing warrants  into 281,034  shares of  common stock,  and  (vi)
amendments to the stock option plans.
 
    Prior  to  the  completion  of the  Recapitalization,  the  Company obtained
$2,056,586 in bridge note financing. Interest at the rate of prime plus 1%,  and
totaling  $59,468, was paid in cash. In  addition, the Company granted a warrant
to purchase a share of the new Series A preferred stock for $3.66 per share, for
each two shares of new Series A preferred stock received after conversion of the
bridge financing  notes, or  total warrants  to acquire  281,034 shares  of  new
Series  A  preferred  stock  (the  "bridge  financing  warrants").  These bridge
financing warrants were later exchanged for  281,034 shares of common stock  for
no  additional consideration in the Recapitalization. The Company has recognized
a one-time non-cash charge  of $331,618 to interest  expense in connection  with
this  transaction, with such amount representing  the then fair market value, as
determined by an independent third-party valuation, of such shares.
 
    All share  and per  share amounts  have been  adjusted to  give  retroactive
effect to the reverse stock split for all periods presented.
 
4.  Related Party Transactions:
    During 1994, the Company sold 45,903 shares of common stock to an officer of
the  Company in exchange  for a $170,000 recourse  promissory note. These shares
were returned to the Company and the promissory note was canceled in August 1995
as part of the Company's Recapitalization. On October 31, 1995, the Company sold
328,069 shares of common  stock to the  same officer in  exchange for a  $72,900
recourse  promissory note. The promissory note bears interest at 6.31% per annum
with all principal and interest due on October 30, 2000. The promissory note  is
collateralized  by the related shares of common stock. The Company has an option
to repurchase  the shares  at $0.222  per share.  The repurchase  option,  which
matches  the vesting  terms of the  shares, expires  with respect to  35% of the
shares on September 7, 1996 and, for the remaining shares, on a monthly pro rata
basis through September 7, 1998.
 
    The Company has a License Agreement with two of its stockholders relating to
patents, patent applications  and other  know-how on  certain medical  equipment
technology. Royalties pursuant to the License Agreement are payable for a period
of  ten years following the date of  the first commercial sale or the expiration
date of the last applicable patent, whichever occurs later. For the years  ended
December 31, 1993, 1994 and 1995, total royalty expense under this agreement was
$14,226, $18,703 and $28,315, respectively.
 
    During  1993,  the  Company  loaned two  stockholders  $75,000  and $48,000,
respectively. The loans bear  interest at 4.92% and  5%, respectively, and  have
five-year  terms. The loans are collateralized by shares of the Company's common
stock. Subsequent to December 31, 1995,  terms of the $75,000 loan were  amended
to  provide for the payment of principal and interest on the earlier of: (i) the
date on which the  Company files a  registration statement on  Form S-1 for  the
sale of common stock, or (ii) June 30, 1996.
 
    During   1992,  the  Company  entered  into  a  License,  Manufacturing  and
Distribution Agreement (the "Agreement")  with Terumo Corporation ("Terumo"),  a
stockholder,  granting  Terumo  the  right  to  manufacture  and  distribute the
Company's products  in Japan.  Under  the terms  of  the Agreement,  Terumo  was
required  to  pay the  Company  $1.1 million,  nonrefundable,  for the  right to
distribute the Company's products in Japan and  $1 million as a license fee  for
the  right to manufacture certain  of the Company's products  for sale in Japan.
The Agreement also requires Terumo to pay royalties to the Company upon sales of
products manufactured by Terumo under the terms of the Agreement. The Company is
required to provide manufacturing know-how, training and documentation to Terumo
for the  purpose  of  establishing manufacturing  capability  relating  to  such
products  within two  years after Japanese  government approval  of the product,
which  was  obtained   in  August   1995.  In   the  event   the  Company   does

    At December 31, 1995, the Company  had net operating loss carryforwards  for
federal   and  state  purposes  of  approximately  $12,400,000  and  $5,900,000,
respectively. The net operating  loss carryforwards begin  expiring in 2005  and
1997,  respectively. The  Company also  has research  and experimentation credit
carryforwards for  federal  and state  purposes  of approximately  $560,000  and
$220,000, respectively. The research and experimentation credits begin to expire
in  2005 for federal purposes and carry forward indefinitely for state purposes.
The Company  has  federal  foreign tax  credit  carryforwards  of  approximately
$25,000  which expire  in 1998.  The utilization of  net operating  loss and tax
credit carryforwards will be subject to  a substantial annual limitation due  to
the  ownership change limitations under the  provisions of Internal Revenue Code
Section 382 and  similar state provisions.  The annual limitation  is likely  to
result  in the expiration  of most of  the Company's net  operating loss and tax
credit carryforwards before full utilization.
 
10. Convertible Redeemable Preferred Stock:
    All  previously  outstanding  Series  A,  B  and  C  Convertible  Redeemable

(Note 3).

10. Convertible Redeemable Preferred Stock: (Continued)
    The holders of new Series A and  new Series A1 preferred stock are  entitled
to  voting rights equal to  the number of shares of  common stock into which the
shares of preferred stock could be converted.
 
    The holders of new Series A and  new Series A1 preferred stock are  entitled
to  noncumulative dividends at an annual rate  of $.33 per share, when declared,
and can convert  their shares, at  any time, into  shares of common  stock at  a
conversion price of $3.66 per share, with adjustments to the conversion price as
defined  in  the Company's  Articles of  Incorporation.  No dividends  have been
declared as of December 31, 1995. The preferred shares automatically convert  to
common  stock on the closing of a  public offering of the Company's common stock
if aggregate gross proceeds exceed $15,000,000 and the per share issuance  price
is  equal to or greater than $7.41. Holders of new Series A preferred stock have
the right of first refusal to purchase a pro rata portion of certain new  equity
securities offered by the Company.
 
    The  new  Series A  and new  Series  A1 preferred  stock have  a liquidation
preference (the "liquidation preference") of  $3.66 per share plus any  declared
and  unpaid dividends.  After the payment  or setting apart  of this liquidation
preference, the holders of new  Series A, new Series  A1 and common stock  shall
receive  pro rata, on an as converted basis, the remaining assets of the Company
until such time  the holders of  new Series A  and new Series  A1 have  received
aggregate  liquidation  distributions  of  $10.98  per  share.  Thereafter,  any
remaining assets will be distributed to the holders of common stock.
 
    A majority of the Series A and Series A1 preferred stockholders may elect  a
mandatory  redemption after December 31, 2002 at $3.66 per share, payable in two
equal annual installments.
 
    SERIES C (RETIRED)
 
    The excess of the redemption value over the carrying value of the old Series
C preferred stock of  $400,000 was being accreted  beginning January 1, 1993  by
annual  charges to retained  earnings of $80,000  using the straight-line method
which  approximated  the  interest  method.  The  1995  accretion  through   the
Recapitalization date was $60,000.
 
11. 1990 Incentive Stock Option Plan:
    The  Company had a 1990 Incentive Stock Option Plan (the "1990 Option Plan")
under which options were granted at the then estimated fair market value of  the
Company's  common stock as determined by the Board of Directors. The 1990 Option
Plan was terminated during the Recapitalization and outstanding options,  except
for  the options to acquire 40,833 shares  of common stock discussed below, were
canceled. Certain of the canceled options  were replaced with new options  under
the 1995 Stock Plan.

an amount  not to  exceed 12%  of  the employee's  contribution. There  were  no
Company contributions in 1993, 1994 or 1995.
 
    MANAGEMENT INCENTIVE BONUS PROGRAMS
 
    During  1995, the Company approved a Management Incentive Bonus Program (the
"Bonus Plan") for directors and officers. The Bonus Plan provides for bonuses of
up to 20% of base  compensation, provided certain specific performance  criteria
are  met. No bonuses  were payable for  1995 unless the  Company achieved 90% or
more of both its 1995 operating  plan revenues and operating profit. No  amounts
were due or paid in 1995 under this 1995 Bonus Plan. A similar bonus plan was in
effect in 1994, and $24,549 was earned under that plan.
 
    During  1995,  the Company  established a  European Sales  Incentive Program
which  provides,  for  eligible  employees  based  in  Europe,  for   additional
compensation  provided specific  performance criteria  are met.  During the year
ended December 31, 1995, $7,748 was earned and paid under this European Program.
 
    EMPLOYMENT AGREEMENTS
 
    The Company has entered  into employment agreements  with its President  and
Chief Executive Officer and Director of European Sales. These agreements provide
for  a minimum annual salary through 1996 and may be terminated by either party.
The agreements also contain severance  provisions which grant the employees  the
right  to  receive  salary  and  benefits,  as  individually  defined,  if  such
employee's employment is terminated by the Company without cause.
 
    DISTRIBUTION AGREEMENT
 
    In 1995, the Company entered into  an agreement whereby another company  was
appointed   as  the  Company's  distributor  for  certain  products  in  certain
territories.   The   agreement   required   nonrefundable   payments   in    the

amount  of $3,500,000 which were  received by the Company  during the year ended
December  31,  1995  and  are   included  in  operations  on  the   accompanying
consolidated  statement of operations  as other operating  income. The agreement
does not have a fixed term.
 
14. Net Loss Per Common Share:
    Net loss per common share is based on reported net loss, with such  reported
net  loss increased for accretion of the Series C preferred stock. The resulting
amount is presented below as loss applicable to common stock.
 
    Such loss applicable to common stock in each period presented is divided  by
the  weighted  average number  of outstanding  common  shares which,  along with
shares issuable under other equity securities, have been computed in  accordance
with  Securities and Exchange Commission Staff Accounting Bulletin ("SAB") Topic
4-D. The SAB  requires that common  stock issued  by the Company  in the  twelve
months  immediately  preceding a  proposed public  offering  plus the  number of
common equivalent shares which become  issuable during the same period  pursuant
to  the  issuance of  warrants or  grant  of stock  options (using  the modified
treasury stock method), and issuance  of convertible preferred stock, at  prices
less  than  the per  share  initial public  offering  price be  included  in the
calculation of common stock and common  stock equivalent shares as if they  were
outstanding for all periods presented.

15. Pro Forma Financial Statement Information:
    Upon  the closing of the Company's initial public offering, each outstanding
share of the Company's preferred stock will be converted automatically to common
stock. The pro forma effect of the  conversion has been presented as a  separate
column  in the Company's consolidated balance  sheet assuming the conversion had
occurred as of March 31, 1996.
 
    Shares used in  computing net loss  per share are  the same as  for the  pro
forma  net loss per share calculation  since all convertible preferred stock was
included in the shares used for historical net loss per share in accordance with
SAB Topic 4-D.

16. Credit Risk:
    The Company maintains cash deposits at a  bank. As of December 31, 1994  and
1995,  the Company had cash on deposit of $89,696 and $270,316, respectively, in
excess of the federally-insured limit.
 
    The Company's customers are primarily physicians and hospitals in the United
States  and   certain  foreign   countries,  and   domestic  and   international
distributors.  The two largest customers accounted for approximately 40% and 56%
of accounts receivable at December 31, 1994 and 1995, respectively. One customer
accounted for approximately 75%  of accounts receivable at  March 31, 1996.  The
two  largest customers totaled approximately 38% and  25% of sales for the years
ended December 31, 1993 and 1994, respectively, and the three largest  customers
totaled  approximately 43% of  sales for the  year ended December  31, 1995. One
customer totaled approximately 89% of sales for the three months ended March 31,
1996.
 
    The Company reviews a customer's credit history before extending credit  and
may require an international customer to provide an irrevocable letter of credit
drawn  on a  bank previously  approved by  the Company.  The Company establishes
allowances for doubtful accounts based upon factors surrounding the credit  risk
of  specific customers. The accounting loss, should a customer be unable to meet
its  obligation  to  the  Company,  would  be  equal  to  the  recorded  account
receivable.
 
17. Segment Information:
    The Company's products are sold in the following geographic regions:

18. Subsequent Events:
    On  April  8,  1996  the  Board of  Directors  authorized  the  filing  of a
registration statement with  the Securities and  Exchange Commission  permitting
the Company to sell shares of its common stock to the public. If the offering is
consummated  under terms presently anticipated, all of the currently outstanding
preferred stock will automatically convert to 2,715,546 shares of common stock.
 
    In  conjunction  with  this  registration,   the  Board  of  Directors   and
stockholders  approved a  1 for  1.4814 reverse  stock split  of all outstanding
common stock, preferred stock and common stock options. All share and per  share
amounts have been adjusted to give retroactive effect to the reverse stock split
for all periods presented.
 
    In  April 1996 the Board of Directors  adopted the 1996 Director Option Plan
and the  1996 Employee  Stock Purchase  Plan and  reserved 200,000  and  200,000
shares  of common stock, respectively, for issuance thereunder. The Company also
authorized 50,000,000  shares of  $0.001 par  value common  stock and  5,000,000
shares of $0.001 par value preferred stock.
 
    From  January through April 1, 1996,  the Company granted 120,160 options to
purchase common stock pursuant  to the 1995 Stock  Plan at exercise prices  from
$0.222  to $8.888  per share and  approved an  increase in the  number of shares
reserved under the 1995 Stock Plan to 1,675,000.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law permits a corporation to
include  in its charter documents, and in agreements between the corporation and
its directors and  officers, provisions expanding  the scope of  indemnification
beyond that specifically provided by the current law.
 
    Article  VIII of the Registrant's  Certificate of Incorporation provides for
the indemnification  of  directors  to  the  fullest  extent  permissible  under
Delaware law.
 
    Article  VI of the  Registrant's Bylaws provides  for the indemnification of
officers, directors and  third parties acting  on behalf of  the corporation  if
such person acted in good faith and in a manner reasonably believed to be in and
not  opposed to the best  interest of the corporation,  and, with respect to any
criminal action or proceeding,  the indemnified party had  no reason to  believe
his conduct was unlawful.
 
    The   Registrant  has  entered  into  indemnification  agreements  with  its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws,  and intends to  enter into indemnification  agreements
with any new directors and executive officers in the future.
 
    The  Underwriting  Agreement  filed  as  Exhibit  1.1  to  this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the  Securities
Act, or otherwise.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    Between  May 1993 and  April 1995 Registrant issued  24,240 shares of Common
Stock to a  total of eleven  employees and consultants  pursuant to exercise  of
options to purchase Common Stock for an aggregate purchase price of $48,693 with
a weighted average exercise price of approximately $2.01 per share.
 
    In  September 1994, Registrant issued 335 shares of Series C Preferred Stock
to one venture capital investor at a price of $36.63 per share for an  aggregate
purchase price of $12,239.
 
    In  October  1994, Registrant  issued 45,903  shares  to Franklin  D. Brown,
President, Chief Executive Officer and Chairman of the Board of Registrant, at a
price of $3.70 per share for an aggregate purchase price of $170,000, which  was
paid  with a  promissory note.  Such shares were  repurchased by  the Company in
August 1995 for the same consideration exchanged by Mr. Brown to purchase them.
 
    In April  1995,  Registrant  issued  338  shares  of  Common  Stock  to  two
consultants  to  Registrant at  a  price of  $3.70  per share  for  an aggregate
purchase price of $1,250.
 
                                      II-1
<PAGE>
    From  May  to  August  1995,  Registrant  issued  281,034  warrants  for  no
additional  consideration to a total of seven venture capital, institutional and
individual investors  in  connection  with Registrant's  bridge  loan  financing
issuance of $2,056,586 of subordinated promissory notes, convertible into shares
of New Series A Preferred Stock, at 9% interest.
 
    In  September  1995,  Registrant  sold  2,715,546  shares  of  New  Series A
Preferred Stock  to  a  total  of  twelve  venture  capital,  institutional  and
individual  investors at  a price  of $3.66 per  share, which  sale included the
conversion of  the  subordinated  promissory notes  described  in  the  previous
paragraph.  The aggregate  purchase price  consisted of  $7,879,691 in  cash and
$2,056,587  of  subordinated  promissory  notes.   Pursuant  to  such  sale,   a
recapitalization  of Registrant was performed to  convert all of the outstanding
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred  Stock
into  Common Stock  and the  warrants described  in the  previous paragraph were
exchanged for 281,034 shares of Common Stock for no additional consideration. In
contemplation of such recapitalization, a  one-for-five reverse stock split  was
effected in August 1995.
 
    In October 1995, Registrant sold 328,069 shares of Common Stock to Mr. Brown
at a purchase price of $0.22 per share pursuant to a stock purchase agreement. A
separate  agreement  dated  April  1996  provided  Registrant  with  a  right to
repurchase such shares, at a price of $0.22 per share for an aggregate  purchase
price  of $72,900. Such shares are subject  to a repurchase option which expires
with respect to  35% of  the shares  in September 1996  and the  remainder on  a
monthly pro rata basis through September 1998.
 
    In  March  1996, Registrant  issued 40,833  shares of  Common Stock  to Glen
French, a former  director and officer  of Registrant  at a price  of $1.11  per
share for an aggregate purchase price of $46,368 pursuant to exercise of options
under the 1990 Option Plan.
 
    The sales of the above securities were deemed to be exempt from registration
under  the  Securities Act  of  1933 in  reliance  on section  4(2)  thereof, or
Regulation D promulgated thereunder, or Rule 701 promulgated under Section  3(b)
thereof,  as  transactions  by an  issuer  not  involving a  public  offering or
transactions pursuant to  compensatory benefit plans  and contracts relating  to
compensation  as provided under  Rule 701. The recipients  of securities in each
such transaction  represented  their intention  to  acquire the  securities  for
investment  only and  not with  a view  to or  for sale  in connection  with any
distribution thereof and appropriate legends were affixed the share certificates
and instruments issued in such transactions. All recipients had adequate access,
through  their  relationships  with  the   Company  to  information  about   the
Registrant.

    (B) FINANCIAL STATEMENT SCHEDULES
 
    Schedules  not  listed  above  have  been  omitted  because  the information
required to be set forth therein is not applicable or is shown in the  financial
statements or notes thereto.
 
ITEM 17.  UNDERTAKINGS
 
    The  undersigned Registrant hereby undertakes to provide to the Underwriters
at the  closing specified  in the  Underwriting Agreement  certificates in  such
denominations  and registered in  such names as required  by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification by the  Registrant for liabilities arising  under
the  Securities  Act  of  1933  may  be  permitted  to  directors,  officers and
controlling persons of the Registrant  pursuant to the provisions referenced  in
Item  14 of this  Registration Statement, or otherwise,  the Registrant has been
advised that  in the  opinion of  the Securities  and Exchange  Commission  such
indemnification is against public policy as
 
                                      II-3
<PAGE>
expressed  in the Securities Act, and is, therefore, unenforceable. In the event
that a  claim  for indemnification  against  such liabilities  (other  than  the
payment  by the Registrant of expenses incurred  or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling  person
in  connection with  the securities  being registered  hereunder, the Registrant
will, unless  in the  opinion of  its counsel  the matter  has been  settled  by
controlling  precedent,  submit  to  a  court  of  appropriate  jurisdiction the
question whether  such  indemnification  by  it  is  against  public  policy  as
expressed  in the Securities Act and will  be governed by the final adjudication
of such issue.
 
    The undersigned Registrant hereby further undertakes that:
 
        (1) For purposes of determining  any liability under the Securities  Act
    of  1933, the information omitted from the  form of Prospectus filed as part
    of this Registration Statement in reliance upon Rule 430A and contained in a
    form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h)  under the  Securities Act  shall be  deemed to  be part  of  this
    Registration Statement as of the time it was declared effective.
 
        (2)  For the purpose  of determining any  liability under the Securities
    Act  of  1933,  each  post-effective  amendment  that  contains  a  form  of
    Prospectus  shall be deemed  to be a new  registration statement relating to
    the securities offered therein, and the offering of such securities at  that
    time shall be deemed to be the initial bona fide offering thereof.

                                   SIGNATURES
 
    Pursuant  to the requirements of the Securities Act, the Registrant has duly
caused this Amendment  to Registration Statement  333-3542 to be  signed on  its
behalf  by the  undersigned, thereunto  duly authorized,  in the  City of Laguna
Niguel, State of California, on the 15th day of May, 1996.

     THIS AGREEMENT AND PLAN OF MERGER dated as of May  , 1996, (the 
"Agreement") is between Imagyn Medical, Inc., a Delaware corporation 
("Imagyn-Delaware") and Imagyn Medical, Inc., a California corporation 
("Imagyn-California").  Imagyn-Delaware and Imagyn-California are sometimes

     3.3  IMAGYN-CALIFORNIA OPTIONS, STOCK PURCHASE RIGHTS AND CONVERTIBLE 
          SECURITIES.

          (a)  Upon the Effective Date of the Merger, the Surviving 
Corporation shall assume the obligations of Imagyn-California under, and 
continue, the option plans (including without limitation the 1995 Stock Plan, 
1996 Employee Stock Purchase Plan and 1996 Director Option Plan) and all 
other employee benefit plans of Imagyn-California.  Each outstanding and 
unexercised option, other right to purchase, or security convertible into, 
Imagyn-California Common Stock or Imagyn-California Preferred Stock (a 
"Right") shall become, subject to the provisions in paragraph (c) hereof, an 
option, right to purchase or a security convertible into the Surviving 
Corporation's Common Stock or Preferred Stock, respectively, on the basis of 
one share of the Surviving Corporation's Common Stock or Preferred Stock, as 
the case may be, for each one share of Imagyn-California Common Stock or 
Preferred Stock, as the case may be, issuable pursuant to any such Right, on 
the same terms and conditions and at an exercise price equal to the exercise 
price applicable to any such Imagyn-California Right at the Effective Date of 
the Merger.  This paragraph 3.3(a) shall not apply to Imagyn-California 
Common Stock or Preferred Stock.  Such Common Stock and Preferred Stock are 
subject to paragraph 3.1 and 3.2, respectively, hereof.

          (b)  A number of shares of the Surviving Corporation's Common Stock 
and Preferred Stock shall be reserved for issuance upon the exercise of 
options, stock purchase rights and convertible securities equal to the number 
of shares of Imagyn-California Common Stock and Imagyn-California Preferred 
Stock so reserved immediately prior to the Effective Date of the Merger.

          (c)  The assumed Rights shall not entitle any holder thereof to a 
fractional share upon exercise or conversion (unless the holder was entitled 
to a fractional interest immediately prior to the Merger).  In lieu thereof, 
any fractional share interests to which a holder of an assumed Right (other 
than an option issued pursuant to Imagyn-Delaware's 1995 Stock Plan, 1996 
Employee Stock Purchase Plan and 1996 Director Option Plan) would otherwise 
be entitled upon exercise or conversion shall be aggregated (but only with 
other similar Rights which have the same per share terms).  To the extent 
that after such aggregation, the holder would still be entitled to a 
fractional share with respect thereto upon exercise or conversion, the holder 
shall be entitled upon the exercise or conversion of all such assumed Rights 
pursuant to their terms (as modified herein), to one full share of Common 
Stock or Preferred Stock in lieu of such fractional share.  With respect to 
each class of such similar Rights, no holder will be entitled to more than 
one full share in lieu of a fractional share upon exercise or conversion.

     Notwithstanding the foregoing, with respect to options issued under the 
Imagyn-California 1995 Stock Plan, 1996 Employee Stock Purchase Plan and 1996 
Director Option Plan that are assumed in the Merger, the number of shares of 
Common Stock to which the holder would be otherwise entitled upon exercise of 
each such assumed option following the Merger shall be rounded down to the 
nearest whole number and the exercise price shall be rounded up to the 
nearest whole cent.  In addition, no "additional benefits" (within the 
meaning of Section 424(a)(2)


                                     -4-

<PAGE>


of the Internal Revenue Code of 1986, as amended) shall be accorded to the 
optionees pursuant to the assumption of their options.

     3.4  IMAGYN-DELAWARE COMMON STOCK.  Upon the Effective Date of the 
Merger, each share of Common Stock, $.001 par value, of Imagyn-Delaware 
issued and outstanding immediately prior thereto shall, by virtue of the 
Merger and without any action by Imagyn-Delaware, the holder of such shares 
or any other person, be canceled and returned to the status of authorized but 
unissued shares.

     3.5  EXCHANGE OF CERTIFICATES.  After the Effective Date of the Merger, 
each holder of an outstanding certificate representing shares of 
Imagyn-California Common Stock or Preferred Stock may be asked to surrender 
the same for cancellation to an exchange agent, whose name will be delivered 
to holders prior to any requested exchange (the "Exchange Agent"), and each 
such holder shall be entitled to receive in exchange therefor a certificate 
or certificates representing the number of shares of the Surviving 
Corporation's Common Stock or Preferred Stock, as the case may be, into which 
the surrendered shares were converted as herein provided.  Until so 
surrendered, each outstanding certificate theretofore representing shares of 
Imagyn-California Common Stock or Preferred Stock shall be deemed for all 
purposes to represent the number of shares of the Surviving Corporation's 
Common Stock or Preferred Stock, respectively, into which such shares of 
Imagyn-California Common Stock or Preferred Stock, as the case may be, were 
converted in the Merger.

     The registered owner on the books and records of the Surviving 
Corporation or the Exchange Agent of any such outstanding certificate shall, 
until such certificate shall have been surrendered for transfer or conversion 
or otherwise accounted for to the Surviving Corporation or the Exchange 
Agent, have and be entitled to exercise any voting and other rights with 
respect to and to receive dividends and other distributions upon the shares 
of Common Stock or Preferred Stock of the Surviving Corporation represented 
by such outstanding certificate as provided above.

     Each certificate representing Common Stock or Preferred Stock of the 
Surviving Corporation so issued in the Merger shall bear the same legends, if 
any, with respect to the restrictions on transferability as the certificates 
of Imagyn-California so converted and given in exchange therefore, unless 
otherwise determined by the Board of Directors of the Surviving Corporation 
in compliance with applicable laws.

     If any certificate for shares of the Surviving Corporation's stock is to 
be issued in a name other than that in which the certificate surrendered in 
exchange therefor is registered, it shall be a condition of issuance thereof 
that the certificate so surrendered shall be properly endorsed and otherwise 
in proper form for transfer, that such transfer otherwise be proper and 
comply with applicable securities laws and that the person requesting such 
transfer pay to the Exchange Agent any transfer or other taxes payable by 
reason of issuance of such new certificate in a name other than that of the 
registered holder of the certificate surrendered or establish to the 
satisfaction of the Surviving Corporation that such tax has been paid or is 
not payable.

directors of Imagyn-Delaware are fully authorized in the name and on behalf

     4.3  ABANDONMENT.  At any time before the Effective Date of the Merger,

                             ARTICLE III

     The purpose of the corporation is to engage in any lawful act or

Corporation Law of Delaware.

                             ARTICLE IV

     The corporation is authorized to issue two classes of shares of stock to 
be designated, respectively, Common Stock, $0.001 par value, and Preferred 
Stock, $0.001 par value.  The total number of shares that the corporation is 
authorized to issue is 55,000,000 shares.  The number of shares of Common

<PAGE>


     The Preferred Stock may be issued from time to time in one or more 
series pursuant to a resolution or resolutions providing for such issue duly 
adopted by the board of directors (authority to do so being hereby expressly 
vested in the board).  The board of directors is further authorized to 
determine or alter the rights, preferences, privileges and restrictions 
granted to or imposed upon any wholly unissued series of Preferred Stock and 
to fix the number of shares of any series of Preferred Stock and the 
designation of any such series of Preferred Stock.  The board of directors, 
within the limits and restrictions stated in any resolution or resolutions of 
the board of directors originally fixing the number of shares constituting 
any series, may increase or decrease (but not below the number of shares in 
any such series then outstanding) the number of shares of any series 
subsequent to the issue of shares of that series.

     The authority of the board of directors with respect to each such class 
or series shall include, without limitation of the foregoing, the right to 
determine and fix:

               (a)  the distinctive designation of such class or series and 
the number of shares to constitute such class or series;

               (b)  the rate at which dividends on the shares of such class 
or series shall be declared and paid, or set aside for payment, whether 
dividends at the rate so determined shall be cumulative or accruing, and 
whether the shares of such class or series shall be entitled to any 
participating or other dividends in addition to dividends at the rate so 
determined, and if so, on what terms;

               (c)  the right or obligation, if any, of the corporation to 
redeem shares of the particular class or series of Preferred Stock and, if 
redeemable, the price, terms and manner of such redemption;

               (d)  the special and relative rights and preferences, if any, 
and the amount or amounts per share, which the shares of such class or series 
of Preferred Stock shall be entitled to receive upon any voluntary or 
involuntary liquidation, dissolution or winding up of the corporation;

               (e)  the terms and conditions, if any, upon which shares of 
such class or series shall be convertible into, or exchangeable for, shares 
of capital stock of any other class or series, including the price or prices 
or the rate or rates of conversion or exchange and the terms of adjustment, 
if any;

               (f)  the obligation, if any, of the corporation to retire, 
redeem or purchase shares of such class or series pursuant to a sinking fund 
or fund of a similar nature or otherwise, and the terms and conditions of 
such obligation;

               (g)  voting rights, if any, on the issuance of additional 
shares of such class or series or any shares of any other class or series of 
Preferred Stock;

               (h)  limitations, if any, on the issuance of additional shares 
of such class or series or any shares of any other class or series of 
Preferred Stock; and

               (i)  such other preferences, powers, qualifications, special 
or relative rights and privileges thereof as the board of directors of the 
corporation, acting in accordance with this Restated Certificate of 
Incorporation, may deem advisable and are not inconsistent with law and the 
provisions of this Restated Certificate of Incorporation.

                              ARTICLE V

     The corporation reserves the right to amend, alter, change, or repeal 
any provision contained in this Certificate of Incorporation, in the manner 
now or hereafter prescribed by statute, and all rights conferred upon the 
stockholders herein are granted subject to this right.

                             ARTICLE VI

     The corporation is to have perpetual existence.

                             ARTICLE VII

     1.   LIMITATION OF LIABILITY.  To the fullest extent permitted by the 
General Corporation Law of the State of Delaware as the same exists or as may 
hereafter be amended, a director of the corporation shall not be personally 
liable to the corporation or its stockholders for monetary damages for breach 
of fiduciary duty as a director.

     2.   INDEMNIFICATION.  The corporation may indemnify to the fullest 
extent permitted by law any person made or threatened to be made a party to 
an action or proceeding, whether criminal, civil, administrative or 
investigative, by reason of the fact that such person or his or her testator 
or intestate is or was a director, officer or employee of the corporation, or 
any predecessor of the corporation, or serves or served at any other 
enterprise as a director, officer or employee at the request of the 
corporation or any predecessor to the corporation.

     3.   AMENDMENTS.  Neither any amendment nor repeal of this Article VII, 
nor the adoption of any provision of the corporation's Certificate of 
Incorporation inconsistent with this Article VII, shall eliminate or reduce 
the effect of this Article VII, in respect of any matter occurring, or any 
action or proceeding accruing or arising or that, but for this Article VII, 
would accrue or arise, prior to such amendment, repeal, or adoption of an 
inconsistent provision.

                            ARTICLE VIII

     In the event any shares of Preferred Stock shall be redeemed or 
converted pursuant to the terms hereof, the shares so converted or redeemed 
shall not revert to the status of authorized but unissued shares, but instead 
shall be canceled and shall not be re-issuable by the corporation.

                             ARTICLE IX

     Holders of stock of any class or series of the corporation shall not be 
entitled to cumulate their votes for the election of directors or any other 
matter submitted to a vote of the stockholders, unless such cumulative voting 
is required pursuant to Sections 2115 and/or 301.5 of the California General 
Corporation Law, in which event each such holder shall be entitled to as many 
votes as shall equal the number of votes which (except for this provision as 
to cumulative voting) such holder would be entitled to cast for the election 
of directors with respect to his shares of stock multiplied by the number of 
directors to be elected by him, and the holder may cast all of such votes for 
a single director or may distribute them among the number of directors to be 
voted for, or for any two or more of them as such holder may see fit, so long 
as the name of the candidate for director shall have been placed in 
nomination prior to the voting and the stockholder, or any other holder of 
the same class or series of stock, has given notice at the meeting prior to 
the voting of the intention to cumulate votes.

                              ARTICLE X

    2.2  ANNUAL MEETING

    The annual meeting of stockholders shall be held each year on a date and at

the board of directors may be held.

accordance with Section 2.6 of these bylaws not less than ten (10) nor more 
than sixty (60) days before the date of the meeting.  The notice shall specify 
the place, date and hour of the meeting and (i) in the case of a special 
meeting, the purpose or purposes for which the meeting is called (no business

    (a)  nominations for the election of directors, and

    (b)  business proposed to be brought before any stockholder meeting 


                                      -2-

<PAGE>

may be made by the board of directors or proxy committee appointed by the board 
of directors or by any stockholder entitled to vote in the election of 
directors generally if such nomination or business proposed is otherwise proper 
business before such meeting.  However, any such stockholder may nominate one 
or more persons for election as directors at a meeting or propose business to 
be brought before a meeting, or both, only if such stockholder has given timely 
notice in proper written form of their intent to make such nomination or 
nominations or to propose such business.  To be timely, such stockholder's 
notice must be delivered to or mailed and received at the principal executive 
offices of the corporation not less than one hundred twenty (120) calendar days 
in advance of the date specified in the corporation's proxy statement released 
to stockholders in connection with the previous year's annual meeting of 
stockholders; provided, however, that in the event that no annual meeting was 
held in the previous year or the date of the annual meeting has been changed by 
more than thirty (30) days from the date contemplated at the time of the 
previous year's proxy statement, notice by the stockholder to be timely must be 
so received a reasonable time before the solicitation is made.  To be in proper 
form, a stockholder's notice to the secretary shall set forth:

    (i)  the name and address of the stockholder who intends to make the 
    nominations or propose the business and, as the case may be, of the person 
    or persons to be nominated or of the business to be proposed;

    (ii) a representation that the stockholder is a holder of record of stock 
    of the corporation entitled to vote at such meeting and, if applicable, 
    intends to appear in person or by proxy at the meeting to nominate the 
    person or persons specified in the notice;
    
    (iii)  if applicable, a description of all arrangements or understandings 
    between the stockholder and each nominee and any other person or persons 
    (naming such person or persons) pursuant to which the nomination or 
    nominations are to be made by the stockholder;
    
    (iv) such other information regarding each nominee or each matter of 
    business to be proposed by such stockholder as would be required to be 
    included in a proxy statement filed pursuant to the proxy rules of the 
    Securities and Exchange Commission had the nominee been nominated, or 
    intended to be nominated, or the matter been proposed, or intended to be 
    proposed by the board of directors; and
    
    (v)  if applicable, the consent of each nominee to serve as director of 
    the corporation if so elected.

    The chairman of the meeting shall refuse to acknowledge the nomination of 
any person or the proposal of any business not made in compliance with the 
foregoing procedure.

    2.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

    Written notice of any meeting of stockholders shall be given either 
personally or by first-class mail or by telegraphic or other written 
communication.  Notices not personally delivered shall be sent charges prepaid 
and shall be addressed to the stockholder at the address of that stockholder 
appearing on the books of the corporation or given by the stockholder to the 
corporation for the purpose of notice. Notice shall be deemed to have been 
given at the time when delivered personally or deposited in the mail or sent by 
telegram or other means of written communication.

    An affidavit of the mailing or other means of giving any notice of any 
stockholders' meeting, executed by the secretary, assistant secretary or any 
transfer agent of the corporation giving the notice, shall be prima facie 
evidence of the giving of such notice.

    2.7  QUORUM

    The holders of a majority in voting power of the stock issued and 
outstanding and entitled to vote thereat, present in person or represented by 
proxy, shall constitute a quorum at all meetings of the stockholders for the 
transaction of business except as otherwise provided by statute or by the 
certificate of incorporation.  If, however, such quorum is not present or 
represented at any meeting of the stockholders, then either (i) the chairman of 
the meeting or (ii) the stockholders entitled to vote thereat, present in 
person or represented by proxy, shall have power to adjourn the meeting in 
accordance with Section 2.7 of these bylaws.

    When a quorum is present at any meeting, the vote of the holders of a 
majority of the stock having voting power present in person or represented by 
proxy shall decide any question brought before such meeting, unless the 
question is one upon which, by express provision of the laws of the State of 
Delaware or of the certificate of incorporation or these bylaws, a different 
vote is required, in which case such express provision shall govern and control 
the decision of the question.

    If a quorum be initially present, the stockholders may continue to transact 
business until adjournment, notwithstanding the withdrawal of enough 
stockholders to leave less than a quorum, if any action taken is approved by a 
majority of the stockholders initially constituting the quorum.

    2.8  ADJOURNED MEETING; NOTICE

    When a meeting is adjourned to another time and place, unless these bylaws 
otherwise require, notice need not be given of the adjourned meeting if the 
time and place thereof are announced at the meeting at which the adjournment is 
taken.  At the adjourned meeting the corporation may transact any business that 
might have been transacted at the original meeting.  If the adjournment is for 
more than thirty (30) days, or if after the adjournment a new record date is 
fixed for the adjourned meeting, a notice of the adjourned meeting shall be 
given to each stockholder of record entitled to vote at the meeting.


                                      -4-

    2.9  VOTING

    The stockholders entitled to vote at any meeting of stockholders shall be 
determined in accordance with the provisions of Section 2.11 of these bylaws, 
subject to the provisions of Sections 217 and 218 of the General Corporation 
Law of Delaware (relating to voting rights of fiduciaries, pledgors and joint 
owners, and to voting trusts and other voting agreements).

    Except as may be otherwise provided in the certificate of incorporation or 
these bylaws, each stockholder shall be entitled to one vote for each share of 
capital stock held by such stockholder and stockholders shall not be entitled 
to cumulate their votes in the election of directors or with respect to any 
matter submitted to a vote of the stockholders.  

    Notwithstanding the foregoing, if the stockholders of the corporation are 
entitled, pursuant to Sections 2115 and 301.5 of the California Corporations 
Code, to cumulate their votes in the election of directors, each such 
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a 
number of votes greater than the number of votes that such stockholder normally 
is entitled to cast) only if the candidates' names have been properly placed in 
nomination (in accordance with these bylaws) prior to commencement of the 
voting, and the stockholder requesting cumulative voting has given notice prior 
to commencement of the voting of the stockholder's intention to cumulate votes. 
 If cumulative voting is properly requested, each holder of stock, or of any 
class or classes or of a series or series thereof, who elects to cumulate votes 
shall be entitled to as many votes as equals the number of votes that (absent 
this provision as to cumulative voting) he or she would be entitled to cast for 
the election of directors with respect to his or her shares of stock multiplied 
by the number of directors to be elected by him, and he or she may cast all of 
such votes for a single director or may distribute them among the number to be 
voted for, or for any two or more of them, as he or she may see fit.

    2.10 STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Unless otherwise provided in the certificate of incorporation, any action 
required or permitted to be taken at any annual or special meeting of 
stockholders may be taken without a meeting, without prior notice and without a 
vote, if a consent or consents in writing, setting forth the action so taken, 
shall be signed by the holders of outstanding stock having not less than the 
minimum number of votes that would be necessary to authorize or take such 
action at a meeting at which all shares entitled to vote thereon were present 
and voted.  Such consents shall be delivered to the corporation by delivery to 
its registered office in the state of Delaware, its principal place of 
business, or an officer or agent of the corporation having custody of the book 
in which proceedings of meetings of stockholders are recorded. Delivery made to 
the corporation's registered office shall be by hand or by certified or 
registered mail, return receipt requested.

    2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING

    For purposes of determining the stockholders entitled to notice of any 
meeting or to vote thereat, the board of directors may fix, in advance, a 
record date, which shall not precede the date upon which 


                                      -5-

<PAGE>

the resolution fixing the record date is adopted by the board of directors and 
which shall not be more than sixty (60) days nor less than ten (10) days before 
the date of any such meeting, and in such event only stockholders of record on 
the date so fixed are entitled to notice and to vote, notwithstanding any 
transfer of any shares on the books of the corporation after the record date.

    If the board of directors does not so fix a record date, the record date 
for determining stockholders entitled to notice of or to vote at a meeting of 
stockholders shall be at the close of business on the business day next 
preceding the day on which notice is given, or, if notice is waived, at the 
close of business on the business day next preceding the day on which the 
meeting is held.

    A determination of stockholders of record entitled to notice of or to vote 
at a meeting of stockholders shall apply to any adjournment of the meeting 
unless the board of directors fixes a new record date for the adjourned 
meeting, but the board of directors shall fix a new record date if the meeting 
is adjourned for more than thirty (30) days from the date set for the original 
meeting.

    The record date for any other purpose shall be as provided in Section 8.1 
of these bylaws.

    2.12 PROXIES

    Every person entitled to vote for directors, or on any other matter, shall 
have the right to do so either in person or by one or more agents authorized by 
a written proxy signed by the person and filed with the secretary of the 
corporation, but no such proxy shall be voted or acted upon after three (3) 
years from its date, unless the proxy provides for a longer period.  A proxy 
shall be deemed signed if the stockholder's name is placed on the proxy 
(whether by manual signature, typewriting, telegraphic transmission, telecopy 
or otherwise) by the stockholder or the stockholder's attorney-in-fact.  The 
revocability of a proxy that states on its face that it is irrevocable shall be 
governed by the provisions of Section 212(e) of the General Corporation Law of 
Delaware.

    2.13 ORGANIZATION

    The president, or in the absence of the president, the chairman of the 
board, or, in the absence of the president and the chairman of the board, one 
of the corporation's vice presidents, shall call the meeting of the 
stockholders to order, and shall act as chairman of the meeting.  In the 
absence of the president, the chairman of the board, and all of the vice 
presidents, the stockholders shall appoint a chairman for such meeting.  The 
chairman of any meeting of stockholders shall determine the order of business 
and the procedures at the meeting, including such matters as the regulation of 
the manner of voting and the conduct of business.  The secretary of the 
corporation shall act as secretary of all meetings of the stockholders, but in 
the absence of the secretary at any meeting of the stockholders, the chairman 
of the meeting may appoint any person to act as secretary of the meeting.

    2.14 LIST OF STOCKHOLDERS ENTITLED TO VOTE

    The officer who has charge of the stock ledger of the corporation shall 
prepare and make, at least ten (10) days before every meeting of stockholders, 
a complete list of the stockholders entitled to vote at the meeting, arranged 
in alphabetical order, and showing the address of each stockholder and the 
number of shares registered in the name of each stockholder.  Such list shall 
be open to the examination of any stockholder, for any purpose germane to the 
meeting, during ordinary business hours, for a period of at least ten (10) days 
prior to the meeting, either at a place within the city where the meeting is to 
be held, which place shall be specified in the notice of the meeting, or, if 
not so specified, at the place where the meeting is to be held.  The list shall 
also be produced and kept at the time and place of the meeting during the whole 
time thereof, and may be inspected by any stockholder who is present.

    2.15 WAIVER OF NOTICE

    Whenever notice is required to be given under any provision of the General 
Corporation Law of Delaware or of the certificate of incorporation or these 
bylaws, a written waiver thereof, signed by the person entitled to notice, 
whether before or after the time stated therein, shall be deemed equivalent to 
notice.  Attendance of a person at a meeting shall constitute a waiver of 
notice of such meeting, except when the person attends a meeting for the 
express purpose of objecting, at the beginning of the meeting, to the 
transaction of any business because the meeting is not lawfully called or 
convened. Neither the business to be transacted at, nor the purpose of, any 
regular or special meeting of the stockholders need be specified in any written 
waiver of notice unless so required by the certificate of incorporation or 
these bylaws.

                             ARTICLE III

                              DIRECTORS

    3.1  POWERS

    Subject to the provisions of the General Corporation Law of Delaware and to 
any limitations in the certificate of incorporation or these bylaws relating to 
action required to be approved by the stockholders or by the outstanding 
shares, the business and affairs of the corporation shall be managed and all 
corporate powers shall be exercised by or under the direction of the board of 
directors.

    3.2  NUMBER OF DIRECTORS

    The board of directors shall consist of five (5) members.  The number of 
directors may be changed by an amendment to this bylaw, duly adopted by the 
board of directors or by the stockholders, or by a duly adopted amendment to 
the certificate of incorporation.  Upon the closing of the first sale of the 
corporation's common stock pursuant to a firmly underwritten registered public 
offering (the "IPO"), the directors shall be divided into three classes, with 
the term of office of the first class, which class shall 


                                      -7-

<PAGE>

initially consist of one director, to expire at the first annual meeting of 
stockholders held after the IPO; the term of office of the second class, which 
class shall initially consist of two directors, to expire at the second annual 
meeting of stockholders held after the IPO; the  term of office of the third 
class, which class shall initially consist of two directors, to expire at the 
third annual meeting of stockholders held after the IPO; and thereafter for 
each such term to expire at each third succeeding annual meeting of 
stockholders held after such election.

    3.3  ELECTION AND TERM OF OFFICE OF DIRECTORS

    Except as provided in Section 3.4 of these bylaws, directors shall be 
elected at each annual meeting of stockholders to hold office as provided in 
Section 3.2 of these bylaws.  Each director, including a director elected or 
appointed to fill a vacancy, shall hold office until the expiration of the term 
for which elected and until a successor has been elected and qualified.

    3.4  RESIGNATION AND VACANCIES

    Any director may resign effective on giving written notice to the chairman 
of the board, the president, the secretary or the board of directors, unless 
the notice specifies a later time for that resignation to become effective.  If 
the resignation of a director is effective at a future time, the board of 
directors may elect a successor to take office when the resignation becomes 
effective.

    Vacancies in the board of directors may be filled by a majority of the 
remaining directors, even if less than a quorum, or by a sole remaining 
director; however, a vacancy created by the removal of a director by the vote 
of the stockholders or by court order may be filled only by the affirmative 
vote of a majority of the shares represented and voting at a duly held meeting 
at which a quorum is present (which shares voting affirmatively also constitute 
a majority of the required quorum).  Each director so elected shall hold office 
for a term expiring at the next annual meeting of the stockholders at which the 
term of office of the class to which such director has been elected expires.

    Unless otherwise provided in the certificate of incorporation or these 
bylaws:

                   (i)   Vacancies and newly created directorships resulting 
from any increase in the authorized number of directors elected by all of the 
stockholders having the right to vote as a single class may be filled by a 
majority of the directors then in office, although less than a quorum, or by a 
sole remaining director.

                  (ii)   Whenever the holders of any class or classes of stock 
or series thereof are entitled to elect one or more directors by the provisions 
of the certificate of incorporation, vacancies and newly created directorships 
of such class or classes or series may be filled by a majority of the directors 
elected by such class or classes or series thereof then in office, or by a sole 
remaining director so elected.

     If at any time, by reason of death or resignation or other cause, the 
corporation should have no directors in office, then any officer or any 
stockholder or an executor, administrator, trustee or guardian 


                                      -8-

<PAGE>

of a stockholder, or other fiduciary entrusted with like responsibility for the 
person or estate of a stockholder, may call a special meeting of stockholders 
in accordance with the provisions of the certificate of incorporation or these 
bylaws, or may apply to the Court of Chancery for a decree summarily ordering 
an election as provided in Section 211 of the General Corporation Law of 
Delaware.

     If, at the time of filling any vacancy or any newly created directorship, 
the directors then in office constitute less than a majority of the whole board 
(as constituted immediately prior to any such increase), then the Court of 
Chancery may, upon application of any stockholder or stockholders holding at 
least ten (10) percent of the total number of the shares at the time 
outstanding having the right to vote for such directors, summarily order an 
election to be held to fill any such vacancies or newly created directorships, 
or to replace the directors chosen by the directors then in office as 
aforesaid, which election shall be governed by the provisions of Section 211 of 
the General Corporation Law of Delaware as far as applicable.

     3.5  REMOVAL OF DIRECTORS

     Unless otherwise restricted by statute, by the certificate of 
incorporation or by these bylaws, any director or the entire board of directors 
may be removed, with or without cause, by the holders of a majority of the 
shares then entitled to vote at an election of directors; provided, however, 
that, if and so long as stockholders of the corporation are entitled to 
cumulative voting, if less than the entire board is to be removed, no director 
may be removed without cause if the votes cast against his removal would be 
sufficient to elect him if then cumulatively voted at an election of the entire 
board of directors.

     3.6  PLACE OF MEETINGS; MEETINGS BY TELEPHONE

     Regular meetings of the board of directors may be held at any place within 
or outside the State of Delaware that has been designated from time to time by 
resolution of the board.  In the absence of such a designation, regular 
meetings shall be held at the principal executive office of the corporation. 
Special meetings of the board may be held at any place within or outside the 
State of Delaware that has been designated in the notice of the meeting or, if 
not stated in the notice or if there is no notice, at the principal executive 
office of the corporation.

     Any meeting of the board, regular or special, may be held by conference 
telephone or similar communication equipment, so long as all directors 
participating in the meeting can hear one another; and all such participating 
directors shall be deemed to be present in person at the meeting.

     3.7  FIRST MEETINGS

     The first meeting of each newly elected board of directors shall be held 
at such time and place as shall be fixed by the vote of the stockholders at the 
annual meeting.  In the event of the failure of the stockholders to fix the 
time or place of such first meeting of the newly elected board of directors, or 
in the event such meeting is not held at the time and place so fixed by the 
stockholders, the meeting may be held at such time and place as shall be 
specified in a notice given as hereinafter provided for special 


                                      -9-

<PAGE>

waiver signed by all of the directors.

     3.8  REGULAR MEETINGS

     Regular meetings of the board of directors may be held without notice at 
such time as shall from time to time be determined by the board of directors.  
If any regular meeting day shall fall on a legal holiday, then the meeting 
shall be held at the same time and place on the next succeeding full business 
day.

     3.9  SPECIAL MEETINGS; NOTICE

     Special meetings of the board of directors for any purpose or purposes may 
be called at any time by the chairman of the board, the president, any vice 
president, the secretary or any two directors.

     Notice of the time and place of special meetings shall be delivered 
personally or by telephone to each director or sent by first-class mail, 
telecopy or telegram, charges prepaid, addressed to each director at that 
director's address as it is shown on the records of the corporation.  If the

(4) days before the time of the holding of the meeting.  If the notice is 
delivered personally or by telephone, telecopy or telegram, it shall be 
delivered personally or by telephone or to the telegraph company at least 
forty-eight (48) hours before the time of the holding of the meeting.  Any oral 
notice given personally or by telephone may be communicated either to the 
director or to a person at the office of the director who the person giving the 
notice has reason to believe will promptly communicate it to the director.  The 
notice need not specify the purpose or the place of the meeting, if the meeting 
is to be held at the principal executive office of the corporation.

     3.10 QUORUM

     A majority of the authorized number of directors shall constitute a quorum 
for the transaction of business, except to adjourn as provided in Section 3.12 
of these bylaws.  Every act or decision done or made by a majority of the 
directors present at a duly held meeting at which a quorum is present shall be 
regarded as the act of the board of directors, subject to the provisions of the 
certificate of incorporation and applicable law.

     A meeting at which a quorum is initially present may continue to transact 
business notwithstanding the withdrawal of directors, if any action taken is 
approved by at least a majority of the quorum for that meeting.

     3.11 WAIVER OF NOTICE

     Notice of a meeting need not be given to any director (i) who signs a 
waiver of notice, whether before or after the meeting, or (ii) who attends the 
meeting other than for the express purpose of objecting at the beginning of the 
meeting to the transaction of any business because the meeting is not 


                                      -10-

<PAGE>

lawfully called or convened.  All such waivers shall be filed with the 
corporate records or made part of the minutes of the meeting.  A waiver of 
notice need not specify the purpose of any regular or special meeting of the 
board of directors.

     3.12 ADJOURNMENT

     A majority of the directors present, whether or not constituting a quorum, 
may adjourn any meeting of the board to another time and place.

need not be given unless the meeting is adjourned for more than twenty-four 
(24) hours.  If the meeting is adjourned for more than twenty-four (24) hours, 
then notice of the time and place of the adjourned meeting shall be given

3.9 of these bylaws, to the directors who were not present at the time of the 
adjournment.

     Any action required or permitted to be taken by the board of directors may 
be taken without a meeting, provided that all members of the board individually

     3.15 FEES AND COMPENSATION OF DIRECTORS

     Directors and members of committees may receive such compensation, if any, 
for their services and such reimbursement of expenses as may be fixed or 
determined by resolution of the board of directors.  This Section 3.15 shall 
not be construed to preclude any director from serving the corporation in any 
other capacity as an officer, agent, employee or otherwise and receiving 
compensation for those services.

     3.16 APPROVAL OF LOANS TO OFFICERS

     The corporation may lend money to, or guarantee any obligation of, or 
otherwise assist any officer or other employee of the corporation or any of its 
subsidiaries, including any officer or employee who is a director of the 
corporation or any of its subsidiaries, whenever, in the judgment of the 
directors, such loan, guaranty or assistance may reasonably be expected to

without interest and may be unsecured, or secured in such manner as the board 
of directors shall approve, including, without limitation, a pledge of shares 
of stock of the corporation.  Nothing contained in this section shall be deemed 
to deny, limit or restrict the powers of guaranty or warranty of the 
corporation at common law or under any statute.

     3.17 SOLE DIRECTOR PROVIDED BY CERTIFICATE OF INCORPORATION

     In the event only one director is required by these bylaws or the 
certificate of incorporation, then any reference herein to notices, waivers, 
consents, meetings or other actions by a majority or quorum of the directors 
shall be deemed to refer to such notice, waiver, etc., by such sole director, 
who shall have all the rights and duties and shall be entitled to exercise all 
of the powers and shall assume all the responsibilities otherwise herein 
described as given to the board of directors.

     4.1  COMMITTEES OF DIRECTORS

     The board of directors may, by resolution adopted by a majority of the 
authorized number of directors, designate one (1) or more committees, each 
consisting of two or more directors, to serve at the pleasure of the board.  
The board may designate one (1) or more directors as alternate members of any 
committee, who may replace any absent or disqualified member at any meeting of 
the committee. The appointment of members or alternate members of a committee 
requires the vote of a majority of the authorized number of directors.  Any 
committee, to the extent provided in the resolution of the board, shall have 
and may exercise all the powers and authority of the board, but no such 
committee shall have the power or authority to: (i) amend the certificate of 
incorporation (except that a committee may, to the extent authorized in the 
resolution or resolutions providing for the issuance of shares of stock adopted 
by the board of directors as provided in Section 151(a) of the General 
Corporation Law of Delaware, fix the designations and any of the preferences or 
rights of such shares relating to dividends, redemption, dissolution, any 
distribution of assets of the corporation or the conversion into, or the 
exchange of such shares for, shares of any other class or classes or any other 
series of the same or any other class or classes of stock of the corporation); 
(ii) adopt an agreement of merger or consolida-tion under Sections 251 or 252 
of the General Corporation Law of Delaware; (iii) recommend to the stockholders 
the sale, lease or exchange of all or substantially all of the corporation's

corporation or a revocation of a dissolution; or (v) amend the bylaws of the 
corporation; and, unless the board resolution establishing the committee, the 
bylaws or the certificate of incorporation expressly so provides, no such 
committee shall have the power or authority to declare a dividend, to authorize 
the issuance of stock, or to adopt a certificate of ownership and merger 
pursuant to Section 253 of the General Corporation Law of Delaware.

     4.2  MEETINGS AND ACTION OF COMMITTEES

(regular meetings), Section 3.9 (special meetings; notice), Section 3.10

          INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES
                          AND OTHER AGENTS

     6.1  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The corporation shall, to the maximum extent and in the manner permitted 
by the General Corporation Law of Delaware as the same now exists or may 
hereafter be amended, indemnify any person against expenses (including 
attorneys' fees), judgments, fines, and amounts paid in settlement actually and 
reasonably incurred in connection with any threatened, pending or completed 
action, suit, or proceeding in which such person was or is a party or is 
threatened to be made a party by reason of the fact that such person is or was 
a director or officer of the corporation.  For purposes of this Section 6.1, a 
"director" or "officer" of the corporation shall mean any person (i) who is or 
was a director or officer of the corporation, (ii) who is or was serving at the 
request of the corporation as a director or officer of another corporation, 
partnership, joint venture, trust or other enterprise, or (iii) who was a 
director or officer of a corporation which was a predecessor corporation of the 
corporation or of another enterprise at the request of such predecessor 
corporation.

     The corporation shall be required to indemnify a director or officer in 
connection with an action, suit, or proceeding (or part thereof) initiated by 
such director or officer only if the initiation of such action, suit, or 
proceeding (or part thereof) by the director or officer was authorized by the 
board of directors of the corporation.

     The corporation shall pay the expenses (including attorney's fees) 
incurred by a director or officer of the corporation entitled to 
indemnification hereunder in defending any action, suit or proceeding referred 
to in this Section 6.1 in advance of its final disposition; provided, however, 
that payment of expenses incurred by a director or officer of the corporation 
in advance of the final disposition of such action, suit or proceeding shall be 
made only upon receipt of an undertaking by the director or officer to repay 
all amounts advanced if it should ultimately be determined that the director of 
officer is not entitled to be indemnified under this Section 6.1 or otherwise.

     The rights conferred on any person by this Article VI shall not be 
exclusive of any other rights which such person may have or hereafter acquire 
under any statute, provision of the corporation's certificate of incorporation, 
these bylaws, agreement, vote of the stockholders or disinterested directors or 
otherwise.

     Any repeal or modification of the foregoing provisions of this Article VI 
shall not adversely affect any right or protection hereunder of any person in 
respect of any act or omission occurring prior to the time of such repeal or 
modification.


                                      -17-

     6.2  INDEMNIFICATION OF OTHERS

     The corporation shall have the power, to the maximum extent and in the 
manner permitted by the General Corporation Law of Delaware as the same now 
exists or may hereafter be amended, to indemnify any person (other than 
directors and officers) against expenses (including attorneys' fees), 
judgments, fines, and amounts paid in settlement actually and reasonably 
incurred in connection with any threatened, pending or completed action, suit, 
or proceeding, in which such person was or is a party or is threatened to be 
made a party by reason of the fact that such person is or was an employee or 
agent of the corporation.  For purposes of this Section 6.2, an "employee" or 
"agent" of the corporation (other than a director or officer) shall mean any 
person (i) who is or was an employee or agent of the corporation, (ii) who is 
or was serving at the request of the corporation as an employee or agent of 
another corporation, partnership, joint venture, trust or other enterprise, or 
(iii) who was an employee or agent of a corporation which was a predecessor 
corporation of the corporation or of another enterprise at the request of such 
predecessor corporation.

     6.3  INSURANCE

     The corporation may purchase and maintain insurance on behalf of any 
person who is or was a director, officer, employee or agent of the corporation, 
or is or was serving at the request of the corporation as a director, officer, 
employee or agent of another corporation, partnership, joint venture, trust or 
other enterprise against any liability asserted against him or her and incurred 
by him or her in any such capacity, or arising out of his or her status as 
such, whether or not the corporation would have the power to indemnify him or 
her against such liability under the provisions of the General Corporation Law 
of Delaware.

                             ARTICLE VII

                         RECORDS AND REPORTS

     7.1  MAINTENANCE AND INSPECTION OF RECORDS

     The corporation shall, either at its principal executive office or at such 
place or places as designated by the board of directors, keep a record of its 
stockholders listing their names and addresses and the number and class of 
shares held by each stockholder, a copy of these bylaws as amended to date, 
accounting books and other records of its business and properties.

     Any stockholder of record, in person or by attorney or other agent, shall, 
upon written demand under oath stating the purpose thereof, have the right 
during the usual hours for business to inspect for any proper purpose the 
corporation's stock ledger, a list of its stockholders, and its other books and 
records and to make copies or extracts therefrom.  A proper purpose shall mean 
a purpose reasonably related to such person's interest as a stockholder.  In 
every instance where an attorney or other agent is the person who seeks the 
right to inspection, the demand under oath shall be accompanied by a power 


                                      -18-

<PAGE>

of attorney or such other writing that authorizes the attorney or other agent 
to so act on behalf of the stockholder. The demand under oath shall be directed 
to the corporation at its registered office in Delaware or at its principal 
place of business.

     7.2  INSPECTION BY DIRECTORS

     Any director shall have the right to examine (and to make copies of) the 
corporation's stock ledger, a list of its stockholders and its other books and 
records for a purpose reasonably related to his or her position as a director.

     7.3  ANNUAL STATEMENT TO STOCKHOLDERS

     The board of directors shall present at each annual meeting, and at any 
special meeting of the stockholders when called for by vote of the 
stockholders, a full and clear statement of the business and condition of the 
corporation.

     7.4  REPRESENTATION OF SHARES OF OTHER CORPORATIONS

     The chairman of the board, if any, the president, any vice president, the 
chief financial officer, the secretary or any assistant secretary of this 
corporation, or any other person authorized by the board of directors or the 
president or a vice president, is authorized to vote, represent and exercise on 
behalf of this corporation all rights incident to any and all shares of the 
stock of any other corporation or corporations standing in the name of this 
corporation.  The authority herein granted may be exercised either by such 
person directly or by any other person authorized to do so by proxy or power of 
attorney duly executed by such person having the authority.

     7.5  CERTIFICATION AND INSPECTION OF BYLAWS

     The original or a copy of these bylaws, as amended or otherwise altered to 
date, certified by the secretary, shall be kept at the corporation's principal 
executive office and shall be open to inspection by the stockholders of the 
corporation, at all reasonable times during office hours.

                            ARTICLE VIII

                           GENERAL MATTERS

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

     For purposes of determining the stockholders entitled to receive payment 
of any dividend or other distribution or allotment of any rights or the 
stockholders entitled to exercise any rights in respect of any change, 
conversion or exchange of stock, or for the purpose of any other lawful action, 
the board of directors may fix, in advance, a record date, which shall not 
precede the date upon which the resolution 


                                      -19-

<PAGE>

fixing the record date is adopted and which shall not be more than sixty (60) 
days before any such action.  In that case, only stockholders of record at the 
close of business on the date so fixed are entitled to receive the dividend, 
distribution or allotment of rights, or to exercise such rights, as the case 
may be, notwithstanding any transfer of any shares on the books of the 
corporation after the record date so fixed, except as otherwise provided by law.

     If the board of directors does not so fix a record date, then the record 
date for determining stockholders for any such purpose shall be at the close of 
business on the day on which the board of directors adopts the applicable 
resolution.

     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

     From time to time, the board of directors shall determine by resolution 
which person or persons may sign or endorse all checks, drafts, other orders 
for payment of money, notes or other evidences of indebtedness that are issued 
in the name of or payable to the corporation, and only the persons so 
authorized shall sign or endorse those instruments.

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED

     The board of directors, except as otherwise provided in these bylaws, may 
authorize and empower any officer or officers, or agent or agents, to enter 
into any contract or execute any instrument in the name of and on behalf of the 
corporation; such power and authority may be general or confined to specific 
instances.  Unless so authorized or ratified by the board of directors or 
within the agency power of an officer, no officer, agent or employee shall have 
any power or authority to bind the corporation by any contract or engagement or 
to pledge its credit or to render it liable for any purpose or for any amount.

     8.4  STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES

     The shares of the corporation shall be represented by certificates, 
provided that the board of directors of the corporation may provide by 
resolution or resolutions that some or all of any or all classes or series of 
its stock shall be uncertificated shares.  Any such resolution shall not apply 
to shares represented by a certificate until such certificate is surrendered to 
the corporation.  Notwithstanding the adoption of such a resolution by the 
board of directors, every holder of stock represented by certificates and, upon 
request, every holder of uncertificated shares, shall be entitled to have a 
certificate signed by, or in the name of the corporation by, the chairman or 
vice-chairman of the board of directors, or the president or vice-president, 
and by the treasurer or an assistant treasurer, or the secretary or an 
assistant secretary of such corporation representing the number of shares 
registered in certificate form.  Any or all of the signatures on the 
certificate may be a facsimile.  In case any officer, transfer agent or 
registrar who has signed or whose facsimile signature has been placed upon a 
certificate has ceased to be such officer, transfer agent or registrar before 
such certificate is issued, it may be issued by the corporation with the same 
effect as if he or she were such officer, transfer agent or registrar at the 
date of issue.


                                      -20-

<PAGE>

     Certificates for shares shall be of such form and device as the board of 
directors may designate and shall state the name of the record holder of the 
shares represented thereby; its number; date of issuance; the number of shares 
for which it is issued; a summary statement or reference to the powers, 
designations, preferences or other special rights of such stock and the 
qualifications, limitations or restrictions of such preferences and/or rights, 
if any; a statement or summary of liens, if any; a conspicuous notice of 
restrictions upon transfer or registration of transfer, if any; a statement as 
to any applicable voting trust agreement; if the shares be assessable, or, if 
assessments are collectible by personal action, a plain statement of such facts.

     Upon surrender to the secretary or transfer agent of the corporation of a 
certificate for shares duly endorsed or accompanied by proper evidence of 
succession, assignment or authority to transfer, it shall be the duty of the 
corporation to issue a new certificate to the person entitled thereto, cancel 
the old certificate and record the transaction upon its books.

     The corporation may issue the whole or any part of its shares as partly 
paid and subject to call for the remainder of the consideration to be paid 
therefor.  Upon the face or back of each stock certificate issued to represent 
any such partly paid shares, or upon the books and records of the corporation 
in the case of uncertificated partly paid shares, the total amount of the 
consideration to be paid therefor and the amount paid thereon shall be stated.  
Upon the declaration of any dividend on fully paid shares, the corporation 
shall declare a dividend upon partly paid shares of the same class, but only 
upon the basis of the percentage of the consideration actually paid thereon.

     8.5  SPECIAL DESIGNATION ON CERTIFICATES

     If the corporation is authorized to issue more than one class of stock or 
more than one series of any class, then the powers, the designations, the 
preferences and the relative, participating, optional or other special rights 
of each class of stock or series thereof and the qualifications, limitations or 
restrictions of such preferences and/or rights shall be set forth in full or 
summarized on the face or back of the certificate that the corporation shall 
issue to represent such class or series of stock; provided, however, that, 
except as otherwise provided in Section 202 of the General Corporation Law of 
Delaware, in lieu of the foregoing requirements there may be set forth on the 
face or back of the certificate that the corporation shall issue to represent 
such class or series of stock a statement that the corporation will furnish 
without charge to each stockholder who so requests the powers, the 
designations, the preferences and the relative, participating, optional or 
other special rights of each class of stock or series thereof and the 
qualifications, limitations or restrictions of such preferences and/or rights.

     8.6  LOST CERTIFICATES

     Except as provided in this Section 8.6, no new certificates for shares 
shall be issued to replace a previously issued certificate unless the latter is 
surrendered to the corporation and cancelled at the same time.  The board of 
directors may, in case any share certificate or certificate for any other 
security is lost, stolen or destroyed, authorize the issuance of replacement 
certificates on such terms and conditions as the board may require; the board 
may require indemnification of the corporation secured by a bond or 


                                      -21-

<PAGE>

other adequate security sufficient to protect the corporation against any claim 
that may be made against it, including any expense or liability, on account of 
the alleged loss, theft or destruction of the certificate or the issuance of 
the replacement certificate.

     8.7  TRANSFER AGENTS AND REGISTRARS

     The board of directors may appoint one or more transfer agents or transfer 
clerks, and one or more registrars, each of which shall be an incorporated bank 
or trust company, either domestic or foreign, who shall be appointed at such 
times and places as the requirements of the corporation may necessitate and the 
board of directors may designate.

     8.8  CONSTRUCTION; DEFINITIONS

     Unless the context requires otherwise, the general provisions, rules of 
construction and definitions in the General Corporation Law of Delaware shall 
govern the construction of these bylaws. Without limiting the generality of 
this provision, as used in these bylaws, the singular number includes the 
plural, the plural number includes the singular, and the term "person" includes 
both an entity and a natural person.

                             ARTICLE IX

                             AMENDMENTS

     The original or other bylaws of the corporation may be adopted, amended or 
repealed by the stockholders entitled to vote or by the board of directors of 
the corporation.  The fact that such power has been so conferred upon the 
directors shall not divest the stockholders of the power, nor limit their power 
to adopt, amend or repeal bylaws.

     Whenever an amendment or new bylaw is adopted, it shall be copied in the 
book of bylaws with the original bylaws, in the appropriate place.  If any 
bylaw is repealed, the fact of repeal with the date of the meeting at which the 
repeal was enacted or the filing of the operative written consent(s) shall be 
stated in said book.

                         IMAGYN MEDICAL, INC.

                      INDEMNIFICATION AGREEMENT

    This Indemnification Agreement ("Agreement") is effective as of May __, 
1996 by and between Imagyn Medical, Inc., a Delaware corporation (the 
"Company"), and FIELD(1) ("Indemnitee").

    WHEREAS, effective as of the date hereof, Imagyn Medical, Inc. a 
California corporation, is reincorporating into Delaware;

    WHEREAS, the Company desires to attract and retain the services of highly 
qualified individuals, such as Indemnitee, to serve the Company and its 
related entities;

    WHEREAS, in order to induce Indemnitee to continue to provide services to 
the Company, the Company wishes to provide for the indemnification of, and 
the advancement of expenses to, Indemnitee to the maximum extent permitted by 
law;

    WHEREAS, the Company and Indemnitee recognize the continued difficulty in 
obtaining liability insurance for the Company's directors, officers, 
employees, agents and fiduciaries, the significant increases in the cost of 
such insurance and the general reductions in the coverage of such insurance;

    WHEREAS, the Company and Indemnitee further recognize the substantial 
increase in corporate litigation in general, subjecting directors, officers, 
employees, agents and fiduciaries to expensive litigation risks at the same 
time as the availability and coverage of liability insurance has been 
severely limited; and

    WHEREAS, in connection with the Company's reincorporation, the Company 
and Indemnitee desire to continue to have in place the additional protection 
provided by an indemnification agreement, with such changes as are required 
to conform the existing agreement to Delaware law and to provide 
indemnification and advancement of expenses to the Indemnitee to the maximum 
extent permitted by Delaware law;

    WHEREAS, in view of the considerations set forth above, the Company 
desires that Indemnitee shall be indemnified and advanced expenses by the 
Company as set forth herein;

    NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth 
below.

    1.   CERTAIN DEFINITIONS.

         a.   "Change in Control" shall mean, and shall be deemed to have 
occurred if, on or after the date of this Agreement, (i) any "person" (as 
such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act 
of 1934, as amended), other than a trustee or other fiduciary holding 
securities under an employee benefit plan of the Company acting in such 
capacity or a corporation owned directly or indirectly by the stockholders of 
the Company in substantially the same proportions as their ownership




<PAGE>


of stock of the Company, becomes the "beneficial owner" (as defined in Rule 
13d-3 under said Act), directly or indirectly, of securities of the Company 
representing more than 50% of the total voting power represented by the 
Company's then outstanding Voting Securities, (ii) during any period of two 
consecutive years, individuals who at the beginning of such period constitute 
the Board of Directors of the Company and any new director whose election by 
the Board of Directors or nomination for election by the Company's 
stockholders was approved by a vote of at least two thirds (2/3) of the 
directors then still in office who either were directors at the beginning of 
the period or whose election or nomination for election was previously so 
approved, cease for any reason to constitute a majority thereof, (iii) the 
stockholders of the Company approve a merger or consolidation of the Company 
with any other corporation other than a merger or consolidation which would 
result in the Voting Securities of the Company outstanding immediately prior 
thereto continuing to represent (either by remaining outstanding or by being 
converted into Voting Securities of the surviving entity) at least 80% of the 
total voting power represented by the Voting Securities of the Company or 
such surviving entity outstanding immediately after such merger or 
consolidation, or (iv) the stockholders of the Company approve a plan of 
complete liquidation of the Company or an agreement for the sale or 
disposition by the Company of (in one transaction or a series of related 
transactions) all or substantially all of the Company's assets.

         b.   "Claim" shall mean with respect to a Covered Event:  any 
threatened, pending or completed action, suit, proceeding or alternative 
dispute resolution mechanism, or any hearing, inquiry or investigation that 
Indemnitee in good faith believes might lead to the institution of any such 
action, suit, proceeding or alternative dispute resolution mechanism, whether 
civil, criminal, administrative, investigative or other.

         c.   References to the "Company" shall include, in addition to 
Imagyn Medical, Inc., any constituent corporation (including any constituent 
of a constituent) absorbed in a consolidation or merger to which Imagyn 
Medical, Inc. (or any of its wholly owned subsidiaries) is a party which, if 
its separate existence had continued, would have had power and authority to 
indemnify its directors, officers, employees, agents or fiduciaries, so that 
if Indemnitee is or was a director, officer, employee, agent or fiduciary of 
such constituent corporation, or is or was serving at the request of such 
constituent corporation as a director, officer, employee, agent or fiduciary 
of another corporation, partnership, joint venture, employee benefit plan, 
trust or other enterprise, Indemnitee shall stand in the same position under 
the provisions of this Agreement with respect to the resulting or surviving 
corporation as Indem-nitee would have with respect to such constituent 
corporation if its separate existence had continued.

         d.   "Covered Event" shall mean any event or occurrence related to 
the fact that Indemnitee is or was a director, officer, employee, agent or 
fiduciary of the Company, or any subsidiary of the Company, or is or was 
serving at the request of the Company as a director, officer, employee, agent 
or fiduciary of another corporation, partnership, joint venture, trust or 
other enterprise, or by reason of any action or inaction on the part of 
Indemnitee while serving in such capacity.

         e.   "Expenses" shall mean any and all expenses (including 
attorneys' fees and all other costs, expenses and obligations incurred in 
connection with investigating, defending, being a witness in or participating 
in (including on appeal), or preparing to defend, to be a witness in or to 
participate in, any action, suit, proceeding, alternative dispute resolution 
mechanism, hearing, inquiry or investigation),


                                     -2-

<PAGE>


judgments, fines, penalties and amounts paid in settlement (if such settlement 
is approved in advance by the Company, which approval shall not be 
unreasonably withheld) of any Claim and any federal, state, local or foreign 
taxes imposed on the Indemnitee as a result of the actual or deemed receipt 
of any payments under this Agreement.

         f.   "Expense Advance" shall mean a payment to Indemnitee pursuant 
to Section 3 of Expenses in advance of the settlement of or final judgement 
in any action, suit, proceeding or alternative dispute resolution mechanism, 
hearing, inquiry or investigation which constitutes a Claim.

         g.   "Independent Legal Counsel" shall mean an attorney or firm of 
attorneys, selected in accordance with the provisions of Section 2(d) hereof, 
who shall not have otherwise performed services for the Company or 
Indemnitee within the last three years (other than with respect to matters 
concerning the rights of Indemnitee under this Agreement, or of other 
Indemnitees under similar indemnity agreements).

         h.   References to "other enterprises" shall include employee 
benefit plans; references to "fines" shall include any excise taxes assessed 
on Indemnitee with respect to an employee benefit plan; and references to 
"serving at the request of the Company" shall include any service as a 
director, officer, employee, agent or fiduciary of the Company which imposes 
duties on, or involves services by, such director, officer, employee, agent 
or fiduciary with respect to an employee benefit plan, its participants or 
its beneficiaries; and if Indemnitee acted in good faith and in a manner 
Indemnitee reasonably believed to be in the interest of the participants and 
beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have 
acted in a manner "not opposed to the best interests of the Company"  as 
referred to in this Agreement.

         i.   "Reviewing Party" shall mean, subject to the provisions of 
Section 2(d), any person or body appointed by the Board of Directors in 
accordance with applicable law to review the Company's obligations hereunder 
and under applicable law, which may include a member or members of the 
Company's Board of Directors, Independent Legal Counsel or any other person 
or body not a party to the particular Claim for which Indemnitee is seeking 
indemnification.

         j.   "Section" refers to a section of this Agreement unless 
otherwise indicated.

         k.   "Voting Securities" shall mean any securities of the Company 
that vote generally in the election of directors.

    2.   INDEMNIFICATION.

         a.   INDEMNIFICATION OF EXPENSES.  Subject to the provisions of 
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to 
the fullest extent permitted by law if Indemnitee was or is or becomes a 
party to or witness or other participant in, or is threatened to be made a 
party to or witness or other participant in, any Claim (whether by reason of 
or arising in part out of a Covered Event), including all interest, 
assessments and other charges paid or payable in connection with or in 
respect of such Expenses.  


                                     -3-

<PAGE>


         b.   REVIEW OF INDEMNIFICATION OBLIGATIONS.  Notwithstanding the 
foregoing, in the event any Reviewing Party shall have determined (in a 
written opinion, in any case in which Independent Legal Counsel is the 
Reviewing Party) that Indemnitee is not entitled to be indemnified hereunder 
under applicable law, (i) the Company shall have no further obligation under 
Section 2(a) to make any payments to Indemnitee not made prior to such 
determination by such Reviewing Party, and (ii) the Company shall be entitled 
to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company) 
for all Expenses theretofore paid to Indemnitee to which Indemnitee is not 
entitled hereunder under applicable law; PROVIDED, HOWEVER, that if 
Indemnitee has commenced or thereafter commences legal proceedings in a court 
of competent jurisdiction to secure a determination that Indemnitee is 
entitled to be indemnified hereunder under applicable law, any determination 
made by any Reviewing Party that Indemnitee is not entitled to be indemnified 
hereunder under applicable law shall not be binding and Indemnitee shall not 
be required to reimburse the Company for any Expenses theretofore paid in 
indemnifying Indemnitee until a final judicial determination is made with 
respect thereto (as to which all rights of appeal therefrom have been 
exhausted or lapsed).  Indemnitee's obligation to reimburse the Company for 
any Expenses shall be unsecured and no interest shall be charged thereon. 

         c.   INDEMNITEE RIGHTS ON UNFAVORABLE DETERMINATION; BINDING EFFECT. 
If any Reviewing Party determines that Indemnitee substantively is not 
entitled to be indemnified hereunder in whole or in part under applicable 
law, Indemnitee shall have the right to commence litigation seeking an 
initial determination by the court or challenging any such determination by 
such Reviewing Party or any aspect thereof, including the legal or factual 
bases therefor, and, subject to the provisions of Section 15, the Company 
hereby consents to service of process and to appear in any such proceeding. 
Absent such litigation, any determination by any Reviewing Party shall be 
conclusive and binding on the Company and Indemnitee.

         d.   SELECTION OF REVIEWING PARTY; CHANGE IN CONTROL.  If there has 
not been a Change in Control, any Reviewing Party shall be selected by the 
Board of Directors, and if there has been such a Change in Control (other 
than a Change in Control which has been approved by a majority of the 
Company's Board of Directors who were directors immediately prior to such 
Change in Control), any Reviewing Party with respect to all matters 
thereafter arising concerning the rights of Indemnitee to indemnification of 
Expenses under this Agreement or any other agreement or under the Company's 
Certificate of Incorporation or Bylaws as now or hereafter in effect, or 
under any other applicable law, if desired by Indemnitee, shall be 
Independent Legal Counsel selected by Indemnitee and approved by the Company 
(which approval shall not be unreasonably withheld).  Such counsel, among 
other things, shall render its written opinion to the Company and Indemnitee 
as to whether and to what extent Indemnitee would be entitled to be 
indemnified hereunder under applicable law and the Company agrees to abide by 
such opinion.  The Company agrees to pay the reasonable fees of the 
Independent Legal Counsel referred to above and to indemnify fully such 
counsel against any and all expenses (including attorneys' fees), claims, 
liabilities and damages arising out of or relating to this Agreement or its 
engagement pursuant hereto.  Notwithstanding any other provision of this 
Agreement, the Company shall not be required to pay Expenses of more than one 
Independent Legal Counsel in connection with all matters concerning a single 
Indemnitee, and such Independent Legal Counsel shall be the Independent Legal 
Counsel for any or all other Indemnitees unless (i) the employment of 
separate counsel by one or more Indemnitees has been previously authorized by 
the Company in writing, or (ii) an Indemnitee shall


                                     -4-

<PAGE>


have provided to the Company a written statement that such Indemnitee has 
reasonably concluded that there may be a conflict of interest between such 
Indemnitee and the other Indemnitees with respect to the matters arising 
under this Agreement.

         e.   MANDATORY PAYMENT OF EXPENSES.  Notwithstanding any other 
provision of this Agreement other than Section 10 hereof, to the extent that 
Indemnitee has been successful on the merits or otherwise, including, without 
limitation, the dismissal of an action without prejudice, in defense of any 
Claim, Indemnitee shall be indemnified against all Expenses incurred by 
Indemnitee in connection therewith.

    3.   EXPENSE ADVANCES.   
         a.   OBLIGATION TO MAKE EXPENSE ADVANCES.  Upon receipt of a written 
undertaking by or on behalf of the Indemnitee to repay such amounts if it 
shall ultimately be determined that the Indemnitee is not entitled to be 
indemnified therefore by the Company hereunder under applicable law, the 
Company shall make Expense Advances to Indemnitee.

         b.   FORM OF UNDERTAKING.  Any obligation to repay any Expense 
Advances hereunder pursuant to a written undertaking by the Indemnitee shall 
be unsecured and no interest shall be charged thereon.

         c.   DETERMINATION OF REASONABLE EXPENSE ADVANCES.  The parties 
agree that for the purposes of any Expense Advance for which Indemnitee has 
made written demand to the Company in accordance with this Agreement, all 
Expenses included in such Expense Advance that are certified by affidavit of 
Indemnitee's counsel as being reasonable shall be presumed conclusively to be 
reasonable.

    4.   PROCEDURES FOR INDEMNIFICATION AND EXPENSE ADVANCES.

         a.   TIMING OF PAYMENTS.  All payments of Expenses (including 
without limitation Expense Advances) by the Company to the Indemnitee 
pursuant to this Agreement shall be made to the fullest extent permitted by 
law as soon as practicable after written demand by Indemnitee therefor is 
presented to the Company, but in no event later than thirty (30) business 
days after such written demand by Indemnitee is presented to the Company, 
except in the case of Expense Advances, which shall be made no later than ten 
(10) business days after such written demand by Indemnitee is presented to 
the Company.  

         b.   NOTICE/COOPERATION BY INDEMNITEE.  Indemnitee shall, as a 
condition precedent to Indemnitee's right to be indemnified or Indemnitee's 
right to receive Expense Advances under this Agreement, give the Company 
notice in writing as soon as practicable of any Claim made against Indemnitee 
for which indemnification will or could be sought under this Agreement.  
Notice to the Company shall be directed to the Chief Executive Officer of the 
Company at the address shown on the signature page of this Agreement (or such 
other address as the Company shall designate in writing to Indemnitee).  In 
addition, Indemnitee shall give the Company such information and cooperation 
as it may reasonably require and as shall be within Indemnitee's power.


                                     -5-

<PAGE>


         c.   NO PRESUMPTIONS; BURDEN OF PROOF.  For purposes of this 
Agreement, the termination of any Claim by judgment, order, settlement 
(whether with or without court approval) or conviction, or upon a plea of 
NOLO CONTENDERE, or its equivalent, shall not create a presumption that 
Indemnitee did not meet any particular standard of conduct or have any 
particular belief or that a court has determined that indemnification is not 
permitted by this Agreement or applicable law.  In addition, neither the 
failure of any Reviewing Party to have made a determination as to whether 
Indemnitee has met any particular standard of conduct or had any particular 
belief, nor an actual determination by any Reviewing Party that Indemnitee 
has not met such standard of conduct or did not have such belief, prior to 
the commencement of legal proceedings by Indemnitee to secure a judicial 
determination that Indemnitee should be indemnified under this Agreement 
under applicable law, shall be a defense to Indemnitee's claim or create a 
presumption that Indemnitee has not met any particular standard of conduct or 
did not have any particular belief.  In connection with any determination by 
any Reviewing Party or otherwise as to whether the Indemnitee is entitled to 
be indemnified hereunder under applicable law, the burden of proof shall be 
on the Company to establish that Indemnitee is not so entitled.

         d.   NOTICE TO INSURERS.  If, at the time of the receipt by the 
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company 
has liability insurance in effect which may cover such Claim, the Company 
shall give prompt notice of the commencement of such Claim to the insurers in 
accordance with the procedures set forth in the respective policies.  The 
Company shall thereafter take all necessary or desirable action to cause such 
insurers to pay, on behalf of the Indemnitee, all amounts payable as a result 
of such Claim in accordance with the terms of such policies.

         e.   SELECTION OF COUNSEL.  In the event the Company shall be 
obligated hereunder to provide indemnification for or make any Expense 
Advances with respect to the Expenses of any Claim, the Company, if 
appropriate, shall be entitled to assume the defense of such Claim with 
counsel approved by Indemnitee (which approval shall not be unreasonably 
withheld) upon the delivery to Indemnitee of written notice of the Company's 
election to do so.  After delivery of such notice, approval of such counsel 
by Indemnitee and the retention of such counsel by the Company, the Company 
will not be liable to Indemnitee under this Agreement for any fees or 
expenses of separate counsel subsequently retained by or on behalf of 
Indemnitee with respect to the same Claim; provided that, (i) Indemnitee 
shall have the right to employ Indemnitee's separate counsel in any such 
Claim at Indemnitee's expense and (ii) if (A) the employment of separate 
counsel by Indemnitee has been previously authorized by the Company, (B) 
Indemnitee shall have reasonably concluded that there may be a conflict of 
interest between the Company and Indemnitee in the conduct of any such 
defense, or (C) the Company shall not continue to retain such counsel to 
defend such Claim, then the fees and expenses of Indemnitee's separate 
counsel shall be Expenses for which Indemnitee may receive indemnification or 
Expense Advances hereunder.

    5.   ADDITIONAL INDEMNIFICATION RIGHTS; NONEXCLUSIVITY.

         a.   SCOPE.  The Company hereby agrees to indemnify the Indemnitee 
to the fullest extent permitted by law, notwithstanding that such 
indemnification is not specifically authorized by the other provisions of 
this Agreement, the Company's Certificate of Incorporation, the Company's 
Bylaws or by statute.  In the event of any change after the date of this 
Agreement in any applicable law, statute or rule which expands the right of a 
Delaware corporation to indemnify a member of its board of direc-tors or an 
officer, employee, agent or fiduciary, it is the intent of the parties hereto 
that Indemnitee shall enjoy by this Agreement the greater benefits afforded 
by such change.  In the event of any change in any applicable law, statute or 
rule which narrows the right of a Delaware corporation to indemnify a member 
of its board of directors


                                     -6-

<PAGE>


or an officer, employee, agent or fiduciary, such change, to the extent not 
otherwise required by such law, statute or rule to be applied to this 
Agreement, shall have no effect on this Agreement or the parties' rights and 
obligations hereunder except as set forth in Section 10(a) hereof.

         b.   NONEXCLUSIVITY.  The indemnification and the payment of Expense 
Advances provided by this Agreement shall be in addition to any rights to 
which Indemnitee may be entitled under the Company's Certificate of 
Incorporation, its Bylaws, any other agreement, any vote of stockholders or 
disinterested directors, the General Corporation Law of the State of 
Delaware, or otherwise.  The indemnification and the payment of Expense 
Advances provided under this Agreement shall continue as to Indemnitee for 
any action taken or not taken while serving in an indemnified capacity even 
though subsequent thereto Indemnitee may have ceased to serve in such 
capacity.

    6.   NO DUPLICATION OF PAYMENTS.  The Company shall not be liable under 
this Agreement to make any payment in connection with any Claim made against 
Indemnitee to the extent Indemnitee has otherwise actually received payment 
(under any insurance policy, provision of the Company's Certificate of 
Incorporation, Bylaws or otherwise) of the amounts otherwise payable 
hereunder.

    7.   PARTIAL INDEMNIFICATION.  If Indemnitee is entitled under any 
provision of this Agreement to indemnification by the Company for some or a 
portion of Expenses incurred in connection with any Claim, but not, however, 
for all of the total amount thereof, the Company shall nevertheless indemnify 
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

    8.   MUTUAL ACKNOWLEDGMENT.  Both the Company and Indemnitee acknowledge 
that in certain instances, federal law or applicable public policy may 
prohibit the Company from indemnifying its directors, officers, employees, 
agents or fiduciaries under this Agreement or otherwise.  Indemnitee 
understands and acknowledges that the Company has undertaken or may be 
required in the future to undertake with the Securities and Exchange 
Commission to submit the question of indemnification to a court in certain 
circumstances for a determination of the Company's right under public policy 
to indemnify Indemnitee.

    9.   LIABILITY INSURANCE.  To the extent the Company maintains liability 
insurance applicable to directors, officers, employees, agents or 
fiduciaries, Indemnitee shall be covered by such policies in such a manner as 
to provide Indemnitee the same rights and benefits as are provided to the 
most favorably insured of the Company's directors, if Indemnitee is a 
director; or of the Company's officers, if Indemnitee is not a director of 
the Company but is an officer; or of the Company's key employees, agents or 
fiduciaries, if Indemnitee is not an officer or director but is a key 
employee, agent or fiduciary.

    10.  EXCEPTIONS.  Notwithstanding any other provision of this Agreement, 
the Company shall not be obligated pursuant to the terms of this Agreement:

         a.   EXCLUDED ACTION OR OMISSIONS.  To indemnify or make Expense 
Advances to


                                     -7-

<PAGE>


Indemnitee with respect to Claims arising out of acts, omissions or 
transactions for which Indemnitee is prohibited from receiving 
indemnification under applicable law. 

         b.   CLAIMS INITIATED BY INDEMNITEE.  To indemnify or make Expense 
Advances to Indemnitee with respect to Claims initiated or brought 
voluntarily by Indemnitee and not by way of defense, counterclaim or 
crossclaim, except (i) with respect to actions or proceedings brought to 
establish or enforce a right to indemnification under this Agreement or any 
other agreement or insurance policy or under the Company's Certificate of 
Incorporation or Bylaws now or hereafter in effect relating to Claims for 
Covered Events, (ii) in specific cases if the Board of Directors has approved 
the initiation or bringing of such Claim, or (iii) as otherwise required 
under Section 145 of the Delaware General Corporation Law, regardless of 
whether Indemnitee ultimately is determined to be entitled to such 
indemnification, Expense Advances, or insurance recovery, as the case may be.

         c.   LACK OF GOOD FAITH.  To indemnify Indemnitee for any Expenses 
incurred by the Indemnitee with respect to any action instituted (i) by 
Indemnitee to enforce or interpret this Agreement, if a court having 
jurisdiction over such action determines as provided in Section 13 that each 
of the material assertions made by the Indemnitee as a basis for such action 
was not made in good faith or was frivolous, or (ii) by or in the name of the 
Company to enforce or interpret this Agreement, if a court having 
jurisdiction over such action determines as provided in Section 13 that each 
of the material defenses asserted by Indemnitee in such action was made in 
bad faith or was frivolous.

         d.   CLAIMS UNDER SECTION 16(b).  To indemnify Indemnitee for 
Expenses and the payment of profits arising from the purchase and sale by 
Indemnitee of securities in violation of Section 16(b) of the Securities 
Exchange Act of 1934, as amended, or any similar successor statute.

    11.  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, each of which shall constitute an original.

    12.  BINDING EFFECT; SUCCESSORS AND ASSIGNS.  This Agreement shall be 
binding upon and inure to the benefit of and be enforceable by the parties 
hereto and their respective successors, assigns (including any direct or 
indirect successor by purchase, merger, consolidation or otherwise to all or 
substantially all of the business or assets of the Company), spouses, heirs 
and personal and legal representatives.  The Company shall require and cause 
any successor (whether direct or indirect, and whether by purchase, merger, 
consolidation or otherwise) to all, substantially all, or a substantial part, 
of the business or assets of the Company, by written agreement in form and 
substance satisfactory to Indemnitee, expressly to assume and agree to 
perform this Agreement in the same manner and to the same extent that the 
Company would be required to perform if no such succession had taken place.  
This Agreement shall continue in effect regardless of whether Indemnitee 
continues to serve as a director, officer, employee, agent or fiduciary (as 
applicable) of the Company or of any other enterprise at the Company's 
request.

    13.  EXPENSES INCURRED IN ACTION RELATING TO ENFORCEMENT OR 
INTERPRETATION.  In the event that any action is instituted by Indemnitee 
under this Agreement or under any liability insurance policies maintained by 
the Company to enforce or interpret any of the terms hereof or thereof, 
Indemnitee shall


                                     -8-

<PAGE>


be entitled to be indemnified for all Expenses incurred by Indemnitee with 
respect to such action (including without limitation attorneys' fees), 
regardless of whether Indemnitee is ultimately successful in such action, 
unless as a part of such action a court having jurisdiction over such action 
makes a final judicial determination (as to which all rights of appeal 
therefrom have been exhausted or lapsed) that each of the material assertions 
made by Indemnitee as a basis for such action was not made in good faith or 
was frivolous; provided, however, that until such final judicial 
determination is made, Indemnitee shall be entitled under Section 3 to 
receive payment of Expense Advances hereunder with respect to such action.  
In the event of an action instituted by or in the name of the Company under 
this Agreement to enforce or interpret any of the terms of this Agreement, 
Indemnitee shall be entitled to be indemnified for all Expenses incurred by 
Indemnitee in defense of such action (including without limitation costs and 
expenses incurred with respect to Indemnitee's counterclaims and cross-claims 
made in such action), unless as a part of such action a court having 
jurisdiction over such action makes a final judicial determination (as to 
which all rights of appeal therefrom have been exhausted or lapsed) that each 
of the material defenses asserted by Indemnitee in such action was made in 
bad faith or was frivolous; provided, however, that until such final judicial 
determination is made, Indemnitee shall be entitled under Section 3 to 
receive payment of Expense Advances hereunder with respect to such action.

    14.  PERIOD OF LIMITATIONS.  No legal action shall be brought and no 
cause of action shall be asserted by or in the right of the Company against 
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or 
legal representatives after the expiration of two years from the date of 
accrual of such cause of action, and any claim or cause of action of the 
Company shall be extinguished and deemed released unless asserted by the 
timely filing of a legal action within such two year period; provided, 
however, that if any shorter period of limitations is otherwise applicable to 
any such cause of action, such shorter period shall govern.

    15.  NOTICE.  All notices, requests, demands and other communications 
under this Agreement shall be in writing and shall be deemed duly given (i) 
if delivered by hand and signed for by the party addressed, on the date of 
such delivery, or (ii) if mailed by domestic certified or registered mail 
with postage prepaid, on the third business day after the date postmarked.  
Addresses for notice to either party are as shown on the signature page of 
this Agreement, or as subsequently modified by written notice.

    16.  CONSENT TO JURISDICTION.  The Company and Indemnitee each hereby 
irrevocably consent to the jurisdiction of the courts of the State of 
Delaware for all purposes in connection with any action or proceeding which 
arises out of or relates to this Agreement and agree that any action 
instituted under this Agreement shall be commenced, prosecuted and continued 
only in the Court of Chancery of the State of Delaware in and for New Castle 
County, which shall be the exclusive and only proper forum for adjudicating 
such a claim.

    17.  SEVERABILITY.  The provisions of this Agreement shall be severable 
in the event that any of the provisions hereof (including any provision 
within a single section, paragraph or sentence) are held by a court of 
competent jurisdiction to be invalid, void or otherwise unenforceable, and 
the remaining provisions shall remain enforceable to the fullest extent 
permitted by law.  Furthermore, to the fullest extent possible, the 
provisions of this Agreement (including without limitation each portion of 
this Agreement containing any provision held to be invalid, void or otherwise 
unenforceable, that is not itself


                                     -9-

<PAGE>


invalid, void or unenforceable) shall be construed so as to give effect to 
the intent manifested by the provision held invalid, illegal or unenforceable.

    18.  CHOICE OF LAW.  This Agreement, and all rights, remedies, 
liabilities, powers and duties of the parties to this Agreement, shall be 
governed by and construed in accordance with the laws of the State of 
Delaware as applied to contracts between Delaware residents entered into and 
to be performed entirely in the State of Delaware without regard to 
principles of conflicts of laws.

    19.  SUBROGATION.  In the event of payment under this Agreement, the 
Company shall be subrogated to the extent of such payment to all of the 
rights of recovery of Indemnitee, who shall execute all documents required 
and shall do all acts that may be necessary to secure such rights and to 
enable the Company effectively to bring suit to enforce such rights.

    20.  AMENDMENT AND TERMINATION.  No amendment, modification, termination 
or cancellation of this Agreement shall be effective unless it is in writing 
signed by both the parties hereto.  No waiver of any of the provisions of 
this Agreement shall be deemed to be or shall constitute a waiver of any 
other provisions hereof (whether or not similar), nor shall such waiver 
constitute a continuing waiver.

    21.  INTEGRATION AND ENTIRE AGREEMENT.  This Agreement sets forth the 
entire understanding between the parties hereto and supersedes and merges all 
previous written and oral negotiations, commitments, understandings and 
agreements relating to the subject matter hereof between the parties hereto.

    22.  NO CONSTRUCTION AS EMPLOYMENT AGREEMENT.  Nothing contained in this 
Agreement shall be construed as giving Indemnitee any right to be retained in 
the employ of the Company or any of its subsidiaries or affiliated entities.  


                                    -10-
