                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and the Financial Statements and Notes thereto appearing elsewhere
in this Prospectus. The Company was formed in April 1996, and in May 1996, it
acquired its assets and technologies in connection with a business combination.
All references herein to Interact Medical Technologies Corporation ("Interact"
or the "Company") also shall be deemed to be references to the Company and its
predecessors, Ixion, Inc. ("Ixion") and Medical Media Systems ("MMS"). See "The
Company."
 
                                  THE COMPANY
 
     Interact develops, markets and manufactures products designed to facilitate
the effective use of minimally invasive surgical ("MIS") procedures and enhance
clinical performance. The Company's initial product, Preview(TM), was launched
in June 1996. Preview provides the clinician with a detailed three-dimensional
model of the patient-specific anatomy manufactured by processing computed
tomography ("CT") or magnetic resonance ("MR") images on the Company's
proprietary software platform at its production facility. The Company delivers
its Preview models to the clinician embodied in user-friendly proprietary
viewing software that can be run on a Macintosh personal computer. The model and
the viewing software augment traditional two-dimensional medical imaging tools
and allow the clinician, without significant computer expertise, to manipulate
information, perform measurements and conduct pre-surgical planning for use
primarily in MIS procedures.
 
     The Company is also currently field testing a pre-production prototype of
GastroSim(TM), an interactive virtual reality ("IVR") simulator for teaching and
training clinicians. GastroSim is designed to figuratively place the clinician
inside the upper and lower gastrointestinal tracts of a "virtual" patient and
allow the clinician to perform a number of simulated MIS procedures using
realistic medical instruments and devices.
 
     The Company has a multi-faceted business relationship with Baxter
Healthcare Corporation ("Baxter"). A wholly-owned subsidiary of Baxter is a
principal stockholder of the Company and previously invested approximately $7.1
million in the development of the visualization technology upon which Preview is
based. In May 1996, the Company entered into a distribution agreement with
Baxter pursuant to which Baxter obtained an exclusive right to sell Preview for
use in connection with treating aortic and iliac aneurysms (except with regard
to sales to parties developing or manufacturing devices specifically designed
for endovascular treatment of aortic aneurysms for which Baxter's rights are
co-exclusive with the Company), including abdominal aortic aneurysms ("AAA").
Baxter has loans outstanding to the Company in the principal amount of $2.55
million of which $2.0 million together with certain accrued interest will be
converted into Common Stock upon the closing of this Offering (assuming such
closing takes place prior to September 1, 1996), and the remaining $550,000
together with certain accrued interest will be repaid in cash. After this
Offering, Baxter, together with a wholly-owned subsidiary will own approximately
19.7% of the outstanding Common Stock of the Company. See "Use of Proceeds" and
"Certain Transactions."
 
     MIS procedures have revolutionized some areas of surgery, and the
advantages of MIS approaches over open surgical techniques (including reduced
trauma, complications, pain and suffering, convalescence time, procedure time
and ultimately lower overall medical costs), suggest that MIS procedures could
eventually be adopted in place of numerous other open surgical procedures. The
Company believes the growth in MIS procedures is being accelerated by today's
healthcare environment, in which more cost effective means for clinicians to
deliver services are aggressively being sought. Despite the benefits of
minimally invasive surgery, only select MIS procedures have attained widespread
adoption. In 1995, MIS procedures accounted for approximately 15% of the
surgical procedures performed in the United States. The Company believes that
its products will help address two of the major impediments to the widespread
adoption and performance of many additional MIS procedures. First, in performing
MIS procedures, parts of the physical anatomy that can be visualized and
manipulated during traditional surgeries are hidden from the eye and must be
handled remotely. Second, MIS procedures require proficiency in novel surgical
techniques potentially involving specialized MIS instruments and devices.
 
                                        3
<PAGE>   6
 
     Preview allows the clinician to visualize and plan surgical procedures by
using a three-dimensional model of the patient-specific anatomy. Although
Preview has been tested clinically to model most parts of the human anatomy,
initial marketing efforts have focused on the application of Preview to planning
surgical procedures to treat AAA. AAAs are lifethreatening aneurysms which form
in the abdominal aorta. The National Center for Health Care Statistics estimates
that approximately 1.5 million people in the United States have AAA, with
approximately 190,000 new patients diagnosed with AAA each year. The Company
believes that due to the drawbacks of open surgery, the recommended course of
treatment for AAA will ultimately be an MIS procedure. The Company believes that
Preview's ability to generate three-dimensional representations and present
thousands more pre-operative images than traditional imaging methods provides
clinicians with a valuable perspective for use in planning MIS procedures.
 
     As an outgrowth of Preview, the Company is also developing DataFusion(TM),
a product designed to aid the clinician with visualization and navigation during
the performance of actual MIS procedures. DataFusion will use proprietary
software to track surgical instruments and overlay live images of a patient's
anatomy on the same three-dimensional model used in Preview. By helping the
clinician to compensate for the inability to directly visualize and manipulate
the operative area, the Company believes that Preview, (and DataFusion once
developed), will improve the results of MIS procedures and enable the
application of MIS technology to additional surgical procedures.
 
     GastroSim is designed to create realistic clinical experiences for training
clinicians to conduct diagnostic tests and therapy on ulcers, polyps, cancers,
bile stone removals, bronchoscopies, endotracheal tube placements and ultrasound
echocardial procedures and in using sophisticated MIS instruments and devices.
Although the Company's initial market focus for its IVR simulator technology
will be on procedures typically performed in the areas of gastroenterology and
family practice medicine, the Company plans to apply its core IVR technology to
develop simulators designed to replicate MIS procedures utilized by clinicians
in a number of clinical specialties, including cardiology, cardiac surgery,
interventional radiology, urology, obstetrics/gynecology, neurosurgery and
various micro minimally invasive procedures such as functional endoscopic sinus
surgery. By allowing the clinician to replicate a multitude of complex surgical,
diagnostic and therapeutic procedures without the need for live patients,
cadavers or animals, the IVR simulators the Company intends to develop can be
anticipated to increase the number of physicians capable of performing advanced
MIS procedures, improve the general level of competency of clinicians performing
MIS procedures and help safely and expeditiously make MIS procedures more widely
available.
 
     The Company has received 510(k) clearance from the United States Food and
Drug Administration ("FDA") for the use of Preview. This FDA clearance allows
the Company to use Preview to model many anatomical regions. The Company does
not believe that its GastroSim product will require FDA approval.
 
     The Company's objective is to capitalize on advances in software and
medical imaging to become a leading provider of interactive products to promote
the effective use of MIS procedures. The Company's strategy is comprised of the
following key elements: (i) gain acceptance for use of Preview in planning AAA
procedures; (ii) bring GastroSim to production and establish it and other IVR
simulators as a standard for use in teaching, training and credentialing
clinicians to perform a variety of MIS procedures and other diagnostic and
therapeutic techniques; (iii) develop new products and new applications for
Preview and the Company's IVR simulator technology; and (iv) minimize upfront
investment costs to customers.

     outstanding warrants. See "Capitalization," "Management--Benefit Plans,"

(2) Includes 244,455 shares of Common Stock to be issued immediately following
     the closing of this Offering to investors in Ixion's 1995 Bridge Financing
     (the "Bridge Financing"). Such number of shares is calculated by dividing
     the approximately $2,200,000 of Common Stock the investors in the Bridge
     Financing are entitled to receive immediately following the closing of this
     Offering pursuant to the terms of certain agreements between the Company
     and such investors (the "Letter Agreements"), by the initial public
     offering price for the sale of shares of Common Stock offered hereby
     (assuming an initial public offering price of $9.00 per share (the midpoint
     of the range set forth on the cover page of this Prospectus)).
 
(3) Includes 38,889 shares of Common Stock to be issued immediately following
     the closing of this Offering to Baxter. Such number of shares is calculated
     by dividing the $350,000 of Common Stock Baxter is entitled to receive
     immediately following the closing of this Offering pursuant to the terms of
     a certain agreement between the Company and Baxter (the "Baxter Letter"),
     by the initial public offering price for the sale of shares of Common Stock
     offered hereby (assuming an initial public offering price of $9.00 per
     share (the midpoint of the range set forth on the cover page of this
     Prospectus)).
 
(4) Includes 227,964 shares of Common Stock to be issued immediately following
     the closing of this Offering to Baxter in the event that such closing
     occurs prior to September 1, 1996. Such number of shares is calculated by
     dividing the $2,000,000 principal amount of a promissory note issued by the
     Company to Baxter on May 24, 1996 (the "$2,000,000 Note"), plus accrued
     interest calculated at a rate of 200 basis points above the prime rate
     (assuming that the closing of this Offering occurs on August 24, 1996), by
     the initial public offering price (assuming an initial public offering
     price of $9.00 per share (the midpoint of the range set forth on the cover
     page of this Prospectus)).

                         SUMMARY FINANCIAL INFORMATION
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
     The following should be read in conjunction with the Financial Statements,
Management's Discussion and Analysis of Financial Condition and Results of
Operations, and Pro Forma Financial Information presented elsewhere in this
Prospectus.
 
     Interact was formed in April 1996, and in May 1996, it acquired its assets
and technologies in connection with a business combination involving Ixion and
MMS. Inasmuch as former Ixion stockholders own the majority of Interact capital
stock after the business combination, Ixion is considered to be the acquiring
corporation for purposes of purchase accounting and the predecessor entity to
Interact for purposes of financial reporting. When Interact financial statements
are presented as of and for periods subsequent to the business combination, the
Interact financial statements for periods prior to the business combination will
be those of what was formerly Ixion.
 
                   INTERACT MEDICAL TECHNOLOGIES CORPORATION
 
     As more fully described in the Pro Forma Condensed Financial Information
appearing elsewhere in this Prospectus, the Company's unaudited Pro Forma
Balance Sheet Data at March 31, 1996, gives effect to (i) the contribution of
MMS partnership interests to Interact and merger of Ixion with and into
Interact, (ii) the issuance of Common Stock in exchange for certain accrued
amounts payable, and (iii) receipt of $2.0 million cash pursuant to a
convertible note payable to Baxter, as if such transactions had occurred as of
March 31, 1996. The Company's unaudited Pro Forma Statements of Operations Data
for the year ended December 31, 1995 and for the three months ended March 31,
1996 include the results of operations of Ixion and MMS for the respective
periods presented and give effect to pro forma adjustments as if the
aforementioned transactions had occurred at the beginning of the respective
periods. These Pro Forma Condensed Financial Statements are not necessarily
indicative of future financial positions or results of operations of the
Company.

                                  THE COMPANY
 
COMPANY BACKGROUND
 
     Interact develops, markets and manufactures products designed to facilitate
the effective use of MIS procedures and enhance clinical performance. The
Company's initial product, Preview, was launched in June 1996. Preview provides
the clinician with a detailed three-dimensional model of the patient-specific
anatomy manufactured by processing CT or MR images on the Company's proprietary
software platform at its production facility. The Company delivers its Preview
models to the clinician embodied in user-friendly proprietary viewing software
that can be run on a Macintosh personal computer. The model and the viewing
software augment traditional two-dimensional medical imaging tools and allow the
clinician, without significant computer expertise, to manipulate information,
perform measurements and conduct presurgical planning for use primarily in MIS
procedures.
 
     The Company is also currently field testing a pre-production prototype of
GastroSim, an IVR simulator for teaching and training clinicians. GastroSim is
designed to figuratively place the clinician inside the upper and lower
gastrointestinal tracts of a "virtual" patient and allow the clinician to
perform a number of simulated MIS procedures using realistic medical instruments
and devices.
 
     The Company was incorporated in April 1996. The Company's principal
executive offices are located at 654 Madison Avenue, Suite 1606, New York, New
York 10021, and its telephone number is (212) 319-3500.
 
COMPANY HISTORY
 
Medical Media Systems
 
     MMS, a New Hampshire general partnership, was founded to incorporate
advances in scientific visualization and computer software into products that
would help improve the practice of surgery. A wholly-owned subsidiary of Baxter
has provided MMS with approximately $7.1 million in equity financing. MMS
developed Preview and performed development work on DataFusion.
 
Ixion, Inc.
 
     Ixion, a Delaware corporation, was founded to design and develop procedural
simulators for use in training clinicians to conduct a variety of medical
procedures. Ixion's development expenses were funded, in part, by approximately
$4.5 million of contract revenues received from Ethicon Endo-Surgery
("Ethicon"), its sole customer from 1991 through 1995, in connection with the
development of a laparoscopic skills simulator, and by approximately $2.0
million received from various investors in the Bridge Financing. Ixion performed
development work on GastroSim and developed additional IVR simulation
technology.
 
The Merger
 
     The Company was incorporated in Delaware in April 1996 under the name
Medical Media Systems, Inc., and all of the partnership interests in MMS were
contributed to the Company in May 1996. Later in May 1996, Ixion was merged with
and into the Company and the Company was renamed Interact Medical Technologies
Corporation. The Company believes that the merger has brought together
outstanding management teams with significant marketing and manufacturing
expertise and development teams with complimentary skills in the areas of
software development, three-dimensional modeling and virtual reality
visualization techniques.

                                  RISK FACTORS
 
     The following risk factors should be considered carefully in addition to
the other information contained in this Prospectus before purchasing the Common
Stock offered hereby. This Prospectus contains forward-looking statements which
involve risks and uncertainties. The Company's actual results may differ
significantly from the results discussed in the forward-looking statements.
Factors that might cause such a difference include, but are not limited to,
those discussed below:
 
     Early Stage of Development.  The Company is at an early stage of
development. Only one of the Company's products is commercially available, and
limited revenues have been generated from sales since product launch in June
1996. To date the Company's resources have been dedicated to the research and
development of products based upon its expertise in digital medical imaging and
interactive software programming. The Company does not believe that certain of
its proposed products, including GastroSim and DataFusion will be commercially
viable absent significant further development and certain technological
advances, and there can be no assurance that development will be completed or
advances will be achieved. Product development involves a high degree of risk
and there can be no assurance the Company will ever finally develop, transfer to
manufacturing, or successfully commercialize, any additional products.
 
     History of Operating Losses; Uncertainty of Profitability.  The Company is
at an early stage of development, has generated little revenue to date, and has
not yet achieved profitability. Operating losses for Ixion in the years ended
December 31, 1994 and December 31, 1995 were approximately $549,000 and
$2,322,000, respectively. Operating losses for MMS in the years ended December
31, 1994 and December 31, 1995 were approximately $1,850,000 and $1,921,000,
respectively. The Company expects to continue to incur substantial losses over
at least the next several years as the Company's development, testing, marketing
and manufacturing scale-up efforts expand. To achieve profitability and
increased sales levels, the Company must, among other things, establish and
increase market acceptance of its products, respond effectively to competitive
pressures, offer high quality customer service and support, introduce on a
timely basis products incorporating its technologies and advanced versions and
enhancements to its products, and successfully market and support advanced
versions and enhancements. There can be no assurance that the Company will
complete the development of any product other than Preview, that products
developed will achieve market acceptance, or that the Company will ever produce
significant levels of revenue or achieve sustainable profitability. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     Independent Certified Public Accountants' Opinion--Going Concern.  Ixion's
financial statements for the years ended December 31, 1993, 1994 and 1995 were
audited by the Company's independent certified public accountants, whose report
includes an explanatory paragraph stating that the financial statements have
been prepared assuming the Company will continue as a going concern and that the
Company has incurred significant operating losses and has stockholders' and
working capital deficiencies that raise substantial doubt about its ability to
continue as a going concern. See "Financial Statements."
 
     Developing Markets; Uncertain Market Acceptance.  The markets for Preview
and the Company's products under development have only recently begun to
develop, are rapidly evolving and are either already characterized by, or
expected to be characterized by, an increasing number of market entrants who
will introduce or develop products competitive with the Company's products. As
is typical in the case of new and rapidly evolving industries, demand and market
acceptance for Preview and future products, if any, is subject to a high level
of uncertainty. The success of Preview and the Company's products under
development will depend, in large part, on the continued adoption, and the rate
of adoption, of MIS procedures by surgeons. The successful commercialization of
Preview (and DataFusion, if ever finalized), will depend on many other
variables, including their acceptance as reliable, accurate, cost-effective
tools for improving surgical performance and reducing time spent conducting
procedures. The successful commercialization of the Company's IVR simulators, if
ever finalized, also will depend on further variables, including market
acceptance of simulators as an alternative or supplement to traditional teaching
and training methods, such as practicing procedures on animals and cadavers and
observing and assisting trained physicians in performing procedures on live
patients. The markets in which the Company's products compete are young and have
few proven products. There can be no assurance that the markets for Preview and
the Company's products under development will develop, that Preview or the
Company's products under development will be adopted or that
 
                                        9
<PAGE>   12
 
surgeons will continue to adopt MIS procedures at a rapid pace, if at all. If
the markets for Preview or the Company's products under development fail to
develop, develop more slowly than expected or become saturated with competitors,
or if the Company's products do not achieve market acceptance, the Company's
business, results of operations and financial condition would be materially
adversely affected. See "--Technological Change," "--Competition" and
"Business--Industry Background."
 
     Uncertainty of Pricing.  The Company's current sole product, Preview, was
launched in June 1996. The Company has completed only a limited number of sales
of this product. As a result, there can be no assurance of the price at which
the Company will be able to sell or lease Preview or any of its future products.
In addition, the Company anticipates that the price of Preview and its future
products will vary depending on a variety of factors, including competitive
factors at the time future products, if any, are launched, the level of
acceptance in the marketplace, the number of new MIS procedures developed, and
the rate of adoption of new and existing MIS procedures. The Company may
discount asking prices to facilitate early market penetration or in response to
market conditions, which may reduce the Company's gross profit margins. Any
reduction in the price of Preview or any of the Company's future products or in
gross profit margins could have a material adverse effect on the Company's
business, results of operations and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
     Limited Sales, Marketing and Distribution Capability; Dependence on
Baxter.  The Company has limited experience in sales, marketing and
distribution. To market Preview or any of its future products directly, the
Company must develop a marketing and sales force with technical expertise and
with supporting distribution capability. Alternatively, the Company may obtain
the assistance of another company with a large distribution system and sales
force. There can be no assurance that the Company will be able to establish
sales and distribution capabilities or enter into profitable arrangements with
third parties with respect to marketing or distribution of its products. To the
extent the Company enters into co-promotion or other licensing arrangements, any
revenues received by the Company will be dependent on the efforts of third
parties and there can be no assurance that third party efforts will be
successful.
 
     The Company is dependent on its relationship with Baxter for a variety of
reasons, and the termination of this relationship could have a material adverse
effect on the Company. Pursuant to a distribution agreement between Baxter and
the Company, Baxter has an exclusive right to sell Preview models prepared for
use in connection with treating aortic and iliac aneurysms (except with regard
to sales to parties developing or manufacturing devices specifically designed
for endovascular treatment of aortic aneurysms for which Baxter's rights are
co-exclusive with the Company's), and is responsible for sales activities
relating to these products. Baxter is entitled to receive between 23% and 30% of
all revenue generated from its Preview sales in this field. Sales of Preview for
use in treating aortic and iliac aneurysms and the Company's financial results
will depend in significant part on the extent to which Baxter commits adequate
resources to its product launch and to the subsequent distribution of Preview.
Baxter develops, manufactures and markets a wide variety of medical devices,
some of which may compete indirectly with Preview. There can be no assurance
that Baxter will commit significant resources to market Preview for use in
treating aortic and iliac aneurysms or that its marketing activities will be
effective. See "Business--Marketing, Sales and Distribution."
 
     Limited Manufacturing Experience; Risk of Manufacturing Scale-Up.  In order
to achieve significant revenue, the Company will have to produce or arrange for
third parties to produce its products on a commercial scale. It is the Company's
current intention to produce all Preview models at the Company's FDA registered
production facility. There can be no assurance that the Company will be able to
manufacture or cause third parties to manufacture its products in commercial
scale quantities at commercially viable costs. The Company may encounter
unexpected delays or costs in scaling-up its manufacturing operations or in
hiring and training additional personnel to manufacture its products. The
failure to scale-up manufacturing successfully in a timely or cost-effective
manner, future production problems or interruptions in supply could have a
material adverse effect on the Company's business, results of operations and
financial condition. The Company will be required to adhere to applicable
regulatory requirements, including FDA-mandated current Good Manufacturing
Practices ("GMPs") regulations in the manufacture of certain of its products.
Any failure to meet such requirements could delay or prohibit the manufacturing
of the Company's products, which could have a material adverse effect on the
Company's business, results of operations and financial
 
                                       10
<PAGE>   13
 
condition. Pursuant to an agreement between Baxter and the Company, Baxter is
entitled to obtain the right to produce or to cause third parties to produce its
requirements of Preview models in the event that the Company is unable to supply
its requirements in a timely manner. If the Company were to surrender any rights
with respect to producing Preview models to Baxter, it could have a material
adverse effect on the Company's business, results of operations and financial
condition because the Company would receive only a 10% royalty on revenues
generated from Preview sales by Baxter. See "--Reliance on Single or Limited
Sources of Supply," "--Government Regulation; Uncertainty of Obtaining
Regulatory Approval" and "Business--Manufacturing."
 
     Risk of Failure to Port Preview to Windows.  The Company's success depends,
in significant part, on its ability to port its Preview models and proprietary
viewing software from the Macintosh operating system to a Windows platform,
since the installed base of Windows-based personal computers amongst the
Company's potential customers base is large and growing rapidly. The Company
believes that the failure to complete this port in a timely manner could weaken
market acceptance of Preview and ultimately have a material adverse effect on
the Company's business, results of operations and financial condition. There can
be no assurance that the Company will be able to complete this port in a timely
manner, if at all.
 
     Technological Change.  The Company's success will depend on its ability to
continually anticipate, and adapt its new and existing products to emerging
technologies and capabilities, such as improved graphic imaging and diminished
interactive lag times. The life cycles of the Company's products are difficult
to estimate because the markets that the Company targets are in the early stages
of development and because of the rapid pace of development of computer
technology. If Preview or the Company's future products, if any, become outdated
or are not accepted by the market, the Company's revenues, results of operations
and financial condition could be materially adversely affected. The markets in
which Preview and the Company's products under development will compete are
characterized by rapid technological innovation. There can be no assurance that
the Company's competitors and potential competitors will not succeed in
developing and marketing technologies and products that are more effective or
more cost effective than those developed and marketed by the Company or that
would render the Company's technology and products obsolete or noncompetitive.
The applications for which Preview and the Company's products under development
are designed can also be addressed by other products, methods or techniques,
many of which are widely accepted in the medical community. There can be no
assurance that Preview or the Company's products under development will be able
to replace such established products, methods or techniques. Additionally, new
products could be developed that replace or reduce the importance of the
Company's products. See "--Developing Markets; Uncertain Market Acceptance."
 
     Competition.  Competition in the markets in which Preview and the Company's
products under development will compete is expected to be intense. A number of
companies currently compete or intend to compete directly and indirectly with
the Company's existing product and products under development. Many of the
Company's competitors and potential competitors have substantially greater name
recognition and capital resources than the Company and also have greater
resources and expertise in the areas of research and development. See
"--Technological Change," "--Developing Markets; Uncertain Market Acceptance"
and "Business--Competition."
 
     Patents and Proprietary Technology.  The Company's success is dependent, in
part, upon its extensive proprietary technology. The Company relies on a
combination of patent, trade secret, copyright and trademark protection and
nondisclosure agreements to protect its proprietary rights. As of May 31, 1996,
the Company has one issued United States patent, U.S. Patent No. 4,907,973 for
an expert system simulator for modeling realistic internal environments and
performance, and has filed applications for certain additional United States and
foreign patents primarily related to medical imaging systems and methodology.
The Company intends to file additional patent applications in the future. There
can be no assurance that the Company will be issued any patents or that if any
patents are issued they will provide the Company with significant protection or
will not be challenged. Even if issued patents are enforceable, the Company
anticipates that any attempt to enforce its patents would be time consuming and
costly. Moreover, the laws of some foreign countries do not protect the
Company's proprietary rights in its products to the same extent as do the laws
of the United States.
 
                                       11
<PAGE>   14
 
     The Company's patent positions are uncertain and involve complex legal and
factual issues. Additionally, the coverage originally claimed in a patent
application can be significantly reduced before the patent application is
allowed and a patent is created. As a consequence, there can be no assurance
that any of the Company's patent applications will result in the issuance of
patents or, if any patents issue, that they will provide significant proprietary
protection or will not be circumvented or invalidated. Because patent
applications in the United States are maintained in secrecy until patents issue
and publication of discoveries in scientific or patent literature often lag
behind actual discoveries, the Company cannot be certain that it was the first
inventor of inventions covered by its pending patent applications or that it was
the first to file patent applications for such inventions. Moreover, the Company
may have to participate in interference proceedings declared by the United
States Patent and Trademark Office ("PTO") to determine priority of invention
which could result in substantial cost to the Company, even if the eventual
outcome is favorable to the Company. There can be no assurance that the
Company's patents if issued would be held valid by a court of competent
jurisdiction. An adverse outcome could subject the Company to significant
liabilities to third parties, require disputed rights to be licensed from or to
third parties or require the Company to cease using the technology in dispute.
 
     The Company has not been advised nor is it aware of any infringement of the
proprietary rights of others by the Company's existing product. With respect to
the Company's products under development, the Company has not been advised nor
is it aware of any proprietary rights of others which would prevent the Company
from completing and commercializing such products. There can be no assurance
that third parties will not assert infringement claims against the Company in
the future or that any such assertions will not result in costly litigation or
require the Company to obtain a license to intellectual property rights of such
parties. There can be no assurance that any such licenses would be available on
terms acceptable to the Company, if at all. Furthermore, parties making such
claims may be able to obtain injunctive or other equitable relief that could
effectively block the Company's ability to further develop or commercialize its
products in the United States and abroad and could result in the award of
substantial damages. Defense of any lawsuit or failure to obtain any such
license could have a material adverse effect on the Company. Finally,
litigation, regardless of outcome, could result in substantial cost to and a
diversion of efforts by the Company.
 
     The Company may require additional technology in the development of its
products to which the Company does not currently have rights. If the Company
determines that this additional technology is relevant to the development of its
products and further determines that a license to this additional technology is
needed, there can be no assurance that the Company can obtain a license from the
relevant party or parties on commercially reasonable terms, if at all. There can
be no assurance that the Company can obtain any license to any technology that
the Company determines it needs, on reasonable terms, if at all, or that the
Company could develop or otherwise obtain alternate technology. The failure of
the Company to obtain licenses, if needed, could have a material adverse effect
on the Company.
 
     As part of its confidentiality procedures, the Company generally enters
into nondisclosure agreements with its employees and suppliers, and limits
access to and distribution of its proprietary information. Despite these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the Company's technology without authorization. In addition, competitors
may be able to engineer around the Company's patents and trade secrets, or
reverse-engineer around its trade secrets. Accordingly, there can be no
assurance that the Company will be successful in protecting its proprietary
technology or that the Company's proprietary rights will preclude competitors
from developing products or technology equivalent or superior to that of the
Company. See "Business--Patents and Proprietary Rights."
 
     Government Regulation; Uncertainty of Obtaining Regulatory
Approval.  Preview is and DataFusion, when developed, will be subject to
government regulation in the United States and other countries. In the United
States, the Federal Food, Drug, and Cosmetic Act, as amended ("FDC Act"), and
other statutes and regulations govern the testing, manufacture, labeling,
storage, record keeping, distribution, sale, marketing, advertising and
promotion of such medical devices. Failure to comply with applicable
requirements could result in fines, recall or seizure of products, total or
partial suspension of production, withdrawal of existing product approvals or
clearances, refusal to approve or clear new applications or notices and criminal
prosecution.
 
                                       12
<PAGE>   15
 
     Prior to commercial distribution in the United States, most medical devices
must be cleared or approved by the FDA. The regulatory process is lengthy
(potentially taking up to several years), expensive and uncertain. Under the FDC
Act, medical devices are classified into one of three classes on the basis of
the controls necessary to reasonably ensure their safety and effectiveness.
Class I devices are those whose safety and effectiveness can reasonably be
ensured through general controls, such as labeling, premarket notification and
adherence to FDA-mandated current GMPs. Class II devices are those whose safety
and effectiveness can reasonably be ensured through the use of "special
controls," such as performance standards, post-market surveillance, patient
registries and FDA guidelines. Class III devices are devices that must receive
premarket approval ("PMA") from the FDA to ensure their safety and
effectiveness. They are generally life-sustaining, life-supporting, or
implantable devices, and also include most devices that were not on the market
before May 18, 1976 ("new devices") and for which the FDA has not made a finding
of substantial equivalence based upon a 510(k).
 
     Before a new device can be introduced into the market, the manufacturer
generally must obtain FDA clearance of a 510(k) or approval of a PMA
application. Following submission of a 510(k) or PMA application, the
manufacturer may not market the new device until an order is issued by the FDA
granting clearance or approval. While the Company has obtained FDA clearance
pursuant to a 510(k) to distribute Preview models of many anatomical regions,
even after FDA clearance the Company's application for clearance is subject to
continual review, and the later discovery of previously unknown problems may
result in restrictions on Preview's marketing or withdrawal of the product from
market. Withdrawal of the Company's 510(k) clearance with respect to Preview
could have a material adverse effect on the Company's business, results of
operations and financial condition.
 
     Modification or enhancement of a product that has been cleared through the
510(k) process requires clearance of a new 510(k) if the modification or
enhancement could significantly affect the safety or effectiveness of the
original device. Since 510(k) clearance was obtained for Preview, the Company
has made, and anticipates the need to make additional improvements in the device
and its labeling. The Company has not sought 510(k) clearance for any of these
improvements in the device and its labeling, and currently, on the basis of the
Company's conclusion that none of the improvements or labeling changes could
significantly affect the safety or effectiveness of the original product, does
not intend to seek such clearance. Under the FDA's regulatory scheme, the
decision whether to seek 510(k) clearance for a modified device is left first to
the manufacturer. There can be no assurance, however, that the FDA would agree
with the Company's conclusion, that the FDA would not require the Company to
cease marketing and obtain 510(k) clearance for Preview (as improved), or that
such clearance, if required, would be obtained.
 
     The Company believes that it will be necessary to file a PMA application
with respect to DataFusion. The PMA process is significantly more complex,
expensive and time consuming than the 510(k) process. The PMA process requires
the performance of at least two independent, statistically significant clinical
trials that must demonstrate the safety and effectiveness of the device in order
to obtain FDA approval of the PMA application. The PMA process typically
requires several years, and may never result in approval.
 
     The Company does not believe that its IVR simulators would be subject to
FDA review or approval or any other governmental reviews. However, in the event
the FDA or any foreign regulatory body determined to regulate such products, no
assurance can be given that compliance with such regulatory process will be
achieved or that necessary clearances will be obtained in a timely manner, if at
all.
 
     The FDC Act requires that medical devices be manufactured in accordance
with the current GMPs. These regulations require, among other things that (i)
the manufacturing process be regulated and controlled by the use of written
procedures and (ii) the ability to produce devices which meet the manufacturer's
specifications be validated by extensive and detailed testing of every aspect of
the process. They also require investigation of any deficiencies in the
manufacturing process or in the products produced and detailed record keeping.
Manufacturing facilities are therefore subject to FDA inspection on a periodic
basis to monitor compliance with current GMPs. If violations of the applicable
regulations are noted during FDA inspections of the Company's manufacturing
facilities or the manufacturing facilities of its contract manufacturers, if
any, there could be a material adverse effect on the continued marketing of the
Company's products.
 
                                       13
<PAGE>   16
 
     The FDA regulates computer software that performs the function of a
regulated device or that is intimately associated with a given device, such as
control software for imaging or other diagnostic devices. The FDA is in the
process of reevaluating its regulation of such software, and if the FDA
undertakes increased or more rigorous regulation of such software (which the
Company cannot predict), Preview and DataFusion may become subject to further
regulatory processes and clearance requirements. No assurance can be given that
compliance with more extensive regulatory processes will be achieved or that the
necessary clearances for such products will be obtained by the Company on a
timely basis, if at all. The Company may, as a result, be required to expend
additional time, resources and effort in the areas of software design,
production and quality control to ensure full technical compliance.
 
     Laws and regulations regarding the manufacture, sale and use of medical
devices are subject to change and depend heavily on administrative
interpretations. There can be no assurance that future changes in the
regulations or interpretations made by the FDA or other regulatory bodies, with
possible retroactive effect, will not adversely affect the Company.
 
     The Company plans to sell its products in several foreign markets.
Requirements pertaining to such products vary widely from country to country,
ranging from simple product registrations to detailed submissions such as those
required by the FDA. The Company believes the extent and complexity of
regulation of medical devices is increasing worldwide. The Company anticipates
this trend will continue and that the cost and time required to obtain approval
to market in any given country will greatly increase, with no assurance that
such approval will be obtained. The ability to export into other countries may
require compliance with ISO 9000 and CE Mark certifications, which are analogous
to and in some instances more rigorous than compliance with the FDA's GMPs. The
Company has not obtained any regulatory approvals to market any of its products
outside of the United States, no regulatory clearances or certifications have
yet been applied for in any country other than the United States and there is no
assurance that any such clearance or certification, if applied for, would be
issued.
 
     The Company, its existing product and future products, if any, may be
subject to a variety of laws and regulations in those states and countries where
such products are or will be marketed. These restrictions may hinder the
Company's ability to market such products in those states or countries. See
"Business--Government Regulation."
 
     Future Capital Needs; Uncertainty of Additional Funding.  The development
and commercialization of the Company's product and products under development
will require substantial funds. The Company's future capital requirements will
depend on many factors, including the time and costs involved in obtaining any
required regulatory approvals, competing technological and market developments,
the cost of manufacturing scale-up and effective commercialization activities
and arrangements, continued progress in its development programs, and the
magnitude of these programs, and the costs involved in preparing, filing,
prosecuting, maintaining and enforcing patent claims. To date, the Company has
not received significant revenues from product sales. The Company anticipates
that its existing available cash, combined with the proceeds of this Offering,
and operating revenues and interest income from cash investments will be
adequate to fund the Company for at least 18 months following this Offering. The
Company intends to seek additional funding through public or private financings.
There can be no assurance that additional financing will be available on
acceptable terms, or at all. If additional funds are raised by issuing equity
securities, further dilution to then existing stockholders may result. If
adequate funds are not available, the Company may be required to delay, scale
back or eliminate one or more of its development programs or obtain funds
through arrangements with collaborative partners or others that may require the
Company to relinquish certain rights to certain of its technologies or products
that the Company would not otherwise relinquish. See "Use of Proceeds" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
     Litigation.  From time to time the Company may be exposed to litigation
arising out of its products and operations. As of the date of this Prospectus,
the Company is not engaged in any legal proceedings that are expected,
individually or in the aggregate to have a material adverse effect on the
Company, except that an assignee of a law firm at which the Company's Secretary
formerly practiced law has initiated a lawsuit in a Washington state court for
approximately $200,000 of legal fees which are allegedly past due. The Company
 
                                       14
<PAGE>   17
 
denies owing these fees. Nonetheless, no assurance can be given that this
lawsuit will not be decided against the Company.
 
     In April 1995, Ethicon indicated in certain correspondence that it believes
it has rights beyond its exclusive license to a laparascopic skills simulator,
delivered by Ixion pursuant to a 1992 research, option and license agreement, to
source code, software, hardware, firmware and related intellectual property
incorporated in such simulator. The Company believes that there is no basis to
support this position and believes that it should prevail if litigation were
commenced. However, litigation is subject to inherent uncertainties, especially
in cases where complex technical issues are decided by a jury. Accordingly, no
assurance can be given that, if a lawsuit is commenced, it would not be decided
against the Company. Such an adverse determination could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Legal Proceedings" and "Business--Ethicon License Agreement."
 
     Dependence on and Need to Attract Key Personnel.  The success of the
Company is dependent, in part, on its ability to attract, retain and motivate
highly qualified personnel. Competition for such personnel is intense and the
inability to attract and retain additional key employees or the loss of one or
more current key employees could adversely affect the Company. There can be no
assurance that the Company will be successful in hiring or retaining requisite
personnel. Several of the Company's executive officers, including the Company's
Chief Executive Officer, have entered into employment arrangements with the
Company. See "Management--Employment Agreements" and "Certain Transactions."
 
     Management of Changing Business; Ability to Manage Growth.  As a result of
the business combination involving Ixion and MMS in connection with which the
Company obtained its assets and technologies, the Company has recently
experienced a period of significant growth. The Company expects to continue to
experience significant growth as its products are commercialized and revenue
from product sales is obtained. Such growth has placed and is expected to
continue to place a significant strain on the Company's management, information
systems and operations. As the Company grows, recruiting and retaining
additional qualified personnel to supervise and manage the Company's operations
will be important to the Company's success. The Company's potential inability to
manage its changing business effectively and to attract and retain additional
qualified management, manufacturing, engineering and development personnel could
have a material adverse effect on the Company's business, results of operations
and financial condition.
 
     Reliance on Single or Limited Sources of Supply.  The Company anticipates
that certain key components of GastroSim and DataFusion will be obtained from
single or limited sources, will be available only in limited quantities and will
require substantial production lead times. The Company's reliance on outside
vendors generally, and a single qualified source or a limited group of
suppliers, in particular, involves several risks, including a potential
inability to obtain an adequate supply of required components and reduced
control over quality, pricing and timing of delivery of components. In the past
the Company has experienced delays in the delivery of components for GastroSim
prototypes. Because the manufacture of certain of these components is
specialized and requires long lead times, there can be no assurance that delays
or shortages caused by vendors will not reoccur. The Company anticipates that a
limited number of components of the Company's products will be manufactured to
the Company's specifications by third-party manufacturers. There can be no
assurance that custom-made components from alternative third-party manufacturers
would be available on terms satisfactory to the Company, if at all. If the
Company were to change manufacturers of these components, it could experience an
interruption in supply, which could have a material adverse effect on the
Company's business, results of operations and financial condition. In addition,
the purchase of certain components by the Company is based on the Company's
internal forecasts of future product sales and there can be no assurance that
the Company's internal forecasts will be accurate or that purchases based on
forecasting will be adequate to meet the Company's requirements. See
"Business--Manufacturing."
 
     Uncertainty of Third-Party Reimbursement and Healthcare Reform
Policies.  In both domestic and foreign markets, sales of the Company's existing
product and future products, if any, will depend in part on the availability of
reimbursement by third-party payors such as government health administration
authorities, private health insurers and other organizations. Third-party payors
are increasingly challenging the price and cost-effectiveness of medical
products and services. Significant uncertainty exists as to the reimbursement
status of new healthcare products. There can be no assurance that the Company's
proposed products will be
 
                                       15
<PAGE>   18
 
considered cost-effective or that adequate third-party reimbursement will be
available to enable the Company to maintain price levels sufficient to realize
an appropriate return on its investment in product development. There can be no
assurance that reimbursement levels, once established, will not be decreased and
that any such decrease will not reduce the demand for, or the price of certain
of the Company's products. Healthcare reform measures adopted by United States
federal or state governments or by foreign governments could affect the price of
medical devices or services or the amount of reimbursement available, and
consequently, could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
     Product Liability; Availability of Insurance.  The design, development and
manufacture of the Company's existing product and future products, if any,
involve an inherent risk of product liability claims and associated adverse
publicity. Although the Company currently maintains general liability insurance,
there can be no assurance that the coverage limits of the Company's insurance
policies will be adequate. There can also be no assurance that the Company will
be able to obtain or maintain insurance for any of its commercial products. Such
insurance is expensive, difficult to obtain and may not be available in the
future on acceptable terms or at all. A successful claim brought against the
Company in excess of the Company's insurance coverage could have a material
adverse effect on the Company's business, results of operations and financial
condition.
 
     No Prior Public Market; Possible Volatility of Stock Price; No
Dividends.  Prior to this Offering, there has been no public market for the
Company's Common Stock and there can be no assurance that an active trading
market will develop or be sustained after this Offering. The initial public
offering price for the Common Stock will be determined by negotiations between
the Company and Dakin Securities Corporation (the "Representative"). See
"Underwriting." There can be no assurance that an active public market will
develop or be sustained after this Offering or that the market price of the
Common Stock will not decline below the initial public offering price. Factors
such as the announcements of technological innovations or new products by the
Company, its competitors and other third parties, as well as variations in the
Company's results of operations, market conditions, analysts' estimates and the
stock market may cause the market price of the Company's Common Stock to
fluctuate significantly. Also, future sales of shares by existing stockholders
pursuant to Rule 144 of the Securities Act of 1933, as amended (the "Securities
Act"), or through the exercise of outstanding registration rights, could have an
adverse effect on the price of the Company's Common Stock. The Company currently
intends to retain any future earnings for use in its business and does not
anticipate paying any cash dividends in the future. See "Description of Capital
Stock--Registration Rights," "Dividend Policy" and "Shares Eligible for Future
Sale."
 
     Shares Eligible for Future Sale; Registration Rights.  Sales of a
substantial number of shares of the Company's Common Stock in the public market
following this Offering could adversely affect the market price of the Common
Stock. Upon completion of this Offering, the Company will have outstanding
5,182,924 shares of Common Stock (without taking into account shares of Common
Stock issuable upon exercise of outstanding options and warrants). As of May 31,
1996, 316,173 shares of Common Stock are subject to outstanding options under
the Company's 1996 Stock Option Plan, 58,529 shares of Common Stock are subject
to outstanding non-qualified stock options, 73,162 shares of Common Stock are
subject to outstanding warrants, 683,827 additional shares are reserved for
issuance under the Company's 1996 Stock Option Plan and 200,000 shares of Common
Stock are reserved for issuance under the Company's 1996 Employee Stock Purchase
Plan. See "Management--Benefit Plans." The 2,000,000 shares of Common Stock sold
in this Offering will be freely tradeable without restrictions under the
Securities Act, except for any such shares held by an "affiliate" of the
Company, which will be subject to the "control securities" resale limitations of
Rule 144 under the Securities Act. The remaining 3,182,924 shares of Common
Stock were issued by the Company in private transactions in reliance upon one or
more exemptions under the Securities Act, are "restricted securities" as that
term is defined in Rule 144 promulgated under the Securities Act and may be sold
in compliance with such Rule, pursuant to registration under the Securities Act
or pursuant to an exemption therefrom. Of the outstanding shares, 3,182,924
shares are tradeable, subject to the limitations set forth in Rule 144 and
subject to the lock-up period described below. Stockholders owning an aggregate
of approximately 3,153,903 shares of Common Stock, representing approximately
99% of the total shares outstanding (and 273,774 shares issuable upon exercise
of outstanding warrants and options), including shares held by all officers and
directors and certain other stockholders of the Company, have agreed not to
directly or
 
                                       16
<PAGE>   19
 
indirectly offer or sell, contract to sell, grant any option to purchase, make
any short sale, transfer or otherwise dispose of or make a distribution of any
of their shares or securities convertible or exchangeable for the Company's
Common Stock for a period of 365 days (180 days in the case of shares acquired
pursuant to the Company's 1996 Employee Stock Purchase Plan) from the date of
this Prospectus without the prior written consent of the Representative. See
"Shares Eligible for Future Sale."
 
     Holders of approximately 511,308 shares of Common Stock are also entitled
to certain rights with respect to registration of such shares of Common Stock
for offer or sale to the public (without taking into account shares of Common
Stock issuable upon the exercise of outstanding options and warrants). Such
sales may have an adverse effect on the Company's ability to raise needed
capital and may adversely affect the market price of the Common Stock. See
"Shares Eligible for Future Sale" and "Description of Capital
Stock--Registration Rights."
 
     Dilution.  The initial public offering price of the Common Stock is
substantially higher than the net tangible book value per share of the Common
Stock. Investors participating in this Offering will therefore incur an
immediate, substantial dilution in net tangible book value of approximately
$6.43 per share and may incur additional dilution upon exercise of outstanding
stock options and warrants. In the event that the promissory notes issued to
investors in the Bridge Financing (the "Bridge Notes"), the $2,000,000 Note and
an additional promissory note issued by the Company to Baxter on May 24, 1996,
in the principal amount of $350,000, accruing interest at the rate of 8% per
annum (the "350,000 Note") (collectively, the "Promissory Notes"), have not been
repaid in full prior to September 1, 1996, the Company will be required to issue
2,439 shares of Common Stock for each $25,000 of principal plus accrued interest
then outstanding pursuant to the Promissory Notes. The aggregate principal
amount of the Promissory Notes outstanding as of May 31, 1996, was $4,350,000.
See "Dilution" and "Use of Proceeds."
 
     Representative's Potential Influence on the Market.  A significant number
of shares of Common Stock offered hereby may be sold to customers of the
Representative. Such customers subsequently may engage in transactions for the
sale or purchase of shares of Common Stock through or with the Representative.
Although it has no obligation to do so, the Representative intends to make a
market in the Common Stock and may otherwise affect transactions in the Common
Stock. If it participates in such market, the Representative may influence the
market, if one develops, for the Common Stock. Such market-making activity may
be discontinued at any time. Moreover, if the Representative sells the
securities issuable upon exercise of the Representative's warrants, it may be
required under the Securities Exchange Act of 1934, as amended, to temporarily
suspend its market-making activities. The prices and liquidity of the Common
Stock may be significantly affected by the degree, if any, of the
Representative's participation in such market. See "Underwriting."
 
     Payment of Debts by the Company to Baxter from Proceeds of this
Offering.  Approximately $565,000 of the proceeds of this Offering will be used
to satisfy certain debts owed by the Company to Baxter. Baxter together with a
wholly-owned subsidiary will own approximately 19.7% of the Company immediately
following this Offering. See "Use of Proceeds" and "Certain Transactions."
 
     Management Discretion Over Proceeds of this Offering.  The Company
currently has no specific plan for a significant portion of the proceeds of this
Offering. As a consequence, the Company's management will have the discretion to
allocate a large percentage of the proceeds from this Offering to uses which the
stockholders may not deem desirable, and there can be no assurance that the
proceeds can or will be invested to yield a significant return. See "Use of
Proceeds."
 
     Antitakeover Provisions.  Certain provisions of the Company's Certificate
of Incorporation and of Delaware law could discourage potential acquisition
proposals and could delay or prevent a change in control of the Company. Such
provisions could diminish the opportunities for a stockholder to participate in
tender offers, including tender offers at a price above the then current market
value of the Common Stock. Such provisions may also inhibit increases in the
market price of the Common Stock that could result from takeover attempts. In
addition, the Board of Directors, without further stockholder approval, may
issue preferred stock that could have the effect of delaying, deterring or
preventing a change in control of the Company. The issuance of preferred stock
could also adversely affect the voting power of the holders of Common Stock,
 
                                       17
<PAGE>   20
 
including the loss of voting control to others. The Company has no present plans
to issue any preferred stock. See "Description of Capital Stock--Delaware Law
and Certain Charter Provisions."
 
     Control by Existing Stockholders.  Following this Offering (assuming
exercise of all stock options and warrants beneficially owned by officers and
directors) the present executive officers and directors of the Company and their
affiliates will beneficially own approximately 25.7% of the outstanding shares
of Common Stock, and Baxter together with a wholly-owned subsidiary will
beneficially own approximately 19.7% of the outstanding shares of Common Stock.
Accordingly, the present officers and directors of the Company and their
affiliates, and Baxter will both have the ability to exercise significant
influence over the management and policies of the Company.
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered hereby are estimated to be approximately $
($          if the Underwriter's over-allotment option is exercised in full),
assuming an initial public offering price of $9.00 per share (the midpoint of
the price range set forth on the cover page of this Prospectus) and after
deducting the underwriting discounts and commissions and other estimated
offering expenses.
 
     The Company intends to use a portion of the net proceeds to repay the
outstanding balance on certain promissory notes issued to Baxter on May 24, 1996
(the "Baxter Notes") that had an outstanding balance, including accrued
interest, of $550,844 as of May 31, 1996. The Company also plans to use a
portion of the net proceeds to repay all of the Bridge Notes that had an
outstanding balance, including accrued interest, of $2,083,211 as of May 31,
1996, and that were assumed by the Company on May 24, 1996. The Baxter Notes and
the Bridge Notes bear interest at an annual rate equal to 8%.
 
     The Company also expects to use the net proceeds, including the interest
thereon, for commercialization of products, research and development, clinical
testing, capital expenditures, working capital and general corporate purposes.
In the ordinary course of its business, the Company from time to time evaluates
technologies for acquisition or license that, if acquired, could be used in the
development of product candidates. The Company has no present commitments or
agreements and is not currently involved in any negotiations with respect to
such acquisitions or licenses. The Company has not identified precisely the
amounts it plans to spend on specific development or commercialization projects
or the timing of such expenditures. The amounts actually expended for each
purpose may vary significantly depending upon numerous factors, including future
revenue growth, the amount of cash generated by the Company's operations, the
progress of the Company's development projects, the timing of regulatory
approvals, the technological advances and the status of competitive products. In
addition, expenditures will also depend upon the availability of additional
financing and other factors. The Company believes that the net proceeds from
this Offering, together with interest thereon, and the Company's existing
capital resources will satisfy its capital requirements and fund operating
losses for at least 18 months following this Offering. Pending application of
the proceeds as described above, the Company intends to invest the net proceeds
of this Offering in investment-grade, short-term securities.
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid dividends on its capital stock. The
Company currently intends to retain all earnings, if any, to fund the
development and growth of its business and therefore does not anticipate paying
any cash dividends within the foreseeable future.

discounts and commissions and other expenses of this Offering, (b) application
of a portion of the proceeds of this Offering to repay the Bridge Notes, (c) the
issuance of approximately 244,455 shares of Common Stock, assuming an initial
public offering price of $9.00 per share, immediately following the closing of
this Offering to investors in the Bridge Financing, (d) the issuance of 38,889
shares of Common Stock to Baxter, assuming an initial public offering price of
$9.00 per share, immediately following the closing of this Offering, and (e) the

accrued interest. See "Dilution" and "Certain Transactions."

                                    DILUTION
 
     The pro forma net tangible book value of the Company at March 31, 1996 was
negative ($1,987,000), or negative ($0.62) per share of Common Stock. Net pro
forma tangible book value per share of Common Stock represents the amount of the
Company's total tangible assets (pro forma total assets of $6,695,000, less
intangible assets of $3,703,000) less total liabilities of $4,979,000 divided by
the pro forma number of shares (3,182,924) of Common Stock outstanding at March
31, 1996 (which gives effect to the issuance of approximately 511,308 shares
immediately following this Offering to existing investors in connection with
rights associated with previous borrowings as more fully described elsewhere in
this Prospectus). After giving effect to the sale of the 2,000,000 shares of
Common Stock offered by the Company hereby at an assumed initial public offering
price of $9.00 per share (the midpoint of the range set forth on the cover page
of this Prospectus), and after deducting underwriter discounts and commissions
and estimated Offering expenses payable by the Company, the Company's net
tangible book value as of March 31, 1996 would have been $13,313,000 or $2.57
per share of Common Stock. This represents an immediate increase in net tangible
book value of $3.19 per share to current stockholders and an immediate dilution
of $6.43 or 71% per share to new investors purchasing Common Stock in this
Offering. The following table illustrates the per share dilution:

(2) Includes all stockholders receiving shares immediately following the closing
     of this Offering.
 
     All of the above computations assume no exercise of outstanding options or
warrants to purchase Common Stock. As of May 31, 1996, (i) options to purchase
316,173 shares of Common Stock at a weighted average exercise price of
approximately $5.18 per share under the Company's stock option plan, (ii)
options to purchase 9,755 and 48,774 shares of Common Stock pursuant to
non-qualified options at per share exercise prices of $15.38 and $0.02,
respectively, and (iii) warrants to purchase 73,162 shares of Common Stock at a
weighted average exercise price of approximately $10.65 per share (assuming an
initial public offering price of $9.00 per share (the midpoint of the range set
forth on the cover page of this Prospectus)) were outstanding. To the extent
these options and warrants become vested and are exercised, there will be
further share ownership dilution to new investors. The Company also has an
additional 683,827 shares of Common Stock reserved for issuance pursuant to the
Company's 1996 Stock Option/Stock Issuance Plan and 200,000 shares reserved for
issuance under the Company's 1996 Employee Stock Purchase Plan. Further dilution
may result from the exercise of outstanding options or options granted in the
future. See "Management--Benefit Plans."
 
     In the event that the Promissory Notes have not been repaid in full prior
to September 1, 1996, the Company will be required to issue 2,439 shares of
Common Stock for each $25,000 of principal plus accrued interest then
outstanding pursuant to the Promissory Notes. The effect of such issuances would
be further share ownership dilution to new investors. The aggregate principal
amount of the Promissory Notes outstanding as of May 31, 1996, was $4,350,000.

                            SELECTED FINANCIAL DATA
 
     The selected financial data set forth below with respect to Ixion and MMS
statements of operations for each of the three years in the period ended
December 31, 1995, and with respect to Ixion and MMS balance sheets at December
31, 1994 and 1995 are derived from audited financial statements which are
included elsewhere herein and are qualified by reference to such Financial
Statements and related Notes thereto. The Ixion Statement of Operations Data for
the years ended December 31, 1991 and 1992, and Balance Sheet Data at December
31, 1991, 1992 and 1993 have been derived from unaudited financial statements
which are not included herein. The unaudited interim financial information
includes all adjustments, consisting only of normal recurring adjustments,
considered necessary for a fair presentation of the financial position and
results of operations for these periods. Operating results for the three months
ended March 31, 1996 are not necessarily indicative of the results that may be
expected for the entire year ending December 31, 1996. The data set forth below
should be read in conjunction with Management's Discussion and Analysis of
Financial Condition and Results of Operations and the Pro Forma Condensed
Financial Information and Financial Statements and related Notes included
elsewhere in this Prospectus.
 
     Interact was formed in April 1996, and in May 1996 it acquired its assets
and technologies in connection with a business combination involving Ixion and
MMS. Inasmuch as former Ixion stockholders own the majority of the Interact
capital stock after the business combination, Ixion is considered to be the
acquiring corporation for purposes of purchase accounting and the predecessor
entity to Interact for purposes of financial reporting. When Interact financial
statements are presented as of and for periods subsequent to the business
combination, the Interact financial statements for periods prior to the business
combination will be those of what was formerly Ixion.

     As more fully described in the Pro Forma Condensed Financial Information
appearing elsewhere in this Prospectus, the Company's Unaudited Pro Forma
Balance Sheet Data at March 31, 1996, gives effect to (i) the contribution of

Interact, (ii) the issuance of Common Stock in exchange for certain accrued
amounts payable, and (iii) receipt of $2.0 million cash pursuant to a
convertible note payable to Baxter, as if such transactions had occurred as of
March 31, 1996. The Company's Unaudited Pro Forma Statements of Operations Data
for the year ended December 31, 1995 and for the three months ended March 31,
1996 include the results of operations of Ixion and MMS for the respective
periods presented and give effect to pro forma adjustments as if the
aforementioned transactions had occurred at the beginning of the respective
periods. These Pro Forma Condensed Financial Statements are not necessarily
indicative of future financial positions or results of operations of the
Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following should be read in conjunction with Selected Financial Data
and Financial Statements and related Notes thereto appearing elsewhere in this
Prospectus.
 
BACKGROUND
 
     Interact was formed in April 1996, and in May 1996, it acquired its assets
and technologies through a business combination involving Ixion and MMS.
Inasmuch as former Ixion stockholders own the majority of Interact common stock
after the business combination, Ixion is considered to be the acquiring
corporation for purposes of purchase accounting and the predecessor entity to
Interact for purposes of financial reporting. When Interact financial statements
are presented as of and for periods subsequent to the business combination, the
Interact financial statements for periods prior to the business combination will
be those of what was formerly Ixion. Accordingly, for purposes of Management's
Discussion and Analysis of Financial Condition and Results of Operations, the
period-to-period comparisons of results of operations are those of Ixion, as the
predecessor entity to Interact. Operating results comparisons relating to MMS
are also presented. Comments with respect to the Company's stage of development
and future of product development and liquidity and capital resources pertain to
Interact.
 
     Interact is at an early stage of development. Only one of the Company's
products is commercially available, and limited revenues have been generated
from product sales. To date the Company's resources have been dedicated to the
research and development of products based upon its expertise in digital medical
imaging and interactive software programming. The Company does not believe
certain of its proposed products will be commercially viable absent significant
further development and certain technological advances, and there can be no
assurance that development will be completed or advances will be achieved.
 
     The Company expects to continue to incur substantial losses over at least
the next several years as the Company's development, testing, marketing and
manufacturing scale-up efforts expand. To achieve profitability and increased
sales levels, the Company must, among other things, establish and increase
market acceptance of its products, respond effectively to competitive pressures,
offer high quality customer service and support, introduce on a timely basis
products incorporating its technologies and advanced versions and enhancements
to its products, and successfully market and support advanced versions and
enhancements. The success of the Company's products and products under
development will depend, in large part, on the continued adoption, and the rate
of adoption, of MIS procedures by surgeons. There can be no assurance that the
Company will complete the development of any product, that products developed
will achieve market acceptance, or that the Company will ever produce
significant levels of revenue or achieve sustainable profitability.
 
     The business combination involving Ixion and MMS resulted in approximately
$3.7 million of intangible assets, which will reduce future net income (or
increase net loss) as such intangible assets are amortized.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Ixion's annual financial statements were audited by the Company's
independent certified public accountants, whose report includes an explanatory
paragraph stating that the Company has incurred significant operating losses and
has stockholders' and working capital deficiencies that raise substantial doubt
about its ability to continue as a going concern. See "Financial Statements."
 
     Since 1994, Ixion has incurred operating losses which have been funded
primarily by contract revenues during 1994 and early 1995, and the Bridge
Financing since that time. Ixion had a net working capital deficit and a net
stockholders' deficit. During 1996, Ixion raised additional bridge debt funds of
$900,000, and otherwise financed its operations through the continued
forbearance of its creditors, many of whom are Company stockholders. MMS has
funded its operating losses through capital contributions and loans from its
majority owner, a wholly-owned subsidiary of Baxter.
 
     In connection with the merger of Ixion with and into Interact in May 1996,
Interact received $2.0 million cash pursuant to a short-term, convertible
promissory note payable to a principal stockholder. Interact continues to be in
the process of fund raising, including a Common Stock public offering to raise
up to
 
                                       24
<PAGE>   27
 
approximately an additional $20 million. The Company intends to use a portion of
the net proceeds of this Offering to repay approximately $2.6 million of
existing indebtedness, representing the outstanding balance on certain
promissory notes issued to stockholders. The Company also expects to use the net
proceeds for commercialization of products, research and development, clinical
testing, capital expenditures, working capital and general corporate purposes.
In the ordinary course of its business, the Company from time to time evaluates
technologies for acquisition or license that, if acquired could be used in the
development of products. The Company has no present commitments or agreements
and is not currently involved in any negotiations with respect to such
acquisitions or licenses. The Company has not identified precisely the amounts
it plans to spend on specific development or commercialization projects or the
timing of such expenditures. The amounts actually expended for each purpose may
vary significantly depending upon numerous factors, including future revenue
growth, the amount of cash generated by the Company's operations, the progress
of the Company's development projects, the timing of regulatory approvals,
technological advances and the status of competitive products. In addition,
expenditures will also depend upon the availability of additional financing and
other factors.
 
     The Company's ability to meet its anticipated future obligations and to
continue as a going concern depends upon raising sufficient capital to fund its
operations and finance its contemplated business and product development, and
achieving profitable operations. The development and commercialization of the
Company's products will require substantial funds. The Company expects to
continue to incur substantial losses over at least the next several years and
its future capital requirements will depend on many factors, including the time
and costs involved in obtaining any required regulatory approvals, the cost of
manufacturing scale-up and effective commercialization activities and
arrangements, continued progress in its development programs and the magnitude
of these programs, and the costs involved in preparing, filing, prosecuting,
maintaining and enforcing patent claims. The Company anticipates that its
existing available cash, combined with the proceeds of this Offering and
interest income from cash investments will be adequate to fund the Company for
at least 18 months following this Offering. The Company intends to seek
additional funding through public or private financings to fund its operations
thereafter. There can be no assurances that additional financing will be
available on acceptable terms, or at all. If adequate funds are not available,
the Company may be required to delay, scale back or eliminate one or more of its
development programs or to obtain funds through arrangements with collaborative
partners or others that may require the Company to relinquish certain rights to
certain of its technologies or products that the Company would not otherwise
relinquish.
 
RESULTS OF OPERATIONS
 
                                     IXION
 
THREE MONTHS ENDED MARCH 31, 1996 AND 1995
 
     The net loss for the three months ended March 31, 1996 increased $500,000
over the comparative prior year period to $909,000 as a result of elimination of
revenues and increases in both operating and interest expenses. Revenues
received during the three months ended March 31, 1995 represented final payments
from Ethicon, Ixion's sole customer, pursuant to research and license agreements
and included a minimum royalty payment. Operating expenses for the three months
ended March 31, 1996 increased approximately $76,000 or 11% due primarily to
increases in financing, legal, sales and marketing expenses, resulting from
stepped-up product and business development activities. Research and development
expenses decreased $74,000 primarily as a result of redirecting outside
consultant efforts from research and development to product and business
development. Interest expense for the three months ended March 31, 1996
increased approximately $158,000 due to increased bridge loan borrowings, which
were $325,000 at March 31, 1995 and $2.2 million at March 31, 1996. Net cash
used by operating activities for the three months ended March 31, 1996 increased
$382,000 over the comparative prior year period as a result of the increase in
net loss offset by increased non-cash charges relating primarily to original
issue discount amortization.
 
YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
     The net loss for 1995 increased over 1994 from $549,000 to $2,322,000 as a
result of decreased revenues and increased operating and interest expenses.
Revenues decreased $971,000 in 1994 to $266,000 in 1995 due to completion of
services for Ixion's sole customer. Operating expenses for 1995 increased
$679,000 or 38%
 
                                       25
<PAGE>   28
 
primarily due to increased levels of product development, marketing and
financing activities. Interest expense for the year ended December 31, 1995
increased $123,000 over the prior year due to increased bridge loan borrowings,
which were $200,000 at December 31, 1994 and $1.1 million at December 31, 1995.
Net cash used by operating activities increased to $979,000 in 1995 as compared
to $256,000 for 1994 due primarily to the decrease in revenue.
 
     Revenues of approximately $1.2 million in 1994 decreased $122,000 or 9% as
compared to 1993, due to a slightly lower level of contract services provided to
Ixion's sole customer. Operating expenses for 1994 increased $410,000, or 30%,
primarily due to Ixion incurring more costs related to research and development
and utilizing more outside consultants for business development.
 
     Deferred income taxes recorded for significant temporary differences
between tax and financial reporting basis of assets and liabilities approximate
$100,000 and $800,000 at December 31, 1994 and 1995, respectively, and primarily
relate to operating loss carryforwards. A valuation allowance has been recorded
for the full amount of deferred taxes as realization of such deferred tax asset
is not considered to be more likely than not.

                         (a development stage company)
 
THREE MONTHS ENDED MARCH 31, 1996 AND 1995
 
     There were no revenues received during the three months ended March 31,
1996 or 1995. Operating expenses for the three months ended March 31, 1996
decreased approximately $60,000 or 14% due primarily to a decrease in research
and development costs, resulting from the Company utilizing consultants to a
lesser extent than the prior year. In addition, depreciation expense decreased
in 1996 as certain equipment was fully depreciated in the comparative prior
period.
 
YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
     There were no revenues received in any of the three years ended December
31, 1995. Operating expenses for 1995 increased approximately $73,000 or 4% over
1994 primarily due to an increase in salaries expense, resulting from the hiring
of three new employees during 1995. Consulting and travel fees also increased,
due to increased business development activities. Operating expenses decreased
in 1994 as compared to 1993 by $655,000 or 26% due to a decrease in research and
development expenses resulting from the completion of a project in 1994 that had
required a higher level of expense in 1993.
 
IMPACT OF INFLATION
 
     The Company believes that the effects of inflation have not had a
significant effect on its financial condition or results of operations and
anticipates that the level of inflation, if moderate, will not have a
significant effect on operations.
 
EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
     Recently issued accounting standards having relevant applicability to the
Company consist primarily of Statement of Financial Accounting Standards No. 121
("SFAS No. 121"), which establishes accounting standards for, among other
things, the impairment of long-lived assets and certain identifiable
intangibles, and Statement of Financial Accounting Standards No. 123 ("SFAS No.
123"), which establishes standards for accounting for stock-based compensation.
SFAS No. 121 will be effective for financial statements having fiscal years
beginning after December 15, 1995, and is not expected to have a significant
effect, if any, on the Company's financial condition or results of operations.
SFAS No. 123 is not expected to have a significant effect, if any, on the
Company's financial condition or results of operations. SFAS No. 123 will be
effective for financial statements for fiscal years beginning after December 15,
1995, and required pro forma disclosures will be included in such statements. It
is expected that the Company will not adopt the "fair value based method" of
accounting for stock options, which is encouraged by SFAS No. 123, but rather
will continue to account for such, utilizing the "intrinsic value based method"
as is allowed by such statement.

                                    BUSINESS
 
     Interact develops, markets and manufactures products designed to facilitate
the effective use of minimally invasive surgical ("MIS") procedures and enhance
clinical performance. The Company's initial product, Preview(TM), was launched
in June 1996. Preview provides the clinician with a detailed three-dimensional
model of the patient-specific anatomy manufactured by processing computed
tomography ("CT") or magnetic resonance ("MR") images on the Company's
proprietary software platform at its production facility. The Company delivers
its Preview models to the clinician embodied in user-friendly proprietary
viewing software that can be run on a Macintosh personal computer. The model and
the viewing software augment traditional two-dimensional medical imaging tools
and allow the clinician to manipulate information, perform measurements and
conduct pre-surgical planning for use primarily in MIS procedures. The Company
is also currently field testing a pre-production prototype of GastroSim(TM), an
interactive virtual reality ("IVR") simulator for teaching and training
clinicians. GastroSim is designed to figuratively place the clinician inside the
upper and lower gastrointestinal tracts of a "virtual" patient and allow the
clinician to perform a number of simulated MIS procedures using realistic
medical instruments and devices. The Company is also currently developing
DataFusion, which is designed to aid the clinician during the performance of MIS
procedures by overlaying live images of a patient's anatomy on the same three-
dimensional model used in Preview, IVR simulators depicting anatomical regions
of the body other than the gastrointestinal tract and interactive CD-ROMs to
educate clinicians to perform certain procedures.
 
     In May 1996, the Company entered into a distribution agreement with Baxter
Healthcare Corporation ("Baxter"), a wholly-owned subsidiary of which is a
principal stockholder of the Company, pursuant to which Baxter obtained an
exclusive right to sell Preview for use in connection with treating aortic and
iliac aneurysms (except with regard to sales to parties developing or
manufacturing devices specifically designed for endovascular treatment of aortic
aneurysms for which Baxter's rights are co-exclusive with the Company's),
including abdominal aortic aneurysms ("AAA").
 
INDUSTRY BACKGROUND
 
     Open surgery is an invasive procedure that generally requires large
incisions and significant tissue manipulation in order to provide the clinician
with direct access to the intended surgical site. A significant part of the
trauma suffered in connection with open surgery is a result of gaining access to
the surgical site and is not caused by the surgical repair itself. For example,
the clinician often must make large incisions through layers of muscle and
tissue, which may cause muscle or nerve damage, bleeding, scarring and other
complications such as infection, temporary or permanent debilitation and pain.
As a result, many open surgical procedures require extended operating times,
expose the patient to the risks of prolonged general anesthesia and involve
lengthy hospitalization and patient recovery times. In addition, because of the
severe trauma often associated with open surgical procedures, a significant
population of patients, which includes the elderly and physically weak, are not
considered good candidates for these surgical procedures.
 
     In order to reduce the complications associated with open surgical
techniques, and driven by advances in both device technology and surgical
technique, a number of surgical approaches referred to as MIS procedures have
been developed. MIS procedures allow surgeons to access the surgical site
through the body's natural openings or by making small incisions to access body
cavities. The benefits of MIS procedures, as compared to open surgery, generally
include significantly reduced patient trauma (including muscle, nerve and other
tissue damage), complications, pain and suffering, convalescence time, procedure
time and ultimately lower medical costs.
 
     The advantages of MIS approaches over open surgical techniques suggest that
minimally invasive surgery could revolutionize the manner in which surgery is
performed. The Company believes the growth in MIS procedures is being
accelerated by today's healthcare environment, in which more cost effective
means to deliver services are aggressively being sought. The development and
adoption of MIS procedures have already had a significant impact on many
surgical fields, including general surgery, cardiology, orthopedics, gynecology,
urology and neurosurgery. Notable examples of MIS procedures that have been
widely adopted include laparoscopic and arthroscopic procedures.
 
                                       27
<PAGE>   30
 
     Despite the benefits of minimally invasive surgery, only select MIS
procedures have attained widespread adoption. In 1995, MIS procedures accounted
for approximately 15% of the surgical procedures performed in the United States.
The Company believes that its products will help address two of the major
impediments to the growth in use of MIS procedures. First, in performing MIS
procedures, parts of the physical anatomy that can be visualized and manipulated
during traditional surgeries are hidden from the eye and must be handled
remotely. In order to enable clinicians to be able to effectively perform many
MIS procedures, the Company believes that there exists a need for products which
provide clinicians with improved visualization, navigation and support
capabilities. Second, MIS procedures require proficiency in novel surgical
techniques potentially involving specialized MIS instruments and devices. Due to
the increasing number of clinically accepted procedures and the increasing
number of devices and techniques that have been developed and are expected to
continue to be developed, even highly competent clinicians may not be able to
perform all of the various techniques or utilize all of the instruments and
devices developed within their area of specialty. The Company believes that a
training and teaching system capable of assisting in development of the skills
necessary to perform an increasing number of clinically accepted surgical and
diagnostic techniques and the use of an increasing number of complex medical
instruments and devices would greatly facilitate the adoption of MIS procedures.
 
THE INTERACT SOLUTION
 
     The Company is developing products designed to facilitate the effective use
of MIS procedures and enhance clinical performance. Preview and the Company's
products under development incorporate technical advances in the fields of
medical imaging and computer software in order to provide clinicians with
information to assist in the more effective and efficient performance of MIS
procedures.
 
     Visualization and Planning.  The Company's initial product, Preview, allows
the clinician to visualize and plan surgical procedures by interacting with a
three-dimensional model of the patient-specific anatomy. MIS procedures strive
to apply precise treatment to specific anatomical locations identified in
pre-operative imaging. The Company believes that Preview's ability to generate
three-dimensional representations and present thousands more pre-operative
images than traditional imaging methods provides clinicians with a valuable
perspective for use in planning MIS procedures.
 
     As an outgrowth of Preview, the Company is also developing DataFusion, a
product designed to aid the clinician with visualization and navigation during
the performance of actual MIS procedures. DataFusion will use proprietary
software to track surgical instruments and overlay live images of a patient's
anatomy on the same three-dimensional model used in Preview. By helping the
clinician to compensate for the inability to directly visualize and manipulate
the operative area, the Company believes that Preview (and DataFusion once
developed), will improve the results of MIS procedures and enable the
application of MIS technology to additional surgical procedures.
 
     Teaching and Training.  The Company is currently field testing a
pre-production prototype of GastroSim, an IVR simulator that is designed to
create realistic clinical experiences for training clinicians to conduct
diagnostic tests and therapy on ulcers, polyps, cancers, bile stone removals,
bronchoscopies, endotracheal tube placements and ultrasound echocardial
procedures and in using sophisticated MIS instruments and devices. Although the
Company's initial market focus for its IVR simulator technology will be on
procedures typically performed in the areas of gastroenterology and family
practice medicine, the Company plans to apply its core IVR technology to develop
simulators designed to replicate MIS procedures utilized by clinicians in a
number of clinical specialties, including cardiology, cardiac surgery,
interventional radiology, urology, obstetrics/gynecology, neurosurgery and
various micro minimally invasive procedures such as functional endoscopic sinus
surgery. By allowing the clinician to replicate a multitude of complex surgical,
diagnostic and therapeutic procedures without the need for live patients,
cadavers or animals, the IVR simulators the Company intends to develop can be
anticipated to increase the number of physicians capable of performing advanced
MIS procedures, improve the general level of competency of clinicians performing
MIS procedures and help safely and expeditiously make MIS procedures more widely
available.
 
     The Company believes that Preview and its products under development, by
providing the clinician with information required in order to perform MIS
procedures and helping to ensure the competency with which
 
                                       28
<PAGE>   31
 
such procedures are performed, will offer significant clinical benefits. These
benefits include reduced trauma and limited need for general anesthesia and cost
benefits, including lower procedure costs, reduced procedure time and shorter
hospital stays, as well as faster recovery times, as compared to open surgery.
 
COMPANY STRATEGY
 
     The Company's objective is to capitalize on advances in software and
medical imaging to become a leading provider of interactive products to promote
the effective use of MIS procedures. The key elements of the Company's strategy
are as follows:
 
     -  FOCUS INITIAL PREVIEW MARKETING EFFORTS ON AAA.  In the near term the
       Company has focused its marketing efforts on the application of Preview
       to planning MIS procedures to treat AAA. After the Company has validated
       Preview for use in connection with AAA, the Company intends to
       concentrate significant resources on establishing the use of Preview as a
       standard for the performance of a number of other MIS procedures.
 
     -  COMMERCIALIZE GASTROSIM AND ESTABLISH IT AS A TEACHING AND TRAINING
       STANDARD.  The Company plans to develop and maintain relationships with
       leading medical institutions and clinicians in order to help establish
       GastroSim as a standard for use in teaching and training
       gastroenterologists and family practitioners to perform various MIS
       procedures and diagnostic and therapeutic techniques. The Company
       believes that because GastroSim is designed to be capable of providing
       unbiased and objective results of the clinician's skills performance, it
       can also be established as a standard by which medical institutions
       accredit and credential clinicians to perform certain MIS procedures and
       diagnostic and therapeutic techniques.
 
     -  EXPAND TO OTHER APPLICATIONS.  The Company believes that Preview can be
       applied in a number of procedures, including procedures for treating
       kidney stones, tumors in solid abdominal organs, prostate tumors and
       maxillofacial reconstructions. The Company's existing 510(k) clearance
       applies to its entire Preview technology and not just a specific
       application for such technology, and as such the Company believes that it
       is well positioned to model a broad variety of anatomical structures
       without significant additional United States regulatory pre-market
       clearance compliance requirements. The Company's IVR simulator
       technology, although initially applied in the Company's GastroSim
       product, is also suited to replicate MIS procedures utilized by
       clinicians in a number of clinical specialties, including, cardiology,
       cardiac surgery, interventional radiology, urology,
       obstetrics/gynecology, neurosurgery and various micro minimally invasive
       procedures such as functional endoscopic sinus surgery. The Company does
       not believe that its IVR simulators are subject to United States Food and
       Drug Administration ("FDA") regulation.
 
     -  MINIMIZE UPFRONT INVESTMENT COSTS TO CUSTOMERS.  The Company seeks to
       minimize upfront investment costs for its customers. Preview, unlike
       other three-dimensional imaging products, does not require the purchase
       of any equipment, other than imaging equipment typically available to
       clinicians and a Macintosh personal computer. Furthermore, as the
       entertainment industry continues to drive down the cost of computer
       graphic modeling and improvements are made in computer video processing,
       the Company will be able to incorporate new lower-cost hardware into its
       products under development. The Company anticipates establishing
       equipment leasing programs to lower the upfront costs required to
       purchase certain of its products under development.

PRODUCTS
 
     The Company is developing products designed to be utilized by clinicians
from the operating room to the medical school classroom. The Company's initial
product and products under development are as follows:
 
PREVIEW
 
     Preview allows the clinician to visualize and plan surgical procedures by
using a three-dimensional model of the patient-specific anatomy. Each Preview
model provides thousands of pre-operative images and a detailed
three-dimensional model of the patient-specific anatomy. The Company delivers
its Preview models to clinicians embodied in user-friendly proprietary viewing
software that can be run on a Macintosh personal computer and allows the
clinician, without significant computer expertise, to directly manipulate
information, perform measurements and conduct pre-surgical planning for use in
MIS procedures. MIS procedures strive to apply precise treatment to specific
anatomical locations identified in pre-operative imaging. The Company believes
that Preview's ability to generate three-dimensional representations and present
thousands more pre-operative images than traditional imaging methods provides
clinicians with a valuable perspective for use in planning MIS procedures.
 
     Preview augments traditional two-dimensional medical imaging. In order to
obtain a three-dimensional patient-specific model, a clinician can order a
conventional CT or MR scan and send the images to the Company's production
facility for processing. Depending on the customer's preference, images can be
transferred to the Company through the Internet, through a private data network,
or via magnetic tape and overnight shipping. At the Company's FDA registered
production facility, trained production engineers create patient specific
computer models using the Company's proprietary software and advanced graphics
workstations. The resulting models are recorded on CD-ROM and returned to the
clinician embodied in the Company's proprietary viewing software.
 
     Preview allows a clinician to address clinical planning needs without
making the sizeable investment in hardware, software and training that would be
required if a clinician were required to conduct the modeling him or herself.
Each Preview model the clinician orders currently costs between $900 and $1,500.
On an ongoing basis, Preview allows customers to outsource their
three-dimensional modeling needs and avoid service, maintenance and additional
staffing costs.
 
     It is the Company's belief that Preview will eventually supersede the use
of the angiogram in a significant number of cases. Although the angiogram
continues to be a useful imaging procedure, some of the potential advantages of
Preview over the angiogram are as follows:
 
     -  Reduced trauma and overall risk--Preview models can be generated without
       making a surgical incision and do not require anesthesia.
 
     -  Three-dimensional images--Preview provides the clinician with the
       ability to view both two and three-dimensional images.
 
     -  Improved tissue differentiation--The Company believes Preview provides
       clearer images of tissue than the angiogram.
 
     -  Reduced cost--A Preview model currently costs between $900-$1500,
       significantly less than an angiogram.
 
     Initial Application.  The Company has focused its initial marketing efforts
on the application of Preview to planning surgical procedures to treat AAA.
Disruptions of blood flow to the aorta can lead to major cardiovascular
complications and death. AAAs result from a weakening in the aortic wall which
causes a bulge or aneurysm to form. Because of the blood pressure in the aorta,
AAAs are particularly susceptible to rupture, usually resulting in death. The
National Center for Health Care Statistics estimates that approximately 1.5
million people in the United States have AAA, with approximately 190,000 new
patients diagnosed with AAA each year and approximately 45,000 AAAs repaired
each year. The cost of treating aortic and iliac aneurysms in the United States
alone is estimated to be greater than $2.0 billion per year.
 
     Until recently, the only means of repair for AAA was open surgery. Open
surgery is invasive, requires substantial incisions and long recovery times, and
can lead to complications such as blood loss and infection.
 
                                       30
<PAGE>   33
 
For example, the conventional treatment for AAA involves the opening and
division of the diaphragm, retraction of the intestines, opening of the
retroperitoneum, and clamping of the aorta above and below the aneurysm in
preparation for vascular graft insertion. This procedure typically lasts two to
four hours and is performed under general anesthesia. As a result of its
invasiveness, open surgical AAA repair has high mortality and complication rates
and is often deemed too dangerous to perform on the elderly and the weak.
 
     Preview has been used by leading surgeons in a number of countries for
planning both minimally invasive and open repair of AAA. The Company believes
that due to the drawbacks of open surgical procedures, the recommended course of
treatment for AAA will ultimately be an MIS procedure. EndoVascular
Technologies, Inc. has developed and is conducting clinical trials of an MIS
procedure for AAA and Baxter, Boston Scientific, Medtronic Inc. and Pfizer are
all believed to be in the process of developing MIS procedures and instruments
to treat AAA. The Company believes that Preview will play a particularly key
role in these MIS procedures because the importance of pre-surgical planning is
heightened by the clinician's need to size a vascular graft to use in the
procedure without first being able to observe the aneurysm.
 
     Other Applications.  Preview has been tested clinically on many parts of
the human anatomy, including the peripheral vascular system, the kidney, the
liver, the head, the neck and the breast, and in a variety of MIS procedures.
The Company believes that Preview can be applied in a number of procedures,
including procedures for treating kidney stones, tumors in solid abdominal
organs, prostate tumors and maxillofacial reconstructions. Although the Company
currently does not market Preview for use other than in connection with AAA, the
Company recently received an order to prepare a number of kidney models. The
Company's existing 510(k) clearance covers its Preview technology, not just a
specific application for such technology, and, as such, the Company believes
that it is well positioned to model a broad variety of anatomical structures
without significant additional United States regulatory pre-market clearance
compliance requirements. The Company further believes that the ability to adopt
Preview to modeling different parts of the human anatomy is limited only by
ability of CT or MR scans to capture quality images of these areas.
 
IVR SIMULATORS
 
     The Company is developing IVR simulators that consist of a platform which
is a computer system that is capable of being configured to control various
pavilions, each consisting of a specific robotic mannequin depicting one of
various anatomical regions of the body in which simulated diagnostic and
therapeutic procedures are performed. These procedures are simulated through the
use of proprietary software that monitors and actuates the pavilion and displays
video images on the platform computer monitor.
 
     The Company's initial IVR simulator, GastroSim (which is currently in the
pre-production prototype stage), consists of a pavilion depicting two anatomical
regions, the upper gastrointestinal ("UGI") and lower gastrointestinal ("LGI")
tracts. GastroSim incorporates procedures designed for (i) training medical
personnel to conduct diagnostic tests and perform therapies on ulcers, polyps,
cancers, bile stone removals and other UGI procedures, such as bronchoscopy,
endotracheal tube placement and ultrasound echocardial procedures, (ii) teaching
clinicians to manipulate sophisticated MIS medical devices and instruments and
(iii) evaluating the clinicians' ability to accomplish these diagnostic and
therapeutic maneuvers. GastroSim is currently deployed in beta test at Swedish
Medical Center in Seattle, Washington and the Company is in negotiations to
establish additional beta test sites.
 
     GastroSim displays realistic images of the UGI and LGI tracts of a
"virtual" patient on the platform computer monitor. While looking inside the
"virtual" patient, the clinician can perform a variety of diagnostic and
therapeutic procedures by inserting a flexible endoscope into the pavilion and
maneuvering the endoscope through the UGI and LGI tracts. While performing
procedures on the "virtual" patient, GastroSim replicates the feel and sound of
performing an actual procedure. GastroSim records digital data on the
clinician's performance that can be used to generate an unbiased and objective
evaluation of the clinician's therapeutic skills. Various characteristics of the
clinician's performance can be measured by GastroSim, such as "lapse time" to
perform a procedure or technique, the force used to perform such tasks and
psychomotor proficiency involved in utilizing or manipulating MIS instruments or
devices.
 
     The Company believes that GastroSim, once commercially deployed, will be a
more cost-effective means of training clinicians than performing procedures on
animals and cadavers, and will reduce the time spent by
 
                                       31
<PAGE>   34
 
trained physicians in supervising procedures. The Company also believes that by
providing the clinician with the opportunity to practice an unlimited number of
realistic procedures without the need for a live patient, GastroSim will allow
the clinician to shorten the time needed to obtain a level of proficiency
required to perform a variety of new diagnostic methods and therapies, and to
use new medical instruments and devices. The Company further believes that with
its ability to provide in-depth evaluation of the clinician's performance,
GastroSim has the potential to become a standard for accrediting, credentialing
and privileging clinicians.
 
     The initial procedure deployed by the Company for GastroSim allows the
simulator to replicate a sigmoidoscopy, the second most commonly performed
endoscopic procedure in the United States, with approximately 1.6 million such
procedures conducted in 1995 in the United States alone. The Company estimates
that there are over 100,000 clinicians, including gastroenterologists, family
practitioners, general practitioners, physicians assistants, nurses and
technicians who could benefit from using GastroSim to help master this
procedure. The Company further envisions the opportunity to model numerous
additional procedures for use with GastroSim. These procedures have the
potential to generate new sales from initial customers and will create a more
expansive product for potential additional customers. In order to capitalize on
this opportunity, the Company is currently developing a procedure to replicate a
colonoscopy, the third most commonly performed endoscopic procedure in the
United States, with approximately 1.4 million procedures conducted in 1995 in
the United States alone.
 
     While GastroSim is focused on procedures typically performed by
gastroenterologists and family practitioners, the Company is evaluating market
data, and is currently planning to develop pavilions and procedures which
replicate MIS procedures utilized by clinicians in a number of clinical
specialties, including cardiology, cardiac surgery, interventional radiology,
urology, obstetrics/gynecology, neurosurgery and various micro MIS procedures
such as functional endoscopic sinus surgery. The Company does not believe that
its IVR simulators will be subject to FDA regulation.
 
ADDITIONAL PRODUCTS UNDER DEVELOPMENT
 
  DATAFUSION
 
     As an outgrowth of Preview, the Company is developing DataFusion, a product
designed to aid the clinician with visualization and navigation during the
performance of MIS procedures. DataFusion will use proprietary software to track
surgical instruments and overlay live images of a patient's anatomy on the same
three-dimensional model used in Preview. DataFusion is being developed to
address clinical problems that hinder wider application of MIS procedures in the
operating room. These clinical problems result from the limited exposure and
visualization of anatomy possible using endoscopes and other MIS instruments and
devices.
 
     MIS procedures strive to apply precise treatment to specific anatomical
locations identified in pre-operative imaging. Unfortunately, while MIS
procedures present a great need for precision, due to the very nature of these
procedures, only a small portion of the anatomy may be visible at any time.
DataFusion is being developed to provide an exact road map of the patient's
anatomy in the form of a three-dimensional model with the location of the
surgical instruments visually superimposed. DataFusion, through computer
tracking of surgical instruments, is designed to provide the clinician with
precise targeting to specific locations defined with respect to the
three-dimensional model.
 
     DataFusion is designed to be integrated with the traditional real-time
imaging modalities (endoscopes, ultrasound, fluoroscopy, etc.) through digital
video processing and tracker interfaces. The Company anticipates that DataFusion
will use off-the-shelf computer hardware with some custom attachments to adapt
conventional surgical instrumentation for computer tracking, and that DataFusion
will be packaged on an operating room-compatible cart.
 
     DataFusion is in the prototype stage and has been used in an initial series
of animal trials to demonstrate accuracy and hardware compatibility with the
operating room environment. It is anticipated that regulatory clearance for the
DataFusion product will require extensive clinical trials to establish clinical
efficacy, and that FDA premarket approval ("PMA") will be required.
 
                                       32
<PAGE>   35
 
  CD-ROM PRODUCTS
 
     In order to address the clinicians' need for improved information and
exposure to MIS techniques and diagnostic images from a wide range of disease
states, the Company is developing a series of educational CD-ROMs for multimedia
personal computers. These products are being designed to integrate aspects of
the Company's simulation technology to create interactive illustrations of the
best-demonstrated clinical practice. The Company intends to include
sophisticated simulation modules in its CD-ROM products that are designed to
allow the clinician to become involved in performing the procedure depicted in
the CD-ROM. Using standard computer input devices, the Company currently
anticipates developing CD-ROMs that allow the clinician to manipulate MIS
instruments and devices and observe the response of the simulated tissue on the
computer monitor. The Company believes that, once they are developed, it will be
able to use its CD-ROM products as another channel to gain revenue from the
extensive database of clinical images collected in the development of IVR
simulators. The Company further believes that the CD-ROM products that it plans
to develop will appeal to both medical students and practicing clinicians as
part of their personal libraries.
 
MARKETING, SALES, AND DISTRIBUTION
 
     The Company has limited experience in sales, marketing and distribution. To
market any of its products directly, the Company must develop a marketing and
sales force with technical expertise and with supporting distribution
capability. Alternatively, the Company may obtain the assistance of another
company with a large distribution system and a large sales force. There can be
no assurance that the Company will be able to establish sales and distribution
capabilities or enter into profitable arrangements with third parties with
respect to distribution of its products. To the extent the Company enters into
co-promotion or other licensing arrangements, any revenues received by the
Company will be dependent on the efforts of third parties and there can be no
assurance that third party efforts will be successful. The Company is dependent
on its relationship with Baxter for a variety of reasons, and the termination of
this relationship could have a material adverse effect on the Company. Pursuant
to a distribution agreement between Baxter and the Company, Baxter has an
exclusive right to sell Preview for use in connection with treating aortic and
iliac aneurysms (except with regard to parties developing or manufacturing
devices specifically designed for endovascular treatment of aortic aneurysms for
which Baxter's rights are co-exclusive with the Company's), including AAA. Sales
of Preview for use in treating aortic and iliac aneurysms and the Company's
financial results will depend in significant part on the extent to which Baxter
commits adequate resources to its product launch and to the subsequent marketing
of Preview. Baxter develops, manufactures and markets a wide variety of medical
devices, some of which may compete indirectly with Preview. There can be no
assurance that Baxter will commit significant resources to market Preview for
use in treating aortic and iliac aneurysms or that its marketing activities will
be effective. See "--Baxter Distribution Agreement."
 
     The Company currently markets Preview for use in connection with AAA
through Baxter and through the Company's direct sales force. Sales of Preview
for other applications and sales of the Company's IVR simulators will be made
either through the Company's direct sales force, through distributors, by means
of collaborative arrangements, or by a combination of these methods.
 
     In connection with the Company's initial marketing efforts, the Company has
established a Medical Advisory Board comprised of vascular surgeons,
gastroenterologists, family practitioners and other prominent surgeons. The
Company also plans to sponsor training programs designed to increase clinician
familiarity with the advantages of and applications for the Company's products.
 
BAXTER DISTRIBUTION AGREEMENT
 
     In May 1996, the Company entered into a distribution agreement with Baxter,
a wholly-owned subsidiary of which is a principal stockholder of the Company,
pursuant to which Baxter has obtained an exclusive right to sell Preview for use
in connection with treating aortic and iliac aneurysms (except with regard to
parties developing or manufacturing devices specifically designed for
endovascular treatment of aortic aneurysms for which Baxter's rights are
co-exclusive with the Company's), including AAA. The Company has retained all
other rights, except as otherwise set forth below, with respect to the
marketing, sales and distribution of models generated using its Preview
technology. Under the distribution agreement, Baxter is entitled to receive
between 23% and 30% of all revenue generated from its Preview sales. Baxter is
currently developing products
 
                                       33
<PAGE>   36
 
for the less invasive treatment of aneurysms and has publicly announced plans to
include Preview in its product line.
 
     Under the terms of the distribution agreement, Baxter has a right of first
offer to negotiate distribution agreements for any future products the Company
develops in the fields of peripheral vascular surgery and/or endovascular
grafting. Baxter also has the right to cause the Company to develop, at Baxter's
sole expense, a custom product based on the Company's Preview technology for use
in treating aortic aneurysms which would be marketed, distributed and sold
exclusively by Baxter. The term of the distribution agreement is five years, and
will be automatically extended for an additional five years unless Baxter
provides written notice of termination. The parties can each terminate the
distribution agreement under certain circumstances, including the material
breach by the other party. In addition, the Company can terminate the
distribution agreement if Baxter fails to achieve certain minimum sales figures.
See "Certain Transactions."
 
     Baxter has agreed not to sell any products that are directly competitive
with the products distributed on behalf of the Company pursuant to the
distribution agreement. Baxter has also agreed to advertise and promote Preview
for use in connection with treating aortic and iliac aneurysms.
 
     The Company believes that its distribution arrangement with Baxter will
enable it to establish a presence for Preview in the market more quickly and on
a more cost-effective basis than it could achieve by approaching the market
solely with its own sales and marketing network.
 
     Pursuant to a manufacturing license agreement entered into between Baxter
and the Company in May 1996, during the term of the distribution agreement
between the parties, Baxter is entitled to obtain the right to produce or cause
third parties to produce its requirements of Preview models for use in
connection with treating aortic and iliac aneurysms in the event that the
Company is unable to supply its requirements in a timely manner. Baxter's right
to produce Preview models or have them produced will expire, in any instance
where Baxter has asserted its rights to produce Preview models, three months
after the Company notifies Baxter in writing that it can again meet its
requirements. If the Company were to surrender any rights with respect to
producing Preview models to Baxter, it could have a material adverse effect on
the Company's business, results of operations and financial condition.
 
MEDICAL ADVISORY BOARD
 
     The Company has established a Medical Advisory Board composed of clinicians
with extensive expertise in the fields related to the Company's products. The
members are available to review product plans, identify clinical applications,
and consult as needed with the Company's staff. The members of the Medical
Advisory Board are consultants to the Company and have substantial constraints
on the amount of time they can devote to Company matters. The members of the
Medical Advisory Board are as follows:

MANUFACTURING
 
     Preview is software-based and DataFusion and the Company's IVR simulators
will include both software and hardware. Relatively few of the hardware
components contained in DataFusion and the Company's IVR simulators are expected
to be unique to such products. The Company's manufacturing experience to date
has been limited to the processing of a limited number of Preview models and the
assembly of a limited number of pre-production units of GastroSim. In order to
achieve significant revenue, the Company will have to produce or arrange for
third parties to produce its products on a commercial scale. There can be no
assurance that the Company will be able to produce or cause third parties to
produce its products in commercial-scale quantities at commercially viable
costs. The Company may encounter unexpected delays or costs in scaling-up
manufacturing operations or in hiring and training additional personnel to
produce its products. The failure to scale-up manufacturing successfully in a
timely or cost-effective manner, future production problems or interruptions in
supply could have a material adverse effect on the Company's business, results
of operations and financial condition.
 
     The Company anticipates that certain key components of GastroSim and
DataFusion will be obtained from single or limited sources, will be available
only in limited quantities and will require substantial production lead times.
The Company's reliance on outside vendors generally, and a single qualified
source or a limited group of suppliers, in particular, involves several risks,
including a potential inability to obtain an adequate supply of required
components and reduced control over quality, pricing and timing of delivery of
components.
 
     The Company will be required to adhere to applicable regulatory
requirements, including FDA-mandated current Good Manufacturing Practices
("GMPs") regulations in the processing of Preview models and the eventual
manufacture of DataFusion. Any failure to meet such requirements could delay or
prohibit the manufacturing of the Company's products, which, could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
     Pursuant to an agreement between Baxter and the Company, Baxter is entitled
to obtain the right to produce, or have third parties produce, its requirements
of Preview models in the event the Company is unable to supply its requirements
in a timely manner. See "--Baxter Distribution Agreement."

PRODUCT DEVELOPMENT
 
     Ixion spent approximately $951,000, $1,189,000 and $1,332,000 on research
and development in 1993, 1994 and 1995, respectively. MMS spent approximately
$2,346,000, $1,693,000 and $1,540,000 on research and development in 1993, 1994
and 1995, respectively. The Company expects that it will continue to spend
substantial amounts on the development of products, and there can be no
assurance that any new products will be successfully developed or
commercialized. As of May 31, 1996, the Company had 12 persons engaged in
development activities.
 
COMPETITION
 
     Competition in the markets in which Preview and the Company's products
under development will compete is expected to be intense. A number of companies
currently compete or intend to compete directly and indirectly with the
Company's existing products and products under development. Many of the
Company's competitors and potential competitors have substantially greater name
recognition and capital resources than the Company and also have greater
resources and expertise in the areas of research and development.
 
     The markets in which Preview and the Company's products under development
will compete are characterized by rapid technological innovation. There can be
no assurance that the Company's competitors and potential competitors will not
succeed in developing and marketing technologies and products that are more
effective or more cost effective than those developed and marketed by the
Company or that would render the Company's technology and products obsolete or
noncompetitive. The applications for which Preview and the Company's products
under development are designed can also be addressed by other products, methods
or techniques, many of which are widely accepted in the medical community. There
can be no assurance that Preview or the Company's products under development
will be able to replace such established products, methods or techniques.
Additionally, new products could be developed that replace or reduce the
importance of the Company's products.
 
     Preview.  The Company believes that Preview competes with three-dimensional
imaging applications developed for traditional radiology workstations and
general purpose software visualization systems. Existing radiology workstations
with three-dimensional modeling capabilities include the Allegro Workstation
from ISG Technologies, Inc., Analyze software from the Mayo Clinic and CN
Software Inc., Advantage Windows from General Electric, EasyVision from
Phillips, Magic View from Siemens, and OmniPro from Algotec/Elscint. Other
companies believed to be developing products in this area include Picker, VoxL,
Cemax-Ikon and Toshiba. Suppliers of visualization software systems include AVS,
Inc., Iris Explorer, NAG, Inc., Data Explorer, KB Vision, Amerinex, Artificial
Intelligence, Inc., Interactive Data Language, Inc., VoxelView and Vital Images,
Inc. The Company believes that the primary competitive factors in the market for
three-dimensional imaging include efficacy, ease of use, quality, reliability
and cost effectiveness. In addition, the length of time required for products to
be developed and to receive regulatory approval is an important competitive
factor. The Company believes that it competes favorably with respect to these
factors, although there can be no assurance that it will continue to do so.
 
     IVR Simulators.  The Company anticipates that its IVR simulators will
compete directly against other medical procedure simulators and, to a lesser
extent, against print textbooks, interactive software, and other methods of
training for conducting surgical procedures, including performing procedures on
animals and cadavers. The Company believes that the primary competitive factors
in the market in which its IVR simulators are expected, when completed, to
compete will be cost and the ability of simulators to provide a realistic
environment in which to practice procedures. The Company believes that the
numerous years of research and development that it has performed in the area of
simulation, allows it to compete favorably with respect to these factors,
although there can be no assurance that it will continue to do so. The Company
expects that the number of competing IVR simulators will increase as the
potential benefits of medical procedure simulators become more widely
recognized. The Company is aware that each of Boston Dynamics, Cine Med and High
Techsplanations, as well as a number of universities and research institutions,
are attempting to develop technologies and products that would directly compete
with the Company's IVR simulators.
 
                                       36
<PAGE>   39
 
     CD-ROM Products.  The interactive software publishing industry is intensely
competitive. The Company's sales of the CD-ROMs that it develops, if any, may be
adversely affected by the increasing number of competitive products. The
Company's software titles are expected, when completed, to compete directly with
educational software products on various medical topics and, to a lesser extent,
with traditional print textbooks on various medical topics. There are a large
number of competitors in this market, including Engineering Animation, Inc.,
A.D.A.M. Software, Inc. and IVI Publishing, Inc. Moreover, as the market for
interactive software continues to develop, the Company expects that it will be
faced with many new competitors.
 
GOVERNMENT REGULATION
 
     Preview is and DataFusion, when developed, will be subject to government
regulation in the United States and other countries. In the United States, the
Federal Food, Drug, and Cosmetic Act, as amended ("FDC Act"), and other statutes
and regulations govern the testing, manufacture, labeling, storage, record
keeping, distribution, sale, marketing, advertising and promotion of such
medical devices. Failure to comply with applicable requirements could result in
fines, recall or seizure of products, total or partial suspension of production,
withdrawal of existing product approvals or clearances, refusal to approve or
clear new applications or notices and criminal prosecution.
 
     Prior to commercial distribution in the United States, most medical devices
must be cleared or approved by the FDA. The regulatory process is lengthy
(potentially taking up to several years), expensive and uncertain. Under the FDC
Act, medical devices are classified into one of three classes on the basis of
the controls necessary to reasonably ensure their safety and effectiveness.
Class I devices are those whose safety and effectiveness can reasonably be
ensured through general controls, such as labeling, premarket notification and
adherence to FDA-mandated current GMPs. Class II devices are those whose safety
and effectiveness can reasonably be ensured through the use of "special
controls," such as performance standards, post-market surveillance, patient
registries and FDA guidelines. Class III devices are devices that must receive
PMA from the FDA to ensure their safety and effectiveness. They are generally
life-sustaining, life-supporting, or implantable devices, and also include most
devices that were not on the market before May 18, 1976 ("new devices") and for
which the FDA has not made a finding of substantial equivalence based upon a
510(k).
 
     Before a new device can be introduced into the market, the manufacturer
generally must obtain FDA clearance of a 510(k) or approval of a PMA
application. Following submission of a 510(k) or PMA application, the
manufacturer may not market the new device until an order is issued by the FDA
granting clearance or approval. While the Company has obtained FDA clearance
pursuant to a 510(k) to distribute Preview models of many anatomical regions,
even after FDA clearance the Company's application for clearance is subject to
continual review, and the later discovery of previously unknown problems may
result in restrictions on Preview's marketing or withdrawal of the product from
market. Withdrawal of the Company's 510(k) clearance with respect to Preview
could have a material adverse effect on the Company's business, results of
operations and financial condition.
 
     Modification or enhancement of a product that has been cleared through the
510(k) process requires clearance of a new 510(k) if the modification or
enhancement could significantly affect the safety or effectiveness of the
original device. Since 510(k) clearance was obtained for Preview, the Company
has made, and anticipates the need to make additional improvements in the device
and its labeling. The Company has not sought 510(k) clearance for any of these
improvements in the device and its labeling, and currently, on the basis of the
Company's conclusion that none of the improvements or labeling changes could
significantly affect the safety or effectiveness of the original product, does
not intend to seek such clearance. Under the FDA's regulatory scheme, the
decision whether to seek 510(k) clearance for a modified device is left first to
the manufacturer. There can be no assurance, however, that the FDA would agree
with the Company's conclusion, that the FDA would not require the Company to
cease marketing and obtain 510(k) clearance for Preview (as improved), or that
such clearance, if required, would be obtained.
 
     The Company believes that it will be necessary to file a PMA application
with respect to DataFusion. The PMA process is significantly more complex,
expensive and time consuming than the 510(k) process. The PMA process requires
the performance of at least two independent, statistically significant clinical
trials that
 
                                       37
<PAGE>   40
 
must demonstrate the safety and effectiveness of the device in order to obtain
FDA approval of the PMA application. The PMA process typically requires several
years, and may never result in approval.
 
     The Company does not believe that its IVR simulators would be subject to
FDA review or approval or any other governmental reviews. However, in the event
the FDA or any foreign regulatory body determined to regulate such products, no
assurance can be given that compliance with such regulatory process will be
achieved or that necessary clearances will be obtained in a timely manner, if at
all.
 
     The FDC Act requires that medical devices be manufactured in accordance
with current GMPs. These regulations require, among other things that (i) the
manufacturing process be regulated and controlled by the use of written
procedures and (ii) the ability to produce devices which meet the manufacturer's
specifications be validated by extensive and detailed testing of every aspect of
the process. They also require investigation of any deficiencies in the
manufacturing process or in the products produced and detailed record keeping.
Manufacturing facilities are therefore subject to FDA inspection on a periodic
basis to monitor compliance with current GMPs. If violations of the applicable
regulations are noted during FDA inspections of the Company's manufacturing
facilities or the manufacturing facilities of its contract manufacturers, if
any, there could be a material adverse effect on the continued marketing of the
Company's products.
 
     The FDA regulates computer software that performs the function of a
regulated device or that is intimately associated with a given device, such as
control software for imaging or other diagnostic devices. The FDA is in the
process of re-evaluating its regulation of such software, and if the FDA
undertakes increased or more rigorous regulation of such software (which the
Company cannot predict), Preview and DataFusion may become subject to further
regulatory processes and clearance requirements. No assurance can be given that
compliance with more extensive regulatory processes will be achieved or that the
necessary clearances for such products will be obtained by the Company on a
timely basis, if at all. The Company may, as a result, be required to expend
additional time, resources and effort in the areas of software design,
production and quality control to ensure full technical compliance.
 
     Laws and regulations regarding the manufacture, sale and use of medical
devices are subject to change and depend heavily on administrative
interpretations. There can be no assurance that future changes in the
regulations or interpretations made by the FDA or other regulatory bodies, with
possible retroactive effect, will not adversely affect the Company.
 
     The Company plans to sell its products in several foreign markets.
Requirements pertaining to such products vary widely from country to country,
ranging from simple product registrations to detailed submissions such as those
required by the FDA. The Company believes the extent and complexity of
regulation of medical devices is increasing worldwide. The Company anticipates
this trend will continue and that the cost and time required to obtain approval
to market in any given country will greatly increase, with no assurance that
such approval will be obtained. The ability to export into other countries may
require compliance with ISO 9000 and CE Mark certifications, which are analogous
to and in some instances more rigorous than compliance with the FDA's GMPs. The
Company has not obtained any regulatory approvals to market any of its products
outside of the United States, no regulatory clearances or certifications have
yet been applied for in any country other than the United States and there is no
assurance that any such clearance or certification, if applied for, would be
issued.
 
     The Company, its existing product and future products, if any, may be
subject to a variety of laws and regulations in those states and countries where
such products are or will be marketed. These restrictions may hinder the
Company's ability to market such products in those states or countries.
 
PATENTS AND PROPRIETARY RIGHTS
 
     The Company's success is dependent, in part, upon its extensive proprietary
technology. The Company relies on a combination of patent, trade secret,
copyright and trademark protection and nondisclosure agreements to protect its
proprietary rights. As of May 31, 1996, the Company has one issued United States
patent, U.S. Patent No. 4,907,973 for an expert system simulator for modeling
realistic internal environments and performance, and has filed applications for
certain additional United States and foreign patents primarily related to
medical imaging systems and methodology. The Company intends to file additional
patent applications in the future. There can be no assurance that the Company
will be issued any patents or that if
 
                                       38
<PAGE>   41
 
any patents are issued they will provide the Company with significant protection
or will not be challenged. Even if issued patents are enforceable, the Company
anticipates that any attempt to enforce its patents would be time consuming and
costly. Moreover, the laws of some foreign countries do not protect the
Company's proprietary rights in its products to the same extent as do the laws
of the United States.
 
     The Company's patent positions are uncertain and involve complex legal and
factual issues. Additionally, the coverage originally claimed in a patent
application can be significantly reduced before the patent application is
allowed and a patent is created. As a consequence, there can be no assurance
that any of the Company's patent applications will result in the issuance of
patents or, if any patents issue, that they will provide significant proprietary
protection or will not be circumvented or invalidated. Because patent
applications in the United States are maintained in secrecy until patents issue
and publication of discoveries in scientific or patent literature often lag
behind actual discoveries, the Company cannot be certain that it was the first
inventor of inventions covered by its pending patent applications or that it was
the first to file patent applications for such inventions. Moreover, the Company
may have to participate in interference proceedings declared by the United
States Patent and Trademark Office ("PTO") to determine priority of invention
which could result in substantial cost to the Company, even if the eventual
outcome is favorable to the Company. There can be no assurance that the
Company's patents if issued would be held valid by a court of competent
jurisdiction. An adverse outcome could subject the Company to significant
liabilities to third parties, require disputed rights to be licensed from or to
third parties or require the Company to cease using the technology in dispute.
 
     The Company has not been advised nor is it aware of any infringement of the
proprietary rights of others by the Company's existing product. With respect to
the Company's products under development, the Company has not been advised nor
is it aware of any proprietary rights of others which would prevent the Company
from completing and commercializing such products. There can be no assurance
that third parties will not assert infringement claims against the Company in
the future or that any such assertions will not result in costly litigation or
require the Company to obtain a license to intellectual property rights of such
parties. There can be no assurance that any such licenses would be available on
terms acceptable to the Company, if at all. Furthermore, parties making such
claims may be able to obtain injunctive or other equitable relief that could
effectively block the Company's ability to further develop or commercialize its
products in the United States and abroad and could result in the award of
substantial damages. Defense of any lawsuit or failure to obtain any such
license could have a material adverse effect on the Company. Finally,
litigation, regardless of outcome, could result in substantial cost to and a
diversion of efforts by the Company.
 
     The Company may require additional technology in the development of its
products to which the Company does not currently have rights. If the Company
determines that this additional technology is relevant to the development of its
products and further determines that a license to this additional technology is
needed, there can be no assurance that the Company can obtain a license from the
relevant party or parties on commercially reasonable terms, if at all. There can
be no assurance that the Company can obtain any license to any technology that
the Company determines it needs, on reasonable terms, if at all, or that the
Company could develop or otherwise obtain alternate technology. The failure of
the Company to obtain licenses, if needed, could have a material adverse effect
on the Company.
 
     As part of its confidentiality procedures, the Company generally enters
into nondisclosure agreements with its employees and suppliers, and limits
access to and distribution of its proprietary information. Despite these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the Company's technology without authorization. In addition, competitors
may be able to engineer around the Company's patents and trade secrets, or
reverse-engineer around its trade secrets. Accordingly, there can be no
assurance that the Company will be successful in protecting its proprietary
technology or that the Company's proprietary rights will preclude competitors
from developing products or technology equivalent or superior to that of the
Company.
 
ETHICON LICENSE AGREEMENT
 
     The Company has succeeded to Ixion's rights and obligations under a 1992
research, option and license agreement ("License Agreement") between Ixion and
Ethicon Endo-Surgery ("Ethicon"), which called for
 
                                       39
<PAGE>   42
 
Ixion to design, develop and deliver a laparoscopic surgical skills simulator.
Pursuant to the License Agreement, the Company has granted Ethicon an exclusive
world-wide license to use the Company's IVR simulator technology in the field
defined in the License Agreement.
 
     Pursuant to the License Agreement, the Company is entitled to receive from
Ethicon, with respect to sales of the laparoscopic skills simulator, continuing
royalty payments of at least $50,000 per calendar quarter through the first
quarter of 1999. Ethicon has not tendered to the Company the $50,000 minimum
royalty payment for the quarter ended March 31, 1996. If Ethicon does not make
this payment to the Company it will lose its exclusivity with respect to the
laparoscopic skills simulator.
 
     In April 1995, Ethicon indicated in certain correspondence that it believes
it has rights beyond its license to the laparoscopic skills simulator delivered
pursuant to the License Agreement to source code, software, hardware, firmware
and related intellectual property incorporated in such simulator. The Company
believes that there is no basis to support this position under the terms of the
License Agreement and believes that it should prevail if litigation were
commenced. However, litigation is subject to inherent uncertainties, especially
in cases where complex technical issues are decided by a lay jury. Accordingly,
no assurance can be given that, if a lawsuit is commenced, it would not be
decided against the Company. Such an adverse determination could have a material
adverse effect upon the Company's business, results of operations and financial
condition.
 
EMPLOYEES
 
     As of May 31, 1996, the Company had 21 full-time employees and 4 part-time
employees, including 12 persons engaged in research and development, 4 persons
engaged in manufacturing and marketing, 1 person engaged in medical education
and training, and 8 persons engaged in administration, management, operations
and finance. The Company considers its relations with its employees to be good.
None of the Company's employees are represented by labor unions.
 
FACILITIES
 
     The Company's research and development facilities are located in (i)
Seattle, Washington, where it occupies approximately 4,000 square feet of
office, research and development space pursuant to two leases with unaffiliated
parties at a combined monthly rent of approximately $4,500, expiring in December
1996 and (ii) West Lebanon, New Hampshire, where it occupies approximately 3,300
square feet of office, research and development space pursuant to a lease with
an unaffiliated party at a monthly rent of approximately $3,500, expiring in
July 1997.
 
     The Company's principal executive offices are located in New York, New York
where it occupies approximately 1,000 square feet of office space at a monthly
rent of approximately $1,800, pursuant to a lease expiring in December 1997.
 
     The Company anticipates a need for larger corporate offices and
manufacturing facilities and does not expect any interruption in the operation
of its business in connection with any move to a new location.
 
LEGAL PROCEEDINGS
 
     From time to time the Company may be exposed to litigation arising out of
its products and operations. As of the date of this Prospectus, the Company is
not engaged in any legal proceedings that are expected, individually or in the
aggregate to have a material adverse effect on the Company, except that an
assignee of a law firm at which the Company's Secretary formerly practiced law
has initiated a lawsuit in a Washington state court for approximately $200,000
of legal fees which are allegedly past due. The Company denies owing these fees
and intends to vigorously defend this lawsuit. In addition, the Company and
Ethicon are in a dispute. See "--Ethicon License Agreement."

                       OPTION GRANTS IN LAST FISCAL YEAR
 
     The Company was incorporated in April 1996 and accordingly no options were
granted during fiscal 1995. In addition, neither Ixion nor MMS ever granted
options to the Named Executive Officers. However, each of the Named Executive
Officers has received the stock option grants during fiscal year 1996 (through

BENEFIT PLANS
 
  1996 STOCK OPTION/STOCK ISSUANCE PLAN
 
     The Company's 1996 Stock Option/Stock Issuance Plan (the "Plan") was
adopted by the Board of Directors on June 18, 1996 subject to approval by the
stockholders. It is expected that stockholder approval will be obtained prior to
the closing of this Offering. The Plan will become effective at the time the
Company's registration statement becomes effective. The Plan will serve as the
successor equity incentive program to Ixion's 1994 Incentive Stock Option Plan,
which has been assumed by the Company (the "Prior Plan"), and no further option
grants or stock issuances will be made under the Prior Plan following the
effective date of the Plan. All outstanding stock options and unvested share
issuances under the Prior Plan have been incorporated into the Plan but will
continue to be governed by the terms and conditions of the specific instruments
evidencing those options and issuances.
 
     A total of 1,000,000 shares of Common Stock are authorized for issuance
under the Plan including 400,000 shares available under the Prior Plan and an
additional increase of 600,000 shares. Under the Prior Plan, 316,173 shares were
reserved for issuance under options outstanding on May 31, 1996, leaving 683,827
shares available for future option grants or share issuances on such date.
Shares reserved for issuance under granted options which are not actually issued
will again become available for option grants under the terms of the Plan.
 
     The total number of shares authorized, as well as shares subject to
outstanding options, will be appropriately adjusted in the event of certain
changes to the Company's capital structure, such as stock dividends, stock
splits or other recapitalizations. The weighted average exercise price of
outstanding options under the Prior Plan, as of May 31, 1996 was approximately
$5.18.
 
     The Plan is divided into two separate programs: the option grant program
and the stock issuance program. The Plan will be administered by the Board or by
a committee of two or more Board members appointed by the Board (the "Plan
Administrator"). The Plan Administrator will have complete discretion under the
option grant program and the stock issuance program to determine which eligible
individuals are to receive option grants or stock issuances, the number of
shares subject to each such grant or issuance, the status of any granted option
as either an incentive option (which potentially qualify for certain favorable
treatment under federal tax law) or a non-statutory option, the vesting schedule
to be in effect for the option grant or stock issuance and the maximum term for
which any granted option is to remain outstanding. Participation in such
programs is limited to employees (including officers and directors) and
consultants of the Company.
 
     The exercise price for each incentive stock option must be at least 100% of
the fair market value of the stock on the date of the option grant. The exercise
price for each non-statutory option or for any share issuance under the Plan
must be at least 85% of the fair market value of the shares on the date of the
option grant or
 
                                       45
<PAGE>   48
 
stock issuance. The purchase price for any shares may be paid in cash, by
delivery of shares of Common Stock, or through a same-day sale program pursuant
to which the purchased shares will be sold immediately and a portion of the sale
proceeds applied to the payment of the purchase price. The Plan Administrator
may also permit a participant to deliver a promissory note in payment of the
purchase price and any tax liability incurred in connection with the purchase.
 
     Options granted under the option grant program may be immediately
exercisable for all the option shares, on either a vested or unvested basis, or
may become exercisable for shares in one or more installments vesting over the
participant's period of service. Shares issued under the stock issuance program
may either be fully-vested or subject to a vesting schedule tied to future
service. All unvested shares will be subject to repurchase by the Company, at
the original purchase price paid for such shares, upon the participant's
cessation of service prior to vesting in the shares. However, the Plan
Administrator will have full discretionary authority to accelerate the
exercisability of any outstanding option grant or the vesting of any issued
shares.
 
     Each option granted under the Plan will have a maximum term of ten years
and will be subject to earlier termination in the event of the optionee's
cessation of service. Incentive stock options are not assignable or transferable
by the optionee except in connection with the participant's death. Other options
are not assignable or transferable without the consent of the Plan
Administrator. The participant will have no stockholder rights with respect to
the shares subject to his or her outstanding options until such options are
exercised and the purchase price is paid for the shares. The participant will,
however, have full stockholder rights with respect to any shares issued under
the Plan.
 
     Participants subject to federal or state tax withholding in connection with
any issuance of shares under the Plan may be permitted to apply a portion of the
shares issuable upon the exercise of their outstanding options to the
satisfaction of the federal and state withholding taxes incurred in connection
with such exercise. Alternatively, such participants may be permitted to deliver
existing shares of Common Stock in satisfaction of such tax liability. In either
case, the Company will pay cash to the appropriate government authority equal to
the fair market value of the stock as a deposit of taxes withheld.
 
     Officers and directors of the Company may also be granted special stock
appreciation rights in connection with their options under which the outstanding
options can be surrendered for cancellation upon a hostile take-over of the
Company in return for a cash distribution from the Company, based on the excess
of the price per share paid by the acquiring entity in effecting the take-over
above the option exercise price. The limited stock appreciation rights may be
given to officers and directors receiving option grants. The Plan Administrator
may grant other stock appreciation rights with respect to option grants. The
other stock appreciation rights would provide the holders with the right to
receive an appreciation distribution from the Company equal to the excess of (i)
the fair market value (on the date such right is exercised) of the shares of
Common Stock in which the optionee is at the time vested under the surrendered
option over (ii) the aggregate exercise price payable for such shares. Such
appreciation distribution would be able to be made, at the Plan Administrator's
discretion, in shares of Common Stock valued at fair market value on the
exercise date, in cash or in a combination of cash and Common Stock.
 
     In the event the Company is acquired, whether by merger or asset sale, each
outstanding option which is not to be assumed by the successor corporation or
replaced with a comparable option to purchase the capital stock of the successor
corporation will automatically accelerate in full, and all unvested shares will
automatically vest, except to the extent such accelerated vesting is precluded
by the terms of the agreements evidencing those unvested shares. The Plan
Administrator can apply this acceleration to options outstanding under the Prior
Plan.
 
     The Plan provides for the automatic acceleration of outstanding options and
the vesting of unvested shares upon the following change in control events: (i)
the acquisition of more than 50% of the Company's voting stock by hostile tender
offer or (ii) a change in the composition of the Board effected through one or
more contested Board elections, except that the Plan Administrator may at the
time of a option grant or stock issuance, provide that no such acceleration
shall occur. However, no unvested options or stock issuances under the Prior
Plans will accelerate in connection with any such change in control unless the
Plan Administrator has determined to grant such acceleration.
 
                                       46
<PAGE>   49
 
     To the extent outstanding options terminate prior to exercise, the shares
subject to those options will be available for subsequent grant. In addition,
the Plan Administrator may effect cancellation/regrant programs pursuant to
which outstanding options under the option grant program (including options
incorporated from the Prior Plans) are cancelled and new options are granted for
the same or different number of option shares at an exercise price per share not
less than 85% of the fair market value of the Common Stock on the new grant
date.
 
     The Board may amend or modify the Plan at any time, and may make any such
amendment subject to stockholder approval. The Plan will terminate 10 years from
the date on which shares of the Company's Common Stock are first registered
under the Securities Exchange Act of 1934, as amended, unless sooner terminated
by the Board.
 
  1996 EMPLOYEE STOCK PURCHASE PLAN
 
     On June 18, 1996, the Board of Directors adopted, subject to stockholder
approval, the 1996 Employee Stock Purchase Plan (the "Purchase Plan") covering
an aggregate of 200,000 shares of Common Stock. It is expected that stockholder
approval will be obtained prior to the closing of this Offering. The Purchase
Plan is intended to qualify as an employee stock purchase plan within the
meaning of Section 423 of the Internal Revenue Code of 1986, as amended. Under
the Purchase Plan, eligible employees, including officers, will be entitled to
participate in periodic offerings following the commencement of the Purchase
Plan. The initial offering under the Purchase Plan will commence on the
effective date of a Registration Statement on Form S-8 covering the shares of
Common Stock issuable under the Purchase Plan (which the Company intends to file
on the effective date of this Offering), and will terminate in December 1997.
Each subsequent offering period will coincide with calendar years. The Purchase
Plan will terminate on the earlier of December 31, 2005 or the date on which all
shares available under the Purchase Plan have been purchased by the
participants.
 
     Employees are eligible to participate if they are employed by the Company
for at least 20 hours per week and at least five months per year. All employees
of the Company on the commencement date of the initial offering period can join
that period. Thereafter, only employees who have been employed by the Company
for at least three months will be allowed to participate. Employees eligible to
participate in an offering can elect to have up to 15% of their base salary
withheld under the Purchase Plan and used to purchase shares of the Common Stock
at quarterly intervals. The price of Common Stock purchased under the Purchase
Plan will be equal to 85% of the lower of the fair market value of the Common
Stock on (i) the commencement date of the offering period or (ii) the purchase
date. Persons not eligible to participate at the commencement of an offering
period may join that offering period on the first day of any quarter in which
they meet the eligibility requirements. Employees may end their participation in
the offering at any time during the offering period, except the last five days
of that period, and participation ends automatically on termination of
employment with the Company. Employees who do not join an offering period when
first permitted to do so, or who end their participation in any offering period,
may not participate again until the next offering period. Employees may alter
their level of participation on a limited basis.
 
     No participant may accrue rights to purchase more than $25,000 of stock in
any calendar year. Upon an acquisition of the Company, the outstanding payroll
deductions will be immediately applied to the purchase of Common Stock.
 
     The Purchase Plan may be terminated at any time by the Board. Unless sooner
terminated the Purchase Plan will terminate on the earlier of December 31, 2005
or the date on which all shares available under the Purchase Plan have been
issued. The Purchase Plan may be amended by the Board at any time, provided that
the Board may make any amendment of the Purchase Plan conditional on obtaining
stockholder approval.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     The Company's Bylaws provide that the Company will indemnify its directors
and executive officers and may indemnify its other officers, employees and other
agents to the fullest extent not prohibited by Delaware law. The Company is also
empowered under its Bylaws to enter into indemnification contracts with its
directors and officers and to purchase insurance on behalf of any person it is
required or permitted to
 
                                       47
<PAGE>   50
 
indemnify. Pursuant to this provision, the Company has entered into indemnity
agreements with each of its directors and executive officers.
 
     In addition, the Company's Certificate of Incorporation provides that, to
the fullest extent permitted by Delaware law, the Company's directors will not
be liable for monetary damages for breach of the directors' fiduciary duty of
care to the Company or its stockholders. This provision in the Certificate of
Incorporation does not eliminate the duty of care, and in appropriate
circumstances equitable remedies such as an injunction or other forms of
non-monetary relief would remain available under Delaware law. Each director
will continue to be subject to liability for breach of the director's duty of
loyalty to the Company or its stockholders, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
any transaction from which the director derived an improper personal benefit and
for improper distributions to stockholders. This provision also does not affect
a director's responsibilities under any other laws, such as the federal
securities laws or state or federal environmental laws.
 
     There is no pending litigation or proceeding involving a director or
officer of the Company as to which indemnification is being sought, nor is the
Company aware of any pending or threatened litigation that may result in claims
for indemnification by any director or officer.

                              CERTAIN TRANSACTIONS
 
IXION
 
     In May 1996, the Company and the following employees and consultants of
Ixion agreed to convert earned, but unpaid compensation ("Accrued Compensation")
owed to the following employees and consultants of Ixion, in the following
amounts, into Common Stock at a rate of one share for each $7.50 of Accrued
Compensation (less the requisite withholding obligations), a price determined by
the Company's Board of Directors not to be less than the estimated fair market
value of such shares at the agreement date. Bruce D. Sturman, President, Chief
Executive Officer and a director of the Company, $201,000; Valentino V.
Montegrande, Vice President, Marketing of the Company, $38,000; David Hon, a

     In April 1996, Ixion entered into an Asset Purchase Agreement ("Asset
Purchase Agreement") with David C. Hon, a director of the Company. Under such
Asset Purchase Agreement, Ixion purchased U.S. Patent No. 4,907,973, entitled
"Expert system simulator for modelling realistic internal environments and
performance" and all corresponding foreign patents and patent applications
(collectively, the "Patent") from Mr. Hon and agreed to pay Mr. Hon $25,000 on
or before August 1, 1996 and an additional $25,000 on or before August 1 of each
succeeding year for nine additional years. Pursuant to that certain Agreement
and Plan of Reorganization by and between Ixion and the Company dated May 24,
1996, the Company acquired all of Ixion's rights in the Patent. See
"Business--Patents and Proprietary Rights."
 
     Ixion entered into a consulting agreement with Xinetix in August 1995.
Harold J. Walbrink, Vice President, Manufacturing of the Company, is President
of Xinetix. Pursuant to the consulting agreement, Xinetix agreed to provide Mr.
Walbrink's consulting services to the Company in exchange for a monthly retainer
of $7,500 for April and May 1995, $12,500 for June through September 1995 and
$7,500 for October 1995 through March 1996. In addition to the above retainer,
the Company has granted Xinetix with options to purchase 48,774 shares of the
Company's Common Stock that will vest in accordance with the milestone schedule
set forth in the consulting agreement. Xinetix has three years from the date
each milestone is met to exercise the vested options. As of May 31, 1996,
options having an exercise price of $0.02 for the purchase of 9,755 shares were
fully vested.
 
     Pursuant to a consulting agreement between Ixion and Valentino V.
Montegrande, Vice President, Marketing of the Company, entered into in April
1995, the obligations under which were assumed by the Company in May 1996, Mr.
Montegrande's compensation includes a commission of 2% of the Company's revenue
derived from those sales of platforms, pavilions and procedures for the
Company's IVR simulators in which Mr. Montegrande's efforts produce sales and a
potential one time stock bonus of 14,633 shares of Common Stock based on his
performance. The term of the agreement is two years. If Mr. Montegrande's
consulting services are terminated without cause as defined in the agreement,
Mr. Montegrande is entitled to his then current compensation, including all
deferred compensation and applicable bonuses, through the end of the term of the
agreement.
 
     In May 1994, Ixion entered into a consulting agreement with Maxal. Bruce D.
Sturman, President, Chief Executive Officer and a director of the Company is
chairman of the Board of Maxal. Pursuant to the consulting agreement, Maxal
agreed to provide Mr. Sturman's services as Chief Executive Officer and Chairman
of the Board of the Company in exchange for $9,850 per month. The agreement
terminated on May 1, 1996.
 
     In each of October 1994 and October 1995, Ixion issued a two year 8%
promissory note to Bruce D. Sturman, the Company's President and Chief Executive
Officer. The aggregate principal amount of these two notes is $60,000. In May
1996, the Company assumed the obligations of Ixion under these promissory notes.
 
MMS
 
     In May 1996, the Company and Steven D. Pieper agreed to convert $20,117.39
of Accrued Compensation owed to Dr. Pieper, as an employee of MMS at a rate of
one share of Common Stock for each $7.50 of Accrued Compensation (less the
requisite withholding obligations), a price determined by the Company's
 
                                       49
<PAGE>   52
 
Board of Directors not to be less than the estimated fair value of such shares
at the agreement date. Dr. Pieper is a Vice President, Chief Technical Officer
and a director of the Company.
 
     In April 1996, MMS entered into a credit agreement with Baxter, a
wholly-owned subsidiary of which is a principal stockholder of the Company,
pursuant to which MMS issued a 6% promissory note in the principal amount of
$550,000 to Baxter payable on demand. This note was cancelled in May 1996.
 
     In October 1994, MMS entered into a regulatory services agreement with
Baxter, a wholly-owned subsidiary of which is a principal stockholder of the
Company. Under the agreement, Baxter agreed to provide regulatory professional
services to MMS for two years in exchange for $60,000 per year. MMS also agreed
to fund travel and other miscellaneous expenses pursuant to such agreement. This
agreement has since been terminated by Baxter and the Company.
 
INTERACT
 
     In May 1996, the Company issued the $350,000 Note to Baxter, a wholly-owned
subsidiary of which is a greater than 5% stockholder of the Company and entered
into the Baxter Letter. The $350,000 Note is due on the earlier of (i) the
closing of this Offering or (ii) September 1, 1996 (extendable to September 1,
1997 at the option of the Company). Pursuant to the terms of the Baxter Letter,
in addition to repayment of the principal amount of the $350,000 Note plus
accrued interest, immediately following the closing of this Offering Baxter is
entitled to receive a number of shares of Common Stock equal to $350,000 divided
by the initial public offering price of the Common Stock sold hereunder. If the
Company chooses to extend the maturity date of the $350,000 Note to September 1,
1997, Baxter will be entitled to receive 2,439 shares of Common Stock for each
$25,000 of principal outstanding under the $350,000 Note.
 
     In May 1996, the Company issued another 8% promissory note in the principal
amount of $200,000 (the "$200,000 Note") to Baxter, a wholly-owned subsidiary of
which is a greater than 5% stockholder of the Company. The $200,000 Note is due
on the earlier of (i) the closing of this Offering, or (ii) September 1, 1996.
 
     The Company entered into a Credit Agreement in May 1996 with Baxter, a
wholly-owned subsidiary of which is a greater than 5% stockholder of the
Company, pursuant to which the Company issued the $2,000,000 Note due on the
earlier of (i) the closing of this Offering or (ii) September 1, 1996
(extendable to September 1, 1997 at the option of the Company). Immediately
following the closing of this Offering, assuming this Offering closes on or
before September 1, 1996, the principal amount together with all accrued but
unpaid interest under the $2,000,000 Note automatically will be converted into
Common Stock at the initial public offering price of the Common Stock offered
hereby. If this Offering does not close on or prior to September 1, 1996 and the
Company chooses to extend the maturity date of the $2,000,000 Note to September
1, 1997, Baxter will be entitled to receive 2,439 shares of Common Stock for
each $25,000 of principal outstanding under the $2,000,000 Note.
 
     The Company entered into a Distribution Agreement in May 1996 (the
"Distribution Agreement") with Baxter, a wholly-owned subsidiary of which is a
greater than 5% stockholder of the Company, pursuant to which Baxter guaranteed
it would provide orders for at least $350,000 of the Company's Preview models
during the initial 12 month period as specified in the Distribution Agreement.
In the event the total sales by Baxter do not equal or exceed $350,000, Baxter
is obligated to pay the Company 70% of the difference between $350,000 and the
total sales for the initial 12 month period. Baxter shall receive off-set credit
for such payment against future orders. For each of the subsequent 12 month
periods during the initial five-year term of the Distribution Agreement, Baxter
guaranteed its sales would equal or exceed the product of 1,000 multiplied by
the average sales price of a Preview model during the last year. In the event
total sales do not equal or exceed that amount, Baxter is obligated to pay the
Company 70% of the shortfall. Baxter will receive off-set credit for such
payment against future orders and the Company may terminate the Distribution
Agreement. See "Business--Baxter Distribution Agreement".
 
     The Company entered into a Manufacturing License Agreement in May 1996 (the

<PAGE>   53
 
Company, effective during the term of the Distribution Agreement. Pursuant to
the Manufacturing Agreement, the Company granted Baxter an exclusive license to
use the Company's technology, if the Company fails to fill the minimum delivery
requirements under the Distribution Agreement, solely to make or have made
Preview models in connection with treating aortic and iliac aneurysms. Baxter
has agreed to pay royalties to the Company based on revenues generated from
sales of the product in the amount of 10% with the exception of the 200 clinical
training models to be provided pursuant to the Distribution Agreement for which
Baxter agreed to pay a royalty of $50 each. See "Business--Baxter Distribution
Agreement."
 
     In May 1996, the Company granted options to purchase Common Stock at $6.30
per share (the "Options") to the following individuals in the following amounts:
Bruce D. Sturman (President, Chief Executive Officer and Director of the
Company) 75,000 shares; Thomas E. Mignanelli (Vice President, Finance and Chief
Financial Officer of the Company) 50,000 shares; Steven D. Pieper (Vice
President, Chief Technical Officer and Director of the Company) 20,000 shares;
David C. Hon (Director of the Company) 20,000 shares; Leo C. McKenna (Director
of the Company) 15,000 shares; Charles E. Hutchinson (Director of the Company)
15,000 shares; James C. Caillouette (Director of the Company) 15,000 shares and
John R. Lyon (Director of the Company) 15,000 shares. With the exception of the
Options granted to Messrs. McKenna, Hutchinson, Caillouette and Lyon, whose
Options vest in equal monthly installments over 48 months of service with the
Company from the grant date, these options vest 25% upon the completion of one
year of service with the Company from the grant date and thereafter in equal
monthly installments over the next 36 months of service with the Company. Each
option has a term of 10 years and a vesting commencement date of May 27, 1996.
 
     The Company has entered into certain additional transactions with its
directors and officers (or with corporations affiliated with them), as described
under the captions, "Management--Executive Compensation" and
"Management--Employment Agreements."
 
     The Company has entered into a registration rights agreement granting
registration rights to certain individuals and entities, including Baxter, a
wholly-owned subsidiary of which is a greater than 5% stockholder of the
Company. See "Description of Capital Stock--Registration Rights."
 
     The Company believes that the foregoing transactions were in its best
interests. As a matter of policy, all future transactions between the Company
and any of its officers, directors or principal stockholders will be approved by
a majority of the independent and disinterested members of the Board of
Directors, will be on terms no less favorable to the Company than could be
obtained from unaffiliated third parties, and will be in connection with bona
fide business purposes of the Company.

                          DESCRIPTION OF CAPITAL STOCK
 
     Upon the closing of this Offering, the authorized capital stock of the
Company will consist of 10,000,000 shares of Common Stock, $0.01 par value
("Common Stock"), and 5,000,000 shares of Preferred Stock, $0.01 par value
("Preferred Stock").
 
COMMON STOCK
 
     At May 31, 1996, there were 2,671,616 shares of Common Stock outstanding
and held of record by approximately 35 stockholders. The holders of Common Stock
are entitled to one vote for each share held of record on all matters submitted
to a vote of the stockholders, except upon the closing of this Offering the
holders of Common Stock will be entitled to cumulative voting rights with
respect to the election of directors and as a consequence, certain minority
stockholders will be able to elect directors on the basis of their votes alone.
Subject to preferences that may be applicable to any shares of Preferred Stock
issued in the future, holders of Common Stock are entitled to receive ratably
such dividends as may be declared by the Board of Directors out of funds legally
available for such purpose. See "Dividend Policy." In the event of a
liquidation, dissolution or winding up of the Company, holders of the Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities and the liquidation preference of any then outstanding Preferred
Stock. Holders of Common Stock have no preemptive rights and no right to convert
their Common Stock into any other securities. There are no redemption or sinking
fund provisions applicable to the Common Stock. All outstanding shares of Common
Stock are, and shares of Common Stock to be outstanding upon completion of this
Offering will be, fully paid and nonassessable.
 
PREFERRED STOCK
 
     Effective upon the closing of this Offering, the Board of Directors has the
authority to issue up to 5,000,000 shares of the Preferred Stock in one or more
series and to fix the rights, priorities, preferences, qualifications,
limitations and restrictions, including the dividend rights, conversion rights,
voting rights, terms of redemption, terms of sinking funds, liquidation
preferences and the number of shares constituting any series and the designation
of such series, without any further vote or action by the stockholders, which
could decrease the amount of earnings and assets available for distribution to
holders of Common Stock or adversely affect the rights and powers, including
voting rights, of the holders of the Common Stock. Because the terms of the
Preferred Stock may be fixed by the Board of Directors of the Company without
stockholder action, the Preferred Stock could be issued quickly with terms
calculated to defer or delay a proposed takeover of the Company, or to make the
removal of the management of the Company more difficult.
 
     Effective upon the closing of this Offering, there will be no shares of
Preferred Stock outstanding. The Company has no present intention of issuing any
shares of Preferred Stock.
 
WARRANTS TO PURCHASE COMMON STOCK
 
     At May 31, 1996, there were outstanding warrants to purchase 48,774 shares
of Common Stock at the initial public offering price, warrants to purchase
12,194 shares of Common Stock at 150% of the initial public offering price and
warrants to purchase 12,194 shares of Common Stock at 160% of the initial public
offering price.
 
     For a description of warrants to be sold to the Representative of the
Underwriters in connection with this Offering, see "Underwriting."
 
REGISTRATION RIGHTS
 
     Pursuant to a Registration Rights Agreement dated May 24, 1996 (the
"Registration Rights Agreement"), the holders of approximately 511,308 shares of
Common Stock or their permitted transferees (the "Holders") are entitled to
certain rights with respect to the registration of such shares under the
Securities Act. Under the terms of the Registration Rights Agreement, if the
Company proposes to register any of its securities under the Securities Act for
its own account, such Holders are entitled to include shares of such
 
                                       54
<PAGE>   57
 
Common Stock therein, provided, among other conditions, that the underwriters of
any such offering have the right to limit the number of shares included in such
registration. In addition, Holders of at least 40% (or a lesser percent if the
anticipated aggregate offering price, net of underwriting discounts and
commissions, would exceed $5,000,000) of the then outstanding registrable
securities under the Registration Rights Agreement may, one year after this
Offering, require the Company to prepare and file a registration statement under
the Securities Act with respect to the shares entitled to demand registration
rights, and the Company is required to use its best efforts to effect such
registration, subject to certain conditions and limitations. The Company is not
obligated to effect more than one of these stockholder-initiated registrations,
or to effect such a registration 30 days prior to the Company's good faith
estimate of the date of a filing of or 180 days after the effective date of a
registration statement for an offering of the Company's securities, including
this Offering, nor if the shares requested to be registered may be immediately
registered on Form S-3. Holders of at least 20% of the outstanding registrable
securities under the Registration Rights Agreement may request the Company to
register such shares on Form S-3 provided the shares registered have an
aggregate market value of at least $500,000. The Company is not obligated to
effect more than two of these Form S-3 registrations in any 12 month period.
Generally, the Company is required to bear the expense of all such
registrations. The registration rights of the Holders expire: (i) three years
following the sale of securities pursuant to a registration statement filed by
the Company or (ii) when the registrable securities under the Registration
Rights Agreement may be sold in compliance with Rule 144 of the Securities Act.
The Registration Rights Agreement also provides Baxter with a one-time priority
over all other parties to such agreement to register a number of shares of the
Company's Common Stock which will result in gross proceeds of up $2,000,000 (but
not less than $1,000,000). Baxter's right to exercise such right commences six
months after this Offering and expires three years after this Offering.
 
     The Company has granted rights to register shares in certain Company
initiated registrations to the Representative of the Underwriters and to the
holders of warrants to purchase approximately 24,388 shares of the Company's
Common Stock. See "Underwriting."
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "Delaware Law"), an anti-takeover law. In general,
the statute prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
For purposes of Section 203, a "business combination" includes a merger, asset
sale or other transaction resulting in a financial benefit to the interested
stockholder, and an "interested stockholder" is a person who, together with
affiliates and associates, owns (or within three years prior, did own) 15% or
more of the corporation's voting stock.
 
     The holders of Common Stock are currently entitled to one vote for each
share held of record on all matters submitted to a vote of the stockholders
other than the election of directors, in which event any holder may demand
cumulative voting. Under cumulative voting, the holders of Common Stock are
entitled to cast for each share held the number of votes equal to the number of
directors to be elected. A holder may cast all of his or her votes for one
nominee or distribute them among any number of nominees for election.
 
     An Amended and Restated Certificate of Incorporation has been approved by
the Company's Board of Directors and stockholders, effective immediately prior
to the closing of this Offering, which, among other things, requires that any
action required or permitted to be taken by stockholders of the Company must be
effected at a duly called annual or special meeting of stockholders and may not
be effected by a consent in writing. The Company's Certificate of Incorporation,
as amended, will also require special meetings of the stockholders of the
Company be called only by the Board of Directors, the Chairman of the Board or
the Chief Executive Officer or the holders of at least 10% of the outstanding
shares of Common Stock. In addition, the Certificate of Incorporation and Bylaws
of the Company, as amended, will require that stockholders give advance notice
to the Company's secretary of any directorship nominations or other business to
be brought by stockholders at any stockholders' meeting. The Company's
Certificate of Incorporation, as amended, will also divide the Board of
Directors into two classes of directors serving staggered two-year terms, with
one class of
 
                                       55
<PAGE>   58
 
directors to be elected at each annual meeting of stockholders. The
classification of directors has the effect of making it more difficult to change
the composition of the Board. See "--Common Stock," "--Preferred Stock" and
"Risk Factors--Antitakeover Provisions." These provisions may have the effect of
deterring hostile takeovers or delaying changes in control or management of the
Company.
 
TRANSFER AGENT AND REGISTRAR
 
     American Stock Transfer is the transfer agent and registrar for the
Company's Common Stock.

<PAGE>   59
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Prior to this Offering, there has been no public market for the Common
Stock of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect prevailing market prices. Upon completion
of this Offering, the Company will have approximately 5,182,924 shares of Common
Stock outstanding, assuming no exercise of warrants and options to purchase
approximately 447,864 shares of Common Stock outstanding as of the date of this
Prospectus. Of these shares, the 2,000,000 shares sold in this Offering will be
freely tradeable without restriction or further registration under the
Securities Act, unless they are purchased by an "affiliate" of the Company as
that term is defined in Rule 144 under the Securities Act (which sales would be
subject to certain limitations and restrictions described below).
 
     The remaining 3,182,924 shares of Common Stock may be sold in the public
market only if registered or pursuant to an exemption from registration such as
Rules 144 or 144(k) promulgated under the Securities Act. Except for those
shares sold in this Offering, approximately 3,153,903 shares of the Company's
Common Stock outstanding after this Offering will be subject to contractual
lock-up agreements with the Company or the Underwriters. Specifically, each of
the Company's executive officers, directors and certain stockholders who
together hold an aggregate of 3,153,903 shares of the Company's Common Stock
have executed lock-up agreements providing that they will not offer, sell,
contract to sell, grant any option to purchase or otherwise dispose of, or agree
to dispose of any shares of Common Stock (other than as permitted in this
Offering) until 365 days (180 days in the case of shares acquired pursuant to
the Purchase Plan) after the date of this Prospectus.
 
     Taking into account these lock-up agreements and provisions, unless
registered by the Company, none of the shares outstanding prior to this Offering
will be eligible for sale prior to April 15, 1998.
 
     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 "brokers' transactions" or to market makers, within any
three-month period a number of shares that does not exceed the greater of (a)
one percent of the number of shares of Common Stock then outstanding
(approximately 51,829 shares immediately after this Offering) or (b) the average
weekly trading volume in 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 subject 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 filing provisions of
Rule 144. In addition, Rule 144A would permit the resale of restricted
securities to qualified institutional buyers, subject to compliance with
conditions of the Rule.
 
     The Company is unable to estimate the number of shares that may be sold
under Rule 144 or otherwise because this will depend on the market price for the
Common Stock of the Company, the individual circumstances of the sellers and
other factors. Future sales of shares of Common Stock, or the availability for
sale of substantial amounts of Common Stock, or the perception that such sales
could occur, could adversely affect prevailing market prices for the Common
Stock and could impair the Company's future ability to raise capital through an
offering of its equity securities.
 
     Any employee, officer or director of or consultant to the Company who
purchased his or her shares pursuant to a written compensatory plan or contract
is entitled to rely on the resale provisions of Rule 701, which permits
nonaffiliates to sell their Rule 701 shares without having to comply with the
public information, holding period, volume limitation or notice provisions of
Rule 144 and permits affiliates to sell their Rule 701 shares without having to
comply with the Rule 144 holding period restrictions.
 
     As of May 31, 1996, (i) 316,173 shares of Common Stock are subject to
outstanding options issued pursuant to the Prior Plan, (ii) 58,529 shares of
Common Stock are subject to outstanding non-qualified stock options, (iii)
73,162 shares of Common Stock are subject to outstanding warrants and 683,827
additional shares are reserved for issuance under the Plan. See
"Management--Benefit Plans." The Company intends to
 
                                       57
<PAGE>   60
 
file a registration statement under the Securities Act on Form S-8 covering an
aggregate of approximately 1,200,000 shares of Common Stock reserved for
issuance under its Plan and the Purchase Plan. Such registration statement is
expected to be filed as soon as practicable after the effectiveness of this
Offering and will automatically become effective upon filing. Accordingly,
shares registered under such registration statement will be available for resale
by nonaffiliates in the public market, subject to any vesting restrictions with
the Company or any contractual restrictions.

     The Underwriting Agreement provides that the several Underwriters are
obligated to purchase all of the 2,000,000 shares of Common Stock offered by the
Underwriters hereby (other than shares which may be purchased under the
over-allotment option), if any are purchased. The Representative has advised the
Company that the Underwriters propose to offer the shares to the public
initially at the public offering price set forth on the cover page of this
Prospectus, that the Underwriters may allow to selected dealers a concession of
$          per share and that such dealers may reallow a concession of
$          per share to certain other dealers. After this Offering, the initial
public offering price and the concessions may be changed by the Representative.
 
     The Company has granted to the Underwriters an option, expiring at the
close of business on the 30th day after the date of the Underwriting Agreement,
to purchase up to 300,000 additional shares of Common Stock at the initial
public offering price less underwriting discounts and commissions, all as set
forth on the cover page of this Prospectus. The Underwriters may exercise the
option only to cover over-allotments, if any, in the sale of shares of Common
Stock in this Offering. To the extent that the Underwriters exercise the option,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage thereof that the number of shares to
be purchased by each of them as shown in the foregoing table bears to the
2,000,000 shares of Common Stock offered hereby.
 
     The Company has agreed to pay to the Representative, individually, and not
in its capacity as the Representative, a non-accountable expense allowance of
two percent of the gross proceeds of this Offering ($360,000 if the
Underwriters' over-allotment option is not exercised and $414,000 if the
Underwriters' over-allotment option is exercised in full (assuming an initial
public offering price of $9.00 per share (the midpoint of the range set forth on
the cover page of this prospectus))), of which $50,000 has been paid to date. If
this Offering is not consummated, the Representatives will be entitled to be
reimbursed for actual out-of-pocket expenses, on an accountable basis only, up
to $50,000, inclusive of the amount paid to date. The Company has also agreed to
pay all expenses in connection with registering or qualifying the Common Stock
offered hereby for sale under the laws of the states in which the Common Stock
is sold by the Underwriters (including expenses of counsel retained for such
purposes by the Underwriters) as well as certain expenses associated with
information meetings.
 
     The Company has agreed to sell to the Representative, or its designees,
warrants (the "Underwriters' Warrants") to purchase 200,000 shares of the
Company's Common Stock at an aggregate purchase price of
 
                                       59
<PAGE>   62
 
$200. The exercise price per Underwriters' Warrant, subject to anti-dilution
adjustment, is equal to 120% of the public offering price per share of Common
Stock offered hereby. The Underwriters' Warrants expire on the fifth anniversary
of the date hereof. The Underwriters' Warrants may not be transferred or
exercised for one year from the date of this Prospectus, except for transfers to
officers of the Representative or members of the underwriting or selling group
and/or their officers or partners, if any. The Underwriters' Warrants become
exercisable during the four-year period commencing one year from the date of
this Prospectus (the "Warrant Exercise Term"). During the Warrant Exercise Term,
the holders of the Underwriters' Warrants are given, at nominal cost, the
opportunity to profit from an increase in the market price of the Company's
Common Stock. The Company has granted the Representative certain registration
rights with respect to the Underwriters' Warrants. All registration rights will
terminate seven years from the effective date of this Offering.
 
     The Company, its officers and directors and certain stockholders of the
Company have agreed that they will not, directly or indirectly, offer, sell,
offer to sell, contract to sell, grant any option to purchase or otherwise sell
or dispose of (or announce any offer, sale, offer or sale, contract of sale,
grant of any option to purchase or any other sale or disposition) any shares of
Common Stock or other capital stock of the Company or any securities convertible
into, or exercisable or exchangeable for, any shares of Common Stock or other
capital stock of the Company for a period of 365 days (180 days in the case of
shares acquired pursuant to the Purchase Plan) after the date of this Prospectus
without the prior written consent of the Representative, on behalf of the
Underwriters. See "Shares Eligible for Future Sale."
 
     Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price of the Common Stock offered hereby will
be determined through negotiations between the Company and the Representative.
Among the factors to be considered in making such determination will be the
prevailing market conditions, the Company's fiscal and operating history and
condition, the Company's prospects and the prospects of its industry, and the
market price of securities for companies in businesses similar to that of the
Company.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock offered hereby will be passed upon for the
Company by Brobeck, Phleger & Harrison LLP, San Diego, California. Certain legal
matters in connection with this Offering will be passed upon for the
Underwriters by Bronson, Bronson & McKinnon LLP, San Francisco, California.

                   INTERACT MEDICAL TECHNOLOGIES CORPORATION
 
                   PRO FORMA CONDENSED FINANCIAL INFORMATION
 
     The following unaudited pro forma condensed financial information has been
prepared in accordance with guidelines established by regulations promulgated by
the Securities and Exchange Commission. The unaudited pro forma balance sheet at
March 31, 1996, gives effect to (i) the contribution of MMS partnership
interests to a newly formed corporation and merger of Ixion with and into such
newly formed corporation, which was renamed Interact, (ii) the issuance of
Common Stock to certain employees and consultants of Ixion and MMS in exchange
for accrued amounts payable, and (iii) receipt of $2.0 million cash pursuant to
a short term, convertible promissory note payable to one of the Company's
stockholders, as if such transactions had occurred as of March 31, 1996. The
unaudited pro forma statements of operations for the year ended December 31,
1995 and for the three months ended March 31, 1996 include the results of
operations of Ixion and MMS for the respective periods presented and give effect
to the pro forma adjustments as if all such transactions had occurred at the
beginning of the respective periods.
 
     The following pro forma adjustments have been determined on the basis as
described below:
 
          1. The business combination involving MMS and Ixion is accounted for
     utilizing the purchase method of accounting. Inasmuch as the former Ixion
     stockholders own a majority of the Interact capital stock after the
     business combination, Ixion is considered to be the acquiring corporation
     for purposes of purchase accounting, and the predecessor entity to Interact
     for purposes of financial reporting. The estimated fair value attributed to
     Common Stock issued to former MMS stockholders was $5,865,000.
 
          2. Fees paid in the estimated amount of $235,000 that were directly
     attributable to the merger have been included in the purchase price
     allocated to the MMS acquisition.
 
          3. The total purchase price, including assumed liabilities at their
     estimated fair values (which approximates book value), is allocated to
     assets acquired based upon preliminary estimates of fair values. Assets
     acquired include tangible assets (which fair values are estimated to
     approximate book value) and identifiable intangible assets, such as
     products in varying stages of development. The estimated value of products
     in development which are considered to have attained technological
     feasibility, as such term is defined and interpreted in accordance with
     generally accepted accounting principles, are capitalized at their
     estimated fair values of approximately $2.5 million and are amortized over
     lives of five years. The estimated value of products in development which
     are not deemed to have attained technological feasibility, as defined, are
     capitalized in purchase accounting at their estimated fair values of
     approximately $2.5 million and immediately expensed subsequent to recording
     the business combination. The estimated value attributable to contracts and
     agreements is capitalized and amortized over five years. The total of
     estimated fair values of assets acquired reasonably approximated the total
     purchase price and accordingly, no goodwill was recorded.
 
          4. Increased amortization expense results from the purchase price
     allocation to the assets acquired and liabilities assumed in accordance
     with APB Opinion No. 16 based on preliminary estimates of fair value.
 
          5. Conversion of approximately $503,000 of accrued payables to certain
     employees and consultants for approximately 62,000 shares of Common Stock
     and payment of payroll related withholdings.
 
          6. Receipt of $2.0 million cash pursuant to issuance of a convertible
     promissory note bearing interest at prime plus 2%, and increased related
     interest expense.
 
     These pro forma condensed financial statements are not necessarily
indicative of future financial positions or results of operations of the Company
and should be read in conjunction with the financial statements of Ixion and MMS
included elsewhere in this prospectus.

(a)  To reflect pro forma increased amortization charges resulting from the
     allocation of the purchase price paid for MMS. Such amortization was based
     upon estimated remaining useful lives of five years.
 
(b)  To record proforma interest expense on convertible promissory note.
 
(c)  Calculated on the basis of approximately 3,008,000 and 3,134,000 weighted
     average shares of Common Stock for the year ended December 31, 1995 and the
     three months ended March 31, 1996, respectively. Stock options were not
     included in such computations as the effects were antidilutive.
 
(d)  In accordance with guidelines established by the Securities and Exchange
     Commission, proforma net loss does not include approximately $2.5 million
     of expense to be recorded immediately subsequent to recording the business
     combination relating to the estimated fair value of intangible assets
     acquired associated with products in development which have not been
     determined to have yet attained technological feasibility.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Ixion, Inc.
 
     We have audited the accompanying balance sheets of Ixion, Inc., (the
Company) as of December 31, 1994 and 1995 and the related statements of
operations, stockholders' equity (deficit) and cash flows for each of the three
years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements present fairly, in all material
respects, the financial position of Ixion, Inc. as of December 31, 1994 and
1995, and the results of its operations and its cash flows for each of the three
years then ended in conformity with generally accepted accounting principles.
 
     The accompanying financial statements have been prepared assuming the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has incurred operating losses and has
stockholders' and working capital deficiencies that raise substantial doubt
about the Company's ability to continue as a going concern. Management's plans
in regard to these matters are also discussed in Note 1. The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1. DESCRIPTION OF BUSINESS, MERGER, AND LIQUIDITY AND CAPITAL RESOURCES
 
     Ixion, Inc. ("Ixion" or the "Company"), is principally engaged in designing
and developing patented medical procedures training simulators for the medical
community and creating interactive, virtual reality ("IVR") medical software.
The Company has developed IVR medical software and multi-media procedures
simulators, which offer a unique and proprietary system dedicated to minimally
invasive medical training and quantitative performance evaluation primarily for
physicians. The IVR simulator consists of interrelated computer systems and
components, a life-like mannequin or body part section, and mathematical and
multi-media, interactive, virtual reality capabilities, techniques and formulas,
which are incorporated into each software program for a particular medical
procedure.
 
     OPERATIONS -- The Company, incorporated in 1983, started designing and
constructing medical procedures simulators in 1987, specifically focused on
diagnostic and therapeutic procedures. In 1992 and 1993, the Company developed
laparoscopic simulators pursuant to a contract with a large pharmaceutical
corporation and continued to provide research and development services through
1994. Since 1995, the Company has been engaged in product and business
development activities. To date the Company's resources have been dedicated to
the research and development of products based upon its expertise in digital
medical imaging and interactive software programming. The Company does not
believe that certain of its proposed products will be commercially viable absent
significant further development and certain technological advances, and there
can be no assurance that development will be completed or advances will be
achieved.
 
     MERGER -- As more fully described in Note 10 -- Subsequent Events, the
Company entered into a Merger Agreement pursuant to which, among other things,
in May 1996, the Company merged with and into a recently incorporated entity,
Interact Medical Technologies Corporation ("Interact"), which had acquired the
partnership interests of Medical Media Systems, a development stage partnership
("MMS"). Immediately prior to the merger (the "Merger") former MMS partners (the
"MMS Partners") owned all outstanding shares of Interact common stock ("Interact
Stock"). Effective upon merger, Ixion common stock converted into .48774 shares
of Interact Stock, and Interact received $2.0 million cash from one of the MMS
Partners in exchange for a short-term promissory note, which is convertible,
under certain circumstances, at Interact's option into Interact Stock. Other
outstanding warrants, options or other commitments to issue Ixion common stock
also are provided with similar rights to acquire Interact Stock. This business
combination will be accounted for utilizing purchase accounting. Inasmuch as
Ixion stockholders own the majority of Interact capital stock after the merger,
Ixion is considered to be the acquiring corporation for purposes of purchase
accounting and the predecessor entity to Interact for purposes of financial
reporting.
 
     LIQUIDITY AND CAPITAL RESOURCES -- Since 1994, the Company has incurred
operating losses which have been funded primarily by contract revenues during
1994 and early 1995, and bridge debt financing since then. The Company has had,
and continues to have, a net working capital deficit and net stockholders'
deficit that raise substantial doubt about the Company's ability to continue as
a going concern. Subsequent to December 31, 1995, the Company has raised
additional bridge debt funds of $900,000, and otherwise financed its operations
through the continued forbearance of its creditors, many of whom are Company
stockholders.
 
     In connection with the Merger, Interact received $2.0 million cash pursuant
to a short-term, convertible promissory note payable to a stockholder. Interact
continues to be in the process of fund raising, including a common stock public
offering to raise up to an additional $20.0 million. The Company intends to use
a portion of the net proceeds of such offering to repay approximately $2.6
million of existing indebtedness, representing the outstanding balance on
certain promissory notes issued to stockholders. The Company also expects to use
the net proceeds for commercialization of products, research and development,
clinical testing, capital expenditures, working capital and general corporate
purposes. The amounts actually expended for each purpose may vary significantly
depending upon numerous factors, including future revenue growth, the amount of
cash generated by the Company's operations, the progress of the Company's
development projects,

NOTE 1. DESCRIPTION OF BUSINESS, MERGER, AND LIQUIDITY AND CAPITAL RESOURCES
(CONTINUED)
availability of sufficient funding for such expenditures, the timing of
regulatory approvals, technological advances and the status of competitive
products.
 
     The Company expects to continue to incur substantial losses over at least
the next several years as the Company's development, testing, marketing and
manufacturing scale-up efforts expand. To achieve profitability and increased
sales levels, the Company must, among other things, establish and increase
market acceptance of its products, respond effectively to competitive pressures,
offer high quality customer service and support, introduce on a timely basis
products incorporating its technologies and advanced versions and enhancements
to its products, and successfully market and support advanced versions and
enhancements. There can be no assurance that the Company will complete the
development of any product, or that products developed will achieve market
acceptance, or that the Company will ever produce significant levels of revenue
or achieve sustainable profitability.
 
     The Company's ability to meets its anticipated future obligations and
continue as a going concern depends upon raising sufficient capital to fund its
operations and finance its contemplated business expansion, and achieving
profitable operations. The development and commercialization of the Company's
products will require substantial funds. The Company's future capital
requirements will depend on many factors, including the time and costs involved
in obtaining any required regulatory approvals, competing technological and
market developments, the cost of manufacturing scale-up and effective
commercialization activities and arrangements, continued progress in its
development programs and the magnitude of those programs and the costs involved
in preparing, filing, prosecuting, maintaining and enforcing patent claims. The
Company intends to seek additional funding through public or private financings.
There can be no assurance that additional financing will be available on
acceptable terms or at all. If adequate funds are not available, the Company may
be required to delay, scale back or eliminate one or more of its development
programs or obtain funds through arrangements with collaborative partners or
others that may require the Company to relinquish certain rights to certain of
its technologies or products that the Company would not otherwise relinquish.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     INTERIM FINANCIAL STATEMENTS -- The interim financial data as of and for
the three months ended March 31, 1995 and 1996 is unaudited; however, in the
opinion of Company management, the interim data includes all adjustments,
consisting only of normal recurring adjustments necessary for a fair statement
of results for the interim periods. The 1996 interim period results of
operations are not necessarily indicative of results for the entire year.
 
     USE OF ESTIMATES -- The Company's financial statements are prepared in
conformity with generally accepted accounting principles which 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 revenue and
expenses during the reporting period. Actual results could differ from the
estimates.
 
     CASH AND CASH EQUIVALENTS -- Cash and cash equivalents are comprised
primarily of funds on deposit with banks.
 
     EQUIPMENT AND SOFTWARE -- Equipment and software is recorded at cost less
accumulated depreciation based on assets' estimated useful lives of five years.
Depreciation is computed using primarily straight-line methods. Maintenance and
repairs are expensed while major improvements are capitalized.
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS -- Accrued payables and advances due to
stockholders are due on demand. Due to the related party nature and uncertainty
of the timing of actual repayment, the Company cannot estimate the fair value of
such financial instruments. The carrying value of notes payable represents the

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
face value of such notes less unamortized original issue discount. The recording
of original issue discount for the estimated fair value of the Company's stock
issued together with the notes payable results in an approximation of fair value
of such notes.
 
     INCOME TAXES -- Income taxes are accounted for utilizing the liability
method. Deferred income taxes are provided to represent the tax consequence on
future years for temporary differences between tax and financial reporting basis
of assets and liabilities. A valuation allowance has been provided for the total
amount of deferred tax assets which would otherwise be recorded for income tax
benefits, primarily relating to operating loss carryforwards, as realization is
not more likely than not.
 
     REVENUE RECOGNITION -- The Company records revenue as contract services or
deliverables are provided and records fees for royalty payments, which, to date
represent minimum royalties, as revenue upon receipt.
 
     COMMON STOCK AND STOCK SPLIT -- The Company records issuances of its common
stock and grants or issuances of options or warrants to acquire such stock at
the amount of cash received or, if issued for other than cash consideration, at
the estimated fair value of such security at the date of issuance or grant. To
the extent that options are issued or granted with an exercise price less than
the estimated fair value of common stock at the date of grant ("compensatory"
options), the Company records an increase in amounts ascribed to common stock
and expense for such difference.
 
     On December 31, 1993, the Company effected a split of its common stock. All
share and per share information presented in these financial statements give
effect to the stock split.
 
     NET LOSS PER SHARE -- Net loss per share is computed by dividing net loss
by the weighted average number of shares outstanding. Stock options did not
impact loss per share as the effect was antidilutive. Pursuant to Securities and
Exchange Commission Staff Accounting Bulletin No. 83, common stock issued for
consideration below the expected offering price during the twelve-month period
preceding an initial public offering, together with common stock options and
warrants issued during such period with exercise prices below the expected
offering price, have been included in the calculation of common shares utilizing
the treasury stock method as if they were outstanding for all periods presented.
The weighted average number of shares of common stock outstanding for the
calculation of net loss per share approximated 1,239,000, 2,655,000 and
2,850,000 for the years ended December 31, 1993, 1994 and 1995, respectively,
and (unaudited) 2,802,000 and 2,953,000 for the three months ended March 31,
1995 and 1996, respectively.
 
     EFFECT OF RECENTLY ISSUED ACCOUNTING STANDARDS -- Recently issued
accounting standards having relevant applicability to the Company consist
primarily of Statement of Financial Accounting Standards No. 121 ("SFAS No.
121"), which establishes accounting standards for, among other things, the
impairment of long-lived assets and certain identifiable intangibles, and SFAS
No. 123 ("SFAS No. 123"), which establishes standards for accounting for
stock-based compensation. SFAS No. 121 and SFAS No. 123 are effective for fiscal
years beginning after December 15, 1995. SFAS No. 121 is not expected to have a
significant effect, if any, in the Company's financial condition or results of
operations. It is not expected that the Company will adopt the "fair value based
method" of accounting for stock options, which is encouraged by SFAS No. 123,
but rather will continue to account for such, utilizing the "intrinsic value
based method" as is allowed by that statement.
 
NOTE 3. MAJOR CUSTOMER AND CONTRACT REVENUES
 
     During 1993, 1994 and 1995, the Company received revenues from a customer
pursuant to terms of research and license agreements. During 1995 revenues
included a minimum royalty payment for one of the Company's products. Under
certain circumstances, the licensee could obtain exclusive rights for the sale
and

     The promissory notes (the "Notes") are unsecured and bear interest at an
annual rate of 8%. In connection with Note borrowings, holders of such Notes are
entitled to receive that number of shares of the Company's common stock which
have a value equal to the face amount of the Notes. As set forth in the offering
memorandum pursuant to which the Notes were issued, for each $25,000 of Notes,
the holder is entitled to receive 2,500 shares, subject to adjustment, of common
stock upon the Company's initial public offering, on the basis of such offering
price at $10 per share. In the event the initial offering price is more than $10
per share, the Note holder would receive fewer shares, and conversely, if the
price is less than $10 per share, the Note holder would receive more shares. The
Company has recorded the estimated fair value of shares issuable as an increase
in common stock and as original issue discount. Original issue discount is
amortized on a straight line basis over the life of related debt.
 
     The Notes may be extended, at the Company's option until September 1, 1997,
in such event the Company shall issue to the holder of such Notes shares of the
Company's common stock at the rate of 5,000 shares for each $25,000 principal
amount of Notes extended.
 
     Additionally, during 1995, the Company borrowed and repaid $100,000 under
terms of a 90-day unsecured 8% promissory note.
 
     Average borrowings outstanding during 1994 and 1995 approximated $67,000
and $578,000, respectively.
 
     Subsequent to March 31, 1996, the Company repaid $200,000 of Notes.

     During 1994 and 1995, the Company issued common stock to certain
consultants in consideration for, among other things, marketing, strategic
planning, legal and other financial related services. During 1994 and 1995, the
Company recorded expense of approximately $14,000 and $321,000, respectively,
relating to such issuances of stock, which are recorded at the approximate fair
value of securities issued.
 
     Some of the Company's consulting agreements provide for future issuances
and vesting of Company common stock and options to acquire Company common stock
under certain circumstances. Approximately 45,000 shares in 1996 and 30,000
shares in 1997 are issuable and vest dependent upon continued service, and
30,000 shares are issuable and vest in each of the Company's first 2 years of
systems sales dependent upon the consultant and the Company attaining certain
revenue levels. Stock options for 100,000 shares, which are to be exercisable
for three years at per share prices to be determined by the Company's Board of
Directors, are

NOTE 5. COMMON STOCK AND STOCK OPTIONS (CONTINUED)
issuable and vest dependent upon the consultant and the Company attaining
certain milestones; during 1995, 20,000 of such options were granted with an
exercise price of $0.01 per share.
 
     The Company has an Incentive Stock Option Plan (the "Plan") which permits
grants to Company employees of options to acquire shares of Common Stock.
Pursuant to Plan terms, the exercise price of stock options shall not be less
than the fair market value of Common Stock at the date of grant. The duration
and terms of options shall be established by the Board of Directors. The Company
has reserved 400,000 shares of common stock for Plan grants. During 1993 and
1994, the Company granted approximately 195,000 and 41,000 Plan options,
respectively. During 1995, approximately 105,000 Plan options were cancelled and
approximately 6,000 Plan options were exercised. All granted Plan options have a
10 year term and vest over three years on a straight-line, monthly basis
commencing six months after certain conditions have been met. All such
conditions have been met for options granted. Plan options are canceled at the
time grantees leave the Company's employ, except to the extent that 5% of
originally granted options may be exercised by such grantees for a certain
period.
 
     In addition, subsequent to December 31, 1995, in connection with certain
financing transactions, the Company issued options and warrants to acquire
common stock. In January 1996, the Company issued 100,000 warrants having an
exercise price at the Company's initial public offering price ("$IPO")
exercisable for five years. In April 1996, the Company issued 20,000 options
having an exercise price of $7.50 per share exercisable for 18 months, and
50,000 warrants having exercise prices of 150% to 160% of the $IPO exercisable
for three years following the Company's initial public offering.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 6. RELATED PARTY TRANSACTIONS
 
     The Company has received cash advances from its principal stockholders.
Borrowings are unsecured, have no stated due date and bear interest at an annual
rate of 8%. At December 31, 1994 and 1995, advances payable approximate $45,000
and $95,000, respectively. Average borrowings were $15,000 and $53,000 during
1994 and 1995, respectively.
 
     The Company has accrued payables due to its principal stockholders and
other Company officers and directors, which primarily represent amounts due
pursuant to terms of consulting agreements. These payables are due on demand and
do not bear interest. See Note 10 -- Subsequent Events regarding conversion of
such accrued payables to common stock.
 
     Prior to 1996, the Company annually acquired from a principal stockholder,
exclusive license rights for certain patents. Included in research and
development expense is $50,000 in each of 1993, 1994 and 1995, representing cash
payments made during each such year and including approximately $29,000 which
was accrued at December 31, 1995 relating to that year. In April 1996, the
Company acquired these patent rights pursuant to terms of an agreement in
exchange for, among other things, $25,000 annual payments to be made by the
Company to such stockholder during 1996 through 2005. The discounted present
value of payments, net of accrued liabilities which were canceled, approximates
$130,000, and will be included in research and development expense. These rights
are limited as to transferability and assignability and are subject to reversion
under certain conditions.
 
NOTE 7. INCOME TAXES
 
     Deferred income taxes recorded for significant temporary differences
between tax and financial reporting basis of assets and liabilities approximate
$100,000 and $800,000 at December 31, 1994 and 1995, respectively, and primarily
relate to operating loss carryforwards. A valuation allowance has been recorded
for the full amount of deferred taxes as realization of such deferred tax asset
is not considered to be more likely than not.
 
     For income tax purposes, at December 31, 1995, the Company has net
operating loss carryforwards approximating $2.0 million, which begin to expire
in 2006. As a result of changes in the Company's stock ownership, utilization of
net operating loss carryforwards could be subject to annual limitations. The
annual amount that could be utilized is limited to the value of the Company as
of the date of the change in ownership multiplied by the interest rate on
federal long-term exempt securities at that date.

NOTE 8. FACILITIES, EQUIPMENT AND SOFTWARE (CONTINUED)
     The Company leases its office and development facilities and certain office
equipment under short-term operating leases. Rent expense approximated $87,000,
$94,000 and $127,000 during 1993, 1994 and 1995, respectively.
 
NOTE 9. COMMITMENTS
 
     Pursuant to terms of a June 1995 agreement, the Company may, under certain
events and circumstances and subject to such consummation of such a defined
event, be obligated to pay a fee to a financial consultant. Such events, as more
specifically defined in the agreement, generally would include certain business
combinations or alliances. The fee is variable in amount and is payable in cash
and in warrants to purchase Company common stock. See Note 10 -- Subsequent
Events regarding final settlement of obligations pursuant to this agreement.
 
NOTE 10. SUBSEQUENT EVENTS
 
     Effective May 24, 1996, the Company entered into a Merger Agreement
pursuant to which, among other things, Ixion merged with and into Interact which
had acquired the MMS partnership interests. As a result of the Merger, former
Ixion stockholders own the majority of the Interact capital stock.
 
     The business combination involving MMS and Ixion is accounted for utilizing
the purchase method of accounting. Inasmuch as the former Ixion stockholders own
a majority of the Interact capital stock after the business combination, Ixion
is considered the acquiring corporation for purposes of purchase accounting. The
purchase price of approximately $6.0 million attributed to the MMS acquisition
represents the estimated fair value of the approximately 1.3 million shares of
Interact Common Stock issued to former MMS stockholders and includes certain
costs and fees incurred directly in connection with the business combination. In
accordance with purchase accounting, the total purchase price, including assumed
liabilities at their estimated fair values (which approximates book value), is
allocated to assets acquired at their estimated fair values. Assets acquired
include tangible assets (which fair values are estimated to approximate book
value) and identifiable intangible assets, such as products in varying stages of
development. The estimated value of products in development which are considered
to have attained technological feasibility, as such term is defined and
interpreted in accordance with generally accepted accounting principles, are
capitalized and amortized over lives of five years. The estimated value of
products in development which are not deemed to have attained technological
feasibility, as defined, are capitalized in purchase accounting and immediately
expensed subsequent to recording the business combination. The estimated value
attributable to contracts and agreements is capitalized and amortized over five
years.
 
     The Company's unaudited pro forma results of operations for the year ended
December 31, 1995 and the three months ended March 31, 1996, presented on the
basis that the business combination had occurred at the beginning of the
respective periods, are as follows (thousands of dollars, except per share

     Contemporaneous with the Merger, Interact received $2.0 million cash from
Baxter Healthcare Corporation ("Baxter"), the former majority owner of MMS,
pursuant to terms of a promissory note, bearing interest at prime plus 2%, due
the earlier of the closing date of Interact's initial public offering or
September 1,

NOTE 10. SUBSEQUENT EVENTS (CONTINUED)
1996 (or such later date under certain circumstances). In the event the initial
public offering does not occur on or prior to September 1, 1996, Interact may
extend the due date to September 1, 1997 in exchange for approximately 195,000
shares of Interact Common Stock. In the event the initial public offering occurs
before September 1, 1996, then immediately following such closing the principal
amount plus accrued interest (the "Amount Owed") shall be converted into
Interact Common Stock by issuing such number of shares as determined by dividing
the Amount Owed by the public offering price. The promissory note is subject to
terms and conditions of a Credit Agreement, which prohibits or limits, among
other things, dividends or other capital distributions, issuances of Interact
common stock or options or warrants to acquire such stock, incurrence of
additional indebtedness, sales of assets, repayment of existing indebtedness,
and transactions with shareholders or affiliates. Additionally, on May 24, 1996,
in exchange for existing MMS promissory notes payable to Baxter having a
combined total principal amount of $550,000, Interact issued 8% promissory notes
to Baxter in the amounts of $350,000 and $200,000 having the same maturity date
as the $2.0 million convertible note and agreed to issue immediately following
the closing of the initial public offering such number of shares of Interact
Common Stock as determined by dividing $350,000 by the public offering price.
The $350,000 note may be extended to September 1997 at Interact's option in
exchange for approximately 34,000 shares of Interact Common Stock.
 
     In May and June 1996, the Company entered into employment contracts with
certain of its executive officers covering two- and three-year periods and
providing for base compensation, potential bonuses, severance pay under certain
circumstances, and other standard and customary employment-related benefits.
 
     In connection with the Merger, certain employees and consultants of Ixion
and MMS converted approximately $503,000 of accrued compensation in exchange for
approximately 62,000 shares of Interact Common Stock and payment of payroll
related withholdings. Accrued compensation was converted at a rate of one share
for each $7.50 of accrued payables, a price determined by the Company's Board of
Directors not to be less than the estimated fair market value of such shares at
the agreement date.
 
     As a result of the Merger, the Company paid fees to a financial consultant
in the amount of approximately $132,000 in full settlement of amounts due
pursuant to terms of a consulting agreement.
 
     In May 1996, Interact entered into a distribution agreement with Baxter,
pursuant to which Baxter has obtained a co-exclusive right to distribute the
Company's existing product for use in connection with certain specific
applications. Under terms of the distribution agreement, Baxter has been granted
an exclusive right to provide healthcare providers and their affiliates with
certain product software. The Company has retained all other rights, except as
otherwise set forth below, with respect to the sales and distribution of
products based upon this technology. Baxter has provided the Company with
certain minimum order guarantees and has agreed not to promote, purchase, sell
or distribute any products that are directly competitive with the products
distributed on behalf of the Company pursuant to the distribution agreement.
Baxter also has a right to negotiate distribution agreements for any future
products the Company develops in certain specific other fields. The term of the
agreement is five years, and may be extended for an additional five years at
Baxter's discretion. The parties can each terminate the distribution agreement
under certain circumstances. Further, pursuant to an agreement between Baxter
and the Company, Baxter is entitled to obtain the right to produce or cause
third parties to produce its product requirements in the event that the Company
is unable to supply its requirements in a timely manner.
 
     In May 1996, the Company granted to certain Company officers, directors and
employees options to purchase 255,000 shares of Interact Stock at $6.30 per
share, such exercise price being the estimated fair market value as of the date
of grant as determined by the Compensation Committee of the Company's Board of
Directors. Options have a term of ten years and generally vest 25% after one
year of continued service and ratably thereafter over the remaining three years
of a four-year vesting period.

     In June 1996, the Company's Board of Directors, subject to stockholder
approval, adopted a 1996 Stock Option Plan (the "1996 Plan"), such plan to
become effective when the Company's initial public offering registration
statement becomes effective. The 1996 Plan will serve as the successor equity
incentive program to Ixion's Stock Option Plan, which has been assumed by
Interact. A total of one million shares have been authorized for issuance under
the 1996 Plan, including approximately 380,000 shares reserved for issuance
under options outstanding. In addition, the Company's Board of Directors,
subject to stockholder approval, adopted an Employee Stock Purchase Plan
covering an aggregate of 200,000 shares of Interact Stock.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Partners of Medical Media Systems:
 
     We have audited the accompanying balance sheets of Medical Media Systems (a
New Hampshire development stage partnership) as of December 31, 1994 and 1995,
and the related statements of operations, changes in partners' equity and cash
flows for each of the three years then ended and for the period from November
25, 1992 (date of inception) to December 31, 1995. These financial statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Medical Media Systems as of
December 31, 1994 and 1995 and the results of its operations and its cash flows
for each of the three years then ended and from November 25, 1992 (date of
inception) to December 31, 1995, in conformity with generally accepted
accounting principles.

                             MEDICAL MEDIA SYSTEMS
                       (A DEVELOPMENT STAGE PARTNERSHIP)
 
                         NOTES TO FINANCIAL STATEMENTS
 
 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     Organization -- Medical Media Systems ("MMS" or "the Partnership"), a New
Hampshire general partnership in the development stage, was organized on
November 25, 1992 for the purpose of engaging in research, development and
commercialization of virtual reality and other advanced visualization as it
pertains to an operating room in a medical environment.
 
     Depreciation -- Research and development equipment is carried at cost, less
accumulated depreciation. The Partnership follows the policy of charging to
operating expenses annual amounts of depreciation which allocates the cost of
property and equipment over their estimated useful lives. The Partnership
estimates that research and development equipment has a useful life of five
years, furniture has a useful life of seven years and leasehold improvements
have a useful life of 39 years. Expenditures for repairs and maintenance are
expensed when incurred and betterments are capitalized.
 
     Organization expense -- Organization expense includes legal expenses
relating to the organization of the Partnership and will be amortized over five
years.
 
     Patents -- The Partnership capitalizes legal fees incurred to obtain
patents. Patents will be amortized over 15 years when issued.
 
     Cash and cash equivalents -- For purposes of the statement of cash flows,
the partnership considers all highly liquid short-term investments with an
original maturity of three months or less to be cash equivalents. The majority
of the Partnership's cash is held in one Hanover, New Hampshire based commercial
bank. At times, the FDIC insurance limit may be exceeded.
 
     Income taxes -- These statements do not include provisions for federal
income taxes, since any income or loss is reported on the applicable federal
returns of the respective general partners.
 
     Use of estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Interim Financial Statements -- The interim financial data as of and for
the three months ended March 31, 1995 and 1996 is unaudited; however, in the
opinion of Partnership management, the interim data includes all adjustments,
consisting only of normal recurring adjustments necessary for a fair statement
of results for the interim periods. The 1996 interim period results of
operations are not necessarily indicative of results for the entire year.
 
     Effect of Recently Issued Accounting Standards -- Recently issued
accounting standards having relevant applicability to the Partnership consists
primarily of Statement of Financial Accounting Standards No. 121 ("SFAS No.
121"), which establishes accounting standards for, among other things, the
impairment of long-lived assets and certain identifiable intangibles. SFAS No.
121 is effective for fiscal years beginning after December 15, 1995 and is not
expected to have a significant effect, if any, in the Company's financial
condition or results of operations.
 
 2. COMMITMENTS AND CONTINGENCIES:
 
     License agreement -- The Partnership has entered into a licensing agreement
with a related party of Baxter Medical Media Holdings, Inc. ("Baxter"). Under
the license agreement, MMS has granted the licensee exclusive rights to make,
have made, use and sell any product in the field of knee arthroscopic training
and surgery developed by MMS. In consideration of the licenses granted, the
Partnership will receive royalties

 2. COMMITMENTS AND CONTINGENCIES (CONTINUED)
on net sales of all patented products or copyrighted software sold by the
licensee. See Note 7 -- Subsequent Events regarding the termination of this
license agreement.
 
     Consulting agreements -- The Partnership has entered into consulting
agreements with five individuals to perform research services. Under these
agreements, MMS has agreed to pay an aggregate annual amount of $375,000 to
these individuals. MMS may terminate or amend these agreements at its
discretion. Payments under these agreements amounted to $209,219, $276,816 and
$126,680, respectively, for the years ended December 31, 1993, 1994 and 1995 and
to $639,752 since the date of inception.
 
     Research agreement -- On January 2, 1995, the Partnership entered into a
research agreement with The Trustees of Dartmouth College through the New
Hampshire Industrial Research Center to develop additional clinical products.
The New Hampshire Industrial Research Center has committed $50,000 to this
project. MMS is obligated to make contributions in the amount of $200,000.
 
     Lease commitments -- The Partnership leases its facilities and equipment
under noncancelable lease arrangements. On August 1, 1994, the Partnership
entered into a three-year agreement to lease office space in West Lebanon, New
Hampshire. The Partnership also obtained one three-year renewal option. Minimum
annual lease payments will amount to $32,278 for the lease term. In addition,
MMS will be required to pay its proportionate share of building expenses.
Building rent expense amounted to $15,934 and $39,799, respectively, for the
years ended December 31, 1994 and 1995. Rent expense under equipment leases
amounted to $12,285 for the year ended December 31, 1995. Future minimum lease
payments under equipment leases were as follows: 1996 -- $14,275;
1997 -- $13,305; 1998 -- $1,991.
 
 3. RETIREMENT PLAN:
 
     The Partnership adopted a defined contribution, salary reduction plan
during 1994 which covers all employees aged 21 or over. Each employee may elect
to defer a percentage of their salary into the plan, subject to annual maximums
as prescribed by the Internal Revenue Service. The Partnership does not intend
to make matching contributions.
 
 4. PARTNERSHIP CAPITAL STRUCTURE:
 
     The Partnership is organized as a New Hampshire general partnership under
the New Hampshire Uniform Partnership Act. MMS Founders Group Limited
Partnership ("MMS, L.P.") and Baxter Medical Media Holdings, Inc. ("Baxter") are
the sole general partners. MMS, L.P. has been designated the managing general
partner.
 
     MMS, L.P., in exchange for a 49% general partnership interest in Medical
Media Systems, contributed all of its proprietary rights, both tangible and
intangible, in regard to its research and development of virtual reality and
other advanced visualization.
 
     Baxter, in exchange for a 51% general partnership interest in Medical Media
Systems, agreed to contribute $5,100,000 of capital subject to the achievement
of certain milestones agreed upon by Baxter and MMS. As of December 31, 1995 the
Partnership had received $4,887,991. Prior to the organization of MMS, Baxter
contributed $212,009 to a predecessor corporation. In addition, Baxter has
options to contribute additional capital subject to the achievement of
additional milestones agreed upon by Baxter and MMS. If the options to
contribute additional capital are exercised, Baxter's Partnership interest would
increase.
 
     During 1995 and 1994, Baxter contributed $2,160,000 of capital in exchange
for an additional 9% Partnership interest.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
 5. RELATED PARTY TRANSACTIONS:
 
     During 1995, the Partnership received $400,000 from Baxter as a 6% demand
note payable. There are no fixed repayment terms.
 
     During 1995, the Partnership contracted with a related party of Baxter to
provide regulatory support for its products under development. As of December
31, 1995, the Partnership had incurred $75,000 of expense, of which $45,000 was
included in accounts payable at the end of the year.
 
 6. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     In accordance with FASB Statement 107, Disclosures about Fair Values of
Financial Instruments, which is effective for the year ended December 31, 1995,
the Partnership estimates that the carrying amounts of all financial
instruments, such as cash and accounts payable approximated their fair values
due to the short-term maturity of these instruments. These estimates are
subjective in nature and involve uncertainties and matters of significant
judgment and therefore cannot be determined with precision. Changes in
assumptions could affect estimates. It is not practicable to estimate the fair
value of the related party note payable.
 
 7. SUBSEQUENT EVENTS:
 
     Note payable -- In April 1996, the Partnership received an additional
advance of $150,000 from a related party as a short-term note payable. The
promissory note bears interest at 6% and is due on demand.
 
     Reorganization and merger -- In accordance with terms of a merger
agreement, in May 1996, the Partnership reorganized as a corporation and changed
its name to Interact Medical Technologies Corporation ("Interact"). Subsequent
to the reorganization, Interact merged its operations with Ixion, Inc.
("Ixion"). Ixion stockholders received shares of Interact common stock
("Interact Common Stock") in such amount that the former Ixion stockholders own
a majority of Interact Common Stock after the merger, and Interact received $2.0
million in cash from Baxter in exchange for a short-term promissory note, which
is convertible, under certain circumstances, at Interact's option into Interact
Common Stock. This business combination will be accounted for utilizing purchase
accounting. Inasmuch as former Ixion stockholders own a majority of Interact
Common Stock after the merger, Ixion is considered to be the acquiring
corporation for purposes of purchase accounting. In connection with the merger,
the license agreement with Baxter as described in Note 2 was terminated.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act. The Registrant's Bylaws also provide that the Registrant will indemnify its
directors and executive officers and may indemnify its other officers, employees
and other agents to the fullest extent not prohibited by Delaware law.
 
     The Registrant's Certificate of Incorporation provides for the elimination
of liability for monetary damages for breach of the directors' fiduciary duty of
care to the Registrant and its stockholders. These provisions do not eliminate
the directors' duty of care and, in appropriate circumstances, equitable
remedies such as injunctive or other forms of non-monetary relief will remain
available under Delaware law. In addition, each director will continue to be
subject to liability for breach of the director's duty of loyalty to the
Registrant, for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for any transaction from which the
director derived an improper personal benefit, and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision does not affect a director's responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws.
 
     Pursuant to authorization provided under the Certificate of Incorporation,
the Registrant has entered into indemnification agreements with each of its
directors and officers. Generally, the indemnification agreements attempt to
provide the maximum protection permitted by Delaware law as it may be amended
from time to time. Moreover, the indemnification agreements provide for certain
additional indemnification. Under such additional indemnification provisions,
however, an individual will not receive indemnification for judgments,
settlements or expenses if he or she is found liable to the Registrant (except
to the extent the court determines he or she is fairly and reasonably entitled
to indemnity for expenses), for settlements not approved by the Registrant or
for settlements and expenses if the settlement is not approved by the court. The
indemnification agreements provide for the Registrant to advance to the
individual any and all reasonable expenses (including legal fees and expenses)
incurred in investigating or defending any such action, suit or proceeding. In
order to receive an advance of expenses, the individual must submit to the
Registrant copies of invoices presented to him or her for such expenses. Also,
the individual must repay such advances upon a final judicial decision that he
or she is not entitled to indemnification.

<PAGE>   93
 
     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.
 
     Since May 31, 1993, the Registrant has sold and issued the following
unregistered securities:
 
     1. On May 24, 1996, the Registrant issued an aggregate of 1,253,333 shares

     2. On May 24, 1996, the Registrant issued an aggregate of 1,352,252 shares
of Common Stock to the stockholders of Ixion, Inc. ("Ixion") pursuant to that
certain Agreement and Plan of Reorganization by and among MMS and Ixion dated
May 24, 1996 (the "Merger Agreement"), in consideration of such stockholders
cancelling their shares of Ixion.
 
     3. On May 24, 1996, the Registrant issued an aggregate of 62,372 shares of
Common Stock to certain Ixion and MMS employees and consultants in consideration
of the cancellation of accrued but unpaid compensation owed to them by Ixion and
MMS.
 
     4. On May 24, 1996, pursuant to the terms of the Merger Agreement, the
Registrant assumed Ixion's obligations under letter agreements (the "Letter
Agreements") executed in favor of certain investors in Ixion's 1995 bridge
financing, pursuant to which a number of shares of Common Stock equal to
$2,200,000 divided by the initial public offering price for the sale of Common
Stock offered hereby will be issued immediately following the closing of this
Offering. Assuming an initial public offering price of $9.00 per share (the
midpoint of the range set forth on the cover page of this Prospectus), an
aggregate of 244,455 shares will be issued pursuant to the Letter Agreements.
 
     5. On May 24, 1996, pursuant to the terms of the Merger Agreement, the
Registrant assumed Ixion's obligations under certain promissory notes accruing
interest at the rate of 8% per annum in the aggregate principal amount of
$2,000,000 issued in connection with Ixion's 1995 bridge financing (the "Bridge
Notes"). The Bridge Notes provide for an additional issuance of 2,439 shares for
each $25,000 of principal amount outstanding under the Bridge Notes following
September 1, 1996.
 
     6. On May 24, 1996, the Registrant issued a promissory note to Baxter
Healthcare Corporation ("Baxter") accruing interest at the rate of 8% per annum
in the aggregate principal amount of $350,000 (the "$350,000 Note"). The
Registrant also entered into an agreement with Baxter (the "Baxter Letter")
pursuant to which a number of shares of Common Stock equal to $350,000 divided
by the initial public offering price for the shares of Common Stock offered
hereby will be issued to Baxter immediately following the closing of this
Offering. Assuming an initial public offering price of $9.00 per share (the
midpoint of the range set forth on the cover page of this Prospectus), an
aggregate of 38,889 shares will be issued to Baxter pursuant to the Baxter
Letter. If the $350,000 Note is not repaid in full on or before September 1,
1996, an additional 2,439 shares of Common Stock will be issued for each $25,000
outstanding.
 
     7. On May 24, 1996, the Registrant issued a convertible promissory note
bearing interest at a rate of 200 basis points above the prime rate to Baxter in
the aggregate principal amount of $2,000,000 (the "$2,000,000 Note"). The
$2,000,000 Note is convertible prior to September 1, 1996 into a number of
shares of Common Stock equal to $2,000,000 plus accrued interest divided by the
initial public offering price for the shares of Common Stock offered hereby.
Assuming the closing of this Offering occurs on August 24, 1996 and an initial
public offering price of $9.00 (the midpoint of the range set forth on the cover
page of this Prospectus), an aggregate of 227,964 shares will be issued to
Baxter pursuant to the $2,000,000 Note. If the $2,000,000 Note is not repaid in
full on or before September 1, 1996, an additional 2,439 shares of Common Stock
will be issued for each $25,000 outstanding.

      8. On May 24, 1996, pursuant to the terms of the Merger Agreement, the
Registrant assumed the stock options Ixion had granted to certain Ixion
employees, officers, directors and consultants to purchase an aggregate of
119,702 shares of Common Stock at a weighted average exercise price of $4.77.
 
      9. On May 24, 1996, pursuant to the Merger Agreement, the Registrant
assumed warrants Ixion had granted to purchase an aggregate of 73,162 shares of
Common Stock to certain warrantholders at a weighted average exercise price of
1.18 times the initial public offering price of the shares of Common Stock
offered hereby.
 
     10. On May 27, 1996, the Registrant granted options to purchase an
aggregate of 255,000 shares of Common Stock to certain employees, officers and
directors of the Registrant at an exercise price of $6.30 per share, pursuant to
the Registrant's then existing stock option plan.
 
     The sales and issuances of securities in the above transactions were deemed
to be exempt under the Act by virtue of Section 4(2) thereof and/or Regulation D
and Rule 701 promulgated thereunder as transactions not involving any public
offering. The purchasers in each case represented their intention to acquire the
securities for investment only and not with a view to the distribution thereof.
Appropriate legends were affixed to the stock certificates issued in such
transactions. Similar representations of investment intent were obtained and
similar legends imposed in connection with any subsequent transfers of any such
securities. The Registrant believes that all recipients had adequate access,
through employment or other relationships, to information about the Registrant
to make an informed investment decision.

ITEM 17. UNDERTAKINGS.
 
     The undersigned 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 for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of
 
                                      II-5
<PAGE>   97
 
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, 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 undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, 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, 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 of 1933, the Registrant
has duly caused this Registration Statement to be signed on its behalf by the

                     APPENDIX TO ELECTRONIC DOCUMENT FORMAT
                            DESCRIPTION OF GRAPHICS
 
     Pursuant to Paragraph 625 of the EDGAR User Manual, the following is an
explanation of the differences between the foregoing document in electronic
format and the corresponding printed document on
 
     1. Location: Outside Front Cover Page of Prospectus.
 
        Description: Interact Medical Technologies Corporation logo, below which
        is printed "INTERACT MEDICAL TECHNOLOGIES."
 
     2. Location: Inside Front Cover Page of Prospectus.
 
        Description: A graphic with the Company's logo described in Paragraph 1
        above. Below the logo is the caption, "CLOSED-LOOP MARKETING STRATEGY."
        Below this caption is a graphic of a closed loop labeled with the
        captions "GastroSim(TM)," "Preview(TM)," "DataFusion(TM)" and "Vascular
        Surgeons, Family Practitioners, Gastroenterologists, others." In the
        middle of the closed loop is the caption "Encompassing the Clinical
        Experience in Education, Training and MIS Procedures." In three circles
        intersecting the closed loop there are the captions "Interactive Virtual
        Reality Simulators," "Interactive 3D Modeling Services" and "Interactive
        CD-Rom titles." Placed around the closed loop are the captions "Training
        Room," "Operating Room" and "Medical School Classroom." Placed to the
        left and right of the closed loop are three pictures. The first picture
        depicts an individual operating GastroSim. The next picture depicts an
        individual observing a Preview model on a computer screen. The final
        picture depicts one screen from a CD-Rom product under development. The
        caption at the bottom left states "Preview(TM) and Interact's products
        under development are being designed to provide a comprehensive suite of
        interactive information tools that are designated to enhance clinical
        performance from the operating room to the medical school classroom."
 
     3. Location: Inside Front Cover Page of Prospectus -- Foldout.
 
        Description: A graphic with the Company's logo described in Paragraph 1
        above. Above the logo is the caption "MISSION STATEMENT." Below the logo
        is the caption "Interact Medical Technologies Corporation develops,
        markets and manufactures products designed to facilitate the effective
        use of minimally invasive surgical (MIS) procedures and enhance clinical
        performance." Below this caption is the caption "Interactive 3D Modeling
        Services." Below this caption is the caption "The Company's initial
        product, Preview(TM), allows the clinician to visualize and plan
        surgical procedures by interacting with the three dimensional model of
        the patient-specific anatomy." Below this caption are nine pictures of
        images of patient-specific anatomy generated using Preview. Below these
        pictures are the following captions: (i) "Each Preview(TM) model
        provides thousands of preoperative images and a detailed
        three-dimensional model of patient-specific anatomy" and "Preview(TM)
        allows the clinician to address clinical planning needs without making a
        sizeable investment in hardware, software and
       training."
 
     4. Location: Inside Front Cover Page of Prospectus -- Foldout.
 
        Description: At the top of the page is the caption "INTERACTIVE VIRTUAL
        REALITY SIMULATORS." Below this caption is the caption "Interact's
        initial IVR simulator, GastroSim(TM) (which is currently in the
        pre-production prototype stage), consists of a pavilion depicting two
        anatomical regions, the upper gastrointestinal ("UGI") and lower
        gastrointestinal ("LGI") tracts. GastroSim incorporates procedures
        designed for training medical personnel to conduct diagnostic tests and
        perform therapies on ulcers, polyps, cancers, bile stone removals and
        other UGI procedures, such as bronchoscopy, endotracheal tube placement
        and ultrasound echocardial procedures; teaching clinicians to manipulate
        sophisticated MIS medical devices and instruments; and evaluating the
        clinician's ability to accomplish these diagnostic and therapeutic
        maneuvers." Beneath this caption on the left is a picture of GastroSim.
        Below this picture is the caption "Interact is developing IVR simulators
        that consist of a platform which is a computer system that is capable of
        being reconfigured to control various pavilions, each consisting of a
        specific robotic mannequin depicting one of various
<PAGE>   100
 
        anatomical regions of the body in which diagnostic and therapeutic
        procedures are performed." On the right of the picture of the GastroSim
        is a picture of two of the introductory screens depicted on the
        GastroSim computer monitor as a simulation is begun. Below this picture
        is the caption "With its ability to provide in-depth evaluation of the
        clinician's performance, GastroSim can be used for accrediting,
        credentialling and privileging clinicians. Below this caption is a
        picture of GastroSim in operation with the term "GastroSim(TM)"
        superimposed next to a picture of a transverse colon generated by
        GastroSim labeled "Trans-verse Colon." Below these pictures is the
        caption "While performing procedures on a "virtual patient",
        GastroSim(TM) replicates the look, feel and sound of performing an
        actual procedure. Below this caption is the caption "INTERACTIVE CD-ROM
        TITLES." Below this caption is the caption "Interact is developing a new
        series of educational CD-ROMs for multimedia personal computers. These
        products are being designed to integrate aspects of the Company's
        simulation technology to create interactive illustrations of the
        best-demonstrated clinical practice." Beneath this caption are four
        pictures of screens from a CD-Rom product under development.

                      AGREEMENT AND PLAN OF REORGANIZATION

                  This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is
made and entered into as of May 24, 1996, by and among Medical Media Systems,
Inc., a Delaware corporation ("MMS"), and Ixion, Inc., a Delaware corporation
("Ixion").

                                    RECITALS

                  A. The Boards of Directors of Ixion and MMS believe it is in
the best interests of their respective companies and the stockholders of their
respective companies that Ixion and MMS combine into a single company through
the statutory merger of Ixion with and into MMS (the "Merger") and, in
furtherance thereof, have approved the Merger.

                  B. Pursuant to the Merger, among other things, the outstanding
shares of Ixion Common Stock, par value $0.01 per share ("Ixion Common Stock"),
shall be converted into shares of MMS Common Stock, par value $0.01 per share
("MMS Common Stock"), at the rate set forth herein.

                  C. Ixion and MMS desire to make certain representations and
warranties and other agreements in connection with the Merger.

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

                                   ARTICLE I

                                   THE MERGER

                  1.1 The Merger. At the Effective Time (as defined in Section
1.2) and subject to and upon the terms and conditions of this Agreement, the
Certificate of Merger attached hereto as Exhibit A (the "Certificate of Merger")
and the applicable provisions of the Delaware General Corporation Law ("Delaware
Law"), Ixion shall be merged with and into MMS, the separate corporate existence
of Ixion shall cease and MMS shall continue as the surviving corporation, except
that its name shall be changed to Interact Medical Technologies Corporation
("Interact"). MMS as the surviving corporation after the Merger is hereinafter
sometimes referred to as the "Surviving Corporation."

                  1.2 Closing: Effective Time. The closing of the transactions
contemplated hereby (the "Closing") shall take place on the date of this
Agreement (the

                                       1.
<PAGE>   7
"Closing Date") at the offices of Brobeck, Phleger & Harrison LLP, or at such
other location as the parties hereto agree. In connection with the Closing, the
parties hereto shall cause the Merger to be consummated by filing the
Certificate of Merger with the Secretary of State of the State of Delaware and
with the Recorder of the County in which the registered office of each of Ixion
and MMS is located, in accordance with the relevant provisions of Delaware Law
(the time of such filing or such later time as is specified in the Certificate
of Merger being the "Effective Time").

                  1.3 Effect of the Merger. At the Effective Time, the effect of
the Merger shall be as provided in this Agreement, the Certificate of Merger and
the applicable provisions of Delaware Law. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the property,
rights, privileges, powers and franchises of Ixion shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Ixion shall become the
debts, liabilities and duties of the Surviving Corporation with the effect set
forth in Section 259 of Delaware Law.

                  1.4 Certificate of Incorporation; Bylaws.

                      (a) At the Effective Time, the Certificate of
Incorporation of MMS, as in effect immediately prior to the Effective Time,
shall be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by Delaware Law and such Certificate of
Incorporation; provided, however, that Article I of the Certificate of
Incorporation of the Surviving Corporation shall be amended to read as follows:
"The name of the corporation is Interact Medical Technologies Corporation."

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

                  1.5 Directors and Officers. At the Effective Time, the
directors of the Surviving Corporation shall be Charles Hutchinson, Bruce
Sturman, David Hon, James Calliouette, Leo McKenna, Steven Pieper and John Lyon.
The officers of Ixion and Steven Pieper shall be elected as the initial officers
of the Surviving Corporation and all officers of MMS shall resign immediately
prior to the Effective Time.

                  1.6 Effect on Capital Stock. By virtue of the Merger and
without any action on the part of Ixion or the holders of any of the following
securities:

                      (a) Conversion of Ixion Common Stock. At the Effective
Time, each share of Ixion Common Stock issued and outstanding immediately prior
to the Effective Time (other than any shares of Ixion Common Stock to be
cancelled pursuant to Section 1.6(b)) will be canceled and extinguished and be
converted automatically into the right to receive 0.48774 shares of Common Stock
of the Surviving Corporation (the "Exchange Ratio").

                                       2.

treasury stock immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.

                      (c) Ixion Stock Options and Warrants. At the Effective
Time, the Ixion 1994 Stock Option Plan (the "Ixion Stock Option Plan"), and the
options set forth on Schedule 4.2(a) to purchase Ixion Common Stock then
outstanding under the Ixion Stock Option Plan and the other outstanding options
and warrants to acquire Ixion Common Stock set forth on Schedule 4.2(a) shall be
assumed by the Surviving Corporation in accordance with Section 4.2.

                      (d) Ixion Promissory Notes. At the Effective Time, all
rights to acquire Ixion Common Stock pursuant to the promissory notes (the
"Securities") listed on attached Schedule 1.6(d) (which Schedule 1.6(d) shall
also set forth the number of shares of Ixion Common Stock that each holder of
Securities shall have the right to acquire and the price, expiration and other
terms related thereto), shall be assumed by the Surviving Corporation in
accordance with Section 4.5.

                      (e) Ixion Investor Letter Agreements. At the Effective
Time, all rights to acquire Ixion Common Stock pursuant to the investor letter
agreements (the "Investor Letters") listed on attached Schedule 1.6(e) (which
Schedule 1.6(e) shall also set forth the method of calculating the number of
shares to be issued pursuant to the Investor Letters), shall be assumed by the
Surviving Corporation in accordance with Section 4.6

                      (f) Consulting Agreements. At the Effective Time, all
rights to acquire Ixion Common Stock pursuant to the consulting agreements (the
"Consulting Agreements") listed on attached Schedule 1.6(f) (which Schedule

accordance with Section 4.7.

                      (g) Fractional Shares. No fraction of a share of Common
Stock of the Surviving Corporation will be issued and the number of shares of
Common Stock of the Surviving Corporation to be issued shall be rounded up to
the nearest whole share.

                      (h) MMS Common Stock. Each share of MMS Common Stock
issued and outstanding immediately prior to the Effective Time shall continue to
represent one (1) share of issued and outstanding common stock of the Surviving
Corporation and shall not be affected by the Merger.

                                       3.
<PAGE>   9
                  1.7  Surrender of Certificates.

                      (a) Exchange Agent. American Stock Transfer Company shall
act as exchange agent (the "Exchange Agent") in the Merger.

                      (b) Interact to Provide Common Stock. Promptly after the
Effective Time, Interact shall make available to the Exchange Agent for exchange
in accordance with this Article I, through such reasonable procedures as
Interact may adopt, the shares of Interact Common Stock issuable pursuant to
Section 1.6 in exchange for shares of Ixion Common Stock outstanding immediately
prior to the Effective Time.

                      (c) Exchange Procedures. Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each holder of
record of a certificate or certificates (the "Certificates") which immediately
prior to the Effective Time represented outstanding shares of Ixion Common
Stock, whose shares were converted into the right to receive shares of Common
Stock of the Surviving Corporation pursuant to Section 1.6, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon receipt of the
Certificates by the Exchange Agent, and shall be in such form and have such
other provisions as MMS may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of Common Stock of the Surviving Corporation. Upon surrender
of a Certificate for cancellation to the Exchange Agent or to such other agent
or agents as may be appointed by MMS, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holder of such Certificate shall be entitled to receive in exchange therefor
a certificate representing the number of whole shares of Common Stock of the
Surviving Corporation which such holder has the right to receive pursuant to
Section 1.6, and the Certificate so surrendered shall forthwith be canceled.
Until so surrendered, each outstanding Certificate that, prior to the Effective
Time, represented shares of Ixion Common Stock will be deemed from and after the
Effective Time, for all corporate purposes, other than the payment of dividends,
to evidence the ownership of the number of full shares of Common Stock of the
Surviving Corporation into which such shares of Ixion Common Stock shall have
been so converted.

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

                                       4.
<PAGE>   10
for the provisions of this Section 1.7(d)) with respect to such shares of Common
Stock of the Surviving Corporation.

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

                      (f) No Liability. Notwithstanding anything to the contrary
in this Section 1.7, none of the Exchange Agent, the Surviving Corporation or
any party hereto shall be liable to any person for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

                  1.8 No Further Ownership Rights in Ixion Common Stock. All
shares of Common Stock of the Surviving Corporation issued upon the surrender
for exchange of shares of Ixion Common Stock in accordance with the terms hereof
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Ixion Common Stock, and there shall be no further

provided, however, that the Surviving Corporation may, in its discretion and as

officers and directors of Ixion are fully authorized in the name of Ixion or
otherwise to take, and will take, all such lawful and necessary action, so long
as such action is not inconsistent with this Agreement.

                     REPRESENTATIONS AND WARRANTIES OF MMS

                  In this Agreement, any reference to any event, change,

and to carry on its business as now being conducted and as proposed to be
conducted and is duly qualified to do business and is in good standing in each
jurisdiction in which the failure to be so qualified and in good standing would
have a Material Adverse Effect on MMS. MMS has delivered a true and correct copy
of its Certificate of Incorporation (the "MMS Certificate of Incorporation"),
and Bylaws (the "MMS Bylaws") or other charter documents, as applicable, of MMS,
each as amended to date, to Ixion. MMS is not in violation of any of the
provisions of the MMS Certificate of Incorporation or the MMS Bylaws or

or indirectly own any equity or similar interest in, or any interest convertible
or exchangeable or exercisable for, any equity or similar interest in, any
corporation, partnership, joint venture or other business association or entity.

         2.2 Capital Structure. The authorized capital stock of MMS consists of
10,000,000 shares of Common Stock, $0.01 par value, of which there were issued
and outstanding immediately prior to the transactions contemplated hereby

forth on Schedule 2.2. There are no other outstanding shares of capital stock or
voting securities and no outstanding commitments to issue any shares of capital
stock or voting securities. All outstanding shares of MMS Common Stock are duly
authorized, validly issued, fully paid and non-assessable and are free of any
liens or encumbrances other than any liens or encumbrances created by or imposed
upon the holders thereof, and are not subject to preemptive rights or rights of
first refusal created by statute, the MMS Certificate of Incorporation or the
MMS Bylaws or any agreement to which MMS is a party or by which it is bound.
Except for the rights created pursuant to this Agreement, there are no other
options, warrants, calls, rights, commitments or agreements of any character to
which MMS is a party or by which it is bound obligating MMS to issue, deliver,
sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased
or redeemed, any shares of capital stock of MMS or obligating MMS to grant,
extend, accelerate the vesting of, change the price of, or otherwise amend or
enter into any such option, warrant, call, right, commitment or agreement. There

authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of MMS, including, without
limitation, the requisite approval of MMS's stockholders. This Agreement has
been duly executed and delivered by MMS and constitutes the valid and binding
obligation of MMS enforceable against MMS in accordance with its terms. The
execution and delivery of this Agreement by MMS does not, and the consummation
of the transactions contemplated hereby will not, conflict with, or result in
any violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under (i) any provision of the MMS
Certificate of Incorporation or the MMS Bylaws, or (ii) any material mortgage,
indenture, lease, contract or other agreement or instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to MMS or any of its properties or assets, except where
such conflict, violation, default, termination, cancellation or acceleration
with respect to the foregoing provisions of (ii) would not have had and would
not reasonably be expected to have a Material Adverse Effect on MMS. No
additional consent, approval, order or authorization of, or registration,
declaration or filing with, any court, administrative agency or commission or
other governmental authority or instrumentality ("Governmental Entity") is
required by or with respect to MMS in connection with the execution and delivery
of this Agreement or the

                                       7.
<PAGE>   13
consummation of the transactions contemplated hereby except for the filing of
the Certificate of Merger as provided in Section 1.2 and such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not have a Material Adverse Effect on MMS and would not prevent, or
materially alter or delay any of the transactions contemplated by this
Agreement.

                  2.4 Financial Statements. MMS has delivered to Ixion its
audited financial statements (balance sheet and profit and loss statement,
statement of stockholders' equity and statement of changes in financial
position) at December 31, 1995, and for the fiscal year then ended and its
unaudited financial statements (balance sheet and profit and loss statement) at
and for the 3-month period ended March 31, 1996 (the "MMS Financial
Statements"). The MMS Financial Statements are complete and correct in all
material respects and have been prepared in accordance with GAAP applied on a
consistent basis throughout the periods indicated and with each other, except
that unaudited MMS Financial Statements may not contain all footnotes required
by GAAP and have not been condensed as required by GAAP. The MMS Financial .
Statements accurately set out and describe the financial condition and operating
results of MMS as of the dates, and for the periods, indicated therein, subject
to normal year-end adjustments. Except as set forth in the MMS Financial
Statements, MMS has no liabilities, contingent or otherwise, other than (a)
liabilities incurred in the ordinary course of business since March 31,1996 (b)
liabilities set forth on the MMS Disclosure Schedule, and (c) obligations under
contracts and commitments incurred in the ordinary course of business and not
required under GAAP to be reflected in the MMS Financial Statements, which, in
both cases, individually or in the aggregate, are not material to the financial
condition or operating results of MMS. MMS maintains and will continue to
maintain a standard system of accounting established and administered in
accordance with GAAP.

                  2.5 Absence of Certain Changes. Since March 31,1996, MMS has
conducted its business in the ordinary course consistent with past practice and
there has not occurred: (i) any change, event or condition (whether or not
covered by insurance) that has resulted in, or might reasonably be expected to
result in, a Material Adverse Effect to MMS; (ii) any acquisition, sale,
mortgage, pledge or transfer of any material asset of MMS other than in the
ordinary course of business and consistent with past material change in
depreciation or amortization policies or rates) by MMS or any practice; (iii)
any material change in accounting methods or practices (including any material
revaluation by MMS of any of its assets; (iv) any declaration, setting aside, or
payment of a dividend or other distribution with respect to the shares of MMS,
or any direct or indirect redemption, purchase or other acquisition by MMS of
any of its shares of capital stock; (v) any material contract entered into by
MMS, other than in the ordinary course of business and as provided to Ixion, or
any material amendment or termination of, or default under, any material
contract to which MMS is a party or by which it is bound; (vi) any indebtedness
incurred by MMS, except such as may have been incurred in the ordinary course of
business and consistent with past practice; (vii)

                                       8.
<PAGE>   14
any loan made or agreed to be made by MMS, nor has MMS become liable or agreed
to become liable as a guarantor with respect to any loan; or (viii) any
negotiation or agreement by MMS to do any of the things described in the
preceding clauses (i) through (vii) (other than negotiations with Ixion and its
representatives regarding the transactions contemplated by this Agreement) .

                  2.6 Subsidiaries. MMS does not presently own or control,
directly or indirectly, an interest in any other corporation, association or
business entity.

                  2.7 Absence of Undisclosed Liabilities. MMS has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the MMS
Financial Statements, (ii) those set forth on the MMS Disclosure Schedule, (iii)
those incurred in the ordinary course of business and not required to be set
forth in the MMS Financial Statements under GAAP, (iv) those incurred in the
ordinary course of business since March 31, 1996, and consistent with past
practice; and (v) those incurred in connection with the execution of this
Agreement.

                  2.8 Material Contracts. All contracts, agreements and
instruments to which MMS is a party, which involve future revenue to or payments
by MMS that are material, are listed in the MMS Disclosure Schedule
(collectively, the "MMS Material Contracts"). Except as set forth in the MMS
Disclosure Schedule, all the MMS Material Contracts are in full force and effect
in all material respects. MMS has no notice that any party to any such MMS
Material Contract intends to cancel, withdraw, modify or amend such MMS Material
Contract. MMS is not in material default or breach, and no event has occurred or
will occur by reason of the transactions contemplated in this Agreement which
would constitute a default or breach, where such default or breach would entitle
another party to this Agreement to accelerate or terminate such MMS Material
Contract or otherwise impose a material penalty or forfeiture thereunder
(whether with or without notice, lapse of time or the happening or occurrence of
any other event), under any MMS Material Contract.

                  2.9 Litigation. There is no private or governmental action,
suit, proceeding, claim, arbitration or investigation pending before any agency,
court or tribunal, foreign or domestic, or, to the knowledge of MMS threatened
against MMS or any of its properties or any of its officers or directors (in
their capacities as such) that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect on MMS. There is no
judgment, decree or order against MMS or, to the knowledge of MMS any of its
respective directors or officers (in their capacities as such), that could
prevent, enjoin, alter or materially delay any conduct or practice in connection
with the business engaged in by MMS or any of the transactions contemplated by
this Agreement, or that could reasonably be expected to have a Material Adverse
Effect on MMS.

                                       9.
<PAGE>   15
                  2.10 Restrictions on Business Activities. There is no material
agreement, judgment, injunction, order or decree binding upon MMS which has the
effect of prohibiting or materially impairing any current or future business
practice of MMS, any acquisition of property by MMS or the conduct of business
by MMS as currently conducted or as proposed to be conducted by MMS.

                  2.11 Governmental Authorization. MMS has obtained each
federal, state, county, local or foreign governmental consent, license, permit,
grant, or other authorization of a governmental entity (i) pursuant to which MMS
currently operates or holds any interest in any of its properties or (ii) that
is required for the operation of MMS's business or the holding of any such
interest ((i) and (ii) herein collectively called "MMS Authorizations"), and
all of such MMS Authorizations are in full force and effect, except where the
failure to obtain or have any of such MMS Authorizations could not reasonably be
expected to have a Material Adverse Effect on MMS.

                  2.12 Title to Property. MMS has good and valid title to all of
its properties, interests in properties and assets, real and personal, reflected
in the MMS Financial Statements or acquired after March 31, 1996 (except
properties, interests in properties and assets sold or otherwise disposed of
since March 31,1996 in the ordinary course of business), or in the case of

all mortgages, liens, pledges, charges or encumbrances of any kind or character,
except (i) the lien of current taxes not yet due and payable, (ii) such
imperfections of title, liens and easements as do not and will not materially
detract from or interfere with the use of the properties subject thereto or
affected thereby, or otherwise materially impair business operations involving
such properties and (iii) liens securing debt which is reflected on the MMS
Financial Statements. The plants, property and equipment of MMS that are used in
the operations of its business are in good operating condition and repair. All
properties used in the operations of MMS are reflected in the Financial
Statements to the extent GAAP requires the same to be reflected. Schedule 2.12
identifies each parcel of real property owned or leased by MMS.

                  2.13     Intellectual Property.

                  (a) MMS owns, or is licensed or otherwise possesses legally
enforceable rights to use all patents, trademarks, trade names, service marks,

Intellectual Property") that is used or currently proposed to be used in the
business of MMS as currently conducted or as currently proposed to be conducted
by MMS, except to the extent that the failure to have such rights have not had
and would not reasonably be expected to have a Material Adverse Effect on MMS.

                                       10.
<PAGE>   16
                  (b) Schedule 2.13 lists (i) all patents and patent
applications and all registered and unregistered trademarks, trade names and
service marks, registered and unregistered copyrights, and maskworks, which MMS

Property, including the jurisdictions in which each such MMS Intellectual
Property right has been issued or registered or in which any application for
such issuance and registration has been filed, (ii) all material licenses,
sublicenses and other agreements as to which MMS is a party and pursuant to
which any person is authorized to use any MMS Intellectual Property, and (iii)
all material licenses, sublicenses and other agreements as to which MMS is a

product that is material to its business.

                  (c) To the knowledge of MMS, there is no material unauthorized
use, disclosure, infringement or misappropriation of any MMS Intellectual
Property rights, any trade secret material to MMS, or any MMS Intellectual
Property right of any third party to the extent licensed by or through MMS, by
any third party, including any employee or former employee of MMS. MMS has not
entered into any agreement to indemnify any other person against any charge of
infringement of any intellectual property, other than indemnification provisions
contained in purchase orders arising in the ordinary course of business.

                  (d) MMS is not, nor will it be as a result of the execution
and delivery of this Agreement or the performance of its obligations under this
Agreement, in breach of any license, sublicense or other agreement relating to
the MMS Intellectual Property or MMS Third Party Intellectual Property Rights,
the breach of which would have a Material Adverse Effect on MMS.

                  (e) To MMS's knowledge, all patents, registered trademarks,
service marks and copyrights held by MMS are valid and subsisting. MMS (i) has
not been sued in any suit, action or proceeding which involves a claim of

of any trade secret or other proprietary right of any third party; (ii) has no
knowledge that the manufacturing, marketing, licensing or sale of its products
infringes any patent, trademark, service mark, copyright, trade secret or other
proprietary right of any third party, which such infringement would have a
Material Adverse Effect on MMS; and (iii) has not brought any action, suit or
proceeding for infringement of MMS Intellectual Property or breach of any
license or agreement involving MMS Intellectual Property against any third
party.

                  (f) MMS has secured valid written assignments from all
consultants and employees who contributed to the creation or development of MMS

                                       11.
<PAGE>   17
except where the failure to secure such assignments would not have a Material
Adverse Effect on MMS.

protect and preserve the confidentiality of all MMS Intellectual Property not
otherwise protected by patents, or patent applications or copyright ("MMS
Confidential Information"). To the knowledge of MMS, all use, disclosure or

Governmental Entity (a "Tax authority") responsible for the imposition of any
such tax (domestic or foreign), (ii) any liability for the payment of any
amounts of the type described above as a result of being a member

                                       13.
<PAGE>   19
of an affiliated, consolidated, combined or unitary group for any Taxable period
and (iii) any liability for the payment of any amounts of the type described
above as a result of any express or implied obligation to indemnify any other

withholding Tax returns and reports and information reports and returns required
to be filed with respect to Taxes. MMS is in full compliance with all terms and
conditions of any Tax exemptions or other Tax-sparing agreement or order of a
foreign government and the consummation of the Merger shall not have any adverse
effect on the continued validity and effectiveness of any such Tax exemptions or
other Tax-sparing agreement or order.

                 2.16 Employee Benefit Plans.

                      (a) Schedule 2.16 lists, with respect to MMS and any trade
or business (whether or not incorporated) which is treated as a single employer
with MMS (an "MMS ERISA Affiliate") within the meaning of Section 414(b), (c),
(m) or (o) of the Code, (i) all material employee benefit plans (as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")), (ii) each loan to a non-officer employee in excess of $50,000, loans
to officers and directors and any stock option, stock purchase, phantom stock,
stock appreciation right, supplemental retirement, severance, sabbatical,
medical, dental, vision care, disability, employee relocation, cafeteria benefit
(Code section 125) or dependent care (Code Section 129), life insurance or
accident insurance plans, programs or arrangements, (iii) all bonus, pension,
profit sharing, savings, deferred compensation or incentive plans, programs or
arrangements, (iv) other fringe or employee benefit plans, programs or
arrangements that apply to senior management of MMS and that do not generally
apply to all employees, and (v) any current or former employment or executive
compensation or severance agreements, written or otherwise, as to which
unsatisfied obligations of MMS of greater than $50,000 remain for the benefit
of, or relating to, any present or former employee, consultant or director of
MMS (together, the "MMS Employee Plans").

                  (b) MMS has furnished to Ixion a copy of each of the MMS
Employee Plans and related plan documents (including trust documents, insurance
policies or contracts, employee booklets, summary plan descriptions and other
authorizing documents, and, to the extent still in its possession, any material
employee communications relating thereto) and has, with respect to each MMS
Employee Plan which is subject to ERISA reporting requirements, provided copies
of the Form 5500 reports filed for the last three plan years. Any MMS Employee
Plan intended to be qualified under Section 401(a) of the Code has either
obtained from the Internal Revenue Service a favorable determination letter as
to its qualified status under the Code, including all amendments to the Code
effected by the Tax Reform Act of 1986 and subsequent legislation, or has
applied to the Internal Revenue Service for such a determination letter prior to
the expiration of the requisite period under applicable Treasury Regulations or
Internal Revenue Service pronouncements in which to apply for

                                       14.
<PAGE>   20
such determination letter and to make any amendments necessary to obtain a
favorable determination. MMS has also furnished Ixion with the most recent
Internal Revenue Service determination letter issued with respect to each such
MMS Employee Plan, and nothing has occurred since the issuance of each such
letter which could reasonably be expected to cause the loss of the tax-qualified
status of any MMS Employee Plan subject to Code Section 401(a).

                      (c) (i) None of the MMS Employee Plans promises or
provides retiree medical or other retiree welfare benefits to any person; (ii)
there has been no "prohibited transaction," as such term is defined in Section
406 of ERISA and Section 4975 of the Code, with respect to any MMS Employee
Plan, which could reasonably be expected to have, in the aggregate, a Material
Adverse Effect; (iii) each MMS Employee Plan has been administered in accordance
with its terms and in compliance with the requirements prescribed by any and all
statutes, rules and regulations (including ERISA and the Code), except as would
not have, in the aggregate, a Material Adverse Effect, and MMS and each MMS
ERISA Affiliate have performed all obligations required to be performed by them
under, are not in any respect in default under or violation of, and have no
knowledge of any default or violation by any other party to, any of the MMS
Employee Plans, which default or violation could reasonably be expected to have
a Material Adverse Effect on MMS; (iv) neither MMS nor any MMS ERISA Affiliate
is subject to any liability or penalty under Sections 4976 through 4980 of the
Code or Title I of ERISA with respect to any of the MMS Employee Plans; (v) all

any MMS Employee Plan have been made on or before their due dates and a
reasonable amount has been accrued for contributions to each MMS Employee Plan
for the current plan years; (vi) with respect to each MMS Employee Plan, no
""reportable event"" within the meaning of Section 4043 of ERISA (excluding any

year included in the MMS Financial Statements.

                  2.17 Certain Agreements Affected by the Merger. Neither the

discrimination in employment, terms and conditions of employment, wages, hours

any obligations under COBRA with respect to any former employees or qualifying
beneficiaries thereunder, except for obligations that would not have a Material

                                  ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF IXION

                  Except as disclosed on Schedule 3 attached hereto (the "Ixion

               3.1 Organization, Standing and Power. Ixion is a corporation duly
organized, validly existing and in good standing under tile laws of its
jurisdiction of organization. Ixion has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted and is duly qualified to do business and is in good standing in
each jurisdiction in which the failure to be so qualified and in good standing
would have a Material Adverse Effect on Ixion. Ixion has delivered a true and
correct copy of its Certificate of Incorporation, as amended (the "Ixion        
Certificate of Incorporation"), and Bylaws, as amended (the "Ixion Bylaws") or
other charter documents, as applicable, of Ixion, each as amended to date, to

of Incorporation or the Ixion Bylaws or equivalent organizational documents.
There are no outstanding subscriptions, options, warrants, puts, calls, rights,

obligating Ixion to issue, transfer, sell, purchase, redeem or otherwise
acquire any such securities. Ixion does not directly or indirectly own any
equity or similar interest in, or any interest convertible or exchangeable or

partnership, joint venture or other business association or entity.

                  3.2 Capital Structure. The authorized capital stock of Ixion
consists of 10,000,000 shares of Common Stock, $0.01 par value, of which there

hereby 2,772,464 shares. Such shares of Ixion Common Stock are owned of record
as set forth on Schedule 3.2. There are no other outstanding shares of capital
stock or voting securities and no outstanding commitments to issue any shares of
capital stock or voting securities other than pursuant to (i) the exercise of
options and warrants outstanding as of the date hereof, as set forth in Schedule
4.2(a), (ii) the Securities, (iii) the Investor Letters and (iv) the Consulting
Agreements. All outstanding shares of Ixion Common Stock are duly

                                       18.
<PAGE>   24
authorized, validly issued, fully paid and non-assessable and are free of any
liens or encumbrances other than any liens or encumbrances created by or imposed
upon the holders thereof, and are not subject to preemptive rights or rights of
first refusal created by statute, the Ixion Certificate of Incorporation Bylaws
of Ixion or any agreement to which Ixion is a party or by which it is bound.

been issued pursuant to option exercises or direct stock purchases, 125,432
shares are subject to outstanding, unexercised options, and no shares are
subject to outstanding stock purchase rights. Except as set forth above and
except for (i) the rights created pursuant to this Agreement, (ii) Ixion's right
to repurchase any unvested shares under the Ixion Stock Option Plan and (iii)
Ixion's obligations to issue shares of its Common Stock pursuant to the
Securities, the Investor Letters and the Consulting Agreements, there are no
other options, warrants, calls, rights, commitments or agreements of any
character to which Ixion is a party or by which it is bound obligating Ixion to
issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered,
sold, repurchased or redeemed, any shares of capital stock of Ixion or
obligating Ixion to grant, extend, accelerate the vesting of, change the price
of, or otherwise amend or enter into any such option, warrant, call, right,
commitment or agreement. There are no contracts, commitments or agreements
relating to voting, purchase or sale of Ixion's capital stock (i) between or
among Ixion and any of its stockholders and (ii) to the best of Ixion's
knowledge, between or among any of Ixion's stockholders. The terms of the Ixion
Stock Option Plan permit the assumption or substitution of options to purchase
Common Stock of the Surviving Corporation as provided in this Agreement, without
the consent or approval of the holders of such securities, the Ixion
stockholders, or otherwise and without any acceleration of the exercise schedule
or vesting provisions in effect for those options. True and complete copies of
all agreements and instruments relating to or issued under the Ixion Stock
Option Plan have been made available to MMS and such agreements and instruments
have not been amended, modified or supplemented, and there are no agreements to
amend, modify or supplement such agreements or instruments in any case from the

by all necessary corporate action on the part of Ixion, including, without
limitation, approval of Ixion's Stockholders. This Agreement has been duly
executed and delivered by Ixion and constitutes the valid and binding obligation
of Ixion enforceable against Ixion in accordance with its terms. The execution

transactions contemplated hereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under (i) any provision of the Ixion
Certificate of Incorporation or the Ixion Bylaws, or (ii) any

                                       19.
<PAGE>   25
material mortgage, indenture, lease, contract or other agreement or instrument,
permit, concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Ixion or any of its properties or
assets, except where such conflict, violation, default, termination,
cancellation or acceleration with respect to the foregoing provisions of (ii)
would not have had and would not reasonably be expected to have a Material
Adverse Effect on Ixion. No additional consent, approval, order or authorization
of, or registration, declaration or filing with any Governmental Entity is
required by or with respect to Ixion in connection with the execution and
delivery of this Agreement or the consummation of the transactions contemplated
hereby except for the filing of the Certificate of Merger as provided in Section
1.2 and such other consents, authorizations, filings, approvals and
registrations which, if not obtained or made, would not have a Material Adverse
Effect on Ixion and would not prevent, or materially alter or delay any of the
transactions contemplated by this Agreement.

                  3.4 Financial Statements. Ixion has delivered to MMS its
audited financial statements (balance sheet and profit and loss statement,
statement of stockholders' equity and statement of changes in financial
position) at December 31, 1995, and for the fiscal year then ended and its
unaudited financial statements (balance sheet and profit and loss statement) at
and for the 3-month period ended March 31, 1996 (the "Ixion Financial
Statements"). The Ixion Financial Statements are complete and correct in all
material respects and have been prepared in accordance with GAAP applied on a
consistent basis throughout the periods indicated and with each other, except
that unaudited Ixion Financial Statements may not contain all footnotes required
by GAAP. The Ixion Financial Statements accurately set out and describe the
financial condition and operating results of Ixion as of the dates, and for the
periods, indicated therein, subject to normal year-end adjustments. Except as
set forth in the Ixion Financial Statements, Ixion has no liabilities,
contingent or otherwise, other than (a) liabilities incurred in the ordinary
course of business since March 31, 1996, (b) liabilities set forth on the Ixion
Disclosure Schedule, and (c) obligations under contracts and commitments
incurred in the ordinary course of business and not required under GAAP to be
reflected in the Ixion Financial Statements, which, in both cases, individually
or in the aggregate, are not material to the financial condition or operating
results of Ixion. Ixion maintains and will continue to maintain a standard
system of accounting established and administered in accordance with GAAP.

                  3.5 Absence of Certain Changes. Since March 31,1996, Ixion has
conducted its business in the ordinary course consistent with past practice and
there has not occurred: (i) any change, event or condition (whether or not
covered by insurance) that has resulted in, or might reasonably be expected to
result in, a Material Adverse Effect to Ixion; (ii) any acquisition, sale,
mortgage, pledge or transfer of any material asset of Ixion other than in the
ordinary course of business and consistent with past practice; (iii) any
material change in accounting methods or practices (including any material
change in depreciation or amortization policies or rates) by Ixion or any
material revaluation by Ixion of any of its assets; (iv) any declaration,
setting aside, or

                                       20.
<PAGE>   26
payment of a dividend or other distribution with respect to the shares of Ixion,
or any direct or indirect redemption, purchase or other acquisition by Ixion of
any of its shares of capital stock; (v) any material contract entered into by
Ixion, other than in the ordinary course of business and as provided to MMS, or
any material amendment or termination of, or default under, any material
contract to which Ixion is a party or by which it is bound; (vi) any
indebtedness incurred by Ixion, except such as may have been incurred in the
ordinary course of business and consistent with past practice; (vii) any loan
made or agreed to be made by Ixion, nor has Ixion become liable or agreed to
become liable as a guarantor with respect to any loan; or (viii) any negotiation
or agreement by Ixion to do any of the things described in the preceding clauses
(i) through (vii) (other than negotiations with MMS and its representatives
regarding the transactions contemplated by this Agreement).

                  3.6 Subsidiaries. Ixion does not presently own or control,
directly or indirectly, an interest in any other corporation, association or
business entity.

                  3.7 Absence of Undisclosed Liabilities. Ixion has no material
obligations or liabilities of any nature (matured or unmatured, fixed or
contingent) other than (i) those set forth or adequately provided for in the
Ixion Financial Statements, (ii) those set forth on the Ixion Disclosure
Schedule, (iii) those incurred in the ordinary course of business and not
required to be set forth in the Ixion Financial Statements under GAAP, (iv)
those incurred in the ordinary course of business since March 31, 1996, and
consistent with past practice; and (v) those incurred in connection with the
execution of this Agreement.

                  3.8 Material Contracts. All contracts, agreements and
instruments to which Ixion is a party, which involve future revenue to or
payments by Ixion that are material, are listed in the Ixion Disclosure Schedule
(collectively, the "Ixion Material Contracts"). Except as set forth in the Ixion
Disclosure Schedule, all the Ixion Material Contracts are in full force and
effect in all material respects. Ixion has no notice that any party to any such
Ixion Material Contract intends to cancel, withdraw, modify or amend such Ixion
Material Contract. Ixion is not in material default or breach, and no event has
occurred or will occur by reason of the transactions contemplated in this
Agreement which would constitute a default or breach, where such default or
breach would entitle another party to this Agreement to accelerate or terminate
such Ixion Material Contract or otherwise impose a material penalty or
forfeiture thereunder (whether with or without notice, lapse of time or the
happening or occurrence of any other event), under any Ixion Material Contract.

                  3.9 Litigation. There is no private or governmental action,
suit, proceeding, claim, arbitration or investigation pending before any agency,
court or tribunal, foreign or domestic, or, to the knowledge of Ixion threatened
against Ixion or any of its properties or any of its officers or directors (in
their capacities as such) that, individually or in the aggregate, could
reasonably be expected to have a Material

                                       21.
<PAGE>   27
Adverse Effect on Ixion. There is no judgment, decree or order against Ixion or,
to the knowledge of Ixion any of its respective directors or officers (in their
capacities as such), that could prevent, enjoin, alter or materially delay any
conduct or practice in connection with the business engaged in by Ixion or any
of the transactions contemplated by this Agreement, or that could reasonably be
expected to have a Material Adverse Effect on Ixion.

                  3.10 Restrictions on Business Activities. There is no material
agreement, judgment, injunction, order or decree binding upon Ixion which has
the effect of prohibiting or materially impairing any current or future business
practice of Ixion, any acquisition of property by Ixion or the conduct of
business by Ixion as currently conducted or as proposed to be conducted by
Ixion.

                  3.11 Governmental Authorization. Ixion has obtained each
federal, state, county, local or foreign governmental consent, license, permit,
grant, or other authorization of a governmental entity (i) pursuant to which Mon
currently operates or holds any interest in any of its properties or (ii) that
is required for the operation of Ixion's business or the holding of any such
interest ((i) and (ii) herein collectively called "Ixion Authorizations"), and
all of such Ixion Authorizations are in full force and effect, except where the
failure to obtain or have any of such Ixion Authorizations could not reasonably
be expected to have a Material Adverse Effect on Ixion.

                  3.12 Title to Property. Ixion has good and valid title to all
of its properties, interests in properties and assets, real and personal,
reflected in the Ixion Financial Statements or acquired after March 31, 1996

materially detract from or interfere with the use of the properties subject
thereto or affected thereby, or otherwise materially impair business operations
involving such properties and (iii) liens securing debt which is reflected on
the Ixion Financial Statements. The plants, property and equipment of Ixion that
are used in the operations of its business are in good operating condition and
repair. All properties used in the operations of Ixion are reflected in the
Ixion Financial Statements to the extent GAAP requires the same to be reflected.
Schedule 3.12 identifies each parcel of real property owned or leased by Ixion.

be filed by it, have paid all Taxes shown thereon to be due and has provided
adequate accruals in accordance with GAAP in its financial statements for any

Ixion or is being asserted against Ixion other than liens for Taxes not yet due
and payable. No audit of any Tax Return of Ixion is being conducted by a Tax
authority. No extension of the statute of limitations on the assessment of any
Taxes has been granted by Ixion and is currently in effect. There is no
agreement, contract or arrangement to which Ixion is a party that may result in
the payment of any amount that would not be deductible by reason of Sections

accounting methods employed prior to the Merger. Ixion is not a party to any tax
sharing or tax allocation agreement nor does Ixion owe any amount under any such
agreement. Ixion is in full compliance with all terms and conditions of any Tax
exemptions or other Tax-sparing agreement or order of a foreign government and
the consummation of the Merger shall not have any adverse effect on the
continued validity and effectiveness of any such Tax exemptions or other
Tax-sparing agreement or order.

                  3.16 Employee Benefit Plans.

                       (a) Schedule 3.16 lists, with respect to Ixion and any
trade or business (whether or not incorporated) which is treated as a single
employer with Ixion (an "Ixion ERISA Affiliate") within the meaning of Section
414(b), (c), (m) or (o) of the Code, (i) all material employee benefit plans (as
defined in Section 3(3) of ERISA), (ii) each loan to a non-officer employee in
excess of $50,000, loans to officers and directors and any stock option, stock
purchase, phantom stock, stock appreciation right, supplemental retirement,
severance, sabbatical, medical, dental, vision care, disability, employee
relocation, cafeteria benefit (Code section 125) or dependent care (Code Section
129), life insurance or accident insurance plans, programs or arrangements,
(iii) all bonus, pension, profit sharing, savings, deferred compensation or
incentive plans, programs or arrangements, (iv) other fringe or employee benefit
plans, programs or arrangements that apply to senior management of Ixion and
that do not generally apply to all employees, and (v) any current or former
employment or executive compensation or severance agreements, written or
otherwise, as to which unsatisfied obligations of Ixion of greater than $50,000
remain for the benefit of, or relating to, any present or former employee,
consultant or director of Ixion (together, the "Ixion Employee Plans").

                       (b) Ixion has furnished to MMS a copy of each of the
Ixion Employee Plans and related plan documents (including trust documents,
insurance policies or contracts, employee booklets, summary plan descriptions
and other authorizing documents, and, to the extent still in its possession, any
material employee communications relating thereto) and has, with respect to each
Ixion Employee Plan which is subject to ERISA reporting requirements, provided
copies of the Form 5500 reports filed for the last three plan years. Any Ixion
Employee Plan intended to be qualified under Section 401(a) of the Code has
either obtained from the Internal Revenue Service a favorable determination
letter as to its qualified status under the Code, including all amendments to
the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or
has applied to the Internal Revenue Service for such a determination letter
prior to the expiration of the requisite period under applicable Treasury
Regulations or Internal Revenue Service pronouncements in which to apply for
such determination letter and to make any amendments necessary to obtain a
favorable determination. Ixion has also furnished MMS with the most recent
Internal Revenue Service determination letter issued with respect to each such
Ixion Employee Plan, and nothing has occurred since the issuance of each such
letter which could reasonably be expected to cause the loss of the tax-qualified
status of any Ixion Employee Plan subject to Code Section 401(a).

                       (c) (i) None of the Ixion Employee Plans promises or
provides retiree medical or other retiree welfare benefits to any person; (ii)
there has been no "prohibited transaction," as such term is defined in Section
406 of ERISA and Section 4975 of the Code, with respect to any Ixion Employee
Plan, which could reasonably be expected to have, in the aggregate, a Material
Adverse Effect; (iii) each Ixion Employee

                                       26.
<PAGE>   32
Plan has been administered in accordance with its terms and in compliance with
the requirements prescribed by any and all statutes, rules and regulations
(including ERISA and the Code), except as would not have, in the aggregate, a
Material Adverse Effect, and Ixion and each Ixion ERISA Affiliate have performed
all obligations required to be performed by them under, are not in any respect
in default under or violation of, and have no knowledge of any default or
violation by any other party to, any of the Ixion Employee Plans, which default
or violation could reasonably be expected to have a Material Adverse Effect on
Ixion; (iv) neither Ixion nor any Ixion ERISA Affiliate is subject to any
liability or penalty under Sections 4976 through 4980 of the Code or Title I of
ERISA with respect to any of the Ixion Employee Plans; (v) all material
contributions required to be made by Ixion or any Ixion ERISA Affiliate to any
Ixion Employee Plan have been made on or before their due dates and a reasonable
amount has been accrued for contributions to each Ixion Employee Plan for the
current plan years; (vi) with respect to each Ixion Employee Plan, no
"reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the thirty (30) day notice requirement has been waived
under the regulations to Section 4043 of ERISA) nor any event described in
Section 4062, 4063 or 4041 or ERISA has occurred; and (vii) no Ixion Employee
Plan is covered by, and neither Ixion nor any Ixion ERISA Affiliate has incurred
or expects to incur any liability under Title IV of ERISA or Section 412 of the
Code. With respect to each Ixion Employee Plan subject to ERISA as either an
employee pension plan within the meaning of Section 3(2) of ERISA or an employee
welfare benefit plan within the meaning of Section 3(1) of ERISA, Ixion has
prepared in good faith and timely filed all requisite governmental reports
(which were true and correct as of the date filed) and has properly and timely
filed and distributed or posted all notices and reports to employees required to
be filed, distributed or posted with respect to each such Ixion Employee Plan.
No suit, administrative proceeding, action or other litigation has been brought,
or to the best knowledge of Ixion is threatened, against or with respect to any
such Ixion Employee Plan, including any audit or inquiry by the IRS or United
States Department of Labor. Neither Ixion nor any Ixion ERISA Affiliate is a
party to, or has made any contribution to or otherwise incurred any obligation
under, any "multiemployer plan" as defined in Section 3(37) of ERISA.

                       (d) With respect to each Ixion Employee Plan, Ixion has
complied with (i) the applicable health care continuation and notice provisions
of COBRA and the proposed regulations thereunder and (ii) the applicable
requirements of the Family Leave Act of 1993 and the regulations thereunder,
except to the extent that such failure to comply would not, in the aggregate,
have a Material Adverse Effect.

                       (e) The consummation of the transactions contemplated by
this Agreement will not (i) entitle any current or former employee or other
service provider of Ixion, or any Ixion ERISA Affiliate to severance benefits or
any other payment, except as expressly provided in this Agreement, or (ii)
accelerate the time of payment or vesting, or increase the amount of
compensation due any such employee or service provider.

                                       27.
<PAGE>   33
                       (f) There has been no amendment to, written
interpretation or announcement (whether or not written) by Ixion, or any Ixion
ERISA Affiliate relating to, or change in participation or coverage under, any
Ixion Employee Plan which would materially increase the expense of maintaining
such Plan above the level of expense incurred with respect to that Plan for the
most recent fiscal year included in the Ixion Financial Statements.

                  3.17 Certain Agreements Affected by the Merger. Neither the
execution and delivery of this Agreement nor the consummation of the transaction
contemplated hereby will (i) result in any payment (including, without
limitation, severance, unemployment compensation, golden parachute, bonus or
otherwise) becoming due to any director or employee of Ixion, (ii) materially
increase any benefits otherwise payable by Ixion or (iii) result in the
acceleration of the time of payment or vesting of any such benefits.

                  3.18 Employee Matters. Ixion is in compliance in all respects
with all currently applicable laws and regulations respecting employment,
discrimination in employment, terms and conditions of employment, wages, hours
and occupational safety and health and employment practices, and is not engaged
in any unfair labor practice, except where the failure to be in compliance or
the engagement in such unfair labor practices would not have a Material Adverse
Effect on Ixion. There are no pending claims against Ixion under any workers
compensation plan or policy or for long term disability. Ixion has not incurred
any obligations under COBRA with respect to any former employees or qualifying
beneficiaries thereunder, except for obligations that would not have a Material
Adverse Effect on Ixion. There are no controversies pending or, to the knowledge
of Ixion, threatened, between Ixion and any of its respective employees, which
controversies have or could reasonably be expected to have a Material Adverse
Effect on Ixion. Ixion is not a party to any collective bargaining agreement or
other labor unions contract nor does Ixion know of any activities or proceedings
of any labor union to organize any such employees.

                  3.19 Interested Party Transactions. Ixion is not indebted to
any director, officer, employee or agent of Ixion (except for amounts due as
normal salaries and bonuses and in reimbursement of ordinary expenses), and no
such person is indebted to Ixion.

                  3.20 Insurance. Ixion has policies of insurance and bonds of
the type and in amounts customarily carried by persons conducting businesses or
owning assets similar to those of Ixion. There is no material claim pending
under any of such policies or bonds as to which coverage has been questioned,
denied or disputed by the underwriters of such policies or bonds. All premiums
due and payable under all such policies and bonds have been paid and Ixion is
otherwise in compliance in all material respects with

                                       28.
<PAGE>   34
the terms of such policies and bonds. Ixion has no knowledge of any threatened
termination of, or material premium increase with respect to, any of such
policies.

                  3.21 Compliance With Laws. Ixion has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state, local or foreign statute, law or regulation with respect to the
conduct of its business, or the ownership or operation of its business, except
for such violations or failures to comply as could not be reasonably expected to
have a Material Adverse Effect on Ixion.

                  3.22 Minute Book. The minute book of Ixion made available to
MMS contains a complete and accurate summary of all meetings of directors and
stockholders or actions by written consent since the time of incorporation of
Ixion through the date of this Agreement, and reflects all transactions referred
to in such minutes accurately in all material respects.

                  3.23 Brokers' and Finders' Fees. Ixion has not incurred, nor
will it incur, directly or indirectly, any liability for brokerage or finders'
fees or agents' commissions or investment bankers' fees or any similar charges
in connection with this Agreement or any transaction contemplated hereby.

                  3.24 Complete Copies of Materials. Ixion has delivered or made

Merger is in the best interests of the stockholders of Ixion and is on terms

warranties made by Ixion herein or in any Schedule hereto, including the Ixion
Disclosure Schedule, or certificate furnished by Ixion pursuant to this
Agreement, when all such documents are read together in their entirety, contains

                             ADDITIONAL AGREEMENTS

         4.1      Intentionally omitted.

         4.2      Employee Benefit Plans.

         (a) At the Effective Time, the Ixion Stock Option Plan and each
outstanding option to purchase shares of Ixion Common Stock under the Ixion
Stock Option Plan, whether vested or unvested, and all other outstanding options
and warrants to acquire Ixion Common Stock, whether vested or unvested, will be
assumed by the Surviving Corporation. Schedule 4.2(a) hereto sets forth a true
and complete list as of the date hereof of all holders of outstanding options
under the Ixion Stock Option Plan, whether vested or unvested, and all holders
of other outstanding options and warrants, whether vested or unvested, including
the number of shares of Ixion capital stock subject to each such option or
warrant, the exercise or vesting schedule, the exercise price per share and the
term of each such option or warrant. Each such option or warrant so assumed by
the Surviving Corporation under this Agreement shall continue to have, and be
subject to, the same terms and conditions as applied to such option or warrant
immediately prior to the Effective Time, except that (i) such option or warrant
will be exercisable for that number of whole shares of Common Stock of the
Surviving Corporation equal to the product of the number of shares of Ixion
Common Stock that were issuable upon exercise of such option or warrant
immediately prior to the Effective Time multiplied by the Exchange Ratio and
rounded up to the nearest whole number of shares of Common Stock of the
Surviving Corporation, and (ii) the per share exercise price for the shares of
Common Stock of the Surviving Corporation issuable upon exercise of such assumed
option or warrant will be equal to the quotient determined by dividing the
exercise price per share of Ixion Common Stock at which such option or warrant
was exercisable immediately prior to the Effective Time by the Exchange Ratio,
rounded up to the nearest whole cent. Consistent with the terms of the documents
governing the outstanding options and warrants, the Merger will not terminate
any of the outstanding options or warrants or accelerate the exercisability or
vesting of such options or warrants or the shares of Common Stock of the
Surviving Corporation which will be subject to those options or warrants upon
the Surviving Corporation's assumption of the options and warrants in the
Merger. It is the intention of the parties that the options issued pursuant to
the Ixion Stock Option Plan which are assumed by the Surviving Corporation
qualify following the Effective Time as incentive stock options as defined in
Section 422 of the Code to the extent such options qualified as incentive stock
options prior to the Effective Time. Within 10 business days after the Effective
Time, the Surviving Corporation will issue to each person who, immediately prior
to the Effective Time was a holder of an outstanding option or warrant a
document evidencing the foregoing assumption of such option or warrant by the
Surviving Corporation.

         (b) All outstanding purchase options or repurchase rights which Ixion
may hold immediately prior to the Effective Time to repurchase shares of Ixion
Common

                                       30.
<PAGE>   36
Stock issued under the Ixion Stock Option Plan shall be transferred to the
Surviving Corporation in the Merger and shall thereafter be exercisable by the
Surviving Corporation upon the same terms and conditions in effect immediately
prior to the Effective Time, except that the shares purchasable thereunder shall
be shares of Common Stock of the Surviving Corporation and the price payable per
share by the Surviving Corporation shall be equal to the quotient determined by
dividing the purchase price per share at which the Ixion Common Stock was issued
under the Ixion Stock Option Plan by the Exchange Ratio and rounding the
resulting price per share payable by the Surviving Corporation up to the nearest
whole one-hundredth of a cent.

                  4.3 Public Offering. The Surviving Corporation shall use its
commercially reasonable efforts to effect within one hundred and eighty (180)
days following the Closing Date, pursuant to a registration statement under the
Securities Act of 1933, as amended, an underwritten public offering with
aggregate gross proceeds to the Surviving Corporation of at least $15,000,000.
Baxter Healthcare Corporation ("Baxter") hereby agrees that the Surviving
Corporation, in its sole discretion, may select Kaufman Bros., L.P., as its sole
lead or co-lead underwriter for such public offering.

                  4.4 Employees. Set forth on Schedule 4.4 is a list of (i)
employees of Ixion to whom the Surviving Corporation will make an offer of
employment comparable to such employee's current position, and (ii) employees of
MMS who will continue their employment with the Surviving Corporation, effective
at the Closing. The Surviving Corporation will negotiate in good faith to hire
or retain, as the case may be, the employees on Schedule 4.4 and will
incentivize such employees consistent with its prior policies regarding
employees of MMS, including the issuance of options to purchase the Common Stock
of the Surviving Corporation in such amounts and on such terms as determined by
the Surviving Corporation in its sole discretion. The Surviving Corporation
shall have no obligation to make an offer of employment to any employee of Ixion
except those listed on Schedule 4.4.

                  4.5 Promissory Notes. At the Effective Time, the Securities
will be assumed by the Surviving Corporation. Schedule 1.6(d) hereto sets forth
a true and complete list as of the date hereof of all holders of the Securities.
The Securities so assumed by the Surviving Corporation under this Agreement
shall continue to have, and be subject to, the same terms and conditions, except
that the holders of such Securities will be entitled to receive that number of
whole shares of Common Stock of the Surviving Corporation equal to the product
of the number of shares of Ixion Common Stock that would have been issuable
pursuant to such Securities multiplied by the Exchange Ratio and rounded up to
the nearest whole number of shares of Common Stock of the Surviving Corporation.
Within 10 business days after the Effective Time, the Surviving Corporation will
issue to each person who, immediately prior to the Effective Time was a holder
of any Securities a document evidencing the foregoing assumption of such
Securities by the Surviving Corporation.

1.6(f) hereto sets forth a true and complete list as of the date hereof of all
of the Consulting Agreements. The Consulting Agreements so assumed by the
Surviving Corporation under this Agreement shall continue to have, and be
subject to, the same terms and conditions, except that the holders of such
Consulting Agreements will be entitled to receive that number of whole shares of
the Surviving Corporation's Common Stock equal to the product of the number of
shares of Ixion Common Stock that would have been issuable pursuant to such
Consulting Agreements multiplied by the Exchange Ratio and rounded to the
nearest whole number of shares of the Surviving Corporation's Common Stock.
Within ten (10) business days after the Effective Time, the Surviving
Corporation will issue to each person who, immediately prior to the Effective
Time was a party to any Consulting Agreement a document evidencing the foregoing

                  5.3 Interpretation. When a reference is made in this Agreement
to Exhibits, such reference shall be to an Exhibit to this Agreement unless
otherwise indicated. The words "include," "includes" and "including" when used
herein shall be deemed in each case to be followed by the words "without
limitation." The phrase "made available" in this Agreement shall mean that the
information referred to has been made available if requested by the party to
whom such information is to be made available. The phrases "the date of this
Agreement", "the date hereof", and terms of similar import, unless the context
otherwise requires, shall be deemed to refer to April 25, 1996. The table of
contents and headings contained in this Agreement are for reference purposes
only and shall not affect in any way the meaning or interpretation of this
Agreement.

                  5.4 Counterparts. This Agreement may be executed in one or
more counterparts, all of which shall be considered one and the same agreement
and shall become effective when one or more counterparts have been signed by
each of the parties and delivered to the other parties, it being understood that
all parties need not sign the same counterpart.

                  5.5 Entire Agreement; Nonassignability; Parties in Interest.
This Agreement and the documents and instruments and other agreements
specifically referred to herein or delivered pursuant hereto, including the
Exhibits, the Schedules, including the Ixion Disclosure Schedule and the MMS
Disclosure Schedule (a) constitute the entire agreement among the parties with
respect to the subject matter hereof and

                                       34.
<PAGE>   40
supersede all prior agreements and understandings, both written and oral, among
the parties with respect to the subject matter hereof, except for the
Confidentiality Agreement, which shall continue in full force and effect, and
shall survive any termination of this Agreement or the Closing, in accordance
with its terms; (b) are not intended to confer upon any other person any rights
or remedies hereunder, except as set forth in Sections 1.6-1.9, 4.3, and 5.11;
and shall not be assigned by operation of law or otherwise except as otherwise
specifically provided.

                  5.6 Severability. In the event that any provision of this
Agreement, or the application thereof, becomes or is declared by a court of
competent jurisdiction to be illegal, void or unenforceable, the remainder of
this Agreement will continue in full force and effect and the application of
such provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further agree
to replace such void or unenforceable provision of this Agreement with a valid
and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of such void or unenforceable provision.

                  5.7 Amendment. The boards of directors of the parties hereto
may cause this Agreement to be amended at any time by execution of an instrument
in writing signed on behalf of each of the parties hereto; provided that an
amendment made subsequent to adoption of the Agreement by the stockholders of
Ixion or MMS shall not (i) alter or change the amount or kind of consideration
to be received on conversion of the Ixion Common Stock, (ii) alter or change any
term of the Certificate of Incorporation of the Surviving Corporation to be
effected by the Merger, or (iii) alter or change any of the terms and conditions
of the Agreement if such alteration or change would adversely affect the holders
of Ixion Common Stock or MMS Common Stock.

                  5.8 Remedies Cumulative. Except as otherwise provided herein,
any and all remedies herein expressly conferred upon a party will be deemed
cumulative with and not exclusive of any other remedy conferred hereby, or by
law or equity upon such party, and the exercise by a party of any one remedy
will not preclude the exercise of any other remedy.

                  5.9 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware (without regard
to its principles of conflicts of law).

                  5.10 Rules of Construction. The parties hereto agree that they
have been represented by counsel during the negotiation, preparation and
execution of this Agreement and, therefore, waive the application of any law,
regulation, holding or rule of construction providing that ambiguities in an
agreement or other document will be construed against the party drafting such
agreement or document.

warranties of Medical Media Systems, Inc. ("MMS") in the Agreement and Plan of
Reorganization dated as of May 24, 1996 (the "Agreement"), by and among Ixion,
Inc. ("Ixion") and MMS (the "Disclosure Schedule").

        Except as otherwise stated, all capitalized terms used herein shall have
the meanings given them in the Agreement. Section numbers used herein correspond
to the Section numbers in the Agreement. Any matter specifically described and
set forth herein as an exception to a Section of the Agreement or specifically
described and set forth in a Schedule to this Agreement shall be deemed to
constitute an exception (to the extent specifically described) to all other

SECTION 2.5 - ABSENCE OF CERTAIN CHANGES.

1.        Prior to the consummation of the transactions contemplated by the
          Agreement, Medical Media Systems, a New Hampshire general partnership
          ("MMS-GP") and the predecessor entity to MMS, was converted to a
          Delaware corporation.

2.        MMS-GP entered into a Credit Agreement and related Demand Promissory
          Note for borrowings in the amount of $550,000 with Baxter Healthcare
          Corporation, a Delaware corporation ("Baxter"), as of April 10, 1996.



SECTION 2.7 - ABSENCE OF UNDISCLOSED LIABILITIES.

1.        The Kriegsman Group has asserted that MMS has agreed to pay the
          Kriegsman Group a fee should a merger be consummated between Ixion and
          MMS. Baxter has agreed that it shall be responsible for the fee to be
          paid to the Kriegsman Group, if any.

2.        MMS is a party to a Cooperative Agreement dated January 2,1995 with
          the Trustees of Dartmouth College whereby MMS is obligated to purchase
          services valued at $200,000. As of the date of the Agreement, MMS has
          purchased services valued at approximately $70,000.

3.        MMS is a party to a Development and License Agreement dated January
          13,1993 with MusculoGraphics, Inc. ("MG") whereby MMS agreed to pay MG
          a total of $465,000 for consulting services and $200,000 upon
          termination of the consulting services under certain circumstances. As
          of the date of the Agreement, MMS has completed payment of the amounts
          owed for consulting services and does not believe that it is obligated
          to make payments to MG as a result of the termination of consulting
          services. Additionally, MMS is liable to MG for certain royalties in
          the event that certain future products or services incorporate
          products licensed from MG.

4.        MMS is a party to an agreement dated October 17, 1994 with Baxter
          whereby Baxter provides regulatory legal services to MMS for fees in

          right of first refusal with respect to any invention in the "medical

7.  Microsoft License. MMS is currently shipping commercial versions of its 
    PREVIEW SURGERY PLANNING SOFTWARE product using the MacIntosh version of 
    Microsoft's Reality Labs(RL) software product. This is being done on the 
    oral and E-mail understanding that Microsoft is granting MMS a royalty-free 
    license to use this software. However, MMS has not yet received the signed 
    written license agreement from Microsoft. MMS understands that it will 
    receive a signed written license agreement for this software as soon as the 
    license agreement has been prepared by the Microsoft legal department.

8.  Bucholz Patent. Last year a vendor IGT/Pixsys. suggested to MMS that MMS 
    might need to acquire a license under U.S. Patent No. 5,383,454 issued to 
    Bucholz, depending on whether certain products were developed by MMS. Some 
    preliminary work was done to review this patent but this work was set aside 
    as product emphasis evolved. MMS

10.     General Electric Patents. MMS understands that the General Electric
        Company may own one or more patents relating to modeling processes
        similar to those used by MMS in connection with its PREVIEW products.
        MMS does not know how the existence of any such patents might impact its

                               MATERIAL CONTRACTS

1.  Research, Option and License Agreement dated April 8, 1992 between Ixion and
    Ethicon Endo-Surgery ("Ethicon"), a division of Ethicon, Inc., a subsidiary
    of Johnson & Johnson Corporation (the "Ethicon Agreement"), pursuant to
    which Ixion granted Ethicon an exclusive world-wide license to make, have
    made, use, lease and sell or otherwise dispose of Ixion products relating to
    the use of Ixion technology in the Field defined in the Ethicon Agreement as
    "methods, processes, devices, and instruments for the simulation of
    endoscopic and minimally invasive surgery in humans through an extendable,
    multi-plane computer-based video laparoscopic surgical training apparatus
    with tactile feedback for the teaching of surgical skills."

    In September, 1995, Ethicon informed the Company that it believes it has
    certain rights beyond its license to the laparoscopic simulator. The Company
    believes there is no basis to support this position under the terms of the
    Ethicon Agreement as set forth above. Ixion is entitled to receive
    continuing royalty payments pursuant to the Ethicon Agreement.

    Pursuant to Section 5.5 of the Ethicon Agreement, Ethicon has not tendered
    to Ixion the $50,000 minimum royalty payment for the past quarter of the
    Royalty Year (as defined in the Ethicon Agreement). Pursuant to Section
    5.5.1 of the Ethicon Agreement, on April 24,1996 (the "Delivery Date"),
    Ixion delivered notice of Ixion's intention to convert Ethicon's exclusive
    license into a non-exclusive license. Ethicon has ninety (90) from the
    delivery date to make up any deficiencies in the minimum royalty payment for
    the past Royalty Year (as defined in the last Ethicon Agreement) to maintain
    its exclusive license as described above.

(ii) Material Licenses Dealing with Intellectual Property.

     1.  Research, Option and License Agreement dated April 8, 1992 between
         Ixion and Ethicon Endo-Surgery ("Ethicon"), a division of Ethicon,
         Inc., a subsidiary of Johnson & Johnson Corporation (the "Ethicon
         Agreement"), pursuant to which Ixion granted Ethicon an exclusive
         world-wide license to make, have made, use, lease and sell or otherwise
         dispose of Ixion products relating to the use of Ixion technology in
         the Field defined in the Ethicon Agreement as "methods, processes,
         devices, and instruments for the simulation of endoscopic and minimally
         invasive surgery in humans through an extendable, multi-plane
         computer-based video laparoscopic surgical training apparatus with
         tactile feedback for the teaching of surgical skills."

         In September, 1995, Ethicon informed the Company that it believes it
         has certain rights beyond its license to the laparoscopic simulator.
         The Company believes there is no basis to support this position under
         the terms of the Ethicon Agreement as set forth above. Ixion is
         entitled to receive continuing royalty payments pursuant to the Ethicon
         Agreement.

                                   ARTICLE IV

      (A) Classes of Stock. This corporation is authorized to issue two classes
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
The total number of shares of all classes of capital stock which this
corporation shall have authority to issue is fifteen million (15,000,000) of
which ten million (10,000,000) shares
<PAGE>   3
of the par value of one cent ($0.01) each shall be Common Stock and five million
(5,000,000) shares of the par value of one cent ($0.01) each shall be Preferred
Stock.

      (B) Powers, Preferences and Rights and Qualifications, Limitations and
Restrictions of Preferred Stock. The Preferred Stock may be issued from time to
time in one or more series. The Board of Directors is hereby authorized, by
filing a certificate pursuant to the Delaware General Corporation Law, to fix or
alter from time to time the designation, powers, preferences and rights of the
shares of each such series and the qualifications, limitations or restrictions
thereof, including without limitation the dividend rights, dividend rate,
conversion rights, voting rights, rights and terms of redemption (including
sinking fund provisions), redemption price or prices, and the liquidation
preferences of any wholly unissued series of Preferred Stock, and to establish
from time to time the number of shares constituting any such series and the
designation thereof, or any of them (a "Preferred Stock Designation"); and to
increase or decrease the number of shares of any series subsequent to the
issuance of shares of that series, but not below the number of shares of such
series then outstanding. In case the number of shares of any series shall be
decreased in accordance with the foregoing sentence, the shares constituting
such decrease shall resume the status that they had prior to the adoption of the
resolution originally fixing the number of shares of such series.

      (C) Rights, Preferences, Privileges and Restrictions of Common Stock.

          1. Dividend Rights. Subject to the prior or parity rights of holders
of all classes of stock at the time outstanding having prior or parity rights as

and as declared by the Board of Directors, out of any assets of this corporation
legally available therefor, such dividends as may be declared from time to time
by the Board of Directors.

          2. Redemption. The Common Stock is not redeemable upon demand of any
holder thereof or upon demand of this corporation.

          3. Voting Rights. The holder of each share of Common Stock shall have
the right to one vote, and shall be entitled to notice of any stockholders'
meeting in accordance with the bylaws of this corporation, and shall be entitled
to vote upon such matters and in such manner as may be provided by law.

      Every stockholder entitled to vote in any election of directors of the
corporation may cumulate such stockholder's votes and give one candidate a
number of votes equal to the number of directors to be elected multiplied by the
number of votes to which the stockholder's shares are otherwise entitled, or
distribute the stockholder's votes on the same principle among as many
candidates as such stockholder thinks fit. No stockholder,

                                       -2-

however, may cumulate such stockholder's votes for one or more candidates unless
(i) the names of such candidates have been properly placed in nomination, in
accordance with the bylaws of the corporation, prior to the voting, (ii) the
stockholder has given advance notice to the corporation of the intention to
cumulate votes in accordance with the bylaws, and (iii) the stockholder has
given proper notice to the other stockholders at the meeting, prior to voting,
of such stockholder's intention to cumulate such stockholder's votes. If any
stockholder has given proper notice, all stockholders may cumulate their votes
for any candidates who have been properly placed in nomination. The candidates
receiving the highest number of votes of the shares entitled to be voted for
them up to the number of directors to be elected by such shares shall be
declared elected.

                                   ARTICLE VI

      (A) Exculpation. 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, except for liability (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived any
improper personal benefit.

      (B) Indemnification. To the extent permitted by applicable law, this
corporation is also authorized to provide indemnification of (and advancement of
expenses to) such agents (and any other persons to which Delaware law permits
this corporation to provide indemnification) through bylaw provisions,
agreements with such agents or other persons, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the Delaware General
Corporation Law, subject only to limits created by applicable Delaware law
(statutory or non-statutory), with respect to actions for breach of duty to the
corporation, its stockholders, and others.

      (C) Effect of Repeal or Modification. Any repeal or modification of any of
the foregoing provisions of this Article VI shall be prospective and shall not
adversely affect any right or protection of a director, officer, agent or other
person existing at the time of, or increase the liability of any director of the
corporation with respect to any acts or omissions of such director occurring
prior to, such repeal or modification.

term of office of the first class to expire at the 1997 Annual Meeting of
Stockholders and the term of office of the second class to expire at the 1998
Annual Meeting of Stockholders. At each Annual Meeting of Stockholders following
such initial classification and election, directors elected to succeed those
directors whose terms expire shall be elected for a term of office to expire at
the second succeeding Annual Meeting of Stockholders after their election.

                                  ARTICLE VIII

      No holder of shares of stock of the corporation shall have any preemptive
or other right, except as such rights are expressly provided by contract, to
purchase or subscribe for or receive any shares of any class, or series thereof,
of stock of the corporation, whether now or hereafter authorized, or any
warrants, options, bonds, debentures or other securities convertible into,
exchangeable for or carrying any right to purchase any share of any class, or
series thereof, of stock; but such additional shares of stock and such warrants,
options, bonds, debentures or other securities convertible into, exchangeable
for or carrying any right to purchase any shares of any class, or series
thereof, of stock may be issued or disposed of by the Board of Directors to such
persons, and on such terms and for such lawful consideration as in its
discretion it shall deem advisable or as the corporation shall have by contract
agreed.

stockholders as set forth in the bylaws; and, provided further, that no
amendment or supplement to the bylaws adopted by the Board of Directors shall

        SECTION 2.06 Voting.

        (a) Each stockholder shall, at each meeting of the stockholders, be

stock of the Corporation having voting rights on the matter in question and
which shall have been held by him and registered in his name on the books of the
Corporation:

                (i) on the date fixed pursuant to Section 6.05 of these Bylaws
        as the record date for the determination of stockholders entitled to
        notice of and to vote at such meeting, or

                (ii) if no such record date shall have been so fixed, then (a)
        at the close of business on the day next preceding the day on which
        notice of the meeting shall be given or (b) if notice of the meeting
        shall be waived, at the close of business on the day next preceding the
        day on which the meeting shall be held.

        (b) Shares of its own stock belonging to the Corporation or to another
corporation, if a majority of the shares entitled to vote in the election of

be entitled to vote such stock. Persons whose stock is pledged shall be entitled

                                       2
<PAGE>   4
to vote, unless in the transfer by the pledgor on the books of the Corporation
he shall have expressly empowered the pledgee to vote thereon, in which case
only the pledgee, or his proxy, may represent such stock and vote thereon. Stock
having voting power standing of record in the names of two or more persons,
whether fiduciaries, members of a partnership, joint tenants in common, tenants
by entirety or otherwise, or with respect to which two or more persons have the
same fiduciary relationship, shall be voted in accordance with the provisions of
the General Corporation Law of the State of Delaware.

        (c) Any such voting rights may be exercised by the stockholder entitled
thereto in person or by his proxy appointed by an instrument in writing,
subscribed by such stockholder or by his attorney thereunto authorized and
delivered to the secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall provide for a longer period. The attendance at any meeting of a
stockholder who may theretofore have given a proxy shall not have the effect of
revoking the same unless he shall in writing so notify the secretary of the
meeting prior to the voting of the proxy. At any meeting of the stockholders all
matters, except as otherwise provided in the Certificate of Incorporation, in
these Bylaws or by law, shall be decided by the vote of a majority in voting
interest of the stockholders present in person or by proxy and entitled to vote
thereat and thereon, a quorum being present. The vote at any meeting of the
stockholders on any question need not be by ballot, unless so directed by the
chairman of the meeting. On a vote by ballot each ballot shall be signed by the
stockholder voting, or by his proxy, if there be such proxy, and it shall state
the number of shares voted.

        SECTION 2.07 List of Stockholders. The Secretary of the Corporation
shall prepare and make, at least ten (10) days before every meeting of

stockholder and the number of shares registered in the name of each stockholder.

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.

        SECTION 2.08 Judges. If at any meeting of the stockholders a vote by
written ballot shall be taken on any question, the chairman of such meeting may
appoint a judge or judges to act with respect to such vote. Each judge so
appointed shall first subscribe an oath faithfully to execute the duties of a
judge at such meeting with strict impartiality and according to the best of his
ability. Such judges shall decide upon the qualification of the voters and shall
report the number of shares represented at the meeting and entitled to vote on
such question, shall conduct and accept the votes, and, when the voting is
completed, shall ascertain and report the number of shares voted respectively
for and against the question. Reports of judges shall be in writing and
subscribed and delivered by them to the Secretary of the Corporation. The judges
need not be stockholders of the Corporation, and any officer of

                                       3
<PAGE>   5
the Corporation may be a judge on any question other than a vote for or against
a proposal in which he shall have a material interest.

        SECTION 2.09 Action Without Meeting. Any action required to be taken at
any annual or special meeting of stockholders of the Corporation, or any action
which may be taken at any annual or special meeting of such stockholders, may be
taken without a meeting, without prior notice and without a vote, if a consent
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. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

the Board. The Board may also provide that the Corporation shall reimburse each
such director for any expense incurred by him on account of his attendance at

such compensation nor the reimbursement of such expenses shall be construed to
preclude any director from serving the Corporation or its subsidiaries in any

shall be issued and shall be signed in the name of the Corporation by the
President or a Vice President, and by the Secretary or an Assistant Secretary or
by the Treasurer or an Assistant Treasurer. Any of or all of the signatures on
the certificates may be a facsimile. In case any officer, transfer agent or
registrar who has signed, or whose facsimile signature has been placed upon, any
such certificate, shall have ceased to be such officer, transfer agent or
registrar before such certificate is issued, such certificate may nevertheless
be issued by the Corporation with the same effect as though the person who
signed such certificate, or whose facsimile signature shall have been placed
thereupon, were such officer, transfer agent or registrar at the date of issue.
A record shall be kept of the respective names of the persons, firms or
corporations owning the stock represented by such certificates, the number and
class of shares represented by such certificates, respectively, and the
respective dates thereof, and in case of cancellation, the respective dates of
cancellation. Every certificate surrendered to the Corporation for exchange or

duly executed and filed with the Secretary, or with a transfer clerk or a
transfer agent appointed as provided in Section 6.03, and upon surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes thereon. The person in whose name shares of stock stand on the books
of the Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation. Whenever any transfer of shares shall be made for collateral
security, and not absolutely, such fact shall be so expressed in the entry of
transfer if, when the certificate or certificates shall be presented to the
Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

        SECTION 6.03 Regulations. The Board may make such rules and regulations
as it may deem expedient, not inconsistent with these Bylaws, concerning the
issue,

another may be issued in its place upon proof of such loss, theft, destruction,
or mutilation and upon the giving of a bond of indemnity to the Corporation in
such form and in such sum as the Board may direct; provided, however, that a new
certificate may be issued without requiring any bond when, in the judgment of
the Board, it is proper so to do.

        SECTION 6.05 Fixing Date for Determination of Stockholders of Record. In
order that the Corporation may determine the stockholders entitled to notice of

receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any other change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board may fix, in advance, a record date, which shall not be more than 60
nor less than 10 days before the date of such meeting, nor more than 60 days
prior to any other action. If in any case involving the determination of
stockholders for any purpose other than notice of or voting at a meeting of
stockholders or expressing consent to corporate action without a meeting the
Board shall not fix such a record date, the record date for determining
stockholders for such purpose shall be the close of business on the day on which
the Board shall adopt the resolution relating thereto. A determination of
stockholders entitled to notice of or to vote at a meeting of stockholders shall
apply to any adjournment of such meeting; provided, however, that the Board may

                                Indemnification

        SECTION 7.01 Action, Etc. Other Than by or in the Right of the
Corporation. The Corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Corporation) by reason of the
fact that he 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 expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Corporation, and with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did

                                       10
<PAGE>   12
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, that he had reasonable cause to believe that his
conduct was unlawful.

        SECTION 7.02 Actions, Etc., by or in the Right of the Corporation. The
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation to procure a judgment in its favor by reason of the
fact that he 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 expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

        SECTION 7.03 Determination of Right of Indemnification. Any
indemnification under Section 7.01 or 7.02 (unless ordered by a court) shall be
made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because he has met the applicable standard of
conduct set forth in Section 7.01 and 7.02. Such determination shall be made (i)
by the Board by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding, or (ii) if such a quorum is not
obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders.

        SECTION 7.04 Indemnification Against Expenses of Successful Party.
Notwithstanding the other provisions of this Article, to the extent that a
director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys fees) actually and
reasonably incurred by him in connection therewith.

        SECTION 7.05 Prepaid Expenses. Expenses incurred by an officer or
director in defending a civil or criminal action, suit or proceeding may be paid
by the Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount
unless it shall ultimately be determined that he is entitled to be indemnified
by the Corporation as authorized in this Article. Such expenses incurred by
other

                                       11
<PAGE>   13
employees and agents may be so paid upon such terms and conditions, if any, as
the Board deems appropriate.

        SECTION 7.06 Other Rights and Remedies. The indemnification provided by
this Article shall not be deemed exclusive of any other rights to which those
seeking indemnification may be entitled under any Bylaws, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

        SECTION 7.07 Insurance. Upon resolution passed by the Board, 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 and incurred by him in any
such capacity, or arising out of his status as such, whether or not the
Corporation would have the power to indemnify him against such liability under
the provisions of this Article.

        SECTION 7.08 Constituent Corporations. For the purposes of this Article,
references to "the Corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, so
that any person who is or was a director, officer, employee or agent of such a
constituent corporation or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article with respect to the resulting or
surviving corporation as he would if he had served the resulting or surviving
corporation in the same capacity.

        SECTION 7.09 Other Enterprises, Fines, and Serving at Corporation's
Request. For purposes of this Article, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the Corporation" as referred to in this
Article.

and figures showing that the Corporation was incorporated in the State of
Delaware and the year of incorporation.

amended or repealed, and new Bylaws may be made, (i) by the Board, by vote of a
majority of the number of directors then in office as directors, acting at any
meeting of the Board, or (ii) by the stockholders, at any annual meeting of
stockholders, without previous notice, or at any special meeting of
stockholders, provided that notice of such proposed amendment, modification,
repeal or adoption is given in the notice of special meeting. Any Bylaws made or
altered by the stockholders may be altered or repealed by either the Board or
the stockholders.

of Dover, County of Kent, State of Delaware.

                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

        Section 1. Place of Meetings. All meetings of the stockholders for the
election of Directors shall be held in the City of San Diego, State of
California, at such place as may be fixed from time to time by the Board of
Directors, or at such other place either within or without the State of Delaware
as shall be designated from time to time by the Board of Directors and stated in
the notice of the meeting. Meetings of stockholders for any other purpose may be
held at such time and place, within or without the State of Delaware, as shall
be stated in the notice of the meeting or in a duly executed waiver of notice
thereof.

        Section 2. Annual Meeting.

                      (a) The annual meeting of the stockholders of the
corporation, for the purpose of election of Directors and for such other
business as may lawfully come before it, shall be held on such date and at such
time as may be designated from time to time by the Board of Directors.

                      (b) At an annual meeting of the stockholders, only such
business shall be conducted as shall have been properly brought before the
meeting. To be properly brought before an annual meeting, business must be: (A)
specified in the notice of meeting (or any supplement thereto) given by or at
the direction of the Board of Directors, (B) otherwise properly brought before
the meeting by or at the direction of the Board of Directors, or (C) otherwise
properly brought before the meeting by a
<PAGE>   3
stockholder. For business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the corporation. To be timely, a 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. A stockholder's notice to the Secretary shall
set forth as to each matter the stockholder proposes to bring before the annual
meeting: (i) a brief description of the business desired to be brought before
the annual meeting and the reasons for conducting such business at the annual
meeting, (ii) the name and address, as they appear on the corporation's books,
of the stockholder proposing such business, (iii) the class and number of shares
of the corporation which are beneficially owned by the stockholder, (iv) any
material interest of the stockholder in such business and (v) any other
information that is required to be provided by the stockholder pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as amended (the "1934
Act"), in his capacity as a proponent to a stockholder proposal. Notwithstanding
the foregoing, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act. Notwithstanding anything in these Bylaws to the contrary, no
business shall be conducted at any annual meeting except in accordance with the
procedures set forth in this paragraph (b). The chairman of the annual meeting
shall, if the facts warrant, determine and declare at the meeting that business
was not properly brought before the meeting and in accordance with the
provisions of this paragraph (b), and, if he should so determine, he shall so
declare at the meeting that any such business not properly brought before the
meeting shall not be transacted.

                      (c) Only persons who are nominated in accordance with the
procedures set forth in this paragraph (c) shall be eligible for election as
Directors. Nominations of persons for election to the Board of Directors of the
corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors or by any stockholder of the corporation entitled to vote
in the election of Directors at the meeting who complies with the notice
procedures set forth in this paragraph (c). Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made pursuant to
timely notice in writing to the Secretary of the corporation in accordance with
the provisions of paragraph (b) of this Section 2. Timely notice shall also be
given of any stockholder's intention to cumulate votes in the election of
Directors at a meeting if cumulative voting is available. Such stockholder's
notice shall set forth (i) as to each person, if any, whom the stockholder
proposes to nominate for election or re-election as a Director: (A) the name,
age, business address and residence address of such person, (B) the principal,
occupation or employment of such person, (C) the class and number of shares of
the corporation which are beneficially owned by such person,

                                       -2-
<PAGE>   4
(D) 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 nominations are to be made by the stockholder, and (E) any
other information relating to such person that is required to be disclosed in
solicitations of proxies for election of Directors, or is otherwise required, in
each case pursuant to Regulation 14A under the 1934 Act (including without
limitation such person's written consent to being named in the proxy statement,
if any, as a nominee and to serving as a Director if elected); and (ii) as to
such stockholder giving notice, the information required to be provided pursuant
to paragraph (b) of this Section 2 and, if cumulative voting is available to
such stockholder, whether such stockholder intends to request cumulative voting
in the election of Directors at the meeting. At the request of the Board of
Directors, any person nominated by a stockholder for election as a Director
shall furnish to the Secretary of the corporation that information required to
be set forth in the stockholder's notice of nomination which pertains to the
nominee. No person shall be eligible for election as a Director of the
corporation unless nominated in accordance with the procedures set forth in this
paragraph (c). The chairman of the meeting shall, if the facts warrant,
determine and declare at the meeting that a nomination was not made in
accordance with the procedures prescribed by these Bylaws, and if he should so
determine, he shall so declare at the meeting, and the defective nomination
shall be disregarded.

        Section 3. Notice of Annual Meeting. Written notice of the annual
meeting stating the place, date and hour of the meeting shall be given to each
stockholder entitled to vote at such meeting not less than ten (10) nor more
than sixty (60) days before the date of the meeting.

        Section 4. Voting List. The officer who has charge of the stock ledger
of the corporation shall prepare and make, at least ten 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 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.

        Section 5. Special Meetings. Special meetings of the stockholders, for
any purpose or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called by the president and shall be called
by the president or secretary at the request in writing of a majority of the
Board of Directors, or at the request in writing of stockholders owning at least
ten percent (10%) of the entire capital stock of the corporation issued and
outstanding and entitled to vote. Such request shall state the purpose or
purposes of the proposed meeting. The place, date and time of any special
meeting shall be determined by the Board of Directors. Such determination shall

                                       -3-
<PAGE>   5
include the record date for determining the stockholders having the right of and
to vote at such meeting.

        Section 6. Notice of Special Meeting. Written notice of a special
meeting stating the place, date and hour of the meeting and the purpose or
purposes for which the meeting is called shall be given not less than ten (10)
nor more than sixty (60) days before the date of the meeting, to each
stockholder entitled to vote at such meeting.

        Section 7. Action at Special Meeting. Business transacted at any special
meeting of stockholders shall be limited to the purposes stated in the notice.

        Section 8. Quorum and Adjournments.

                      (a) The holders of a majority 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 shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented. At such adjourned
meeting at which a quorum shall be present or represented any business may be
transacted which might have been transacted at the meeting as originally
notified. If the adjournment is for more than thirty 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.

                      (b) 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 statutes or of
the Certificate of Incorporation, a different vote is required, in which case
such express provision shall govern and control the decision of such question.

        Section 9. Voting Rights.

                      (a) Unless otherwise provided in the Certificate of
Incorporation each stockholder shall at every meeting of the stockholders be
entitled to one vote in person or by proxy for each share of the capital stock
having voting power held by such stockholder, but no proxy shall be voted on
after three years from its date, unless the proxy provides for a longer period.

                      (b) At all elections of Directors of the corporation each
stockholder having voting power shall be entitled to exercise the right of
cumulative voting as provided in the Certificate of Incorporation.

        Section 10. Action Without Meeting. No action shall be taken by the
stockholders of the corporation except at an annual or special meeting of
stockholders called in accordance with these Bylaws, and no action shall be
taken by the stockholders by written consent.

                                   ARTICLE III

                                    DIRECTORS

        Section 1. Classes, Number, Term of Office and Qualification. At the
1997 Annual Meeting of Stockholders, the directors shall be classified into two
classes, as nearly equal in number as possible, with the term of office of the
first class to expire at the 1997 Annual Meeting of Stockholders and the term of
office of the second class to expire at the 1998 Annual Meeting of Stockholders.
At each Annual Meeting of Stockholders following such initial classification and
election, directors elected to succeed those directors whose terms expire shall
be elected for a term of office to expire at the second succeeding Annual
Meeting of Stockholders after their election. The number of Directors which
shall constitute the whole Board shall not be less than five nor more than nine.
The number of authorized directors shall be initially fixed at seven. Within the
limits above specified, the number of Directors shall be determined by
resolution of the Board of Directors or by the stockholders at the annual
meeting of the stockholders, except as provided in Section 2 of this Article,
and each Director elected shall hold office until his successor is elected and
qualified. Directors need not be stockholders.

        Section 2. Vacancies. Vacancies and newly created Directorships
resulting from any increase in the authorized number of Directors may be filled
by a majority of the Directors then in office, though less than a quorum, or by
a sole remaining Director, and the Directors so chosen shall hold office until
the next annual election and until their successors are duly elected and shall
qualify, unless sooner displaced. If there are no Directors in office, then an
election of Directors may be held in the manner provided by statute. If, at the
time of filling any vacancy or any newly created Directorship, the Directors
then in office shall constitute less than a majority of the whole Board (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding at least ten 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.

        Section 3. Powers. The business of the corporation shall be managed by
or under the direction of its Board of Directors which may exercise all such
powers of the corporation and do all such lawful acts and things as are not by
statute or by the Certificate of Incorporation or by these Bylaws directed or
required to be exercised or done by the stockholders.

                                       -5-
<PAGE>   7
        Section 4. Regular and Special Meetings. The Board of Directors of the
corporation may hold meetings, both regular and special, either within or
without the State of Delaware.

        Section 5. Annual Meeting. 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 and no notice of such meeting shall be
necessary to the newly elected Directors in order legally to constitute the
meeting, provided a quorum shall be present. 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 meetings of the Board of Directors, or as shall be specified in a
written waiver signed by all of the Directors.

        Section 6. Notice of Regular Meetings. Regular meetings of the Board of
Directors may be held without notice at such time and at such place as shall
from time to time be determined by the Board.

        Section 7. Notice of Special Meetings. Special meetings of the Board may
be called by the president on four (4) days' notice to each Director by mail or
48 hours' notice to each Director either personally or by telegram; special
meetings shall be called by the president or secretary in like manner and on
like notice on the written request of two Directors unless the Board consists of
only one Director, in which case special meetings shall be called by the
president or secretary in like manner and on like notice on the written request
of the sole Director.

        Section 8. Quorum. At all meetings of the Board a majority of the
Directors shall constitute a quorum for the transaction of business and the act
of a majority of the Directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the Certificate of Incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
Directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

        Section 9. Action Without Meeting. Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee.

        Section 10. Meetings by Telephone Conference Calls. Unless otherwise
restricted by the Certificate of Incorporation or these Bylaws, members of the
Board of Directors, or any committee designated by the Board of Directors, may
participate in a

                                       -6-
<PAGE>   8
meeting of the Board of Directors, or any committee, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at the meeting.

        Section 11. Committees. The Board of Directors may, by resolution passed
by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the Directors of the corporation. The
Board may designate one or more Directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee.

            In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.

            Any such committee, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the Certificate of Incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the Bylaws of the corporation; and,
unless the resolution or the Certificate of Incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock. Such committee or committees shall have such
name or names as may be determined from time to time by resolution adopted by
the Board of Directors.

their expenses, if any, of attendance at each meeting of the Board of Directors
and may be paid a fixed sum for attendance at each meeting of the Board of
Directors or a stated salary as Director. No such payment shall preclude any
Director from serving the corporation in any other capacity and receiving
compensation therefor. Members of special or standing committees may be allowed
like compensation for attending committee meetings.

        Section 1. Certificates of Stock. Every holder of stock in the
corporation 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,

certifying the number of shares owned by him in the corporation.

paid shares, the total

                                      -10-
<PAGE>   12
amount of the consideration to be paid therefor, and the amount paid thereon
shall be specified.

            If the corporation shall be authorized to issue more than one class
of stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualification, 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 which the corporation shall
issue to represent such class or series of stock, provided 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

certificate or certificates to be issued in place of any certificate or

stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner

        Section 5. Fixing Record Date. In order that the corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholder or any adjournment thereof, or entitled to receive payment of any
dividend or other distribution or allotment of any rights, or 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 be more than sixty (60) nor less than
ten (10) days before the date of such meeting, nor more than sixty (60) days
prior to any other action. 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; provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting.

        Section 6. Registered Stockholders. The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and to hold liable
for calls and assessments a person registered on its books as the owner of
shares and shall not be bound to recognize any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or other notice thereof, except as otherwise provided by
the laws of Delaware.

                                   ARTICLE VII
                                 INDEMNIFICATION

        Section 1. Indemnification of Directors and Executive Officers. The
corporation shall indemnify its Directors and executive officers to the fullest
extent not prohibited by the Delaware General Corporation Law; provided,
however, that the corporation may limit the extent of such indemnification by
individual contracts with its Directors and executive officers; and, provided,
further, that the corporation shall not be required to indemnify any Director or
executive officer in connection with any proceeding or part thereof) initiated
by such person or any proceeding by such person against the corporation or its
Directors, officers, employees or other agents unless (i) such indemnification
is expressly required to be made by law, (ii) the proceeding was authorized by
the Board of Directors of the corporation, (iii) such indemnification is
provided by the corporation, in its sole discretion, pursuant to the powers
vested in the corporation under the Delaware General Corporation Law.

        Section 2. Indemnification of Other Officers. Employees and Other
Agents. The corporation shall have power to indemnify its other officers,
employees and other agents as set forth in the Delaware General Corporation Law.

        Section 3. Good Faith.

            (a) For purposes of any determination under this Bylaw, a Director
or executive officer shall be deemed to have acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, to have had
no reasonable cause to

                                      -12-
<PAGE>   14
believe that his conduct was unlawful, if his action is based on information,
opinions, reports and statements, including financial statements and other
financial data, in each case prepared or presented by:

                 (1) one or more officers or employees of the
            corporation whom the Director or executive officer
            believed to be reliable and competent in the matters
            presented,

                 (2) counsel, independent accountants or other
            persons as to matters which the Director or executive
            officer believed to be within such person's
            professional competence; and

                 (3) with respect to a Director, a committee of
            the Board upon which such Director does not serve, as
            to matters within such Committee's designated
            authority, which committee the Director believes to
            merit confidence; so long as, in each case, the
            Director or executive officer acts without knowledge
            that would cause such reliance to be unwarranted.

            (b) The termination of any proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that the person did not act in good faith
and in a manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal proceeding, that
he had reasonable cause to believe that his consent was unlawful.

            (c) The provisions of this Section 3 shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the Delaware
General Corporation Law.

        Section 4. Expenses. The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any Director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it should be determined ultimately that such person is not entitled
to be indemnified under this Bylaw or otherwise.

            Notwithstanding the foregoing, unless otherwise determined pursuant
to Section 4 of this Bylaw, no advance shall be made by the corporation if a
determination is reasonably and promptly made (i) by the Board of Directors by a
majority vote of a quorum consisting of Directors who were not parties to the
proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a
quorum of disinterested Directors so directs, by independent legal counsel in a
written opinion, that the facts known to the decision-making parry at the time
such determination is made demonstrate clearly and

                                      -13-
<PAGE>   15
convincingly that such person acted in bad faith or in a manner that such person
did not believe to be in or not opposed to the best interests of the
corporation.

        Section 5. Enforcement. Without the necessity of entering into an
express contract, all rights to indemnification and advances to Directors and
executive officers under this Bylaw shall be deemed to be contractual rights and
be effective to the same extent and as if provided for in a contract between the
corporation and the Director or executive officer. Any right to indemnification
or advances granted by this Bylaw to a Director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. The corporation shall be entitled to raise as a
defense to any such action that the claimant has not met the standards of
conduct that make it permissible under the Delaware General Corporation Law for
the corporation to indemnify the claimant for the amount claimed. Neither the
failure of the corporation (including its Board of Directors, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the Delaware General Corporation Law, nor an actual determination by
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

        Section 6. Non-Exclusivity of Rights. The rights conferred on any person
by this Bylaw shall not be exclusive of any other right which such person may
have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office. The corporation is specifically
authorized to enter into individual contracts with any or all of its Directors,
officers, employees or agents respecting indemnification and advances, to the
fullest extent not prohibited by the Delaware General Corporation Law.

        Section 7. Survival of Rights. The rights conferred on any person by
this Bylaw shall continue as to a person who has ceased to be a Director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

        Section 8. Insurance. To the fullest extent permitted by the Delaware
General Corporation Law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Bylaw.

                                      -14-
<PAGE>   16
        Section 9. Amendments. Any repeal or modification of this Bylaw shall
only be prospective and shall not affect the rights under this Bylaw in effect
at the time of the alleged occurrence of any action or omission to act that is
the cause of any proceeding against any agent of the corporation.

        Section 10. Saving Clause. If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each Director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated, or by any other applicable law.

        Section 11. Certain Definitions. For the purposes of this Bylaw, the
following definitions shall apply:

            (a) The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, arbitration and appeal of, and the giving of the testimony
in, any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative.

            (c) The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
Directors, officers, and employees or agents, so that any person who is or was a
Director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a Director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Bylaw with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued.

            (d) References to a "Director," "officer," "employee," or "agent" of
the corporation shall include, without limitation, situations where such person
is serving at the request of the corporation as a Director, officer, employee,

<PAGE>   17
employee, or agent with respect to an employee benefit plan, its participants,
or beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this Bylaw.

                                  ARTICLE VIII

        Section 1. 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 of its subsidiaries, including any officer or employee who
is a Director of the Corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation. The loan, guarantee or other assistance may
be with or 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 in this bylaw shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

                                   ARTICLE IX

be set aside out of any funds of the corporation available for dividends such
sum or sums as the Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the corporation, or
for such other purposes as the Directors shall think conducive to the interest
of the corporation, and the Directors may modify or abolish any such reserve in
the manner in which it was created.

        Section 3. Execution of Corporate Instruments. All checks or demands for

audit from the books and records of the corporation. When there are more than
100 stockholders of record of the corporation's shares, as determined by Section
605 of the California Corporations Code, additional information as required by
Section 1501(b) of the California Corporations Code shall also be contained in
such report, provided that if the corporation has a class of securities
registered under Section 12 of the 1934 Act, that Act shall take precedence.
Such report shall be sent to stockholders at least fifteen (15) days prior to
the next annual meeting of stockholders after the end of the fiscal year to

            (b) If and so long as there are fewer than 100 holders of record of
the corporation's shares, the requirement of sending of an annual report to the
stockholders of the corporation is hereby expressly waived.

<PAGE>   2
                VOTING AGREEMENT AND IRREVOCABLE PROXY

        This Voting Agreement And Irrevocable Proxy (the "Agreement") is made
and entered into as of the 24th day of May, 1996 by and among Baxter Healthcare
Corporation, a Delaware corporation ("Baxter") and Maxal Capital Corporation, a
New York corporation ("Maxal").

        WHEREAS, pursuant to the terms and conditions of an Agreement and Plan
of Reorganization of even date herewith, Ixion, Inc., a Delaware corporation
(of which Maxal is the majority stockholder) is being merged (the "Merger")
with and into Medical Media Systems, Inc. ("MMS"), a Delaware corporation (of
which Baxter is the majority stockholder) after which the name of MMS shall
be changed to Interact Medical Technologies Corporation ("Interact");

        WHEREAS, subsequent to the Merger, Maxal and Baxter shall be
stockholders of Interact and Maxal shall own, of record and beneficially,
695,030 shares of Interact common stock (the "Shares"); and

        WHEREAS, the parties desire to provide for a voting agreement upon the
terms and subject to the conditions set forth herein.

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants and agreements herein contained and other good and valuable
consideration, the receipt and sufficiency of which is acknowledged, the
parties hereto hereby agree as follows:

        1.   Agreement to Vote and Irrevocable Proxy.

        1.1  Agreement to Vote.  Maxal hereby agrees that at any meeting of the
stockholders of Interact, however called, and in any action by written consent
of the stockholders of Interact, Maxal shall vote all its Shares in such a
manner as to elect one director nominated by Baxter.

        1.2  Irrevocable Proxy.  Maxal hereby constitutes and appoints Baxter
which shall act by and through Stuart Foster or Jay P. Wertheim (each, a "Proxy
Holder"), and each of them, with full power of substitution, its true and
lawful proxy and attorney-in-fact to vote at any and all meetings of the
stockholders of Interact, whether annual or special, and at any adjournment or
adjournments or postponements of any such meetings, and to execute and deliver 
any written consent of stockholders in lieu of any such meeting, all Shares 
which Maxal beneficially owns as of the date of any such meeting or written 
consent, in such manner as Baxter sees fit in the exercise of its sole 
discretion. Notwithstanding the foregoing, such proxy shall be limited 
strictly to the power to vote such Shares in the manner set forth in 
Section 1.1 hereof and shall not extend to any other matters.

        The proxy and power of attorney granted herein shall be irrevocable
during the term of this Agreement, shall be deemed to be coupled with an
interest sufficient in law to support an irrevocable proxy and shall revoke all
prior proxies granted by Maxal, which in any way conflicts herewith. Maxal
shall not grant any proxy to any person which conflicts with the proxy granted
herein, and any attempt to do so shall be void. The power of attorney granted
herein is a durable power of attorney and shall survive the disability or
incompetence of any representative of Maxal.
<PAGE>   3
        In the event that Maxal fails for any reason to vote its Shares in
accordance with the requirements of Section 1.1 hereof, then the Proxy Holder
shall have the right to vote such shares at any meeting of the Interact
stockholders and in any action by written consent of the Interact stockholders
in accordance with the provisions of this Section 1.2. The vote of the Proxy
Holder shall control in any conflict between his vote of such Shares and a vote
by Maxal of such Shares.

        2.  Representations and Warranties of Maxal.  Maxal represents and
warrants to Baxter as follows:

        2.1  Ownership of Shares.  The Shares are owned of record and
beneficially by Maxal, free and clear of all liens or encumbrances, and
constitute all the shares of common stock of Interact owned of record and
beneficially by Maxal.

        2.2  Power; Binding Agreement.  Maxal has full legal right, power and
authority to enter into and perform all of its obligations under this
Agreement. The execution and delivery of this Agreement by Maxal, and the
consummation of the transactions contemplated hereby will not violate any other
agreement to which Maxal is a party including, without limitation, any voting
agreement, stockholders' agreement or voting trust. This Agreement has been
duly executed and delivered by Maxal and constitutes a legal, valid and binding
agreement of Maxal, enforceable in accordance with its terms to the fullest
extent permitted by law.

        3.  Covenants of Maxal. Maxal agrees, while this Agreement is in
effect, to:

        (a)  not sell, exchange, transfer, pledge, encumber, assign or
otherwise dispose of, or enter into any contract, option or other arrangement
or understanding with respect to the sale, exchange, transfer, pledge,
encumbrance, assignment or other disposition of, any Shares unless the
transferee of such Shares shall agree to be bound by the terms and provisions
of this Agreement; and

        (b) use its best efforts to cause Interact to provide reasonable
notice to Baxter of all meetings of Interact's board of directors, to afford a
designee of Baxter the right to attend all such meetings and to provide Baxter
with copies of the minutes of such meetings within a reasonable period after
each such meeting.

        4.  Termination.  This Agreement shall terminate on the closing date of
Interact's initial public offering on a registration statement on Form S-1
which results in gross offering proceeds of at least $10 million.

        5.  Successors and Assigns.  Except as otherwise provided herein, the
provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto. 

        6.  Legend.  Each certificate for Shares shall bear a legend stating in
substance as follows, and Maxal shall cause its certificates to be so legended
promptly after the execution of this Agreement:

        "The rights of the holder of these shares are subject to the terms and
        provisions of a certain Voting Agreement and Irrevocable Proxy dated as
        of May 24, 1996."

        7.  Severability.  The provisions set forth in this Agreement are
severable. If any provision of this Agreement is held invalid or unenforceable
in any jurisdiction, the remainder of this Agreement, and the application of
such provision to other persons or circumstances, shall not be affected
thereby, and shall remain valid and enforceable in such jurisdiction, and any
such invalidity or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

        8.  Injunctive Relief.  The parties agree that in the event of a breach
of any provision of this Agreement, the aggrieved party may be without an
adequate remedy at law. The parties therefore agree that in the event of a
breach of any provision of this Agreement, the aggrieved party may elect to

             3.1 Ordering; Forecasts. Orders of the Product placed by End Users
or Distributor shall be subject to all the terms and conditions of this
Agreement, which shall have precedence over the terms of any purchase order
issued by Distributor or acceptance issued by Supplier, save in respect of
quantities, prices and delivery dates. At least ten (10) days prior to the
beginning of each calendar quarter (the "Applicable Quarter"), Distributor shall
deliver to Supplier a forecast of projected orders for the next twelve month
period. Unless Supplier notifies Distributor in writing of any objections within
ten (10) days of receipt of any such forecast, the forecast for the Applicable
Quarter shall be deemed to be the Delivery Minimum for such Applicable Quarter.
Supplier agrees that it shall meet at least the Delivery Minimum if orders are
placed for such number of Product. Notwithstanding the foregoing, the parties
agree that the Delivery Minimum for any quarter shall be no greater than [one
hundred and ten percent (110%)] of the number of units of Product ordered during
the immediately preceding calendar quarter.

             3.2 Minimum Order Guaranty.

             (a) During the initial twelve months after the Capacity Date (the
"Initial Period"), Distributor will guaranty Supplier that total sales from
orders for the Product for End Users will equal or exceed $350,000. In the event
that total sales to Distributor and End Users during the Initial Period do not
equal or exceed $350,000, Distributor shall, promptly after the expiration of
the Initial Period, pay Supplier 70% of the difference between $350,000 and
total sales for the Initial Period and receive credit for future orders of that
number of Product units equal to the quotient of the amount paid divided by the
average Transfer Price for the previous twelve months (the calculation of such
average Transfer Price shall exclude sales pursuant to Section 3.3(c) hereof).

                                        4
<PAGE>   6
             (b) For each twelve-month period following the Initial Period
(each, a "Contract Year") during the Initial Term of this Agreement, Distributor
shall guaranty Supplier that total sales to Distributor and End Users for each
Contract Year shall equal or exceed the product of 1,000 multiplied by the
average End User Price for the previous Contract Year (or the Initial Period if
calculated during the first Contract Year). In the event that total sales to
Distributor and End Users for any Contract Year do not equal or exceed such
amount, Distributor shall (a) promptly after the expiration of such Contract
Year, pay Supplier 70% of the shortfall and receive credit for future orders of
that number of Product units equal to the quotient of the amount paid divided by
the average Transfer Price for the previous Contract Year (or the Initial Period
if calculated during the first Contract Year) and (b) at Distributor's option,
terminate this Agreement.

             (c) Prior to the expiration of the Initial Term, Supplier and
Distributor shall negotiate in good faith a minimum order guaranty for the
Option Term.

             3.3 Pricing and Commissions.

             (a) The End User Price shall be determined by Distributor based
upon its assessment of End Users and market conditions. Distributor may revise
such prices from time to time.

             (b) With respect to sales by Supplier directly to the End User, the
commission payable by Supplier to Distributor with respect to each Product unit
sold shall be equal to thirty percent (30%) of the End User Price for the first
ten units purchased by a specific End User and twenty-three percent (23%) of the
End User Price for each unit purchased thereafter by such End User.

             (c) With respect to sales by Supplier to Distributor, the purchase
price payable by Distributor to Supplier with respect to each Product unit shall
be equal to the applicable Transfer Price; provided, however, that Distributor
shall have the right to purchase up to 200 units of Product in the Initial
Period and each Contract Year for a purchase price equal to $500 per Product
unit.

             3.4 Payment and Supplier Reports. Commissions shall be payable by
Supplier to Distributor or the purchase price shall be payable by Distributor to
Supplier, as the case may be, within thirty (30) days of the date a Product is
delivered to an End User. Following the end of each fiscal quarter of Supplier,
Supplier shall provide Distributor with a report of the Products sold during
such quarter, which report shall contain the name and address of End Users to
whom Products were sold, the number of Product units sold to each End User and
the End User Price for each Product unit. Distributor shall have the right, at
its expense, to audit the books and records of Supplier to confirm the accuracy
of the report prepared pursuant to this Section 3.4.

             3.5 Delivery Time. Supplier agrees to use its commercially
reasonable efforts to complete a Product ordered by an End User or Distributor
within 72 hours of the receipt by Supplier of the necessary information from the
End User to complete the Product.

Distributor shall:

             (a) Advertise and promote the Products by such methods as in

       Except as disclosed on Schedules 2 or 3 attached hereto, which shall
specifically reference the applicable representations and warranties in this
Agreement (the "Disclosure Schedules"), Borrower represents and warrants to
Lender as follows:

       SECTION 3.01. Organization, Standing and Power. Borrower is a corporation
duly organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Borrower has the corporate power to own its
properties and to carry on its business as now being conducted and as proposed
to be conducted and is duly qualified to do business and is in good standing in
each jurisdiction in which the failure to be so qualified and in good standing
would have a Material Adverse Effect on Borrower. Borrower has delivered a true
and correct copy of its Certificate of Incorporation and Bylaws or other charter
documents, as applicable, each as amended to date, to Lender. Borrower is not in
violation of any of the provisions of its

                                        5
<PAGE>   7
Certificate of Incorporation or Bylaws or equivalent organizational documents.
There are no outstanding subscriptions, options, warrants, puts, calls, rights,
exchangeable or convertible securities or other commitments or agreements of any
character relating to the issued or unissued capital stock, or otherwise
obligating Borrower to issue, transfer, sell, purchase, redeem or otherwise
acquire any such securities. Borrower does not directly or indirectly own any
equity or similar interest in, or any interest convertible or exchangeable or
exercisable for, any equity or similar interest in, any corporation,
partnership, joint venture or other business association or entity.

       SECTION 3.02. Capital Structure. The authorized capital stock of Borrower
consists of 10,000,000 shares of Common Stock, $0.01 par value, of which there
are issued and outstanding 3,133,347 shares. There are no other outstanding
shares of capital stock or voting securities and no outstanding commitments to
issue any shares of capital stock or voting securities other than pursuant to
(i) the exercise of options outstanding as of the date hereof under the Stock
Option Plan and (ii) the Securities. All outstanding shares of Common Stock are
duly authorized, validly issued, fully paid and non-assessable and are free of
any liens or encumbrances other than any liens or encumbrances created by or
imposed upon the holders thereof, and are not subject to preemptive rights or
rights of first refusal created by statute, the Certificate of Incorporation or
Bylaws of Borrower or any agreement to which Borrower is a party or by which it
is bound. Borrower has reserved 237,132 shares of Common Stock for issuance to
employees and consultants pursuant to the Stock Option Plan, of which 3,557
shares have been issued pursuant to option exercises or direct stock purchases,
74,360 shares are subject to outstanding, unexercised options, and no shares are
subject to outstanding stock purchase rights. Except for (i) the rights created
pursuant to this Agreement, (ii) Borrower's right to repurchase any unvested
shares under the Stock Option Plan and (iii) Borrower's obligations to issue
shares of its Common Stock pursuant to the Securities, there are no other
options, warrants, calls, rights, commitments or agreements of any character to
which Borrower is a party or by which it is bound obligating Borrower to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of capital stock of Borrower or obligating
Borrower to grant, extend, accelerate the vesting of, change the price of, or
otherwise amend or enter into any such option, warrant, call, right, commitment
or agreement. There are no contracts, commitments or agreements relating to
voting, purchase or sale of Borrower's capital stock (i) between or among
Borrower and any of its stockholders and (ii) to the best of Borrower's
knowledge, between or among any of Borrower's stockholders. True and complete
copies of all agreements and instruments relating to or issued under the Stock
Option Plan have been made available to Lender and such agreements and
instruments have not been amended, modified or supplemented, and there are no
agreements to amend, modify or supplement such agreements or instruments in any
case from the form made available to Lender.

       SECTION 3.03. Authority. Borrower has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of Borrower. This Agreement has
been duly executed and delivered by Borrower and constitutes the valid and
binding obligation of Borrower enforceable against Borrower in accordance with
its terms. The execution and delivery of this Agreement by Borrower does not,
and the consummation of the

                                        6
<PAGE>   8
transactions contemplated hereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under (i) any provision of the Certificate
of Incorporation or Bylaws of Borrower, or (ii) any material mortgage,
indenture, lease, contract or other agreement or instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance, rule or
regulation applicable to Borrower or any of its properties or assets, except
where such conflict, violation, default, termination, cancellation or
acceleration with respect to the foregoing provisions of (ii) would not have had
and would not reasonably be expected to have a Material Adverse Effect on
Borrower.

       SECTION 3.04. Financial Statements. Borrower has delivered to Lender
audited financial statements for its predecessor entities (balance sheet and
profit and loss statement, statement of stockholders' equity and statement of
changes in financial position) at December 31, 1995, and for the fiscal year
then ended and unaudited financial statements (balance sheet and profit and loss
statement) at and for the 3-month period ended March 31, 1996 (collectively, the
"Financial Statements"). The Financial Statements are complete and correct in
all material respects and have been prepared in accordance with GAAP applied on
a consistent basis throughout the periods indicated and with each other, except
that unaudited Financial Statements may not contain all footnotes required by
GAAP and have not been condensed as required by GAAP. The Financial Statements
accurately set out and describe the financial condition and operating results of
Borrower as of the dates, and for the periods, indicated therein, subject to
normal year-end adjustments. Except as set forth in the Financial Statements,
Borrower has no liabilities, contingent or otherwise, other than (a) liabilities
incurred in the ordinary course of business since March 31,1996, (b) liabilities
set forth on the Disclosure Schedules and (c) obligations under contracts and
commitments incurred in the ordinary course of business and not required under
GAAP to be reflected in the Financial Statements, which, in each case,
individually or in the aggregate, are not material to the financial condition or
operating results of Borrower. Borrower maintains and will continue to maintain
a standard system of accounting established and administered in accordance with
GAAP.

       SECTION 3.05. Absence of Certain Changes. Except for the transactions
contemplated by the Merger Agreement, since March 31,1996, Borrower has
conducted its business in the ordinary course consistent with past practice and
there has not occurred: (i) any change, event or condition (whether or not

result in, a Material Adverse Effect to Borrower; (ii) any acquisition, sale or
transfer of any material asset of Borrower other than in the ordinary course of
business and consistent with past practice; (iii) any change in accounting
methods or practices (including any change in depreciation or amortization
policies or rates) by Borrower or any revaluation by Borrower of any of its
assets; (iv) any declaration, setting aside, or payment of a dividend or other
distribution with respect to the shares of Borrower, or any direct or indirect
redemption, purchase or other acquisition by Borrower of any of its shares of
capital stock; (v) any material contract entered into by Borrower, other than in
the ordinary course of business and as provided to Lender, or any material
amendment or termination of, or default under, any material contract to which
Borrower is a party or by which it is bound; or (vi) any negotiation or
agreement by Borrower to do any of the things described in the preceding clauses
(i) through (v) (other than negotiations with Lender and its representatives
regarding the transactions contemplated by this Agreement).

instruments to which Borrower is a party, which involve future revenue to or
payments by Borrower that are material, are listed in the Disclosure Schedule
(collectively, the "Material Contracts"). Except as set forth in the Disclosure
Schedule, all the Material Contracts are in full force and effect in all
material respects. Borrower has no notice that any party to any such Material
Contract intends to cancel, withdraw, modify or amend such Material Contract.
Borrower is not in material default or breach, and no event has occurred or will
occur by reason of the transactions contemplated in this Agreement which would
constitute a default or breach, where such default or breach would entitle
another party to this Agreement to accelerate or terminate such Material
Contract or otherwise impose a material penalty or forfeiture thereunder
(whether with or without notice, lapse of time or the happening or occurrence of
any other event), under any Material Contract.

       SECTION 3.09. Litigation. There is no private or governmental action,
suit, proceeding, claim, arbitration or investigation pending before any agency,
court or tribunal, foreign or domestic, or, to the knowledge of Borrower

could reasonably be expected to have a Material Adverse Effect on Borrower.

Borrower any of its respective directors or officers (in their capacities as

expected to have a Material Adverse Effect on Borrower.

any such interest ((i) and (ii) herein collectively called "Authorizations"),
and all of such

                                        8
<PAGE>   10

or have any of such Authorizations could not reasonably be expected to have a
Material Adverse Effect on Borrower.

of its properties, interests in properties and assets, real and personal,
reflected in the Financial Statements or acquired after March 31, 1996 (except

comply with Environmental Health and Safety laws; and (ix) Borrower has all
environmental health and safety permits and licenses required to be issued and
is in compliance with the terms and conditions of those permits.

       SECTION 3.15. Taxes. Borrower and any consolidated, combined, unitary or
aggregate group for Tax purposes of which Borrower has been a member have timely
filed all Tax Returns required to be filed by it, have paid all Taxes shown
thereon to be due and has provided adequate accruals in accordance with GAAP in
its financial statements for any Taxes that have not been paid, whether or not
shown as being due on any Tax Returns. No material claim for Taxes has become a
lien against the property of Borrower or is being asserted against Borrower
other than liens for Taxes not yet due and payable. No audit of any Tax Return
of Borrower is being conducted by a Tax authority. No extension of the statute
of limitations on the assessment of any Taxes has been granted by Borrower and
is currently in effect. There is no agreement, contract or arrangement to which
Borrower is a party that may result in the payment of any amount that would not
be deductible by reason of Sections 280G, 162 or 404 of the Code. Borrower is
not a party to any tax sharing or tax allocation agreement nor does Borrower owe
any amount under any such agreement. Borrower is in full compliance with all
terms and conditions of any Tax exemptions or other Tax-sparing agreement or
order of a foreign government.

       SECTION 3.16. Employee Benefit Plans.

             (a) Schedule 3.16 attached hereto lists, with respect to Borrower
and any trade or business (whether or not incorporated) which is treated as a
single employer with Borrower (an "ERISA Affiliate") within the meaning of
Section 414(b), (c), (m) or (o) of the Code, (i) all material employee benefit
plans (as defined in Section 3(3) of the Employee Retirement Income Security Act
of 1974, as amended ("ERISA")), (ii) each loan to a non-officer employee in
excess of $50,000, loans to officers and directors and any stock option, stock
purchase, phantom stock, stock appreciation right, supplemental retirement,
severance, sabbatical, medical, dental, vision care, disability, employee
relocation, cafeteria benefit (Code section 125) or dependent care (Code Section
129), life insurance or accident insurance plans, programs or arrangements,
(iii) all bonus, pension, profit sharing, savings, deferred compensation or
incentive plans, programs or arrangements, (iv) other fringe or employee benefit
plans, programs or arrangements that apply to senior management of Borrower and
that do not generally apply to all employees, and (v) any current or former
employment or executive compensation or severance agreements, written or
otherwise, as to which unsatisfied obligations of Borrower of greater than
$50,000 remain for the benefit of, or relating to, any present or former
employee, consultant or director of Borrower (together, the "Employee Plans").

             (b) Borrower has furnished to Lender a copy of each of the Employee
Plans and related plan documents (including trust documents, insurance policies
or contracts, employee booklets, summary plan descriptions and other authorizing
documents, and, to the extent still in its possession, any material employee
communications relating thereto) and has, with respect to each Employee Plan
which is subject to ERISA reporting requirements, provided copies of the Form
5500 reports filed for the last three plan years. Any Employee Plan intended to
be qualified under Section 401(a) of the Code has either obtained from the
Internal Revenue Service a favorable determination letter as to its qualified
status under the Code, including all amendments to the Code effected by the Tax
Reform Act of 1986 and subsequent legislation, or has applied to the Internal
Revenue Service for such a determination letter prior to the expiration of the
requisite period under applicable Treasury Regulations or Internal Revenue
Service pronouncements in which to apply for such determination letter and to
make any amendments necessary to obtain a favorable determination. Borrower has
also furnished Lender with the most recent Internal Revenue Service
determination letter issued with respect to each such Employee Plan, and nothing
has occurred since the issuance of each such letter which could reasonably be
expected to cause the loss of the tax-qualified status of any Employee Plan
subject to Code Section 401(a).

             (c) (i) None of the Employee Plans promises or provides retiree
medical or other retiree welfare benefits to any person; (ii) there has been no
"prohibited transaction," as such term is defined in Section 406 of ERISA and
Section 4975 of the Code, with respect to any Employee Plan, which could
reasonably be expected to have, in the aggregate, a Material Adverse Effect;
(iii) each Employee Plan has been administered in accordance with its terms and
in compliance with the requirements prescribed by any and all statutes, rules
and regulations (including ERISA and the Code), except as would not have, in the
aggregate, a Material Adverse Effect, and Borrower and each ERISA Affiliate have
performed all obligations required to be performed by them under, are not in any
respect in default under or violation of, and have no knowledge of any default
or violation by any other party to, any of the Employee Plans, which

                                       12
<PAGE>   14
default or violation could reasonably be expected to have a Material Adverse
Effect on Borrower; (iv) neither Borrower nor any ERISA Affiliate is subject to
any liability or penalty under Sections 4976 through 4980 of the Code or Title I
of ERISA with respect to any of the Employee Plans; (v) all material
contributions required to be made by Borrower or any ERISA Affiliate to any
Employee Plan have been made on or before their due dates and a reasonable
amount has been accrued for contributions to each Employee Plan for the current
plan years; (vi) with respect to each Employee Plan, no "reportable event"
within the meaning of Section 4043 of ERISA (excluding any such event for which
the thirty (30) day notice requirement has been waived under the regulations to
Section 4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 or
ERISA has occurred; and (vii) no Employee Plan is covered by, and neither
Borrower nor any ERISA Affiliate has incurred or expects to incur any liability
under Title IV of ERISA or Section 412 of the Code. With respect to each
Employee Plan subject to ERISA as either an employee pension plan within the
meaning of Section 3(2) of ERISA or an employee welfare benefit plan within the
meaning of Section 3(1) of ERISA, Borrower has prepared in good faith and timely
filed all requisite governmental reports (which were true and correct as of the
date filed) and has properly and timely filed and distributed or posted all
notices and reports to employees required to be filed, distributed or posted
with respect to each such Employee Plan. No suit, administrative proceeding,
action or other litigation has been brought, or to the best knowledge of
Borrower is threatened, against or with respect to any such Employee Plan,
including any audit or inquiry by the IRS or United States Department of Labor.
Neither Borrower nor any ERISA Affiliate is a party to, or has made any
contribution to or otherwise incurred any obligation under, any "multiemployer
plan" as defined in Section 3(37) of ERISA

             (d) With respect to each Employee Plan, Borrower has complied with
(i) the applicable health care continuation and notice provisions of COBRA and
the proposed regulations thereunder and (ii) the applicable requirements of the
Family Leave Act of 1993 and the regulations thereunder, except to the extent
that such failure to comply would not, in the aggregate, have a Material Adverse
Effect.

             (e) The consummation of the transactions contemplated by this
Agreement will not (i) entitle any current or former employee or other service
provider of Borrower, or any ERISA Affiliate to severance benefits or any other
payment, except as expressly provided in this Agreement, or (ii) accelerate the
time of payment or vesting, or increase the amount of compensation due any such
employee or service provider.

             (f) There has been no amendment to, written interpretation or
announcement (whether or not written) by Borrower, or any ERISA Affiliate
relating to, or change in participation or coverage under, any Employee Plan
which would materially increase the expense of maintaining such Plan above the
level of expense incurred with respect to that Plan for the most recent fiscal
year included in the Financial Statements.

       SECTION 3.17. Employee Matters. Borrower is in compliance in all respects
with all currently applicable laws and regulations respecting employment,
discrimination in employment, terms and conditions of employment, wages, hours
and occupational safety and health and employment practices, and is not engaged
in any unfair labor practice, except where the failure to be in compliance or
the engagement in such unfair labor practices would not have a Material

                                       13
<PAGE>   15
Adverse Effect on Borrower. There are no pending claims against Borrower under
any workers compensation plan or policy or for long term disability. Borrower
has not incurred any obligations under COBRA with respect to any former
employees or qualifying beneficiaries thereunder, except for obligations that
would not have a Material Adverse Effect on Borrower. There are no controversies
pending or, to the knowledge of Borrower, threatened, between Borrower and any
of its respective employees, which controversies have or could reasonably be
expected to have a Material Adverse Effect on Borrower. Borrower is not a party
to any collective bargaining agreement or other labor unions contract nor does
Borrower know of any activities or proceedings of any labor union to organize
any such employees.

       SECTION 3.18. Interested Party Transactions. Borrower is not indebted to
any director, officer, employee or agent of Borrower (except for amounts due as
normal salaries and bonuses and in reimbursement of ordinary expenses), and no
such person is indebted to Borrower.

       SECTION 3.19. Insurance. Borrower has policies of insurance and bonds of
the type and in amounts customarily carried by persons conducting businesses or
owning assets similar to those of Borrower. There is no material claim pending
under any of such policies or bonds as to which coverage has been questioned,
denied or disputed by the underwriters of such policies or bonds. All premiums
due and payable under all such policies and bonds have been paid and Borrower is
otherwise in compliance in all material respects with the terms of such policies
and bonds. Borrower has no knowledge of any threatened termination of, or
material premium increase with respect to, any of such policies.

       SECTION 3.20. Compliance With Laws. Borrower has complied with, is not in
violation of, and has not received any notices of violation with respect to, any
federal, state, local or foreign statute, law or regulation with respect to the
conduct of its business, or the ownership or operation of its business, except
for such violations or failures to comply as could not be reasonably expected to
have a Material Adverse Effect on Borrower.

       SECTION 3.21. Minute Book. The minute book of Borrower made available to
Lender contains a complete and accurate summary of all meetings of directors and
stockholders or actions by written consent since the time of incorporation of
Borrower through the date of this Agreement, and reflects all transactions
referred to in such minutes accurately in all material respects.

       SECTION 3.22. Complete Copies of Materials. Borrower has delivered or
made available true and complete copies of each document identified on the
Borrower Disclosure Schedule.

       SECTION 3.23. Board Approval. The Board of Directors of Borrower has
unanimously approved this Agreement and the borrowing contemplated hereunder.

       SECTION 3.24. Representations Complete. None of the representations or
warranties made by Borrower herein or in any Schedule hereto, including the
Disclosure Schedule, or certificate furnished by Borrower pursuant to this
Agreement, when all such documents are read together in their entirety, contains
or will contain at the Effective Date any untrue statement of a

                                       14
<PAGE>   16
material fact, or omits or will omit at the Effective Date to state any material
fact necessary in order to make the statements contained herein or therein, in
the light of the circumstances under which made, not misleading.

                                   ARTICLE IV
                                    COVENANTS

to be paid to the holder hereof for the use, forbearance or detention of the
money to be advanced hereunder exceed the highest lawful rate permissible under
applicable usury laws. If, from any circumstances whatsoever, fulfillment of any
provision hereof, at the time performance of such provision shall be due, shall
involve transcending the limit of validity prescribed by law which a court of
competent jurisdiction may deem applicable hereto, then ipso facto, the
obligations to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstances the holder hereof shall ever receive as interest an
amount which would exceed the highest lawful rate, such amount which would be
excessive interest shall be applied to the reduction of the unpaid principal
balance due hereunder and not to the payment of interest.

       Borrower promises to pay all the cost and expenses, including reasonable
attorneys' fees, incurred in the collection and enforcement of this Promissory
Note. Borrower and each surety, endorser, guarantor, and other party ever liable
for payment of any sums of money payable under this Promissory Note, hereby,
jointly and severally, consent to renewal and extension of time at or after the
maturity hereof, without notice, and hereby, jointly and severally waive
diligence, presentment, protest, demand and notice of every kind and, to the
full extent permitted by law, the right to plead any statute of limitations as a
defense to any demand hereunder.

       Set forth below are the exceptions made to the representations and
warranties of Medical Media Systems, Inc. ("MMS") in the Agreement and Plan of
Reorganization dated as of May 24, 1996 (the "Agreement"), by and among Ixion,
Inc. ("Ixion") and MMS (the "Disclosure Schedule").

       Except as otherwise stated, all capitalized terms used herein shall have
the meanings given them in the Agreement. Section numbers used herein correspond
to the Section numbers in the Agreement. Any matter specifically described and
set forth herein as an exception to a Section of the Agreement or specifically
described and set forth in a Schedule to this Agreement shall be deemed to
constitute an exception (to the extent specifically described) to all other
applicable Sections of the Agreement. Where the terms of a contract or other
disclosure item have been summarized or described in this Disclosure Schedule,
such summary or description does not purport to be a complete statement of the
material terms of such contract or other item.

       Nothing herein constitutes an admission of any liability or obligation of
MMS nor an admission against the interest of MMS. The inclusion of anything in
any section of the Disclosure Schedule should not be interpreted as indicating
that MMS has determined that such an agreement or other matter is necessarily

       Group a fee should a merger be consummated between Ixion and MMS. Baxter
       has agreed that it shall be responsible for the fee to be paid to the
       Kriegsman Group, if any.

       consulting services and does not believe that it is obligated to make
       payments to MG as a result of the termination of consulting services.

       know how Cohr Inc. will proceed in this matter.

4.     Multimedia Medical Systems, Inc. and the terms "MMS" and/or "MMMS". MMS
       recently learned of the existence of a company called Multimedia Medical
       Systems, Inc. MMS also understands that this company may be using the
       term "MMS" and/or "MMMS" in connection with its business. It is believed
       that this company may be offering clinical visualization products
       designed to build three dimensional medical images on desktop computers.

       possible use of the terms "MMS" and/or "MMMS", will impact MMS.

       PREVIEW: SURGERY PLANING SOFTWARE product using the MacIntosh version of
       Microsoft's Reality Labs (RL) software product. This is being done on the
       oral and E-mail understanding that Microsoft is granting MMS a
       royalty-free license to use this software. However, MMS has not yet
       received the signed written license agreement from Microsoft. MMS
       understands that it will receive a signed written license agreement for
       this software as soon as the license agreement has been prepared by the
       Microsoft legal department.

8.     Bucholz Patent. Last year a vendor, IGT/Pixsys, suggested to MMS that MMS
       might need to acquire a license under U.S. Patent No. 5,383,454 issued to
       Bucholz, depending on whether certain products were developed by MMS.
       Some preliminary work was done to review this patent, but this work was
       set aside as product emphasis evolved. MMS does not know how the
       existence of the Bucholz patent might impact its products in the future.

       Patent No. 5,005,559 issued to Blanco et. al. Some preliminary work was
       done to review this patent, but this work was set aside as product
       emphasis evolved. MMS does not know how the existence of the Blanco et
       al. patent might impact its products in the future.

10.    General Electric Patents. MMS understands that the General Electric
       Company may own one or more patents relating to modeling processes
       similar to those used by MMS in connection with its PREVIEW products. MMS
       does not know how the existence of any such patents might impact its
       products in the future.

11.    Finnegan. Henderson Patent Infringement Concerns. In the course of
       conducting its due diligence review, the law firm of Finnegan, Henderson
       identified six (6) patents it believed might be infringed by products of
       MMS. These patents are U.S. Patents Nos. 4,882,679 issued to Tuy et al.;
       4,945,478 issued to Merickel et al.; 5,151,856 issued to Halmann et al.;

       company Cemax may be using the term "Preview Mode" and/or "preview mode"
       in connection with one of its products. MMS does not know how Cemax's use
       of the term "Preview mode" and/or "preview mode" might impact MMS.

13.    Preexisting MIT Media Lab Software. Certain of the software developed by
       MMS utilizes preexisting software which was developed earlier at the MIT
       Media Lab by a founder of MMS. MMS understands that this preexisting MIT
       Media Lab software has been placed into the public domain by the MIT
       Media Lab, so that no license is needed to utilize this software.

                               MATERIAL CONTRACTS

1.     Research, Option and License Agreement dated April 8, 1992 between Ixion
       and Ethicon Endo-Surgery ("Ethicon"), a division of Ethicon, Inc., a
       subsidiary of Johnson & Johnson Corporation (the "Ethicon Agreement"),

       to make, have made, use, lease and sell or otherwise dispose of Ixion
       products relating to the use of Ixion technology in the Field defined in
       the Ethicon Agreement as "methods, processes, devices, and instruments
       for the simulation of endoscopic and minimally invasive surgery in humans
       through an extendable, multi-plane computer-based video laparoscopic
       surgical training apparatus with tactile feedback for the teaching of
       surgical skills."

       In September, 1995, Ethicon informed the Company that it believes it has
       certain rights beyond its license to the laparoscopic simulator. The
       Company believes there is no basis to support this position under the

       tendered to Ixion the $100,000 minimum royalty payment for the past
       Royalty Year (as defined in the Ethicon Agreement). Pursuant to Section
       5.5.1 of the Ethicon Agreement, on          ,1996 (the "Delivery Date"),
       Ixion delivered notice of Ixion's intention to convert Ethicon's
       exclusive license into a non-exclusive license. Ethicon has ninety (90)
       from the delivery date to make up any deficiencies in the minimum royalty
       payment for the past Royalty Year (as defined in the last Ethicon
       Agreement) to maintain its exclusive license as described above.

                   processes, devices, and instruments for the simulation of
                   endoscopic and minimally invasive surgery in humans through
                   an extendable, multi-plane computer-based video laparoscopic
                   surgical training apparatus with tactile feedback for the
                   teaching of surgical skills."

                   In September, 1995, Ethicon informed the Company that it
                   believes it has certain rights beyond its license to the
                   laparoscopic simulator. The Company believes there is no
                   basis to support this position under the terms of the Ethicon
                   Agreement as set forth above. Ixion is entitled to receive
                   continuing royalty payments pursuant to the Ethicon
                   Agreement.

$2,000,000                                                       May 24, 1996
                                                              Irvine, California

      FOR VALUE RECEIVED, the undersigned, Interact Medical Technologies
Corporation, a Delaware corporation ("Borrower"), hereby promises to pay to the
order of Baxter Healthcare Corporation, a Delaware corporation ("Lender"), the
principal sum of Two Million Dollars ($2,000,000), together with interest at the
reference rate of Bank of America plus two percent ("Note Rate") on the unpaid
principal from the date hereof until the principal amount of this Promissory
Note is paid in full in accordance with the terms of this Promissory Note. The
principal of this Promissory Note, together with all accrued interest, shall
become due and payable upon the earlier to occur of (i) September 1, 1996 (or
such later date as specifically provided below) or (ii) the closing date of any
registration statement of Borrower on Form S-1 declared effective by the SEC
(the "Registration Statement") for its initial public offering (the "IPO").

      In the event that the IPO does not occur on or prior to September 1, 1996,
then the principal amount, together with all accrued interest, shall be
immediately due and payable on such date; provided, however, that Borrower may
extend this date to September 1, 1997 in exchange for the issuance on September
1, 1996 by Borrower to Lender of shares of Borrower's Common Stock, without
further consideration, at the rate of 2,439 shares for each $25,000 principal
amount outstanding under this Promissory Note. If the closing date for the
Borrower's IPO occurs before September l, 1996, then immediately following such
closing the principal amount, together with all accrued interest, shall be
converted into Common Stock at the price to the public for shares of Common
Stock issued in the IPO as stated in the Registration Statement (the "IPO
Price"). The number of shares of Common Stock into which this Note may be
converted shall be determined by dividing the aggregate principal amount
together with all accrued interest to the date of conversion by the IPO Price.
No fractional shares of Common Stock shall be issued upon conversion of this
Note. In lieu of the Borrower issuing any fractional shares to Lender upon the
conversion of this Note, Borrower shall pay to Lender in cash the amount of the
outstanding principal and accrued interest that is not so converted.

      In the event that any principal and/or interest is not paid when due,
without affecting any of Lender's other rights and remedies, the unpaid
principal amount and, to the extent permitted by applicable law, interest, shall
bear interest at the Note Rate and shall be payable on demand of Lender until
such unpaid amount is paid in full.

      Principal and interest shall be payable in lawful money of the United
States at Lender's offices located at the address for notice purposes set forth
in the Credit Agreement (as defined below).

      This Promissory Note may not be prepaid at any time by the Borrower
without the written consent of Lender.

      This Promissory Note is the Note referred to in, and is entitled to the
benefits of, and is subject to the terms and conditions of, a Credit Agreement
dated as of the date hereof between the Lender and the Borrower as the same may
from time to time be amended, modified or supplemented ("Credit Agreement"), the
terms of which are incorporated herein by reference. Unless the context
indicates otherwise, the capitalized terms appearing in this Note shall have the
meanings designated in the Credit Agreement. The Credit Agreement provides,
among other things, that upon the occurrence of an Event of Default, the Lender
may, among other things,
<PAGE>   70
declare the entire principal amount of this Promissory Note and all accrued
interest thereon immediately due and payable.

      By acceptance of this Promissory Note, Lender represents to the Borrower
that by reason of its business and financial experience it has the capacity to
protect its own interests in this transaction and is accepting this Promissory
Note and any Common Stock issued upon conversion hereof or in connection
herewith, for its own account and not with a view to distribution or resale.

      This Promissory Note shall be governed by, and construed and enforced in
accordance with, the internal laws (excluding the laws of conflict) of the State
of California.

      All agreements between the undersigned and the holder hereof are expressly
limited so that in no contingency or event whatsoever, whether by reason of
advancement of the proceeds hereof, acceleration of maturity of the unpaid
principal balance hereof, or otherwise, shall the amount paid or agreed to be
paid to the holder hereof for the use, forbearance or detention of the money to
be advanced hereunder exceed the highest lawful rate permissible under
applicable usury laws. If, from any circumstances whatsoever, fulfillment of any
provision hereof, at the time performance of such provision shall be due, shall
involve transcending the limit of validity prescribed by law which a court of
competent jurisdiction may deem applicable hereto, then ipso facto, the
obligations to be fulfilled shall be reduced to the limit of such validity, and
if from any circumstances the holder hereof shall ever receive as interest an
amount which would exceed the highest lawful rate, such amount which would be
excessive interest shall be applied to the reduction of the unpaid principal
balance due hereunder and not to the payment of interest.

      Borrower promises to pay all the cost and expenses, including reasonable
attorneys' fees, incurred in the collection and enforcement of this Promissory
Note. Borrower and each surety, endorser, guarantor, and other party ever liable
for payment of any sums of money payable under this Promissory Note, hereby,
jointly and severally, consent to renewal and extension of time at or after the
maturity hereof, without notice, and hereby, jointly and severally waive
diligence, presentment, protest, demand and notice of every kind and, to the
full extent permitted by law, the right to plead any statute of limitations as a
defense to any demand hereunder.

      2. Registration Rights. The Company covenants and agrees as follows:

         2.1 Definitions. For purposes of this Agreement:

             (a) The term "Act" means the Securities Act of 1933, as amended.

             (b) The term "Form S-3" means such form under the Act as in effect
on the date hereof or any registration form under the Act subsequently adopted
by the SEC which permits inclusion or incorporation of substantial information
by reference to other documents filed by the Company with the SEC.

             (c) The term "Holder" means any person owning or having the right
to acquire Registrable Securities or any assignee thereof in accordance with
Section 2.13 hereof.

             (d) The term "1934 Act" shall mean the Securities Exchange Act of
1934, as amended.

             (e) The term "register", "registered" and "registration" refer to a

                                       2.


<PAGE>   6




             (g) The term "SEC" shall mean the Securities and Exchange
Commission.

         2.2 Request for Registration.

             (a) If the Company shall receive at any time after one (1) year
after the effective date of the first registration statement for a public
offering of securities of the Company (other than a registration statement
relating either to the sale of securities to employees of the Company pursuant
to a stock option, stock purchase or similar plan or an SEC Rule 145
transaction), a written request from the Holders of the Registrable Securities
then outstanding that the Company file a registration statement under the Act
covering the registration of at least forty percent (40%) of the Registrable
Securities then outstanding (or a lesser percent if the anticipated aggregate
offering price, net of underwriting discounts and commissions, would exceed
$5,000,000), then the Company shall:

                 (i)  within ten (10) days of the receipt thereof, give written
notice of such request to all Holders; and

                 (ii) effect as soon as practicable, and in any event within
one hundred twenty (120) days of the receipt of such request, the registration
under the Act of all Registrable Securities which the Holders request to be
registered, subject to the limitations of subsection 2.2(b), within twenty (20)
days of the mailing of such notice by the Company in accordance with Section
3.5.

             (b) If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to subsection 2.2(a) and the Company
shall include such information in the written notice referred to in subsection
2.2(a). The underwriter will be selected by the Company and shall be reasonably
acceptable to a majority in interest of the Initiating Holders. In such event,
the right of any Holder to include his Registrable Securities in such
registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company as
provided in subsection 2.4(e)) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting.
Notwithstanding any other provision of this Section 2.2, if the underwriter
advises the Initiating Holders in writing that marketing factors require a
limitation of the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in
proportion (as

                                       3.


<PAGE>   7




  nearly as practicable) to the amount of Registrable Securities of the Company
  owned by each Holder; provided, however, that the number of shares of
  Registrable Securities to be included in such underwriting shall not be
  reduced unless all other securities are first entirely excluded from the
  underwriting.

                    (c) Notwithstanding the foregoing, if the Company shall
  furnish to Holders requesting a registration statement pursuant to this
  Section 2.2, a certificate signed by the Chief Executive Officer of the
  Company stating that in the good faith judgment of the Board of Directors of
  the Company, it would be seriously detrimental to the Company and its
  stockholders for such registration statement to be filed and it is therefore
  essential to defer the filing of such registration statement, the Company
  shall have the right to defer taking action with respect to such filing for a
  period of not more than one hundred twenty (120) days after receipt of the
  request of the Initiating Holders.

                    (d) In addition, the Company shall not be obligated to
  effect, or to take any action to effect, any registration pursuant to this
  Section 2.2:

                           (i)  After the Company has effected one registration
  pursuant to this Section 2.2 and such registration has been declared or 
  ordered effective;

                           (ii) During the period starting with the date thirty 
  (30) days prior to the Company's good faith estimate of the date of filing of,
  and ending on a date one hundred eighty (180) days after the effective date
  of, a registration subject to Section 2.3 hereof; provided that the Company is
  actively employing in good faith all reasonable efforts to cause such
  registration statement to become effective; or

                           (iii) If the Initiating Holders propose to dispose of
  shares of Registrable Securities that may be immediately registered on Form
  S-3 pursuant to a request made pursuant to Section 2.12 below.

              2.3 Company Registration. If (but without any obligation to do so)
  the Company proposes to register (including for this purpose a registration
  effected by the Company for stockholders other than the Holders) any of its
  stock or other securities under the Act in connection with the public offering
  of such securities solely for cash (other than a registration relating solely
  to the sale of securities to participants in a Company stock plan, a
  registration on any form which does not include substantially the same
  information as would be required to be included in a registration statement
  covering the sale of the Registrable Securities or a registration in which the
  only Common Stock being registered is Common Stock issuable upon conversion of
  debt securities which are also being registered), the Company shall, at such
  time, promptly give each Holder written notice of such registration. Upon the
  written request of each Holder given within twenty (20) days after mailing of
  such notice by the Company in accordance with Section 3.5, the Company shall,
  subject to the provisions of Section 2.8,

                                       4.

                                                                                


<PAGE>   8




cause to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

            2.4 Obligations of the Company. Whenever required under this Section
2 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for a period of up to one hundred twenty
(120) days or until the distribution contemplated in the Registration Statement
has been completed; provided, however, that (i) such 120-day period shall be
extended for a period of time equal to the period the Holder refrains from
selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company; and (ii) in
the case of any registration of Registrable Securities on Form S-3 which are
intended to be offered on a continuous or delayed basis, such 120-day period
shall be extended, if necessary, to keep the registration statement effective
until all such Registrable Securities are sold, provided that Rule 415, or any
successor rule under the Act, permits an offering on a continuous or delayed
basis, and provided further that applicable rules under the Act governing the
obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (I) includes any prospectus required by Section
10(a)(3) of the Act or (II) reflects facts or events representing a material or
fundamental change in the information set forth in the registration statement,
the incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the 1934 Act in the registration statement.

                  (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

                  (c) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                  (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to

                                       5.

                                                                                


<PAGE>   9




qualify to do business or to file a general consent to service of process in any
such states or jurisdictions.

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                  (f) Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

                  (g) Cause all such Registrable Securities registered hereunder
to be listed on each securities exchange on which similar securities issued by
the Company are then listed.

                  (h) Provide a transfer agent and registrar for all Registrable
Securities registered hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such registration.

                  (i) Use its best efforts to furnish, at the request of any
Holder requesting registration of Registrable Securities pursuant to this
Section 2, on the date that such Registrable Securities are delivered to the
underwriters for sale in connection with a registration pursuant to this Section
2, if such securities are being sold through underwriters, or, if such
securities are not being sold through underwriters, on the date that the
registration statement with respect to such securities becomes effective, (i) an
opinion, dated such date, of the counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities and
(ii) a letter dated such date, from the independent certified public accountants
of the Company, in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public offering,
addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities.

            2.5   Furnish Information.

                  (a) It shall be a condition precedent to the obligations of
the Company to take any action pursuant to this Section 2 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such

                                       6.

                                                                                


<PAGE>   10




information regarding itself, the Registrable Securities held by it, and the
intended method of disposition of such securities as shall be required to effect
the registration of such Holder's Registrable Securities.

                  (b) The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.2 or Section 2.12 if, due to the
operation of subsection 2.5(a), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in subsection 2.2(a) or subsection
2.12(b)(2), whichever is applicable.

            2.6 Expenses of Demand Registration. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 2.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel for the selling Holders shall
be borne by the Company; provided, however, that the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to Section 2.2 if the registration request is subsequently withdrawn at the
request of the Holders of a majority of the Registrable Securities to be
registered (in which case all participating Holders shall bear such expenses),
unless the Holders of a majority of the Registrable Securities agree to forfeit
their right to demand registrations pursuant to Section 2.2.

            2.7 Expenses of Company Registration. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 2.3 for each Holder (which right may be assigned as provided
in Section 2.13), including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto and the fees and disbursements of one counsel for the selling Holders
selected by them, but excluding underwriting discounts and commissions relating
to Registrable Securities.

            2.8 Underwriting Requirements. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 2.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by stockholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the

                                       7.

                                                                                


<PAGE>   11




success of the offering, then the Company shall be required to include in the
offering only that number of such securities, including Registrable Securities,
which the underwriters determine in their sole discretion will not jeopardize
the success of the offering (the securities so included to be apportioned pro
rata among the selling stockholders according to the total amount of securities
entitled to be included therein owned by each selling stockholder or in such
other proportions as shall mutually be agreed to by such selling stockholders)
but in no event shall (i) the amount of securities of the selling Holders
included in the offering be reduced below thirty percent (30%) of the total
amount of securities included in such offering, unless such offering is the
initial public offering of the Company's securities in which case the selling
stockholders may be excluded if the underwriters make the determination
described above and no other stockholder's securities are included or (ii)
notwithstanding (i) above, any shares being sold by a stockholder exercising a
demand registration right similar to that granted in Section 2.2 be excluded
from such offering. For purposes of the preceding parenthetical concerning
apportionment, for any selling stockholder which is a Holder of Registrable
Securities and which is a partnership or corporation, the partners, retired
partners and stockholders of such holder, or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling stockholder", and
any pro-rata reduction with respect to such "selling stockholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling stockholder", as defined in
this sentence.

            2.9 Delay of Registration. No Holder shall have any right to obtain
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 2.

            2.10  Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 2:

                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
or the 1934 Act, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto; (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading; or (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act or any
rule or regulation

                                       8.

                                                                                


<PAGE>   12




promulgated under the Act or the 1934 Act; and the Company will pay to each such
Holder, underwriter or controlling person any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 2.10(a) shall not apply to amounts paid
in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person of
such Holder.

                  (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act or the 1934 Act, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereto) arise out of or
are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and each such Holder will pay any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection 2.10(b), in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 2.10(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided, that, in no event shall any
indemnity under this subsection 2.10(b) exceed the gross proceeds from the
offering received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
Section 2.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.10, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to

                                       9.

                                                                                


<PAGE>   13




actual or potential differing interests between such indemnified party and any
other party represented by such counsel in such proceeding. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 2.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
2.10.

                  (d) If the indemnification provided for in this Section 2.10
is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                  (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                  (f) The obligations of the Company and Holders under this
Section 2.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 2, and otherwise. No
indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to the entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation.

            2.11 Reports Under Securities Exchange Act of 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to:

                                       10.

                                                                                


<PAGE>   14




                  (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

                  (c) furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

            2.12 Form S-3 Registration. In case the Company shall receive from
Holders of at least twenty percent (20%) of the currently outstanding
Registrable Securities, a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holders,
the Company will:

                  (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders; and

                  (b) as soon as practicable, effect such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder's
or Holders' Registrable Securities as are specified in such request, together
with all or such portion of the Registrable Securities of any other Holder or
Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this section 2.12: (1) if
Form S-3 is not available for such offering by the Holders; (2) if the Holders,
together with the holders of any other securities of the Company entitled to
inclusion in such registration, propose to sell Registrable Securities and such
other securities (if any) at an aggregate price to the public (net of any
underwriters' discounts or commissions) of less than $500,000; (3) if the
Company shall furnish to the Holders a certificate signed by the President of
the Company stating that in the good faith judgment of the Board of Directors of
the Company, it would be seriously detrimental to the Company and its

                                      11.

                                                                                


<PAGE>   15




stockholders for such Form S-3 Registration to be effected at such time, in
which event the Company shall have the right to defer the filing of the Form S-3
registration statement for a period of not more than one hundred twenty (120)
days after receipt of the request of the Holder or Holders under this Section
2.12; (4) if the Company has, within the twelve (12) month period preceding the
date of such request, already effected two registrations on Form S-3 for the
Holders pursuant to this Section 2.12; or (5) in any particular jurisdiction in
which the Company would be required to qualify to do business or to execute a
general consent to service of process in effecting such registration,
qualification or compliance.

                  (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. All expenses incurred in connection with a
registration requested pursuant to Section 2.12, including (without limitation)
all registration, filing, qualification, printer's and accounting fees and the
reasonable fees and disbursements of counsel for the selling Holder or Holders
and counsel for the Company, but excluding any underwriters' discounts or
commissions associated with Registrable Securities, shall be borne by the
Company. Registrations effected pursuant to this Section 2.12 shall not be
counted as demands for registration or registrations effected pursuant to
Sections 2.2 or 2.3, respectively.

            2.13 Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds at
least 100,000 shares of Registrable Securities (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other
recapitalizations), provided the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.

            2.14 Limitations on Subsequent Registration Rights. From and after
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration filed under Section 2.2 hereof,
unless under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of his securities will not reduce the amount of the Registrable
Securities of the Holders which is included or (b) to make a demand registration
which could result in such registration statement being declared effective prior
to the earlier of

                                       12.

                                                                                


<PAGE>   16




either of the dates set forth in subsection 2.2(a) or within one hundred twenty
(120) days of the effective date of any registration effected pursuant to
Section 2.2.

            2.15 "Market Stand-Off" Agreement. Each Investor hereby agrees that,
during the period of duration specified by the Company and an underwriter of
common stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Act, it shall not, to
the extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except common stock included in such
registration; provided, however, that:

                  (a) such agreement shall not exceed 360 days for the first
such registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

                  (b) such agreement shall not exceed 90 days for any subsequent
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;
and

                  (c) all officers and directors of the Company and all other
persons with registration rights (whether or not pursuant to this Agreement)
enter into similar agreements.

                  In order to enforce the foregoing covenant, the Company may
impose stop-transfer instructions with respect to the Registrable Securities of
each Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period. Notwithstanding the
foregoing, the obligations described in this Section 2.15 shall not apply to a
registration relating solely to employee benefit plans on Form S-8 or similar
forms which may be promulgated in the future, or a registration relating solely
to a SEC Rule 145 transaction on Form S-14 or Form S-15 or similar forms which
may be promulgated in the future.

            2.16 Additional Registration Rights. Notwithstanding anything set
forth in this Section 2, Baxter Healthcare Corporation ("Baxter") shall have a
one-time priority over all other parties to this Agreement to register, in
accordance with the terms and conditions contained in this Section 2, a number
of shares of the Company's common stock which will result in gross proceeds of
up to $2,000,000 (but not less than $1,000,000). Baxter's right to exercise the
additional rights granted in this Section 2.16 shall commence six (6) months
after the effective date of the first registration statement for a public
offering of securities of the Company (other than a registration statement
relating either to the sale of securities to employees of the Company pursuant
to a stock

                                       13.

option, stock purchase or similar plan or an SEC Rule 145 transaction) (the
"Effective Date") and shall expire three (3) years after the Effective Date.

            2.17  Termination of Registration Rights.

                  (a) No Holder shall be entitled to exercise any right provided
for in this Section 2 after three (3) years following the consummation of the
sale of securities pursuant to a registration statement filed by the Company
under the Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (b) In addition, the right of any Holder to request
registration or inclusion in any registration pursuant to Section 2.3 shall
terminate on the closing of the first Company-initiated registered public
offering of Common Stock of the Company if all shares of Registrable Securities
held by such Holder may immediately be sold under Rule 144 during any 90-day
period, or on such date after the closing of the first Company-initiated
registered public offering of Common Stock of the Company as all shares of
Registrable Securities held or entitled to be held upon conversion by such
Holder may immediately be sold under Rule 144 during any 90-day period.

            3.    Miscellaneous.

            3.1 Other Rights. Nothing in this Agreement, express or implied, is
intended to confer upon any party other than the parties hereto any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

            3.2 Governing Law. This Agreement shall be governed by and construed
under the laws of the State of California as applied to agreements among
California residents entered into and to be performed entirely within
California.

            3.3 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

            3.4 Titles and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

            3.5 Notices. Unless otherwise provided, any notice required or

written notice to the other parties.

            3.6 Amendments and Waivers. Any term of this Agreement may be
amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), with the written consent of the Company and the Holders of at
least a majority of the Registrable Securities; provided that this Agreement may
be amended with the consent of the Holders of less than all Registrable
Securities only in a manner which affects all Registrable Securities in the same
fashion. No waivers of or exceptions to any term, condition or provision of this
Agreement, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such term, condition or provision.

            3.7 Severability. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, such provision shall be excluded
from this Agreement and the balance of the Agreement shall be interpreted as if
such provision were so excluded and shall be enforceable in accordance with its
terms.

            3.8 Entire Agreement. This Agreement and the documents referred to
herein constitute the entire agreement among the parties and no party shall be
liable or bound to any other party in any manner by any warranties,
representations, or covenants except as specifically set forth herein or
therein.

<PAGE>   2
                                STOCK AGREEMENT

                  THIS STOCK AGREEMENT (the "Agreement") is made as of May 24,
1996 by and among Medical Media Systems, Inc., a Delaware corporation (the
"Company"), Baxter Medical Media Holdings, Inc., a Delaware corporation and a
wholly-owned subsidiary of Baxter Healthcare Corporation ("Baxter Holdings"),
and MMS Founders Group Limited Partnership, a Delaware limited partnership
("MMSLP"). Baxter Holdings and MMSLP are sometimes hereinafter referred to
collectively as the "Transferors" and individually as a "Transferor," with
reference to the following facts:

                  A. Transferors are the general partners of Medical Media
Systems, a New Hampshire general partnership (the "Partnership"). Baxter
Holdings owns a sixty percent (60%) interest in the Partnership and MMSLP owns a
forty percent (40%) interest in the Partnership (referred to collectively as the
"Partnership Interests").

                  B. The Transferors desire to contribute their respective
Partnership Interests to the Company in exchange for shares of the Common Stock
of the Company, and the Company desires to issue such shares to the Transferors,
all on the terms as set forth below.

         FOR AND IN CONSIDERATION OF THE MUTUAL PROMISES AND COVENANTS
             HEREIN CONTAINED, THE PARTIES HEREBY AGREE AS FOLLOWS:

1.       ISSUANCE OF COMMON STOCK.

                  Subject to and upon the terms and conditions of this
Agreement, concurrent with the execution of this Agreement, the Transferors
shall contribute to the Company their respective Partnership Interests in
exchange for an aggregate of 1,253,333 shares of Common Stock of the Company
(the "Shares"), of which Baxter Holdings shall receive 752,000 Shares and MMSLP
shall receive 501,333 Shares.

2.       SECURITIES LAWS REPRESENTATIONS AND WARRANTIES OF TRANSFERORS.

                  (a) Baxter Holdings hereby confirms that the Shares to be
received by it are being and will be acquired for investment for its own
account, not as a nominee or agent, and not with a view to the sale or
distribution of any part thereof, and that Baxter Holdings has no present
intention of selling, granting any participation in, or otherwise distributing
the same. Baxter Holdings further represents that it has no contract,
undertaking, agreement or arrangement with any person to sell, transfer, or
grant participations to such person or to any third person, with respect to any
of the Shares to be acquired by it.

                  (b) MMSLP hereby confirms that the Shares to be received by it
are and will be acquired for investment for its own account and not with a view
to the sale or distribution of any part thereof except as provided in
subparagraph (f) below.

                  (c) Each Transferor understands and acknowledges that the
Shares will not be registered under the Securities Act of 1933, as amended (the
"Act"), or registered or qualified

under any applicable state, local or foreign securities laws on the grounds that
the issuance of securities contemplated by this Agreement are exempt from
registration and/or qualification pursuant to one or more exemptions under the
Act and/or such applicable state, local or foreign securities laws and that the
Company's reliance upon such exemptions is predicated upon such Transferor's
representations set forth in this Agreement. Each Transferor further understands
and acknowledges that there is no public market for the Shares, there may never
be a public market for the Shares and, even if a market develops for the Shares,
such Transferor may never be able to sell or dispose of the Shares purchased by
it pursuant hereto and that, as a result, it may have to bear the risk of an

Gentlemen:

                  In connection with the proposed distribution by MMS Founders
Group Limited Partnership, a Delaware limited partnership ("MMSLP"), to the
undersigned, a holder of partnership units of MMSLP, of a portion of the shares
of Common Stock ("Common Stock") of Medical Media Systems, Inc., a Delaware
corporation (the "Company"), to be acquired by MMSLP, the undersigned does
hereby represent, warrant and covenant to and with the Company as follows:

                  1. The undersigned hereby confirms that the _________ shares
of Common Stock to be distributed to the undersigned as described above (the
"Shares") will be acquired by the undersigned for investment for his, her or its
own account, not as a nominee or agent, and not with a view to the sale or
distribution of any part thereof, and that the undersigned has no present
intention of selling, granting any participation in, or otherwise distributing
the same. The undersigned further represents that the undersigned has no
contract, undertaking, agreement or arrangement with any person to sell,
transfer, or grant participations to such person or to any third person, with
respect to any of the Shares.

                  2. The undersigned understands and acknowledges that the
Shares will not be registered under the Securities Act of 1933, as amended (the
"Act"), or registered or qualified under any applicable state, local or foreign
securities laws on the grounds that the offering and sale of the Shares to MMSLP
and the subsequent distribution thereof to the undersigned are exempt from
registration and/or qualification pursuant to one or more exemptions under the
Act and/or such applicable state, local or foreign securities laws and that the
Company's reliance upon such exemptions is predicated upon the undersigned's
representations set forth in this letter. The undersigned further understands
and acknowledges that there is no public market for the Shares, there may never
be a public market for the Shares and, even if a market develops for the Shares,
the undersigned may never be able to sell or dispose of the Shares acquired by
him, her or it and that, as a result, the undersigned may have to bear the risk
of an investment in the Shares for a substantial period of time or forever.

                  3. The undersigned understands that the certificate for the
Shares shall bear the following legend:

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
         FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933. THE SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
         REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT."

                  4. The undersigned understands that the certificates
evidencing the Shares, or any transferred shares of Common Stock, shall also
bear any legend which may be required pursuant to any state, local or foreign
law governing such securities or which the Company may otherwise deem
appropriate.

                        Very truly yours,

Gentlemen:

                  In connection with the proposed distribution by MMS Founders
Group Limited Partnership, a Delaware limited partnership ("MMSLP"), to the
undersigned, a holder of partnership units of MMSLP, of a portion of the shares
of Common Stock ("Common Stock") of Medical Media Systems, Inc., a Delaware
corporation (the "Company"), to be acquired by MMSLP, the undersigned does
hereby represent, warrant and covenant to and with the Company as follows:

                  1. The undersigned hereby confirms that the _________ shares
of Common Stock to be distributed to the undersigned as described above (the
"Shares") will be acquired by the undersigned for investment for his, her or its
own account, not as a nominee or agent, and not with a view to the sale or
distribution of any part thereof and that the undersigned has no present
intention of selling, granting any participation in, or otherwise distributing
the same. The undersigned further represents that the undersigned has no
contract, undertaking, agreement or arrangement with any person to sell,
transfer, or grant participations to such person or to any third person, with
respect to any of the Shares.

                  2. The undersigned understands and acknowledges that the
Shares will not be registered under the Securities Act of 1933, as amended (the
"Act"), or registered or qualified under any applicable state, local or foreign
securities laws on the grounds that the offering and sale of the Shares to MMSLP
and the subsequent distribution thereof to the undersigned are exempt from
registration and/or qualification pursuant to one or more exemptions under the
Act and/or such applicable state, local or foreign securities laws and that the
Company's reliance upon such exemptions is predicated upon the undersigned's
representations set forth in this letter. The undersigned further understands
and acknowledges that there is no public market for the Shares, there may never
be a public market for the Shares and, even if a market develops for the Shares,
the undersigned may never be able to sell or dispose of the Shares acquired by
him, her or it and that, as a result, the undersigned may have to bear the risk
of an investment in the Shares for a substantial period of time or forever.

     RE: MMS/Ixion Merger

Gentlemen:

     This letter is written in connection with the proposed incorporation of
Medical Media Systems ("MMS"), a New Hampshire general partnership whose
partners are Baxter Medical Media Holdings, Inc. ("Baxter Holdings") and MMS
Founders Group Limited Partnership ("MMSLP"). It is contemplated that
immediately following such incorporation, Ixion, Inc. ("Ixion") will merge with
and into the newly incorporated successor to MMS (the "Merger"), and the
surviving corporation shall change its name to Interact Medical Technologies
Corporation ("Interact"). As a result of the Merger, Baxter Holdings and MMSLP
shall own, in the aggregate, 40% of the outstanding shares of common stock of
Interact on a fully diluted basis, with the remaining 60% to be owned by the
current shareholders and management of Ixion.

     MMSLP and the undersigned partners of MMSLP hereby confirm that they have
been furnished with such documents and financial information as the undersigned
have deemed necessary or advisable in order to become familiar with the
business, management, financial condition and prospects of Ixion, whose
shareholders and management will control Interact following the Merger. In
addition, the undersigned have been afforded an opportunity to meet with
representatives of Ixion and ask and receive answers to any questions the
undersigned have about the business and affairs of Ixion and management's plans
with respect to the operations of Interact following the Merger. On the basis of
the undersigneds' review of these materials and discussions, and relying upon
the undersigneds' knowledge and experience in financial and business matters,
and not in reliance on any express or implied representation, warranty or
assurance by Baxter Healthcare Corporation or any of its officers, employees,
affiliates, advisors, or agents, the undersigned have evaluated the merits and
risks of the Merger and have determined that they are both willing and able to
undertake the economic and business risks associated with the Merger.

                                    Very truly yours,

2.      PREMISES AND COMMON AREAS LEASED.

        a. Landlord hereby leases to Tenant and Tenant hereby leases from
Landlord, the Premises contained within the suite designated in Subparagraph
1.c. The Premises are, or shall be, improved by Landlord with the Leasehold
improvements described in the Work Letter Agreement, a copy of which is attached
hereto and marked Exhibit "B" and Exhibit "B-1" and incorporated herein by this
reference. It is agreed for the purpose of this Lease, that the Premises have an
area of approximately the number of square feet designated in Subparagraph 1.e.,
situated on the floor(s) designated in Subparagraph 1.e., of that certain office
building located at the address designated in Subparagraph 1.e. (hereinafter
called the "Building"). The Premises exclude the common stairways, stairwells,
accessways and pipes, conduits, wires and appurtenant fixtures serving
exclusively or in common other parts of the Building.

        The parties hereto agree that said letting is upon and subject to the
terms, covenants and conditions herein set forth and Tenant covenants as a
material part of the consideration for this Lease to keep and perform each and
all of said terms, covenants and conditions by it to be kept and performed and
that this Lease is made upon the condition of such performance.

        b. Tenant shall have the nonexclusive right to use, in common with
other tenants in the Building and subject to the Rules and Regulations referred
to in Paragraph 30 below, the following areas appurtenant to the Premises:

        (i) The common entrances, lobbies, rest rooms, elevators, stairways
and accessways, loading docks, ramps, drives and platforms and any passageways
and serviceways thereto, and the common pipes, conduits, wires and appurtenant
equipment serving the Premises, which Landlord shall exercise reasonable
diligence to timely maintain and repair;

        (ii) Common walkways and sidewalks necessary for access to the Building
maintained by Landlord.

        c. Landlord reserves the right from time to time without unreasonable
interference with Tenant's use:

        (i) To install, use, maintain, repair and replace pipes, ducts,
conduits, wires and appurtenant meters and equipment included in the Premises
which are located in the Premises or located elsewhere outside the Premises, and
to expand the Building.

        (ii) To alter or relocate any other common facility.

       
3.      TERM. The Term of this Lease shall be for the period designated in
Subparagraph 1.f., commencing on the Commencement Date and ending on the
expiration of such period, unless the Term hereby demised shall be sooner
terminated as hereinafter provided. Upon commencement of the Term, this Lease
shall be amended to set forth the actual date of commencement and expiration of
the Term.

4.      POSSESSION. Should Landlord tender possession of the Premises to Tenant
prior to the date specified for commencement of the Term hereof, and Tenant
elects to accept such prior tender, such prior occupancy shall be subject to
all the terms, covenants and conditions of this Lease, including the payment 
of rent.

5.      ANNUAL BASIC RENT

        a. Tenant agrees to pay Landlord as Annual Basic Rent for the Premises
the Annual Basic Rent designated in Subparagraph 1.k. (subject to adjustment as
hereinafter provided) in twelve (12) equal monthly installments, each in
advance on the first day of each and every calendar month during the Term,
except that the first month's Rent shall be paid upon execution hereof. In the
event the Term of this Lease commences or ends on a day other than the first or
last day of a calendar month, then the Rent for such period shall be prorated
in the proportion that the number of days this Lease is in effect during such
periods bears to thirty (30), and such Rent shall be paid at the commencement
of such period. In addition to the Annual Basic Rent, Tenant agrees to pay the
amount of the Rental Adjustments as and when hereinafter provided in this Lease.
Said rental shall be paid to Landlord, without any prior demand therefor and
without any deduction or offset whatsoever in lawful money of the United States
of America, which shall be legal tender at the time of payment, at the address
of Landlord designated in Subparagraph 1.b. or to such other person or at such
other place as Landlord may from time to time designate in writing. Tenant
agrees to pay as Additional Rent to Landlord, upon demand, Tenant's percentage
of any parking charges, utility surcharges, or any other costs levied, assessed
or imposed by, or at the direction of, or resulting from statutes or
regulations, or interpretations hereof, promulgated by any federal, state,
regional, municipal or local governmental authority in connection with the use
or occupancy of the Building or the Premises or the parking facilities serving
the Building or the Premises. Further, all charges to be paid by Tenant
hereunder, including, without limitation, payments for real property taxes,
insurance and repairs, shall be considered Additional Rent for the purposes of
this Lease, and the word "Rent" in this Lease shall include such Additional
Rent unless the context specifically or clearly implies that only the Annual
Basic Rent is referenced.

        b. The Annual Basic Rent as set forth hereinabove shall be increased
for each year ("Subsequent Year") of the term of this Lease following the
first year if the Consumer Price Index for All Urban Consumers 

                                       5
<PAGE>   7
(Seattle-Everett, Washington; Base 1967 = 100) ("Index"), as published by the
United States Department of Labor, Bureau of Labor Statistics, for the
"Comparison Month" (described below) increases over the Index for the calendar
month ("Base Month") which is four (4) months prior to the month in which
Tenant's obligation to pay Annual Basic Rent commences. The Base Month Index
shall be compared with the Index for the same calendar month for each
Subsequent Year by a percentage which shall be calculated by dividing the Base
Month Index into that number which represents the difference, if any, when
subtracting the Base Month index from the Index for any Comparison Month. In no
event shall the Annual Basic Rent be less than that set forth in Paragraph 5(a)
above. By way of illustration only, if Tenant commences paying Annual Basic
Rent in August of 1981, then the Base Month Index would be that for April,
1981, (assume such Index at 130) and that Index shall be compared with the
Index for April, 1982, (assume such Index at 136). Because the Index for April,
1982, is four and six-tenths percent (4.6%) higher than the Index for April,
1981, based on the assumptions of 136 and 130, respectively, the Annual Basic
Rent commencing in August of 1982 would be four and six-tenths percent (4.6%)
higher than the Annual Basic Rent commencing August, 1981. Likewise the Index
for April, 1983, would be compared with the Index for April, 1981. Should said
Bureau discontinue the publication of the above Index or publish the same less
frequently, or alter the same in some other manner, the Landlord shall adopt a
substitute Index or substitute procedure which reasonably reflects and monitors
consumer prices. This subparagraph shall be applicable only to rent for parking
and not for office space.

        c. LATE CHARGES. In the event Tenant fails to pay any installment of
Rent when due or in the event Tenant fails to make any other payment to be made
under this Lease when due, then Tenant shall pay to Landlord a late charge
equal to five percent (5%) of the amount due to compensate Landlord for the
extra cost incurred as a result of such late payment.

6.      RENTAL ADJUSTMENT.

        a. For the purpose of this Subparagraph 6.a. the following Terms 
are defined:

           (i) LEASE YEAR: Each calendar year of the Term of this Lease.

           (ii) TENANT'S PERCENTAGE: That portion of the building occupied by
Tenant divided by the total square footage of the Building available for
occupancy, which result is set forth as a percentage in Subparagraph l.m.

           (iii) DIRECT EXPENSE BASE: The amount of the annual Direct Expenses
which Landlord has included in the Annual Basic Rent and which amount is set
forth in Subparagraph 1.1.

           (iv) DIRECT EXPENSES: The Term "Direct Expenses" shall include:
 
        (a) Property tax costs consisting of real and personal property taxes
and assessments upon the Building and the land upon which it is located or
assessments levied in lieu thereof imposed by any governmental authority or
agency, and non-progressive tax on or measured by gross rental received from
the rental of space in the Building; any parking charges, utilities surcharges,
or any other costs levied, assessed or imposed by, or at the direction of, or
resulting from statutes or regulations, interpretations thereof, promulgated by
any federal, state, regional, municipal or local government authority in
connection with the use or occupancy of the Premises or the parking facilities
serving the Premises; any tax on this transaction or any document to which
Tenant is a party creating or transferring an interest in the Premises, and any
reasonable expenses, including reasonable cost of attorneys or expert
reasonably incurred by Landlord in seeking reduction by the taxing authority of
the above-referenced taxes, less tax refunds obtained as a result of an
application for review thereof; but shall not include any net income,
franchise, capital stock, estate or inheritance taxes.

        (b) Operating costs consisting of costs incurred by Landlord in
maintaining and operating the Building and the land upon which it is located,
exclusive of costs required to be capitalized for federal income tax purposes,
and including (without limiting the generality of the foregoing) the following:
cost of utilities, supplies and insurance, cost of services of independent
contractors, managers and other suppliers, the fair rental value of the
Building office, cost of compensation (including employment taxes and fringe
benefits) of all persons who perform regular and recurring duties connected
with the management, operation maintenance, and repair of the Building, its
equipment, parking facilities and the Common Areas, including, without
limitation, engineers, janitors, foremen, floor waxers, window washers,
watchmen and gardeners, but excluding persons performing services not uniformly
available to or performed for substantially all Building tenants.

        (c) Amortization of such capital improvements as Landlord may have
constructed: (1) for the purpose of reducing operating costs and (2) to comply
with governmental rules and regulations promulgated after completion of 
the Building.

        b. If Tenant's Percentage of the Direct Expenses paid or incurred by
Landlord for any Lease Year exceeds Tenant's percentage of the Direct Expense
Base, then Tenant shall pay such increase as additional rent. As soon as
possible each year Landlord shall give to Tenant an unaudited written statement
of the increase in rent payable by Tenant hereunder which shall be due and
payable upon receipt. In addition, for each year after the First Lease Year,
Tenant shall pay its percentage of Landlord's estimate of the amount by which
Direct Expenses for that year shall exceed, if any, the Direct Expense Base.
This amount shall be divided into twelve (12) equal monthly installments.
Tenant shall pay to Landlord concurrently with the regular monthly rent
payments next due following the receipt of such statement, an amount equal to
one (1) monthly installment multiplied by the number of months from January in
the calendar year in which said statement is submitted to the month of such
payment, both months inclusive. Subsequent installments shall be payable
concurrently with the regular monthly rent  
 
                                       6
<PAGE>   8
payments for the balance of that calendar year and shall continue until the
next calendar year's statement is rendered. If in any calendar year Tenant's
Percentage of actual Direct Expenses is less than the estimate for that year,
then upon receipt of Landlord's statement, any overpayment made by Tenant on
the monthly installment basis provided above shall be credited towards the
next monthly rent falling due and the estimated monthly installments of
Tenant's Percentage of Direct Expenses to be paid shall be adjusted to reflect
such lower Direct Expenses for the most recent Lease Year.

     c. Even though the Term has expired and Tenant has vacated the Premises,
when the final determination is made of Tenant Percentage of Direct Expenses
for the year in which this Lease Terminates, Tenant shall immediately pay any
increase due over the estimated expenses paid and conversely any overpayment
made in the event said expenses decrease shall be immediately rebated by
Landlord to Tenant.

     d. Landlord shall deliver to Tenant a statement, in no event later than
one hundred twenty (120) days following the end of each calendar year showing
the actual expenses incurred for the previous year. Once a year, Tenant shall
have the right upon reasonable and, mutually agreeable prior written notice to
Landlord, to review without limiting the foregoing, all invoices, charges, or
other records related to expenses charged to Tenant for such costs. Landlord
shall allow Tenant or its appointed representatives to review at Landlord's
principal office or Landlord's representative's office, during regular business
hours, any and all of the above-referenced records relating to the common
area costs.

7. SECURITY DEPOSIT. Tenant has deposited with Landlord the Security Deposit
designated in Subparagraph 1.n. subject to the right of partial refund as set
with therein. Said sum shall be held by Landlord as security for the faithful
performance by Tenant of all the terms, covenants, and conditions of this Lease
to be kept and performed by Tenant during the Term hereof. If Tenant defaults
with respect to any provision of this Lease, including but not limited by the
provisions relating to the payment of Rent, Landlord may (but shall not be
required to) use, apply or retain all or any part of this Security Deposit for
the payment of any Rent or any other sum in default, or for the payment of any
other such amount which Landlord may spend or become obligated to spend by
reason of Tenant's default or to compensate Landlord for any loss or damage
which Landlord may suffer by reason of Tenant's default. If any portion of said
deposit is so used or applied, Tenant shall, within ten (10) days after demand
therefor, deposit cash with Landlord in an amount sufficient to restore the
Security Deposit to its original amount. Tenant's failure to do so shall be a
material breach of this Lease. Landlord shall not be required to keep the
Security Deposit separate from its general funds, and Tenant shall not be
entitled to interest on such Security Deposit. Should Landlord sell its
interests in the Premises during the Term hereof and if Landlord deposits
with the purchaser thereof the then unappropriated funds deposited by
Tenant as aforesaid, thereupon Landlord shall be discharged from any further
liability with respect to the Security Deposit.

8. USE. Tenant shall use the Premises for general business office purposes and
uses incidental thereto, and shall not use the Premises, or permit or suffer
the Premises to be used for any other purpose without the written consent of
Landlord. Tenant shall not use or occupy the Premises in violation of law or
of the certificate of occupancy issued for the Building, or any master lease
underlying the Premises which Tenant has been notified, and shall, upon
five (5) days written notice from Landlord, discontinue any use of the
Premises which is declared by any governmental authority having jurisdiction
to be in violation of law or of said certificate of occupancy or ground lease.
Tenant shall comply with any direction of any governmental authority having
jurisdiction which shall, by reason of the nature of Tenant's use or occupancy
of the Premises, impose any duty upon Tenant or Landlord with respect to the
Premises or with respect to the use or occupation thereof. Tenant shall not do
or permit to be done anything which will invalidate, restrict or increase the
cost of any fire, "All-Risk", extended coverage or other insurance policy
covering the Building and/or property located therein, and shall comply with
all rules, orders, regulations and requirements of the Insurance Service
Offices, formerly known as the Pacific Fire Rating Bureau, or any other
organization performing a similar function. Tenant shall, promptly, upon
demand, reimburse Landlord for any additional premium charged to Landlord
for such policy by reason of Tenant's failure to comply with the provisions
of this Paragraph 8, and upon such payment, shall not be in breach of the
preceding sentence. Tenant shall not do or permit anything to be done in or
about the Premises which will in any way obstruct or interfere with the rights
of other tenants or occupants of the Building, or injure or annoy them, or use
or allow the Premises to be used for any improper, immoral, unlawful or
objectional purpose, nor shall Tenant cause, maintain or permit any nuisance
in, on or about the Premises. Tenant shall not commit or suffer to be committed
any waste in, on or about the Premises.

9. PAYMENT AND NOTICES. All Rent and other sums payable by Tenant to Landlord
hereunder shall be paid to Landlord at the address designated by Landlord in
Subparagraph 1.b. or at such other places as Landlord may hereafter designate
in writing. Any notice required or permitted to be given hereunder must be in
writing and may be given by personal delivery or by mail, and if given by mail
shall be deemed sufficiently given if sent by registered or certified mail,
return receipt requested, postage prepaid, addressed to Tenant at the Building
of which the Premises are a part; or to Landlord at its address designated in
Subparagraph 1.b. Either party may, by written notice to the other, specify a
different address for notice purposes except that Landlord may in any event use
the Premises as Tenant's address for notice purposes. If more than one tenant
is named under this Lease, service of any notice upon any one of said tenants
shall be deemed as service upon all said tenants.

10. BROKERS. The parties recognize that the brokers who negotiated this Lease
are the brokers whose names are stated in Subparagraph 1.p., and agree that
Landlord shall be solely responsible for the payment of brokerage commissions
to said brokers, and that Tenant shall have no responsibility therefor. If
Tenant has dealt with any other person or real estate broker with respect to
leasing or renting space in the Building, Tenant shall be solely responsible
for the payment of any fee due said person or firm and Tenant shall hold
Landlord free and harmless against any liability in respect thereto, including
attorney's fees and costs.

                                       7


<PAGE>   9
11. HOLDING OVER. If Tenant holds over after the expiration or earlier
Termination or the Term hereof without the express written consent of Landlord,
Tenant shall become a Tenant at sufferance only, at a rental rate equal to one
hundred twenty-five percent (125%) of the Rent in effect upon the date of such
expiration, and otherwise subject to the terms, covenants and conditions
herein specified so far as applicable. Acceptance by Landlord of Rent after
such expiration or earlier termination shall not constitute a holdover hereunder
or result in a renewal. The foregoing provisions of this Paragraph 11 are in
addition to and do not affect Landlord's right of re-entry or any rights of
Landlord hereunder or as otherwise provided by law. If Tenant fails to
surrender the Premises upon the expiration of this Lease despite demand to do
so by Landlord, Tenant shall indemnify and hold Landlord harmless from all loss
or liability, including without limitation, any claim made by any succeeding
tenant founded on or resulting from such failure to surrender and any
reasonable attorney's fees and costs.

12. TAXES ON TENANT'S PROPERTY.

         a. Tenant shall be liable for and shall pay at least ten (10) days
before delinquency, taxes levied against any personal property or trade
fixtures placed by Tenant in or about the Premises. If any such taxes on
Tenant's personal property or trade fixtures are levied against Landlord or
Landlord's property or if the assessed value of the Premises is increased by
the inclusion therein of a value placed upon such personal property or trade
fixtures of Tenant, then Landlord, after written notice to Tenant, shall have
the right to pay the taxes based upon such increased assessments, regardless of
the validity thereof, but only under proper protest if requested by Tenant in
writing. If Landlord shall do so, then Tenant shall, upon demand, repay to
Landlord the taxes levied against Landlord, or the proportion of such taxes
resulting from such increase in the assessment.

13. CONDITION OF PREMISES. Tenant acknowledges that neither Landlord nor any
agent of Landlord has made any representation or warranty with respect to the
Premises or the Building or with respect to the suitability of either for the
conduct of Tenant's business. The taking of possession of the Premises by Tenant
shall conclusively establish that the Premises and the Building were at such
time in satisfactory condition.

14. ALTERATIONS.

         a. Tenant shall make no alterations, decorations, additions or
improvements in or to the Premises without Landlord's prior written consent, and
then only by contractors or mechanics first approved by Landlord in writing.
Tenant agrees that there shall be no construction of partitions or other
obstructions which might interfere with Landlord's free access to mechanical
installations or service facilities of the Building or interfere with the moving
of Landlord's equipment to or from the enclosures containing said installations
or facilities. All such work shall be done at such times and in such manner as
Landlord may from time to time designate. Tenant covenants and agrees that all
work done by Tenant shall be performed in full compliance with all laws, rules,
orders, ordinances, directions, regulations and requirements of all governmental
agencies, offices, departments, bureaus and boards having jurisdiction. Before
commencing any work, Tenant shall give Landlord at least five (5) days written
notice of the proposed commencement of such work, and shall, if required by
Landlord, secure at Tenant's own cost and expense, a completion and lien
indemnity bond, reasonably satisfactory to Landlord, for said work. Tenant
further covenants and agrees that any mechanic's liens filed against the
Premises or against the Building for work claimed to have been done, or
materials claimed to have been furnished to Tenant, will be discharged by
Tenant, by bond or otherwise, within ten (10) days after the filing thereof, at
the cost and expense of Tenant. All additional alterations, decorations,
additions or improvements upon the Premises, made by either party, including
(without limiting the generality of the foregoing) all wall covering, built-in
cabinet work, paneling and the like, shall, unless Landlord elects otherwise,
become the property  of Landlord, and shall remain upon, and be surrendered with
the Premises, as a part thereof, at the end of the Term hereof. However,
Landlord may, by written notice to Tenant,  given at least thirty (30) days
prior to the end of the Term, require Tenant to remove all partitions, counters,
railings, and the like, installed by Tenant, and Tenant shall repair any damage
to the Premises arising from such removal or, at Landlord's option, shall pay to
Landlord all of Landlord's reasonable costs of such removal and repair. Such
removal by Tenant of any such improvements shall not interfere, in any way, with
any other tenant's quiet enjoyment of the Building. 

     b. All articles of personal property and all business and trade fixtures,
machinery and equipment, furniture and movable partitions owned by Tenant or
installed by Tenant at its expense in the Premises shall be and remain the
property of Tenant and may be removed by Tenant at any time during the Term,
provided Tenant is not in default hereunder, and provided further that Tenant
shall repair any damage caused by such removal. If Tenant shall fail to remove
all of its effects from the Premises upon termination of this Lease for any
cause whatsoever, Landlord may, at its option, remove the same in any
reasonable manner that Landlord shall choose, and store said effects without
liability to Tenant for loss thereof. Tenant agrees to pay Landlord upon
demand any and all reasonable expenses incurred in such removal, including court
costs and attorney's fees and storage charges on such effects for any length of
time that the same shall be in Landlord's possession. Landlord may, at its
option and without notice, sell said effects, or any of the same, at private
sale and without legal process, for such price as Landlord may obtain and
apply the proceeds of such sale upon (i) any amounts due under this Lease from
Tenant to Landlord and (ii) the expenses incident to the removal and sale of
said effects.

     c. Landlord reserves the right at any time and from time to time without
the same constituting an actual or constructive eviction and without insuring
any liability to Tenant therefor or otherwise affecting Tenant's obligations
under this Lease, to make such changes, alterations, additions, improvements,
repairs or replacements in or to the Building (including the Premises, if
required so to do by any law or regulation) and the fixtures and equipment
thereof, as well as in or to the street entrances, halls, passages and
stairways thereof, and to change the name by which the Building is commonly
known, as Landlord may deem necessary or desirable. Nothing

                                       8
<PAGE>   10
contained in this Subparagraph 14.c. shall be deemed to relieve Tenant of any
duty, obligation or liability of Tenant with respect to making any repair,
replacement or improvement or complying with any law, order or requirement of
any government or other authority. Nothing contained in this Subparagraph 14.c.
shall be deemed or construed to impose upon Landlord any obligation,
responsibility or liability whatsoever, for the care, supervision or repair of
the Building or any part other than as expressly provided in this Lease.

15. REPAIRS.

        a. By entry hereunder, Tenant accepts and Landlord delivers the
Premises as being in good and sanitary order, condition and repair. Tenant
shall keep, maintain and preserve the Premises in first class condition and
repair, and shall, when and if needed or whenever requested by Landlord to do
so, at Tenant's sole cost and expense, make all repairs to the Premises and
every part thereof, including all interior windows and doors. Tenant shall,
upon the expiration or sooner termination of the Term hereof, surrender the
Premises to Landlord in the same condition as when received, except for normal
wear and tear or any alterations that have been approved by Landlord except as
designated in advance in writing at the time of Landlord's approval. Landlord
shall have no obligation to alter, remodel, improve, repair, decorate or paint
the Premises or any part thereof except as specifically provided in Exhibits
"B" and "B-1". The parties hereto affirm that Landlord has made no
representations to Tenant respecting the condition of the Premises or the
Building except as specifically set forth.

        b. Anything contained in Subparagraph 15.a. above to the contrary
notwithstanding, Landlord shall repair and maintain the structural portions of
the Building, including the basic plumbing, heating, ventilating, air
conditioning and electrical systems installed or furnished by Landlord, unless
such maintenance and repairs are caused in part or in whole by the act,
neglect, fault of or omission of any duty by Tenant, its agents, servants,
employees or invitees, in which case Tenant shall pay to Landlord, as
additional rent, the reasonable cost of such maintenance and repairs. Landlord
shall not be liable for any failure to make any such repairs or to perform any
maintenance unless such failure shall persist for an unreasonable time after
written notice of the need of such repair or maintenance is given to Landlord
by Tenant. Except as provided in Paragraph 23 hereof, there shall be no
abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business arising from the making of any repairs,
alterations or improvements in or to any portion of the Building or the
Premises or to fixtures, appurtenances and equipment therein.

16. LIENS. Tenant shall not cause any mechanic's, materialmen's or other liens
to be filed against the real property of which the Premises form a part nor
against Tenant's leasehold interest in the Premises. If any such liens are
filed, Landlord may, without waiving its rights and remedies based on such
breach of Tenant, and without releasing Tenant from any of its obligations,
cause such liens to be released by any means it shall deem proper, including
payments in satisfaction of the claim giving rise to such lien. Tenant shall
pay to Landlord at once, upon notice by Landlord, any sum paid by Landlord to
remove such liens, together with interest at the maximum rate per annum
permitted by law from the date of such payment by Landlord.

17. ENTRY BY LANDLORD. Landlord reserves and shall at any and all reasonable
times have the right to enter the Premises to inspect the same, to supply
janitor service and any other service to be provided by Landlord to Tenant
hereunder, to submit said Premises to prospective purchasers or tenants, to
alter, improve or repair the Premises or any other portion of the Building, all
without being deemed guilty of any eviction of Tenant and without abatement of
Rent, and may, in order to carry out such purposes, erect scaffolding and other
necessary structures where reasonably required by the character of the work to
be performed, provided that the business of Tenant shall be interfered with as
little as is reasonably practicable. Tenant hereby waives any claim for damages
for any injury or inconvenience to or interference with Tenant's business, any
loss of occupancy or quiet enjoyment of the Premises, and any other loss in,
upon and about the Premises, and any other loss occasioned thereby. For each of
the aforesaid purposes, Landlord shall at all times, have and retain a key with
which to unlock all of the doors in, upon and about the Premises, excluding
Tenant's vaults and safes. Landlord shall have the right to use any and all
means which Landlord may deem proper to open said doors in an emergency in
order to obtain entry to the Premises, and any entry to the Premises obtained
by Landlord by any of said means, or otherwise, shall not under any
circumstances be construed or deemed to be a forcible or unlawful entry into,
or a detainer of, the Premises, or an eviction of Tenant from the Premises or
any portion thereof, and any damages caused on account thereof shall be paid by
Tenant. It is understood and agreed that no provision of this Lease shall be
construed as obligating Landlord to perform any repairs, alterations or
decorations except as otherwise expressly agreed herein to be performed by
Landlord.

18. UTILITIES AND SERVICES. Provided that Tenant is not in default of this
Lease, Landlord agrees to furnish or cause to be furnished to the Premises the
utilities and services described in the Standards for Utilities and Services,
attached hereto as Exhibit "D", subject to the conditions and in accordance
with the standards set forth therein. Landlord shall not be liable for, Tenant
shall not be entitled to any abatement or reduction of rent by reason of, and
no eviction of Tenant shall result from, and Tenant shall not be relieved from
the performance of any covenant or agreement in this Lease because of,
Landlord's failure to furnish any of the foregoing when such failure is caused
by accident, breakage, repairs, strikes, lockouts or other labor disturbances
or labor dispute of any character, governmental regulation, moratorium or other
cause beyond Landlord's reasonable control. In the event of any failure,
stoppage or interruption thereof, Landlord shall diligently attempt to promptly
resume service.

19. BANKRUPTCY. If Tenant shall file a petition of bankruptcy under any Chapter
of the Bankruptcy Act as then in effect, or if Tenant shall be adjudicated a
bankrupt in involuntary bankruptcy proceedings and such adjudication shall not
have been vacated within thirty (30) days from the date thereof, or if a
receiver or trustee shall be appointed of Tenant's property, and the order
appointing such receiver or trustee shall not be set aside or vacated 

                                       9
<PAGE>   11
within thirty (30) days after the entry thereof, or if Tenant shall assign
Tenant's estate or effects for the benefit of creditors,
or if this Lease shall by operation of law or otherwise devolve or pass to any
person or persons other than Tenant, then in any such event Landlord may, if
Landlord so elects, with or without notice of such election and with or without
entry or action by Landlord, forthwith terminate this Lease. In such case,
notwithstanding any other provisions of this Lease, Landlord, in addition to
any and all rights and remedies allowed by law or equity, shall, upon such
termination, be entitled to recover damages in the amount provided in
Subparagraph 25.b. Neither Tenant nor any person claiming through or under
Tenant or by virtue of any statute or order of any court shall be entitled to
possession of the Premises, but shall forthwith quit and surrender the Premises
to Landlord. Nothing herein contained shall limit or prejudice the right of
Landlord to prove and obtain as damages by reason of any such termination an
amount equal to the maximum allowed by any statute or rule of law in effect at
the time when, and governing the proceedings in which, such damages are to be
proved, whether or not such amount be greater, equal to, or less than the
amount of damages recoverable under the provisions of this Paragraph 19.

20. INDEMNIFICATION. Tenant shall indemnify, and hold harmless Landlord against
and from any and all claims arising from Tenant's use of the Premises or the
conduct of its business or from any activity, work, or thing done, permitted or
suffered by Tenant in or about the Premises. Tenant shall further indemnify, and
hold harmless Landlord against and from any and all claims arising from any
breach or default in the performance or any obligation on Tenant's part to be
performed under the Terms of this Lease, or arising from any act, neglect, fault
or omission of Tenant or of its agents or employees, and from and against all
costs, attorney's fees, expenses and liabilities incurred in or about such claim
or any action or proceeding brought thereon. In case any action or proceeding
shall be brought against Landlord by reason of any such claim, Tenant, upon
notice from Landlord, shall defend the same at Tenants expense by counsel
approved in writing by Landlord. Tenant, as a material part of the consideration
to Landlord, hereby assumes all risk of damage to property or injury to person
in, upon or about the Premises from any cause whatsoever, except that which is
caused by Landlord's negligence or the failure of Landlord to observe any of the
terms and conditions of this Lease where such failure has persisted for an
unreasonable period of time after written notice of such failure.

21. DAMAGE TO TENANT'S PROPERTY. Notwithstanding the provisions of Paragraph 20
to the contrary, Landlord or its agents shall not be liable for any damage to
property entrusted to employees of the Building, not for loss or damage to any
property by theft or otherwise, not for any injury or damage to persons or
property resulting from fire, explosion, falling plaster, steam, gas,
electricity, water or rain which may leak from any part of the Building or from
the pipes, appliances or plumbing work therein or from the roof, street or
sub-surface or from any other place or resulting from dampness or any other
cause whatsoever except to the extent that such damage or loss is attributable
to the breech of any of Landlord's obligations hereunder or Landlord's
negligence. Landlord or its agents shall not be liable for interference with
light or other incorporeal hereditaments, nor shall Landlord be liable for any
latent defect in the Premises or in the Building. Tenant shall give prompt
notice to Landlord in case of fire or accidents in the Premises or in the
Building or of defects therein or in the fixtures or equipment.

22. TENANT'S INSURANCE.

        a. Tenant shall, during the Term hereof and any other period of
occupancy, at its sole cost and expense, obtain, maintain and keep in full
force and effect the following insurance:

                (i) Standard Form Property Insurance insuring against the
perils of fire, extended coverage, vandalism, malicious mischief, special
extended coverage ("All-Risk") and sprinkler leakage. This insurance policy
shall be upon property of every description and kind owned by Tenant, for which
Tenant is legally liable or that was installed at Tenant's expense, and which
is located in the Building, including without limitation, furniture, fittings,
installations, fixture (other than Building Standard Work), and any other
personal property, in an amount not less than ninety percent (90%) of the full
replacement cost thereof. This insurance policy shall also be upon direct or
indirect loss of Tenant's earnings attributable to Tenant's inability to use
fully or obtain access to the Premises or Building in an amount as will
properly reimburse Tenant. Such policy shall name Landlord and any mortgages of
Landlord as Additional Insured as their respective interests may appear.

                (ii) Comprehensive General Liability Insurance insuring Tenant
against any liability arising out of the lease, use, occupancy or maintenance of
the Premises and all areas appurtenant thereto. Such insurance shall be in the
amount of $1,000,000 Combined Single Limit for injury to, or death of one or
more persons in an occurrence, and for damage to tangible property (including
loss of use) in an occurrence. The policy shall insure the hazards of premises
and operations, independent contractors, contractual liability (covering the
indemnity contained in Paragraph 20 hereof) and shall (a) name Landlord as an
Additional Insured, (b) contain a Cross Liability provision, and (c) contain a
provision that "the insurance provided the Landlord hereunder shall be primary
and non-contributing with any other insurance available to the Landlord".

                (iii) Workmen's Compensation and Employer's Liability Insurance
(as required by state law).

                (iv) Any other form or forms of insurance as Tenant or Landlord
or any mortgages of Landlord may reasonably require from time to time in form,
in amounts and for insurance risks against which a prudent tenant would protect
itself.

        b. All policies shall be written in a form satisfactory to Landlord and
shall be taken out with insurance companies holding a General Policyholders
Rating of "A" and a Financial Rating of "X" or better, as set forth in the most
current issue of Bests Insurance Guide. Tenant shall deliver to Landlord
Certificates of Insurance satisfactory to Landlord. No such policy shall be
cancelable or reducible in coverage except after thirty (30) days prior written
notice to Landlord. Tenant shall, within ten (10) days prior to the expiration
of such policies, furnish

                                       10

<PAGE>   12
Landlord with renewals or "binders" thereof, or Landlord may order such
insurance and charge the cost thereof to Tenant as Additional Rent. If Landlord
obtains any insurance that is the responsibility of Tenant under this Paragraph
22, Landlord shall deliver to Tenant a written statement setting forth the
amount of any such insurance cost increase and showing in reasonable detail the
manner in which it has been computed.

23. DAMAGE OR DESTRUCTION.

     a. In the event the Building and/or Building Standard Work are damaged by
fire or other perils covered by Landlord's extended coverage insurance Landlord
shall:

        (i) In the event of total destruction, at Landlord's option, within a
period of ninety (90) days thereafter, commence repair, reconstruction and
restoration of the Building and/or Building Standard Work and prosecute the
same diligently to completion, in which event this Lease shall remain in full
force and effect; or within said ninety (90) day period elect not to so repair,
reconstruct or restore the Building and/or Building Standard Work in which event
this Lease shall terminate. In the event Landlord elects not to restore the
Building and/or Building Standard Improvements, this Lease shall be deemed to
have terminated as of the date of such total destruction.

        (ii) In the event of a partial destruction of the Building and/or
Building Standard Improvements, to an extent not exceeding twenty-five percent
(25%) of the full insurable value thereof and if the damage thereto is such
that the building and/or the Building Standard Improvements may be repaired,
reconstructed or restored within a period of ninety (90) days from the date of
the happening of such casualty and Landlord will receive insurance proceeds
sufficient to cover the cost of such repairs, Landlord shall commence and
proceed diligently with the work of repair, reconstruction and restoration and
this Lease shall continue in full force and effect. If such work or repair
reconstruction and restoration is such as to require a period longer than
ninety (90) days or exceeds twenty-five percent (25%) of the full insurable
value thereof, or if said insurance proceeds will not be sufficient to cover
the cost of such repairs, Landlord either may elect to so repair, reconstruct
or restore and this Lease shall continue in full force and effect or Landlord
may elect not to repair, reconstruct or restore and this Lease shall in such
event terminate. Under any of the conditions of this Subparagraph 23. a.
(ii), Landlord shall give written notice to Tenant of its intention within
said ninety (90) day period. In the event Landlord elects not to restore said
Building and/or Building Standard Improvements, this Lease shall be deemed to
have terminated as of the date of such partial destruction.

     b. Upon any termination of this Lease under any of the provisions of this
Paragraph 23, the parties shall be released thereby without further obligation
to the other from the date possession of the Premises is surrendered to
Landlord except for items which have therefor accrued and are then unpaid.

     c. In the event of repair, reconstruction and restoration by Landlord
as herein provided, the Rent provided to be paid under this Lease shall be
abated proportionately with the degree to which Tenant's use of the premises is
impaired during the period of such repair, reconstruction or restoration. Tenant
shall not be entitled to any compensation or damages for loss in the use of the
whole or any part of the Premises and/or any inconvenience or annoyance
occasioned by such damage, repair, reconstruction or restoration.

     d. Tenant shall not be released from any of its obligations under this
Lease, except to the extent and upon the conditions expressly stated in this
Paragraph 23. Notwithstanding anything to the contrary contained in this
Paragraph 23, should Landlord be delayed or prevented from repairing or
restoring the damaged Premises within one (1) year after the occurrence of
such damage or destruction by reason of acts of God, war, governmental
restrictions, inability to procure the necessary labor or materials, or other
cause beyond the control of Landlord, Landlord shall be relieved of its
obligation to make such repairs or restoration and Tenant shall be released
from its obligations under this Lease as of the end of said one (1) year period.

     e. In the event that damage is due to any cause other than fire or other
peril covered by extended coverage insurance, Landlord may elect to terminate
this Lease.

     f. It is hereby understood that if Landlord is obligated to or elects to
repair or restore as herein provided, Landlord shall be obligated to make repair
or restoration only to those portions of the Building and the Premises which
were originally provided at Landlord's expense, and the repair and restoration
of items not provided at Landlord's expense shall be the obligation of Tenant.

     g. Notwithstanding anything to the contrary contained in Paragraph 21,
Landlord shall not have any obligation whatsoever to repair, reconstruct or
restore the Premises when the damage resulting from any casualty covered under
this Paragraph 23 occurs during the last twelve (12) months of the Term of this
Lease or any extension hereof. In the event Landlord exercises its rights
hereunder, the lease shall terminate effective as of the date of the casualty.

24. EMINENT DOMAIN. In the case the whole of the Premises, or such part thereof
as shall substantially interfere with Tenant's use and occupancy thereof, shall
be taken for any public or quasi-public purpose by any lawful power or authority
by exercise of the right of appropriation, condemnation or eminent domain, or
sold to prevent such taking, either party shall have the right to terminate this
Lease effective as of the date possession is required to be surrendered to said
authority. Tenant shall not assert any claim against Landlord or the taking
authority for any compensation because of such taking, and Landlord shall be
entitled to receive the entire amount of the award without deduction for any
estate or interest or Tenant, and Landlord, at its option, may terminate this
Lease. If Landlord does not so elect, Landlord shall promptly proceed to restore
the premises to substantially the same condition prior to such partial taking,
and a proportionate allowance shall be made to Tenant of the Rent

                                       11
<PAGE>   13
corresponding to the time during which, and to the part of the Premises of
which, Tenant shall be so deprived on account of such taking and restoration.
Nothing contained in this Paragraph 24 shall be deemed to give Landlord any
interest in any award made to Tenant for the taking of personal property and
fixtures belonging to Tenant.

25. DEFAULTS AND REMEDIES.

        a. The occurrence or any one or more of the following events shall
constitute a default hereunder by Tenant:

                (i) The vacation or abandonment of the premises by Tenant.
Abandonment is herein defined to include, but is not limited to, any absence
from the Premises for five (5) business days or longer while in default of any
provision of this Lease.

                (ii) The failure by Tenant to make any payment of Rent or
Additional Rent or any other payment required to be made by Tenant hereunder,
as and when due, where such failure shall continue for a period of three (3)
days after written notice thereof from Landlord to Tenant.

                (iii) The failure by Tenant to observe or perform any of the
express or implied covenants or provisions of this Lease to be observed or
performed by Tenant, other than as specified in Subparagraph 25.1.a(i) or (ii)
above where such failure shall continue for a period of ten (10) days after
written notice thereof from Landlord to Tenant; provided, however, that if the
nature of Tenant's default is such that more than ten (10) days are
reasonably required for its cure, then Tenant shall not be deemed to be in
default if Tenant shall commence such cure within said ten (10) day period and
thereafter diligently prosecute such cure to completion, which completion shall
occur not later than sixty (60) days from the date of such notice from Landlord.

                (iv) The making by Tenant of any general assignment for the
benefit of creditors.

                (v) The filing by or against Tenant of a petition to have
Tenant adjudged as bankrupt or a petition for reorganization or arrangement
under any law relating to bankruptcy (unless, in the case of a petition filed
against Tenant, the same is dismissed within sixty (60) days).

                (vi) The appointment of a trustee or receiver to take
possession of substantially all of Tenant's assets located at the Premises or
of Tenant's interest in this Lease where possession is not restored to Tenant
within thirty (30) days.

                (vii) The attachment, execution or other judicial seizure of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease where such seizure is not discharged within thirty (30)
days.

        b. In the event of any such default by Tenant, in addition to any other
remedies available to Landlord at law or in equity, Landlord shall have the
immediate option to terminate this Lease and all rights of Tenant hereunder. In
the event that Landlord shall elect to do so terminate this lease then Landlord
may recover from Tenant:

                (i) the worth at the time of award of any unpaid Rent which had
been earned at the time of such termination; plus

                (ii) the worth at the time of award of the amount by which the
unpaid Rent which would have been earned after termination until the time of
award exceeds the amount of such Rent loss that Tenant proves could have been
reasonably avoided; plus

                (iii) the worth at the time of award of the amount by which the
unpaid Rent for the balance of the Term after the time of award exceeds the
amount of such Rent loss that Tenant proves could be reasonably avoided; plus

                (iv) any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom.

        As used in Subparagraphs 25.b(i) and (ii), the "worth at the time of
award" is computed by allowing interest at the lesser of eighteen per cent
(18%) per annum, compounded monthly, or the maximum rate permitted by law per
annum. As used in subparagraph 25.b(iii), the "worth at the time of award" is
computed by discounting such amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of award plus one percent (1%).

        c. In the event of any such default by Tenant, Landlord shall also have
the right, with or without terminating this Lease, to re-enter the Premises and
remove all persons and property from the Premises; such property may be removed
and stored in a public warehouse or elsewhere at the cost of and for the
account of Tenant. No re-entry or taking possession of the Premises by Landlord
pursuant to this Subparagraph 25.c. shall be construed as an election to
terminate this Lease unless a written notice of such intention be given to
Tenant or unless the termination thereof be decreed by a court or competent
jurisdiction.

                                       12
<PAGE>   14
     d. All rights, options and remedies of Landlord contained in this Lease
shall be construed and held to be cumulative, and no one of them shall be
exclusive of the other, and Landlord shall have the right to pursue any one or
all of such remedies or any other remedy or relief which may be provided by
law, whether or not stated in this Lease. No waiver of any default of Tenant
hereunder shall be implied from any acceptance by Landlord of any Rent or other
payment due hereunder or any omission by Landlord to take any action on account
of such default if such default persists or is repeated, and no express waiver
shall affect defaults other than as specified in said waiver. The consent or
approval of Landlord to or of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
or approval to or of any subsequent similar acts by Tenant.

26. ASSIGNMENT AND SUBLETTING.

     a. Tenant shall not, either voluntarily or by operation of law, assign,
sell, hypothecate or transfer this Lease, or sublet the Premises or any part
thereof, or permit or suffer the Premises or any part thereof to be used or
occupied as work space, storage space, mail drop, concession or otherwise, by
anyone other than Tenant or Tenant's employees without the prior written
consent of Landlord in each instance. In the event Tenant desires to assign,
hypothecate or otherwise transfer this Lease or sublet the Premises, then at
least thirty (30) days prior to the date when Tenant desires the assignment to
sublease to be effective (the "Assignment Date"), Tenant shall give Landlord a
notice (the "Assignment Notice"), which shall set forth the name, address and
business of the proposed assignee or sublessee, information (including
references) concerning the character, ownership, and financial condition of the
proposed assignee or sublessee, the Assignment Date, any ownership or
commercial relationship between Tenant and the proposed assignee or sublessee,
and the consideration and all other material terms and conditions of the
proposed assignment or sublease, all in such detail as Landlord shall
reasonably require. If Landlord requests additional detail, the Assignment
Notice shall not be deemed to have been received until Landlord receives such
additional detail, and Landlord may withhold consent to any assignment or
sublease until such information is provided to it. Any sale, assignment,
hypothecation or transfer of this Lease or subletting of the Premises that is
not in compliance with the provisions of this Subparagraph 26.a. shall be void
and shall, at the option of Landlord, terminate this Lease. The consent by
Landlord to any assignment or subletting shall not be construed as relieving
Tenant or any assignee of this Lease or sublessee of the Premises from
obtaining the express written consent of Landlord to any further assignment of
subletting or as releasing Tenant or any assignee or sublessee of Tenant from
any liability or obligation hereunder whether or not then accrued. In the event
Landlord shall consent to an assignment or sublease, Tenant shall pay Landlord
as Additional Rent a reasonable attorneys' and administrative fee not to exceed
$500.00 for costs incurred in connection with evaluating the Assignment Notice.
This Subparagraph 26.a. shall be fully applicable to all further sales,
hypothecations, transfers, assignments and subleases of any portion of the
Premises by any successor or assignee of Tenant, or any sublessee of the
Premises.

     b. Landlord may, in its absolute discretion, withhold consent to any
assignment, sale, hypothecation or transfer of this Lease for any reason
whatsoever. As used in this Paragraph 26, the subletting of substantially all
of the Premises for substantially all of the remaining Term of this Lease
shall be deemed an assignment rather than a sublease. Notwithstanding the
foregoing, Landlord shall consent to the assignment, sale or transfer if the
assignment Notice states that Tenant desires to assign this Lease to any entity
into which Tenant is merged, with which Tenant is consolidated or which
acquires all of substantially all of the assets of Tenant, provided that the
assignee first executes, acknowledges and delivers to Landlord an agreement
whereby the assignee agrees to be bound by all of the covenants and agreements
in this Lease which Tenant has agreed to keep, observe or perform, that the
assignee agrees that the provisions of this Paragraph 26 shall be binding upon
it as if it were the original Tenant hereunder and that the assignee shall have
a net worth (determined in accordance with generally accepted accounting
principles consistently applied) immediately after such assignment which is at
least equal to the net worth (as so determined) of Tenant immediately prior to
the assignment.

     c. Except as provided above, Landlord's consent to any sublease shall not
be unreasonably withheld. If Tenant shall sublet all or any portion of the
Premises that Tenant has occupied for its own use at any time, then any
consideration paid by the sublessee for the portion of the Premises being
sublet that previously was occupied by Tenant that exceeds the Annual Basic
Rent and Rental Adjustments provided by this Lease for such portion of the
Premises being sublet shall be due, owing and payable by Tenant to Landlord
when paid or owing by the sublessee under the sublease. Should the
consideration paid by the sublessee exceed the rental amounts stated above,
Tenant shall be entitled to reimbursement for Leasing Commissions or
Landlord-approved Tenant Improvements Tenant paid to procure the sublease,
amortized in equal, non-interest bearing, monthly installments over the term of
the sublease. The parties intend that the preceding sentences shall not apply
to any sublease rentals respecting a portion of the Premises that during the
entire Term of this Lease was not occupied by Tenant for its own use, but was
always subleased by Tenant and/or kept vacant. For the purpose of this
Subparagraph 26.c., the rent for each square foot of floor space in the
Premises shall be deemed equal.

27. SUBORDINATION. Without the necessity of any additional document being
executed by Tenant for the purpose of effecting a subordination, and at the
election of Landlord or any first mortgagee with a lien on the Building or any
ground lessor with respect to the building, this Lease shall be subject and
subordinate at all times to:

     a. all ground leases or underlying leases which may now exist or hereafter
be executed affecting the Building or the land upon which the Building is
situated or both, and

     b. the lien of any mortgage or deed of trust which may now exist or
hereafter be executed in any amount for which the Building, land, ground leases
or underlying leases, or Landlord's interest or estate in any of said items is
specified as security.

                                       13
<PAGE>   15
        Notwithstanding the foregoing, Landlord shall have the right to
subordinate or cause to be subordinated any such ground leases or underlying
leases or any such liens to this Lease. In the event that any ground lease or
underlying lease terminates for any reason or any mortgage or deed of trust is
foreclosed or a conveyance in lieu of foreclosure is made for any reason,
Tenant shall, notwithstanding any subordination, attorn to and become the
Tenant of the successor in interest to Landlord, at the option of said
successor in interest. Tenant covenants and agrees to execute and deliver, upon
demand by Landlord and in the form requested by Landlord, any additional
documents evidencing the priority or subordination of this Lease with respect
to any such ground leases or underlying leases or the lien of any such mortgage
or deed of trust and hereby irrevocably appoints Landlord as attorney-in-fact
of Tenant to execute, deliver and record any such document in the name and on
behalf of Tenant.

28. ESTOPPEL CERTIFICATE.

        a. Within ten (10) days following any written request which Landlord
may make from time to time, Tenant shall execute and deliver to Landlord a
statement certifying: (i) the Commencement Date of this Lease; (ii) the fact
that this Lease is unmodified and in full force and effect (or, if there have
been modifications hereto, that this Lease is in full force and effect, and
stating the date and nature of such modifications); (iii) the date to which the
Rent and other sums payable under this Lease have been paid; (iv) that there
are no current defaults under this Lease by either Landlord or Tenant except as
specified in Tenant's statement; and (v) such other matters requested by
Landlord. Landlord and Tenant intend that any statement delivered pursuant to
this Paragraph 28 may be relied upon by any mortgages, beneficiary, purchaser,
or prospective purchaser of the Building, property or any interest therein.

        b. Tenant's failure to deliver such statement within such time shall be

34. ATTORNEY'S FEES.

        a. In the event that Landlord should bring suit for the possession of
the Premises, for the recovery of any sum due under this Lease, or because of
the breach of any provision of this Lease, or for any other relief against
Tenant hereunder, then all costs and expenses, including reasonable attorney's

opportunity to cure the default, including the time to obtain possession of the
Premises by power of sale or a judicial foreclosure, if such should prove
necessary to effect a cure.

37. DEFINITION OF LANDLORD. The term "Landlord" as used in this Lease, so far
as covenants or obligations on the part of Landlord are concerned, shall be
limited to mean and include only the owner or owners, at the time in question,
of the fee title of the Premises or the Lessees under any ground lease, if any.
In the event of any transfer, assignment or other conveyance or transfers of
any such title, Landlord herein named (and in the case of any subsequent
transfers or conveyances, the then grantor) shall be automatically freed and
relieved from and after the date of such transfer, assignment or conveyance of
all liability as respects  the performance of any covenants or obligations on
the part of Landlord contained in this lease thereafter to be performed.
Without further agreement, the transferee of such title shall be deemed to have
assumed and agreed to observe and perform any and all obligations of Landlord
thereunder, during its ownership to the Premises. Landlord may transfer its
interest in the Premises without the consent of Tenant and such transfer or
subsequent transfer shall not be deemed a violation on Landlord's part of any
of the terms and conditions of this Lease.

38. WAIVER. The waiver by Landlord of any breach of any term, covenant or
condition herein contained shall not be deemed to be a waiver of any subsequent
breach of the same or any other term, covenant or condition herein contained,
nor shall any custom or practice which may grow up between the parties in the
administration of the terms hereof be deemed a waiver of or in any way affect
the rights of Landlord to insist upon the performance by Tenant in strict
accordance with said terms. The subsequent acceptance of Rent hereunder by
Landlord shall not be deemed to be a waiver of any preceding breach by Tenant
of any term, covenant or condition of this Lease, other than the failure of
Tenant to pay the particular Rent so accepted, regardless of Landlord's
knowledge of such preceding breach at the time of acceptance of such Rent.

39. IDENTIFICATION OF TENANT. If more than one person executes this Lease as
Tenant:

        a. each of them is jointly and severally liable for the keeping,

and agreements of this Lease to be kept, observed and performed by Tenant; and

        b. the term "Tenant" as used in this Lease shall mean and include each
of them jointly and severally.

any one or more of them, with respect to the tenancy of this Lease, including,
but not limited to, any renewal, extensions, expiration, termination or
modification of this Lease, shall be binding upon each and all of the persons
executing this Lease as Tenant with the same force and effect as if each and
all of them has so acted or so given or received such notice or refund or so
signed.

40. PARKING. As an appurtenance to the Premises, Tenant is entitled to use the
number of parking spaces in the parking facilities of the Building designated
in Subparagraph 1.o. Tenant may use such parking spaces upon the terms and
conditions provided in the Parking Rules attached hereto as Exhibit "E", if
any, and all reasonable and nondiscriminatory modifications thereto from time
to time put into effect by Landlord. Landlord may contract with a Parking
Operator to operate the parking facilities. Landlord and the Parking Operator
shall not be responsible for the violation or nonperformance by any other
tenant or any agent, employee or invitee thereof of any of said terms and
conditions. Tenant shall pay to Landlord, as and when billed and as Additional
Rent, the amount per space designated in Paragraph 1.o., if any, times the
number of spaces shown there, or such other nondiscriminatory charges for
monthly parking set forth from time to time by Landlord.

other genders. The paragraph headings of this Lease are not a part of this
Lease and shall have no effect upon the construction or interpretation of any
part hereof.

signature by Tenant does not constitute a reservation of or option for lease,
and is not effective as a lease or otherwise until execution by and delivery to
both Landlord and Tenant.

43. TIME. Time is of the essence with respect to the performance of every
provision of this Lease in which time or performance is a factor.

44. PRIOR AGREEMENT; AMENDMENTS. This Lease contains all of the agreements of
the parties hereto with respect to any matter covered or mentioned in this
Lease, and no prior agreement or understanding pertaining to any such matter
shall be effective for any purpose. No provisions of this Lease may be amended
or added to except by an agreement in writing signed by the parties hereto or
their respective successors in interest.

45. SEPARABILITY. Any provision of this lease which shall prove to be invalid,
void or illegal in no way affect, impairs or invalidates any other provision
hereof, and such other provisions shall remain in full force and effect.

form memorandum thereof without the consent of the other.

and affixed to this Lease are a part hereof.

49. MODIFICATION FOR LENDER. If, in connection with obtaining permanent
financing for the Building, the lender shall request reasonable modifications
to this Lease as a condition to such financing, Tenant will not unreasonably
withhold, delay or defer its consent thereto, provided that such modifications
do not increase the obligations of Tenant hereunder or materially adversely
affect the leasehold interest hereby created or Tenant's rights hereunder.

50. ACCORD AND SATISFACTION. No payment by Tenant or receipt by Landlord of a
lesser amount than the Rent payment herein stipulated shall be deemed to be
other than on account of the Rent, nor shall any endorsement or statement on
any check or any letter accompanying any check or payment as Rent be deemed an
accord and satisfaction, and Landlord's right to recover the balance of such
Rent or pursue any other remedy provided in this Lease.

     Tenant agrees that each of the foregoing covenants and agreements shall be
applicable to any covenant or agreement either expressly contained in this
Lease or imposed by any statute or a common law.

     IN WITNESS WHEREOF, the parties have executed the Lease as of the date

                              Work Letter Agreement


Ladies and Gentlemen:

You (hereinafter called "Tenant") and we (hereinafter called "Landlord") are
executing simultaneously with this Work Letter Agreement, a written lease (the
"Lease") covering those certain premises more particularly described in Exhibit
"A" to the Lease, (hereinafter referred to as the "Premises") in the building
addressed at 400 Mercer St., Seattle, Washington 98109.

To induce Tenant to enter into the Lease (which is hereby incorporated by
reference to the extent that the provisions of this Agreement may apply
thereto) and in consideration of the mutual covenants hereinafter contained,
Landlord and Tenant mutually agree as follows:

1. TENANT'S PLANS AND SPECIFICATIONS.

        a. Except to the extent otherwise provided in Subparagraph 1.b. and
1.c., Landlord agrees that, at its sole cost and expense, through its architect
or space planner, Landlord will furnish all architectural, mechanical and
electrical engineering plans required for the performance of the work
(hereinafter referred to as "Building Standard Work", Exhibit "B-1")
hereinbelow described, including complete detailed plans and specifications for
Tenant's partition layout, reflected ceiling, heating and air conditioning,
electrical outlets and switches and telephone outlets.

        b. It is understood and agreed that Tenant may require work
(hereinafter referred to as "Building Nonstandard Work") different from or in
addition to the Building Standard Work. In such event, any architectural,
mechanical, electrical and plumbing plans and specifications required shall be
furnished, at Tenant's sole cost and expense, by Landlord's architect or 
space planner.

        c. It is understood and agreed that any interior decorating service,
such as selection of wall paint colors and/or wall coverings, fixtures,
carpeting, and any or all other decorator items required by Tenant in the
performance of said work referred to hereinabove in Subparagraphs 1.a. and 1.b.
shall be at Tenant's sole cost and expense.

        d. It is understood and agreed that all plans and specifications
referred to hereinabove Subparagraphs 1.a. and 1.b. are subject to Landlord's
approval, which Landlord agrees shall not be unreasonably withheld.

2. BUILDING STANDARD WORK AT LANDLORD'S COST AND EXPENSE.

        Landlord agrees, at its sole cost and expense to furnish and install
all of the following "Building Standard Work" limited to the quantities and/or
dollar amount specified on the attached Exhibit "B-1", and as selected and
specified by Landlord and as indicated on Tenant's final approved plans.

                                       18
<PAGE>   20
3. BUILDING NONSTANDARD WORK AT TENANT'S COST AND EXPENSE.

        Provided Tenant's plans and specifications are furnished by the date
required hereinabove in Subparagraph 1.c., Landlord shall cause Tenant's
"Building Nonstandard Work" to be installed by Landlord's contractor, but at
Tenant's sole cost and expense. Prior to commencing any such work, Landlord,
its contractor, or its architects shall submit to Tenant a written estimate of
the cost thereof. If Tenant fails to provide to Landlord written notice of its
approval of such costs within five (5) days after submission thereto to Tenant,
such failure shall be deemed a disapproval thereof, and Landlord's contractor
shall not proceed with such work.

4. SUBSTITUTION AND CREDITS.

        Tenant may, with Landlord's approval and provided that Landlord has not
previously purchased said material, select different new materials (except
window coverings) in place of "Building Standard Work" materials which would
otherwise be initially furnished and installed by Landlord for or in the
interior of the Premises under the provisions of this Work Letter Agreement,
provided such selection is indicated on said Tenant's final plans. If Tenant
shall make any such selection and if the cost of such different new materials
of Tenant's selection shall exceed Landlord's cost of the "Building Standard
Work" materials thereby replaced, Tenant shall pay to Landlord, as hereinafter
provided, the difference between the cost of such different new materials and
the credit given by Landlord for the materials thereby replaced.

        No such different new materials shall be furnished and installed in
replacement for any of Landlord's "Building Standard Work" materials until
Landlord or its contractor and/or its architect or space planner shall have
advised Tenant in writing of, and Landlord or this contractor and/or its
architect or space planner have agreed in writing on, the cost of such
different materials and Landlord's cost of such replaced Landlord's "Building
Standard Work" materials.

One hundred percent (100%) of all amounts payable by Tenant to Landlord
pursuant to Paragraphs 3. and 4. of this Work Letter Agreement shall be paid by
Tenant upon Tenant's execution of the written estimate for the work required.

5. COMPLETION AND RENTAL COMMENCEMENT DATE.

        It is agreed that Tenant's obligation for the payment of rent under the
Lease shall not commence until Landlord has substantially completed all work to
be performed by Landlord as hereinabove set forth in Paragraphs 2. and 3.;
provided, however, that if Landlord shall be delayed in substantially
completing said work as a result of:

        a. Tenant's failure to furnish plans and specifications in accordance
with the date specified hereinabove in Subparagraph 1.c.; or

        b. Tenant's request for materials, finishes or installations other than
Landlord's "Building Standard Work"; or

        c. Tenant's changes in the said plans and specifications after their
submission to Landlord in accordance with the provisions of Subparagraph 1.c.
hereinabove; or

        d. Tenant's failure to approve estimates pursuant to Paragraph 3.
hereinabove covering "Building Nonstandard Work"; then the commencement of the
term of said lease shall be accelerated by the number of days of such delay.

        If the foregoing correctly sets forth our understanding, kindly sign
copies of this Work Letter Agreement where indicated.

1.   No sign, placard, picture, name or notice shall be installed or displayed
     on any part of the outside or inside of the Building without the prior
     written consent of Landlord. Landlord shall have the right to remove, at
     Tenant's expense and without notice, any sign installed or displayed in
     violation of this rule. All approved signs or lettering on doors and walls
     shall be printed, painted, affixed or inscribed at the expense of Tenant
     by a person chosen by Landlord.

2.   If Landlord objects in writing to any curtain, blinds, shades, screens or

     prevent access thereto of all persons whose presence in the judgment of
     Landlord would be prejudicial to the safety, character, reputation and
     interest of the Building and its tenants; provided that nothing herein
     contained shall be construed to prevent such access to persons with whom
     any tenant normally deals in the ordinary course of its business, unless
     such persons are engaged in illegal activities. No tenant and no employee
     or invitee of any tenant shall go upon the roof of the Building.

4.   The directory of the Building will be provided exclusively for the display
     of the name and location of Tenants only, and Landlord reserves the right
     to exclude any other names therefrom.

     the Building for the purpose of cleaning the same. Tenant shall not
     cause any unnecessary labor by carelessness or indifference to the good
     order and cleanliness of the Premises. Landlord shall not in any way be
     responsible to any Tenant for any loss of property on the Premises,
     however occurring, or for any damage to any Tenant's property by the
     janitor or any other employee or any other person.

6.   Landlord will furnish to Tenant, free of charge, two keys to each door lock
     in the Premises. Landlord may make a reasonable charge for any additional
     keys. Tenant shall not make or have made additional keys, and Tenant shall
     not alter any lock or install a new additional lock or bolt on any door of
     its Premises. Tenant, upon termination of its tenancy, shall deliver to
     Landlord the keys of all doors which have been furnished to Tenant, and in
     the event of loss of any key so furnished, shall pay Landlord therefor.

     services, it shall first obtain, and comply with, Landlord's instructions
     in their installation.

8.   Any freight elevator shall be available for use by all tenants in the
     Building, subject to such reasonable scheduling as Landlord in its
     discretion shall deem appropriate. No equipment, materials, packages,

     or carried in the elevators except between such hours and in such elevators
     as may be designated by Landlord.

9.   Tenant shall not place a load on any floor of the Premises which exceeds

     to properly distribute the weight. Business machines and mechanical
     equipment belonging to Tenant, which cause noise or vibration that may be

     any tenants in the Building, shall be placed and maintained by Tenant, at
     Tenant's expense, on vibration eliminators or other devices sufficient to
     eliminate noise or vibration. The persons employed to move such equipment
     in or out of the Building must be acceptable to Landlord. Landlord will not
     be responsible for loss of, or damage to, any such equipment or other
     property from any cause, and all damage done to the Building by maintaining
     or moving such equipment or other property shall be repaired at the expense
     to Tenant.

     foul or noxious gas or substance, or permit or allow the premises to be

     cooperate fully with Landlord to assure the most effective operation of the
     Building's heating and air conditioning and to comply with any government
     energy-saving rules, laws or regulations of which Tenant has actual notice,
     and shall refrain from attempting to adjust controls. Tenant shall keep
     corridor doors closed, and shall close window coverings at the end of each
     business day.

13.  Landlord reserves the right, exercisable without notice and without
     liability to Tenant, to change the name and street address of the Building.

14.  Landlord reserves the right to exclude from the Building between the hours
     of 6 p.m. and 7 a.m. the following day, or such other hours as may be
     established from time to time by Landlord, and on Sundays and legal
     holidays, any person unless that person is known to the person or employee
     in charge of the Building and has a pass or is properly identified. Tenant
     shall be responsible for all persons for whom it requests passes and shall
     be liable to Landlord for all acts of such persons. Landlord reserves the

     all water faucets or other water apparatus, and electricity, gas or air
     outlets before Tenant and its employees leave the Premises. Tenant shall be
     responsible for any damage or injuries sustained by other tenants or

                                   EXHIBIT D

                      STANDARDS FOR UTILITIES AND SERVICES


The following Standards for Utilities and Services are in effect. Landlord
reserves the right to adopt nondiscriminatory modifications and additions
hereto:

As long as Tenant is not in default under any of the terms, covenants,
conditions, provisions or agreements of this Lease, Landlord shall:

        (a) Provide non-attended automatic elevator facilities Monday through
Friday, except holidays, from 3 A.M. to 6 P.M. and have one elevator available
at all other times.

        (b) Ventilate the Premises and furnish air conditioning or heating as
may be required for the comfortable occupancy of the Premises. The air
conditioning system achieves maximum cooling when the window coverings are
closed. Landlord shall not be responsible for room temperatures if Tenant does
not keep all window covering in the Premises closed whenever the system is in
operation. Tenant agrees to cooperate fully at all times with Landlord, and to
abide by all regulations and requirements which Landlord may prescribe for the
proper function and protection of said air conditioning system. Tenant agrees
not to connect any apparatus, device, conduit or pipe to the Building chilled
and hot water air conditioning supply lines. Tenant further agrees that neither
Tenant nor its servants, employees, agents, visitors, licensees or contractors
shall at any time enter mechanical installations or facilities of the Building
or adjust, tamper with, touch or otherwise in any manner affect said
installations or facilities.

        (c) Landlord shall furnish to the Premises, at all times, rather than
normal business hours on normal business days, electric current as required by
the Building standard office lighting and fractional horsepower office business
machines and computer equipment. Tenant agrees its electrical consumption
extends beyond normal business hours, and as such shall reimburse Landlord not
more than $300.00 monthly for the additional consumption. Tenant agrees not to
use any apparatus or device in, or upon, or about the Premises which may in any
way increase the amount of such services agreed to be furnished or supplied to
said Premises, and Tenant further agrees not to connect any apparatus or device
with wires, conduits or pipes, or other means by which such services are
supplied, for the purpose of using additional or unusual amounts of such
services without written consent of Landlord. Should Tenant use the same to
excess, the refusal on the part of Tenant to pay upon demand of Landlord the
amount established by Landlord for such excess charge shall constitute a breach
of the obligation to pay rent under this Lease and shall entitle Landlord to the
rights therein granted for such breach. At all times Tenant's use of electric
current shall never exceed the capacity of the feeders to the Building or the
risers or wiring installation and Tenant shall not install or use or permit the
installation or use of any computer or electronic data processing equipment in
the Premises without the prior written consent of Landlord.

        (d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses or consumes water for any purposes
in addition to ordinary drinking and lavatory purposes of which fact Tenant
constitutes Landlord to be the sole judge, Landlord may install a water meter
and thereby measure Tenant's water consumption for all purposes. Tenant shall
pay Landlord for the cost of the meter and the cost of the installation thereof
and throughout the duration of Tenant's occupancy Tenant shall keep said meter
and installation equipment in good working order and repair at Tenant's own
cost and expense, in default of which Landlord may cause such meter and
equipment to be replaced or repaired and collect the cost thereof from Tenant.
Tenant agrees to pay for water consumed, as shown on said meter, as and when
bills are rendered, and on default in making such payment, Landlord may pay
such charges and collect the same from Tenant. Any such costs or expenses
incurred, or payments made by Landlord for any of the reasons or purposes
hereinabove stated shall be deemed to be additional rent payable by Tenant and
collectible by Landlord as such.

        (e) Provide janitor service to the Premises, provided the same are
used, exclusively as offices, and are kept reasonably in order by Tenant, and
if to be kept clean by Tenant, no one other than persons approved by Landlord
shall be permitted to enter the Premises for such purposes. If the Premises are
not used exclusively as offices, they shall be kept clean and in order by
Tenant, at Tenant's expense, and to the satisfaction of Landlord, and by
persons approved by Landlord, Tenant shall pay to Landlord the cost of removal
of any of Tenant's refuse and rubbish usually attendant upon the use if the
Premises as offices.

                                       24

Landlord reserves the right to stop services of the elevator, plumbing,
ventilation, air conditioning and electric systems, when necessary, by reason
of accident or emergency or for repairs, alterations or improvements, in the
judgment of Landlord, desirable or necessary to be made, until said repairs,
alterations or improvements shall have been completed, and shall further have
no responsibility or liability for failure to supply elevator facilities,
plumbing, ventilating, air conditioning or electric service, when prevented
from so doing by strike or accident or by any cause beyond Landlord's
reasonable control, or by laws, rules, orders, ordinances, directions,
regulations or requirements of any federal, state, county or municipal
authority or failure of gas, oil or other suitable fuel supply or inability by
exercise of reasonable diligence to obtain gas, oil or other suitable fuel. It
is expressly understood and agreed that any covenants on Landlord's part to
furnish any service pursuant to any of the terms, covenant, conditions,
provisions or agreements of this Lease, or to perform any act or thing for the
benefit of Tenant, shall not be deemed breached if Landlord is unable to
furnish or perform the same by virtue of a strike or labor trouble or any other
cause whatsoever beyond Landlord's control. However, Landlord shall give Tenant
advance notice of interruption of electrical or HVAC service if such
interruption is caused by other than an accident or emergency.

part of the building and the systems and equipment thereof; whether requiring

defective condition in the premises for which Owner may be responsible
hereunder. There shall be no allowance to Tenant for diminution of rental value
and no liability on the part of Owner by reason of inconvenience, annoyance or
injury to business arising from Owner or others making repairs, alterations,
additions or improvements in or to any portion of the building or the demised
premises or in and to the fixtures, appurtenances or equipment thereof. It is
specifically agreed that Tenant shall not be entitled to any setoff or
reduction of rent by reason of any failure of Owner to comply with the
convenants of this or any other article of this Lease. Tenant agrees that

damages for breach of contract. The provisions of this Article 4 shall not apply
in the case of fire or other casualty which are dealt with in Article 9 hereof.

possession, and at all times thereafter, Tenant, at Tenant's sole cost and
expense, shall promptly comply with all present and future laws, orders and
regulations of all state, federal, municipal and local governments,
departments, commissions and boards and any direction of any public officer

Fire Underwriters, Insurance Services Office, or any similar body which shall
impose any violation, order or duty upon Owner or Tenant with respect to the

<PAGE>   3
use or manner of use of the premises or the building (including the use
permitted under the lease). Nothing herein shall require Tenant to make
structural repairs or alterations unless Tenant has, by its manner of use of the
demised premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto.
Tenant may, after securing Owner to Owner's satisfaction against all damages,
interest, penalties and expenses, including, but not limited to: reasonable
attorney's fees, by cash deposit or by surety bond in an amount and in a company
satisfactory to Owner, contest and appeal any such laws, ordinances, orders,
rules, regulations or requirements provided same is done with all reasonable
promptness and provided such appeal shall not subject Owner to prosecution for a
criminal offense or constitute a default under any lease or mortgage under which
Owner may be obligated, or cause the demised premises or any part thereof to be
condemned or vacated. Tenant shall not do or permit any act or thing to be done
in or to the demised premises which is contrary to law, or which will invalidate
or be in conflict with public liability, fire or other policies of insurance at

premises or the building of which the demised premises form a part, or which
shall or might subject Owner to any liability or responsibility to any person or
for property damage. Tenant shall not keep anything in the demised premises

Tenant's occupancy. Tenant shall pay all costs, expenses, fines, penalties, or
damages, which may be imposed upon Owner by reason of Tenant's failure to comply
with the provisions of this article and if by reason of such failure the fire
insurance rate shall, at the beginning of this lease or at any time thereafter,
be higher than it otherwise would be, then Tenant shall reimburse Owner, as
additional rent hereunder, for that portion of all fire insurance premiums
thereafter paid by Owner which shall have been charged because of such failure
by Tenant. In any section or proceeding wherein Owner and Tenant are parties, a
schedule or "make-up" of rate for the building or demised premises issued by the
New York Fire Insurance Exchange, or other body making fire insurance rates
applicable to said premises shall be conclusive evidence of the facts therein
stated and of the several items and charges in the fire insurance rates then
applicable to said premises. Tenant shall not place a load upon any floor of the
demised premises exceeding the floor load per square foot area which it was
designated to carry and which is allowed by law. owner reserves the right to

        7. This lease is subject and subordinate to all ground or underlying
leases and to all mortgages which may now or hereafter affect such leases or
the real property of which demised premises are a part and to all renewals,
modifications, consolidations, replacements and extensions of any such
underlying leases and mortgages. This clause shall be self-operative and no
further instrument of subordination shall be required by any ground or
underlying lessor or by any mortgagee, affecting any lease or the real property
of which the demised premises are a part. In confirmation of such
subordination, Tenant shall execute promptly any certificate that Owner may 
request.

PROPERTY -- LOSS, DAMAGE, REIMBURSEMENT, INDEMNITY:

        8. Owner of its agents shall not be liable for any damage to property of
Tenant or of others entrusted to employees of the building, nor for loss of or
damages to any property of Tenant by theft or otherwise, nor for any injury or
damage to persons or property resulting from any cause of whatsoever nature,
unless caused by or due to the negligence of Owner, its agents, servants or
employees. Owner or its agents will not be liable for any such damage caused by
other tenants or persons in, upon or about said building or caused by
operations in construction of any private, public or quasi public work.

        If at any time any windows of the demised premises are temporarily
closed, darkened or bricked up (or permanently closed, darkened or bricked up,
if required by law) for any reason whatsoever including, but not limited to
Owner's own acts, Owner shall not be liable for any damage Tenant may sustain
thereby and Tenant shall not be entitled to any compensation therefor nor
abatement or diminution of rent, nor shall the same release Tenant from its
obligations hereunder nor constitute an eviction. Tenant shall indemnify and
save harmless Owner against and from all liabilities, obligations, damages,
penalties, claims, costs and expenses for which Owner shall not be reimbursed
by insurance, including reasonable attorneys fees, paid, suffered or incurred
as a result of any breach by Tenant, Tenant's agents, contractors, employees,
invitees, or licensees, of any covenant or condition of this lease, or the
carelessness, negligence or improper conduct of the Tenant, Tenant's agents,
contractors, employees, invitees or licensees. Tenant's liability under this
lease extends to the acts and omissions of any sub-tenant, and any agent,
contractor, employee, invitee or licensee of any sub-tenant. In case any action
or proceeding is brought against Owner by reason of any such claim, Tenant,
upon written notice from Owner, will, at Tenant's expense, resist or defend
such action or proceeding by counsel approved by Owner in writing, such
approval not to be unreasonably withheld.

DESTRUCTION, FIRE AND OTHER CASUALTY:

        9. (a) If the demised premises or any part thereof shall be damaged by
fire or other casualty, Tenant shall give immediate notice thereof to Owner and
this lease shall continue in full force and effect except as hereinafter set
forth. (b) If the demised premises are partially damaged or rendered partially
unusable by fire or other casualty, the damages thereto shall be repaired by and
at the expense of Owner and the rent, until such repair shall be substantially
completed, shall be apportioned from the day following the casualty according to
the part of the premises which is unusable. (c) If the demised premises are
totally damaged or rendered wholly unusable by fire or other casualty, then the
rent shall be proportionately paid up to the time of the casualty and
thenceforth shall cease until the date when the premises shall have been
repaired and restored by Owner, subject to Owner's right to elect not to restore
the same as hereinafter provided. (d) If the demised premises are rendered
wholly unusable or (whether or not the demised premises are damaged in whole or
in part) if the building shall be so damaged that Owner shall decide to demolish
it or to rebuild it, then, in any of such events, Owner may elect to terminate
this lease by written notice to Tenant, given within 90 days after such fire or
casualty, specifying a date for the expiration of the lease, which date shall
not be more than 60 days after the giving of such notice, and upon the date
specified in such notice the term of this lease shall expire as fully and
completely as if such date were the date set forth above for the termination of
this lease and Tenant shall forthwith quit, surrender and vacate the premises
without prejudice however, to Landlord's rights and remedies against Tenant
under the lease provisions in effect prior to such termination, and any rent
owing shall be paid up to such date and any payments of rent made by Tenant
which were on account of any period subsequent to such date shall be returned to
Tenant. Unless Owner shall serve a termination notice as provided for herein.
Owner shall make the repairs and restoration under the conditions of (b) and (c)
hereof, with all reasonable expedition, subject to delays due to adjustment of
insurance claims, labor troubles and causes beyond Owner's control. After any
such casualty, Tenant shall cooperate with Owner's restoration by removing from
the premises as promptly as reasonably possible, all of Tenant's salvageable
inventory and movable equipment, furniture, and other property. Tenant's
liability for rent shall resume five (5) days after written notice from Owner
that the premises are substantially ready for Tenant's occupancy. (e) Nothing
contained hereinabove shall relieve Tenant from liability that may exist as a
result of damage from fire or other casualty. Notwithstanding the foregoing,
each party shall look first to any insurance in its favor before making any
claim against the other party for recovery for loss or damage resulting from
fire or other casualty, and to the extent that such insurance is in force and
collectible and to the extent permitted by law, Owner and Tenant each hereby
releases and waives all right of recovery against the other or any one claiming
through or under each of them by way of subrogation or otherwise. The foregoing
release and waiver shall be in force only if both releasers' insurance policies
contain a clause providing that such a release or waiver shall not invalidate
the insurance. If, and to the extent, that such waiver can be obtained only by
the payment of additional premiums, then the party benefitting from the waiver
shall pay such premiums within ten days after written demand or shall be deemed
to have agreed that the party obtaining insurance coverage shall be free of any
further obligation under the provisions hereof with respect to waiver of
subrogation. Tenant acknowledges that Owner will not carry insurance on Tenant's
furniture and/or furnishings or any fixtures or equipment, improvements, or
appurtenances removable by Tenant and agrees that Owner will not be obligated to
repair any damage thereto or replace the same. (f) Tenant hereby waives the
provisions of Section 227 of the Real Property Law and agrees that the
provisions of this article shall govern and control in lieu thereof.

EMINENT DOMAIN

        10. If the whole or any part of the demised premises shall be acquired
or condemned by Eminent Domain for any public or quasi public use or purpose,
then and in that event, the term of this lease shall cease and terminate from
the date of title vesting in such proceeding and Tenant shall have no claim for
the value of any unexpired term of said lease and assigns to Owner, Tenant's
entire interest in any such award.

ASSIGNMENT, MORTGAGE, ETC.:

        11. Tenant, for itself, its heirs, distributees, executors,
administrators, legal representatives, successors and assigns, expressly
covenants that it shall not assign, mortgage or encumber this agreement, nor
underlet, or suffer or permit the demised premises or any part thereof to be
used by others, without the prior written consent of Owner in each instance.
Transfer of the majority of the stock of a corporate Tenant shall be deemed an
assignment. If this lease be assigned, or if the demised premises or any part
thereof be underlet or occupied by anybody other than Tenant, Owner may, after
default by Tenant, collect rent from the assignee, under-tenant or occupant,
and apply the net amount collected to the rent herein reserved, but no such
assignment, underletting, occupancy of collection shall be deemed a waiver of
this covenant, or the acceptance of the assignee, under-tenant or occupant as
tenant, or a release of Tenant from the further performance by Tenant of
covenants on the part of Tenant herein contained. The consent by Owner to an
assignment or underletting shall not in any wise be construed to relieve Tenant
from obtaining the express consent in writing of Owner to any further
assignment or underletting.

ELECTRIC CURRENTS [HAND]

        12. Rates and conditions in respect to submetering or rent inclusion, as
the case may be, to be added in RIDER attached hereto. Tenant covenants and
agrees that at all times its use of electric current shall not exceed the
capacity of existing feeders to the building or the risers or wiring
installation and Tenant may not use any electrical equipment which, in Owner's
opinion, reasonably exercised, will overload such installations or interfere
with the use thereof by other tenants of the building. The change at any time of
the character of electric service shall in no wise make Owner liable or
responsible to Tenant, for any loss, damages or expenses which Tenant may
sustain.

ACCESS TO PREMISES:

        13. Owner or Owner's agents shall have the right (but shall not be
obligated) to enter the demised premises in any emergency at any time, and, at
other reasonable times, to examine the same and to make such repairs,
replacements and improvements as Owner may deem necessary and reasonably
desirable to the demised premises or to any other portion of the building or
which Owner may elect to perform. Tenant shall permit Owner to use and maintain
and replace pipes and conduits in and through the demised premises and to erect
new pipes and conduits therein provided they are concealed within the walls,
floor, or ceiling. Owner may, during the progress of any work in the demised
premises, take all necessary materials and equipment into said premises without
the same constituting an eviction nor shall the Tenant be entitled to any
abatement of rent while such work is in progress nor to any damages by reason
of loss or interruption of business or otherwise. Throughout the term hereof
Owner shall have the right to enter the demised premises at reasonable hours
for the purpose of showing the

- - -----------
[HAND] Rider to be added if necessary.

                                                                   A-2
<PAGE>   4
same to prospective purchasers or mortgagees of the building, and during the
last six months of the term for the purpose of showing the same to prospective
tenants. If Tenant is not present to open and permit an entry into the premises,
Owner or Owner's agents may enter the same whenever such entry may be necessary
or permissible by master key or forcibly and provided reasonable care is
exercised to safeguard Tenant's property, such entry shall not render Owner or
its agents liable therefor, nor in any event shall the obligations of Tenant
hereunder be affected. If during the last month of the term Tenant shall have
removed all or substantially all of Tenant's property therefrom Owner may
immediately enter, alter, renovate or redecorate the demised premises without
limitation or abatement of rent, or incurring liability to Tenant for any
compensation and such act shall have no effect on this lease or Tenant's
obligations hereunder.

Vault, Vault Space, Area:

14. No Vaults, vault space or area, whether or not enclosed or covered, not
within the property line of the building is leased hereunder, anything contained
in or indicated on any sketch, blue print or plan, or anything contained
elsewhere in this lease to the contrary notwithstanding. Owner makes no
representation as to the location of the property line of the building. All
vaults and vault space and all such areas not within the property line of the
building, which Tenant may be permitted to use and/or occupy, is to be used
and/or occupied under a revocable license, and if any such license be revoked,
or if the amount of such space or area be diminished or required by any federal,
state or municipal authority or public utility, Owner shall not be subject to
any liability nor shall Tenant be entitled to any compensation or diminution or
abatement of rent, nor shall such revocation, diminution or requisition be
deemed constructive or actual eviction. Any tax, fee or charge of municipal
authorities for such vault or area shall be paid by Tenant.

Occupancy:

15. Tenant will not at any time use or occupy the demised premises in violation
of the certificate of occupancy issued for the building of which the demised
premises are a part. Tenant has inspected the premises and accepts them as is,
subject to the riders annexed hereto with respect to Owner's work, if any. In
any event, Owner makes no representation as to the condition of the premises and
Tenant agrees to accept the same subject to violations, whether or not of
record.

Bankruptcy:

16. (a) Anything elsewhere in this lease to the contrary notwithstanding, this
lease may be cancelled by Owner by the sending of a written notice to Tenant
within a reasonable time after the happening of any one or more of the following
events: (1) the commencement of a case in bankruptcy or under the laws of any
state naming Tenant as the debtor; or (2) the making by Tenant of an assignment
or any other arrangement for the benefit of creditors under any state statute.
Neither Tenant nor any person claiming through or under Tenant, or by reason of
any statute or order of court, shall thereafter be entitled to possession of the
premises demised but shall forthwith quit and surrender the premises. If this
lease shall be assigned in accordance with its terms, the provisions of this
Article 16 shall be applicable only to the party then owning Tenant's interest
in this lease.

    (b) it is stipulated and agreed that in the event of the termination of this
lease pursuant to (a) hereof, Owner shall forthwith, notwithstanding any other
provisions of this lease to the contrary, be entitled to recover from Tenant as
and for liquidated damages an amount equal to the difference between the rent
reserved hereunder for the unexpired portion of the term demised and the fair
and reasonable rental value of the demised premises for the same period. In the
computation of such damages the difference between any installment of rent
becoming due hereunder after the date of termination and the fair and reasonable
rental value of the demised premises for the period for which such installment
was payable shall be discounted to the date of termination at the rate of four
percent (4%) per annum. If such premises or any part thereof be relet by the
Owner for the unexpired term of said lease, or any part thereof, before
presentation of proof of such liquidated damages to any court, commission or
tribunal, the amount of rent reserved upon such reletting shall be deemed to be
the fair and reasonable rental value for the part or the whole of the premises
so re-let during the term of the re-letting. Nothing herein contained shall
limit or prejudice the right of the Owner to prove for and obtain as liquidated
damages by reason of such termination, an amount equal to the maximum allowed
by any statute or rule of law in effect at the time when, and governing the
proceedings in which, such damages are to be proved, whether or not such amount
be greater, equal to, or less than the amount of the difference referred to
above.

Defaults:

17. (1) If Tenant defaults in fulfilling any of the covenants of this lease
other than the covenants for the payment of rent or additional rent; or if the
demised premises become vacant or deserted; or if any execution or attachment
shall be issued against Tenant or any of Tenant's property whereupon the demised
premises shall be taken or occupied by someone other than Tenant; or if this
lease be rejected under Section 235 of Title 11 of the U.S. Code (bankruptcy
code); or if Tenant shall fail to move into or take possession of the premises
within fifteen (15) days after the commencement of the term of this lease, then,
in any one or more of such events, upon Owner serving a written five (5) days
notice upon Tenant specifying the nature of said default and upon the expiration
of said five (5) days, if Tenant shall have failed to comply with or remedy such
default, or if the said default or omission complained of shall be of a nature
that the same cannot be completely cured or remedied within said five (5) day
period, and if Tenant shall not have diligently commenced curing such default
within such five (5) day period, and shall not thereafter with reasonable
diligence and in good faith, proceed to remedy or cure such default, then Owner
may serve a written three (3) days' notice of cancellation of this lease upon
Tenant, and upon the expiration of said three (3) days this lease and the term
thereunder shall end and expire as fully and completely as if the expiration of
such three (3) day period were the day herein definitely fixed for the end and
expiration of this lease and the term thereof and Tenant shall then quit and
surrender the demised premises to Owner but Tenant shall remain liable as
hereinafter provided.

    (2) If the notice provided for is (1) hereof shall have been given, and the
term shall expire as aforesaid; or if Tenant shall make default in the payment
of the rent reserved herein or any item of additional rent herein mentioned or
any part of either or in making any other payment herein required; then and in
any of such events Owner may without notice, re-enter the demised premises
either by force or otherwise, and dispossess Tenant by summary proceedings or
otherwise, and the legal representative of Tenant or other occupant of demised
premises and remove their effects and hold the premises as if this lease had not
been made, and Tenant hereby waives the service of notice of intention to
re-enter or to institute legal proceedings to that end. If Tenant shall make
default hereunder prior to the date fixed as the commencement of any renewal or
extension of this lease, Owner may cancel and terminate such renewal or
extension agreement by written notice.

Remedies of Owner and Waiver of Redemption:

18. In case of any such default, re-entry, expiration and/or dispossess by
summary proceedings or otherwise, (a) the rent shall become due thereupon and be
paid up to the time of such re-entry, dispossess and/or expiration, (b) Owner
may re-let the premises or any part or parts thereof, either in the name of
Owner or otherwise, for a term or terms, which may at Owner's option be less
than or exceed the period which would otherwise have constituted the balance of
the term of this lease and may grant concessions or free rent or charge a higher
rental than that in this lease, and/or (c) Tenant or the legal representatives
of Tenant shall also pay Owner as liquidated damages for the failure of Tenant
to observe and perform said Tenant's covenants herein contained, any deficiency
between the rent hereby reserved and/or covenanted to be paid and the net
amount, if any, of the rents collected on account of the lease or leases of the
demised premises for each month of the period which would otherwise have
constituted the balance of the term of this lease. The failure of Owner to
re-let the premises or any part or parts thereof shall not release or affect
Tenant's liability for damages. In computing such liquidated damages there shall
be added to the said deficiency such expenses as Owner may incur in connection
with re-letting, such as legal expenses, attorneys' fees, brokerage, advertising
and for keeping the demised premises in good order or for preparing the same for
re-letting. Any such liquidated damages shall be paid in monthly installments by
Tenant on the rent day specified in this lease and any suit brought to collect
the amount of the deficiency for any month shall not prejudice in any way the
rights of Owner to collect the deficiency for any subsequent month by a similar
proceeding. Owner, in putting the demised premises in good order or preparing
the same for re-rental may, at Owner's option, make such alterations, repairs,
replacements, and/or decorations in the demised premises as Owner, in Owner's
sole judgement, considers advisable and necessary for the purpose of re-letting
the demised premises, and the making of such alterations, repairs, replacements,
and/or decorations shall not operate or be construed to release Tenant from
liability hereunder as aforesaid. Owner shall in no event be liable in any way
whatsoever for failure to re-let the demised premises, or in the event that the
demised premises are re-let, for failure to collect the rent thereof under such
re-letting, and in no event shall Tenant be entitled to receive any excess, if
any, of such net rents collected over the terms payable by Tenant to Owner
hereunder. In the event of a breach or threatened breach by Tenant of any of the
covenants or provisions hereof. Owner shall have the right of injunction and the
right to invoke any remedy allowed at law or in equity as if re-entry, summary
proceedings and other remedies were not herein provided for. Mention in this
lease of any particular remedy, shall not preclude Owner from any other remedy,
in law or in equity. Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws in the event of Tenant
being evicted or dispossessed for any cause, or in the event of Owner obtaining
possession of demised premises, by reason of the violation by Tenant of any of
the covenants and conditions of this lease, or otherwise.

Fees and Expenses

19. If Tenant shall default in the observance or performance of any term or
covenant on Tenant's part to be observed or performed under or by virtue of any
of the terms or provisions in any article of this lease, then, unless otherwise
provided elsewhere in this lease, Owner may immediately or at any time
thereafter and without notice perform the obligation of Tenant thereunder. If
Owner, in connection with the foregoing or in connection with any default by
Tenant in the covenant to pay rent hereunder, makes any expenditures or incurs
any obligations for the payment of money, including but not limited to
attorney's fees, in instituting, prosecuting or defending any action or
proceeding, then Tenant will reimburse Owner for such sums so paid or
obligations incurred with interest and costs. The foregoing expenses incurred
by reason of Tenant's default shall be deemed to be additional rent hereunder
and shall be paid by Tenant to Owner within five (5) days of rendition of any
bill or statement to Tenant therefor. If Tenant's lease term shall have expired
at the time of making of such expenditures or incurring of such obligations,
such sums shall be recoverable by Owner as damages.

Building Alterations and Management:

20. Owner shall have the right at any time without the same constituting an
eviction and without incurring liability to Tenant therefor to change the
arrangement and/or location of public entrances, passageways, doors, doorways,
corridors, elevators, stairs, toilets or other public parts of the building and
to change the name, number or designation by which the building may be known.
There shall be no allowance to Tenant for diminuation of rental value and no
liability on the part of Owner by reason of inconvenience, annoyance or injury
to business arising from Owner or other Tenants making any repairs in the
building or any such alterations, additions and improvements. Furthermore,
Tenant shall not have any claim against Owner by reason of Owner's imposition of
such controls of the manner of access to the building by Tenant's social or
business visitors as the Owner may deem necessary for the security of the
building and its occupants.

No Representation by Owner:

21. Neither Owner nor Owner's agents have made any representations or promises
with respect to the physical condition of the building, the land upon which

HYDRATION TECHNOLOGY CORPORATION AS TENANT AND 654 MADISON AVENUE COMPANY AS

37. Electricity: (a) Electricity used by Tenant in the Demised Premises shall be
furnished by Landlord to Tenant on a "rent inclusion" basis. There shall be no
separate or specific charge to Tenant for such electricity whether by meter
charge or otherwise, such electric energy being thus included in the annual
rental as hereinafter provided. Landlord shall not in any way be liable or
responsible to Tenant for any loss or damage or expense which Tenant may sustain
or incur if either the quantity or character of electric service is changed,
unless the same results from the negligence of Landlord.

                   (b) If the public utility rate schedule for the supply of
electric current to the Building shall be increased or decreased or if there
shall be a change in taxes or if additional taxes shall be imposed upon the sale
or furnishing of such electric current, or if Tenant's failure to maintain its
machinery and equipment in good order and repair causes greater consumption of
electrical current, or if Tenant adds substantially to any machinery, appliances
or equipment, the annual rent reserved shall be equitably adjusted to reflect
the resulting increase or decrease in such use. If Landlord and Tenant cannot
agree thereon, the amounts of such adjustments shall be determined, based on
standard practices, by an independent electrical engineer to be mutually agreed
upon by Landlord and Tenant and paid for equally by both parties. When the
amounts of such adjustments are so determined, the parties shall execute an
agreement supplementary hereto to reflect such adjustments in the amount of the
annual rental stated in this Lease effective from the date of the increase or
decrease in the public utility rate schedule; but such adjustments shall be
effective from such date whether or not such a supplementary agreement is
executed.

                   (c) Landlord reserves the right to discontinue furnishing
electric energy to Tenant in the Demised Premises at any time upon not less than
thirty (30) days' notice to Tenant. If Landlord exercises such right to
termination, this Lease shall continue in full force and effect and shall be
unaffected thereby, except only that, from and after the effective date of such
termination, Landlord shall not be obligated to furnish electric energy to
Tenant. If Landlord so discontinues furnishing electric energy to Tenant,
Landlord shall arrange at Landlord's cost and expense to obtain electric service
directly from the public utility company servicing the Building utilizing the
then existing electric feeders, risers and wiring serving the Demised Premises.
Commencing when Tenant receives such direct service the fixed annual rental rate
payable under this Lease shall be reduced to $19,140 per annum.

                   (d) Landlord shall not be liable to Tenant for any loss or
damage or expense which Tenant may sustain or incur if either the quantity or
character of electric service is changed or is no longer available or suitable
for Tenant's requirements. Tenant covenants and agrees that at all times its use
of electric current shall never exceed the capacity of existing feeders to the
building or the risers or wiring installation.

39. The term "Operating Expenses" as used herein shall mean any and all costs
and expenses (except real estate taxes) paid, incurred, or charged by Landlord
in connection with the operation, servicing and maintenance of the Building. In
the event that the operating expenses incurred by Landlord for any calendar year
following the base year shall exceed the operating expenses incurred by Landlord
during the base year, tenant shall pay to the Landlord as additional rent for
such calendar year an amount equal to the Percentage of the excess. On or after
the first of the year subsequent to the calendar year following the base year
and on or after the first of each calendar year thereafter, Landlord shall
furnish to Tenant a statement of the operating expenses for the preceding
calendar year. If the operating expenses for the preceding calendar year exceed
the operating expenses for the base year, additional rent in an amount equal to
The Percentage of the excess shall be due from Tenant to Landlord, and such
additional rent shall be payable by Tenant to Landlord within thirty days after
receipt of the aforesaid statement.

     For the purpose of this article, the Base year shall mean the calendar year
     1994.

     The Percentage for the purposes of this article shall mean 0.62%.

40. Tenant is advised that Landlord is the owner of a leasehold dated March 12,
1959 on the entire premises and the Tenant hereunder covenants and agrees that
the present lease is made expressly subject to all the terms, provisions,
covenants and conditions of the said Master Lease insofar as same may apply to
the Tenant hereunder and the premises herein described.

Landlord represents that it has complied with all the terms, provisions,
covenants and conditions of said Master Lease and that this Lease is in no way
inconsistent or violative of the terms, provisions, covenants and conditions of

Landlord's Protective Liability endorsement attached hereto. The insurance
policy provided by Lessee shall name Nelson Northwest, Inc. and John E. Nelson
and Jania M. Nelson, his wife, as additional insureds.

                8.3 Waiver of Subrogation. Tenant and Landlord each waives any
and all right of recovery against the other, or against the officers, employees,
agents and representatives of the other, for loss of or damage to such waiving
party or its property or the property of others under its control, where such
loss or damage is insured against by a fire policy whether or not such policy is
in force at the time of such loss or damage, provided that this section shall be
of no force or effect if its inclusion in this Lease would negate the insurance
coverage of Landlord and Tenant. Tenant shall be solely responsible for any
deductible claimed arising out of loss caused by Tenant's acts or omissions.

                8.4 Hold Harmless. Tenant shall indemnify, defend and hold
Landlord harmless from any and all claims arising from Tenant's use of the
Premises or from the conduct of its business or from any activity, work or
things which may be permitted or suffered by Tenant in or about the Premises and
shall further indemnify, defend and hold Landlord harmless from and against any
and all claims arising from any breach or default in the performance of any
obligation on Tenant's part to be performed under the provisions of this Lease
or arising from any negligence of Tenant or any of its agents, contractors,
employees or invitees. Tenant hereby assumes all risk of damage to property or
injury to person in or about the Premises from any cause, and Tenant hereby
waives all claims in respect thereof against Landlord, excepting where said
damage or injury arises out of negligence of Landlord, its agents, contractors,
employees or invitees or from a breach by Landlord of any of its obligations
imposed hereunder.

                8.5 Exemption of Landlord from Liability, Tenant hereby accepts
the Premises "as is" and agrees that (1) Landlord shall not be liable for
injury to Tenant's business or any loss of income therefrom or for damage to
the goods, wares, merchandise or other property of Tenant, Tenant's employees,
invitees, customers, or any other person in or about the Premises; nor, unless
through its negligence, (2) shall Landlord be liable for injury to the person
of Tenant, Tenant's employees, agents or contractors and invitees, whether such
damage or injury is caused by or results from fire, steam, electricity, gas,
water or rain, or from the breakage, leakage, obstruction or other defect of
pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting
fixtures, or from any other cause, whether the said damage or injury results
from conditions arising upon the Premises or upon other portions of the
building of which the Premises are a part, or from other sources or places, and
regardless of whether the cause of such damage or injury or the means of 
repairing the same is inaccessible to Landlord or Tenant. Landlord shall not be
liable for any damages arising from any act or neglect of any other tenant, if
any, of the building in which the Premises are located.

(1)      Except for damage arising from the negligence or intentional misconduct
         of the Landlord, its agents, or employees.

                  8.7.2 If any of Tenant's said personal property shall be
assessed with Landlord's real property, Tenant shall pay Landlord the taxes
attributable to Tenant within ten (10) days after receipt from Landlord of a
written statement.

     13. GENERAL PROVISIONS.

         13.1 Estoppel Statement.

                  13.1.1 Tenant shall at any time upon not less than ten (10)
days' prior written notice from Landlord execute, acknowledge and deliver to
Landlord a statement in writing (i) certifying that this Lease is unmodified and
in full force and effect (or, if modified, stating the nature of such
modification and certifying that this Lease, as so modified, is in full force
and effect) and the date to which the rent, security deposit, and other
charges are paid in advance, if any, and (ii) acknowledging that there are not,
to Tenant's knowledge, any uncured defaults on the part of Landlord hereunder,
or specifying such defaults, if any, which are claimed. Any such statement may
be conclusively relied upon by any prospective purchaser or encumbrances of the
Premises.

                  13.1.2 Tenant's failure to deliver such statement within such
time shall be conclusive upon Tenant (i) that this Lease is in full force and
effect, without modification except as may be represented by Landlord, (ii) that
there are no uncured defaults in Landlord's performance, and (iii) that not more
than one (1) month's rent has been paid in advance.

         13.2 Landlord's Interests. The term "Landlord" as used herein shall
mean only the owner or owners at the time in question of the fee title or a
tenant's interest in ground lease of the Premises. In the event of any transfer
of such title or interest, Landlord herein named (and in case of any subsequent
transfers, the then grantor) shall be relieved from and after the date of such
transfer of all liability as respects Landlord's obligations thereafter to be
performed, provided that any funds in the hands of Landlord or the then grantor
at the time of such transfer, in which Tenant has an interest, shall be
delivered to the grantee. The obligations contained in this Lease to be
performed by Landlord shall, subject as aforesaid, be binding on Landlord's
successors and assignee, only during their respective periods of ownership.

         13.3 Severability. The invalidity of any provision of this Lease, as
determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provisions hereof.

         13.4 Time of Essence. Time is of the essence.

         13.6 Incorporation of Prior Agreements; Amendments. This Lease contains

effective. This Lease may be modified in writing only, signed by the parties in
interest at the time of the modification.

<PAGE>   10

         13.7 Waivers. No waiver by Landlord or Tenant of any provision hereof
shall be deemed a waiver of any other provision hereof or of any subsequent
breach by Tenant or Landlord of the same or any other provision. Landlords
consent to or approval of any act shall not be deemed to render unnecessary the
obtaining of Landlord's consent to or approval of any subsequent act by Tenant.
The acceptance of rent hereunder by Landlord shall not be a waiver of any
preceding breach by Tenant of any provision hereof, other than the failure of
Tenant to pay the particular rent so accepted, regardless of Landlord's
knowledge of such preceding breach at the time of acceptance of such rent.

         13.8 Recording. Landlord and Tenant shall not record this Lease. Any
such recordation shall be a breach under this Lease. Tenant may record a short
form or memorandum of lease and Landlord agrees to execute the same upon
request.

         13.9 Holding Over. If Tenant remains in possession of the Premises or
any part thereof after the expiration of the term hereof, with the consent
of Landlord, such occupancy shall be a tenancy from month-to-month at a rental
set by Landlord not to exceed the amount of the last monthly rental plus fifteen
percent (15%), and all other charges payable hereunder, and upon the terms
hereof applicable to month-to-month tenancy. If Tenant remains in possession
without Landlord's approval, the rental shall be twice the amount of the last
monthly rental plus all other charges.

         13.10 Cumulative Remedies. No remedy or election hereunder shall be
deemed exclusive, but shall, wherever possible, be cumulative with all other
remedies at law or in equity.

         13.11 Binding Effect; Choice of Law. This Lease shall bind the parties,
their personal representatives, successors and assigns. This Lease shall be
governed by the laws of the state where the Premises are located.

         13.12 Subordination.

                  13.12.1 This Lease, at Landlord's option, shall be subordinate
to any ground lease, mortgage, deed of trust, or any other hypothecation for
security now or hereafter placed upon the real property of which the Premises
are a part and to any and all advance made on the security thereof and to all
renewals, modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Tenant's right to quiet possession of the
Premises shall not be disturbed if Tenant is not in default and so long as
Tenant shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. Tenant's
right to quiet enjoyment hereunder shall be specified in any document requested
by Landlord.

                  13.12.2 Tenant agrees to execute any documents required to
effectuate such subordination or to make this Lease prior to the lien of any
mortgage, deed of trust or ground lease, as the case may be, and failing to do
so within ten (10) days after written demand does hereby make, constitute and
irrevocably appoint Landlord as Tenant's attorney in fact and in Tenant's name,
place and stead, to do so.

         13.13 Landlord's Access. Landlord and Landlord's agents shall have the
right to enter the Premises at reasonable

times for the purpose of inspecting the same, showing the same to prospective
purchasers or lenders, and making such alterations, repairs, improvements or
additions to the Premises or to the building of which they are a part as
Landlord may deem necessary or desirable. Landlord may at any time place on or
about the Premises any ordinary "For Sale" signs and Landlord may at any time
during the last ninety (90) days of the term hereof, place on or about the
Premises any ordinary  "For Sale or Lease" signs, all without rebate of rent or
liability to Tenant.

                13.14 Auctions. Tenant shall not place any auction sign upon the
Premises or conduct any auction thereon without Landlord's prior written
consent.

                  13.15 Liens. Tenant shall keep the leased Premises and the
property in which the leased Premises are situated free from any liens arising
out of any work performed, materials furnished or obligations incurred by
Tenant. In the event Tenant becomes insolvent, voluntarily or involuntarily
bankrupt, or if a receiver, assignee or other liquidating officer is appointed
for the business of the Tenant, then the Landlord may cancel this Lease at
Landlord's option.

                  13.16 Signs. All signs or symbols placed in the windows or
doors of the Premises, or upon any exterior part of the building, by the Tenant
shall be subject to the approval of the Landlord or Landlord's agents. In the
event Tenant shall place signs or symbols on the exterior of said building, or
in the windows or doors where they are visible from the street, that are not
satisfactory to the Landlord or Landlord's agents, the Landlord or Landlord's
agents may immediately demand the removal of such signs or symbols, and the
refusal of the Tenant to comply with such demand within a period of twenty-four
(24) hours will constitute a breach of this Lease, and entitle the Landlord to
immediately recover possession of said Premises in the manner provided by law.
Any signs so placed on the Premises shall be so placed upon the understanding
and agreement that Tenant will remove same at the termination of the tenancy
herein created and repair any damage or injury to the Premises caused thereby,
and if not so removed by Tenant then Landlord may have same so removed at
Tenant's expense.

                  13.17 Governmental Fees. All the fees due the city, county or
state on account of any inspection made on said Premises by any officer thereof
shall be paid by Tenant.

                  13.18 Removal of Property. In the event of any entry in, or
taking possession of, the Premises as aforesaid, the Landlord shall have the
right, but not the obligation, to remove from the Premises all personal property
located therein, and may place the same in storage at a public warehouse at the
expense and risk of the owners thereof.

                  13.19 Attorney's Fees. If either party brings an action to
enforce the terms hereof or declare rights hereunder, the prevailing party in
any such action, on trial or appeal, shall be entitled to its reasonable
attorney's fees to be paid by the losing party as fixed by the court.

         14. FIRE AND OTHER CASUALTY. In the event the Premises are destroyed or
damaged by fire, earthquake, or other casualty to such an extent as to render
the same untenantable in whole or in substantial part thereof, it shall be
optional with the Landlord to rebuild or repair the same and after the happening


<PAGE>   12


of any such contingency, the Tenant shall give the Landlord or Landlord's agents
immediate notice thereof. Landlord shall have not more than sixty (60) days
after date of such notifcation to notify the Tenant in writing of Landlord's
intentions to rebuild or repair said Premises, or the part so damaged as
aforesaid, and if Landlord elects to rebuild or repair said Premises, Landlord
shall prosecute the work of such rebuilding or repairing without unnecessary
delay, and during such period the rent of said Premises shall be abated in the
same ratio that that portion of the Premises rendered for the time being unfit
for occupancy shall bear to the whole of the leased Premises. If the Landlord
shall fail to give the notice aforesaid, Tenant shall have the right to declare
this Lease terminated by written notice served upon the Landlord or Landlord's
agents.

                In the event the building in which the Premises hereby leased or
located, shall be destroyed or damaged by fire, earthquake or other casualty
(even though the Premises hereby leased shall not be damaged thereby) to such an
extent that in the opinion of Landlord it shall not be practicable to rebuild or
repair, then it shall be optional with Lessor or Tenant terminate this Lease by
written notice served on either party within sixty (60) days after such
destruction or damage.

                15. NOTICES. Whenever under this Lease provision is made for any
demand, notice or declaration of any kind, or where it is deemed desirable or
necessary by either party to give to serve any such notice, demand or
declaration to the other party, it shall be in writing and served either
personally or sent by United State mail, postage prepaid, addressed at the

hereof, and further warrants that Tenant, upon paying the basic rent and all
additional rent and other charges, and performing all the other terms of this

by or through the Landlord, subject, however, to the reservations and conditions

written addendum to this Lease.

1.5 Possession. Possession of the Premises shall be given to Tenant upon signing

and effect as of the date of possession and Tenant shall be subject to all of
the terms, conditions, provisions and obligations of the Lease except that
Tenant's obligation to pay base rent and additional rent shall not commence
until the date that the Initial Term commences unless so stated elsewhere within
this Lease.

                                ARTICLE II. Term

the word "Term" shall mean the Initial Term and any applicable Option Term.

2.2 Initial Term. The Initial Term of this Lease shall be for Three Years
commencing on August 1, 1994 and terminating on July 31, 1997.

2.3 Option Term. Tenant is given the option to extend the term on all the

Successive 3 year term "Option Term" following the expiration of the Initial
Term by giving written notice of the exercise of each option to Landlord at
least six months before the expiration of the preceding term. Provided however,
these options may only be exercised if this Lease has not been previously
terminated, by failure to exercise a prior option or otherwise, and Tenant is
not in default of its obligations hereunder at the time the option notice is
received by the Landlord.

                               ARTICLE III. Rent

3.1 Definitions. The following definitions shall apply to this
Lease:

        (a) Base Rent: base rent is defined as the fixed annual rent set
forth herein, as adjusted from time-to-time, payable by Tenant to Landlord.

        (b) Additional Rent: additional rent is defined as all additional
amounts payable by Tenant to Landlord pursuant to the terms of this Lease
including but not limited to the items described in section 3.5 below.

        (c) Lease Year: a Lease Year is defined as the twelve month
period beginning on August 1 and ending on July 31.

                                       2
<PAGE>   9


this Lease, and any applicable Option Term, an annual Base Rent with cost of
living increases determined as follows:

                (a) For the Initial Term the Base Rent shall be as set forth
in the Addendum to Lease Agreement as attached hereto.

                (b) For the first Lease Year of each Option Term the Base Rent
shall be the greater of (i) the then annual Fair Market rent for the Premises as
agreed between Landlord and Tenant in accordance with ARTICLE 3.9 below, or (ii)
an amount equal to the Base Rent for the preceding Lease Year plus any cost of
living increase computed in accordance with the formula set forth below.

                (c) For each subsequent Lease Year of an Option Term the Base
Rent shall be an amount equal to the Base Rent for the preceding Lease Year plus
any cost of living increases computed in accordance with the formula set forth
below.

3.3 Cost of Living Formula. All cost of living increases to the Base Rent shall
be computed in accordance with the following formula, except that the annual
cost of living increase shall not exceed 8% for any one Lease Year:

                (a) The consumer price index "Northeast Urban Consumers-All
Items" published by the United States Department of Labor, Bureau of Labor
Statistics ("Index") which is published for the fifth full calendar month
preceding the Lease Year for which the increase is being computed ("Extension
Index") shall be compared with the Index published for the same calendar month
of the preceding calendar year ("Beginning Index").

                (b) If the Extension Index has increased over the Beginning
Index, the Base Rent shall be adjusted by multiplying the Base Rent by a
fraction the numerator of which is the Extension Index and the denominator of
which is the Beginning Index;

                (c) By way of example assume on November 1, of the current
calendar year the Lease enters its third Lease Year. Assume also that the Base
Rent for the second Lease Year was 10,500. The Extension Index would be the
Index published for the preceding month of June (the fifth calendar month
preceding the Lease Year for which the increase is being computed). Assume that
Index to be 1.60. The Beginning Index would be that Index published for the
month of June twelve months earlier (the preceding calendar year). Assume that
Index to be 1.50. The Base Rent for the preceding Lease Year or the second Lease
Year would then be multiplied by the fraction 1.60/1.50. The resulting product
of $ 11,200 would be the Base Rent for the third Lease Year.

                If the Index is changed so that the base year of the Index
differs from that used as of the commencement of this Lease, the Index shall be
converted in accordance with the conversion factor published by the United
States Department of Labor, Bureau of Labor Statistics. If the Index is
discontinued or revised while this Lease is in effect, such other government
index or computation with which it is replaced shall be used in order to obtain
substantially the same result as would be obtained if the Index had not been
discontinued or revised.

coverage, scope or amount of any such policy.

        (c) Provide that it WILL not be invalidated as to Landlord as an
additional insured by reason of any act or omission by Tenant or if Tenant has
made any misrepresentation in its application for insurance.

        This Lease is and shall be prior to any encumbrance recorded after the
date of this Lease. If, however, a lender requires that this Lease be

<PAGE>   19


destroyed from a risk covered by the Landlord's insurance rendering the Premises
totally or partially inaccessible or unusable, Landlord shall, with reasonable
dispatch, restore the Premises to substantially the same condition as they were
in immediately before destruction and such destruction shall not terminate this
Lease. Provided, however, in the event there is a total destruction or a partial
destruction which exceeds forty percent (40%) of the gross floor area of the
Premises, either Landlord or Tenant may elect to terminate this Lease by giving
notice thereof to the other party within thirty (30) days of the destruction.
Provided further, Landlord shall have thirty (30) days from the date of the
destruction to notify Tenant as to the length of time the restoration shall
take. If the restoration can be completed within one hundred and twenty (120)
days from the date of destruction, the Landlord shall proceed with the

hundred and twenty (120) days. If the restoration cannot be completed within one
hundred and twenty (120) days from the date of destruction, Tenant shall have
ten (10) days from the date of Landlord's notification to elect to terminate
this Lease failing which this Lease shall remain in full force and effect and
Landlord will proceed expeditiously with the restoration and complete the same
with reasonable dispatch. In any event, if the existing laws do not permit the
restoration, either party can terminate this Lease immediately by giving notice
to the other party.

        16.2 Destruction Due to Risk Not Covered by Insurance. If, during the
term, the Premises, are totally or partially destroyed from a risk not covered
by Landlord's insurance required by this Lease, for reasons other than
Landlord's failure to maintain said insurance, rendering the Premises totally or
partially inaccessible or unusable, Landlord shall restore the Premises and
other improvements in which the Premises are located to substantially the same
condition as they were in immediately before destruction, and such destruction
shall not terminate this Lease. Provided, however, Landlord shall have thirty
(30) days from the date of the destruction to notify Tenant as to the length of
time the restoration shall take. If the restoration can be completed within one
hundred and twenty (120) days from the date of destruction, the Landlord shall
proceed with the restoration with reasonable dispatch and shall complete the
same within the one hundred and twenty (120) days. If the restoration cannot be
completed within one hundred and twenty (120) days from the date of destruction,
Tenant shall have ten (10) days from the date of Landlord's notification to
elect to terminate this Lease failing which this Lease shall remain in full
force and effect and Landlord will proceed expeditiously with the restoration
and complete the same with reasonable dispatch. Provided, further, if the cost
of restoration exceeds ten percent (10%) of the then replacement value of the
Premises or of the Building, Landlord can elect to terminate this Lease by
giving notice to Tenant within thirty (30) days after determining the
restoration cost and replacement value. If the existing laws do not permit
restoration, either party can terminate this Lease immediately by giving notice
to the other party.

        In the ease of destruction to the Premises only, if Landlord elects to
terminate this Lease Tenant, within fifteen (15) days after receiving Landlord's
notice to terminate, can elect to pay to Landlord, at the time Tenant notifies
Landlord of its election, the difference between ten percent (10%) of the then
replacement value of the Premises and the actual

                                       13


<PAGE>   20


cost of restoration, in which case Landlord shall restore the Premises. Landlord
shall give Tenant satisfactory evidence that all sums contributed by Tenant as
provided in this Paragraph have been expended by Landlord in paying the cost of
restoration.

        If Landlord elects to terminate this Lease and Tenant does not elect to
perform the restoration or contribute towards the cost of restoration as
provided in this Paragraph, this Lease shall terminate.

        In any event if the existing laws do not permit restoration, either
party can terminate this Lease immediately by giving notice to the other party.

        16.3 Extent of Landlord's Obligation to Restore. If Landlord is required
or elects to restore the Premises, Landlord Shall not be required to restore
alterations made by Tenant, Tenant's improvements, Tenant's trade fixtures, and
Tenant's personal property, such excluded items being the sole responsibility of

        17.2 Total Taking. If the Premises are totally taken by condemnation,
this Lease shall terminate as of the date of taking.

        17.3 Partial Taking. If any portion of the Building is taken by
condemnation, this Lease shall remain in effect, except that either party can
elect to terminate this Lease if twenty-five percent (25%) or more of the total
number of square feet in the Premises is taken and the remaining portion of the
Premises is rendered unsuitable for Tenant's continued use of the Premises,
provided, however, Landlord can elect to terminate this Lease if twenty-five
percent (25%) or more of the total number of square feet in the Building is
taken. Landlord shall notify Tenant immediately upon receipt of formal notice by
any condemnor of its intent to condemn by taking any portion of the Building or
the property upon which it is situated.

its right to terminate pursuant to this ARTICLE by giving notice to the other
party within thirty (30) days after the nature and extent of the taking have

<PAGE>   21


terminate this Lease as provided in this ARTICLE, the date of termination shall
be thirty (30) days after such party notifies the other party of its election to
terminate or on the date of taking, whichever occurs later. If neither party
elects to terminate this Lease as provided herein, this Lease shall continue in
full force and effect, except that rent shall be reduced pursuant to this
ARTICLE.

        17.4 Effect on Rent. If any portion of the Premises is taken by
condemnation and this Lease remains in full force and effect, on the date of
taking the Base Rent shall be reduced by an amount that bears the same ratio to
the Base Rent as the total number of square feet in the Premises taken bears to
the total number of square feet in the Premises immediately before the date of
taking. All items of Additional Rent based on square footage shall be increased
or decreased depending upon the extent of the taking of the Premises and of the
Building.

        17.5 Restoration of Premises. If there is a partial taking of the
Premises and this Lease remains in full force and effect, Landlord shall restore
the Premises to as good condition as they were in immediately prior to the
taking less the amount of area taken. Landlord, however, shall not be required
to restore alterations made by the Tenant, Tenant's improvements, Tenant's trade
fixtures, or Tenant's Personal property except to the extent that any such items
may be included in the award made to Landlord as a result of the condemnation.

        17.6 Award-Distribution. All condemnation proceeds shall belong to and
be paid to Landlord, except that Tenant may petition the condemner for an award
attributable to Tenant's improvements or alterations made to the Premises by
Tenant in accordance with this Lease, which improvements and restorations Tenant

Lease, and a sum for loss of good will.

        17.7 Temporary Taking. The taking of the Premises or any part of the

one hundred eighty (180) day period, all of the provisions of this Lease shall
be in full force and effect, except that rent shall be abated or reduced during
such period of taking based on the extent to which the taking interferes with
Tenant's use of the Premises, and Landlord shall be entitled to whatever award

manner transfer this Lease or any interest therein, nor sublet all or any part
of the Premises, nor license concessions nor lease departments therein, without
Landlord's prior written consent, which consent shall not be unreasonably
refused or delayed. Consent by Landlord to any assignment or subletting shall
not waive the necessity for consent to any subsequent assignment or subletting.
This prohibition shall include a prohibition against any involuntary subletting
or assignment by operation of law. Tenant understands that the use of the
Premises for research and development and offices is governed by the
requirements of Landlord's approvals from the Lebanon Zoning Board of Adjustment
and

                                       15


<PAGE>   22


that the failure of a proposed use by a subtenant to be permitted as research
and development or office shall be reasonable grounds for Landlord to withhold
consent to such a subtenancy.

        18.2    Omitted

A waiver by Landlord of any of the requirements of this ARTICLE with respect to
a particular prospective assignee or sublessee shall not constitute a waiver of
the requirements with respect to any other prospective assignee or sublessee.

        18.3 Corporate Ownership. If at any time while this Lease is in effect
Tenant shall choose to incorporate, it is expressly understood and affirmed that
said corporation shall assume all of Tenant's obligations under this Lease
Agreement and that a written agreement so stating shall be executed by Tenant
and Landlord.

        18.4 Involuntary Assignment. No interest of Tenant in this Lease shall
be assignable involuntarily by operation of law (including, without limitation
the transfer by testacy or intestacy). Each of the following acts shall be
considered an involuntary assignment: (i) if Tenant, or if Tenant is a
partnership or consists of more than one person or entity, if any partner of the
partnership or other person or entity, is or becomes insolvent, makes an
assignment for the benefit of creditors, or becomes a party to a proceeding
under the Bankruptcy Act in which the Tenant, partner or other person or entity
is the debtor; (ii) if a writ of attachment, execution or other levy is levied
on this Lease; or (iii) if, in any action or proceeding to which Tenant is a
party, a receiver is appointed with authority to take possession of the
Premises.

        An involuntary assignment shall constitute a default by Tenant and
Landlord shall have the right to elect to terminate this Lease, in which case
this Lease shall not be treated as an asset of Tenant. If a writ of attachment,
execution or other levy is levied on this Lease, provided, however Tenant shall
have the right to cure this default as set forth in ARTICLE 19.1 (c). If any
involuntary proceeding in bankruptcy is brought against Tenant, or if a receiver
is appointed, Tenant shall have sixty (60) days in which to have the involuntary
proceeding dismissed or the receiver removed.

                              ARTICLE XIX. Default

        19.1    Tenant's Default. The occurrence of any of the following shall
constitute a default by Tenant:

        (a) Failure to pay Base Rent or Additional Rent within five (5) days of
written notice from Landlord of the non-payment of rent on the due date.

        (b) Abandonment of or vacating the Premises.

        (c) A breach of or the failure to perform any other provision of this
Lease, whether it be a condition or a covenant, if the breach or the failure to
perform is not cured within thirty (30) days after notice has been given to
Tenant. If the default cannot reasonably be cured within

                                       16


<PAGE>   23


thirty (30) days, Tenant shall not be in default of this Lease, if Tenant
commences to cure the default within the thirty (30) day period and diligently
and in good faith continues to cure the default until such default is cured.
Notices given under this paragraph shall specify the alleged default and the
applicable Lease provisions, and shall demand that Tenant perform the provisions
of this Lease within the applicable period of time, or quit the Premises. No
such notice shall be deemed a forfeiture or a termination of this Lease unless
Landlord so elects in the notice.

        19.2 Remedies. Landlord shall have the following remedies if Tenant
commits a default. These remedies are not exclusive; they are cumulative in
addition to any remedies now or later allowed by law.

        (a) Landlord can continue this Lease in full force and effect, and the
Lease will continue in effect as long as Landlord does not terminate Tenant's
right to possession, and Landlord shall have the right to collect rent when due.
During the period Tenant is in default, Landlord can enter the Premises and
relet them, or any part of them, to third parties for Tenant's account. Tenant
shall be liable immediately to Landlord for all costs Landlord incurs in
reletting the Premises, including, without limitation, brokers' commissions,
reasonable attorney's fees, expenses of remodeling the Premises required by the
reletting, and like costs. Reletting can be for a period shorter or longer than
the remaining term of this Lease, for a greater or lesser space with an
appropriate apportionment of rent to those relet portions of the Premises, and
may include good faith reasonable rent concessions. Tenant shall pay to Landlord
the net rent due under this Lease on tho dates such rent is due, less the rent
Landlord receives from any reletting. No act by Landlord allowed by this
paragraph including but not limited to the acceptance of the keys to the
premises, repossession through any lawful means, the making of alterations to
the Premises, or the entering into a reletting agreement upon learning of
Tenant's intent to vacate but before actual vacation, shall terminate this Lease
unless Landlord notifies Tenant that Landlord elects to terminate this Lease.

        (b) Landlord can terminate Tenant's right to possession of the Premises
at any time. No act by Landlord, including but not limited to those authorized
by the preceding paragraph or the appointment of a receiver on Landlord's
initiative to protect Landlord's interest under this Lease, other than giving
written notice to Tenant shall terminate this Lease. On termination, Landlord
has the immediate right to recover from Tenant:

        (i) The worth, at the time of the award, of the unpaid net rent
applicable to the period of time up to the termination;

        (ii) Any other amount, including court cost and reasonable attorney's
fees, necessary to compensate Landlord for all detriment proximately caused by
Tenant's default.

        "The worth, at the time of the award," as used in (i) of this section,
includes any late charges and interest charges permitted in ARTICLE 3.7.

        If the Demised Premises or any part thereof be relet by Landlord for the
unexpired term of this Lease, or any part thereof, before


                                       17
<PAGE>   24


presentation of evidence on the fair and reasonable rental value, to any court
or other hearings officer, the amount of rent reserved upon such reletting shall
prima facie be the fair and reasonable rental value for the part or whole of the
Premises so relet during the term of the reletting period.

        (c) Unless Landlord elects to terminate this Lease and pursue recovery
pursuant to the preceding paragraph (b), no termination of this Lease, by any
voluntary or involuntary act or omission of Landlord or Tenant or by operation
of the law, shall relieve Tenant of its obligations under this Lease, including
but not limited to its obligations to pay rent and additional rent, for the
remainder of the term. All such obligations shall expressly survive termination.

        19.3 Right to Cure Defaults. Landlord may, but shall not be obligated
to, at any time and without notice to Tenant, cure any default by Tenant under
this Lease. Whenever Landlord so elects, all costs and expenses incurred by
Landlord in curing such default, including, without limitation, reasonable
attorneys' fees, together with interest on the amount of such costs and expenses
shall be paid by Tenant to Landlord on demand and shall be recoverable as
Additional Rent.

        Tenant may, but shall not be obligated to, at any time and without
notice to Landlord, cure any default by Landlord under this Lease. Whenever
Tenant so elects, all costs and expenses incurred by Tenant in curing such
default, including, without limitation, reasonable attorney's fees, together
with interest on the amount of such costs and expenses shall be paid by Landlord
to Tenant on demand and may be recoverable as abated Additional Rent.

                     ARTICLE XX. Landlord's Right to Enter

        Landlord, or its authorized representatives shall have the right to
enter the Premises at all reasonable times upon reasonable notice (except in the
case of an emergency) to Tenant for any of the following purposes:

        (a) To determine whether the Premises are in good condition and whether
Tenant is complying with its obligations under this Lease;

        (b) To do any necessary maintenance and to make any restoration to the
Premises;

        (c) To post any notices required or allowed under the provisions of
this Lease;

        (d) To post "for sale" signs or "for rent" signs during the last six (6)
months of the Initial Term or any Option Term or during any period while Tenant
is in default;

        (e) To show the Premises to prospective brokers or buyers or to
prospective tenants of the Premises during the last six (6) months of the
Initial Term or any Option Term or during any period while Tenant is in default;

                                       18


<PAGE>   25


        (f) To shore the foundations, footing and walls of the Premises and to
erect scaffolding and protective barricades around and about the Premises, but
not so as to prevent entry to the Premises and to do any other act or thing
necessary for the safety, preservation or expansion of the Premises or the
Building.

        Landlord shall not be liable in any manner for any inconvenience,
disturbance, loss of business, nuisance or other damage arising out of
Landlord's entry on the Premises as provided in this ARTICLE, except damage
resulting from negligent acts or omissions of Landlord or its authorized
representative.

        Tenant shall not be entitled to an abatement or reduction of rent if
Landlord exercises any right reserved in this ARTICLE.

        Landlord shall conduct its activities on the Premises as allowed in this
ARTICLE in a manner that will cause the least possible inconvenience, annoyance
or disturbance to Tenant.

        It is expressly understood and agreed that Tenant will have and store
upon the Premises certain proprietary information and products and Tenant shall
have the right to require Landlord or Landlord's authorized representatives to
sign Tenant's Non-Disclosure form, a copy of which shall be attached to this
Lease Agreement as Exhibit D.

                              ARTICLE XXI. Waiver

        No delay or omission in the exercise of any right or remedy of Landlord
on any default by Tenant shall impair such a right or remedy or be construed as
a waiver.

        The receipt and acceptance by Landlord of delinquent rent shall not
constitute a waiver of any other default; it shall constitute only a waiver of
timely payment for the particular rent payment involved.

        No act or conduct of Landlord, including, without limitation, the
acceptance of the keys to the Premises, shall constitute an acceptance of the
surrender of the Premises and accomplish a termination of the Lease unless so
stated by Landlord in writing.

        Landlord's consent to or approval of any act by Tenant requiring
Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent to or approval of any subsequent act by Tenant.

        Any waiver by Landlord of any default must be in writing and shall not
be a waiver of any other default concerning the same or any other provision of
the Lease.

                 ARTICLE XXII. Sale or Transfer of the Premises

        If Landlord sells or transfers the Premises, Landlord on consummation of
the sale or transfer, shall be released from any liability thereafter accruing
under this Lease if Landlord's successor has assumed in writing, for the benefit
of Tenant, Landlord's obligations under this Lease.

                                       19


<PAGE>   26


        If any security deposit or prepaid rent has been paid by Tenant,
Landlord can transfer the security deposit or prepaid rent to Landlord's
successor or return said security deposit to Tenant and on such transfer
Landlord shall be discharged from any further liability in reference to the
security deposit or prepaid rent.

                     ARTICLE XXIII. Surrender: Holding Over

        23.1 Surrender. On the expiration or within ten days after any other
termination of the term, Tenant shall surrender to Landlord the Premises and all
Tenant's improvements and alterations in good condition (except for ordinary
wear and tear occurring after the last necessary maintenance made by Tenant and
destruction to the Premises covered by Article XVI), except for alterations that
Tenant has the right to remove or is obligated to remove under the provisions of
Article IX. Tenant shall remove all of its personal property within the
above-stated time. Tenant shall perform all restoration made necessary by the
removal of any alterations or Tenant's personal property within the time period
stated in this Article.

        Landlord can elect to retain or dispose of in any manner any alterations
or Tenant's personal property that Tenant does not remove from the Premises on
expiration or termination of the term as allowed or required by this Lease by
giving at least three days notice to Tenant. Title to all such alterations or
Tenant's personal property that Landlord elects to retain or dispose of on
expiration of the three day period shall vest in Landlord. Tenant waives all
claims against Landlord for any damage to Landlord resulting from Landlord's
retention or disposition of any such alterations or Tenant's personal property.
Tenant shall be liable to Landlord for Landlord's cost for storing, removing,
and disposing of any alterations or Tenant's personal property.

        If Tenant fails to surrender the Premises to Landlord on expiration or
within ten days after termination of the term as required by this Article,
Tenant shall hold Landlord harmless from all damages resulting from Tenant's
failure to surrender the Premises, including without limitation, claims made by
a succeeding Tenant resulting from Tenant's failure to surrender the Premises.

        23.2 Holding Over. If Tenant shall hold over after the expiration of the
term hereby created, it shall be deemed a renewal of this Lease and of all the
terms, covenants and conditions herein contained, which shall continue from
month-to-month, except that the monthly Base Rent shall be double the last
month's Base Rent hereunder, and either Landlord or Tenant may terminate such
holding upon thirty (30) days' written notice.

                       ARTICLE XXIV. Estoppel Certificate

        Tenant agrees from time-to-time, upon not less than fifteen (15) days
prior written request by Landlord, to execute, acknowledge and deliver to
Landlord a statement in writing, which conforms substantially to Exhibit B
attached hereto, certifying that this Lease is unmodified and in full force and
effect and that Tenant has no defenses, offsets or counterclaims against its
obligations to pay rent and additional charges and to perform its other
covenants under this Lease and that there are no uncured defaults of Landlord or
Tenant under this Lease (or, if there have

                                       20


<PAGE>   27


been any modifications and, if there are any defenses, offsets, counterclaims,
or defaults, setting them forth in reasonable detail), and the dates to which
the Base Rent and Additional Rents have been paid. Any such statement delivered
pursuant to this ARTICLE may be relied upon by a prospective purchaser or
mortgagee of the leased Premises. Failure to deliver the certificate within the
15 days shall be conclusive upon the Tenant for the benefit of the Landlord that
this Lease is in full force and effect and has not been modified except as may
be represented by the Landlord and that Landlord is not in default of any of its
obligations hereunder.

        Tenant shall have the same right to request an Estoppel Certificate from
Landlord under the same conditions as outlined in Paragraph One of this ARTICLE
XXIV.

                         ARTICLE XXV. Signs and Awnings

        No signs or awnings shall be placed on the Premises without the
Landlord's written consent which shall not be unreasonably withheld. No signs
other than directory signs and signs advertising Tenant's business shall be
placed on the Premises. All signs and awnings must conform to the Lebanon Zoning
Ordinance, be aesthetically pleasing and in good taste. No signs or awnings
shall be fastened to the Building except in an architecturally sound manner so
as not to injure or deface the Building, and Tenant shall be solely responsible
for the repair of all damage resulting therefrom.

                            ARTICLE XXVI. Recording

Upon signing, the parties shall execute a Notice of Lease in recordable form.

                             ARTICLE XXVII. Notice

        Any notice or demand required by this Lease shall be in writing and
shall be delivered or served in any commercially reasonable manner. The burden
of proving delivery or service shall be on the party issuing the notice or
making the demand. In any event delivery or service shall be deemed made when
made by certified mail, return receipt requested, addressed to the respective
party at the mailing address first set forth above or at such other address as
may be designated by either party from time to time in writing.

        modifications thereof in any sum.

                2. Notwithstanding the provisions of Section 1 of this

        in the performance of any of the terms, covenants, or conditions of the
        Lease on Tenant's part to be performed, Tenant's possession and

        Year Two (8/1/95-7/31/96)        Actual Operating Cost for 
                                         both Area # 1 and Area # 2
                                         Capped at $ 3.25/sf**

be totally responsible for the payment of utilities which service the Premises.
Capped Additional Rent costs apply to all other costs of operation.

        d) Both parties agree that Tenant requires specialized fit-up for the
operation of Tenant's business beyond the "plain vanilla" fit-up provided by
Landlord. The parties further agree and affirm that Tenant shall pay to
Landlord, as additional rent, the costs of the specialized fit-up amortized over
the Lease Term and more fully explained in the Second Addendum to Lease
Agreement attached hereto. Repayment of fit-up expenses shall be in equal
monthly installments over the Lease Term excepting in the event Tenant shall
exercise its Right to Terminate the Lease Agreement as cited in Section (e)
below. In the event Tenant shall exercise its Right to Terminate, Tenant shall
pay to Landlord any and all payments due for fit-up repayment prior to the
termination of the Lease.

        e) Both parties agree that the Lease Agreement and this First Addendum
to Lease Agreement shall be contingent upon approval from the responsible
governing Boards of the City of Lebanon, New Hampshire.

        f) Landlord shall grant to Tenant the right to terminate the Lease
Agreement and this First Addendum to Lease Agreement on 7/31/96 by providing
Landlord with written notification of Tenant's intent to terminate the Lease no
later than January 31, 1996.

        g) Both Landlord and Tenant agree that Tenant has expressed its interest
in expanding the Premises to space adjacent to the Leasehold when and if
Tenant's business operations require additional space. Landlord agrees that
prior to entering into a lease agreement with another Tenant for said adjacent
space, Landlord will inform Tenant of its intent to lease the space, for how
long the lease term would be and to provide Tenant with the opportunity to
discuss the space with Landlord and to negotiate with Landlord terms and
conditions for leasing said adjacent space. It is expressly understood by both
parties that Landlord is in no way granting to Tenant any right to the adjacent
space.

        h) Landlord agrees that Landlord will at his sole expense apply for any
and all necessary permits required for the operation of Tenant's business as
office and research and development including the obtaining of a Certificate of
Occupancy. It is expressly understood that Landlord shall not be liable for any
other permitting beyond that required for Tenant's initial occupancy of the
leasehold.

        i) The above cited Lease Agreement notwithstanding, rent shall commence
at occupancy by Tenant or August 1, 1994 whichever shall occur first. In the
event necessary permits, including the Certificate of Occupancy shall not have
been issued, rent shall commence at the time of said issuance.

expressly intended to apply after the termination hereof, including without
limitation, those contained in Section 5, except as otherwise set forth herein.

equal to eighty-five thousand dollars ($85,000).

            4.2 Salary Bonus. After the Employee has been employed by the
Company for twelve (12) months, Employee will participate in the Company's

Employee and the Board of Directors of the Company.

            4.3 Stock Bonus. In addition to the annual base salary set for the
above, the Company shall provide to Employee a stock bonus of thirty thousand
(30,000) shares of the Company's voting common stock, $.01 par value, to be

connected in any manner with any business engaged in or related to teaching,
training or certification through the use of interactive medical simulation or
the sale or development of computed aided surgical systems or components
thereof. Employee will be deemed to be connected with a business if such
business is carried on by a partnership in which he is a general or limited
partner, consultant or employee, or a corporation or association of which he is
a shareholder, officer, director, employee, member, consultant or agent;
provided, however, that nothing herein shall prevent the purchase or ownership
by Employee of shares of less than 1% of the outstanding shares in a publicly
held company.

            5.2 Nonsolicitation. Commencing as of the date of this Agreement and
continuing three (3) years after termination of Employee's employment with the

of this Agreement and thereafter, he will not, except to the Company, its
subsidiaries, and affiliates, communicate or divulge to any person, firm or
corporation, either directly or indirectly, any confidential or proprietary
information relating to and including this Agreement and the business, customers
and suppliers or other affairs of the Company, its parents, subsidiaries and
their affiliates, except as may be deemed necessary in carrying out the normal

breach of this Agreement by the Company.

including, without limitation, Section 5.

                    90 consecutive days due to sickness, disability or any other

            7.3 Compensation Upon Termination. Employee shall be entitled to
compensation earned through the date of termination if termination is with cause
by the Company, without cause by Employee or because of Employee's death or
disability as provided in Section 7.2(a) or (b). If termination is without cause
by the Company, then Employee shall be entitled to the compensation in effect
pursuant to this Agreement at the time of termination through the end of the
term of this Agreement but in no event greater than one (1) year, including all
deferred compensation and applicable bonuses. Employee shall not be entitled to
any compensation upon termination without cause until such Employee has been
employed by the Company for twelve (12) consecutive months. Notwithstanding the
foregoing, Employee and the Company shall each use reasonable efforts to
mitigate any monetary damages suffered by each as a result of the termination of
Employee's employment and that the Company shall be entitled to offset any
amounts earned by the Employee during the one (1) year period after termination
by the Company against any amounts owed to the Employee by the Company as a
result of the Company's termination of the Employee.

            7.4 Enforceability. Despite termination of this Agreement, and
irrespective of whether such termination has been effected with or without cause
by either Company or Employee, such termination shall not affect the continuing

intended to apply after the termination hereof, including without limitation,
those contained in Section 5, except as otherwise set forth herein.

         8. Cause and Breach.

<PAGE>   5
              5.2. No forbearance, indulgence, delay or failure to exercise any
right or remedy with respect to this Note shall operate as a waiver, nor as an
acquiescence in any default, nor shall any single or partial exercise of any
right or remedy preclude any other or further exercise thereof or the exercise
of any other right or remedy.

              5.3. This Note may not be modified or discharged except by a
writing duly executed by the Payor and the Payee.

February 22, 1996

                                Letter Agreement

Dear

         This Letter Agreement is forwarded to you in regards to the number of
shares of Ixion, Inc., a Delaware corporation (the "Company") common stock to be
issued to each bridge investor in connection with each investor's investment.
The Company's common stock to be issued in connection with your bridge
investment will be issued upon completion of the Company's initial public
offering. In this regard, please be advised the Company has entered into a
Letter of Intent with Kaufman Bros., L.P. for a contemplated initial public
offering of a number of shares of the Company equal to forty percent (40%) of
the Company's outstanding common stock on a fully diluted basis.

         The Company's records indicate that you have invested $          
which entitles you to, in addition to the return of this $          at 8% per
annum, that number of shares of the Company's common stock equal to the same
dollar value. As set forth in the Company's Amended Confidential Private
Offering Memorandum, for each twenty five thousand dollar ($25,000) investment,
such investor is entitled to five thousand (5,000) shares of the Company's
common stock at the time of the Company's initial public offering, assuming an
initial public offering price of five dollars ($5.00) per share. Since the
initial public offering price of the Company's common stock has not been
established, however, the Company is not able to issue certificates to any
bridge investors at this time.

         In the event the initial public offering price of the Company's common
stock is five dollars ($5.00) per share, you will receive that number of shares
equal to your investment divided by five dollars ($5.00) (e.g. if you invested
$25,000, you will receive 5,000 shares). If the initial public offering price of
the Company's common stock is greater than five dollars ($5.00) per share, each
investor will be entitled to receive a number of shares less than five thousand
(5,000) (e.g. if you invested $25,000 and the initial public offering price is
$10.00 per share, you will receive 2,500 shares). Conversely, if the initial
public offering price of the Company's common stock is less than five dollars
($5.00) per share, each investor will be entitled to receive a number of shares
greater than five thousand (5,000) (e.g. if you invested $25,000 and the initial
public offering price is $2.50 per share, you Will receive 10,000 shares).
Accordingly, the number of shares ultimately issued to each investor is a
function of the initial offering price of the Company's common stock.

         It is the Company's intent to provide to each investor that number of
shares that equals, on a dollar value, the investor's initial investment,
excluding accrued interest. The Company intends to accomplish this by simply
dividing the investor's initial investment by the initial public offering price.
Until such initial public offering price is finalized,

                                   Ixion, Inc.
         654 Madison Avenue Suite 1606 New York, NY 10021 212/319-3500
         1335 N. Northlake Way Suite 102 Seattle, WA 98103 206/547-8801

however, no certificates representing the number of shares to which each
investor is entitled can be issued.

         Please acknowledge that you understand and accept the terms set forth
above. Your acknowledgement will also confirm that you shall be entitled to that
number of shares of the Company's common stock representing your initial
investment, excluding accrued interest, divided by the initial public offering
price of the Company's common stock.

         If you have any questions or comments with respect to the above, please
do not hesitate to contact me.

                                              Sincerely,


                                              /s/ Bruce D. Sturman
                                              --------------------------------

        After the fifth year, should minimum royalties fall below $200,000 per
year, the exclusive license granted ETHICON herein shall become non-exclusive.

        5.5.1  The royalty payments set forth in Paragraph 5.5 are in lieu of
any effort or responsibility on the part of ETHICON to market or develop
Royalty Bearing Products at any time during the term of this Agreement. After
the first Royalty Year, if ETHICON does not pay the minimum royalties in 5.5,
IXION's sole remedy shall be to convert the exclusive license granted in this
Agreement to a non-exclusive license. In the event that IXION has the right to
convert ETHICON's rights to a non-exclusive license, royalty payments due by
ETHICON to IXION shall be actual earned royalties only. Any such remedy shall
be taken only upon written notice to ETHICON. ETHICON shall have ninety (90)
days upon the receipt of such notice to make up any deficiencies in order to
maintain the exclusive license granted under this Agreement.

        5.5.2  It should be noted that any regulatory delays in the sale of
Royalty Bearing Products shall not be construed as a failure by ETHICON to
market such products as provided herein.

<PAGE>   14
        5.6  Payments by ETHICON under Paragraphs 5.3 through 5.5 shall
continue for as long as there are Royalty Bearing Products made within the
scope of the Technology covered by IXION patents of by pending patent
applications if such applications were filed within five years of the effective
date of this Agreement.

        5.7  Records

        ETHICON shall keep complete and accurate records of the Net Sales of
Royalty Bearing Products with respect to which a royalty is payable according
to this Agreement and within sixty (60) days following each quarterly period of
a Royalty Year, ETHICON shall render to IXION a written report, certified
accurate by an officer of ETHICON, setting forth gross sales, permitted
discounts, net sales, number, description and actual or established list
selling or list lease price of all royalty bearing products under this license
sold, leased, or otherwise disposed of or put into use by ETHICON and its sub
licensees during such report period and the royalties due IXION thereon.
ETHICON shall, upon rendering such report, remit to IXION in U.S. dollars the
amount of royalty shown thereby to be due. On non-U.S. sales, IXION will accept
a Royalty paid 60 days after each Royalty year until ETHICON's standard royalty
reporting becomes quarterly. In lieu of royalty reports as required above,
ETHICON may make its royalty reports on their standard royalty report form as
shown in Appendix E hereof.

        5.8  Audits

        At its expense, IXION shall have the right to nominate an independent
public accountant acceptable to and approved by


                                       13
<PAGE>   15
ETHICON which approval shall not be unreasonably withheld, who shall have access
to ETHICON's records during reasonable business hours for the purpose of
verifying the royalty reports as provided for in this Agreement, but this right
may not be exercised more than once in any Royalty Year, and the accountant
shall disclose to IXION only information relating solely to the accuracy of the
royalty report and the royalty payments made according to this Agreement.
Receipt of acceptance by IXION of any statements furnished pursuant to this
Agreement or of any sums paid hereunder shall not preclude IXION from
questioning the correctness thereof at any time. If any inconsistencies or
mistakes are discovered in any statements of payments, they shall be immediately
rectified and the appropriate payments made by ETHICON. ETHICON shall bear the
expense of any examination or audit conducted by IXION if a deficiency greater
that Fifteen Percent (15%) or more in Royalty Payments is discovered.

         5.9 Sale of Business

         Upon the sale by ETHICON of its endoscopic surgery business, IXION
agrees upon the request of ETHICON, to enter into a separate agreement with the
purchaser of ETHICON's business relating to IXION Patents or the sale of Royalty
Bearing Products. Any such agreements made pursuant to this Paragraph will
contain the terms and conditions relating to licenses granted and royalty
payments contained in this Agreement. Except upon sale by ETHICON of its
endosurgery business, all rights



                                       14
<PAGE>   16
granted hereunder to ETHICON shall be non-transferable without prior written
consent of IXION.



                         ARTICLE VI - PATENT INFRINGEMENT


         6.1.1 Third Party Infringement During the license period, IXION and
ETHICON shall each give prompt notice to the other of any infringement of the
IXION Patents by third parties as may come to their knowledge.

         6.1.2 So long as ETHICON'S License remains exclusive, ETHICON shall
have the right to pursue legal action against infringement of an IXION Patent by
third parties' activities in the Field. Should such legal action require that
IXION be joined as party plaintiff. IXION shall not reasonably withhold
permission to bring such action, and to join IXION as party plaintiff. If
ETHICON pursues such legal action on its own, ETHICON shall bear its own costs,
and retain any profits, settlement or damages awarded as a result of such
action. Any costs to pursue such litigation shall be credited against royalty
payments due IXION up to fifty percent (50%) of payment due in any Royalty Year
Quarter. If ETHICON settles such third party infringement action, and a
settlement agreement or judicial decree includes royalties or payment for lost
sales by ETHICON, IXION shall be entitled to royalty payments on such amounts if
IXION is due a royalty for the years representing such royalties

                                        15
<PAGE>   17
or payment for lost sales, less litigation expenses incurred by ETHICON. Any
recovery of costs or attorneys fees shall be shared by IXION and ETHICON in the
proportion to which they each contributed to the financing of such costs and
attorney's fees, such by IXION's aforementioned reduced royalties.

        6.1.3  IXION, if not in attendance, will be kept informed on the
progress of any suit by ETHICON reports periodically, or monthly upon request
by IXION. IXION may at all times be represented by counsel of its own choosing
and may at any time initiate infringement actions or join in actions initiated
by ETHICON. For such action, IXION shall be responsible for all of its own
costs. IXION also agrees to provide at ETHICON's expense for out of pocket
costs, all reasonable cooperation in the prosecution of such infringement.

Should ETHICON be unable to prosecute such an infringement of an IXION patent
in its own name as provided in this Section 6.1.2. then IXION agrees to the
filing of suit in IXION's name and will within thirty (30) days after request
by ETHICON provide ETHICON with all necessary documents for prosecution of such
infringement in IXION's name. In the event ETHICON is unable, by operation of
law, to bring such an infringement action under any of the IXION patents, IXION
at the request of ETHICON, shall institute such action in its own name through
such attorneys as ETHICON may designate to handle such legal action. ETHICON
shall pay all costs of any such action.

        6.2  Infringement by ETHICON

        6.2.1  If, in exercising their rights under this Agreement, ETHICON or
one of its sub licensees are accused of infringing a patent owned by a third
party, ETHICON may enter into negotiations with such third party to obtain
rights under such third party patent. ETHICON shall periodically inform IXION
of the status of any such infringement action or negotiations. If, in obtaining
such rights, ETHICON or its sub licensee is required to make any payments to
such third party solely by reason of IXION's design as embodied in the
replicable simulator prototype


                           
                                       16
<PAGE>   18
to be delivered hereunder, and not by reason of any changes from said design
incorporated in the Royalty-Bearing Products produced or used by ETHICON or its
sub licensees, or by reason of the use of the accused product by ETHICON or its
sublicensees in a manner not contemplated by the parties hereto at the time of
delivery of the product, the royalties payable to IXION on sales in the country
in which ETHICON has obtained rights from the third party shall be reduced by
the amount of said payments up to fifty percent (50%) of the royalty due to
IXION from such sales in that country.

        6.2.2 If ETHICON is sued for infringing any issued patent contemplated
in Paragraph 6.2.1, and ETHICON elects to defend such a lawsuit, then if such
charge of infringement resulted solely by reason of IXION's design as embodied
in the simulator prototype to be delivered hereunder, and not by reason of any
changes from said design incorporated in the Royalty-Bearing Products produced
or used by ETHICON or its sub licensees, or by reason of the use of the accused
product by ETHICON or its sublicensees in a manner not contemplated by the 
parties hereto at the time of delivery of the product, both IXION and ETHICON
shall equally share in the costs and legal fees incurred in defending such
infringement action. IXION's costs and legal fees shall be deducted from any
royalties due IXION, provided that in any period, IXION shall receive no less
than fifty percent (50%) of any royalties due it. Unless IXION has been joined
as a party defendant, all decisions regarding the settlement of such litigation
or the taking of a license as described in Paragraph 6.2.1 shall be vested
solely with ETHICON. Otherwise the parties agree to consult with each other
regarding any settlement contemplated by them or either of them.


                                       17
<PAGE>   19
         6.2.3 The costs of litigation's referred to in Paragraphs 6.1 and 6.2
shall include but not be limited to such out-of-pocket expenses as court costs
and court fees, reasonable travel expenses, reasonable charges for the
professional services of outside counsel and experts, and shall exclude only the
time that ETHICON's regular employees devote to such litigation.

                                       18
<PAGE>   20
such confidential information as if it were its own and shall not "reverse
engineer" know-how to the other party's detriment. Notwithstanding the
foregoing, the receiving party shall be relieved of the confidentiality
obligations herein and shall not be prevented by this Agreement from utilizing
any information received by it from the disclosing party if:

         a.  the information was previously known to the receiving party;

         b.  the information is or becomes generally available to the public
             through no fault of the receiving party, including information
             disclosed as a result of publications and/or laying open for
             inspection by the public of any patent applications that the
             disclosing party may file, or

         c.  the information is acquired in good faith in the future by the
             receiving party from a third party who is not under an obligation
             of confidence to the disclosing party with respect to such
             information.

         7.5 Termination

         ETHICON may terminate this Agreement during the Program or the license
period by giving IXION ninety (90) days advance written notice of its intention
to terminate. Such termination by ETHICON shall cancel any options or licenses
granted to ETHICON by IXION which have not become fully paid-up licenses. Such
termination, however, shall not release ETHICON from its obligations to make any
pro-rated payments or royalties accrued and unpaid up to the effective date of
such termination, nor the provisions of Paragraph 7.2. In the event of
termination of the license by ETHICON during the Program, ETHICON agrees to
return to IXION all prototypes, drawings and other materials belonging to IXION,

         2. ETHICON FUNDING

         A.   For the above deliverables, ETHICON ENDO-SURGERY will pay a fixed
              fee of $2.8 Million (Two Million Eight Hundred Thousand Dollars)
              to IXION, INC. Payment schedules are as follows:

              (i)   Contracts commencement - $1,000,000 (less $200,000 start-up
                    fee paid December 23, 1991). Moneys used for manpower
                    resources, computer hardware/software; consultants,
                    overhead, General Administrative, as in Part 4 of this
                    Appendix.

              (ii)  At the end of the eighth month from the Effective Date or
                    demonstration of Laparoscopic Diagnostic Simulator described
                    in 3.4, whichever is sooner $600,000.

              (iii) At the end of the Progress Review after the twelfth month
                    from the Effective Date - $700,000.

              (iv)  At the end of the eighteenth month from the Effective Date
                    or the receipt of a final Laparoscopic Skills Simulator
                    (whichever is later) - $500,000.

                                       31
<PAGE>   33
                    However, a penalty of $100,000 per month will be deducted
                    for delay of Final Simulator up to a maximum of $300,000, so
                    long as ETHICON ENDO-SURGERY requirements for skills and
                    acquiring human footage have been met.

                    Conversely, a bonus of Three Hundred Thousand Dollars
                    ($300,000) shall be paid if a functional Final Simulator
                    shall be delivered before the end of the fifteenth month, a
                    bonus of Two Hundred Thousand Dollars ($200,000) shall be
                    paid if a functional Final Simulator shall be delivered
                    before the end of the sixteenth month, and a bonus of One
                    Hundred Thousand Dollars ($100,000) shall be paid if a
                    functional Final Simulator shall be delivered before the end
                    of the seventeenth month,

         3. GENERAL

         3.1. There will be a joint progress review every sixty days. H.R.
              Trumbull M.D. will be ETHICON ENDO-SURGERY point person and the
              coordinator of the Project.

         3.2  The prototype two-dimensional video simulator will be designed in
              a manner which can be produced for under $40,000 per unit in lots
              of 50.



                                       32
<PAGE>   34
         3.3  Major variations from, additions to, or subtractions from the
              above deliverables must be covered in timely fashion by a mutually
              acceptable Change Order.

         3.4  As part of the 10 month performance review, IXION will demonstrate
              a Laparoscopic Diagnostic Simulator (human footage) on a prototype
              simulator platform. This will include a simulated camera cannula
              and allow visual inspection of the full hemisphere from the camera
              portal. This demonstration will employ the developmental simulator
              platform, and thus should not be considered a carry-away product
              or exhibit.

              3.4.1 Because this will be part of a design and development stage
              of the simulator program, it is highly possible that this hardware
              and software will not be upwardly compatible to later versions.
              Thus, if an interim system is desired by ETHICON for location at
              their site, ETHICON will provide:

                  A. Funding for two interim systems, one of which will be a
                  spare at IXION. The software and hardware will be "frozen" at
                  the acceptance of the demonstration, and no additional
                  improvements will be requested by ETHICON.



                                       33
<PAGE>   35
                  B. An ETHICON technical correspondent will be assigned, and
                  committed up to full time for maintenance of that hardware and
                  software.

          3.5 The only additional expenses to be paid under the Program by
              ETHICON ENDO-SURGERY shall be expenses for reasonable travel to
              and filming which will be paid for by ETHICON ENDO-SURGERY, based
              on receipts submitted. Ethicon will manage all logistics of such
              activities, including any necessary compliance requirements to
              governmental or regulatory laws.

          3.6 Should acquisition of anatomical images timely to the schedule of
              the simulator be delayed due to no fault of IXION, this will not
              defer any payment milestones mentioned above, and will furthermore
              automatically create an Extension under 2.4 of necessary length to
              the Program and furthermore extend the periods above which define
              both bonuses and penalties above. Furthermore, should these
              acquisition circumstances prevent the milestone payment at eight
              months, that payment will be made at eight months. The first such
              image acquisition should occur during the fourth month of this
              program,

          3.7. All hardware purchased for IXION as in Appendix B, which remains
              intact, shall continue to be the property of ETHICON ENDO-SURGERY.

<PAGE>   39
manner described herein will bind IXION for that period ETHICON wishes to
exercise its Right of First Refusal, or for ninety (90) days, whichever comes
first. Prior to the end of the Right of Refusal Period of ninety (90) days,
IXION must have written notice from ETHICON that ETHICON does not intend to
exercise that Right, before IXION can commit the product or methodology to other
parties, even if those other parties have seen the material in other
disclosures. After ninety (90) days from the period wherein ETHICON from the
period ETHICON receives such material in the manner described above, IXION has
the right to purvey that material in any manner it wishes without official
notification from ETHICON.

         1.4 Should ETHICON wish to exercise this Right of First Refusal, it
thereupon will engage some form of legal agreement with IXION to take action
upon the disclosure by IXION, whether that be an extension Option, Sale, Lease,
or form of joint activity mutually agreed upon.

         1.5 All materials will be held confidential in the manner described
under Article VII of this agreement.

         1.6 No action by either ETHICON or IXION in relation to these Non-Field
and Non-Technology related disclosures will in any way affect the Program or the
License agreed to in the document to which this is Appended or to any of the
other Appendixes attached to that document.

         an Intellectual Property Right against whom a court or other tribunal
         has awarded damages for such infringement to MMS or its Affiliates to
         the extent that MMS receives payment of such damages, and settlement of
         any infringement claim to the extent that MMS has received payment
         therefor. The term Transfers as used herein shall not be construed in a
         manner that entitles MusculoGraphics to more than one royalty payment
         for any unit of Licensed Products. Transfer may be used in this
         Agreement as a noun or as a verb, and in either instance shall be
         interpreted to effectuate the meaning set forth in this Section.

                         ARTICLE 2: PRODUCT DEVELOPMENT

         2.1 In a site to be provided by MusculoGraphics, at MusculoGraphics'
sole expense, MusculoGraphics shall develop, specify in writing and transfer to
MMS the Licensed Products, all relevant know-how reasonably necessary and
appropriate to enable MMS to use the Licensed Products, and documentation for
the structure, operation and use of the Licensed Products. MusculoGraphics shall
complete said development according to the Development Schedule, which is
consistent with MMS milestones.

         2.2 MMS shall pay to MusculoGraphics, as compensation for the
development efforts set forth in Section 2.1, the amount of four hundred
sixty-five thousand dollars ($465,000) for the Consulting Term of this
Agreement. The compensation payable under this Section shall be paid in
installments as follows, provided that the deliveries to be made upon the
milestone dates set forth on the Development Schedule, which correspond to or
precede the installment dates set forth below, have been made:

                  2.2.1    The first installment of $150,000 shall be paid
                           within three days after the execution of this
                           Agreement.

                  2.2.2    The second installment of $150,000 shall be paid on
                           August 1, 1993.

                  2.2.3    The third installment of $165,000 shall be paid on
                           November 2, 1993.

In the event that one or more required deliveries have not been made by the
corresponding or earlier milestone dates set forth on the Development Schedule,
the installments to be made at the time of or following such deliveries will not
be paid until all over-due deliveries have been made.

         2.3 In addition to the compensation set forth in Section 2.2, and not
offsetting any compensation payable thereunder, MMS has paid to MusculoGraphics,
prior to the Effective Date, compensation in the amount of one hundred
ninety-five thousand seven hundred dollars ($195,700) for work performed prior
to the Effective Date.

         2.4 During the Consulting Term, MMS shall pay reasonable travel and
related expenses for MusculoGraphics' officers, directors and/or employees to
travel between MMS and MusculoGraphics for purposes related to this Agreement,
and for other travel requested by MMS specifically requests travel to design
reviews in June and October, 1993, MusculoGraphics shall pay all other travel
expenses of its officers, directors or employees related to this Agreement.

         2.5 MMS shall include the following legend on the first screen display
generated by each System, in such a manner as to be readily visible to users of
a System:

                               ALL RIGHTS RESERVED

and on any printed material or videotape showing an image generated by the
Licensed Products, or a simulation thereof, provided that MMS shall only be
required to include such legend from the Effective Date through a date five (5)
years following the first Transfer of a System.

         2.6 MMS shall have no additional obligation to compensate
MusculoGraphics beyond the amount set forth above except as hereinafter provided
(in Article 4) or as otherwise agreed in writing by the parties.

         2.7 MusculoGraphics agrees to provide a written report within ten (10)
days of the end of each calendar quarter that specifies work done by
MusculoGraphics during that quarter.

                           ARTICLE 3: CONFIDENTIALITY

         3.1 All confidential information, data, research notes and know-how (i)
developed under this Agreement, or (ii) which was developed or obtained outside
this Agreement, transmitted between MMS and MusculoGraphics in connection with
this Agreement, whether in tangible or machine readable form, that is identified
in writing as confidential at the time such information is transmitted by a
party or within ten (10) days thereafter, shall be deemed "Proprietary
Information." Nothing in this Article shall be construed to apply to the
computer software covered by that License Agreement dated December 28, 1992,
between the Parties.

         3.2 Any Proprietary Information provided to MMS by MusculoGraphics, and
any non-Proprietary Information developed by MusculoGraphics or supplied to MMS
by MusculoGraphics, shall be owned exclusively by MusculoGraphics.

         3.3 Any Proprietary Information provided to MusculoGraphics by MMS, and
any non-Proprietary Information developed by MMS or supplied to MusculoGraphics
by MMS, shall be owned exclusively by MMS.

         3.4 Any Proprietary Information developed jointly by MMS and
MusculoGraphics shall be owned jointly by MMS and MusculoGraphics. Such
information shall be deemed to be jointly developed if a patent application
drafted narrowly to claim the information as an invention (if such a patent
application were filed for such information, though no such application actually
need be filed) would require that an officer, director or employee of each of
MMS and MusculoGraphics lawfully be named as inventors thereof.

         3.5 During a term beginning on the Effective Date and running through
the end of the period consisting of (i) the Royalty Period plus (ii) five (5)
years, each of the parties to this Agreement agrees to hold in confidence, and
to refrain from using, distributing, disseminating or disclosing to others, any
Proprietary Information of the other party as defined in this Section, or from
making or causing to be made any product embodying Proprietary Information of
the other party, except in furtherance of this Agreement and permitted thereby;
provided, however, that no party shall be restrained from using Proprietary
Information of the other party if the Proprietary Information at issue:

                  3.5.1    is shown to be information in the public domain
                           rather than through the relationship of the parties,
                           or that becomes a part of the public domain through
                           no fault of the party; or

                  3.5.2    as shown by written records, was lawfully in the
                           possession of the party prior to its disclosure by
                           the other party; or

                  3.5.3    as shown by written records, is hereafter acquired by
                           the party from a third party that is lawfully in
                           possession of such Proprietary Information and under
                           no obligation of confidence to the other party; or

                  3.5.4    as shown by written records is independently
                           developed by an employee or consultant of the party,
                           which employee or consultant has had no exposure to
                           such Proprietary Information, as demonstrated by the
                           party alleging independent development.

Notwithstanding the foregoing, to the extent any Proprietary Information
constitutes a trade secret, each of the parties to this Agreement agrees to hold
such Proprietary Information in confidence, and to refrain from using,
distributing, disseminating or disclosing such Proprietary Information to others
indefinitely, subject to the provisos set forth in Sections 3.5.1 to 3.5.4.

         3.6 Nothing in this Agreement shall prohibit MusculoGraphics, its
officers, directors or employees from presenting or publishing academic papers
relating to the work performed by MusculoGraphics under this Agreement, provided
that such publication:

                  3.6.1    does not reveal any trade secret or other Proprietary
                           Information of MMS or any jointly owned information,
                           as described in Section 3.4 above; and

                  3.6.2.   is submitted to MMS prior to being submitted for
                           publication or presentation, and MMS fails to object
                           to such publication or presentation within sixty (60)
                           days after submission to MMS.

Upon notice and presentation to MMS of a paper which MusculoGraphics intends to
publish, MMS shall have sixty (60) days in which to either (i) file (or take
diligent steps to have filed) applications for Intellectual Property Rights
relating to the subject of the proposed publication or presentation; (ii) advise
MusculoGraphics that it does not intend to file an application for Intellectual
Property Rights relating to the subject of the proposed publication but has an
objection to such publication or presentation; or (iii) advise MusculoGraphics
that it has no objection to the proposed publication. The failure of MMS to
provide such notice shall be interpreted as a waiver of any objection to such
presentation or publication. Any objection hereunder shall point specifically to
the subject matter as to which MMS objects to the publication or presentation.

                          ARTICLE 4: EXCLUSIVE LICENSE

         4.1 For the period beginning with the Consulting Term and extending
through the end of the Royalty Period of this Agreement, MusculoGraphics hereby
grants to MMS and its Affiliates the sole and exclusive worldwide right to
develop, make (and have made), prepare copies of, Transfer and otherwise use
Systems or practice any invention or the art claimed under or as any
Intellectual] Property Rights or Proprietary Information of MusculoGraphics
(collectively, "MMS' Right") in the field of medical arthroscopy, namely, the
use of an arthroscope to perform surgical procedures relating to the
musculoskeletal system of the human body, including training and pre-procedure
modeling, as well as actual surgical procedures. MusculoGraphics further grants
to MMS and its Affiliates the right to sublicense MMS' Right, or any part
thereof. Following the expiration of the Royalty Period, MMS shall receive a
fully paid-up, perpetual license for the Licensed Products in MMS' Field of Use.

         4.2 Ownership

                  4.2.1    All inventions or other intellectual property
                           developed solely by MMS, in connection with work
                           performed under this Agreement by MusculoGraphics,
                           shall be exclusively owned by MMS, and
                           MusculoGraphics shall have no rights to such
                           inventions or intellectual property. MusculoGraphics
                           shall retain all right, title and interest to
                           inventions and other intellectual property that it
                           solely develops under this Agreement, and MMS shall
                           have no rights to such inventions or intellectual
                           property, other than as set forth in Section 4.1 and
                           in Section 3.4.

                  4.2.2    MusculoGraphics shall promptly notify MMS in writing
                           of any inventions MusculoGraphics has developed under
                           this Agreement. Except as otherwise set forth in this
                           Agreement, MMS shall be financially responsible for,
                           and have sole control over, the filing and
                           prosecution of applications for Approvals for the
                           Licensed Products or

                           Systems, Intellectual Property Rights, and the
                           enforcement and maintenance of all such Intellectual
                           Property Rights throughout the world.

                  4.2.3    MusculoGraphics shall have the right to file, at its
                           own expense and in its own discretion, applications
                           for Intellectual Property Rights relating to the
                           Licensed Products that MusculoGraphics has solely
                           developed, as to which MMS has declined to file an
                           application for an Intellectual Property Right, or in
                           such countries or regions as MMS had declined to file
                           an application for an Intellectual Property Right.
                           MMS shall provide MusculoGraphics with sufficient
                           notice (of not less than forty-five (45) days before
                           the right to file such an application expires,
                           provided that MusculoGraphics has notified MMS at
                           least ninety (90) days before the right to file such
                           an application expires), to MusculoGraphics to obtain
                           Intellectual Property Rights. MMS shall notify
                           MusculoGraphics of the first proposed offer to
                           Transfer or public display of Systems not less than
                           one hundred-twenty (120) days prior to that first
                           proposed offer or public display.

                  4.2.4    The parties shall cooperate with one another in the
                           prosecution and enforcement of Intellectual Property
                           Rights, at the sole expense of the party filing an
                           application for such an Intellectual Property Right
                           or having the right to bring or defend the action.

         4.3 Royalties

                  4.3.1    In consideration of the licenses granted hereby and
                           the other covenants of MusculoGraphics made herein,
                           MMS agrees to pay to MusculoGraphics royalties at a
                           percentage rate of the monetary value for which
                           Transfers of Systems are made by MMS, its Affiliates
                           or its sublicensees during the term of the Agreement,
                           the royalty percentage as shall be determined in
                           accordance with Sections 4.3.2 and 4.3.3 of this
                           Section 4.3, and shall be paid on payments that have
                           been received by MMS for such Transfers, in
                           accordance with Section 4.4.

                  4.3.2    Within 120 days (but not later than 90 days) prior to
                           the date on which MMS, its Affiliates or sublicensees
                           proposes to commence the Transfer of a System,
                           MusculoGraphics and MMS shall enter into good faith
                           negotiations in an effort to agree on the royalty
                           rate applicable in Section 4.3.1. Notwithstanding any
                           other provision of this Agreement to the contrary,
                           MusculoGraphics and MMS agree that the royalty
                           percentage shall be (a) no greater percentage than
                           that which, when applied to Net Transfers will
                           provide the Transferring entity (MMS, its Affiliates
                           or sublicensees) the same or a reasonably similar
                           margin as




                                       8
<PAGE>   10
                           would result from the Transfer of products in the
                           industry which are the same or similar to the System
                           Transferred, appropriately reduced to reflect the
                           benefit of research and development funding provided
                           by MMS, and (b) no lower percentage than that which
                           will reflect the proportionate value to the user of
                           the Licensed Products to the entire SEE System.

                  4.3.3    If MusculoGraphics and MMS are unable to agree upon
                           the royalty rate of Section 4.3.1 within 60 days
                           after commencement of discussions pursuant to Section
                           4.3.2 hereof, each of the parties shall deliver to
                           the other, within 5 days thereof, written notice
                           setting forth its statement of the applicable royalty
                           rate (each such stated royalty rate being a "Party's
                           Estimated Royalty Rate"). If the higher of the
                           Party's Estimated Royalty Rate is not more than 110%
                           of the lower Party's Estimated Royalty Rate, then the
                           final applicable royalty rate shall equal the average
                           of the two Party's Estimated Royalty Rate. Otherwise,
                           the parties will agree upon and designate an
                           individual experienced in valuing licenses of
                           technology similar to the License granted hereby (the
                           "Independent Party") to determine the applicable
                           royalty rate in accordance with the provisions of
                           this Section 4.3. Prior to the 30th day after the
                           engagement thereof, the Independent Party shall
                           determine the applicable royalty rate (the
                           "Independent Royalty Rate") and shall deliver written
                           notice thereof to each of MusculoGraphics and MMS.
                           The determination of the Independent Party shall be 
                           final and binding upon MusculoGraphics and MMS, 
                           provided, however, that the final applicable royalty
                           rate may not be less than the lower, nor greater 
                           than the higher, Party's Estimated Royalty Rate. 
                           Each party shall bear one-half the cost of retaining
                           the services of the Independent Party, along with 
                           its own costs, if any, associated with the rendering
                           of those services by the Independent Party.

         4.4 MMS agrees to furnish to MusculoGraphics, within 60 days after the
close of each calendar quarter during the Royalty Period for which payment was
received by MMS for a Transfer, a royalty statement showing Net Transfers of all
Licensed Products for each such quarter. This royalty statement shall also show
total royalties due for such quarter and shall be accompanied by a payment of
such royalties, net of any taxes required to be paid or withheld by Licensee
under applicable law; provided, however, that if any required government
approval for the making of such royalty payment has not been obtained by the end
of such 60-day period, the royalty payment shall be made as soon thereafter as
such approval is obtained. All taxes payable on account of the royalties
provided for herein (including income taxes) shall be borne and paid by
MusculoGraphics for its own account. If MMS is required by law to withhold any
such taxes from royalty payments, MMS shall withhold and pay over to the
appropriate taxing authority the amount of such taxes.

         4.5 Royalties payable pursuant to the provisions of this section shall
be payable to MusculoGraphics at its principal place of business in U.S.
dollars. Any currency conversion shall be made using the exchange rate published
in The Wall Street Journal (Midwest edition) on the last day of the calendar
quarter to which such royalties relate.

         4.6 During the Royalty Period, MMS shall maintain at its principal
office books and records adequate to permit all royalties payable to
MusculoGraphics at any time under the Agreement to be computed and verified.
Such books and records shall be open to inspection and copying during normal
business hours by representatives of MusculoGraphics (who shall be independent
certified public accountants) for the purpose of verifying the accuracy of
royalties paid by MMS under this Agreement.

         4.7 MMS shall pay MusculoGraphics annual minimum royalties according to

                  4.7.2    In the second through fourth calendar years after the
                           year in which Systems have first been Transferred,
                           the amount of minimum royalties shall be one hundred

Consulting Term, unless either party, Sixty (60) days before the end of a term,
notifies the other in writing of its intention not to renew this Agreement.

         5.2 The work to be performed during any Renewal Term, the schedule for
performing such work, and the amount of compensation to be received therefor,

shall expire on the last day of the Consulting Term as a result of nonrenewal.

         5.3 The expiration of the consulting provisions of the Agreement as a
result of nonrenewal shall not affect the rights or obligations of the parties
under Articles 3, 4, 6, 7, 8, 9, and 10. The rights and obligations of the
parties shall not be affected in any way by the expiration of the consulting
provisions of this Agreement.

         5.4 The expiration of the consulting provisions of this Agreement as a
result of nonrenewal by MMS shall trigger a payment by MMS to MusculoGraphics of
two hundred thousand dollars ($200,000) payable in the following installments:

                  5.4.1    An installment of one hundred thousand dollars

                           date of expiration of the consulting provisions of
                           this Agreement.

                  5.4.3    An installment of twenty-five thousand dollars

                           of the first installment.

In no event shall MMS be obligated to make payments under this Section 5.4 if

models or musculoskeletal modeling systems are being developed for the SEE
System by MMS, or by a third party at the request of MMS, its Affiliates or
sublicensees.

                             ARTICLE 6: TERMINATION

         6.1 If, within five (5) years from the actual date of delivery of the

licenses granted by MusculoGraphics to MMS with regard to the Licensed Products,
the Intellectual Property Rights, Proprietary Information of MusculoGraphics and
any work performed by MusculoGraphics hereunder shall revert exclusively to
MusculoGraphics. However, the right to use any jointly owned Proprietary
Information as defined in Section 3.4 shall be retained




                                       11

by MMS and MusculoGraphics following termination, provided that such use does
not violate the exclusive rights of either party.

         6.2 In the event that either MMS or MusculoGraphics is in material
breach of this Agreement, and the same has not been cured within sixty (60) days
following written notice by the other party of the nature of the breach, the
non-breaching party may terminate this Agreement. If any uncured breach within
the meaning of this Section occurs through acts or omissions of MMS, Section 6.1
shall govern the disposition of all proprietary rights hereunder; if any uncured
breach within the meaning of this Section occurs as a result of MusculoGraphics'
acts, MMS shall have a royalty-free license, as set forth in Section 4.1, to the
Licensed Products.

         6.3 Bankruptcy

                  6.3.1    If a petition in bankruptcy or for reorganization is
                           filed by or against MMS, or if any insolvency
                           proceedings are instituted by or against MMS under
                           any state or federal law, or if it makes an
                           assignment for the benefit of its creditors, or if a
                           receiver is appointed for its property and business
                           and remains undischarged for a period of sixty (60)
                           days, or if any execution or attachment is levied on
                           any of its assets and remains undischarged for a
                           period of sixty (60) days, MusculoGraphics shall have
                           the right, if it so elects, to terminate this
                           Agreement as provided in Section 6.2 hereof.

                  6.3.2    If a petition in bankruptcy or for reorganization is
                           filed by or against MusculoGraphics, or if any
                           insolvency proceedings are instituted by or against
                           MusculoGraphics under any state or federal law, or if
                           it makes an assignment for the benefit of its
                           creditors, or if a receiver is appointed for its
                           property and business and remains undischarged for a
                           period of sixty (60) days, or if any execution or
                           attachment is levied on any of its assets and remains
                           undischarged for a period of sixty (60) days (any of
                           the foregoing being referred to hereafter as a
                           "Bankruptcy Event"), on the day prior to such
                           Bankruptcy Event, MusculoGraphics shall be deemed to
                           have transferred its interests in the Intellectual
                           Property Rights and Proprietary Information to MMS in
                           consideration of the payment of royalties hereunder,
                           which amount shall be paid in the same manner and at
                           the same time as the Royalties would have been paid
                           hereunder; provided, however, that if MusculoGraphics
                           is in bankruptcy directly as a result of wrongful
                           non-payment by MMS of monies due hereunder by MMS,
                           no transfer under this Section shall occur or shall
                           be deemed to have occurred. If such Bankruptcy Event
                           occurs during the Consulting Term, such Transfer will
                           be deemed to have been made in consideration of
                           amounts already paid by MMS to




                                       12
<PAGE>   14
                           MusculoGraphics, and any amounts then due to be paid
                           by MMS to MusculoGraphics for services already
                           rendered by MusculoGraphics.

         6.4 In the event of termination under any of the above Sections 6.2 or
6.3, MusculoGraphics shall be paid for all work that has been performed prior to
termination, and for any royalties that have accrued but are not paid as of the
date of termination.

         6.5 The obligations of Articles 3, 7, 8 and 9 shall not be suspended or
discharged as a result of termination of this Agreement.

                              ARTICLE 7: INSURANCE

         7.1 MMS agrees to provide adequate product liability insurance for
liabilities that may be reasonably foreseen in relation to the operation of

additional insureds for all claims and liabilities relating to or arising from
the Licensed Products (or any System) wherever distributed by MMS, its
Affiliates or sublicensees, including, but not limited to personal injury and
property damages. The amount and conditions of such insurance or indemnity shall
be the same as that which MMS provides for itself for the Transfer of the
Licensed Products. MMS shall provide MusculoGraphics with certificates of

shall result from any change in insurer or coverage. The obligations of this
Section shall not be terminated or expire by operation of Articles 5 or 6 of

         8.2. MusculoGraphics shall indemnify and hold MMS, and each of its
partners, harmless from any damage, liability, cost, claim or suit incident to
the representation set forth above. MMS shall provide prompt notice of any such

         10.10 Reformation/Severability

                  10.10.1  If any provision of this Agreement is declared
                           invalid or unenforceable by any tribunal, then such
                           provision shall be deemed automatically adjusted to
                           the minimum extent necessary to conform to the
                           requirements for validity as declared at such time
                           and, as so adjusted, shall be deemed a provision of
                           this Agreement as though originally included herein.
                           In the event that the provision so declared is of
                           such a nature that it cannot be so adjusted, the
                           provision shall be deemed deleted from this Agreement
                           as though such provision had never been included
                           herein. In either case, the remaining provisions of
                           this Agreement shall remain in effect.

                  10.10.2  Notwithstanding Section 10.10.1, in the event that
                           any portion of Articles 2, 3, 4 or 7 is declared
                           invalid or unenforceable by any tribunal, this
                           Agreement shall be terminated in accord with Section
                           6.2.

         10.11 Force Majeure. No party shall be liable for any failure or delay
in performing its obligations hereunder due to any external cause beyond its
reasonable control, including without limitation, fire, accident, acts of the
public enemy, war, rebellion, labor dispute or unrest, insurrection, sabotage,
transportation delays, shortage of raw materials, energy or machinery, acts of
God, government or the judiciary, or other matters beyond the reasonable control
of a party.

         10.12 Successors and Assigns. Neither this Agreement nor any of the
rights or obligations hereunder shall be assignable by any party hereto without
the written consent of the other party first obtained and any attempted
assignment without such written consent shall be void and confer no rights upon
any third party; provided, however, that MMS may assign any of its rights under
this Agreement to Baxter or any of its affiliates. Subject to the foregoing,
this Agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective representatives, heirs, successors and
permitted assigns.

         10.13 Time of the Essence. The parties agree that time is of the
essence in this Agreement, provided, however, each party shall have a reasonable
time to cure any breach of this Agreement as provided by Section 6.2, hereof.

<PAGE>   4



         confidential nature. When such information is exchanged and/or
         developed, it will be appropriately identified in writing by the party
         asserting the proprietary or confidential nature. The receiving party
         agrees to protect such information for a period of five (5) years from
         the date of receipt or a period of three (3) years from completion or
         termination of this Agreement, whichever is longer, and to use such
         information only in the performance of the Project.

         party will be returned at the conclusion of the Contract Period.

Article 6 - Publications

6.1      MMS recognizes that, exclusive of the restrictions in Article 5.2
         above, under DARTMOUTH policy the results of DARTMOUTH's participation
         in this Project must be publishable and agrees that personnel engaged
         in Project shall be permitted to present at symposia, national, or
         regional professional meetings, and to publish in journals, thesis or
         dissertations, or otherwise of their own choosing, methods and results
         of Project, provided, however, that MMS shall have been furnished
         copies of any proposed publication or presentation at least thirty (30)
         days in advance of the submission of such proposed publication or
         presentation to a journal, editor, or other third party. MMS shall have
         thirty (30) days after receipt of said copies to comment upon and/or
         object to such proposed presentation or proposed publication because
         there is subject matter which needs protection. In the event that MMS
         makes such objection, said personnel shall refrain from making such
         publication or presentation for a maximum of thirty (30) days from date
         of receipt of such objection in order, if appropriate, to enable MMS to
         file patent application(s) with the United States Patent and Trademark
         Office and/or foreign patent office(s) directed to the patentable
         subject matter contained in the proposed publication or presentation.
         However, if MMS' objection is that publication would disclose
         confidential information protected under Article 5.2 above, said
         personnel shall refrain from making any publication, presentation, or
         other disclosure until such confidential information is removed.

                                                                          3 of 7

Article 7 - Inventions and Intellectual Property

7.1      Dartmouth acknowledges that the technology which is to be tested by
         Dartmouth's employees during the performance of the Project was
         developed by MMS employees or consultants prior to this agreement, and
         that the technology constitutes intellectual property, confidential and
         proprietary information, and/or trade secrets of MMS. MMS has the right
         to file patent applications of the technology without reference to
         Dartmouth and Dartmouth obtains no rights to the technology by virtue
         of the testing funded under this agreement, except as provided below.

7.2      MMS retains the right to file patent applications on any improvements
         to the technology which may be conceived, developed or reduced to
         practice during the term of this agreement. Inventorship for any such
         improvement to the technology shall be determined by U.S. Patent Law.
         All inventions, discoveries, or improvements arising from the Project,
         conceived solely by Dartmouth's employees, shall be assigned to
         Dartmouth, and all inventions, discoveries, or improvements conceived
         solely by the MMS employees shall be assigned to MMS. For inventions,
         discoveries, or improvements that are conceived jointly by Dartmouth's
         and MMS employees, Dartmouth and MMS will hold joint title. If MMS
         decides that it will not support patent filing costs for Dartmouth
         patent rights or joint patent rights, Dartmouth then can proceed with
         patent filings on its own and at its own expense.

7.3      Mere reduction to practice, testing, or proof of concept by Dartmouth
         employees, without conception, shall not create any ownership rights
         for Dartmouth.

7.4      Dartmouth grants MMS an exclusive option to negotiate an exclusive
         license to Dartmouth patent rights or its portion of any joint patent
         application which may be filed as a result of the testing performed
         under this Agreement. Dartmouth, to the extent it is able to do so
         under its policies and obligations, if any, to third parties, hereby
         grants MMS a one hundred eighty (180 day period), (after the disclosure
         of invention, discovery, or improvement has been made) to exercise the
         option to negotiate the terms of a worldwide exclusive commercial
         license. Such a license shall include a reasonable royalty based on the
         respective parties' contributions and relevant industry standards and,
         subject to Dartmouth's policies, shall include such other terms as are
         typical in licenses of similar technology from non-profit organizations
         to for-profit organizations. If there is no agreement on license terms
         during the ninety (90) day period after the option

                                                                          4 of 7


<PAGE>   6



         exercise, Dartmouth shall be free to offer commercial license rights to
         third parties.

7.5      All provisions of this Article 7 are the subject of Dartmouth - MMS
         Research Agreement Section 2.03.

Article 8 - Term and Termination

8.1      This Agreement shall become effective upon the date first herein above
         written and shall continue in effect for the full duration of the
         Contract Period unless sooner terminated in accordance with the
         provisions of this Article. The parties hereto may, however, extend the
         term of the Agreement for additional period as desired under mutually
         agreeable terms and conditions which the parties reduce to writing and
         sign. Either party may terminate this Agreement upon ninety (90) days
         prior written notice to the other.

8.2      Subject to Article 6, termination of this Agreement by either party for
         any reason shall not affect the rights and obligations of the parties
         accrued prior to the effective date of termination of the Agreement.

Article 9 - Independent Contractor

9.1      In the performance of all services hereunder:

         9.11     DARTMOUTH shall be deemed to be and shall be an independent
                  Contractor and, as such, DARTMOUTH shall not be entitled to
                  any benefits applicable to employees of MMS.

         9.12     Neither party is authorized or empowered to act as agent for
                  the other for any purpose and shall not on behalf of the other
                  enter into any contract, warranty, or representation as to any
                  matter. Neither shall be bound by the acts or conduct of the
                  other.

Article 10 - Indemnity

10.1     MMS shall defend and indemnify and hold DARTMOUTH and its employees
         harmless for any judgments and other liabilities based upon claims or
         causes of action against DARTMOUTH or its employees which arise out of
         (i) the design, production, manufacture, sale, use in commerce, lease
         or

                                                                          5 of 7

         out pursuant to this Agreement, provided that DARTMOUTH promptly
         notifies MMS of any such claim coming to its attention and that it
         cooperates with MMS in the defense of such claim. If any such claims or
         causes of action are made, DARTMOUTH shall be defended by counsel to
         MMS, subject to DARTMOUTH's approval, which shall not unreasonably be
         withheld.

                  MEDICAL MEDIA SYSTEMS FUNDING PROPOSAL TO THE
                STATE OF NEW HAMPSHIRE INDUSTRIAL RESEARCH CENTER

         Medical Media Systems (MMS) is now starting its third year. During our
first two years (07/01/92 - 06/30/94), we have completed our first round of
funding and have developed proof of concept prototypes of several new and
innovative products in medicine. Based on this successful meeting of milestones,
we have been given a second round of funding by our corporate partner, Baxter
Healthcare. We plan to use the second round of funding to bring our products
into clinical trials. MMS continues to be based in the Upper Valley. We would
like to request a second round of funding from the State of New Hampshire
Industrial Research Center. This would be used to develop additional clinical
products that our present funding does not include.

Progress to Date:

         We have completed our incubation period within the Thayer School of
Engineering at Dartmouth College and will be moving this month to West Lebanon.
We have hired a CEO, who is moving here from Illinois, to run our company. We
have successfully negotiated our next round of funding from Baxter. We presently
have eight people working for Medical Media Systems, with plans to hire more in
1995.

         Medical Media Systems has developed a Smart Endoscopic Environment for
knee arthroscopic procedures. We demonstrated the proof of concept system on
11/29/93. This system would be used by the surgeon as a guide for performing
complex reconstructions within the knee such as anterior cruciate ligament
repairs. We are now moving forward to develop a clinical system for FDA trials.
On 04/14/94, we demonstrated a proof of concept system for liver surgery that
would allow the surgeon to remove multiple metastatic tumors and avoid critical
blood vessels. We are now developing this system for clinical trials.

         Our business concept is based on producing patient specific software
for the specific clinical procedure to be performed. We would sell a software
model of the patient's specific anatomy and pathology, whether knee, liver or
other applications to be developed, that would be used by the surgeon as a
navigational map during a specific procedure.

         With over 75 million surgical procedures performed annually on a
world-wide basis, we are excited about the opportunity MMS has to develop
computer-aided surgery products to be used in some percentage of these cases.
These products will ultimately help reduce the cost of the procedure and improve
the outcome.

Outlook for the next year:

         We have divided our development work into three areas: (1) Workstations
to be used by MMS to produce patient specific software: (2) Compuscopes -
endoscopes with computers to perform surgery using our knee and liver patient
specific software: and (3) Preview System that would allow the surgeon to view
and combine 3-D specific radiology data on an inexpensive personal computer.
This Preview System would be used for surgical planning, instruction to the
patient and family, and intra-operatively as a more intuitive surgical map. We
expect to have a Preview System prototype available in 1994 and a product
available for sale in 1995.

Financial Support:

         Baxter Healthcare has provided MMS 5.1 million dollars in support and
has committed to another 2.2 million dollars for next year. These funds would be
used to take our present prototypes into clinical trials. We would like to
request another $50,000 of State of New Hampshire support to develop several new
application areas for our products. These would include ENT sinus surgery and
carpal tunnel release in hand surgery. Both these procedures have very large
markets and would potentially provide an accelerated growth to Medical Media
Systems with introductions of products in these areas in the future.

                           GENERAL RELEASE AGREEMENT

         This General Release Agreement, effective as of May 28, 1996 (the
"Agreement"), is made by and among the Kriegsman Group, a sole proprietorship
owned by Steven Kriegsman ("Kriegsman"), Steven Kriegsman ("Owner"), Medical
Media Systems, Inc., a Delaware corporation ("MMS"), and Ixion, Inc., a Delaware
corporation ("Ixion"), with respect to the following facts:

         A. Ixion previously entered into an agreement with Kriegsman dated June
5, 1995, pursuant to which Kriegsman was to provide certain services to Ixion
(the "Engagement").

         B. Ixion and MMS are contemplating a merger (the "Merger") and a
question has arisen between the parties as to the amount to which Kriegsman is
owed for services rendered to Ixion and/or MMS in connection with the Merger and
certain other transactions.

         C. Ixion, MMS, Kriegsman and Owner have each independently determined
that it is in each party's best interests to settle all outstanding claims as to
Kriegsman's compensation.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, the parties agree as follows:

         1. Consideration to Kriegsman. In full, complete, and final settlement
of all of Ixion's and MMS' obligations to Kriegsman, Ixion agrees to pay 
Kriegsman an aggregate sum of $132,000 cash upon the execution of this 
Agreement (the "Consideration").

         2. Further Acts. Each of the parties shall execute promptly such
further documents and perform such further acts as may be necessary or
appropriate in order to fully carry out and effectuate the purposes of this
Agreement.

         3. General Release. In consideration of the Consideration, and for
other good and valuable consideration, the receipt and sufficiency of which is
acknowledged, Kriegsman and Owner, jointly and severally, on behalf of
themselves, and all of their respective past, present and future agents,
servants, officers, directors, employees, shareholders, principals,
predecessors, alter egos, partners, parent corporations, subsidiaries,
attorneys, insurers, reinsurers, sureties, heirs, executors, administrators,
trustees, successors and assignees, unconditionally release and forever
discharge both MMS and Ixion, individually and collectively, and each of their
respective past, present and future agents, servants, officers, directors,
employees, shareholders, principals, predecessors, alter egos, parent
corporations, subsidiaries, attorneys, insurers, reinsurers,


<PAGE>   3


sureties, administrators, trustees, successors and assignees (collectively, the
"Ixion/MMS Affiliates"), with respect to any and all claims, liabilities and
causes of action, of every nature and description, which have existed in the
past or which now exist, including, but not limited to, any and all claims,
liabilities, and causes of action arising out of or relating to the Engagement,
the Merger or any engagement of Kriegsman or Owner by Ixion, MMS or any
Ixion/MMS Affiliate. Kriegsman and Owner further agree that any and all
agreements and arrangements with Ixion or MMS will be unconditionally terminated
without further consideration upon payment of the Consideration.

         4. Unknown Claims. Kriegsman and Owner each understand that Section
1542 of the California Civil Code provides as follows:

         A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
         KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
         RELEASE, WHICH, IF KNOWN BY HIM, MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR.

         Having been advised with respect thereto, each of Kriegsman and Owner
nevertheless assume all risks for claims arising on their behalf, before or
after the date of this Agreement, now known or unknown, based on facts which
exist on or before the date hereof, or events which occur or have occurred on or
prior to the date hereof, and, notwithstanding the provisions of Section 1542 of
the California Civil Code, or any analogous state law or federal law or
regulation (collectively, the "Release Provisions"), Kriegsman and Owner each
expressly waive their rights pursuant to the Release Provisions and expressly
release Ixion and MMS from all liability for all claims arising out of the 
matter stated above (with the exception of Kriegsman's and Owner's rights to 
enforce the terms of this Agreement).

         Kriegsman and Owner fully understand that if the facts with respect to
which this Agreement is executed are found subsequently to be other than or
different from the facts now believed by Kriegsman and Owner to be true,
Kriegsman and Owner each expressly accept and assume the risk of such possible
difference in fact and agree that this Agreement shall remain effective
notwithstanding any difference of fact.

         5. Confidentiality. Kriegsman and Owner each agree that the terms and
conditions of this Agreement are strictly confidential and shall not be
disclosed to any person by Kriegsman, Owner or any agent or principal of
Kriegsman or Owner, except as required by law.

         6. Covenant Not to Sue. Kriegsman and Owner each covenant not to sue or
otherwise institute or cause to be instituted or in any way participate in legal
or administrative proceedings against Ixion or MMS, or any of their respective
past, present




                                      -2-
<PAGE>   4




and future Ixion/MMS Affiliates, with respect to any and all claims, liabilities
and causes of action, of every nature and description, which have existed in the
past or which now exist, whether or not now known or ascertained, including, but
not limited to, any and all claims, liabilities, and causes of action arising
out of or relating to the Engagement, the Merger or any engagement of Kriegsman
or Owner by Ixion, MMS or any Ixion/MMS Affiliate.

         7. No Admission. The parties agree that this Agreement, and performance
of the acts required by it, does not constitute an admission of liability,
culpability, negligence or wrongdoing on the part of anyone, and shall not be
construed for any purpose as an admission of liability, culpability, negligence
or wrongdoing by any party and/or by any party's present or former parents,
subsidiaries, related entities, predecessors, successors, officers, directors,
shareholders, agents, employees and assigns.

         8. Attorneys' Fees. Should any party hereto employ an attorney for the
purpose of enforcing or construing this Agreement in any legal proceeding
whatsoever, the prevailing party shall be entitled to receive from the other
party or parties thereto reimbursement for all attorneys' fees and all costs
incurred in connection therewith.

         9. Complete Defense. This Agreement may be pleaded as a full and
complete defense to, and may be used as the basis for an injunction against, any
new process, action, suit, claim, administrative action, or other proceeding
which Kriegsman or Owner may initiate, prosecute, or attempt in violation of or
in order to set aside the term hereof.

         10. Governing Law. This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of California, without
giving effect to its conflicts of laws principles.

         11. Successors and Assigns. All the terms of this Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective legal representatives, successors and assigns.

         12. Authority. The parties each represent and guarantee that it has
read and understands this Agreement; has actual authority and power to enter
into and perform this Agreement.

         13. Kriegsman and Owner Representations. Kriegsman and Owner hereby
each represent to Ixion and MMS that Kriegsman is a sole proprietorship and that
neither Kriegsman nor Owner have assigned any right to any cause of action
against either Ixion, MMS or any of the Ixion/MMS Affiliates, that no other
entity or person has any such right and that Kriegsman and Owner shall
indemnify, defend and hold Ixion, MMS and each Ixion/MMS Affiliate harmless from
any claim, liability, expense or




                                      -3-
<PAGE>   5




damage arising out of any breaches of these representations.

         14. Entire Agreement. This Agreement contains the entire agreement
between the parties relating to the transactions contemplated hereby, and all
prior or contemporaneous agreements, understandings, representations, and
statements, oral or written, are merged herein. Kriegsman and Owner expressly
warrant that they have each read and fully understand this Agreement and that
they have each had the opportunity to consult with legal counsel of their own
choosing; that each of Kriegsman and Owner are not executing this Agreement in
reliance on any promises, representations, or inducements other than those
contained herein; and that each of Kriegsman and Owner are executing this
Agreement voluntarily, free of any duress or coercion.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.

<PAGE>   2
               SETTLEMENT AGREEMENT AND RELEASE OF ALL CLAIMS

        The undersigned parties to this Settlement Agreement and Release
("Agreement") represent and agree as follows:

        1.  There is now pending in the United States District Court for the
Western District of Washington, a case entitled Ixion, Inc. v. Cyndel & Co.,
Inc., et al, and related counterclaim, Case No. C94-1485Z (the "Action").
Ixion, Inc. ("Ixion") is the plaintiff and counter-defendant in the Action, and
Cyndel and Co., Inc., Steven J. Bayern, and Patrick Kolenik (collectively, the
"Cyndel Parties") are the defendants and counter-claimants.

        2.  The purpose of this Agreement is to compromise and resolve all of
the disputes and controversies presently existing among the parties to this
Agreement arising out of, or in any way related to, any of the events or
circumstances giving rise to the claims, counterclaims, and defenses raised in
the Action. This Agreement does not apply to, and is not intended to apply to,
any other matters, including but not limited to matters relating to Hydration
Technology, Inc.

        3.  In consideration for the mutual releases described elsewhere in
this Agreement, Ixion shall issue warrants that will give Cyndel the right to
acquire 25,000 shares of Ixion common stock at a price of 150 percent of the
initial public offering price, and 25,000 shares of Ixion common stock at a
price of 160 percent of the initial public offering price. These warrants must
be exercised by the earlier of (i) three years from the date of the initial
public offering, or (ii) March 1, 2001. Both

                                                         [INITIALS ILLEGIBLE]
                                                       ------------------------
                                                                Initials
<PAGE>   3
warrants shall contain piggyback registration rights enabling the holder or
Cyndel to register or join in the registration of the underlying securities,
(i.e., the common stock) in the event Ixion looks to register its common stock,
or common stock held by any shareholder, after the initial public offering. In
addition to these warrants, Cyndel shall receive an option to acquire 20,000
shares of Ixion's common stock at a purchase price of $7.50 per share. This
option must be exercised within 18 months after April 1, 1996, and expires on
November 1, 1997, if not exercised by that date. The option cannot be
exercised, in part, and can only be exercised, in full, where all 20,000 shares
are purchased, at $7.50 per share, at one time, in a single transaction. Cyndel
cannot assign its warrants or options to anyone except Steven J. Bayern or his
immediate family, Patrick Kolenik or his immediate family, or to James J. Ragen
or his law firm Ragen & Cromwell. If Cyndel so assigns any warrants or options,
they cannot thereafter be re-assigned to anyone else. Cyndel, and its
assignees, agree to accept any lockup conditions and time periods imposed by
the underwriter(s), although Ixion will not insist upon or otherwise encourage
the underwriter(s) to require such warrants to be locked up.

        4.  In exchange for the consideration set forth above, all parties
agree that:
                a)  They will dismiss, with prejudice, and in its entirety, the
complaint and counterclaim in the Action, within three business days of the
date of execution of this Agreement; and

                                       2
<PAGE>   4
                b)  They release each other, and all of their respective agents,
employees, employers, attorneys, insurers, directors, officers, members,
partners, shareholders, representatives, successors, assigns, heirs, executors,
administrators, and estates, absolutely and forever, from any and all claims,
demands, obligations, damages, liabilities, actions, or causes of action of any
kind or nature whatsoever, whether based on contract, tort, statute or other
legal or equitable theories of recovery, whether known or unknown, which as of
the date of this Agreement they had or now have, or claim to have, which relate
to Ixion, including all of the matters alleged in the complaint and
counterclaim in the Action.

                c)  Ixion will release any claims or potential claims that it
has, or may have, against Henry Hackel, R.F. Lafferty & Co., and Harold
Horowitz (the "Third Party Settlors"), if all of the Third Party Settlors
execute the mutual release attached hereto as Exhibit "A". If any of the Third
Party Settlors refuse, for any reason, to execute the mutual release in the
exact form attached hereto, within three (3) days after this Agreement is
executed, then this paragraph of the Agreement shall be deemed to be null and
void, and the Agreement, without this paragraph, shall constitute the full,
final, and complete settlement between Ixion and the Cyndel Parties.

        5.  This release does not apply to, and is not intended to apply to, 
claims of any type or kind made by any third parties against Ixion, or against
any of the Cyndel Parties with respect to Ixion. None of the hereto parties has
any obligation under

this Agreement to indemnify any of the other parties for claims brought by any
third party against Ixion, or against any of the Cyndel Parties.

        6.  All parties to this Agreement agree not to encourage, assist,
instigate, or otherwise participate in the prosecution of any claim, lawsuit,
or other type of action or proceeding against any of the other parties except
to the extent they are compelled by judicial process to do so.

        7.  Each party denies any liability to the other party hereto in
connection with the matters which are the subject of this Agreement but desires
to resolve the potential claims and causes of action between and among them.
This Agreement is a compromise of disputed claims; accordingly, this Agreement,
and the furnishing of consideration for this Agreement, shall not constitute an
admission of liability or wrongdoing, any and all of which liability or
wrongdoing is expressly denied.

        8.  This document sets forth the entire agreement between the parties
with respect to the specific subject matter thereof, and supersedes any and all
prior agreements and understandings between the parties pertaining to its
subject matter. The parties agree and acknowledge that there are no
contemporaneous oral agreements between the parties relating to the subject
matter of this Agreement. This Agreement may be amended, or any right or
condition hereunder waived, only by written instrument signed by the party
against whom such an amendment or waiver is sought to be enforced.

        9.  Each party warrants and covenants that it has not

previously assigned, transferred, or suffered a loss of any of the rights which
are at issue in this Agreement, and that this Agreement will constitute a
complete settlement and release according to its terms. Each of the parties to
this Agreement represents and warrants that he has full power and authority to
enter into this Agreement to resolve all the claims and causes of action made

                            ASSET PURCHASE AGREEMENT

        THIS ASSET PURCHASE AGREEMENT (the "Agreement") is made and entered
into this 22nd day of April, 1996, by and between David C. Hon (the "Seller")
having an office at 1335 North Northlake Way, #102, Seattle, WA 98103, and 
Ixion, Inc. a Delaware corporation (the "Buyer" or "Ixion"), having an office 
at 400 West Mercer Street, Seattle, WA 98109.

                                   WITNESSETH

       WHEREAS, the Seller desires to sell, and the Buyer desires to acquire,
certain assets of the Seller, including all documentation and rights, of any
nature or any kind whatsoever, to the internal landscapes patent, Patent No.
4,907,973, including any design modifications thereto and ancillary products of
the patent as more particularly described in Exhibit A hereto and hereby
incorporated by reference as if set forth in its entirety; and


        WHEREAS, Buyer's purchase of the internal landscapes patent, Patent No.
4,907,973, shall serve to cancel any prior obligations owed to the Seller by
the Buyer with respect to the Seller's previous assignment of the internal
landscapes patent, Patent No. 4,907,973, to the Buyer;

        NOW, THEREFORE, in consideration of the promises and the mutual
covenants and agreements hereinafter set forth, the parties hereto, intending
to be legally bound hereby, do hereby agree as follows:

                   I. SALE OF ASSETS AND RELATED TRANSACTIONS

        1.1 Sale of Asset. On the terms and subject to the conditions of this
Agreement, on the Closing Date (as that term is hereinafter defined in Section
IV hereof), the Sellers shall sell, convey, assign, transfer and deliver to
the Buyer, and the Buyer shall purchase and acquire from the Seller, the
assets, intellectual properties and rights described in Exhibit A hereto.
(Sometimes hereinafter referred to as the "Purchase Assets").

        1.2 Instruments of Conveyance and Transfer. On the Closing Date, the
Seller shall deliver to the Buyer such bills of sale, endorsements,
assignments, novations, and other good and sufficient instruments of conveyance
and assignment as set forth in Exhibit B satisfactory in form and substance to
the Buyer and its counsel, as shall be effective to vest in the Buyer, upon the
Closing Date, full and complete right, title and interest in and to the
Purchase Assets.

        1.3 Assignment of Contract and Rights. Anything in this Agreement to the
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any claim, contract, license, lease, commitment, sales or purchase order
or any claim or right or any benefit arising thereunder or resulting therefrom,
if an attempted transfer or assignment thereof, without the consent of a third
party thereto, would constitute a breach thereof or in any way affect the rights
of the Buyer or of the Seller thereunder. If such consent is not obtained, or if
an attempted transfer or assignment thereof would be ineffective or would affect
the rights of the Seller thereunder so that the Buyer would not in fact receive
all such rights, the Seller and Buyer shall cooperate so as to provide the Buyer
with all benefits under any such claims, contracts, licenses, leases,
commitments, sales or purchase orders or any claim or right or any benefit
arising thereunder or resulting therefrom, which Buyer would have received if
such consent had been forthcoming, including enforcement for the benefit of the
Buyer (at the Buyer's sole cost and 



<PAGE>   3
expense) of any and all rights of the Seller against a third party thereto
arising out of the breach or cancellation by such third party or otherwise; and
any transfer or assignment to the Buyer by the Seller of any property or
property rights or any contract or agreement which shall require the consent or
approval of any third party, shall be made subject to such consent or approval
being obtained.

             II. CONSIDERATION FOR TRANSFER OF THE PURCHASE ASSETS

        2.1     Consideration to be Paid.  The full consideration for the
Purchase Assets (hereinafter the "Purchase Price"), subject to the terms and
conditions of this Agreement, and paid as provided hereunder shall be:

                2.1.1 Upon the execution of this Agreement, Buyer shall be
obligated to pay the following amounts: $25,000 on or before August 1, 1996
and, thereafter, $25,000 on or before August 1 of each succeeding year for nine
additional years.

                        III. LIABILITIES AND OBLIGATIONS

        3.1     Buyer shall not assume and shall under no circumstances be
responsible for, and Seller shall retain and be responsible for, any current
liabilities or obligations of Seller related to the Purchase Assets. Buyer will
maintain the Patent in good standing with all taxes and fees paid in timely
fashion. 

                                IV. CLOSING DATE

<PAGE>   2
                                   IXION,INC.

                        1994 Incentive Stock Option Plan

         SECTION 1. Purpose. The purpose of the Ixion, Inc., 1994 Incentive
Stock Option Plan (the "Plan") is to enable Ixion, Inc. (the "Company") to
attract and retain the services of people with training, experience and ability
and to provide additional incentive to such persons by granting them an
opportunity to participate in the ownership of the Company.

         SECTION 2. Stock Subject to Plan. The stock subject to this Plan shall
be the Company's common stock, with a par value of $0.01 per share (the "Common
Stock"), presently authorized but unissued or now held or subsequently acquired
by the Company as treasury shares. Subject to adjustment as provided in Section
10, the aggregate amount of Common Stock reserved issuance or delivery upon
exercise of all options granted under this Plan shall not exceed 400,000 shares
of the total shares of Common Stock, as constituted on date of adoption of this
Plan by the Board of Directors. If any option granted under this Plan shall
expire or terminate for any reason without having been exercised in full, the
unpurchased shares subject thereto shall thereupon again be available for
purposes of this Plan.

         SECTION 3. Administration. The Plan shall be administered by the Board
of Directors of the Company, in accordance with the following terms and
conditions:

              3.1 General Authority. Subject to the express provisions of the
Plan, the Board of Directors shall have the authority, in its discretion, to
determine all matters relating to options to be granted under the Plan,
including the selection of individuals to be granted options, the number of
shares to be subject to each option, the exercise price, the term, whether such
options shall be immediately exercisable or shall become exercisable in
increments over time, and all other terms and conditions thereof. Grants under
this Plan to persons eligible need not be identical in any respect, even when
made simultaneously. The Board of Directors may from time to time adopt rules
and regulations relating to the administration of the Plan. The interpretation
and construction by the Board of Directors of any terms or provisions of this
Plan or any option issued hereunder, or of any rule or regulation promulgated in
connection herewith, shall be conclusive and binding on all interested parties.
The Board of Directors in its sole discretion, may grant incentive stock options
("Incentive Stock Options") as such term is defined in Section 422 of the
Internal Revenue Code of 1986, as amended, (the "Code"). The term option when
used in this Plan should refer to Incentive Stock Options only.

              3.2 Directors. A member of the Board of Directors may be eligible
to participate in or receive or hold options under this Plan; provided, however,
that said Director is also an employee of the Company, and that no member of the
Board of Directors shall vote with respect to the granting of an option
hereunder to himself or herself, as the case may be.

              3.3 Delegation to a Committee. Notwithstanding the foregoing, the
Board of Directors, if it so determines, may delegate to a committee of the
Board of Directors any or all authority for the administration of the Plan, and
thereafter references to the Board of Directors in this Plan shall be deemed to
be references to the committee to the extent provided in the resolution
establishing the committee.

1994 Incentive Stock Option Plan - Page 1
<PAGE>   3
              3.4 Persons Subject to Section 16(b). Notwithstanding anything in
the Plan to the contrary, the Board of Directors, in its absolute discretion,
may bifurcate the Plan so as to restrict, limit or condition the use of any
provision of the Plan to participants who are officers and directors subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, (the "1934
Act") without so restricting, limiting or conditioning the Plan with respect to
other participants.

              3.5 Replacement of Options. The Board of Directors, in its
absolute discretion, may grant options subject to the condition that options
previously granted at a higher or lower exercise price under the Plan be
canceled or exchanged in connection with such grant. The number of shares
covered by the new options, the exercise price, the term and the other terms and
conditions of the new option, shall be determined in accordance with the Plan
and may be different from the provisions of the canceled or exchanged options.
Alternatively, the Board of Directors may, with the agreement of the Optionee,
amend previously granted options to establish the exercise price at the then
current fair market value of the Company's Common Stock, maintaining existing
vesting and expiration dates.

              3.6 Loans to Optionees. The Board of Directors, in its absolute
discretion, may provide that the Company loan to Optionees sufficient funds to
exercise any option granted under the Plan and/or to pay withholding tax due
upon exercise of such option. The Board of Directors shall have the authority to
make such determinations at the time of grant or exercise and shall establish
repayment terms thereof, including installments, maturity and interest rate.

         SECTION 4. Eligibility. Options may be granted only to persons who, at
the time the option is granted, are employees of the Company or any of its
present or future parent or subsidiary corporations (hereafter a "Parent" or
"Subsidiary") as may be decided by the Board of Directors. Any individual to
whom an option is granted under this Plan shall be referred to hereinafter as
"Optionee". Any Optionee may receive one or more grants of options as the Board
of Directors as shall from time to time determine, and such determinations may
be different as to different Optionees and may vary as to different grants.

         SECTION 5. Terms and Conditions of Options. Options granted under this
Plan shall be evidenced by written agreements which shall contain such terms,
conditions, limitations and restrictions as the Board of Directors shall deem
advisable and which are not inconsistent with this Plan. All such options shall
include or incorporate by reference the following terms and conditions:

              5.1 Number of Shares. The maximum number of shares that may be
purchased pursuant to the exercise of each option and the price per share at
which such option is exercisable (the "exercise price") shall be as established
by the Board of Directors, provided that the exercise price of Incentive Stock
Options shall not be less than the fair market value per share of the Common
Stock at the time the option is granted, as determined in good faith by the
Board of Directors.

              5.2 Duration of Options. Subject to the restrictions contained in
Sections 7 and 9 of this Plan, the term of each option shall be established by
the Board of Directors and, if not so established, shall in no event exceed ten
(10) years from the date of grant.

              5.3 Exercisability. Each option shall prescribe the installments,
if any, in which an option granted under the Plan shall become exercisable. The
Board of Directors, in its absolute discretion, may waive or accelerate any
installment requirement contained in outstanding options. In no case may an
option be exercised as to less than 100 shares at any one time (or the remaining
shares covered by the option if less than 100) during the term of the option.
Only whole shares shall be issued pursuant to the exercise of any option.

              5.4 Incentive Stock Option. Any option which is issued as an
Incentive Stock Option under this Plan, shall, notwithstanding any other
provisions of this Plan or the option terms to the contrary, contain all of the
terms, conditions, restrictions, rights and limitations required to be an
Incentive Stock Option, and any provision to the contrary shall be disregarded.

         SECTION 6. Nontransferability of Options. Options granted under this
Plan and the rights and privileges conferred hereby may not be transferred,
assigned, pledged or hypothecated in any manner (whether by operation of law or
otherwise) other than by will or the applicable laws of descent and
distribution, and shall not be subject to execution, attachment or similar
process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise
dispose of any option under this Plan or any right or privilege conferred
hereby, contrary to the provisions hereof, or upon the sale or levy or any
attachment or similar process, such option thereupon shall terminate and become
null and void. During an Optionee's lifetime, any options granted under this
Plan are personal to him or her and are exercisable solely by such Optionee.

         SECTION 7. Certain Limitations Regarding Incentive Stock Options. The
grant of Incentive Stock Options shall be subject to the following special
limitations:

              7.1 Limitation on Amount of Grants. In no event shall any Optionee
be granted Incentive Stock Options that in the aggregate (together with all
other Incentive Stock Options granted by the Company or any Parents or
Subsidiaries) entitled the Optionee to purchase, in any calendar year during
which such options first become exercisable, stock of the Company, any Parent or
any Subsidiary having a fair market value (determined as of the time such
options are granted) in excess of $100,000 plus the amount of any unused limit
carry-over permitted under the applicable provisions of the Code.

              7.2 Grants to 10% Shareholders. Incentive Stock options may be
granted a person owning more than 10% of the total combined voting power of all
classes of stock of the Company and any Parent or Subsidiary only if (i) the
exercise price is at least 110% of the fair market value of the stock at the
time of grant, and (ii) the option is not exercisable after the expiration of
five years from the date of grant.

         SECTION 8. Exercise of Options. Options shall be exercised in
accordance with the following terms and conditions:

              8.1 Procedure. Options shall be exercised by delivery to the
Company of written notice of the number of shares with which the option is
exercised.

              8.2 Payment. Payment of the option price shall be made in full
within 5 business days of the notice of exercise of the option and shall be in
cash or bank-certified or cashier's checks, or personal check if permitted by
the Board of Directors. To the extent permitted by applicable laws and
regulations (including, but not limited to, federal tax and securities laws and
regulations), an option may be exercised by delivery of shares of Common Stock
of the Company held by the Optionee having a fair market value equal to

1994 Incentive Stock Option Plan - Page 3
<PAGE>   5
the exercise price, such fair market value to be determined in good faith by the
Board of Directors. Such payment in stock may occur in the context of a single
exercise of an option or successive and simultaneous exercises, sometimes
referred to as "pyramiding", which provides that, rather than physically
exchanging certificates for a series of exercises, bookkeeping entries will be
made pursuant to which the Optionee is permitted to retain his existing stock
certificate and a new stock certificate is issued for the net shares.

              If the Company's Common Stock is registered under the 1934 Act,
and if permitted by the Board of Directors, and to the extent permitted by
applicable laws and regulations, (including, but not limited to, federal tax and
securities laws and regulations) an option also may be exercised by delivery of
a properly executed exercise notice together with irrevocable instructions to a
broker to promptly deliver to the Company the amount of sale or loan proceeds to
pay the exercise price.

              8.3 Federal Withholding Tax Requirements. Upon exercise of an
option, the Optionee shall, upon notification of the amount due and prior to or
concurrently with the delivery of the certificates representing the shares, pay
to the Company amounts necessary to satisfy applicable federal, state and local
withholding tax requirements or shall otherwise make arrangements satisfactory
to the Company for such requirements. Such arrangements may include payment of
the appropriate withholding tax in shares of stock of the Company having a fair
market value equal to such withholding tax, either through delivery of shares
held by the Optionee or by reduction in the number of shares to be delivered to
the optionee upon exercise of such option.

         SECTION 9. Termination of Employment, Disability and Death.

              9.1 General. If the employment of the Optionee by the Company, a
Parent or a Subsidiary shall terminate for any reason other than death or
disability hereinafter provided, the option shall automatically terminate as of
the first advice or discussion thereof, and such Optionee shall thereupon have
no right to purchase any shares pursuant to such option. Further, to the extent
that the Optionee has exercised certain of his options, such stock shall be
redeemed by the Company at a price as may be determined by the Board of
Directors.

              9.2 Disability. If the employment of the Optionee by the Company,
a Parent or a Subsidiary is terminated because of the Optionee's disability (as
herein defined), the option may be exercised by the Optionee at any time prior
to the expiration of one year after the date of such termination (unless by its
terms the option sooner terminates or expires), but only if, and to the extent
the Optionee was entitled to exercise the option at the date of such
termination. For purposes of this section, an Optionee will be considered to be
disabled if the Optionee is unable to engage in any substantial gainful activity
by reason of any medically determinable mental or physical impairment which can
be expected to result in death or which has lasted or can be expected to last a
continuous period of not less than 12 months.

              9.3 Death. In the event of the death of an Optionee while in the
employ of the Company, a Parent or a Subsidiary, the option shall be exercisable
on or prior to the expiration of one year after the date of such death (unless
by its terms the option sooner terminates and expires), but only if and to the
extent the Optionee was entitled to exercise the option at date of such death
and only by the Optionee's personal representative if then subject to
administration as part of the Optionee's estate, or by the person or persons to
whom such Optionee's rights under the option shall have passed by the Optionee's
will or by the applicable laws of descent and distribution.

1994 Incentive Stock Option Plan - Page 4
<PAGE>   6
              9.4 Waiver or Extension of Time Periods. The Board of Directors
shall have the authority, prior to or within the times specified in this Section
9 for the exercise of any such option, to extend such time period or waive in
its entirety any such time period to the extent that such time period expires
prior to the expiration of the term of such option. In addition, the Board of
Directors may grant, pursuant to a specific resolution adopted at the time of
grant, modify or eliminate the time periods specified in this Section 9.
However, no Incentive Stock Option may be exercised after the expiration of ten
(10) years from the date such option is granted.

              9.5 Termination of Options. To the extent that the option of any
deceased Optionee or of any Optionee whose employment is terminated shall not
have been exercised within the limited periods prescribed in this Section 9, all
further rights to purchase shares pursuant to such option shall cease and
terminate at the expiration of such period. No Incentive Stock Option may be
exercised after the expiration of ten (10) years from the date such option is
granted, notwithstanding any provision to the contrary.

              9.6 Non-employee Optionees. Options granted to Optionees who are
not employees of the Company, a Parent or a Subsidiary at the time of grant
shall not be subject to the provisions of this Section 9, except as specifically
provided in the option.

         SECTION 10. Option Adjustments.

              10.1 Adjustments Upon Changes in Capitalization. The aggregate
number and class of shares on which options may be granted under this Plan, the
number and class of shares covered by each outstanding option and the exercise
price per share thereof (but not the total price), and all such options, shall
each be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock of the Company resulting from a split-up or
consolidation of shares or any like capital adjustment, or the payment of any
stock dividend, or any other increase or decrease in the number of shares of
Common Stock of the Company without the receipt of consideration by the Company.

              10.2 Effect of Certain Transactions. Except as provided in
subsection 10.3, upon a merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation of the Company, as a result of which
the shareholders of the Company receive cash, stock or other property in
exchange for their shares of Common Stock, any option granted hereunder shall
terminate, but, provided that the Optionee shall have the right immediately
prior to any such merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation to exercise his or her option in whole
or in part whether or not the vesting requirements set forth in the option
agreement have been satisfied.

              10.3 Conversion of Options on Stock for Stock Exchange. If the
shareholders of the Company receive capital stock of another corporation
("Exchange Stock") in exchange for their shares of Common Stock in any
transaction involving a merger, consolidation, acquisition of property or stock,
separation or reorganization, all options granted hereunder shall terminate in
accordance with the provision of subsection 10.2 unless the Board of Directors
and the corporation issuing the Exchange Stock, in their sole and arbitrary
discretion and subject to any required action by the shareholders of the Company
and such corporation, agree that all such options granted hereunder are
converted into options to purchase shares of Exchange Stock. The amount and
price of the such options shall be determined by adjusting the amount and price
of the options granted hereunder in the same proportion as used for determining
the number of shares of Exchange Stock the holders of the Common Stock receive
in such merger, consolidation,

1994 Incentive Stock Option Plan - Page 5
<PAGE>   7
acquisition of property or stock, separation or reorganization. The vesting
schedule set forth in the option agreement shall continue to apply to the
options granted for the Exchange Stock.

              10.4 Fractional Shares. In the event of any adjustment in the
number of shares covered by any option, any fractional shares resulting from
such adjustment shall be disregarded and each such option shall cover only the
number of full shares resulting from such adjustment.

              10.5 Determination of Board of Directors to be Final. All such
adjustments shall be made by the Board of Directors and its determination as to
what adjustments shall be made, and the extent thereof, shall be final, binding
and conclusive.

         SECTION 11. Securities Regulations.

              11.1 Compliance. Shares shall not be issued with respect to an
option granted under this Plan unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, any applicable state
securities laws, the Securities Act of 1933, as amended, the 1934 Act, the rules
and regulations promulgated thereunder, and the requirements of any stock
exchange upon which the shares may then be listed, and shall further be subject
to the approval of counsel for the Company with respect to such compliance.
Inability of the Company to obtain from any regulatory body having jurisdiction,
the authority deemed by the Company's counsel to be necessary for the lawful
issuance and sale of any shares hereunder, shall relieve the Company of any
liability in respect of the nonissuance or sale of such shares as to which such
requisite authority shall not have been obtained.

              11.2 Representations by Optionee. As a condition to the exercise
of an option, the Company may require the optionee to represent and warrant at
the time of any such exercise that the shares are being purchased only for
investment and without any present intention to sell or distribute such shares,
if, in the opinion of counsel for the Company, such representation is required
by any relevant provision of the laws referred to in Section 11.1. At the option
of the Company, a stop transfer order against any shares of stock may be placed
on the official stock books and records of the Company, and a legend indicating
that the stock may not be pledged, sold or otherwise transferred unless an
opinion of counsel was provided (concurred in by counsel for the Company)
stating that such transfer is not in violation of any applicable law or
regulation, may be stamped on the stock certificate in order to assure exemption
from registration. The Board of Directors may also require such other action or
agreement by the Optionees as may from time to time be necessary to comply with
the federal and state securities laws. This provision shall not obligate the
Company to undertake registration of options or stock hereunder.

         SECTION 12. Employment Rights. Nothing in this Plan or any option or
right granted pursuant hereto shall confer upon any Optionee any right to be
continued in the employment of the Company, a Parent or any Subsidiary of the
Company or to remain a director, or to interfere in any way with the right of
the Company, a Parent or any Subsidiary, in its sole discretion, to terminate
such Optionee's employment at any time or to remove the Optionee as a director
at any time.

         SECTION 13. Amendment and Termination.

              13.1 Action by Shareholders. The Plan may be terminated, modified
or amended by the shareholders of the Company.

1994 Incentive Stock Option Plan - Page 6
<PAGE>   8
              13.2 Action by Board of Directors. The Board of Directors may also
terminate the Plan, or modify or amend the Plan in such respects as it shall
deem advisable in order to conform to any changes in law or regulation
applicable thereto, or in other respects; provided, however, that the Board of
Directors may not, without further approval by the shareholders of the Company:

                   (i) Increase the number of shares in the aggregate which may
be sold pursuant to options granted under the Plan;

                   (ii) Increase the period during which options may be granted
or exercised; or

                   (iii) Change the terms of the Plan which causes the Plan to
lose its qualification as an incentive stock option plan under Section 422 of
the Code.

No termination, suspension or amendment of the Plan may, without the consent of
each optionee to whom any option shall theretofore have been granted, adversely
affect the rights of such Optionees under such options.

              13.3 Automatic Termination. Unless the Plan shall theretofore have
been terminated as herein provided, this Plan shall terminate ten (10) years
from the earlier of: (i) the date on which the Plan is adopted; or (ii) the date
on which this Plan is approved by the shareholders of the Company. No option may
be granted after such termination, or during any suspension of this Plan. The
amendment or termination of this Plan shall not, without the consent of the
Optionee, alter or impair any rights or obligations under any option theretofore
granted under this Plan.

         SECTION 14. Effective Date of the Plan. This Plan shall become
effective on the date of its adoption by the Board of Directors of the Company
and options may be granted immediately thereafter but no option may be exercised
under the Plan unless and until the Plan shall have been approved by the
shareholders within 12 months after the date of adoption of the Plan by the
Board of Directors. If such approval is not obtained within such period the Plan
and any options granted thereunder shall be null and void.

                                  Ixion, Inc.

                         Stock Option Rights Agreement
                     Under 1994 Incentive Stock Option Plan

Ixion, Inc., a Delaware corporation (the "Company"), conditionally grants to
(the "Optionee")         an incentive stock option (the "Option") under its 1994
Incentive Stock Option Plan (the "Plan") to purchase                shares of
its Common Stock, $.01 par value per share ("Common Stock"), prior to

This Agreement shall be subject to the following terms and conditions and to all
terms and conditions of the Plan:

1. The above shares will be granted upon successful completion by the individual
or by the Company of the objectives described herein:









Should any disagreement arise as to the extent of contribution or to completion
of said objective that is required in the conditional grant, the Stock Option
Committee may grant instead a percentage of this option which, in that
Committee's sole discretion, it deems as a fair assessment of the objective
which has been achieved.

2. The Option's exercise price shall be          Dollars and        Cents ($   )
per share. This option shall not be exercisable until the Optionee has completed
(6) months continuous employment beyond the date on which the Stock Option
Committee agrees the conditions have been met. At the end of the six month
period, his or her option shall be exercisable to the extent of not more than
one thirty-sixth (1/36) of the number of shares subject to purchase under this
option. At the end of each additional one (1) full month of continuous
employment, this option shall be exercisable to the extent of an additional one
thirty-sixth (1/36) of the number of shares subject to purchase under this
option, until the finally granted option has vested in full after three (3)
further years of continuous employment at Ixion, Inc. Upon termination of
employment for any reason, vesting of this option pursuant to this paragraph 2
shall immediately cease, notwithstanding any period after termination during
which previously vested options may be exercisable.
<PAGE>   3
Strictly Confidential between Optionee
and Ixion Stock Option Committee

without cause that his or her rights will afford these, and only these,
settlements and remedies under law in only these amounts:

         (a) If the Optionee is terminated without cause by the Company prior to
         completion of these Performance conditions by either the Company or by
         the Optionee, any options conditionally granted will be null and void.

         (b) If the Optionee -- when terminated without cause by the Company --
         has satisfied both the performance conditions and the 6-month period of
         employment until the first opportunity to exercise options, five
         percent (5%) of the options for which performance has been completed
         will be exercisable between the 12th and 14th months following the date
         of termination.

12. In the event the Company is merged or consolidated with another corporation
and the Company is not the surviving corporation, or in the event all or
substantially all of the assets or more than 50% of the outstanding voting stock
of the Company is acquired by any other corporation, or in case of a
reorganization or liquidation of the Company, the Board of Directors of the
Company, or the board of directors of any corporation assuming the obligations
of the Company, shall determine in its sole discretion either (i) to make
appropriate provision for the protection of the Option by (x) substituting on an
equitable basis, which shall be determined by the Company, appropriate Common
Stock of the Company or Common Stock of the merged, consolidated or otherwise
reorganized corporation which will be issuable in respect to the shares of
Common Stock of the Company, and (y) enabling the Optionee to retain the excess,
if any, of the aggregate fair market value of the shares subject to the Option
immediately after such substitution over the Option price thereof, or (ii) upon
written notice to the Optionee, to provide that the remaining portion of the
unexercised Option must be exercised within a specified number of days of the
date of such notice or it will be terminated; provided, however, that the
Company shall not provide any additional benefits to the Optionee other than
those benefits set forth in this Section 12. In any such case, the Board of
Directors may, in its discretion, accelerate the exercise date of the Option.

                    Ixion, Inc. Incentive Stock Option Plan

                        GRANT OF INCENTIVE STOCK OPTION

Date of Grant: _____________, 1994.

                THIS GRANT, dated as of the date of grant first stated above
(the "Date of Grant"), is delivered by Ixion, Inc., a Delaware corporation
("Ixion") to __________ (the "Grantee"), who is an employee of Ixion or one of
its subsidiaries (the Grantee's employer is sometimes referred to herein as the
"Employer").

                WHEREAS, the Board of Directors of Ixion (the "Board") on
January 1, 1994, adopted, with subsequent stockholder approval, the Ixion, Inc.
Incentive Stock Option Plan (the "Plan");

                WHEREAS, the Plan provides for the granting of incentive stock
options by the Board to directors, officers and key employees of Ixion or any
subsidiary of Ixion (excluding directors and officers who are not employees) to
purchase, or to exercise certain rights with respect to, shares of the Common
Stock of Ixion, par value $.01 per share (the "Stock"), in accordance with the
terms and provisions thereof; and

                WHEREAS, the Board considers the Grantee to be a person who is
eligible for a grant of incentive stock options under the Plan, and has
determined that it would be in the best interest of Ixion to grant the incentive
stock options documented herein.

                NOW, THEREFORE, the parties hereto, intending to be legally
bound hereby, agree as follows:

1.      Grant of Option

                Subject to the terms and conditions hereinafter set forth,
Ixion, with the approval and at the direction of the Board, hereby grants to the
Grantee, as of the Date of Grant, an option to purchase up to          shares
of Stock at a price of $____ per share ("Exercise Price"), the fair market
value. Such option is hereinafter referred to as the "Option" and the shares
of stock purchasable upon exercise of the Option are hereinafter sometimes
referred to as the "Option Shares." The Option is intended by the parties
hereto to be, and shall be treated as an incentive stock option (as such term 
is defined under Section 422 of the Internal Revenue Code of 1986).

2.      Incremental Exercise

                Subject to such further limitations as are provided herein, the
Option shall become exercisable in thirty-six (36) monthly increments as
provided herein; the Grantee having the right hereunder to purchase from Ixion
the following number of Option Shares upon exercise of the Option, on and after
the following dates, in cumulative fashion:

                (a) on and after every month beginning with the Date of Grant,
up to 1/36 (ignoring fractional shares) of the total number of Option Shares
granted herein;

                (b) on and after the thirty-sixth (36th) month of the Date of
Grant, the remaining Option Shares.

Grant of Incentive Stock Option - Page 1


<PAGE>   3
3.      Termination of the Option

        (a) The Option and all rights hereunder with respect thereto, to the
extent such rights shall not have been exercised, shall terminate and become
null and void after the expiration of ten (10) years from the Date of Grant (the
"Option Term").

        (b) Upon the occurrence of the Grantee's ceasing for any reason to be
employed by the Employer (such occurrence being a "termination of the Grantee's
employment"), the Option, to the extent not previously exercised, shall
terminate and become null and void immediately upon such termination of the
Grantee's employment, except in a case where the termination of the Grantee's
employment is by reason of disability or death.

        Upon termination of the Grantee's employment by reason of disability or
death, the Option may be exercised during the following periods, but only to the
extent that the Option was outstanding and exercisable on any such date of
disability or death; (i) the one-year period following the date of such
termination of the Grantee's employment in the case of a disability (within the
meaning of Section 22(e)(3) of the Code), and (ii) the six-month period
following the date of issuance of letters testamentary or letters of
administration to the executor or administrator of a deceased Grantee, in the
case of the Grantee's death during his employment by the Employer, but not later
than one year after the Grantee's death, or in the case of disability other than
as described in (i) above. In no event, however, shall any such period extend
beyond the Option Term.

        (c) In the event of the death of the Grantee, the Option may be
exercised by the Grantee's legal representative(s), but only to the extent that
the Option would otherwise have been exercisable by the Grantee.

        (d) A transfer of the Grantee's employment between Ixion and any
subsidiary of Ixion, or between any subsidiaries of Ixion, shall not be deemed
to be a termination of the Grantee's employment.

        (e) Notwithstanding any other provisions set forth herein or in the
Plan, if the Grantee shall (i) commit any act of malfeasance or wrongdoing
affecting Ixion or any subsidiary of Ixion, (ii) breach any covenant not to
compete, or employment contract, with Ixion or any subsidiary of Ixion, or (iii)
engage in conduct that would warrant the Grantee's discharge for cause
(excluding general dissatisfaction with the performance of the Grantee's duties
but including any act of disloyalty or any conduct clearly tending to bring
discredit upon or any subsidiary of Ixion), any unexercised portion of the
Option shall immediately terminate and be void.

        (f) Upon the termination of the Grantee's employment, any and all
options exercised to date by said Grantee shall be redeemed by the Company at a
price no less than two times the Optionee's Exercise Price as established
herein, provided the Company is not yet a public company. In the event the
Company should become a public company, Grantee shall have the right to retain
all options exercised, irrespective of Grantee's employment status with the
Company.

4.      Exercise of Options

        (a) The Grantee may exercise the Option with respect to all or any part
of the number of Option Shares then exercisable hereunder by giving the Company
written notice of intent to exercise. The notice of exercise shall specify the
number of Option Shares as to which the Option is to be exercised and the date
of exercise thereof, which

Grant of Incentive Stock Option - Page 2


<PAGE>   4


date shall be at least five days after the giving of such notice unless an
earlier time shall have been mutually agreed upon.

        (b) Full payment (in U.S. dollars) by the Grantee of the option price
for the Option Shares purchased shall be made on or before the exercise date
specified in the notice of exercise in cash, or, with the prior written consent
of the Board, in whole or in part through the surrender of previously acquired
shares of Stock at their fair market value on the exercise date.

        On the exercise date specified in the Grantee's notice or as soon
thereafter as is practicable, Ixion shall cause to be delivered to the Grantee,
a certificate or certificates for the Option Shares then being purchased (out of
theretofore unissued Stock or required Stock, as Ixion may elect) upon full
payment for such Option Shares. The obligation of Ixion to deliver Stock shall,
however, be subject to the condition that if at any time the Board shall
determine in its discretion that the listing, registration or qualification of
the Option or the Option Shares upon any securities exchange or under any state
or federal law, or the consent or approval of any governmental regulatory body,
is necessary or desirable as a condition of, or in connection with, the Option
or the issuance of purchase of Stock thereunder, the Option may not be exercised
in whole or in part unless such listing, registration, qualification, consent or
approval shall have been effected or obtained free of any conditions not
acceptable to the Board.

        (c) If the Grantee fails to pay for any of the Option Shares specified
in such notice or fails to accept delivery thereof, the Grantee's right to
purchase such Option shares may be terminated by Ixion. The date specified in
the Grantee's notice as the date of exercise shall be deemed the date of
exercise of the Option, provided that payment in full for the Option Shares to
be purchased upon such exercise shall have been received by such date.

5.      Adjustment of and Changes in Stock of Ixion

        In the event of a reorganization, recapitalization, change of shares,
stock split, spin-off, stock dividend, reclassification, subdivision or
combination of shares, merger, consolidation, rights offering, or any other
change in the corporate structure of shares of capital stock of Ixion, the Board
shall make such adjustment as it deems appropriate in the number and kind of
shares of Stock subject to the Option or in the option price; provided, however,
that no such adjustment shall give the Grantee any additional benefits under the
Option.

6.      Fair Market Value

        As used herein, the "fair market value" of a share of Stock shall be
average of the high and low sale prices per share of Stock on the American Stock
Exchange, composite tape or other recognized market source, as determined by the
Board, on the applicable date of reference hereunder, or if there is no sale on
such date, then the average of such high and low sale prices on the last
previous day on which a sale is reported.

7.      No Rights of Stockholders

        Neither the Grantee nor any personal representative shall be, or shall
have any of the rights and privileges of, a stockholder of Ixion with respect to
any shares of Stock purchasable or issuable upon the exercise of the Option, in
whole or in part, prior to the date of exercise of the Option.

8.      Non-Transferability of Option

        During the Grantee's lifetime, the Option hereunder shall be exercisable
only by the Grantee of any guardian or legal representative of the Grantee, and
the Option shall not be transferable except, in case of the death of the Grantee
by will or the laws of descent and distribution, nor shall the Option be subject
to attachment, execution or other similar process. In no event of (a) any
attempt by the Grantee to alienate, assign, pledge, hypothecate or otherwise
dispose of the Option, except as provided for herein, or (b) the levy of any
attachment, execution or similar process upon the rights or interest hereby
conferred, Ixion may terminate the Option by notice to the Grantee and it shall
thereupon become null and void.

9.      Employment Not Affected

        The granting of the Option nor its exercise shall not be construed as
granting to the Grantee any right with respect to continuance of employment of
the Employer. Except as may otherwise be limited by a written agreement between
the Employer and the Grantee, the right of the Employer to terminate at will the
Grantee's employment with it at any time (whether by dismissal, discharge,
retirement or otherwise) is specifically reserved by Ixion, as the Employer or
on behalf of the Employer (whichever the case may be), and acknowledged by the
Grantee.

10.     Amendment of Option

        The Option may be amended by the Board, at any time (if the Board
determines, in its sole discretion, that amendment is necessary or advisable in
the light of any addition to or change in the Internal Revenue Code of 1986 or
in the regulations issued thereunder, or any federal or state securities law or
the law of regulation, which change occurs after the Date of Grant and by its
terms applies to the Option); or (ii) other than in the circumstances described
in clause (i), with the consent of the Grantee.

11.     Notice

        Any notice to Ixion provided for in this instrument shall be addressed
to it in care of David M. Otto, 6500 Columbia Center, 701 Fifth Avenue, Seattle,
Washington 98104-7003, and any notice to the Grantee shall be addressed to the
Grantee at the current address shown on the payroll records of the Employer. Any
notice shall be deemed to be duly given if any when properly addressed and
posted by registered or certified mail, postage prepaid.

12.     Incorporation of Plan by Reference

        The Option is granted pursuant to the terms of the Plan, the terms of
which are incorporated herein by reference, and the Option shall in all respects
be interpreted in accordance with the Plan. The Board shall interpret and
construe the Plan and this instrument, and its interpretations and
determinations shall be conclusive and binding on the parties hereto an any
other person claiming an interest hereunder, with respect to any issue arising
hereunder or thereunder.

13.     Governing Law

        The validity, construction, interpretation and effect of this instrument
shall exclusively be governed by and determined in accordance with the laws of
the state of Washington, except to the extent preempted by federal law, which
shall to the extent govern.

        IN WITNESS WHEREOF, Ixion has caused its duly authorized officers to

                          ASSIGNMENT OF PATENT RIGHTS

         THIS ASSIGNMENT is made as of the date set forth below by and between
DAVID C. HON, a citizen of the United States having an office at 1335 North
Northlake Way #102, Seattle, Washington 98103 and IXION, INC., a Delaware

98109 (the "Assignee").

         WHEREAS, Assignor is the owner of U.S. Patent No.4,907,973 entitled
"Expert system simulator for modelling realistic internal environments and
performance" and all corresponding foreign patents and patent applications (the
"Patent Rights"), including but not limited to those set forth on Schedule I
attached hereto;

         WHEREAS, Assignee is desirous of acquiring the entire and exclusive
right, title and interest in and to the Patent Rights and the underlying
inventions described therein, in the United States and throughout the world.

         NOW, THEREFORE, for good and valuable consideration, receipt of which
is hereby acknowledged by Assignor, Assignor hereby assigns, transfers and
conveys to Assignee and Assignee's successors and assigns all of Assignor's
right, title, and interest throughout the world in and to the Patent Rights, the
underlying inventions described therein and all existing and future design
modifications and improvements thereon, and any and all Letters Patent whether
U.S. or foreign that are or may be granted therefrom including without
limitation any extensions, continuations, continuations-in-part, divisions,
reissues, reexaminations, and renewals thereof, or other equivalents thereof,
and further, all rights and privileges pertaining to the Patent Rights and any
and all Letters Patent whether U.S. or foreign that are or may be granted
therefrom including without limitation the right, if any, to sue or bring other
actions for past, present and future infringement thereof.

         Assignor further assigns to and empowers Assignee, its successors,
assigns or nominees, all rights to make applications for patents or other forms
of protection for said inventions, design modifications and improvements and to
prosecute such applications as well as to claim and receive the benefit of the
right of priority provided by the International Convention for the Protection of
Industrial Property, as amended, or by any convention which may henceforth be
substituted for it, and the right to invoke and claim such right of priority
without further written or oral authorization.

         Assignor further agrees that Assignor will, without charge to Assignee,
but at Assignee's expense: (a) cooperate with Assignee in the prosecution of
U.S. patent applications and foreign counterparts on the inventions and any
design modifications and improvements; (b) execute, verify, acknowledge and
deliver all such further papers, including patent applications and instruments
of transfer; and (c) perform such other acts as Assignee lawfully may request to

modifications and improvements in any and all countries, and to vest title
thereto in Assignee, or Assignee's successors and assigns.

         In the event that Assignee is unable for any reason whatsoever to
secure Assignor's signature to any document it is entitled to under the
preceding paragraph, Assignor hereby irrevocably designates and appoints
Assignee and its duly authorized officers and agents, as his agents and
attorneys-in-fact to act for and on his behalf and instead of him, to execute
and file any such document and to do all other lawfully permitted acts to
further the purposes of the foregoing with the same legal force and effect as if
executed by Assignee.

         IN TESTIMONY WHEREOF, the undersigned Assignor has hereunto signed his
name this 18th day of May, 1996.

                   INTERACT MEDICAL TECHNOLOGIES CORPORATION
                     1996 STOCK OPTION/STOCK ISSUANCE PLAN

                                  ARTICLE ONE
                                    GENERAL

         I. PURPOSE OF THE PLAN

            This 1996 Stock Option/Stock Issuance Plan ("Plan") is intended to
promote the interests of Interact Medical Technologies Corporation, a Delaware
corporation (the "Corporation"), by providing (i) key employees (including
officers) of the Corporation (or its parent or subsidiary corporations) who are
responsible for the management, growth and financial success of the Corporation
(or its parent or subsidiary corporations), (ii) Directors and (iii) consultants
and other independent contractors who provide valuable services to the
Corporation (or its parent or subsidiary corporations) with the opportunity to
acquire a proprietary or increase their proprietary interest in the Corporation
as an incentive for them to remain in the service of the Corporation (or its
parent or subsidiary corporations).

         II. GENERAL

            A. The Plan shall become effective on the first date on which shares
of the Corporation's Common Stock are registered under Section 12(g) of the
Securities Exchange Act of 1934, as amended (the "1934 Act"). Such date is
hereby designated as the "Effective Date" of this Plan.

            B. This Plan shall serve as the successor to all prior stock option
or stock issuance plans (together, the "Predecessor Plans"), and no further
option grants or share issuances shall be made under the Predecessor Plans from
and after the Effective Date. Each outstanding option or share issuances under
the Predecessor Plans immediately prior to the Effective Date are hereby
incorporated into this Plan and shall accordingly be treated as outstanding
options or share issuance under this Plan. However, each such option or share
issuance shall continue to be governed solely by the terms and conditions of the
instrument evidencing such grant or issuance, and, except as otherwise expressly
provided herein, no provision of this Plan shall affect or otherwise modify the
rights or obligations of the holders of such incorporated options or shares with
respect to their acquisition of shares of the Corporation's Common Stock or
otherwise modify the rights or obligations of the holders of such options or
shares.

            C. For purposes of this Plan, the following provisions shall be
applicable in determining the parent and subsidiary corporations of the
Corporation:
<PAGE>   3
                Any corporation (other than the Corporation) in an unbroken
         chain of corporations ending with the Corporation shall be considered
         to be a PARENT of the Corporation, provided each such corporation in
         the unbroken chain (other than the Corporation) owns, at the time of
         the determination, stock possessing fifty percent (50%) or more of the
         total combined voting power of all classes of stock in one of the other
         corporations in such chain.

                Each corporation (other than the Corporation) in an unbroken
         chain of corporations beginning with the Corporation shall be
         considered to be a SUBSIDIARY of the Corporation, provided each such
         corporation (other than the last corporation) in the unbroken chain
         owns, at the time of the determination, stock possessing fifty percent
         (50%) or more of the total combined voting power of all classes of
         stock in one of the other corporations in such chain.

             D. Neither the grant of options nor the issuance of any shares
pursuant to this Plan shall in any way affect the right of the Corporation to
adjust, reclassify, reorganize or otherwise change its capital or business
structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

             E. The holder of an option grant under this Plan shall have none of
the rights of a stockholder with respect to any shares subject to such option
until such individual shall have exercised the option, paid the exercise price
for the purchased shares and been issued a stock certificate for such shares.

        III. STRUCTURE OF THE PLAN

             A. The Plan shall be divided into two components: the Option Grant
Program specified in Article Two; and the Stock Issuance Program specified in
Article Three. Under the Option Grant Program, eligible individuals may be
granted options to purchase shares of the Corporation's Common Stock at not less
than 85% of the fair market value of such shares on the grant date. Under the
Stock Issuance Program, eligible individuals may be allowed to purchase shares
of the Corporation's Common Stock at discounts from the fair market value of
such shares of up to 15%. Such shares may be issued as fully-vested shares or as
shares to vest over time.

             B. The provisions of Articles One and Four of the Plan, except as
otherwise expressly provided, shall apply to the Option Grant Program and the
Stock Issuance Program and shall accordingly govern the interests of all
individuals in the Plan.

         IV. ADMINISTRATION OF THE PLAN

             A. This Plan shall be administered by the Board of Directors (the
"Board") or a committee ("Committee") of two (2) or more Board members who
assume

                                      -2-
<PAGE>   4
full responsibility for the administration of the Plan (the "Plan
Administrator"). Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time.

            B. The Plan Administrator shall have full power and authority
(subject to the express provisions of the Plan) to establish such rules and
regulations as it may deem appropriate for the proper administration of the Plan
and to make such determinations under, and issue such interpretations of, the
Plan and any outstanding option grants or stock issuances as it may deem
necessary or advisable. Decisions of the Plan Administrator shall be final and
binding on all parties who have an interest in the Plan or any outstanding
option or stock issuance.

         V. OPTION GRANTS AND STOCK ISSUANCES

            A. Except as set forth in paragraph B. hereof, the persons eligible
to receive stock issuances under the Stock Issuance Program ("Participant")
and/or option grants pursuant to the Option Grant Program ("Optionee") are as
follows:

               (i) officers, directors and other employees of the Corporation
         (or its parent or subsidiary corporations) who render services which
         contribute to the management, growth and financial success of the
         Corporation (or its parent or subsidiary corporations);

               (ii) those consultants or other independent contractors who
         provide valuable services to the Corporation (or its parent or
         subsidiary corporations).

            B. The Plan Administrator shall have full authority to determine,
(I) with respect to the option grants made under the Option Grant Program, which
eligible individuals are to receive option grants, the number of shares to be
covered by each such grant, whether the granted option is to be an incentive
stock option ("Incentive Option") which satisfies the requirements of Section
422 of the Internal Revenue Code of 1986, as amended (the "Internal Revenue
Code") or a non-statutory option not intended to meet such requirements, the
time or times at which and the circumstances under which each granted option is
to become exercisable and the maximum term for which the option may remain
outstanding and (II), with respect to stock issuances under the Stock Issuance
Program, the number of shares to be issued to each Participant, the vesting
schedule and conditions to vesting (if any) to be applicable to the issued
shares, and the consideration to be paid by the individual for such shares.

                                      -3-
<PAGE>   5
            C. Notwithstanding any other provision of this Plan, no individual
shall be granted options to acquire more than five hundred thousand (500,000)
shares of stock hereunder.

        VI. STOCK SUBJECT TO THE PLAN

            A. Shares of the Corporation's Common Stock shall be available for
issuance under the Plan and shall be drawn from either the Corporation's
authorized but unissued shares of Common Stock or from reacquired shares of
Common Stock, including shares repurchased by the Corporation on the open
market. The maximum number of shares of Common Stock which may be issued over
the term of the Plan shall not exceed 1,000,000 shares, subject to adjustment
from time to time in accordance with the provisions of this Section VI. Such
authorized number of shares is comprised of (i) 400,000 shares previously
authorized under the Predecessor Plans, (ii) an additional 600,000 shares.

            B. Should one or more outstanding options under this Plan (including
outstanding options under the Predecessor Plans incorporated into this Plan)
expire or terminate for any reason prior to exercise in full (including any
option cancelled in accordance with the cancellation-regrant provisions of
Section III of Article Two of the Plan), then the shares subject to the portion
of each option not so exercised shall be available for subsequent option grant
or share issuance under this Plan. Shares subject to any option or portion
thereof surrendered or cancelled in accordance with Section I.C. of Article Four
and all shares issuances under the Plan, whether or not such shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan or otherwise surrendered for cancellation, shall reduce on a
share-for-share basis the number of shares of the same class of Common Stock
available for subsequent option grant or stock issuance under the Plan. In
addition, should the exercise price of an outstanding option under the Plan be
paid with shares of Common Stock or should shares of Common Stock otherwise
issuable under the Plan be withheld by the Corporation in satisfaction of the
withholding taxes incurred in connection with the exercise of an outstanding
option under the Plan, then the number of shares of Common Stock available for
issuance under the Plan shall be reduced by the gross number of shares for which
the option is exercised.

            C. In the event any change is made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares, conversion or other change affecting
the outstanding Common Stock, or any class of Common Stock as a class, without
the Corporation's receipt of consideration, then appropriate adjustments shall
be made to (i) the number and/or class of shares issuable under the Plan, (ii)
the number and/or class of shares and price per share in effect under each
outstanding option under this Plan (including outstanding options incorporated
into this Plan from the Predecessor Plans). Such adjustments to the outstanding
options are to be effected in a manner which shall

                                      -4-
<PAGE>   6
preclude the enlargement or dilution of rights and benefits under such options.
The adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

            D. Common Stock issuable under the Option Grant Program or the Stock
Issuance Program may be subject to such restrictions on transfer, repurchase
rights or such other restrictions as determined by the Plan Administrator.

                                  ARTICLE TWO
                              OPTION GRANT PROGRAM

         I. TERMS AND CONDITIONS OF OPTIONS

            Options granted to Employees of the Corporation or its parent or
subsidiary corporations pursuant to this Article Two shall be authorized by
action of the Plan Administrator and may, at the Plan Administrator's
discretion, be either Incentive Options or non-statutory options. Individuals
who are not Employees of the Corporation or its parent or subsidiary
corporations may only be granted non-statutory options. Each granted option
shall be evidenced by one or more instruments in the form approved by the Plan
Administrator; provided, however, that each such instrument shall comply with
the terms and conditions specified below. Each instrument evidencing an
Incentive Option shall, in addition, be subject to the applicable provisions of
Section II of this Article Two.

            A. Option Price.

               (i) In General. The option price per share shall be fixed by the
         Plan Administrator. In no event, however, shall the price for any share
         be less than eighty-five percent (85%) of the fair market value of that
         share on the date of the option grant.

               (ii) 10% Stockholder. If any individual to whom an option is
         granted is the owner of stock (as determined under Section 424(d) of
         the Internal Revenue Code) possessing 10% or more of the total combined
         voting power of all classes of stock of the Corporation or any one of
         its parent or subsidiary corporations, then the option price per share
         shall not be less than one hundred and ten percent (110%) of the fair
         market value per share of Common Stock on the grant date.

               (iii) How Payable. The option price shall become immediately due
         upon exercise of the option and, subject to the provisions of Article
         Four, Section III and the instrument evidencing the grant, shall be
         payable in one of the following alternative forms specified below:

                                      -5-
<PAGE>   7
                      - full payment in cash or check drawn to the Corporation's
         order;

                      - full payment in shares of Common Stock held for at least
         six (6) months and valued at fair market value on the Exercise Date (as
         such term is defined below);

                      - full payment in a combination of shares of Common Stock
         held for at least six (6) months and valued at fair market value on the
         Exercise Date and cash or check; or

                      - full payment through a broker-dealer sale and remittance
         procedure pursuant to which the Optionee (I) shall provide irrevocable
         written instructions to a designated brokerage firm to effect the
         immediate sale of the purchased shares and remit to the Corporation,
         out of the sale proceeds available on the settlement date, sufficient
         funds to cover the aggregate option price payable for the purchased
         shares plus all applicable Federal and State income and employment
         taxes required to be withheld by the Corporation in connection with
         such purchase and (II) shall provide written directives to the
         Corporation to deliver the certificates for the purchased shares
         directly to such brokerage firm in order to complete the sale
         transaction.

            For purposes of this subparagraph (iii), the Exercise Date shall be
the date on which written notice of the option exercise is delivered to the
Corporation. Except to the extent the sale and remittance procedure is utilized
in connection with the exercise of the option, payment of the option price for
the purchased shares must accompany such notice.

            B. Term and Exercise of Options. Each option granted under this
Article Two shall have such term as may be fixed by the Plan Administrator, be
exercisable at such time or times and during such period, and on such
conditions, as is determined by the Plan Administrator and set forth in the
stock option agreement evidencing the grant. No such option, however, shall have
a maximum term in excess of ten (10) years from the grant date and no option
granted to a 10% stockholder shall have a maximum term in excess of five (5)
years from the grant date. During the lifetime of the Optionee, the option
(together with any related stock appreciation right) shall, unless otherwise
expressly permitted by the Plan Administrator in its sole discretion, be
exercisable only by the Optionee and shall not be assignable or transferable by
the Optionee otherwise than by will or by the laws of descent and distribution
following the Optionee's death.

                                      -6-

<PAGE>   8
         C. Termination of Service.

            (i) Except to the extent otherwise provided pursuant to Section V of
      this Article Two, the following provisions shall govern the exercise
      period applicable to any outstanding options under this Article Two which
      are held by the Optionee at the time of his or her cessation of Service or
      death.

            - Should an Optionee's Service terminate for any reason (including
      death or permanent disability as defined in Section 22(e)(3) of the
      Internal Revenue Code) while the holder of one or more outstanding options
      under the Plan, then none of those options shall (except to the extent
      otherwise provided pursuant to Section V of this Article Two) remain
      exercisable beyond the later of (i) the limited post-Service period
      designated by the Plan Administrator at the time of the option grant and
      set forth in the option agreement; or (ii) (A) ninety (90) days from the
      date of termination if termination was caused by other than the death or
      disability (as defined in Section 22(e)(3) of the Internal Revenue Code)
      of such Optionee or (B) twelve (12) months from the date of termination if
      termination was caused by death or disability of Optionee.

            - Any option granted to an Optionee under this Article Two and
      exercisable in whole or in part on the date of the Optionee's death may be
      subsequently exercised, by the personal representative of the Optionee's
      estate or by the person or persons to whom the option is transferred
      pursuant to the Optionee's will or in accordance with the laws of descent
      and distribution, provided and only if such exercise occurs prior to the
      earlier of (i) the first anniversary of the date of the Optionee's death
      or (ii) the specified expiration date of the option term. Upon the
      occurrence of the earlier event, the option shall terminate and cease to
      be exercisable.

            - Under no circumstances, however, shall any such option be
      exercisable after the specified expiration date of the option term.

            - During the limited post-Service period of exercisability, the
      option may not be exercised for more than the number of shares for which
      the option is exercisable on the date the Optionee's Service terminates.
      Upon the expiration of such limited exercise period or (if earlier) upon
      the expiration of the option term, the option shall terminate and cease to
      be exercisable.

            (ii) The Plan Administrator shall have complete discretion,
      exercisable either at the time the option is granted or at any time while
      the option remains outstanding, to permit one or more options

                                      -7-
<PAGE>   9
      held by the Optionee under this Article Two to be exercised, during
      the limited period of exercisability provided under subparagraph (i)
      above, not only with respect to the number of shares for which each such
      option is exercisable at the time of the Optionee's cessation of Service
      but also with respect to one or more subsequent installments of
      purchasable shares for which the option would otherwise have become
      exercisable had such cessation of Service not occurred.

            (iii) For purposes of the foregoing provisions of this Section I.C.
      of Article Two (and for all other purposes under the Plan):

            - The Optionee shall (except to the extent otherwise specifically
      provided in the applicable option or issuance agreement) be deemed to
      remain in the SERVICE of the Corporation for so long as such individual
      renders services on a periodic basis to the Corporation (or any parent or
      subsidiary corporation) in the capacity of an Employee, a non-employee
      member of the Board or an independent consultant or advisor.

            - The Optionee shall be considered to be an EMPLOYEE for so long as
      he or she remains in the employ of the Corporation or one or more parent
      or subsidiary corporations, subject to the control and direction of the
      employer entity not only as to the work to be performed but also as to the
      manner and method of performance.

         II. INCENTIVE OPTIONS

             The terms and conditions specified below shall be applicable to all
Incentive Options granted under this Article Two. Incentive Options may only be
granted to individuals who are Employees of the Corporation. Options which are
specifically designated as "non-statutory" options when issued under the Plan
shall not be subject to such terms and conditions.

             A. Option Price. The option price per share of any share of Common
Stock subject to an Incentive Option shall in no event be less than one hundred
percent (100%) of the fair market value of such share of Common Stock on the
grant date.

             B. Dollar Limitation. The aggregate fair market value (determined
as of the respective date or dates of grant) of the Common Stock for which one
or more options granted to any Employee after December 31, 1986 under this Plan
(or any other option plan of the Corporation or its parent or subsidiary
corporations) may for the first time become exercisable as incentive stock
options under the Federal tax laws during any one calendar year shall not exceed
the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee
holds two or more such options which become exercisable for the first time in
the same calendar year, the foregoing limitation on the

                                      -8-
<PAGE>   10
exercisability of such options as Incentive Options under the Federal tax laws
shall be applied on the basis of the order in which such options are granted.

             C. During the lifetime of the Optionee, the incentive stock option
(together with any related stock appreciation right) shall be exercisable only
by the Optionee and shall not be assignable or transferable by the Optionee
otherwise than by will or by the laws of descent and distribution following the
Optionee's death.

             D. Except as modified by the preceding provisions of this Section
II, the provisions of Articles One, Two and Four of the Plan shall apply to all
Incentive Options granted hereunder.

        III. CANCELLATION AND REGRANT OF OPTIONS

             The Plan Administrator shall have the authority to effect, at any
time and from time to time, with the consent of the affected Optionees, the
cancellation of any or all outstanding options under this Article Two (including
outstanding options under the Predecessor Plans incorporated into this Plan) and
to grant in substitution new options under this Article Two covering the same or
different numbers of shares of Common Stock but having an option price for each
share which is not less than (i) eighty-five percent (85%) of the fair market
value of such share on the new grant date or (ii) one hundred percent (100%) of
such fair market value in the case of an Incentive Option.

        IV.  STOCK APPRECIATION RIGHTS

             A. Provided and only if the Plan Administrator determines in its
discretion to implement the stock appreciation right provisions of this Section
IV, one or more Optionees under the Option Grant Program may be granted the
right, exercisable upon such terms and conditions as the Plan Administrator may
establish, to surrender all or part of an unexercised option under this Article
Two in exchange for a distribution from the Corporation in an amount equal to
the excess of (i) the fair market value (on the option surrender date) of the
number of shares in which the Optionee is at the time vested under the
surrendered option (or surrendered portion thereof) over (ii) the aggregate
option price payable for such vested shares.

             B. No surrender of an option shall be effective hereunder unless it
is approved by the Plan Administrator. If the surrender is so approved, then the
distribution to which the Optionee shall accordingly become entitled under this
Section IV may be made in shares of any class of Common Stock valued at fair
market value on the option surrender date, in cash, or partly in shares and
partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.

             C. If the surrender of an option is rejected by the Plan
Administrator, then the Optionee shall retain whatever rights the Optionee had
under the surrendered option (or surrendered portion thereof) on the option
surrender date and may exercise

                                      -9-
<PAGE>   11
such rights at any time prior to the later of (i) five (5) business days after
the receipt of the rejection notice or (ii) the last day on which the option is
otherwise exercisable in accordance with the terms of the instrument evidencing
such option, but in no event may such rights be exercised more than ten (10)
years after the date of the option grant.

             D. One or more officers of the Corporation subject to the
short-swing profit restrictions of the Federal securities laws may, in the Plan
Administrator's sole discretion, be granted limited stock appreciation rights in
tandem with their outstanding options under this Article Two. Upon the
occurrence of a Hostile Take-Over (as defined in Section II.B. of Article Four)
effected at any time when the Corporation's outstanding Common Stock is
registered under Section 12(g) of the 1934 Act, each outstanding option with
such a limited stock appreciation right in effect for at least six (6) months
shall automatically be cancelled, to the extent such option is at the time
exercisable for fully-vested shares of Common Stock. The Optionee shall in
return be entitled to a cash distribution from the Corporation in an amount
equal to the excess of (i) the Take-Over Price of the vested shares of Common
Stock at the time subject to the cancelled option (or cancelled portion of such
option) over (ii) the aggregate exercise price payable for such shares. The cash
distribution payable upon such cancellation shall be made within five (5) days
following the consummation of the Hostile Take-Over. Neither the approval of the
Plan Administrator nor the consent of the Board shall be required in connection
with such option cancellation and cash distribution. The balance of the option
(if any) shall continue to remain outstanding and exercisable in accordance with
the terms of the instrument evidencing such grant.

             E. The shares of Common Stock subject to any option surrendered or
cancelled for an appreciation distribution pursuant to this Section IV shall NOT
be available for subsequent option grant under the Plan.

         V.  EXTENSION OF EXERCISE PERIOD

             The Plan Administrator shall have full power and authority to
extend the period of time for which any option granted under this Article Two is
to remain exercisable following the Optionee's cessation of Service or death
from the limited period in effect under Section I.C.(i) of this Article Two to
such greater period of time as the Plan Administrator shall deem appropriate;
provided, however, that in no event shall such option be exercisable after the
specified expiration date of the option term.

                             STOCK ISSUANCE PROGRAM

        I. TERMS AND CONDITIONS OF STOCK ISSUANCES

           Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate purchases without any intervening stock option
grants. The issued shares shall be evidenced by a Stock Issuance Agreement
("Issuance Agreement") that complies with the terms and conditions of this
Article Three.

           A. CONSIDERATION

              Shares of Common Stock shall be issued under the Plan for one or
more of the following items of consideration, which the Plan Administrator may
deem appropriate in each individual instance:

                (i) cash or cash equivalents (such as a personal check or bank
        draft) paid the Corporation;

                (ii) in Common Stock of the Corporation valued at fair market
        value on the date of issuance;

                (iii) a promissory note payable to the Corporation's order in
        one or more installments, which may be subject to cancellation in whole
        or in part upon terms and conditions established by the Plan
        Administrator;

                (iv) past services rendered to the Corporation or any parent or
        subsidiary corporation;

                (v) any combination of the above approved by the Plan
        Administrator.

              Shares may, in the absolute discretion of the Plan Administrator,
be issued for consideration with a value less than one hundred percent (100%) of
the fair market value of such shares, but in no event less than eighty-five
percent (85%) of such fair market value. Notwithstanding the foregoing, in the
case of 10% stockholders, Shares must be issued at one hundred percent (100%) of
fair market value of such shares.

           B. VESTING PROVISIONS

              1. Shares of Common Stock issued under this Article Three may, in
the absolute discretion of the Plan Administrator, be fully and immediately

                                      -11-
<PAGE>   13
vested upon issuance or may vest in one or more installments over the
Participant's period of Service (as such term is defined in Section I.C.(iii)
of Article Two); provided, that such vesting must be at a rate of at least 20%
per year over no more than five years from the date such shares are issued. The
elements of the vesting schedule applicable to any unvested shares of Common
Stock issued under the Plan, namely:

                   (i) the Service period to be completed by the Participant or
         the performance objectives to be achieved by the Corporation,

                   (ii) the number of installments in which the shares are to
         vest,

                   (iii) the interval or intervals (if any) which are to lapse
         between installments,

                   (iv) any conditions or contingencies to vesting, and

                   (v) the effect which death, disability or other event
         designated by the Plan Administrator is to have upon the vesting
         schedule, shall be determined by the Plan Administrator and
         incorporated into the Issuance Agreement executed by the Corporation
         and the Participant at the time such unvested shares are issued.

                2. The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to him or her under this Article
Three, whether or not his or her interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares. Any new, additional or
different shares of stock or other property (including money paid other than as
a regular cash dividend) which the Participant may have the right to receive
with respect to his or her unvested shares by reason of any stock dividend,
stock split, reclassification of Common Stock or other similar change in the
Corporation's capital structure or by reason of any Corporate Transaction under
Section I of this Article Four shall be issued, subject to (i) the same vesting
requirements applicable to his or her unvested shares and (ii) such escrow
arrangements as the Plan Administrator shall deem appropriate.

                3. Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock under this Article Three,
then those shares shall be immediately surrendered to the Corporation for
cancellation, and the Participant shall have no further stockholder rights with
respect to those shares. The Corporation shall repay to the Participant the cash
consideration paid for the surrendered shares and shall cancel the principal
balance of any outstanding purchase-money note of the Participant to the extent
attributable to such surrendered shares. The surrendered shares may, at the Plan
Administrator's discretion, be retained by the

                                      -12-
<PAGE>   14
Corporation as Treasury Shares or may be retired to authorized but unissued
share status.

                4. The Plan Administrator may in its discretion elect to waive
the surrender and cancellation of one or more unvested shares of Common Stock
(or other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to such shares. Such waiver
shall result in the immediate vesting of the Participant's interest in the
shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

II.     TRANSFER RESTRICTIONS/SHARE ESCROW

        A. Unvested shares under this Article Three may, in the Plan
Administrator's discretion, be held in escrow by the Corporation until the
Participant's interest in such shares vests or may be issued directly to the
Participant with restrictive legends on the certificates evidencing such
unvested shares. To the extent an escrow arrangement is utilized, the unvested
shares and any securities or other assets issued with respect to such shares
(other than regular cash dividends) shall be delivered in escrow to the
Corporation to be held until the Participant's interest in such shares (or other
securities or assets) vests. Alternatively, if the unvested shares are issued
directly to the Participant, the restrictive legend on the certificates for such
shares shall read substantially as follows:

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE UNVESTED AND ARE
        ACCORDINGLY SUBJECT TO (I) CERTAIN TRANSFER RESTRICTIONS AND TO (II)
        CANCELLATION OR REPURCHASE IN THE EVENT THE REGISTERED HOLDER (OR
        HIS/HER PREDECESSOR IN INTEREST) CEASES TO REMAIN IN THE CORPORATION'S
        SERVICE. SUCH TRANSFER RESTRICTIONS AND THE TERMS AND CONDITIONS OF SUCH
        CANCELLATION OR REPURCHASE ARE SET FORTH IN A STOCK ISSUANCE AGREEMENT
        BETWEEN THE CORPORATION AND THE REGISTERED HOLDER (OR HIS/HER
        PREDECESSOR IN INTEREST) DATED ______,19_, A COPY OF WHICH IS ON FILE AT
        THE PRINCIPAL OFFICE OF THE CORPORATION.

        B. The Participant shall have no right to transfer any unvested shares
of Common Stock issued to him or her under this Article Three. For purposes of
this restriction, the term "transfer" shall include (without limitation) any
sale, pledge, assignment, encumbrance, gift, or other disposition of such
shares, whether voluntary or involuntary. Upon any such attempted transfer, the
unvested shares shall immediately be

                                      -13-
<PAGE>   15
cancelled, and neither the Participant nor the proposed transferee shall have
any rights with respect to those shares. However, the Participant shall have the
right to make a gift of unvested shares acquired under the Plan to his or her
spouse or issue, including adopted children, or to a trust established for such
spouse or issue, provided the donee of such shares delivers to the Corporation a
written agreement to be bound by all the provisions of the Plan and the Issuance
Agreement applicable to the gifted shares.

                                  ARTICLE FOUR
                                 MISCELLANEOUS

I.      CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE
        TAKE-OVER

         A. The treatment and rights of optionees or participants in connection
with any Corporate Transaction (as defined below) shall be established in the
option agreement governing such option, which agreement may accelerate vesting
or exercisability, or may provide that the option shall terminate upon any such
transaction.

         B. A Corporate Transaction means:

                (i) a merger or consolidation in which the Corporation is not
     the surviving entity, except for a transaction the principal purpose of
     which is to change the State of the Corporation's incorporation,

                (ii) the sale, transfer or disposition of all or substantially
     all of the assets of the Corporation in liquidation or dissolution of the
     Corporation, or

                (iii) any reverse merger in which the Corporation is the
     surviving entity but in which securities possessing more than fifty percent
     (50%) of the total combined voting power of the Corporation's outstanding
     securities are issued to holders different from those who held such
     securities immediately prior to such merger.

         C. Except as otherwise provided by the Plan Administrator in agreements
governing the grant of options or stock issuances, in connection with any Change
in Control of the Corporation, the exercisability of each option grant at the
time outstanding under this Plan shall automatically accelerate so that each
such option shall, immediately prior to the specified effective date for the
Change in Control, become fully exercisable with respect to the total number of
shares of Common Stock at the time subject to such option and may be exercised
for all or any portion of such shares. Similarly, all unvested shares issued
under the Plan shall automatically vest immediately

                                      -14-
<PAGE>   16
prior to the effective date of the Change in Control. For purposes of this
Article Four, a Change in Control shall be deemed to occur in the event:

                (i) any person or related group of persons (other than the
     Corporation or a person that directly or indirectly controls, is controlled
     by, or is under common control with, the Corporation) directly or
     indirectly acquires beneficial ownership (within the meaning of Rule 13d-3
     of the Securities Exchange Act of 1934, as amended) of securities
     possessing more than fifty percent (50%) of the total combined voting power
     of the Corporation's outstanding securities pursuant to a tender or
     exchange offer made directly to the Corporation's stockholders which the
     Board does not recommend such stockholders to accept; or

                (ii) there is a change in the composition of the Board over a
     period of twenty-four (24) consecutive months or less such that a majority
     of the Board members (rounded up to the next whole number) cease, by reason
     of one or more proxy contests for the election of Board members, to be
     comprised of individuals who either (A) have been Board members
     continuously since the beginning of such period or (B) have been elected or
     nominated for election as Board members during such period by at least a
     majority of the Board members described in clause (A) who were still in
     office at the time such election or nomination was approved by the Board.

The provisions of this Paragraph C shall apply to option grants and/or stock
issuances under the Predecessor Plans only to the extent expressly extended
thereto by the Plan Administrator.

II.      CERTAIN DEFINITIONS

         A. Fair Market Value. The fair market value of a share of Common Stock
shall be determined in accordance with the following provisions:

                - If shares of the Class of Common Stock to be valued are not at
     the time listed or admitted to trading on any national stock exchange but
     is traded on the Nasdaq National Market System, the fair market value shall
     be the closing selling price per share of a share of that class on the date
     in question, as such price is reported by the National Association of
     Securities Dealers through the Nasdaq National Market System or any
     successor system. If there is no reported closing selling price for the
     series on the date in question, then the closing selling price on the last
     preceding date for which such quotation exists shall be determinative of
     fair market value.

                                      -15-
<PAGE>   17
                - If shares of the class of Common Stock to be valued are at the
     time listed or admitted to trading on any national stock exchange, then the
     fair market value of a share of that class shall be the closing selling
     price per share on the date in question on the stock exchange determined by
     the Plan Administrator to be the primary market for the Common Stock, as
     such price is officially quoted in the composite tape of transactions on
     such exchange. If there is no reported sale of a share of the class on such
     exchange on the date in question, then the fair market value shall be the
     closing selling price on the exchange on the last preceding date for which
     such quotation exists.

                - If shares of the series of Common Stock to be valued at the
     time are neither listed nor admitted to trading on any stock exchange nor
     traded on the Nasdaq National Market System, then the fair market value
     shall be determined by the Plan Administrator after taking into account
     such factors as the Plan Administrator shall deem appropriate, which may
     include independent professional appraisals, in a manner consistent with
     the provisions of Section 260.140.50 of the Rules of the California
     Corporations Commissioner.

             B. Hostile Take-Over. A HOSTILE TAKE-OVER shall be deemed to occur
in the event (i) any person or related group of persons (other than the
Corporation or a person that directly or indirectly controls, is controlled by,
or is under common control with, the Corporation) directly or indirectly
acquires beneficial ownership (within the meaning of Rule 13d-3 of the 1934 Act)
of securities possessing more than fifty percent (50%) of the total combined
voting power of the Corporation's outstanding securities pursuant to a tender or
exchange offer made directly to the Corporation's stockholders which the Board
does not recommend such stockholders to accept.

             C. Take-Over Price. The Take-Over Price per share shall be deemed
to be equal to the greater of (a) the fair market value per share on the option
surrender date, as determined pursuant to the valuation provisions of Section
II.A. of this Article Four, or (b) the highest reported price per share paid by
the tender offeror in effecting such Hostile Take-Over.

III.         LOANS OR GUARANTEE OF LOANS

             A. The Plan Administrator may, in its discretion, assist any
Optionee or Participant (including an Optionee or Participant who is an officer
of the Corporation) in the exercise of one or more options granted to such
Optionee under the Article Two Option Grant Program or the purchase of one or
more shares issued to such Participant under the Article Three Stock Issuance
Program, including the satisfaction of any Federal and State income and
employment tax obligations arising therefrom by (i) authorizing the extension of
a loan from the Corporation to such Optionee or Participant or (ii) permitting
the Optionee or Participant to pay the option price or purchase price for the
purchased Common Stock in installments over a period of years.

                                      -16-
<PAGE>   18
The terms of any loan or installment method of payment (including the interest
rate and terms of repayment) will be upon such terms as the Plan Administrator
specifies in the applicable option or issuance agreement or otherwise deems
appropriate under the circumstances. Loans and installment payments may be
granted with or without security or collateral (other than to individuals who
are consultants or independent contractors, in which event the loan must be
adequately secured by collateral other than the purchased shares). However, the
maximum credit available to the Optionee or Participant may not exceed the
option or purchase price of the acquired shares (less the par value of such
shares) plus any Federal and State income and employment tax liability incurred
by the Optionee or Participant in connection with the acquisition of such
shares.

                B. The Plan Administrator may, in its absolute discretion,
determine that one or more loans extended under this financial assistance
program shall be subject to forgiveness by the Corporation in whole or in part
upon such terms and conditions as the Plan Administrator may deem appropriate.

        IV.     TAX WITHHOLDING

                A. The Corporation's obligation to deliver shares or cash upon
the exercise of stock options or stock appreciation rights granted under the
Option Grant Program or upon direct issuance under the Stock Issuance Program
shall be subject to the satisfaction of all applicable Federal, State and local
income and employment tax withholding requirements.

                B. The Plan Administrator may, in its discretion and upon such
terms and conditions as it may deem appropriate, provide any or all holders of
outstanding option grants under the Option Grant Program with the election to
have the Corporation withhold, from the shares of Common Stock otherwise
issuable upon the exercise of such options, a portion of such shares with an
aggregate fair market value equal to the designated percentage (up to 100% as
specified by the optionee) of the Federal and State income taxes ("Taxes")
incurred in connection with the acquisition of such shares. In lieu of such
direct withholding, one or more option holders may also be granted the right to
deliver shares of Common Stock to the Corporation in satisfaction of such Taxes.

        V.      AMENDMENT OF THE PLAN AND AWARDS

                A. Except as herein provided, the Board has complete and
exclusive power and authority to amend or modify the Plan (or any component
thereof) in any or all respects whatsoever. No amendment or modification may
adversely affect the rights and obligations of an Optionee with respect to
options at the time outstanding under the Plan, nor adversely affect the rights
of any Participant with respect to Common Stock issued under the Plan prior to
such action, unless the Optionee or Participant consents to such amendment. In
addition, the Board may, in its discretion, condition any and all such
amendments on the Corporation obtaining approval of its stockholders.

                                      -17-
<PAGE>   19
                B. Options to purchase shares of Common Stock may be granted
under the Option Grant Program and shares of Common Stock may be issued under
the Stock Issuance Program, which are in both instances in excess of the number
of shares then available for issuance under the Plan, provided any excess shares
actually issued under the Option Grant Program or the Stock Issuance Program are
held in escrow until stockholder approval, if required by the Board in
connection with the amendment of the Plan, is obtained for a sufficient increase
in the number of shares available for issuance under the Plan. If such
stockholder approval is required and is not obtained within twelve (12) months
after the date the first such excess option grants or excess share issuances are
made, then (I) any unexercised excess options shall terminate and cease to be
exercisable and (II) the Corporation shall promptly refund the purchase price
paid for any excess shares actually issued under the Plan and held in escrow,
together with interest (at the applicable Short Term Federal Rate) for the
period the shares were held in escrow.

                C. Stockholder approval of this Plan shall not be construed or
interpreted to require that stockholder approval shall be required in connection
with any amendment of this Plan, the adoption by the Corporation of any other
plans, or the grant of options or issuance of shares not covered by any plan.

        VI.     EFFECTIVE DATE AND TERM OF PLAN

                A. This Plan, as successor to the Corporation's Predecessor
Plans, shall become effective as of the Effective Date, and no further option
grants shall be made under the Option Plan nor shall any further shares be
issued under the Stock Plan from and after such Effective Date. If stockholder
approval of this Plan is not obtained within twelve months after the date this
Plan is adopted by the Board, then each option granted under this Plan from and
after the Effective Date shall terminate without ever becoming exercisable for
the option shares and all shares issued hereunder shall be repurchased by the
Corporation at the purchase price paid, together with interest (at the
applicable Short Term Federal Rate). However, in the event such stockholder
approval is not obtained, the Predecessor Plans shall continue in effect in
accordance with the terms and provisions last approved by the Corporation's
stockholders, and all outstanding options and unvested stock issuances under the
Predecessor Plans shall remain in full force and effect in accordance with the
instruments evidencing such options and issuances.

                B. Each outstanding option and share issuance under the
Predecessor Plans immediately prior to the Effective Date of this Plan are
hereby incorporated into this Plan and shall accordingly be treated as an
outstanding option or share issuance under this Plan. However, each such option
or share issuance shall continue to be governed solely by the terms and
conditions of the instrument evidencing such grant or issuance, and except as
otherwise expressly provided in this Plan, no provision of this Plan shall
affect or otherwise modify the rights or obligations of the holders of such
options or shares with respect to their acquisition of shares of Common Stock,
or otherwise modify the rights or obligations of the holders of such options or
shares.

                                      -18-
<PAGE>   20
                C. The sale and remittance procedure authorized for the exercise
of outstanding options under this Plan shall be available for all options
granted under this Plan on or after the Effective Date and for all non-statutory
options outstanding under the Option Plan and incorporated into this Plan. The
Plan Administrator may also allow such procedure to be utilized in connection
with one or more disqualifying dispositions of Incentive Option shares effected
after the Effective Date, whether such Incentive Options were granted under this
Plan or the Option Plan.

                D. The Plan shall terminate upon the earlier of (i) the tenth
anniversary of the Effective Date or (ii) the date on which all shares available
for issuance under the Plan shall have been issued or cancelled pursuant to the
exercise, surrender or cash-out of the options granted under the Option Grant
Program or the issuance of shares (whether vested or unvested) under the Stock
Issuance Program. If the date of termination is determined under clause (i)
above, then all option grants and unvested stock issuances outstanding on such
date shall thereafter continue to have force and effect in accordance with the
provisions of the instruments evidencing such grants or issuances.

        VII.    USE OF PROCEEDS

                Cash proceeds received by the Corporation from the sale of
shares under the Plan shall be used for general corporate purposes.

        VIII.   REGULATORY APPROVALS

                A. The implementation of the Plan, the granting of any option
under the Option Grant Program, the issuance of any shares under the Stock
Issuance Program, and the issuance of Common Stock upon the exercise or
surrender of the option grants made hereunder shall be subject to the
Corporation's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the options granted under it, and
the Common Stock issued pursuant to it.

                B. No shares of Common Stock or other assets shall be issued or
delivered under this Plan unless and until there shall have been compliance with
all applicable requirements of Federal and State securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any securities exchange on which stock of the same class is then listed.

        IX.     NO EMPLOYMENT/SERVICE RIGHTS

                Neither the action of the Corporation in establishing the Plan,
nor any action taken by the Plan Administrator hereunder, nor any provision of
the Plan shall be construed so as to grant any individual the right to remain in
the employ or service of the Corporation (or any parent or subsidiary
corporation) for any period of specific

                                      -19-
<PAGE>   21
duration, and the Corporation (or any parent or subsidiary corporation retaining
the services of such individual) may terminate such individual's employment or
service at any time and for any reason, with or without cause.

X.      MISCELLANEOUS PROVISIONS

        A. The right to acquire Common Stock or other assets under the Plan
may not be assigned, encumbered or otherwise transferred by any Optionee or
Participant.

        B. The provisions of the Plan shall inure to the benefit of, and be
binding upon, the Corporation and its successors or assigns, whether by
Corporate Transaction or otherwise, and the Participants and Optionees, the
legal representatives of their respective estates, their respective heirs or
legatees and their permitted assignees.

                   INTERACT MEDICAL TECHNOLOGIES CORPORATION

                             STOCK OPTION AGREEMENT

                                  WITNESSETH:

RECITALS

         A. INTERACT MEDICAL TECHNOLOGIES CORPORATION (the "Company") has
adopted the 1996 Stock Option/Stock Issuance Plan (the "Plan") for the purpose
of attracting and retaining the services of selected key employees (including
officers and directors) and consultants and other independent contractors who
contribute to the financial success of the Company or its parent or subsidiary
corporations.

         B. Optionee is an individual who is to render valuable services to the
Company or its parent or subsidiary corporations, and this Agreement is executed
pursuant to, and is intended to carry out the purposes of, the Plan in
connection with the Company's grant of a stock option to Optionee.

         NOW, THEREFORE, it is hereby agreed as follows:

                1. GRANT OF OPTION. Subject to and upon the terms and conditions
set forth in this Agreement, the Company hereby grants to Optionee, as of the
grant date (the "Grant Date") specified in the accompanying Notice of Grant of
Stock Option (the "Notice of Grant"), a stock option to purchase up to that
number of shares of the Company's Common Stock (the "Option Shares") as is
specified in the Notice of Grant. The Option Shares shall be purchasable from
time to time during the option term at the option price per share (the "Option
Price") specified in the Notice of Grant.

                2. OPTION TERM. This option shall have a maximum term of ten
(10) years measured from the Grant Date and shall accordingly expire at the
close of business on the expiration date (the "Expiration Date") specified in
the Notice of Grant, unless sooner terminated in accordance with Paragraph 5 or
6.

                3. LIMITED TRANSFERABILITY. This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following the Optionee's death and may be exercised,
during Optionee's lifetime, only by Optionee, unless such assignment or transfer
is expressly approved by the Plan Administrator.

                4. EXERCISABILITY. This option shall become exercisable for the
Option Shares in one or more installments as specified in the Notice of Grant.
As the option becomes exercisable for the Option Shares in one or more such
installments, those
<PAGE>   3
installments shall accumulate and the option shall remain exercisable for the
accumulated installments until the Expiration Date or the sooner termination of
the option term under Paragraph 5 or 6 of this Agreement.

                5. TERMINATION OF SERVICE. The option term specified in
Paragraph 2 shall terminate (and this option shall cease to be exercisable)
prior to the Expiration Date should one of the following provisions become
applicable:

                      (i) Except to the extent otherwise provided in
      subparagraphs (ii) and (iii) below, should Optionee cease to remain in the
      Service of the Company at any time during the option term, then this
      option shall not remain exercisable for more than a ninety (90)-day period
      commencing with the date of such cessation of Service. Upon the expiration
      of such ninety (90)-day period or (if earlier) upon the specified
      Expiration Date of the option term, this option shall terminate and cease
      to be outstanding.

                      (ii) Should Optionee die while in Service or within the
      ninety (90)-day period following his or her cessation of Service, then the
      personal representative of the Optionee's estate or the person or persons
      to whom this option is transferred pursuant to the Optionee's will or in
      accordance with the law of descent and distribution shall have the right
      to exercise this option. Such right shall lapse, and this option shall
      terminate and cease to remain exercisable, upon the earlier of (A) the
      expiration of the twelve (12)-month period measured from the date of
      Optionee's death or (B) the Expiration Date.

                      (iii) Should Optionee become permanently disabled and
      cease by reason thereof to remain in Service at any time during the option
      term, then this option shall not remain exercisable for more than a twelve
      (12) month period commencing with the date of such cessation of Service.
      Upon the expiration of such limited period of exercisability or (if
      earlier) upon the Expiration Date, this option shall terminate and cease
      to be outstanding.

                      (iv) In no event shall this option be exercisable at any
      time after the specified Expiration Date of the option term.

                      (v) During the limited post-Service period of
      exercisability determined in accordance with subparagraphs (i) through
      (iii) above, this option may not be exercised for more than the number of
      Option Shares (if any) for which this option is, at the time of the
      Optionee's cessation of Service, exercisable in accordance with either the

                                      -2-
<PAGE>   4
      normal exercise provisions specified in the Notice of Grant or the special
      acceleration provisions of Paragraph 6 of this Agreement. However, the
      number of Option Shares purchasable after the Optionee's death shall be
      reduced for any Option Shares purchased by the Optionee after his or her
      cessation of Service but prior to death.

                (vi) For purposes of this Paragraph 5 and for all other
      purposes under this Agreement, the following definitional provisions shall
      be in effect:

                     A. The Optionee shall be deemed to remain in SERVICE for so
      long as the Optionee continues to render periodic services to the Company
      or any parent or subsidiary corporation, whether as an Employee, a
      non-employee member of the Company's Board of Directors or an independent
      consultant or advisor.

                     B. The Optionee shall be deemed to be an EMPLOYEE and to
      continue in the Company's employ for so long as the Optionee remains in
      the employ of the Company or one or more of its parent or subsidiary
      corporations, subject to the control and direction of the employer entity
      as to both the work to be performed and the manner and method of
      performance.

                     C. The Optionee shall be deemed to be PERMANENTLY DISABLED
      if the Optionee is, by reason of any medically determinable physical or
      mental impairment expected to result in death or to be of continuous
      duration of not less than twelve (12) consecutive months or more, unable
      to perform his or her usual duties for the Company or the parent or
      subsidiary corporation retaining his or her services.

                     D. A corporation shall be considered to be a SUBSIDIARY
      corporation of the Company if it is a member of an unbroken chain of
      corporations beginning with the Company, provided each such corporation in
      the chain (other than the last corporation) owns, at the time of
      determination, stock possessing 50% or more of the total combined voting
      power of all classes of stock in one of the other corporations in such
      chain.

                     E. A corporation shall be considered to be a PARENT
      corporation of the Company if it is a member of an unbroken chain ending
      with the Company, provided each such corporation in the chain (other than
      the Company) owns, at the tie of determination, stock

                                      -3-
<PAGE>   5
      possessing 50% or more of the total combined voting power of all classes 
      of stock in one of the other corporations in such chain.

      6. CORPORATE TRANSACTION.

         A. For purposes of this paragraph, a "Corporate Transaction" shall be
one or more of the following stockholder-approved transactions:

                     (i) a merger or consolidation in which the Company is not
      the surviving entity, except for a transaction the principal purpose of
      which is to change the State of the Company's incorporation,

                     (ii) the sale, transfer or other disposition of all or
      substantially all of the assets of the Company in liquidation or
      dissolution of the Company, or

                     (iii) any reverse merger in which the Company is the
      surviving entity but in which securities possessing more than fifty
      percent (50%) of the total combined voting power of the Company's
      outstanding securities are issued to holders different from those who held
      such securities immediately prior to such merger.

         B. If this option is to be assumed in connection with the Corporate
Transaction or is otherwise to continue in effect, then it shall be
appropriately adjusted, immediately after such Corporate Transaction, to apply
and pertain to the number and class of securities which would have been
issuable, in consummation of such Corporate Transaction, to an actual holder of
the same number of shares of Common Stock as are subject to such option
immediately prior to such Corporate Transaction. Appropriate adjustments shall
also be made to the option price payable per share, provided that the aggregate
option price payable for such securities shall remain the same.

         C. Except to the extent that any option is to be assumed by the
acquiring or successor corporation in a Corporate Transaction (as herein
defined), each option outstanding hereunder shall expire and terminate
immediately prior to the consummation of such Corporate Transaction.

         D. The exercisability of this option as an incentive stock option under
the Federal tax laws (if designated as such in the Notice of Grant) shall, in
connection with any such Corporate Transaction, be subject to the applicable
dollar limitation of Paragraph 18.

         E. This Agreement shall not in any way affect the right of the Company
to adjust, reclassify, reorganize or otherwise make changes in its capital or

                                      -4-
<PAGE>   6
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         7. ADJUSTMENT IN OPTION SHARES.

            A. In the event any change is made to the Common Stock issuable
under the Plan by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares, or other change affecting the
outstanding Common Stock as a class without the Company's receipt of
consideration, then appropriate adjustments shall be made to (i) the total
number of Option Shares subject to this option and (ii) the Option Price payable
per share in order to reflect such change and thereby preclude a dilution or
enlargement of benefits hereunder.

            B. If this option is to be assumed in connection with a Corporate
Transaction or is otherwise to continue in effect, then this option shall,
immediately after such Corporate Transaction, be appropriately adjusted to apply
and pertain to the number and class of securities which would have been issued
to the Optionee in the consummation of such Corporate Transaction had the option
been exercised immediately prior to such Corporate Transaction. Appropriate
adjustments shall also be made to the Option Price payable per share, provided
the aggregate Option Price payable hereunder shall remain the same.

         8. PRIVILEGE OF STOCK OWNERSHIP. The holder of this option shall not
have any of the rights of a stockholder with respect to the Option Shares until
such individual shall have exercised the option, paid the Option Price for the
purchased shares and been issued a stock certificate for such shares.

         9. MANNER OF EXERCISING OPTION.

            A. In order to exercise this option with respect to all or any part
of the Option Shares for which this option is at the time exercisable, Optionee
(or in the case of exercise after Optionee's death, the Optionee's executor,
administrator, heir or legatee, as the case may be) must take the following
actions:

                     (i) Execute and deliver to the Secretary of the Company a
      written notice of exercise (the "Exercise Notice"), in substantially the
      form of Exhibit I attached hereto, in which there is specified the number
      of Option Shares for which the option is exercised.

                     (ii) Pay the aggregate Option Price for the purchased
      shares in one or more of the following alternative forms:

                                      -5-
<PAGE>   7
                1. full payment in cash or check drawn to the Company's order;

                2. full payment in shares of Common Stock of the Company held by
      the Optionee for at least six (6) months and valued at Fair Market Value
      on the Exercise Date (as such terms are defined below);

                3. full payment in a combination of shares of Common Stock of
      the Company held by the Optionee for at least six (6) months and valued at
      Fair Market Value on the Exercise Date, and cash or check drawn to the
      Company's order;

                4. full payment effected through a broker-dealer sale and
      remittance procedure pursuant to which the Optionee (I) shall provide
      irrevocable written instructions to a designated brokerage firm to effect
      the immediate sale of the purchased shares and remit to the Company, out
      of the sale proceeds available on the settlement date, sufficient funds to
      cover the aggregate Option Price payable for the purchased shares plus all
      applicable Federal and State income and employment taxes required to be
      withheld by the Company by reason of such purchase and (II) shall provide
      written directives to the Company to deliver the certificates for the
      purchased shares directly to such brokerage firm in order to complete the
      sale transaction; or

                5. full payment in any other form which the Plan Administrator
      may, in its discretion, approve at the time of exercise in accordance with
      the provisions of Paragraph 15 of this Agreement.(1)

                (iii) Furnish to the Company appropriate documentation that the
      person or persons exercising the option (if other than the Optionee) have
      the right to exercise this option.

         B. For purposes of this Agreement, the Fair Market Value of a share of
Common Stock on any relevant date shall be determined in accordance with
subparagraphs (i) and (ii) below, and the Exercise Date shall be the date on
which the executed Exercise Notice is delivered to the Company. Except to the
extent the sale and remittance procedure specified above is utilized for the
exercise of the option, payment

- - ------------------
(1) Authorization of a Company loan or installment payment pursuant to this
provision may, under currently proposed Treasury Regulations, result in the loss
of incentive stock option treatment under the Federal tax laws.

                                      -6-
<PAGE>   8
of the Option Price for the purchased shares must accompany the Exercise Notice.
The procedure for measuring Fair Market Value shall be as follows:

                (i) If the Common Stock is not at the time listed or admitted to
      trading on any national stock exchange but is traded on the Nasdaq
      National Market System, Fair Market Value shall be the closing selling
      price per share of Common Stock on the date in question, as such price is
      reported by the National Association of Securities Dealers through the
      Nasdaq National Market System or any successor system. If there is no
      reported closing selling price for the Common Stock on the date in
      question, then the closing selling price on the last preceding date for
      which such quotation exists shall be determinative of Fair Market Value.

                (ii) If the Common Stock is at the time listed or admitted to
      trading on any national stock exchange, then the Fair Market Value shall
      be the closing selling price per share of Common Stock on the date in
      question on the stock exchange determined by the Plan Administrator to be
      the primary market for the Common Stock, as such price is officially
      quoted in the composite tape of transactions on such exchange. If there is
      no reported sale of Common Stock on such exchange on the date in question,
      then the Fair Market Value shall be the closing selling price on the
      exchange on the last preceding date for which such quotation exists.

                (iii) If shares of the series of Common Stock to be valued at
      the time are neither listed nor admitted to trading on any stock exchange
      nor traded in the over-the-counter market, then the fair market value
      shall be determined by the Plan Administrator after taking into account
      such factors as the Plan Administrator shall deem appropriate, including
      one or more independent professional appraisals.

        C. As soon after the Exercise Date as practical, the Company shall mail
or deliver to or on behalf of the Optionee (or to any other person or persons
exercising this option) a certificate or certificates representing the purchased
shares.

        D. In no event may this option be exercised for any fractional shares.

    10. COMPLIANCE WITH LAWS AND REGULATIONS.

        A. The exercise of this option and the issuance of the Option Shares
upon such exercise shall be subject to compliance by the Company and the
Optionee with all applicable requirements of law relating thereto and with all
applicable

                                      -7-
<PAGE>   9
regulations of any stock exchange on which shares of the Option Shares may be
listed at the time of such exercise and issuance.

             B. In connection with the exercise of this option, Optionee shall
execute and deliver to the Company such representations in writing as may be
requested by the Company in order for it to comply with the applicable
requirements of federal and state securities laws.

         11. SUCCESSORS AND ASSIGNS. Except to the extent otherwise provided in
Paragraph 3 or 6, the provisions of this Agreement shall inure to the benefit
of, and be binding upon, the successors, administrators, heirs, legal
representatives and assigns of Optionee and the successors and assigns of the
Company.

         12. LIABILITY OF COMPANY.

             A. If the Option Shares covered by this Agreement exceed, as of the
Grant Date, the number of shares of Common Stock which may without stockholder
approval be issued under the Plan, then this option shall be void with respect
to such excess shares, unless stockholder approval of an amendment sufficiently
increasing the number of shares of Common Stock issuable under the Plan is
obtained in accordance with the provisions of Article 4, Section III of the
Plan.

             B. The inability of the Company to obtain approval from any
regulatory body having authority deemed by the Company to be necessary to the
lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Company of any liability with respect to the non-issuance or sale of
the Common Stock as to which such approval shall not have been obtained. The
Company, however, shall use its best efforts to obtain all such approvals.

         13. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or in
the Plan shall confer upon the Optionee any right to continue in the Service of
the Company (or any parent or subsidiary corporation of the Company employing or
retaining Optionee) for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Company (or any parent or
subsidiary corporation of the Company employing or retaining Optionee) or the
Optionee, which rights are hereby expressly reserved by each, to terminate the
Optionee's Service at any time for any reason whatsoever, with or without cause.

         14. NOTICES. Any notice required to be given or delivered to the
Company under the terms of this Agreement shall be in writing and addressed to
the Company in care of the Corporate Secretary at the Company's principal
corporate offices. Any notice required to be given or delivered to Optionee
shall be in writing and addressed to Optionee at the address indicated below
Optionee's signature line on the Notice of

                                      -8-
<PAGE>   10
Grant. All notices shall be deemed to have been given or delivered upon personal
delivery or upon deposit in the U.S. mail, postage prepaid and properly 
addressed to the party to be notified.

         15. LOANS. The Plan Administrator may, in its absolute discretion and
without any obligation to do so, assist the Optionee in the exercise of this
option by (i) authorizing the extension of a loan to the Optionee from the
Company or (ii) permitting the Optionee to pay the Option Price for the
purchased Common Stock in installments over a period of years. The terms of any
loan or installment method of payment (including the interest rate, the
collateral requirements and terms of repayment) shall be established by the Plan
Administrator in its sole discretion.

         16. CONSTRUCTION. This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the express terms and provisions of the Plan. All decisions of the
Plan Administrator with respect to any question or issue arising under the Plan
or this Agreement shall be conclusive and binding on all persons having an
interest in this option.

         17. GOVERNING LAW. The interpretation, performance, and enforcement of
this Agreement shall be governed by the laws of the State of California without
resort to that State's conflict-of-laws rules.

         18. ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE STOCK OPTION. In the
event this option is designated as an incentive stock option in the Notice of
Grant, the following terms and conditions shall also apply to the grant:

             A. This option shall cease to qualify for favorable tax treatment
as an incentive stock option under the Federal tax laws if (and to the extent)
this option is exercised for one or more Option Shares: (i) more than three (3)
months after the date the Optionee ceases to be an Employee for any reason other
than death or permanent disability (as defined in Paragraph 5) or (ii) more than
one (1) year alter the date the Optionee ceases to be an Employee by reason of
permanent disability.

             B. No installment under this option (whether annual or monthly)
shall qualify for favorable tax treatment as an incentive stock option under the
Federal tax laws if (and to the extent) the aggregate fair market value
(determined at the Grant Date) of the Common Stock for which such installment
first becomes exercisable hereunder will, when added to the aggregate fair
market value (determined as of the respective date or dates of grant) of any
earlier installments of Common Stock for which this option or any other
post-1986 incentive stock options granted to the Optionee prior to the Grant
Date (whether under the Plan or any other option plan of the Company or any
parent or subsidiary corporations) first become exercisable during the same
calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate.

                                      -9-
<PAGE>   11
             C. Should the exercisability of this option be accelerated upon a
Corporate Transaction, then this option shall qualify for favorable tax
treatment as an incentive stock option under the Federal tax laws only to the
extent the aggregate fair market value (determined at the Grant Date) of the
Common Stock for which this option first becomes exercisable at the time the
Corporate Transaction occurs does not, when added to the aggregate fair market
value (determined as of the respective date or dates of grant) of any earlier
installments of Common Stock for which this option or any other post-1986
incentive stock options granted to the Optionee prior to the Grant Date (whether
under the Plan or any other option plan of the Company or any parent or
subsidiary corporations) first become exercisable during the calendar year in
which the Corporate Transaction occurs, exceed One Hundred Thousand Dollars
($100,000) in the aggregate.

             D. To the extent this option should fall to qualify as an incentive
stock option under the Federal tax laws, the Optionee will recognize
compensation income in connection with the acquisition of one or more Option
Shares hereunder, and the Optionee must make appropriate arrangements for the
satisfaction of all Federal, State or local income tax withholding requirements
and Federal social security employee tax requirements applicable to such
compensation income.

             E. The Plan Administrator shall not consent to any assignment or
transfer not otherwise permitted hereunder.

         19. ADDITIONAL TERMS APPLICABLE TO A NON-STATUTORY STOCK OPTION. In the
event this option is designated as a non-statutory stock option in the Notice of
Grant, Optionee hereby agrees to make appropriate arrangements with the Company
or parent or subsidiary corporation employing Optionee for the satisfaction of
any Federal, State or local income tax withholding requirements and Federal
social security employee tax requirements applicable to the exercise of this
option.

        of payroll deduction. Such reduction shall become effective as soon as
        possible after filing of the requisite reduction form with the Plan
        Administrator (or its designate), but the Participant may not effect
        more than one such reduction during the same Quarter.

           - The Participant may, prior to the commencement of any new Quarter
        within the option period, increase or decrease the rate of payroll
        deduction for the new Quarter by filing the appropriate form with the
        Plan Administrator (or its designate). The new rate shall become
        effective as of the first day of the next Quarter.

           Payroll deductions will automatically cease upon the termination
of the Participant's purchase right in accordance with the applicable provisions
of Section VII below.

VI.     STOCK SUBJECT TO PLAN

        A The maximum number of shares of Common Stock which may be issued under
the Plan shall be 200,000 shares of Common Stock (subject to adjustment under
Section VI.B. below).

                                      -4-
<PAGE>   6
        B. In the event any change is made to the Company's outstanding Common
Stock by reason of any stock dividend, stock split, combination of shares or
other change affecting such outstanding Common Stock as a class without receipt
of consideration, then appropriate adjustments shall be made by the Plan
Administrator to (i) the class and maximum number of shares issuable over the
term of the Plan, (ii) the class and maximum number of shares purchasable per
Participant during any one option period and (iii) the class and number of
shares and the price per share in effect under each purchase right at the time
outstanding under the Plan. Such adjustments shall be designed to preclude the
dilution or enlargement of rights and benefits under the Plan.

VII.    PURCHASE RIGHTS

        Each Participant in a particular option period shall have the right to
purchase shares of Common Stock in a series of successive quarterly installments
during such option period on the terms and conditions set forth below (the
"Purchase Rights"). Each Participant shall execute a purchase agreement
embodying such terms and conditions and such other provisions (not inconsistent
with the Plan) as the Plan Administrator may require.

        Purchase Price. The Purchase Rights shall be exercised at the end of
each Quarter at a purchase price equal to eighty-five percent (85%) of the lower
of (i) the fair market value per share of the Common Stock on the Participant's
Entry Date or (ii) the fair market value per share of the Common Stock on the
last business day of the Quarter. However, for each Participant whose Entry Date
is other than the first day of the option period, the amount determined under
clause (i) shall not be less than the fair market value of the Common Stock on
the first day of such option period.

        Valuation. For purposes of determining the fair market value per share
of Common Stock on any relevant date, the following procedures shall be in
effect:

        - If fair market value is to be determined on or after the date the
        Common Stock is first registered under Section 12(g) of the Securities
        Exchange Act of 1934, as amended, then the fair market value shall be
        the closing selling price on that date, as officially quoted on the
        Nasdaq National Market System, or if there is no quoted selling price
        for such date, then the closing selling price on the next preceding day
        for which there does exist such a quotation.

        - If fair market value is to be determined prior to such Section 12(g)
        registration of the Common Stock, then the fair market value of the
        Common Stock on such date shall be determined by the Plan Administrator
        after taking into account such factors as the Plan Administrator deems
        appropriate.

                                      -5-
<PAGE>   7
         Number of Purchasable Shares. The number of shares purchasable by a
Participant each Quarter shall be the number of whole shares obtained by
dividing the amount in Participant's Account at the end of such Quarter by the
purchase price in effect for the Quarter.

         Notwithstanding the above, (i) no Participant shall have the right to
purchase more than 2,500 shares of Common Stock in any one Option Period, and
(ii) no Participant shall have the right to purchase shares of Common Stock to
the extent that, immediately after the grant, such Participant would own (within
the meaning of Code Section 424(d)) or hold outstanding options or other rights
to purchase, stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of stock of the Company or any of its
Corporate Affiliates.

         Payment. Payment for the Common Stock purchased under the Plan shall be
effected by means of the Participant's authorized payroll deductions. Such
deductions shall begin on the first pay day coincident with or immediately
following the Participant's Entry Date into the option period and shall (unless
sooner terminated by the Participant) continue through the pay day ending with
or immediately prior to the last day of the option period. The amounts so
collected shall be credited to the Participant's Account under the Plan, but no
interest shall be paid on the balance from time to time outstanding in such
Account. The amounts collected from a Participant may be commingled with the
general assets of the Company and may be used for general corporate purposes.

         Termination of Purchase Right. The following provisions shall govern
the termination of outstanding purchase rights:

                (i) A Participant may, at any time prior to the last five (5)
      business days of the Quarter, terminate his/her outstanding purchase right
      under the Plan by filing the prescribed notification form with the Plan
      Administrator (or its designate). No further payroll deductions shall be
      collected from the Participant with respect to the terminated purchase
      right, and any payroll deductions collected for the current Quarter shall,
      at the Participant's election, be immediately refunded or held for the
      purchase of shares on the end of the Quarter. If no such election is made,
      then such funds shall be refunded as soon as possible after the close of
      such Quarter.

                (ii) After the termination of purchase rights for an option
      period, the Participant may not subsequently rejoin that option period. In
      order to resume participation in any subsequent option period, such
      individual must re-enroll in the Plan for that option period.

                (iii) If a Participant ceases to be a Qualifying Employee for
      any reason whatsoever during an option period then all payroll

                                      -6-
<PAGE>   8
      deductions shall terminate and all funds held in the Participant's Account
      will be promptly paid to the Participant or the Participant's legal
      representative. No further purchases of shares hereunder shall occur after
      the Participant has ceased to be a Qualifying Employee.

         Stock Purchase. Subject to the limitations set forth herein, funds held
in a Participant's Account at the end of a Quarter (and which are not required
to be refunded hereunder) shall be applied to the purchase of whole shares of
Common Stock for the Participant on the last business day of the Quarter at the
purchase price in effect for such Quarter. Any payroll deductions not applied to
such purchase because they are not sufficient to purchase a whole share shall be
held for the purchase of Common Stock in the next Quarter. Any payroll
deductions not applied to the purchase of Common Stock for any other reason
shall be promptly refunded to the Participant.

         Proration of Purchase Rights. If the total number of shares of Common
Stock which would otherwise be purchased hereunder on any date exceed the number
of shares then available for issuance under the Plan, the Plan Administrator
shall make a pro-rata allocation of the available shares to Participants on a
uniform and nondiscriminatory basis.

         Rights as Stockholder. A Participant shall have no stockholder rights
with respect to the shares subject to his/her outstanding purchase right until
the shares are actually purchased on the Participant's behalf in accordance with
the applicable provisions of the Plan. No adjustments shall be made for
dividends, distributions or other rights for which the record date is prior to
the date of such purchase.

         A Participant shall be entitled to receive, as soon as practicable
after purchase hereunder, a stock certificate for the number of shares purchased
for the Participant. Such certificate may, upon the Participant's request, be
issued in the names of the Participant and his/her spouse as community property
or as joint tenants with right of survivorship.

         Assignability. No purchase right granted under the Plan shall be
assignable or transferable by the Participant other than by will or by the laws
of descent and distribution following the Participant's death, and during the
Participant's lifetime the purchase right shall be exercisable only by the
Participant.

         Change in Ownership. Should the Company or its stockholders enter into
an agreement to dispose of all or substantially all of the assets or outstanding
capital stock of the Company by means of:

                (i) a sale, merger or other reorganization in which the Company
      will not be the surviving corporation (other than a reorganization
      effected primarily to change the State in which the Company is
      incorporated), or

                                      -7-
<PAGE>   9
                (ii) a reverse merger in which the Company is the surviving
      corporation but in which more than 50% of the Company's outstanding voting
      stock is transferred to holders different from those who held the stock
      immediately prior to the reverse merger,

        then all outstanding purchase rights under the Plan shall automatically
be exercised immediately prior to the consummation of such sale, merger,
reorganization or reverse merger by applying the amounts in each Participant's
Account to the purchase of whole shares of Common Stock at eighty-five percent
(85%) of the lower of (i) the fair market value of the Common Stock on the
Participant's Entry Date into the option period in which such transaction occurs
or (ii) the fair market value of the Common Stock immediately prior to the
consummation of such transaction. However, the applicable share limitations of
Articles VII and VIII shall continue to apply to any such purchase, and the
clause (i) amount above shall not, for any Participant whose Entry Date for the
option period is other than the start date of such option period, be less than
the fair market value of the Common Stock on such start date.

        The Company shall use its best efforts to provide at least ten (10)-days
advance written notice of the occurrence of any such sale, merger,
reorganization or reverse merger, and Participants shall, following the receipt
of such notice, have the right to terminate their outstanding purchase rights in
accordance with the applicable provisions of this Article VII.

VIII.   ACCRUAL LIMITATIONS

        A. No Participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right outstanding under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Section 423 of the Code) of the Company or its Corporate Affiliates,
would otherwise permit such Participant to purchase more than $25,000 worth of
stock of the Company or any Corporate Affiliate (determined on the basis of the
fair market value of such stock on the date or dates such rights are granted to
the Participant) for each calendar year such rights are at any time outstanding.

        B. For purposes of applying such accrual limitations, the right to
acquire Common Stock pursuant to each purchase right outstanding under the Plan
shall accrue as follows:

                (i) The right to acquire Common Stock under each such purchase
      right shall accrue in a series of successive quarterly installments as and
      when the purchase right first becomes exercisable for each quarterly

                                      -8-
<PAGE>   10
      installment on the last business day of each Quarter for which the right 
      remains outstanding.

                (ii) No right to acquire Common Stock under any outstanding
      purchase right shall accrue to the extent the Participant has already
      accrued in the same calendar year the right to acquire $25,000 worth of
      Common Stock (determined on the basis of the fair market value on the date
      or dates of grant) pursuant to one or more purchase rights held by the
      Participant during such calendar year.

                (iii) If by reason of such accrual limitations, any purchase
      right of a Participant does not accrue for a particular Quarter, then the
      payroll deductions which the Participant made during that Quarter with
      respect to such purchase right shall be promptly refunded.

                C. In the event there is any conflict between the provisions of
this Article VIII and one or more provisions of the Plan or any instrument
issued thereunder, the provisions of this Article VIII shall be controlling.

IX.     STATUS OF PLAN UNDER FEDERAL TAX LAWS

        The Plan is designed to qualify as an employee stock purchase plan under
Code Section 423.

X.      AMENDMENT AND TERMINATION

        A. The Board may alter, amend, suspend or discontinue the Plan following
the close of any Quarter. However, the Board may, if it so determines, condition
any amendment on the Company having obtained the approval of the Company's
stockholders.

        B. The Company shall have the right, exercisable in the sole discretion
of the Plan Administrator, to terminate all outstanding purchase rights under
the Plan immediately following the close of any Quarter. Should the Company
elect to exercise such right, then the Plan shall terminate in its entirety. No
further purchase rights shall thereafter be granted or exercised, and no further
payroll deductions shall thereafter be collected, under the Plan.

XI.     GENERAL PROVISIONS

        A. The term of this Plan shall commence on the effective date of the S-8
Registration Statement covering the Common Stock issuable under the Plan,
provided that the term shall not commence, and no shares of Common Stock shall
be issued hereunder, until (i) the Plan shall have been approved by the
stockholders; (ii) the Company shall have

                                      -9-
<PAGE>   11
complied with all applicable requirements, all applicable listing requirements
of any securities exchange on which shares of the Common Stock are listed and
all other applicable requirements established by law or regulation and the Plan
Administrator shall have determined to commence granting Purchase Rights
hereunder. In the event stockholder approval is not obtained, or Company
compliance with the Act is not effected, within twelve (12) months after the
date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect.

                B. The Plan shall terminate on June 3, 2006.

                C. All costs and expenses incurred in the administration of the
Plan shall be paid by the Company.

                D. Neither the action of the Company in establishing the Plan,
nor any action taken under the Plan by the Board or the Plan Administrator, nor
any provision of the Plan itself shall be construed so as to grant any person
the right to remain in the employ of the Company or any Corporate Affiliate for
any period, and such person's employment may be terminated at any time, with or
without cause.

                   INTERACT MEDICAL TECHNOLOGIES CORPORATION
                       1996 EMPLOYEE STOCK PURCHASE PLAN
                            STOCK PURCHASE AGREEMENT

1.  I hereby elect to participate In the Interact Medical Technologies
    Corporation 1996 Employee Stock Purchase Plan (the "Plan") for the option
    period specified below, and I accordingly subscribe to purchase shares of
    Interact Medical Technologies Corporation Common Stock at the end of each of
    my quarterly periods of participation within such option period.

2.  By separate form, I have authorized payroll deductions from each of my
    paychecks during my period of participation in the option period. Such
    payroll deductions will be accumulated for the purchase of shares of
    Interact MEDICAL Technologies Corporation Common Stock on the last business
    day of each quarterly period of participation. The purchase price per share
    will be the lower of (i) 85% of the market price on the start date of the
    quarterly period of participation in which I first enter the option period
    or (ii) 85% of the market price on each quarterly purchase date. However,
    the clause (i) amount will in no event be less than 85% of the market price
    on the start date of the option period.

3.  This enrollment will be effective for the duration of the option period
    specified below, and shares will automatically be purchased on my behalf at
    the end of each quarterly period of participation, unless I withdraw from
    the Plan or my employment terminates.

4.  My rate of payroll deduction will automatically continue in effect for each
    of my quarterly periods of participation within the option period, unless I
    change such rate or otherwise withdraw from the Plan or my employment
    terminates.

5.  I can withdraw from the Plan at any time and elect either to have the
    Company refund all my payroll deductions for the quarterly period of
    participation in which I withdraw or to have such payroll deductions applied
    to the purchase of Interact Medical Technologies Corporation Common Stock at
    the end of such period. However, I may not rejoin the Plan for that
    particular option period at any later date. Upon my termination of
    employment or change to ineligible employee status, payroll deductions will
    automatically cease on my behalf and the Company will refund my payroll
    deductions to date in the quarterly period of participation in which such
    termination or change occurs.

6.  I have a copy of, and am familiar with, the official Plan Prospectus
    summarizing the operation of the Plan. A complete copy of the actual plan
    document is attached as Exhibit A to the Prospectus.

7.  I am to receive a stock certificate for the shares purchased on my behalf
    after each quarterly purchase date. The certificate will be issued as
    indicated on my Enrollment/Change Form.

8.  The Company has the right to amend or terminate the Plan at any time, with
    such amendment or termination to become effective immediately following the
    exercise of outstanding purchase rights at the end of any current quarterly
    period of participation. Should the Company elect to terminate the Plan, I
    will have no further rights to purchase shares of Interact Medical
    Technologies Corporation Common Stock pursuant to this Agreement.

9.  I am familiar with the Plan restriction prohibiting any participant from
    purchasing more than $25,000 worth of Common Stock per calendar year.

10. I have read this Agreement and the Plan. I hereby agree to be bound by the
    terms of both this Agreement and the Plan. The effectiveness of this
    Agreement is dependent upon my eligibility to participate in the Plan.

            Ixion Employee Non-Disclosure and Non-Compete Agreement

                                    GENERAL

As an employee of Ixion (a Delaware corporation), I will devote my best efforts
to furthering the Business purposes and interests of Ixion. As defined herein,
Ixion "Business" will be the development, marketing, and support of medical
simulation systems along with other such business as is called out in an Ixion
Mission Statement, which Ixion will update quarterly or more frequently, and
which will be supplied to me when updated.

During my employment I will not engage in any non-Ixion activity or investment
outside of Ixion that (a) conflicts with Ixion's Business purposes or
interests, including without limitation any additional interests as described
in the Ixion Mission Statement, (b) occupies my attention so as to interfere
with the proper and efficient performance of my duties at Ixion, or (c)
interferes with the independent exercise of my judgment in Ixion's best 
interests.

                                NON-DISCLOSURE

At all times during my employment and thereafter I will not disclose to anyone
outside Ixion nor use for the purpose other than my work for Ixion (a) any
confidential, client-proprietary, technical, financial, marketing,
manufacturing, distribution or other technical or business information or trade
secrets of Ixion, including without limitation, business plans or proposals,
sales and pricing information, information about business relationships with
customers or suppliers, vendors, or contracts, customer lists, concepts,
techniques, processes, methods systems, designs, circuits, cost data, computer
program, formulas, development or experimental work, work in progress,
customers and suppliers, (b) any information Ixion has received from others
which Ixion is obligated to treat as confidential or proprietary or (c) any
confidential or proprietary information which is circulated within Ixion.
Furthermore, I will not remove such proprietary materials as described in (a),
(b), or (c) above from the premises of Ixion without permission of Ixion.

                                INVENTIONS

I will make prompt and full disclosure to Ixion, will hold in trust for the
sole benefit of Ixion, and will assign exclusively to Ixion all my right and
title, and interest in and all Inventions including discoveries, designs,
developments, improvements, copyrightable material, trade secrets, and patents
(herein collectively named "Inventions") that I solely or jointly, may
conceive, develop, or reduce to practice as a result of or in connection with
services performed for Ixion. All material developed for Ixion shall be
considered "work-for-hire."

I hereby waive and quitclaim to Ixion any and all claims of any nature
whatsoever that I now or hereafter may have for infringement of any patent
resulting from any patent applications for any Inventions assigned to Ixion. I
further understand that key contributors will be named in Ixion patents at the
sole discretion of Ixion, and that any form of recognition shall be decided on
a 
<PAGE>   3

                                       2


case by case basis at the sole discretion of Ixion. I further concur that no
term of employment shall be based on the value of any Invention of mine or as
the result of my participation in Ixion inventions.


                            ASSIGNMENT OF INVENTIONS


I hereby assign to Ixion all my right, title, and interest in and to any and all
Ixion Inventions full title to which may be required to be valid for any purpose
worldwide. I also agree here to use my best efforts to assist Ixion in the
application and prosecution of such inventions while employed and beyond the
term of my employment. My obligation to assign shall not apply to any Invention
about which I can prove by clear, cogent, and convincing evidence that:

        a)  it was developed entirely on my own time; and

        b)  no trade secret information of Ixion was used in its development;
            and 

        c)  it does not relate directly to the business purposes and interests
            of Ixion as set forth in the Ixion Mission Statement, and

        d)  it does not directly or substantially result from any work
            performed by me for Ixion.

I have attached hereto a list describing all patented, copyrighted, or
otherwise documented Inventions which are my property and which were made prior
to the date of this agreement with Ixion that I wish to exclude from this
Assignment. 

                   NON-COMPETITION AND TERMINATION PROVISIONS

I agree that, for a stated period of time following the termination of my
employment, I will not, beyond passive investment, either directly or
indirectly own, manage, operate, join, control, or participate in the
ownership, management, operation or control of, or become an employee, service
technician, agent, or sales representative of, or consultant or advisor to, any
business, person, customer, or other entity, which engages in any activity
that creates competition with Ixion's Business purposes and interest as set out
in the last Ixion Mission Statement preceding my date of termination. If I as
an employee effect the termination, that period will be two (2) years. If Ixion
effects the termination with just cause, that period will be (2) years, and if
Ixion effects the termination for any cause, that period will be (9) months.
This will apply work with companies worldwide, including specifically the
United States, Western Europe, Japan, Canada, Mexico, Both Chinas, Korea and
Australia. 

I understand that my employment relationship is "at will" and that notice of
termination with or without cause by either an employee or by Ixion will be
considered immediate unless a transitional term is mutually agreed upon by both
parties. I will leave in good order all materials that I have developed with
Ixion and all materials that are the property of Ixion.

                               PERSONAL PROPERTY

I understand that I may voluntarily use my own personal tangible or intangible
property to facilitate my work at Ixion when appropriate, but that Ixion will
not be responsible for its maintenance, rent or other payments, storage,
replacement, damage, or theft or assume any other liability for that property.
If the personal property is used in conjunction with Ixion confidential
material -- such as computer software -- then that material will remain as 
<PAGE>   4

                                       3

confidential as if it were within the physical confines of Ixion. I understand
that Ixion will provide fire and theft insurance for my possessions while they
are on Ixion's premises to the extent such possessions are covered by Ixion
insurance and as long as Ixion property is fully compensated first.

                                ENTIRE AGREEMENT

I understand that this Agreement shall be governed for all purposes by laws of
the state of Washington as such laws apply to contracts to be performed within
Washington by residents of Washington and that venue for any action arising out
of this Agreement shall be properly laid in King County, Washington or in the
Federal District Court for the Western District of Washington or at the
employee's then-current residence, at Ixion's option. If any provision of this
Agreement shall be declared excessively broad, it shall be construed so as to
afford Ixion the maximum protection permissible by law. If any provision of
this agreement is void or is so declared, such provisions shall be severed from
this Agreement, which shall otherwise remain in full force and effect. I agree
that in case of such a breach irreparable harm may be suffered by Ixion for
which remedies at law may not adequately compensate and therefore Ixion shall be
entitled to obtain injunctive or other equitable relief against Employee in any
court in addition to any damages which might be proved. Should it be necessary
for either party to enforce this agreement, the court shall award the
prevailing party attorney's fees, costs, expenses, legal assistant and expert
fees reasonably incurred to enforce or defend parties' rights under this
agreement. 

This agreement sets forth the entire Agreement of the parties as to my duties
to Ixion regarding rights, non-disclosure and non-competition, and supercedes
any prior non-disclosure or non-compete agreements. Any representations,
promises, or conditions in connection therewith will not apply except for
pre-existing products or conditions of which I have notified Ixion in writing
and which Ixion has subsequently acknowledged and agreed. Any waiver of any
breach of this Agreement or failure to enforce its provisions shall not
operate, or be construed as, a waiver of any subsequent or prior breach by any
party. The terms and conditions of this Agreement shall survive my employment
termination. This agreement may be modified, amended, or superceded only by a
separate written instrument executed by both IXION and Employee.

I HAVE READ AND FULLY UNDERSTAND THIS AGREEMENT WITH IXION

                           INDEMNIFICATION AGREEMENT

                THIS AGREEMENT is made and entered into this _____ day of
_________________________,1996 between Interact Medical Technologies
Corporation, a Delaware corporation ("Corporation"), and ______________________
("Director").

                                   RECITALS:

                A. Director, a member of the Board of Directors of Corporation,
performs a valuable service in such capacity for Corporation; and

                B. The stockholders of Corporation have adopted Bylaws (the
"Bylaws") providing for the indemnification of its Directors and executive
officers to the fullest extent not prohibited by the Delaware General
Corporation Law, as amended (the "Code"); and

                C. The Bylaws and the Code, by their non-exclusive nature,
permit contracts between Corporation and the members of its Board of Directors
with respect to indemnification of such directors; and

                D. In accordance with the authorization as provided by the Code,
Corporation may purchase and maintain a policy or policies of Directors and
Officers Liability Insurance ("D & 0 Insurance"), covering certain liabilities
which may be incurred by its directors and officers in the performance as
directors and officers of Corporation; and

                E. As a result of developments affecting the terms, scope and
availability of D & O Insurance, there exists general uncertainty as to the
extent of protection afforded members of the Board of Directors by such D & O
Insurance, if any, and by statutory and by-law indemnification provisions; and

                F. In order to induce Director to continue to serve as a member
of the Board of Directors of Corporation, Corporation has determined and agreed
to enter into this contract with Director.

                NOW, THEREFORE, in consideration of Director's continued service
as a director after the date hereof, the parties hereto agree as follows:

                1. Indemnity of Director. Corporation hereby agrees to hold
harmless and indemnify Director to the fullest extent authorized or permitted by
the provisions of the Code, as may be amended from time to time.

                2. Additional Indemnity. Subject only to the exclusions set
forth in Section 3 hereof, Corporation hereby further agrees to hold harmless
and indemnify Director:


<PAGE>   3


                (a) against any and all expenses (including attorneys' fees),
witness fees, judgments, fines and amounts paid in settlement actually and
reasonably incurred by Director in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (including an action by or in the right of Corporation) to which
Director is, was or at any time becomes a party, or is threatened to be made a
party, by reason of the fact that Director is, was or at any time becomes a
director, officer, employee or agent of Corporation, or is or was serving or at
any time serves at the request of Corporation as a director, officer, employee
or agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise; and

                (b) otherwise to the fullest extent as may be provided to
Director by Corporation under the non-exclusivity provisions of the Bylaws of
Corporation and the Code.

        3. Limitations on Additional Indemnity. No indemnity pursuant to Section
2 hereof shall be paid by Corporation:

                (a) except to the extent the aggregate of losses to be
indemnified thereunder exceeds the sum of such losses for which the Director is
indemnified pursuant to Section 1 hereof or pursuant to any D & 0 Insurance
purchased and maintained by Corporation;

                (b) in respect to remuneration paid to Director if it shall be
determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

                (c) on account of any suit in which judgment is rendered against
Director for an accounting of profits made from the purchase or sale by Director
of securities of Corporation pursuant to the provisions of Section 16(b) of the
Securities Exchange Act of 1934 and amendments thereto or similar provisions of
any federal, state or local statutory law;

                (d) on account of Director's conduct which is finally adjudged
to have been knowingly fraudulent or deliberately dishonest, or to constitute
willful misconduct;

                (e) on account of Director's conduct which is the subject of an
action, suit or proceeding described in Section 7(c)(ii) hereof;

                (f) on account of any action, claim or proceeding (other than a
proceeding referred to in Section 8(b) hereof) initiated by the Director unless
such action, claim or proceeding was authorized in the specific case by action
of the Board of Directors;

                (g) if a final decision by a Court having jurisdiction in the
matter shall determine that such indemnification is not lawful (and, in this
respect, both Corporation

                                      -2-
<PAGE>   4


and Director have been advised that the Securities and Exchange Commission
believes that indemnification for liabilities arising under the federal
securities laws is against public policy and is, therefore, unenforceable and
that claims for indemnification should be submitted to appropriate courts for
adjudication).

        4. Contribution. If the indemnification provided in Sections 1 and 2
hereof is unavailable by reason of a Court decision described in Section 3(g)
hereof based on grounds other than any of those set forth in paragraphs (b)
through (f) of Section 3 hereof, then in respect of any threatened, pending or
completed action, suit or proceeding in which Corporation is jointly liable with
Director (or would be if joined in such action, suit or proceeding), Corporation
shall contribute to the amount of expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
and paid or payable by Director in such proportion as is appropriate to reflect
(i) the relative benefits received by Corporation on the one hand and Director
on the other hand from the transaction from which such action, suit or
proceeding arose, and (ii) the relative fault of Corporation on the one hand and
of Director on the other in connection with the events which resulted in such
expenses, judgments, fines or settlement amounts, as well as any other relevant
equitable considerations. The relative fault of Corporation on the one hand and
of Director on the other shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such expenses,
judgments, fines or settlement amounts. Corporation agrees that it would not be
just and equitable if contribution pursuant to this Section 4 were determined by
pro rata allocation or any other method of allocation which does not take
account of the foregoing equitable considerations.

        5. Continuation of Obligations. All agreements and obligations of
Corporation contained herein shall continue during the period Director is a
director, officer, employee or agent of Corporation (or is or was serving at the
request of Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise) and shall continue thereafter so long as Director shall be subject
to any possible claim or threatened, pending or completed action, suit or
proceeding, whether civil, criminal or investigative, by reason of the fact that
Director was a director of Corporation or serving in any other capacity referred
to herein.

        6. Notification and Defense of Claim. Not later than thirty (30) days
after receipt by Director of notice of the commencement of any action, suit or
proceeding, Director will, if a claim in respect thereof is to be made against
Corporation under this Agreement, notify Corporation of the commencement
thereof; but the omission so to notify Corporation will not relieve it from any
liability which it may have to Director otherwise than under this Agreement.
With respect to any such action, suit or proceeding as to which Director
notifies Corporation of the commencement thereof:

                (a) Corporation will be entitled to participate therein at its
own expense;

                                      -3-


<PAGE>   5
                (b) except as otherwise provided below, to the extent that it
may wish, Corporation jointly with any other indemnifying party similarly
notified will be entitled to assume the defense thereof, with counsel reasonably
satisfactory to Director. After notice from Corporation to Director of its
election so as to assume the defense thereof, Corporation will not be liable to
Director under this Agreement for any legal or other expenses subsequently
incurred by Director in connection with the defense thereof other than
reasonable costs of investigation or as otherwise provided below. Director shall
have the right to employ its counsel in such action, suit or proceeding but the
fees and expenses of such counsel incurred after notice from Corporation of its
assumption of the defense thereof shall be at the expense of Director unless (i)
the employment of counsel by Director has been authorized by Corporation, (ii)
Director shall have reasonably concluded that there may be a conflict of
interest between Corporation and Director in the conduct of the defense of such
action or (iii) Corporation shall not in fact have employed counsel to assume
the defense of such action, in each of which cases the fees and expenses of
Director's separate counsel shall be at the expense of Corporation. Corporation
shall not be entitled to assume the defense of any action, suit or proceeding
brought by or on behalf of Corporation or as to which Director shall have made
the conclusion provided for in (ii) above; and

                (c) Corporation shall not be liable to indemnify Director under
this Agreement for any amounts paid in settlement of any action or claim
effected without its written consent. Corporation shall be permitted to settle
any action except that it shall not settle any action or claim in any manner
which would impose any penalty or limitation on Director without Director's
written consent. Neither Corporation nor Director will unreasonably withhold its
consent to any proposed settlement.

        7. Advancement and Repayment of Expenses.

                (a) In the event that Director employs his own counsel pursuant
to Section 6(b)(i) through (iii) above, Corporation shall advance to Director,
prior to any final disposition of any threatened or pending action, suit or
proceeding, whether civil, criminal, administrative or investigative, any and
all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding within ten (10)
days after receiving copies of invoices presented to Director for such expenses.

                (b) Director agrees that Director will reimburse Corporation for
all reasonable expenses paid by Corporation in defending any civil or criminal
action, suit or proceeding against Director in the event and only to the extent
it shall be ultimately determined by a final judicial decision (from which there
is no right of appeal) that Director is not entitled, under the provisions of
the Code, the Bylaws, this Agreement or otherwise, to be indemnified by
Corporation for such expenses.

                (c) Notwithstanding the foregoing, Corporation shall not be
required to advance such expenses to Director if Director (i) commences any
action, suit or proceeding as a plaintiff unless such advance is specifically
approved by a majority of the

                                      -4-
<PAGE>   6


Board of Directors or (ii) is a party to an action, suit or proceeding brought
by Corporation and approved by a majority of the Board which alleges willful
misappropriation of corporate assets by Director, disclosure of confidential
information in violation of Director's fiduciary or contractual obligations to
Corporation, or any other willful and deliberate breach in bad faith of
Director's duty to Corporation or its stockholders.

                8. Enforcement.

                (a) Corporation expressly confirms and agrees that it has
entered into this Agreement and assumed the obligations imposed on Corporation
hereby in order to induce Director to continue as a director of Corporation, and
acknowledges that Director is relying upon this Agreement in continuing in such
capacity.

                (b) In the event Director is required to bring any action to
enforce rights or to collect moneys due under this Agreement and is successful
in such action, the Corporation shall reimburse Director for all Director's
reasonable fees and expenses in bringing and pursuing such action.

                9. Subrogation. In the event of payment under this agreement,
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Director, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable
Corporation effectively to bring suit to enforce such rights.

                10. Non-Exclusivity of Rights. The rights conferred on Director
by this Agreement shall not be exclusive of any other right which Director may
have or hereafter acquire under any statute, provision of Corporation's
Certificate of Incorporation or Bylaws, agreement, vote of stockholders or
directors, or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office.

                11. Survival of Rights. The rights conferred on Director by this
Agreement shall continue after Director has ceased to be a director, officer,
employee or other agent of Corporation and shall inure to the benefit of
Director's heirs, executors and administrators.

                12. Separability. Each of the provisions of this Agreement is a
separate and distinct agreement and independent of the others, so that if any or
all of the provisions hereof shall be held to be invalid or unenforceable for
any reason, such invalidity or unenforceability shall not affect the validity or
enforceability of the other provisions hereof or the obligation of the
Corporation to indemnify the Director to the full extent provided by the Bylaws
or the Code.

                13. Governing Law. This Agreement shall be interpreted and
enforced in accordance with the laws of the State of Delaware.

                                      -5-
<PAGE>   7
                14. Binding Effect. This Agreement shall be binding upon
Director and upon Corporation, its successors and assigns, and shall inure to
the benefit of Director, his heirs, personal representatives and assigns and to
the benefit of Corporation, its successors and assigns.

                15. Amendment and Termination. No amendment, modification,
termination or cancellation of this Agreement shall be effective unless in
writing signed by both parties hereto.

                16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

proceeding referred to in Section 8(b) hereof) initiated by Officer unless such
action, claim or proceeding was authorized in the specific case by action of the
Board of Directors; or

         (g) if a final decision by a Court having jurisdiction in the matter
shall determine that such indemnification is not lawful (and, in this respect,
both Corporation

                                      -2-
<PAGE>   4
and Officer have been advised that the Securities and Exchange Commission
believes that indemnification for liabilities arising under the federal
securities laws is against public policy and is, therefore, unenforceable and
that claims for indemnification should be submitted to appropriate courts for
adjudication).

    4. Contribution. If the indemnification provided in Sections 1 and 2 hereof
is unavailable by reason of a Court decision described in Section 3(g) hereof
based on grounds other than any of those set forth in paragraphs (b) through (f)
of Section 3 hereof, then in respect of any threatened, pending or completed
action, suit or proceeding in which Corporation is jointly liable with Officer
(or would be if joined in such action, suit or proceeding), Corporation shall
contribute to the amount of expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred and paid
or payable by Officer in such proportion as is appropriate to reflect (i) the
relative benefits received by Corporation on the one hand and Officer on the
other from the transaction from which such action, suit or proceeding arose, and
(ii) the relative fault of Corporation on the one hand and of Officer on the
other in connection with the events which resulted in such expenses, judgments,
fines or settlement amounts, as well as any other relevant equitable
considerations. The relative fault of Corporation on the one hand and of Officer
on the other shall be determined by reference to, among other things, the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent the circumstances resulting in such expenses, judgments,
fines or settlement amounts. Corporation agrees that it would not be just and
equitable if contribution pursuant to this Section 4 were determined by pro rata
allocation or any other method of allocation which does not take account of the
foregoing equitable considerations.

    5. Continuation of Obligations. All agreements and obligations of
Corporation contained herein shall continue during the period Officer is a
director, officer, employee or agent of Corporation (or is or was serving at the
request of Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise) and shall continue thereafter so long as Officer shall be subject to
any possible claim or threatened, pending or completed action, suit or
proceeding, whether civil, criminal or investigative, by reason of the fact that
Officer was an officer of Corporation or serving in any other capacity referred
to herein.

    6. Notification and Defense of Claim. Not later than thirty (30) days after
receipt by Officer of notice of the commencement of any action, suit or
proceeding, Officer will, if a claim in respect thereof is to be made against
Corporation under this Agreement, notify Corporation of the commencement
thereof; but the omission so to notify Corporation will not relieve it from any
liability which it may have to Officer otherwise than under this Agreement. With
respect to any such action, suit or proceeding as to which Officer notifies
Corporation of the commencement thereof:

         (a) Corporation will be entitled to participate therein at its own
expense;

                                      -3-
<PAGE>   5
         (b) except as otherwise provided below, to the extent that it may wish,
Corporation jointly with any other indemnifying party similarly notified will be
entitled to assume the defense thereof, with counsel reasonably satisfactory to
Officer. After notice from Corporation to Officer of its election so as to
assume the defense thereof, Corporation will not be liable to Officer under this
Agreement for any legal or other expenses subsequently incurred by Officer in
connection with the defense thereof other than reasonable costs of investigation
or as otherwise provided below. Officer shall have the right to employ his or
her own counsel in such action, suit or proceeding but the fees and expenses of
such counsel incurred after notice from Corporation of its assumption of the
defense thereof shall be at the expense of Officer unless (i) the employment of
counsel by Officer has been authorized by Corporation, (ii) Officer shall have
reasonably concluded that there may be a conflict of interest between
Corporation and Officer in the conduct of the defense of such action or (iii)
Corporation shall not in fact have employed counsel to assume the defense of
such action, in each of which cases the fees and expenses of Officer's separate
counsel shall be at the expense of Corporation. Corporation shall not be
entitled to assume the defense of any action, suit or proceeding brought by or
on behalf of Corporation or as to which Officer shall have made the conclusion
provided for in (ii) above; and

         (c) Corporation shall not be liable to indemnify Officer under this
Agreement for any amounts paid in settlement of any action or claim effected
without its written consent. Corporation shall be permitted to settle any action
except that it shall not settle any action or claim in any manner which would
impose any penalty or limitation on Officer without Officer's written consent.
Neither Corporation nor Officer will unreasonably withhold its or his or her
consent to any proposed settlement.

    7. Advancement and Repayment of Expenses.

         (a) In the event that Officer employs his or her own counsel pursuant
to Section 6(b)(i) through (iii) above, Corporation shall advance to Officer,
prior to any final disposition of any threatened or pending action, suit or
proceeding, whether civil , criminal, administrative or investigative, any and
all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding within ten (10)
days after receiving copies of invoices presented to Officer for such expenses.

         (b) Officer agrees that Officer will reimburse Corporation for all
reasonable expenses paid by Corporation in defending any civil or criminal
action, suit or proceeding against Officer in the event and only to the extent
it shall be ultimately determined by a final judicial decision (from which there
is no right of appeal) that Officer is not entitled, under the provisions of the
Code, the Bylaws, this Agreement or otherwise, to be indemnified by Corporation
for such expenses.

         (c) Notwithstanding the foregoing, Corporation shall not be required to
advance such expenses to Officer if Officer (i) commences any action, suit or
proceeding as a plaintiff unless such advance is specifically approved by a
majority of the Board of

                                       -4-
<PAGE>   6
Directors or (ii) is a party to an action, suit or proceeding brought by
Corporation and approved by a majority of the Board which alleges willful
misappropriation of corporate assets by Officer, disclosure of confidential
information in violation of Officer's fiduciary or contractual obligations to
Corporation, or any other willful and deliberate breach in bad faith of
Officer's duty to Corporation or its stockholders.

    8. Enforcement.

         (a) Corporation expressly confirms and agrees that it has entered into
this Agreement and assumed the obligations imposed on Corporation hereby in
order to induce Officer to continue as an officer of Corporation, and
acknowledges that Officer is relying upon this Agreement in continuing in such
capacity.

         (b) In the event Officer is required to bring any action to enforce
rights or to collect moneys due under this Agreement and is successful in such
action , Corporation shall reimburse Officer for all of Officer's reasonable
fees and expenses in bringing and pursuing such action.

    9. Subrogation. In the event of payment under this agreement, Corporation
shall be subrogated to the extent of such payment to all of the rights of
recovery of Officer, who shall execute all documents required and shall do all
acts that may be necessary to secure such rights and to enable Corporation
effectively to bring suit to enforce such rights.

    10. Non-Exclusivity of Rights. The rights conferred on Officer by this
Agreement shall not be exclusive of any other right which Officer may have or
hereafter acquire under any statute, provision of Corporation's Certificate of
Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.

    11. Survival of Rights. The rights conferred on Officer by this Agreement
shall continue after Officer has ceased to be a director, officer, employee or
other agent of Corporation and shall inure to the benefit of Officer's heirs,
executors and administrators.

    12. Separability. Each of the provisions of this Agreement is a separate and
distinct agreement and independent of the others, so that if any or all of the
provisions hereof shall be held to be invalid or unenforceable for any reason,
such invalidity or unenforceability shall not affect the validity or
enforceability of the other provisions hereof or the obligation of Corporation
to indemnify Officer to the full extent provided by the Bylaws or the Code.

    13. Governing Law. This Agreement shall be interpreted and enforced in
accordance with the laws of the State of Delaware.

                                       -5-
<PAGE>   7
    14. Binding Effect. This Agreement shall be binding upon Officer and upon
Corporation, its successors and assigns, and shall inure to the benefit of
Officer, his or her heirs, personal representatives and assigns and to the
benefit of Corporation, its successors and assigns.

    15. Amendment and Termination. No amendment, modification, termination or
cancellation of this Agreement shall be effective unless in writing signed by
both parties hereto.

    16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

David Dlesk
Chief Executive Officer
Medical Media Systems
79 E. Wilder Road

West Lebanon, NH 03784-3106

Dear David:

Thank you for forwarding your comments regarding our contractual agreement.
This letter summarizes the key elements of the working relationship between
Baxter and Medical Media Systems (MMS). All of your comments have been
included.

MMS products are intended to facilitate visualization and decision making
during delicate surgical procedures such as ACL reconstruction or resection of
liver metastases.

Initially, MMS intends to offer a "Preview" product, a software platform that
allows the reconstruction of a set of 2-D images (e.g. NMR, CT, ultrasound
images) into a 3-D model, which can then be viewed on a computer screen in
different dimensions and at various angles. The "Preview" product will be
offered only for resection of liver metastases procedures.

At a later time, MMS will introduce a more advanced product, the "CompuScope"
device, which, in addition to the above, allows for superposition of the
computer 3-D image to a real-time video image. The "CompuScope" device is
valuable for both ACL reconstruction and resection of liver metastases
procedures. 

Preliminary timelines discussed in the meeting are as follows:

- - -  A regulatory strategy for the "Preview" product is needed by November 94.

- - -  Regulatory support is needed in preparation for the American College of
   Surgeons Meeting in Chicago (October 13-15, 1994)

- - -  Clinical/Marketing trials are planned for Q3, 1995 to evaluate the
   "CompuScope" product. "Preview" trials are planned for Q1, 1995.

                                                        October 17, 1994
                                                                  Page 2


It is estimated that a regulatory professional will be needed by MMS at a half
time capacity for the coming year. As projects and submissions develop, more
time commitment may be required. I.V. Systems Regulatory Affairs is willing to
commit the equivalent of a professional's half time for the next two years, in
form of professional, managerial and support time. We understand some travel is
involved. We discussed $60,000/year and funding for travel or other
miscellaneous expenses to be provided by MMS. We would like to keep any
administrative mechanics of this project as straight forward as possible. We
propose a fee of $15,000 due at the beginning of every quarter and that
additional bills for travel or other miscellaneous expenses be sent directly to
you.

If you concur with this arrangement, please sign and return a copy of this
letter. Dated signatures concurring with this letter could be used as the
agreement between us. I have also attached a standard confidentiality agreement
letter for your signature. Such letter is needed if we are to provide you with
examples of previous submissions or other Baxter confidential documents.

I look forward to the opportunity of working with you and your team.

Sincerely,

/s/ Tamima Itani

<PAGE>   2
                                CREDIT AGREEMENT

        This Credit Agreement (this "Agreement"), dated as of April 10, 1996,
is by and between Baxter Healthcare Corporation, a Delaware corporation
("Baxter"), having an office at 17221 Redhill Avenue, Irvine, California 92714,
and Medical Media Systems, a New Hampshire general partnership ("MMS"), having
an office at 79 East Wilder Road, West Lebanon, New Hampshire 03784.

                                    RECITALS

        As of December 22, 1995, Baxter had advanced $400,000 to MMS for the
purpose of funding MMS' continuing operations. At MMS' request, Baxter is now
advancing to MMS an additional $150,000 to fund MMS' continuing operations.
Baxter and MMS now desire to consolidate these advances into one $550,000 loan
on the terms and subject to the conditions set forth in this Agreement.

                                   AGREEMENT

        NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree:

        1.      Loans.  Baxter agrees, on the terms and conditions of this
Agreement, to make one or more loans to MMS during the period from the date
hereof through April 30, 1996 in an aggregate principal amount not exceeding
One Hundred Fifty Thousand Dollars ($150,000). In addition, MMS confirms that
it has already borrowed and received the sum of $400,000 from Baxter as a
non-interest bearing, due on demand, loan which, as of the date of this
Agreement, will be governed by the terms and subject to the conditions set
forth in this Agreement. Once any loan has been made by Baxter, MMS shall not
have any right to reborrow any amount repaid to Baxter by MMS.

        2.      Notice of Borrowing.  Whenever MMS desires to borrow funds
under this Agreement, it shall deliver to Baxter written notice specifying the
amount to be borrowed and the date on which such borrowing is requested to be
made. Subject to the terms and conditions of this Agreement, Baxter shall make
such funds available to MMS to an account designated by MMS not later than ten
(10) business days after receipt of the request for borrowing.

        3.      Promissory Note.  Loans and advances made under this Agreement
shall be consolidated into a single promissory note for $550,000 (the "Note")
of MMS, payable upon demand. The date and amount of each loan made under this
Agreement and each payment made on account of principal and/or interest
outstanding shall be recorded by Baxter on its books, as appropriate. All such
recordations shall be conclusive absent manifest error.

<PAGE>   3
        4.      Prepayments.  MMS shall have the right to prepay, in whole or
in part, the principal balance then outstanding under the Note plus accrued
interest at any time and without any premium or penalty. Such prepayment shall
be first applied to accrued interest and other sums then due under the Note
with the balance then being applied against the outstanding principal balance
of the Note.

        5.      Due Date.  The Note shall be due upon demand by Baxter.

        6.      Interest.  Interest on loans and advances evidenced by the Note
shall accrue at the rate of six percent (6%) per annum or such lesser rate as
shall be the maximum rate applicable on legal contracts. Interest shall be paid
annually on December 31.

        7.      Payments.  All payments of principal, interest and other
amounts to be made by MMS under this Agreement or the Note shall be made in
U.S. dollars, in immediately available funds, without deductions, offsets or
counterclaim. 

        8.      Miscellaneous.

                (a)     Notices.  Any notice or any communication required or
permitted to be given shall be in writing, and may be personally served,
telecopied, telexed or sent by United States mail, and shall be deemed to have
been given and delivered in person, upon receipt of telecopy or telex or four
(4) business days after deposit in the United States mail, registered or
certified with postage prepaid and addressed as indicated in the introductory
paragraph of this Agreement.

                (b)     Amendments.  Except as otherwise expressly provided in
this Agreement, any provision of this Agreement may be amended and modified
only by an instrument in writing signed by Baxter and MMS.

                (c)     Entire Agreement.  This Agreement (including the Note)
constitutes the entire contract between the parties relative to the subject
matter hereof. Any previous agreement among the parties with respect to the
subject matter hereof is superseded by this Agreement and the Note.

                (d)     Successors and Assigns.  This Agreement shall be
binding and inure to the benefit of the parties hereto and their respective
successors or permitted assigns.

                (e)     Counterparts.  This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and
the same instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart.

                (f)     Governing Law.  This Agreement and Note shall be
governed by, and construed in accordance with, the laws of the State of
California.
