                               LUMISYS INCORPORATED

                                   THE COMPANY

The Company designs, manufactures and markets a family of precision digitizers 
that convert medical images on film or video into digital format.  Once in 
digital form, the medical images can be stored, transmitted, viewed, enhanced, 
manipulated and printed at any PC or workstation within a medical network.  The 
Company currently offers a comprehensive family of products for digitizing 
medical film images under the Lumiscan label and video images under the 
Imagraph name.  These digitizers process images from all commercially available 
medical imaging modalities, including x-ray, computed tomography ("CT"), 
magnetic resonance imaging ("MRI"), ultrasound and nuclear medicine.  The 
Company is the leading supplier of laser-based film digitizers, with sales of 
over 3,000 Lumiscan units since its first product was introduced in 1990.  In 
early 1996, the Company introduced its charge-coupled device ("CCD") based 
digitizer.  The Company also offers under the Imagraph label high quality 
board-level digitization and compression products for the capture of video 
images, which have applications in medical imaging as well as in scientific and 
industrial inspection and multimedia imaging.

In 1996, the Company introduced a computed radiography ("CR") system for use in 
the industrial inspection market.  The CR system reads images from reusable 
phosphor plates of pipes, valves, aircraft parts and other structural objects.

The Company intends to maintain and enhance its market leadership by leveraging 
its reputation for high quality, reliable and cost-effective products, 
broadening its product lines through internal products development, acquiring 
complementary businesses or technologies and penetrating new geographic 
markets.  The Company sells its products primarily to OEMs and VARs, who then 
integrate the Company's products into teleradiology and Picture Archiving and 
Communication Systems ("PACS") networks.  The Company has established close 
working relationships with the leading suppliers of these systems including 
Agfa Gavaert N.V. ("Agfa"), CEMAX-ICON Imation ("CEMAX"), a subsidiary of 
Imation Corporation, E-Med Systems ("E-Med") and E-System Medical Electronics 
Inc. company, which is a subsidiary of Raytheon Corp., Eastman Kodak Company 
("Kodak"), Olicon Corporation ("Olicon") and Sterling Diagnostics ("Sterling," 
formerly the medical group of E.I. DuPont de Nemours and Company).

Through the acquisition of CompuRAD, Inc. in late 1997, the Company also became 
a leading provider of software that enables healthcare clinicians to access 
medical images and clinical information at any point of care.  The Company 
pioneered the use of personal computer software in the point to point, on call 
teleradiology market, with the introduction of its PC Teleradiology product.  
In response to the increasing acceptance of teleradiology and increasing demand 
for multi-user and multi-access off-site teleradiology systems, the Company 
introduced its iNET product line in late 1994.  In 1997, the Company introduced 
ClinicalWare, an Internet/Intranet software solution which provides secure 
electronic access through a Web browser to clinical information systems at any 
point of care.

The Company sells its software products both through a direct sales force and 
indirectly through a network of VARs and large medical image equiment vendors. 
 The Company's resellers include Konica Medical Corporation ("Konica Medical") 
and National Imaging Resources, a nationwide consortium of X-ray dealers.  The 
Company presently has licensed its products to hopitals, clinics and other 
healthcare facilities and physician groups.  The Company's customers include 
New York University Medical Center, Alliant Heath Systems, Symphony Mobilex, a 
subsidiary of Health Services, Inc. ("Symphony Mobilex") and The Nursing Home 
Group plus many other leading healthcare facilities and organizations.

The principal executive offices of the Company are located at 225 Humboldt 
Court, Sunnyvale, California 94089, and its telephone number is (408) 733-6565. 
 The Company was incorporated in California in 1987 and was reincorporated in 
Delaware in 1995 prior to the completion of its initial public offering.

                                  RISK FACTORS

AN INVESTMENT IN THE SECURITIES OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK. 
 IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK 
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE 
SECURITIES OFFERED HEREBY.

SIGNIFICANT FLUCTUATIONS IN OPERATING RESULTS.  There can be no assurance that 
the Company will be profitable on a quarterly or annual basis in the future.  
The Company has experienced quarterly fluctuations in operating results caused 
by various factors, including the timing of orders by major customers, customer 
inventory levels, shifts in product mix, the incurrence of acquisition-related 
costs and general conditions in the healthcare industry which have reduced 
capital equipment budgets and delayed or reduced the adoption of teleradiology, 
and expects that these fluctuations will continue.

The Company typically does not obtain long-term volume purchase contracts from 
its customers, and a substantial portion of the Company's backlog is scheduled 
for delivery within 90 days or less.  Customers may cancel orders and change 
volume levels or delivery times without penalty.  Quarterly sales and operating 
results therefore depend on the volume and timing of the backlog as well as 
bookings received during the quarter.  A significant portion of the Company's 
operating expenses are fixed, and planned expenditures are based primarily on 
sales forecasts and product development programs.  If sales do not meet the 
Company's expectations in any given period, the material adverse impact on 
operating results may be magnified by the Company's inability to adjust 
operating expenses sufficiently or quickly enough to compensate for such a 
shortfall.  Furthermore, the Company gross margins may decrease in the future 
due to increasing sales of lower margin products and volume discounts.  Results 
of operations in any period should not be considered indicative of the results 
to be expected for any future period.  Fluctuations in operating results may 
also result in fluctuations in the price of the Company's Common Stock.

DEPENDENCE ON TELERADIOLOGY MARKET; UNCERTAINTY OF MARKET ACCEPTANCE.  The 
Company's success is dependent on market acceptance of its new and existing 
products.  The Company's revenues are derived from the sales of medical image 
digitizers for the teleradiology and other medical markets.  There can be no 
assurance that sales of new products will achieve significant market acceptance 
in the future.  In addition, third party payers, such as governmental programs 
and private insurance plans, can indirectly affect the pricing or the relative 
attractiveness of the Company's' products by regulating the maximum amount of 
reimbursement that they will provide for the taking, storing and interpretation 
of medical images.  A decrease in the reimbursement amounts for radiological 
procedures may decrease the amount which physicians, clinics and hospitals are 
able to charge patients for such services.  As a result, adoption of 
teleradiology may slow as capital investment budgets are reduced, thereby 
significantly reducing the demand for the Company's products.

NEW PRODUCT DEVELOPMENT IN SOFTWARE PRODUCTS.  The market for 
Internet/Intranet-related software designed for use in healthcare environments 
is in the early stages of development. Since this market is new, and because 
current and future competitors are likely to introduce competing 
Internet/Intranet software, it is difficult to predict the rate at which the 
market will grow, if at all, or the rate at which new or increased competition 
will result in market saturation.  The Company's ClinicalWare product was only 
recently introduced in 1997 and is highly dependent upon the market acceptance 
of the Internet/Intranet technologies for healthcare environments. If the 
market for such Internet/ Intranet software fails to grow or grows more slowly 
than anticipated, the Company's business, financial condition and results of 
operations would be materially adversely effected.  The Company has had only 
limited shipments of ClinicalWare and expects that the sales cycle for 
ClinicalWare will be longer than that for its other existing products and that 
the price for ClinicalWare will be higher than that for the Company's other 
current products. Accordingly, the Company's quarterly revenues and operating 
results may be subject to greater fluctuation as the Company begins to market 
and sell ClinicalWare. Additionally, the Company faces greater challenges in 
installing and supporting ClinicalWare because of the complexity of 
Internet/Intranet related software and systems.  The Company has limited 
experience in marketing, installing and supporting Internet/Intranet clinical 
information systems, and there can be no assurance that the Company can obtain 
the necessary resources to market, install and support ClinicalWare in an 
efficient, cost-effective and competitive manner. The failure of ClinicalWare 
to achieve market acceptance for any reason could have a materially adverse 
effect on the Company's business, financial condition and results of 
operations.

SIGNIFICANT RISKS ASSOCIATED WITH FUTURE ACQUISITIONS.  The Company expects to 
pursue acquisitions of complementary technologies, product lines or businesses 
in the future.  The integration of any future acquisitions will require special 
attention from management, which may temporarily distract its attention from 
the day-to-day business of the Company.  Any future acquisitions will also 
require integration of the companies' product offerings and coordination of 
research and development and sales and marketing activities.  Furthermore, as a 
result of acquisitions, the Company may enter markets in which it has little or 
no direct prior experience.  There can also be no assurance that the Company 
will be able to retain key technical personnel of an acquired company or 
recruit new management personnel for the acquired businesses, or that the 
Company will, or may in the future, realize any benefits as a result of such 
acquisitions.  Future acquisitions by the Company may result in potentially 
dilutive issuances of equity securities, the incurrence of debt, one-time 
acquisition charges and amortization expenses related to goodwill and 
intangible assets, each of which could be significant and could materially 
adversely affect the Company's financial condition and results of operations.  
In addition, the Company believes that it may be required to expand and enhance 
its financial and management controls, reporting systems and procedures as it 
integrates potential future acquisitions.  There can be no assurance that the 
Company will be able to do so effectively, and failure to do so when necessary 
would have a material adverse effect upon the Company's business and results of 
operations.

NEW PRODUCT DEVELOPMENT IN IMAGE DIGITIZERS; RAPID TECHNOLOGICAL CHANGE.  The 
market for the Company's products is characterized by rapid technological 
advances, changes in customer requirements and frequent new product 
introductions and enhancements.  The Company's future success will depend upon 
its ability to enhance its current products, to develop and introduce new 
products that keep pace with technological developments and to respond to 
evolving customer requirements.  Any failure by the Company to anticipate or 
respond adequately to technological developments by its competitors or to 
changes in customer requirements, or any significant delays in product 
development or introduction, could result in a loss of competitiveness or 
revenues.  In the past, the Company has occasionally experienced delays in the 
development and introduction of new products and product enhancements, and 
there can be no assurance that the Company will not experience such delays in 
the future.  In addition, new product introductions or enhancements by the 
Company's competitors or the use of other technologies that do not depend on 
film digitization could cause a decline in sales or loss of market acceptance 
of the Company's products.  In particular, computed radiography ("CR") systems 
are currently available and have been sold for medical applications for over 
ten years with limited acceptance.  In addition, several companies have 
announced developments leveraging the technology used in flat panel displays, 
digital radiography ("DR"), to produce high-resolution, two dimensional image 
sensor arrays that make it possible for x-ray images to be captured digitally 
without film or chemical processing. While this emerging technology is 
extensive, there can be no assurance that future advances in this technology or 
other technologies will not produce systems better positioned for the 
marketplace that will therefore reduce the digitizer market to the then 
installed base of imaging systems. There can be no assurance that the Company 
will be successful in developing and marketing new products or product 
enhancements on a timely or cost-effective basis, and such failure could have a 
material adverse effect on the Company's business and results of operations.

RISKS ASSOCIATED WITH SOFTWARE PRODUCTS.  Software and systems as complex as 
those offered by the Company frequently contain undetected errors or failures 
when first introduced or when new versions are released.  The Company has in 
the past discovered bugs and system errors in certain of its software 
enhancements, both before and after initial shipment.  There can be no 
assurance that, despite testing by the Company, errors will not occur in the 
Company's products resulting in loss of, or delay in, market acceptance.  Any 
such loss or delay could have a material adverse effect on the Company's 
business, financial condition and results of operations.  Peripherals and 
hardware from third party manufacturers also may contain defects and 
incompatibilities which could adversely affect market acceptance of the 
Company's software products.

LONG SALES CYCLES.  The sales cycle for medical image management systems is 
lengthy.  The sales cycle of the Company's products is subject to delays 
associated with changes or the anticipation of changes in the regulatory 
environment affecting healthcare enterprises, changes in the customer's 
strategic system initiatives, competing information systems projects within the 
customer organization, consolidation in the healthcare industry in general, the 
highly sophisticated nature of the Company's software and competition in the 
medical image management and healthcare information systems markets in general. 
 The time required from initial contact to purchase order typically ranges from 
one to six months, and the time from purchase order to delivery and recognition 
of revenue typically ranges from one to six months.  During the sales process, 
the Company expends substantial time, effort and funds preparing a contract 
proposal, demonstrating the software and negotiating the purchase order.  For 
these and other reasons, the Company cannot predict when or if the sales 
process with a prospective customer will result in a purchase order.

COMPETITION.  Although to date competition in the United States laser-based 
film digitizer market has not been significant, a new company, Clinical Laser 
Systems ("CLS") entered the market in 1996 with a product similar to the laser-
based film digitizers offered by the Company.  In addition, several Japanese 
competitors, such as Konica Corporation ("Konica"), Nishimoto Sangyo Co., Ltd. 
("Nishimoto Sangyo") and Abe Sekkei Inc. ("Abe Sekkei"), offer competitive 
products on an international basis and may decide in the future to devote 
additional resources to marketing competitive products in the United States.  
The markets for medical film digitizers incorporating charge-coupled devices 
("CCDs") are highly competitive.  The Company faces competition from companies 
such as Vidar Systems Inc., Canon Inc., Vision Ten Inc., Hell Linotype and 
Howtek in the CCD-based film digitizer market.  There can be no assurance that 
the Company's competitors will not develop enhancements to, or future 
generations of, competitive products that will offer superior price or 
performance features that render the Company's products less competitive or 
obsolete.

In addition, large domestic companies, such as Kodak, Imation Corporation 
("Imation"), Sterling and General Electric Co. ("GE"), and European companies, 
such as Siemens, Philips Electrics N.V. ("Philips") and Agfa Gavaert N.V. 
("Agfa"), have the technical and financial ability to design and market 
digitizer products competitive with the Company's products, and some of them 
have in the past produced and marketed such products.  While most of these 
companies currently purchase products from the Company, the Company believes 
that it will be required to continue to improve the price and performance 
characteristics of its products to retain their business especially in view of 
the fact that these customers are not contractually required to purchase their 
digitizers exclusively or at all from the Company.  All of these companies have 
significantly greater financial, marketing and manufacturing resources than the 
Company and would be significant competitors if they decided to enter this 
market.

The markets for medical video image digitizers are also highly competitive.  
Competitors in the video digitizer market are Precision Digital Images Corp., 
Epix, Inc. and Matrox Electronic Systems Ltd.

Competition in the markets for medical image management products and healthcare 
information systems and services is also intense and is expected to increase. 
The Company's competitors include other providers of medical image management 
and healthcare information products. The Company's principal competitors in the 
medical image management industry are E-Med, CEMAX, Applicare Medical Imaging 
B.V. and Access Radiology Corporation. Furthermore, other major healthcare 
information and equipment companies not presently offering competing products 
may enter the Company's markets. In addition, the emerging market for 
Internet/Intranet clinical information systems is expected to be highly 
competitive, and the Company's competitors in this market could include many of 
its competitors in the medical image management systems market as well as other 
providers of healthcare information systems and new entrants into the 
marketplace. Increased competition could result in price reductions, reduced 
gross margins and loss of market share, any of which could materially adversely 
effect the Company's business, financial condition and results of operations. 
In addition, many of the Company's competitors and potential competitors have 
significantly greater financial, technical, product development, marketing and 
other resources and market recognition than the Company in the 
Internet/Intranet clinical information systems area. Many of the Company's 
competitors also currently have, or may develop or acquire, substantial 
installed customer bases in the healthcare industry. As a result of these 
factors, the Company's competitors may be able to respond more quickly to new 
or emerging technologies and changes in customer requirements or to devote 
greater resources to the development, promotion and sale of their products than 
the Company. There can be no assurances that the Company will be able to 
compete successfully against current and future competitors or that competitive 
pressures faced by the Company will not have a materially adverse effect on its 
business, financial condition or results of operations.

PROPRIETARY RIGHTS.  The Company relies on a combination of trade secrets, 
copyright and trademark laws, nondisclosure and other contractual provisions to 
protect its proprietary rights.  The Company currently has no patents covering 
its technology and it has not registered any of its trademarks. There can be no 
assurance that measures taken by the Company to protect its intellectual 
property will be adequate or that the Company's competitors will not 
independently develop systems and services that are substantially equivalent or 
superior to those of the Company. Substantial litigation regarding intellectual 
property rights exists in the software industry, and the Company expects that 
software products may be increasingly subject to third party infringement 
claims as the number of competitors in the Company's industry segment grows and 
the functionality of systems overlap. Although the Company believes that its 
systems and applications do not infringe upon the proprietary rights of third 
parties, there can be no assurance that third parties will not assert 
infringement claims against the Company in the future, that the Company would 
prevail in any such dispute or that a license or similar agreement will be 
available on reasonable terms in the event of an unfavorable ruling on any such 
claim. In addition, any such claim may require the Company to incur substantial 
litigation expenses or subject the Company to significant liabilities and could 
have a material adverse effect on the Company's business, financial condition 
and results of operations.

CUSTOMER CONCENTRATION; RELIANCE ON OEMS.  A significant portion of the 
Company's net sales is derived from a small number of customers.  For the 
period indicated, each of the following customers accounted for more than 10% 
of the Company's revenues:  in 1994, E-Med, Kodak, CEMAX and Agfa; and in 1995, 
E-Med, Kodak and CEMAX.  In 1996, Symphony Mobilex, Kodak, E-Med and CEMAX also 
accounted for a significant portion of the Company's net sales although none 
accounted for more than 10%.  Large customers also accounted for a significant 
portion of the Company's backlog at December 31, 1996.  The Company expects to 
continue to depend upon its principal customers for a significant portion of 
its sales, although there can be no assurance that the Company's principal 
customers will continue to purchase products and services from the Company at 
current levels, if at all.  The loss of one or more major customers or a change 
in their buying patterns could have a material adverse effect on the Company's 
business and results of operations.

SINGLE-SOURCE SUPPLIERS.  The Company purchases industry-standard parts and 
components for the assembly of its products, generally from multiple vendors.  
Although the Company relies on single-source suppliers for certain components, 
such as lasers, photomultiplier tubes and certain electronic components 
primarily to control price and quality, the Company believes that alternate 
sources of supply are available from other vendors for such components and has 
qualified second source suppliers for some, but not all, single-sourced parts. 
 The Company maintains good relationships with its vendors and, to date, has 
not experienced any material supply problems.  While the Company seeks to 
maintain an adequate inventory of single-sourced components there can be no 
assurance that such inventories will be sufficient or that delays in part or 
component deliveries will not occur in the future, which could result in delays 
or reductions in product shipments.  Furthermore, even if currently single-
sourced components could be replaced by other qualified parts, product redesign 
and testing could be costly and time consuming.  These factors could have a 
material adverse effect on the Company's business, financial condition and 
results of operations.

GOVERNMENT REGULATION.  The manufacturing and marketing of the Company's 
digitizers are subject to extensive government regulation in the United States 
and in other countries, and the process of obtaining and maintaining required 
regulatory approvals is lengthy, expensive and uncertain.  If a medical device 
manufacturer can establish that a newly developed device is "substantially 
equivalent" to a device that was legally marketed prior to May 1976, the date 
on which the Medical Device Amendments of 1976 were enacted, or to a device the 
Food and Drug Administration ("FDA") found to be substantially equivalent to a 
legally marketed pre-1976 device, the manufacturer may seek marketing clearance 
from the FDA to market the device by filing a 510(k) premarket notification.  
The 510(k) premarket notification must be supported by appropriate data 
establishing the claim of substantial equivalence to the satisfaction of the 
FDA.  Receipt of 510(k) clearance normally takes at least three months, but may 
take much longer and may require the submission of clinical safety and efficacy 
data to the FDA.  All of the Company's laser-based film digitizers, the CCD 
based film digitizer and the QR2000 software products that are commercially 
available have received 510(k) clearance.  There can be no assurance that 
510(k) clearance for any future product or any modification of an existing 
product will be granted, or that the process will not be unduly lengthy.  In 
the future, the FDA may require manufacturers of certain medical devices to 
engage in a more thorough and time consuming approval process than the 510(k) 
process, which could have a material adverse effect on the Company's business 
and results of operations.

The Company is also required to register as a Class II medical device 
manufacturer with the FDA and state agencies, such as the California Department 
of Health Services ("CDHS").  As such, the Company may be inspected on a 
routine basis by both the FDA and the CDHS for compliance with the FDA's GMP 
and other applicable regulations.  These regulations require that the Company 
manufacture its products and maintain its documents in a prescribed manner with 
respect to manufacturing, reporting of product malfunctions and other matters. 
 If the FDA believes that a company is not in compliance with federal 
regulatory requirements, it can institute proceedings to detain or seize 
products, issue a recall, prohibit marketing and sales of the company's 
products and assess civil and criminal penalties against the company, its 
officers or its employees.  Failure to comply with the regulatory requirements 
could have a material adverse effect on the Company's business and results of 
operations.  The Company was inspected by the FDA in 1996 and was found to be 
compliant with the FDA's GMP regulations but has not been inspected by CDHS to 
date.

The Company also relies on 510(k) pre-market notification for its current 
internally developed products. Additionally, the Company relies on 510(k) 
clearance and the finding by the FDA of substantial equivalence for the Image 
Management System ("IMS") and the Film Image ScanSoftware ("FISS") technologies 
acquired from Star Technologies, Inc. in July 1997. However, the Company 
believes that its success depends upon commercial sales of new versions of its 
medical image management software which may be subject to clearance or approval 
from the FDA and its foreign counterparts. There can be no assurance that a 
similar 510(k) clearance for any future product or enhancement of an existing 
product will be granted or that the process will not be lengthy. If the Company 
cannot establish that a product is "substantially equivalent" to certain 
legally marketed devices, the 510(k) clearance procedure may be unavailable and 
the Company may be required to utilize the longer and more expensive PMA 
process. Failure to receive or delays in receipt of FDA clearances or 
approvals, including the need for additional data as a prerequisite to 
clearance or approval, could have a material adverse effect on the Company's 
business, operating results and financial condition.

Sales of the Company's products outside the United States are subject to 
foreign regulatory requirements that vary from country to country. Additional 
approvals from foreign regulatory authorities may be required, and there can be 
no assurance that the Company will be able to obtain foreign approvals on a 
timely basis or at all, or that it will not be required to incur significant 
costs in obtaining or maintaining its foreign regulatory approvals. In Europe, 
the Company will be required to obtain certifications necessary to enable the 
"CE" mark to be affixed to the Company's products by mid 1998 to continue 
commercial sales in member countries of the European Union. The CE mark is an 
international symbol of quality and complies with applicable European medical 
device directives. The Company has not obtained such certifications, and there 
can be no assurance it will be able to obtain such certifications or any other 
international regulatory approvals in a timely manner, or at all. Failure to 
comply with foreign regulatory requirements could have a material adverse 
effect on the Company's business, financial condition and results of 
operations.

LITIGATION.  On July 9, 1997 and July 10, 1997, two class action complaints 
were filed in the Superior Court of the State of California, County of Santa 
Clara, and the U.S. District Court for the Northern District of California, 
respectively, against the Company, several of its current and former officers 
and directors, and its underwriters.  The complaints are brought on behalf of 
all persons who purchased the Company Common Stock during the putative class 
periods, November 15, 1995 to July 11, 1996.  The complaints allege that, 
during the class period, defendants made material misstatements and omitted to 
disclose material information concerning the Company's actual and expected 
performance and results, causing the price of the Company Common Stock to be 
artificially inflated.  The federal complaint alleges claims under Sections 
10(b) and 20(a) of the Exchange Act, and SEC Rule 10b-5 promulgated thereunder; 
the state complaint alleges claims under California state law.  Neither the 
federal nor the state complaint specifies the amount of damages sought.  The 
Company and the other defendants vigorously deny all allegations of wrongdoing, 
and intend to defend themselves aggressively.  On September 19, 1997, 
defendants filed a motion to dismiss the federal complaint.  On October 10, 
1997, defendants filed demurrers to the state complaint.  There can be no 
assurance that the Company will prevail in this action or that the plaintiffs 
will not recover damages.

THIRD-PARTY REIMBURSEMENT.  Third-party payers, such as governmental programs 
and private insurance plans, can indirectly affect the pricing or the relative 
attractiveness of the Company's products by regulating the maximum amount of 
reimbursement that they will provide for the taking, storing and interpretation 
of medical images. In recent years, healthcare costs have risen substantially, 
and third-party payers have come under increasing pressure to reduce such 
costs.  In this regard, extensive studies undertaken by the Clinton 
Administration, even though not successfully translated into regulatory action, 
have stimulated widespread analysis and reaction in the private sector focused 
on healthcare cost reductions, which may involve reductions in reimbursement 
rates in radiology.  A decrease in the reimbursement amounts for radiological 
procedures may decrease the amount which physicians, clinics and hospitals are 
able to charge patients for such services.  As a result, adoption of 
teleradiology and PACS may slow as capital investment budgets are reduced, and 
the demand for the Company's products could be significantly reduced.

PRODUCT LIABILITY AND INSURANCE.  The manufacture and sale of medical products 
entails significant risk of product liability claims.  While the Company 
believes that its current insurance coverage is appropriate, there can be no 
assurance that such coverage is adequate to protect the Company from any 
liabilities it might incur in connection with the sale of the Company's 
products.  In addition, the Company may require increased product liability 
coverage as additional products are commercialized.  Such insurance is 
expensive and in the future may not be available on acceptable terms, if at 
all.  A successful product liability claim or series of claims brought against 
the Company in excess of its insurance coverage could have a material adverse 
effect on the Company's business and results of operations.

VOLATILITY OF STOCK PRICES.  The market price of the Company's Common Stock has 
been and may continue to be volatile.  This volatility may result from a number 
of factors, including fluctuations in the Company's quarterly revenues and net 
income, announcements of technical innovations or new commercial products by 
the Company or its competitors, and conditions in the  market for medical image 
digitizers and the teleradiology and health care industry and for medical image 
management products and healthcare information systems and services.  Also, the 
stock market has experienced and continues to experience extreme price and 
volume fluctuations which have affected the market prices of securities, 
particularly those of medical technology companies, and which often have been 
unrelated to the operating performance of the companies.  These broad market 
fluctuations, as well as general economic and political conditions, may 
adversely affect the market price of the Company's Common Stock in future 
periods.



                               SELLING STOCKHOLDERS

The following table shows the names of the Selling Stockholders and the number 
of Shares to be sold by them pursuant to this Prospectus:

                     Name                                  Number of Shares	
- ----------------------------------------------------       ----------------
Certain unnamed non-affiliates of the Company(1)....             2,515

(1)  Each unnamed non-affiliate holds up to or less than 1,000 shares of the 
Shares and may use this reoffer prospectus to sell up to the number of shares 
such non-affiliate currently holds.


                               PLAN OF DISTRIBUTION

The Company has been advised by the Selling Stockholders that they intend to 
sell all or a portion of the shares offered hereby from time to time on The 
Nasdaq National Market or in the over-the-counter market and that sales will be 
made at prices prevailing at the times of such sales. The Selling Stockholders 
may also make private sales directly or through a broker or brokers, who may 
act as agent or as principal. In connection with any sales, the Selling 
Stockholders and any brokers participating in such sales may be deemed to be 
underwriters within the meaning of the Securities Act.

Any broker-dealer participating in such transactions as agent may receive 
commissions from the Selling Stockholders (and, if such broker acts as agent 
for the purchaser of such shares, from such purchaser). Usual and customary 
brokerage fees will be paid by the Selling Stockholders. Broker-dealers may 
agree with the Selling Stockholders to sell a specified number of shares at a 
stipulated price per share, and, to the extent such a broker-dealer is unable 
to do so acting as agent for the Selling Stockholders, to purchase as principal 
any unsold shares at the price required to fulfill the broker-dealer commitment 
to the Selling Stockholders. Broker-dealers who acquire shares as principal may 
thereafter resell such shares from time to time in transactions (which may 
involve crosses and block transactions and which may involve sales to and 
through other broker-dealers, including transactions of the nature described 
above) in the over-the-counter market, in negotiated transactions or otherwise 
at market prices prevailing at the time of sale or at negotiated prices, and in 
connection with such resales may pay to or receive from the purchasers of such 
shares commissions computed as described above.

The Company has advised the Selling Stockholders that Regulation M promulgated 
under the Exchange Act may apply to sales in the market, has furnished the 
Selling Stockholders with a copy of this Regulation and has informed them of 
the need for delivery of copies of this Prospectus. The Selling Stockholders 
may indemnify any broker-dealer that participates in transactions involving the 
sale of the shares against certain liabilities, including liabilities arising 
under the Securities Act. Any commissions paid or any discounts or concessions 
allowed to any such broker-dealers, and, if any such broker-dealers purchase 
shares as principal, any profits received on the resale of such shares, may be 
deemed to be underwriting discounts and commissions under the Securities Act.

Upon the Company's being notified by the Selling Stockholders that any material 
arrangement has been entered into with a broker-dealer for the sale of shares 
through a cross or block trade, the Company may, in its discretion, file a 
supplemental prospectus under Rule 424(c) under the Securities Act, setting 
forth the name of the participating broker-dealer(s), the number of shares 
involved, the price at which such shares were sold by the Selling Stockholders, 
the commissions paid or discounts or concessions allowed by the Selling 
Stockholders to such broker-dealer(s), and where applicable, that such 
broker-dealer(s) did not conduct any investigation to verify the information 
set out in this Prospectus.

Any securities covered by this Prospectus which qualify for sale pursuant to 
Rule 144 under the Securities Act may be sold under that Rule rather than 
pursuant to this Prospectus.

There can be no assurances that the Selling Stockholders will sell any or all 
of the shares of Common Stock offered hereunder.

                           SECURITIES TO BE OFFERED

The Shares offered hereby are shares of Common Stock, $.001 par value, of the 
Company. 

COMPANY COMMON STOCK.  Holders of Company Common Stock are entitled to one vote 
per share on all matters to be voted upon by the stockholders.  The holders of 
Company Common Stock are entitled to receive ratably such dividends, if any, as 
may be declared from time to time by the Company's Board of Directors (the 
"Company Board") out of funds legally available therefor.  In the event of a 
liquidation, dissolution or winding up of the Company, the holders of Company 
Common Stock are entitled to share ratably in all assets remaining after 
payment of liabilities and the liquidiation preference, if any, of any 
outstanding shares of Company Preferred Stock.  There are no redemption or 
sinking fund provisions applicable to the Company Common Stock.  All 
outstanding shares of Company Common Stock are fully paid and non-assessable.

COMPANY PREFERRED STOCK.  The Company Board has the authority to issue up to 
5,000,000 shares of Company Preferred Stock in one or more series and to fix 
the rights, preferences, privileges and restrictions granted to or imposed on 
any unissued and undesignated shares of Company Preferred Stock and to fix the 
number of shares constituting a series and the designations of such series, 
without any further vote or action by the stockholders.  Although it presently 
has no intention to do so, the Company Board, without stockholder approval, can 
issue Company Preferred Stock with voting and conversion rights which could 
adversely affect the voting power or other rights of the holders of Company 
Common Stock.  The issuance of Company Preferred Stock may have the effect of 
delaying, deferring or preventing a change in control of the Company.  The 
Company has no present plans to issue Company Preferred Stock.

REGISTRATION RIGHTS.  Pursuant to an agreement between the Company and a small 
number of holders (or their permitted transferees) ("Holders") of a limited 
amount of Company Common Stock, the Holders are entitled to certain rights with 
respect to the registration of such shares under the Securities Act.  If the 
Company proposes to register any of its securities under the Securities Act, 
either for its own account or for the account of other security holders, the 
Holders are entitled to notice of the registration and are entitled to include, 
at the Company's expense, such shares therein, provided, among other 
conditions, that the underwriters have the right to limit the number of such 
shares included in the registration.  In addition, certain of the Holders may 
require the Company at its expense on not more than two occasions, to file a 
registration statement under the Securities Act with respect to their shares of 
Company Common Stock, and the Company is required to use its best efforts to 
effect the registration, subject to certain restrictions and limitations.  
Further, certain of the Holders may require the Company, at its expense, to 
register their shares on a Registration Statement on Form S-3 when such form 
becomes available to the Company, subject to certain conditions and 
limitations.

Item 5.  Interests of Named Experts and Counsel

The validity of the shares of Common Stock offered hereby will be passed upon 
for the Company by Cooley Godward LLP, Palo Alto, California.  Andrei M. 
Manoliu, Ph.D., a partner of Cooley Godward LLP, is the Secretary of the 
Company.


Item 6.  Indemnification of Directors and Officers

Under Section 145 of the Delaware General Corporation Law, the Company has 
broad powers to indemnify its directors and officers against liabilities they 
may incur in such capacities, including liabilities under the Act.  The 
Company's Bylaws also 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's Certificate of Incorporation provides for the elimination of 
liability for monetary damages for breach of the directors' fiduciary duty of 
care to the Company 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 
Company, 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.

The Company has entered into agreements with its directors and executive 
officers that require the Company to indemnify such persons against expenses, 
judgments, fines, settlements and other amounts actually and reasonably 
incurred (including expenses of a derivative action) in connection with any 
proceeding, whether actual or threatened, to which any such person may be made 
a party by reason of the fact that such person is or was a director or officer 
of the Company or any of its affiliated enterprises, provided such person acted 
in good faith and in a manner such person reasonably believed to be in or not 
opposed to be best interests of the Company and, with respect to any criminal 
proceeding, had no reasonable cause to believe his or her conduct was unlawful. 
 The indemnification agreements also set forth certain procedures that will 
apply in the event of a claim for indemnification thereunder.

Item 7.  Exemption from Registration Claimed

The 2515 shares to be reoffered or resold pursuant to this Registration 
Statement (the "Securities"), were issued in a transaction exempt from 
registration pursuant to Section 4(2) of the Securities Act, based on the 
following facts:  such shares were issued only to twelve persons who (i) 
acquired such shares for investment purposes only (ii) are or had been 
employees of CompuRAD, a wholly owned subsidiary of the Company, holding 
positions in CompuRAD such as midlevel salespersons, administrators and 
engineers and (iii) based on their employment with CompuRAD and their past 
experience, had sufficient knowledge and experience in financial and business 
matters that they were capable of evaluating the merits and risks of the 
investment.

The Securities were issued when securities of CompuRAD were converted by 
operation of law into Company Common Stock pursuant to the terms of an 
Agreement and Plan of Merger and Reorganization entered into by the Company and 
CompuRAD (pursuant to which a wholly owned subsidiary of the Company merged 
with and into CompuRAD and CompuRAD became a wholly owned subsidiary of the 
Company (the "Merger")).  The CompuRAD securities originally issued to the 
holders of the Securities were issued immediately prior to the consummation of 
the Merger under the terms of an employee stock purchase plan of CompuRAD.  
These securities were not, therefore, outstanding on the record date for the 
CompuRAD stockholder vote on the Merger and holders of such securities could 
not vote them in connection with the Merger.

Item 9.  Undertakings

The undersigned registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-
effective amendment to this registration statement:

   (i)  To include any prospectus required by Section 10(a)(3) of the 
        Securities Act;

   (ii) To reflect in the prospectus any facts or events arising after the
        effective date of the registration statement (or the most recent post-
        effective amendment thereof) which, individually or in the aggregate, 
        represent a fundamental change in the information set forth in the 
        registration statement.  Notwithstanding the foregoing, any increase or 
        decrease in volume of securities offered (if the total dollar value of 
        securities offered would not exceed that which was registered) and any 
        deviation from the low or high end of the estimated maximum offering 
        range may be reflected in the form of prospectus filed with the 
        commission pursuant to Rule 424(b) (section  230.424(b) of this 
        chapter) if, in the aggregate, the changes in volume and price
        represent no more than a 20% change in the maximum aggregate offering 
        price set forth in the "Calculation of Registration Fee" table in the 
        effective registration statement.

   (iii)To include any material information with respect to the plan of 
        distribution not previously disclosed in the registration statement or 
        any material change to such information in the registration statement;
 
   
PROVIDED, HOWEVER, that paragraphs (a)(i) and (a)(ii) do not apply if the 
registration statement is on Form S-3 or Form S-8 and the information required 
to be included in a post-effective amendment by those paragraphs is contained 
in periodic reports filed by the issuer pursuant to Section 13 or Section 15(d) 
of the Exchange Act that are incorporated by reference in the registration 
statement.

That, for the purpose of determining any liability under the Securities Act, 
each such post-effective amendment shall be deemed to be a new registration 
statement relating to the securities offered herein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

To remove from registration by means of a post-effective amendment any of the 
securities being registered which remain unsold at the termination of the 
offering.

The undersigned registrant hereby undertakes that, for purposes of determining 
any liability under the Securities Act, each filing of the registrant's annual 
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, 
where applicable, each filing of an employee benefit plan's annual report 
pursuant to Section 15(d) of the Exchange Act) that is incorporated by 
reference in the Registration Statement shall be deemed to be a new 
registration statement relating to the securities offered herein, and the 
offering of such securities at that time shall be deemed to be the initial bona 
fide offering thereof.

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 6 above, or otherwise, the 
registrant has been advised that in the opinion of the Securities and Exchange 
Commission such indemnification is against public policy as expressed in the 
Securities Act and is, therefore, unenforceable.  In the event that a claim for 
indemnification against such liabilities (other than the payment by the 
registrant of expenses incurred or paid by a director, officer or controlling 
person of the registrant in the successful defense of any action, suit or 
proceeding) is asserted by such director, officer or controlling person in 
connection with the securities being registered, 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.


                               SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, the 
Registrant certifies that it has reasonable grounds to believe that it meets 
all of the requirements for filing on Form S-8 and has duly caused this 
Registration Statement to be signed on its behalf by the undersigned, 
thereunto duly authorized, in the City of Sunnyvale, State of California, on 
December 12, 1997.

Lumisys Incorporated
225 Humboldt Court
Sunnyvale, CA 94089

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection 
with the filing by Lumisys Incorporated (the "Company") of a Registration 
Statement on Form S-8 and Form S-3 on or about December 11, 1997 (the 
"Registration Statement") with the Securities and Exchange Commission covering 
the offering of up to four hundred four thousand two hundred seventy five 
(402,275) shares of the Company's Common Stock, $.001 par value per share (i) 
issuable upon exercise of options originally granted by CompuRAD, Inc., a 
wholly-owned subsidiary of the Company, under its 1996 Stock Plan and Stock 
Option Plan (the "Plans")(the "Option Shares"), and (ii) issued pursuant to the 
CompuRAD Employee Stock Purchase Plan (the "Stock Purchase Shares").

In connection with this opinion, we have examined the Registration Statement, 
your Certificate of Incorporation and Bylaws, as amended, and such other 
documents, records, certificates, memoranda and other instruments as we deem 
necessary as a basis for this opinion.  We have assumed the genuineness and 
authenticity of all documents submitted to us as originals, the conformity to 
originals of all documents submitted to us as copies thereof, and the due 
execution and delivery of all documents where due execution and delivery are a 
prerequisite to the effectiveness thereof.

On the basis of the foregoing, and in reliance thereon, we are of the opinion 
that the Option Shares, when sold and issued in accordance with the Plans and 
the Registration Statement, will be, and the Stock Purchase Shares are, validly 
issued, fully  paid, and nonassessable.

We consent to the filing of this opinion as an exhibit to the Registration 
Statement.

Very truly yours,

Cooley Godward LLP



Andrei M. Manoliu

 EXHIBIT 99.1
                               COMPURAD, INC.
                              1996 STOCK PLAN


1.  PURPOSES OF THE PLAN.  The purposes of this Stock Plan are:

  -  to attract and retain the best available personnel for positions of 
substantial responsibility, 

  -  to provide additional incentive to Employees, Directors and Consultants, 
and 

  -  to promote the success of the Company's business.  

Options granted under the Plan may be Incentive Stock Options or Nonstatutory 
Stock Options, as determined by the Administrator at the time of grant.  Stock 
Purchase Rights may also be granted under the Plan.

2.  DEFINITIONS.  As used herein, the following definitions shall apply:

a.  "Administrator" means the Board or any of its Committees as shall be 
administering the Plan, in accordance with Section 4 of the Plan.

b.  "Applicable Laws" means the requirements relating to the administration of 
stock option plans under U. S. state corporate laws, U.S. federal and state 
securities laws, the Code, any stock exchange or quotation system on which the 
Common Stock is listed or quoted and the applicable laws of any foreign 
country or jurisdiction where Options or Stock Purchase Rights are, or will 
be, granted under the Plan.

c.  "Board" means the Board of Directors of the Company.

d.  "Code" means the Internal Revenue Code of 1986, as amended.

between the Company, its Parent, any Subsidiary, or any successor.  For 
purposes of Incentive Stock Options, no such leave may exceed ninety days, 
unless reemployment upon expiration of such leave is guaranteed by statute or 
contract.  If reemployment upon expiration of a leave of absence approved by 
the Company is not so guaranteed, on the 181st day of such leave any Incentive 
Stock Option held by the Optionee shall cease to be treated as an Incentive 
Stock Option and shall be treated for tax purposes as a Nonstatutory Stock 
Option.  Neither service as a Director nor payment of a director's fee by the 
Company shall be sufficient to constitute "employment" by the Company.

l.  "Exchange Act" means the Securities Exchange Act of 1934, as amended.

m.  "Fair Market Value" means, as of any date, the value of Common Stock 
determined as follows:

     -  If the Common Stock is listed on any established stock exchange or a 
national market system, including without limitation the Nasdaq National

Market Value shall be the closing sales price for such stock (or the closing 
bid, if no sales were reported) as quoted on such exchange or system for the 
last market trading day prior to the time of determination, as reported in The 
Wall Street Journal or such other source as the Administrator deems reliable;

     -  If the Common Stock is regularly quoted by a recognized securities 
dealer but selling prices are not reported, the Fair Market Value of a Share 
of Common Stock shall be the mean between the high bid and low asked prices 
for the Common Stock on the last market trading day prior to the day of 
determination, as reported in The Wall Street Journal or such other source as 
the Administrator deems reliable;

     -  In the absence of an established market for the Common Stock, the Fair 
Market Value shall be determined in good faith by the Administrator.

grant of Stock Purchase Rights under Section 11 below.

z.  "Restricted Stock Purchase Agreement" means a written agreement between 
the Company and the Optionee evidencing the terms and restrictions applying to 
stock purchased under a Stock Purchase Right.  The Restricted Stock Purchase 
Agreement is subject to the terms and conditions of the Plan and the Notice of 
Grant.

aa.  "Rule 16b-3" means Rule 16b-3 of the Exchange Act or any successor to 
Rule 16b-3, as in effect when discretion is being exercised with respect to

3.  Stock Subject to the Plan.  Subject to the provisions of Section 13 of the 
Plan, the maximum aggregate number of Shares which may be optioned and sold 
under the Plan is 400,000 Shares.  The Shares may be authorized, but unissued, 
or reacquired Common Stock.  

If an Option or Stock Purchase Right expires or becomes unexercisable without 
having been exercised in full, or is surrendered pursuant to an Option 
Exchange Program, the unpurchased Shares which were subject thereto shall 
become available for future grant or sale under the Plan (unless the Plan has 
terminated); provided, however, that Shares that have actually been issued 
under the Plan, whether upon exercise of an Option or Right, shall not be 
returned to the Plan and shall not become available for future distribution 
under the Plan, except that if Shares of Restricted Stock are repurchased by 
the Company at their original purchase price, such Shares shall become 
available for future grant under the Plan. 

4.  Administration of the Plan.

a.  Procedure.

     -  Multiple Administrative Bodies.  The Plan may be administered by 
different Committees with respect to different groups of Service Providers.

     - Section 162(m).  To the extent that the Administrator determines it to 
be desirable to qualify Options granted hereunder as "performance-based 
compensation" within the meaning of Section 162(m) of the Code, the Plan shall 
be administered by a Committee of two or more "outside directors" within the 
meaning of Section 162(m) of the Code.

     -  Rule 16b-3.  To the extent desirable to qualify transactions hereunder 
as exempt under Rule 16b-3, the transactions contemplated hereunder shall be 
structured to satisfy the requirements for exemption under Rule 16b-3.

      -  Other Administration.  Other than as provided above, the Plan shall 
be administered by (A) the Board or (B) a Committee, which committee shall be 
constituted to satisfy Applicable Laws. 

b.  Powers of the Administrator.  Subject to the provisions of the Plan, and 
in the case of a Committee, subject to the specific duties delegated by the 
Board to such Committee, the Administrator shall have the authority, in its 
discretion:

     -  to determine the Fair Market Value;

     -  to select the Service Providers to whom Options and Stock Purchase 
Rights may be granted hereunder;

     -  to determine the number of shares of Common Stock to be covered by 
each Option and Stock Purchase Right granted hereunder;

     -  to approve forms of agreement for use under the Plan;

     -  to determine the terms and conditions, not inconsistent with the terms 
of the Plan, of any Option or Stock Purchase Right granted hereunder.  Such 
terms and conditions include, but are not limited to, the exercise price, the 
time or times when Options or Stock Purchase Rights may be exercised (which 
may be based on performance criteria), any vesting acceleration or waiver of 
forfeiture restrictions, and any restriction or limitation regarding any 
Option or Stock Purchase Right or the shares of Common Stock relating thereto, 
based in each case on such factors as the Administrator, in its sole 
discretion, shall determine;

     -  to reduce the exercise price of any Option or Stock Purchase Right to 
the then current Fair Market Value if the Fair Market Value of the Common 
Stock covered by such Option or Stock Purchase Right shall have declined since 
the date the Option or Stock Purchase Right was granted;

     -  to institute an Option Exchange Program;

     -  to construe and interpret the terms of the Plan and awards granted 
pursuant to the Plan;

     -  to prescribe, amend and rescind rules and regulations relating to the 
Plan, including rules and regulations relating to sub-plans established for 
the purpose of qualifying for preferred tax treatment under foreign tax laws;

     -  to modify or amend each Option or Stock Purchase Right (subject to 
Section 15(c) of the Plan), including the discretionary authority to extend 
the post-termination exercisability period of Options longer than is otherwise 
provided for in the Plan;

     -  to allow Optionees to satisfy withholding tax obligations by electing 
to have the Company withhold from the Shares to be issued upon exercise of an 
Option or Stock Purchase Right that number of Shares having a Fair Market 
Value equal to the amount required to be withheld.  The Fair Market Value of 
the Shares to be withheld shall be determined on the date that the amount of 
tax to be withheld is to be determined.  All elections by an Optionee to have 
Shares withheld for this purpose shall be made in such form and under such 
conditions as the Administrator may deem necessary or advisable;

     -  to authorize any person to execute on behalf of the Company any 
instrument required to effect the grant of an Option or Stock Purchase Right 
previously granted by the Administrator;

     -  to make all other determinations deemed necessary or advisable for 
administering the Plan.

c.  Effect of Administrator's Decision.  The Administrator's decisions, 
determinations and interpretations shall be final and binding on all Optionees 
and any other holders of Options or Stock Purchase Rights.

5.  Eligibility.  Nonstatutory Stock Options and Stock Purchase Rights may be 
granted to Service Providers.  Incentive Stock Options may be granted only to 
Employees.

6.  Limitations.

a.  Each Option shall be designated in the Option Agreement as either an 
Incentive Stock Option or a Nonstatutory Stock Option.  However, 
notwithstanding such designation, to the extent that the aggregate Fair Market 
Value of the Shares with respect to which Incentive Stock Options are 
exercisable for the first time by the Optionee during any calendar year (under 
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such 
Options shall be treated as Nonstatutory Stock Options.  For purposes of this 
Section 6(a), Incentive Stock Options shall be taken into account in the order 
in which they were granted.  The Fair Market Value of the Shares shall be 
determined as of the time the Option with respect to such Shares is granted.

b.  Neither the Plan nor any Option or Stock Purchase Right shall confer upon 
an Optionee any right with respect to continuing the Optionee's relationship 
as a Service Provider with the Company, nor shall they interfere in any way 
with the Optionee's right or the Company's right to terminate such 
relationship at any time, with or without cause.

c.  The following limitations shall apply to grants of Options:

     -  No Service Provider shall be granted, in any fiscal year of the 
Company, Options to purchase more than 200,000 Shares.

     -  In connection with his or her initial service, a Service Provider may 
be granted Options to purchase up to an additional 150,000 Shares which shall 
not count against the limit set forth in subsection (i) above.

     -  The foregoing limitations shall be adjusted proportionately in 
connection with any change in the Company's capitalization as described in 
Section 13. 

     -  If an Option is cancelled in the same fiscal year of the Company in 
which it was granted (other than in connection with a transaction described in 
Section 13), the cancelled Option will be counted against the limits set forth 
in subsections (i) and (ii) above.  For this purpose, if the exercise price of 
an Option is reduced, the transaction will be treated as a cancellation of the 
Option and the grant of a new Option.

7.  Term of Plan.  Subject to Section 19 of the Plan, the Plan shall become 
effective upon its adoption by the Board.  It shall continue in effect for a 
term of ten (10) years unless terminated earlier under Section 15 of the Plan.

8.  Term of Option.  The term of each Option shall be stated in the Option 
Agreement.  In the case of an Incentive Stock Option, the term shall be 
ten (10) years from the date of grant or such shorter term as may be provided 
in the Option Agreement.  Moreover, in the case of an Incentive Stock Option 
granted to an Optionee who, at the time the Incentive Stock Option is granted, 
owns stock representing more than ten percent (10%) of the voting power of all 
classes of stock of the Company or any Parent or Subsidiary, the term of the 
Incentive Stock Option shall be five (5) years from the date of grant or such 
shorter term as may be provided in the Option Agreement.

9.  Option Exercise Price and Consideration.

a.  Exercise Price.  The per share exercise price for the Shares to be issued 
pursuant to exercise of an Option shall be determined by the Administrator, 
subject to the following:

     -  In the case of an Incentive Stock Option

         A.  granted to an Employee who, at the time the Incentive Stock 
Option is granted, owns stock representing more than ten percent (10%) of the 
voting power of all classes of stock of the Company or any Parent or 
Subsidiary, the per Share exercise price shall be no less than 110% of the 
Fair Market Value per Share on the date of grant.

         B.  granted to any Employee other than an Employee described in 
paragraph (A) immediately above, the per Share exercise price shall be no less 
than 100% of the Fair Market Value per Share on the date of grant.

     -  In the case of a Nonstatutory Stock Option, the per Share exercise 
price shall be determined by the Administrator.  In the case of a Nonstatutory 
Stock Option intended to qualify as "performance-based compensation" within 
the meaning of Section 162(m) of the Code, the per Share exercise price shall 
be no less than 100% of the Fair Market Value per Share on the date of grant.

     -  Notwithstanding the foregoing, Options may be granted with a per Share 
exercise price of less than 100% of the Fair Market Value per Share on the 
date of grant pursuant to a merger or other corporate transaction.

b.  Waiting Period and Exercise Dates.  At the time an Option is granted, the 
Administrator shall fix the period within which the Option may be exercised 
and shall determine any conditions which must be satisfied before the Option 
may be exercised. 

c.  Form of Consideration.  The Administrator shall determine the acceptable 
form of consideration for exercising an Option, including the method of 
payment.  In the case of an Incentive Stock Option, the Administrator shall 
determine the acceptable form of consideration at the time of grant.  Such 
consideration may consist entirely of:

     -  cash;

     -  check;

     -  promissory note;

     -  other Shares which (A) in the case of Shares acquired upon exercise of 
an option, have been owned by the Optionee for more than six months on the 
date of surrender, and (B) have a Fair Market Value on the date of surrender 
equal to the aggregate exercise price of the Shares as to which said Option 
shall be exercised;

     -  consideration received by the Company under a cashless exercise 
program implemented by the Company in connection with the Plan;

     -  a reduction in the amount of any Company liability to the Optionee, 
including any liability attributable to the Optionee's participation in any 
Company-sponsored deferred compensation program or arrangement;

     -  any combination of the foregoing methods of payment; or

     -  such other consideration and method of payment for the issuance of 
Shares to the extent permitted by Applicable Laws.

10. Exercise of Option.

a.  Procedure for Exercise; Rights as a Shareholder. Any Option granted 
hereunder shall be exercisable according to the terms of the Plan and at such 
times and under such conditions as determined by the Administrator and set 
forth in the Option Agreement.  Unless the Administrator provides otherwise, 
vesting of Options granted hereunder shall be tolled during any unpaid leave 
of absence.  An Option may not be exercised for a fraction of a Share.

An Option shall be deemed exercised when the Company receives: (i) written or 
electronic notice of exercise (in accordance with the Option Agreement) from 
the person entitled to exercise the Option, and (ii) full payment for the 
Shares with respect to which the Option is exercised.  Full payment may 
consist of any consideration and method of payment authorized by the 
Administrator and permitted by the Option Agreement and the Plan.  Shares 
issued upon exercise of an Option shall be issued in the name of the Optionee 
or, if requested by the Optionee, in the name of the Optionee and his or her 
spouse.  Until the Shares are issued (as evidenced by the appropriate entry on 
the books of the Company or of a duly authorized transfer agent of the 
Company), no right to vote or receive dividends or any other rights as a 
shareholder shall exist with respect to the Optioned Stock, notwithstanding 
the exercise of the Option.  The Company shall issue (or cause to be issued) 
such Shares promptly after the Option is exercised.  No adjustment will be 
made for a dividend or other right for which the record date is prior to the 
date the Shares are issued, except as provided in Section 13 of the Plan.

Exercising an Option in any manner shall decrease the number of Shares 
thereafter available, both for purposes of the Plan and for sale under the 
Option, by the number of Shares as to which the Option is exercised.

b.  Termination of Relationship as a Service Provider.  If an Optionee ceases 
to be a Service Provider, other than upon the Optionee's death or Disability, 
the Optionee may exercise his or her Option within such period of time as is 
specified in the Option Agreement to the extent that the Option is vested on 
the date of termination (but in no event later than the expiration of the term 
of such Option as set forth in the Option Agreement).  In the absence of a 
specified time in the Option Agreement, the Option shall remain exercisable 
for three (3) months following the Optionee's termination.  If, on the date of 
termination, the Optionee is not vested as to his or her entire Option, the 
Shares covered by the unvested portion of the Option shall revert to the Plan. 
 If, after termination, the Optionee does not exercise his or her Option 
within the time specified by the Administrator, the Option shall terminate, 
and the Shares covered by such Option shall revert to the Plan.

c.  Disability of Optionee.  If an Optionee ceases to be a Service Provider as 
a result of the Optionee's Disability, the Optionee may exercise his or her 
Option within such period of time as is specified in the Option Agreement to 
the extent the Option is vested on the date of termination (but in no event 
later than the expiration of the term of such Option as set forth in the 
Option Agreement).  In the absence of a specified time in the Option 
Agreement, the Option shall remain exercisable for twelve (12) months 
following the Optionee's termination.  If, on the date of termination, the 
Optionee is not vested as to his or her entire Option, the Shares covered by 
the unvested portion of the Option shall revert to the Plan.  If, after 
termination, the Optionee does not exercise his or her Option within the time 
specified herein, the Option shall terminate, and the Shares covered by such 
Option shall revert to the Plan.

d.  Death of Optionee.  If an Optionee dies while a Service Provider, the 
Option may be exercised within such period of time as is specified in the 
Option Agreement (but in no event later than the expiration of the term of 
such Option as set forth in the Notice of Grant), by the Optionee's estate or 
by a person who acquires the right to exercise the Option by bequest or 
inheritance, but only to the extent that the Option is vested on the date of 
death.  In the absence of a specified time in the Option Agreement, the Option 
shall remain exercisable for twelve (12) months following the Optionee's 
termination.  If, at the time of death, the Optionee is not vested as to his 
or her entire Option, the Shares covered by the unvested portion of the Option 
shall immediately revert to the Plan.  The Option may be exercised by the 
executor or administrator of the Optionee's estate or, if none, by the 
person(s) entitled to exercise the Option under the Optionee's will or the 
laws of descent or distribution.  If the Option is not so exercised within the 
time specified herein, the Option shall terminate, and the Shares covered by 
such Option shall revert to the Plan.

e.  Buyout Provisions.  The Administrator may at any time offer to buy out for 
a payment in cash or Shares, an Option previously granted based on such terms 
and conditions as the Administrator shall establish and communicate to the 
Optionee at the time that such offer is made.

11. Stock Purchase Rights.

a.  Rights to Purchase.  Stock Purchase Rights may be issued either alone, in 
addition to, or in tandem with other awards granted under the Plan and/or cash 
awards made outside of the Plan.  After the Administrator determines that it 
will offer Stock Purchase Rights under the Plan, it shall advise the offeree 
in writing or electronically, by means of a Notice of Grant, of the terms, 
conditions and restrictions related to the offer, including the number of 
Shares that the offeree shall be entitled to purchase, the price to be paid, 
and the time within which the offeree must accept such offer.  The offer shall 
be accepted by execution of a Restricted Stock Purchase Agreement in the form 
determined by the Administrator.

b.  Repurchase Option.  Unless the Administrator determines otherwise, the 
Restricted Stock Purchase Agreement shall grant the Company a repurchase 
option exercisable upon the voluntary or involuntary termination of the 
purchaser's service with the Company for any reason (including death or 
Disability).  The purchase price for Shares repurchased pursuant to the 
Restricted Stock purchase agreement shall be the original price paid by the 
purchaser and may be paid by cancellation of any indebtedness of the purchaser 
to the Company.  The repurchase option shall lapse at a rate determined by the 
Administrator.

c.  Other Provisions.  The Restricted Stock Purchase Agreement shall contain 
such other terms, provisions and conditions not inconsistent with the Plan as 
may be determined by the Administrator in its sole discretion. 

d.  Rights as a Shareholder.  Once the Stock Purchase Right is exercised, the 
purchaser shall have the rights equivalent to those of a shareholder, and 
shall be a shareholder when his or her purchase is entered upon the records of 
the duly authorized transfer agent of the Company.  No adjustment will be made 
for a dividend or other right for which the record date is prior to the date 
the Stock Purchase Right is exercised, except as provided in Section 13 of the 
Plan.

12. Non-Transferability of Options and Stock Purchase Rights.  Unless 
determined otherwise by the Administrator, an Option or Stock Purchase Right 
may not be sold, pledged, assigned, hypothecated, transferred, or disposed of 
in any manner other than by will or by the laws of descent or distribution and 
may be exercised, during the lifetime of the Optionee, only by the Optionee.  
If the Administrator makes an Option or Stock Purchase Right transferable, 
such Option or Stock Purchase Right shall contain such additional terms and 
conditions as the Administrator deems appropriate.

13. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset 
Sale. 

a.  Changes in Capitalization.  Subject to any required action by the 
shareholders of the Company, the number of shares of Common Stock covered by 
each outstanding Option and Stock Purchase Right, and the number of shares of 
Common Stock which have been authorized for issuance under the Plan but as to 
which no Options or Stock Purchase Rights have yet been granted or which have 
been returned to the Plan upon cancellation or expiration of an Option or 
Stock Purchase Right, as well as the price per share of Common Stock covered 
by each such outstanding Option or Stock Purchase Right, shall be 
proportionately adjusted for any increase or decrease in the number of issued 
shares of Common Stock resulting from a stock split, reverse stock split, 
stock dividend, combination or reclassification of the Common Stock, or any 
other increase or decrease in the number of issued shares of Common Stock 
effected without receipt of consideration by the Company; provided, however, 
that conversion of any convertible securities of the Company shall not be 
deemed to have been "effected without receipt of consideration."  Such 
adjustment shall be made by the Board, whose determination in that respect 
shall be final, binding and conclusive.  Except as expressly provided herein, 
no issuance by the Company of shares of stock of any class, or securities 
convertible into shares of stock of any class, shall affect, and no adjustment 
by reason thereof shall be made with respect to, the number or price of shares 
of Common Stock subject to an Option or Stock Purchase Right.
b.  Dissolution or Liquidation.  In the event of the proposed dissolution or 
liquidation of the Company, the Administrator shall notify each Optionee as 
soon as practicable prior to the effective date of such proposed transaction. 
 The Administrator in its discretion may provide for an Optionee to have the 
right to exercise his or her Option until ten (10) days prior to such 
transaction as to all of the Optioned Stock covered thereby, including Shares 
as to which the Option would not otherwise be exercisable.  In addition, the 
Administrator may provide that any Company repurchase option applicable to any 
Shares purchased upon exercise of an Option or Stock Purchase Right shall 
lapse as to all such Shares, provided the proposed dissolution or liquidation 
takes place at the time and in the manner contemplated.  To the extent it has 
not been previously exercised, an Option or Stock Purchase Right will 
terminate immediately prior to the consummation of such proposed action.

c.  Merger or Asset Sale.  In the event of a merger of the Company with or 
into another corporation, or the sale of substantially all of the assets of 
the Company, each outstanding Option and Stock Purchase Right shall be assumed 
or an equivalent option or right substituted by the successor corporation or a 
Parent or Subsidiary of the successor corporation.  In the event that the 
successor corporation refuses to assume or substitute for the Option or Stock 
Purchase Right, the Optionee shall fully vest in and have the right to 
exercise the Option or Stock Purchase Right as to all of the Optioned Stock, 
including Shares as to which it would not otherwise be vested or exercisable. 
 If an Option or Stock Purchase Right becomes fully vested and exercisable in 
lieu of assumption or substitution in the event of a merger or sale of assets, 
the Administrator shall notify the Optionee in writing or electronically that 
the Option or Stock Purchase Right shall be fully vested and exercisable for a 
period of fifteen (15) days from the date of such notice, and the Option or 
Stock Purchase Right shall terminate upon the expiration of such period.  For 
the purposes of this paragraph, the Option or Stock Purchase Right shall be 
considered assumed if, following the merger or sale of assets, the option or 
right confers the right to purchase or receive, for each Share of Optioned 
Stock subject to the Option or Stock Purchase Right immediately prior to the 
merger or sale of assets, the consideration (whether stock, cash, or other 
securities or property) received in the merger or sale of assets by holders of 
Common Stock for each Share held on the effective date of the transaction (and 
if holders were offered a choice of consideration, the type of consideration 
chosen by the holders of a majority of the outstanding Shares); provided, 
however, that if such consideration received in the merger or sale of assets 
is not solely common stock of the successor corporation or its Parent, the 
Administrator may, with the consent of the successor corporation, provide for 
the consideration to be received upon the exercise of the Option or Stock 
Purchase Right, for each Share of Optioned Stock subject to the Option or 
Stock Purchase Right, to be solely common stock of the successor corporation 
or its Parent equal in fair market value to the per share consideration 
received by holders of Common Stock in the merger or sale of assets.

14. Date of Grant.  The date of grant of an Option or Stock Purchase Right 
shall be, for all purposes, the date on which the Administrator makes the 
determination granting such Option or Stock Purchase Right, or such other 
later date as is determined by the Administrator.  Notice of the determination 
shall be provided to each Optionee within a reasonable time after the date of 
such grant.

15. Amendment and Termination of the Plan.

a.  Amendment and Termination.  The Board may at any time amend, alter, 
suspend or terminate the Plan.  

b.  Shareholder Approval.  The Company shall obtain shareholder approval of 
any Plan amendment to the extent necessary and desirable to comply with 
Applicable Laws. 

c.  Effect of Amendment or Termination.  No amendment, alteration, suspension 
or termination of the Plan shall impair the rights of any Optionee, unless 
mutually agreed otherwise between the Optionee and the Administrator, which 
agreement must be in writing and signed by the Optionee and the Company.  
Termination of the Plan shall not affect the Administrator's ability to 
exercise the powers granted to it hereunder with respect to options granted 
under the Plan prior to the date of such termination.

16.  Conditions Upon Issuance of Shares.  

a.  Legal Compliance.  Shares shall not be issued pursuant to the exercise of 
an Option or Stock Purchase Right unless the exercise of such Option or Stock 
Purchase Right and the issuance and delivery of such Shares shall comply with 
Applicable Laws and shall be further subject to the approval of counsel for 
the Company with respect to such compliance.

b.  Investment Representations.  As a condition to the exercise of an Option 
or Stock Purchase Right, the Company may require the person exercising such 
Option or Stock Purchase Right 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 a representation is required.

17.  Inability to Obtain Authority.  The inability of the Company to obtain 
authority from any regulatory body having jurisdiction, which authority is 
deemed by the Company's counsel to be necessary to the lawful issuance and 
sale of any Shares hereunder, shall relieve the Company of any liability in 
respect of the failure to issue or sell such Shares as to which such requisite 
authority shall not have been obtained.

18.  Reservation of Shares.  The Company, during the term of this Plan, will 
at all times reserve and keep available such number of Shares as shall be 
sufficient to satisfy the requirements of the Plan.

19.  Shareholder Approval.  The Plan shall be subject to approval by the 
shareholders of the Company within twelve (12) months after the date the Plan 
is adopted.  Such shareholder approval shall be obtained in the manner and to 
the degree required under Applicable Laws.

     Term/Expiration Date:           _________________________


Vesting Schedule:

This Option may be exercised, in whole or in part, in accordance with the 
following schedule:

25% of the Shares subject to the Option shall vest twelve months after the 
Vesting Commencement Date, and 1/48 of the Shares subject to the Option shall 
vest each month thereafter, subject to the Optionee continuing to be a Service

Termination Period:

This Option may be exercised for 30 days after Optionee ceases to be a Service 
Provider.  Upon the death or Disability of the Optionee, this Option may be

above.

II.  AGREEMENT

1.  Grant of Option.  The Plan Administrator of the Company hereby grants to 
the Optionee named in the Notice of Grant attached as Part I of this Agreement 
(the "Optionee") an option (the "Option") to purchase the number of Shares, as 
set forth in the Notice of Grant, at the exercise price per share set forth in 
the Notice of Grant (the "Exercise Price"), subject to the terms and 
conditions of the Plan, which is incorporated herein by reference.  Subject to 
Section 15(c) of the Plan, in the event of a conflict between the terms and 
conditions of the Plan and the terms and conditions of this Option Agreement, 
the terms and conditions of the Plan shall prevail.

If designated in the Notice of Grant as an Incentive Stock Option ("ISO"), 
this Option is intended to qualify as an Incentive Stock Option under 
Section 422 of the Code.  However, if this Option is intended to be an 
Incentive Stock Option, to the extent that it exceeds the $100,000 rule of 
Code Section 422(d) it shall be treated as a Nonstatutory Stock Option 
("NSO").

2.  Exercise of Option.

a.  Right to Exercise.  This Option is exercisable during its term in 
accordance with the Vesting Schedule set out in the Notice of Grant and the 
applicable provisions of the Plan and this Option Agreement.

b.  Method of Exercise.  This Option is exercisable by delivery of an exercise 
notice, in the form attached as Exhibit A (the "Exercise Notice"), which shall 
state the election to exercise the Option, the number of Shares in respect of 
which the Option is being exercised (the "Exercised Shares"), and such other 
representations and agreements as may be required by the Company pursuant to 
the provisions of the Plan.  The Exercise Notice shall be completed by the 
Optionee and delivered to the Company.  The Exercise Notice shall be 
accompanied by payment of the aggregate Exercise Price as to all Exercised 
Shares.  This Option shall be deemed to be exercised upon receipt by the 
Company of such fully executed Exercise Notice accompanied by such aggregate 
Exercise Price.

No Shares shall be issued pursuant to the exercise of this Option unless such 
issuance and exercise complies with Applicable Laws.  Assuming such 
compliance, for income tax purposes the Exercised Shares shall be considered 
transferred to the Optionee on the date the Option is exercised with respect 
to such Exercised Shares.

3.  Method of Payment.  Payment of the aggregate Exercise Price shall be by 
any of the following, or a combination thereof, at the election of the 
Optionee:

a.  cash; 

b.  check; 

c.  consideration received by the Company under a cashless exercise program 
implemented by the Company in connection with the Plan;  

d.  surrender of other Shares which (i) in the case of Shares acquired upon 
exercise of an option, have been owned by the Optionee for more than six (6) 
months on the date of surrender, and (ii) have a Fair Market Value on the date 
of surrender equal to the aggregate Exercise Price of the Exercised Shares; or

e.  with the Administrator's consent, delivery of Optionee's promissory note 
(the "Note") in the form attached hereto as Exhibit C, in the amount of the 
aggregate Exercise Price of the Exercised Shares together with the execution 
and delivery by the Optionee of the Security Agreement attached hereto as 
Exhibit B.  The Note shall bear interest at the "applicable federal rate" 
prescribed under the Code and its regulations at time of purchase, and shall 
be secured by a pledge of the Shares purchased by the Note pursuant to the 
Security Agreement.

4.  Non-Transferability of Option.  This Option may not be transferred in any 
manner otherwise than by will or by the laws of descent or distribution and 
may be exercised during the lifetime of Optionee only by the Optionee.  The 
terms of the Plan and this Option Agreement shall be binding upon the 
executors, administrators, heirs, successors and assigns of the Optionee.

5.  Term of Option.  This Option may be exercised only within the term set out 
in the Notice of Grant, and may be exercised during such term only in 
accordance with the Plan and the terms of this Option Agreement.

6.  Tax Consequences.  Some of the federal tax consequences relating to this 
Option, as of the date of this Option, are set forth below.  THIS SUMMARY IS 
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO 
CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS 
OPTION OR DISPOSING OF THE SHARES.

a.  Exercising the Option.

i.  Nonstatutory Stock Option.  The Optionee may incur regular federal income 
tax liability upon exercise of a NSO.  The Optionee will be treated as having 
received compensation income (taxable at ordinary income tax rates) equal to 
the excess, if any, of the Fair Market Value of the Exercised Shares on the 
date of exercise over their aggregate Exercise Price.  If the Optionee is an 
Employee or a former Employee, the Company will be required to withhold from 
his or her compensation or collect from Optionee and pay to the applicable 
taxing authorities an amount in cash equal to a percentage of this 
compensation income at the time of exercise, and may refuse to honor the 
exercise and refuse to deliver Shares if such withholding amounts are not 
delivered at the time of exercise.

ii.  Incentive Stock Option.  If this Option qualifies as an ISO, the Optionee 
will have no regular federal income tax liability upon its exercise, although 
the excess, if any, of the Fair Market Value of the Exercised Shares on the 
date of exercise over their aggregate Exercise Price will be treated as an 
adjustment to alternative minimum taxable income for federal tax purposes and 
may subject the Optionee to alternative minimum tax in the year of exercise.  
In the event that the Optionee ceases to be an Employee but remains a Service 
Provider, any Incentive Stock Option of the Optionee that remains unexercised 
shall cease to qualify as an Incentive Stock Option and will be treated for 
tax purposes as a Nonstatutory Stock Option on the date three (3) months and 
one (1) day following such change of status.

b.  Disposition of Shares.  

i.  NSO.  If the Optionee holds NSO Shares for at least one year, any gain 
realized on disposition of the Shares will be treated as long-term capital 
gain for federal income tax purposes.

ii.  ISO.  If the Optionee holds ISO Shares for at least one year after 
exercise and two years after the grant date, any gain realized on disposition 
of the Shares will be treated as long-term capital gain for federal income tax 
purposes.  If the Optionee disposes of ISO Shares within one year after 
exercise or two years after the grant date, any gain realized on such 
disposition will be treated as compensation income (taxable at ordinary income 
rates) to the extent of the excess, if any, of the lesser of (A) the 
difference between the Fair Market Value of the Shares acquired on the date of 
exercise and the aggregate Exercise Price, or (B) the difference between the 
sale price of such Shares and the aggregate Exercise Price.  Any additional 
gain will be taxed as capital gain, short-term or long-term depending on the 
period that the ISO Shares were held.

c.  Notice of Disqualifying Disposition of ISO Shares.  If the Optionee sells 
or otherwise disposes of any of the Shares acquired pursuant to an ISO on or 
before the later of (i) two years after the grant date, or (ii) one year after 
the exercise date, the Optionee shall immediately notify the Company in 
writing of such disposition.  The Optionee agrees that he or she may be 
subject to income tax withholding by the Company on the compensation income 
recognized from such early disposition of ISO Shares by payment in cash or out 
of the current earnings paid to the Optionee.

7.  Entire Agreement; Governing Law.  The Plan is incorporated herein by 
reference.  The Plan and this Option Agreement constitute the entire agreement 
of the parties with respect to the subject matter hereof and supersede in 
their entirety all prior undertakings and agreements of the Company and 
Optionee with respect to the subject matter hereof, and may not be modified 
adversely to the Optionee's interest except by means of a writing signed by 
the Company and Optionee.  This agreement is governed by the internal 
substantive laws, but not the choice of law rules, of Arizona.

8.  NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND AGREES THAT 
THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY 
BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT 
THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES 
HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE 
TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN 
DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A 
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL 
NOT INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE 
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT 
CAUSE.

By your signature and the signature of the Company's representative below, you 
and the Company agree that this Option is granted under and governed by the 
terms and conditions of the Plan and this Option Agreement.  Optionee has 
reviewed the Plan and this Option Agreement in their entirety, has had an 
opportunity to obtain the advice of counsel prior to executing this Option 
Agreement and fully understands all provisions of the Plan and Option 
Agreement.  Optionee hereby agrees to accept as binding, conclusive and final 
all decisions or interpretations of the Administrator upon any questions 
relating to the Plan and Option Agreement.  Optionee further agrees to notify 
the Company upon any change in the residence address indicated below.

                              CONSENT OF SPOUSE

The undersigned spouse of Optionee has read and hereby approves the terms and 
conditions of the Plan and this Option Agreement.  In consideration of the 
Company's granting his or her spouse the right to purchase Shares as set forth

This Security Agreement is made as of __________, 19___ between CompuRAD, 
Inc., a Delaware corporation ("Pledgee"), and _________________________ 
("Pledgor").


Recitals

Pursuant to Pledgor's election to purchase Shares under the Option Agreement 
dated ________ (the "Option"), between Pledgor and Pledgee under Pledgee's 
1996 Stock Plan, and Pledgor's election under the terms of the Option to pay 
for such shares with his promissory note (the "Note"), Pledgor has purchased 
_________ shares of Pledgee's Common Stock (the "Shares") at a price of 
$________ per share, for a total purchase price of $__________.  The Note and 
the obligations thereunder are as set forth in Exhibit C to the Option.

NOW, THEREFORE, it is agreed as follows:

1.  Creation and Description of Security Interest.  In consideration of the 
transfer of the Shares to Pledgor under the Option Agreement, Pledgor, 
pursuant to the Arizona Commercial Code, hereby pledges all of such Shares 
(herein sometimes referred to as the "Collateral") represented by certificate 
number ______, duly endorsed in blank or with executed stock powers, and 
herewith delivers said certificate to the Secretary of Pledgee 
("Pledgeholder"), who shall hold said certificate subject to the terms and 
conditions of this Security Agreement.

The pledged stock (together with an executed blank stock assignment for use in 
transferring all or a portion of the Shares to Pledgee if, as and when 
required pursuant to this Security Agreement) shall be held by the 
Pledgeholder as security for the repayment of the Note, and any extensions or 
renewals thereof, to be executed by Pledgor pursuant to the terms of the 
Option, and the Pledgeholder shall not encumber or dispose of such Shares 
except in accordance with the provisions of this Security Agreement.

2.  Pledgor's Representations and Covenants.  To induce Pledgee to enter into 
this Security Agreement, Pledgor represents and covenants to Pledgee, its 
successors and assigns, as follows:

a.  Payment of Indebtedness.  Pledgor will pay the principal sum of the Note 
secured hereby, together with interest thereon, at the time and in the manner 
provided in the Note.

b.  Encumbrances.  The Shares are free of all other encumbrances, defenses and 
liens, and Pledgor will not further encumber the Shares without the prior 
written consent of Pledgee.

c.  Margin Regulations.  In the event that Pledgee's Common Stock is now or 
later becomes margin-listed by the Federal Reserve Board and Pledgee is 
classified as a "lender" within the meaning of the regulations under Part 207 
of Title 12 of the Code of Federal Regulations ("Regulation G"), Pledgor 
agrees to cooperate with Pledgee in making any amendments to the Note or 
providing any additional collateral as may be necessary to comply with such 
regulations.

3.  Voting Rights.  During the term of this pledge and so long as all payments 
of principal and interest are made as they become due under the terms of the 
Note, Pledgor shall have the right to vote all of the Shares pledged 
hereunder.

4.  Stock Adjustments.  In the event that during the term of the pledge any 
stock dividend, reclassification, readjustment or other changes are declared 
or made in the capital structure of Pledgee, all new, substituted and 
additional shares or other securities issued by reason of any such change 
shall be delivered to and held by the Pledgee under the terms of this Security 
Agreement in the same manner as the Shares originally pledged hereunder.  In 
the event of substitution of such securities, Pledgor, Pledgee and 
Pledgeholder shall cooperate and execute such documents as are reasonable so 
as to provide for the substitution of such Collateral and, upon such sub-
stitution, references to "Shares" in this Security Agreement shall include the 
substituted shares of capital stock of Pledgor as a result thereof.

5.  Options and Rights.  In the event that, during the term of this pledge, 
subscription Options or other rights or options shall be issued in connection 
with the pledged Shares, such rights, Options and options shall be the 
property of Pledgor and, if exercised by Pledgor, all new stock or other 
securities so acquired by Pledgor as it relates to the pledged Shares then 
held by Pledgeholder shall be immediately delivered to Pledgeholder, to be 
held under the terms of this Security Agreement in the same manner as the 
Shares pledged.

6.  Default.  Pledgor shall be deemed to be in default of the Note and of this 
Security Agreement in the event:

a.  Payment of principal or interest on the Note shall be delinquent for a 
period of 10 days or more; or

b.  Pledgor fails to perform any of the covenants set forth in the Option or 
contained in this Security Agreement for a period of 10 days after written 
notice thereof from Pledgee.

In the case of an event of Default, as set forth above, Pledgee shall have the 
right to accelerate payment of the Note upon notice to Pledgor, and Pledgee 
shall thereafter be entitled to pursue its remedies under the Arizona 
Commercial Code.

7.  Release of Collateral.  Subject to any applicable contrary rules under 
Regulation G, there shall be released from this pledge a portion of the 
pledged Shares held by Pledgeholder hereunder upon payments of the principal 
of the Note.  The number of the pledged Shares which shall be released shall 
be that number of full Shares which bears the same proportion to the initial 
number of Shares pledged hereunder as the payment of principal bears to the 
initial full principal amount of the Note.

8.  Withdrawal or Substitution of Collateral.  Pledgor shall not sell, 
withdraw, pledge, substitute or otherwise dispose of all or any part of the 
Collateral without the prior written consent of Pledgee.

9.  Term.  The within pledge of Shares shall continue until the payment of all 
indebtedness secured hereby, at which time the remaining pledged stock shall 
be promptly delivered to Pledgor, subject to the provisions for prior release 
of a portion of the Collateral as provided in paragraph 7 above.

10.  Insolvency.  Pledgor agrees that if a bankruptcy or insolvency proceeding 
is instituted by or against it, or if a receiver is appointed for the property 
of Pledgor, or if Pledgor makes an assignment for the benefit of creditors, 
the entire amount unpaid on the Note shall become immediately due and payable, 
and Pledgee may proceed as provided in the case of default.

11.  Pledgeholder Liability.  In the absence of willful or gross negligence, 
Pledgeholder shall not be liable to any party for any of his acts, or 
omissions to act, as Pledgeholder.

12.  Invalidity of Particular Provisions.  Pledgor and Pledgee agree that the 
enforceability or invalidity of any provision or provisions of this Security 
Agreement shall not render any other provision or provisions herein contained 
unenforceable or invalid.

13.  Successors or Assigns.  Pledgor and Pledgee agree that all of the terms 
of this Security Agreement shall be binding on their respective successors and 
assigns, and that the term "Pledgor" and the term "Pledgee" as used herein 
shall be deemed to include, for all purposes, the respective designees, 
successors, assigns, heirs, executors and administrators.

14.  Governing Law.  This Security Agreement shall be interpreted and governed 
under the internal substantive laws, but not the choice of law rules, of 
Arizona.


IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the 
day and year first above written.

                               1996 STOCK PLAN

                      RESTRICTED STOCK PURCHASE AGREEMENT

Unless otherwise defined herein, the terms defined in the Plan shall have the 
same defined meanings in this Restricted Stock Purchase Agreement.

WHEREAS the Purchaser named in the Notice of Grant, (the "Purchaser") is an  
Service Provider, and the Purchaser's continued participation is considered by 
the Company to be important for the Company's continued growth; and

WHEREAS in order to give the Purchaser an opportunity to acquire an equity 
interest in the Company as an incentive for the Purchaser to participate in 
the affairs of the Company, the Administrator has granted to the Purchaser a 
Stock Purchase Right subject to the terms and conditions of the Plan and the 
Notice of Grant, which are incorporated herein by reference, and pursuant to 
this Restricted Stock Purchase Agreement (the "Agreement").

NOW THEREFORE, the parties agree as follows:

1.  Sale of Stock.  The Company hereby agrees to sell to the Purchaser and the 
Purchaser hereby agrees to purchase shares of the Company's Common Stock (the 
"Shares"), at the per Share purchase price and as otherwise described in the 
Notice of Grant.

2.  Payment of Purchase Price.  The purchase price for the Shares may be paid 
by delivery to the Company at the time of execution of this Agreement of cash, 
a check, or some combination thereof.

3.  Repurchase Option.

a.  In the event the Purchaser ceases to be a Service Provider for any or no 
reason (including death or disability) before all of the Shares are released 
from the Company's Repurchase Option (see Section 4), the Company shall, upon 
the date of such termination (as reasonably fixed and determined by the 
Company) have an irrevocable, exclusive option (the "Repurchase Option") for a 
period of sixty (60) days from such date to repurchase up to that number of 
shares which constitute the Unreleased Shares (as defined in Section 4) at the 
original purchase price per share (the "Repurchase Price").  The Repurchase 
Option shall be exercised by the Company by delivering written notice to the 
Purchaser or the Purchaser's executor (with a copy to the Escrow Holder) AND, 
at the Company's option, (i) by delivering to the Purchaser or the Purchaser's 
executor a check in the amount of the aggregate Repurchase Price, or (ii) by 
cancelling an amount of the Purchaser's indebtedness to the Company equal to 
the aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so 
that the combined payment and cancellation of indebtedness equals the 
aggregate Repurchase Price.  Upon delivery of such notice and the payment of 
the aggregate Repurchase Price, the Company shall become the legal and 
beneficial owner of the Shares being repurchased and all rights and interests 
therein or relating thereto, and the Company shall have the right to retain 
and transfer to its own name the number of Shares being repurchased by the 
Company.

b.  Whenever the Company shall have the right to repurchase Shares hereunder, 
the Company may designate and assign one or more employees, officers, 
directors or shareholders of the Company or other persons or organizations to 
exercise all or a part of the Company's purchase rights under this Agreement 
and purchase all or a part of such Shares.  If the Fair Market Value of the 
Shares to be repurchased on the date of such designation or assignment (the 
"Repurchase FMV") exceeds the aggregate Repurchase Price of such Shares, then 
each such designee or assignee shall pay the Company cash equal to the 
difference between the Repurchase FMV and the aggregate Repurchase Price of 
such Shares.

4.  Release of Shares From Repurchase Option.

a.  _______________________  percent (______%) of the Shares shall be released 
from the Company's Repurchase Option one year after the Date of Grant and 
__________________ percent (______%) of the Shares [at the end of each month 
thereafter], provided that the Purchaser does not cease to be a Service 
Provider prior to the date of any such release.

b.  Any of the Shares that have not yet been released from the Repurchase 
Option are referred to herein as "Unreleased Shares."

c.  The Shares that have been released from the Repurchase Option shall be 
delivered to the Purchaser at the Purchaser's request (see Section 6).

5.  Restriction on Transfer.  Except for the escrow described in Section 6 or 
the transfer of the Shares to the Company or its assignees contemplated by 
this Agreement, none of the Shares or any beneficial interest therein shall be 
transferred, encumbered or otherwise disposed of in any way until such Shares 
are released from the Company's Repurchase Option in accordance with the 
provisions of this Agreement, other than by will or the laws of descent and 
distribution.

6.  Escrow of Shares.

a.  To ensure the availability for delivery of the Purchaser's Unreleased 
Shares upon repurchase by the Company pursuant to the Repurchase Option, the 
Purchaser shall, upon execution of this Agreement, deliver and deposit with an 
escrow holder designated by the Company (the "Escrow Holder") the share 
certificates representing the Unreleased Shares, together with the stock 
assignment duly endorsed in blank, attached hereto as Exhibit A-2.  The 
Unreleased Shares and stock assignment shall be held by the Escrow Holder, 
pursuant to the Joint Escrow Instructions of the Company and Purchaser 
attached hereto as Exhibit A-3, until such time as the Company's Repurchase 
Option expires.  As a further condition to the Company's obligations under 
this Agreement, the Company may require the spouse of Purchaser, if any, to 
execute and deliver to the Company the Consent of Spouse attached hereto as 
Exhibit A-4.

b.  The Escrow Holder shall not be liable for any act it may do or omit to do 
with respect to holding the Unreleased Shares in escrow while acting in good 
faith and in the exercise of its judgment.

c.  If the Company or any assignee exercises the Repurchase Option hereunder, 
the Escrow Holder, upon receipt of written notice of such exercise from the 
proposed transferee, shall take all steps necessary to accomplish such 
transfer.

d.  When the Repurchase Option has been exercised or expires unexercised or a 
portion of the Shares has been released from the Repurchase Option, upon 
request the Escrow Holder shall promptly cause a new certificate to be issued 
for the released Shares and shall deliver the certificate to the Company or 
the Purchaser, as the case may be.

e.  Subject to the terms hereof, the Purchaser shall have all the rights of a 
shareholder with respect to the Shares while they are held in escrow, 
including without limitation, the right to vote the Shares and to receive any 
cash dividends declared thereon.  If, from time to time during the term of the 
Repurchase Option, there is (i) any stock dividend, stock split or other 
change in the Shares, or (ii) any merger or sale of all or substantially all 
of the assets or other acquisition of the Company, any and all new, 
substituted or additional securities to which the Purchaser is entitled by 
reason of the Purchaser's ownership of the Shares shall be immediately subject 
to this escrow, deposited with the Escrow Holder and included thereafter as 
"Shares" for purposes of this Agreement and the Repurchase Option.

7.  Legends.  The share certificate evidencing the Shares, if any,  issued 
hereunder shall be endorsed with the following legend (in addition to any 
legend required under applicable state securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS 
UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN 
THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY 
OF THE COMPANY.

8.  Adjustment for Stock Split.  All references to the number of Shares and 
the purchase price of the Shares in this Agreement shall be appropriately 
adjusted to reflect any stock split, stock dividend or other change in the 
Shares which may be made by the Company after the date of this Agreement.

9.  Tax Consequences.  The Purchaser has reviewed with the Purchaser's own tax 
advisors the federal, state, local and foreign tax consequences of this 
investment and the transactions contemplated by this Agreement.  The Purchaser 
is relying solely on such advisors and not on any statements or 
representations of the Company or any of its agents.  The Purchaser 
understands that the Purchaser (and not the Company) shall be responsible for 
the Purchaser's own tax liability that may arise as a result of the 
transactions contemplated by this Agreement.  The Purchaser understands that 
Section 83 of the Internal Revenue Code of 1986, as amended (the "Code"), 
taxes as ordinary income the difference between the purchase price for the 
Shares and the Fair Market Value of the Shares as of the date any restrictions 
on the Shares lapse.  In this context, "restriction" includes the right of the 
Company to buy back the Shares pursuant to the Repurchase Option.  The 
Purchaser understands that the Purchaser may elect to be taxed at the time the 
Shares are purchased rather than when and as the Repurchase Option expires by 
filing an election under Section 83(b) of the Code with the IRS within 30 days 
from the date of purchase.  The form for making this election is attached as 
Exhibit A-5 hereto.

THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE RESPONSIBILITY AND 
NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF THE 
PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON 
THE PURCHASER'S BEHALF.

10.  General Provisions.

a.  This Agreement shall be governed by the internal substantive laws, but not 
the choice of law rules of Arizona.  This Agreement, subject to the terms and 
conditions of the Plan and the Notice of Grant, represents the entire agree-
ment between the parties with respect to the purchase of the Shares by the 
Purchaser.  Subject to Section 15(c) of the Plan, in the event of a conflict 
between the terms and conditions of the Plan and the terms and conditions of 
this Agreement, the terms and conditions of the Plan shall prevail.  Unless 
otherwise defined herein, the terms defined in the Plan shall have the same 
defined meanings in this Agreement.

b.  Any notice, demand or request required or permitted to be given by either 
the Company or the Purchaser pursuant to the terms of this Agreement shall be 
in writing and shall be deemed given when delivered personally or deposited in 
the U.S. mail, First Class with postage prepaid, and addressed to the parties

Dear ___________________:

"Purchaser"), you are hereby authorized and directed to hold the documents 
delivered to you pursuant to the terms of that certain Restricted Stock 
Purchase Agreement ("Agreement") between the Company and the undersigned, in 
accordance with the following instructions:

1.  In the event the Company and/or any assignee of the Company (referred to 
collectively as the "Company") exercises the Company's Repurchase Option set 
forth in the Agreement, the Company shall give to Purchaser and you a written 
notice specifying the number of shares of stock to be purchased, the purchase 
price, and the time for a closing hereunder at the principal office of the 
Company.  Purchaser and the Company hereby irrevocably authorize and direct 
you to close the transaction contemplated by such notice in accordance with 
the terms of said notice.

2.  At the closing, you are directed (a) to date the stock assignments 
necessary for the transfer in question, (b) to fill in the number of shares 
being transferred, and (c) to deliver same, together with the certificate 
evidencing the shares of stock to be transferred, to the Company or its 
assignee, against the simultaneous delivery to you of the purchase price (by 
cash, a check, or some combination thereof) for the number of shares of stock 
being purchased pursuant to the exercise of the Company's Repurchase Option.

3.  Purchaser irrevocably authorizes the Company to deposit with you any 
certificates evidencing shares of stock to be held by you hereunder and any 
additions and substitutions to said shares as defined in the Agreement.  
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's 
attorney-in-fact and agent for the term of this escrow to execute with respect 
to such securities all documents necessary or appropriate to make such

4.  Upon written request of the Purchaser, but no more than once per calendar 
year, unless the Company's Repurchase Option has been exercised, you shall

Purchaser a certificate or certificates representing the aggregate number of 
shares held or issued pursuant to the Agreement and not purchased by the 
Company or its assignees pursuant to exercise of the Company's Repurchase 
Option.

5.  If at the time of termination of this escrow you should have in your 
possession any documents, securities, or other property belonging to 
Purchaser, you shall deliver all of the same to Purchaser and shall be 
discharged of all further obligations hereunder.

6.  Your duties hereunder may be altered, amended, modified or revoked only by 
a writing signed by all of the parties hereto.

7.  You shall be obligated only for the performance of such duties as are 
specifically set forth herein and may rely and shall be protected in relying

You shall not be personally liable for any act you may do or omit to do 
hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in 
good faith, and any act done or omitted by you pursuant to the advice of your 
own attorneys shall be conclusive evidence of such good faith.

8.  You are hereby expressly authorized to disregard any and all warnings 
given by any of the parties hereto or by any other person or corporation, 
excepting only orders or process of courts of law, and are hereby expressly 
authorized to comply with and obey orders, judgments or decrees of any court. 
 In case you obey or comply with any such order, judgment or decree, you shall 
not be liable to any of the parties hereto or to any other person, firm or 
corporation by reason of such compliance, notwithstanding any such order, 
judgment or decree being subsequently reversed, modified, annulled, set aside, 
vacated or found to have been entered without jurisdiction.

9.  You shall not be liable in any respect on account of the identity, 
authorities or rights of the parties executing or delivering or purporting to 
execute or deliver the Agreement or any documents or papers deposited or 
called for hereunder.

10.  You shall not be liable for the outlawing of any rights under the statute

you may deem necessary properly to advise you in connection with your 
obligations hereunder, may rely upon the advice of such counsel, and may pay 
such counsel reasonable compensation therefor.

shall cease to be an officer or agent of the Company or if you shall resign by 
written notice to each party.  In the event of any such termination, the 
Company shall appoint a successor Escrow Agent.

13.  If you reasonably require other or further instruments in connection with 
these Joint Escrow Instructions or obligations in respect hereto, the 
necessary parties hereto shall join in furnishing such instruments.

14.  It is understood and agreed that should any dispute arise with respect to 
the delivery and/or ownership or right of possession of the securities held by 
you hereunder, you are authorized and directed to retain in your possession 
without liability to anyone all or any part of said securities until such 
disputes shall have been settled either by mutual written agreement of the 
parties concerned or by a final order, decree or judgment of a court of 
competent jurisdiction after the time for appeal has expired and no appeal has 
been perfected, but you shall be under no duty whatsoever to institute or 
defend any such proceedings.

15.  Any notice required or permitted hereunder shall be given in writing and 
shall be deemed effectively given upon personal delivery or upon deposit in 
the United States Post Office, by registered or certified mail with postage

                               STOCK OPTION PLAN, 
                      FORM OF NOTICE OF STOCK OPTION GRANT


                                 COMPUMED, INC. 

                               STOCK OPTION PLAN


COMPUMED, INC., an Arizona corporation (the "Company") for the benefit of 
certain of its key employees, and as an additional incentive to further the 
goals and objectives of the Company hereby established the CompuMed, Inc. 
Stock Option Plan, a nonstatutory stock option plan, under the following terms 
and conditions:

1.  Effective Date.

The effective date of the CompuMed, Inc. Stock Option Plan (the "Plan") is 
October __, 1994.

2.  Purpose.

The purpose of this Plan is to promote the interests of the Company by 
affording an incentive to certain officers and key employees to remain in the 
Company's employ and to use their best efforts on its behalf; and to further 
assist the Company in attracting, maintaining and developing capable personnel 
in order to insure the Company's continued profitability, by means of 
providing such officers and key employees an opportunity to acquire a 
proprietary interest in the Company through stock options granted pursuant to 
the terms of this Plan.

3.  Eligible Employees.

Stock options may be granted under this Plan from time to time to the 
Company's officers, key employees or other persons affiliated with the 
Company, in connection with services rendered by such persons to the Company, 
as determined by the Board of Directors.  An officer, key employee or other 
individual who is granted an option under this Plan is not precluded from 
later being granted additional options hereunder if the Board of Directors 
shall so determine.  Notwithstanding the foregoing, unless amended by the 
Board of Directors, grants of options hereunder which occur after October 31, 
1994 shall be subject to the following general allocation provisions.

a.  Management Department.

One third (1/3) of all options granted hereunder shall be granted to 
individuals within the Management Department.

b.  Sales Department.

One third (1/3) of all options granted hereunder shall be granted to 
individuals within the Sales Department.

c.  Engineering Department.

One third (1/3) of all options granted hereunder shall be granted to 
individuals within the Engineering Department.

The foregoing shall not be deemed to impose restrictions upon the allocation 
of options granted hereunder within the above described departments, which 
shall be established in accordance with resolutions adopted by the Board of 
Directors, and set forth in the applicable Stock Option Agreements.

4.  Administration.

The Plan shall be administered by the Board of Directors of the Company.  The 
Board of Directors may grant options only with the consent of a majority Of 
its members.  The Board of Directors shall have full and final authority in 
exercising its discretion, subject to the applicable provisions of the Plan, 
to determine the individuals to whom, and the time or times at which the 
options shall be granted.  The Board of Directors shall also determine the 
number of shares and the purchase price for shares covered by each option.  
The Board of Directors is further empowered to construe and interpret the 
Plan, to determine the terms and provisions Of the option agreements (which 
agreements may vary in their terms), including, without limitation, terms 
covering the payment of the option price.  The Board of Directors is further 
authorized to make all other determinations and to take all other actions that 
it deems necessary, advisable, or proper for the administration of the Plan.  
All such determinations and actions taken by the Board of Directors shall be 
conclusively binding for all purposes of the Plan.

5.  Indemnification.

The Company shall indemnify and hold harmless each person who is or has been a 
member of the Board of Directors, against and from any and all loss, expense, 
liability, or costs (including reasonable attorney's fees) that may be imposed 
upon or reasonably incurred by him in connect/on with or resulting from any 
claim, action, suit, or proceeding to which he may be a party or in which he 
may be involved by reason of any action taken or failure to act under the 
Plan; and against and from any and all amounts paid by him in settlement 
thereof with the Company's approval, or paid by him in satisfaction of a final 
judgment against him in any such action, suit, or proceeding, provided he 
shall give the Company an opportunity, at its own expense, to handle and 
defend the same before he undertakes to handle and defend it on his own 
behalf.  The right of indemnification herein set forth shall not be exclusive 
of any other rights of indemnification to which such person may be entitled 
under the Company's articles of incorporation or code of regulations, as a 
matter of law, or otherwise, or any power that the Company may have to 
indemnify him or hold him harmless.  It is the Company's intention that all 
expenses incurred in connection with the administration of the Plan shall be 
born by the Company rather than by the Board of Directors.

6.  Stock Subject to Options.

The Board of Directors shall reserve for the purposes of the Plan a total of 
Five Hundred Thousand (500,000) shares of no par value common stock of the 
Company(the "Common Stock").  Such shares of Common Stock may be derived in 
whole or in part, as the Board of Directors may determine, from authorized and 
unissued shares or previously issued shares of Common Stock which the Company 
may have reacquired.  If any option granted hereunder shall expire or 
terminate for any reason without having been exercised in full, the 
unpurchased shares subject hereto shall again be available for the purposes of 
this Plan.  The number of shares of Common Stock reserved for the Plan may be 
adjusted in accordance with the provisions of Section 8 below.

7.  Option Terms.

All options granted hereunder shall be evidenced by a Stock Option Agreement 
entered into by the recipient of the stock option and a duly authorized 
officer of the Company designated by the Board of Directors.  The Stock Option 
Agreement shall contain such terms and be in such form as the Board of 
Directors may determine from time to time, subject to the following 
limitations and conditions:

a.  Option Price.

The option price per share with respect to each option granted hereunder shall 
be the net book value of a share of the Company's Common Stock on the date the 
option is granted.  Such net book value shall be the net book value thereof as 
of the last day of the month prior to the date of grant as determined in 
accordance with generally accepted accounting principles consistently applied; 
provided that deferred compensation shall not be considered as a corporate 
liability when calculating net book value for purposes of this Section 7.1.

b.  Time of Exercise.

Each option granted hereunder shall be exercisable from time to time over a 
period commencing upon the date on which the option is granted and ending on 
the expiration or termination of the option period as such terms are set forth 
in the Stock Option Agreement which, in any event, shall not extend beyond 
fifteen (15) years following the date of grant.  The Board of Directors may, 
by provisions of any Stock Option Agreement, limit the number of shares which 
may be purchased thereunder in any period or periods of time during which the 
option is exercisable, and/or utilize vesting schedules consistent with the 
general provisions hereof.

c.  Manner of Exercise.

Options granted hereunder may be exercised by written notice directed to the 
Board of Directors at the Company's principal place of business, accompanied 
by a check in payment of the option price for the number of shares specified 
in the notice.  The Company shall deliver the certificates representing the 
shares of Common Stock acquired pursuant to the exercise of the option, within 
fifteen (15) business days after its receipt of the aforesaid notice and 
check.  Notwithstanding the foregoing, if any federal or state securities law 
or regulation requires the Company to take any action with respect to the 
shares of Common Stool< specified in such notice before the issuance thereof, 
then the date of delivery of such shares shall be extended for the period 
necessary to take such action.

8.  Antidilution.

In the event that the outstanding shares of Common Stock are subject to a 
stock split or changed into or exchanged for a different number or kind of 
shares or other securities of the Company, or of any other corporation, by 
reason of merger, consolidation, or other reorganization, recapitalization, 
reclassification, combination of shares, stock split, or stock dividend, then 
(i) the total number of shares of Common Stock subject to this Plan shall be 
appropriately adjusted; (ii) the rights of officers and key employees who have 
been granted options hereunder shall be appropriately adjusted as to the 
number of shares of Common Stock subject to the option and/or as to the option 
price; and (iii) if the Company is involved in a dissolution, liquidation, 
merger, or combination in which it is not a surviving corporation, then each 
outstanding option granted hereunder shall terminate thirty (30) days after 
the effective date of such dissolution, liquidation, merger, or combination.  
Within said thirty (30) day period, the optionee may exercise his option in 
whole or in part, to the extent that it shall not have been previously 
exercised.

The Board of Directors shall make the foregoing adjustments in such manner so 
as to preserve the benefits afforded to officers and key employees under this 
Plan.  In making such adjustments, the Board of Directors may provide for the 
elimination of fractional shares of Common Stock.

9.  Nontransferable.

Each option granted hereunder shall, by its terms, be nontransferable by the 
optionee, except pursuant to an optionee's last will or by the laws of 
intestate succession, and except for transfers approved in advance by formal 
resolution of the Board of Directors of the Company.  Each option granted 
hereunder shall be exercisable during the optionee's lifetime only by such 
optionee, his approved assignee or legal representative.

10. No Guarantee of Employment.

Nothing herein or in any option granted pursuant hereto confers or shall 
confer on any individual any right to continue in the employment of the 
Company, nor shall this Plan be deemed to limit or interfere with the 
Company's right to terminate the employment or contractual relationship of any 
person any time.

11.  Miscellaneous.

a.  Governing Law.

This Plan shall be governed by and construed in accordance with the laws of 
the State of Arizona, and any action involving this Plan shall be brought and 
maintained in a court of competent jurisdiction in Pima County, Arizona.

b.  Amendment and Termination.

The Board of Directors may amend, alter, or terminate this Plan, except that 
no amendment or alteration shall be made which would impair the rights of any 
optionee under any option granted pursuant hereto without the consent of such 
optionee.  Notwithstanding the foregoing, the following amendments or

                        PROSPECTUS FOR OPTIONS GRANTED UNDER THE
                            COMPURAD, INC. 1996 STOCK PLAN
                            ASSUMED BY LUMISYS INCORPORATED
                          ________________________________


To Our Optionees:

As a result of the merger on November 25, 1997 of an affiliate of Lumisys 
Incorporated ("Lumisys") with and into CompuRAD, Inc. ("CompuRAD"), CompuRAD 
became a wholly owned subsidiary of Lumisys (the "Merger").  As part of the 
Merger, options originally granted to you by CompuRAD under the 1996 Stock 
Plan (the "Plan") have been assumed by Lumisys.  We are pleased with this 
opportunity to provide you with information regarding the option granted to 
you by CompuRAD (the "CompuRAD Options") under the Plan.  We believe that your 
CompuRAD Option is an important part of the benefits provided to you and hope 
you will take the time to review this information carefully.

Each CompuRAD Option assumed by Lumisys has been converted into an option to 
purchase that number of shares of Lumisys common stock determined by 
multiplying the number of shares of CompuRAD common stock for which you hold 
CompuRAD Options by 0.928 and rounding down to the nearest whole number (with 
cash, less the applicable exercise price, being payable for any fraction of a 
share).  The exercise price per share will be equal to the exercise price of 
the CompuRAD Options divided by 0.928 rounded up to the nearest cent.  The 
other terms of each CompuRAD Option, including tax status and vesting, will 
remain unchanged. 

We have divided our discussion of the Plan into three parts.  The first part 
of this document describes the terms of the Plan, which provides for the grant 
of incentive stock options (tax advantaged options) and nonstatutory stock 
options (options which do not have tax advantages).  The second and third 
parts of this document describe the tax consequences relating to your CompuRAD 
Option.

The following information and attached materials may not answer all the 
questions you have about the Plan or about Lumisys' assumption of the CompuRAD 
Options and are not intended to go into every detail.  The Vice President, 
Finance of Lumisys at (408) 733-6565 will be happy to answer further 
questions.  A copy of the Plan and an exercise form are attached at the end of 
this package.  If you wish to exercise your CompuRAD Option, you will need to 
complete the exercise form.  You may always obtain copies of the exercise form 
from Lumisys.

                               INFORMATION ABOUT LUMISYS

An important part of your CompuRAD Option is understanding Lumisys, its 
operations and its financial condition.  You can keep yourself informed about 
Lumisys by reviewing reports and other documents which Lumisys prepares for 
stockholders and the general public and which will be provided to you (as 
discussed below).  If you become a stockholder of Lumisys, you will be 
entitled to attend stockholder meetings and to vote in the election of 
directors and on other matters brought before the stockholders.

If you have not already received a copy of Lumisys's current annual report as 
a stockholder of Lumisys, this information  should be delivered to you with 
these materials.  Whether or not you have already received this information, 
you may always request a copy from Lumisys.

In addition,the United States federal securities laws require Lumisys to 
provide information about its business and financial status in annual reports 
commonly known as "10-Ks" and quarterly reports commonly known as "10-Qs." 
These reports are filed with the Securities and Exchange Commission (the 
"Commission").  In addition, if certain important corporate events occur 
during the year, Lumisys may file reports commonly known as "8-Ks."  Lumisys 
also prepares and files with the Commission a proxy statement in connection 
with its annual meeting of stockholders.  The proxy statement provides further 
information about Lumisys and its officers, directors and major stockholders. 
 From time to time Lumisys may also file other documents with the Commission 
as required by Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange 
Act of 1934, as amended (the "Exchange Act").

All of these documents constitute part of the information required by the 
securities laws to be provided or made available to you in connection with 
your CompuRAD Option; that is, these documents are incorporated by reference 
into these materials, which constitute the prospectus for the Plan.  For a 
copy of these documents, all of which are available without charge and upon 
written or oral request, please contact Dean MacIntosh, Vice President, 
Finance, of Lumisys.

1.   WHO DETERMINED WHETHER I RECEIVED AN OPTION AND THE TERMS OF MY OPTION 
AND HOW MANY SHARES OF COMMON STOCK IT COVERED?

The decision to grant an option to any particular individual was made by the 
CompuRAD Board of Directors (the "CompuRAD Board") or by a committee of the 
CompuRAD Board generally after review of input from management.  The Plan 
provided for the grant of options to employees, directors and consultants 
covering an aggregate of 400,000 shares of CompuRAD's common stock.  When the 
CompuRAD Board (or committee) granted your CompuRAD Option, it had the 
discretion to determine the terms of the option, including the number of 
shares the option covered.  However, you could not receive options covering 
more than 200,000 shares in any fiscal year of CompuRAD.  In addition, as 
discussed in Question 2, tax restrictions applied on the number of incentive 
stock options that could be granted to you under certain circumstances.

The Lumisys Board of Directors (the "Lumisys Board") now administers the 
CompuRAD Options and has the power to interpret them.  Information about the 
current members of the Lumisys Board is provided in Lumisys' proxy statement 
for its last annual meeting.  You may obtain additional information about the 
administration of the CompuRAD Options by contacting the Vice President, 
Finance of Lumisys.

When administration of the CompuRAD Options is delegated to a committee, the 
Lumisys Board retains the right to revert authority to construe and interpret 
the options back to itself.  References to the Lumisys Board in this document 
should be construed as references to the committee, as applicable.

2.   WHAT IS THE DIFFERENCE BETWEEN AN INCENTIVE STOCK OPTION AND A 
NONSTATUTORY STOCK OPTION?

If you were not an employee, your CompuRAD Option had to be a nonstatutory 
stock option.  If you were an employee, then at the time the CompuRAD Board 
granted you your option, the CompuRAD Board determined whether the option was 
an incentive stock option or nonstatutory stock option.  This determination 
generally was based on the CompuRAD Board's understanding of the relative tax 
benefits to you and CompuRAD in granting incentive stock options versus 
nonstatutory stock options.  In general, potentially favorable tax treatment 
is provided to the holders of stock options that qualify as incentive stock 
options under the Internal Revenue Code of 1986, as amended (the "Code").  
Upon the exercise of an incentive stock option, an optionee is typically not 
subject to tax except for the possible imposition of alternative minimum tax. 
 (See Question 31.)  Upon the exercise of a nonstatutory stock option, 
however, an optionee generally is taxed based on the difference between the 
exercise price of the option and the fair market value of the stock on the 
date of exercise.  (See Question 21.)  The deferral of the recognition of tax 
until the time of sale of the stock, as well as the possible treatment of the 
"spread" as capital gain, are the principal advantages of incentive stock 
options.  However, incentive stock options have certain limitations on their 
exercise price, terms, transferability and duration.

In addition, the tax laws restricted the CompuRAD Board's ability to grant 
incentive stock options under certain circumstances.  For example, if the 
aggregate value of the shares under all incentive stock options you hold that 
were granted after 1986 and that became exercisable for the first time during 
any calendar year was greater than $100,000, then that number of those shares 
with a value over $100,000 had to be treated as nonstatutory stock options not 
having the tax advantages of incentive stock options.  (However, to avoid this 
result, your incentive stock option may provide that, in the event the 
$100,000 limit would be exceeded, exercisability of the amount over $100,000 
will delayed until the next calendar year.)

The rules governing the tax effects of incentive stock options and 
nonstatutory stock options are complex, and you should carefully read the tax 
information provided in Part II.

3.  HOW WAS THE EXERCISE PRICE OF MY COMPURAD OPTION DETERMINED?

The Code required that the exercise price of an incentive stock option be at 
least 100% of the fair market value of CompuRAD's common stock on the date an 
option was granted (the "grant date").  The Plan provided that the CompuRAD 
Board could set the exercise price for a nonstatutory stock option at any 
price unless the option was intended to qualify as "performance-based 
compensation" within the meaning of Section 162(m) of the Code, in which case 
the exercise price could not less than the fair market value of CompuRAD's 
common stock on the date of grant.  The exercise price for each share of 
Lumisys common stock now covered by your CompuRAD Option, as assumed by 
Lumisys, is the exercise price per share of CompuRAD stock under the option 
immediately before the Merger divided by 0.928, rounded up to the nearest 
cent.  Special rules applied to the exercise price of stock options granted to 
anyone who owned 10% or more of the voting power of CompuRAD or its 
affiliates.  You should speak with the Vice President, Finance of Lumisys if 
you believe these rules might apply to you.

4.  WHEN CAN I EXERCISE MY COMPURAD OPTION?

When the CompuRAD Board granted your CompuRAD Option, it also determined 
certain terms of the option, including the date or dates after which the 
option may be exercised.  You should check your option agreement to determine 
the date(s) on which your shares become exercisable, or "vest."  (However, 
your option may provide that you can exercise your option as to unvested 
shares subject to Lumisys's right to repurchase "unvested" shares.)  CompuRAD 
Options may have a term of 10 years, so you must exercise your option before 
it expires at the end of the 10-year period.  For example, if your option was 
granted on February 1, 1997 and has a full 10-year term, it must be exercised 
before February 1, 2007.  The terms of exercise of options are not required to 
be the same for every optionee.  (For example, each option may have a 
different vesting period or may tie acceleration of vesting to the achievement 
of certain performance goals.)  Please review your option grant carefully to 
be sure that you understand its specific terms and conditions.

5.  HOW DO I EXERCISE MY COMPURAD OPTION?

You exercise your CompuRAD Option by completing an option exercise form and 
delivering the form, together with payment of the exercise price (see 
Question 6 below), to the Vice President, Finance of Lumisys.  You can obtain 
option exercise forms from the Vice President, Finance.

6.  DO I HAVE TO PAY THE EXERCISE PRICE WITH CASH?

You may always pay the exercise price with cash.  However, your CompuRAD 
Option may provide that the exercise price also may be paid with other 
consideration (for example, by delivery to Lumisys of other unencumbered 
common stock of Lumisys you already own with a value equal to the aggregate 
option exercise price or according to a deferred payment or other 
arrangement).  You should review the terms of your option which describes 
specifically the manner in which the exercise price may by paid.  You may be 
able to do a cashless exercise through a broker.  See Question 7.

7.  I HAVE HEARD ABOUT CASHLESS EXERCISE PROGRAMS THROUGH BROKERS.  HOW DO 
THESE WORK?

Cashless exercise programs involve the delivery to a broker of a copy of your 
signed and completed option exercise form and your irrevocable instructions to 
Lumisys to deliver stock to be received upon exercise of the option to the 
broker rather than to you.  Under U.S. Treasury Regulation T, the broker can 
then deliver cash to Lumisys in payment of the exercise price and, in some 
cases, withholding taxes.  Lumisys then delivers the stock certificate to the 
broker.  After the stock is delivered to the broker, the stock can be 
maintained as margin stock in an account designated by you, or it can be sold 
pursuant to your instructions.  However, Lumisys will not participate in any 
Regulation T program which would cause stock certificates to be delivered to 
the broker before Lumisys has received payment for the exercise price or an 
irrevocable guarantee of payment from the sales proceeds.  You should contact 
the Vice President, Finance of Lumisys for information regarding the cashless 
exercise program.  If you are an "insider" when you exercise your CompuRAD 
Option, you should ensure that your cashless exercises are properly structured 
in order to avoid any violation of the prohibition against short sales by 
insiders found in Section 16(c) of the Exchange Act.  In general, "insiders" 
are officers, directors, and 10% stockholders of a publicly-traded company or 
an executive officer of a significant subsidiary of such a company.

8.  WILL I CONTINUE TO RECEIVE OPTIONS UNDER THE PLAN AS LONG AS I CONTINUE 
PROVIDING SERVICES TO LUMISYS?

No, the Lumisys Board cannot grant any additional options under the Plan.  
(Nevertheless, your CompuRAD Option will continue in effect and will be 
governed by the provisions of the Plan and the stock option agreement 
documenting your option.)  However, you may be eligible to receive an option 
under a Lumisys stock option plan.  Whether or not you receive options will 
depend on many factors, such as your performance, Lumisys's overall 
performance, the Lumisys Board's then current policy and the number of shares 
remaining in the Lumisys stock option plan.  You should note that Lumisys' 
assumption of your option does not alter any right to terminate your 
employment at any time and for any reason, with or without cause, or your 
service as a consultant according to the terms of your consultant agreement.

9.  CAN THE TERMS OF MY COMPURAD OPTION BE CHANGED?

The Lumisys Board decides whether to change the terms of the CompuRAD Options 
but your option will not be adversely affected without your consent.  Usually 
options are amended to take into account changes in the tax or securities 
laws.  These changes may be presented to the stockholders of Lumisys for 
approval at Lumisys's annual meeting if tax, securities or other laws require 
approval of the changes.

If certain changes occur to Lumisys's capitalization, e.g., a stock split or 
stock dividend of its common stock, the Lumisys Board will appropriately 
adjust the exercise price and number of shares subject to your option.  If 
Lumisys merges with another company or undergoes certain other types of 
capital reorganizations (a "change in control"), then either the surviving 
corporation will assume your option (or substitute a similar option for your 
option) or the time during which your option may be exercised will be 
accelerated.  However, if exercisability and vesting are accelerated, your 
option will terminate if not exercised prior to such event.

10. WHAT HAPPENS IF I LEAVE LUMISYS?

Whether you leave Lumisys (or an affiliate) voluntarily or your service is 
terminated, your right to exercise any vested portion of your CompuRAD Option 
generally will terminate three months after your last day of service with 
Lumisys.  However, the terms of your option may provide that it will terminate 
sooner than three months after termination of your service or that it may be 
exercised more than three months after such termination.  (If the option is an 
incentive stock option, it generally must be exercised within three months of 
the termination date or it will become a nonstatutory stock option.)  You 
should check your option agreement.  Usually, you will not be able to exercise 
any unvested portion of your option once you have left your employment or 
terminated your engagement as a consultant.

11. WHAT IF I LEAVE LUMISYS BECAUSE OF DISABILITY?

If your service is terminated because of your disability, you should review 
the terms of your CompuRAD Option.  Generally, the option will terminate 12 
months after your last day of service with Lumisys as determined between you 
and Lumisys.  Disability, for these purposes, has a specific meaning found in 
the Code.  You should contact the Vice President, Finance of Lumisys if you 
have any questions regarding what constitutes a disability.

12. WHAT ARE THE RIGHTS OF MY HEIRS UPON MY DEATH?

Your estate or persons having rights to your CompuRAD Option by will or by the 
laws of descent and distribution will have the right to exercise your option 
as to any vested portion of your option if you were still in service at the 
time of death or, if so provided in your option, you died within three months 
after your service was terminated for any reason.  Your option will specify 
the date by which the option must be exercised, which usually will be 12 
months after your death.

13. CAN A RELATIVE OR FRIEND EXERCISE MY COMPURAD OPTION?

No, unless you have a nonstatutory stock option which provides otherwise, 
generally only you may exercise your CompuRAD Option during your lifetime.  
You may not transfer your option during your lifetime, but you may be able to 
provide for the transfer of the option upon your death in your will.  Under 
certain circumstances, a nonstatutory stock option may be transferred to your 
former spouse pursuant to a domestic relations order.

14. CAN I SELL THE STOCK I RECEIVE FROM EXERCISING MY COMPURAD OPTION RIGHT 
AWAY?

Generally, yes.  The stock you receive upon exercise of your CompuRAD Option 
is freely tradeable in most cases and will not bear any restrictive legends 
unless you are an insider of Lumisys.  See Question 20 if you are an insider 
of Lumisys.  If you exercise an incentive stock option, an immediate sale will 
have certain tax consequences of which you should be aware. See Question 26.  
If the terms of the option permit you to exercise your option before it is 
vested, you may not sell shares of stock which Lumisys still has the right to 
repurchase.

15. IF I AM AWARE OF IMPORTANT NON-PUBLIC INFORMATION, CAN I SELL MY STOCK 
BEFORE THIS NEWS IS DISCLOSED TO THE PUBLIC?  FOR EXAMPLE, IF I KNOW LUMISYS 
IS HAVING SIGNIFICANT PROBLEMS OR THAT LUMISYS IS ABOUT TO ACQUIRE A 
COMPETITOR, CAN I SELL MY STOCK BEFORE LUMISYS PUTS OUT A PRESS RELEASE?

No.  If you are aware of important inside information, you must not sell 
shares of Lumisys's stock, whether received upon exercise of an option or 
otherwise, before dissemination of the information to the public.  Basically, 
"inside information" is information that is both very important (material) and 
non-public (not disclosed through press releases, newspaper articles or 
otherwise to the public which buys and sells securities).  Whether information 
is material will depend on the specific circumstances.  A general test is 
whether dissemination of the information to the public would be likely to 
affect the market price of Lumisys's stock or would be likely to be considered 
important by people who are considering whether to buy or sell Lumisys's 
stock.  Certainly if the information makes you want to buy or sell, it would 
probably have the same effect on others.  Material information may include 
projections, estimates or proposals.  

If you are contemplating selling your stock and think you might have "inside 
information," you must discuss your possible sale with the Chief Financial 
Officer of Lumisys.  If, after this discussion, it is determined that the 
information is in fact inside information, you must wait to sell your stock 
until after the information has been made public.

16. DO I PAY A COMMISSION WHEN I EXERCISE MY COMPURAD OPTION OR SELL THE 
STOCK?

You pay no commission on the exercise of your CompuRAD Option.  Generally, to 
sell your stock you must take the stock certificate to a stock broker, who can 
arrange for its sale.  You can expect to be charged a commission if you use a 
stock broker.  Lumisys will not buy from you, sell on your behalf or assist 
you in selling stock which you have purchased under the Plan.  Insiders are 
subject to restrictions on the sale of their stock.  See Question 20.

17. HOW CAN I MAKE A GIFT OF THE STOCK I RECEIVE UPON EXERCISING MY COMPURAD 
OPTION?

You may make a gift of stock by delivering the stock certificate, with the 
transfer block on the back filled in and signed with the signature guaranteed 
by a bank or stock broker (or by delivering the stock certificate together 
with an "assignment separate from certificate" filled in, signed and the 
signature similarly guaranteed) to the recipient of the gift.  The recipient 
may then send the certificate and associated paperwork to Lumisys' transfer 
agent to have the stock certificate transferred to the recipient's name.  The 
Vice President, Finance of Lumisys can provide you with the address of the 
transfer agent.  If you have a brokerage account, your broker will generally 
be willing to take care of the mechanics of transfer.  Please note that a gift 
of stock acquired upon exercise of an incentive stock option may result in a 
"disqualifying disposition" for tax purposes.  See Question 26.

18. DOES LUMISYS PAY DIVIDENDS ON ITS COMMON STOCK?

Lumisys currently is not paying dividends on its common stock and presently 
intends to continue this policy in order to retain earnings for use in its 
business.

19. DOES THE PLAN HAVE ANY OF THE SAME BENEFITS AS A QUALIFIED RETIREMENT PLAN 
(INCLUDING A 401(K) PLAN) AND WILL MY PARTICIPATION IN THE PLAN AFFECT MY 
PARTICIPATION IN A 401(K) PLAN?

The Plan is not a qualified retirement plan and, therefore, does not have the 
same tax deferral benefits, nor is the Plan subject to any provisions of the 
Employee Retirement Income Security Act of 1974 ("ERISA").  Your participation 
in the Plan does not affect your ability to participate in any 401(k) plan of 
Lumisys.

20. DO SPECIAL RULES APPLY TO ME IF I AM OR BECOME AN INSIDER OF LUMISYS?

Yes.  If you are or become an insider, you should be aware of tax and 
securities laws which apply to grants of options to you and to your 
transactions in stock received upon the exercise of options.  You must comply 
with Lumisys's policy permitting insiders to sell shares only during certain 
"window" periods, and you are subject to special rules regarding the sale of 
Lumisys's stock, such as the limitations on the amount you can sell found in 
Rule 144 and the restrictions on timing of purchases and sales found in 
Section 16 of the Exchange Act.  If you need information about how Section 16 
or Rule 144 operates, you should contact Lumisys.  You must check with the 
Vice President, Finance of Lumisys before selling any shares.


                                 Part II

                 Tax Issues Relating to your CompuRAD Option


The information in this Part II and the examples in Part III respond to 
questions you may have about the United States federal tax consequences of 
your CompuRAD Option.  You should understand, however, that this tax 
information is not complete.  For example, it does not address state or local 
tax laws or the application of laws if you are subject to tax laws in other 
countries.  Furthermore, because tax laws and regulations may change, and 
interpretations of these laws and regulations can change the way the laws and 
regulations apply to you, this information may need to be updated after the 
issuance of this prospectus.  Therefore, you should consult with a tax advisor 
if you have questions relating to the tax consequences of your CompuRAD 
Option, and the sale of shares received under your option.

The following table should help you locate particular questions you may have 
with regard to the United States federal tax consequences of your 
participation in the Plan.

21. DO I HAVE TO PAY TAX WHEN I RECEIVE OR EXERCISE A NONSTATUTORY STOCK 
OPTION?

If you were granted a nonstatutory stock option, neither you nor CompuRAD paid 
a tax (or received a deduction) upon grant of your CompuRAD Option.  If you 
exercise your option when the market price of the stock is higher than the 
exercise price of your option, you generally will be required to pay tax on 
the "profit," that is, the difference between the exercise price and the 
market price of the stock on the date of exercise.  Your profit on the 
exercise will be characterized as ordinary income, and Lumisys will be 
entitled to a deduction for this amount.

22. WILL LUMISYS WITHHOLD THE AMOUNT OF TAXES DUE ON EXERCISE OF MY 
NONSTATUTORY STOCK OPTION?

If you are an employee, Lumisys can take a business expense deduction on the 
amount of the profit you receive upon exercise of your CompuRAD Option.  
However, only when an employee exercises a nonstatutory stock option is 
Lumisys required by the IRS to withhold United States federal income and 
employment taxes from the profit or to otherwise ensure that the tax due will 
be paid to the IRS.  Additional amounts usually will be withheld for state 
taxes.  With respect to nonemployees (such as consultants and non-employee 
directors), Lumisys is not obligated to withhold United States federal income 
tax and employment tax on any profit.  Payroll will be able to answer any 
questions you may have concerning withholding.

23. HOW MUCH TAX DO I PAY WHEN I SELL STOCK RECEIVED PURSUANT TO THE EXERCISE 
OF A NONSTATUTORY STOCK OPTION?

If you exercise your nonstatutory stock option when the exercise price is 
lower than the market price, you generally will pay tax on the difference 
between the two.  Upon the sale of your stock (or other taxable transfer), you 
generally will recognize a gain or loss equal to the difference between the 
sales price and the market price at the time of exercise.  Your gain or loss 
will be characterized as: 

     -  long-term if the stock was held for more than 18 months,

     -  mid-term if the stock was held for more than 12 months but not more 
than 18 months, or

     -  short-term if the stock was held for 12 months or less.

24. WHAT IS THE DIFFERENCE BETWEEN ORDINARY INCOME AND CAPITAL GAINS AND 
LOSSES FOR UNITED STATES FEDERAL INCOME TAX PURPOSES?

The maximum marginal tax rate applicable to ordinary income and short-term 
capital gains is 39.6%.  Currently, the maximum marginal tax rate is 20% for 
long-term capital gains (shares held more than 18 months) and 28% for mid-term 
capital gains (shares held more than 12 months but not more than 18 months).  
Even lower rates may apply to taxpayers in the 15% marginal income tax 
bracket.  Additionally, capital gains and losses are subject to certain other 
provisions of the Code not applicable to ordinary income.  Consult your tax 
advisor for more information regarding the rates that apply to you.

25. DO I HAVE TO PAY TAX WHEN I RECEIVE OR EXERCISE AN INCENTIVE STOCK OPTION?

If you were granted an incentive stock option, neither you nor CompuRAD paid a 
tax (or received a deduction) upon grant of your CompuRAD Option.  Except for 
the possible application of the alternative minimum tax (see Question 31), you 
will pay no tax upon exercise of your option until you dispose of the stock 
you acquire.  For exceptions to these general rules with respect to early 
exercise programs and, in some cases, insiders, see Question 32.

26. HOW IS MY PROFIT TAXED WHEN I DO DISPOSE OF THE STOCK RECEIVED ON EXERCISE 
OF AN INCENTIVE STOCK OPTION?  WHAT IF I LOSE MONEY?

How your profit or loss is characterized will depend on how much time passed 
after both the date the incentive stock option was granted and the date you 
exercised the option.

     -  If the date on which you dispose of the stock is at least two years 
from the date on which the option was granted and at least one year from the 
date on which you exercised the option, your entire gain or loss is 
characterized as mid-term or long-term capital gain or loss.

     -  If you dispose of your stock within two years from the date on which 
the option was granted or within one year from the date on which you exercised 
your option, a portion of your profit will be characterized as ordinary income 
and the transfer will be a "disqualifying disposition."

You should be aware that transfer of legal title to the stock received upon 
exercise of an incentive stock option in a transaction that is not a sale may 
still be taxable as a disposition of the stock.  Such transfers include most 
gifts, but do not include a transfer into joint ownership with right of 
survivorship if you remain one of the joint owners, a pledge or a transfer by 
bequest or inheritance, certain tax-free exchanges or certain transfers to a 
spouse or former spouse incident to a divorce.

The portion of your profit which is characterized as ordinary income upon a 
disqualifying disposition is equal to the lesser of:

     -  the difference between the market price of the stock on the date you 
exercised the option and the exercise price of the option or

     -  the difference between the sales price and the exercise price of the 
option.

Any profit you make over the amount characterized as ordinary income is 
characterized as capital gain, which will be long-term, mid-term or short-term 
depending on how long you held your stock.  For an example of how these rules 
are applied, see Example A in Part III.  If you lose money on the sale of the 
stock, you may be able to report the loss as a capital loss, which will be 
long-term or short-term depending on whether or not the stock was held for 
more than one year from the exercise date.

Different rules will apply if, under the Code, you would not be entitled to 
report a loss on the sale of your stock if you were to lose money on the sale. 
 For example, if you sell your stock to your spouse at a loss, you are not 
entitled to report the sale as a loss, and any subsequent tax consequences on 
the further disposition of the stock are determined under special rules that 
govern such situations.  If you sell your stock to your spouse, whether or not 
at a loss, you will be taxed on the difference between the market price of the 
stock on the exercise date and the exercise price.  Other dispositions of 
stock, described in the Code, may have similar consequences.

27. IS THERE ANY WITHHOLDING ON THE EXERCISE OF MY INCENTIVE STOCK OPTION OR 
THE SALE OF THE STOCK ACQUIRED ON EXERCISE?

Currently, there is no withholding required upon the exercise of an incentive 
stock option or on the sale of stock acquired on exercise.  Lumisys is 
generally required to report to the IRS any ordinary income recognized by you 
as a result of a sale which is a disqualifying disposition described in 
Question 26.  Lumisys may be required in the future to withhold taxes at the 
time you exercise an incentive stock option or dispose of stock acquired on 
exercise of the option.

28. DO I HAVE TO COMPLETE ANY LUMISYS FORMS AFTER I SELL MY STOCK?

Yes.  If you dispose of stock received pursuant to an incentive stock option 
within two years after the date the option was granted to you or within one 
year after you exercise your option, you should immediately notify Lumisys and 
provide certain details of such transaction on a form provided to you (or 
which is available from the Vice President, Finance of Lumisys).

29. WHAT ARE THE TAX CONSEQUENCES IF I USE SHARES I ALREADY OWN TO PAY THE 
EXERCISE PRICE OF MY NONSTATUTORY STOCK OPTION?

If you pay the exercise price of your nonstatutory stock option with shares of 
Lumisys which you already own, you will have a tax-free exchange of the 
previously held shares of stock for an equivalent number of the shares of 
stock received under the CompuRAD Option.  If you receive additional shares in 
the exchange, you will pay taxes on ordinary income equal to the difference 
between the market value (on the date of exercise) of such additional shares 
plus the amount of cash, if any, you paid upon exercise.

The tax basis and capital-gain holding period of the equivalent shares 
received under the option in the tax-free exchange will be the same as the tax 
basis and holding period of the shares used to pay the exercise price.  The 
tax basis of the additional shares you receive will equal the amount of 
ordinary income you had to report plus the amount of any cash paid on 
exercise, and your holding period for the additional shares will begin on the 
date of exercise.  For an example of how these rules are applied, see 
Example B in Part III.

30. WHAT ARE THE TAX CONSEQUENCES IF I USE SHARES I ALREADY OWN TO PAY THE 
EXERCISE PRICE OF AN INCENTIVE STOCK OPTION?

Under proposed IRS regulations, if you pay the exercise price of an incentive 
stock option, in whole or in part, with shares you already own, you are deemed 
to have made a tax-free exchange of the previously-held shares for an 
equivalent number of shares received under the CompuRAD Option.

However, ordinary income could be recognized (see Question 26) if the already 
owned shares were acquired upon exercise of an incentive stock option or under 
an employee stock purchase plan as defined in Section 423 of the Code and the 
exchange were treated as a disposition.  The exchange will be treated as a 
disposition if the already owned shares are exchanged within two years of the 
grant date of the option relating to the already owned shares or within one 
year after the exercise date.  The tax basis, holding periods and consequences 
of a subsequent disposition of the shares will depend on whether the shares 
disposed of are equivalent shares or additional shares received at the time of 
exercise ("additional shares").

For purposes of calculating any capital gain or loss upon a subsequent taxable 
disposition, your basis in the equivalent shares will be equal to your basis 
in the shares surrendered plus any ordinary income recognized by reason of the 
exchange, and the holding period of the surrendered shares will carry over to 
the equivalent shares.  However, for purposes of calculating any ordinary 
income on a subsequent disqualifying disposition, the amount treated as having 
been paid for the equivalent shares will be equal to their fair market value 
on the exercise date, and the holding period for such shares will begin on the 
exercise date.

It appears that your basis in any additional shares, for purposes of 
calculating any capital gain upon a later disposition, will be the amount of 
cash, if any, used to pay any part of the exercise price.  For purposes of 
calculating any ordinary income upon a disqualifying disposition of the 
additional shares, the amount treated as having been paid for the additional 
shares will be the amount of cash, if any, used to pay any part of the 
exercise price.  The holding period for the additional shares will begin on 
the exercise date for all purposes.

If there is a disqualifying disposition of shares acquired upon exercise of an 
incentive stock option with stock, the shares with the lowest basis will be 
treated as having been disposed of first.  For an example of how these rules 
are applied, see Example C in Part III.

31. WHAT ARE THE TAX CONSEQUENCES OF MY EXERCISE OF AN INCENTIVE STOCK OPTION 
IF I AM SUBJECT TO THE ALTERNATIVE MINIMUM TAX?

The alternative minimum tax is a separately computed tax equal to 26% of so 
much of your "alternative minimum taxable income" up to $175,000 ($87,500 in 
the case of a married taxpayer filing a separate return) as exceeds a 
specified exemption amount plus 28% on any additional alternative minimum 
taxable income.  The alternative minimum tax is imposed only if and to the 
extent you would pay more tax if your taxes are computed pursuant to the 
alternative minimum tax rules than the tax you would pay if computed in the 
regular manner.  The alternative minimum tax takes into account what are 
called tax preference items and other adjustments that are not taken into 
account when calculating taxes in the regular manner.  One of the adjustments 
is the inclusion in alternative minimum taxable income of the difference 
between the exercise price of an incentive stock option and the market price 
of the stock on the exercise date, if that amount constitutes a profit.  If 
you pay alternative minimum tax upon exercise of an incentive stock option, 
you are entitled to a credit against regular tax (but not alternative minimum 
tax) in later years.  When you sell the stock, you are allowed, for purposes 
of calculating your alternative minimum tax in the year of sale, to decrease 
the profit by the adjustment amount previously included in your alternative 
minimum taxable income in the year of exercise.

If you are subject to a risk for forfeiture (see Question 32) the amount of 
the adjustment will be calculated using market prices on the dates the 
forfeiture lapses rather than the date you exercise the option, and the 
adjustment must be made in the year in which the risk of forfeiture 
disappears.  It may be possible, however, to make a valid election under 
Section 83(b) of the Code within 30 days of the exercise date to have the 
market price on the exercise date be the price used in calculating your 
alternative minimum tax and to make the adjustment in the year of exercise.  
However, if a Section 83(b) election is made, there may be implications for 
purposes of calculating ordinary income, if any, if there is a disqualifying 
disposition (see Questions 26 and 32).

32. ARE THERE ANY SPECIAL TAX RULES WHICH APPLY TO ME IF LUMISYS HAS THE RIGHT 
TO REPURCHASE MY STOCK AFTER I EXERCISE MY COMPURAD OPTION OR IF I AM SUBJECT 
TO SECTION 16?

Yes.  If Lumisys has the right to repurchase your stock after you exercise 
your CompuRAD Option, generally it is because, under the terms of your option, 
you were allowed to exercise all of your option, even the unvested portion.  
In this situation Lumisys will retain a right to repurchase any unvested 
shares until they vest.  If Lumisys has the right to repurchase your stock 
after you exercise your option, your stock is subject to what is called a 
"risk of forfeiture."

There is a small chance that stock received upon exercise of an option within 
six months of the grant date may also be subject to a risk of forfeiture if 
you are an insider at that time.  You should consult with your personal tax 
advisor if this applies to you.  You are subject to Section 16 only if you are 
an insider.  See Question 20.  If there is a risk of forfeiture, the amount of 
ordinary income you must report and the time at which you must report your 
income may be different than described above.  The special tax rules 
applicable to nonstatutory stock options and incentive stock options where a 
"risk of forfeiture" is present are as follows:

Nonstatutory Stock Option.

In the case of stock issued pursuant to a nonstatutory stock option and 
subject to a risk of forfeiture, you do not recognize ordinary income on the 
date of exercise but, instead, you will recognize ordinary income on the 
date(s) the risk of forfeiture with respect to the shares disappears (e.g.,  
the date Lumisys no longer has the right to repurchase the stock or the date 
you are not liable to forfeiture under the Exchange Act).  The amount of such 
ordinary income is the excess, if any, of the market price of the stock on the 
date(s) the risk of forfeiture disappears, over the exercise price paid for 
such shares.

When you later sell your shares, any additional gain or any loss will be 
characterized as capital gain or loss, which will be long-term, mid-term or 
short-term depending on how long you held your stock.  For an example of how 
these rules are applied, see Example D in Part III.

The recently widened gap between the 20% capital gain rate and the 39.6% 
ordinary income tax rate (plus the unlimited medicare 1.45% tax payable by 
both the optionee and Lumisys, that is, 2.9%) make the filing of a Section 
83(b) election to avoid this result more attractive.  You can file what is 
called a Section 83(b) election within 30 days after the exercise of the 
option and report ordinary income equal to the difference, if any, between the 
market price and the exercise price on the date of exercise.  When you later 
sell your shares, any additional gain or any loss will be characterized as 
capital gain or loss, which will be long-term, mid-term or short-term 
depending on how long you held your stock.  You should be aware, however, that 
if you file a Section 83(b) election, the market price of the shares may not 
increase enough to justify the early tax payment.  In addition, if you 
subsequently forfeit your profit from the shares because, for example, you 
leave Lumisys and Lumisys repurchases the shares at cost, there will be no 
offsetting tax deduction (that is, you will not be able to report the amount 
you paid in taxes as a loss on the stock) and you will not get a refund of any 
of the tax paid).

Incentive Stock Option.

If stock you receive pursuant to the exercise of an incentive stock option is 
subject to a risk of forfeiture and you dispose of the stock after the risk of 
forfeiture lapses in a disqualifying disposition (see Question 26), the amount 
of ordinary income you must report is calculated differently.  In this case, 
the amount of ordinary income generally is equal to the lesser of:

     -  the excess, if any, of the market price of the stock on the date(s) 
the risk of forfeiture disappears over the exercise price paid for such stock, 
or
 
     -  the profit, if any, on the sale of the stock.

If your profit is more than the amount that must be reported as ordinary 
income, then the remainder of the profit is characterized as capital gain, 
which will be long-term, mid-term or short-term depending on how long you held 
your stock.  For an example of how these rules are applied, see Example E in 
Part III.  If you wish to avoid this result, you may be able to make the 
Section 83(b) election discussed earlier in this question.  If the election is 
filed, your ordinary income should be calculated in the manner described in 
Question 26.

Please contact the Vice President, Finance of Lumisys for further information 
and the form of election if you think you should be filing a Section 83(b) 
election.  Remember that this must be done within 30 days after you exercise 
your option.  Filing a Section 83(b) election also may affect your alternative 
minimum tax liability, if any (see Question 31).

33. WHAT HAPPENS IF THE VESTING OF MY COMPURAD OPTION ACCELERATES UPON A 
CHANGE OF CONTROL?

If there is a change in control of Lumisys (see Question 9), payments received 
by certain persons that are contingent upon the change in control may 
constitute "parachute payments."  If, by reason of such change in control, the 
exercisability of outstanding CompuRAD Options is accelerated, the value of 
the acceleration is added to other contingent payments, if any, in determining 
whether the person has received "excess parachute payments."  In general, if a 
person receives excess parachute payments, an excise tax equal to 20% of the 
amount of such excess parachute payments is imposed on the person and Lumisys 
does not receive a deduction for such amount.



                                 PART III

                                 EXAMPLES


EXAMPLE A (QUESTION 26):  DISQUALIFYING DISPOSITION OF AN INCENTIVE STOCK 
OPTION

Assume for the purposes of this example only that you were granted an 
incentive stock option on April 1, 1997 for 10 shares at an exercise price of 
$8 per share.  You exercise the option on April 1, 1998 when the market price 
is $10 per share, and you sell the stock on October 1, 1998 when the market 
price is $9 per share for a $10 aggregate gain.  Because you did not hold the 
stock until a date which is at least two years after the grant date and one 
year from the exercise date, all or a portion of your gain is ordinary income. 
 The amount of ordinary income per share in this case is equal to the lesser 
of (a) $10 (market price on exercise date) - $8 (exercise price) = $2 per 
share or (b) $9 (sale price) - $8 (exercise price) = $1 per share.  Therefore, 
the amount of ordinary income is equal to $1 per share, or $10 in the 
aggregate.


EXAMPLE B (QUESTION 29):	STOCK FOR STOCK EXERCISE OF A NONSTATUTORY STOCK 
OPTION

 Assume for the purposes of this example only that on April 1, 1997 you bought 
10 shares of stock on the open market when the market price was $6 per share. 
 On April 1, 1998, when the market price is $10 per share, you exercise a 
nonstatutory stock option to purchase 20 shares at an exercise price of $9 per 
share for an aggregate exercise price of $180.  Using all of your previously 
owned shares to pay $100 of the exercise price (10 shares x $10 market price), 
you pay $80 cash for the remainder of the exercise price.  On the date of 
exercise you are deemed to have a tax-free exchange of the 10 previously owned 
shares for 10 equivalent new shares.  You will also recognize ordinary income 
of $20, equal to the market price of the 10 additional new shares you receive, 
$100, minus the amount of cash you paid on exercise, $80.

If you sell all 20 shares which you received upon exercise of the option for 
$11 per share on June 1, 1998, you will recognize a $5 per share gain on the 
10 equivalent new shares ($11 per share - $6 per share, $6 per share being the 
purchase price of original shares), which will be mid-term capital gain 
because you are allowed to add the 12-month period which you held the original 
10 shares to the two-month period you held the 10 equivalent new shares.  You 
will also recognize a $10 aggregate gain on the 10 additional new shares, 
calculated as follows:  $110 (10 shares x $11 market price) minus the sum of 
(a) $80 (the amount of cash paid for the shares) and (b) $20 (the amount of 
income recognized upon exercise of the option).  This gain will be 
characterized as short-term capital gain because you held the stock for only 
two months.


EXAMPLE C (QUESTION 30):  STOCK FOR STOCK EXERCISE OF AN INCENTIVE STOCK 
OPTION

Assume for the purposes of this example only that you purchased 18 shares on 
the open market for $6 per share on April 1, 1997.  On May 1, 1997, when the 
market price is $10 per share, you exercise an incentive stock option to 
purchase 20 shares at an exercise price of $9 per share for an aggregate 
exercise price of $180, using your 18 previously owned shares to pay the 
exercise price.  On the exercise date, you are deemed to have made a tax-free 
exchange of the 18 previously owned shares for 18 equivalent new shares and to 
have acquired two additional new shares.

Because the shares delivered in payment of the exercise price were previously-
owned shares not acquired upon exercise of an incentive stock option or an 
employee stock purchase plan complying with Code Section 423, no disqualifying 
disposition occurred in the exchange and no ordinary income was recognized at 
the time of the exchange.  (However, you may recognize some alternative 
minimum taxable income.)  Therefore, the basis in the 18 equivalent new shares 
is the same as the basis of the original shares:  $6 per share.  However, for 
purposes of calculating ordinary income if there is a subsequent disqualifying 
disposition, the amount treated as having been paid for such equivalent new 
shares is equal to their fair market value on the exercise date ($10 per 
share).  The basis in the two additional new shares is $0.

If you sell 15 of the shares on April 1, 1999 at $11 per share, such shares 
are deemed to be sold in a disqualifying disposition because the disposition 
is less than one year after the May 1, 1999 exercise date.  Since the 
additional new shares have a lower basis ($0) than the equivalent new shares 
($6 per share), they will be treated as having been disposed of first 
(assuming you have not designated which of the shares are being sold).  
Therefore, you will be considered to have sold the two additional new shares 
and 13 of the equivalent new shares.

You will recognize no ordinary income with respect to the equivalent new 
shares since there is no difference between their fair market value on the 
exercise date and the amount treated as having been paid for such shares.  
However, you will recognize capital gain with respect to the equivalent new 
shares in the amount of $65 (13 shares x $5 per share, $5 per share being the 
$11 sale price minus the $6 basis).  Such capital gain will be long-term since 
the holding period for such equivalent new shares includes the holding period 
for the original shares exchanged therefor and is 20 months.

You will recognize ordinary income with respect to the additional new shares 
in the amount of $20 (2 shares x $10 per share, $10 per share being the $10 
fair market value on the exercise date minus the $0 basis).  You will 
recognize capital gain on such additional new shares in the amount of $2 (2 
shares x $1 per share, $1 per share being the $11 sale price minus the $10 
recognized as ordinary income).  Such capital gain will be short-term since 
the holding period for such additional new shares begins on the exercise date 
and is, therefore, only seven months.


EXAMPLE D (QUESTION 32):  RISKS OF FORFEITURE AND NONSTATUTORY STOCK OPTIONS

Assume for the purposes of this example only that on April 1, 1997 you are 
granted a nonstatutory option to purchase 20 shares of stock for $8 per share. 
 You may exercise the option immediately, but Lumisys has the right to 
repurchase all of the stock at the price you paid for it if you leave Lumisys 
before July 1, 1998, 15 shares if you leave before October 1, 1997, 10 shares 
if you leave before January 1, 1998 and five shares if you leave before 
April 1, 1998.  On May 20, 1997 you exercise your option with respect to all 
of the shares when the market price is $10.  Normally you would owe tax on 
$40, the difference between the $160 aggregate exercise price and the $200 
aggregate market price on the date of exercise.  However, because all the 
shares are subject to a risk of forfeiture, you do not calculate the tax on 
May 20 but on each day that a risk of forfeiture disappears.  For example, 
assume that on July 1, 1997 the market price is $11 per share.  On that date 
the risk of forfeiture disappears with respect to five shares because Lumisys 
no longer has the right to repurchase five of your 20 shares.  Accordingly, 
tax is calculated as follows:

     Number of shares no longer subject to vesting                     5
     Exercise price of option                                        $ 8
     market price on July 1                                          $11
     Amount on which tax is due                                      $15
                                               ($3 per share x 5 shares)

On October 1, 1997, January 1, 1998 and April 1, 1998 you may owe additional 
tax depending on the market price of the stock on those days.

If the market price of the stock is higher on the date the risk of forfeiture 
lapses with respect to any block of shares than it is on the exercise date, 
you will end up paying more ordinary income tax with respect to such block of 
shares as a result of your exercise of the option than you would have if the 
stock you received upon exercise had not been subject to a risk of forfeiture 
and you owed tax only on the difference between the exercise price and the 
market price on the date of exercise.


EXAMPLE E (QUESTION 32):  RISKS OF FORFEITURE AND INCENTIVE STOCK OPTIONS

Assume for the purposes of this example only that on April 1, 1997 you 
received an incentive stock option for 15 shares at an exercise price per 
share of $10.  The terms of the option indicated that you vested in only five 
shares initially with the remainder of the shares vesting at a rate of five 
shares per quarter.  On May 1, 1997 you exercise the option when the stock is 
worth $10 per share.  You do not have to pay any tax at the time of exercise. 
 On July 1, 1997, when the first five shares of the remaining shares vest, the 
market price is $11 per share and on October 1, 1997, when the second five 
shares of the remaining shares vest, the market price is $9 per share.  On 
November 1, 1997 you sell the 15 shares when the market price is $12 per share 
for a total gain of $30 (15 x $2).  Because you did not hold the stock for at 
least one year from the exercise date and two years from the grant date, the 
sale is a disqualifying disposition.

To calculate the ordinary income from the disqualifying disposition, you first 
calculate the excess, if any, of the market price of the stock on the exercise 
date, or, if later, the date(s) the risk of forfeiture disappeared, over the 
exercise price of $10 (the spread).  The lesser of this amount or your actual 
gain on the purchase and sale represents the ordinary income you must 
recognize.

Exercise date                                             May 1, 1997
Number of shares not subject to vesting on exercise date            5
Exercise price per share                                          $10
market price per share on May 1, 1998                             $10
Spread per share on exercise date                                 -0-
Actual gain per share on purchase and sale                        $ 2
Lesser of spread on exercise date and gain                        -0-
Ordinary income per share on which tax is due                     -0-

Vesting date                                             July 1, 1997
Additional number of shares no longer subject to vesting            5
Exercise price per share                                          $10
market price per share on July 1, 1998                            $11
Spread per share on July 1, 1998                                  $ 1
Actual gain per share on purchase and sale                        $ 2
Lesser of spread when risk
of forfeiture disappears and actual gain                          $ 1
Ordinary income per share on which tax is due                     $ 1

Vesting date                                          October 1, 1997
Additional number of shares no longer subject to vesting            5
Exercise price per share                                          $10
market price per share on October 1, 1998                         $ 9
Spread per share on October 1, 1998                               -0-
Actual gain per share on purchase and sale                        $ 2
Lesser of spread when risk
of forfeiture disappears and actual gain                          -0-
Ordinary income per share on which tax is due                     -0-

There is an excess of the market price of the stock on the later of the 
exercise date or the date the risk of forfeiture lapsed, over the exercise 
price only with respect to the five shares which vest on July 1, 1998.  
Therefore, $5 of gain (5 shares x $1 per share) will be treated as ordinary 
income.  The remainder of the gain ($30 - $5 = $25) will be short-term capital 
gain.

          THIS DOCUMENT CONSTITUTES PART OF A PROSPECTUS COVERING
             SECURITIES THAT HAVE BEEN REGISTERED UNDER THE
                         SECURITIES ACT OF 1933.

               The date of this document is November 25, 1997


                       ________________________________

                  PROSPECTUS FOR OPTIONS GRANTED UNDER THE
                      COMPURAD, INC. STOCK OPTION PLAN
                       ASSUMED BY LUMISYS INCORPORATED
                       ________________________________


To Our Optionees:

As a result of the merger on November 25, 1997 of an affiliate of Lumisys 
Incorporated ("Lumisys") with and into CompuRAD, Inc. ("CompuRAD"), CompuRAD 
became a wholly owned subsidiary of Lumisys (the "Merger").  As part of the 
Merger, options originally granted to you by CompuRAD under the Stock Option 
Plan (the "Plan") have been assumed by Lumisys.  We are pleased with this 
opportunity to provide you with information regarding the option granted to 
you by CompuRAD (the "CompuRAD Options") under the Plan.  We believe that your 
CompuRAD Option is an important part of the benefits provided to you and hope 
you will take the time to review this information carefully.

Each CompuRAD Option assumed by Lumisys has been converted into an option to 
purchase that number of shares of Lumisys common stock determined by 
multiplying the number of shares of CompuRAD common stock for which you hold 
CompuRAD Options by 0.928 and rounding down to the nearest whole number (with 
cash, less the applicable exercise price, being payable for any fraction of a 
share).  The exercise price per share will be equal to the exercise price of 
the CompuRAD Options divided by 0.928 rounded up to the nearest cent.  The 
other terms of each CompuRAD Option, including tax status and vesting, will 
remain unchanged. 

We have divided our discussion of the Plan into three parts.  The first part 
of this document describes the terms of the Plan, which provides for the grant 
of nonstatutory stock options (options which do not have tax advantages).  The 
second and third parts of this document describe the tax consequences relating 
to your CompuRAD Option.

The following information and attached materials may not answer all the 
questions you have about the Plan or about Lumisys' assumption of the CompuRAD 
Options and are not intended to go into every detail.  The Vice President, 
Finance of Lumisys at (408) 733-6565 will be happy to answer further 
questions.  A copy of the Plan and an exercise form are attached at the end of 
this package.  If you wish to exercise your CompuRAD Option, you will need to 
complete the exercise form.  You may always obtain copies of the exercise form 
from Lumisys.

                         INFORMATION ABOUT LUMISYS

An important part of your CompuRAD Option is understanding Lumisys, its 
operations and its financial condition.  You can keep yourself informed about 
Lumisys by reviewing reports and other documents which Lumisys prepares for 
stockholders and the general public and which will be provided to you (as 
discussed below).  If you become a stockholder of Lumisys, you will be 
entitled to attend stockholder meetings and to vote in the election of 
directors and on other matters brought before the stockholders.

If you have not already received a copy of Lumisys's current annual report as 
a stockholder of Lumisys, this information  should be delivered to you with 
these materials.  Whether or not you have already received this information, 
you may always request a copy from Lumisys.

In addition,the United States federal securities laws require Lumisys to 
provide information about its business and financial status in annual reports 
commonly known as "10-Ks" and quarterly reports commonly known as "10-Qs."  
These reports are filed with the Securities and Exchange Commission (the 
"Commission").  In addition, if certain important corporate events occur 
during the year, Lumisys may file reports commonly known as "8-Ks."  Lumisys 
also prepares and files with the Commission a proxy statement in connection 
with its annual meeting of stockholders.  The proxy statement provides further 
information about Lumisys and its officers, directors and major stockholders. 
 From time to time Lumisys may also file other documents with the Commission 
as required by Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange 
Act of 1934, as amended (the "Exchange Act").

All of these documents constitute part of the information required by the 
securities laws to be provided or made available to you in connection with 
your CompuRAD Option; that is, these documents are incorporated by reference 
into these materials, which constitute the prospectus for the Plan.  For a 
copy of these documents, all of which are available without charge and upon 
written or oral request, please contact Dean MacIntosh, Vice President, 
Finance, of Lumisys.

1.  WHO DETERMINED WHETHER I RECEIVED AN OPTION AND THE TERMS OF MY OPTION AND 
HOW MANY SHARES OF COMMON STOCK IT COVERED?

The decision to grant an option to any particular individual was made by the 
CompuRAD Board of Directors (the "CompuRAD Board") or by a committee of the 
CompuRAD Board generally after review of input from management.  The Plan 
provided for the grant of options to employees, directors and consultants 
covering an aggregate of 500,000 shares of CompuRAD's common stock.  When the 
CompuRAD Board (or committee) granted your CompuRAD Option, it had the 
discretion to determine the terms of the option, including the number of 
shares the option covered.

The Lumisys Board of Directors (the "Lumisys Board") now administers the 
CompuRAD Options and has the power to interpret them.  Information about the 
current members of the Lumisys Board is provided in Lumisys' proxy statement 
for its last annual meeting.  You may obtain additional information about the 
administration of the CompuRAD Options by contacting the Vice President, 
Finance of Lumisys.

When administration of the CompuRAD Options is delegated to a committee, the 
Lumisys Board retains the right to revert authority to construe and interpret 
the options back to itself.  References to the Lumisys Board in this document 
should be construed as references to the committee, as applicable.

2.  MY COMPURAD OPTION IS A NONSTATUTORY STOCK OPTION.  WHAT IS THE DIFFERENCE 
BETWEEN AN INCENTIVE STOCK OPTION AND A NONSTATUTORY STOCK OPTION?

The Plan provided only for the grant of nonstatutory stock options which do 
not qualify for the potentially favorable tax treatment provided to the 
holders of incentive stock options under the Internal Revenue Code of 1986, as 
amended (the "Code").

Upon the exercise of your CompuRAD Option, you generally will be taxed based 
on the difference between the exercise price of your option and the fair 
market value of the stock on the date of exercise.  (See Question 21.)  Upon 
the exercise of an incentive stock option, on the other hand, an optionee is 
typically not subject to tax.  The deferral of the recognition of tax until 
the time of sale of the stock, as well as the possible treatment of the 
"spread" as capital gain, are the principal advantages of incentive stock 
options.  However, incentive stock options have certain limitations on their 
exercise price, terms, transferability and duration which are not applicable 
to your CompuRAD Option.

3.  HOW WAS THE EXERCISE PRICE OF MY COMPURAD OPTION DETERMINED?

The Plan provided that the CompuRAD Board set the exercise price for your 
option at the net book value of a share of CompuRAD common stock on the last 
day of the month prior to the grant date.  The exercise price for each share 
of Lumisys common stock now covered by your CompuRAD Option, as assumed by 
Lumisys, is the exercise price per share of CompuRAD stock under the option 
immediately before the Merger divided by 0.928, rounded up to the nearest 
cent.

4.  WHEN CAN I EXERCISE MY COMPURAD OPTION?

When the CompuRAD Board granted your CompuRAD Option, it also determined 
certain terms of the option, including the date or dates after which the 
option may be exercised.  You should check your option agreement to determine 
the date(s) on which your shares become exercisable, or "vest."  (However, 
your option may provide that you can exercise your option as to unvested 
shares subject to Lumisys's right to repurchase "unvested" shares.)  CompuRAD 
Options may have a term of 15 years, so you must exercise your option before 
it expires at the end of the 15-year period.  For example, if your option was 
granted on February 1, 1995 and has a full 15-year term, it must be exercised 
before February 1, 2010.  The terms of exercise of options are not required to 
be the same for every optionee.  (For example, each option may have a 
different vesting period or may tie acceleration of vesting to the achievement 
of certain performance goals.)  Please review your option grant carefully to 
be sure that you understand its specific terms and conditions.

5.  HOW DO I EXERCISE MY COMPURAD OPTION?

You exercise your CompuRAD Option by completing an option exercise form and 
delivering the form, together with payment of the exercise price (see 
Question 6 below), to the Vice President, Finance of Lumisys.  You can obtain 
option exercise forms from the Vice President, Finance.

6.  DO I HAVE TO PAY THE EXERCISE PRICE WITH CASH?

You may always pay the exercise price with cash.  However, your CompuRAD 
Option may provide that the exercise price also may be paid with other 
consideration (for example, by delivery to Lumisys of other unencumbered 
common stock of Lumisys you already own with a value equal to the aggregate 
option exercise price or according to a deferred payment or other 
arrangement).  You should review the terms of your option which describes 
specifically the manner in which the exercise price may by paid.  You may be 
able to do a cashless exercise through a broker.  See Question 7.

7.  I HAVE HEARD ABOUT CASHLESS EXERCISE PROGRAMS THROUGH BROKERS.  HOW DO 
THESE WORK?

Cashless exercise programs involve the delivery to a broker of a copy of your 
signed and completed option exercise form and your irrevocable instructions to 
Lumisys to deliver stock to be received upon exercise of the option to the 
broker rather than to you.  Under U.S. Treasury Regulation T, the broker can 
then deliver cash to Lumisys in payment of the exercise price and, in some 
cases, withholding taxes.  Lumisys then delivers the stock certificate to the 
broker.  After the stock is delivered to the broker, the stock can be 
maintained as margin stock in an account designated by you, or it can be sold 
pursuant to your instructions.  However, Lumisys will not participate in any 
Regulation T program which would cause stock certificates to be delivered to 
the broker before Lumisys has received payment for the exercise price or an 
irrevocable guarantee of payment from the sales proceeds.  You should contact 
the Vice President, Finance of Lumisys for information regarding the cashless 
exercise program.  If you are an "insider" when you exercise your CompuRAD 
Option, you should ensure that your cashless exercises are properly structured 
in order to avoid any violation of the prohibition against short sales by 
insiders found in Section 16(c) of the Exchange Act.  In general, "insiders" 
are officers, directors, and 10% stockholders of a publicly-traded company or 
an executive officer of a significant subsidiary of such a company.

8.  WILL I CONTINUE TO RECEIVE OPTIONS UNDER THE PLAN AS LONG AS I CONTINUE 
PROVIDING SERVICES TO LUMISYS?

No, the Lumisys Board cannot grant any additional options under the Plan.  
(Nevertheless, your CompuRAD Option will continue in effect and will be 
governed by the provisions of the Plan and the stock option agreement 
documenting your option.)  However, you may be eligible to receive an option 
under a Lumisys stock option plan.  Whether or not you receive options will 
depend on many factors, such as your performance, Lumisys's overall 
performance, the Lumisys Board's then current policy and the number of shares 
remaining in the Lumisys stock option plan.  You should note that Lumisys' 
assumption of your CompuRAD Option does not alter any right to terminate your 
employment at any time and for any reason, with or without cause, or your 
service as a consultant according to the terms of your consultant agreement.

9.  CAN THE TERMS OF MY COMPURAD OPTION BE CHANGED?

The Lumisys Board decides whether to change the terms of the CompuRAD Options 
but your option will not be adversely affected without your consent.  Usually 
options are amended to take into account changes in the tax or securities 
laws.  These changes may be presented to the stockholders of Lumisys for 
approval at Lumisys's annual meeting if tax, securities or other laws require 
approval of the changes.

If certain changes occur to Lumisys's capitalization, e.g., a stock split or 
stock dividend of its common stock, the Lumisys Board will appropriately 
adjust the exercise price and number of shares subject to your option.  If 
Lumisys merges with another company or undergoes certain other types of 
capital reorganizations (a "change in control"), then either the surviving 
corporation will assume your option (or substitute a similar option for your 
option) or the time during which your option may be exercised will be 
accelerated.  However, if exercisability and vesting are accelerated, your 
option will terminate if not exercised prior to such event.

10.  WHAT HAPPENS IF I LEAVE LUMISYS?

Whether you leave Lumisys (or an affiliate) voluntarily or your service is 
terminated, your right to exercise any vested portion of your CompuRAD Option 
generally will terminate three months after your last day of service with 
Lumisys.  However, the terms of your option may provide that it will terminate 
sooner than three months after termination of your service or that it may be 
exercised more than three months after such termination.  (If the option is an 
incentive stock option, it generally must be exercised within three months of 
the termination date or it will become a nonstatutory stock option.)  You 
should check your option agreement.  Usually, you will not be able to exercise 
any unvested portion of your option once you have left your employment or 
terminated your engagement as a consultant.

11.  WHAT IF I LEAVE LUMISYS BECAUSE OF DISABILITY?

If your service is terminated because of your disability, you should review 
the terms of your CompuRAD Option.  Generally, the option will terminate 12 
months after your last day of service with Lumisys as determined between you 
and Lumisys.  You should contact the Vice President, Finance of Lumisys if you 
have any questions regarding what constitutes a disability.

12.  WHAT ARE THE RIGHTS OF MY HEIRS UPON MY DEATH?

Your estate or persons having rights to your CompuRAD Option by will or by the 
laws of descent and distribution will have the right to exercise your option 
as to any vested portion of your option if you were still in service at the 
time of death or, if so provided in your option, you died within three months 
after your service was terminated for any reason.  Your option will specify 
the date by which the option must be exercised, which usually will be 12 
months after your death.

13.  CAN A RELATIVE OR FRIEND EXERCISE MY COMPURAD OPTION?

No, unless your CompuRAD Option provides otherwise or the transfer is approved 
in advance by formal resolution of the Lumisys Board, generally only you may 
exercise your option during your lifetime.  While you may not be able to 
transfer your option during your lifetime, you may provide for the transfer of 
the option upon your death in your will.  Under certain circumstances, your 
option may be transferred to your former spouse pursuant to a domestic 
relations order.

14.  CAN I SELL THE STOCK I RECEIVE FROM EXERCISING MY COMPURAD OPTION RIGHT 
AWAY?

Generally, yes.  The stock you receive upon exercise of your CompuRAD Option 
is freely tradeable in most cases and will not bear any restrictive legends 
unless you are an insider of Lumisys.  See Question 20 if you are an insider 
of Lumisys.  If the terms of the option permit you to exercise your option 
before it is vested, you may not sell shares of stock which Lumisys still has 
the right to repurchase.

15.  IF I AM AWARE OF IMPORTANT NON-PUBLIC INFORMATION, CAN I SELL MY STOCK 
BEFORE THIS NEWS IS DISCLOSED TO THE PUBLIC?  FOR EXAMPLE, IF I KNOW LUMISYS 
IS HAVING SIGNIFICANT PROBLEMS OR THAT LUMISYS IS ABOUT TO ACQUIRE A 
COMPETITOR, CAN I SELL MY STOCK BEFORE LUMISYS PUTS OUT A PRESS RELEASE?

No.  If you are aware of important inside information, you must not sell 
shares of Lumisys's stock, whether received upon exercise of an option or 
otherwise, before dissemination of the information to the public.  Basically, 
"inside information" is information that is both very important (material) and 
non-public (not disclosed through press releases, newspaper articles or 
otherwise to the public which buys and sells securities).  Whether information 
is material will depend on the specific circumstances.  A general test is 
whether dissemination of the information to the public would be likely to 
affect the market price of Lumisys's stock or would be likely to be considered 
important by people who are considering whether to buy or sell Lumisys's 
stock.  Certainly if the information makes you want to buy or sell, it would 
probably have the same effect on others.  Material information may include 
projections, estimates or proposals.

If you are contemplating selling your stock and think you might have "inside 
information," you must discuss your possible sale with the Chief Financial 
Officer of Lumisys.  If, after this discussion, it is determined that the 
information is in fact inside information, you must wait to sell your stock 
until after the information has been made public.

16.  DO I PAY A COMMISSION WHEN I EXERCISE MY COMPURAD OPTION OR I SELL THE 
STOCK?

You pay no commission on the exercise of your CompuRAD Option.  Generally, to 
sell your stock you must take the stock certificate to a stock broker, who can 
arrange for its sale.  You can expect to be charged a commission if you use a 
stock broker.  Lumisys will not buy from you, sell on your behalf or assist 
you in selling stock which you have purchased under the Plan.  Insiders are 
subject to restrictions on the sale of their stock.  See Question 20.

17.  HOW CAN I MAKE A GIFT OF THE STOCK I RECEIVE UPON EXERCISING MY COMPURAD 
OPTION?

You may make a gift of stock by delivering the stock certificate, with the 
transfer block on the back filled in and signed with the signature guaranteed 
by a bank or stock broker (or by delivering the stock certificate together 
with an "assignment separate from certificate" filled in, signed and the 
signature similarly guaranteed) to the recipient of the gift.  The recipient 
may then send the certificate and associated paperwork to Lumisys's transfer 
agent to have the stock certificate transferred to the recipient's name.  The 
Vice President, Finance of Lumisys can provide you with the address of the 
transfer agent.  If you have a brokerage account, your broker will generally 
be willing to take care of the mechanics of transfer.

18.  DOES LUMISYS PAY DIVIDENDS ON ITS COMMON STOCK?

Lumisys currently is not paying dividends on its common stock and presently 
intends to continue this policy in order to retain earnings for use in its 
business.

19.  DOES THE PLAN HAVE ANY OF THE SAME BENEFITS AS A QUALIFIED RETIREMENT 
PLAN (INCLUDING A 401(K) PLAN) AND WILL MY PARTICIPATION IN THE PLAN AFFECT MY 
PARTICIPATION IN A 401(K) PLAN?

The Plan is not a qualified retirement plan and, therefore, does not have the 
same tax deferral benefits, nor is the Plan subject to any provisions of the 
Employee Retirement Income Security Act of 1974 ("ERISA").  Your participation 
in the Plan does not affect your ability to participate in any 401(k) plan of 
Lumisys.

20.  DO SPECIAL RULES APPLY TO ME IF I AM OR BECOME AN INSIDER OF LUMISYS?

Yes.  If you are or become an insider, you should be aware of tax and 
securities laws which apply to grants of options to you and to your 
transactions in stock received upon the exercise of options.  You must comply 
with Lumisys's policy permitting insiders to sell shares only during certain 
"window" periods, and you are subject to special rules regarding the sale of 
Lumisys's stock, such as the limitations on the amount you can sell found in 
Rule 144 and the restrictions on timing of purchases and sales found in 
Section 16 of the Exchange Act.  If you need information about how Section 16 
or Rule 144 operates, you should contact Lumisys.  You must check with the 
Vice President, Finance of Lumisys before selling any shares.


                                 PART II

               TAX ISSUES RELATING TO YOUR COMPURAD OPTION


The information in this Part II and the examples in Part III respond to 
questions you may have about the United States federal tax consequences of 
your CompuRAD Option.  You should understand, however, that this tax 
information is not complete.  For example, it does not address state or local 
tax laws or the application of laws if you are subject to tax laws in other 
countries.  Furthermore, because tax laws and regulations may change, and 
interpretations of these laws and regulations can change the way the laws and 
regulations apply to you, this information may need to be updated after the 
issuance of this prospectus.  Therefore, you should consult with a tax advisor 
if you have questions relating to the tax consequences of your CompuRAD Option 
and the sale of shares received under your option.

The following table should help you locate particular questions you may have 
with regard to the United States federal tax consequences of your option.


                                                    Relevant

          golden parachute payments                       27


21.  DO I HAVE TO PAY TAX WHEN I RECEIVE OR EXERCISE MY COMPURAD OPTION?

Neither you nor CompuRAD paid a tax (or received a deduction) upon grant of 
your CompuRAD Option.  If you exercise your option when the market price of 
the stock is higher than the exercise price of your option, you generally will 
be required to pay tax on the "profit," that is, the difference between the 
exercise price and the market price of the stock on the date of exercise.  
Your profit on the exercise will be characterized as ordinary income, and 
Lumisys will be entitled to a deduction for this amount.

22.  WILL LUMISYS WITHHOLD THE AMOUNT OF TAXES DUE ON EXERCISE OF MY COMPURAD 
OPTION?

Lumisys can take a business expense deduction on the amount of the profit you 
receive upon exercise of your CompuRAD Option.  However, only when an employee 
exercises an option is Lumisys required by the IRS to withhold United States 
federal income and employment taxes from the profit or to otherwise ensure 
that the tax due will be paid to the IRS.  Additional amounts usually will be 
withheld for state taxes.  With respect to nonemployees (such as consultants 
and non-employee directors), Lumisys is not obligated to withhold United 
States federal income tax and employment tax on any profit.  Payroll will be 
able to answer any questions you may have concerning withholding.

23.  HOW MUCH TAX DO I PAY WHEN I SELL STOCK RECEIVED PURSUANT TO THE EXERCISE 
OF MY COMPURAD OPTION?

If you exercise your CompuRAD Option when the exercise price is lower than the 
market price, you generally will pay tax on the difference between the two.  
Upon the sale of your stock (or other taxable transfer), you generally will 
recognize a gain or loss equal to the difference between the sales price and 
the market price at the time of exercise.  Your gain or loss will be 
characterized as:  

     -  long-term if the stock was held for more than 18 months,

     -  mid-term if the stock was held for more than 12 months but not more 
        than 18 months, or

     -  short-term if the stock was held for 12 months or less.

24.  WHAT IS THE DIFFERENCE BETWEEN ORDINARY INCOME AND CAPITAL GAINS AND 
LOSSES FOR UNITED STATES FEDERAL INCOME TAX PURPOSES?

The maximum marginal tax rate applicable to ordinary income and short-term 
capital gains is 39.6%.  Currently, the maximum marginal tax rate is 20% for 
long-term capital gains and 28% for mid-term capital gains.  Even lower rates 
may apply to taxpayers in the 15% marginal income tax bracket.  Additionally, 
capital gains and losses are subject to certain other provisions of the Code 
not applicable to ordinary income.  Consult your tax advisor for more 
information regarding the rates that apply to you.

25.  WHAT ARE THE TAX CONSEQUENCES IF I USE SHARES I ALREADY OWN TO PAY THE 
EXERCISE PRICE OF MY COMPURAD OPTION?

If you pay the exercise price of your CompuRAD Option with shares of Lumisys 
which you already own, you will have a tax-free exchange of the previously 
held shares of stock for an equivalent number of the shares of stock received 
under the option.  If you receive additional shares in the exchange, you will 
pay taxes on ordinary income equal to the difference between the market value 
(on the date of exercise) of such additional shares plus the amount of cash, 
if any, you paid upon exercise.

The tax basis and capital-gain holding period of the equivalent shares 
received under the option in the tax-free exchange will be the same as the tax 
basis and holding period of the shares used to pay the exercise price.  The 
tax basis of the additional shares you receive will equal the amount of 
ordinary income you had to report plus the amount of any cash paid on 
exercise, and your holding period for the additional shares will begin on the 
date of exercise.  For an example of how these rules are applied, see 
Part III.

26.  ARE THERE ANY SPECIAL TAX RULES WHICH APPLY TO ME IF I AM SUBJECT TO 
SECTION 16?

Yes.  There is a small chance that stock received upon exercise of a CompuRAD 
Option by an insider within six months of the grant date may be subject to a 
risk of forfeiture.  You should consult with your personal tax advisor if this 
applies to you.  If there is a risk of forfeiture, the amount of ordinary 
income you must report and the time at which you must report your income may 
be different than described above.  You would not recognize ordinary income on 
the date of exercise but, instead, you would recognize ordinary income on the 
date(s) the risk of forfeiture with respect to the shares disappears (e.g., 
the date you are not liable to forfeiture under the Exchange Act).  The amount 
of such ordinary income is the excess, if any, of the market price of the 
stock on the date(s) the risk of forfeiture disappears, over the exercise 
price paid for such shares.  When you later sell your shares, any additional 
gain or any loss will be characterized as capital gain or loss, which will be 
long-term, mid-term or short-term depending on how long you held your stock.  
For an example of how these rules are applied, see Example B in Part III.

If you wish to avoid this result, you can file what is called a Section 83(b) 
election within 30 days after the exercise of the option and report ordinary 
income equal to the difference, if any, between the market price and the 
exercise price on the date of exercise.  When you later sell your shares, any 
additional gain or any loss will be characterized as capital gain or loss, 
which will be long-term, mid-term or short-term depending on how long you held 
your stock.

Please contact the Vice President, Finance of Lumisys for further information 
and the form of election if you think you should be filing a Section 83(b) 
election.  Remember that this must be done within 30 days after you exercise 
your option.

27.  WHAT HAPPENS IF THE VESTING OF MY COMPURAD OPTION ACCELERATES UPON A 
CHANGE OF CONTROL?

If there is a change in control of Lumisys (see Question 9), payments received 
by certain persons that are contingent upon the change in control may 
constitute "parachute payments."  If, by reason of such change in control, the 
exercisability of outstanding CompuRAD Options is accelerated, the value of 
the acceleration is added to other contingent payments, if any, in determining 
whether the person has received "excess parachute payments."  In general, if a 
person receives excess parachute payments, an excise tax equal to 20% of the 
amount of such excess parachute payments is imposed on the person and Lumisys 
does not receive a deduction for such amount.


                                 PART III

                                 EXAMPLE

QUESTION 25:  STOCK FOR STOCK EXERCISES OF A NONSTATUTORY STOCK OPTION


Assume for the purposes of this example only that on April 1, 1998 you bought 
10 shares of stock on the open market when the market price was $6 per share. 
 On April 1, 1999, when the market price is $10 per share, you exercise your 
CompuRAD Option to purchase 20 shares at an exercise price of $9 per share for 
an aggregate exercise price of $180.  Using all of your previously owned 
shares to pay $100 of the exercise price (10 shares x $10 market price), you 
pay $80 cash for the remainder of the exercise price.  On the date of exercise 
you are deemed to have a tax-free exchange of the 10 previously owned shares 
for 10 equivalent new shares.  You will also recognize ordinary income of $20, 
equal to the market price of the 10 additional new shares you receive, $100, 
minus the amount of cash you paid on exercise, $80.

If you sell all 20 shares which you received upon exercise of the option for 
$11 per share on June 1, 1999, you will recognize a $5 per share gain on the 
10 equivalent new shares ($11 per share - $6 per share, $6 per share being the 
purchase price of original shares), which will be mid-term capital gain 
because you are allowed to add the 12-month period which you held the original 
10 shares to the two-month period you held the 10 equivalent new shares.  You 
will also recognize a $10 aggregate gain on the 10 additional new shares, 
calculated as follows:  $110 (10 shares x $11 market price) minus the sum of 
(a) $80 (the amount of cash paid for the shares) and (b) $20 (the amount of 
income recognized upon exercise of the option).  This gain will be 
characterized as short-term capital gain because you held the stock for only 
two months.


Example B (Question 26):  Risks of Forfeiture and Nonstatutory Stock Options

Assume for the purposes of this example only that on April 1, 1997 you are 
granted a nonstatutory option to purchase 20 shares of stock for $8 per share. 
 You may exercise the option immediately, but Lumisys has the right to 
repurchase all of the stock at the price you paid for it if you leave Lumisys 
before July 1, 1998, 15 shares if you leave before October 1, 1997, 10 shares 
if you leave before January 1, 1998 and five shares if you leave before 
April 1, 1998.  On May 20, 1997 you exercise your option with respect to all 
of the shares when the market price is $10.  Normally you would owe tax on 
$40, the difference between the $160 aggregate exercise price and the $200 
aggregate market price on the date of exercise.  However, because all the 
shares are subject to a risk of forfeiture, you do not calculate the tax on 
May 20 but on each day that a risk of forfeiture disappears.  For example, 
assume that on July 1, 1997 the market price is $11 per share.  On that date 
the risk of forfeiture disappears with respect to five shares because Lumisys 
no longer has the right to repurchase five of your 20 shares.  Accordingly, 
tax is calculated as follows:

      Number of shares no longer subject to vesting                    5
      Exercise price of option                                       $ 8

On October 1, 1997, January 1, 1998 and April 1, 1998 you may owe additional 
tax depending on the market price of the stock on those days.

If the market price of the stock is higher on the date the risk of forfeiture 
lapses with respect to any block of shares than it is on the exercise date, 
you will end up paying more ordinary income tax with respect to such block of 
shares as a result of your exercise of the option than you would have if the 
stock you received upon exercise had not been subject to a risk of forfeiture 
and you owed tax only on the difference between the exercise price and the 
market price on the date of exercise.
