Item 5.  Other Events.

This Current Report on Form 8-K (the "Report") contains forward-
looking statements within the meaning of Section 27A of the 
Securities Act of 1933, as amended, and Section 21E of the 
Securities Exchange Act of 1934, as amended.  The forward-looking 
statements contained herein involve risks and uncertainties, 
including those relating to the possible inability to complete the 
merger transaction involving the Company and CompuRAD, Inc., a 
Delaware corporation ("CompuRAD"), as scheduled, if at all, and 
those associated with the ability of the combined company to 
achieve the anticipated benefits of the merger.   Actual results 
and developments may differ materially from those described or 
incorporated by reference in this Report.  For more information 
about the Company and risks arising when investing in the Company, 
investors are directed to the Company's most recent report on Form 
10-K as filed with the Securities and Exchange Commission (the 
"SEC").

On September 28, 1997, the Company entered into an Agreement and 
Plan of Merger and Reorganization (the "Reorganization 
Agreement"), among the Company, CompuRAD and SAC Acquisition 
Corporation, a Delaware corporation and a wholly-owned subsidiary 
of the Company ("Merger Sub").  The description contained in this 
Item 5 of the transactions contemplated by the Reorganization 
Agreement is qualified in its entirety by reference to the full 
text of the Reorganization Agreement, a copy of which is attached 
to this Report as Exhibit 2.  

The Reorganization Agreement contemplates that, subject to the 
satisfaction of certain conditions set forth therein, including 
the approval and adoption of the Reorganization Agreement by the 
requisite vote of CompuRAD's stockholders and the approval of the 
issuance of Company common stock in the Merger by the Company's 
stockholders, Merger Sub would be merged into CompuRAD.  As a 
result of the merger of Merger Sub into CompuRAD (the "Merger"), 
CompuRAD would become a wholly-owned subsidiary of the Company.  
Under the terms of the Reorganization Agreement, each outstanding 
share of CompuRAD's common stock would be converted into 0.928 of 
a share of the Company's common stock. The Merger is intended to 
be a tax-free reorganization under the Internal Revenue Code of 
1986, as amended, and is intended to be accounted for as a pooling 
of interests.

On September 29, 1997, the Company and CompuRAD issued a joint 
press release relating to the execution of the Reorganization 
Agreement.  A copy of the press release is attached hereto as 
Exhibit 99.1 and is incorporated herein by reference.

In connection with the execution of the Reorganization Agreement, 
certain directors of CompuRAD, who collectively beneficially own 
approximately 41% of the outstanding shares of common stock of 
CompuRAD, entered into Voting Agreements pursuant to which each 
such director agreed to vote his shares in favor of the Merger.  
The description contained in this Item 5 of the transactions 
contemplated by the Voting Agreement is qualified in its entirety 
by reference to the full text of the Voting Agreement, the form of 
which is attached to this Report as Exhibit 99.2.

A registration statement relating to the Company common stock to 
be issued in connection with the Merger has not yet been filed 
with the SEC, nor has a proxy statement relating to a vote of 
CompuRAD's stockholders on the Merger or relating to a vote of the 
Company's stockholders on the issuance of Company common stock in 
the Merger been filed with the SEC.  The Company common stock may 
not be offered, nor may offers to acquire such stock be accepted, 
prior to the time such a registration statement becomes effective. 
This Report shall not constitute an offer to sell or the 
solicitation of an offer to buy any Company common stock or any 
other security, and shall not constitute the solicitation of any 
vote with respect to the Merger.

                            Agreement

      The parties to this Agreement, intending to be legally 
bound, agree as follows:


1.    Description of Transaction

      Merger of Merger Sub into the Company.  Upon the terms and 
subject to the conditions set forth in this Agreement, at the 
Effective Time (as defined in Section 1.3), Merger Sub shall be 
merged with and into the Company, and the separate existence of 
Merger Sub shall cease.  The Company will continue as the 
surviving corporation in the Merger (the "Surviving 
Corporation").

      1.1  Effect of the Merger.  The Merger shall have the 
effects set forth in this Agreement and in the applicable 
provisions of the Delaware General Corporation Law (the "DGCL").

      1.2  Closing; Effective Time.  The consummation of the 
transactions contemplated by this Agreement (the "Closing") shall 
take place at the offices of Cooley Godward llp, Five Palo Alto

on a date to be designated by Parent (the "Closing Date"), which 
(subject to the satisfaction or waiver of the conditions set 
forth in Sections 6 and 7) shall be no later than the tenth 
business day after the satisfaction of the latest to occur of the 
conditions set forth in Sections 6.4 and 7.4.  Contemporaneously 
with or as promptly as practicable after the Closing, a properly 
executed certificate of merger conforming to the requirements of 
the DGCL (the "Certificate of Merger") shall be filed with the 
Secretary of State of the State of Delaware.  The Merger shall 
take effect at the time the Certificate of Merger is filed with 
the Secretary of State of the State of Delaware (the "Effective 
Time").

      1.3  Certificate of Incorporation and Bylaws; Directors and 
Officers.  Unless otherwise determined by Parent prior to the 
Effective Time:

           (a)  the Certificate of Incorporation of the Surviving 
Corporation shall be amended and restated as of the Effective 
Time to conform to Exhibit B;

           (b)  the Bylaws of the Surviving Corporation shall be 
amended and restated as of the Effective Time to conform to the 
Bylaws of Merger Sub as in effect immediately prior to the 
Effective Time; and

           (c)  the directors and officers of the Surviving 
Corporation immediately after the Effective Time shall be the 
respective individuals who are directors and officers of Merger 
Sub immediately prior to the Effective Time.

                                   2

     1.5  Conversion of Shares.

           (a)  At the Effective Time, by virtue of the Merger 
and without any further action on the part of Parent, Merger Sub, 
the Company or any stockholder of the Company:

                (i)  any shares of Company Common Stock then held 
by the Company or any Subsidiary of the Company (or held in the 
Company's treasury) shall be canceled and retired and shall cease 
to exist, and no consideration shall be delivered in exchange 
therefor;

                (ii)  any shares of Company Common Stock then 
held by Parent, Merger Sub or any other Subsidiary of Parent 
shall be canceled and retired and shall cease to exist, and no 
consideration shall be delivered in exchange therefor;

                (iii)  except as provided in clauses "(i)" and 
"(ii)" above and subject to Sections 1.5(b), 1.5(d), 1.5(e) and 
1.8, each share of Company Common Stock then outstanding shall be 
converted into the right to receive 0.9280 of a share of Parent 
Common Stock, which shares shall have been registered under the 
Securities Act pursuant to a registration statement on Form S-4 
as described in Section 5.1 hereof; and

                (iv)  each share of the common stock, $0.001 par 
value per share, of Merger Sub then outstanding shall be 
converted into one share of common stock of the Surviving 
Corporation.

           (b)  The fraction of a share of Parent Common Stock 
specified in Section 1.5(a)(iii) (as such fraction may be 
adjusted in accordance with this Section 1.5(b)) is referred to 
as the "Exchange Ratio."  If, between the date of this Agreement 
and the Effective Time, the outstanding shares of Company Common 
Stock or Parent Common Stock are changed into a different number 
or class of shares by reason of any stock split, stock dividend, 
reverse stock split, reclassification, recapitalization or other 
similar transaction, then the Exchange Ratio shall be 
appropriately adjusted.
		
           (c)  In accordance with rules and regulations relating 
to pooling of interests accounting, if any shares of Company 
Common Stock outstanding immediately prior to the Effective Time 
are unvested or are subject to a repurchase option, risk of 
forfeiture or other condition under any applicable restricted 
stock purchase agreement or other agreement with the Company or 
under which the Company has any rights, then the shares of Parent 
Common Stock issued in exchange for such shares of Company Common 
Stock will also be unvested and subject to the same repurchase 
option, risk of forfeiture or other condition, and the 
certificates representing such shares of Parent Common Stock may 
accordingly be marked with appropriate legends.  The Company 
shall take all action that may be necessary to ensure that, from 
and after the Effective Time, Parent is entitled to exercise any 
such repurchase option or other right set forth in any such 
restricted stock purchase agreement or other agreement.

                                   3

           (d)  No fractional shares of Parent Common Stock shall 
be issued in connection with the Merger, and no certificates or 
scrip for any such fractional shares shall be issued.  Any holder 
of Company Common Stock who would otherwise be entitled to 
receive a fraction of a share of Parent Common Stock (after 
aggregating all fractional shares of Parent Common Stock issuable 
to such holder) shall, in lieu of such fraction of a share and, 
upon surrender of such holder's Company Stock Certificate(s) (as 
defined in Section 1.6), be paid in cash the dollar amount 
(rounded to the nearest whole cent), without interest, determined 
by multiplying such fraction by the closing price of a share of 
Parent Common Stock on the Nasdaq National Market System on the 
date the Merger becomes effective.

           (e)  If there are any Excess Company Merger Expenses 
(as defined in Section 8.3(a)), the Exchange Ratio shall be 
adjusted as follows:

New Exchange Ratio = Exchange Ratio x (Number of Company Common
                                       Stock to be exchanged in 
                                       the Merger + Company 
                                       options (as defined in 
                                       Section 2.3) and Company 
                                       Warrants (as defined in 
                                       Section 2.3)  x 7.50 - 
                                       Excess Company Merger 
                                       Expenses 
                                       7.50 x Number of Company 
                                       Common Stock to be 
                                       exchanged in the Merger + 
                                       Company Options and 
                                       Company Warrants)

      1.6  Closing of the Company's Transfer Books.  At the 
Effective Time: (a) all shares of Company Common Stock 
outstanding immediately prior to the Effective Time shall 
automatically be canceled and retired and shall cease to exist, 
and all holders of certificates representing shares of Company 
Common Stock that were outstanding immediately prior to the 
Effective Time shall cease to have any rights as stockholders of 
the Company; and (b) the stock transfer books of the Company 
shall be closed with respect to all shares of Company Common 
Stock outstanding immediately prior to the Effective Time.  No 
further transfer of any such shares of Company Common Stock shall 
be made on such stock transfer books after the Effective Time.  
If, after the Effective Time, a valid certificate previously 
representing any of such shares of Company Common Stock (a 
"Company Stock Certificate") is presented to the Exchange Agent 
(as defined in Section 1.7) or to the Surviving Corporation or 
Parent, such Company Stock Certificate shall be canceled and 
shall be exchanged as provided in Section 1.7.

                                   4

      1.7  Exchange of Certificates.

           (a)  On or prior to the Closing Date, Parent shall 
select a reputable bank or trust company to act as exchange agent 
in the Merger (the "Exchange Agent").  Promptly after the 
Effective Time, Parent shall deposit with the Exchange Agent (i) 
certificates representing the shares of Parent Common Stock 
issuable pursuant to this Section 1, and (ii) cash sufficient to 
make payments in lieu of fractional shares in accordance with 
Section 1.5(d).  The shares of Parent Common Stock and cash 
amounts so deposited with the Exchange Agent, together with any 
dividends or distributions received by the Exchange Agent with 
respect to such shares, are referred to collectively as the 
"Exchange Fund."

           (b)  As soon as reasonably practicable after the 
Effective Time, (but in any event within 10 business days 
thereafter) Parent shall cause the Exchange Agent to mail to the 
holders of Company Stock Certificates (i) a letter of transmittal 
in customary form and containing such provisions as Parent may 
reasonably specify (including a provision confirming that 
delivery of Company Stock Certificates shall be effected, and 
risk of loss and title to Company Stock Certificates shall pass, 
only upon delivery of such Company Stock Certificates to the 
Exchange Agent), and (ii) instructions for use in effecting the 
surrender of Company Stock Certificates in exchange for 
certificates representing Parent Common Stock.  Upon surrender of 
a Company Stock Certificate to the Exchange Agent for exchange, 
together with a duly executed letter of transmittal and such 
other documents as may be reasonably required by the Exchange 
Agent or Parent, (A) the holder of such Company Stock Certificate 
shall be entitled to receive in exchange therefor a certificate 
representing the number of whole shares of Parent Common Stock 
that such holder has the right to receive pursuant to the 
provisions of Section 1.5 (and cash in lieu of any fractional 
share of Parent Common Stock and any dividends or other 
distributions to which such holder is entitled pursuant to 
Section 1.7(c)), and (B) the Company Stock Certificate so 
surrendered shall be canceled.  Until surrendered as contemplated 
by this Section 1.7, each Company Stock Certificate shall be 
deemed, from and after the Effective Time, to represent only the 
right to receive shares of Parent Common Stock (and cash in lieu 
of any fractional share of Parent Common Stock and any dividends 
or other distributions to which such holder is entitled pursuant 
to Section 1.7(c)) as contemplated by Section 1.  If any Company 
Stock Certificate shall have been lost, stolen or destroyed, 
Parent may, in its discretion and as a condition precedent to the 
issuance of any certificate representing Parent Common Stock, 
require the owner of such lost, stolen or destroyed Company Stock 
Certificate to provide an appropriate affidavit and to deliver a 
bond (in such sum as Parent may reasonably direct) as indemnity 
against any claim that may be made against the Exchange Agent, 
Parent or the Surviving Corporation with respect to such Company 
Stock Certificate.

           (c)  No dividends or other distributions declared or 
made with respect to Parent Common Stock with a record date after 
the Effective Time shall be paid to the holder of any 
unsurrendered Company Stock Certificate with respect to the 
shares of Parent Common Stock represented thereby, and no cash 
payment in lieu of any fractional shares shall be paid to such 
holder, until such holder surrenders such Company Stock 

                                   5

Certificate in accordance with this Section 1.7 (at which time 
such holder shall be entitled, subject to the effect of 
applicable escheat or similar laws, to receive all such dividends 
and distributions, without interest).

           (d)  Any portion of the Exchange Fund that remains 
undistributed to holders of Company Stock Certificates as of the 
date 180 days after the date on which the Merger becomes 
effective shall be delivered to Parent upon demand, and any 
holders of Company Stock Certificates who have not theretofore 
surrendered their Company Stock Certificates in accordance with 
this Section 1.7 shall thereafter look only to Parent for 
satisfaction of any claims for Parent Common Stock, cash in lieu 
of fractional shares of Parent Common Stock and any dividends or 
distributions with respect to Parent Common Stock.

           (e)  Each of the Exchange Agent, Parent and the 
Surviving Corporation shall be entitled to deduct and withhold 
from any consideration payable or otherwise deliverable pursuant 
to this Agreement to any holder or former holder of Company 
Common Stock such amounts as may be required to be deducted or 
withheld therefrom under the Code or any provision of state, 
local or foreign tax law or under any other applicable Legal 
Requirement.  To the extent such amounts are so deducted or 
withheld, such amounts shall be treated for all purposes under 
this Agreement as having been paid to the Person to whom such 
amounts would otherwise have been paid.

           (f)  Neither Parent nor the Surviving Corporation 
shall be liable to any holder or former holder of Company Common 
Stock or to any other Person with respect to any shares of Parent 
Common Stock (or dividends or distributions with respect 
thereto), or for any cash amounts, delivered to any public 
official pursuant to any applicable abandoned property law, 
escheat law or similar Legal Requirement.

      1.8  Dissenting Shares.  

           (a)  Notwithstanding anything to the contrary 
contained in this Agreement, any shares of Company Common Stock 
outstanding immediately prior to the Effective Time that were not 
voted in favor of the Merger and are held by stockholders who 
have complied with the applicable provisions of Title 8, Section 
262 of the DGCL ("Dissenting Shares") shall not be converted into 
or represent the right to receive Parent Common Stock in 
accordance with Section 1.5(a)(iii) (or cash in lieu of 
fractional shares in accordance with Section 1.5(d)), and each 
holder of Dissenting Shares shall be entitled only to such rights 
as may be granted to such holder under Title 8, Section 262 of 
the DGCL.  From and after the Effective Time, a holder of 
Dissenting Shares shall not have and shall not be entitled to 
exercise any of the voting rights or other rights of a 
stockholder of the Surviving Corporation.  If any holder of 
Dissenting Shares shall fail to assert or perfect, or shall 
waive, rescind, withdraw or otherwise lose, such holder's right 
to dissent and obtain payment under Title 8, Section 262 of the 
DGCL, then such shares shall automatically be converted into and 
shall represent only the right to receive (upon the surrender of 
Company Stock Certificate(s) previously representing such shares) 
Parent Common Stock in accordance with Section 1.5(a)(iii) (and 
cash in lieu of any fractional share in accordance with Section 
1.5(d) and any dividends or other distributions to which such 
holder is entitled pursuant to Section 1.7(c)).

                                   6

           (b)  The Company: (i) shall promptly notify Parent in 
writing of any notice received by the Company of a stockholder's 
intent to demand payment for such stockholder's shares of Company 
Common Stock pursuant to Title 8, Section 262 of the DGCL, and 
shall promptly notify Parent in writing of any other notice, 
demand or instrument delivered to the Company pursuant to the 
DGCL; and (ii) shall give Parent's Representatives the 
opportunity to participate in all negotiations and proceedings 
with respect to any such notice, demand or instrument.  The 
Company shall not make any payment or settlement offer with 
respect to any such notice or demand unless Parent shall have 
consented in writing to such payment or settlement offer.

      1.9  Tax Consequences.  For federal income tax purposes, 
the Merger is intended to constitute a reorganization within the 
meaning of Section 368 of the Code.  The parties to this 
Agreement hereby adopt this Agreement as a "plan of 
reorganization" within the meaning of Sections 1.368-2(g) and 
1.368-3(a) of the United States Treasury Regulations.

      1.10  Accounting Consequences.  For financial reporting 
purposes, the Merger is intended to be accounted for as a 
"pooling of interests."  

      1.11  Further Action.  If, at any time after the Effective 
Time, any further action is determined by Parent to be necessary 
or desirable to carry out the purposes of this Agreement or to 
vest the Surviving Corporation with full right, title and 
possession of and to all rights and property of Merger Sub and 
the Company, the officers and directors of the Surviving 
Corporation and Parent shall be fully authorized (in the name of 
Merger Sub, in the name of the Company and otherwise) to take 
such action.

           (a)  Part 2.9(a)(i) of the Company Disclosure Schedule

licensed or otherwise made available to the Company by a third 
party (except for any Proprietary Asset that is licensed to the 
Company under any third party software license generally 
available to the public), and identifies the Contract under which 
such Proprietary Asset is being licensed or otherwise made

not developed jointly with any other Person any Company 
Proprietary Asset that is material to the business of the Company 
as currently conducted or proposed to be conducted with respect 
to which such other Person has any rights.  Except as set forth 
in Part 2.9(a)(v) of the Company Disclosure Schedule, there is no 
Company Contract (with the exception of end user license 
agreements in the form previously delivered by the Company to 
Parent) pursuant to which any Person has any right (whether or 
not currently exercisable) to use, license or otherwise exploit 
any Company Proprietary Asset.

           (b)  The Company has taken reasonable measures and 
precautions to protect and maintain the confidentiality, secrecy 
and value of all material Company Proprietary Assets (except 
Company Proprietary Assets whose value would be unimpaired by 
disclosure).  Without limiting the generality of the foregoing,  
except as set forth in Part 2.9(b) of the Company Disclosure 
Schedule, (i) all current and former employees of the Company who 
are or were involved in, or who have contributed to, the creation 
or development of any material Company Proprietary Asset have 

                                   13

executed and delivered to the Company an agreement (containing no 
exceptions to or exclusions from the scope of its coverage) that 
is substantially identical to the form of Non-Disclosure 
Agreement previously delivered by the Company to Parent, and (ii) 
all current and former consultants and independent contractors to 
the Company who are or were involved in, or who have contributed 
to, the creation or development of any material Company 
Proprietary Asset have executed and delivered to the Company an 
agreement (containing no exceptions to or exclusions from the 
scope of its coverage) that is substantially identical to the 
form of Consultant Confidential Information and Invention 
Assignment Agreement previously delivered to Parent.  No current 
or former employee, officer, director, stockholder, consultant or 
independent contractor has any valid right, claim or interest in 
or with respect to any Company Proprietary Asset.

           (c)  Except as set forth in Part 2.9(c) of the Company 
Disclosure Schedule:  (i) all trademarks, service marks, 
copyrights, and to the knowledge of the Company, patents, held by 
the Company are valid, enforceable and subsisting; (ii) none of 
the Company Proprietary Assets and no Proprietary Asset that is 
currently being developed by the Company (either by itself or 
with any other Person) infringes, misappropriates or conflicts 
with any Proprietary Asset owned or used by any other Person; 
(iii) none of the products that are or have been designed, 
created, developed, assembled, manufactured or sold by the 
Company is infringing, misappropriating or making any unlawful or 
unauthorized use of any Proprietary Asset owned or used by any 
other Person, and none of such products has at any time 
infringed, misappropriated or made any unlawful or unauthorized 
use of, and the Company has not received any notice or other 
communication (in writing or otherwise) of any actual, alleged, 
possible or potential infringement, misappropriation or unlawful 
or unauthorized use of, any Proprietary Asset owned or used by 
any other Person; and (iv) no other Person is infringing, 
misappropriating or making any unlawful or unauthorized use of, 
and no Proprietary Asset owned or used by any other Person 
infringes or conflicts with, any material Company Proprietary 
Asset.

           (d)  The Company Proprietary Assets constitute all the 
Proprietary Assets necessary to enable the Company to conduct its 
business in the manner in which such business has been and is 
being conducted and in the manner in which such business is 
currently proposed to be conducted by the Company.  The Company 
has not (i) licensed any of the material Company Proprietary 
Assets to any Person on an exclusive basis, or (ii) entered into 
any covenant not to compete or Contract limiting its ability to 
exploit fully any material Company Proprietary Assets or to 
transact business in any market or geographical area or with any 
Person.

           (e)  Except as set forth in Part 2.9(e)(i) of the 
Company Disclosure Schedule, the Company has not disclosed or 
delivered to any Person, or permitted the disclosure or delivery 
to any escrow agent or other Person, of the source code, or any 
portion or aspect of the source code, or any proprietary 
information or algorithm contained in any source code, of any 
Company Proprietary Asset.  Part 2.10(a)(ii) of the Company 
Disclosure Schedule identifies each Contract pursuant to which 
the Company has deposited or is required to deposit with an 
escrowholder or any other Person the source code, or any portion 
or aspect of the source code, or any proprietary information or 
algorithm contained in or relating to any source code, of any 
Company Proprietary Asset (the "Escrow Contracts"), and further 
describes whether the execution of this Agreement or the 
consummation of any of the transactions contemplated hereby could 
reasonably be expected to result in the release or disclosure of 

                                   14

the source code, or any portion or aspect of the source code, or 
any proprietary information or algorithm contained in or relating 
to any source code, of any material Company Proprietary Asset.  
To the Company's knowledge, no event has occurred, and no 
circumstance or condition exists, that (with or without notice or 
lapse of time) will, or could reasonably be expected to, result 
in the disclosure or delivery to any Person of the source code, 
or any portion or aspect of the source code, or any proprietary 
information or algorithm contained in any source code, of any 
material Company Proprietary Asset, pursuant to the terms of any 
Escrow Contract.

Material Adverse Effect on the Company.

           (b)  To the Company's knowledge, each Company Contract 
that constitutes a Material Contract is valid and in full force 
and effect, and is enforceable in accordance with its terms,

           (e)  There is no agreement, plan, arrangement or other 
Contract covering any employee or independent contractor or 
former employee or independent contractor of the Company that, 
considered individually or considered collectively with any other 
such Contracts, will, or could reasonably be expected to, give

compensation, stock purchase, stock option, severance pay, 
termination pay, hospitalization, medical, life or other

pension or retirement plan, program or agreement (collectively, 
the "Plans") sponsored, maintained, contributed to or required to 
be contributed to by the Company for the benefit of any current 
or former employee of the Company.

           (b)  Except as set forth in Part 2.16(a) of the 
Company Disclosure Schedule, the Company does not maintain, 
sponsor or contribute to, nor has at any time in the past 
maintained, sponsored or contributed to, any employee pension 
benefit plan (as defined in Section 3(2) of the Employee 
Retirement Income Security Act of 1974, as amended ("ERISA"), 
whether or not excluded from coverage under specific Titles or 
Merger Subtitles of ERISA) for the benefit of employees or former 
employees of the Company (a "Pension Plan").

           (c)  Except as set forth in Part 2.16(a) of the 
Company Disclosure Schedule, the Company does not maintain, 
sponsor or contribute to any: (i) employee welfare benefit plan 
(as defined in Section 3(1) of ERISA, whether or not excluded 
from coverage under specific Titles or Merger Subtitles of ERISA) 
for the benefit of any employees or former employees of the 

                                   18

Company (a "Welfare Plan"), or (ii) self-funded medical, dental 
or other similar Plan.  None of the Plans identified in the 
Company Disclosure Schedule is a multiemployer plan (within the 
meaning of Section 3(37) of ERISA).

           (d)  With respect to each Plan, the Company has made

Plan (including all amendments thereto); (ii) an accurate and 
complete copy of the annual report, if required under ERISA, with 
respect to such Plan for the last two years; (iii) an accurate

accurate and complete copy of the trust or other funding 
agreement (including all amendments thereto) and accurate and

Plan, including service provider agreements, insurance contracts, 
minimum premium contracts, stop-loss agreements, investment 
management agreements, subscription and participation agreements 
and recordkeeping agreements; and (vi) an accurate and complete 
copy of the most recent determination letter received from the 
Internal Revenue Service with respect to such Plan (if such Plan 
is intended to be qualified under Section 401(a) of the Code).

           (e)  The Company is not and has never been required to 
be treated as a single employer with any other Person under 
Section 4001(b)(1) of ERISA or Section 414(b), (c), (m) or (o) of 
the Code.  The Company has never been a member of an "affiliated 
service group" within the meaning of Section 414(m) of the Code. 
The Company has never made a complete or partial withdrawal from 
a multiemployer plan, as such term is defined in Section 3(37) of 
ERISA, resulting in "withdrawal liability," as such term is 
defined in Section 4201 of ERISA (without regard to subsequent 
reduction or waiver of such liability under either Section 4207 
or 4208 of ERISA).

           (f)  The Company does not have any plan or commitment 
to create any Welfare Plan or any additional Pension Plan, or to 
modify or change any existing Pension Plan (other than to comply 
with applicable law) in a manner that would affect any employee 
of the Company.

           (g)  No Plan provides death, medical or health 
benefits (whether or not insured) with respect to any current or 
former employee of the Company after any such employee's 
termination of service (other than (i) benefit coverage mandated 
by applicable law, including coverage provided pursuant to 
Section 4980B of the Code, (ii) deferred compensation benefits 
accrued as liabilities on the Company Unaudited Interim Balance 
Sheet, and (iii) benefits the full cost of which are borne by 
current or former employees of the Company (or the employees' 
beneficiaries)).

           (h)  With respect to any Plan constituting a group 
health plan within the meaning of Section 4980B(g)(2) of the 
Code, the provisions of Section 4980B of the Code ("COBRA") have 
been complied with in all material respects.  Part 2.16(h) of the 
Company Disclosure Schedule describes all obligations of the 
Company as of the date of this Agreement under any of the 
provisions of COBRA.

                                   19

           (i)  Each of the Plans has been operated and 
administered in all material respects in accordance with 
applicable Legal Requirements, including but not limited to ERISA 
and the Code.

           (j)  Each of the Plans intended to be qualified under 
Section 401(a) of the Code has received a favorable determination 
from the Internal Revenue Service, and the Company is not aware 
of any reason why any such determination letter should be 
revoked.

           (k)  Neither the execution, delivery or performance of 
this Agreement, nor the consummation of the Merger or any of the 
other transactions contemplated by this Agreement, will result in 
any payment (including any bonus, golden parachute or severance 
payment) to any current or former employee or director of the 
Company (whether or not under any Plan), or materially increase 
the benefits payable under any Plan, or result in any 
acceleration of the time of payment or vesting of any such 
benefits.

           (l)  Part 2.16(l) of the Company Disclosure Schedule 
contains a list of all salaried employees of the Company as of 
the date of this Agreement, and correctly reflects, in all 
material respects, their salaries, any other compensation payable 
to them (including compensation payable pursuant to bonus, 
deferred compensation or commission arrangements), their dates of 
employment and their positions.  The Company is not a party to 
any collective bargaining contract or other Contract with a labor 
union involving any of its employees.  All of the employees of 
the Company are "at will" employees.

           (m)  Part 2.16(m) of the Company Disclosure Schedule 
identifies each Employee who is not fully available to perform 
work because of disability or other leave and sets forth the 
basis of such leave and the anticipated date of return to full 
service.

            (n)  The Company does not have any knowledge of any 
facts indicating that (i) the consummation of the Merger or any 
of the other transactions contemplated by this Agreement will 
have a Material Adverse Effect on the labor relations of the 
Company, or (ii) any of the employees of the Company intends to 
terminate his or her employment with the Company, except for such 
terminations that either individually or taken together with all 
other such terminations, would not have a Material Adverse Effect 
on the Company.

      2.17  Environmental Matters.  The Company is in compliance 
in all material respects with all applicable Environmental Laws, 
which compliance includes the possession by the Company of all 
permits and other Governmental Authorizations required under 
applicable Environmental Laws, and compliance with the terms and 
conditions thereof.  The Company has not received any notice from 
a Governmental Body, that alleges that the Company is not in 
compliance with any Environmental Law, and, to the knowledge of 
the Company, there are no circumstances that may prevent or 
interfere with the compliance by the Company with any 
Environmental Law in the future.  To the knowledge of the 
Company, no current or prior owner of any property leased or 
controlled by the Company has received any notice from a 
Government Body that alleges that such current or prior owner or 
the Company is not in compliance with any Environmental Law.   To 
the knowledge of the Company, all property that is leased to, 
controlled by or used by the Company, and all surface water, 

                                   20

groundwater and soil associated with or adjacent to such property 
is in clean and healthful condition and is free of any material 
environmental contamination of any nature.  (For purposes of this 
Section 2.17: (i) "Environmental Law" means any federal, state, 
local or foreign Legal Requirement relating to pollution or 
protection of human health or the environment (including ambient 
air, surface water, ground water, land surface or subsurface 
strata), including any law or regulation relating to emissions, 
discharges, releases or threatened releases of Materials of 
Environmental Concern, or otherwise relating to the manufacture, 
processing, distribution, use, treatment, storage, disposal, 
transport or handling of Materials of Environmental Concern; and 
(ii) "Materials of Environmental Concern" include chemicals, 
pollutants, contaminants, wastes, toxic substances, petroleum and 
petroleum products and any other substance that is now or 
hereafter regulated by any Environmental Law or that is otherwise 
a danger to health, reproduction or the environment.)

      2.18  Insurance.  The Company has made available to Parent 
a copy of all material insurance policies relating to the 
business, assets and operations of the Company.  Each of such 
insurance policies is in full force and effect.  Since 
December 31, 1996, the Company has not received any notice or 
other communication regarding any actual or possible (a) 
cancellation or invalidation of any insurance policy, (b) refusal 
of any coverage or rejection of any material claim under any 
insurance policy, or (c) material adjustment in the amount of the 
premiums payable with respect to any insurance policy.  Except as 
set forth in Part 2.18 of the Company Disclosure Schedule, there 
is no pending claim (including any workers' compensation claim) 
under or based upon any insurance policy of the Company.

      2.19  Transactions with Affiliates.  Except as set forth in 
the Company SEC Documents and Part 2.19 of the Company Disclosure 
Schedule, since the date of the Company's last proxy statement 
filed with the SEC, no event has occurred that would be required 
to be reported by the Company pursuant to Item 404 of Regulation 
S-K promulgated by the SEC.  Part 2.19 of the Company Disclosure 
Schedule identifies each person who is an "affiliate" (as that 
term is used in Rule 145 under the Securities Act) of the Company 
as of the date of this Agreement.

      2.20  Legal Proceedings; Orders.

           (a)  There is no pending Legal Proceeding, and (to the 
knowledge of the Company) no Person has threatened to commence 
any Legal Proceeding:  (i) that involves the Company or any of 
the assets owned or used by the Company which alone or in the 
aggregate has had or would have a Material Adverse Effect on the 
Company; or (ii) that challenges, or that may have the effect of 
preventing, delaying, making illegal or otherwise interfering 
with, the Merger or any of the other transactions contemplated by 
this Agreement.  To the knowledge of the Company, no event has 
occurred, and no claim, dispute or other condition or 
circumstance exists, that could reasonably be expected to, give 
rise to or serve as a basis for the commencement of any such 
Legal Proceeding that would have a Material Adverse Effect on the 
Company.  

           (b)  There is no material order, writ, injunction, 
judgment or decree to which the Company, or any of the assets 
owned or used by the Company, is subject.  To the knowledge of 
the Company, no officer or key employee of the Company is subject 
to any order, writ, injunction, judgment or decree that prohibits 

                                   21

such officer or other employee from engaging in or continuing any 
conduct, activity or practice relating to the business of the 
Company.

      2.21  Authority; Binding Nature of Agreement.  The Company 
has the requisite corporate power and authority to enter into and 
to perform its obligations under this Agreement, subject to the 
approval of this Agreement by the Required Company Stockholder 
Vote.  The Board of Directors of the Company (at a meeting duly 
called and held) has (a) unanimously determined that the Merger 
is advisable and fair and in the best interests of the Company 
and its stockholders, (b) unanimously authorized and approved the 
execution, delivery and performance of this Agreement by the 
Company and unanimously approved the Merger, and (c) unanimously 
recommended the approval of this Agreement and the Merger by the 
holders of Company Common Stock and directed that this Agreement 
and the Merger be submitted for consideration by the Company's 
stockholders at the Company Stockholders' Meeting (as defined in 
Section 5.2).  This Agreement constitutes the legal, valid and 
binding obligation of the Company, enforceable against the 
Company in accordance with its terms, subject to (i) laws of 
general application relating to bankruptcy, insolvency and the 
relief of debtors, and (ii) rules of law governing specific 
performance, injunctive relief and other equitable remedies.

      2.22  No Existing Discussions.  During the period between 
August 26, 1997, the date on which the parties entered into a 
non-solicitation agreement, and the date of this Agreement, 
neither the Company nor any Representative of the Company, is or 
was engaged, directly or indirectly, in any discussions or 
negotiations with any other Person relating to any Acquisition 
Proposal.

      2.23  Accounting Matters.  To the knowledge of the Company, 
neither the Company nor any affiliate (as that term is used in 
Rule 145 under the Securities Act) of the Company has taken or 
agreed to take, or plans to take, any action that could prevent 
Parent from accounting for the Merger as a "pooling of 
interests."   Ernst & Young LLP has confirmed orally to the 
Company, Parent, and Price Waterhouse LLP, that, after having 
reviewed the transactions contemplated by this Agreement and 
having conducted a reasonable investigation of the Company, Ernst 
& Young LLP is not aware of any fact concerning the Company that 
could preclude Parent from accounting for the Merger as a 
"pooling of interests."
 
      2.24  Vote Required.  The affirmative vote of the holders 
of a majority of the shares of Company Common Stock outstanding 
on the record date for the Company Stockholders' Meeting (the 
"Required Company Stockholder Vote") is the only vote of the 
holders of any class or series of the Company's capital stock 
necessary to approve this Agreement, the Merger and the other 
transactions contemplated by this Agreement.

      2.25  Non-Contravention; Consents.  Neither (1) the 
execution, delivery or performance of this Agreement or any of 
the other agreements referred to in this Agreement, nor (2) the 
consummation of the Merger or any of the other transactions 
contemplated by this Agreement, will directly or indirectly (with 
or without notice or lapse of time):

           (a)  contravene, conflict with or result in a 
violation of (i) any of the provisions of the certificate of 
incorporation, bylaws or other charter or organizational 

                                   22

documents of the Company, as amended, or (ii) any resolution 
adopted by the stockholders, the Board of Directors or any 
committee of the Board of Directors of the Company;

           (b)  contravene, conflict with or result in a 
violation of, or give any Governmental Body or other Person the 
right to challenge the Merger or any of the other transactions 
contemplated by this Agreement or to exercise any remedy or 
obtain any relief under, any Legal Requirement or any order, 
writ, injunction, judgment or decree to which the Company, or any 
of the assets owned or used by the Company, is subject;

           (c)  contravene, conflict with or result in a 
violation of any of the terms or requirements of, or give any

by the Company or that otherwise relates to the business of the 
Company or to any of the assets owned or used by the Company;

           (d)  contravene, conflict with or result in a 
violation or breach of, or result in a default under (or an event 
which with notice or lapse of time or both would become a 
default), any provision of any Material Contract, or give any 
Person the right to (i) declare a default or exercise any remedy 
under any such Material Contract, (ii) a rebate, chargeback, 
penalty or change in delivery schedule under any such Material 
Contract, (iii) accelerate the maturity or performance of any 
such Material Contract, or (iv) cancel, terminate or modify any 
term of such Material Contract;

           (e)  result in the imposition or creation of any 
Encumbrance upon or with respect to any asset owned or used by 
the Company (except for liens that will not, in any case or in 
the aggregate, have a Material Adverse Effect on the Company); or

           (f)  result in, or increase the likelihood of, the 
disclosure or delivery to any escrowholder or other Person of the 
source code, or any portion or aspect of the source code, or any 
proprietary information or algorithm contained in or relating to 
any source code, of any material Company Proprietary Asset, or 
the transfer of any material asset of the Company to any Person 
pursuant to any Escrow Contract.

Except as may be required by the Exchange Act, the DGCL, and the 
NASD Bylaws (as they relate to the Form S-4 Registration 
Statement and the Joint Proxy Statement) the Company has not 
been, is not or will not be required to make any filing with or 
give any notice to, or to obtain any Consent from, any Person in 
connection with (i) the execution, delivery or performance of 
this Agreement or any of the other agreements referred to in this 
Agreement, or (ii) the consummation of the Merger or any of the 
other transactions contemplated by this Agreement.

has received the written opinion of CIBC Wood Gundy, financial 
advisor to the Company, dated the date of this Agreement, to the 
effect that the consideration to be received by the stockholders 
of the Company in the Merger is fair to the stockholders of the 
Company from a financial point of view.  The Company has 
furnished an accurate and complete copy of said written opinion 
to Parent.

                                   23

fees and expenses of all accountants, brokers, financial 
advisors, legal counsel and other Persons retained by the Company 
in connection with the negotiation and effectuation of this 
Agreement and the transactions contemplated hereby incurred or to

aggregate.  The Company has furnished to Parent accurate and 
complete copies of all agreements under which any such fees, 
commissions or other amounts have been paid or may become payable 
and all indemnification and other agreements related to the

unlawful payment.

      3.14  Governmental Authorizations.  Parent holds all 
material Governmental Authorizations necessary to enable Parent

           (d)  No claim or Legal Proceeding is pending or, to

the Code.  Parent has never been a member of an "affiliated 
service group" within the meaning of Section 414(m) of the Code. 
 Parent has never made a complete or partial withdrawal from a 
multiemployer plan, as such term is defined in Section 3(37) of 
ERISA, resulting in "withdrawal liability," as such term is

or 4208 of ERISA).

           (b)  Each of the Plans of Parent has been operated and 
administered in all material respects in accordance with 
applicable Legal Requirements, including but not limited to ERISA

           (d)  Parent is in compliance in all material respects 
with all applicable Legal Requirements and Contracts relating to 
employment, employment practices, wages, bonuses and terms and 
conditions of employment, including employee compensation 
matters.

           (e)  Parent does not have any knowledge of any facts 
indicating that the consummation of the Merger or any of the 
other transactions contemplated by this Agreement will have a 
Material Adverse Effect on the labor relations of Parent.

      3.17  Environmental Matters.  Parent is in compliance in 
all material respects with all applicable Environmental Laws, 
which compliance includes the possession by Parent of all permits 
and other Governmental Authorizations required under applicable 
Environmental Laws, and compliance with the terms and conditions 
thereof.  Parent has not received any notice from a Governmental 
Body that alleges that Parent is not in compliance with any 
Environmental Law, and, to the knowledge of Parent, there are no 
circumstances that may prevent or interfere with the compliance 
by Parent with any Environmental Law in the future.  To the 
knowledge of Parent, no current or prior owner of any property 
leased or controlled by Parent has received any notice from a 
Government Body that alleges that such current or prior owner or 
Parent is not in compliance with any Environmental Law.   To the 
knowledge of Parent, all property that is leased to, controlled 
by or used by Parent, and all surface water, groundwater and soil 
associated with or adjacent to such property is in clean and 
healthful condition and is free of any material environmental 
contamination of any nature.  (For purposes of this Section 3.17: 
(i) "Environmental Law" means any federal, state, local or 
foreign Legal Requirement relating to pollution or protection of 
human health or the environment (including ambient air, surface 
water, ground water, land surface or subsurface strata), 

                                   33

including any law or regulation relating to emissions, 
discharges, releases or threatened releases of Materials of 
Environmental Concern, or otherwise relating to the manufacture, 
processing, distribution, use, treatment, storage, disposal, 
transport or handling of Materials of Environmental Concern; and 
(ii) "Materials of Environmental Concern" include chemicals, 
pollutants, contaminants, wastes, toxic substances, petroleum and 
petroleum products and any other substance that is now or 
hereafter regulated by any Environmental Law or that is otherwise 
a danger to health, reproduction or the environment.)

      3.18  Insurance.  Since December 31, 1996, Parent has not 
received any notice or other communication regarding any actual 
or possible (a) cancellation or invalidation of any insurance 
policy, (b) refusal of any coverage or rejection of any material 
claim under any insurance policy, or (c) material adjustment in 
the amount of the premiums payable with respect to any insurance 
policy.  

      3.19  Transactions with Affiliates.  Except as set forth in 
the Parent SEC Reports, since the date of Parent's last proxy 
statement filed with the SEC, no event has occurred that would be 
required to be reported by the Company pursuant to Item 404 of 
Regulation S-K promulgated by the SEC.  Part 3.19 of the Parent 
Disclosure Schedule identifies each person who is an "affiliate" 
(as that term is used in Rule 145 under the Securities Act) of 
Parent as of the date of this Agreement.

      3.20  Legal Proceedings; Orders.  

           (a)  There is no pending Legal Proceeding, and (to the 
knowledge of Parent) no Person has threatened to commence any 
Legal Proceeding:  (i) that involves Parent or any of the assets 
owned or used by Parent which, alone or in the aggregate, has had 
or would have a Material Adverse Effect on Parent; or (ii) that 
challenges, or that may have the effect of preventing, delaying, 
making illegal or otherwise interfering with, the Merger or any 
of the other transactions contemplated by this Agreement.  To the 
knowledge of Parent, no event has occurred, and no claim, dispute 
or other condition or circumstance exists, that could reasonably 
be expected to, give rise to or serve as a basis for the 
commencement of any such Legal Proceeding that would have a 
Material Adverse Effect on Parent.  

           (b)  There is no material order, writ, injunction, 
judgment or decree to which Parent, or any of the assets owned or 
used by Parent, is subject.  To the knowledge of Parent, no 
officer or key employee of Parent is subject to any order, writ, 
injunction, judgment or decree that prohibits such officer or 
other employee from engaging in or continuing any conduct, 
activity or practice relating to the business of Parent.

      3.21  Authority; Binding Nature of Agreement.  Parent and 
Merger Sub have the requisite corporate power and authority to 
enter into and to perform their obligations under this Agreement, 
subject to the approval of the issuance of Parent Common Stock in 
the Merger by the Required Parent Stockholder Vote.  The Board of 
Directors of Parent (at a meeting duly called and held) has 
(a) unanimously determined that the issuance of Parent Common 
Stock in the Merger is advisable and fair and in the best 
interests of Parent and its stockholders, (b) 

                                   34

unanimously authorized and approved the execution, delivery and 
performance of this Agreement by Parent and unanimously approved 
the issuance of Parent Common Stock in connection with the Merger 
and (c) unanimously recommended the approval of the issuance of 
Parent Common Stock in connection with the Merger by Parent's 
stockholders at the Parent Stockholders' Meeting (as defined in 
Section 5.3).  This Agreement constitutes the legal, valid and 
binding obligation of Parent and Merger Sub, enforceable against 
them in accordance with its terms, subject to (a) laws of general 
application relating to bankruptcy, insolvency and the relief of 
debtors, and (b) rules of law governing specific performance, 
injunctive relief and other equitable remedies.

      3.22  Vote Required.  The only vote of Parent's 
stockholders required to approve the issuance of Parent Common 
Stock in the Merger is the vote prescribed by the NASD Rules (the 
"Required Parent Stockholder Vote").

      3.23  Non-Contravention; Consents.  Neither the execution 
and delivery of this Agreement by Parent and Merger Sub nor the 
consummation by Parent and Merger Sub of the Merger will (a) 
conflict with or result in any breach of any provision of the 
certificate of incorporation or bylaws of Parent or the 
certificate of incorporation or bylaws of Merger Sub, (b) result 
in a default by Parent or Merger Sub under any Parent Material 
Contract to which Parent or Merger Sub is a party, except for any 
default which has not had and will not have a Material Adverse 
Effect on Parent, or (c) result in a violation by Parent or 
Merger Sub of any order, writ, injunction, judgment or decree to 
which Parent or Merger Sub is subject, except for any violation 
which has not had and will not have a Material Adverse Effect on 
Parent.  

      3.24  No Existing Discussions.	During the period between 
August 26, 1997, the date on which the parties entered into a 
non-solicitation agreement, and the date of this Agreement, 
neither Parent nor any Representative of Parent, is or was 
engaged, directly or indirectly, in any discussions or 
negotiations with any other Person relating to any Acquisition 
Proposal with respect to Parent.

      3.25  Accounting Matters.  To the knowledge of Parent, 
neither Parent nor any affiliate (as that term is used in Rule 
145 under the Securities Act) of Parent has taken or agreed to 
take, or plans to take, any action that could prevent Parent from 
accounting for the Merger as a "pooling of interests."  Price 
Waterhouse LLP has confirmed orally to the Company, Parent, and 
Ernst & Young LLP, that, after having reviewed the transactions 
contemplated by this Agreement and having conducted a reasonable 
investigation of Parent, Price Waterhouse LLP is not aware of any 
fact concerning Parent that could preclude Parent from accounting 
for the Merger as a "pooling of interests."

      3.26  Financial Advisor.  Except for Hambrecht & Quist LLC, 
no broker, finder or investment banker is entitled to any 
brokerage, finder's or other fee or commission in connection with 
the Merger or the transactions contemplated by this Agreement 
based upon arrangements made by or on behalf of Parent. 


                                   35

      3.27  Fairness Opinion.  Parent's Board of Directors has 
received the written opinion of Hambrecht & Quist LLC, financial 
advisor to Parent, dated the date of this Agreement, to the 
effect that the Exchange Ratio is fair to Parent and its 
stockholders from a financial point of view.

      3.28  Valid Issuance.  The Parent Common Stock to be issued 
in the Merger will, when issued in accordance with the provisions 
of this Agreement, be validly issued, fully paid and 
nonassessable.

all applicable Legal Requirements to call, give notice of, 
convene and hold a meeting of the holders of Company Common Stock 
to consider, act upon and vote upon the approval of this 
Agreement and of the Merger (the "Company Stockholders' 
Meeting").  The Company Stockholders' Meeting will be held as 
promptly as practicable and in any event within 45 days after the 
Form S-4 Registration Statement is declared effective under the 
Securities Act.  The Company shall ensure that the Company 

                                   42

Stockholders' Meeting is called, noticed, convened, held and 
conducted, and that all proxies solicited in connection with the

all applicable Legal Requirements.  

           (b)  Subject to Section 5.2(c):  (i) the Board of 
Directors of the Company shall unanimously recommend that the 
Company's stockholders vote in favor of and approve and adopt 
this Agreement and approve the Merger at the Company

include a statement to the effect that the Board of Directors of 
the Company has unanimously recommended that the Company's

Meeting; and (iii) neither the Board of Directors of the Company 
nor any committee thereof shall withdraw, amend or modify, or 
propose or resolve to withdraw, amend or modify, in a manner 
adverse to Parent, the unanimous recommendation of the Board of 
Directors of the Company that the Company's stockholders vote in 
favor of and approve and adopt this Agreement and approve the 
Merger.  For purposes of this Agreement, said recommendation of 
the Board of Directors of the Company shall be deemed to have 
been modified in a manner adverse to Parent if said 
recommendation shall no longer be unanimous.

           (c)  Notwithstanding any other provision in this 
Agreement, prior to the approval of this Agreement by the

Company may, in light of the Superior Offer, to the extent it 
determines in good faith, after consultation with outside legal 
counsel, that it is required to do so in order to comply with its 
fiduciary duties to the Company's stockholders under applicable 
law, withdraw or modify its approval or recommendation of this 
Agreement and the Merger or approve or recommend such Superior 
Offer; provided that, in so withdrawing or modifying its approval 
or recommendation of this Agreement and the Merger and/or 
recommending or approving a Superior Offer, neither the Company 
nor its Representatives shall have breached Section 4.4, 
provided, further, that the Company may refrain from soliciting 
proxies from its stockholders with respect to this Agreement and

 To the extent that there is no temporary restraining order, 
preliminary or permanent injunction or other final and 
nonappealable order, decree or ruling issued by any court of 
competent jurisdiction which remains in effect and which has the 
effect of permanently restraining, enjoining or otherwise 
prohibiting the Merger, the Company shall remain obligated and 
nothing shall limit the Company's obligation under Section 5.2(a) 
to call, give notice of, include Parent's proxy solicitation 
materials in the notice materials mailed by the Company to the 
Company's stockholders, convene and hold the Company 
Stockholders' Meeting and to cause the Company's stockholders to 
take a final vote on this Agreement and the Merger (regardless of 
whether the unanimous recommendation of the Board of Directors of 
the Company shall have been withdrawn, amended or modified).

applicable Legal Requirements to call, give notice of, convene

Merger (the "Parent Stockholders' Meeting").  The Parent 
Stockholders' Meeting will be held as promptly as practicable and 
in any event within 45 days after the Form S-4 Registration 
Statement is declared effective under the Securities Act; 
provided, however, that notwithstanding the foregoing, nothing in 
this Section 5.3 shall obligate Parent to call, give notice of, 
convene or hold a Parent Stockholders' Meeting (i) if the holders 
of the Company Common Stock do not approve and adopt this 
Agreement and approve the Merger or (ii) if, prior to the time 
the Parent Stockholders' Meeting is scheduled to be held, there 
is a Material Adverse Effect on the Company that arose from 
(A) the Company's breach of or failure to perform its covenants 
as set forth in Sections 4 and 5 hereof, or (B) the Company's 
breach of or inaccuracy of any of its representations and 
warranties as set forth in Section 2 that resulted from facts, 
circumstances, events or conditions which existed at any time 
prior to and through the date of this Agreement.

           (b)  (i) The Board of Directors of Parent shall 
unanimously recommend that Parent's stockholders vote in favor of 
the issuance of Parent Common Stock in the Merger; (ii) the Joint 
Proxy Statement shall include a statement to the effect that the

Parent's stockholders vote in favor of the issuance of Parent 
Common Stock in the Merger; and (iii) neither the Board of 
Directors of Parent nor any committee thereof shall withdraw, 
amend or modify, or propose or resolve to withdraw, amend or 
modify, in a manner adverse to the Company, the unanimous 
recommendation of the Board of Directors of Parent that Parent's

      5.4  Regulatory Approvals.  The Company and Parent shall 
use all reasonable efforts to file, as soon as practicable after 
the date of this Agreement, all notices, reports and other 
documents required to be filed with any Governmental Body with

      5.5  Stock Options, Warrants, and Employee Stock Purchase 
Plans.  

           (a)  Subject to Section 5.5(b), at the Effective Time 
by virtue of the Merger and without the need for any further 
corporate action, all rights with respect to Company Common Stock 
under each Company Option then outstanding shall be converted 
into and become rights with respect to Parent Common Stock, and 
Parent shall assume each such Company Option in accordance with 
the terms of the stock option plan (as in effect as of the date 
of this Agreement) under which it was issued and the stock option 
agreement by which it is evidenced.  From and after the Effective 
Time, (i) each Company Option assumed by Parent may be exercised 
solely for shares of Parent Common Stock, (ii) the number of 
shares of Parent Common Stock subject to each such Company Option 
shall be equal to the number of shares of Company Common Stock 
subject to such Company Option immediately prior to the Effective 
Time multiplied by the Exchange Ratio, rounding down to the 
nearest whole share (with cash, less the applicable exercise 
price, being payable for any fraction of a share), (iii) the per 
share exercise price under each such Company Option shall be 
adjusted by dividing the per share exercise price under such 
Company Option by the Exchange Ratio and rounding up to the 
nearest cent and (iv) any restriction on the exercise of any such 
Company Option shall continue in full force and effect and the 
term, exercisability, vesting schedule and other provisions of 
such Company Option shall otherwise remain unchanged; provided, 
however, that each Company Option assumed by Parent in accordance 
with this Section 5.5(a) shall, in accordance with its terms, be 
subject to further adjustment as appropriate to reflect any stock 
split, stock dividend, reverse stock split, reclassification, 
recapitalization or other similar transaction subsequent to the 
Effective Time.  Parent shall file with the SEC, no later than 5 
days after the Effective Time, a registration statement on Form 
S-8 relating to the shares of Parent Common Stock issuable with 
respect to the Company Options assumed by Parent in accordance 
with this Section 5.5(a).  The adjustments provided herein with 
respect to any Company Option that are "incentive stock options" 
as defined in Section 422 of the Code shall be and are intended 
to be effected in a manner which is consistent with Section 
424(a) of the Code.  

           (b)  Notwithstanding anything to the contrary 
contained in this Section 5.5, in lieu of assuming outstanding 
Company Options in accordance with Section 5.5(a), Parent may, at 
its election, cause such outstanding Company Options to be 
replaced by issuing reasonably equivalent replacement stock 
options in substitution therefor.  

           (c)  The Company shall take all action that may be 
necessary (under the plans pursuant to which Company Options are 
outstanding and otherwise) to effectuate the provisions of this 
Section 5.5 and to ensure that, from and after the Effective 
Time, holders of Company Options have no rights with respect 
thereto other than those specifically provided in this Section 
5.5.  As soon as practicable after the Effective Time, Parent 
shall deliver to the participants in the Company Stock Plans 
appropriate notice setting forth such participants' rights 
pursuant thereto and the assumption of such Company Stock Plans 
by Parent as described in Section 5.5(a).

           (d)  At the Effective Time, all rights with respect to 
the Company Warrants that are then outstanding shall be converted 
into and become rights with respect to Parent Common Stock, and 
Parent shall assume each Company Warrant in accordance with the 
terms (as in effect as of the date hereof) of such Company 
Warrants.  From and after the Effective Time, (i) each Company 

                                  45

Warrant assumed by Parent may be exercised solely for shares of 
Parent Common Stock, (ii) the number of shares of Parent Common 
Stock subject to each such Company Warrant shall be equal to the 
number of shares of Company Common Stock subject to such Company 
Warrant immediately prior to the Effective Time multiplied by the 
Exchange Ratio, rounding down to the nearest whole share (with 
cash, less the applicable exercise price, being payable for any 
fraction of a share), (iii) the per share exercise price under 
each such Company Warrant shall be adjusted by dividing the per 
share exercise price under such Company Warrant by the Exchange 
Ratio and rounding up to the nearest cent and (iv) any 
restriction on the exercise of any such Company Warrant shall 
continue in full force and effect and the term, exercisability, 
vesting schedule and other provisions of such Company Warrant 
shall otherwise remain unchanged; provided, however, that each 
Company Warrant assumed by Parent in accordance with this Section 
5.5(d) shall, in accordance with its terms, be subject to further 
adjustment as appropriate to reflect any stock split, stock 
dividend, reverse stock split, reclassification, recapitalization 
or other similar transaction subsequent to the Effective Time.  
The Company shall take all action that may be necessary (under 
the Company Warrants and otherwise) to effectuate the provisions 
of this Section 5.5(d) and to ensure that, from and after the 
Effective Time, holders of Company Warrants have no rights with 
respect thereto other than those specifically provided herein.  
As soon as practicable after the Effective Time, Parent shall 
deliver to the Company Warrant holders appropriate notice setting 
forth such holders' rights pursuant thereto and the assumption of 
such Company Warrants by Parent as described in this Section 
5.5(d).

           (e)  The Company shall terminate the Company's 1996 
Employee Stock Purchase Plan ("ESPP") by having its Board of 
Directors amend the ESPP as necessary to provide that:  (i) any 
shares of Company Common Stock shall be purchased under the ESPP 
on a new "Exercise Date" (as such term is defined in the ESPP) 
set by the Board of Directors of the Company, which new Exercise 
Date shall be on the last trading day immediately prior to the 
Effective Time, or such earlier time as the Board of Directors of 
the Company shall specify and (ii) immediately following such 
purchase of shares of Company Common Stock on the new Exercise 
Date, the ESPP shall terminate.

           (f)  Parent shall assume all Stock Purchase Agreements 
and the Company shall assign its repurchase rights under such 
Stock Purchase Agreements to Parent pursuant to Section 10 of the 
Stock Purchase Agreements.  The Stock Purchase Agreements so 
assumed by Parent under this Agreement will continue to have, and 
be subject to, the same terms and conditions set forth in the 
applicable Stock Purchase Agreement by which it is evidenced 
(including, without limitation, any repurchase rights) 
immediately prior to the Effective Time, except that (i) the 
Stock Purchase Agreement will be for that number of whole shares 
(and no fractional shares) of Parent Common Stock equal to the 
product of the number of shares of Company Common Stock that have 
not vested immediately prior to the Effective Time multiplied by 
the Exchange Ratio, rounded down to the nearest whole number of 
shares of Parent Common Stock and (ii) the per share repurchase 
price for the unvested shares of Parent Common Stock subject to 
the repurchase right will be equal to the quotient determined by 
dividing the purchase price per share of Company Common Stock at 
which such Company Common Stock was purchased under the Stock 
Purchase Agreement by the Exchange Ratio, rounded up to the 
nearest whole cent.

                                   55

further that Parent may not terminate this Agreement pursuant to

become materially inaccurate, or if any of Parent's covenants 
contained in this Agreement shall have been breached in any 
material respect, in either case such that the conditions set 
forth in Section 7.1, 7.2 or 7.6 would not be satisfied as of the 
time such representation or warranty shall have become inaccurate 
or as of the time of such breach; provided, however, that if an 
inaccuracy in Parent's representations and warranties or a breach 
of a covenant by Parent is curable by Parent and Parent is 
continuing to exercise all reasonable efforts to cure such 
inaccuracy or breach during the 45-day period commencing upon 
delivery by the Company of a written notice to Parent describing 
such inaccuracy or breach, then the Company may not terminate 
this Agreement under this Section 8.1(h) on account of such 
inaccuracy or breach until the end of such cure period (if such 
inaccuracy or breach then remains uncured), and provided further 
that the Company may not terminate this Agreement pursuant to 
this Section 8.1(h) if it shall have materially breached this 
Agreement (it being understood that (i) the cure period described 
in this Section 8.1(h) shall in no event extend beyond January 
31, 1998 and (ii) that any such cure shall not individually or in 
the aggregate have or reasonably be expected to have a Material 
Adverse Effect on Parent); or

Voting Agreement in favor of Parent, in the form of Exhibit G, 
shall have breached, withdrawn, amended or modified in a manner 
adverse to Parent, such Voting Agreement, (ii) if, prior to the 
Effective Time, any Person who has signed a Voting Agreement 
challenges the validity of such Voting Agreement, (iii) if any

Agreement votes in favor of an Acquisition Proposal.

      8.2  Effect of Termination.  In the event of the 
termination of this Agreement as provided in Section 8.1, this 
Agreement shall be of no further force or effect and shall 
relieve Parent, Merger Sub and the Company of any liability or 
obligation under this Agreement; provided, however, that the 
liabilities and obligations under (i) Sections 5.9, 8.2, 8.3 and 
9 shall survive the termination of this Agreement and shall 
remain in full force and effect, and (ii) the termination of this 
Agreement shall not relieve any party from any liability for any

           (a)  Except as set forth in this Section 8.3, all fees 
and expenses incurred in connection with this Agreement and the

Expenses"), the adjustment set forth in Section 1.5(e) shall be 
made.

           (b)  If this Agreement is terminated:

                (i)  pursuant to Section 8.1(d) by Parent or the 
Company (and if by Parent, only if at the time the Company 
Stockholders' Meeting was held, there existed a publicly 
announced and pending Acquisition Proposal), 

                (ii)  pursuant to Section 8.1(f) by Parent or the 
Company (and if by Parent, unless the occurrence of a Company 
Triggering Event is attributable to Parent's failure to meet the 
condition set forth in Section 7.6 (but only if such failure to

Parent's breach of or failure to perform its covenants as set 
forth in Sections 4 and 5, or (B) Parent's breach of or 
inaccuracy of any of its representations and warranties as set 
forth in Section 3 that resulted from facts, circumstances,

covenants as set forth in Sections 4 and 5, or (B) Parent's 
breach of or inaccuracy of any of its representations and 
warranties as set forth in Section 3 that resulted from facts,

6.5(c), 6.5(d), (but only if such condition was not met due to a 
change in the Company's situation between the date of this

such Material Adverse Effect arose from (A) the Company's breach 
of or failure to perform its covenants as set forth in Sections 4

representations and warranties as set forth in Section 2 that 
resulted from facts, circumstances, events or conditions which 
existed at any time prior to and through the date of this 
Agreement) have not been met), 

                (ii)  pursuant to Section 8.1(e) by either Parent 
or the Company (and if by the Company, unless the condition set 
forth in Section 6.6 has not been met by the Company at the time 
the Parent Stockholders' Meeting, during which the Required 
Parent Stockholder Vote was not obtained, is held (but only if 
such failure to meet the condition set forth in Section 6.6 arose 
from (A) the Company's breach of or failure to perform its 
covenants as set forth in Sections 4 and 5, or (B) the Company's 
breach of or inaccuracy of any of its representations and 
warranties as set forth in Section 2 that resulted from facts, 
circumstances, events or conditions which existed at any time 
prior to and through the date of this Agreement)), 

                (iii)  pursuant to Section 8.1(g) by Parent

result of (A) the Company's breach of or failure to perform its 
covenants as set forth in Sections 4 and 5, or (B) the Company's 
breach of or inaccuracy of any of its representations and 
warranties as set forth in Section 2 that resulted from facts,

Company; and whether before or after approval of the issuance of 
Parent Common Stock in the Merger by Parent's stockholders) 
provided, however, that (i) after any such approval of this 
Agreement and the Merger by the Company's stockholders, no 
amendment shall be made which by law requires further approval of 
the stockholders of the Company without the further approval of 
such stockholders, and (ii) after any such approval of the 
issuance of Parent Common Stock in the Merger, no amendment shall 
be made which by law or NASD regulation requires further approval

instrument in writing signed on behalf of each of the parties 
hereto.

any power, right, privilege or remedy under this Agreement, and

privilege or remedy under this Agreement, shall operate as a 
waiver of such power, right, privilege or remedy; and no single 
or partial exercise of any such power, right, privilege or remedy 
shall preclude any other or further exercise thereof or of any 
other power, right, privilege or remedy.  

           (b)  No party shall be deemed to have waived any claim 
arising out of this Agreement, or any power, right, privilege or 
remedy under this Agreement, unless the waiver of such claim,

respect to the subject matter hereof and thereof.  

           (b)  This Agreement may be executed in several 
counterparts, each of which shall be deemed an original and all

as applied to contracts entered into and to be performed entirely 
within Delaware.  

           (c)  Each of the parties hereto (i) consents to submit

States located in the State of Delaware or of any Delaware state 

                                   59

court in the event any dispute arises out of this Agreement or 
the transactions contemplated by this Agreement, (ii) agrees that 
it will not attempt to deny or defeat such personal jurisdiction 
by motion or other request for leave from any such court and

Agreement or the transactions contemplated by this Agreement in 
any court other than a court of the United States located in the 
State of Delaware or a Delaware state court.

action or suit.

      9.6  Assignability.  This Agreement shall be binding upon, 
and shall be enforceable by and inure solely to the benefit of, 
the parties hereto and their respective successors and assigns; 
provided, however, that neither this Agreement nor any of the 
Company's rights hereunder may be assigned, by operation of law 
or otherwise, in whole or in part by any of the parties without 
the prior written consent of the other party, and any attempted 
assignment of this Agreement or any of such rights by a party 
without such consent shall be void and of no effect.  Except as 
set forth in Section 5.6 with respect to the current directors 
and officers of the Company, nothing in this Agreement, express 
or implied, is intended to or shall confer upon any Person any 
right, benefit or remedy of any nature whatsoever under or by

                 FORM OF AFFILIATE AGREEMENT


      This Affiliate Agreement (this "Agreement") is being 
executed and delivered as of              , 1997 by             
("Affiliate") in favor of and for the benefit of Lumisys 
Incorporated, a Delaware corporation ("Parent").

                           Recitals

      A.  Affiliate is a stockholder [and an officer and 
director] of CompuRAD, Inc., a Delaware corporation (the 
"Company").

      B.  Parent, the Company and SAC Acquisition Corporation, a 
Delaware corporation and a wholly owned subsidiary of Parent 
("Merger Sub"), have entered into an Agreement and Plan of Merger 
and Reorganization dated as of _________ __, 1997 (the 
"Reorganization Agreement"), providing for the merger of Merger 
Sub with and into the Company (the "Merger").  The Reorganization 
Agreement contemplates that, upon consummation of the Merger, (i)

exchange for their shares of the common stock, par value $.01 per

Company will become a wholly owned subsidiary of Parent.  It is 
accordingly contemplated that Affiliate will receive shares of 
Parent Common Stock in the Merger.

      C.  Affiliate may be deemed to be an "affiliate" of the 
Company for purposes of: (i) the restrictions on resale imposed 
by the Securities Act of 1933, as amended (the "Act"); and (ii) 
determining Parent's eligibility to account for the Merger as a 
"pooling of interests" under applicable "pooling of interests" 
accounting requirements (including Accounting Principles Board 
Opinion No. 16 and Accounting Series Releases 130 and 135, as 
amended, of the Securities and Exchange Commission (the "SEC")).

                         Agreement

      18.  Representations and Warranties.  Affiliate represents 
and warrants to Parent as follows: 

           1.  Restrictions as Affiliate.

                (a)  Affiliate is the holder and beneficial owner 
of               (      ) shares of Company Common Stock (the 
"Company Shares"), and Affiliate has good and valid title to the

interests, adverse claims, equities, options, proxies, charges, 
encumbrances or restrictions of any nature. 


                                   A-1

                (b) Affiliate has carefully read this Agreement, 
and has discussed with counsel to the extent Affiliate felt 
necessary the limitations imposed on Affiliate's ability to sell, 
transfer or otherwise dispose of the Company Shares and the 
shares of Parent Common Stock that Affiliate is to receive in the 
Merger (the "Parent Shares").  Affiliate fully understands the 
limitations this Agreement places upon Affiliate's ability to 
sell, transfer or otherwise dispose of the Company Shares and the 
Parent Shares.

                (c)  Affiliate understands that the 
representations, warranties and covenants set forth in this 
Agreement will be relied upon by Parent and its counsel and 
accountants for purposes of determining Parent's eligibility to 
account for the Merger as a "pooling of interests," for purposes 
of determining whether Parent should proceed with the Merger and 
for various other purposes.

           2.  Continuity of Interest.

contemplation of the Merger.

                (c)  Affiliate has no plan or intention to engage

reduction in any way of Affiliate's risk of ownership (by short 
sale or otherwise), or other disposition, directly or indirectly 
(such actions being collectively referred to herein as a "Sale") 
of more than fifty percent (50%) of the shares of Parent Common 
Stock to be received by Affiliate in the Merger.  (For purposes 
of the preceding sentence, shares of Company Common Stock (or the 
portion thereof) (i) with respect to which Affiliate will receive 
consideration in the Merger other than shares of Parent Common 
Stock (including cash to be received in lieu of fractional shares 
of Parent Common Stock) and/or (ii) with respect to which a Sale 
(A) occurred in contemplation of the Merger or (B) will occur 
prior to the Merger, shall be considered shares of Company Common 
Stock exchanged for shares of Parent Common Stock in the Merger 
and then disposed of pursuant to a plan).

                (d)  Affiliate has no plan or intention to 
exercise dissenters' rights in connection with the Merger.

in, any plan or intention on the part of the stockholders of the 
Company to engage in a Sale or Sales of more than fifty percent

Merger.  (For purposes of the preceding sentence, shares of 
Company Common Stock (or the portion thereof) (i) with respect to 
which a stockholder of the Company receives consideration in the 
Merger other than shares of Parent Common Stock (including, 
without limitation, cash received pursuant to the exercise of 
dissenters' rights or in lieu of a fractional share of Parent 
Common Stock) or (ii) with respect to which a Sale occurs prior 
to and in contemplation of the Merger, shall be considered shares 
of outstanding Company Common Stock exchanged for shares of 
Parent Common Stock in the Merger and then disposed of pursuant 
to a plan).

                (f)  Except to the extent written notification to 
the contrary is received by Parent and the Company from Affiliate 
prior to the consummation of the Merger, the representations, 
warranties and certifications contained herein shall be accurate 
at all times from the date hereof through the date on which the 
Merger is consummated.
	
                (g)  Affiliate has consulted with such legal 
counsel and financial advisors as he has deemed appropriate in 
connection with the execution of this Agreement.

                (h)  Affiliate understands that Parent, Merger 
Sub, the Company, and the Company's stockholders, as well as 
legal counsel to Parent, Merger Sub and the Company (in 
connection with rendering their opinions that the Merger will be 
a "reorganization" within the meaning of Section 368(a) of the 
Internal Revenue Code of 1986, as amended) will be relying on (a) 
the truth and accuracy of the representations, warranties and 
certifications contained herein and (b) Affiliate's performance 
of the obligations set forth herein.


      19.  Prohibitions Against Transfer.

           1.  Affiliate agrees that during the period from the 
date on which the Merger is consummated through the date on which 
financial results covering at least thirty (30) days of post-
Merger combined operations of Parent and the Company have been 
published by Parent (within the meaning of the applicable 
"pooling of interests" accounting requirements), Affiliate agrees 
that (i) he shall not sell, transfer or otherwise dispose of, or 
reduce his interest in or risk relating to, any shares of Parent 
Common Stock (including the Parent Shares), and (ii) he shall 
ensure that none of his children sells, transfers or otherwise 
disposes of, or reduces his interest in or risk relating to, any 
shares of Parent Common Stock received in the Merger.

           2.  Without limiting the generality of Section 2(a) of 
this Agreement, Affiliate shall not effect any sale, transfer or 
other disposition of any of the Parent Shares, and Affiliate 
shall ensure that none of his children effects any sale, transfer 
or other disposition of any shares of Parent Common Stock 
received in the Merger; unless:

                (a)  such sale, transfer or other disposition has 
been registered under the Act;

                                   A-3


                (b)  such sale, transfer or other disposition is 
made in conformity with the requirements of Rule 144 under the 
Act, as evidenced by a broker's letter and a representation 
letter executed by Affiliate (satisfactory in form and content to 
Parent) stating that such requirements have been met;

                (c)  counsel reasonably satisfactory to Parent 
shall have advised Parent in a written opinion letter 
(satisfactory in form and content to Parent), upon which Parent 
may rely, that such sale, transfer or other disposition will be 
exempt from registration under the Act; or

                (d)  an authorized representative of the SEC 
shall have rendered written advice to Affiliate to the effect 
that the SEC would take no action, or that the staff of the SEC 
would not recommend that the SEC take action, with respect to 
such sale, transfer or other disposition, and a copy of such 
written advice and all other related communications with the SEC 
shall have been delivered to Parent.

      20.  Stop Transfer Instructions; Legend.

           Affiliate understands that the Parent Shares will be 
characterized as "restricted securities" for purposes of Rule 144 
under the Act, and that therefore any sale, transfer or other 
disposition of any of the Parent Shares must be made in 
conformity with the provisions of said Rule or be registered 
under the Act.  Affiliate acknowledges and agrees that (i) stop 
transfer instructions will be given to Parent's transfer agent 
with respect to the Parent Shares, and (ii) each certificate 
representing any of such shares shall bear a legend identical or 
similar in effect to the following legend (together with any 
other legend or legends required by applicable state securities 
laws or otherwise):

           "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT 
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE 
"ACT") AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, 
ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS REGISTERED UNDER THE ACT 
OR UNLESS AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE

ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT 
DATED AS OF _________ __, 1997, BETWEEN THE REGISTERED HOLDER 
HEREOF AND Lumisys Incorporated, A COPY OF WHICH AGREEMENT IS ON 
FILE AT THE PRINCIPAL OFFICES OF LUMISYS INCORPORATED"

      21.  Independence of Obligations.  The covenants and 
obligations of Affiliate set forth in this Agreement shall be 
construed as independent of any other agreement or arrangement 
between Affiliate, on the one hand, and the Company or Parent, on 

                                   A-4

the other.  The existence of any claim or cause of action by 
Affiliate against the Company or Parent shall not constitute a 
defense to the enforcement of any of such covenants or 
obligations against Affiliate.

      22.  Specific Performance.  Affiliate agrees that in the 
event of any breach or threatened breach by Affiliate of any 
covenant, obligation or other provision contained in this 
Agreement, Parent shall be entitled (in addition to any other 
remedy that may be available to Parent) to:  (a) a decree or 
order of specific performance or mandamus to enforce the 
observance and performance of such covenant, obligation or other 
provision; and (b) an injunction restraining such breach or 
threatened breach.

      23.  Indemnification.  Without in any way limiting any of 
the rights or remedies otherwise available to Parent, Affiliate 
shall hold harmless and indemnify Parent from and against, and 
shall compensate and reimburse Parent for, any loss, damage, 
injury, decline in value, lost opportunity, liability, exposure, 
claim, demand, settlement, judgment, award, fine, penalty, tax, 
fee, charge, cost or expense of any nature (whether or not 
relating to a third party claim) which is directly or indirectly 
suffered or incurred at any time by Parent or any of Parent's 
affiliates or to which Parent or any of Parent's affiliates 
otherwise becomes subject and that arises from any inaccuracy in 
or breach of any representation, warranty, covenant or obligation 
of Affiliate contained in this Agreement.

      24.  Other Agreements.  Nothing in this Agreement shall 
limit any of the rights or remedies of Parent under the 
Reorganization Agreement and nothing in the Reorganization 
Agreement shall limit any of the rights or remedies of Parent 
under this Agreement.

      25.  Notices.  Any notice or other communication required 
or permitted to be delivered to Affiliate or Parent under this 
Agreement shall be in writing and shall be deemed properly 
delivered, given and received when delivered (by hand, by

provision or part thereof shall, with respect to such 
circumstances and in such jurisdiction, be deemed amended to 
conform to applicable laws so as to be valid and enforceable to 
the fullest possible extent, (b) the invalidity or 
unenforceability of such provision or part thereof under such 
circumstances and in such jurisdiction shall not affect the 
validity or enforceability of such provision or part thereof 
under any other circumstances or in any other jurisdiction, and

Agreement, and each part of each provision of this Agreement is

any  ower, right, privilege or remedy under this Agreement, and 
no delay on the part of Parent in exercising any power, right, 
privilege or remedy under this Agreement, shall operate as a 
waiver of such power, right, privilege or remedy; and no single 
or partial exercise of any such power, right, privilege or remedy 
shall preclude any other or further exercise thereof or of any 
other power, right, privilege or remedy.  Parent shall not be 
deemed to have waived any claim arising out of this Agreement, or 
any power, right, privilege or remedy under this Agreement, 
unless the waiver of such claim, power, right, privilege or 
remedy is expressly set forth in a written instrument duly

shall not be applicable or have any effect except in the specific 
instance in which it is given.

          FORM OF CONTINUITY OF INTEREST CERTIFICATE


                     ("Stockholder") is aware that an Agreement 
and Plan of Merger and Reorganization dated as of September     , 
1997 (the "Reorganization Agreement") and related Certificate of 
Merger (together, the "Agreements") has been made and entered 
into by and among Lumisys Incorporated, a Delaware corporation 
("Parent"), SAC Acquisition Corporation, a Delaware corporation 
and a wholly owned subsidiary of Parent ("Merger Sub") and 
CompuRAD, Inc., a Delaware corporation (the "Company") providing 
for the merger of Merger Sub with and into the Company (the 
"Merger").  The Reorganization Agreement contemplates that, upon 
consummation of the Merger, (i) the Company's stockholders will 
receive shares of common stock, par value $.001 per share, of 
Parent ("Parent Common Stock") in exchange for their shares of 
common stock, par value $.01 per share, of the Company ("Company 
Common Stock") and (ii) the Company will become a wholly owned 
subsidiary of Parent.  It is accordingly contemplated that 
Stockholder will receive shares of Parent Common Stock in the 
Merger.

      38.  Stockholder represents, warrants and certifies to 
Parent, Merger Sub, the Company and the Company's Stockholders as 
follows:

           1.  Stockholder currently is the owner of       shares 
of Company Common Stock (the "Shares"), and did not acquire any 
of the Shares in contemplation of the Merger.

           2.  Stockholder has not engaged in a Sale (as defined 
below) of any shares of Company Common Stock in contemplation of 
the Merger.

           3.  Stockholder has no plan or intention to engage in 
a sale, exchange, transfer, distribution, redemption or reduction 
in any way of Stockholder's risk of ownership (by short sale or 
otherwise), or other disposition, directly or indirectly (such 
actions being collectively referred to herein as a "Sale") of 
more than [fifty percent (50%)] of the shares of Parent Common 
Stock to be received by Stockholder in the Merger.  (For purposes 
of the preceding sentence, shares of Company Common Stock (or the 
portion thereof) (i) with respect to which Stockholder will 
receive consideration in the Merger other than shares of Parent 
Common Stock (including cash to be received in lieu of fractional 
shares of Parent Common Stock) and/or (ii) with respect to which 
a Sale (A) occurred in contemplation of the Merger or (B) will 
occur prior to the Merger, shall be considered shares of Company 
Common Stock exchanged for shares of Parent Common Stock in the 
Merger and then disposed of pursuant to a plan).

           4.  Stockholder has no plan or intention to exercise 
dissenters' rights in connection with the Merger.

           5.  Stockholder is not aware of, or participating in, 
any plan or intention on the part of the stockholders of the 
Company to engage in a Sale or Sales of more than fifty percent 
(50%) of the shares of Parent Common Stock to be received in the 
Merger.  (For purposes of the preceding sentence, shares of 

                                   A-1

Company Common Stock (or the portion thereof) (i) with respect to 
which a stockholder of the Company receives consideration in the 
Merger other than shares of Parent Common Stock (including, 
without limitation, cash received pursuant to the exercise of 
dissenters' rights or in lieu of a fractional share of Parent 
Common Stock) or (ii) with respect to which a Sale occurs prior 
to and in contemplation of the Merger, shall be considered shares 
of outstanding Company Common Stock exchanged for shares of 
Parent Common Stock in the Merger and then disposed of pursuant 
to a plan).

           6.  Except to the extent written notification to the 
contrary is received by Parent and the Company from Stockholder 
prior to the consummation of the Merger, the representations, 
warranties and certifications contained herein shall be accurate 
at all times from the date hereof through the date on which the 
Merger is consummated.
	
           7.  Stockholder has consulted with such legal counsel 
and financial advisors as he has deemed appropriate in connection 
with the execution of this Certificate.

      39.  Stockholder understands that Parent, Merger Sub, the 
Company, and the Company's stockholders, as well as legal counsel 
to Parent, Merger Sub and the Company (in connection with 
rendering their opinions that the Merger will be a 
"reorganization" within the meaning of Section 368(a) of the 
Internal Revenue Code of 1986, as amended) will be relying on (a) 
the truth and accuracy of the representations, warranties and 
certifications contained herein and (b) the Stockholder's 
performance of the obligations set forth herein.

	Stockholder has executed this Certificate on           1997.

Re:  Employment Terms

Dear 			:

Lumisys Incorporated (the "Company") is pleased to offer you the 
position of President, effective upon the closing of the 
acquisition of CompuRAD, Inc. by the Company (the "Closing"), on 
the following terms, which terms shall be effective only upon the 
Closing.

1.  Reporting Duties

You will be responsible for all functional areas of the combined 
company, including duties customarily associated with the 
position and other duties as assigned by me.  You will work at 
our facility located in Tucson, Arizona.  Of course, the Company 
may change your position, duties, and work location from time to 
time as it deems necessary; provided that no such change shall 
occur prior to September 1998.

2.  Compensation

Your compensation will be $			 per month, less payroll 
deductions and all required withholdings.  You will be paid bi-
weekly (26 payment periods per year) and you will be eligible for 
the following standard Company benefits:  group medical, dental 
and life insurance, vacation and participation in the Company's 
401(k) and employee stock purchase plan.  Details about these 
benefit plans are available for your review.  The Company may 
modify compensation and benefits from time to time as it deems 
necessary.

3.  Bonus

You will also be eligible annually for a discretionary year-end 
bonus, in an amount to be determined by the Company's Board of 
Directors (the "Board") in its sole discretion.  You will earn 
this bonus if all of the following criteria are met:  (i) the 
Company must meet or exceed its planned revenue and profit 
objectives for the bonus year, as determined by the Board; (ii) 
your performance must meet or exceed expectations for your 
position, as determined by the Board; and (iii) you must remain 
an active employee through the end of the bonus year.  If your 
employment terminates for any reason before the end of the bonus 
year, you will not receive this bonus; no prorated bonus can be 
earned, provided however, that if you are terminated at any time 
in 1998 (unless you are terminated for "cause" as defined in 
Paragraph 8 below), you will receive a pro-rated bonus for the 

                                   A-1

year 1998.  In addition, if the Closing occurs after January 1, 
1998, any bonus for the year 1998 will be calculated to cover the 
period from January 1, 1998 as if you had been employed during 
that period.  It is currently expected that you will not receive 
a bonus from the Company for the services you performed during 
the year 1997. 


4.  Relocation Expenses

You will receive relocation benefits for your move from Arizona 
to California from the date of this Agreement to December 31, 
1998, under the terms of the Relocation Benefits Agreement, 
attached hereto as Exhibit B, up to a maximum reimbursement 
amount to be mutually agreed upon by the parties. 

5.  Company Policies regarding Confidential Information and Other 
Matters

As a Company employee, you will be expected to abide by Company 
rules and regulations, acknowledge in writing that you have read 
the Company's Employee Handbook, and sign and comply with the 
Proprietary Information and Inventions Agreement, attached hereto 
as Exhibit A, which prohibits unauthorized use or disclosure of 
Company proprietary information.   As required by law, this offer 
is subject to satisfactory proof of your right to work in the 
United States.

Normal working hours are from 8:00 a.m. to 5:00 p.m., Monday 
through Friday.  As an exempt salaried employee, you will be 
expected to work additional hours as required by the nature of 
your work assignments.  Except with the prior written consent of 
the Board, you will not during the term of your employment with 
the Company undertake or engage in any other employment, 
occupation or business enterprise.  You may engage in civic and 
not-for-profit activities so long as such activities do not 
materially interfere with the performance of your duties 
hereunder.  

6.  Restrictive Covenant

During the term of your employment, except as permitted by this 
paragraph, you agree not to acquire, assume or participate in, 
directly or indirectly, any position, investment or interest 
known by you to be adverse or antagonistic to the Company, its 
business or prospects, financial or otherwise.  During the term 
of your employment by the Company, including any period of salary 
continuation following your termination, as described below, you 
will not directly or indirectly, whether as an officer, director, 
stockholder, partner, proprietor, associate, representative, 
consultant, or in any capacity whatsoever engage in, become 
financially interested in, be employed by or have any business 
connection with any other person, corporation, firm, partnership 
or other entity whatsoever which competes with the Company, 
throughout the world, in any line of business engaged in (or 
planned to be engaged in) by the Company.  Notwithstanding the 
above, however, you may own, as a passive investor, securities of 
any competitor corporation, so long as your and your family's 
aggregate holdings in any one such corporation do not constitute 
more than 1% of the voting stock of such corporation.

                                   A-2          

7.  Non-Solicitation

While employed by the Company, and for one (1) year thereafter, 
you agree not to interfere with the business of the Company by:  
(i) soliciting, attempting to solicit, inducing, or otherwise 
causing any employee of the Company to terminate his or her 
employment with the Company; or (ii) directly or indirectly 
soliciting the business of any customer of the Company which at 
the time of termination or one year immediately prior thereto was 
listed on the Company's customer list.


8.  Termination

You may terminate your employment with the Company at any time 
and for any reason whatsoever simply by notifying the Company.  
Likewise, the Company may terminate your employment at any time 
and for any reason whatsoever, with or without cause or advance 
notice.  This at-will employment relationship cannot be changed 
except in a writing signed by a Company officer.  Notwithstanding 
the foregoing, in the event before the second anniversary of 
Closing the Company terminates your employment without "cause" or 
you terminate your employment for "good reason," the Company will 
continue, as severance, your base salary at its then current rate 
for a period of twelve (12) months following such termination.  
For the purposes of the foregoing, "cause" means misconduct, 
including:  (i) the current use of illegal drugs; (ii) indictment 
for any crime involving moral turpitude, fraud or 
misrepresentation; (iii) commission of any act which would 
constitute a felony and which would adversely impact the business 
or reputation of the Company; (iv) fraud; (v) misappropriation or 
embezzlement of Company funds or property; (vi) willful conduct 
which is materially injurious to the reputation, business or 
business relationships of the Company; (viii) your failure to 
perform your responsibilities and/or duties provided that you 
have thirty days (from the date that the Company delivers a 
written notice to you describing your failure to perform) to cure 
any failure to perform; or (ix) a material violation of any of 
the provisions of this employment offer letter or of the attached 
Proprietary Information and Inventions Agreement.  For purposes 
of the foregoing, "good reason" means: (i) material diminution in 
your duties or salary (except in connection with a fairly 
administered across the board salary reduction plan adopted by 
the Board) or (ii) relocation outside of the San Francisco Bay 
Area (other than back to the Tucson area if the Company provides 
relocation expenses for such relocation).

9.  Entire Agreement

This letter, including Exhibits A, B, and C, constitutes the 
complete, final and exclusive embodiment of the entire agreement 
between you and the Company with respect to the terms and 
conditions of your employment.  This letter agreement is entered 
into without reliance on any promise or representation, written 
or oral, other than those expressly contained herein.  It may not 
be modified except in a writing signed by you and a duly 
authorized officer of the Company. 
The employment terms in this letter supersede any other 
agreements or promises made to you by anyone, whether oral or 
written.  In addition, all employment contracts, terms of 
employment, offer letters or similar agreements, arrangements or 
understandings between you and CompuRAD, Inc. terminate as of the 
Closing.  

                                   A-3

In consideration of the terms of the Closing and this offer 
letter, you hereby agree to release and hold harmless CompuRAD, 
Inc., the Company and their officers, directors and agents for 
any and all acts or omissions relating to your employment with 
CompuRAD, Inc. prior to the Closing and do so by executing the 
Release attached hereto as Exhibit C.

Please sign and date this letter, and return it to me, if you 
wish to accept employment at the Company under the terms 
described above.  

We look forward to your favorable reply and to a productive and 
enjoyable work relationship.

Sincerely,

                     LUMISYS INCORPORATED

                  PROPRIETARY INFORMATION
                  AND INVENTIONS AGREEMENT


      In consideration of my employment or continued employment 
by Lumisys Incorporated (the "Company"), and the compensation now 
and hereafter paid to me, I hereby agree as follows:

      40.  Recognition of Company's Rights; Nondisclosure.  At 
all times during the term of my employment and thereafter, I will 
hold in strictest confidence and will not disclose, use, lecture 
upon or publish any of the Company's Proprietary Information 
(defined below), except as such disclosure, use or publication 
may be required in connection with my work for the Company, or 
unless an officer of the Company expressly authorizes such in 
writing.  I hereby assign to the Company any rights I may have or 
acquire in such Proprietary Information and recognize that all 
Proprietary Information shall be the sole property of the Company 
and its assigns and the Company and its assigns shall be the sole 
owner of all trade secret rights, patent rights, copyrights, mask 
work rights and all other rights throughout the world 
(collectively, "Proprietary Rights") in connection therewith.

           The term "Proprietary Information" shall mean trade 
secrets, confidential knowledge, data or any other proprietary 
information of the Company.  By way of illustration but not 
limitation, "Proprietary Information" includes (a) trade secrets, 
inventions, mask works, ideas, processes, formulas, source and 
object codes, data, programs, other works of authorship, know-
how, improvements, discoveries, developments, designs and 
techniques (hereinafter collectively referred to as 
"Inventions"); and (b) information regarding plans for research, 
development, new products, marketing and selling, business plans, 
budgets and unpublished financial statements, licenses, prices 
and costs, suppliers and customers; and information regarding the 
skills and compensation of other employees of the Company.

      41.  Third Party Information.  I understand, in addition, 
that the Company has received and in the future will receive from 
third parties confidential or proprietary information ("Third 
Party Information") subject to a duty on the Company's part to 
maintain the confidentiality of such information and to use it 
only for certain limited purposes.  During the term of my 
employment and thereafter, I will hold Third Party Information in 
the strictest confidence and will not disclose (to anyone other 
than Company personnel who need to know such information in 
connection with their work for the Company) or use, except in 
connection with my work for the Company, Third Party Information 
unless expressly authorized by an officer of the Company in 
writing.

      42.  Assignment of Inventions.

           42.1  Assignment.  I hereby assign to the Company all 
my right, title and interest in and to any and all Inventions 
(and all Proprietary Rights with respect thereto) whether or not 
patentable or registrable under copyright or similar statutes, 
made or conceived or reduced to practice or learned by me, either 
alone or jointly with others, during the period of my employment 
with the Company.  Inventions assigned to or as directed by the 
Company by this paragraph 3 are hereinafter referred to as 
"Company Inventions."  I recognize that this Agreement does not 
require assignment of any invention which qualifies fully for 
protection under Section 2870 of the California Labor Code 
(hereinafter "Section 2870"), which provides as follows:

                (a)  Any provision in an employment agreement 
which provides that an employee shall assign, or offer to assign, 
any of his or her rights in an invention to his or her employer 
shall not apply to an invention that the employee developed 
entirely on his or her own time without using the employer's 
equipment, supplies, facilities, or trade secret information 
except for those inventions that either:

                     (i)  Relate at the time of conception or 
reduction to practice of the invention to the employer's 
business, or actual or demonstrably anticipated research or 
development of the employer.

                     (ii)  Result from any work performed by the 
employee for the employer.

                (b)  To the extent a provision in an employment 
agreement purports to require an employee to assign an invention 
otherwise excluded from being required to be assigned under 
subdivision (i), the provision is against the public policy of 
this state and is unenforceable.

           42.2  Government.  I also assign to or as directed by 
the Company all my right, title and interest in and to any and 
all Inventions, full title to which is required to be in the 
United States by a contract between the Company and the United 
States or any of its agencies.

           42.3  Works for Hire.  I acknowledge that all original 
works of authorship which are made by me (solely or jointly with 
others) within the scope of my employment and which are 
protectable by copyright are "works made for hire," as that term 
is defined in the United States Copyright Act (17 U.S.C., 
Section 101).

      43.  Enforcement of Proprietary Rights.  I will assist the 
Company in every proper way to obtain and from time to time 
enforce United States and foreign Proprietary Rights relating to 
Company Inventions in any and all countries.  To that end I will 
execute, verify and deliver such documents and perform such other 
acts (including appearances as a witness) as the Company may 
reasonably request for use in applying for, obtaining, 
perfecting, evidencing, sustaining and enforcing such Proprietary 
Rights and the assignment thereof.  In addition, I will execute, 
verify and deliver assignments of such Proprietary Rights to the 
Company or its designee.  My obligation to assist the Company 
with respect to Proprietary Rights relating to such Company 
Inventions in any and all countries shall continue beyond the 
termination of my employment, but the Company shall compensate me 
at a reasonable rate after my termination for the time actually 
spent by me at the Company's request on such assistance.

           In the event the Company is unable for any reason, 
after reasonable effort, to secure my signature on any document 
needed in connection with the actions specified in the preceding 
paragraph, I hereby irrevocably designate and appoint the Company 
and its duly authorized officers and agents as my agent and 
attorney in fact, which appointment is coupled with an interest, 
to act for and in my behalf to execute, verify and file any such 
documents and to do all other lawfully permitted acts to further 
the purposes of the preceding paragraph with the same legal force 
and effect as if executed by me.  I hereby waive and quitclaim to 
the Company any and all claims, of any nature whatsoever, which I 
now or may hereafter have for infringement of any Proprietary 
Rights assigned hereunder to the Company.

      44.  Obligation to the Company After Termination.  I agree 
to keep and maintain adequate and current records (in the form of 
notes, sketches, drawings and in any other form that may be 
required by the Company) of all Proprietary Information developed 
by me and all Inventions made by me during the period of my 
employment at the Company, which records shall be available to 
and remain the sole property of the Company at all times.

      45.  Prior Inventions.  Inventions, if any, patented or 
unpatented, which I made prior to the commencement of my 
employment with the Company are excluded from the scope of this 
Agreement.  To preclude any possible uncertainty, I have set 
forth on Attachment 1 attached hereto a complete list of all 
Inventions that I have, alone or jointly with others, conceived, 
developed or reduced to practice or caused to be conceived, 
developed or reduced to practice prior to the commencement of my 
employment with the Company, that I consider to be my property or 
the property of third parties and that I wish to have excluded 
from the scope of this Agreement.  If disclosure of any such 
Invention on Attachment 1 would cause me to violate any prior 
confidentiality agreement, I understand that I am not to list 
such Inventions in Attachment 1 but am to inform the Company that 
all such Inventions have not been listed for that reason.

      46.  No Improper Use of Materials.  During my employment by 
the Company I will not improperly use or disclose any 
confidential information or trade secrets, if any, of any former 
employer or any other person to whom I have an obligation of 
confidentiality, and I will not bring onto the premises of the 
Company any unpublished documents or any property belonging to 
any former employer or any other person to whom I have an 
obligation of confidentiality unless consented to in writing by 
that former employer or person.  I will use in the performance of 
my duties only information which is generally known and used by 
persons with training and experience comparable to my own, which 
is common knowledge in the industry or otherwise legally in the 
public domain, or which is otherwise provided or developed by the 
Company.

      47.  No Conflicting Obligation.  I represent that my 
performance of all the terms of this Agreement and as an employee 
of the Company does not and will not breach any agreement to keep 
in confidence information acquired by me in confidence or in 
trust prior to my employment by the Company.  I have not entered 
into, and I agree I will not enter into, any agreement either 
written or oral in conflict herewith.

      48.  Return of Company Documents.  When I leave the employ 
of the Company, I will deliver to the Company any and all 
drawings, notes, memoranda, specifications, devices, formulas, 
and documents, together with all copies thereof, and any other 
material containing or disclosing any Company Inventions, Third 
Party Information or Proprietary Information of the Company.  I 
further agree that any property situated on the Company's 
premises and owned by the Company, including disks and other 
storage media, filing cabinets or other work areas, is subject to 
inspection by Company personnel at any time with or without 
notice.  Prior to leaving, I will cooperate with the Company in 
completing and signing the Company's termination statement for 
technical and management personnel.

      49.  Legal and Equitable Remedies.  Because my services are 
personal and unique and because I may have access to and become 
acquainted with the Proprietary Information of the Company, the 
Company shall have the right to enforce this Agreement and any of 
its provisions by injunction, specific performance or other 
equitable relief, without bond and without prejudice to any other 
rights and remedies that the Company may have for a breach of 
this Agreement.

      50.  Notices.  Any notices required or permitted hereunder 
shall be given to the appropriate party at the address specified 
below or at such other address as the party shall specify in 
writing.  Such notice shall be deemed given upon personal 
delivery to the appropriate address or if sent by certified or 
registered mail, three days after the date of mailing.

      51.  General Provisions.

           51.1  Governing Law.  This Agreement will be governed 
by and construed according to the laws of the State of 
California.

           51.2  Entire Agreement.  This Agreement is the final, 
complete and exclusive agreement of the parties with respect to 
the subject matter hereof and supersedes and merges all prior 
discussions between us.  No modification of or amendment to this 
Agreement, nor any waiver of any rights under this Agreement, 
will be effective unless in writing and signed by the party to be 
charged.  Any subsequent change or changes in my duties, salary 
or compensation will not affect the validity or scope of this 
Agreement.  As used in this Agreement, the period of my 
employment includes any time during which I may be retained by 
the Company as a consultant.

           51.3  Severability.  If one or more of the provisions 
in this Agreement are deemed unenforceable by law, then such 
provision will be deemed stricken from this Agreement and the 
remaining provisions will continue in full force and effect.

           51.4  Successors and Assigns.  This Agreement will be 
binding upon my heirs, executors, administrators and other legal 
representatives and will be for the benefit of the Company, its 
successors, and its assigns.

           51.5  Survival.  The provisions of this Agreement 
shall survive the termination of my employment and the assignment 
of this Agreement by the Company to any successor in interest or 
other assignee.

           51.6  Employment.  I agree and understand that nothing 
in this Agreement shall confer any right with respect to 
continuation of employment by the Company, nor shall it interfere 
in any way with my right or the Company's right to terminate my 
employment at any time, with or without cause.

           51.7  Waiver.  No waiver by the Company of any breach 
of this Agreement shall be a waiver of any preceding or 
succeeding breach.  No waiver by the Company of any right under 
this Agreement shall be construed as a waiver of any other right. 
 The Company shall not be required to give notice to enforce 
strict adherence to all terms of this Agreement.

      This Agreement shall be effective as of the first day of my 
employment with the Company, namely:              , 19  .

I HAVE READ THIS AGREEMENT CAREFULLY AND UNDERSTAND ITS TERMS.  I 
HAVE COMPLETELY FILLED OUT ATTACHMENT 1 TO THIS AGREEMENT.

               Relocation Benefits Agreement


Effective on                1997 (the "Effective Date"),
            ----------------                                 
             (Start Date)
I,
  ----------------------------------------
                (Name)
hereby agree to the following terms and conditions with respect 
to all relocation costs paid to me or on my behalf by Lumisys 
Incorporated (the "Company"), whether by reimbursement to me or 
by direct payment to third parties, in connection with my 
relocation from Arizona to my new home in                , 
California (the "Relocation Costs"):  

1.  If I remain a President of the Company for 12 months from the 
Effective Date, I shall have no obligation to repay any of the 
Relocation Costs.

2.  If my employment terminates for "cause" or without "good 
reason" within one year from the effective date, I agree to repay 
to the Company a portion of the Relocation Costs, including tax 
assistance payments or other amounts paid to federal or state tax 
agencies as withholding or other credit against taxes, to be 
calculated as follows:

    For each full month of full-time employment, the Company will 
forgive 1/12 of my Relocation Costs.  The remaining unforgiven 
Relocation Costs are due and payable to the Company on demand.

3.  I understand that all reimbursements and allowances paid to 
me or on my behalf as Relocation Costs, including tax assistance 
payments and amounts withheld as payroll deductions, in 
connection with my relocation must be included as a part of my 
gross income and therefore may be subject to tax.  If I am 
required under paragraph 2 of this agreement to repay Relocation 
Costs to the Company, I will repay the entire amount determined 
under paragraph 2, including tax assistance payments and amounts 
withheld as payroll deductions.

    I also understand that my ability to deduct a portion of my 
Relocation Costs is subject to specific limits and other IRS 
requirements, including the requirement that I must be able to 
substantiate my expenses by keeping copies of my receipts.  I 
UNDERSTAND THAT IF I AM AUDITED BY THE IRS OR ANY STATE TAX 
AGENCY, I ALONE AND NOT THE COMPANY WILL BE LIABLE FOR ANY TAXES, 
INTEREST OR PENALTIES DUE IF ANY CLAIMED DEDUCTIONS ARE DENIED 
FOR ANY REASON, INCLUDING IF I FAIL TO KEEP COPIES OF RECEIPTS.  
I understand that I cannot rely on the Company or any officer or 
employee of the Company for advice regarding the proper tax 
treatment of my Relocation Costs, and that I am responsible for 
obtaining independent advice from my own personal tax advisor.

4.  I understand that nothing in this agreement assures me of a 
continuing position with the Company, or in any way changes the 
Company's right to end the employment relationship as it deems 
necessary.

5.  If I am obligated under this agreement to repay the Company 
for Relocation Costs, I hereby authorize the Company to deduct 
the entire amount due from my final paycheck, including from any 
vacation pay due.

6.  Before submitting expenses for reimbursement as Relocation 
Costs, I will inform the Company whether my spouse is eligible 
for relocation benefits from another employer, and if so, the 
terms of those benefits.  If my spouse is eligible for any of the 
same relocation benefits which the Company has offered me, I will 
only receive one-half of any such benefits from the Company.

                          RELEASE


      Except as otherwise set forth in this Release, I hereby 
release, acquit and forever discharge CompuRAD, Inc. (the 
"Company"), its parents and subsidiaries, and their officers, 
directors, agents, servants, employees, attorneys, shareholders, 
successors, assigns and affiliates, of and from any and all 
claims, liabilities, demands, causes of action, costs, expenses, 
attorneys fees, damages, indemnities and obligations of every 
kind and nature, in law, equity, or otherwise, known and unknown, 
suspected and unsuspected, disclosed and undisclosed, arising out 
of or in any way related to agreements, events, acts or conduct 
at any time prior to and including the execution date of this 
Release, including but not limited to:  all such claims and 
demands directly or indirectly arising out of or in any way 
connected with my employment with the Company or the termination 
of that employment; claims or demands related to salary, bonuses, 
commissions, stock, stock options, or any other ownership 
interests in the Company, vacation pay, fringe benefits, expense 
reimbursements, severance pay, or any other form of compensation; 
claims pursuant to any federal, state or local law, statute, or 
cause of action including, but not limited to, the federal Civil 
Rights Act of 1964, as amended; the federal Americans with 
Disabilities Act of 1990; the federal Age Discrimination in 
Employment Act of 1967, as amended ("ADEA"); the California Fair 
Employment and Housing Act, as amended; the Arizona Civil Rights 
Act, as amended; tort law; contract law; wrongful discharge; 
discrimination; harassment; fraud; defamation; emotional 
distress; and breach of the implied covenant of good faith and 
fair dealing.

      I acknowledge that I am knowingly and voluntarily waiving 
and releasing any rights I may have under the ADEA, as amended.  
I also acknowledge that the consideration given for the waiver 
and release in the preceding paragraph hereof is in addition to 
anything of value to which I was already entitled.  I further 
acknowledge that I have been advised by this writing, as required 
by the ADEA, that:  (a) my waiver and release do not apply to any 
rights or claims that may arise after the execution date of this 
Release; (b) I have been advised hereby that I have the right to 
consult with an attorney prior to executing this Release; (c) I 
have twenty-one (21) days to consider this Release (although I 
may choose to voluntarily execute this Release earlier); (d) I 
have seven (7) days following the execution of this Release by 
the parties to revoke the Release; and (e) this Release shall not 
be effective until the date upon which the revocation period has 
expired, which shall be the eighth day after this Release is 
executed by me, provided that the Company has also executed this 
Release by that date ("Effective Date").

      In giving this release, which includes claims which may be 
unknown to me at present,  I acknowledge that I have read and 
understand Section 1542 of the California Civil Code which reads 
as follows:  "A general release does not extend to claims which 
the creditor does not know or suspect to exist in his favor at 
the time of executing the release, which if known by him must 
have materially affected his settlement with the debtor." I 
hereby expressly waive and relinquish all rights and benefits 
under that section and any law of any jurisdiction of similar 
effect with respect to my release of any claims I may have 
against the Company.

                         EXHIBIT G

                      VOTING AGREEMENT


      This Voting Agreement is entered into as of September 28, 
1997 by and between  Lumisys Incorporated, a Delaware corporation 
("Parent"), and                          ("Stockholder").

                          Recitals

      52.  Parent, SAC Acquisition Corporation, a Delaware 
corporation and a wholly owned subsidiary of Parent ("Merger 
Sub"), and CompuRAD, Inc., a Delaware corporation (the 
"Company"), are entering into an Agreement and Plan of Merger and 
Reorganization of even date herewith (as amended from time to 
time, the "Reorganization Agreement"; capitalized terms used but 
not otherwise defined in this Voting Agreement have the meanings 
assigned to such terms in the Reorganization Agreement), which 
provides (subject to the conditions set forth therein) for the 
merger of Merger Sub with and into the Company (the "Merger").

      53.  As of the date hereof, Stockholder owns the number of 
shares of Company Common Stock set forth below Stockholder's name 
on the signature page hereto (all such shares, together with any 
shares of Company Common Stock or other shares of capital stock 
of the Company that may hereafter be acquired by Stockholder, 
being referred to herein as the "Subject Shares").

      54.  As a condition to the willingness of Parent and Merger 
Sub to enter into the Reorganization Agreement, Parent and Merger 
Sub have required that Stockholder agree, and in order to induce 
Parent and Merger Sub to enter into the Reorganization Agreement 
Stockholder has agreed, to enter into this Voting Agreement.


                         Agreement

      The parties to this Voting Agreement, intending to be 
legally bound, agree as follows:

55.  Transfer of Subject Shares

      55.1  Transfer of Voting Rights.  Stockholder covenants and 
agrees that, prior to the earlier to occur of: (i) the Effective 
Time, or (ii) the valid termination of the Reorganization 
agreement (the "Expiration Date"), and except as otherwise 
contemplated hereby, Stockholder will not deposit any of the 
Subject Shares into a voting trust or grant a proxy or enter into 
a voting agreement or similar agreement with respect to any of 
the Subject Shares.

      55.2  Obligations of Transferees.  Each transferee or any 
subsequent transferee of the Subject Shares or any interest in 
such Subject Shares, shall hold such Subject Shares or interest 
in the Subject Shares subject to all the provisions of this 
Voting Agreement.  Each transferee shall sign a counterpart of 
this Agreement, agreeing to be bound by the terms and conditions 
hereof, prior to receipt of any Subject Shares.

56.  Voting of Subject Shares

      56.1  Pre-Termination Voting Agreement.  Without in any way 
limiting the Stockholder's right to vote the Subject Shares in 
his sole discretion on any other matters that may be submitted to 
a stockholder vote, consent or other approval (including by 
written consent), at any meeting of the stockholders of the 
Company called to vote upon the Merger and the Reorganization 
Agreement or at any adjournment thereof or in any other 
circumstances upon which a vote, consent or other approval 
(including by written consent) with respect to the Merger and the 
Reorganization Agreement is sought, the Stockholder hereby agrees 
that, prior to the Expiration Date, at any meeting of the 
stockholders of the Company, however called, and in any written 
action by consent of stockholders of the Company, Stockholder 
shall vote the Subject Shares in favor of:  (i) the Merger, (ii) 
the execution and delivery by the Company of the Reorganization 
Agreement, (iii) the adoption and approval of the terms thereof 
and (iv) in favor of each of the other actions contemplated by 
the Reorganization Agreement and any action required in 
furtherance hereof or thereof. 

Prior to the Expiration Date, Stockholder shall not enter into 
any agreement or understanding with any Person to vote or give 
instructions with respect to the Subject Shares regarding the 
Merger and the Reorganization Agreement, other than any agreement 
or understanding to vote or give instructions in favor of the 
Merger and the Reorganization Agreement.

      56.2  Proxy; Further Assurances.  Contemporaneously with 
the execution of this Voting Agreement, Stockholder shall deliver 
to Parent a proxy in the form attached hereto as Exhibit A, which 
shall be irrevocable to the fullest extent permitted by law, with 
respect to the Subject Shares (the "Proxy").
 
57.  Waiver of Appraisal Rights.  

      Stockholder hereby waives any rights of appraisal and any 
dissenters' rights that Stockholder may have in connection with 
the Merger.

58.  No Solicitation

      (i)  solicit, initiate, encourage or induce the making, 
submission or announcement of any Acquisition Proposal or take 
any action that could reasonably be expected to lead to an 
Acquisition Proposal; (ii) furnish any information regarding the 
Company to any Person in connection with or in response to an 
Acquisition Proposal or potential Acquisition Proposal; (iii) 
engage in discussions with any Person with respect to any 
Acquisition Proposal; (iv)  approve, endorse or recommend any 
Acquisition Proposal; or (v) enter into any letter of intent or 
other similar document or any Contract contemplating or otherwise

immediately cease any existing discussions with any Person that 
relate to any Acquisition Proposal.  Notwithstanding the 
foregoing, Stockholder shall not be prevented from taking any 
action that is not prohibited under Section 4.4 of the 
Reorganization Agreement, whether he is acting in his capacity as 
a Stockholder of the Company or as an officer or director of the 
Company; provided that nothing herein shall be deemed to excuse 
Stockholder's performance of his voting obligations hereunder. 

59.  Representations and Warranties of Stockholder

      Stockholder hereby represents and warrants to Parent as 
follows:

      59.1  Authorization, etc.  Stockholder has all requisite

acceleration or cancellation of, or result in the creation of an 
Encumbrance on the Subject Shares pursuant to, any Contract to 
which Stockholder is a party or by which Stockholder or any of 
his properties is bound or affected.

           (b)  The execution and delivery of this Voting 
Agreement by Stockholder do not, and the performance of this 
Voting Agreement by Stockholder will not, require any Consent of 
any Person.

      59.3  Title to Subject Shares.  Stockholder owns of record

consummation of the Merger as if made on that date.

60.  Covenants of Stockholder

      60.1  Further Assurances.  From time to time and without 
additional consideration, Stockholder will execute and deliver,

instruments as Parent may reasonably request for the purpose of 
effectively carrying out and furthering the intent of this Voting 
Agreement.

party claim) which are directly or indirectly suffered or 
incurred at any time by Parent, or to which Parent otherwise 
becomes subject, and that arise from or are directly or 
indirectly connected with any breach of any representation, 
warranty, covenant or obligation of Stockholder contained herein.

Agreement which is invalid or unenforceable in any jurisdiction

Voting Agreement shall be binding upon and shall inure to the 
benefit of (i) Stockholder and his heirs, successors and assigns 
and (ii) Parent and its successors and assigns.  Notwithstanding 
anything contained in this Voting Agreement to the contrary,

intended to confer on any Person other than the parties hereto or 
their respective heirs, successors and assigns any rights, 
remedies, obligations or liabilities under or by reason of this 
Voting Agreement.

      61.8  Specific Performance.  The parties hereto agree that

is accordingly agreed that Parent shall be entitled to an 
injunction or injunctions to prevent breaches of this Voting

               Lumisys to Acquire CompuRAD


     Transaction to create a leading supplier of Medical Image
                        Management components

Sunnyvale, California (September 29, 1997) - Lumisys, Inc. 
(NASDAQ:LUMI) and CompuRAD, Inc. (NASDAQ:COMD) today announced 
that they have entered into a definitive agreement for Lumisys to 
acquire CompuRAD, a leading provider of Teleradiology and PACS 
software in a stock for stock merger.  The combined company will 
focus on offering both hardware and software components to Medical 
Image Management system suppliers, OEMs and VARs.

This acquisition is expected to qualify as a tax free 
reorganization, and is expected to be accounted for as a pooling 
of interests.  The consummation of the acquisition is subject to 
certain conditions, including stockholder approval for both 
companies.  The transaction is anticipated to close during the 
first quarter of 1998.  Under the terms of the agreement, CompuRAD 
stockholders will receive .928 shares of Lumisys common stock for 
each share of common stock of CompuRAD.  Dr. Phillip Berman, 
Chairman of the Board, President and Chief Executive Officer of 
CompuRAD, and David Lapan, MD, CompuRAD Board of Directors member, 
will join the Lumisys Board of Directors.  Dr. Phillip Berman will 
serve as President and Stephen Weiss, Chief Executive Officer of 
Lumisys, will serve as the Chief Executive Officer of the combined 
company.

"In bringing together these two companies, we will be able to 
offer more products to our customers and increase long-term 
opportunities for employees,"  said Stephen Weiss.  Weiss added, 
"By increasing the software capabilities of our core products, we 
also will be able to offer our customers a new generation of 
'intelligent'  medical imaging appliances."

"We believe the combined companies will be able to deliver 
customers a unique combination of hardware, software, services 
and, ultimately, appliances" said Dr. Berman.  Dr. Berman added 
"this combination will also allow us to leverage the growing 
opportunities in the closely-related nuclear medicine, cardiology 
and clinical information market segments."

Lumisys designs, manufactures and markets a family of precision 
digitizers that convert medical images on film or video into 
digital format.  The Company's digitizers process images from all 
commercially available medical imaging modalities, including x-
ray, CT, MRI, ultrasound and nuclear medicine.  Lumisys' video 
digitization and compression products also have applications in 
scientific and industrial inspection, broadcast video and 
multimedia imaging.  Additional information on Lumisys is 
available at www.lumisys.com.

CompuRAD is a leading provider of Teleradiology and PACS software 
products designed to capture, distribute, manage, store and view 
radiology images to enable faster patient diagnosis and treatment. 
 CompuRAD also offers an innovative Clinical Data Repository and 
Access product called ClinicalWare which combines 
Internet/Intranet and Object technologies.  Additional information 
on CompuRAD is available at www.compurad.com.

This press release contains forward looking statements that 
involve risks and uncertainties, including those relating to the 
possible inability to complete the acquisition as scheduled, or at 
all.  Assuming completion of the acquisition, such risks and 
uncertainties include risks that integration of operations, 
technologies and products of the combining companies might not 
occur as anticipated; that management's attention might be 
diverted from day to day business activities; and that greater 
than normal employee turnover might occur.  In addition, there are 
normal risks and uncertainties associated with Lumisys' and 
CompuRAD's business, including the timely development, acceptance 
and pricing of new products and the impact of competitive 
conditions as well as the other risks detailed from time to time 
in the SEC reports of Lumisys and CompuRAD, including the report 
on Form 10-Q for the quarter ended June 30, 1997 for Lumisys and 
the report on Form 10-Q for the quarter ended June 30, 1997 for 
CompuRAD.

entire agreement between the parties with respect to the subject 
matter hereof and thereof and supersede all prior agreements and 
understandings between the parties with respect thereto.  No 
addition to or modification of any provision of this Voting 
Agreement shall be binding upon either party hereto unless made in 
writing and signed by both parties hereto.  The parties hereto 
waive trial by jury in any action at law or suit in equity based 
upon, or arising out of, this Voting Agreement or the subject 
matter hereof.

      7.7. Assignment; Binding Effect.  Except as provided herein, 
neither this Voting Agreement nor any of the rights, interests or 
obligations hereunder shall be assigned by either of the parties 
hereto (whether by operation of law or otherwise) without the 
prior written consent of the other party, except that Parent may 
assign all or any of its rights hereunder to any affiliate of 
Parent.  Subject to the preceding sentence, this Voting Agreement 
shall be binding upon and shall inure to the benefit of (i) 
Stockholder and his heirs, successors and assigns and (ii) Parent 
and its successors and assigns.  Notwithstanding anything 
contained in this Voting Agreement to the contrary, nothing in 
this Voting Agreement, expressed or implied, is intended to confer 
on any Person other than the parties hereto or their respective 
heirs, successors and assigns any rights, remedies, obligations or 
liabilities under or by reason of this Voting Agreement.

      7.8. Specific Performance.  The parties hereto agree that 
irreparable damage would occur in the event that any of the 
provisions of this Voting Agreement was not performed in 
accordance with its specific terms or was otherwise breached.  It 
is accordingly agreed that Parent shall be entitled to an 
injunction or injunctions to prevent breaches of this Voting 
Agreement and to enforce specifically the terms and provisions 
hereof in any Delaware court or other court of proper 
jurisdiction, this being in addition to any other remedy to which 
Parent is entitled at law or in equity.

      7.9. Other Agreements.  Nothing in this Voting Agreement shall 
limit any of the rights or remedies of Parent or any of the 
obligations of Stockholder under any Affiliate Agreement between 
Parent and Stockholder or any other agreement.  

      7.10. Governing Law.  This Voting Agreement shall be governed in 
all respects by the laws of the State of Delaware, as applied to 
contracts entered into and to be performed entirely within the 
State of Delaware.

      7.11. Counterparts.  This Voting Agreement may be executed by the 
parties hereto in separate counterparts, each of which when so 
executed and delivered shall be an original, but all such 
counterparts shall together constitute one and the same 
instrument.  

      7.12. Construction.

            (a) Headings of the Sections of this Voting Agreement are 
for the convenience of the parties only, and shall be given no 
substantive or interpretive effect whatsoever.

            (b) For purposes of this Voting Agreement, whenever the 
context requires: the singular number shall include the plural, and vice 
versa; the masculine gender shall include the feminine and neuter 
genders; the feminine gender shall include the masculine and 
neuter genders; and the neuter gender shall include masculine and 
feminine genders.

            (c) The parties hereto agree that any rule of construction 
to the effect that ambiguities are to be resolved against the drafting 
party shall not be applied in the construction or interpretation 
of this Voting Agreement.

            (d) As used in this Voting Agreement, the words "include" 
and "including," and variations thereof, shall not be deemed to be 
terms of limitation, but rather shall be deemed to be followed by 
the words "without limitation."

            (e) Except as otherwise indicated, all references in this 
Voting Agreement to "Sections" and "Exhibits" are intended to refer to 
Sections of this Voting Agreement and Exhibits to this Voting 
Agreement.

                           Irrevocable Proxy


      The undersigned stockholder of CompuRAD, Inc., a Delaware 
corporation (the "Company"), hereby irrevocably (to the fullest 
extent permitted by law) appoints and constitutes ___________________, 
_________________ and Lumisys, Incorporated, a Delaware corporation 
("Parent"), and each of them, the attorneys and proxies of the 
undersigned with full power of substitution and resubstitution, to the 
full extent of the undersigned's rights with respect to (i) the shares 
of capital stock of the Company owned by the undersigned as of the date 
of this proxy, which shares are specified on the final page of this 
proxy and (ii) any and all other shares of capital stock of the Company 
which the undersigned may acquire after the date hereof.  (The shares of 
the capital stock of the Company referred to in clauses (i) and (ii) 
of the immediately preceding sentence are collectively referred to as 
the "Shares.")  Upon the execution hereof, all prior proxies given by 
the undersigned with respect to any of the Shares are hereby revoked, 
and no subsequent proxies will be given with respect to any of the

      This proxy is irrevocable and is coupled with an interest.  
This proxy is granted in connection with the Voting Agreement of

Agreement") and in consideration of Parent entering into the

herewith among Parent,  SAC Acquisition Corporation, a Delaware 
corporation and wholly owned subsidiary of Parent, and the Company 
(the "Reorganization Agreement").  Capitalized terms used but not 
otherwise defined in this proxy have the meanings assigned to such 
terms in the Reorganization Agreement.  

      The attorneys and proxies named above will be empowered, and 
may exercise this proxy, to vote the Shares at any time at any 
meeting of the stockholders of the Company, however called, or in 
any written action by consent of stockholders of the Company, 
until the earlier to occur of the valid termination of the 
Reorganization Agreement or the Effective Time, as follows: (i) in 
favor of the Merger, (ii) in favor of the execution and delivery 
by the Company of the Reorganization Agreement and the adoption 
and approval of the terms thereof and (iii) in favor of each of 
the other actions contemplated by the Reorganization Agreement and 
any action required in furtherance hereof or thereof.




      This proxy shall be binding upon the heirs, successors and 
assigns of the undersigned (including any transferee of any of the 
Shares).
