                          INSIGHT HEALTH SERVICES CORP.
                         1998 EMPLOYEE STOCK OPTION PLAN

         InSight Health Services Corp., a Delaware corporation 
("Corporation") sets forth herein the terms of the InSight Health Services 
Corp. 1998 Employee Stock Option Plan (the "Plan") as follows:

1.       PURPOSE

         The Plan is intended to advance the interests of the Corporation by 
providing the individuals listed in Attachment 1 hereto ("Optionees") an 
inducement essential to enter into executive employment agreements with the 
Corporation and with an opportunity to develop a proprietary interest in the 
Corporation, which will thereby create strong performance incentives for such 
individuals to maximize the growth and success of the Corporation and its 
subsidiaries, and will encourage such individuals to remain in the employ of 
the Corporation, or any of its subsidiaries. Options granted under the Plan 
("Options") shall not constitute "incentive stock options" within the meaning 
of section 422 of the Internal Revenue Code of 1986, as amended from time to 
time ("Code").

2.      ADMINISTRATION

         Except as otherwise specifically provided herein, the Plan shall be 
administered by the Compensation Committee ("Committee") of the Board of 
Directors ("Board") of the Corporation, which shall have the full power and 
authority to take all actions, and to make all determinations required or 
provided for under the Plan or any Option granted or Option Agreement (as 
defined in Section 5 below) entered into hereunder, and all such other 
actions and determinations not inconsistent with the specific terms and 
provisions of the Plan deemed by the Committee to be necessary or appropriate 
to the administration of the Plan or any Option granted or Option Agreement 
entered into hereunder; provided however, that the Committee may not alter, 
amend or modify the express provisions of the Plan. The interpretation and 
construction by the Committee of any provision of the Plan or of any Option 
granted or Option Agreement entered into hereunder shall be final, binding 
and conclusive.

         The Board may remove members, add members, and fill vacancies on the 
Committee from time to time, all in accordance with the Corporation's 
Certificate of Incorporation and Amended and Restated Bylaws, and with 
applicable law. No member of the Board or of the Committee shall be liable 
for any action or determination made in good faith with respect to the Plan 
or any Option granted or Option Agreement entered into hereunder.

3.       COMMON STOCK

         The stock that may be issued pursuant to Options granted under the 
Plan shall be shares of common stock, par value $0.001 per share, of the 
Corporation ("Common Stock"), which shares may be treasury shares or 
authorized but unissued shares. The number of shares of Common Stock that may 
be issued pursuant to Options granted under the Plan shall not exceed in the 
aggregate 250,000 shares, which number of shares is subject to adjustment as 
hereinafter provided in Section 12 below.





1998 EMPLOYEE STOCK OPTION PLAN                                         PAGE 1





4.       EFFECTIVE DATE AND TERM OF THE PLAN

         The Plan shall be effective as of the date on which the merger
described in that certain Agreement and Plan of Merger dated as of April 15,
1998, by and among the Corporation, SMSI Acquisition Company, Signal Medical
Services, Inc.. and its stockholders becomes effective ("Effective Date") and
shall continue in effect for a term of ten (10) years. Any Options outstanding
under the Plan on such date shall continue to be exercisable pursuant to their
terms, except as otherwise provided herein.

5.       GRANT OF OPTIONS

         Subject to the terms and conditions of the Plan, each Optionee is
hereby granted as of the Effective Date, Options to purchase such number of
shares of the Common Stock listed on Attachment 1 hereto at a purchase price of
$ _____ per share, on the terms and conditions set forth in the written
agreements ("Option Agreements"), to be executed by the Corporation and by the
Optionee, in the form of Attachment 2 hereto.

6.       TERM AND EXERCISE OF OPTIONS

         (a) Method of Exercise and Payment. An Option that is exercisable 
hereunder may be exercised by delivery to the Corporation on any business 
day, at its principal office, addressed to the attention of the Corporate 
Secretary, of written notice of exercise in the form attached to the Option 
Agreement as Exhibit A, which notice shall specify the number of shares with 
respect to which the Option is being exercised, and shall be accompanied by 
payment in full of the Option Price of the shares for which the Option is 
being exercised. The minimum number of shares of Common Stock with respect to 
which an Option may be exercised, in whole or in part, at any time shall be 
the lesser of 100 shares or the maximum number of shares available for 
purchase under the Option at the time of exercise. Payment of the Option 
Price for the shares of Common Stock purchased pursuant to the exercise of an 
Option shall be made (i) in cash or in cash equivalents; (ii) with the 
consent of the Committee, through the tender to the Corporation of shares of 
Common Stock, which shares shall be valued, for purposes of determining the 
extent to which the Option Price has been paid thereby, at their Fair Market 
Value (as defined below) on the date of exercise; or (iii) by a combination 
of the methods described in (i) and (ii). If shares of Common Stock are 
surrendered by an officer of the Corporation (as the term "officer" is 
defined in Section 10(c) below) for payment and the Common Stock surrendered 
was acquired pursuant to an Option of the Corporation, then six (6) months 
must have elapsed since the date of grant of such Option. The payment in full 
of the Option Price need not accompany the written notice of exercise 
provided the notice of exercise directs that the Common Stock certificate or 
certificates for the shares for which the Option is exercised be delivered to 
a licensed broker acceptable to the Corporation as the agent for the 
individual exercising the Option and, at the time such Common Stock 
certificate or certificates are delivered, the broker shall tender to the 
Corporation cash (or cash equivalents acceptable to the Corporation) equal to 
the Option Price for the shares of Common Stock purchased pursuant to the 
exercise of the Option plus the amount (if any) of federal and/or other taxes 
which the Corporation, may, in its judgment, be required to withhold with 
respect to the exercise of the Option. Any attempt to exercise any Option 
granted hereunder other than as set forth above shall be invalid and of no 
force and effect. Promptly after the exercise of an Option and the payment in 
full of the Option Price of the shares of Common Stock covered thereby, the 
individual exercising the Option shall be entitled to the issuance of a 
Common Stock certificate or certificates evidencing his ownership of such 
shares. An individual holding or exercising an Option shall have none of the 
rights of a stockholder until the shares of Common Stock covered thereby are 
fully paid and issued to him, and except as provided in Section 12 below, no 
adjustment shall be made for dividends or other rights for which the record 
date is prior to the date of such issuance.

         (b) Fair Market Value. "Fair Market Value" means the value of each 
share of Common Stock subject to the Plan determined as follows: If on the 
date of exercise the Common Stock is listed on an 


1998 EMPLOYEE STOCK OPTION PLAN                                         PAGE 2







established national or regional stock exchange, is admitted to quotation on 
The Nasdaq Stock Market, or is publicly traded on an established securities 
market, the Fair Market Value of the Common Stock shall be the closing price 
of the Common Stock on such exchange or in such market (the highest such 
closing price if there is more than one such exchange or market) on the date 
of exercise or on the trading day immediately preceding the date of exercise 
if the date of exercise is not a trading day (or, if there is no such 
reported closing price, the Fair Market Value shall be the mean between the 
highest bid and lowest asked prices or between the high and low sale prices 
on such trading day), or, if no sale of the Common Stock is reported for such 
trading day, on the next preceding day on which any sale shall have been 
reported. If the Common Stock is not listed on such an exchange, quoted on 
such Stock Market or traded on such a market, Fair Market Value shall be 
determined by the Committee in good faith.

         (c) Withholding. The Corporation shall have the right to withhold, 
or require an Optionee to remit to the Corporation, an amount sufficient to 
satisfy any applicable federal, state, local or foreign withholding tax 
requirements imposed with respect to the exercise of Options. Subject to the 
consent of the Committee which may be withheld in its sole and absolute 
discretion, and to the extent permissible under applicable tax, securities, 
and other laws, an Optionee may (a) have shares of Common Stock otherwise 
issuable to the Optionee hereunder withheld, or (b) tender to the Corporation 
previously acquired shares of Common Stock, having a Fair Market Value 
sufficient to satisfy all or part of the Optionee's federal, state and local 
tax obligations associated with the exercise of Options.

7.       TRANSFERABILITY OF OPTIONS

         During the lifetime of an Optionee to whom an Option is granted, 
only such Optionee (or, in the event of legal incapacity or incompetency, the 
Optionee's guardian or legal representative) may exercise the Option. No 
Option shall be assignable or transferable by the Optionee to whom it is 
granted, other than by will, the laws of descent and distribution, or 
pursuant to a qualified domestic relations order as defined in section 414 of 
the Code, or such other transfers as may be permitted by the Committee and no 
Option shall be pledged or hypothecated (by operation of law or otherwise), 
or subject to execution, attachment or similar process.

8.       TERMINATION OF EMPLOYMENT

         Upon the termination of the employment of an Optionee with the 
Corporation or a subsidiary of the Corporation, other than by reason of the 
death or "permanent and total disability" (within the meaning of section 
22(e)(3) of the Code) of such Optionee, any Option granted to an Optionee 
pursuant to the Plan shall terminate thirty (30) days after the date of such 
termination of employment, unless otherwise provided pursuant to the Option 
Agreement. A leave of absence or leave on military or government service 
approved by the Committee shall not constitute a termination of employment 
for purposes of the Plan. For purposes of the Plan, a termination of 
employment with the Corporation or a subsidiary of the Corporation shall not 
be deemed to occur if the Optionee is immediately thereafter employed with 
the Corporation or any subsidiary of the Corporation.

9.       USE OF PROCEEDS

         The proceeds received by the Corporation from the sale of Common 
Stock pursuant to Options granted under the Plan shall constitute general 
funds of the Corporation.

10.      REQUIREMENTS OF LAW

         (a) Violations of Law. The Corporation shall not be required to sell 
or issue any shares of Common Stock under any Option if the sale or issuance 
of such shares would constitute a violation by the individual exercising the 
Option or the Corporation of any provisions of any law or regulation of any



1998 EMPLOYEE STOCK OPTION PLAN                                         PAGE 3





governmental authority, including without limitation any federal or state 
securities laws or regulations. Specifically in connection with the 
Securities Act of 1933, as amended ("1933 Act"), upon exercise of any Option, 
unless a registration statement under the 1933 Act is in effect with respect 
to the shares of Common Stock covered by such Option, the Corporation shall 
not be required to sell or issue such shares unless the Committee has 
received evidence satisfactory to it that the holder of such Option may 
acquire such shares pursuant to an exemption from registration under the 1933 
Act. Any determination in this connection by the Committee shall be final, 
binding and conclusive. The Corporation may, but shall in no event be 
obligated to, register any securities covered hereby pursuant to the 1933 
Act. The Corporation shall not be obligated to take any affirmative action in 
order to cause the exercise of an Option or the issuance of shares of Common 
Stock pursuant thereto to comply with any law or regulation of any 
governmental authority, except the Corporation shall timely file for 
registration, on Form S-8 under the 1933 Act, of the shares of Common Stock 
to be issued upon exercise of the Options granted under the Plan. As to any 
jurisdiction that expressly imposes the requirement that an Option shall not 
be exercisable unless and until the shares of Common Stock covered by such 
Option are registered or are subject to an available exemption from 
registration, the exercise of such Option (under circumstances in which the 
laws of such jurisdiction apply) shall be deemed conditioned upon the 
effectiveness of such registration or the availability of such an exemption.

         (b) Compliance with Rule 16b-3. The Plan is intended to comply with 
Rule 16b-3 or its successor rule., promulgated under the Securities Exchange 
Act of 1934 ("1934 Act"). With respect to persons subject to Section 16 of 
the 1934 Act, any provision of the Plan or action of the Committee that is 
inconsistent with such Rule shall be deemed null and void to the extent 
permitted by law and deemed advisable by the Committee.

         (c) Holding Period for Officers. With respect to Options granted to 
officers of the Corporation (as the term "officer" is defined in the rules 
promulgated under Section 16 of the 1934 Act) and except as may be approved 
by the Committee, at least six (6) months must elapse from the date of grant 
of the Option and (i) any disposition of the Option (not including its 
exercise), or (ii) any disposition of the underlying Common Stock.

11.      AMENDMENT AND TERMINATION OF THE PLAN

         The Board may, at any time and from time to time, amend, suspend or 
terminate the Plan; provided however, that no amendment, suspension or 
termination of the Plan by the Board may, without the consent of the holder 
of the Option, adversely affect any rights or obligations under any Option 
theretofore granted under the Plan.





1998 EMPLOYEE STOCK OPTION PLAN                                         PAGE 4






12.      EFFECT OF CHANGES IN CAPITALIZATION

         (a) Changes in Common Stock. If the outstanding shares of Common 
Stock are increased or decreased or changed into or exchanged for a different 
number or kind of shares or other securities of the Corporation by reason of 
any recapitalization, reclassification, stock split-up, combination of 
shares, exchange of shares, stock dividend or other distribution payable in 
capital stock, or other increase or decrease affecting such outstanding 
shares generally that is effected without receipt of consideration by the 
Corporation, occurring after the Effective Date, the number and kinds of 
shares for the purchase of which Options may be granted under the Plan shall 
be adjusted proportionately and accordingly by the Committee. In addition, 
the number and kind of shares for which Options are outstanding shall be 
adjusted proportionately and accordingly so that the proportionate ownership 
interest of the holder of the Option immediately following such event shall, 
to the extent practicable, be the same as immediately prior to such event. 
Any such adjustment in outstanding Options shall not change the aggregate 
Option Price payable with respect to shares subject to the unexercised 
portion of the Option outstanding but shall include a corresponding 
proportionate adjustment in the Option Price per share. If there is a 
distribution payable in the capital stock of a subsidiary corporation of the 
Corporation ("Spin-off Shares"), to the extent consistent with Treasury 
Regulation section 1.425-1(a)(6) or the corresponding provision of any 
subsequent regulation, each outstanding Option shall thereafter additionally 
pertain to the number of Spin-off Shares that would have been received in 
such distribution by a stockholder of the Corporation who owned a number of 
shares of Common Stock equal to the number of shares that are subject to the 
Option at the time of such distribution, and the aggregate Option Price of 
the Option shall be allocated between the Spin-off Shares and the Common 
Stock in proportion to the relative Fair Market Values of a Spin-off Share 
and a share of Common Stock immediately after the distribution of Spin-off 
Shares.

         (b) Reorganization in Which the Corporation Is the Surviving 
Corporation. If the Corporation shall be the surviving corporation in any 
reorganization, merger, or consolidation of the Corporation with one or more 
other corporations, any Option theretofore granted pursuant to the Plan shall 
pertain to and apply to the securities to which a holder of the number of 
shares of Common Stock subject to such Option would have been entitled 
immediately following such reorganization, merger, or consolidation, with a 
corresponding proportionate adjustment of the Option Price per share so that 
the aggregate Option Price thereafter shall be the same as the aggregate 
Option Price of the shares remaining subject to the Option immediately prior 
to such reorganization, merger, or consolidation.

         (c) Reorganization in Which the Corporation Is Not the Surviving 
Corporation; Sale of Assets or Stock. Upon the dissolution or liquidation of 
the Corporation, or upon a merger, consolidation or reorganization of the 
Corporation with one or more other corporations in which the Corporation is 
not the surviving corporation, or upon a sale of substantially all of the 
assets of the Corporation to another corporation, or upon any transaction 
(including, without limitation, a merger or reorganization in which the 
Corporation is the surviving corporation) approved by the Board which results 
in any person or entity owning eighty percent or more of the combined voting 
power of all classes of stock of the Corporation, the Plan and all Options 
outstanding hereunder shall terminate, except to the extent provision is made 
in writing in connection with such transaction for the continuation of the 
Plan and/or the assumption of the Options theretofore granted, or for the 
substitution for such Options of new options covering the stock of a 
successor corporation, or a parent or subsidiary thereof, with appropriate 
adjustments as to the number and kinds of shares and exercise prices, to 
preserve the then excess, if any, of the aggregate Fair Market Value of the 
shares subject to Options over the purchase price for the shares under the 
Options, in which event the Plan and Options theretofore granted shall 
continue in the manner and under the terms so provided. In the event of any 
such termination of the Plan, each individual holding an Option shall have 
the right, immediately prior to the occurrence of such termination and during 
such period occurring prior to such termination as the Board in its sole 
discretion shall determine and designate, to exercise such Option in whole or 
in part, whether or not such Option was otherwise exercisable at the time 
such termination occurs 


1998 EMPLOYEE STOCK OPTION PLAN                                         PAGE 5




and without regard to any installment limitation on exercise imposed pursuant 
to the Option Agreement. The Board shall send written notice of an event that 
will result in such a termination to all individuals who hold Options not 
later than the time at which the Corporation gives notice thereof to its 
stockholders. Notwithstanding the foregoing, the occurrence of any event 
described in this Section 12(c) which also constitutes a Change of Control 
(as defined below) shall cause the exercisability in full of all Options 
whether or not (i) all conditions to exercise have been satisfied and (ii) 
the Plan is terminated pursuant to this Section 12(c).

         (d) Adjustments. Adjustments under this Section 12 related to stock 
or securities of the Corporation shall be made by the Board, whose 
determination in that respect shall be final, binding and conclusive. No 
fractional shares of Common Stock or units of other securities shall be 
issued pursuant to any such adjustment, and any fractions resulting from any 
such adjustment shall be eliminated in each case by rounding downward to the 
nearest whole share or unit.

         (e) No Limitations on the Corporation. The grant of an Option 
pursuant to the Plan shall not affect or limit in any way the right or power 
of the Corporation to make adjustments, reclassifications, reorganizations or 
changes of its capital or business structure or to merge, consolidate, 
dissolve or liquidate, or to sell or transfer all or any part of its business 
or assets.

13.      CHANGE OF CONTROL

         "Change of Control" means the Corporation or its stockholders enter 
into an agreement or agreements, in one or a series of related transactions, 
to dispose of, whether by sale, exchange, merger, consolidation, 
reorganization, recapitalization, dissolution or liquidation (a) not less 
than 80% of the assets of the Corporation or (b) a portion of the outstanding 
Common Stock such that after the transaction or transactions one person or 
"group" (as defined by the Securities and Exchange Commission) owns, of 
record or beneficially, 50% or more of the outstanding capital stock of the 
Corporation, or the right (by whatever means) or the voting power to elect 
50% or more of the directors of the Corporation.

14.      DISCLAIMER OF RIGHTS

         No provision in the Plan or in any Option granted or Option 
Agreement entered into pursuant to the Plan shall be construed to confer upon 
any individual the right to remain in the employ of the Corporation or any 
subsidiary of the Corporation, or to interfere in any way with the right and 
authority of the Corporation or any subsidiary of the Corporation either to 
increase or decrease the compensation of any individual at any time, or to 
terminate any employment or other relationship between any individual and the 
Corporation or any subsidiary of the Corporation.

15.      NONEXCLUSIVITY OF THE PLAN

         The adoption of the Plan shall not be construed as creating any 
limitations upon the right and authority of the Board to adopt such other 
incentive compensation arrangements (which arrangements may be applicable 
either generally to a class or classes of individuals or specifically to a 
particular individual or individuals) as the Board in its discretion 
determines desirable, including, without limitation, the granting of stock 
options otherwise than under the Plan.

16.      GOVERNING LAW

         THE VALIDITY, INTERPRETATION AND EFFECT OF THE PLAN, AND THE RIGHTS 
OF ALL PERSONS HEREUNDER, SHALL BE GOVERNED BY AND DETERMINED IN ACCORDANCE 
WITH THE LAWS OF DELAWARE, OTHER THAN THE CHOICE OF LAW RULES THEREOF.
