                                       PART III

ITEM 10.       DIRECTORS AND EXECUTIVE OFFICERS OF THE REGISTRANT

THE BOARD OF DIRECTORS FOLLOWING THE RECAPITALIZATION
               
Pursuant to the terms of the Recapitalization (see "Item 1, Business 
--Recapitalization" in the Form 10-K), the number of directors comprising the 
Company's Board of Directors ("Board") is fixed at nine.  Six directors 
("Common Stock Directors") are to be elected by the Common Stock holders, one 
of whom ("Joint Director") is to be proposed by the holders of a majority of 
each of the Series B Preferred Stock and the Series C Preferred Stock and 
approved by a majority of the Board in its sole discretion.  Of the three 
remaining directors ("Preferred Stock Directors"), two are to be elected by 
the holders of the Series B Preferred Stock ("Series B Directors") and one is 
to be elected by the holders of the Series C Preferred Stock ("Series C 
Director"), in each case acting by written consent and without a meeting of 
the Common Stock holders.  As long as the initial purchasers of the Series B 
Preferred Stock and their affiliates ("Carlyle Stockholders") own at least 
50% of the Series B Preferred Stock, the holders of the Series B Preferred 
Stock will have the right to elect two Preferred Stock Directors and as long 
as the Carlyle Stockholders own at least 25% but less than 50% of such stock, 
such holders will have the right to elect one Preferred Stock Director.  As 
long as GE owns at least 25% of the Series C Preferred Stock, the holders of 
the Series C Preferred Stock will have the right to elect one Preferred Stock 
Director.   Except in the event of a conversion of all of the Series B 
Preferred Stock and Series C Preferred Stock into Series D Preferred Stock 
(see "Possible Future Board Changes" below), if the ownership percentage of 
the Carlyle Stockholders or GE falls below the applicable threshold, the 
Preferred Stock Director(s) formerly entitled to be elected by the Series B 
Preferred Stock holders or the Series C Preferred Stock holders, as 
applicable, will automatically be removed and the Board will be able to fill 
the resulting vacancies for the balance of the terms of such directors. 
Thereafter, such directors will be elected by the Common Stock holders.  
Holders of the Series B Preferred Stock and Series C Preferred Stock are not 
entitled to participate in the election of the Common Stock Directors.  Such 
holders are otherwise entitled to vote as a single class with the Common 
Stock on an as-if-converted basis, provided that the maximum aggregate voting 
percentage in such event may not exceed 37% of the shares eligible to vote. 
Carlyle owns approximately 33% of the voting power of the Common Stock 
assuming the conversion of the Series B Preferred Stock and the Series C 
Preferred Stock (approximately 35% assuming exercise of the Carlyle 
Warrants).  GE will own approximately 37% of the voting power of the Common 
Stock assuming the conversion of the Series B Preferred Stock and the Series 
C Preferred Stock and assuming the Second Closing occurs (approximately 39% 
assuming exercise of the GE Warrants).  Presently, the Board consists of 
seven directors, five of whom are Common Stock Directors and two of whom are 
Series B Directors.   GE intends to elect its Preferred Stock Director as of 
the Second Closing.  The vacancy created for the Joint Director has not yet 
been filled.

The Company's Certificate of Incorporation provides that the Common Stock
Directors serve for three-year terms which are staggered to provide for the
election of approximately one-third of the Board members each year.  The term of
the Class I directors (which will include the Joint Director) expires at the
next annual stockholders' meeting, the term of the Class II directors expires at
the 1998 annual meeting and the term of the Class III directors expires at the
1999 annual meeting.  The terms of the two Series B Directors will coincide with
the terms of the Class I and Class III directors, respectively, and the term of
the Series C Director will coincide with the term of the Class II directors.

(1) Potential realizable value is determined by taking the exercise price per
share and applying the stated annual appreciation rate compounded annually for
the remaining term of the option (ten years), subtracting the exercise price per
share at the end of the period and multiplying the remaining number by the
number of options granted.  Actual gains, if any, on stock option exercises and
InSight Common Stock holdings are dependant on the future performance of InSight
Common Stock and overall stock market conditions.

on NASDAQ Small Cap Market for InSight Common Stock).

(3) Options granted in fiscal 1997 are exercisable starting twelve (12) months

INDEMNIFICATION AGREEMENTS 

The Company has entered into separate indemnification agreements with each of
its directors and officers that could require the Company, among other things,
to indemnify them against certain liabilities that may arise by reason of their
status or service as directors and officers and to advance expenses incurred by
them as a result of any proceedings against them as to which they could be
indemnified. 

The Recapitalization agreements also contain provisions for the indemnification
of the Company's directors under certain circumstances.  The agreements pursuant
to which the Carlyle Stockholders and GE acquired Series B Preferred Stock and
Series C Preferred Stock, respectively, provide that the Company will indemnify,
defend and hold harmless the Carlyle Stockholders and GE, as the case may be,
and their respective affiliates, directors, officers, advisors, employees and
agents to the fullest extent lawful from and against all demands, losses,
damages, penalties, claims, liabilities, obligations, actions, causes of action
and reasonable expenses ("Losses') arising out of the agreements or the related
transactions or arising by reason of or resulting from the breach of any
representation, warranty, covenant or agreement of the Company contained in such
agreements for the period for which such representation or warranty survives;
provided, however, that the Company does not have any liability to indemnify the
Carlyle Stockholders or GE with respect to Losses arising from the bad faith or
gross negligence of the Carlyle or GE indemnified party.  The Recapitalization
agreements provide that no claim may be made by the Carlyle Stockholders or GE
against the Company for indemnification until the aggregate dollar amount of all
Losses incurred by the Carlyle Stockholders or GE, as applicable, exceeds
$250,000 and the indemnification obligations of the Company shall be effective
only until the dollar amount paid in respect of the Losses incurred by the
Carlyle Stockholders or GE, as applicable, and indemnified against aggregates to
an amount equal to $25 million, except with respect to Losses resulting from the
breaches of certain representations or covenants, which are unlimited in amount.

EMPLOYMENT AGREEMENTS AND SEVERANCE ARRANGEMENTS 

The Company has entered into executive employment agreements with its chief
executive officer, the Other Executive Officers and Messrs. Cragin, Drazba and
Henderson and Ms. MacFarlane, which provide for rolling twelve (12) month
periods of employment, and severance compensation equal to 12 months of
compensation at his or her annual salary rate then in effect, in the event the
executive's employment is terminated (i) because of physical or mental
disability, (ii) because of discretionary action of the Board of InSight, or
(iii) voluntarily by the executive due to a "Change of Control." A "Change of
Control" will have occurred if (a) the Company or its stockholders enter into an
agreement to dispose of, whether by sale, exchange, merger, consolidation,
reorganization, dissolution or liquidation, (i) not less than 80% of the assets
of the Company or (ii) a portion of the outstanding InSight Common Stock such
that one person or "group" (as defined by the SEC) owns, of record or
beneficially, not less than 50% of the outstanding InSight Common Stock; or (b)
one person or "group" (as defined by the SEC) acquires not less than 18% of the
Post-Conversion Common Stock (as defined below). However, a Change of Control
will not have occurred if GE converts its Series A Preferred Stock into
InSight Common Stock. "Post-Conversion Common Stock" means the outstanding
InSight Common Stock issuable, at the time a determination is made, upon
conversion of the outstanding Series A Preferred Stock. In the event that the
executive's employment is terminated for cause, he or she has no right to
receive any severance compensation under his or her employment agreement. In
consideration for such severance compensation, each executive has agreed not to
solicit, entice, divert or otherwise contact any customer or employee of InSight
for any provision of services which constitute "Company Business" during the
period that the executive is receiving severance compensation or for a period of
12 months after the executive's termination of employment, whichever is later.
"Company Business" means the development and operation, at times together with
other healthcare providers, of outpatient facilities which provide diagnostic
services in the areas of general radiology, MRI, cardiology and neurosciences
utilizing the related equipment and computer programs and software and various
distribution methods and investment structures.

Mr. Egger, a director and chairman of the board, has entered into a consulting
agreement with InSight providing for compensation at the rate of $100,000 per
year.  Mr. Egger's agreement provides for severance compensation equal to 12
months of compensation in the event the agreement is terminated as a result of
(i) Mr. Egger becoming physically or mentally disabled, (ii) discretionary
action of the Board of InSight, or (iii) a corporate reorganization that has the
effect of diminishing or impairing Mr. Egger's consulting responsibilities.

Preferred Stock and Series C Preferred Stock within the meaning of Rule

three Preferred Stock Directors, two of whom (the "Series B Directors") are 
to be elected by the 

                                          14
<PAGE>

Series B Preferred Stock holders and one of whom (the "Series C Director") is 
to be elected by the Series C Preferred Stock holders.  There are currently 
seven directors, including five Common Stock Directors and two Series B 
Directors.  GE intends to fill the Series C Director vacancy as of the date 
of the Second Closing.  The Joint Director vacancy has not yet been filled.  
Thus, the Common Stock holders currently are entitled to elect a majority of 
the Board.

Under certain circumstances, the holders of the Series D Preferred Stock 
(which is issuable only on conversion of the Series B Preferred Stock and the 
Series C Preferred Stock) would be entitled to elect a majority of the Board. 
If, at any time on or after the first anniversary of the initial funding 
under the Bank Financing (which occurred on October 22, 1997) ("Trigger 
Date"), a majority of the holders of each of the Series B Preferred Stock and 
the Series C Preferred Stock elect to convert such stock into Series D 
Preferred Stock, then all shares of Series B Preferred Stock and Series C 
Preferred Stock will automatically be converted into shares of Series D 
Preferred Stock on the date of such election ("Conversion Date").   
Immediately following such conversion, the number of members of the Board 
will be increased by the smallest number of directors ("Conversion 
Directors") such that the percentage of the total Board represented by the 
Conversion Directors and the Preferred Stock Directors ("Series D Directors") 
would correspond to the percentage of Common Stock owned by the Series D 
Preferred Stock holders on an as-if-converted basis, provided that the Series 
D Directors shall constitute less than two-thirds of the Board.  In such 
event, the Preferred Stock Directors would remain on the Board and the 
vacancies created for the Conversion Directors would be filled by the Series 
D Preferred Stock holders.  The percentage of the outstanding Common Stock 
currently owned by the Series B Preferred Stock holders, assuming conversion 
of all of the outstanding Series B Preferred Stock and Series C Preferred 
Stock, is approximately 33% and the percentage of the outstanding Common Stock 
currently owned by the Series C Preferred Stock holders, assuming conversion 
of all of the outstanding Series B Preferred Stock and Series C Preferred 
Stock, is approximately 37%. If such Preferred Stock were converted into 
Series D Preferred Stock on or after the Trigger Date, the aggregate 
percentage of Common Stock owned by the Series D Preferred Stock holders 
would be approximately 70%.   Thus, as a result of such conversion, designees 
of the Series D Preferred Stock holders would  constitute a majority (but 
less than two-thirds) of the Board.

The holders of Series D Preferred Stock will have the right to vote with the 
holders of Common Stock with respect to all matters submitted to a 
stockholder vote except, until the second annual meeting of stockholders 
after the Conversion Date, for the election of directors.  At and after the 
second annual stockholders meeting, the positions of all directors whose 
terms have expired will be subject to election by holders of Common Stock and 
Series D Preferred Stock voting together as a class, with each share of 
Series D Preferred Stock having the number of votes equal to the number of 
shares of Common Stock into which such share is then convertible.  
Notwithstanding the foregoing, if the Conversion Date is prior to October 14, 
1999, then from the Conversion Date until the second subsequent annual 
stockholders meeting, except as provided in the next sentence, none of the 
following transactions may be effected by the Company, and neither the 
Carlyle Stockholders, GE, nor any other holder of Series D Preferred Stock 
shall participate in such transactions, if any transferee of the Carlyle 
Stockholders or GE or any other person referred to in the following clauses 
beneficially owns five percent (5%) or more of the Company's voting shares: 
(i) any merger or consolidation of the Company or any of its subsidiaries 
with or into such person; (ii) any sale, lease, exchange or other disposition 
of all or any substantial part of the assets of the Company or any of its 
subsidiaries to such other person; (iii) the issuance or delivery of any 
voting securities of the Company or any of its subsidiaries to such other 
person in exchange for cash, other assets or securities, or a combination 
thereof; or (iv) any dissolution or liquidation of the Company.  The 
foregoing prohibition shall not apply with respect to a transaction approved 
by (i) at least 80% of the Company's outstanding voting shares (which 
includes the Common Stock and the Series D Preferred Stock) or (ii) at least 
two-thirds of the Company's directors (which must include, to the extent 
still a director, either (A) the Joint Director, if such Joint Director 
served in such position as of the Conversion Date or has been approved by a 
majority of the directors who were Common Stock Directors as of the 
Conversion Date, or (B) at least one director who was a Common Stock Director 
prior to the Conversion Date).

ITEM 13.       CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS 

TRANSACTIONS WITH THE ESTATE OF CAL KOVENS 

In February 1992, AHS purchased a Gamma Knife from Elekta to be located in 
California and made a deposit toward the  purchase of another Gamma Knife.  
AHS received nonrecourse interim financing of $2,000,000 toward the 
acquisition of the Gamma Knife and the deposit for the other Gamma Knife from 
Cal Kovens (a director until his death on February 6, 1995).  The interim 
financing was borrowed from Mr. Kovens pursuant to the terms of a nonrecourse 
promissory note secured by the Gamma Knife and due August 24, 1992, at an 
interest rate of 10.5% per annum.  Mr. Kovens extended the term of the note 
while AHS sought to obtain permanent financing. 

                                          15
<PAGE>

In December 1992, AHS's wholly owned subsidiary, Radiosurgery Centers, Inc. 
("RCI"), entered into a five-year loan of $2,750,000 with City National Bank 
of Florida ("City National Bank"), and the promissory note in favor of Mr. 
Kovens was repaid from the proceeds of such loan in the first quarter of 
1993. The new loan was guaranteed by Mr. Kovens and his spouse, Roz Kovens. 
During the second half of fiscal 1993, Mr. Kovens repurchased RCI's 
promissory note from City National Bank. Pursuant thereto, Mr. Kovens was 
paid approximately $195,000 in interest in fiscal 1993. 

In early 1993, RCI, AHS and Elekta became involved in a dispute when RCI 
advised Elekta that it intended to relocate the Gamma Knife it purchased for 
a location in California to Miami, Florida, since in December 1992, RCI had 
entered into an agreement with Public Health Trust, an agency and 
instrumentality of Metropolitan Dade County, Florida, to establish and 
operate a Gamma Knife center at Jackson Memorial Hospital Medical Center 
located in Miami. The parties settled their claims and, pursuant to the terms 
thereof, Mr. Kovens agreed to guarantee certain scheduled payments of 
$250,000 to be made by RCI to Elekta in connection with the delivery of the 
Gamma Knife to Miami, which payment has been made by RCI. 

In February 1994, RCI entered into a new five-year loan of $2,900,000 with 
County National Bank of South Florida.  Mr. Kovens was repaid from the 
proceeds of such new bank loan in the first quarter of 1994.  This loan was 
guaranteed by Mr. Kovens and secured by certain real property owned by Mr. 
Kovens.  Effective March 1, 1996, RCI refinanced the remainder of the 
equipment loan (approximately $2,075,000) with GE on terms substantially 
equivalent to the original equipment loan.  The loan is secured by all of the 
assets of the Gamma Knife center. The loan was also secured by a letter of 
credit of $400,000 which was guaranteed by the estate of Cal Kovens until 
September 30, 1997.  On February 4, 1997, GE permitted the estate of Cal 
Kovens to substitute securities in exchange for the letter of credit.


In November 1994, AHS issued Mr. Kovens a warrant to purchase 200,000 shares 
of AHS Common Stock at $0.25 per share in consideration of the Gamma Knife 
financing activities discussed above.  Pursuant to the terms of the Merger, 
InSight assumed the warrant which, after the applicable exchange ratio, 
became a warrant to purchase 20,000 shares of InSight Common Stock at the 
exercise price of $2.50 per share.  The warrant is exercisable at any time up 
to November 14, 1997. 

TRANSACTIONS WITH FRANK E. EGGER 


Since July 1, 1996, Mr. Egger has been paid $100,000 per year for acquisition 
and financing activities pursuant to a consulting agreement.  In the event 
the agreement is terminated as a result of (i) Mr. Egger becoming physically 
or mentally disabled, (ii) discretionary action of the Board of InSight, or 
(iii) a corporate reorganization that has the effect of diminishing or 
impairing Mr. Egger's consulting responsibilities, he is entitled to a 
severance compensation equal to 12 months of compensation. 

Pursuant to certain agreements among InSight, AHS and the holders of AHS 
Series B Preferred Stock, InSight issued to Mr. Egger on August 9, 1996 a 
warrant to purchase 2,268 shares of InSight Common Stock at the exercise 
price of $5.64 per share.  The warrant is exercisable at any time up to 
August 9, 2001. In addition, subject to certain conditions, Mr. Egger, and 
other holders, have certain "piggyback" registration rights to register the 
shares subject to the warrants under the Securities Act. See "Transactions 
with Holders of AHS Series B Preferred Stock." 

TRANSACTIONS WITH GE

GE, as the primary creditor of AHS and Maxum, had from time to time granted 
AHS and Maxum certain financial accommodations with respect to certain loans 
and leases.  In exchange for such accommodations, AHS and Maxum issued 
certain considerations to GE.  As a prerequisite to the consummation of the 
Merger, certain financial accommodations were provided by GE, the primary 
creditor of each of AHS and Maxum, and its affiliates.  As a result, certain 
debt and operating lease obligations of AHS and Maxum were reduced in 
exchange for, among other things, the issuance to GE immediately prior to the 
consummation of the Merger of AHS Series C Preferred Stock and Maxum Series B 
Preferred Stock. At the effective time of the Merger, the AHS Series C 
Preferred Stock and Maxum Series B Preferred Stock issued to GE was converted 
into the right to receive such number of shares of InSight Series A Preferred 
Stock which were convertible into InSight Common Stock representing 
approximately 48% of InSight Common Stock outstanding at the effective time 
of the Merger (after giving effect to such conversion). 

                                          16
<PAGE>

In addition, as part of the granting of certain financial accommodations
contemplated to be provided by GE, at the effective time of the Merger, warrants
previously issued to GE by AHS to acquire 1,589,072 shares of AHS Common Stock,
and warrants previously issued to GE by Maxum to acquire 700,000 shares of Maxum
Common Stock, were canceled. Furthermore, GE had the right to receive for ten
years annual payments ("Supplemental Service Fee") under its maintenance
agreements with InSight, AHS and Maxum equal to 14% of InSight pre-tax income,
subject to certain adjustments, and further subject to proportional reductions
for certain post-Merger acquisitions. InSight terminated the Supplemental
Service Fee on October 14, 1997 as part of the Recapitalization in exchange for
the issuance to GE of 7,000 shares of Series C Preferred Stock.

TRANSACTIONS WITH HOLDERS OF AHS SERIES B PREFERRED STOCK 

Pursuant to certain agreements among InSight, AHS and the holders of AHS Series
B Preferred Stock, the holders of Series B Preferred Stock agreed to waive any
rights to dividends, liquidation preferences, voting and redemption they might
have had in connection with the Merger and certain other rights. In
consideration therefor, upon the consummation of the Merger, InSight issued to
such holders, including Mr. Egger, Roz Kovens and the estate of Cal Kovens,
warrants to purchase an aggregate of 50,000 shares of InSight Common Stock at
the exercise price of $5.64 per share. The warrants are exercisable at any time
up to August 9, 2001. In addition, subject to certain conditions, the holders
have certain "piggy-back" registration rights to register the shares subject to
the warrants under the Securities Act. 

TRANSACTIONS WITH SHATTUCK HAMMOND PARTNERS 

On August 14, 1996, the Company entered into an agreement with Shattuck 
Hammond Partners, Inc. ("SHP"), an investment banking firm located in New 
York in which a director of the Company, Mr. Chamberlain, is a vice 
president, pursuant to which SHP will provide general strategic advisory and 
investment banking services. The term of the agreement commenced July 1, 1996 
and extends through December 31, 1997. The Company is obligated to pay SHP 
$180,000, payable in quarterly installments of $30,000. SHP is also entitled 
to separately negotiated fees for certain mergers or acquisitions. In 
connection with the Recapitalization, the Company has agreed to pay SHP a fee 
of $500,000 for providing certain advisory services. In addition, the Company 
also issued SHP a warrant to purchase 35,000 shares of InSight Common Stock 
at an exercise price of $5.50 per share. The warrant vests cumulatively on a 
monthly basis over the 18 month term of the agreement. The warrant is 
exercisable at any time up to August 14, 2000. In addition, SHP has certain 
"piggy-back" registration rights to register the shares subject to the 
warrant under the Securities Act. 

FINANCIAL ADVISORY AND PLACEMENT FEES

In connection with the Recapitalization, the Company paid to each of the 
Carlyle Stockholders and GE a placement fee of $125,000, reimbursed the 
Carlyle Stockholders and GE an aggregate of $500,000 for reasonable 
out-of-pocket expenses incurred and agreed to pay each of the Carlyle 
Stockholders and GE an annual financial advisory fee equal to $50,000, 
payable quarterly, for a two-year period.
