ITEM 5.  OTHER EVENTS.

    On October 14, 1997, InSight Health Services Corp., a Delaware corporation
("InSight" or the "Company"), consummated a recapitalization
("Recapitalization") pursuant to which (a) certain investors (the "Carlyle
Stockholders")  affiliated with TC Group, L.L.C., a Delaware limited liability
company doing business as The Carlyle Group, a private merchant bank
headquartered in Washington, D.C., made a cash investment of $25 million in the
Company and received therefor 25,000 shares of newly issued Convertible
Preferred Stock, Series B of  the Company, par value $0.001 per share ("Series B
Preferred Stock"), initially convertible, at the option of the holders thereof,
in the aggregate into 2,985,075 shares of InSight common stock, par value $0.001
per share ("Common Stock"), and warrants (the "Carlyle Warrants") to purchase up
to 250,000 shares of Common Stock at the initial exercise price of $10.00 per
share; (b) General Electric Company, a New York corporation ("GE"), (i)
surrendered its rights under an amended equipment service agreement to receive
annual supplemental service fee payments equal to 14% of pretax income in
exchange for the issuance of 7,000 shares of newly issued Convertible Preferred
Stock, Series C of the Company, par value $0.001 per share ("Series C Preferred
Stock"), initially convertible, at the option of GE, in the aggregate into
835,821 shares of Common Stock, and warrants (the "GE Warrants") to purchase up
to 250,000 shares of Common Stock at the initial exercise price of $10.00 per
share, and (ii) agreed to exchange all of its shares of  InSight's Convertible
Preferred Stock, Series A of the Company, par value $0.001 per share (the
"Series A Preferred Stock"), on the business day (the "Second Closing") after
all waiting periods with respect to GE's filing under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, have expired or been terminated,
for an additional 20,953 shares of Series C Preferred Stock, initially
convertible, at the option of GE, in the aggregate into 2,501,851 shares of
Common Stock; and (c) the Company executed a Credit Agreement with NationsBank,
N.A. pursuant to which NationsBank, as agent and lender, committed to provide, a
total of $125 million in senior secured credit (the "Bank Financing"), including
(i) a $50 million term loan facility consisting of a $20 million tranche with
increasing amortization over a five-year period and a $30 million tranche with
increasing amortization over a seven-year period,  principally repayable in
years 6 and 7, (ii) a $25 million revolving working capital facility with a
five-year maturity, and (iii) a $50 million acquisition facility.

    Initial funding under the Bank Financing occurred on October 22, 1997 
and, on December 19, 1997, the acquisition facility was increased to $75 
million. The Second Closing occurred on November 4, 1997. As a result of the 
Second Closing, GE holds 27,953 shares of Series C Preferred Stock initially 
convertible, at its option, into 3,337,672 shares of Common Stock, and there 
are no shares of Series A Preferred Stock outstanding.

THE SERIES B PREFERRED STOCK

    The following is a description of the rights, preferences and privileges of
the Series B Preferred Stock as set forth in the Certificate of Designation,
Preferences and Rights of Convertible Preferred Stock, Series B (the "Series B
Certificate of Designation").  Such description does not purport to be complete
and is subject to and qualified in its entirety by reference to the Series B
Certificate of Designation, a copy of which is filed with the Securities and
Exchange Commission (the "SEC") as Exhibit 3.2 to InSight's Annual Report on
Form 10-K for the year ended June 30, 1997 (the "1997 Form 10-K").

    RANK.   The Series B Preferred Stock ranks, with respect to dividend 
distributions and distributions upon the liquidation, winding up and 
dissolution of the Company, (i) senior to all classes of the Company's Common 
Equity (defined to mean any class of common stock, including the Common 
Stock, which has the right, subject to preferred stock rights, to participate 
in any distribution of the assets or earnings of the Company without limit as 
to per share amount) and to each other class or series of the Company's 
capital stock ("Capital Stock"), the terms of which do not expressly provide 
that it ranks senior to or on a parity with the Series B Preferred Stock with 
respect to such distributions (collectively, the "Junior Securities"); (ii) 
on a parity with any class or series of Capital Stock which expressly 
provides that it ranks on a parity with the Series B Preferred Stock as to 
such distributions (such shares, together with the Series C Preferred Stock 
and the Convertible Preferred Stock, Series D, par value $0.001 (the "Series 
D Preferred Stock") are, collectively, the "Parity Securities"); and (iii) 
junior to each class or series of Capital Stock issued in accordance with the 
"Protective Provisions" described below and which expressly provides that it 
ranks senior to the Series B Preferred Stock as to such distributions 
(collectively, the "Senior Securities").

                                        - 2 -
<PAGE>

    DIVIDEND RIGHTS.  Each holder of Series B Preferred Stock is entitled to 
receive dividends (when, as and if declared by InSight's Board of Directors 
(the "Board"), together with holders of Series C Preferred Stock, Series D 
Preferred Stock (collectively with the Series B Preferred Stock, the 
"Preferred Stock") and Common Stock, on a basis proportionate to the number 
of shares of Common Stock held by such holder (assuming conversion of all 
Preferred Stock).  No dividends will be paid on any Common Stock until the 
holders of the Preferred Stock have been paid in full their pro rata portion 
thereof.

    LIQUIDATION PREFERENCE.  Upon any Liquidating Event (as defined below), the
holders of the Series B Preferred Stock then outstanding shall be entitled to be
paid $1,000 per share of Series B Preferred Stock (the "Series B Liquidation
Preference"), plus any declared but unpaid dividends thereon, before any payment
shall be made on any assets distributed to the holders of any of the Junior
Securities, including Common Stock.  Otherwise, holders of Series B Preferred
Stock shall not be entitled to any distribution in the event of liquidation,
dissolution or winding up of the affairs of the Company.  "Liquidating Event"
means, with respect to a Person (as defined below), any of (i) the commencement
by such Person of a voluntary case under the bankruptcy laws of the United
States or the commencement of an involuntary case against such Person with
respect to which the petition shall not be controverted within 15 days or
dismissed within 60 days after commencement thereof; (ii) the appointment of a
custodian for, or the taking charge by a custodian of, all or substantially all
of the property of such Person; (iii) the commencement by such Person of any
proceeding under any reorganization, arrangement, adjustment of debt, relief of
debtors, dissolution, insolvency or liquidation or similar law relating to such
Person; (iv) the commencement against such Person of any proceeding set forth in
clause (iii) which is not controverted within 10 days thereof and dismissed
within 60 days after commencement thereof; (v) the adjudication of such Person
insolvent or bankrupt, or the adoption by such Person of a plan of liquidation;
(vi) the occurrence of any Change of Control (as defined below) with respect to
such Person; or (vii) the filing of a certificate of dissolution in respect of
InSight; in any of cases (i) through (vi) above, in a single transaction or
series of related transactions.  "Person" means any individual, corporation,
partnership, joint venture, association, limited liability  company, joint-stock
company, trust, unincorporated organization or government or agency or political
subdivision thereof (including any subdivision or ongoing business of any such
entity or substantially all of the assets of any such entity, subdivision or
business).

    A "Change of Control" will be deemed to have occurred with respect to a
Person (i) at such  time as any person (as defined in Section 13(d)(3) of the
Securities Exchange Act of 1934, as amended) at any time shall directly or
indirectly acquire more than 40% in outstanding voting power of such Person,
(ii) at such time as during any one year period, individuals who at the
beginning of such period constitute such Person's board of directors or other
governing body cease to constitute at least a majority of such board or
governing body (other than upon a Type B Event Date (as defined below)), (iii)
upon consummation of a merger or consolidation of such Person into or with
another Person in which the stockholders of the subject Person immediately prior
to the consummation of such transaction shall own less than 50% of the voting
securities of the surviving Person (or its parent corporation where the
surviving Person is wholly owned by the parent corporation) immediately
following consummation of such transaction or (iv) the sale, transfer or lease
of all or substantially all of the assets of such Person, in any of cases of
(i), (ii), (iii) or (iv) above, in a single transaction or series of related
transactions; provided that no Change of Control shall be deemed to occur solely
by reason of (x) the ownership by the Carlyle Stockholders or any of their
affiliates or by GE or any of its affiliates of any Capital Stock of the
Company, (y) the conversion of Series C Preferred Stock into Series D Preferred
Stock (and any Board changes incident thereto) or (z) the conversion of Series D
Preferred Stock into Common Stock.

    CONVERSION RIGHTS.  Each share of Series B Preferred Stock is initially
convertible, without payment, by the holder thereof, into 119.403 shares of
Common Stock based upon an initial conversion price of $8.375 per share, subject
to adjustment (the "Conversion Price").  The Conversion Price is subject to (i)
decrease if InSight at any time subdivides (by stock split, stock dividend,
reclassification, recapitalization or otherwise) one or more classes or series
of its outstanding Common Equity into a greater number of shares or (ii)
increase if InSight at any


                                        - 3 -
<PAGE>

time combines (by reverse stock split or otherwise) one or more classes or
series of its outstanding Common Equity into a smaller number of shares.  In the
event of any Corporate Change (defined to mean any recapitalization,
reorganization, reclassification, consolidation, merger, sale of all or
substantially all of InSight's assets or other transaction, effected in such a
way that the holders of Common Equity are entitled to receive stock, securities,
cash, debt instruments or assets with respect to or in exchange for Common
Equity), each share of Series B Preferred Stock then outstanding will become
convertible only into the kind and amount of securities, cash and other property
receivable upon such Corporate Change by the holder of the number of shares of
Common Stock into which such share of Series B Preferred Stock was convertible
immediately prior thereto.  If InSight declares or pays a Liquidating Dividend
(defined to mean a dividend upon the Common Equity payable otherwise than out of
earnings or earned surplus except for a stock dividend payable in Common Stock),
InSight shall pay to each holder of a share of Series B Preferred Stock the
Liquidating Dividend that would have been paid to such holder on the Common
Stock such holder would have owned had such holder fully exercised its right to
convert the shares of Series B Preferred Stock into Common Stock immediately
prior to the record or determination date for such Liquidating Dividend. In
addition, if InSight issues any shares of Common Stock or securities convertible
into, or exercisable for, shares of Common Stock at a common stock equivalent
price of less than the Conversion Price in effect at the time of such issuance,
then, subject to certain exceptions, such Conversion Price shall be adjusted in
accordance with certain price-based antidilution provisions.

    The Series B Preferred Stock may be converted only in a Type A Conversion
or a Type B Conversion, as described below.

    TYPE A CONVERSION.  Each holder of Series B Preferred Stock has the right,
at its option, at any time, to convert all, but not less than all, of its Series
B Preferred Stock then outstanding into such number of shares of Common Stock as
results from dividing (i) the sum of (A) the aggregate Liquidation Preference of
all shares of Series B Preferred Stock to be converted plus (B) any declared but
unpaid dividends on such shares, by (ii) the applicable Conversion Price on the
date of conversion (the "Conversion Date").  In addition, substantially
contemporaneous with any Partial Conversion Event (defined to mean (a) the sale
at any time of a holder's Series B Preferred Stock to a third party approved by
the Board, (b) the consummation at any time of a public offering of Common Stock
and (c) the consummation of a private sale of Common Stock after April 14,
1999), each holder of Series B Preferred Stock has the right, at its option, to
convert all or any part of its Series B Preferred Stock into such number of
shares of Common Stock as results from dividing (i) the sum of (A) the aggregate
Liquidation Preference of all shares of Series B Preferred Stock to be converted
plus (B) any declared but unpaid dividends on such shares, by (ii) the
applicable Conversion Price on the Conversion Date.

    TYPE B CONVERSION.  At any time on or after October 22, 1998 (the "Type B
Trigger Date"), the holders of a majority of the Series B Preferred Stock may
elect to deliver an irrevocable notice (a "Type B Conversion Notice") to convert
all of their Series B Preferred Stock into Series D Preferred Stock, provided
that such notice shall not be effective unless substantially contemporaneous
with its delivery the holders of a majority of the Series C Preferred Stock
deliver a similar notice to convert all of their Series C Preferred Stock into
Series D Preferred Stock.  On the date of delivery of the Type B Conversion
Notice (the "Type B Event Date") each share of Series B Preferred Stock then
outstanding shall automatically be converted into such number of shares of
Series D Preferred Stock as results from dividing (i) the sum of (A) the
aggregate Series B Liquidation Preference of such share of Series B Preferred
Stock plus (B) any declared but unpaid dividends on such share, by (ii) the
product of ten (10) times the applicable Conversion Price on the Type B Event
Date.  Each outstanding share of Series C Preferred Stock will also
automatically be converted into Series D Preferred Stock based upon a similar
formula.  The rights of holders of Series B Preferred Stock with respect to a
Type B Conversion are not transferable except to an affiliate of an initial
purchaser of Series B Preferred Stock.

    REDEMPTION.  The Series B Preferred Stock is not subject to mandatory
redemption by InSight or the holder thereof, pursuant to InSight's or such
holder's unilateral election.

    VOTING AND RELATED RIGHTS.  Holders of Series B Preferred Stock have the 
right to vote with the holders of Common Stock and the holders of Series C 
Preferred Stock with respect to all matters submitted to a stockholder vote, 
except for the election of directors (with respect to which the holders of 
the Series B Preferred Stock have the voting rights set forth in "Composition 
of Board" below).  With respect to all matters submitted to a stockholder 
vote (except for the election of directors), each holder of Series B 
Preferred Stock has one vote for every share of Common Stock into which each  
share of Series B Preferred Stock is then convertible, provided that the 
aggregate number of such votes, when combined with the aggregate number of 
votes attributable to the holders of Series C Preferred  Stock, shall not 
exceed 37% of the total number of votes eligible to be cast.

    SUPERMAJORITY BOARD VOTE. Prior to a Type B Event Date, approval of at
least six directors is required for the approval of the annual capital budget
plan and for any financing activity not approved by the Executive Committee (as
defined below) of the Board.

    BYLAW AMENDMENTS.  InSight's Bylaws may be amended, repealed or replaced by
InSight's stockholders or the Board only upon approval by (i) in the case of
adoption by the Board, prior to the first meeting of the newly constituted Board
held two calendar days after a Type B Event Date (a "First Meeting"), a majority
of the Preferred Stock Directors (as defined below) and either (A) a majority of
the entire Board (if such amendment, repeal or replacement does not increase the
size of the Board) or (B) at least 80% of the members of the entire Board (if
such amendment, repeal or replacement does increase the size of the Board); or
(ii) in case of adoption by the stockholders with a record date on or before a
Type B Event Date,  holders of at least 80% of the outstanding shares entitled
to vote in the election of directors, voting as one class, and by holders of a
majority of the shares outstanding as of such record date of whichever (or both)
of Series B Preferred Stock or Series C Preferred Stock continued  (as of such
record date) to have the right to elect one or more Preferred Stock Directors.

    PROTECTIVE PROVISIONS.   For so long as the Carlyle Stockholders and 
certain affiliates thereof own at least 33% of the Series B Preferred Stock, 
the approval of the holders of at least 67% of the Series B Preferred Stock 
is required before the Company may take the following actions:  (a) alter, 
change or amend (by merger or otherwise) any of (i) the rights, preferences 
and privileges of the Series B Preferred Stock or any other class of capital 
stock; or (ii) the terms or provisions of any option or convertible security; 
(b) enter into any transaction or event that could result in a Special 
Corporate Event with respect to InSight or any subsidiary (defined to include 
the acquisition of more than 20% of the voting power, a change in a majority 
of the board of directors other than pursuant to a Type B Event, a merger 
resulting in a change in ownership of 50% or more of the voting securities of 
the Person surviving such merger or the sale of all or substantially all of 
the assets); (c) initiate any Liquidating Event with respect to InSight or 
any subsidiary; (d) amend, restate, alter, modify or repeal (by merger or 
otherwise) the Certificate of Incorporation or the Bylaws of InSight, 
including, without limitation, amendment, restating, modifying or repealing 
(by merger or otherwise) any certificate of designation or preferences 
relating to the Series B Preferred Stock, the Series C Preferred Stock or the 
Series D Preferred Stock;  (e) amend, restate, alter, modify or repeal (by 
merger or otherwise) or permit any subsidiary to amend, restate, alter, 
modify or repeal (by merger or otherwise) the certificate of incorporation, 
other organizational documents, or bylaws of any subsidiary in any material 
respect; (f) change the number of directors of InSight to a number less than 
eight or more than nine or the manner in which the directors are selected, as 
provided in the Certificate of Incorporation, Bylaws, Series B Preferred 
Stock Certificate of Designation, the Certificate of Designations, 
Preferences and Rights of Convertible Preferred Stock, Series C (the "Series 
C Certificate of Designation"), and the Certificate of Designations, 
Preferences and Rights of Convertible Preferred Stock, Series D (the "Series 
D Certificate of Designation");  (g) except with respect to the Bank 
Financing, or any other credit facility existing as of October 14, 1997, 
incur any indebtedness, in the aggregate with respect to InSight and its 
subsidiaries, in excess of $15 million in any fiscal year;  (h) become a

present value of all payments due during the term of such operating leases in 
the aggregate (determined using a discount rate of 10%) exceed $15 million;  
(i) create, authorize or issue any shares of Series B Preferred Stock or any 
class or series of

Senior Securities, Parity Securities, or securities having the right to cast

Common Stock in the aggregate, in which senior management of the Company shall
not participate, (B) management stock options exercisable at not less than the
then-applicable Conversion Price per share of Common Stock issued after October

transactions, any equity ownership interest or interests of any Person, where

to the consummation of such merger or consolidation shall, immediately after the
consummation of such merger or consolidation, hold securities possessing more
than 50% of both the total voting power of and the beneficial ownership

InSight), or cause or permit any other Person to merge into such subsidiary,
where the stockholders of such subsidiary immediately prior to the consummation
of such merger or consolidation shall, immediately after the consummation of
such merger or consolidation, hold 50% or less of either the total voting power
of or the beneficial ownership interests in the surviving entity of such merger

such Partial Subsidiary, such Partial Subsidiary is designated as such in a

and (iii) no liabilities of such Partial Subsidiary are ever assumed or
guaranteed by InSight or any other subsidiary; or  (v) issue any share of Series
D Preferred Stock, otherwise than pursuant to a Type B Conversion.

"Market Price" means as to any security the average of the closing prices of any
such  security's sales on all domestic securities exchanges on which such
security may at the time be listed, or, if there have been no sales on any such
exchange on any day, the average of the highest bid and lowest asked prices on
all such exchanges at the end of such day, or, if on any day such security is
not so listed, the average of the representative bid and asked prices quoted in
Nasdaq as of 4:00 p.m., New York time, on such day, or, if on any day such
security is not quoted in Nasdaq, the average of the highest bid and lowest
asked prices on such day in the domestic over-the-counter market as reported by
the National Quotation Bureau, Incorporated, or any similar successor
organization, in each such case averaged over a period of 21 business days
consisting of the day as of which Market Price is to be determined and the 20
consecutive business days prior to such day.  If such security is not so listed
or quoted, Market Price shall be the fair market value of such security
determined by the Company and the holders of a majority of the Series B
Preferred Stock in accordance with certain procedures.

    PREEMPTIVE RIGHTS.  The holders of Series B Preferred Stock have a right 
of first offer with respect to future sales in any transaction or proposed 
transaction not involving a public offering by  InSight of Common Equity 
(including Common Stock) or any securities convertible or exchangeable into 
Common Equity, excluding offers of Common Stock pursuant to options granted 
to its officers, directors and employees for the primary purpose of 
soliciting or retaining their employment or services (the "Preemptive 
Securities").  With respect to any proposed offering by InSight of Preemptive 
Securities in which the proposed sale price reflects a price per share of 
Common Stock at or above the higher (the "Trigger Price") of (i) the Market 
Price per share of Common Stock as of the date of InSight's written notice 
(the "Preemptive Notice") to such holders regarding the proposed offering or 
(ii) $8.375 per share of Common Stock (a "Type A Offering"), each holder may 
elect to purchase, pursuant to specified procedures, at the price and on the 
terms specified in the Preemptive Notice, up to that portion of Preemptive 
Securities which equals the proportion that the number of shares of Common 
Stock issuable upon conversion of the Series B Preferred Stock then held by 
such holder bears to the total number of shares of Common Stock then 
outstanding (assuming full conversion of all convertible securities, 
including all Series B Preferred Stock, Series C Preferred Stock and Series D 
Preferred Stock).  With respect to any proposed offering by InSight of 
Preemptive Securities in which the proposed sale price reflects a price per 
share of Common Stock below the Trigger Price (a "Type B Offering"), each 
holder may elect to purchase, pursuant to specified procedures, at the price 
and on the terms specified in the Preemptive Notice, up to that portion of 
Preemptive Securities which equals the proportion that the number of shares 
of Common Stock issuable upon conversion of the Series B Preferred Stock then 
held by such holder bears to the total number of shares of Common Stock into 
which the outstanding shares of Series B Preferred Stock are then 
convertible.  Certain procedures are provided to permit holders of Series B 
Preferred Stock to purchase Preemptive Securities which  other holders of 
Series B Preferred Stock decline to purchase.   In the event that there 
remain any unpurchased Preemptive Securities InSight may offer and sell the

                                        - 7 -
<PAGE>

remaining unsubscribed portion of such Preemptive Securities, on the same terms
and conditions specified in the Preemptive Notice to any Person for a specified
period of time.

THE SERIES C PREFERRED STOCK

    The rights, preferences and privileges of the Series C Preferred Stock, as
set forth in the Series C Certificate of Designation, are substantially the same
as those described above with respect to the Series B Preferred Stock
(substituting therein "Series C Preferred Stock" for "Series B Preferred Stock"
and "Series B Preferred Stock" for "Series C Preferred Stock",  as the case may
be), except as set forth below in "Composition of the Board." Such description
does not purport to be complete and is subject to and qualified in its entirety
by reference to the Series C Certificate of Designation, a copy of which is
filed as Exhibit 3.3 to the 1997 Form 10-K.

THE SERIES D PREFERRED STOCK

    The following is a brief description of the rights, preferences and
privileges of the Series D Preferred Stock as set forth in the Series D
Certificate of Designation. Such description does not purport to be complete and
is subject to and qualified in its entirety by reference to the Series D
Certificate of Designation, a copy of which is filed as Exhibit 3.4 to the 1997
Form 10-K.

    RANK.  The Series D Preferred Stock ranks on a parity with the Series B
Preferred Stock and the Series C Preferred Stock.

    DIVIDEND RIGHTS.  Each holder of Series D Preferred Stock is entitled to 
receive dividends (when, as and if declared by the Board) together with 
holders of Series B Preferred Stock, Series C Preferred Stock and Common 
Stock on a basis proportionate to the number of shares of Common Stock held 
by such holder (assuming conversion of all Preferred Stock).

    LIQUIDATION PREFERENCE.  Upon any Liquidating Event, the holders of the
Series D Preferred Stock then outstanding shall be entitled to be paid $.001 per
share of Series D Preferred Stock, plus any declared but unpaid dividends
thereon, before any payment shall be made on any assets distributed to the
holders of any of the Junior Securities, including Common Stock.  In addition,
holders of Series D Preferred Stock shall be entitled to receive any
distribution in the event of liquidation, dissolution or winding up of the
affairs of the Company on a parity with shares of Common Stock , on a pro rata
basis (assuming full conversion of all shares of Series D Preferred Stock into
Common Stock).

    CONVERSION RIGHTS.  Each holder of Series D Preferred Stock shall have the
right, at its option, to convert all or any part of its Series D Preferred Stock
into such number of shares of Common Stock as results from multiplying the
number of shares of Series D Preferred Stock to be converted by the Conversion
Multiple.  The "Conversion Multiple" is initially ten (10) and is subject to (i)
increase if InSight at any time subdivides (by stock split, stock dividend,
reclassification, recapitalization or otherwise) one or more classes or series
of its outstanding Common Equity into a greater number of shares or (ii)
decrease if InSight at any time combines (by reverse stock split or otherwise)
one or more classes or series of its outstanding Common Equity into a smaller
number of shares.  In the event of any Corporate Change, each share of Series D
Preferred Stock then outstanding will become convertible only into the kind and
amount of securities, cash and other property receivable upon such Corporate
Change by the holder of the number of shares of Common Stock into which such
share of Series D Preferred Stock was convertible immediately prior thereto.  If
InSight declares or pays a Liquidating Dividend, InSight shall pay to each
holder of a share of Series D Preferred Stock the Liquidating Dividend that
would have been paid to such holder on the Common Stock such holder would have
owned had such holder fully exercised its right to convert the shares of Series
D Preferred Stock into Common Stock immediately prior to the record or
determination date for such Liquidating Dividend.


                                        - 8 -
<PAGE>

    REDEMPTION.  The Series D Preferred Stock is not subject to mandatory
redemption by InSight or the holder thereof, pursuant to InSight's or such
holder's unilateral election.

    VOTING RIGHTS.  Holders of Series D Preferred Stock have the right to vote
with the holders of Common Stock with respect to all matters submitted to a
stockholder vote, except for the election of directors (with respect to which
the holders of the Series D Preferred Stock have the voting rights set forth in
"Composition of Board" below).  With respect to all matters submitted to a
stockholder vote (except for the election of directors), each holder of Series D
Preferred Stock will have one vote for every share of Common Stock into which
each  share of Series D Preferred Stock is then  convertible.

    PROTECTIVE PROVISIONS.  The approval of the holders of at least 67% of the
Series D Preferred Stock is required before the Company may take the following
actions: (a) create, authorize or issue any shares of Series D Preferred Stock
or any class or series of Supervoting Securities or shares of such class or
series; (b) reclassify any authorized stock of InSight into Series D Preferred
Stock or any class or series of Supervoting Securities or shares of any such
class or series; or (c) increase or decrease the authorized number of shares of
Series D Preferred Stock or any class or series of Supervoting Securities or
shares of any such class or series.

COMPOSITION OF THE BOARD

    Pursuant to the terms of the Recapitalization, the number of directors
comprising the Board is currently fixed at nine.  Six directors (the "Common
Stock Directors") are to be elected by the Common Stock holders, one of whom
(the "Joint Director") is to be proposed by the majority holders 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
(the "Preferred Stock Directors"), two are to be elected by the holders of the
Series B Preferred Stock and one is to be elected by the holders of the Series C
Preferred Stock, in each case acting by written consent and without a meeting of
the Common Stock holders.  As long as the Carlyle Stockholders and certain
affiliates thereof own at least 50% of the Series B Preferred Stock originally
purchased thereby, the holders of the Series B Preferred Stock will have the
right to elect two Preferred Stock Directors (the "Series B Director" or "Series
B Directors", as the case  may be) and as long as the Carlyle Stockholders and
certain affiliates thereof own at least 25% of such stock, such holders will
have the right to elect one Series B Director.  As long as GE owns at least 25%
of the Series C Preferred Stock originally purchased thereby,  it will have the
right to elect one Preferred Stock Director (the "Series C Director").  Except
in the event of a Type B Conversion, 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 Carlyle Stockholders or GE
will initially be appointed by the Board and  thereafter, be elected by the
Common Stock holders.

    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.

    In the event of a Type B Conversion, the number of members of the Board
will be increased automatically by the smallest whole number that will result in
at least the Type B Percentage (but less than 66 2/3%) of the members of the
Board being Series D Directors.  Immediately following a Type B Event Date, the
holders of Series D Preferred Stock shall have the right to elect all of the new
directors (the "Conversion Directors") using cumulative voting.  The "Type B
Percentage" equals a percentage equal to the number of shares of Common Stock


                                        - 9 -
<PAGE>

held by all holders of Series B Preferred Stock and Series C Preferred Stock as
of the Type B Event Date (assuming conversion of all such shares of Series B
Preferred Stock and Series C Preferred Stock into Common Stock) divided by the
total number of shares of Common Stock outstanding as of such date (assuming
conversion of all shares of Series B Preferred Stock and Series C Preferred
Stock as of such date); provided that the maximum Type B Percentage is 64%.
"Series D Directors" means, collectively, the Preferred Stock Directors and the
Conversion Directors.

    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.

    COMMITTEES OF THE BOARD.  Pursuant to the terms of the Series B Certificate
of Designation and the Series C Certificate of Designation, the following
committees  of the Board were created or reconstituted, as applicable, with the
respective duties, membership and voting requirements stated below:

    COMPENSATION COMMITTEE.  The Compensation Committee consists of three
members, at least one of whom is to be selected jointly by the Preferred Stock
Directors.  The affirmative vote of at least two members of the Compensation
Committee is required for approval of matters considered by the Compensation
Committee.

    AUDIT COMMITTEE.  The Audit Committee consists of three members, including
as many independent directors as are available.  An affirmative vote of at least
two members of the Audit Committee is required for approval of matters
considered by the Audit Committee.

    EXECUTIVE COMMITTEE.  The Executive Committee consists of four members, one
of whom is to be selected by the Series B Directors (and shall be a Series B
Director), one of whom shall be the Series C Director and two of whom are to be
selected by the Board.  The affirmative vote of at least three members of the
Executive Committee is required for approval of matters considered by the
Executive Committee.

    ACQUISITIONS COMMITTEE.  The Acquisitions Committee consists of four
members, one of whom is to be selected by the Series B Directors (and shall be a
Series B Director), one of whom shall be the Series C Director and two of whom
are to be selected by the Board (and shall be directors).  The Acquisitions
Committee has the right to approve certain transactions where the aggregate
consideration payable is less than $15 million. A unanimous vote is required for
approval of matters considered by the Acquisitions Committee, although certain
matters which do not receive the Committee's unanimous approval may be referred
to the Board for approval by a majority of its members.  The unanimous approval
of the Acquisitions Committee or of the Board is required for certain
transactions in which the aggregate consideration payable is less than $15
million and the Company is to issue its Common Equity at an implicit or explicit
price of less than $8.375 per share.

    The foregoing Committees must be maintained by the Company until a Type B
Event Date unless otherwise approved by a majority of the Board and a majority
of the Preferred Stock Directors, provided that if the holders of the Series B
Preferred Stock cease to have the right to nominate and elect a Series B
Director (other than as a result of conversion of the Series B Preferred Stock
in a Type B Conversion), the holders of the Series B Preferred Stock shall no
longer have the right to select Committee members and their designees on such
Committees shall automatically cease to be members thereof.

TRANSFER RESTRICTIONS


                                        - 10 -
<PAGE>

    Pursuant to the definitive agreements relating to the Recapitalization,
each of the Carlyle Stockholders and GE has agreed (i) not to transfer, sell,

interest in any shares of Series B Preferred Stock or Series C Preferred Stock
without the prior approval of the Board, in its sole discretion,  and (ii) not
to transfer, sell or assign to an affiliate any interest in any shares of Series
B Preferred Stock or Series C Preferred Stock if such affiliate is engaged in
the provision of diagnostic services to the healthcare industry.

    In addition, until the earlier to occur of April 14, 1999 or a Type B 
Event Date, each of the Carlyle Stockholders and GE has agreed not to

the Common Stock issuable upon conversion of the Series B Preferred Stock 
(the "Series B Conversion Shares") (with respect to the Carlyle 
Stockholders), the Common Stock issuable upon conversion of the Series C 
Preferred Stock (the "Series C Conversion Shares") (with respect to GE) or 
the Common Stock issuable upon conversion of the Series D Preferred Stock (the

permitted under Rule 144 of the Securities Act of 1933, as amended (the 
"Securities Act"), (iii) a transfer pursuant to a registered offering 
pursuant to Registration Rights Agreements (described below) or (iv) a 
transfer pursuant to a transaction available to all stockholders of the

    If a Type B Event occurs prior to April 14, 1999, then from the Type B 
Event Date until the second subsequent annual meeting of the Company's 
stockholders after such Type B Event Date, each of the Carlyle Stockholders 
and GE has agreed not to make a transfer of any of its Series D Preferred 
Stock, Series B Conversion Shares (in the case of the Carlyle Stockholders), 
the Series C Conversion Shares (in the case of GE) or the Series D Conversion 
Shares (i) in a transaction available to all holders of Common Stock on the 
same terms as to the Carlyle Stockholders or GE, as applicable, unless such 
transaction has been approved by either (a) the affirmative vote of not less 
than 80% of the outstanding shares of the Company entitled to vote (which 
include the Common Stock and the Series D Preferred Stock) or (b) at least 
two-thirds of the Company's directors (which must include, to the extent 
still a director, either (1) the Joint Director, if such Joint Director 
served in such position as of the Type B Event Date or has been approved by a 
majority of the directors who were Common Stock Directors as of the Type B 
Event Date or (2) at least one director who was a Common Stock Director prior 
to the Type B Event Date); or (ii) in a transaction other than one available 
to all holders of Common Stock on the same terms as to the Carlyle 
Stockholders or GE, as applicable, unless such transaction has been approved 
either by (a) the affirmative vote of not less than 80% of the outstanding 
shares  of the Company entitled to vote or (b) at least 50% of the Company's 
directors who are not the Preferred Stock Directors or the Conversion 
Directors.

    If the Type B Event Date is prior to October 14, 1999, then from the Type B
Event 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: (a) any merger or consolidation of the Company or any
of its subsidiaries with or into such Person; (b) any sale, lease, exchange or

least 80% of the Company's outstanding shares entitled to vote (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 Type B Event Date or has been approved by a majority of the directors who
were Common Stock Directors as of


                                        - 11 -
<PAGE>

the Type B Event Date or (B) at least one director who was a Common Stock
Director prior to the Type B Event Date).

    The Carlyle Warrants and the GE Warrants and the Common Stock issuable upon
exercise of such Warrants are transferable by the Carlyle Stockholders and GE,
as applicable, subject to compliance with federal and state securities laws,
without the Board's approval.

REGISTRATION RIGHTS

    The Company has granted certain registration rights to the Carlyle
Stockholders and GE with respect to the Series B Preferred Stock, the Series C
Preferred Stock, the Series D Preferred Stock, the Carlyle Warrants and the GE
Warrants.  Pursuant to separate Registration Rights Agreements dated October 14,
1997 with (i) the Carlyle Stockholders and (ii) GE, upon the demand of the
Carlyle Stockholders or GE, as applicable, the Company will use commercially
reasonable efforts to effect the registration (a "Demand Registration") under
the Securities Act, of such number of Registrable Securities (as defined below)
as are requested to be registered.  The Company will be obligated to effect no
more than two Demand Registrations for each of the Carlyle Stockholders and GE
and in each such case the aggregate public offering price of the Registrable
Securities to be registered must be at least $5 million. The Carlyle
Stockholders may elect to join in a GE Demand Registration with respect to a
number of shares less than or equal to the number of shares which is the subject
of the GE Demand Registration, and GE may similarly elect to join in a Demand
Registration of the Carlyle Stockholders.  In either case, the party electing to
join in the other party's Demand Registration will not be charged with a Demand
Registration of its own for purposes of the two Demand Registration limit. Under
certain circumstances, the number of Registrable Securities that the Carlyle
Stockholders or GE will be entitled to include in a Demand Registration will be
limited.

    "Registrable Securities" means (a) with respect to the Carlyle
Stockholders, (i) the Common Stock issued or issuable upon conversion of the
Series B Preferred Stock and the Series D Preferred Stock, whether or not owned
by the Carlyle Stockholders, (ii) the Common Stock issued or issuable upon
exercise of the Carlyle Warrants, whether or not owned by the Carlyle
Stockholders, (iii) any securities issued or issuable with respect to such
Common Stock by way of a stock dividend or stock split or in connection with a
combination of shares, recapitalization, merger, consolidation or
reorganization; and (iv) any Common Stock or securities issuable with respect to
such Common Stock as provided in (iii) above, acquired by the Carlyle
Stockholders from the Company subsequent to October 14, 1997, whether or not
owned by the Carlyle Stockholders at the time of such registration; and (b) with
respect to GE, (i) the Common Stock issued or issuable upon conversion of the
Series C Preferred Stock and the Series D Preferred Stock, whether or not owned
by GE, (ii) the Common Stock issued or issuable upon exercise of the GE
Warrants, whether or not owned by GE, (iii) any securities issued or issuable
with respect to such Common Stock by way of a stock dividend or stock split or
in connection with a combination of shares, recapitalization, merger,
consolidation or reorganization; and (iv) any Common Stock or securities
issuable with respect to such Common Stock as provided in (iii) above, acquired
by GE from the Company subsequent to October 14, 1997, whether or not owned by
GE at the time of such registration.  Securities cease to be Registrable
Securities once they have been sold to or through a broker, dealer or
underwriter in a public distribution or other public securities transaction or
sold in a transaction pursuant to Rule 144 under the Securities Act.

    In addition, if the Company proposes to register any of its securities for
sale for cash, each of the Carlyle Stockholders and GE, upon request, will have
the right to include the number of Registrable Securities such party wishes to
sell or distribute publicly under the registration statement proposed to be
filed by the Company and the Company will use commercially reasonable efforts to
register under the Securities Act the sale of such Registrable Securities (a
"Piggyback Registration").  Under certain circumstances, the number of
Registrable Securities that the Carlyle Stockholders or GE will be entitled to
include in a Piggyback Registration will be limited.


                                        - 12 -
<PAGE>

The Registration Rights Agreements contain customary provisions regarding the
payment of expenses by the Company and regarding mutual indemnification and
contribution agreements between the Company and the holders of the Registrable
Securities.

THE CARLYLE WARRANTS AND THE GE WARRANTS

    Each of the Carlyle Warrants and the GE Warrants represent the right to
purchase at any time until the expiration of such Warrants on October 14, 2002,
up to 250,000 shares of Common Stock at an initial purchase price of $10.00 per
share.  The exercise price and the number of shares issuable upon exercise of
the Warrants are subject to adjustment under certain circumstances.

issuances of Common Stock referred to in clauses (1), (2), (3), (4) and (5) 
thereof were made immediately following the Closing, whether or not the 
Company is or could be under any obligation to issue such shares of Common

    relationship with such Persons) or to amend or modify any existing Employee
    Plan.  Each Employee Plan can be amended or terminated at any time without
    approval from any Person, without advance notice and without any liability
    other than for benefits accrued prior to such amendments or termination.

                   (xi)     NO OTHER MATERIAL LIABILITY.  To the Knowledge of

    any ERISA Affiliate or 

                                       24
<PAGE>

    any Employee Plan, directly or indirectly, could be subject to any material
    liability (A) under any statute, regulation or governmental order 
    relating to any Employee Plan or (B) pursuant to any obligation of the

    contract or any other investment or insurance contract issued by an
    insurance company that is the subject of bankruptcy, conservatorship or
    rehabilitation proceedings.

                   (xiii)   NO ACCELERATION OR CREATION OF RIGHTS.  Except as
    disclosed on Schedule 4.8, neither the execution and delivery of this
    Agreement by the Company nor the consummation of all or any portion of the
    Transaction will result in the acceleration or creation of any rights of
    any person to benefits under any Employee Plan (including, without
    limitation, the acceleration of the vesting or exercisability of any stock
    options, the acceleration of the vesting of any restricted stock, the
    acceleration of the accrual or vesting of any benefits under any Pension
    Plan or the acceleration or creation of any rights under any severance,
    parachute or change in control agreement).

              (c)  There are no employment, consulting, change of control,
severance pay, continuation pay, termination pay, loans, guarantees or
indemnification agreements or other similar agreements of any nature whatsoever
(collectively, "Employment Agreements") between the Company, on the one hand,
and any current or former stockholder, officer, director, employee or Affiliate
of the Company or any consultant or agent of the Company, on the other hand,
that, as a direct result of the Transaction, (i) will require any payment by the
Company or any consent or waiver from any stockholder, officer, director,
employee or Affiliate of the Company or any consultant or agent of the Company,
or (ii) will result in any change in the nature of any rights of any
stockholder, officer, director, employee or Affiliate of the Company or any
consultant or agent of the Company under any such Employment Agreement or other
similar agreement (including, without limitation, any accelerated payments,
deemed satisfaction of goals or conditions, new or increased benefits or
additional or accelerated vesting).

                                       25
<PAGE>

material fact required to be stated therein or necessary in order to make the

heretofore furnished or made available to the Purchaser true, correct and 
complete copies of all SEC Filings since June 30, 1996. 

              (b)  Since June 30, 1992, all material reports, documents and

condition of the Company and the Subsidiaries and the consolidated results of 
operations as of such dates and for such periods indicated.  Since April 30,

all material respects in the ordinary course and contain a materially correct 
and complete record of the matters typically contained in records of such 
nature.

              (b)  The Company has not received any management letters or 
other letters (other than audit letters included in the SEC Filings) from the 
Company's independent auditing firm(s) relating to the results of operations,

4.13 COMPLIANCE WITH LAWS. 

              (a)  The Company and its Subsidiaries are in compliance in all 
material respects with all material Applicable Laws.  Material Applicable 
Laws includes, without limitation, all Applicable Laws relating to health 
care, the health care industry and the provision of health care services, 
third party reimbursement (including Medicare and Medicaid), public health 
and safety and wrongful death and medical malpractice.  Neither the Company 
nor any of its Subsidiaries has received any notice of, nor does the Company 
or any of its Subsidiaries have any Knowledge of, any violation (or of any 
investigation, inspection, audit or other proceeding by any Governmental 
Entity involving allegations of any violation) of any Applicable Law 
involving or related to the Company or any of its Subsidiaries which has not 
been dismissed or otherwise disposed of.  Except as set forth in SCHEDULE 
4.13(A), neither the Company nor any of its Subsidiaries has received notice 
or otherwise has any Knowledge that the Company or any Subsidiary is charged 
with, threatened with or under investigation with respect to, any violation 
of any Applicable Law, or has any Knowledge of any proposed change in any 
Applicable Law that would have a Material Adverse Effect on the Transaction 
or the Company.

              (b)  Each of the Company and its Subsidiaries has, and all 
professional employees or agents of each of the Company and its Subsidiaries 
who are performing health care or health care related functions on behalf of 
the Company or any of its Subsidiaries or joint ventures have, all material 
licenses, franchises, permits, accreditations, provider numbers, 
authorizations, including certificates of need, consents or orders of, or 
filings with, or other approvals from all Governmental Entities ("Approvals") 
necessary for the conduct of, or relating to the operation of, the business 
of each of the Company and its Subsidiaries and the occupancy and operation, 
for its present uses, of the real and personal property which each of the 
Company and its Subsidiaries owns or leases, and neither the Company nor any 
Subsidiary or the professional employees or agents of either (acting in such 
capacities) is in violation of any such Approval in any material respect or 
any terms or conditions thereof.  All such Approvals are in full force and 
effect, have been issued to and fully paid for by the holder thereof and no 
notice or warning from any Governmental Entity with respect to the 
suspension, revocation or termination of any Approval has been, to the 
Knowledge of the Company, threatened by any Governmental Entity or issued or 
given to the Company or any Subsidiary.  No such Approvals will in any way be 
affected by, terminate or lapse by reason of the consummation of all or any 
portion of the Transaction.  There are no physicians (other than radiologists 
and radiation oncologists) owning Capital Stock in any Subsidiary, and no 
physicians own stock in the Company, except for physician ownership of 
publicly traded stock of the Company acquired on terms equally available to 
the public through trading on the Nasdaq Stock Market, and no physician owns 
5% or more of the outstanding shares of any class of securities issued by the 
Company.

4.14 LITIGATION.  

              Except as set forth on SCHEDULE 4.14 hereto, there is no
Proceeding (by any Governmental Entity or otherwise) of which the Company has
received notice or of which the Company has Knowledge pending against or
affecting the Company, any Subsidiary or the assets, products  or business of
any of them or, to the Knowledge of the Company, any basis 

                                       28
<PAGE>

therefor or threat thereof.  Except as set forth on SCHEDULE 4.14 hereto, 
neither the Company nor any Subsidiary is a party or subject to the 
provisions of any order, writ, injunction, judgment or decree of any court or 
other Governmental Entity. Except as set forth on SCHEDULE 4.14 hereto, there 
is no Proceeding by the Company or any Subsidiary currently pending or that 
the Company or any Subsidiary currently intends to initiate.  There are no 
Proceedings pending or, to the Knowledge of the Company, threatened against 
the Company, any Subsidiary or any of their respective businesses, assets or 
products that seek to enjoin, question the validity of or rescind the 
Transaction, the GE Purchase Agreement, the Ancillary Agreements or otherwise 
prevent the Company from complying with the terms and provisions of this 
Agreement, the GE Purchase Agreement, the Ancillary Agreements or any of such 
other agreements.  Any and all Liabilities of the Company and its 
Subsidiaries under such Proceedings that are probable and subject to 
reasonable estimation within the meaning of GAAP are adequately covered 
(except for standard deductible amounts) by the existing insurance maintained 
by the Company or estimates in accordance with GAAP for the uninsured costs 
thereof are reflected in the Financial Statements.  No holder of shares of 
the Capital Stock of either American Health Services Corp. or Maxum Health 
Corp. (constituent corporations in the mergers contemplated by the Merger 
Agreement) that either were outstanding immediately prior to such mergers 
made a demand for the appraisal of his shares pursuant to Section 262 of the 
Delaware General Corporation Law.

4.15 TRUE AND COMPLETE DISCLOSURE.  

              Taken as a whole, this Agreement, the GE Purchase Agreement, 
the Ancillary Agreements, the Exhibits, Schedules, statements and 
certifications made or delivered in connection herewith or therewith, do not 
contain any untrue statement of a material fact or omit to state a material 
fact necessary to make the statements herein or therein not misleading.  All 
financial projections reflected in the 1998 budget provided by the Company to 
the Purchaser were prepared in good faith on the basis of assumptions 
believed to be reasonable at the time such projections were prepared.

4.16 TAXES. 

              (a)  All Company Tax Returns have been properly and timely 
filed and all such Tax Returns are correct and complete in all material

Subsidiaries files a consolidated or combined Tax Return has filed all such 
Tax Returns that it was required to file for each taxable period during which 
any of the Company and its Subsidiaries was a member of the group.  All such 
consolidated and combined Tax Returns were correct and complete in all

Preferred Stock then outstanding, (b) the issuance of Common Stock in respect of
the Warrants and the GE Warrants, and (c) if any Series D Preferred Stock is

and Series D Preferred Stock and the exercise of all the then outstanding 
Warrants and GE Warrants, in addition to such other remedies as shall be 
available to the holders of the Series B Preferred Stock, Series C Preferred

which the Company's stockholders shall vote on a proposed amendment to the

appropriate, a favorable vote for which amendment shall have been recommended 
to the Company's stockholders by the Board of Directors, pursuant to a duly 
and validly adopted resolution of the Board of Directors setting forth the 
amendment proposed and declaring its advisability, all in accordance with 
Section 242 of the Delaware General Corporation Law; and, in case of an 
increase in the number of authorized shares of such preferred stock, the 
Board of Directors shall promptly cause to become effective a certificate of 
increase pursuant to Section 151 of the Delaware General Corporation Law.

    directors, respectively, who selected such members.  The Executive
    Committee shall, in addition to the customary duties of an executive
    committee, have the right to approve any financing activity, including but

    matter considered but not unanimously approved by the Acquisitions
    Committee may be referred to the Board of Directors for approval, which

              (iv)    any dissolution or liquidation of the Company;

PROVIDED, HOWEVER, that the prohibitions contained in this sentence shall not
apply with respect to any such action or transaction approved by (I) the
affirmative vote of not less than 80 percent of the outstanding shares of the
Company entitled to vote or (II) at least two-thirds (2/3) of the directors of
the Company (which must include either the Joint Director if either (x) such
Joint Director served in such position as of the Type B Event Date, or (y) such
Joint Director has been approved by a majority of directors who were Common
Stock Directors as of Type B Event Date, or at least one director who was a
Common Stock Director prior to the Type B Event Date, unless neither such Joint
Director, nor any of such Common Stock Directors continue to serve on the Board
of Directors at such time).  For purposes of the immediately preceding sentence,
a Person shall be deemed to own or control directly or indirectly, any
outstanding shares of stock of the Company (A) which it has the right to acquire
pursuant to any agreement, or upon the exercise of, conversion rights, warrants,
options or otherwise or (B) which are beneficially owned, directly or indirectly
(including shares deemed owned through application of clause (A) above) by any
other corporation, person or other entity (x) with which it or its "affiliate"
or "associate," (as defined below) has any agreement, arrangement, or
understanding for the purpose of acquiring, holding, voting or disposing of
stock of the Company or (y) which is its "affiliate" or "associate" as those
terms are defined under the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated thereunder.

No transfer of Series B Preferred Stock or Series B Conversion Shares may be
made by Purchaser or any Carlyle Affiliate (other than a transfer described in
paragraph (b)(ii) or (b)(iii) of this Section 6.14), unless prior thereto, the
transferee in such transfer shall have entered into an agreement in form and
substance reasonably satisfactory to the Company, agreeing to be bound by the
terms of this Section 6.14(c).  Notwithstanding anything to the contrary
contained in this Section 6.14(c), the Purchaser shall not need any approval by
any directors, the Board of Directors or any stockholders under this Section
6.14 in order to transfer, sell or assign any of its Series B Conversion Shares
in the circumstances and the persons set forth in clauses (i), (ii) and (iii) of

opinion of reputable legal counsel in form reasonably acceptable to the Company
that such sale or transfer is being made in compliance with applicable federal
securities laws.

HOWEVER, that to the extent that such covenants relate to or arise out of any
Applicable Laws relating to health care, the health care industry and the
provision of health care services, third party reimbursement (including Medicare
and Medicaid), public health and safety and wrongful death and medical
malpractice), such covenants shall expire if, at any date after the Closing
Date, the Purchaser and the Carlyle Affiliates hold less than 5% of the Series B
Preferred Stock originally purchased by the Purchaser.

                                 INDEMNIFICATION 

8.1  SURVIVAL OF REPRESENTATIONS, ETC. 

              The representations and warranties of the parties hereto 
contained herein shall survive the Closing for a period of sixty (60) days 
following receipt by the Purchaser of the audited financial statements of the 
Company for the Fiscal Year ended June 30, 1998, except as to (a) the 
representations and warranties set forth in Sections 4.8, 4.9, 4.13 (to the 
extent related to any Applicable Laws relating to health care, the health 
care industry and the provision of health care services, third party 
reimbursement (including Medicare and Medicaid), public health and safety and 
wrongful death and medical malpractice), 4.16, 4.17, 4.32, 4.33, 4.34, 4.35 
and 4.36 hereof, which shall survive for the period of the statute of 
limitations applicable thereto; (b) any matter as to which a Claim has been 
submitted in writing to the Company prior to such date; and (c) any matter 
based on fraud by the Company in making any of the representations and 
warranties contained in this Agreement. With respect to the matters set forth 
in (b) and (c) above, the cause of action in favor of the Purchaser in 
respect of such matters shall survive indefinitely. 

8.2  INDEMNIFICATION BY THE COMPANY. 

              The Company agrees to indemnify and hold harmless the Purchaser,
its Subsidiaries, its Affiliates, the Carlyle Affiliates and the directors,
officers, employees, stockholders and partners of each of the Purchaser, its
Subsidiaries, its Affiliates and the Carlyle Affiliates (individually, an
"Indemnified Party" and collectively, the "Indemnified Parties"),  from and
against any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs and reasonable attorneys' fees, expenses and
disbursements of any kind ("Losses") which may be imposed upon or incurred by
the Purchaser in any manner relating to or arising out 

                                       60
<PAGE>

of any untrue representation, breach of warranty or failure to perform any 
covenant or agreement by the Company contained in this Agreement (including, 
without limitation, the schedules and exhibits hereto), the Series B 
Certificate of Designation, the Series D Certificate of Designation, the 
Ancillary Agreements or in any certificate or document delivered pursuant 
hereto or thereto or arising out of any Applicable Laws relating to health 
care, the health care industry and the provision of health care services, 
third party reimbursement (including Medicare and Medicaid), public health 
and safety and wrongful death and medical malpractice or otherwise relating 
to or arising out of the Transaction; PROVIDED, HOWEVER, that the Company 
shall provide no indemnification with respect to Losses relating to or 
arising out of the Transaction if such Losses were caused principally by the 
gross negligence or willful misconduct of one or more Indemnified Parties.

8.3  LIMITATION ON INDEMNITIES. 

              No Claim may be made against the Company for indemnification 
pursuant to Section 8.2 until the aggregate dollar amount of all Losses 
indemnifiable pursuant to Section 8.2 exceeds $250,000 (in which event the 
Purchaser shall be entitled to claim the whole amount of such  Losses and not 
merely the excess).  In no event shall the aggregate amount paid by the 
Company pursuant to Section 8.2 exceed $25 million with respect to Claims 
arising out of or related to matters other than breaches of the 
representations, warranties and covenants contained in Sections 4.13 (to the 
extent related to Applicable Laws relating to health care, the health care 
industry and the provision of health care services, third party reimbursement 
(including Medicare and Medicaid), public health and safety and wrongful 
death and medical malpractice), 4.32, 4.33, 4.34, 4.35, 4.36 and 6.9 (to the 
extent related to Applicable Laws relating to health care, the health care 
industry and the provision of health care services, third party reimbursement 
(including Medicare and Medicaid), public health and safety and wrongful 
death and medical malpractice), as to which breaches of the representations, 
warranties and covenants contained in such Sections, there shall be no cap on 
the Company's indemnification obligations under Section 8.2.

8.4  LOSSES. 

              The term "Losses" as used in this Article VIII is not limited 
to matters asserted by third parties but includes Losses incurred or 
sustained by an Indemnified Party in the absence of third party claims.  The 
difference between (a) any insurance proceeds received by an Indemnified 
Party in respect of Losses and (b) the legal costs and expenses incurred by 
such Indemnified Party, if any, in seeking the payment of such insurance 
proceeds from the insurer or insurers who insured against such Loss, shall be 
deducted from any Claim for indemnification made by such Indemnified Party 
against the Company. Payments by an Indemnified Party of amounts for which 
such Indemnified Party is indemnified hereunder shall not be a condition 
precedent to recovery.  If, after payment of any Claim by the Company to an 
Indemnified Party, such Indemnified Party receives insurance proceeds on 
account of the Loss indemnified by such payment by the Company, such 
Indemnified Party shall pay to the Company the lesser of (a) the amount of 
the payment on the Claim with respect to such Loss by the Company to the 
Indemnified Party and (b) the amount of such insurance proceeds minus the 
legal costs and 

                                       61
<PAGE>

expenses incurred by such Indemnified Party, if any, in seeking the payment 
of such insurance proceeds from the insurer or insurers who insured against 
such Loss.

8.5  DEFENSE OF CLAIMS. 

              If a claim for Losses (a "Claim") is to be made by an 
Indemnified Party, such Indemnified Party shall give written notice (a "Claim 
Notice") to the Company as soon as practicable after such Indemnified Party 
becomes aware of any fact, condition or event which may give rise to Losses 
for which indemnification may be sought under this Article VIII.  If any 
lawsuit or enforcement action is filed against any Indemnified Party 
hereunder, notice thereof (a "Third Party Notice") shall be given to the 
Company as promptly as practicable (and in any event within ten (10) calendar 
days after the service of the citation or summons).  The failure of any 
Indemnified Party to give timely notice hereunder shall not affect rights to 
indemnification hereunder, except to the extent that the Company demonstrates 
actual damage caused by such failure. After receipt of a Third Party Notice, 
if the Company shall acknowledge in writing to the Indemnified Party that the 
Company shall be obligated under the terms of its indemnity hereunder in 
connection with such lawsuit or action, then the Company shall be entitled, 
if it so elects, (a) to take control of the defense and investigation of such 
lawsuit or action, (b) to employ and engage attorneys of its own choice to 
handle and defend the same, at the Company's cost, risk and expense unless 
the named parties to such action or proceeding include both the Company and 
the Indemnified Party and the Indemnified Party has been advised in writing 
by counsel that there may be one or more legal defenses available to such 
Indemnified Party that are different from or additional to those available to 
the Company, and (c) to compromise or settle such claim, which compromise or 
settlement (i) shall be made and entered into only with the advance written 
consent of the Indemnified Party (in its sole discretion) if such compromise 
or settlement, in the reasonable judgment of the Indemnified Party, would 
cause more than de minimis harm to such Indemnified Party's business 
reputation, (ii) may be made and entered into in the sole discretion of the 
Company if such compromise or settlement provides for the payment solely of 
cash to the claimant in such lawsuit in full satisfaction of such claimant's 
claim therein and includes a release of the Indemnified Party to the maximum 
extent permitted by law (and would not otherwise, in the reasonable judgment 
of such Indemnified Party, cause more than de minimis harm to such 
Indemnified Party's business reputation) and (iii) otherwise shall be entered 
into only with the advance written consent of the Indemnified Party (such 
consent not to be unreasonably withheld).  The Indemnified Party shall 
cooperate in all reasonable respects with the Company and such attorneys in 
the investigation, trial and defense of such lawsuit or action and any appeal 
arising therefrom; and the Indemnified Party may, at its own cost, 
participate in the investigation, trial and defense of such lawsuit or action 
and any appeal arising therefrom and appoint its own counsel therefor, at its 
own cost.  The parties shall also cooperate with each other in any  
notifications to insurers.  If the Company fails to assume the defense of 
such claim within fifteen (15) calendar days after receipt of the Third Party 
Notice, the Indemnified Party against which such claim has been asserted will 
(upon delivering notice to such effect to the Company) have the right to 
undertake the defense, compromise or settlement of such claim at the 
Company's cost and the Company shall have the right to participate therein at 
its own cost; provided, however, that such claim shall not be compromised or 
settled without the written consent of the Company, which consent shall not 
be unreasonably withheld.  In the event the 

                                       62
<PAGE>

Indemnified Party assumes the defense of the claim, the Indemnified Party 
will keep the Company reasonably informed of the progress of any such 
defense, compromise or settlement.  Notwithstanding the foregoing, the 
Company shall not be liable for the reasonable fees and expenses of more than 
one firm of attorneys at any time for any and all Indemnified Parties (which 
firm shall be designated in writing by such Indemnified Party or Parties) in 
connection with any one such action or proceeding or multiple actions or 
proceedings provided that they are held in the same jurisdiction, arising out 
of the same general allegations or circumstances.

                                   ARTICLE IX
                                  MISCELLANEOUS

9.1  FEES AND EXPENSES. 

              The Company shall be responsible for the payment of all 
expenses incurred by the Company in connection with the Transaction, 
regardless of whether any portion of the Transaction closes, including, 
without limitation, all fees and expenses of the Company's legal counsel and 
all third party consultants engaged by the Company to assist in the 
Transaction.  

9.2  INJUNCTIVE RELIEF. 

              The parties hereto acknowledge and agree that irreparable damage
would occur in the event any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. 
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of the provisions of this Agreement and shall be
entitled to enforce specifically the provisions of this Agreement in any court
of the United States or any state thereof having jurisdiction, in addition to
any other remedy to which the parties may be entitled under this Agreement or at
law or in equity

9.3  ASSIGNMENT. 

              Neither this Agreement nor any of the rights or obligations
hereunder may be assigned by the Company without the prior written consent of
the Purchaser, or by the Purchaser without the prior written consent of the
Company, except that the Purchaser may, without such consent, assign, in whole
or in part, the right to acquire the Securities hereunder to a Carlyle
Affiliate.  Subject to the foregoing, this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, and no other person shall have any right, benefit or obligation
hereunder.

9.4  NOTICES. 

              Unless otherwise provided herein, any notice, request,
instruction or other document to be given hereunder by any party to the other
shall be in writing and delivered by hand-delivery, registered first-class mail,
return receipt requested, facsimile or air courier guaranteeing overnight

and pursuant to the terms of the Series C Certificate of Designation, all of 
the shares of Series C Preferred Stock the Purchaser is to receive at the 
First Closing and the Second Closing pursuant to the terms of this Agreement. 
 The denominator of such quotient shall equal the sum of (1) such numerator, 
plus (2) the number of shares of Common Stock that would need to be issued if 
all of the shares of Series B Preferred Stock to be issued pursuant to the 
Carlyle Purchase Agreement were converted into Common Stock, pursuant to the

issuances of Capital Stock contemplated in clauses (ii), (iii), (iv) and (v) 
of Section 4.2(b) were to occur immediately following the Closing plus (5) 
all shares of Common Stock issued and outstanding on the First Closing Date.  
The calculation in the immediately preceding sentence shall be made as if all 
issuances of Common Stock referred to in clauses (1), (2), (3), (4) and (5) 
thereof were made immediately following the First Closing, whether or not the 
Company is or could be under any obligation to issue such shares of Common

         plan," as defined in Section 607(1) of ERISA, has been operated in
         compliance with provisions of Part 6 of Title I, Subtitle B of ERISA
         and  4980B of the Code at all times.  The Company is not obligated to
         provide health care benefits of any kind to its retired or former
         employees or their dependents pursuant to any agreement or
         understanding.

                   (iv)      BENEFIT ARRANGEMENTS.  Each Benefit Arrangement
     has been maintained in compliance, in all material respects, with its
     terms and with the requirements prescribed by any and all statutes,
     orders, rules and regulations which are applicable to such Benefit
     Arrangement, including without limitation, the Code, and with all plan
     documents.  Except as set forth in SCHEDULE 4.8 and except as provided by
     law, the employment of all persons presently employed or retained by the
     Company is terminable at will.

                   (v)       UNRELATED BUSINESS TAXABLE INCOME.  No Employee
     Plan (or trust or other funding vehicle pursuant thereto) is subject to
     any Tax under Section 511 of the Code.

                   (vi)      DEDUCTIBILITY OF PAYMENTS.  Except as disclosed in
     SCHEDULE 4.8, there is no contract, agreement, plan or arrangement
     covering any present or former employee, director or consultant of the
     Company or any of its ERISA Affiliates (with respect to his or her
     relationship with such entities) that, individually or collectively,
     provides for the payment by the Company of any amount (i) that is not
     deductible under Section 162(a)(l) or 404 of the Code or (ii) that is an
     "excess parachute payment" pursuant to Section 280G of the Code.

                   (vii)     FIDUCIARY DUTIES AND PROHIBITED TRANSACTIONS. 
     Neither the Company nor any plan fiduciary of any Welfare Plan or Pension
     Plan has engaged in any transaction in violation of Sections 404 or 406
     of ERISA or any "prohibited transaction," as defined in Section
     4975(c)(1) of the Code, for which no exemption exists under Section 408
     of ERISA or Section 4975(c)(2) or (d) of the Code, or has otherwise
     violated the provisions of Part 4 of Title I, Subtitle B of ERISA.  The
     Company has not participated in a violation of Part 4 of Title I,
     Subtitle B of ERISA by any plan fiduciary of any Welfare Plan or Pension
     Plan.  The Company has not been assessed any civil penalty under Section
     502(1) of ERISA.

                   (viii)    VALIDITY AND ENFORCEABILITY.  Each Welfare Plan
     related trust agreement, annuity contract or other funding instrument is
     legally valid, binding, enforceable against the Company and in full force
     and effect, except as enforceability may be limited by (i) applicable
     bankruptcy, insolvency, reorganization, moratorium, and similar laws
     affecting creditors' rights generally, and (ii) general equitable
     principles (regardless of whether such enforceability is considered in a
     proceeding in equity or at law).  .

                   (ix)      LITIGATION.  There is no Proceeding relating to or
     seeking benefits under any Employee Plan that is pending, or, to the
     Knowledge of the Company, threatened against the Company, any ERISA
     Affiliate or any Employee Plan other than routine claims for benefits.

                   (x)       NO AMENDMENTS.  Except as disclosed in Schedule
     4.8, neither the Company nor any ERISA Affiliate has any announced plan
     or legally binding commitment to create any additional Employee Plans
     which are intended to cover present or former employees, directors or
     consultants of the Company or any of its ERISA Affiliates (with respect
     to their relationship with such Persons) or to amend or modify any
     existing Employee Plan.  Each Employee Plan can be amended or terminated
     at any time without approval from any Person, without advance notice and
     without any liability other than for benefits accrued prior to such
     amendments or termination.

                   (xi)      NO OTHER MATERIAL LIABILITY.  To the Knowledge of
     the Company, no event has occurred in connection with which the Company
     or any ERISA Affiliate or any Employee Plan, directly or indirectly,
     could be subject to any material liability (A) under any statute,
     regulation or governmental order relating to any Employee Plan or
     (B) pursuant to any obligation of the Company to indemnify any person
     against liability incurred under any such statute, regulation or order as
     they relate to the Employee Plans.

                   (xii)     INSURANCE CONTRACTS.  Neither the Company nor any
     Employee Plan (other than a Multiemployer Plan) holds as an asset of any
     Employee Plan any interest in any annuity contract, guaranteed investment
     contract or any other investment or insurance contract issued by an
     insurance company that is the subject of bankruptcy, conservatorship or
     rehabilitation proceedings.

                   (xiii)    NO ACCELERATION OR CREATION OF RIGHTS.  Except as
     disclosed on Schedule 4.8, neither the execution and delivery of this
     Agreement by the Company nor the consummation of all or any portion of
     the Transaction will result in the acceleration or creation of any rights
     of any person to benefits under any Employee Plan (including, without
     limitation, the acceleration of the vesting or exercisability of any
     stock options, the acceleration of the vesting of any restricted stock,
     the acceleration of the accrual or vesting of any benefits under any
     Pension Plan or the acceleration or creation of any rights under any
     severance, parachute or change in control agreement).

              (c)  There are no employment, consulting, change of control,
severance pay, continuation pay, termination pay, loans, guarantees or
indemnification agreements or other 

                                       25
<PAGE>

similar agreements of any nature whatsoever (collectively, "Employment 
Agreements") between the  Company, on the one hand, and any current or former 
stockholder, officer, director, employee or Affiliate of the Company or any 
consultant or agent of the Company, on the other hand, that, as a direct 
result of the Transaction, (i) will require any payment by the Company or any 
consent or waiver from any stockholder, officer, director, employee or 
Affiliate of the Company or any consultant or agent of the Company, or (ii) 
will result in any change in the nature of any rights of any stockholder, 
officer, director, employee or Affiliate of the Company or any consultant or 
agent of the Company under any such Employment Agreement or other similar 
agreement (including, without limitation, any accelerated payments, deemed 
satisfaction of goals or conditions, new or increased benefits or additional 
or accelerated vesting).

4.9  GOVERNMENTAL FILINGS. 

              (a)  Since June 30, 1994, the Company and each of its 
Subsidiaries have filed with the Commission all forms, reports, schedules, 
statements and other documents required to be filed by them under the 
Securities Act, the Exchange Act and all other federal securities laws and 
the rules and regulations promulgated thereunder (the "SEC Filings").  Each 
SEC Filing was prepared in accordance with, and at the time of filing 
complied in all material respects with, the requirements of the Securities 
Act, the Exchange Act or other applicable federal securities law and the 
rules and regulations promulgated thereunder, as the case may be, except as 
the same was corrected or superseded in an amendment to such SEC Filing filed 
with the Commission.  None of the SEC Filings, including, without limitation, 
any financial statements or schedules included therein, at the time filed, 
contained any untrue statement of a material fact or omitted to state any 
material fact required to be stated therein or necessary in order to make the 
statements contained therein, in light of the circumstances under which they 
were made, not misleading, except as the same was corrected or superseded in 
a subsequent document duly filed with the Commission.  The Company has 
heretofore furnished or made available to the Purchaser true, correct and 
complete copies of all SEC Filings since June 30, 1996. 

              (b)  Since June 30, 1992, all material reports, documents and 
notices required to be filed, maintained or furnished to any Governmental 
Entity (other than the Commission) by the Company or any Subsidiary have been 
so filed, maintained or furnished.  All such reports, documents and notices 
were complete and correct in all material respects on the date filed (or were 
corrected in or superseded by a subsequent filing) such that no Liabilities 
exist with respect to such filing.  

4.10 FINANCIAL STATEMENTS AND REPORTS.   

              (a)  The financial statements contained in the SEC Filings
(collectively, the "Financial Statements") have been prepared in accordance with
GAAP applied on a consistent basis throughout the periods indicated and with
each other (except that the Financial Statements may not contain all footnotes
required by GAAP) and fairly present the consolidated financial condition of the
Company and the Subsidiaries and the consolidated results of operations as of
such dates and for such periods indicated.  Since April 30, 1997, there has not
been any change to the financial condition of the Company or any Subsidiary as

as reflected in the Financial Statements, neither the Company nor any 
Subsidiary is a guarantor or indemnitor of any Indebtedness of any other 
Person.  The Company maintains a standard system of accounting established 
and administered in accordance with GAAP.  The general ledger, accounts 
receivable, accounts payable, bank reconciliations and payroll records of the 
Company have been maintained in all material respects in the ordinary course 
and contain a materially correct and complete record of the matters typically 
contained in records of such nature.

              (b)  The Company has not received any management letters or 
other letters (other than audit letters included in the SEC Filings) from the 
Company's independent auditing firm(s) relating to the results of operations, 
financial statements or internal controls of the Company or any Subsidiary 
insofar as the same may pertain to the business or assets of the Company and 
any Subsidiary during any period from and after June 30, 1994.

nor any Subsidiary is a party to (i) any Material Agreement relating to the 
making of any advance to, or investment in, any Person, or (ii) any Material

except for directors' fees, travel expense advances and employment 
compensation to officers; or (xvi) incurred or suffered any other event or

4.13 COMPLIANCE WITH LAWS. 

              (a)  The Company and its Subsidiaries are in compliance in all 
material respects with all material Applicable Laws.  Material Applicable 
Laws includes, without limitation, all Applicable Laws relating to health 
care, the health care industry and the provision of health care services, 
third party reimbursement (including Medicare and Medicaid), public health 
and safety and wrongful death and medical malpractice.  Neither the Company 
nor any of its Subsidiaries has received any notice of, nor does the Company 
or any of its Subsidiaries have any Knowledge of, any violation (or of any 
investigation, inspection, audit or other proceeding by any Governmental 
Entity involving allegations of any violation) of any Applicable Law 
involving or related to the Company or any of its Subsidiaries which has not 
been dismissed or otherwise disposed of.  Except as set forth in SCHEDULE 
4.13(A), neither the Company nor any of its Subsidiaries has received notice 
or otherwise has any Knowledge that the Company or any Subsidiary is charged 
with, threatened with or under investigation with respect to, any violation 
of any Applicable Law, or has any Knowledge of any proposed change in any 
Applicable Law that would have a Material Adverse Effect on the Transaction 
or the Company.

              (b)  Each of the Company and its Subsidiaries has, and all
professional employees or agents of each of the Company and its Subsidiaries who
are performing health care or health care related functions on behalf of the
Company or any of its Subsidiaries or joint ventures have, all material
licenses, franchises, permits, accreditations, provider numbers, authorizations,
including certificates of need, consents or orders of, or filings with, or other

                                       28
<PAGE>

approvals from all Governmental Entities ("Approvals") necessary for the 
conduct of, or relating to the operation of, the business of each of the 
Company and its Subsidiaries and the occupancy and operation, for its present 
uses, of the real and personal property which each of the Company  and its 
Subsidiaries owns or leases, and neither the Company nor any Subsidiary or 
the professional employees or agents of either (acting in such capacities) is 
in violation of any such Approval in any material respect or any terms or 
conditions thereof.  All such Approvals are in full force and effect, have 
been issued to and fully paid for by the holder thereof and no notice or 
warning from any Governmental Entity with respect to the suspension, 
revocation or termination of any Approval has been, to the Knowledge of the 
Company, threatened by any Governmental Entity or issued or given to the 
Company or any Subsidiary.  No such Approvals will in any way be affected by, 
terminate or lapse by reason of the consummation of all or any portion of the 
Transaction.  There are no physicians (other than radiologists and radiation

of the Company acquired on terms equally available to the public through 
trading on the Nasdaq Stock Market, and no physician owns 5% or more of the 
outstanding shares of any class of securities issued by the Company.

4.14 LITIGATION.  

              Except as set forth on SCHEDULE 4.14 hereto, there is no 
Proceeding (by any Governmental Entity or otherwise) of which the Company has 
received notice or of which the Company has Knowledge pending against or 
affecting the Company, any Subsidiary or the assets, products or business of 
any of them or, to the Knowledge of the Company, any basis therefor or threat 
thereof.  Except as set forth on SCHEDULE 4.14 hereto, neither the Company 
nor any Subsidiary is a party or subject to the provisions of any order, 
writ, injunction, judgment or decree of any court or other Governmental 
Entity. Except as set forth on SCHEDULE 4.14 hereto, there is no Proceeding 
by the Company or any Subsidiary currently pending or that the Company or any 
Subsidiary currently intends to initiate.  There are no Proceedings pending 
or, to the Knowledge of the Company, threatened against the Company, any 
Subsidiary or any of their respective businesses, assets or products that 
seek to enjoin, question the validity of or rescind the Transaction, the 
Carlyle Purchase Agreement, the Ancillary Agreements or otherwise prevent the 
Company from complying with the terms and provisions of this Agreement, the 
Carlyle Purchase Agreement, the Ancillary Agreements or any of such other 
agreements.  Any and all Liabilities of the Company and its Subsidiaries 
under such Proceedings that are probable and subject to reasonable estimation 
within the meaning of GAAP are adequately covered (except for standard 
deductible amounts) by the existing insurance maintained by the Company or 
estimates in accordance with GAAP for the uninsured costs thereof are 
reflected in the Financial Statements.  No holder of shares of the Capital 
Stock of American Health Services Corp. or Maxum Health Corp. (constituent 
corporations in the mergers contemplated by the Merger Agreement) that either 
were outstanding immediately prior to such mergers made a demand for the 
appraisal of such holder's shares pursuant to Section 262 of the Delaware 
General Corporation Law.

              (f)  None of the Company and its Subsidiaries (i) has been a
member of any affiliated group filing a consolidated federal income Tax Return
(other than a group the common parent of which is the Company) or (ii) has any

Subsidiaries) under Treas. Reg. Section  1.1502-6 (or any similar provision of
state, local or foreign law), as a transferee or successor, by contract or
otherwise.

              (g)  The charges, accruals and reserves for Taxes (including 
deferred Taxes) currently reflected on the Financial Statements in accordance 
with GAAP are adequate to cover all unpaid Taxes accruing or payable by the 
Company and its Subsidiaries in respect of taxable periods that end on or 
before the Closing Date and for any taxable periods that begin before the 
Closing Date and end thereafter to the extent such Taxes are attributable to 
the portion of such period ending on the Closing Date. 

              (h)  Neither the Company nor any Subsidiary has agreed, 
requested or been requested to make, or is required to make, any adjustment 
to taxable income for any taxable period after the Closing under Sections 
481(a) or 263A of the Code or any comparable provision of state or foreign 
tax laws by reasons of a change in accounting method or otherwise.

              (i)  There are no Encumbrances (other than Permitted 
Encumbrances) on any asset or property of the Company or any Subsidiary

international sales corporation (or "DISC") within the meaning of Section 992 
of the Code.

              (l)  Other than the elections made in the Tax Returns provided

into by the Company or any Subsidiary.  No consent has been filed with 
respect to the Company or any Subsidiary under Section 341(f) of the Code.

              (m)  SCHEDULE 4.16 lists all federal, state, local and foreign 
Tax Returns that have been audited, and indicates those Tax Returns that 
currently are the subject of audit, other than (i) Tax Returns relating to 
closed years, and (ii) Tax Returns that have been audited where such audit 
did not result in any change in any tax due from the Company or any 
Subsidiary to any Governmental Entity.  Correct and complete copies of all 
federal Tax Returns, examination reports and statements of deficiencies 
assessed against or agreed to by the Company or any of its Subsidiaries since 
June 30, 1996 have been delivered or made available to the Purchaser.  Each 
of the Company and its Subsidiaries has disclosed on its federal income Tax 
Returns all positions taken therein that could reasonably be expected to give 
rise to a substantial understatement of federal income Tax within the meaning 
of Section 6662 of the Code.

of its authorized but unissued shares of Common Stock and preferred stock, 
par value $.001 per share, solely for the purpose of effecting the conversion 
of shares of Series B Preferred Stock and Series C Preferred Stock and the 
issuance of Common Stock in respect of the Warrants and the Carlyle Warrants, 
the full number of whole shares of Common Stock and Series D Preferred Stock 
then deliverable upon (a) the conversion of all shares of Series B Preferred 
Stock and Series C Preferred Stock then outstanding, (b) the issuance of 
Common Stock in respect of the Warrants and the Carlyle Warrants, and (c) if 
any Series D Preferred Stock is then outstanding, the full number of whole 
shares of Common Stock then deliverable upon the conversion of all shares of

may validly and legally issue fully paid and non-assessable shares of Common 
Stock or Series D Preferred Stock (as the case may be) upon the conversion of 
shares of Series B Preferred Stock, Series C Preferred Stock, and Series D 
Preferred Stock and the exercise of the then outstanding Warrants and Carlyle 
Warrants.  If at any time the number of authorized but unissued shares of 
Common Stock or Series D Preferred Stock shall not be sufficient to effect 
the conversion of all then outstanding shares of the Series B Preferred 
Stock, Series C Preferred Stock, and Series D Preferred Stock and the 
exercise of all the then outstanding Warrants and Carlyle Warrants, in 
addition to such other remedies as shall be available to the holders of the 
Series B Preferred Stock, Series C Preferred Stock, and Series D Preferred 
Stock, the Company shall forthwith take such corporate action as may be 
necessary to  increase its authorized but unissued shares of Common Stock or 
Series D Preferred Stock to such numbers of shares as shall be sufficient for 
such purpose, including but not limited to promptly calling and holding a 
meeting of the Company's stockholders, at which the Company's stockholders 
shall vote on a proposed amendment to the Certificate of Incorporation that 
would so increase the number of authorized shares of Common Stock or 
preferred stock, par value $.001 per share, as appropriate, a favorable vote 
for which amendment shall have been recommended to the Company's stockholders 
by the Board of Directors, pursuant to a duly and 

                                       47
<PAGE>

validly adopted resolution of the Board of Directors setting forth the 
amendment proposed and declaring its advisability, all in accordance with 
Section 242 of the Delaware General Corporation Law; and, in case of an 
increase in the number of authorized shares, of such preferred stock, the 
Board of Directors shall promptly cause to become effective a certificate of 
increase pursuant to Section 151 of the Delaware General Corporation Law.

participation in third party payment programs, including, without limitation, 
preparation and submission of claims for reimbursement.  Nothing in this 
Section 6.9 shall be construed as or is intended to create any third party 
beneficiaries.

              (a)  The Company will keep in effect following the First 
Closing the employment agreements with the employees set forth in SCHEDULE 
4.23, on the same terms and conditions contained in such employment 
agreements prior to the First Closing Date; provided, however, that such 
employment agreements shall be modified so that none of (i) the Transaction, 
(ii) any conversion of Series B Preferred Stock or Series C Preferred Stock 
acquired hereunder or under the GE Purchase Agreement into shares of Series D 
Preferred Stock or Common Stock , (iii) any conversion of shares of Series D 
Preferred Stock into Common Stock, or (iv) any change in the membership, size 
or composition of the Board of Directors incident to the transaction or such 
conversions, shall trigger or constitute a change of control or otherwise 
give any party to such employment agreements any right to receive any payment 
(or any acceleration thereof) or protections whatsoever.

              (b)  Following the First Closing, the Company and the Purchaser 
will review the terms and conditions of the bonus plan currently in effect at 
the Company to determine whether any changes should be made to such bonus

ordinary course of business and pursuant to the reasonable requirements of 
the Company's or such Subsidiary's business and upon fair and reasonable

transaction at the time from a Person which is not such an Affiliate.

industry and the provision of health care services, third party reimbursement
(including Medicare and Medicaid), public health and safety and wrongful death
and medical malpractice), 4.16, 4.17, 4.32, 4.33, 4.34, 4.35 and 4.36 hereof,

8.2   INDEMNIFICATION BY THE COMPANY. 

               The Company agrees to indemnify and hold harmless the Purchaser,
its Subsidiaries, and its Affiliates and the directors, officers, employees,
stockholders and partners of each of the Purchaser, its Subsidiaries, and its
Affiliates (individually, an "Indemnified Party" and collectively, the
"Indemnified Parties"), from and against any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs and reasonable
attorneys' fees, expenses and disbursements of any kind ("Losses") which may be
imposed upon or incurred by the Purchaser in any manner relating to or arising
out of any untrue representation, breach of warranty or failure to perform any
covenant or agreement by the Company contained in this Agreement (including,
without limitation, the schedules and exhibits hereto), the Series C Certificate
of Designation, the Series D Certificate of Designation, the Ancillary
Agreements or in any certificate or document delivered pursuant hereto or
thereto or arising out of any Applicable Laws relating to health care, the
health care industry and the provision of health care services, third party
reimbursement (including Medicare and Medicaid), public health and safety and
wrongful death and medical malpractice or otherwise relating to or arising out
of the Transaction; PROVIDED, HOWEVER, that the Company shall provide no
indemnification with respect to Losses relating to or arising out of the
Transaction if such Losses were caused principally by the gross negligence or
willful misconduct of one or more Indemnified Parties.

8.3   LIMITATION ON INDEMNITIES. 

               No Claim may be made against the Company for indemnification
pursuant to Section 8.2 until the aggregate dollar amount of all Losses
indemnifiable pursuant to Section 8.2 exceeds $250,000 (in which event the
Purchaser shall be entitled to claim the whole amount of such Losses and not
merely the excess).  In no event shall the aggregate amount paid by the Company
pursuant to Section 8.2 exceed $25 million with respect to Claims arising out of
or related to matters other than breaches of the representations, warranties and
covenants contained in Sections 4.13 (to the extent related to Applicable Laws
relating to health care, the health care industry and the provision of health
care services, third party reimbursement (including Medicare and Medicaid),
public health and safety and wrongful death and medical malpractice), 4.32,
4.33, 4.34, 4.35, 4.36 and 6.9 (to the extent related to Applicable Laws
relating to health care, the health care industry and the provision of health
care services, third party reimbursement (including Medicare and Medicaid),
public health and safety and wrongful death and medical malpractice), as to
which breaches of the representations, warranties and covenants contained in
such Sections, there shall be no cap on the Company's indemnification
obligations under Section 8.2.

8.4   LOSSES. 

               The term "Losses" as used in this Article VIII is not limited to
matters asserted by third parties but includes Losses incurred or sustained by
an Indemnified Party in the absence of third party claims.  The difference
between (a) any insurance proceeds received by an Indemnified Party in respect
of Losses and (b) the legal costs and expenses incurred by such Indemnified
Party, if any, in seeking the payment of such insurance proceeds from the
insurer or

                                        62

<PAGE>

insurers who insured against such Loss, shall be deducted from any
Claim for indemnification made by such Indemnified Party against the Company. 
Payments by an Indemnified Party of amounts for which such Indemnified Party is
indemnified hereunder shall not be a condition precedent to recovery.  If, after
payment of any Claim by the Company to an Indemnified Party, such Indemnified
Party receives insurance proceeds on account of the Loss indemnified by such
payment by the Company, such Indemnified Party  shall pay to the Company the
lesser of (a) the amount of the payment on the Claim with respect to such Loss
by the Company to the Indemnified Party and (b) the amount of such insurance
proceeds minus the legal costs and expenses incurred by such Indemnified Party,
if any, in seeking the payment of such insurance proceeds from the insurer or
insurers who insured against such Loss.

8.5   DEFENSE OF CLAIMS. 

               If a claim for Losses (a "Claim") is to be made by an Indemnified
Party, such Indemnified Party shall give written notice (a "Claim Notice") to
the Company as soon as practicable after such Indemnified Party becomes aware of
any fact, condition or event which may give rise to Losses for which
indemnification may be sought under this Article VIII.  If any lawsuit or
enforcement action is filed against any Indemnified Party hereunder, notice
thereof (a "Third Party Notice") shall be given to the Company as promptly as
practicable (and in any event within ten (10) calendar days after the service of
the citation or summons).  The failure of any Indemnified Party to give timely
notice hereunder shall not affect rights to indemnification hereunder, except to
the extent that the Company demonstrates actual damage caused by such failure. 
After receipt of a Third Party Notice, if the Company shall acknowledge in
writing to the Indemnified Party that the Company shall be obligated under the
terms of its indemnity hereunder in connection with such lawsuit or action, then
the Company shall be entitled, if it so elects, (a) to take control of the
defense and investigation of such lawsuit or action, (b) to employ and engage
attorneys of its own choice to handle and defend the same, at the Company's
cost, risk and expense unless the named parties to such action or proceeding
include both the Company and the Indemnified Party and the Indemnified Party has
been advised in writing by counsel that there may be one or more legal defenses
available to such Indemnified Party that are different from or additional to
those available to the Company, and (c) to compromise or settle such claim,
which compromise or settlement (i) shall be made and entered into only with the
advance written consent of the Indemnified Party (in its sole discretion) if
such compromise or settlement, in the reasonable judgment of the Indemnified
Party, would cause more than de minimis harm to such Indemnified Party's
business reputation, (ii) may be made and entered into in the sole discretion of
the Company if such compromise or settlement provides for the payment solely of
cash to the claimant in such lawsuit in full satisfaction of such claimant's
claim therein and includes a release of the Indemnified Party to the maximum
extent permitted by law (and would not otherwise, in the reasonable judgment of
such Indemnified Party, cause more than de minimis harm to such Indemnified
Party's business reputation) and (iii) otherwise shall be entered into only with
the advance written consent of the Indemnified Party (such consent not to be
unreasonably withheld).  The Indemnified Party shall cooperate in all reasonable
respects with the Company and such attorneys in the investigation, trial and
defense of such lawsuit or action and any appeal arising therefrom; and the
Indemnified Party may, at its own cost, participate in the investigation, trial
and defense of such lawsuit or action and any appeal arising therefrom and

                                        63

<PAGE>

appoint its own counsel therefor, at its own cost.  The parties shall also
cooperate with each other in any notifications to insurers.  If the Company
fails to assume the defense of such claim within fifteen (15) calendar days
after receipt of the Third Party Notice, the Indemnified Party against which
such claim has been asserted will (upon delivering notice to such effect to the
Company) have the right to undertake the defense, compromise or settlement of
such claim at the Company's cost and the Company shall have the right to
participate therein at its own cost; provided, however, that such claim shall
not be compromised or settled without the written consent of the Company, which
consent shall not be unreasonably withheld.  In the event the Indemnified Party
assumes the defense of the claim, the Indemnified Party will keep the Company
reasonably informed of the progress of any such defense, compromise or
settlement.  Notwithstanding the foregoing, the Company shall not be liable for
the reasonable fees and expenses of more than one firm of attorneys at any time
for any and all Indemnified Parties (which firm shall be designated in writing
by such Indemnified Party or Parties) in connection with any one such action or
proceeding or multiple actions or proceedings provided that they are held in the
same jurisdiction, arising out of the same general allegations or circumstances.

                                ARTICLE IX
                               MISCELLANEOUS

9.1   FEES AND EXPENSES. 

               The Company shall be responsible for the payment of all expenses
incurred by the Company in connection with the Transaction, regardless of
whether any portion of the Transaction closes, including, without limitation,
all fees and expenses of the Company's legal counsel and all third party
consultants engaged by the Company to assist in the Transaction.  

9.2   INJUNCTIVE RELIEF. 

               The parties hereto acknowledge and agree that irreparable damage
would occur in the event any of the provisions of this Agreement were not
performed in accordance with their specific  terms or were otherwise breached. 
It is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of the provisions of this Agreement and shall be
entitled to enforce specifically the provisions of this Agreement in any court
of the United States or any state thereof having jurisdiction, in addition to
any other remedy to which the parties may be entitled under this Agreement or at
law or in equity

9.3   ASSIGNMENT. 

               Neither this Agreement nor any of the rights or obligations
hereunder may be assigned by the Company without the prior written consent of
the Purchaser, or by the Purchaser without the prior written consent of the
Company, except that the Purchaser may, without such consent, assign, in whole
or in part, the right to acquire the Securities hereunder to an Affiliate of the
Purchaser.  Subject to the foregoing, this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, and no other person shall have any right, benefit or obligation
hereunder.

            The Investors (on behalf of themselves and all permitted 
assignees who are Holders of Registrable Securities) may request at any time 
that the Company file a Registration Statement under the Securities Act on an 
appropriate form (which form shall be available for the sale of the 
Registrable Securities in accordance with the intended method or methods of 
distribution thereof and shall include all financial statements required by 
the SEC to be filed herewith) covering the shares of Registrable Securities 
that are the subject of such request.

       (b)  NUMBER OF DEMAND REGISTRATIONS; REQUIRED THRESHOLD.

            The Company shall be obligated to prepare, file and cause to 
become effective pursuant to this Section 2 no more than two (2) Registration 
Statements in the aggregate for the Investors (on behalf of themselves and 
all permitted assignees who are Holders of Registrable Securities); provided, 
however, that a Registration Statement shall not be counted as one of the two 
(2) Demand Registrations hereunder unless it becomes effective and is 
maintained effective in accordance with the requirements specified in Section 
5(a).  The Company shall not be obligated to prepare, file and cause to 
become effective pursuant to this Section 2 a Registration Statement unless 
the proposed aggregate public offering price of the Registrable Securities to 
be included in such Demand Registration is at least $5 million.

       (c)  DEFERRAL BY COMPANY.

            Notwithstanding anything in this Section 2 to the contrary, the 
Company shall not be obligated to prepare, file and cause to become effective 
pursuant to this Section 2 a Registration Statement if the Company furnishes 
the Investors a certificate signed by the President of the Company that in 
the good faith judgment of the Board of Directors it would be detrimental in 
any material respect to the Company and its shareholders for the Company to 
comply with the Demand Registration, and it is therefore essential to defer 
the filing of the Registration Statement relating thereto.  Any such deferral 
shall be for a period of not more than six (6) months after the Company's 
receipt of the Investor's written request for registration pursuant to this 
Section 2; PROVIDED, HOWEVER, that the Company may not exercise this right 
more than once with respect to a Demand Registration and that any requested 
registration deferred, and not ultimately effected, by the Company pursuant 
to the provisions of this Section 2(c) shall thereafter not be deemed to be a 
requested registration for purposes of the limitation to two (2) Demand 
Registrations pursuant to Section 2(a) above.

                                       5

       (d)  PARTICIPATION.

            The Company shall promptly give written notice to all Holders of 
Registrable Securities and to GE upon receipt of a request for a Demand 
Registration pursuant to Section 2(a) above.  GE may, by written notice to 
the Company and the Investors, within thirty (30) business days of the 
Company's notice, elect to join in a request for a Demand Registration 
pursuant to Section 2(a) above, with respect to a number of shares of GE 
Registrable Securities that is less than or equal to the number of shares of 
Registrable Securities requested to be registered in such Demand Registration 
by the Investors.  The GE Registrable Securities being offered by GE in such 
Demand Registration shall be treated pari passu with the Registrable 
Securities being offered by the Investors for all purposes including 
"underwriter's cutbacks" under subsection (e) of this Section and any such 
request by GE shall not be treated as either a request for "piggyback" rights 
under Section 3 hereof or be treated as the exercise of a demand registration 
right by GE under the GE Registration Rights Agreement.  In addition, the 
Company shall include in such Demand Registration such shares of Registrable 
Securities for which it has received written requests to register such shares 
within thirty (30) days after such written notice has been given.

       (e)  UNDERWRITER'S CUTBACK.

            If the public offering of Registrable Securities and/or GE 
Registrable Securities is to be underwritten and, in the good faith judgment 
of the managing underwriter, the inclusion of all the Registrable Securities 
and/or GE Registrable Securities requested to be registered hereunder would 
interfere with the successful marketing of a smaller number of such shares of 
Registrable Securities and/or GE Registrable Securities, the number of shares 
of Registrable Securities and/or GE Registrable Securities to be included 
shall be reduced to such smaller number with the participation in such 
offering to be pro rata among the Holders of Registrable Securities and/or GE 
Registrable Securities requesting such registration, based upon the number of 
shares of Registrable Securities and/or GE Registrable Securities owned by 
such Holders.

            Any shares that are thereby excluded from the offering shall be 
withheld from the market by the Holders thereof for a period (not to exceed 
thirty (30) days prior to the effective date and one hundred twenty (120) 
days thereafter) that the managing underwriter reasonably determines is 
reasonably necessary in order to successfully market the securities  to be 
offered in the Underwritten Offering.

            The Company and, subject to the requirements of Section 11 
hereof, other Holders of securities of the Company may include such 
securities in such Registration if, but only if, the managing underwriter 
concludes that such inclusion will not interfere with the successful 
marketing of all the Registrable Securities requested to be included in such 
registration.

       (f)  MANAGING UNDERWRITER.

            The managing underwriter or underwriters of any Underwritten 
Offering covered by a Demand Registration shall be selected by Investors 
participating in the Underwritten Offering owning a majority of the shares of 
Common Stock to be offered therein, subject to the 

                                       6
<PAGE>

approval of the Board of Directors (by a majority of the Directors not 
elected by the holders of the Preferred Stock and the Series C Preferred 
Stock), which approval shall not be unreasonably withheld.

3.   PIGGYBACK REGISTRATIONS

       (a)  PARTICIPATION.

            Each time the Company decides to file a Registration Statement 
under the Securities Act (other than registrations on Forms S-4 or S-8 or any 
successor form thereto, and other than a Demand Registration) covering the 
offer and sale by it or any of its security holders of any of its securities 
for money, the Company shall give written notice thereof to all Holders of 
Registrable Securities.  The Company shall include in such Registration 
Statement such shares of Registrable Securities for which it has received 
written requests to register such shares within twenty (20) days after such 
written notice has been given.  If the Registration Statement is to cover an 
Underwritten Offering, such Registrable Securities shall be included in the 
underwriting on the same terms and conditions as the securities otherwise 
being sold through the underwriters.

       (b)  UNDERWRITER'S CUTBACK.

            Subject to the requirements of Section 11 hereof, if in the good 
faith judgment of the managing underwriter of such offering the inclusion of 
all of the shares of Registrable Securities and any other Common Stock 
requested to be registered would interfere with the successful marketing of a 
smaller number of such shares, then the number of shares of Registrable 
Securities and other Common Stock to be included in the offering shall be 
reduced to such smaller number with the participation in such offering to be 
in the following order of priority:  (1) first, the shares of Common Stock 
which the Company proposes to sell for its own account, (2) second, the 
shares of Registrable Securities of all Holders of Registrable Securities 
requested to be included, PARI PASSU with all shares of GE Registrable 
Securities requested by GE to be included and all shares of any Person 
granted "piggyback" registration rights by the Company prior to the date 
hereof with respect to the Company's securities, as set forth in Schedule A 
attached hereto, requested by such Person to be included, and (3) third, any 
other shares of Common Stock requested to be included.  Any necessary 
allocation among the Holders of shares within each of the foregoing groups 
shall be pro rata among such Holders requesting such registration based upon 
the number of shares of Common Stock and Registrable Securities owned by such 
Holders.

            All shares so excluded from the Underwritten Offering shall be 
withheld from the market by the Holders thereof for a period (not to exceed 
thirty (30) days prior to the effective date and one hundred twenty (120) 
days thereafter) that the managing underwriter reasonably determines is 
reasonably necessary in order to successfully market the securities  to be 
offered in the Underwritten Offering.

                                       7
<PAGE>


       (c)  COMPANY CONTROL.

            The Company may decline to file a Registration Statement after 
giving notice to Holders pursuant to Section 3(a) above, or withdraw a 
Registration Statement after filing and after such notice, but prior to the 
effectiveness thereof; provided that the Company shall promptly notify each 
Holder of Registrable Securities in writing of any such action and provided 
further that the Company shall bear all expenses incurred by each Holder or 
otherwise in connection with such withdrawn Registration Statement.

4.   HOLD-BACK AGREEMENTS

       (a)  BY HOLDERS OF REGISTRABLE SECURITIES

            Upon the written request of the managing underwriter of any 
Underwritten Offering of the Company's securities, a Holder of Registrable 
Securities shall not sell, make any short sale of, loan, grant any option for 
the purchase of, or otherwise dispose of any Registrable Securities (other 
than those included in such registration) without the prior written consent 
of such managing underwriter for a period (not to exceed thirty (30) days 
before the effective date and one hundred twenty (120) days thereafter) that 
such managing underwriter reasonably determines is necessary in order to 
effect the Underwritten Offering; provided that each of the officers and 
directors of the Company shall have entered into substantially similar 
holdback agreements with such managing underwriter covering at least the same 
period.

       (b)  BY THE COMPANY AND OTHERS.

            The Company agrees:

               (1)  not to effect any public or private sale or distribution of
     its Equity Securities during the 30-day period prior to, and during the 
     60-day period after, the effective date of each Underwritten Offering made
     pursuant to a Demand Registration or a Piggyback Registration, if so
     requested in writing by the managing underwriter (except as part of such
     Underwritten Offering, pursuant to registrations on Forms S-4 or S-8 or any
     successor forms thereto or private issuances of Equity Securities as
     consideration for any acquisition by the Company or a subsidiary of assets
     or capital stock of any unaffiliated third party), and

               (2)  not to issue any Equity Securities other than for sale in a
     registered public offering unless each of the Persons to which such
     securities are issued has entered a written agreement binding on its
     transferees not to effect any public sale or distribution of such
     securities (except for employee stock options issued to Persons other than:
     directors or officers; or shareholders owning five percent (5%) or more of
     the Company's Equity Securities) during such period, including without
     limitation a sale pursuant to Rule 144 under the Securities Act (except as
     part of such Underwritten Registration, if and to the extent permitted
     hereunder).

5.   REGISTRATION PROCEDURES

            If and whenever the Company is required to register Registrable 
Securities in a Demand Registration,, the Company will use all commercially 
reasonable efforts to effect such registration to permit the sale of such 
Registrable Securities in accordance with the intended plan of distribution 
thereof.  With respect to both Demand Registrations and Piggyback 
Registrations (except as otherwise specifically provided), the Company will 
as expeditiously as practicable:

            (a)  prepare and file with the SEC as soon as practicable a 
Registration Statement with respect to such Registrable Securities and use 
all commercially reasonable efforts to cause such Registration Statement to

earlier to occur of (i) the date six months from the date such Registration 
Statement was declared effective, and (ii) the date the last of the 
Registrable Securities covered by such Registration Statement have been sold, 
provided that before filing a Registration Statement or Prospectus or any 
amendments or supplements thereto, the Company shall furnish to Holders of 
Registrable Securities covered by such Registration Statement and the 
underwriters, if any, draft copies of all such documents proposed to be 
filed, which documents will be subject to the review of such Investor and 
underwriters, and the Company shall not file any Registration Statement or 
amendment thereto or any Prospectus or any supplement thereto to which the 
Investor or the underwriters, if any, shall reasonably object;

            (b)  prepare and file with the SEC such amendments and 
post-effective amendments to the Registration Statement, and such supplements 
to the Prospectus, as may be requested by any underwriter of Registrable 
Securities or as may be required by the rules, regulations or instructions 
applicable to the registration form used by the Company or by the Securities 
Act or rules and regulations thereunder to keep the Registration Statement 
effective until all Registrable Securities covered by such Registration 
Statement are sold in accordance with the intended plan of distribution set 
forth in such Registration Statement or supplement to the Prospectus;

            (c)  promptly notify the selling Holders of Registrable 
Securities and the managing underwriter, if any, and (if requested by any 
such Person) confirm such advice in writing,

                 (1)  when the Prospectus or any supplement or post-effective
     amendment has been filed, and, with respect to the Registration Statement
     or any post-effective amendment, when the same has become effective,

     the Registration Statement or the Prospectus or for additional information,

     the effectiveness of the Registration Statement or the initiation of any

     Company contemplated by clause (1) of paragraph (o) below cease to be 
     accurate  in all material respects,

               (5)  of the receipt by the Company of any notification with 
     respect to the suspension of the qualification of the Registrable 
     Securities for sale in any jurisdiction or the initiation or threatening 
     of any proceeding for such purpose, and

Securities, including, without limitation, information with respect to the 
number of shares of Registrable Securities being sold to underwriters, the 
purchase price being paid therefor by such underwriters and with respect to 
any other terms of the Underwritten Offering of the Registrable Securities to 
be sold in such offering; and make all required filings of such supplement or 
post-effective amendment as soon as notified of the matters to be

and the underwriters, if any, in connection with the offering and sale of the 
Registrable Securities covered by such Prospectus (or preliminary 
prospectus));

          (i)  prior to any public offering of Registrable Securities, use 
all commercially reasonable efforts to register or qualify or cooperate with 
the selling Holders of Registrable Securities, the underwriters, if any, and 
their respective counsel in connection with the registration or qualification 
of such Registrable Securities for offer and sale under the securities or 
blue sky laws of such jurisdictions as such Investor or underwriters may 
designate in writing and do anything else necessary or advisable to enable 
from a legal perspective the disposition in such jurisdictions of the 
Registrable Securities covered by the Registration Statement; provided that 
the Company shall not be required to qualify generally to do business in any 
jurisdiction where it is not then so qualified or to take any action which 
would subject it to general service of process in any such jurisdiction where 
it is not then so subject;

          (j)  cooperate with the selling Holders of Registrable Securities 
and the managing underwriter, if any, to facilitate the timely preparation

the Registrable Securities to be sold and cause such Registrable Securities 
to be in such denominations and registered in such names as the managing 
underwriter may request at least three business days prior to any sale of 
Registrable Securities to the underwriters;

          (k)  use all commercially reasonable efforts to cause the 
Registrable Securities covered by the Registration Statement to be registered 
with or approved by such other governmental agencies or authorities as may be 
necessary to enable the seller or sellers thereof or the underwriters, if 
any, to consummate the disposition of such Registrable Securities;

          (l)  if the Registration Statement or the Prospectus contains a 
Misstatement, prepare a supplement or post-effective amendment to the 
Registration Statement or the related Prospectus or any document incorporated 
therein by reference or file any other required document so that, as 
thereafter delivered to the purchasers of the Registrable Securities, the 
Prospectus will not contain a Misstatement;

          (m)  use all commercially reasonable efforts to cause all 
Registrable Securities covered by the Registration Statement to be listed on 
any national securities exchange on which the Company's securities are listed 
or authorized for quotation on Nasdaq, if requested by the Investors (on 
behalf of themselves and all permitted assignees who are Holders of 
Registrable Securities) or the managing underwriter, if any; provided, 
however, that the payment of any required listing or other fee shall always 
be deemed to be "commercially reasonable" for purposes of this Section 5(m);

          (n)  provide a CUSIP number for all Registrable Securities not 
later than the effective date of the Registration Statement;

          (o)  enter into such agreements (including an underwriting 
agreement) and do anything else reasonably necessary or advisable in order to 
expedite or facilitate the disposition 


                                      11

<PAGE>

of such Registrable Securities, and in such connection, whether or not the 
registration is an Underwritten Registration:

          (1)  make such representations and warranties to the Holders of 
     such Registrable Securities and the underwriters, if any, in form, 
     substance and scope as are customarily made by issuers to holders and 
     underwriters, respectively, in similar Underwritten Offerings;

          (2)  obtain opinions of counsel to the Company and updates thereof

     Investor (on behalf of itself and all permitted assignees who are 
     Holders of Registrable Securities)) addressed to each selling Holder and 
     the underwriter, if any, covering the matters customarily covered in

     Underwritten Offerings and such other matters as may be reasonably 
     requested by such Investor or underwriters;

          (3)  obtain "cold comfort" letters and updates thereof from the 
     Company's independent certified public accountants addressed to the 
     selling Holders of Registrable Securities and the underwriters, if any, 
     such letters to be in customary form and covering matters of the type 
     customarily covered in "cold comfort" letters by holders and 
     underwriters, respectively, in connection with similar Underwritten 
     Offerings;

          (4)  if an underwriting agreement is entered into, cause the same to 
     include customary indemnification and contribution provisions and 
     procedures with respect to such underwriters; and

          (5)  deliver such documents and certificates as may be reasonably 
     requested by the Investor (on behalf of itself and all permitted 
     assignees who are Holders of Registrable Securities) and the managing 
     underwriter, if any, to evidence compliance with clause (1) above and 
     with any customary conditions contained in the underwriting agreement or 
     other agreement entered into by the Company.

The above shall be done at each closing under such underwriting or similar 
agreement or as and to the extent otherwise reasonably requested by the 
Investor (on behalf of itself and all permitted assignees who are Holders of 
Registrable Securities);

          (p)  make available for inspection by representatives of TC Group, 
L.L.C. or Carlyle Investment Management, L.L.C., as appropriate (on behalf of

such Registration Statement, and any attorney or accountant retained by the 
sellers or any such underwriter, all financial and other records and 
pertinent corporate documents and properties of the Company, and cause the 
Company's officers, directors and employees to supply all information 
reasonably requested by any such seller or underwriter in connection with the

confidential by such Persons 


                                      12

unless disclosure of such records, information or documents is required by 
court or administrative order; and

          (q)  otherwise use all commercially reasonable efforts to comply 
with all applicable rules and regulations of the SEC relating to such 
Registration, and make generally available to its security holders earnings 
statements satisfying the provisions of Section 11(a) of the Securities Act, 
no later than forty-five (45) days after the end of any 12-month period (or 
ninety (90) days, if such period is a fiscal year) commencing at the end of 
any fiscal quarter in which Registrable Securities are sold to underwriters 
in an Underwritten Offering, or, if not sold to underwriters in such an 
offering, beginning with the first month of the Company's first fiscal 
quarter commencing after the effective date of the Registration Statement, 
which statements shall cover said 12-month period.

6.   REGISTRATION EXPENSES

     (a)  DEMAND REGISTRATIONS.

          The Company shall bear all Registration Expenses incurred in 
connection with any Demand Registrations and of any Registrations which do 
not become or are not maintained effective in accordance with the 
requirements specified in Section 5(a) other than any Registration terminated 
prior to effectiveness at the request of, or primarily as a result of, the 
actions of Holders whose Registrable Securities are included in such 
registration. Notwithstanding the foregoing, the Underwriters' Commissions 
incurred in connection with a Demand Registration that becomes effective 
shall be shared by the Holders of the Registrable Securities whose 
Registrable Securities are included in such Registration and the Holders of 
the GE Registrable Securities whose GE Registrable Securities are included in 
such Registration, pro rata, in accordance with the aggregate amount of 
Registrable Securities and GE Registrable Securities sold by such Holders.

     (b)  PIGGYBACK REGISTRATIONS.

          The Company shall bear all Registration Expenses incurred in 
connection with any Piggyback Registrations, except that each Holder of the 
Registrable Securities whose Registrable Securities are included in such 
Registration shall pay its pro rata share of the Underwriters' Commissions 
incurred in such Registration, in accordance with the amount of Registrable 
Securities sold by all such Holders.

     (c)  COMPANY EXPENSES.

          The Company also will, in any event, pay its internal expenses 
(including, without limitation, all salaries and expenses of its officers and 
employees performing legal or accounting duties), the expense of any annual 
audit, the fees and expenses incurred in connection with any listing of the 
securities to be registered on a securities exchange, and the fees and 
expenses of any Person, including special experts, retained by the Company.

7.   INDEMNIFICATION

     (a)  INDEMNIFICATION BY COMPANY.

          The Company agrees to indemnify and hold harmless each Indemnified 
Holder from and against all Claims arising out of or based upon any 
Misstatement or alleged Misstatement, except insofar as such Misstatement or 
alleged Misstatement was based upon information furnished in writing to the 
Company by such Indemnified Holder expressly for use in the document 
containing such Misstatement or alleged Misstatement.  This indemnity shall 
not be exclusive and shall be in addition to any liability which the Company 
may otherwise have.

          The foregoing notwithstanding, the Company shall not be liable to 
the extent that any such Claim arises out of or is based upon a Misstatement 
or alleged Misstatement made in any preliminary prospectus if (i) such 
Indemnified Holder failed to send or deliver a copy of the Prospectus with or 
prior to the delivery of written confirmation of the sale of Registrable 
Securities giving rise to such Claim and (ii) the Prospectus would have 
corrected such untrue statement or omission.

          In addition, the Company shall not be liable to the extent that any 
such Claim arises out of or is based upon a Misstatement or alleged 
Misstatement in a Prospectus, (x) if such Misstatement or alleged 
Misstatement is corrected in an amendment or supplement to such Prospectus 
and (y) having previously been furnished by or on behalf of the Company with 
copies of the Prospectus as so amended or supplemented, such Indemnified 
Holder thereafter fails to deliver such Prospectus as so amended or 
supplemented prior to or concurrently with the sale to the person who 
purchased a Registrable Security from such Indemnified Holder and who is 
asserting such Claim.

          The Company shall also provide customary indemnifications to 
underwriters, selling brokers, dealer managers and similar securities 
industry professionals participating in a distribution covered by a 
Registration Statement, their officers and directors and each Person who 
controls such Persons (within the meaning of Section 15 of the Securities Act 
or Section 20 of the Exchange Act).

     (b)  INDEMNIFICATION PROCEDURES.

          If any action or proceeding (including any governmental 
investigation or inquiry) shall be brought or asserted against an Indemnified 
Holder in respect of which indemnity may be sought from the Company, such 
Indemnified Holder shall promptly notify the Company in writing, and the 
Company may assume the defense thereof, including the employment of counsel 
reasonably satisfactory to such Indemnified Holder and the payment of all 
expenses.

          Such Indemnified Holder shall have the right to employ separate 
counsel in any such action and to participate in the defense thereof, but the 
fees and expenses of such separate counsel shall be at the expense of such 
Indemnified Holder unless (i) the Company has agreed to pay such fees and 
expenses, (ii) the Company shall have failed to assume the defense of such 
action or proceeding or has failed to employ counsel reasonably satisfactory 
to such Indemnified 


                                      14

<PAGE>

Holder in any such action or proceeding, or (iii) the named parties to any 
such action or proceeding (including any impleaded parties) include both such 
Indemnified Holder and the Company, and such Indemnified Holder shall have 
been advised in writing by counsel that there may be one or more legal 
defenses available to such Indemnified Holder that are different from or 
additional to those available to the Company.

          If such Indemnified Holder notifies the Company in writing that it 
elects to employ separate counsel at the expense of the Company as permitted 
by the provisions of the preceding paragraph, the Company shall not have the 
right to assume the defense of such action or proceeding on behalf of such 
Indemnified Holder.  The foregoing notwithstanding, the Company shall not be 
liable for the reasonable fee and expenses of more than one separate firm of 
attorneys at any time for such Indemnified Holder and any other Indemnified 
Holders (which firm shall be designated in writing by such Indemnified 
Holders) in connection with any one such action or proceeding or separate but 
substantially similar or related actions or proceedings in the same 
jurisdiction arising out of the same general allegations or circumstances.

          The Company shall not be liable for any settlement of any such 
action or proceeding effected without its written consent, but if settled 
with its written consent, or if there be a final judgment for the plaintiff 
in any such action or proceeding, the Company agrees to indemnify and hold 
harmless such Indemnified Holders from and against any loss or liability by 
reason of such settlement or judgment.

     (c)  INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.

          Each Holder of Registrable Securities agrees to indemnity and hold 
harmless the Company, its directors and officers and each Person, if any, who 
controls the Company within the meaning of either Section 15 of the 
Securities Act or Section 20 of the Exchange Act to the same extent as the 
foregoing indemnity from the Company to such Holder, but only with respect to 
information relating to such Holder furnished in writing by such Holder 
expressly for use in any Registration Statement, Prospectus or preliminary 
prospectus.  In no event, however, shall the liability hereunder of any 
selling Holder of Registrable Securities be greater than the dollar amount of 
the proceeds received by such Holder upon the sale of the Registrable 
Securities giving rise to such indemnification obligation.

          In case any action or proceeding shall be brought against the 
Company or its directors or officers or any such controlling person, in 
respect of which indemnity may be sought against a Holder of Registrable 
Securities, such Holder shall have the rights and duties given the Company 
and the Company or its directors or officers or such controlling person shall 
have the rights and duties given to each Holder by Sections 7(a) and 7(b) 
above.

          The Company shall be entitled to receive indemnities from 
underwriters, selling brokers, dealer managers and similar securities 
industry professionals participating in the distribution, to the same extent 
as provided above with respect to information so furnished in writing by such 
Persons specifically for inclusion in any Prospectus or Registration 
Statement.


                                      15

<PAGE>

     (d)  CONTRIBUTION.

          If the indemnification provided for in this Section 7 is 
unavailable to an indemnified party under Section 7(a) or Section 7(c) above 
(other than by reason of exceptions provided in those Sections) in respect of 
any Claims referred to in such Sections, then each applicable indemnifying 
party, in lieu of indemnifying such indemnified party, shall contribute to 
the amount paid or payable by such indemnified party as a result of such 
Claims in such proportion as is appropriate to reflect the relative fault of 
the Company on the one hand and of the Holder on the other in connection with 
the statements or omissions which resulted in such Claims as well as any 
other relevant equitable considerations.  The amount paid or payable by a 
party as a result of the Claims referred to above shall be deemed to include, 
subject to the limitations set forth in Section 7(b), any legal or other fees 
or expenses reasonably incurred by such party in connection with 
investigating or defending any action or claim.

          The relative fault of the Company on the one hand and of the Holder 
on the other shall be determined by reference to, among other things, whether 
the Misstatement or alleged Misstatement relates to information supplied by 
the Company or by the Holder and the parties' relative intent, knowledge, 
access to information and opportunity to correct or prevent such Misstatement 
or alleged Misstatement.

          The Company and each Holder of Registrable Securities agree that it 
would not be just and equitable if contribution pursuant to this Section 7(d) 
were determined by pro rata allocation or by any other method of allocation 
which does not take account of the equitable considerations referred to above.

          Notwithstanding the provisions of this Section 7(d), an Indemnified 
Holder shall not be required to contribute any amount in excess of the amount 
by which (i) the total price at which the securities that were sold by such 
Indemnified Holder and distributed to the public were offered to the public 
exceeds (ii) the amount of any damages which such Indemnified Holder has 
otherwise been required to pay by reason of such Misstatement.

          No person guilty of fraudulent misrepresentation (within the 
meaning of Section 11(f) of the Securities Act) shall be entitled to 
contribution from any person who was not guilty of such fraudulent 
misrepresentation.

8.   EXCHANGE ACT REPORTING REQUIREMENTS

          From and after the date hereof, the Company shall (whether or not 
it shall then be required to do so) timely file such information, documents 
and reports as the Commission may require or prescribe under Section 13 or 
15(d) (whichever is applicable) of the Exchange Act.  In addition, the 
Company shall use all commercially reasonable efforts to file such other 
information, documents and reports, as shall hereafter be required by the 
Commission as a condition to the availability of Rule 144 under the 
Securities Act (or any successor provision) and the use of Form S-3.


                                      16

<PAGE>

          From and after the date hereof, the Company shall forthwith upon 
reasonable request furnish any Holder of Registrable Securities (i) a written 
statement by the Company that it has complied with such reporting 
requirements, (ii) a copy of the most recent annual or quarterly report of 
the Company, and (iii) such other reports and documents filed by the Company 
with the Commission as such Holder may reasonably request in availing itself 
of an exemption for the sale of Registrable Securities without registration 
under the Securities Act pursuant to Rule 144 thereunder.

          The purpose of the foregoing requirements are (a) to enable any 
such Holder to comply with the current public information requirements 
contained in paragraph (c) of Rule 144 under the Securities Act (or any 
successor provision) and (b) to qualify the Company for the use of 
Registration Statements on Form S-3.

9.   REQUIREMENTS FOR PARTICIPATION IN UNDERWRITTEN OFFERINGS

          No Person may participate in any Underwritten Offering pursuant to 
a Registration hereunder unless such Person (a) agrees to sell such Person's 
securities on the basis provided in any underwriting arrangements approved by 
the Persons entitled hereunder to approve such arrangements, and (b) 
completes and executes all questionnaires, powers of attorney, indemnities, 
underwriting agreements and other documents required under the terms of such 
underwriting arrangements

10.  SUSPENSION OF SALES

          Upon receipt of written notice from the Company that (i) a 
Registration Statement or Prospectus contains a Misstatement, or (ii) in the 
reasonable determination of the Company, there exists circumstances not yet 
disclosed to the public which would be required to be disclosed in such 
Registration Statement and the disclosure of which would be materially 
harmful to the Company, each Holder of Registrable Securities shall forthwith 
discontinue disposition of Registrable Securities until such Holder has 
received copies of the supplemented or amended Prospectus required by Section 
5(l) hereof, or until such Holder is advised in writing by the Company that 
the use of the Prospectus may be resumed, and, if so directed by the Company, 
such Holder shall deliver to the Company (at the Company's expense) all 
copies, other than permanent file copies then in such Holder's possession, of 
the Prospectus covering such Registrable Securities current at the time of 
receipt of such notice.  The Company shall use all commercially reasonable 
efforts to minimize the length of such suspension of sales, provided, that 
the Company may require the suspension of sales for a period of ninety (90) 
days in the event that the disclosure of any circumstances, in the reasonable 
determination of the Company would be harmful in any material respect to the 
Company.  In no event, however, shall the aggregate period of time that the 
Company postpones the filing or declaration of effectiveness of any 
Registration Statement pursuant to Section 5, or suspends sales of 
Registrable Securities pursuant to Section 10 under any Registration 
Statement, taken together with all such other periods with respect to such 
Registrations Statement exceed, in the aggregate, ninety (90) days.


                                      17

<PAGE>

11.  FUTURE REGISTRATION RIGHTS AGREEMENTS

          Except for an underwriting agreement between the Company and one or 
more professional underwriters of securities, the Company shall not agree to 
register any Equity Securities under the Securities Act unless such agreement 
specifically provides that:

          (a)  the Holder of such Equity Securities may not participate in any
Demand Registration without the consent of the Investors unless:

               (i)  the offering of the Registrable Securities is to be a Firm 
     Commitment Underwritten Offering and the managing underwriter concludes 
     that the public offering or sale of such Equity Securities would not 
     interfere with the successful marketing of all Registrable Securities 
     requested to be sold and

               (ii) the Holders of Registrable Securities shall have the right 
     to participate, to the extent they may request, in any Registration 
     Statement initiated under a Demand Registration right exercised by 
     Investors holding more than 50% of the Registrable Securities then 
     outstanding, except that if the managing underwriter of a public 
     offering made pursuant to such a Demand Registration limits the number 
     of shares of Common Stock to be sold, the participation of the Holders 
     of the Registrable Securities and the Holders of all other Common Stock 
     (other than the Equity Securities held by such Holder of Equity 
     Securities) shall be determined as set forth in Section 3 hereof.

          (b)  the Holder of such Equity Securities may not participate in 
any Piggyback Registration if the sale of Registrable Securities is to be 
underwritten unless, if the managing underwriter limits the total number of 
shares to be sold, the Holders of such Equity Securities and the Holders of 
Registrable Securities are entitled to participate in such underwritten 
distribution based on the order of priority set forth in Section 3 hereof, and

          (c)  all Equity Securities excluded from any Registration as a 
result of the foregoing limitations may not be publicly offered or sold for a 
period (not to exceed at least thirty (30) days prior to the effective date 
and sixty (60) days thereafter) that the managing underwriter reasonably 
determines is necessary in order to effect the underwritten public offering 
of Registrable Securities registered pursuant to this Agreement.

12.  TRANSFER OF REGISTRATION RIGHTS

          The rights of Holders of Registrable Securities hereunder may be 
transferred as permitted in the Purchase Agreement.  The Company shall be 
given written notice by the Holder at the time of any such transfer permitted 
by the Purchase Agreement stating the name and address of the transferee, 
including a writing by such transferee to the effect that such transferee 
agrees to by bound by the terms hereof and identifying the securities with 
respect to which the rights hereunder are being transferred.

13.  MISCELLANEOUS

     (a)  REMEDIES.

          Each Holder of Registrable Securities, in addition to being 
entitled to exercise all rights provided herein, in the Purchase Agreement 
and granted by law, including recovery of damages, shall be entitled to 
specific performance of its rights under this Agreement.  The Company agrees 
that monetary damages would not be adequate compensation for any loss 
incurred by reason of a breach by it of the provisions of this Agreement and 
hereby agrees to waive the defense in any action for specific performance 
that a remedy at law would be adequate.

     (b)  NO INCONSISTENT AGREEMENTS.

          The Company shall not, on or after the date of this Agreement, 
enter into any agreement with respect to its securities that is inconsistent 
with the rights granted to the Holders of Registrable Securities in this 
Agreement or otherwise conflicts with the provisions hereof.

          Other than as disclosed on Schedule A attached hereto, the Company 
has not previously entered into any agreement with respect to its securities 
granting any "piggy back" registration rights to any Person.  The Company 
represents and warrants to the Investors that, except as set forth in this 
Agreement and the GE Registration Rights Agreement, as of the date hereof, 
there are no outstanding "demand" registration rights with respect to the 
Company's securities.  The rights granted to the Holders of Registrable 
Securities hereunder do not in any way conflict with and are not inconsistent 
with the rights granted to the holders of the Company's securities under any 
such agreements.

     (c)  AMENDMENTS AND WAIVERS.

          The provisions of this Agreement, including the provisions of this 
sentence, may not be amended, modified or supplemented, and waivers or 
consents to departures from the provisions hereof may not be given unless the 
Company has obtained the written consent of General Electric Company, a New 
York corporation (but such consent of General Electric Company shall only be 
necessary if, at the time such consent is sought, GE owns GE Registrable 
Securities) and of Investors holding more than 50% of the Registrable 
Securities then outstanding (on behalf of themselves and all permitted 
assignees who are Holders of Registrable Securities).  The foregoing 
notwithstanding, a waiver or consent to departure from the provisions hereof 
that relates exclusively to the rights of Holders of shares of Registrable 
Securities whose shares are being sold pursuant to a Registration Statement 
and that does not directly or indirectly affect the rights of other Holders

notwithstanding, a security shall remain a Transfer Restricted Security until 
all stop transfer instructions or notations and restrictive legends with 
respect to such security have been lifted or removed.


                                      5

     "Underwriters' Commissions" shall mean discounts of and commissions to 
underwriters, selling brokers, dealer managers or similar securities 
professionals relating to the distribution of the Registrable Securities.

     "Underwritten Registration" or "Underwritten Offering" shall mean a 
registration in which securities of the Company are sold to an underwriter 
for distribution to the public.

     "Warrants" shall mean the warrants to purchase Common Stock issued 
pursuant to a Warrant Agreement dated of even date herewith by and between 
the Company and GE.

Section 2.     DEMAND REGISTRATIONS

     (a)  TIMING OF DEMAND REGISTRATIONS.

     GE (on behalf of itself and all permitted assignees who are Holders of 
Registrable Securities) may request at any time that the Company file a 
Registration Statement under the Securities Act on an appropriate form (which 
form shall be available for the sale of the Registrable Securities in 
accordance with the intended method or methods of distribution thereof and 
shall include all financial statements required by the SEC to be filed 
herewith) covering the shares of Registrable Securities that are the subject 
of such request.

     (b)  NUMBER OF DEMAND REGISTRATIONS; REQUIRED THRESHOLD.

     The Company shall be obligated to prepare, file and cause to become 
effective pursuant to this Section 2 no more than two (2) Registration 
Statements in the aggregate for GE (on behalf of itself and all permitted 
assignees who are Holders of Registrable Securities); provided, however, that 
a Registration Statement shall not be counted as one of the two (2) Demand 
Registrations hereunder unless it becomes effective and is maintained 
effective in accordance with the requirements specified in Section 5(a).  The 
Company shall not be obligated to prepare, file and cause to become effective 
pursuant to this Section 2 a Registration Statement unless the proposed 
aggregate public offering price of the Registrable Securities to be included 
in such Demand Registration is at least $5 million.

     (c)  DEFERRAL BY COMPANY.

     Notwithstanding anything in this Section 2 to the contrary, the Company 
shall not be obligated to prepare, file and cause to become effective 
pursuant to this Section 2 a Registration Statement if the Company furnishes 
GE a certificate signed by the President of the Company that in the good 
faith judgment of the Board of Directors it would be detrimental in any 
material respect to the Company and its shareholders for the Company to 
comply with the Demand Registration, and it is therefore essential to defer 
the filing of the Registration Statement relating thereto.  Any such deferral 
shall be for a period of not more than six (6) months after the Company's 
receipt of GE's written request for registration pursuant to this Section 2; 
PROVIDED, HOWEVER, that the Company may not exercise this right more than 
once with respect to a Demand Registration and that any requested 
registration deferred, and not ultimately effected, by the Company pursuant 
to the provisions of this Section 2(c) shall thereafter not be deemed to be a 


                                      6

<PAGE>

requested registration for purposes of the limitation to two (2) Demand 
Registrations pursuant to Section 2(a) above.

     (d)  PARTICIPATION.

     The Company shall promptly give written notice to all Holders of 
Registrable Securities and to the Carlyle Investors upon receipt of a request 
for a Demand Registration pursuant to Section 2(a) above.  The Carlyle 
Investors may, by written notice to the Company and GE, within thirty (30) 
business days of the Company's notice, elect to join in a request for a 
Demand Registration pursuant to Section 2(a) above, with respect to a number 
of shares of the Carlyle Investors' Registrable Securities that is less than 
or equal to the number of shares of Registrable Securities requested to be 
registered in such Demand Registration by GE.  The Carlyle Investors' 
Registrable Securities being offered by the Carlyle Investors in such Demand 
Registration shall be treated pari passu with the Registrable Securities 
being offered by GE for all purposes including "underwriter's cutbacks" under 
subsection (e) of this Section and any such request by the Carlyle Investors 
shall not be treated as either a request for "piggyback" rights under Section 
3 hereof or be treated as the exercise of a demand registration right by the 
Carlyle Investors under the Carlyle Investors' Registration Rights Agreement. 
 In addition, the Company shall include in such Demand Registration such 
shares of Registrable Securities for which it has received written requests 
to register such shares within thirty (30) days after such written notice has 
been given.

     (e)  UNDERWRITER'S CUTBACK.

     If the public offering of Registrable Securities and/or Carlyle 
Investors' Registrable Securities is to be underwritten and, in the good 
faith judgment of the managing underwriter, the inclusion of all the 
Registrable Securities and/or Carlyle Investors' Registrable Securities 
requested to be registered hereunder would interfere with the successful 
marketing of a smaller number of such shares of Registrable Securities and/or 
Carlyle Investors' Registrable Securities, the number of shares of 
Registrable Securities and/or Carlyle Investors' Registrable Securities to be 
included shall be reduced to such smaller number with the participation in 
such offering to be pro rata among the Holders of Registrable Securities 
and/or Carlyle Investors' Registrable Securities requesting such 
registration, based upon the number of shares of Registrable Securities 
and/or Carlyle Investors' Registrable Securities owned by such Holders.

     Any shares that are thereby excluded from the offering shall be withheld 
from the market by the Holders thereof for a period (not to exceed thirty 
(30) days prior to the effective date and one hundred twenty (120) days 
thereafter) that the managing underwriter reasonably determines is reasonably 
necessary in order to successfully market the securities to be offered in the 
Underwritten Offering.

     The Company and, subject to the requirements of Section 11 hereof, other 
Holders of securities of the Company may include such securities in such 
Registration if, but only if, the managing underwriter concludes that such 
inclusion will not interfere with the successful marketing of all the 
Registrable Securities requested to be included in such registration.


                                      7

<PAGE>

     (f)  MANAGING UNDERWRITER.

     The managing underwriter or underwriters of any Underwritten Offering 
covered by a Demand Registration shall be selected by GE (if GE owns a 
majority of the shares of Common Stock to be offered therein), subject to the 
approval of the Board of Directors (by a majority of the Directors not 
elected by the holders of the Preferred Stock and the Series B Preferred 
Stock), which approval shall not be unreasonably withheld.

3.   PIGGYBACK REGISTRATIONS

     (a)  PARTICIPATION.

     Each time the Company decides to file a Registration Statement under the 
Securities Act (other than registrations on Forms S-4 or S-8 or any successor 
form thereto, and other than a Demand Registration) covering the offer and 
sale by it or any of its security holders of any of its securities for money, 
the Company shall give written notice thereof to all Holders of Registrable 
Securities.  The Company shall include in such Registration Statement such 
shares of Registrable Securities for which it has received written requests 
to register such shares within twenty (20) days after such written notice has 
been given.  If the Registration Statement is to cover an Underwritten 
Offering, such Registrable Securities shall be included in the underwriting 
on the same terms and conditions as the securities otherwise being sold 
through the underwriters.

     (b)  UNDERWRITER'S CUTBACK.

     Subject to the requirements of Section 11 hereof, if in the good faith 
judgment of the managing underwriter of such offering the inclusion of all of 
the shares of Registrable Securities and any other Common Stock requested to 
be registered would interfere with the successful marketing of a smaller 
number of such shares, then the number of shares of Registrable Securities 
and other Common Stock to be included in the offering shall be reduced to 
such smaller number with the participation in such offering to be in the 
following order of priority:  (1) first, the shares of Common Stock which the 
Company proposes to sell for its own account, (2) second, the shares of 
Registrable Securities of all Holders of Registrable Securities requested to 
be included, PARI PASSU with all shares of Carlyle Investors' Registrable 
Securities requested by the Carlyle Investors to be included and all shares 
of any Person granted "piggyback" registration rights by the Company prior to 
the date hereof with respect to the Company's securities, as set forth in 
Schedule A attached hereto, requested by such Person to be included, and (3) 
third, any other shares of Common Stock requested to be included.  Any 
necessary allocation among the Holders of shares within each of the foregoing 
groups shall be pro rata among such Holders requesting such registration 
based upon the number of shares of Common Stock and Registrable Securities 
owned by such Holders.

     All shares so excluded from the Underwritten Offering shall be withheld 
from the market by the Holders thereof for a period (not to exceed thirty 
(30) days prior to the effective date and one hundred twenty (120) days 
thereafter) that the managing underwriter reasonably determines is reasonably 
necessary in order to successfully market the securities to be offered in the 
Underwritten Offering.


                                      8

<PAGE>

     (c)  COMPANY CONTROL.

     The Company may decline to file a Registration Statement after giving 
notice to Holders pursuant to Section 3(a) above, or withdraw a Registration 
Statement after filing and after such notice, but prior to the effectiveness 
thereof; provided that the Company shall promptly notify each Holder of 
Registrable Securities in writing of any such action and provided further 
that the Company shall bear all expenses incurred by each Holder or otherwise 
in connection with such withdrawn Registration Statement.

4.   HOLD-BACK AGREEMENTS

     (a)  BY HOLDERS OF REGISTRABLE SECURITIES

     Upon the written request of the managing underwriter of any Underwritten
Offering of the Company's securities, a Holder of Registrable Securities shall
not sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Registrable Securities (other than those included in
such registration) without the prior written consent of such managing
underwriter for a period (not to exceed thirty (30) days before the effective
date and one hundred twenty (120) days thereafter) that such managing
underwriter reasonably determines is necessary in order to effect the
Underwritten Offering; provided that each of the officers and directors of the
Company shall have entered into substantially similar holdback agreements with
such managing underwriter covering at least the same period.

     (b)  BY THE COMPANY AND OTHERS.

     The Company agrees:

               (1)  not to effect any public or private sale or distribution 
     of its Equity Securities during the 30-day period prior to, and during 
     the 60-day period after, the effective date of each Underwritten 
     Offering made pursuant to a Demand Registration or a Piggyback 
     Registration, if so requested in writing by the managing underwriter 
     (except as part of such Underwritten Offering, pursuant to registrations 
     on Forms S-4 or S-8 or any successor forms thereto or private issuances 
     of Equity Securities as consideration for any acquisition by the Company 
     or a subsidiary of assets or capital stock of any unaffiliated third 
     party), and

               (2)  not to issue any Equity Securities other than for sale in 
     a registered public offering unless each of the Persons to which such 
     securities are issued has entered a written agreement binding on its 
     transferees not to effect any public sale or distribution of such 
     securities (except for employee stock options issued to Persons other 
     than: directors or officers; or shareholders owning five percent (5%) or 
     more of the Company's Equity Securities) during such period, including 
     without limitation a sale pursuant to Rule 144 under the Securities Act 
     (except as part of such Underwritten Registration, if and to the extent 
     permitted hereunder).

5.   REGISTRATION PROCEDURES

     If and whenever the Company is required to register Registrable Securities
in a Demand Registration, the Company will use all commercially reasonable
efforts to effect such registration to permit the sale of such Registrable
Securities in accordance with the intended plan of distribution thereof.  With
respect to both Demand Registrations and Piggyback Registrations (except as
otherwise specifically provided), the Company will as expeditiously as
practicable:

     (a)  prepare and file with the SEC as soon as practicable a Registration
Statement with respect to such Registrable Securities and use all commercially
reasonable efforts to cause such Registration Statement to become effective and
remain continuously effective until the date that is the earlier to occur of (i)
the date six months from the date such Registration Statement was declared
effective, and (ii) the date the last of the Registrable Securities covered by
such Registration Statement have been sold, provided that before filing a
Registration Statement or Prospectus or any amendments or supplements thereto,
the Company shall furnish to Holders of Registrable Securities covered by such
Registration Statement and the underwriters, if any, draft copies of all such
documents proposed to be filed, which documents will be subject to the review of
GE and such underwriters, and the Company shall not file any Registration
Statement or amendment thereto or any Prospectus or any supplement thereto to
which GE or the underwriters, if any, shall reasonably object;

     (b)  prepare and file with the SEC such amendments and post-effective
amendments to the Registration Statement, and such supplements to the
Prospectus, as may be requested by any underwriter of Registrable Securities or
as may be required by the rules, regulations or instructions applicable to the
registration form used by the Company or by the Securities Act or rules and
regulations thereunder to keep the Registration Statement effective until all
Registrable Securities covered by such Registration Statement are sold in
accordance with the intended plan of distribution set forth in such Registration
Statement or supplement to the Prospectus;

     (c)  promptly notify the selling Holders of Registrable Securities and the
managing underwriter, if any, and (if requested by any such Person) confirm such
advice in writing,

               (1)  when the Prospectus or any supplement or post-effective
     amendment has been filed, and, with respect to the Registration Statement
     or any post-effective amendment, when the same has become effective,

               (2)  of any request by the SEC for amendments or supplements to
     the Registration Statement or the Prospectus or for additional information,

               (3)  of the issuance by the SEC of any stop order suspending the
     effectiveness of the Registration Statement or the initiation of any
     proceedings for that purpose,

               (4)  if at any time the representations and warranties of the
     Company contemplated by clause (1) of paragraph (o) below cease to be
     accurate in all material respects,


                                       10

<PAGE>

               (5)  of the receipt by the Company of any notification with
     respect to the suspension of the qualification of the Registrable
     Securities for sale in any jurisdiction or the initiation or threatening of
     any proceeding for such purpose, and

               (6)  of the existence of any fact which results in the
     Registration Statement, the Prospectus or any document incorporated therein
     by reference containing a Misstatement;

     (d)  make all commercially reasonable efforts to obtain the withdrawal of
any order suspending the effectiveness of the Registration Statement at the
earliest practicable time;

     (e)  unless the Company objects in writing on reasonable grounds, if
requested by the managing underwriter or GE (if GE holds more than 50% of the
Registrable Securities then outstanding) (on behalf of itself and all permitted
assignees who are Holders of Registrable Securities), as promptly as practicable
incorporate in a supplement or post-effective amendment such information as the
managing underwriter and GE agree should be included therein relating to the
sale of the Registrable Securities, including, without limitation, information
with respect to the number of shares of Registrable Securities being sold to
underwriters, the purchase price being paid therefor by such underwriters and
with respect to any other terms of the Underwritten Offering of the Registrable
Securities to be sold in such offering; and make all required filings of such
supplement or post-effective amendment as soon as notified of the matters to be
incorporated in such supplement or post-effective amendment;

     (f)  only with respect to Demand Registrations, promptly prior to the
filing of any document which is to be incorporated by reference into the
Registration Statement or the Prospectus (after initial filing of the
Registration Statement) provide copies of such document to counsel to GE (on
behalf of itself and all permitted assignees who are Holders of Registrable
Securities) and to the managing underwriter, if any, and make the Company's
representatives available for discussion of such document and make such changes
in such document prior to the filing thereof as counsel for GE or underwriters
may reasonably request;

     (g)  furnish to each selling Holder of Registrable Securities and the
managing underwriter, without charge, at least one signed copy of the
Registration Statement and any post-effective amendments thereto, including
financial statements and schedules, all documents incorporated therein by
reference and all exhibits (including those incorporated by reference);

     (h)  deliver to GE (on behalf of each selling Holder of Registrable
Securities) and the underwriters, if any, without charge, as many copies of each
Prospectus (and each preliminary prospectus) as such Persons may reasonably
request (the Company hereby consenting to the use of each such Prospectus (or
preliminary prospectus) by each of the selling Holders of Registrable Securities
and the underwriters, if any, in connection with the offering and sale of the
Registrable Securities covered by such Prospectus (or preliminary prospectus));

     (i)  prior to any public offering of Registrable Securities, use all
commercially reasonable efforts to register or qualify or cooperate with the
selling Holders of Registrable Securities, the underwriters, if any, and their
respective counsel in connection with the 


                                       11


<PAGE>

registration or qualification of such Registrable Securities for offer and 
sale under the securities or blue sky laws of such jurisdictions as GE or 
such underwriters may designate in writing and do anything else necessary or 
advisable to enable from a legal perspective the disposition in such 
jurisdictions of the Registrable Securities covered by the Registration 
Statement; provided that the Company shall not be required to qualify 
generally to do business in any jurisdiction where it is not then so 
qualified or to take any action which would subject it to general service of 
process in any such jurisdiction where it is not then so subject;

     (j)  cooperate with the selling Holders of Registrable Securities and the
managing underwriter, if any, to facilitate the timely preparation and delivery
of certificates not bearing any restrictive legends representing the Registrable
Securities to be sold and cause such Registrable Securities to be in such
denominations and registered in such names as the managing underwriter may
request at least three business days prior to any sale of Registrable Securities
to the underwriters;

     (k)  use all commercially reasonable efforts to cause the Registrable
Securities covered by the Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to enable the seller or sellers thereof or the underwriters, if any, to
consummate the disposition of such Registrable Securities;

     (l)  if the Registration Statement or the Prospectus contains a
Misstatement, prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of the Registrable Securities, the Prospectus will
not contain a Misstatement;

     (m)  use all commercially reasonable efforts to cause all Registrable
Securities covered by the Registration Statement to be listed on any national
securities exchange on which the Company's securities are listed or authorized
for quotation on Nasdaq, if requested by GE (on behalf of itself and all
permitted assignees who are Holders of Registrable Securities) or the managing
underwriter, if any; provided, however, that the payment of any required listing
or other fee shall always be deemed to be "commercially reasonable" for purposes
of this Section 5(m);

     (n)  provide a CUSIP number for all Registrable Securities not later than
the effective date of the Registration Statement;

     (o)  enter into such agreements (including an underwriting agreement) and
do anything else reasonably necessary or advisable in order to expedite or
facilitate the disposition of such Registrable Securities, and in such
connection, whether or not the registration is an Underwritten Registration:

               (1)  make such representations and warranties to the Holders of
     such Registrable Securities and the underwriters, if any, in form,
     substance and scope as are customarily made by issuers to holders and
     underwriters, respectively, in similar Underwritten Offerings;


                                       12


<PAGE>

               (2)  obtain opinions of counsel to the Company and updates
     thereof (which counsel and opinions (in form, scope and substance) shall be
     reasonably satisfactory to the managing underwriter, if any, and GE (on
     behalf of itself and all permitted assignees who are Holders of Registrable
     Securities)) addressed to each selling Holder and the underwriter, if any,
     covering the matters customarily covered in opinions delivered to holders
     and underwriters, respectively, in similar Underwritten Offerings and such
     other matters as may be reasonably requested by GE or such underwriters;

               (3)  obtain "cold comfort" letters and updates thereof from the
     Company's independent certified public accountants addressed to the selling
     Holders of Registrable Securities and the underwriters, if any, such
     letters to be in customary form and covering matters of the type
     customarily covered in "cold comfort" letters to holders and underwriters,
     respectively, in connection with similar Underwritten Offerings;

               (4)  if an underwriting agreement is entered into, cause the same
     to include customary indemnification and contribution provisions and
     procedures with respect to such underwriters; and

               (5)  deliver such documents and certificates as may be reasonably
     requested by GE (on behalf of itself and all permitted assignees who are
     Holders of Registrable Securities) and the managing underwriter, if any, to
     evidence compliance with clause (1) above and with any customary conditions
     contained in the underwriting agreement or other agreement entered into by
     the Company.

The above shall be done at each closing under such underwriting or similar
agreement or as and to the extent otherwise reasonably requested by GE (on
behalf of itself and all permitted assignees who are Holders of Registrable
Securities);

     (p)  make available for inspection by representatives of GE (on behalf of
itself and all permitted assignees who are Holders of Registrable Securities),
any underwriter participating in any disposition pursuant to such Registration
Statement, and any attorney or accountant retained by the sellers or any such
underwriter, all financial and other records and pertinent corporate documents
and properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such seller or
underwriter in connection with the Registration; provided that any records,
information or documents that are designated by the Company in writing as
confidential shall be kept confidential by such Persons unless disclosure of
such records, information or documents is required by court or administrative
order; and

     (q)  otherwise use all commercially reasonable efforts to comply with all
applicable rules and regulations of the SEC relating to such Registration, and
make generally available to its security holders earnings statements satisfying
the provisions of Section 11(a) of the Securities Act, no later than forty-five
(45) days after the end of any 12-month period (or ninety (90) days, if such
period is a fiscal year) commencing at the end of any fiscal quarter in which
Registrable Securities are sold to underwriters in an Underwritten Offering, or,
if not sold to underwriters in such an offering, beginning with the first month
of the Company's first fiscal quarter


                                       13


<PAGE>

commencing after the effective date of the Registration Statement, which 
statements shall cover said 12-month period.

6.   REGISTRATION EXPENSES

     (a)  DEMAND REGISTRATIONS.

     The Company shall bear all Registration Expenses incurred in connection
with any Demand Registrations and of any Registrations which do not become or
are not maintained effective in accordance with the requirements specified in
Section 5(a) other than any Registration terminated prior to effectiveness at
the request of, or primarily as a result of, the actions of Holders whose
Registrable Securities are included in such registration.  Notwithstanding the
foregoing, the Underwriters' Commissions incurred in connection with a Demand
Registration that becomes effective shall be shared by the Holders of the
Registrable Securities whose Registrable Securities are included in such
Registration and the Holders of the Carlyle Investors' Registrable Securities
whose Carlyle Investors' Registrable Securities are included in such
Registration, pro rata, in accordance with the aggregate amount of Registrable
Securities and Carlyle Investors' Registrable Securities sold by such Holders.

     (b)  PIGGYBACK REGISTRATIONS.

     The Company shall bear all Registration Expenses incurred in connection
with any Piggyback Registrations, except that each Holder of the Registrable
Securities whose Registrable Securities are included in such Registration shall
pay its pro rata share of the Underwriters' Commissions incurred in such
Registration, in accordance with the amount of Registrable Securities sold by
all such Holders.

     (c)  COMPANY EXPENSES.

     The Company also will, in any event, pay its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with any listing of the securities to
be registered on a securities exchange, and the fees and expenses of any Person,
including special experts, retained by the Company.

7.   INDEMNIFICATION

     (a)  INDEMNIFICATION BY COMPANY.

     The Company agrees to indemnify and hold harmless each Indemnified Holder
from and against all Claims arising out of or based upon any Misstatement or
alleged Misstatement, except insofar as such Misstatement or alleged
Misstatement was based upon information furnished in writing to the Company by
such Indemnified Holder expressly for use in the document containing such
Misstatement or alleged Misstatement.  This indemnity shall not be exclusive and
shall be in addition to any liability which the Company may otherwise have.


                                       14


<PAGE>

     The foregoing notwithstanding, the Company shall not be liable to the
extent that any such Claim arises out of or is based upon a Misstatement or
alleged Misstatement made in any preliminary prospectus if (i) such Indemnified
Holder failed to send or deliver a copy of the Prospectus with or prior to the
delivery of written confirmation of the sale of Registrable Securities giving
rise to such Claim and (ii) the Prospectus would have corrected such untrue
statement or omission.

     In addition, the Company shall not be liable to the extent that any such
Claim arises out of or is based upon a Misstatement or alleged Misstatement in a
Prospectus, (x) if such Misstatement or alleged Misstatement is corrected in an
amendment or supplement to such Prospectus and (y) having previously been
furnished by or on behalf of the Company with copies of the Prospectus as so
amended or supplemented, such Indemnified Holder thereafter fails to deliver
such Prospectus as so amended or supplemented prior to or concurrently with the
sale to the person who purchased a Registrable Security from such Indemnified
Holder and who is asserting such Claim.

     The Company shall also provide customary indemnifications to underwriters,
selling brokers, dealer managers and similar securities industry professionals
participating in a distribution covered by a Registration Statement, their
officers and directors and each Person who controls such Persons (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act).

     (b)  INDEMNIFICATION PROCEDURES.

     If any action or proceeding (including any governmental investigation or
inquiry) shall be brought or asserted against an Indemnified Holder in respect
of which indemnity may be sought from the Company, such Indemnified Holder shall
promptly notify the Company in writing, and the Company may assume the defense
thereof, including the employment of counsel reasonably satisfactory to such
Indemnified Holder and the payment of all expenses.

     Such Indemnified Holder shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such separate counsel shall be at the expense of such Indemnified
Holder unless (i) the Company has agreed to pay such fees and expenses, (ii) the
Company shall have failed to assume the defense of such action or proceeding or
has failed to employ counsel reasonably satisfactory to such Indemnified Holder
in any such action or proceeding, or (iii) the named parties to any such action
or proceeding (including any impleaded parties) include both such Indemnified
Holder and the Company, and such Indemnified Holder shall have been advised in
writing by counsel that there may be one or more legal defenses available to
such Indemnified Holder that are different from or additional to those available
to the Company.

     If such Indemnified Holder notifies the Company in writing that it elects
to employ separate counsel at the expense of the Company as permitted by the
provisions of the preceding paragraph, the Company shall not have the right to
assume the defense of such action or proceeding on behalf of such Indemnified
Holder.  The foregoing notwithstanding, the Company shall not be liable for the
reasonable fee and expenses of more than one separate firm of attorneys


                                       15

at any time for such Indemnified Holder and any other Indemnified Holders 
(which firm shall be designated in writing by such Indemnified Holders) in 
connection with any one such action or proceeding or separate but 
substantially similar or related actions or proceedings in the same 
jurisdiction arising out of the same general allegations or circumstances.

     The Company shall not be liable for any settlement of any such action or
proceeding effected without its written consent, but if settled with its written
consent, or if there be a final judgment for the plaintiff in any such action or
proceeding, the Company agrees to indemnify and hold harmless such Indemnified
Holders from and against any loss or liability by reason of such settlement or
judgment.

     (c)  INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.

     Each Holder of Registrable Securities agrees to indemnity and hold harmless
the Company, its directors and officers and each Person, if any, who controls
the Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to such Holder, but only with respect to information relating
to such Holder furnished in writing by such Holder expressly for use in any
Registration Statement, Prospectus or preliminary prospectus.  In no event,
however, shall the liability hereunder of any selling Holder of Registrable
Securities be greater than the dollar amount of the proceeds received by such
Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

     In case any action or proceeding shall be brought against the Company or
its directors or officers or any such controlling person, in respect of which
indemnity may be sought against a Holder of Registrable Securities, such Holder
shall have the rights and duties given the Company and the Company or its
directors or officers or such controlling person shall have the rights and
duties given to each Holder by Sections 7(a) and 7(b) above.

     The Company shall be entitled to receive indemnities from underwriters,
selling brokers, dealer managers and similar securities industry professionals
participating in the distribution, to the same extent as provided above with
respect to information so furnished in writing by such Persons specifically for
inclusion in any Prospectus or Registration Statement.

     (d)  CONTRIBUTION.

     If the indemnification provided for in this Section 7 is unavailable to an
indemnified party under Section 7(a) or Section 7(c) above (other than by reason
of exceptions provided in those Sections) in respect of any Claims referred to
in such Sections, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Claims in such proportion
as is appropriate to reflect the relative fault of the Company on the one hand
and of the Holder on the other in connection with the statements or omissions
which resulted in such Claims as well as any other relevant equitable
considerations.  The amount paid or payable by a party as a result of the Claims
referred to above shall be deemed to include, subject to the limitations set
forth in 


                                       16


<PAGE>


Section 7(b), any legal or other fees or expenses reasonably incurred
by such party in connection with investigating or defending any action or claim.

     The relative fault of the Company on the one hand and of the Holder on the
other shall be determined by reference to, among other things, whether the
Misstatement or alleged Misstatement relates to information supplied by the
Company or by the Holder and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such Misstatement or alleged
Misstatement.

     The Company and each Holder of Registrable Securities agree that it would
not be just and equitable if contribution pursuant to this Section 7(d) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above.

     Notwithstanding the provisions of this Section 7(d), an Indemnified Holder
shall not be required to contribute any amount in excess of the amount by which
(i) the total price at which the securities that were sold by such Indemnified
Holder and distributed to the public were offered to the public exceeds (ii) the
amount of any damages which such Indemnified Holder has otherwise been required
to pay by reason of such Misstatement.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

8.   EXCHANGE ACT REPORTING REQUIREMENTS

     From and after the date hereof, the Company shall (whether or not it shall
then be required to do so) timely file such information, documents and reports
as the Commission may require or prescribe under Section 13 or 15(d) (whichever
is applicable) of the Exchange Act.  In addition, the Company shall use all
commercially reasonable efforts to file such other information, documents and
reports, as shall hereafter be required by the Commission as a condition to the
availability of Rule 144 under the Securities Act (or any successor provision)
and the use of Form S-3.

     From and after the date hereof, the Company shall forthwith upon reasonable
request furnish any Holder of Registrable Securities (i) a written statement by
the Company that it has complied with such reporting requirements, (ii) a copy
of the most recent annual or quarterly report of the Company, and (iii) such
other reports and documents filed by the Company with the Commission as such
Holder may reasonably request in availing itself of an exemption for the sale of
Registrable Securities without registration under the Securities Act pursuant to
Rule 144 thereunder.

     The purpose of the foregoing requirements are (a) to enable any such 
Holder to comply with the current public information requirements contained 
in paragraph (c) of Rule 144 under the Securities Act (or any successor 
provision) and (b) to qualify the Company for the use of Registration 
Statements on Form S-3.

                                       17

9.   REQUIREMENTS FOR PARTICIPATION IN UNDERWRITTEN OFFERINGS

     No Person may participate in any Underwritten Offering pursuant to a
Registration hereunder unless such Person (a) agrees to sell such Person's
securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements, and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements

10.  SUSPENSION OF SALES

     Upon receipt of written notice from the Company that (i) a Registration
Statement or Prospectus contains a Misstatement, or (ii) in the reasonable
determination of the Company, there exist circumstances not yet disclosed to the
public which would be required to be disclosed in such Registration Statement
and the disclosure of which would be materially harmful to the Company, each
Holder of Registrable Securities shall forthwith discontinue disposition of
Registrable Securities until such Holder has received copies of the supplemented
or amended Prospectus required by Section 5(l) hereof, or until such Holder is
advised in writing by the Company that the use of the Prospectus may be resumed,
and, if so directed by the Company, such Holder shall deliver to the Company (at
the Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Registrable Securities
current at the time of receipt of such notice.  The Company shall use all
commercially reasonable efforts to minimize the length of such suspension of
sales, provided, that the Company may require the suspension of sales for a
period of ninety (90) days in the event that the disclosure of any
circumstances, in the reasonable determination of the Company, would be harmful
in any material respect to the Company.  In no event, however, shall the
aggregate period of time that the Company postpones the filing or declaration of
effectiveness of any Registration Statement pursuant to Section 5, or suspends
sales of Registrable Securities pursuant to Section 10 under any Registration
Statement, taken together with all such other periods with respect to such
Registrations Statement exceed, in the aggregate, ninety (90) days.

11.  FUTURE REGISTRATION RIGHTS AGREEMENTS

     Except for an underwriting agreement between the Company and one or more
professional underwriters of securities, the Company shall not agree to register
any Equity Securities under the Securities Act unless such agreement
specifically provides that:

     (a)  the Holder of such Equity Securities may not participate in any Demand
Registration without the consent of GE unless:

               (i)  the offering of the Registrable Securities is to be a Firm
     Commitment Underwritten Offering and the managing underwriter concludes
     that the public offering or sale of such Equity Securities would not
     interfere with the successful marketing of all Registrable Securities
     requested to be sold and


                                       18


<PAGE>

               (ii) the Holders of Registrable Securities shall have the right
     to participate, to the extent they may request, in any Registration
     Statement initiated under a Demand Registration right exercised GE (if GE
     holds more than 50% of the Registrable Securities then outstanding), except
     that if the managing underwriter of a public offering made pursuant to such
     a Demand Registration limits the number of shares of Common Stock to be
     sold, the participation of the Holders of the Registrable Securities and
     the Holders of all other Common Stock (other than the Equity Securities
     held by such Holder of Equity Securities) shall be determined as set forth
     in Section 3 hereof.

     (b)  the Holder of such Equity Securities may not participate in any
Piggyback Registration if the sale of Registrable Securities is to be
underwritten unless, if the managing underwriter limits the total number of
shares to be sold, the Holders of such Equity Securities and the Holders of
Registrable Securities are entitled to participate in such underwritten
distribution based on the order of priority set forth in Section 3 hereof, and

     (c)  all Equity Securities excluded from any Registration as a result of
the foregoing limitations may not be publicly offered or sold for a period (not
to exceed at least thirty (30) days prior to the effective date and sixty (60)
days thereafter) that the managing underwriter reasonably determines is
necessary in order to effect the underwritten public offering of Registrable
Securities registered pursuant to this Agreement.

12.  TRANSFER OF REGISTRATION RIGHTS

     The rights of Holders of Registrable Securities hereunder may be
transferred as permitted in the Purchase Agreement.  The Company shall be given
written notice by the Holder at the time of any such transfer permitted by the
Purchase Agreement stating the name and address of the transferee, including a
writing by such transferee to the effect that such transferee agrees to be bound
by the terms hereof and identifying the securities with respect to which the
rights hereunder are being transferred.

13.  MISCELLANEOUS

     (a)  REMEDIES.

     Each Holder of Registrable Securities, in addition to being entitled to
exercise all rights provided herein, in the Purchase Agreement and granted by
law, including recovery of damages, shall be entitled to specific performance of
its rights under this Agreement.  The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it
of the provisions of this Agreement and hereby agrees to waive the defense in
any action for specific performance that a remedy at law would be adequate.

     (b)  NO INCONSISTENT AGREEMENTS.

     The Company shall not, on or after the date of this Agreement, enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof.


                                       19


<PAGE>

     Other than as disclosed on Schedule A attached hereto, the Company has not
previously entered into any agreement with respect to its securities granting
any "piggy back" registration rights to any Person.  The Company represents and
warrants to GE that, except as set forth in this Agreement and the Carlyle
Investors' Registration Rights Agreement, as of the date hereof, there are no
outstanding "demand" registration rights with respect to the Company's
securities.  The rights granted to the Holders of Registrable Securities
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's securities under any such
agreements.

     (c)  AMENDMENTS AND WAIVERS.

     The provisions of this Agreement, including the provisions of this
sentence, may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given unless the Company has
obtained the written consent of the Carlyle Investors (but such consent of the
Carlyle Investors shall only be necessary if, at the time such consent is
sought, the Carlyle Investors own the Carlyle Investors' Registrable Securities)
and of GE (if GE holds more than 50% of the Registrable Securities then
outstanding) (on behalf of itself and all permitted assignees who are Holders of
Registrable Securities).  The foregoing notwithstanding, a waiver or consent to
departure from the provisions hereof that relates exclusively to the rights of
Holders of shares of Registrable Securities whose shares are being sold pursuant
to a Registration Statement and that does not directly or indirectly affect the
rights of other Holders of shares of Registrable Securities may be given by the
Holders of a majority of the shares of Registrable Securities being sold.

     (d)  NOTICES.

     All notices and other communications provided for or permitted hereunder
shall be made in writing by hand-delivery, registered first-class mail, telex,

                                WARRANT AGREEMENT
               
         THIS WARRANT AGREEMENT (the "Agreement") is made as of October 14,

"Warrant Holder").

                                W I T N E S S E T H :
                                - - - - - - - - - -

         WHEREAS, the Company has entered into (i) that certain Securities 
Purchase Agreement with the Warrant Holders dated as of October 14, 1997 (the 
"Purchase Agreement"), pursuant to which the Company agrees, among other 
things, to issue to the Warrant Holders warrants (the "Warrants") to purchase 
up to an aggregate of two hundred fifty thousand (250,000) shares of common 
stock, $.001 par value per share, of the Company (the "Common Stock," and the 
Common Stock issuable upon exercise of the Warrants being herein referred to 
as the "Warrant Shares"), and (ii) that certain Securities Purchase Agreement 
with General Electric Company ("GE") dated as of October 14, 1997, pursuant 
to which the Company agrees, among other things, to issue to GE warrants (the 
"GE Warrant") to purchase up to an aggregate of two hundred fifty hundred 
thousand (250,000) shares of Common Stock of the Company. Each Warrant shall 
be a warrant to purchase one (1) Warrant Share, unless and until adjusted 
pursuant to Section 10 hereof.  Certain terms used herein and not elsewhere 
defined are defined in the Purchase Agreement.
         
         NOW, THEREFORE, in consideration of the premises and the mutual 
agreements herein set forth, and for other good and lawful consideration, the 
receipt, sufficiency and adequacy of which are hereby acknowledged, the 
parties hereto agree as follows:
         
         SECTION 1.     WARRANT CERTIFICATE. 

         The certificates evidencing the Warrants (the "Warrant 
Certificates") to be delivered pursuant to this Agreement shall be in 
registered form only and shall be substantially in the form set forth in 
Exhibit A attached hereto.
         
         SECTION 2.     EXECUTION OF WARRANT CERTIFICATE. 

         (a)  The Warrant Certificates shall be signed on behalf of the 
Company by its Chairman of the Board of Directors (the "Board") or its 
President or a Vice President, and by its Secretary or an Assistant Secretary 
under its corporate seal.  Each such signature upon the Warrant Certificates 
may be in the form of a facsimile signature of the present or any future 
Chairman of the Board, President, Vice President, Secretary or Assistant 
Secretary, as the case may be, and may be imprinted or otherwise


                                      1

<PAGE>

reproduced on the Warrant Certificates.  The seal of the Company may be in 
the form of a facsimile thereof and may be impressed, affixed, imprinted or 
otherwise reproduced on the Warrant Certificates.

         (b)  In case any officer of the Company who shall have signed any 
Warrant Certificate shall cease to be such officer before the Warrant 
Certificate so signed shall have been disposed of by the Company, such 
Warrant Certificate nevertheless may be delivered or disposed of as though 
such person had not ceased to be such officer of the Company; and any Warrant 
Certificate may be signed on behalf of the Company by any person who, at the 
actual date of the execution of such Warrant Certificate, shall be a proper 
officer of the Company to sign such Warrant Certificate, although at the date 
of the execution of this Agreement any such person was not such officer.
         
         SECTION 3.     REGISTRATION.

         The Company shall register the Warrant Certificates in a Warrant 
register to be maintained by the Company (the "Warrant Register") when 
Warrants are issued. The Company may deem and treat the registered holders of 
the Warrant Certificates as the absolute owners thereof (notwithstanding any 
notation of ownership or other writing thereon made by anyone) for all 
purposes and shall not be affected by any notice to the contrary.

         SECTION 4.     REGISTRATION OF TRANSFERS AND EXCHANGES.  

         (a)  The Company shall from time to time register the transfer of 
any outstanding Warrant Certificate in the Warrant Register upon surrender 
thereof accompanied by a written instrument or instruments of transfer in 
form satisfactory to the Company, duly executed by the registered holder or 
holders thereof or by the duly appointed legal representative thereof or by a 
duly authorized attorney. Upon any such registration of transfer, a new 
Warrant Certificate shall be issued to the transferee and the surrendered 
Warrant Certificate shall be canceled and disposed of by the Company.

         (b)  The Warrant Holders agree that prior to any proposed transfer 
of the Warrants or of the Warrant Shares, which transfer shall not be to any 
Person engaged in the Business, if such transfer is not made pursuant to an 
effective Registration Statement under the Securities Act of 1933, as amended 
(the "Securities Act"), the Warrant Holder(s) will, if requested by the 
Company, deliver to the Company:
         
              (1)  an investment representation letter reasonably 
          satisfactory to the Company signed by the proposed transferee;

              (2)  an agreement by such transferee to the impression of the 
          restrictive investment legend set forth below in Section 4(c) on 
          the Warrants or the Warrant Shares;

              (3)  an agreement by such transferee that the Company may place 
          a notation in the stock books of the Company or a "stop transfer 
          order" with any transfer agent or registrar with respect to the 
          Warrant Shares;

              (4)  an agreement by such transferee to be bound by the 
          provisions of this Section 4 relating to the transfer of such 
          Warrants or Warrant Shares; and

              (5)  except in the case of a transfer pursuant to Rule 144 
          promulgated pursuant to the Securities Act, or any successor rule, 
          prior to consummating any private sale or transfer of such Warrants 
          or Warrant Shares, the written opinion of reputable legal counsel 
          in form reasonably

          acceptable to the Company that such sale or transfer is being made 
          in compliance with applicable federal securities laws.

              (c)  The Warrant Holders agree that each certificate 
          representing Warrants or Warrant Shares will bear the following 
          legend until such Warrants or Warrant Shares have been sold 
          pursuant to an effective registration statement under the 
          Securities Act:

                   "THE SECURITIES EVIDENCED OR CONSTITUTED HEREBY HAVE 
                    BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN 
                    REGISTERED UNDER THE SECURITIES ACT OF 1933, AS 
                    AMENDED. SUCH SECURITIES MAY NOT BE SOLD, 
                    TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE 
                    DISPOSED OF IN THE ABSENCE OF REGISTRATION UNDER 
                    SAID ACT AND THE RULES AND REGULATIONS THEREUNDER 
                    AND OF ALL APPLICABLE STATE SECURITIES OR "BLUE SKY" 
                    LAWS OR AN EXEMPTION THEREFROM UNDER SAID ACT AND 
                    ALL APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS.  
                    IN THE CASE OF A SALE OF THE SECURITIES EVIDENCED OR 
                    CONSTITUTED HEREBY, OTHER THAN A SALE PURSUANT TO A 
                    VALID REGISTRATION STATEMENT UNDER SAID ACT OR A 
                    SALE PURSUANT TO RULE 144 PROMULGATED UNDER SAID 
                    ACT, THE HOLDER OF THE SECURITIES EVIDENCED OR 
                    CONSTITUTED HEREBY SHALL PROVIDE TO THE CORPORATION 
                    THE WRITTEN OPINION OF REPUTABLE LEGAL COUNSEL IN 
                    FORM REASONABLY ACCEPTABLE TO THE CORPORATION THAT 
                    SUCH SALE OR TRANSFER IS BEING MADE IN COMPLIANCE 
                    WITH APPLICABLE FEDERAL SECURITIES LAWS."

         (d)  A Warrant Certificate may be exchanged at the option of the 
holder(s) thereof, when surrendered to the Company at its office for another 
Warrant Certificate or other Warrant Certificates of like tenor and 
representing in the aggregate a like number of Warrants. A Warrant 
Certificate surrendered for exchange shall be canceled and disposed of by the 
Company

         SECTION 5.     WARRANTS; EXERCISE OF WARRANTS.  

         (a)  Subject to the terms of this Agreement, the Warrant Holders 
shall have the right, which may be exercised during the period commencing on 
the Effective Date until 5:00 p.m., Washington, D.C. time, on the fifth 
anniversary of the Effective Date (the "Exercise Period"), to receive from 
the Company the number of fully paid and non-assessable Warrant Shares that 
the Warrant Holder may at the time be entitled to receive on exercise of the 
number of Warrants that the Warrant Holder elects to exercise and payment of 
the Exercise Price (as defined below) then in effect for such Warrant Shares. 
 In the alternative, the Warrant Holder may exercise its right, during the 
Exercise Period, to receive Warrant Shares on a net basis, such that, without 
payment of any funds kind, the Warrant Holder receives that number of Warrant 
Shares equal to the number of Warrants being exercised times the quotient of 
(i) the "fair market value" of a Warrant Share (as defined below) minus the 
Exercise Price, divided by (ii) the fair market value of a Warrant Share.  
For purposes of the foregoing sentence, "fair market value" of a Warrant 
Share shall mean the average of the closing prices of the Common Stock's 
sales on all domestic 


                                      3
<PAGE>

securities exchanges on which such Common Stock may at the time be listed, 
or, if there have been no sales on any such exchange on any day, the average 
of the highest bid and lowest asked prices on all such exchanges at the end 
of such day, or, if on any day such Common Stock is not so listed, the 
average of the representative bid and asked prices quoted on Nasdaq as of 
4:00 P.M., New York time, on such day, or, if on any day such Common Stock is 
not quoted on Nasdaq, the average of the highest bid and lowest asked prices 
on such day in the domestic over-the-counter market as reported by the 
National Quotation Bureau, Incorporated, or any similar successor 
organization, in each such case averaged over a period of twenty-one (21) 
business days consisting of the day as of which the "fair market value" of 
the Warrant Shares is being determined and the twenty (20) consecutive 
business days prior to such day; provided that if such Common Stock is listed 
on any domestic securities exchange the term "business days" as used in this 
sentence means business days on which such exchange is open for trading.  If 
at any time such Common Stock is not listed on any domestic securities 
exchange or quoted on Nasdaq or the domestic over-the-counter market, the 
"fair market value" of the Warrant Shares shall be the fair value thereof 
determined by the Company and approved by the Warrant Holder; provided that 
if such parties are unable to reach agreement within a reasonable period of 
time, such fair market value shall be determined by an appraiser reasonably 
selected by the Company and reasonably approved by the Warrant Holder.  The 
determination of such appraiser shall be final and binding on the Company and 
the Warrant Holder, and the fees and expenses of such appraiser shall be paid 
by the Company, unless the fair market value determined by such appraiser is 
less than five percent (5%) above the value proposed in writing by the 
Company and rejected by the Warrant Holder prior to the selection of such 
appraiser, in which event the fees and expenses of such appraiser shall be 
for the Warrant Holder's account.  Each Warrant not exercised prior to 5:00 
p.m., Washington, D.C. time, on the fifth anniversary of the Effective Date 
shall become void and all rights thereunder and all rights in respect thereof 
under this agreement shall cease as of such time.  No adjustments as to 
dividends will be made upon exercise of the Warrants.

         (b)  A Warrant may be exercised upon surrender to the Company at its 
office designated for such purpose (the address of which is set forth in 
Section 14 hereof) of the certificate or certificates evidencing the Warrants 
to be exercised with the form of election to purchase on the reverse thereof 
duly filled in and signed, and upon (i) payment to the Company of the 
exercise price of ten dollars ($10.00) per Warrant Share, as adjusted as 
herein provided (as so adjusted, the "Exercise Price"), for the number of 
Warrant Shares in respect of which such Warrants are then exercised, or (ii) 
the Warrant Holder's exercise of its right to receive Warrant Shares on a net 
basis, as more fully described in Section 5(a).  Payment of the aggregate 
Exercise Price shall be made (i) in cash or by certified or official bank 
check payable to the order of the Company or (ii) in the manner provided in 
subsection (a) of this Section 5.
         
         (c)  Subject to the provisions of Section 6 hereof, upon such 
surrender of Warrants and payment of the Exercise Price, the Company shall 
issue and cause to be delivered with all reasonable dispatch to or upon the 
written order of the Warrant Holder and in such name or names as the Warrant 
Holder may designate, a certificate or certificates for the number of full 
Warrant Shares issuable upon the exercise of such Warrants together with cash 
as provided in Section 11; PROVIDED, HOWEVER, that if any consolidation, 
merger, or sale or other transfer of all or substantially all of the assets 
of the Company is proposed to be effected by the Company, or a tender offer 
or an exchange offer for shares of Common Stock of the Company shall be made, 
upon such surrender of Warrants and payment of the Exercise Price as 
aforesaid, the Company shall, as soon as practicable, but in any event not 
later than five business days thereafter, issue and cause to be delivered the 
full number of Warrant Shares issuable upon the exercise of such Warrants in 
the manner described in this sentence together with cash as provided in 
Section 11.  Such certificate or certificates shall be deemed to have been 
issued and any person so designated to be named therein shall be deemed to 
have become a holder of record of such Warrant Shares as of the date of the 
surrender of such Warrants and payment of the Exercise Price.


                                      4         

<PAGE>

         (d)  The Warrants shall be exercisable, at the election of the 
holder thereof, either in full or from time to time in part and, in the event 
that a Warrant Certificate evidencing Warrants is exercised in respect of 
fewer than all of the Warrant Shares issuable on such exercise at any time 
prior to the date of expiration of the Warrants, a new Warrant Certificate 
evidencing the remaining Warrant or Warrants will be issued and delivered by 
the Company and at its expense pursuant to the provisions of this Section and 
of Section 2 hereof.
         
         (e)  All Warrant Certificates surrendered upon exercise of Warrants 
shall be canceled and disposed of by the Company. The Company shall keep 
copies of this Agreement and any notices given or received hereunder 
available for inspection by the Warrant Holder during normal business hours 
at its office.

          SECTION 6.     PAYMENT OF TAXES. 

          The Company will pay all documentary stamp taxes or other similar 
taxes attributable to the initial issuance of Warrant Shares upon the 
exercise of Warrants; PROVIDED, HOWEVER, that the Company shall not be 
required to pay any tax or taxes which may be payable in respect of any 
transfer involved in the issue of any Warrant Certificate or any certificates 
for Warrant Shares in a name other than that of the registered holder of a 
Warrant Certificate surrendered upon the exercise of a Warrant, and the 
Company shall not be required to issue or deliver such Warrant Certificates 
unless or until the person or persons requesting the issuance thereof shall 
have paid to the Company the amount of such tax or shall have established to 
the satisfaction of the Company that such tax has been paid.

         SECTION 7.     MUTILATED OR MISSING WARRANT CERTIFICATES.  
         
         In case any of the Warrant Certificates shall be mutilated, lost, 
stolen or destroyed, the Company may issue, in exchange and substitution for, 
and upon cancellation of, the mutilated Warrant Certificate, or in lieu of 
and substitution for the Warrant Certificate lost, stolen or destroyed, a new 
Warrant Certificate of like tenor and representing an equivalent number of 
Warrants, but only upon receipt of evidence reasonably satisfactory to the 
Company of such loss, theft or destruction of such Warrant Certificate and 
indemnity, if requested, also reasonably satisfactory to it. Applicants for 
such substitute Warrant Certificates shall also comply with such other 
reasonable regulations and pay such other reasonable charges as the Company 
may prescribe.
         
         SECTION 8.     RESERVATION OF WARRANT SHARES. 
   
         (a)  The Company will at all times reserve and keep available, free 
from preemptive rights, out of the aggregate of its authorized but unissued 
Common Stock or its authorized and issued Common Stock held in its treasury, 
for the purpose of enabling it to satisfy any obligation to issue Warrant 
Shares upon exercise of Warrants, the maximum number of shares of Common 
Stock which may then be deliverable upon the exercise of all outstanding 
Warrants.
 
         (b)  The Company or, if appointed, the transfer agent for the Common 
Stock (the "Transfer Agent") and every subsequent Transfer Agent for any 
shares of the Company's capital stock issuable upon the exercise of any of 
the rights of purchase aforesaid will be irrevocably authorized and directed 
at all times to reserve such number of authorized shares as shall be required 
for such purpose. The Company will keep a copy of this Agreement on file with 
the Transfer Agent and with every subsequent transfer agent for any shares of 
the Company's capital stock issuable upon the exercise of the rights of 
purchase 


                                      5

<PAGE>

represented by the Warrants.  The Company will furnish such Transfer 
Agent a copy of all notices of adjustments and certificates related thereto 
transmitted to each holder pursuant to Section 13 hereof.
         
         (c)  Before taking any action which would cause an adjustment 
pursuant to Section 10 hereof to reduce the Exercise Price below the then par 
value (if any) of the Warrant Shares, the Company will take any corporate 
action which may, in the opinion of its counsel (which may be counsel 
employed by the Company), be necessary in order that the Company may validly 
and legally issue fully paid and nonassessable Warrant Shares at the Exercise 
Price as so adjusted.
         
        (d)  The Company covenants that all Warrant Shares which may be 
issued upon exercise of Warrants will, upon issue, be fully paid, 
nonassessable, free of preemptive rights and free from all taxes, liens, 
charges and security interests with respect to the issue thereof

         SECTION 9.     STOCK EXCHANGE LISTINGS. 

         The Company will from time to time take all commercially reasonable 
action, at its expense, which may be necessary so that the Warrant Shares, 
immediately upon their issuance upon the exercise of Warrants, will be listed 
and maintained on the principal securities exchanges and markets within the 
United States of America, if any, on which other shares of Common Stock are 
then listed and registered under the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), or authorized for quotation on Nasdaq, 
provided, however, that the payment of any required listing or other fee 
shall always be deemed to be "commercially reasonable" for purposes of this 
Section 9.

         SECTION 10.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES
ISSUABLE.  
         
         (a)  In order to prevent the dilution of the rights granted under 
this Agreement, the Exercise Price shall be subject to adjustment from time 
to time as provided in this Section 10, and the number of shares of Common 
Stock obtainable upon exercise of the Warrants shall be subject to adjustment 
from time to time as provided in this Section 10.  For purposes of this 
Section 10, "Trigger Price" shall be $6.75 per share of Common Equity; 
"Convertible Security" means any stock or securities, directly or indirectly, 
convertible into or exchangeable for Common Equity, including without 
limitation any exchangeable debt securities; "Option" shall mean any rights 
or options to subscribe for or purchase Common Equity or Convertible 
Securities.
   
         (b)  If and whenever the Company issues or sells or, in accordance 
with Section 10(c), is deemed to have issued or sold, any share of Common 
Equity without consideration or for a net consideration per share less than 
the Trigger Price, then immediately upon such issuance or sale, the Exercise 
Price, which shall equal $10 per share until the first such issuance or sale 
below the Trigger Price, shall be reduced to the price per share determined 
by dividing (i) an amount equal to the sum of (A) the number of shares of 
Common Equity outstanding immediately prior to such issuance multiplied by 
the Exercise Price in effect immediately prior to such issuance, and (B) the 
consideration, if any, received by the Company upon such issuance, by (ii) 
the total number of shares of Common Equity outstanding immediately after 
such issuance.  
         
         Notwithstanding the foregoing, there shall be no adjustment to the 
Exercise Price with respect to the granting of, or issuance of Common Equity 
upon exercise of, stock options to employees of the Company authorized but 
not granted as of the Effective Date for an aggregate of up to 300,000 shares 
of Common Equity (as such shares are equitably adjusted for subsequent stock 
splits, stock combinations, stock dividends and recapitalizations).  For 
purposes of this Section 10, "Common Equity" means all 


                                      6

<PAGE>

shares now or hereafter authorized of any class of common stock of the 
Company (including the Common Stock) and any other stock of the Company, 
however designated, authorized on or after the date hereof, which has the 
right (subject always to prior rights of any class or series of preferred 
stock) to participate in any distribution of the assets or earnings of the 
Company without limit as to per share amount, and "Fully Diluted Equity" 
means, with respect to the Company at any given time, (A) the number of 
shares of Common Equity actually outstanding at such time, plus (B) the 
maximum number of shares of Common Equity that are issuable upon the 
exercise, exchange or conversion of any unexpired right or unexpired option 
(including the Warrants) to subscribe for, to purchase or to receive Common 
Equity or other securities convertible into or exchangeable for Common 
Equity, including without limitation any exchangeable debt securities, 
regardless of whether any of the foregoing are actually exercisable at such 
time; provided, however, the number of shares of Common Equity outstanding at 
any given time shall not include shares, directly or indirectly, owned or 
held by or for the account of the Company.
      
         (c)  For purposes of determining the adjusted Exercise Price under 
Section 10(b) above, the following shall be applicable:
      
              (1)  CONSIDERATION.  If any Common Equity, Options or Convertible
          Securities are issued or sold or deemed to have been issued or sold 
          for cash, the consideration received therefor shall be deemed to be 
          (i) in the case of any public offering of such securities for cash, 
          the gross proceeds of such offering (without deduction for any 
          underwriters discount) and (ii) in the case of any other issuance, 
          sale or deemed issuance or sale for cash, the gross amount received 
          by the Company therefor.  In case any Common Equity, Options or 
          Convertible Securities are issued or sold for a consideration other 
          than cash, the amount of the consideration other than cash received 
          by the Company shall be the fair market value of such consideration.
          In case any Common Equity, Options or Convertible Securities are 
          issued to the owners of the non-surviving entity in connection with 
          any merger in which the Company is the surviving corporation, the 
          amount of consideration therefor shall be deemed to be the fair 
          market value of such portion of the net assets and business of the 
          non-surviving entity as is attributable to such Common Equity, 
          Options or Convertible Securities, as the case may be.  The fair 
          market value of any consideration other than cash shall be 
          determined jointly by the Company and a majority in interest of the 
          Warrant Holders.  If such parties are unable to reach agreement 
          within a reasonable period of time, such fair market value shall be 
          determined by an appraiser reasonably selected by the Company and 
          reasonably approved by such Warrant Holders.  The determination of 
          such appraiser shall be final and binding on the Company and the 
          Warrant Holders, and the fees and expenses of such appraiser shall 
          be paid by the Company, unless the fair market value determined by 
          such appraiser is less than five percent (5%) above the value 
          proposed in writing by the Company and rejected by such Warrant 
          Holders prior to the selection of such appraiser, in which event the 
          fees and expenses of such appraiser shall be for such Warrant 
          Holders' account.

              (2)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the 
          granting or sale of any Option or Convertible Security (whether or 
          not at the time convertible, exercisable or exchangeable):

               (A)  the aggregate maximum number of shares of Common Equity 
               deliverable, directly or indirectly, upon exercise of any 
               Option shall be deemed to have been issued at the time such 
               Option was granted and for a consideration equal to the 
               consideration (determined in the manner provided in subsection 
               (1) above), if any, received by the Company upon the issuance 
               of 


                                      7

<PAGE>

               such Option plus the minimum purchase price provided in such 
               Option for the Common Equity covered thereby;

               (B)  the aggregate maximum number of shares of Common Equity 
               deliverable upon conversion of or in exchange for any such 
               Convertible Security, or upon the exercise of any Option to 
               purchase or acquire any Convertible Security and the subsequent 
               conversion or exchange thereof, shall be deemed to have been 
               issued at the time such Convertible Security was issued or such 
               Option was issued and for a consideration equal to the 
               consideration, if any, received by the Company for any such 
               Convertible Security and any related Option (excluding any cash 
               received on account of accrued interest or accrued dividends), 
               plus the additional consideration (determined in the manner 
               provided in subsection (1) above), if any, to be received by 
               the Company upon the conversion or exchange of such Convertible 
               Security, or upon the exercise of any related Option to purchase
               or acquire any Convertible Security and the subsequent 
               conversion or exchange thereof;

               (C)  on any change in the number of shares of Common Equity 
               deliverable, directly or indirectly, upon conversion, exercise 
               or exchange of any such Option or Convertible Security or any 
               change in the consideration to be received by the Company upon 
               such exercise, conversion or exchange, including, but not 
               limited to, a change resulting from the anti-dilution provisions
               thereof, the Exercise Price as then in effect shall forthwith 
               be readjusted to such Exercise Price as would have been obtained
               had an adjustment been made upon the issuance of such Option or 
               Convertible Security upon the basis of such change;and

               (D)  if the Exercise Price shall have been adjusted upon the 
               issuance of any such Option or Convertible Security, no further 
               adjustment of the Exercise Price shall be made for the actual 
               issuance of Common Equity upon any exercise, conversion, or 
               exchange thereof;

provided, however, that none of the events set forth in Section 10(c)(2)(A) 
through 10(c)(2)(D), inclusive, shall result in any increase in the Exercise 
Price.

     (3)  INTEGRATED TRANSACTION.  In case any Option is issued in connection 
with the issue or sale of other securities of the Company, together 
comprising one integrated transaction in which no specific consideration is 
allocated to such Options by the parties thereto, the Options shall be deemed 
to have been issued without consideration.

     (4)  TREASURY SHARES.  The number of shares of Common Equity outstanding 
at any given time does not include shares owned or held by or for the account 
of the Company, and the disposition of any shares so owned or held shall be 
considered an issuance or sale of Common Equity.

     (5)  RECORD DATE.  If the Company takes a record of the holders of 
Common Equity for the purpose of entitling them (A) to receive a dividend or 
other distribution payable in Common Equity, Options or in Convertible 
Securities or (B) to subscribe for or purchase 


                                      8
<PAGE>
 
          Common Equity, Options or Convertible Securities, then such record 
          date shall be deemed to be the date of the issuance or sale of the 
          shares of Common Equity deemed to have been issued or sold upon the 
          declaration of such dividend or the making of such other 
          distribution or the date of the granting of such right of 
          subscription or purchase, as the case may be.

         (d)  If the Company at any time subdivides (by any stock split, 
stock dividend, recapitalization or otherwise) one or more classes of its 
outstanding shares of Common Equity into a greater number of shares, the 
Exercise Price in effect immediately prior to such subdivision shall be 
proportionately reduced and the number of shares of Common Stock obtainable 
upon exercise of the Warrant shall be proportionately increased.  If the 
Company at any time combines (by reverse stock split or otherwise) one or 
more classes of its outstanding shares of Common Stock into a smaller number 
of shares, the Exercise Price in effect immediately prior to such combination 
shall be proportionately increased and the number of shares of Common Stock 
obtainable upon exercise of this Warrant shall be proportionately decreased.

         (e)  Any recapitalization, reorganization, reclassification, 
consolidation, merger, sale of all or substantially all of the Company's 
assets or other transaction, in each case which is effected in such a way 
that the holders of Common Equity are entitled to receive (either directly or 
upon subsequent liquidation) stock, securities or assets with respect to or 
in exchange for Common Equity is referred to herein as a "Corporate Change."  
Prior to the consummation of any Corporate Change, the Company shall make 
appropriate provision (in form and substance satisfactory to the Warrant 
Holder) to insure that the Warrant Holder shall thereafter have the right to 
acquire and receive, in lieu of or in addition to (as the case may be) the 
Warrant Shares acquirable and receivable upon the exercise of such holder's 
Warrants, such shares of stock, securities or assets as may be issued or 
payable with respect to or in exchange for the number of Warrant Shares 
acquirable and receivable upon exercise of such holder's Warrant had such 
Corporate Change not taken place.  In any such case, the Company shall make 
appropriate provision (in form and substance reasonably satisfactory to the 
Warrant Holder) with respect to such holder's rights and interests to insure 
that the provisions of this Agreement shall thereafter be applicable to the 
Warrants (including, in the case of any such consolidation, merger or sale in 
which the successor entity or purchasing entity is other than the Company, 
any adjustment of the Exercise Price based on Section 10 hereof).  The 
Company shall not effect any such consolidation, merger or sale, unless prior 
to the consummation thereof, the successor entity (if other than the Company) 
resulting from consolidation or merger or the entity purchasing such assets 
assumes by written instrument (in form and substance reasonably satisfactory 
to the Warrant Holder), the obligation to deliver to the Warrant Holder such 
shares of stock, securities or assets as, in accordance with the foregoing 
provisions, such holder may be entitled to acquire.
         
        (f)  If any event occurs of the type contemplated by the provisions 
of this Section 10 but not expressly provided for by such provisions 
(including, without limitation, the granting of stock appreciation rights, 
phantom stock rights or other rights with equity features), then the 
Company's Board shall make an appropriate adjustment in the Exercise Price 
and the number of shares of Common Stock obtainable upon exercise of this 
Warrant so as to protect the rights of the Warrant Holder; provided that no 
such adjustment shall increase the Exercise Price or decrease the number of 
shares of Common Stock obtainable as otherwise determined pursuant to this 
Section 10.
      
      (g)  If the Company declares or pays a dividend upon the Common Equity 
payable otherwise than in cash out of earnings or earned surplus (determined 
in accordance with generally accepted accounting principles, consistently 
applied) except for a stock dividend payable in shares of Common Stock (a 
"Liquidating Dividend"), then the Company shall pay to the Warrant Holder at 
the time of


                                      9

<PAGE>

payment thereof the Liquidating Dividend which would have been paid to such
Warrant Holder on the Common Stock had the Warrants been fully exercised
immediately prior to the date on which a record is taken for such Liquidating
Dividend, or, if no record is taken, the date as of which the record holders of
Common Equity entitled to such dividends are to be determined.

               SECTION 11.  FRACTIONAL INTERESTS. 

               The Company shall not be required to issue fractional Warrant 
Shares upon the exercise of Warrants.  If more than one Warrant shall be 
presented for exercise in full at the same time by the Warrant Holder, the 
number of full Warrant Shares which shall be issuable upon the exercise 
thereof shall be computed on the basis of the aggregate number of Warrant 
Shares purchasable on exercise of the Warrants so presented.  If any fraction 
of a Warrant Share would, except for the provisions of this Section 11, be 
issuable on the exercise of any Warrants (or specified portion thereof), the 
Company shall pay an amount in cash equal to the "fair market value" 
(determined as provided in Section 5(a) above) of the Common Stock on the day 
immediately preceding the date the Warrant is presented for exercise, 
multiplied by such fraction.

               SECTION 12.  FINANCIAL STATEMENTS.

               (a)  Whether or not required by the rules and regulations of 
the Securities and Exchange Commission (the "Commission"), so long as any of 
the Warrants remain outstanding, the Company shall furnish to the Warrant 
Holders (i) all quarterly and annual financial information that would be 
required to be contained in a filing with the Commission on Forms 10-Q and 
10-K if the Company were required to file such Forms, including "Management's 
Discussion and Analysis of Financial Condition and Results of Operations" 
and, with respect to the annual information only, a report thereon by the 
Company's certified independent accountants and (ii) all current reports that 
would be required to be filed with the Commission on Form 8-K if the Company 
were required to file such reports. In addition, whether or not required by 
the rules and regulations of the Commission, the Company shall file a copy of 
all such information and reports with the Commission for public availability 
(unless the Commission will not accept such a filing).

               (b)  The Company shall, so long as any of the Warrants are 
outstanding, deliver to the Warrant Holders, forthwith upon any Executive 
Officer of the Corporation becoming aware of any default under this 
Agreement, an Officers' Certificate specifying such default and what action 
the Company is taking or proposes to take with respect thereto.

               SECTION 13.  NOTICES TO WARRANT HOLDERS.  

               (a)  Upon any adjustment of the Exercise Price or exercise 
privileges pursuant to Section 10, the Company shall promptly thereafter (i) 
cause to be filed with the Company a certificate of a firm of independent 
public accountants of recognized standing, selected by the Board (who may be 
the regular auditors of the Company) and acceptable to the Warrant Holders, 
setting forth the Exercise Price after such adjustment and setting forth in 
reasonable detail the method of calculation and the facts upon which such 
calculations are based and setting forth the number of Warrant Shares (or 
portion thereof) issuable after such adjustment in the Exercise Price, which 
certificate shall be conclusive evidence of the correctness of the matters 
set forth therein, upon exercise of a Warrant and payment of the adjusted 
Exercise Price, and (ii) cause to be given to each of the registered holders 
of the Warrant Certificate(s), at his or her address appearing on the Warrant 
register, written notice of such adjustments by first-class 


                                       10

mail, postage prepaid.  Where appropriate, such notice may be given in 
advance and included as a part of the notice required to be mailed under the 
other provisions of this Section 13.

               (b)  In case:

                    (1)  the Company shall authorize the issuance to all holders
               of shares of Common Stock of the Company rights to subscribe for,
               or to purchase shares of, Common Stock or of any other 
               subscription rights or warrants; or

                    (2)  the Company shall authorize the distribution to all 
               holders of shares of Common Stock of evidences of its 
               indebtedness or assets; or

                    (3)  of any consolidation or merger to which the Company is
               a party and for which approval of any shareholders of the Company
               is required, or of the conveyance or transfer of the properties 
               and assets of the Company substantially as an entirety, or of 
               any reclassification or change of Common Stock issuable upon 
               exercise of the Warrants, or a tender offer or exchange offer 
               for shares of Common Stock; or

                    (4)  of the voluntary or involuntary dissolution, 
               liquidation or winding up of the Company or a Liquidating 
               Dividend; or

                    (5)  the Company proposes to take any action which would 
               require an adjustment of the Exercise Price or the Warrant 
               Shares pursuant to Section 10;

then the Company shall cause to be given to each of the registered holders of 
the Warrant Certificates at his or her address appearing on the Warrant 
register, at least twenty (20) days prior to the applicable record date 
hereinafter specified, or promptly in the case of events for which there is 
no record date, by first-class mail, postage prepaid, a written notice 
stating (i) the date as of which the holders of record of shares of Common 
Stock to be entitled to receive any such rights or distribution are to be 
determined, or (ii) the initial expiration date set forth in any tender offer 
or exchange offer for shares of Common Stock, or (iii) the date on which any 
such consolidation, merger, conveyance, transfer, dissolution, liquidation or 
winding up is expected to become effective or consummated, and the date as of 
which it is expected that holders of record of shares of Common Stock shall 
be entitled to exchange such shares for securities or other property, if any, 
deliverable upon such reclassification, consolidation, merger, conveyance, 
transfer, dissolution, liquidation or winding up.  The failure to give the 
notice required by this Section 13 or any defect therein shall not affect the 
legality or validity of any distribution, right, option, warrant, 
consolidation, merger, conveyance, transfer, dissolution, liquidation or 
winding up, or the vote upon any action.

               (c)  Nothing contained in this Agreement or in the Warrant 
Certificate shall be construed as conferring upon the holders thereof the 
right to vote or to consent or to receive notice as shareholders in respect 
of the meetings of shareholders or the election of Directors of the Company 
or any other matter, or any rights whatsoever as shareholders of the Company.

               SECTION 14.  NOTICES TO THE COMPANY AND THE WARRANT HOLDERS. 

               (a)  Unless otherwise provided herein, any notice, request, 
instruction or other document to be given hereunder by any party to the other 
shall be in writing and delivered by hand-delivery, registered first-class 
mail, return receipt requested, facsimile or air courier guaranteeing 
overnight delivery, as follows:

               This Agreement and each Warrant Certificate issued hereunder

                            [FORM OF WARRANT CERTIFICATE]

                                      [REVERSE]

     The Warrants evidenced by this Warrant Certificate are part of a duly 
authorized issue of Warrants expiring on the Expiration Date, entitling the 
holder on exercise to receive shares of Common Stock, $.001 par value, of the 
Company (the "Common Stock"), and are issued or to be issued pursuant to the 
Warrant Agreement, duly executed and delivered by the Company, which Warrant 
Agreement is hereby incorporated by reference in and made a part of this 
instrument and is hereby referred to for a description of the rights, 
limitation of rights, obligations, duties and immunities thereunder of the 
Company and the holders (the words "holders" or "holder" meaning the 
registered holders or registered holder) of the Warrants (the "Warrant 
Holders"). A copy of the Warrant Agreement may be obtained by the holder 
hereof upon written request to the Company.

     Warrants may be exercised at any time on or before the Expiration Date. 
The holder of Warrants evidenced by this Warrant Certificate may exercise 
them by surrendering this Warrant Certificate, with the form of election to 
purchase set forth herein properly completed and executed, together with 
payment of the Exercise Price in cash at the office of the Company designated 
for such purpose. In the alternative, each Warrant Holder may exercise its 
right, during the Exercise Period, as defined in the Warrant Agreement, to 
receive Warrant Shares on a net basis, such that, without the exchange of any 
funds, the Warrant Holder receives that number of Warrant Shares otherwise 
issuable (or payable) upon exercise of its Warrants less that number of 
Warrant Shares having an aggregate fair market value (as defined below) at 
the time of exercise equal to the aggregate Exercise Price that would 
otherwise have been paid by the Warrant Holder of the Warrant Shares.  For 
purposes of the foregoing sentence, "fair market value" of the Warrant Shares 
will be determined in the manner set forth in the Warrant Agreement.  In the 
event that upon any exercise of Warrants evidenced hereby the number of 
Warrants exercised shall be less than the total number of Warrants evidenced 
hereby, there shall be issued to the holder hereof or his assignee a new 
Warrant Certificate evidencing the number of Warrants not exercised. Except 
as provided in Section 10 of the Warrant Agreement, no adjustment shall be 
made for any dividends on any Common Stock issuable upon exercise of this 
Warrant.

     The Warrant Agreement provides that, upon the occurrence of certain 
events, the Exercise Price and the number of Warrant Shares set forth on the 
face hereof may, subject to certain conditions, be adjusted. No fractions of 
a share of Common Stock will be issued upon the exercise of any Warrant, but 
the Company will pay the cash value thereof determined as provided in the 
Warrant Agreement. 

     The holders of the Warrants are entitled to certain registration rights 
with respect to the Common Stock purchasable upon exercise thereof.  Said 
registration rights are set forth in full in a Registration Rights Agreement 
dated as of October 14, 1997, between the Company and the Warrant Holder.  A 
copy of the Registration Rights may be obtained by the holder hereof upon 
written request to the Company.

     Warrant Certificates, when surrendered at the office of the Company by 
the registered holder thereof in person or by legal representative or 
attorney duly authorized in writing, may be exchanged, in the manner and 
subject to the limitations provided in the Warrant Agreement, but without 
payment of any service charge, for another Warrant Certificate or Warrant 
Certificates of like tenor evidencing in the aggregate a like number of 
Warrants.

                                      iii
<PAGE>

     Upon due presentation for registration of transfer of this Warrant 
Certificate at the office of the Company, a new Warrant Certificate or 
Warrant Certificates of like tenor and evidencing in the aggregate a like 
number of Warrants shall be issued to the transferee(s) in exchange for this 
Warrant Certificate, subject to the limitations provided in the Warrant 
Agreement, without charge except for any tax or other governmental charge 
imposed in connection therewith.

     The Company may deem and treat the registered holder(s) thereof as the 
absolute owner(s) of this Warrant Certificate (notwithstanding any notation 
of ownership or other writing hereon made by anyone), for the purpose of any 
exercise hereof, of any distribution to the holder(s) hereof, and for all 
other purposes, and the Company shall not be affected by any notice to the 
contrary. Neither the Warrants nor this Warrant Certificate entitles any 
holder hereof to any rights of a stockholder of the Company.

"Carlyle Investors"), dated as of October 14, 1997, pursuant to which the 
Company agrees, among other things, to issue to the Carlyle Investors

of two hundred fifty hundred thousand (250,000) shares of Common Stock of the 
Company.  Each Warrant shall be a warrant to purchase one (1) Warrant Share, 
unless and until adjusted pursuant to Section 10 hereof.  Certain terms used 
herein and not elsewhere defined are defined in the Purchase Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual 
agreements herein set forth, and for other good and lawful consideration, the 
receipt, sufficiency and adequacy of which are hereby acknowledged, the 
parties hereto agree as follows:

         SECTION 1.     WARRANT CERTIFICATE. 

         The certificates evidencing the Warrants (the "Warrant 
Certificates") to be delivered pursuant to this Agreement shall be in 
registered form only and shall be substantially in the form set forth in 
Exhibit A attached hereto.

         SECTION 2.     EXECUTION OF WARRANT CERTIFICATE. 

         (a)  The Warrant Certificates shall be signed on behalf of the 
Company by its Chairman of the Board of Directors (the "Board") or its 
President or a Vice President, and by its Secretary or an Assistant Secretary 
under its corporate seal.  Each such signature upon the Warrant Certificates 
may be in the form of a facsimile signature of the present or any future

reproduced on the Warrant Certificates.  The seal of the Company may be in 
the form of a facsimile thereof and may be impressed, affixed, imprinted or 
otherwise reproduced on the Warrant Certificates.

         (b)  In case any officer of the Company who shall have signed any 
Warrant Certificate shall cease to be such officer before the Warrant 
Certificate so signed shall have been disposed of by the Company, such 
Warrant Certificate nevertheless may be delivered or disposed of as though 
such person had not ceased to be such officer of the Company; and any Warrant 
Certificate may be signed on behalf of the Company by any person who, at the 
actual date of the execution of such Warrant Certificate, shall be a proper 
officer of the Company to sign such Warrant Certificate, although at the date 
of the execution of this Agreement any such person was not such an officer.

         SECTION 3.     REGISTRATION.

         The Company shall register the Warrant Certificates in a Warrant 
register to be maintained by the Company (the "Warrant Register") when 
Warrants are issued. The Company may deem and treat the registered holders of 
the Warrant Certificates as the absolute owners thereof (notwithstanding any 
notation of ownership or other writing thereon made by anyone) for all 
purposes and shall not be affected by any notice to the contrary.

         SECTION 4.     REGISTRATION OF TRANSFERS AND EXCHANGES.  

         (a)  The Company shall from time to time register the transfer of 
any outstanding Warrant Certificate in the Warrant Register upon surrender 
thereof accompanied by a written instrument or instruments of transfer in 
form satisfactory to the Company, duly executed by the registered holder or 
holders thereof or by the duly appointed legal representative thereof or by a 
duly authorized attorney. Upon any such registration of transfer, a new 
Warrant Certificate shall be issued to the transferee and the surrendered 
Warrant Certificate shall be canceled and disposed of by the Company.

         (b)  The Warrant Holder agrees that prior to any proposed transfer 
of the Warrants or of the Warrant Shares, which transfer shall not be to any 
Person engaged in the Business, if such transfer is not made pursuant to an 
effective Registration Statement under the Securities Act of 1933, as amended 
(the "Securities Act"), the Warrant Holder will, if requested by the Company, 
deliver to the Company:

              (1)  an investment representation letter reasonably 
          satisfactory to the Company signed by the proposed transferee;

              (2)  an agreement by such transferee to the impression of the 
          restrictive investment legend set forth below in Section 4(c) on 
          the Warrants or the Warrant Shares;

              (3)  an agreement by such transferee that the Company may place 
          a notation in the stock books of the Company or a "stop transfer 
          order" with any transfer agent or registrar with respect to the 
          Warrant Shares;

              (4)  an agreement by such transferee to be bound by the 
          provisions of this Section 4 relating to the transfer of such 
          Warrants or Warrant Shares; and

              (5)  except in the case of a transfer pursuant to Rule 144 
          promulgated pursuant to the Securities Act, or any successor rule, 
          prior to consummating any private sale or transfer of such Warrants 
          or Warrant Shares, the written opinion of reputable legal counsel 
          in form reasonably


                                      2

<PAGE>

          acceptable to the Company that such sale or transfer is being made 
          in compliance with applicable federal securities laws.

          (c)  The Warrant Holder agrees that each certificate representing 
Warrants or Warrant Shares will bear the following legend until such Warrants 
or Warrant Shares have been sold pursuant to an effective registration 
statement under the Securities Act:

               "THE SECURITIES EVIDENCED OR CONSTITUTED HEREBY HAVE BEEN 
               ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED 
               UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH 
               SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED, 
               HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF 
               REGISTRATION UNDER SAID ACT AND THE RULES AND REGULATIONS 
               THEREUNDER AND OF ALL APPLICABLE STATE SECURITIES OR 
               "BLUE SKY" LAWS OR AN EXEMPTION THEREFROM UNDER SAID ACT 
               AND ALL APPLICABLE STATE SECURITIES OR "BLUE SKY" LAWS.  
               IN THE CASE OF A SALE OF THE SECURITIES EVIDENCED OR 
               CONSTITUTED HEREBY, OTHER THAN A SALE PURSUANT TO A VALID 
               REGISTRATION STATEMENT UNDER SAID ACT OR A SALE PURSUANT 
               TO RULE 144 PROMULGATED UNDER SAID ACT, THE HOLDER OF THE 
               SECURITIES EVIDENCED OR CONSTITUTED HEREBY SHALL PROVIDE 
               TO THE CORPORATION THE WRITTEN OPINION OF REPUTABLE LEGAL 
               COUNSEL IN FORM REASONABLY ACCEPTABLE TO THE CORPORATION 
               THAT SUCH SALE OR TRANSFER IS BEING MADE IN COMPLIANCE 
               WITH APPLICABLE FEDERAL SECURITIES LAWS."

         (d)  A Warrant Certificate may be exchanged at the option of the 
holder thereof, when surrendered to the Company at its office for another 
Warrant Certificate or other Warrant Certificates of like tenor and 
representing in the aggregate a like number of Warrants.  A Warrant 
Certificate surrendered for exchange shall be canceled and disposed of by the 
Company

         SECTION 5.     WARRANTS; EXERCISE OF WARRANTS.  

         (a)  Subject to the terms of this Agreement, the Warrant Holder 
shall have the right, which may be exercised during the period commencing on 
the Effective Date until 5:00 p.m., Washington, D.C. time, on the fifth 
anniversary of the Effective Date (the "Exercise Period"), to receive from 
the Company the number of fully paid and non-assessable Warrant Shares that 
the Warrant Holder may at the time be entitled to receive on exercise of the 
number of Warrants that the Warrant Holder elects to exercise and payment of 
the Exercise Price (as defined below) then in effect for such Warrant Shares. 
In the alternative, the Warrant Holder may exercise its right, during the 
Exercise Period, to receive Warrant Shares on a net basis, such that, without 
payment of any funds kind, the Warrant Holder receives that number of Warrant 
Shares equal to the number of Warrants being exercised times the quotient of 
(i) the "fair market value" of a Warrant Share (as defined below) minus the 
Exercise Price, divided by (ii) the fair market value of a Warrant Share.  
For purposes of the foregoing sentence, "fair market value" of a Warrant 
Share shall mean the average of the closing prices of the Common Stock's 
sales on all domestic 


                                      3

<PAGE>

securities exchanges on which such Common Stock may at the time be listed, 
or, if there have been no sales on any such exchange on any day, the average 
of the highest bid and lowest asked prices on all such exchanges at the end 
of such day, or, if on any day such Common Stock is not so listed, the 
average of the representative bid and asked prices quoted on Nasdaq as of 
4:00 P.M., New York time, on such day, or, if on any day such Common Stock is 
not quoted on Nasdaq, the average of the highest bid and lowest asked prices 
on such day in the domestic over-the-counter market as reported by the 
National Quotation Bureau, Incorporated, or any similar successor 
organization, in each such case averaged over a period of twenty-one (21) 
business days consisting of the day as of which the "fair market value" of 
the Warrant Shares is being determined and the twenty (20) consecutive 
business days prior to such day; provided that if such Common Stock is listed 
on any domestic securities exchange the term "business days" as used in this 
sentence means business days on which such exchange is open for trading.  If 
at any time such Common Stock is not listed on any domestic securities 
exchange or quoted on Nasdaq or the domestic over-the-counter market, the 
"fair market value" of the Warrant Shares shall be the fair value thereof 
determined by the Company and approved by the Warrant Holder; provided that 
if such parties are unable to reach agreement within a reasonable period of 
time, such fair market value shall be determined by an appraiser reasonably 
selected by the Company and reasonably approved by the Warrant Holder.  The 
determination of such appraiser shall be final and binding on the Company and 
the Warrant Holder, and the fees and expenses of such appraiser shall be paid 
by the Company, unless the fair market value determined by such appraiser is 
less than five percent (5%) above the value proposed in writing by the 
Company and rejected by the Warrant Holder prior to the selection of such 
appraiser, in which event the fees and expenses of such appraiser shall be 
for the Warrant Holder's account.  Each Warrant not exercised prior to 5:00 
p.m., Washington, D.C. time, on the fifth anniversary of the Effective Date 
shall become void and all rights thereunder and all rights in respect thereof 
under this agreement shall cease as of such time.  No adjustments as to 
dividends will be made upon exercise of the Warrants.

         (b)  A Warrant may be exercised upon surrender to the Company at its 
office designated for such purpose (the address of which is set forth in 
Section 14 hereof) of the certificate or certificates evidencing the Warrants 
to be exercised with the form of election to purchase on the reverse thereof 
duly filled in and signed, and upon (i) payment to the Company of the 
exercise price of ten dollars ($10.00) per Warrant Share, as adjusted as 
herein provided (as so adjusted, the "Exercise Price"), for the number of 
Warrant Shares in respect of which such Warrants are then exercised, or (ii) 
the Warrant Holder's exercise of its right to receive Warrant Shares on a net 
basis, as more fully described in Section 5(a).  Payment of the aggregate 
Exercise Price shall be made (i) in cash or by certified or official bank 
check payable to the order of the Company or (ii) in the manner provided in 
subsection (a) of this Section 5.

         (c)  Subject to the provisions of Section 6 hereof, upon such 
surrender of Warrants and payment of the Exercise Price, the Company shall 
issue and cause to be delivered with all reasonable dispatch to or upon the 
written order of the Warrant Holder and in such name or names as the Warrant 
Holder may designate, a certificate or certificates for the number of full 
Warrant Shares issuable upon the exercise of such Warrants together with cash 
as provided in Section 11; PROVIDED, HOWEVER, that if any consolidation, 
merger, or sale or other transfer of all or substantially all of the assets 
of the Company is proposed to be effected by the Company, or a tender offer 
or an exchange offer for shares of Common Stock of the Company shall be made, 
upon such surrender of Warrants and payment of the Exercise Price as 
aforesaid, the Company shall, as soon as practicable, but in any event not 
later than five business days thereafter, issue and cause to be delivered the 
full number of Warrant Shares issuable upon the exercise of such Warrants in 
the manner described in this sentence together with cash as provided in 
Section 11.  Such certificate or certificates shall be deemed to have been 
issued and any person so designated to be named therein shall be deemed to 
have become a holder of record of such Warrant Shares as of the date of the 
surrender of such Warrants and payment of the Exercise Price.


                                      4

         (d)  The Warrants shall be exercisable, at the election of the 
holder thereof, either in full or from time to time in part and, in the event 
that a Warrant Certificate evidencing Warrants is exercised in respect of 
fewer than all of the Warrant Shares issuable on such exercise at any time 
prior to the date of expiration of the Warrants, a new Warrant Certificate 
evidencing the remaining Warrant or Warrants will be issued and delivered by 
the Company and at its expense pursuant to the provisions of this Section and 
of Section 2 hereof.

         (e)  All Warrant Certificates surrendered upon exercise of Warrants 
shall be canceled and disposed of by the Company. The Company shall keep 
copies of this Agreement and any notices given or received hereunder 
available for inspection by the Warrant Holder during normal business hours 
at its office.

         SECTION 6.     PAYMENT OF TAXES. 

         The Company will pay all documentary stamp taxes or other similar 
taxes attributable to the initial issuance of Warrant Shares upon the 
exercise of Warrants; PROVIDED, HOWEVER, that the Company shall not be 
required to pay any tax or taxes which may be payable in respect of any 
transfer involved in the issue of any Warrant Certificate or any certificates 
for Warrant Shares in a name other than that of the registered holder of a 
Warrant Certificate surrendered upon the exercise of a Warrant, and the 
Company shall not be required to issue or deliver such Warrant Certificates 
unless or until the person or persons requesting the issuance thereof shall 
have paid to the Company the amount of such tax or shall have established to 
the satisfaction of the Company that such tax has been paid.

         SECTION 7.     MUTILATED OR MISSING WARRANT CERTIFICATES.  

         In case any of the Warrant Certificates shall be mutilated, lost, 
stolen or destroyed, the Company may issue, in exchange and substitution for, 
and upon cancellation of, the mutilated Warrant Certificate, or in lieu of 
and substitution for the Warrant Certificate lost, stolen or destroyed, a new 
Warrant Certificate of like tenor and representing an equivalent number of 
Warrants, but only upon receipt of evidence reasonably satisfactory to the 
Company of such loss, theft or destruction of such Warrant Certificate and 
indemnity, if requested, also reasonably satisfactory to it. Applicants for 
such substitute Warrant Certificates shall also comply with such other 
reasonable regulations and pay such other reasonable charges as the Company 
may prescribe.

         SECTION 8.     RESERVATION OF WARRANT SHARES. 

         (a)  The Company will at all times reserve and keep available, free 
from preemptive rights, out of the aggregate of its authorized but unissued 
Common Stock or its authorized and issued Common Stock held in its treasury, 
for the purpose of enabling it to satisfy any obligation to issue Warrant 
Shares upon exercise of Warrants, the maximum number of shares of Common 
Stock which may then be deliverable upon the exercise of all outstanding 
Warrants.

         (b)  The Company or, if appointed, the transfer agent for the Common 
Stock (the "Transfer Agent") and every subsequent Transfer Agent for any 
shares of the Company's capital stock issuable upon the exercise of any of 
the rights of purchase aforesaid will be irrevocably authorized and directed 
at all times to reserve such number of authorized shares as shall be required 
for such purpose. The Company will keep a copy of this Agreement on file with 
the Transfer Agent and with every subsequent transfer agent for any shares of 
the Company's capital stock issuable upon the exercise of the rights of 
purchase 

                                      5

<PAGE>
represented by the Warrants.  The Company will furnish such Transfer 
Agent a copy of all notices of adjustments and certificates related thereto 
transmitted to each holder pursuant to Section 13 hereof.

         (c)  Before taking any action which would cause an adjustment 
pursuant to Section 10 hereof to reduce the Exercise Price below the then par 
value (if any) of the Warrant Shares, the Company will take any corporate 
action which may, in the opinion of its counsel (which may be counsel 
employed by the Company), be necessary in order that the Company may validly 
and legally issue fully paid and nonassessable Warrant Shares at the Exercise 
Price as so adjusted.

         (d)  The Company covenants that all Warrant Shares which may be 
issued upon exercise of Warrants will, upon issue, be fully paid, 
nonassessable, free of preemptive rights and free from all taxes, liens, 
charges and security interests with respect to the issue thereof.

         SECTION 9.     STOCK EXCHANGE LISTINGS. 

         The Company will from time to time take all commercially reasonable 
action, at its expense, which may be necessary so that the Warrant Shares, 
immediately upon their issuance upon the exercise of Warrants, will be listed 
and maintained on the principal securities exchanges and markets within the 
United States of America, if any, on which other shares of Common Stock are 
then listed and registered under the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), or authorized for quotation on Nasdaq, 
provided, however, that the payment of any required listing or other fee 
shall always be deemed to be "commercially reasonable" for purposes of this 
Section 9.

         SECTION 10.  ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES
ISSUABLE.  

         (a)  In order to prevent the dilution of the rights granted under 
this Agreement, the Exercise Price shall be subject to adjustment from time 
to time as provided in this Section 10, and the number of shares of Common 
Stock obtainable upon exercise of the Warrants shall be subject to adjustment 
from time to time as provided in this Section 10.  For purposes of this 
Section 10, "Trigger Price" shall be $6.75 per share of Common Equity; 
"Convertible Security" means any stock or securities, directly or indirectly, 
convertible into or exchangeable for Common Equity, including without 
limitation any exchangeable debt securities; "Option" shall mean any rights 
or options to subscribe for or purchase Common Equity or Convertible 
Securities.

         (b)  If and whenever the Company issues or sells or, in accordance 
with Section 10(c), is deemed to have issued or sold, any share of Common 
Equity without consideration or for a net consideration per share less than 
the Trigger Price, then immediately upon such issuance or sale, the Exercise 
Price, which shall equal $10 per share until the first such issuance or sale 
below the Trigger Price, shall be reduced to the price per share determined 
by dividing (i) an amount equal to the sum of (A) the number of shares of 
Common Equity outstanding immediately prior to such issuance multiplied by 
the Exercise Price in effect immediately prior to such issuance, and (B) the 
consideration, if any, received by the Company upon such issuance, by (ii) 
the total number of shares of Common Equity outstanding immediately after 
such issuance.  

         Notwithstanding the foregoing, there shall be no adjustment to the 
Exercise Price with respect to the granting of, or issuance of Common Equity 
upon exercise of, stock options to employees of the Company authorized but 
not granted as of the Effective Date for an aggregate of up to 300,000 shares 
of Common Equity (as such shares are equitably adjusted for subsequent stock 
splits, stock combinations, stock dividends and recapitalizations).  For 
purposes of this Section 10, "Common Equity" means all 


                                      6

<PAGE>

shares now or hereafter authorized of any class of common stock of the 
Company (including the Common Stock) and any other stock of the Company, 
however designated, authorized on or after the date hereof, which has the 
right (subject always to prior rights of any class or series of preferred 
stock) to participate in any distribution of the assets or earnings of the 
Company without limit as to per share amount, and "Fully Diluted Equity" 
means, with respect to the Company at any given time, (A) the number of 
shares of Common Equity actually outstanding at such time, plus (B) the 
maximum number of shares of Common Equity that are issuable upon the 
exercise, exchange or conversion of any unexpired right or unexpired option 
(including the Warrants) to subscribe for, to purchase or to receive Common 
Equity or other securities convertible into or exchangeable for Common 
Equity, including without limitation any exchangeable debt securities, 
regardless of whether any of the foregoing are actually exercisable at such 
time; provided, however, the number of shares of Common Equity outstanding at 
any given time shall not include shares, directly or indirectly, owned or 
held by or for the account of the Company.

         (c)  For purposes of determining the adjusted Exercise Price under 
Section 10(b) above, the following shall be applicable:

              (1)  CONSIDERATION.  If any Common Equity, Options or Convertible
          Securities are issued or sold or deemed to have been issued or sold 
          for cash, the consideration received therefor shall be deemed to be 
          (i) in the case of any public offering of such securities for cash, 
          the gross proceeds of such offering (without deduction for any 
          underwriters discount) and (ii) in the case of any other issuance, 
          sale or deemed issuance or sale for cash, the gross amount received 
          by the Company therefor.  In case any Common Equity, Options or 
          Convertible Securities are issued or sold for a consideration other 
          than cash, the amount of the consideration other than cash received 
          by the Company shall be the fair market value of such consideration.  
          In case any Common Equity, Options or Convertible Securities are 
          issued to the owners of the non-surviving entity in connection with 
          any merger in which the Company is the surviving corporation, the 
          amount of consideration therefor shall be deemed to be the fair 
          market value of such portion of the net assets and business of the 
          non-surviving entity as is attributable to such Common Equity, 
          Options or Convertible Securities, as the case may be.  The fair 
          market value of any consideration other than cash shall be 
          determined jointly by the Company and the Warrant Holder.  If such 
          parties are unable to reach agreement within a reasonable period of 
          time, such fair market value shall be determined by an appraiser 
          reasonably selected by the Company and reasonably approved by the 
          Warrant Holder.  The determination of such appraiser shall be final 
          and binding on the Company and the Warrant Holder, and the fees and 
          expenses of such appraiser shall be paid by the Company, unless the 
          fair market value determined by such appraiser is less than five 
          percent (5%) above the value proposed in writing by the Company and 
          rejected by the Warrant Holder prior to the selection of such 
          appraiser, in which event the fees and expenses of such appraiser 
          shall be for the Warrant Holder's account.  

              (2)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of 
          the granting or sale of any Option or Convertible Security 
          (whether or not at the time convertible, exercisable or 
          exchangeable):

                   (A)  the aggregate maximum number of shares of Common 
                    Equity deliverable, directly or indirectly, upon 
                    exercise of any Option shall be deemed to have been 
                    issued at the time such Option was granted and for a 
                    consideration equal to the consideration (determined 
                    in the manner provided in subsection (1) above), if 
                    any, received by the Company upon the issuance of 

                                      7

<PAGE>

                    such Option plus the minimum purchase price provided in 
                    such Option for the Common Equity covered thereby;

                    (B)  the aggregate maximum number of shares of 
                    Common Equity deliverable upon conversion of or in 
                    exchange for any such Convertible Security, or upon 
                    the exercise of any Option to purchase or acquire 
                    any Convertible Security and the subsequent 
                    conversion or exchange thereof, shall be deemed to 
                    have been issued at the time such Convertible 
                    Security was issued or such Option was issued and 
                    for a consideration equal to the consideration, if 
                    any, received by the Company for any such 
                    Convertible Security and any related Option 
                    (excluding any cash received on account of accrued 
                    interest or accrued dividends), plus the additional 
                    consideration (determined in the manner provided in 
                    subsection (1) above), if any, to be received by the 
                    Company upon the conversion or exchange of such 
                    Convertible Security, or upon the exercise of any 
                    related Option to purchase or acquire any 
                    Convertible Security and the subsequent conversion 
                    or exchange thereof;

                    (C)  on any change in the number of shares of Common 
                    Equity deliverable, directly or indirectly, upon 
                    conversion, exercise or exchange of any such Option 
                    or Convertible Security or any change in the 
                    consideration to be received by the Company upon 
                    such exercise, conversion or exchange, including, 
                    but not limited to, a change resulting from the 
                    anti-dilution provisions thereof, the Exercise Price 
                    as then in effect shall forthwith be readjusted to 
                    such Exercise Price as would have been obtained had 
                    an adjustment been made upon the issuance of such 
                    Option or Convertible Security upon the basis of 
                    such change; and

                    (D)  if the Exercise Price shall have been adjusted 
                    upon the issuance of any such Option or Convertible 
                    Security, no further adjustment of the Exercise 
                    Price shall be made for the actual issuance of 
                    Common Equity upon any exercise, conversion, or 
                    exchange thereof;

          provided, however, that none of the events set forth in Section 
          10(c)(2)(A) through 10(c)(2)(D), inclusive, shall result in any 
          increase in the Exercise Price.

              (3)  INTEGRATED TRANSACTION.  In case any Option is issued in 
          connection wit+h the issue or sale of other securities of the 
          Company, together comprising one integrated transaction in which no 
          specific consideration is allocated to such Options by the parties 
          thereto, the Options shall be deemed to have been issued without 
          consideration.

              (4)  TREASURY SHARES.  The number of shares of Common Equity 
          outstanding at any given time does not include shares owned or held 
          by or for the account of the Company, and the disposition of any 
          shares so owned or held shall be considered an issuance or sale of 
          Common Equity.

              (5)  RECORD DATE.  If the Company takes a record of the holders 
          of Common Equity for the purpose of entitling them (A) to receive a 
          dividend or other distribution payable in Common Equity, Options or 
          in Convertible Securities or (B) to subscribe for or purchase 

                                      8

<PAGE>

          Common Equity, Options or Convertible Securities, then such record 
          date shall be deemed to be the date of the issuance or sale of the 
          shares of Common Equity deemed to have been issued or sold upon the 
          declaration of such dividend or the making of such other 
          distribution or the date of the granting of such right of 
          subscription or purchase, as the case may be.

         (d)  If the Company at any time subdivides (by any stock split, 
stock dividend, recapitalization or otherwise) one or more classes of its 
outstanding shares of Common Equity into a greater number of shares, the 
Exercise Price in effect immediately prior to such subdivision shall be 
proportionately reduced and the number of shares of Common Stock obtainable 
upon exercise of the Warrant shall be proportionately increased.  If the 
Company at any time combines (by reverse stock split or otherwise) one or 
more classes of its outstanding shares of Common Stock into a smaller number 
of shares, the Exercise Price in effect immediately prior to such combination 
shall be proportionately increased and the number of shares of Common Stock 
obtainable upon exercise of this Warrant shall be proportionately decreased.

         (e)  Any recapitalization, reorganization, reclassification, 
consolidation, merger, sale of all or substantially all of the Company's 
assets or other transaction, in each case which is effected in such a way 
that the holders of Common Equity are entitled to receive (either directly or 
upon subsequent liquidation) stock, securities or assets with respect to or 
in exchange for Common Equity is referred to herein as a "Corporate Change."  
Prior to the consummation of any Corporate Change, the Company shall make 
appropriate provision (in form and substance satisfactory to the Warrant 
Holder) to insure that the Warrant Holder shall thereafter have the right to 
acquire and receive, in lieu of or in addition to (as the case may be) the 
Warrant Shares acquirable and receivable upon the exercise of such holder's 
Warrants, such shares of stock, securities or assets as may be issued or 
payable with respect to or in exchange for the number of Warrant Shares 
acquirable and receivable upon exercise of such holder's Warrant had such 
Corporate Change not taken place.  In any such case, the Company shall make 
appropriate provision (in form and substance reasonably satisfactory to the 
Warrant Holder) with respect to such holder's rights and interests to insure 
that the provisions of this Agreement shall thereafter be applicable to the 
Warrants (including, in the case of any such consolidation, merger or sale in 
which the successor entity or purchasing entity is other than the Company, 
any adjustment of the Exercise Price based on Section 10 hereof).  The 
Company shall not effect any such consolidation, merger or sale, unless prior 
to the consummation thereof, the successor entity (if other than the Company) 
resulting from consolidation or merger or the entity purchasing such assets 
assumes by written instrument (in form and substance reasonably satisfactory 
to the Warrant Holder), the obligation to deliver to the Warrant Holder such 
shares of stock, securities or assets as, in accordance with the foregoing 
provisions, such holder may be entitled to acquire.

         (f)  If any event occurs of the type contemplated by the provisions 
of this Section 10 but not expressly provided for by such provisions 
(including, without limitation, the granting of stock appreciation rights, 
phantom stock rights or other rights with equity features), then the 
Company's Board shall make an appropriate adjustment in the Exercise Price 
and the number of shares of Common Stock obtainable upon exercise of this 
Warrant so as to protect the rights of the Warrant Holder; provided that no 
such adjustment shall increase the Exercise Price or decrease the number of 
shares of Common Stock obtainable as otherwise determined pursuant to this 
Section 10.

         (g)  If the Company declares or pays a dividend upon the Common 
Equity payable otherwise than in cash out of earnings or earned surplus 
(determined in accordance with generally accepted accounting principles, 
consistently applied) except for a stock dividend payable in shares of Common 
Stock (a "Liquidating Dividend"), then the Company shall pay to the Warrant 
Holder at the time of


                                      9


<PAGE>

payment thereof the Liquidating Dividend which would have been paid to such 
Warrant Holder on the Common Stock had the Warrants been fully exercised 
immediately prior to the date on which a record is taken for such Liquidating 
Dividend, or, if no record is taken, the date as of which the record holders 
of Common Equity entitled to such dividends are to be determined.

               SECTION 11.  FRACTIONAL INTERESTS. 

               The Company shall not be required to issue fractional Warrant 
Shares upon the exercise of Warrants.  If more than one Warrant shall be 
presented for exercise in full at the same time by the Warrant Holder, the 
number of full Warrant Shares which shall be issuable upon the exercise 
thereof shall be computed on the basis of the aggregate number of Warrant 
Shares purchasable on exercise of the Warrants so presented.  If any fraction 
of a Warrant Share would, except for the provisions of this Section 11, be 
issuable on the exercise of any Warrants (or specified portion thereof), the 
Company shall pay an amount in cash equal to the "fair market value" 
(determined as provided in Section 5(a) above) of the Common Stock on the day 
immediately preceding the date the Warrant is presented for exercise, 
multiplied by such fraction.

               SECTION 12.  FINANCIAL STATEMENTS.

               (a)  Whether or not required by the rules and regulations of 
the Securities and Exchange Commission (the "Commission"), so long as any of 
the Warrants remain outstanding, the Company shall furnish to the Warrant 
Holder (i) all quarterly and annual financial information that would be 
required to be contained in a filing with the Commission on Forms 10-Q and 
10-K if the Company were required to file such Forms, including "Management's 
Discussion and Analysis of Financial Condition and Results of Operations" 
and, with respect to the annual information only, a report thereon by the 
Company's certified independent accountants and (ii) all current reports that 
would be required to be filed with the Commission on Form 8-K if the Company 
were required to file such reports. In addition, whether or not required by 
the rules and regulations of the Commission, the Company shall file a copy of 
all such information and reports with the Commission for public availability 
(unless the Commission will not accept such a filing).

               (b)  The Company shall, so long as any of the Warrants are 
outstanding, deliver to the Warrant Holder, forthwith upon any Executive 
Officer of the Corporation becoming aware of any default under this 
Agreement, an Officers' Certificate specifying such default and what action 
the Company is taking or proposes to take with respect thereto.

               SECTION 13.  NOTICES TO WARRANT HOLDER.  

               (a)  Upon any adjustment of the Exercise Price or exercise 
privileges pursuant to Section 10, the Company shall promptly thereafter (i) 
cause to be filed with the Company a certificate of a firm of independent 
public accountants of recognized standing, selected by the Board (who may be 
the regular auditors of the Company) and acceptable to the Warrant Holder, 
setting forth the Exercise Price after such adjustment and setting forth in 
reasonable detail the method of calculation and the facts upon which such 
calculations are based and setting forth the number of Warrant Shares (or 
portion thereof) issuable after such adjustment in the Exercise Price, which 
certificate shall be conclusive evidence of the correctness of the matters 
set forth therein, upon exercise of a Warrant and payment of the adjusted 
Exercise Price, and (ii) cause to be given to each of the registered holders 
of the Warrant Certificate(s), at his or her address appearing on the Warrant 
Register, written notice of such adjustments by first-class 


                                       10

<PAGE>

mail, postage prepaid.  Where appropriate, such notice may be given in
advance and included as a part of the notice required to be mailed under the
other provisions of this Section 13.


               (b)  In case:

                    (1)  the Company shall authorize the issuance to all 
               holders of shares of Common Stock of the Company rights to 
               subscribe for, or to purchase shares of, Common Stock or of any
               other subscription rights or warrants; or

                    (2)  the Company shall authorize the distribution to all 
               holders of shares of Common Stock of evidences of its 
               indebtedness or assets; or

                    (3)  of any consolidation or merger to which the Company is
               a party and for which approval of any shareholders of the Company
               is required, or of the conveyance or transfer of the properties 
               and assets of the Company substantially as an entirety, or of any
               reclassification or change of  Common Stock issuable upon 
               exercise of the Warrants, or a tender offer or exchange offer 
               for shares of Common Stock; or

                    (4)  of the voluntary or involuntary dissolution, 
               liquidation or winding up of the Company or a Liquidating 
               Dividend; or

                    (5)  the Company proposes to take any action which would 
               require an adjustment of the Exercise Price or the Warrant Shares
               pursuant to Section 10;

then the Company shall cause to be given to each of the registered holders of 
the Warrant Certificates at his or her address appearing on the Warrant

                                     [REVERSE]

               The Warrants evidenced by this Warrant Certificate are part of 
a duly authorized issue of Warrants expiring on the Expiration Date, 
entitling the holder on exercise to receive shares of Common Stock, $.001 par 
value, of the Company (the "Common Stock"), and are issued or to be issued 
pursuant to the Warrant Agreement, duly executed and delivered by the 
Company, which Warrant Agreement is hereby incorporated by reference in and 
made a part of this instrument and is hereby referred to for a description of 
the rights, limitation of rights, obligations, duties and immunities 
thereunder of the Company and the holders (the words "holders" or "holder" 
meaning the registered holders or registered holder) of the Warrants (the 
"Warrant Holders"). A copy of the Warrant Agreement may be obtained by the 
holder hereof upon written request to the Company.

               Warrants may be exercised at any time on or before the 
Expiration Date. The holder of Warrants evidenced by this Warrant Certificate 
may exercise them by surrendering this Warrant Certificate, with the form of 
election to purchase set forth herein properly completed and executed, 
together with payment of the Exercise Price in cash at the office of the 
Company designated for such purpose. In the alternative, each Warrant Holder 
may exercise its right, during the Exercise Period, as defined in the Warrant 
Agreement, to receive Warrant Shares on a net basis, such that, without the 
exchange of any funds, the Warrant Holder receives that number of Warrant 
Shares otherwise issuable (or payable) upon exercise of its Warrants less 
that number of Warrant Shares having an aggregate fair market value (as 
defined below) at the time of exercise equal to the aggregate Exercise Price 
that would otherwise have been paid by the Warrant Holder of the Warrant 
Shares.  For purposes of the foregoing sentence, "fair market value" of the 
Warrant Shares will be determined in the manner set forth in the Warrant 
Agreement.  In the event that upon any exercise of Warrants evidenced hereby 
the number of Warrants exercised shall be less than the total number of 
Warrants evidenced hereby, there shall be issued to the holder hereof or his 
assignee a new Warrant Certificate evidencing the number of Warrants not 
exercised. Except as provided in Section 10 of the Warrant Agreement, no 
adjustment shall be made for any dividends on any Common Stock issuable upon 
exercise of this Warrant.

               The Warrant Agreement provides that, upon the occurrence of 
certain events, the Exercise Price and the number of Warrant Shares set forth 
on the face hereof may, subject to certain conditions, be adjusted. No 
fractions of a share of Common Stock will be issued upon the exercise of any 
Warrant, but the Company will pay the cash value thereof determined as 
provided in the Warrant Agreement. 

               The holders of the Warrants are entitled to certain 
registration rights with respect to the Common Stock purchasable upon 
exercise thereof.  Said registration rights are set forth in full in a 
Registration Rights Agreement dated as of October __, 1997, between the 
Company and the Warrant Holder.  A copy of the Registration Rights may be 
obtained by the holder hereof upon written request to the Company.

               Warrant Certificates, when surrendered at the office of the 
Company by the registered holder thereof in person or by legal representative 
or attorney duly authorized in writing, may be exchanged, in the manner and 
subject to the limitations provided in the Warrant Agreement, but without 
payment of any service charge, for another Warrant Certificate or Warrant 
Certificates of like tenor evidencing in the aggregate a like number of 
Warrants.

               Upon due presentation for registration of transfer of this 
Warrant Certificate at the office of the Company, a new Warrant Certificate 
or Warrant Certificates of like tenor and evidencing in the aggregate


                                       4

<PAGE>

a like number of Warrants shall be issued to the transferee(s) in exchange 
for this Warrant Certificate, subject to the limitations provided in the 
Warrant Agreement, without charge except for any tax or other governmental 
charge imposed in connection therewith.

               The Company may deem and treat the registered holder(s) 
thereof as the absolute owner(s) of this Warrant Certificate (notwithstanding 
any notation of ownership or other writing hereon made by anyone), for the 
purpose of any exercise hereof, of any distribution to the holder(s) hereof, 
and for all other purposes, and the Company shall not be affected by any 
notice to the contrary. Neither the Warrants nor this Warrant Certificate 
entitles any holder hereof to any rights of a stockholder of the Company.

infusion is strong evidence of The Carlyle Group's and GE's support for this
management team and the long-term strategic direction InSight is pursuing.  It
places the Company in a significantly stronger financial position from which to
execute its business plan.  It also enhances InSight's ability to maximize
shareholder value."
    E. Larry Atkins, InSight's President and Chief Executive Officer added,
"This capital infusion is an enormous step forward for InSight - one that
substantially boosts our resources, lowers our cost of capital and fuels our
future growth.  We are in the midst of several growth initiatives, including
acquisitions, expansion of open MRI units and continued development of our
radiology co-sourcing product.  All these programs will be supported from a
stronger capital base as a result of this investment.  We are delighted to be
associated with organizations of Carlyle's, NationsBank's and GE's caliber.  The
conversion price of the new Preferred Stock is at a supplemental premium to the
recent trading price of our Common Stock, which we believe is a real vote of
confidence from these organizations."

NATIONSBANK CREDIT AGREEMENT

    The $125 million NationsBank financing will include a term loan designed to
refinance existing debt, a working capital facility and an acquisition facility.
The working capital and acquisition facilities will result in $75 million of new
capacity to fuel growth and acquisitions.  These senior credit facilities will
result in a two hundred basis point reduction in current interest rate costs
over the refinanced debt.  Funding is subject to the satisfaction of certain
customary conditions and is expected to occur within two weeks.

THE CONVERTIBLE SECURITIES
     As part of the transaction, GE has agreed to convert all of its existing 
non-voting Series A Preferred Stock into the new Series C Preferred Stock 
upon expiration or earlier termination of the 30-day waiting period under the 
Hart-Scott-Rodino Antitrust Improvements Act.  GE has also received 835,821 
shares of Series C Preferred Stock in exchange for the early cancellation of 
the supplemental service fee agreement, thereby eliminating InSight's annual 
expense representing a fourteen percent pretax income payment to GE.  This 
termination will result in a non-recurring expense of approximately $6.7 
million in the second quarter of fiscal 1998.  When converted, GE's holdings 
would represent 34 percent of the current fully-diluted outstanding shares, 
and has an initial conversion price of $8.38 per share of Common Stock.  GE 
has also acquired warrants to purchase 250,000 shares of InSight Common Stock 
at an initial exercise price of $10.00 per share.
    The Series B Preferred Stock purchased by Carlyle will be convertible
initially into an aggregate of 2,985,075 shares of InSight Common Stock, or 31
percent of the fully-diluted outstanding shares, at an initial conversion price
of $8.38 per share of Common Stock.  Carlyle has also acquired warrants to
purchase 250,000 shares of InSight Common Stock at an initial exercise price of
$10.00 per share.

      INSIGHT HEALTH SERVICES INCREASES CREDIT FINANCING TO $150 MILLION

         -TERMS OF ORIGINAL CREDIT FINANCING INCREASED BY $25 MILLION-


     Newport Beach, CA, December 22, 1997 -- InSight Health Services Corp. 
(NASDAQ: IHSC) today announced it had closed an additional $25 million in

N.A. The original credit financing was announced in conjunction with a $25 
million equity investment in InSight by The Carlyle Group on October 14,

its original $125 million to its current $150 million.

acquisitions, expand our open MRI program, and continue with the development 
of our radiology co-sourcing product. The $25 million increase in funding 
over the amount originally announced in October is a vote of confidence in 
InSight and its strategy. We have a robust acquisition pipeline and this 
funding will make it possible to accelerate strategic acquisitions that are 
immediately accretive to the Company."
