     In connection with a restructuring of indebtedness of the Company, pursuant

converted into Series A Convertible Preferred Stock of InSight.  The foregoing
response to this Item 4 is qualified in its entirety by reference to the Stock
Acquisition Agreement (a copy of which is attached hereto as Exhibit 3), which
is hereby incorporated herein.

     Except as described in this Item 4, GE has no current plans which relate to
or would result in any of the events described in Items (a) through (j) of the

     (a)  GE beneficially owns an aggregate of 700,000 Common Shares (all of
which are issuable upon exercise of the Warrant), representing an aggregate of
23.5% of the outstanding Common Shares (assuming exercise of the Warrant).

     (b)  The responses to Items 7-11 of the cover page of this Schedule 13D
relating to beneficial ownership of Common Shares are incorporated herein by
reference.

     (c)  Except as set forth in Item 4 hereof, neither GE nor, to the best
knowledge of GE, any person identified on Schedule I hereto has effected any
transactions with respect to Common Shares within the past 60 days.

     (d)  Not Applicable.

                              RECENT GE CONVICTIONS

1.   United States ex. rel. Taxpayers Against Fraud and Chester L. Walsh v.
     General Electric Company

     On November 15, 1990, an action under the federal False Claims Act 31
U.S.C. Sections 3729-32, was filed under seal against General Electric
Company ("GE") in the United States District Court for the Southern District
of Ohio.  The qui tam action, brought by an organization called Taxpayers
Against Fraud and an employee of GE's Aircraft Engines division ("GEAE"),
alleged that GEAE, in connection with its sales of F11O aircraft engines and
support equipment to Israel, made false statements to the Israeli Ministry of
Defense (MoD), causing MoD to submit false claims to the United States
Department of Defense under the Foreign Military Sales Program.  Senior GE
management became aware of possible misconduct in GEAE's Israeli F110
program in December 1990.  Before learning of the sealed qui tam suit, GE
immediately made a voluntary disclosure to the Departments of Defense and
Justice, promised full cooperation and restitution, and began an internal
investigation.  In August 1991, the federal court action was unsealed, and
the Department of Justice intervened and took over responsibility for the case.

    On July 22, 1992, after GE had completed its investigation and made a
complete factual disclosure to the U.S. government as part of settlement
discussions, the United States and GE executed a settlement agreement and filed
a stipulation dismissing the civil action.  Without admitting or denying the
allegations in the complaint, GE agreed to pay $59.5 million in full settlement
of the civil fraud claims.  Also on July 22, 1992, in connection with the same
matter, the United States filed a four count information charging GE with
violations of 18 U.S.C. Section 287 (submitting false claims against the United
States), 18 U.S.C. Section 1957 (engaging in monetary transactions in criminally
derived property), 15 U.S.C. Sections 78m(b)(2)(A) and 78ff(a) (inaccurate
books and records), and 18 U.S.C. Section 371 (conspiracy to defraud the United
States and to commit offenses against the United States).  The same day, GE
and the United States entered a plea agreement in which GE agreed to waive
indictment, plead guilty to the information, and pay a fine of $9.5 million.
GE was that day sentenced by the federal court in accordance with the plea
agreement.

2.   Except for the foregoing, GE has not and, to the best of GE's knowledge,
none of the directors and executive officers of GE has been, during the last
five years, convicted in a criminal proceeding (excluding traffic violations or
similar misdemeanors).

3.   GE has not and, to the best of GE's knowledge, none of the directors and
executive officers of GE has been, during the last five years, a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree, or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

2.   RESTRUCTURING OF CERTAIN OBLIGATIONS OF MAXUM

     2.1   Master Equipment Lease.  GE and Maxum agree to reorganize, combine
and consolidate the equipment leases described on Exhibit 2.1 attached hereto
(collectively, the "Equipment Leases") into a single Master Leaseline Agreement
("Master Equipment Lease") to be entered into by the parties as of the Effective
Date in the form attached hereto as Schedule 2.1.  Separate schedules shall be
attached to the Master Equipment Lease, each of which shall (1) identify and
describe the Unit to which the schedule relates, (2) indicate whether such Unit
is characterized as a Fixed Unit, a Variable Unit, a Suspended Unit or a Rental
Unit as of the Effective Date, (3) indicate whether such Unit is a Mobile/Mobile
Unit or a Fixed/Mobile Unit (if the Unit is a Variable Unit as of the Effective
Date), (4) set forth the lease term for such Unit, (5) set forth the monthly
lease payment amount if such Unit is a Fixed Unit or a Rental Unit as of the
Effective Date; (6) describe the locations where the Unit is operated, and (7)
set forth such other terms and conditions with respect to such Unit as the
parties may agree.  For purposes of this Agreement, the term "Master Equipment
Lease" shall include all schedules and addenda that may be attached to the
Master Equipment Lease by the parties from time to time.  As of the Effective
Date, the compensation mechanism and all other provisions contained in the
Master Equipment Lease and in Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7 and 2.8
below shall supersede in their entirety all of the provisions contained in the
individual Equipment Leases and all schedules and addenda thereto.  GE and Maxum
acknowledge and agree that (i) it is not their intention to terminate the
individual Equipment Leases by entering into the Master Equipment Lease, and
(ii) neither this Agreement nor the Master Equipment Lease shall constitute a
novation of any or all of the individual Equipment Leases.

     2.2   Pool of Assets.

           (A) Fixed Unit Pool.  Those Units having rolling four (4) month
average Billings equal to or above the Upper Variable Unit Threshold shall
qualify as Fixed Units.  The Fixed Unit Pool shall consist of all Units that are
characterized as Fixed Units in accordance with the terms of this Agreement.

           (B) Variable Unit Pool.  Those Units having rolling four (4) month
average Billings both (1) below the Upper Variable Unit Threshold, and (2) equal
to or above the Lower Variable Unit Threshold shall qualify as Variable Units. 
The Variable Unit Pool shall consist of all Units that are characterized as
Variable Units in accordance with the terms of this Agreement.  Each Variable
Unit shall be further characterized as either a Fixed/Mobile Unit or a
Mobile/Mobile Unit as of the Effective Date.  Such characterization shall also
be reflected on Exhibit 2.2(E) and the appropriate schedule to the Master
Equipment Lease as provided in Section 2.1.

           (C) Suspended Unit Pool.  (1) Those Units having rolling four (4)
month average Billings below the Lower Variable Unit Threshold, or (2) those
Units which become completely idle after all End-User Customer Contracts served
by that Unit have expired or otherwise have been terminated without renewal or
replacement shall qualify as Suspended Units.  The Suspended Unit Pool shall
consist of all Units that are characterized as Suspended Units in accordance
with the terms of this Agreement.

           (D) Rental Unit Pool.  Those Units that are placed back in service
from the Suspended Unit Pool pursuant to a Sublease (as defined in Section
2.3(B) below).  The Rental Unit Pool shall consist of all Units that are
characterized as Rental Units in accordance with the terms of this Agreement.

           (E) Unit Characterization.   The parties shall determine whether each
Unit will be characterized as a Fixed Unit, Variable Unit, Suspended Unit or
Rental Unit as of the Effective Date and such characterization shall be set
forth in Exhibit 2.2(E) attached hereto and reflected on the appropriate
schedule to the Master Equipment Lease, as provided in Section 2.1 above.  The
characterization of a Unit as a Fixed Unit, Variable Unit, Suspended Unit or
Rental Unit shall be effective as of the Effective Date.  A Unit may be
recharacterized at any time following the Effective Date until termination of
this Agreement in accordance with the provisions of this Section 2.  In the
event a Unit is recharacterized in accordance with this Section 2 following the
Effective Date but prior to the Closing Date, such recharacterization shall be
reflected on Exhibit 2.2(E) in addition to the addendum signed by the parties
pursuant to Section 2.3(C)(5) below.

     2.3   Changes in Unit Characterization.  

           (A) Determination of Changes in Billings.  Within the first ten (10)
Business Days of each calendar month following the Effective Date, Maxum shall
calculate the average Billings for the previous four (4) month period for each
Unit that is not in the Suspended Unit Pool or Rental Unit Pool and determine
whether any Fixed Unit's rolling four (4) month average Billings have decreased
below the Upper Variable Unit Threshold or Lower Variable Unit Threshold, or
whether any Variable Unit's rolling four (4) month average Billings have
decreased below the Lower Variable Unit Threshold.  If Maxum elects to have a
particular Unit recharacterized as a result of such decrease as described in the
preceding sentence, then Maxum shall provide written notice to GE as provided in
Section 2.3(C) below.

           (B) Rental Units.  The parties acknowledge that during the term of
this Agreement, Maxum may seek to enter into a sublease ("Sublease") with an
End-User Customer or another Person pursuant to which the End-User Customer or
other Person, rather than Maxum, will operate a particular Unit that is
characterized as a Suspended Unit pursuant to this Agreement so that such Unit
may be placed back in service.  In the event that Maxum intends to enter into a
Sublease with an End-User Customer or another Person with respect to a
particular Suspended Unit and, therefore, have such Unit recharacterized as a
Rental Unit pursuant to this Agreement, then Maxum shall provide written notice
to GE as provided in Section 2.3(C)(3) below, along with a copy of the proposed
Sublease that relates to the Suspended Unit that may be recharacterized as a
Rental Unit.  Notwithstanding any other provision contained in this Agreement to
the contrary, a Rental Unit is not subject to recharacterization as a Variable
Unit or a Suspended Unit pursuant to the terms of this Agreement as a result of
the Billings with respect to such Rental Unit.  Such Unit may only be
recharacterized as a Suspended Unit as a result of the expiration or termination
without renewal or replacement of the Sublease with respect to such Rental Unit
as provided in Section 2.3(C)(3) below, the terms of which are approved by GE in
accordance with Section 2.3(C)(3) below.  Following such recharacterization as a
Suspended Unit, such Unit may be placed back in service as a Fixed Unit,
Variable Unit or as a Rental Unit in accordance with the terms of this
Agreement.

           (C) Written Notice From Maxum Regarding Unit Recharacterization.

               (1)  Maxum shall provide a written notice to GE notifying GE that
a particular Fixed Unit qualifies for recharacterization as a Variable Unit or
as a Suspended Unit or that a particular Variable Unit qualifies for
recharacterization as a Suspended Unit.  The written notice shall document, in a
manner reasonably acceptable to GE, the information from which Maxum has
determined that a particular Unit qualifies for recharacterization as provided
above.  Appropriate documentation may include, without limitation, a chronology
of the information provided by Maxum to GE pursuant to Section 2.4 below
detailing the previous four (4) months of Billings for a particular Unit, copies
of all End-User Customer Contracts that have expired or otherwise have been
terminated without renewal or replacement with respect to a particular Unit in
the event that Unit qualifies for the Suspended Unit Pool pursuant to
Section 2.2(C)(2) above (including copies of any termination notices with
respect to such contract(s)), and such other relevant information that would
enable GE to confirm Maxum's determination.  GE shall have the right to
challenge Maxum's determination within ten (10) Business Days following receipt
of such notice; provided, however, that GE may reasonably request additional
information and shall have an additional period of ten (10) Business Days
following GE's receipt of all such information to challenge Maxum's
determination.  

               (2)  Maxum shall provide notice to GE in the event that Maxum
desires for a particular Suspended Unit to be placed back in service as a Fixed
Unit or as a Variable Unit.  Recharacterization of such Suspended Unit as a
Fixed Unit rather than as a Variable Unit shall be permitted by GE only if (i)
such Suspended Unit has not been characterized at any time by the parties
pursuant to this Agreement as a Variable Unit, (ii) Billings from the Suspended
Unit are anticipated to exceed the Fixed Unit Payment with respect to such Unit
(if the Unit was characterized as a Fixed Unit as of the Effective Date), as
determined by GE in its sole discretion, and (iii) Billings from the Suspended
Unit are anticipated to exceed the Pre-Restructuring Lease Payment with respect
to such Unit (if the Unit was characterized as a Suspended Unit as of the
Effective Date), as determined by GE in its sole discretion.  Maxum shall
provide GE with appropriate information and documentation as is necessary, in
GE's reasonable discretion, to make such determination.  

               (3)  Maxum shall provide notice to GE in the event that Maxum
desires for a particular Suspended Unit to be recharacterized and placed back in
service as a Rental Unit.  Recharacterization of such Suspended Unit as a Rental
Unit shall be permitted by GE if (i) the terms of the Sublease to be entered
into by Maxum with respect to such Unit are reasonably acceptable to GE, (ii)
Maxum and GE negotiate a fixed monthly lease payment to be paid by Maxum with
respect to such Unit for so long as such Unit is characterized as a Rental Unit,
and (iii) Maxum and GE negotiate the term that the Unit will be characterized as
a Rental Unit.

               (4)  Maxum shall provide notice to GE in the event that Maxum
desires to have a Rental Unit recharacterized as a Suspended Unit.  Maxum shall
further provide GE with a copy of the Sublease that has expired or otherwise
been terminated without renewal or replacement (including copies of any
termination notices with respect to such contract).  Recharacterization of a
Rental Unit as a Suspended Unit shall be permitted by GE if the Sublease with
respect to such Unit expires or otherwise terminates without renewal or
replacement.

               (5)  Any challenge by GE to Maxum's determination that a Unit
qualifies for recharacterization must be in writing and received by MHC within
the time period herein stated; otherwise such right to challenge shall be
automatically terminated.  Any recharacterization of a Unit pursuant to this
Agreement shall be reflected on an Addendum to the applicable schedule to the
Master Equipment Lease that relates to such Unit, which Addendum shall be signed
by the parties and set forth the information described in Section 2.1 above as
of the effective date of the Addendum.  Further, if a Unit is recharacterized as
a Variable Unit, the Addendum shall further describe whether the Unit is a
Fixed/Mobile Unit or a Mobile/Mobile Unit.  

           (D) Effective Date of Unit Recharacterization.  For purposes of this
Agreement and the Master Equipment Lease, (i) if a Fixed Unit or a Variable Unit
is recharacterized as a Suspended Unit, such recharacterization shall be
effective on the date such Unit qualifies for recharacterization, (ii) if a
Fixed Unit is recharacterized as a Variable Unit, such recharacterization shall
be effective on the first day of the month in which the Unit qualifies for
recharacterization, (iii) if a Suspended Unit is recharacterized as a Fixed
Unit, Variable Unit or Rental Unit, such recharacterization shall be effective
on the date such Suspended Unit is placed back in service or the effective date
of the End-User Customer Contract or Sublease, as applicable, with respect
thereto, whichever occurs first, and (iv) if a Rental Unit is recharacterized as
a Suspended Unit, such recharacterization shall be effective on the date such
Unit qualifies for recharacterization (which is the date the Sublease with
respect to that Unit expires or otherwise terminates without renewal or
replacement), in each case, however, subject to GE's right to challenge such
recharacterization in accordance with Section 2.3(C) of this Agreement.  

     2.4   Monthly Reports.  On or before the tenth (10th) Business Day of each
calendar month during the term of this Agreement, Maxum shall furnish GE with a
detailed statement setting forth (1) the total Billings from each End-User
Customer Contract attributable to the operation or use of the Unit covered
thereby during the preceding calendar month, (2) commencing in November of 1993,
an accounts receivable aging report for each End User Customer Contract as of
the end of the preceding calendar month relating to the use or operation of the
Unit covered thereby, and (3) a report identifying charges that have been
written off with respect to (i) each Unit and (ii) each End-User Customer
Contract, and such other information as GE may reasonably request from time to
time.  

     2.5   Lease Payments; Lease Terms.  

           (A) Fixed Unit Lease Payments.  The lease payment with respect to
each Fixed Unit in the Fixed Unit Pool as of the Effective Date shall be the
restructured lease payment set forth in Exhibit 2.5(A) ("Fixed Unit Payment"),
and such additional amounts which may be payable by Maxum as a result of a
change in Maxum's routes to End User Customers, as provided in Section 2.5(B)(5)
below.  The lease payment with respect to each Suspended Unit that is
recharacterized as a Fixed Unit during the term of this Agreement shall be (i)
the Fixed Unit Payment, if the Unit was characterized as a Fixed Unit as of the
Effective Date, or (ii) the Pre-Restructuring Lease Payment, if the Unit was
characterized as a Suspended Unit as of the Effective Date, and such additional
amounts which may be payable by Maxum as a result of a change in Maxum's routes
to End-User Customers, as provided in Section 2.5(B)(5) below.  The Fixed Unit
Payment amount with respect to each Fixed Unit shall be set forth in the
appropriate schedule to the Master Equipment Lease, as provided in Section 2.1
above.  The Fixed Unit Payment or Pre-Restructuring Lease Payment, as
applicable, shall be due and payable by Maxum to GE monthly in advance on or
before the first (1st) day of each month during the respective remaining lease
term of each Fixed Unit, commencing on the Effective Date or the effective date
of recharacterization, as applicable.

           (B) Variable Unit Lease Payments; Term.  

               (1)  Payment Amount.  The Variable Unit Payment for each Variable
Unit in the Variable Unit Pool shall be the sum of (1) the Minimum Lease
Payment, and (2) an amount equal to forty percent (40%) of the Variable Unit's
monthly Billings for the previous calendar month that are in excess of the sum
of (a) the applicable Expense Ante for that Variable Unit, and (b) the Minimum
Lease Payment.  Notwithstanding the foregoing, if a Unit is characterized as a
Fixed Unit but qualifies in a particular month for characterization as a
Variable Unit or a Suspended Unit, Maxum shall have the option in that month to
make lease payments in an amount equal to the applicable Fixed Unit Payment for
such Unit (if such Unit was characterized as a Fixed Unit as of the Effective
Date), or the Pre-Restructuring Lease Payment (if such Unit was characterized as
a Suspended Unit as of the Effective Date, as applicable), in which event that
Unit shall continue to be characterized and treated under this Agreement and in
the Master Equipment Lease as a Fixed Unit.  However, except as provided in
Section 2.6 hereof, once Maxum has provided written notice to GE notifying GE
that such Fixed Unit qualifies for recharacterization as a Variable Unit or a
Suspended Unit and such Unit is recharacterized as a Variable Unit or a
Suspended Unit in accordance with this Agreement, Maxum shall no longer have the
option described immediately above to make the Fixed Unit Payment or Pre-
Restructuring Lease Payment, as applicable, with respect to such Unit; provided,
however, in the event Maxum notifies GE that a Fixed Unit qualifies as a
Suspended Unit and such Unit is characterized as a Suspended Unit, Maxum shall
have the right to have such Unit recharacterized as a Fixed Unit in accordance
with Section 2.3(C)(2).  

               (2)  Expense Antes.  

                    (a)  Two (2) expense antes ("Expense Antes") have been
established by the parties with respect to the Variable Units as provided below
which shall be applicable depending upon whether the Variable Unit is
characterized as a Fixed/Mobile Unit or a Mobile/Mobile Unit.  The Fixed/Mobile
Unit Expense Ante shall be applicable to each Fixed/Mobile Unit, and the
Mobile/Mobile Unit Expense Ante shall be applicable to each Mobile/Mobile Unit. 
Except as otherwise noted immediately below, each Expense Ante shall include (i)
personnel compensation and benefits, fleet expenses (Mobile/Mobile Unit Expense
Ante only), operating expenses, insurance and property taxes (collectively,
"Variable Unit Expenses"), and (ii) the cost to provide maintenance and cryogens
to each Variable Unit on a monthly basis, which for purposes of this Agreement
shall be equal to the amount that GE would charge Maxum on a monthly basis to
provide maintenance and cryogens with respect to magnetic resonance imaging
equipment similar to the Variable Units pursuant to a National Account Service
Contract (collectively, "Maintenance and Cryogens Costs").  

                    (b)  As of the Effective Date, the Fixed/Mobile Unit Expense
Ante shall be an amount equal to Twenty-Eight Thousand Dollars ($28,000).  Of
such amount, Eighteen Thousand Dollars ($18,000) is attributable to Variable
Unit Expenses and Ten Thousand Dollars ($10,000) is attributable to Maintenance
and Cryogen Costs.  

                    (c)  As of the Effective Date, the Mobile/Mobile Unit
Expense Ante shall be an amount equal to Thirty-Two Thousand Dollars ($32,000). 
Of such amount, Twenty-Two Thousand Dollars ($22,000) is attributable to
Variable Unit Expenses and Ten Thousand Dollars ($10,000) is attributable to
Maintenance and Cryogen Costs.  

                    (d)  The Fixed/Mobile Unit Expense Ante and the
Mobile/Mobile Unit Expense Ante shall each be adjusted on an annual basis on
June 1 of each year commencing on June 1, 1994, as follows:  (x) the Variable
Unit Expense component of each Expense Ante shall be increased by the percentage
increase in the CPI; and (y) the Maintenance and Cryogens Cost component of each
Expense Ante shall be increased by the increased monthly costs, if any, that GE
would charge Maxum to provide maintenance and cryogens to magnetic resonance
imaging equipment similar to the Variable Units during that year pursuant to a
National Accounts Service Contract.

               (3)  Time of Variable Unit Payments.  The Minimum Lease Payment
portion of the Variable Unit Payment shall be due and payable by Maxum to GE in
advance on or before the first (1st) day of each month during the respective
lease term for each Variable Unit, commencing on the Effective Date.  The
remaining portion of the Variable Unit Payment shall be due and payable by Maxum
to GE in arrears on or before the tenth (10) Business Day of each month during
the respective lease term for each Variable Unit, commencing with the month
immediately following the Effective Date and continuing each month thereafter
until on or before the tenth (10th) Business Day of the month immediately
following the expiration or the earlier termination of the respective lease term
for each Variable Unit.  
               (4)  Extension of Variable Unit Lease Terms.  The lease term
which is set forth in the applicable Equipment Lease for each Unit that
qualifies and is characterized as a Variable Unit as of the Effective Date shall
be extended for an additional five (5) month period from the end of such lease
term.  Such extension shall be reflected in the lease term set forth in
appropriate schedule to the Master Equipment Lease.  The lease term of each Unit
that qualifies and is recharacterized as a Variable Unit during the Term of this
Agreement shall be extended for an additional five (5) month period from the end
of the lease term for each such Unit which is set forth in the applicable
schedule to the Master Equipment Lease.  The appropriate schedule to the Master
Equipment lease shall be amended by the parties or an Addendum to such schedule
shall be signed by the parties to reflect such extension.

               (5)  Change in End-User Customer Routes.  If one (1) or more End-
User Customers which were being served by a Variable Unit are thereafter served
by a Fixed Unit or by a Non-GE Unit (as defined below in Section 2.5(C)(2)) as a
result of a change by Maxum in the route serving the End-User Customer, or
otherwise, then GE shall be paid, in addition to the Fixed Unit Payment with
respect to that Fixed Unit (if applicable), an amount equal to forty percent
(40%) of the monthly Billings generated from those End-User Customers that were
being served by a Variable Unit and are thereafter served by the Fixed Unit or a
Non-GE Unit (as defined below), which amount shall be payable by Maxum to GE
until such time as either (i) the Fixed Unit qualifies and is recharacterized as
a Variable Unit, (ii) the End-User Customer Contract with respect to the End-
User Customer that was being served by the Variable Unit, and is now being
served by a Fixed Unit or a Non-GE Unit, expires or otherwise terminates without
renewal or replacement, or (iii) the End-User Customer begins being served by a
Variable Unit.  Such payments shall be due and payable monthly in arrears on or
before the tenth (10th) Business Day of each month for so long as such payments
are required to be made as provided above.  Notwithstanding the foregoing, such
additional payment shall not be required in the event GE's written consent to
the change in the route is obtained by Maxum, which consent may be withheld in
GE's sole discretion.  

           (C) Suspension of Lease Payments on Suspended Units; Term; Expenses. 


               (1)  Lease Payment Suspension.  With respect to each Unit that
qualifies as a Suspended Unit, Maxum shall have the option to either
(a) continue operating the Unit on its current route and make lease payments
with respect to that Unit in an amount equal to the applicable Fixed Unit
Payment, Pre-Restructuring Lease Payment or Variable Unit Payment for that Unit,
in which event that Unit shall be characterized and treated under this Agreement
and in the Master Equipment Lease as a Fixed Unit or a Variable Unit, as
applicable or (b) suspend the lease payment applicable to that Unit and take the
Unit out of service pursuant to Section 2.5(C)(2) below, in which event that
Unit shall be recharacterized and treated under this Agreement and the Master
Equipment Lease as a Suspended Unit following the delivery of the appropriate
notices as provided in Section 2.3(C) above.

               (2)  Suspended Units Taken Out of Service.  With respect to any
Suspended Unit that is taken out of service by Maxum, Maxum may, in its sole
discretion, consolidate those 
End-User Customers that were being served by a Suspended Unit with End-User
Customers that are being served by either an existing Fixed Unit, an existing
Variable Unit or an MRI unit that is obtained in any manner by Maxum from an
entity other than GE ("Non-GE Unit"), or consolidate the End-User Customers that
were being served by a Suspended Unit into one (1) or more new routes that would
be served by one (1) or more of the Suspended Units (which Suspended Units shall
be characterized as Variable Units for purposes of this Agreement); provided,
however, that the Billings from the consolidation of the End-User Customers into
one (1) or more new routes must be anticipated to exceed the Lower Variable Unit
Threshold as determined by GE in its sole discretion.  Maxum shall provide GE
with appropriate information and documentation as is necessary, in GE's
reasonable discretion, to make such determination.  In addition, if one (1) or
more End-User Customers which were being served by a Suspended Unit are
thereafter served by a Fixed Unit or by a Non-GE Unit, GE shall be paid, in
addition to the Fixed Unit Payment applicable to that Fixed Unit (if
applicable), an amount equal to forty percent (40%) of the monthly Billings
generated from those End-User Customers that were being served by a Suspended
Unit and are thereafter served by the Fixed Unit or a Non-GE Unit, which amount
shall be payable by Maxum to GE until such time as either (i) the Fixed Unit
qualifies and is recharacterized as a Variable Unit, (ii) the End-User Customer
Contract with respect to the End-User Customer that was being served by a
Suspended Unit, and is now being served by a Fixed Unit or a Non-GE Unit,
expires or otherwise terminates without renewal or replacement, (iii) the End-
User Customer that was being served by a Non-GE Unit begins being served by a
Variable Unit, or (iv) the Suspended Unit is placed back in service and the
rolling four (4) month average Billings with respect to such Unit exceed Fifty
Thousand Dollars ($50,000).  Such payments shall be due and payable monthly in
arrears on or before the tenth (10th) Business Day of each month for so long as
such payments are required to be made as provided above.  MHC and its First-Tier
Subsidiaries shall jointly and severally indemnify and hold GE harmless from and
against any and all claims, actions, costs and expenses (including without
limitation reasonable attorneys' fees and court costs) that GE may incur or be
subject to as a result of any action or claim initiated by an End-User Customer
or any other person or entity arising out of, in connection with, or as a result
of (1) a Suspended Unit being taken out of service, or (2) any breach of or
default under any End-User Customer Contract. 

               (3)  Extension of Suspended Unit Lease Term.  The respective
lease terms of each Suspended Unit set forth in the applicable schedule to the
Master Lease Agreement shall be extended at the end of such term by the same
number of months such Suspended Unit remains in the Suspended Unit Pool.

               (4)  Maintenance and Cryogen Costs on Suspended Units.  Maxum
agrees to continue to pay all maintenance costs and expenses necessary to
maintain all Suspended Units in good working order and condition while such
Suspended Units are in the Suspended Unit Pool; provided, however, that
commencing the first full calendar month following the Closing Date and
continuing whenever there are any Units in the Suspended Unit Pool, GE agrees
either to (1) supply at GE's sole cost all cryogens for the Suspended Units, or
(2) reimburse Maxum for its actual costs to purchase such cryogens up to a
maximum of One Thousand Five Hundred Dollars ($1,500) per Suspended Unit per
month, at GE's sole option.

           (D) Rental Unit Lease Payments; Term.  

               (1)  Payment Amount.  The lease payment with respect to each
Rental Unit shall be a fixed monthly amount that is negotiated by the parties
prior to the recharacterization of a Suspended Unit as a Rental Unit ("Rental
Unit Payment"), as provided above in Section 2.3(C)(3).  The Rental Unit Payment
amount shall be set forth in an Addendum to be attached to the Master Equipment
Lease as provided above in Section 2.3(C)(5).  The Rental Unit Payment shall be
due and payable by Maxum to GE monthly in advance on or before the first (1st)
day of each month that the Unit is characterized as a Rental Unit, commencing on
the first (1st) day of the first (1st) full calendar month following the
effective date of recharacterization of a Suspended Unit as a Rental Unit. 
Notwithstanding the foregoing, any partial month that a Unit is characterized as
a Rental Unit shall be prorated accordingly, including the month in which the
Unit is recharacterized as a Rental Unit, if such Unit is recharacterized on any
day other than the first (1st) day of the month.

               (2)  Lease Term.  The lease term of a Rental Unit shall be
negotiated by the parties and set forth on an Addendum to the Master Equipment
Lease that reflects the recharacterization of the Unit as a Rental Unit.  As
noted above in Section 2.3(C)(4), a Rental Unit may be recharacterized as a
Suspended Unit following the expiration or earlier termination of the Sublease
pertaining to the Unit.  The remaining lease term of such Suspended Unit
following recharacterization shall be equal to the remaining lease term of such
Suspended Unit prior to recharacterization as a Rental Unit, as extended
pursuant to Section 2.5(C)(3) above, less the period of time such Unit was
characterized as a Rental Unit pursuant to this Agreement.

           (E) Lease Payments Following Unit Recharacterization.  If a Unit is
recharacterized from a Fixed Unit to a Variable Unit pursuant to Section 2.3(C)
above, the maximum amount Maxum shall owe GE with respect to such Unit during
the month that the Fixed Unit qualifies for recharacterization shall be the
Variable Unit Payment amount that is payable with respect to such Unit during
such month.  If a Unit is recharacterized as a Suspended Unit pursuant to
Section 2.3(C) above, the lease payments with respect to such Suspended Unit
shall be suspended commencing on the date that the Unit qualifies for
recharacterization as a Suspended Unit, subject to GE's right to challenge said
recharacterization pursuant to Section 2.3(C) above.  In the event Maxum makes a
Fixed Lease Payment, a Pre-Restructuring Lease Payment, a Minimum Lease Payment
or a Rental Unit Payment with respect to a Unit to GE, and such payment is not
required to be made pursuant to this Agreement as a result of recharacterization
of that Unit, GE shall credit that lease payment amount or an appropriate
portion of any such lease payment against the payments to be made by Maxum to GE
in the following month.

           (F) Aggregate Interim Lease Payments.  Notwithstanding 
any other terms and conditions contained in this Section 2.5 or in Section 2.7
to the contrary, the following terms shall be applicable with respect to lease
payments payable to GE during the six (6) month period from October 1, 1993
through March 31, 1994 (the "Applicable Time Period"):

               (1)  Maxum shall make aggregate monthly lease payments to GE for
all Units leased by GE to Maxum pursuant to the Master Equipment Lease in an
amount equal to Five Hundred Thousand Dollars ($500,000), which amount shall be
due and payable on the first (1st) day of each calendar month during the
Applicable Time Period, commencing October 1, 1993.

               (2)  In the event that the aggregate monthly lease payments
otherwise payable by Maxum to GE pursuant to Sections 2.5(A)-(C) above and
Section 2.7 below for all Units during the Applicable Time Period exceed Five
Hundred Thousand Dollars ($500,000), payment of the amount that exceeds Five
Hundred Thousand Dollars ($500,000) ("Monthly Deferral Amount") shall be
deferred each month on the terms set forth in the "Deferral Note" described
below.  The Monthly Deferral Amount which may accrue each month during the
Applicable Time Period shall be added as principal to the Deferral Note
effective the first day of the month following the month when such Monthly
Deferral Amount accrued pursuant to Section 2.5(A)-(C) above or Section 2.7
below, commencing November 1, 1993.  The principal amount outstanding from time
to time under the Deferral Note (as defined below) shall bear interest at a rate
equal to eight and one-half percent (8.5%) per annum from November 1, 1993, or
the maximum rate permitted by law, whichever is less, until paid and shall be
payable over a sixty (60) month period commencing on November 1, 1993, as
provided below.

                    The parties acknowledge that Maxum routinely prepares an
internal financial report as of the end of each month that is entitled "13-Week
Cash Forecast."  Maxum shall continue to prepare such a report as of the end of
each calendar month during the Applicable Time Period in the same manner as such
reports were prepared prior to the Effective Date.  A copy of such report shall
be delivered by Maxum to GE on or before the tenth (10th) Business Day following
the end of each calendar month during the Applicable Time Period and on or
before the tenth (10th) Business Day of the calendar month following the last
month in the Applicable Time Period.

                    Maxum shall pay to GE, in arrears, on or before the tenth
(10th) Business Day following the end of each calendar month during the
Applicable Time Period and on or before the tenth (10th) Business Day of the
calendar month following the last month in the Applicable Time Period, such
portion or all of the then outstanding principal and accrued interest, if any,
under the Deferral Note, but only to the extent that Maxum's actual "Cash and
Cash Equivalents" as of the end of the immediately preceding calendar month as
reflected in the 13-Week Cash Forecast exceeds Two Million Four Hundred Thousand
Dollars ($2,400,000) ("Cash Flow Excess").  Accordingly, during the six (6)
month period from November 1, 1993 through April 30, 1994, monthly payments of
principal and interest under the Deferral Note shall be made in accordance with
the preceding sentence.  All remaining outstanding principal together with
unpaid accrued interest thereon shall be due and payable in equal monthly
installments, amortized over the remaining fifty-four (54) months of the
Deferral Note term, commencing May, 1994, all as set forth in a promissory note
("Deferral Note") which shall be executed and delivered by Maxum to GE on
Closing Date in the form attached hereto as Schedule 2.5(F).

                    Maxum shall deliver to GE on or before the tenth (10th)
Business Day following the end of each month during the Applicable Time Period,
such financial or other information reasonably requested by GE to confirm
Maxum's determination of its 13-Week Cash Forecast.  Further, GE shall have the
right to directly or through an agent, examine, audit, inspect and copy the
books, records and files kept and maintained by Maxum as well as any underlying
documentation reasonably necessary for GE to confirm the accuracy of Maxum's 13-
Week Cash Forecast in a particular month, in accordance with Section 5.1(E)
below.

                    In the event that any such audit or examination discloses
any discrepancies as reasonably determined by GE, the parties shall meet within
five (5) days to attempt to resolve such discrepancies.  Notwithstanding any
provision to the contrary contained in this Agreement, in the event that any
discrepancy cannot be resolved by the parties within twenty (20) days
thereafter, a determination of the accuracy of such 13-Week Forecast shall be
made by an independent certified public accountant selected by GE and acceptable
to Maxum in its reasonable discretion ("GE's Accountant"); provided, however,
Maxum reserves the right to protest findings made by GE's Accountant by
providing written notice to GE within ten (10) Business Days following GE's
delivery of notice to MHC regarding the results of the audit performed by GE's
Accountant and thereafter obtaining, at Maxum's cost, an audit of the 13-Week
Forecast from an independent certified public accountant selected by Maxum and
acceptable to GE in its reasonable discretion ("Maxum's Accountant").  In the
event that Maxum's Accountant determines, within thirty (30) days after delivery
of the written protest to GE, that (i) there has been no underpayment to GE
pursuant to the Deferral Note or (ii) there has been an underpayment under the
Deferral Note of Fifteen Thousand Dollars ($15,000) or less, and GE disputes
such results, then GE's Accountant and Maxum's Accountant shall select a third
accountant ("Third Accountant") (or if they cannot agree, then a Third
Accountant shall be selected by the parties, and if the parties cannot agree,
then a Third Accountant shall be selected by an arbitrator that is selected by
the Commercial Panel of the American Arbitration Association) to audit such 13-
Week Forecast, at Maxum's expense, and the findings of such accountant shall be
binding on the parties.  If the findings of GE's Accountant are not challenged
by Maxum within the time period specified above, then the findings of such
accountant shall be binding on the parties.  

                    The fees and expenses of GE's Accountant shall be borne by
GE, unless as a result of any such audit, it is determined that there has been
an underpayment by Maxum pursuant to the Deferral Note in excess of Fifteen
Thousand Dollars ($15,000) in any month during the Applicable Time Period, in
which event the fees and expenses of the accounting firm shall be borne by
Maxum.  Notwithstanding the foregoing, the fees and expenses incurred with
respect to the audit performed by the Third Accountant shall be borne by GE if
it determined by such Third Accountant that there has been an underpayment by
Maxum under the Deferral Note of Fifteen Thousand Dollars ($15,000) or less.  If
it is determined as a result of the audit that is binding on the parties as
provided above that there has been any underpayment to GE, then such
underpayment shall be immediately due and payable by Maxum to GE.  

                    GE waives all penalties and events of default arising during
the Applicable Time Period pursuant to this Agreement and the Master Equipment
Lease as a result of the nonpayment by Maxum of the Monthly Deferral Amount,
however, GE does not waive any defaults under the Deferral Note pursuant to this
Section 2.5(F).  The parties acknowledge that the Deferral Note to be delivered
by Maxum to GE on the Closing Date will not establish a new debt from Maxum to
GE but is intended to evidence GE's deferral of Maxum's obligation to pay those
lease payments constituting the Monthly Deferral Amounts in accordance with the
terms hereof and the Master Equipment Lease and to set forth the terms upon
which such Monthly Deferral Amounts shall be paid to GE.

           (G) Joint Sales Calls.  Maxum agrees to make joint sales calls with
GE to attempt to place Suspended Units with an End-User Customer pursuant to a
long term commitment that is acceptable to GE in GE's sole discretion.

           (H) Acquisition of Additional MRI Equipment.  So long as any Units
remain in the Suspended Unit Pool, neither MHC nor any of the First-Tier
Subsidiaries shall purchase, lease or otherwise acquire any new or used MRI
equipment from any person or entity until such time as each Suspended Unit
either:  (1) qualifies or is recharacterized as a Fixed Unit, Variable Unit or
Rental Unit; (2) receives a System Upgrade pursuant to Section 2.6(A) below;
(3) is placed by Maxum with an End-User Customer pursuant to a long term
commitment acceptable to GE in its reasonable discretion; or (4) is placed by GE
with any other person or entity on terms acceptable to GE in its reasonable
discretion.  Notwithstanding anything in this Agreement to the contrary, in the
event a Suspended Unit is going to be placed with an End-User Customer or with
any other person or entity pursuant to Sections 2.5(H)(3) or (4) immediately
above, GE shall have the option to have Maxum either (a) place the specific
Suspended Unit with the End-User Customer or other person or entity, or
(b) require Maxum to substitute another like Unit leased by GE to Maxum for that
Suspended Unit which would result in the placement of the substituted Unit with
the End-User Customer or other person or entity.  Upon placement of a Unit by GE
pursuant to a contract arrangement between GE and an End-User Customer that
previously contracted with Maxum, or another person or entity, Maxum's
obligations to GE with respect to that Unit (whether under this Agreement, the
Master Equipment Lease or otherwise) shall automatically terminate, except for
such obligations that accrued but remain unperformed as of the date of such
termination.

     2.6   Unit Upgrades.

           (A) System Upgrades.  Maxum may request and obtain a System Upgrade
on any Unit ("Upgraded Unit"), provided that GE determines that (1) Maxum has
entered into one (1) or more long term End-User Customer Contracts with respect
to the Upgraded Unit, and (2) GE, in its reasonable discretion, determines in
writing that the Anchor End-User Customer Contract specified in Maxum's request
and additional End-User Customer Contract(s), if any, will enable Maxum to make
the Pre-Restructuring Lease Payment applicable to the Unit that was replaced
("Replaced Unit") by the Upgraded Unit for the entire lease term of the Upgraded
Unit.  

               Maxum shall return the Replaced Unit to GE at Maxum's sole cost
and expense within ten (10) days of the date the Upgraded Unit is received by
Maxum from GE.  Further, the schedule to the Master Equipment Lease relating to
the Replaced Unit shall be terminated effective as of the date the Replaced Unit
is returned to GE ("Lease Termination"), whereupon all of Maxum's obligations
(except those obligations that accrued but remain unperformed as of the
termination date) with respect to the Replaced Unit (whether under this
Agreement, the Master Equipment Lease or otherwise) shall automatically
terminate.  A new schedule shall be simultaneously executed by the parties and
attached to the Master Equipment Lease that (1) describes the Upgraded Unit, (2)
sets forth the monthly lease payment amount for such Upgraded Unit, which shall
not be less than the Pre-Restructuring Lease Payment applicable to the Replaced
Unit, (3) sets forth the lease term of the Upgraded Unit, as provided below, (4)
describes the location where the Unit is operated, and (5) indicates which End-
User Customer Contract applicable to the Upgraded Unit is the Anchor End-User
Customer Contract.  The Upgraded Unit shall be considered a Unit for purposes of
this Agreement.  The lease term of the Upgraded Unit shall be equal to (i) the
remaining lease term for the Replaced Unit at the time of the Lease Termination,
plus (ii) an additional period of months as determined by GE so that the
additional cost to Maxum to obtain the System Upgrade will not increase the Pre-
Restructuring Lease Payment applicable to the Replaced Unit.  

               Notwithstanding any other provision in this Agreement to the
contrary, the Upgraded Unit shall be characterized as a Fixed Unit and shall
remain in the Fixed Unit Pool until such time as (1) the term of the Anchor End-
User Customer Contract applicable to the Upgraded Unit expires in accordance
with its terms (excluding an early termination by the parties or other early
termination in accordance with the Anchor End-User Customer Contract for any
reason other than as a result of (i) the institution of liquidation proceedings
by or against the End-User Customer pursuant to applicable bankruptcy laws,
which proceedings are not dismissed within thirty (30) days thereafter or
(ii) the End-User Customer otherwise ceasing to operate without a third party
assuming the operations of the End-User Customer) without renewal or
replacement, or (2) the last End-User Customer Contract applicable to the
Upgraded Unit expires or is otherwise terminated without renewal or replacement,
whichever occurs sooner; whereupon such Upgraded Unit will be subject to
recharacterization in accordance with the terms of this Agreement.  Maxum shall
not amend the Anchor End-User Customer Contract to reduce the length of the term
of such contract without the prior written consent of GE, which consent may be
withheld in GE's sole discretion.  

               Notwithstanding anything contained in this Section 2.6(A) to the
contrary, the first five (5) System Upgrades requested and obtained by Maxum
shall be provided with respect to the Units identified on Exhibit 2.6(A)
attached hereto for which Maxum has "credited two-step upgrades" as more
particularly described on Exhibit 2.6(A).

           (B) System Option Upgrades.  Maxum may request and obtain a System
Option Upgrade on any Unit in the Fixed Unit Pool or the Variable Unit Pool.  A
description of each System Option Upgrade and the lease terms for such upgrade
shall be referenced on a new schedule that shall be executed by the parties and
attached to the Master Equipment Lease.  Such schedule shall have a term that is
coterminous with the lease term for the Unit that receives the System Option
Upgrade.  The monthly payment amount for such System Option Upgrade shall be a
monthly fixed amount which is equal to the cost of the System Option Upgrade
amortized over the remaining lease term of the Unit that receives the System
Option Upgrade.  Notwithstanding any other provision in this Agreement to the
contrary, all lease payments with respect to System Option Upgrades to a
particular Unit shall be payable by Maxum notwithstanding whether the Unit that
receives the System Option Upgrade is a Variable Unit or becomes a Suspended
Unit.

     2.7   MRI for Doctors Hospital.  Notwithstanding any other provision in
this Section 2 to the contrary (except for Section 2.5(F)), the letter agreement
dated October 22, 1992 between GE and MHSC, a copy of which is attached hereto
as Exhibit 2.7, which letter agreement relates to GE's lease of the Unit
described therein to MHSC pursuant to that certain Leaseline Agreement (GE
Contract No. 8506128-001), dated October 22, 1992, shall remain in effect.  If
such Unit is returned by MHSC to GE in accordance with the terms of the letter
agreement, Maxum shall simultaneously execute and deliver a promissory note
("Second Deferral Note") to GE in the applicable aggregate principal amount set
forth in the amortization schedule attached hereto as Exhibit 2.7, based on the
return date ("Return Date"), which amount remaining from time to time unpaid
shall bear interest at a rate equal to nine and three fourths percent (9.75%)
per annum, or the maximum rate permitted by law, whichever is less, and shall be
payable in equal monthly installments of principal and interest over a sixty
(60) month period.  If the Unit is not returned on the first day of the month,
the Return Date for purposes of calculating the principal amount owning under
the Second Deferral Note shall be the first day of the month in which the Unit
is returned.  The Second Deferral Note shall be in the form attached hereto as
Schedule 2.7.  The parties acknowledge that the Second Deferral Note above does
not establish a new debt from Maxum to GE but is intended to evidence Maxum's
obligation to pay the remaining debt to GE with respect to the MRI unit
described in the letter agreement and to set forth the terms upon which such
payments shall be made to GE.  

     2.8   Skip Lease Payments.  GE hereby defers Maxum's obligation to make (1)
the lease payments that are due and owing for the months of March, 1993 through
May, 1993 under the Equipment Leases with respect to (a) those Units that are in
the Suspended Unit Pool as of the Effective Date, (b) those Units that are
anticipated to become Suspended Units as identified on Exhibit 2.8 attached
hereto, which lease payments are in an aggregate amount equal to Nine Hundred
Seventy-Six Thousand Six Hundred Eighty-Four Dollars and Twenty-Five Cents
($976,684.25), and (2) the lease payments that are due and owing for the month
of June, 1993 with respect to all Units leased by GE to Maxum as of the
Effective Date, which lease payments are in an aggregate amount equal to Eight
Hundred Fifty Thousand Twelve Dollars and Two Cents ($850,012.02), for a total
of One Million Eight Hundred Twenty-Six Thousand Six Hundred Ninety-Six Dollars
and Twenty-Seven Cents ($1,826,696.27) (collectively, the "Skip Lease
Payments").  GE waives all penalties and events of default arising prior to the
Effective Date pursuant to the Equipment Leases as a result of the nonpayment by
Maxum of the Skip Lease Payments but does not waive any defaults under the Third
Deferral Note pursuant to this Section 2.8.  The unpaid portion of the Skip
Lease Payments shall bear interest at the rate of eight and one-half percent
(8.5%) per annum, or the maximum rate permitted by law, whichever is less, and
shall be payable over a sixty (60) month period commencing on the Effective
Date, as follows:  no principal or interest payments shall be payable by Maxum
from the Effective Date through August 31, 1993, interest only payments in the
amount of Thirteen Thousand Two Hundred Sixteen Dollars and One Cent
($13,216.01) shall be payable by Maxum from September 1, 1993 through
February 28, 1994, payments in the amount of Fifteen Thousand Dollars ($15,000)
shall be payable by Maxum from March 1, 1994 through December 31, 1994 and the
remaining principal and interest shall be amortized and payable in equal monthly
installments of Fifty-Two Thousand Seventy-Five Dollars and Nine Cents
($52,075.09) over the remaining forty-one (41) months of the term, as set forth
in the promissory note (the "Third Deferral Note") which shall be executed and
delivered by Maxum to GE on the Closing Date in the form attached hereto as
Schedule 2.8.  Notwithstanding the foregoing, Maxum shall prepay the Third
Deferral Note as required pursuant to Section 5.1(R) below.  In the event of
such prepayment, the monthly amount payable by Maxum from March 1, 1994 through
December 31, 1994 shall be adjusted accordingly.  The parties acknowledge that
the Third Deferral Note to be delivered by Maxum to GE on the Closing Date does
not establish a new debt from Maxum to GE but is intended to evidence GE's
deferral of Maxum's obligation to make the above-referenced lease payments
pursuant to the Equipment Leases and to set forth the terms upon which such
deferred lease payments shall be made to GE.

     2.9   Warrant.  On the Closing Date, MHC shall issue and deliver to GE its
common stock purchase warrant (the "Warrant"), in the form attached hereto as

($0.25) above the closing market price of MHC's stock on the day immediately

Promissory Notes in the forms attached hereto as Schedule 1.28, which promissory
notes shall be in the aggregate principal amount of Four Hundred One Thousand
Six Hundred Sixty-Seven Dollars and Ninety-Seven Cents ($401,667.97), GE
Contract Number 8506285-004 and Five Hundred One Thousand Four Hundred Forty-
Three Dollars and Forty-Three Cents ($501,443.43), GE Contract Number 8506382-
002, respectively, and shall be delivered by Maxum to GE at Closing.

     2.11  Satisfaction/Prepayment of Loans.  On the Closing Date GE shall loan
Maxum an additional amount equal to Two Million Two Hundred Fifty Thousand
Dollars ($2,250,000) (Loan Proceeds"), which loan proceeds shall be used for the

wire transfer of funds to the account specified in writing by Merrill Lynch. 
The outstanding principal amount shall bear interest at a rate equal to nine and
one-half percent (9.5%) per annum or the maximum rate which is permitted by law,
whichever is less, and shall be payable over a twelve (12) month period

the outstanding principal balance under the Merrill/Highline Promissory Note. 
Further, Maxum shall prepay the Merrill/Highline Promissory Note as required
pursuant to Section 5.1(R) below.  In the event of any such prepayment, the

outstanding principal balance.  

     2.12  Security Interest.  To secure the performance of the Liabilities by

of Default, MHC and the First-Tier Subsidiaries hereby irrevocably make,
constitute, and appoint GE (and all Persons designated by GE for that purpose)
as MHC's and the First-Tier Subsidiaries' true and lawful agent and
attorney-in-fact with power to sign the name of MHC or any of the First-Tier
Subsidiaries, as appropriate, on any supplemental documentation and to deliver
any supplemental documentation to such Persons as GE, in its sole discretion,
may elect.  MHC and the First-Tier Subsidiaries agree that a carbon,
photographic, photostatic or other reproduction of this Agreement or of a
Financing Statement is sufficient as a Financing Statement.  Notwithstanding the
foregoing provisions of this Section 5.1(M),  GE shall act (i) in a commercially
reasonable manner when exercising GE's rights pursuant to this Section 5.1(M),
and (ii) only as may be necessary in GE's reasonable judgment to protect or
preserve GE's rights under this Agreement and in the Scheduled Documents.

           Without limiting the generality of the foregoing, Maxum shall proceed
diligently following the Closing to obtain a duplicate certificate of title with
respect to that certain vehicle identified by serial number 1E9SE5748K1013009,
which duplicate certificate shall show GE as the lienholder.  Maxum shall
deliver such duplicate original certificate of title as soon as it is received
by Maxum or shall cause the appropriate state agency to deliver the duplicate
original certificate of title directly to GE.  Maxum shall further use its best
reasonable efforts to cause William L. MacKnight ("MacKnight") to issue a new
Promissory Note to MHC in the original principal amount of $110,625 on the same
terms and conditions as set forth in the original Promissory Note issued by
MacKnight to MHC on June 30, 1987, which efforts shall include MHC's agreement
to deliver the Lost Promissory Note Affidavit and Indemnity Agreement to
MacKnight in the form attached hereto as Schedule 5.2(M).

           (N) Insurance; Payment of Premiums.  MHC and the First-Tier
Subsidiaries shall, at their sole cost and expense, maintain in full force and
effect the types of insurance coverages set forth on Exhibit 4.1(L).

           (O) Litigation.  In the event any Pending Litigation shall result in
a final judgment adverse to MHC or any of the First-Tier Subsidiaries, MHC and
the First-Tier Subsidiaries shall promptly satisfy or bond-off such final
judgment.  Except as provided in Section 8.12(B) below, MHC and the First-Tier
Subsidiaries shall jointly and severally indemnify and hold GE and its
Affiliates harmless from any and all losses, claims, damages, costs, expenses
(including court costs and reasonable attorneys' fees) and obligations
(including, but not limited to, any loss of any right, title or interest of GE
in or to the Collateral) arising out of or related to, directly or indirectly,
any litigation, or the claim of any third party for alleged liabilities or
obligations of MHC or any of the First-Tier Subsidiaries arising out of
transactions or events affecting the Collateral; provided, however, that if GE
or any of its Affiliates intervene in such action, MHC and the First-Tier
Subsidiaries shall not be liable to GE or any of its Affiliates for any expenses
incurred by GE or any of its Affiliates, which for purposes of this
Section 5.1(O) shall include attorneys' fees or court costs incurred by GE or
any of its Affiliates but shall not include any damages or other losses incurred
by GE or any of its Affiliates in connection with such litigation.  MHC and the
First-Tier Subsidiaries shall not be liable to GE or its Affiliates for any
losses, claims, damages, costs, expenses and obligations which are caused by the
gross negligence, willful misconduct or other activities of GE as described in
Section 8.12(B) below.  

           (P) Monthly Reports.  MHC and the First-Tier Subsidiaries shall
maintain and deliver to GE on a timely basis in accordance with this Agreement
the monthly reports described in Section 2.4 above.

           (Q) Customer Contracts Entered Into After Closing Date.  In the event
that Maxum enters any contracts following the Closing Date for use of equipment
(i) that is leased by Maxum from GE, (ii) that is financed by GE or leased from
GE pursuant to installment sales agreements, capital leases or other financing
methods or (iii) that is or will be after it is acquired subject to GE's first
priority security interest then (a) Maxum shall require that such contract with
a hospital or other facility or entity that uses such equipment ("Customer")
expressly provide that (x) the contract is assignable to GE, and (y) the
Customer acknowledges and consents to GE's security interest in the contract,
and (b) such contract shall be entered into by MHSC and the Customer.  Maxum
shall promptly provide a copy of such Customer Contracts to GE.

           (R) Required Prepayments.  Maxum shall use no less than fifty percent
(50%) of the proceeds, net of reasonable selling expenses, from the sale of any
of the equipment or other property described in Exhibit 5.2(N) attached hereto,
for the purpose of prepaying first the outstanding principal amount under the
Merrill/Highline Promissory Note and then the outstanding principal amount under
the Third Deferral Note.

     5.2   Negative Covenants.  Without GE's prior written consent, which
consent may be withheld in GE's sole discretion (except as otherwise expressly
provided in Section 5.6 below to the contrary), MHC and the First-Tier
Subsidiaries covenant as follows:

           (A) Mergers.  Except as set forth in Exhibit 5.2(A) attached hereto,
neither MHC nor any of the First-Tier Subsidiaries shall, directly or
indirectly, by operation of law or otherwise, reorganize, merge or consolidate
or otherwise combine with any Person.

           (B) Investments and Acquisitions.  Neither MHC nor any of the First-
Tier Subsidiaries shall create, form or otherwise acquire any other Subsidiaries
(unless such  Subsidiaries are separate and separately funded).  Neither MHC nor
any of the First-Tier Subsidiaries shall make any loan or advances of money to
any Person or any investment, directly or indirectly (by way of transfer of
Property, contributions to capital, purchase of stock or securities or evidences
of Indebtedness, acquisition of the business or assets, or otherwise), in any
Person in amounts exceeding Two Hundred Thousand Dollars ($200,000) in any
single transaction or series of related transactions or One Million Dollars
($1,000,000) in the aggregate during any fiscal year of MHC.  Requests by MHC or

attached hereto, neither MHC nor any of the First-Tier Subsidiaries shall
voluntarily prepay any principal (including the making of any sinking fund
payment), interest or any other amount in respect of (1) any obligations that
are subordinate to MHC's or any of the First-Tier Subsidiaries' obligations to
GE, or (2) any other obligations.

           (E) ERISA.  Neither MHC nor any of the First-Tier Subsidiaries shall

of the First-Tier Subsidiaries shall at any time, permit any Plan described in
the Exhibit 4.1(R) to fail to comply with ERISA or other applicable laws in any
respect if such failure would have a Material Adverse Effect on MHC or any of
the First-Tier Subsidiaries.  Neither MHC nor any of the First-Tier Subsidiaries
shall at any time, permit any Plan maintained by any of them, to:  (1) engage in
any non-exempt "prohibited transaction," as such term is defined in Section 4975

have a Material Adverse Effect on MHC or any of the First-Tier Subsidiaries, or
(b) the imposition of a Lien on the Collateral pursuant to Section 4068 of
ERISA.

           (F) Amendments.  Except as set forth in Exhibit 5.2(F) attached
hereto, neither MHC nor any of the First-Tier Subsidiaries shall amend any
provision of any obligation that is subordinate to MHC's or any of the First-
Tier Subsidiaries' obligations to GE or any other obligation, if such amendment
would (1) affect any of the subordination provisions thereof, (2) advance the
date of any required payment or prepayment thereunder, (3) make any covenant
therein more burdensome to MHC or any of the First-Tier Subsidiaries, (4) reduce
any default or grace period therein provided, or (5) otherwise have a Material
Adverse Effect on the interests of GE.

           (G) Increase in Salaries.  Neither MHC nor any of the First-Tier
Subsidiaries shall in any fiscal year of MHC increase the aggregate salaries of

capitalized leases but excluding expenditures for routine repairs and
replacements) in excess of Two Hundred Thousand Dollars ($200,000) in any single
transaction or series of related transactions or One Million Dollars
($1,000,000) in the aggregate during any fiscal year of MHC.  Requests by MHC or
any of the First-Tier Subsidiaries to take any action that is prohibited by this
Section 5.2(H) shall comply with Section 5.6 below and shall be approved or
disapproved by GE in accordance with Section 5.6 below within ten (10) Business
Days following GE's receipt of MHC's or any of the First-Tier Subsidiaries'
request for consent.  Capital expenditures following the Closing Date for
equipment with an acquisition cost in excess of Fifty-Thousand Dollars ($50,000)
shall be made by MHSC and not MHC, any other First-Tier Subsidiaries or any
other Subsidiary.

           (I) Operating Leases.  Except as set forth on Exhibit 5.2(I) attached

the First-Tier Subsidiaries shall become the lessee under any operating lease if
the aggregate payments thereunder during any fiscal year of MHC exceed One
Hundred Thousand Dollars ($100,000).  Requests by MHC or any of the First-Tier
Subsidiaries to take any action that is prohibited by this Section 5.2(I) shall
comply with Section 5.6 below and shall be approved or disapproved by GE in
accordance with Section 5.6 below within ten (10) Business Days following GE's
receipt of MHC's or any of the First-Tier Subsidiaries' request for consent.

           (J) Transactions with Affiliates.  Except as specifically permitted
in this Agreement, neither MHC nor any of the First-Tier Subsidiaries shall
enter into, or be a party to, any transaction with any of MHC's or any of the
First-Tier Subsidiaries' respective officers, directors, employees, or
Affiliates of MHC or any of the First-Tier Subsidiaries, except for normal
employment arrangements and benefit programs on reasonable terms and no less
favorable to MHC or any of the First-Tier Subsidiaries than would obtain in a
comparable arm's length transaction with a Person not an officer, director,
employee or Affiliate of MHC or any of the First-Tier Subsidiaries; provided,
however, that MHC may issue common stock to capitalize any of its wholly-owned
First-Tier Subsidiaries.  Requests by MHC or any of the First-Tier Subsidiaries
to take any action that is prohibited by this Section 5.2(J) shall comply with
Section 5.6 below and shall be approved or disapproved by GE in accordance with
Section 5.6 below within ten (10) Business Days following GE's receipt of MHC's

           (L) Liens; Negative Pledges; Sales and Leasebacks.  Except for those

permit or suffer to exist, and MHC and the First-Tier Subsidiaries shall defend
the Collateral against and take such other action as is necessary to remove, any
Lien of any nature on the Collateral, whether now owned or hereafter acquired,
and MHC and the First-Tier Subsidiaries shall defend the right, title and
interest of GE in and to any of MHC's or any of the First-Tier Subsidiaries'

whomsoever.

           (M) Indebtedness.  Except for (i) Indebtedness outstanding on the

Two Hundred Thousand Dollars ($200,000) of Indebtedness in any single
transaction or series of related transactions or One Million Dollars
($1,000,000) of Indebtedness in the aggregate during any fiscal year of MHC. 
Notwithstanding the foregoing, Maxum expressly agrees that it shall not (i)
request or obtain any additional funds from Highline pursuant to that certain
Loan and Security Agreement entered into as of May 18, 1989 between Highline and
MTS, or otherwise, or (ii) take any action which would result in an increase or
material change in the potential liability of MHC or any First-Tier Subsidiary
as of the Closing Date pursuant to the guaranties identified in Exhibit 4.1(G),
including, without limitation, assigning or subleasing any lease that is
guaranteed pursuant thereto to any third party, without the prior written
consent of GE, which may be withheld in its sole discretion.  Further, Maxum
shall not restructure its outstanding obligations to Highline as of the Closing
Date without the prior written consent of GE; provided, however, that (i) if the
terms of such restructuring are on substantially the same terms as set forth in
the term sheet attached hereto as Exhibit 5.2(M) with no material modifications
thereto which could have a Material Adverse Effect on Maxum, and (ii) following
the restructure, the obligations of Maxum to Highline, XCC and/or their
successors or assigns are only comprised of those obligations generally
described in the Highline Term Sheet, which shall replace and/or subsume (e.g.,
pursuant to a modification and extension) all of the outstanding obligations of
Maxum pursuant to the Highline Documents, GE's prior written consent to the
restructuring transaction between Highline and MHC shall not be required.  MHC
shall provide GE with copies of all documents to be executed in connection with
the Highline restructuring at least five (5) business days prior to their
execution by MHC.  Requests by MHC or any of the First-Tier Subsidiaries to take
any action that is prohibited by this Section 5.2(M) shall comply with
Section 5.6 below and shall be approved or disapproved by GE in accordance with
Section 5.6 below within ten (10) Business Days following GE's receipt of MHC's
or any of the First-Tier Subsidiaries' request for consent.

           (N) Disposition of Property.  Except for the Property identified on
Exhibit 5.2(N) attached hereto which may be sold or transferred by MHC or the
First-Tier Subsidiaries without GE's prior written consent, neither MHC nor any

give GE notice of the sale of any Property identified in Exhibit 5.2(N).

           (O) Change in the Nature or Conduct of Business.  Neither MHC nor any
of the First-Tier Subsidiaries shall change the nature of their respective
businesses as conducted as of the Effective Date or engage in any businesses
other than the types of business in which they are engaged as of the Effective
Date without GE's prior written consent; provided, however, that the
introduction of additional products or services within or related to such lines
of business shall not be construed to be a new line of business.

           (P) Location of Units and Collateral; Books of Account.  All of the
Units and Collateral are, as of the Effective Date, located or used and operated
solely at the locations set forth in Exhibit 4.1(H), as applicable. 
Exhibit 4.1(H) shall be updated by the parties prior to the Closing Date to
reflect any change in the location where any of such Collateral was located,
used or operated as of the Effective Date and the location of any Collateral
acquired following the Effective Date and before the Closing Date.  Neither MHC
nor any of the First-Tier Subsidiaries nor any End User Customer shall operate
any Unit or keep any Collateral or any such books and records at any other
location following the Closing Date unless: (1) MHC or any of the First-Tier
Subsidiaries shall have given GE written notice of such removal and the new
location of such Unit, Collateral or such books and records, as applicable,
within ten (10) Business Days after its removal; (2) such other location is
within the continental United States of America; and (3) if such other location
is in a different state, Maxum has executed and delivered a UCC-1 Financing
Statement giving notice of GE's ownership rights in such Unit to be filed by GE.

           (Q) Security Interests in Future Entities.  Neither MHC nor any of
the First-Tier Subsidiaries shall form or create any joint venture or
partnership after the Effective Date unless (1) GE is granted a first priority
security interest in MHC's or the First-Tier Subsidiaries', as applicable,
respective interest in such joint venture or partnership and any distributions
to MHC or the First-Tier Subsidiaries from such joint venture or partnership,
and (2) GE consents to the formation or creation of such joint venture or
partnership without the granting of such security interest.

           (R) Capital Structure.  Except as disclosed in Exhibit 5.2(A)
attached hereto, neither MHC nor any of the First-Tier Subsidiaries shall make
any material change in (i) their respective capital structures, including the
issuance of any of their respective Stock, except (a) MHC's issuance of Stock to
GE pursuant to the terms of the Warrant, (b) MHC's issuance of a common stock
pursuant to a public offering, and (c) MHC's issuance of stock to Highline
pursuant to the terms of a common stock purchase warrant to acquire no more than
two hundred thousand (200,000) shares of MHC's common stock, no par value at an
exercise price to be determined by MHC.  Requests by MHC or any of the First-
Tier Subsidiaries to take any action that is prohibited by this Section 5.2(R)
shall comply with Section 5.6 below and shall be approved or disapproved by GE
in accordance with Section 5.6 below within ten (10) Business Days following
GE's receipt of MHC's or any of the First-Tier Subsidiaries' request for
consent.

           (S) End-User Customer Contracts.  Maxum shall not reduce, cancel,
compromise, extend, lessen, set-off against or defer the payments or other
obligations of the 
End-User Customer pursuant to the End-User Customer Contracts without the prior
written consent of GE, which consent may be withheld by GE in its sole
discretion.

     5.3   Payment of Charges.  Except as otherwise provided in Section 5.4
below or elsewhere in this Agreement and except as otherwise provided in the
next succeeding sentence, MHC and the First-Tier Subsidiaries shall pay all
charges for which they are liable, whether payable on account of the execution,
delivery or performance of this Agreement, the creation of any of the
Liabilities hereunder, by reason of any existing or hereafter enacted federal,
state or other regulation or statute, or otherwise, promptly when due where the
failure to so pay would have a Material Adverse Effect upon MHC or any of the
First-Tier Subsidiaries.  Except as provided in Section 5.4 below, MHC and the
First-Tier Subsidiaries shall pay promptly when due all withholding taxes for
which they are liable, whether relating to payment of employee wages or
otherwise (collectively, the "Withholding Charges").  MHC and the First-Tier
Subsidiaries shall jointly and severally indemnify GE and its Affiliates and
hold GE and its Affiliates harmless from and against liability in connection
with any and all charges (including any amount that may be asserted under
sections 3505 and 6672 of the IRC and any comparable provisions under state or
local law).  In the event that MHC or any of the First-Tier Subsidiaries fail to
pay any charges described in this Section 5.3 or fail to obtain promptly the
discharge of such charges, MHC and the First-Tier Subsidiaries shall so advise
GE in writing and, whether or not MHC or any of the First-Tier Subsidiaries so
advise GE, GE may, in its sole discretion, without waiving or releasing any
obligation or liability of MHC or any of the First-Tier Subsidiaries hereunder
or any Default or Event of Default, make such payment, or any part thereof, or
obtain such discharge and take any other action with respect thereto that GE
reasonably deems advisable; provided, however, that GE shall provide MHC with
ten (10) days' prior written notice before paying any charge of a type described
in this Section 5.3.  All amounts so paid by GE and any related expenses,
including reasonable attorneys' fees, court costs and other charges, shall be
payable, upon demand, by MHC and the First-Tier Subsidiaries to GE and shall be
additional Liabilities secured by Collateral.

     5.4   Contesting Charges.  Except as otherwise provided below and limited
only to those disputes which are in good faith in dispute, MHC or any of the
First-Tier Subsidiaries may dispute any charges without prior payment, even if
such nonpayment may cause a Lien to attach to MHC's or any of the First-Tier
Subsidiaries' assets, provided that MHC or any of the First-Tier Subsidiaries
shall have given GE written notice of said dispute and shall be diligently
contesting the same in good faith in an appropriate forum and proceeding.  If
such disputed charges are in excess of One Hundred Thousand Dollars ($100,000)
in the aggregate, at any time, MHC and the First-Tier Subsidiaries shall give GE
such additional assurances as GE reasonably deems necessary under the
circumstances.  If the charge disputed is a Withholding Charge, and during the
pendency of such dispute the appropriate taxing authority asserts liability
against GE in relation to the disputed Withholding Charge, then MHC and the
First-Tier Subsidiaries shall, if reasonably required by GE, immediately pay the
disputed Withholding Charge liability, and thereafter shall only contest such
Withholding Charge through an alternative method.

     5.5   Survival of Liabilities Upon Termination of Agreement.  Except as
otherwise expressly provided in this Agreement, no termination or cancellation
(regardless of cause or procedure) of this Agreement shall in any way affect or
impair the powers, obligations, duties, rights and Liabilities of MHC or any of
the First-Tier Subsidiaries or GE that accrued and remain unperformed as of the
Termination Date.

     5.6   Requests for GE's Consent.  Any request by MHC or any of the First-
Tier Subsidiaries for GE's written consent prior to taking any action prohibited
by Sections 5.2(B), 5.2(C), 5.2(G), 5.2(H), 5.2(I), 5.2(J), 5.2(M), 5.2(N) and
5.2(R) above as described in such sections, shall be in writing and shall
include (i) a reference to the covenant(s) relevant to the request, (ii) a
detailed description that is reasonably acceptable to GE of the requested
deviation from the covenant(s), and (iii) the reason for the requested deviation
from the covenant(s).  GE shall permit or refuse such request in writing within
the number of Business Days provided in each respective section identified in
Section 5.2 above, which approval shall not be unreasonably denied (except as
otherwise expressly provided in this Agreement to the contrary); provided,
however, that GE may reasonably request additional information regarding the
proposed action to be taken by MHC or any of the First-Tier Subsidiaries and
shall have an additional period of ten (10) Business Days following GE's receipt
of all such information to consider such information.  In the event GE does not
respond in writing to permit or refuse any request within the time periods
hereinabove stated, then the actions requested to be undertaken by Maxum as set
forth in its written request shall be deemed to be permitted by GE.

     7.2   Late Fee.

           (A) From and after the occurrence of an Event of Default that relates

under this Agreement or the Scheduled Documents, MHC and the First-Tier

           (B) MHC's or any of the First-Tier Subsidiaries' payment of any late
fee pursuant to Section 7.2(B) above shall not cure a Default or Event of
Default or limit any of GE's rights to pursue any of its remedies hereunder in
connection therewith.

     7.3   Remedies.  Upon the occurrence of an Event of Default, GE shall have
the following rights and remedies:

           (A) GE shall have the right to declare all or any portion of the
Liabilities immediately due and payable, whereupon all or any portion of the
Liabilities, as appropriate, shall become due and payable without presentment,
demand, protest or further notice of any kind, all of which are expressly waived
by MHC and the First-Tier Subsidiaries.

           (B) GE and its agents and representatives shall have the right to
enter upon the premises of MHC or any of the First-Tier Subsidiaries, and MHC
and the First-Tier Subsidiaries shall use reasonable efforts to cause GE and its
agents and representatives to have the right to enter upon the premises of any
other place or places where Collateral is located and kept through self-help and
without judicial process without first obtaining a final judgment or giving MHC
or any of the First-Tier Subsidiaries notice and opportunity for a hearing on
the validity of GE's claim and without any obligation to pay rent to MHC or any
of the First-Tier Subsidiaries or their lessees.

           (C) GE and its agents and representatives shall have the right to
remove the Collateral to the premises of GE or any agent of GE, for such time as
GE may desire, in order to collect or dispose of Collateral.

           (D) In addition to all of its other rights and remedies under this
Agreement and applicable law, GE shall have all of the rights and remedies of a
secured party under the UCC of the state in which such rights and remedies are
asserted, all of which rights and remedies shall be cumulative and none
exclusive, to the fullest extent permitted by law.

           (E) Until GE is able to effect a sale, lease or other disposition of
the Collateral, GE and its Affiliates shall have the right to use or operate the
Collateral, or any part thereof, to the extent that GE deems appropriate for the
purpose of preserving the Collateral or its value or for any other purpose
deemed appropriate by GE.  GE shall have no obligation to MHC or any of the
First-Tier Subsidiaries to maintain or preserve the rights of MHC or any of the
First-Tier Subsidiaries as against third parties with respect to the Collateral
while the Collateral is in the possession of GE.  GE may, if it so elects, seek
the appointment of a receiver or keeper to take possession of the Collateral and
to enforce any of GE's remedies with respect to such appointment without prior
notice or hearing.  GE and its Affiliates and agents shall act in a commercially
reasonable manner in enforcing their respective remedies pursuant to this
Section 7.3(E).  

           (F) GE shall have the right to sell, lease or otherwise dispose of
all or any Collateral in its then existing condition, or after any further
assembly, manufacturing or processing thereof, at public or private sale or
sales, with such notice as may be required by law, in lots or in bulk, for cash
or on credit, all as GE, acting in a commercially reasonable manner, may deem
advisable and as permitted by applicable law.  Such sales may be adjourned and
continued from time to time with or without notice.  GE and its agents and
representatives shall have the right to conduct such sales on MHC's or any of
the First-Tier Subsidiaries' premises or elsewhere and shall have the right to
use MHC's or any of the First-Tier Subsidiaries' premises, and MHC and the
First-Tier Subsidiaries shall use reasonable efforts to cause any lessee of the
Collateral to permit GE and its agents and representatives to conduct sales on
lessee's premises and use such lessee's premises, without charge for such sales
for such time as GE deems necessary or advisable.  The rights of MHC and the
First-Tier Subsidiaries under all licenses and certificates of need, to the
extent transferable, and all franchise agreements shall inure to GE's benefit. 
GE may purchase all or any part of the Collateral at public or, if permitted by
law, private sale and, in lieu of actual payment of such purchase price, may set
off the amount of such price against the Liabilities.  Except as otherwise
provided by law, the proceeds realized from the sale of any Collateral may be
applied by GE first to the reasonable costs, expenses and attorneys' fees and
expenses incurred by GE for collection and for acquisition, completion,
protection, removal, storage, sale and delivery of Collateral, and then to any
principal and interest due on the Liabilities, as GE, in its sole discretion,
may elect.  If any deficiency shall exist after the application of such
proceeds, MHC and the First-Tier Subsidiaries shall remain liable to GE
therefor.  GE and its agents and representatives shall act in a commercially
reasonable manner in enforcing its remedies pursuant to this Section 7.3(F).

     7.4   Notice of Disposition of Collateral.  Any notice required to be given
to GE of a sale, lease or other disposition of Collateral, or any other intended
action by MHC or any of the First-Tier Subsidiaries, which is given in
accordance with Section 8.11 below, shall require at least fifteen (15) days
written notice prior to such proposed action, or such longer period as shall be
specified by applicable law, shall constitute commercially reasonable and fair
notice thereof to MHC or any of the First-Tier Subsidiaries.

     7.5   Right of Set-Off.  Upon the occurrence and during the continuance of
any Event of Default, GE and its Affiliates are hereby authorized at any time
and from time to time, to the fullest extent permitted by law, upon three (3)
Business Days prior written notice to MHC or any of the First-Tier Subsidiaries,
to set-off, appropriate and apply any and all funds in the possession of GE or
its Affiliates, all deposits (general or special, time or demand, provisional or
final) at any time held and other Indebtedness at any time owing by GE or its
Affiliates to or for the credit or the account of MHC or any of the First-Tier
Subsidiaries, as applicable, against any and all of the Liabilities of MHC or
any of the First-Tier Subsidiaries now or hereafter existing that are then due
and payable, whether by maturity or acceleration.  The rights of GE and its
Affiliates under this Section 7.5 are in addition to any other rights and
remedies (including, without limitation, other rights of set-off) which GE may
have.

     7.6   Appointment of GE as Maxum's Lawful Attorney.  MHC and the First-Tier
Subsidiaries hereby irrevocably designate, make, constitute and appoint GE and
all Persons designated by GE as their true and lawful agent and attorney-in-fact
upon the occurrence and during the continuance of an Event of Default for the
purposes set forth in this Section 7.6.  Accordingly, upon the occurrence and
during the continuance of an Event of Default, GE or GE's agent designated by GE
for purposes of this Section 7.6 may, without notice to MHC or any of the First-
Tier Subsidiaries, and at such time or times as GE or said agent in its sole
discretion may determine, in the name of MHC or any of the First-Tier
Subsidiaries or GE: (a) take control, in any manner, of any item of payment or
proceeds of Collateral; (b) prepare, file, and sign MHC's or any of the First-
Tier Subsidiaries' respective names on any proof of claim or similar document in

sign MHC's or any of the First-Tier Subsidiaries' respective names on any notice

discretion, to fulfill MHC's or any of the First-Tier Subsidiaries' respective
obligations under this Agreement; (e) endorse MHC's or any of the First-Tier
Subsidiaries' respective names upon any of the items of payment or proceeds of
the Collateral and deposit the same to the account of GE on account of
Liabilities; (f) endorse MHC's or any of the First-Tier Subsidiaries' respective
names upon any chattel paper, document, instrument, invoice, freight bill, bill
of lading or similar document or agreement relating to Collateral; and (g) use
the information recorded on or contained in any data processing equipment and
computer hardware and software relating to Collateral to which MHC or any of the
First-Tier Subsidiaries has access.  MHC and the First-Tier Subsidiaries hereby
ratify all that GE shall lawfully do or cause to be done by virtue hereof.  The
power of attorney is a power coupled with an interest and shall be irrevocable. 
GE shall act (a) in a commercially reasonable manner when exercising its rights
pursuant to this Section 7.6, and (b) only as necessary in the reasonable
judgment of GE to protect its rights under this Agreement, the Scheduled
Documents and to the Collateral.

otherwise, this Agreement or any of MHC's or any of the First-Tier Subsidiaries'
rights, title, interests, remedies, powers or duties hereunder or thereunder
without the prior written consent of GE, which shall not be unreasonably
withheld.  Any sale, assignment or transfer not consented to by GE shall be null
and void and of no force or effect.  MHC and the First-Tier Subsidiaries hereby
consent to GE's sale, assignment, transfer or other disposition of this
Agreement or of any or all of GE's rights, title, interests, obligations,
remedies, powers or duties hereunder.  All of the terms and provisions of this
Agreement and the Scheduled Documents shall be binding upon and shall inure to
the benefit of and be enforceable by the respective successors and assigns of
the parties hereto.

     8.2   Expenses.  Notwithstanding the provisions of this Section 8.2 set

including the disbursements and fees of their respective attorneys, accountants
and advisors, incidental to (a) the preparation and negotiation of this
Agreement and the Scheduled Documents, and (b) the closing of the transactions
contemplated by this Agreement.

           Except as specifically set forth above, if, upon the occurrence and
during the continuance of an Event of Default, GE or its Affiliates employs
counsel for advice or other representation or incurs other professional costs
and expenses in connection with:

           (A) any litigation, contest, dispute, suit, case, proceeding or
action (whether instituted by GE, MHC or any of the First-Tier Subsidiaries or
any other Person) in any way relating to Collateral, this Agreement, the
Scheduled Documents or MHC's or any of the First-Tier Subsidiaries' affairs,
including any litigation, contest, dispute, suit, case, proceeding or action,
and any appeal or review thereof, in connection with a case commenced by or
against MHC or any of the First-Tier Subsidiaries under the Bankruptcy Code or
any other applicable federal or state bankruptcy, insolvency or similar law;

           (B) any attempt to enforce any rights of GE against MHC or any of the

Code or any other applicable federal or state bankruptcy, insolvency or similar
law; and/or

           (C) the protection, collection, sale, liquidation or other
disposition of Collateral; 

then, in any such event, the reasonable professional fees arising from such
services, and all reasonable expenses, costs, charges and other fees incurred by
GE arising in connection with or relating to any of the events or actions
described in this Section 8.2 shall be payable by MHC and the Subsidiaries to GE
on demand and shall constitute Liabilities secured by the Collateral.

its Affiliates harmless from and against any and all liabilities with respect to
or resulting from any delay in paying or omission to pay any such professional
costs, expenses, fees and taxes.

     8.3   Waivers by GE; Cumulative Remedies.  GE's failure, at any time or
times hereafter, to require strict performance by MHC or any of the First-Tier
Subsidiaries of any provision of this Agreement, shall not waive, affect or
diminish any right of GE thereafter to demand strict compliance and performance
therewith.  Any suspension or waiver by GE of an Event of Default under this
Agreement shall not suspend, waive or affect any other Event of Default by MHC
or any of the First-Tier Subsidiaries under this Agreement whether the same is
prior or subsequent thereto and whether of the same or of a different type. 
None of the undertakings, agreements, warranties, covenants and representations
of MHC and the First-Tier Subsidiaries contained in this Agreement nor any Event
of Default by MHC or any of the First-Tier Subsidiaries under this Agreement
shall be deemed to have been suspended or waived by GE unless such suspension or
waiver is in a writing signed by GE which designates the specific suspension or
waiver.  The rights and remedies hereunder are cumulative and may be exercised
singly or concurrently, and are not exclusive of any rights and remedies
provided by law or which GE would otherwise have.

     8.4   Waivers by Maxum.  Except as otherwise provided in this Agreement and
except where waiver is prohibited as a matter of applicable law, MHC and the
First-Tier Subsidiaries waive: (a) presentment, demand and protest and notice of
presentment, protest, default, nonpayment, maturity, release, compromise,
settlement, extension or renewal of any or all commercial paper, accounts,
contract rights, documents, instruments, chattel paper and guaranties at any
time held by GE under or pursuant to which MHC or any of the First-Tier
Subsidiaries may in any way be liable, and MHC and the First-Tier Subsidiaries
hereby ratify and confirm whatever GE may do in this regard; (b) notice prior to
taking possession or control of the Collateral or, so long as GE remains a party
to this Agreement, any bond or security that might be required by any court
prior to allowing GE to exercise any of GE's remedies; and (c) the benefit of
all valuation, appraisement and exemption laws.  If and to the extent that any
of the Liabilities shall be an obligation of guaranty or suretyship, then the
following waivers shall apply:

           (A) MHC and the First-Tier Subsidiaries agree that no election to
proceed in one form of action or against any party or on any obligation shall
constitute a waiver of GE's right to proceed in any other form of action for a
deficiency, except to the extent GE realizes payment by such action,
notwithstanding the effect of such action upon MHC's or any of the First-Tier
Subsidiaries' rights of subrogation, reimbursement or indemnity, if any, against
any Person.  MHC and the First-Tier Subsidiaries hereby subordinate any and all
claims that they may have by way of subrogation or otherwise to the payment in
full of all Liabilities; and

           (B) MHC and the First-Tier Subsidiaries agree that GE shall be under
no obligation and expressly waive the right to require GE: (a) to marshall any
assets in favor of MHC or any of the First-Tier Subsidiaries, (b) to proceed
first against any guarantor or any Property of guarantor or against any
collateral, (c) to enforce first any other guaranty obligations with respect to,

itself and that may lighten MHC's or any of the First-Tier Subsidiaries' burden,
any right to which MHC and the First-Tier Subsidiaries hereby expressly waive.

     8.5   Further Assurances.  In addition to the acts recited herein and
contemplated to be performed, executed and/or delivered by MHC or any of the
First-Tier Subsidiaries, MHC and the First-Tier Subsidiaries hereby agree, at
any time, and from time to time, to perform, execute and/or deliver to GE upon
request, in form and substance acceptable to GE, any and all such further acts,
additional instruments, or further assurances as may be reasonably necessary or
proper to (a) promptly implement the intent of the parties under this Agreement,
(b) promptly correct any defect, error or omission which may be discovered in
this Agreement or any Scheduled Document, and execute any and all additional
documents as may be reasonably requested by GE to correct such defect, error or
omission, (c) assure GE a valid Lien and security interest under the Security
Agreement on the Collateral referenced in the Security Agreement in accordance
with the priorities set forth therein, (d) create, perfect, preserve, maintain
and protect the Liens and security interests created or intended to be created
pursuant to the Security Agreement, and (e) provide the rights and remedies to
GE granted or provided for by this Agreement.  MHC and the First-Tier
Subsidiaries shall pay the costs of any recording or filing of any such
documents if required.  

     8.6   Severability.  Wherever possible, each provision of this Agreement
shall be interpreted in a manner as to be effective and valid under applicable
law.  If any provision of this Agreement shall be held to be prohibited by or
invalid under applicable law in any jurisdiction, such provision, as to such
jurisdiction, shall be ineffective only to the extent of such provision and the
remaining provisions of this Agreement shall remain unaffected and in full force
and effect, and such prohibition and invalidity in such jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

     8.7   Parties.  This Agreement shall be binding upon and shall inure to the
benefit of the respective successors and assigns of MHC and the First-Tier
Subsidiaries and GE including any trustee or interim trustee of MHC or any of
the First-Tier Subsidiaries appointed pursuant to Bankruptcy Code section 1104
or sections 701 and 702.  This provision, however, shall not be deemed to modify
Section 8.1.

     8.8   Conflict of Terms.  The provisions of any other related agreement and
any schedule or exhibit thereto or to this Agreement are incorporated in this
Agreement as if set forth in full by this reference.  Except as otherwise
provided in this Agreement by specific reference to the applicable provision of
this Agreement, if any provision contained in this Agreement conflicts or is
inconsistent with any provision in any other related agreement, the provision
contained in this Agreement shall govern and control.

     8.9   Governing Law; Consent to Jurisdiction and Venue.  This Agreement and
the Scheduled Documents shall be interpreted by and construed in accordance with
the laws of the State of New York, and the laws of the State of New York shall
govern each and every issue relating to the transactions contemplated herein,
including the validity or enforceability of this Agreement.  MHC AND THE FIRST-
TIER SUBSIDIARIES HEREBY CONSENT TO PERSONAL JURISDICTION, WAIVE ANY OBJECTION
AS TO JURISDICTION OR VENUE, AND AGREE NOT TO ASSERT ANY DEFENSE BASED ON LACK
OF JURISDICTION OR VENUE, IN ANY STATE OR FEDERAL COURT SITTING IN THE BOROUGH
OF MANHATTAN, STATE OF NEW YORK.  Service of process on MHC or any of the First-
Tier Subsidiaries or GE in any action arising out of or relating to any
Agreement contemplated herein shall be effective if mailed to such party at the
address listed in Section 8.11.  Nothing herein shall preclude GE or MHC or any
of the First-Tier Subsidiaries from bringing suit or taking other legal action
in any other jurisdiction.

     8.10  MUTUAL WAIVER OF JURY TRIAL.  BECAUSE DISPUTES ARISING IN CONNECTION
WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED
BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND
FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT
THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE,
TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
SUIT OR PROCEEDING BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER
THIS AGREEMENT OR ANY OTHER AGREEMENT.

     8.11  Notice.  Except as otherwise provided herein, whenever it is provided
herein that any notice, demand, request, consent, approval, declaration or other
communication shall or may be given to or served upon any of the parties by
another, or whenever any of the parties desires to give or serve upon another
any communication with respect to this Agreement, each such notice, demand,
request, consent, approval, declaration or other communication shall be in

  shall deliver to the Company at its principal office at 14850 Quorum Drive,
  Suite 400, Dallas, Texas 75240 or at the office or agency designated by the
  Company pursuant to Section 12, (i) a written notice of Holder's election to

  certificates so delivered shall be, to the extent possible, in such
  denomination or denominations as such Holder shall request in the notice and
  shall be registered in the name of Holder or, subject to Section 9, such
  other name as shall be designated in the notice.  This Warrant shall be
  deemed to have been exercised and such certificate or certificates shall be
  deemed to have been issued, and Holder or any other Person so designated to
  be named therein shall be deemed to have become a holder of record of such
  shares for all purposes, as of the date the notice, together with the payment
  as set forth below, and this Warrant are received by the Company as described
  above and all taxes required to be paid by Holder, if any, pursuant to
  Section 2.2 prior to the issuance of such shares have been paid or agreed to
  be paid when finally determined.

                Payment of the Warrant Price shall be made at the option of the
  Holder by certified or official bank check.

          2.2   Payment of Taxes.  All shares of Common Stock issuable upon the
  exercise of this Warrant pursuant to the terms hereof shall be validly
  issued, fully paid and nonassessable.  The Company shall pay all expenses in
  connection with, and all taxes and other governmental charges that may be
  imposed with respect to, the issue or delivery thereof, unless such tax or
  charge is imposed by law upon Holder, in which case such taxes or charges
  shall be paid by Holder.  The Company shall not be required, however, to pay
  any tax or other charge imposed in connection with any transfer involved in
  the issuance of any certificate for shares of Common Stock issuable upon
  exercise of this Warrant in any name other than that of Holder, and in such
  case the Company shall not be required to issue or deliver any stock
  certificate until such tax or other charge has been paid or it has been
  established to the satisfaction of the Company that no such tax or other
  charge is due.

  upon the exercise of this Warrant (other than a holder who acquires such
  shares after the same have been publicly sold pursuant to a Registration
  Statement under the Securities Act or sold pursuant to Rule 144 thereunder),
  shall continue to be entitled with respect to such shares to all rights to
  which it would have been entitled as Holder under Sections 9, 10, 13, and 16
  of this Warrant.  The Company shall, at the time of each exercise of this
  Warrant upon the request of the holder of the shares of Common Stock issued
  upon such exercise hereof, acknowledge in writing, in form reasonably
  satisfactory to such holder, its continuing obligation to afford to such
  holder all such rights and subject to any burdens; provided, however, that if
  such holder shall fail to make any such request, such failure shall not
  affect the continuing obligation of the Company to afford to such holder all
  such rights.

  3.      TRANSFER, DIVISION AND COMBINATION

          3.1   Transfer.  This Warrant shall be nontransferable other than to
  a division, subsidiary or affiliate of GE Medical except by merger of the
  Holder with another entity or otherwise by operation of law.  Subject to
  compliance with Section 9 following said period of nontransferability,
  transfer of this Warrant and all rights hereunder, in whole or in part, shall
  be registered on the books of the Company to be maintained for such purpose,
  upon surrender of this Warrant at the principal office of the Company
  referred to in Section 2.1 or the office or agency designated by the Company
  pursuant to Section 12, together with a written assignment of this Warrant
  substantially in the form of Exhibit B hereto duly executed by Holder or its
  agent or attorney and funds sufficient to pay any transfer taxes payable upon
  the making of such transfer.  Upon such surrender and, if required, such
  payment, the Company shall, subject to Section 9, execute and deliver a new
  Warrant or Warrants in the name of the assignee or assignees and in the
  denomination specified in such instrument of assignment, and shall issue to
  the assignor a new Warrant evidencing the portion of this Warrant not so
  assigned, and this Warrant shall promptly be cancelled.  A Warrant, if
  properly assigned in compliance with Section 9, may be exercised by a new
  Holder for the purchase of shares of Common Stock without having a new
  Warrant issued.  If requested by the Company, a new Holder shall acknowledge
  in writing, in form reasonably satisfactory to the Company, such Holder's
  continuing obligations under Section 9 of this Warrant.

          3.2   Division and Combination.  Subject to Section 9, this Warrant
  may be divided or combined with other Warrants upon presentation hereof at
  the aforesaid office or agency of the Company, together with a written notice
  specifying the names and denominations in which new Warrants are to be
  issued, signed by Holder or its agent or attorney.  Subject to compliance
  with Section 3.1 and with Section 9, as to any transfer which may be involved
  in such division or combination, the Company shall execute and deliver a new
  Warrant or Warrants in exchange for the Warrant or Warrants to be divided or
  combined in accordance with such notice.

          3.3   Expenses.  The Company shall prepare, issue and deliver at its
  own expense (other than transfer taxes) the new Warrant or Warrants under
  this Section 3.

          3.4   Maintenance of Books.  The Company shall maintain, at its
  aforesaid office or agency, books for the registration, and the registration
  of transfer, of this Warrant.

  4.      ADJUSTMENTS

          The number of shares of Common Stock for which this Warrant is
  exercisable, or the price at which such shares may be purchased upon exercise
  of this Warrant shall be subject to adjustment from time to time as set forth
  in this Section 4.  The Company shall give each Holder notice of any event
  described below which requires an adjustment pursuant to this Section 4 at
  the time of such event.

          4.1   Stock Dividends, Subdivisions, Combinations and
  Reclassifications.  If at any time the Company shall with respect to its
  Common Stock or Convertible Securities:

                (a)  pay a dividend or make distribution to holders of the
          Company's securities generally of Additional Shares of Common Stock
          or Convertible Securities other than convertible indebtedness or
          convertible Preferred Stock (in which event such Additional Shares of
          Common Stock issuable upon exchange or conversion shall be deemed
          distributed),

                (b)  subdivide its outstanding shares of Common Stock into a
          larger number of shares of Common Stock,

                (c)  combine its outstanding shares of Common Stock into a
          smaller number of shares of Common Stock, or

                (d)  reclassify its Common Stock (other than a change in par
          value, or from par value to no par value) into shares of Common Stock
          and shares of any other class of stock; and, if the outstanding
          shares of Common Stock shall be changed into a larger or smaller
          number of shares of Common Stock as a part of such reclassification,
          such change shall be deemed a subdivision or combination, as the case
          may be, of the Outstanding shares of Common Stock within the meaning
          of this Section 4.1., then (i) the number of shares of Common Stock
          for which this Warrant is exercisable after the occurrence of any
          such event shall be equal to (A) the maximum number of shares of
          Common Stock underlying this Warrant prior to the occurrence of any
          such event, multiplied by (B) the number of Fully Diluted Outstanding
          shares of Common Stock after any such event, divided by the number of
          Fully Diluted Outstanding shares of Common Stock prior to any such
          event, and (ii) the Current Warrant Price shall be adjusted to equal
          the Current Warrant Price multiplied (A) by the number of shares of
          Common Stock for which this Warrant is exercisable immediately prior
          to the adjustment divided by (B) the number of shares for which this
          Warrant is exercisable immediately after such adjustment.  Any
          increased number of shares of Common Stock subject to this Warrant
          resulting from application of the foregoing shall be allocated
          ratably among all shares of Common Stock subject to this Warrant
          prior to each such event and the shares (including the newly
          allocated shares) not subject to clause (i) of Section 2.1 shall
          remain subject to the conditions precedent to exercise described in
          clause (ii) of Section 2.1.

          4.2   Other Provisions Applicable to Adjustments under this Section. 
  The following provisions shall be applicable to the making of adjustments of
  the number of shares of Common Stock for which this Warrant is exercisable
  provided for in this Section 4:

                (a)  When Adjustments to Be Made.  The adjustments required by
          this Section 4 shall be made whenever and as often as any specified
          event requiring an adjustment shall occur.  For the purpose of any
          adjustment, any specified event shall be deemed to have occurred at
          the close of business on the date of its occurrence.

                (b)  When Adjustment Not Required.  If the Company shall take a
          record of the holders of its Common Stock for the purpose of
          entitling them to receive a dividend or distribution or subscription
          or purchase rights and shall, thereafter and before the distribution
          to stockholders thereof, legally abandon its plan to pay or deliver
          such dividend, distribution, subscription or purchase rights, then
          thereafter no adjustment shall be required by reason of the taking of
          such record and any such adjustment previously made in respect
          thereof shall be rescinded and annulled.

  5.      NOTICES TO WARRANT HOLDERS

          5.1   Notice of Adjustments.  Whenever the number of shares of Common
  Stock for which this Warrant is exercisable, or whenever the price at which a
  share of such Common Stock may be purchased upon exercise of this Warrant,
  shall be adjusted pursuant to Section 4, the Company shall forthwith prepare
  a certificate to be executed by the chief financial officer of the Company
  setting forth, in reasonable detail, the event requiring the adjustment and
  the method by which such adjustment was calculated, specifying the number of
  shares of Common Stock for which this Warrant is exercisable, and any change
  in the purchase price or prices thereof, after giving effect to such
  adjustment or change.  The Company shall promptly cause a signed copy of such
  certificate to be delivered to each Holder in accordance with Section 16.2. 
  The Company shall keep at its office or agency designated pursuant to Section
  12 copies of all such certificates and cause the same to be available for
  inspection at said office during normal business hours by any Holder or any
  prospective purchaser of a Warrant designated by a Holder thereof.

          5.2   Notice of Certain Corporate Action.  The Holder shall be
  entitled to the same rights to receive notice of corporate action as any
  holder of Common Stock.

  6.      NO IMPAIRMENT

          The Company shall not by any action including, without limitation,
  amending its certificate of incorporation or through any reorganization,
  transfer of assets, consolidation, merger, dissolution, issue or sale of
  securities or any other voluntary action, avoid or seek to avoid the
  observance or performance of any of the terms of this Warrant, but will at
  all times in good faith assist in the carrying out of all such terms and in
  the taking of all such actions as may be necessary or appropriate to protect
  the rights of Holder against impairment.  Without limiting the generality of
  the foregoing, the Company will (a) not increase the par value, if any, of
  any shares of Common Stock receivable upon the exercise of this Warrant above
  the amount payable therefor upon such exercise immediately prior to such
  increase in par value, (b) take all such action as may be reasonably
  necessary or appropriate in order that the Company may validly and legally
  issue fully paid and nonassessable shares of Common Stock upon the exercise
  of this Warrant, and (c) use its best efforts to obtain all such
  authorizations, exemptions or consents from any public regulatory body having
  jurisdiction thereof as may be necessary to enable the Company to perform its
  obligations under this Warrant.

          Upon the request of Holder, the Company will at any time during the
  period this Warrant is outstanding acknowledge in writing, in form
  satisfactory to Holder, the continuing validity of this Warrant and the
  obligations of the Company hereunder.

  7.      RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
          APPROVAL OF ANY GOVERNMENTAL AUTHORITY

          From and after the Closing Date, the Company shall at all times
  reserve and keep available for issuance upon the exercise of Warrants such
  number of its authorized but unissued shares of Common Stock as will be
  sufficient to permit the exercise in full of all outstanding Warrants.  All
  shares of Common Stock which shall be so issuable, when issued upon exercise
  of any Warrant and payment therefor in accordance with the terms of such
  Warrant, shall be duly and validly issued and fully paid and nonassessable,
  and not be subject to preemptive rights.

          Before taking any action which would cause an adjustment reducing the
  Current Warrant Price below the then par value, if any, of the shares of
  Common Stock issuable upon exercise of the Warrants, the Company shall take
  any corporate action which may be reasonably necessary in order that the
  Company may validly and legally issue fully paid and nonassessable shares of
  such Common Stock at such adjusted Current Warrant Price.

          Before taking any action which would result in an adjustment in the
  number of shares of Common Stock for which this Warrant is exercisable or in
  the Current Warrant Price, the Company shall obtain all such authorizations
  or exemptions thereof, or consents thereto, as may be reasonably necessary
  from any public regulatory body or bodies having jurisdiction thereof.

          If any shares of Common Stock required to be reserved for issuance
  upon exercise of warrants require registration or qualification with any
  governmental authority under any federal or state law (otherwise than as
  provided in Section 9) before such shares may be so issued, the Company will
  in good faith and as expeditiously as possible and at its expense endeavor to
  cause such shares to be duly registered or qualified; provided that the
  provisions of Section 9 shall govern with respect to Company's obligation to
  effect the registration of its securities under the Securities Act and any
  state securities laws.

  8.      TAKING OF RECORD; STOCK AND WARRANT TRANSFER BOOKS

          In the case of all dividends or other distributions by the Company to
  the holders of its Common Stock with respect to which any provision of
  Section 4 refers to the taking of a record of such holders, the Company will
  in each such case take such a record and will take such record as of the
  close of business on a Business Day.  The Company will not at any time,
  except upon dissolution, liquidation or winding up of the Company, close its
  stock transfer books or Warrant transfer books so as to result in preventing
  or delaying the exercise or transfer of any Warrant.

  9.      RESTRICTIONS ON TRANSFERABILITY

          This Warrant shall not be transferable except to a division,
  subsidiary or affiliate of GE Medical or by merger of the Holder with another
  entity or otherwise by operation of law.  Furthermore, this Warrant and the
  Warrant Stock shall not be transferred, hypothecated or assigned before
  satisfaction of the conditions specified in this Section 9, which conditions
  are intended to ensure compliance with the provisions of the Securities Act
  and state law, with respect to the Transfer of this Warrant or any Warrant
  Stock.  Holder, by acceptance of this Warrant, agrees to be bound by the
  provisions of this Section 9.  Furthermore, Holder, by acceptance of this
  Warrant and by acceptance and delivery of the Subscription Form in the form
  of Exhibit A hereto, represents and warrants to the Company for its reliance
  in connection with issuing this Warrant and the Warrant Stock, respectively,
  that (i) Holder is acquiring the Warrant, and if applicable, the Warrant
  Stock for Holder's own account for investment and not for sale or other
  disposition thereof; (ii) Holder understands that such securities are not
  registered under the Securities Act and must be held indefinitely unless
  subsequently registered under the Securities Act or unless an exemption from
  such registration is available; (iii) Holder, by reason of its business and
  financial experience has the capacity to protect its own interests in
  connection with purchase and transfer of such securities and is able to bear
  the economic risk thereof; and (iv) the Company has made available to Holder
  all documents and information regarding an investment in such securities
  requested by or on behalf of Holder, including but not limited to all
  publicly available information on file with the Commission.

          9.1   Restrictive Legend.

                (a) Except as otherwise provided in this Section 9, each
          certificate for Warrant Stock initially issued upon the exercise of

          subsequent transferee of any such certificate, shall be stamped or
          otherwise imprinted with a legend in substantially the following
          form:

                   are subject to the conditions specified in a certain Common
                   Stock Purchase Warrant dated as of __________, 1993,
                   originally issued by Maxum Health Corp.  No transfer of the
                   shares represented by this certificate shall be valid or
                   effective until such conditions and any requirements of
                   state law have been fulfilled.  A copy of the form of said
                   Warrant is on file with the Secretary of Maxum Health Corp. 
                   The holder of this certificate, by acceptance of this
                   certificate, agrees to be bound by the provisions of such
                   Warrant.

                   b) Except as otherwise provided in this Section 9, each
              Warrant shall be stamped or otherwise imprinted with a legend in
              substantially the following form:

                   This Warrant and its underlying securities have not been
                   registered under the Securities Act of 1933, as amended, and
                   may not be transferred in violation of such Act or state
                   law, the rules and regulations thereunder or the provisions
                   of this Warrant.

        9.2   Notice of Proposed Transfers; Requests for Registration.  Prior
  to any Transfer or attempted Transfer of any Warrants or any shares of
  Warrant Stock, the holder of such Warrants or Warrant Stock shall give ten
  days prior written notice (a "Transfer Notice") to the Company of such
  holder's intention to effect such Transfer, describing the manner and
  circumstances of the proposed Transfer, and shall obtain and deliver to the
  Company an opinion in form and substance reasonably satisfactory to the
  Company (addressed to the Company and upon which the Company may rely) from
  counsel to such holder who shall be reasonably satisfactory to the Company,
  that the proposed Transfer of such Warrants or such Warrant Stock may be
  effected without registration under the Securities Act and any applicable
  state securities law(s).  After receipt of the Transfer Notice and opinion,
  the Company shall, within five Business Days thereof, so notify the holder of
  such Warrants or Warrant Stock and such holder shall thereupon be entitled to
  Transfer such Warrants or such Warrant Stock, in accordance with the terms of
  the Transfer Notice.  Each certificate, if any, evidencing such shares of
  Warrant Stock issued upon such Transfer shall bear the restrictive legend set
  forth in Section 9.1(a), and each Warrant issued upon such Transfer shall
  bear the restrictive legend set forth in Section 9.1(b), unless in the
  opinion of such counsel such legend is not required in order to ensure
  compliance with the Securities Act and any applicable state securities
  law(s).  The holder of the Warrants or the Warrant Stock, as the case may be,
  giving the Transfer Notice shall not be entitled to transfer and shall not
  transfer such Warrants or such Warrant Stock until (i) the Company receives a
  written statement of investment intent and sophistication from the proposed
  Transferee in substance substantially similar to the final sentence of the
  first paragraph of Section 9 and (ii) such holder receives notice from the
  Company under this Section 9.2.

              The Holders of Warrants and Warrant Stock shall have the right to
  request registration of such Warrant Stock pursuant to Sections 9.3 and 9.4.

        9.3   Required Registration.  The rights ("Required Registration") of
  holders of Warrants and/or Warrant Stock under this Section 9.3 shall become
  effective only on and after the date 90 days prior to the Exercise Date and
  shall expire on the Expiration Date.  After receipt of a written request from
  the holders of Warrants and/or Warrant Stock representing at least an
  aggregate of fifty percent (50%) of the total of (i) all shares of Warrant
  Stock then subject to issuance upon exercise of all Warrants and (ii) all
  shares of Warrant Stock then Outstanding having an aggregate Current Market
  Price in excess of $400,000, requesting that the Company effect the
  registration of Warrant Stock issuable upon the exercise of such holder's
  Warrants or of any of such holder's Warrant Stock under the Securities Act
  and specifying the intended method or methods of disposition thereof, the
  Company shall promptly notify all holders of Warrants and Warrant Stock in
  writing of the receipt of such request and each such holder, in lieu of
  exercising its rights under Section 9.4, may elect (by written notice
  specifying the intended method or methods of disposition of Warrant Stock
  sent to the Company within ten Business Days from the date of such holder's
  receipt of the aforementioned Company's notice) to have such holder's shares
  of Warrant Stock included in such registration thereof pursuant to this
  Section 9.3.  Thereupon the Company shall, as expeditiously as is possible,
  use its best efforts to effect the registration under the Securities Act of
  all shares of Warrant Stock which the Company has been so requested to
  register by such holders for sale, all to the extent required to permit the
  disposition (in accordance with the intended method or methods thereof, as
  aforesaid) of the Warrant Stock so registered; provided, however, that the
  Company shall not be required to effect more than one registration of any
  Warrant Stock pursuant to this Section 9.3.  


              (a)  Suspension of Registration.  

                   If the Company has been requested to effect a Required
              Registration, whether or not a Registration Statement with
              respect thereto has been filed or has become effective, and
              furnishes to the Holder requesting such registration a copy of a
              resolution of the Board of Directors of the Company certified by
              the Secretary of the Company stating that in the good faith
              judgment of the Board of Directors it would be seriously
              detrimental to the Company and its stockholders for such
              Registration Statement (i) to be filed on or before the date such
              filing would otherwise be required hereunder, (ii) to become
              effective, or (iii) to remain effective as long as such
              Registration Statement would otherwise be required to remain
              effective, the Company shall have the right to defer such filing
              or effectiveness or to suspend such effectiveness for a period of
              not more than 120 days; provided that during such time the
              Company may not file a Registration Statement for securities to
              be issued and sold for its own account or that of anyone other
              than the Holder or Holders requesting such Required Registration;
              and provided, further, that if effectiveness of a Registration
              Statement is suspended pursuant to this provision, the period of
              such suspension shall be added to the end of the period that such
              Registration Statement would otherwise be required to be
              effective hereunder so that the aggregate number of days that
              such Registration Statement is required to remain effective
              hereunder shall remain unchanged.

              (b)  Hold-Back Agreements.

                   (i)  Restrictions on Public Sale By Holder of Registrable
              Securities.  Each Holder whose registrable securities are covered
              by a Registration Statement filed pursuant to this Warrant
              agrees, if requested by the managing underwriters in an
              underwritten offering, not to effect any public sale or
              distribution of securities of the Company of the same class as
              the securities included in such Registration Statement, including
              a sale pursuant to Rule 144 under the Securities Act (except as
              part of such underwritten registration), during the 10-day period
              prior to, and during the period from 90 to 180 days, as
              recommended by the underwriter, beginning on, the effective date
              of such Registration Statement, to the extent timely notified in
              writing by the Company or the managing underwriters; provided,
              however, that the holders of the Registrable Securities will not
              be subject to the hold-back restrictions of this Section if the
              Company and the other holders of the Company's equity securities
              have not complied with the provisions of subsection (b) (ii)
              below.


                   (ii)  Restrictions on Sale of Equity Securities by the
              Company and Others.  The Company agrees (1) not to effect any
              public offer, sale or distribution of its equity securities
              (i) during the 10-day period prior to, and during the 90-day
              period beginning with, the effectiveness of a Registration
              Statement filed under this Warrant to the extent timely notified
              in writing by a holder of registrable securities or the managing
              underwriters (except as part of such registration, if permitted,
              or pursuant to registrations on Forms S-4 or S-8 or any successor
              form to such Forms or the issuance of Common Stock pursuant to
              warrants or employee stock options outstanding on the date
              hereof) and (2) to use its best efforts to cause each holder of
              its privately placed equity securities purchased from the Company
              at any time on or after the date of this Agreement to agree not
              to effect any public sale or distribution of any such securities
              during such period, including a sale pursuant to Rule 144 under
              the Securities Act (except as part of such registration, if
              permitted).

        9.4   Incidental Registration.  The rights of holders of Warrants
  and/or Warrant Stock under this Section 9.4 shall become effective only on
  and after the Exercise Date and shall expire on the Expiration Date.  If the
  Company at any time proposes to file on its behalf and/or on behalf of any of
  its security holders ("the demanding security holders") a Registration
  Statement under the Securities Act on any form (other than a Registration
  Statement required under section 9.3 or a Registration Statement on Form S-4
  or S-8 or any successor form for securities to be offered in a transaction of
  the type referred to in Rule 145 under the Securities Act or to employees of
  the Company pursuant to any employee benefit plan or to existing holders of
  the Company's debt or equity securities in any exchange or rights offering,
  respectively) for the general registration of securities to be sold for cash
  with respect to its Common Stock or any other class of equity security (as
  defined in Section 3(a)(11) of the Exchange Act) of the Company, it will give
  written notice to all holders of Warrants or Warrant Stock at least 30 days
  before the initial filing with the Commission of such Registration Statement,
  which notice shall set forth the intended method of disposition of the
  securities proposed to be registered by the Company.  The notice shall offer
  to include in such filing the aggregate number of shares of Warrant Stock,
  and the number of shares of Common Stock for which this Warrant is
  exercisable, as such holders may request.  Nothing herein shall preclude the
  Company from discontinuing the registration of its securities being effected
  on its behalf or on behalf of the demanding security holders at any time
  prior to the effective date of the registration relating thereto.

              Each holder of any such Warrants or any such Warrant Stock
  desiring to have Warrant Stock registered under this Section 9.4 shall advise
  the Company in writing within 30 days after the date of receipt of such offer
  from the Company, setting forth the amount of such Warrant Stock for which
  registration is requested.  The Company shall thereupon include in such
  filing the number of shares of Warrant Stock for which registration is so
  requested, subject to the next sentence, and shall use its best efforts to
  effect registration under the Securities Act of such shares.  If the managing
  underwriter of a proposed public offering shall advise the Company in writing
  that, in its opinion, the distribution of the shares of Common Stock into
  which the Warrants are exercisable and the Warrant Stock requested to be
  included in the registration concurrently with the securities being
  registered by the Company or such demanding security holder would materially
  and adversely affect the distribution of such securities by the Company or
  such demanding security holder, then all demanding security holders (other
  than any selling security holder who requested such registration and the
  Company (unless such Registration Statement was filed at the request of a
  demanding security holder)) shall reduce the amount of securities each
  intended to distribute through such offering on a pro rata basis.  Except as
  otherwise provided in Section 9.6, all expenses of such registration shall be
  borne by the Company.

        9.5   Registration Procedures.  If the Company is required by the
  provisions of this Section 9 to use its best efforts to effect the
  registration of any of its securities under the Securities Act, the Company
  will, as expeditiously as possible:

              (a)  prepare and file with the Commission a Registration
        Statement with respect to such securities and use its best efforts to
        cause such Registration Statement to become and remain effective for a
        period of time required for the disposition of such securities by the
        holders thereof;

              (b)  prepare and file with the Commission such amendments and
        supplements to such Registration Statement and the prospectus used in
        connection therewith as may be necessary to keep such Registration
        Statement effective and to comply with the provisions of the Securities
        Act with respect to the sale or other disposition of all securities
        covered by such Registration Statement until the earlier of such time
        as all of such securities have been disposed of in a public offering or
        the expiration of 180 days;

              (c)  furnish to any selling security holders such number of
        copies of a summary prospectus or other prospectus, including a
        preliminary prospectus, in conformity with the requirements of the
        Securities Act, and such other documents, as such selling security
        holders may reasonably request;

              (d)  use its best efforts to register or qualify the securities
        covered by such Registration Statement under such other securities or
        blue sky laws of such jurisdictions within the United States and Puerto
        Rico as each Holder of such securities shall reasonably request in
        light of such Holder's intended plan of distribution (provided,
        however, that in the event the Company's shares are traded on a
        national securities exchange or national market system such
        jurisdictions shall not exceed ten for an underwritten offering or
        three for a shelf registration, and provided further that the Company
        shall not be obligated to qualify as a foreign corporation to do
        business under the laws of any jurisdiction in which it is not then
        qualified or to file any general consent to service of process or
        subject itself to taxation in any such jurisdiction), and do such other
        reasonable acts and things as may be required of it to enable such
        holder to consummate the disposition in such jurisdiction of the
        securities covered by such Registration Statement;

              (e)  if requested by a majority (in amount of underlying and
        outstanding shares ) of the Holders of Warrants or Warrant Stock being
        included in such registration, use its best efforts to obtain from
        either a nationally recognized underwriter or investment banker or an
        underwriter or investment banker reasonably acceptable to such Holders
        a firm commitment (pursuant to an underwriting agreement in customary
        form) to underwrite the public offering of the securities covered by
        such Registration Statement;

              (f)  furnish, at the request of any holder requesting
        registration of Warrant Stock pursuant to Section 9.3, on the date that
        such shares of Warrant Stock are delivered to the underwriters for sale
        pursuant to such registration or, if such Warrant Stock is not being
        sold through underwriters, on the date that the Registration Statement
        with respect to such shares of Warrant Stock becomes effective, (1) a
        copy of an opinion, dated such date, of the independent counsel
        representing the Company for the purposes of such registration,
        addressed to the underwriters, if any, and to the holders making such
        request, stating that such Registration Statement has become effective
        under the Securities Act and that (i) to the best knowledge of such
        counsel, no stop order suspending the effectiveness thereof has been
        issued and no proceedings for that purpose have been instituted or are
        pending or contemplated under the Securities Act, (ii) the Registration
        Statement, the related prospectus, and each amendment or supplement
        thereto, comply as to form in all material respects with the
        requirements of the Securities Act and the applicable rules and
        regulations of the Commission thereunder (except that such counsel need
        express no opinion as to financial statements or statistical data
        contained therein), (iii) the descriptions in the Registration
        Statement or the prospectus, or any amendment or supplement thereto, of
        all legal matters and contracts and other legal documents or
        instruments are accurate and, to the knowledge of such counsel, fairly
        present the information required to be shown, and (iv) such counsel
        does not know of any legal or governmental proceedings, pending or
        contemplated, required to be described in the Registration Statement or
        prospectus, or any amendment or supplement thereto, which are not
        described as required, nor of any contracts or documents or instruments
        of a character required to be described in the Registration Statement
        or prospectus, or any amendment or supplement thereto, or to be filed
        as exhibits to the Registration Statement which are not described and
        filed or incorporated by reference as required; such counsel shall also
        confirm that nothing has come to his attention to lead him to believe
        that either the Registration Statement or the prospectus, or any
        amendment or supplement thereto (other than financial material or
        statistical data as to which such counsel need make no statement)
        contains any untrue statement of a material fact or omits to state a
        material fact required to be stated therein or necessary to make the
        statements therein, in light of the circumstances in which made, not
        misleading; and (2) a letter dated such date, from the independent
        certified public accountants of the Company, addressed to the
        underwriters, if any, and to the holder making such request and, if
        such accountants refuse to deliver such letter to such holder, then to
        the Company stating that they are independent certified public
        accountants within the meaning of the Securities Act and that, in the
        opinion of such accountants, the financial statements and other
        financial data of the Company included in the Registration Statement or
        the prospectus, or any amendment or supplement thereto, comply as to
        form in all material respects with the applicable accounting
        requirements of the Securities Act.  Such opinion of counsel shall
        additionally cover such other legal matters with respect to the
        registration in respect of which such opinion is being given as the
        underwriters may reasonably request.  Such letter from the independent
        certified public accountants shall additionally cover such other
        financial matters (including information as to the period ending not
        more than five Business Days prior to the date of such letter) with
        respect to the registration in respect of which such letter is being
        given as the holders holding a majority of the Warrant Stock being so
        registered may reasonably request;

              (g)  enter into customary agreements (including an underwriting
        agreement in customary form) and take such other actions as are
        reasonably required in order to expedite or facilitate the disposition
        of the securities covered by Registration Statement; and

              (h)  otherwise use its best efforts to comply with all applicable
        rules and regulations of the Commission, and make available to its
        security holders, as soon as reasonably practicable, but not later than
        18 months after the effective date of the Registration Statement, an
        earnings statement covering the period of at least 12 months beginning
        with the first full month after the effective date of such Registration
        Statement, which earnings statements shall satisfy the provisions of
        Section 11(a) of the Securities Act.

              (i)  notify each selling Holder of such registrable securities,
        at any time when a prospectus relating thereto is required to be
        delivered under the Securities Act, of the occurrence of an event
        requiring the preparation of a supplement or amendment to such
        prospectus so that, as thereafter delivered to the purchasers of the
        securities covered by the Registration Statement, such prospectus will
        not contain an untrue statement of a material fact or omit to state any
        material fact required to be stated therein or necessary to make the
        statements therein not misleading and promptly make available to each
        selling Holder any such supplement or amendment.

              It shall be a condition precedent to the obligation of the
  Company to take any action pursuant to this Section 9 in respect of the
  securities which are to be registered at the request of any holder of
  Warrants or Warrant Stock that such holder shall furnish to the Company such
  information regarding the securities held by such holder and the intended
  method of disposition thereof as the Company shall reasonably request and as
  shall be required in connection with the action taken by the Company.

              Each selling Holder agrees that, upon receipt of any notice from
  the Company of the happening of any event of the kind described in
  Section 9.5(i) hereof, such selling Holder will forthwith discontinue
  disposition of Registrable Securities pursuant to the registration statement
  covering the securities covered by the Registration Statement until such
  selling Holder's receipt of the copies of the supplemented or amended
  prospectus contemplated by Section 9.5(i) hereof, and, if so directed by the
  Company such selling Holder will deliver to the Company all copies, other
  than permanent file copies then in such selling Holder's possession, of the
  most recent prospectus covering the securities covered by Registration
  Statement at the time of receipt of such notice.  If the Company shall give
  such notice, the Company shall extend the period during which such
  Registration Statement shall be maintained effective by the number of days
  during the period from and including the date of the giving of notice
  pursuant to Section 9.5(i) hereof to the date when the Company shall make
  available to the selling Holders of the securities covered by such
  Registration Statement a prospectus supplemented or amended to conform with
  the requirements of Section 9.5(i) hereof.

        9.6   Expenses; Limitations on Registration.  All expenses incurred in
  complying with Section 9, including, without limitation, all registration and
  filing fees (including all expenses incident to filing with the NASD,
  printing expenses, fees and disbursements of counsel for the Company, the
  reasonable fees and expenses of one counsel for the selling security holders
  (selected by those holding a majority of the shares being registered),
  expenses of any special audits incident to or required by any such
  registration and expenses of complying with the securities or blue sky laws
  of any jurisdictions pursuant to Section 9.5(d), shall be paid by the
  Company, except that 

              (a) all such expenses in connection with any amendment or
        supplement to the Registration Statement or prospectus filed more than
        180 days after the effective date of such Registration Statement
        because any holder of Warrant Stock has not effected the disposition of
        the securities requested to be registered shall be paid by such holder;

              (b) if the Warrant Stock is sold in an underwritten offering at a
        gross price (before underwriting discounts or commissions) of less than
        $4.00 per share, the persons selling Warrant Stock in such offering
        shall pay a pro rata share of all registration and filing fees,
        reasonable fees and disbursements of Company counsel and accountants,
        and other out-of-pocket costs incurred by the Company in connection
        with such offering; and

              (c) the Company shall not be liable for any fees, discounts or
        commissions to any underwriter or any fees or disbursements of counsel
        for any underwriter in respect of the securities sold by such holder of
        Warrant Stock.

        9.7   Indemnification.

              (a)  In the event of any registration of any of the Warrant Stock
        under the Securities Act pursuant to this Section 9, the Company shall
        indemnify and hold harmless the holder of such Warrant Stock, such
        holder's directors and officers, and each other Person (including each
        underwriter) who participated in the offering of such Warrant Stock and
        each other Person, if any, who controls such holder or such
        participating Person within the meaning of the Securities Act, against
        any losses, claims, damages or liabilities, joint or several, to which
        such holder or any such director or officer or participating Person or
        controlling Person may become subject under the Securities Act or any
        other statute or at common law, insofar as such losses, claims, damages
        or liabilities (or actions in respect thereof) arise out of or are
        based upon (i) any alleged untrue statement of any material fact
        contained, on the effective date thereof, in any Registration Statement
        under which such securities were registered under the Securities Act,
        any preliminary prospectus or final prospectus contained therein, or
        any amendment or supplement thereto, or (ii) any alleged omission to
        state therein a material fact required to be stated therein or
        necessary to make the statements therein not misleading, and shall
        reimburse such Holder or such director, officer or participating Person
        or controlling Person for any legal or any other expenses reasonably
        incurred by such holder or such director, officer or participating
        Person or controlling Person in connection with investigating or
        defending any such loss, claim, damage, liability or action; provided,
        however, that the Company shall not be liable in any such case to the
        extent that any such loss, claim, damage or liability arises out of or
        is based upon any alleged untrue statement or alleged omission made in
        such Registration Statement, preliminary prospectus, prospectus or
        amendment or supplement in reliance upon and in conformity with written
        information furnished to the Company by such holder specifically for
        use therein or (in the case of any registration pursuant to Section
        9.3) so furnished for such purposes by any underwriter.  Such indemnity
        shall remain in full force and effect regardless of any investigation
        made by or on behalf of such holder or such director, officer or
        participating Person or controlling Person, and shall survive the
        transfer of such securities by such holder.

              (b) Each holder of any Warrant Stock, by acceptance thereof,
        agrees to indemnify and hold harmless the Company, its directors and
        officers and each other Person, if any, who controls the Company within
        the meaning of the Securities Act against any losses, claims, damages
        or liabilities, joint or several, to which the Company or any such
        director or officer or any such Person may become subject under the
        Securities Act or any other statute or at common law, insofar as such
        losses, claims, damages or liabilities (or actions in respect thereof)
        arise out of or are based upon information in writing provided to the
        Company by such Holder of such Warrant Stock contained, on the
        effective date thereof, in any Registration Statement under which
        securities were registered under the Securities Act at the request of
        such holder, any preliminary prospectus or final prospectus contained
        therein, or any amendment or supplement thereto; provided, however,
        that such Holder's obligation under this Section 9.7(b) to indemnify
        and hold harmless the Company shall in no event exceed the damage
        attributable solely to the inclusion of such written information in
        such Registration Statement, preliminary prospectus, final prospectus,
        or amendment or supplement suffered by the Person or Persons whose
        claims gave rise to such losses, claims, damages or liabilities.

                   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 furnished in 
        writing by persons specifically for inclusion in any prospectus or
        Registration Statement.

              (c)  If the indemnification provided for in this Section 9 from
        the indemnifying party is unavailable to an indemnified party hereunder
        in respect of any losses, claims, damages, liabilities or expenses
        referred to herein, then the 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 losses,
        claims, damages, liabilities or expenses in such proportion as is
        appropriate to reflect the relative fault of the indemnifying party and
        indemnified parties in connection with the actions which resulted in
        such losses, claims, damages, liabilities or expenses, as well as any
        other relevant equitable considerations.  The relative fault of such
        indemnifying party and indemnified parties shall be determined by
        reference to, among other things, whether any action in question,
        including any untrue or alleged untrue statement of a material fact or
        omission or alleged omission to state a material fact, has been made
        by, or relates to information supplied by, such indemnifying party or
        indemnified parties, and the parties' relative intent, knowledge,
        access to information and opportunity to correct or prevent such
        action.  The amount paid or payable by a party under this Section 9 as
        a result of the losses, claims, damages, liabilities and expenses
        referred to above shall be deemed to include any legal or other fees or
        expenses reasonably incurred by such party in connection with any
        investigation or proceeding.

              The parties hereto agree that it would not be just and equitable
  if contribution pursuant to this Section 9.7(c) were determined by pro rata
  allocation or by any other method of allocation which does not take account
  of the equitable considerations referred to in the immediately preceding
  paragraph.  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.

              Notwithstanding any other provisions of this Warrant, the Company
  shall not be liable in any case to the extent that any loss, claim, damage,
  liability or expense arises out of or is based upon any untrue statement or
  alleged untrue statement or omission or alleged omission in any Registration
  Statement or prospectus, if such untrue statement or alleged untrue
  statement, omission or alleged omission is corrected in an amendment or
  supplement to the Registration Statement and the Holder thereafter fails to
  deliver such Registration Statement or prospectus as so amended or
  supplemented prior to or concurrently with the sale of the securities covered
  by such Registration Statement to the person asserting such loss, claim,
  damage, liability or expense after the Company had furnished such Holder with
  a sufficient number of copies of the same.

        9.8   Termination of Restrictions.  Notwithstanding the foregoing
  provisions of Section 9, the restrictions imposed by this Section upon the
  transferability after the Exercise Date of the Warrants and the Warrant Stock
  and the legend requirements of Section 9.1 shall terminate as to any
  particular Warrant or share of Warrant Stock (i) when and so long as such
  security shall have been effectively registered under the Securities Act and
  disposed of pursuant thereto or (ii) when the Company shall have received an
  opinion of counsel reasonably satisfactory to it that such legend is not
  required in order to ensure compliance with the Securities Act.  Whenever
  after the Exercise Date the restrictions imposed by Section 9 shall terminate
  as to this Warrant, as hereinabove provided, the Holder hereof shall be
  entitled to receive from the Company, at the expense of the Company, a new
  Warrant bearing the following legend in place of the restrictive legend set
  forth hereon:

                   "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
                   CONTAINED IN SECTION 9 HEREOF TERMINATED ON                
                   ,     ,  AND ARE OF NO FURTHER FORCE AND EFFECT."

  All Warrants thereafter issued upon registration of transfer, division or
  combination of, or in substitution for, any Warrant or Warrants entitled to
  bear such legend shall have a similar legend endorsed thereon.  Whenever the
  restrictions imposed by this Section shall terminate as to any share of
  Warrant Stock, as hereinabove provided, the holder thereof shall be entitled
  to receive from the Company, at the Company's expense, a new certificate
  representing such Warrant Stock not bearing the restrictive legend set forth
  in Section 9.1(a).

        9.9   Listing on Securities Exchange.  If and so long as the Company
  shall list any shares of Common Stock on NASDAQ or any securities exchange,
  it will, at its expense, list thereon, maintain and, when necessary, increase
  such listing of, all shares of Common Stock issued or, to the extent
  permissible under the applicable NASDAQ or securities exchange rules,
  issuable upon the exercise of this Warrant concurrently with registration of
  such shares under the Securities Act so long as any shares of Common Stock
  shall be so listed during any such Exercise Period.

        9.10  Certain Limitations on Registration Rights.  Notwithstanding the
  other provisions of Section 9:

                   (i) the Company shall not be obligated to register the
              Warrant Stock of any Holder if (x) in the opinion of counsel to
              the Company reasonably satisfactory to the Holder and its counsel
              (or, if the Holder has engaged an investment banking firm, to
              such investment banking firm and its counsel), the sale or other
              disposition of such Holder's Warrant Stock, in the manner
              proposed by such Holder (or by such investment banking firm), may
              be effected without registering such Warrant Stock under the
              Securities Act, and (y) the failure of the Company to register
              such Warrant Stock will not result in a reduction in the net
              proceeds to be received by such Holder in connection with such
              sale or other disposition; and

                   (ii) the Company shall not be obligated to register the
              Warrant Stock of any Holder pursuant to Section 9.3, if the
              Company has had a registration statement, under which such Holder
              had a right to have its Warrant Stock included pursuant to
              Sections 9.3 or 9.4, declared effective within one year prior to
              the date of the request pursuant to Section 9.3; provided,
              however, that if any Holder elected to have shares of its Warrant
              Stock included under such registration statement but some or all
              of such shares were excluded pursuant to the penultimate sentence
              of Sections 9.3 or 9.4, then such one-year period shall be
              reduced to six months.

        9.11  Selection of Managing Underwriters.  The managing underwriter or
  underwriters for any offering of Warrant Stock to be registered pursuant to
  Section 9.3 shall be selected by the Company and shall be reasonably
  acceptable to the Holders of a majority of the shares being so registered
  (other than any shares being registered pursuant to Section 9.4).

  10.   SUPPLYING INFORMATION

        The Company shall cooperate with each Holder of a Warrant and each
  holder of Warrant Stock in supplying such information as may be reasonably
  necessary for such Holder to complete and file any information reporting
  forms presently or hereafter required by the Commission as a condition to the
  availability of an exemption from the Securities Act for the sale of any
  Warrant or Restricted Common Stock.

  11.   LOSS OR MUTILATION

        Upon receipt by the Company from any Holder of evidence reasonably
  satisfactory to it of the ownership of and the loss, theft, destruction or
  mutilation of this Warrant and indemnity reasonably satisfactory to it (it
  being understood that the written agreement of GE Medical shall be sufficient
  indemnity) and in case of mutilation upon surrender and cancellation hereof,
  the Company will execute and deliver in lieu hereof a new Warrant of like
  tenor to such Holder; provided, in the case of mutilation, no indemnity shall
  be required if this Warrant in identifiable form is surrendered to the
  Company for cancellation.

  12.   OFFICE OF THE COMPANY

        As long as any of the Warrants remain outstanding, the Company shall
  maintain an office or agency (which may be the principal executive offices of
  the Company) where the Warrants may be presented for exercise, registration
  of transfer, division or combination as provided in this warrant.  The
  Company shall notify Holder in writing prior to any change of the address of
  the office at which the Warrants may be presented.

  13.   FINANCIAL AND BUSINESS INFORMATION

        13.1  Information.  Except during any period when the Company is a
  Public Company (as hereinafter defined), it will deliver to each Holder, as
  soon as practicable after the end of each quarter and in any event within 50
  days thereafter, one copy of an unaudited consolidated balance sheet,
  statement of income and statement of cash flow of the Company and its
  Subsidiaries for such period setting forth in each case in comparative form
  the figures for the corresponding periods in the previous fiscal years.  Such
  financial statements shall be prepared by the Company in accordance with GAAP
  as modified by Regulation S-X and shall be accompanied by the certification
  of the Company's chief executive officer or chief financial officer that such
  financial statements are complete and correct and present fairly the
  consolidated financial position, results of operations and cash flow of the
  Company and its Subsidiaries as at the end of such period and for such
  year-to-date period, as the case may be.

              For purposes of this Section 13, the term "Public Company" shall
  mean a company (i) that is subject to the reporting requirements of Section
  15(d) of the Exchange Act, or (ii) any of whose securities are registered
  pursuant to Section 12(b) or 12(g) of the Exchange Act.

        13.2  Annual Information.  Except during any period when the Company is
  a Public Company, it will deliver to each Holder as soon as practicable after
  the end of each fiscal year of the Company, and in any event within 105 days
  thereafter, one copy of:

                   (i)   an audited consolidated balance sheet of the Company
              and its Subsidiaries as at the end of such year, and

                   (ii) audited consolidated statements of income and retained
              earnings and cash flow of the Company and its Subsidiaries for
              such year;

  setting forth in each case in comparative form the figures for the
  corresponding periods in the previous fiscal year; all prepared in accordance
  with GAAP, and which audited financial statements shall be accompanied by (i)
  an opinion thereon of the independent certified public accountants regularly
  retained by the Company, or any other firm of independent certified public
  accountants of recognized national standing selected by the Company and (ii)
  a report of such independent certified public accountants confirming, or
  describing the agreed upon procedures applied to the Company's schedules
  computing, any adjustment, made pursuant to Section 4 during such year.  Such
  report shall include a description of any errors determined by the
  accountants in the Company's schedules.

        13.3  Filings.  The Company will file on or before the required date
  all required regular or periodic reports (pursuant to the Exchange Act) with
  the Commission and will deliver to Holder promptly upon their becoming
  available one copy of each report, notice or proxy statement sent by the
  Company to its stockholders generally, and of each regular or periodic report
  (pursuant to the Exchange Act) and any Registration Statement, prospectus or
  written communication (other than transmittal letters) pursuant to the
  Securities Act, filed by the Company with (i) the Commission or (ii) any
  securities exchange on which shares of Common Stock are listed (provided,
  however, that the Company may request filing extensions pursuant to Rule
  12b-25 under the Securities and Exchange Act of 1934, as amended).

  14.   APPRAISAL

        The determination of the Appraised Value per share of Common Stock
  shall be made by an investment banking firm of nationally recognized standing
  selected by the Company and acceptable to the Holder.  If the investment
  banking firm selected by the Company is not acceptable to the Holder and the
  Company and the Holder cannot agree on a mutually acceptable investment
  banking firm, then the Holder and the Company shall each choose one such
  investment banking firm and the respective chosen firms shall agree on
  another investment banking firm which shall make the determination.  The
  Company shall retain, at its sole cost, such investment banking firm as may
  be necessary for the determination of Appraised Value required by the terms
  of this Warrant.

  15.   LIMITATION OF LIABILITY

        No provision hereof, in the absence of affirmative action by the Holder
  to purchase shares of Common Stock, and no enumeration herein of the rights
  or privileges of Holder hereof, shall give rise to any liability of such
  Holder for the purchase price of any Common Stock or as a stockholder of the
  Company, whether such liability is asserted by the Company or by creditors of
  the Company.




  16.   MISCELLANEOUS

        16.1  Nonwaiver and Expenses.  No course of dealing or any delay or
  failure to exercise any right hereunder on the part of the Company shall
  operate as a waiver of such right or otherwise prejudice the Company's
  rights, powers or remedies.  No course of dealing or any delay or failure to
  exercise any right hereunder on the part of the Holder shall operate as a
  waiver of such right or otherwise prejudice the Holder's rights, powers or
  remedies.  If the Company fails to make, when due, any payments provided for
  hereunder, or fails to comply with any other provision of this Warrant, the
  Company shall pay to the Holder such amounts as shall be sufficient to cover
  any costs and expenses including, but not limited to, reasonable attorneys'
  fees, including those of appellate proceedings, incurred by the Holder in
  collecting any amounts due pursuant hereto or in otherwise enforcing any of
  its rights, powers or remedies hereunder.

        16.2  Notice Generally.  Any notice, demand, request, consent,
  approval, declaration, delivery or other communication hereunder to be made
  pursuant to the provisions of this Warrant shall be sufficiently given or
  made if in writing and either delivered (i) in person with receipt
  acknowledged, (ii) by facsimile transmission, with receipt electronically
  confirmed during normal business hours of recipient, and that is confirmed by
  sending, no later than one (1) Business Day following such transmission, a
  copy of such facsimile, by registered or certified mail, return receipt
  requested, postage prepaid, or (iii) by registered or certified mail, return
  receipt requested, postage prepaid, addressed as follows:

              (a)  If to any Holder or holder of Warrant Stock, at its last
        known address or facsimile transmission number appearing on the books
        of the Company maintained for such purpose.

              (b)  If to the Company at

                   Maxum Health Corp.
                   14850 Quorum Drive
                   Suite 400
                   Dallas, Texas  75240
                   FAX (214)716-7850

  or at such other address as may be substituted by notice given as herein
  provided.  The giving of any notice required hereunder may be waived in
  writing by the party entitled to receive such notice.  Every notice, demand,
  request, consent, approval declaration, delivery or other communication
  hereunder shall be deemed to have been duly given or served on the date on
  which personally delivered, with receipt acknowledged or sent by facsimile
  with receipt electronically confirmed during normal business hours of
  recipient, or three (3) Business Days after the same shall have been
  deposited in the United States mail.  Failure or delay in delivering copies
  of any notice, demand, request, approval, declaration, delivery or other
  communication to the person designated above to receive a copy shall in no
  way adversely affect the effectiveness of such notice, demand, request,
  approval, declaration, delivery or other communication.

        16.3  Remedies.  Each holder of Warrant and Warrant Stock, in addition
  to being entitled to exercise all rights granted by law, including recovery
  of damages, will be entitled to specific performance of its rights under
  Section 9 of this Warrant.  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 Section 9 of this Warrant and hereby agrees to waive
  the defense in any action for specific performance that a remedy at law would
  be adequate.  

        16.4  Successors and Assigns.  Subject to the provisions of Sections
  3.1 and 9, this Warrant and the rights evidenced hereby shall inure to the
  benefit of and be binding upon the successors of the Company and the
  successors and assigns of Holder.  The provisions of this Warrant are
  intended to be for the benefit of all Holders from time to time of this
  Warrant, and shall be enforceable by any such Holder.

        16.5  Amendment.  This Warrant and all other Warrants may be modified
  or amended or the provisions hereof waived with the written consent of the
  Company and the Holder.

        16.6  Severability.  Wherever possible, each provision of this Warrant
  shall be interpreted in such manner as to be effective and valid under
  applicable law, but if any provision of this Warrant shall be prohibited by
  or invalid under applicable law, such provision shall be ineffective to the
  extent of such prohibition or invalidity, without invalidating the remainder
  of such provision or the remaining provisions of this Warrant.

        16.7  Headings.  The headings used in this Warrant are for the
  convenience of reference only and shall not, for any purpose, be deemed a
  part of this Warrant.

        16.8  Governing Law; Service of Process.  In all respects, including
  all matters of construction, validity and performance, this Agreement and the
  obligations arising hereunder shall be governed by, and construed and
  enforced in accordance with, the laws of the state of the Company's
  incorporation applicable to contracts made and performed in such state,
  without regard to the principles thereof regarding conflict of laws, and any
  applicable laws of the United States of America.  

        16.9  MUTUAL WAIVER OF JURY TRIAL.  BECAUSE DISPUTES ARISING IN
  CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND
  ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE COMPANY AND
  HOLDER HEREOF WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN
  ARBITRATION RULES), THE COMPANY AND HOLDER HEREOF DESIRE THAT THEIR DISPUTES
  PERTAINING TO THE WARRANT BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE
  LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE
  JUDICIAL SYSTEM AND OF ARBITRATION, THE COMPANY AND HOLDER HEREOF WAIVE ALL
  RIGHT TO TRIAL BY JURY IN ANY ACTION SEEKING ENFORCEMENT OF THE PARTIES'
  RIGHTS UNDER THIS WARRANT.

        IN WITNESS WHEREOF, the Company has caused this Warrant to be duly
  executed and its corporate seal to be impressed hereon and attested by its
  Secretary or an Assistant Secretary.

               (b)  In the event that the Merger does not occur immediately

automatically and immediately rescinded. 

          2.2  DELIVERIES.  At the Closing, AHS, Maxum, InSight and GE Medical

                                    ARTICLE 3
                  REPRESENTATIONS AND WARRANTIES REGARDING AHS

          As used in this Agreement (I) the term "MATERIAL ADVERSE EFFECT"
means, with respect to a party, a material adverse effect on the business,
assets, results of operations, financial condition or prospects of such party
and its subsidiaries, taken as a whole, or in the ability of such party to
perform its obligations hereunder, and (II) the term "SUBSIDIARY" when used with
respect to any party means any corporation or other organization, whether
incorporated or unincorporated, of which such party or any other subsidiary of
such party is a general partner or of which at least a majority of the
securities or other interests having by their terms ordinary voting power to
elect a majority of the Board of Directors or others performing similar
functions with respect to such corporations or other organizations is directly
or indirectly owned or controlled by such party or by any one or more of such
subsidiaries.

          AHS represents and warrants to GE Medical that, with respect to itself
and each of its subsidiaries, the statements contained in this ARTICLE 3 are
correct and complete as of the date of this Agreement and will be correct and
complete as of the Closing Date (as though made then and as though the Closing
Date were substituted for the date of this Agreement throughout this ARTICLE 3),
except as set forth in AHS' disclosure schedule attached hereto as ANNEX I (the
"AHS DISCLOSURE SCHEDULE").  Nothing in the AHS Disclosure Schedule shall be
deemed adequate to disclose an exception to a specific representation or
warranty made herein, however, unless such exception is identified to the
specific representation and warranty to which such exception applies (and not
generally to all representations and warranties) in paragraphs corresponding to
the lettered and numbered Sections contained in this ARTICLE 3.  Without
limiting the generality of the foregoing, the mere listing (or inclusion of a
copy) of a document or other item shall not be deemed adequate to disclose an
exception to a representation or warranty made herein (unless the representation
or warranty has to do with the existence of the document or other item
itself).  

          In accordance therewith, AHS represents and warrants to GE Medical,
with respect to itself and its subsidiaries, as follows:

          3.1  ORGANIZATION.  Each of AHS and its subsidiaries (a) is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, (b) has the power to carry on its business as it
is now being conducted or presently proposed to be conducted and (c) is duly
qualified to do business, and is in good standing, in each jurisdiction where
the character of its properties owned or held under lease or the nature of its
activities makes such qualification necessary, except where the failure to be so
qualified will not have a Material Adverse Effect.

          3.2  CAPITALIZATION.  As of the date hereof, the authorized capital
stock of AHS consists of (a) 25,000,000 shares of common stock, par value $0.03
per share, of which 9,713,647 shares are issued and outstanding, and (b)
5,000,000 shares of preferred stock, par value $0.03 per share, of which
37,837.83 shares (designated as Series B Preferred Stock) are issued and
outstanding.  All of the issued and outstanding shares of capital stock of AHS
are validly issued, fully paid and nonassessable and free of preemptive rights
or similar rights created by statute, the Certificate of Incorporation or Bylaws
of AHS, or any agreement by which AHS or any of its subsidiaries is a party or
to which AHS or any of its subsidiaries is bound.   AHS has reserved 1,035,000
shares of its common stock for issuance to directors, employees and consultants
or other persons under stock plans or arrangements, of which 1,015,000 shares
are subject to outstanding options as of the date hereof.  Except as provided in
this SECTION 3.2, there are not any (a) shares of capital stock of AHS issued or
outstanding or any options, warrants, subscriptions, calls, rights, convertible
securities or other agreements or commitments obligating AHS to issue, transfer
or sell any shares of its capital stock or (b) issued and outstanding bonds,
debentures, notes or other indebtedness having the right to vote (or convertible
into or exercisable for securities having the right to vote) on any matters on
which stockholders of AHS may vote.


          3.3  AUTHORITY RELATIVE TO THIS AGREEMENT.  AHS has the corporate
power and authority to enter into this Agreement and to carry out its
obligations hereunder.  The execution and delivery of this Agreement by AHS and
the consummation by AHS of the transactions contemplated by this Agreement, the
Debt Restructuring, the Debt Restructuring Agreements, the Merger and the Merger
Agreement have been duly authorized by the Board of Directors of AHS, and,
except for approval by the requisite votes cast by the stockholders of AHS with
respect to the Merger, no other corporate proceedings on the part of AHS are
necessary to approve this Agreement, the Debt Restructuring, the Debt
Restructuring Agreements, the Merger or the Merger Agreement, or the
transactions contemplated hereby and thereby.

          3.4  VALIDITY.  This Agreement has been duly executed and delivered by
AHS and is the legal, valid and binding obligation of AHS, enforceable in
accordance with its terms.

          3.5  CONSENTS AND APPROVALS; NO VIOLATIONS.  Except for applicable
requirements of the Securities Act of 1933, as amended (the "SECURITIES ACT"),
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT"), or state
securities or blue sky laws, no filing with, and no permit, authorization,
consent or approval of, any governmental body or authority is necessary for the
consummation by AHS of the transactions contemplated by this Agreement, the Debt
Restructuring, the Debt Restructuring Agreements, the Merger or the Merger
Agreement, or the transactions contemplated hereby and thereby.  Neither the
execution and delivery of this Agreement by AHS nor the consummation by AHS of
this Agreement, the Debt Restructuring, the Debt Restructuring Agreements, the
Merger or the Merger Agreement, or the transactions contemplated hereby and
thereby will (a) result in any breach of the Certificate of Incorporation or
Bylaws of AHS, (b) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, cancellation or acceleration) under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, agreement or other instrument or obligation to which AHS or any of its
subsidiaries is a party or by which any of them or any of their properties or
assets may be bound, except as would not have a Material Adverse Effect, or (c)
violate any order, writ, injunction, decree, statute, rule or regulation
applicable to AHS, any of its subsidiaries or any of their properties or assets,
except for violations, breaches or defaults that would not have a Material
Adverse Effect.

          3.6  REPORTS AND FINANCIAL STATEMENTS.  Since January 1, 1994, AHS has
filed all reports required to be filed by it with the Securities and Exchange
Commission (the "SEC") pursuant to the Exchange Act, including, without
limitation, an Annual Report on Form 10-K for the year ended December 31, 1994
(collectively and as amended through the Closing Date, the "AHS SEC REPORTS"),
and has previously furnished or made available to GE Medical true and complete
copies of all of the AHS SEC Reports.  None of the AHS SEC Reports, as of their
respective dates, contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  Each of the balance sheets (including the related notes)
included in the AHS SEC Reports fairly presents in all material respects the
consolidated financial position of AHS and its subsidiaries as of the respective
dates thereof, and the other related statements (including the related notes)
included therein fairly present in all material respects the results of
operations and cash flows of AHS and its subsidiaries for the respective periods
or as of the respective dates set forth therein, all in conformity with
generally accepted accounting principles ("GAAP"), except as otherwise noted
therein and subject, in the case of the unaudited interim financial statements,
to normal year-end adjustments and any other adjustments described therein and
the absence of any notes thereto.

          3.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since December 31, 1994,
neither AHS nor any of its subsidiaries has: 

               (a)  Taken any of the actions set forth in clauses (E) through
     (O) of SECTION 9.1;

               (b)  Incurred any liability material to AHS and its subsidiaries
     on a consolidated basis, except in the ordinary course of its business,
     consistent with past practices;

               (c)  Suffered a Material Adverse Effect; or 

               (d)  Conducted its business and operations other than in the
     ordinary course of business and consistent with past practices.

          3.8  INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION STATEMENT. 
None of the information to be supplied by AHS to be included in (a) the
Registration Statement on Form S-4 to be filed with the SEC by InSight under the
Securities Act for the purpose of registering the common stock of InSight (and,
if required, the InSight Preferred Shares) to be issued in connection with the
consummation of the Merger (the "REGISTRATION STATEMENT") and (b) the joint
proxy statement to be distributed in connection with the meetings of
stockholders of AHS and Maxum to vote upon the Merger (the "PROXY STATEMENT"),
will:

               (a)  in the case of the Registration Statement, at the time it
     becomes effective and at the Closing, 

               (b)  in the case of the Proxy Statement or any amendments thereof
     or supplements thereto, at the time of the mailing of the Proxy Statement
     and any amendments or supplements thereto, and 

               (c)  in either case, at the time of the meeting of stockholders
     of AHS to be held in connection with the Merger, 

contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.  The Registration Statement will comply as to form in all material
respects with the provisions of the Securities Act and the rules and regulations
promulgated thereunder.  The Proxy Statement will comply as to form in all
material respects with the provisions of the Exchange Act and the rules and
regulations promulgated thereunder.

          3.9  LITIGATION.  Except as, in the aggregate, would not reasonably be
expected to have a Material Adverse Effect: 

               (a)  There is no action, suit, judicial or administrative
     proceeding, arbitration or investigation pending or, to the knowledge of
     AHS, threatened against or involving AHS or any of its subsidiaries, or any
     of their properties or rights, before any court, arbitrator, or
     administrative or governmental body; 

               (b)  There is no judgment, decree, injunction, rule or order of
     any court, governmental department, commission, agency or instrumentality,
     or arbitrator outstanding against AHS or any of its subsidiaries; and 

               (c)  Neither AHS not its subsidiaries are in violation of any
     term of any judgments, decrees, injunctions or orders outstanding against
     them.

               (d)  Included in the AHS Disclosure Schedule is a true and
     complete description of all litigation, actions, suits, judicial and
     administrative proceedings, arbitrations, investigations (as to which AHS
     is aware), judgments, decrees, injunctions and orders pending or, to the
     knowledge of AHS, threatened against or involving AHS or any of its
     subsidiaries, or any of their respective properties or rights.

          3.10 CONTRACTS.     (a)  Each of the contracts, instruments,
mortgages, notes, security agreements, leases, agreements and understandings,
whether written or oral, to which AHS or any of its subsidiaries is a party or
that relates to or affects the assets or operations of AHS or any of its
subsidiaries or to which AHS or any of its subsidiaries, or their respective
assets or operations may be bound or subject, is a valid and binding obligation
of AHS and in full force and effect (with respect to AHS or such subsidiary) in
accordance with its terms, except for where the failure to be in full force and
effect could not, in the aggregate, have a Material Adverse Effect.  There are
no existing defaults by AHS or any of its subsidiaries thereunder or, to the
knowledge of AHS, by any other party thereto, which defaults, in the aggregate,
would have a Material Adverse Effect; and, no event of default has occurred, and
no event, condition or occurrence exists, that (whether with or without notice,
lapse of time or the happening or occurrence of any other event) would
constitute a default by AHS or any of its subsidiaries thereunder which default
would, in the aggregate, have a Material Adverse Effect.

               (b)  Except for this Agreement, neither AHS nor any of its
subsidiaries is a party to any oral or written (i) consulting agreement with an
individual not terminable on less than 60 calendar days notice and involving the
payment of more than $50,000 per annum, (ii) joint venture agreement, (iii) non-
competition or similar agreement that restricts AHS or any of its subsidiaries
from engaging in one or more specified lines of business, except for agreements
entered into in the ordinary course of business which could not have a Material
Adverse Effect, (iv) agreement with any executive officer or other employee of
AHS, or any of its subsidiaries, the benefits of which are contingent upon, or
the terms of which may be materially altered by, the occurrence of a transaction
involving AHS of the nature contemplated by this Agreement, the Debt
Restructuring, the Debt Restructuring Agreements, the Merger or the Merger
Agreement, or the transactions contemplated hereby and thereby, and which
provides for the payment of in excess of $50,000, (v) agreement with respect to
any executive officer of AHS or any of its subsidiaries providing any term of
employment beyond one year or compensation guaranty in excess of $50,000 per
annum or (vi) agreement or plan, including any stock option plan, stock
appreciation rights plan, restricted stock plan or stock purchase plan, any of
the benefits of which will be increased, or the vesting of the benefits of which
will be accelerated, by the occurrence of any of the transactions contemplated
by this Agreement, the Debt Restructuring, the Debt Restructuring Agreements,
the Merger or the Merger Agreement, or the value of any of the benefits of which
will be calculated on the basis of any of the transactions contemplated by this
Agreement, the Debt Restructuring, the Debt Restructuring Agreements, the Merger
or the Merger Agreement.

          3.11 EMPLOYEE BENEFIT PLANS.  (a)  Included in the AHS Disclosure
Schedule is a true and complete list of each written or formal employee benefit
plan (including, without limitation, any "employee benefit plan" as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")), policy or agreement that is maintained by AHS or any of its
subsidiaries (all of the foregoing, the "AHS BENEFIT PLANS"), or is or was
contributed to by AHS or pursuant to which AHS (or any trade or business,
whether or not incorporated (an "AHS ERISA AFFILIATE"), which together with AHS
would be deemed a "single employer" within the meaning of Section 4001 of ERISA)
is still potentially liable for payments, benefits or claims.  A copy of each
AHS Benefit Plan as currently in effect and, if applicable, the most recent
Annual Report, Actuarial Report or Valuation, Summary Plan Description, Trust
Agreement and a Determination Letter issued by the IRS for each AHS Benefit Plan
have heretofore been delivered to GE Medical.  No AHS Benefit Plan (including
any "multiemployer plan," as defined in Section 3(37) of ERISA) was or is
subject to Title IV of ERISA or Section 412 of the Internal Revenue Code of
1986, as amended (the "CODE").

               (b)  Each of the AHS Benefit Plans that is subject to ERISA is in
substantial compliance with ERISA.  Each of the AHS Benefit Plans intended to be
"qualified" within the meaning of Section 401(a) of the Code is so qualified. 
No event has occurred, and to the knowledge of AHS, no condition or set of
circumstances exists, in connection with which AHS or any AHS ERISA Affiliate is
or could be subject to liability (except liability for benefit claims and
funding obligations payable in the ordinary course of business) under ERISA, the
Code or any other applicable law with respect to any AHS Benefit Plan.

               (c)  All contributions and other amounts payable by AHS or any of
its subsidiaries through September 30, 1995, with respect to each AHS Benefit
Plan in respect of current or prior plan years have been either paid or accrued
on the most recent financial statements of AHS.  Any contributions or other
amounts payable by AHS or any of its subsidiaries for periods between September
30, 1995, and the Closing with respect to each AHS Benefit Plan in respect of
current or prior plan years have been or will be either paid or accrued in the
normal course of business on the books and records of AHS at or prior to the
Closing.  There are no pending, or, to the knowledge of AHS, threatened or
anticipated claims (other than routine claims for benefits which will not, in
the aggregate, have a Material Adverse Effect) by or on behalf of or against any
of the AHS Benefit Plans or any trusts or other funding vehicles related
thereto.

               (d)  No AHS Benefit Plan (other than general employment policies
and agreements) provides benefits, including without limitation, death or
medical benefits (whether or not insured), with respect to current or former
employees for periods extending beyond their retirement or other termination of
service (other than (i) coverage mandated by Part 6 of Subtitle B of Title I of
ERISA, Section 4980B of the Code or any comparable state law, (ii) death
benefits or retirement benefits under any "employee pension plan," as that term
is defined in Section 3(2) of ERISA, (iii) deferred compensation benefits
accrued as liabilities on the books of AHS or the AHS ERISA Affiliates, or (iv)
benefits the full cost of which is borne by the current or former employee or
his or her beneficiary).

          3.12 TAXES.  For the purposes of this SECTION 3.12, the term "TAX"
shall include all taxes, charges, withholdings, fees, levies, penalties,
additions, interest or other assessments imposed by any United States federal,
state or local authority or any other taxing authority on AHS or any of the AHS
Tax Affiliates (as defined in this SECTION 3.12) as to their respective income,
profit, franchise, gross receipts, payroll, sales, employment, worker's
compensation, use, property, withholding, excise, occupancy, environmental, and
other taxes, duties or assessments of any nature whatsoever.  AHS has filed or
caused to be filed timely all material federal, state, local and foreign tax
returns required to be filed by AHS and any member of its consolidated,
combined, unitary or similar group (each such member, an "AHS TAX AFFILIATE"). 
Such returns, reports and other information are accurate and complete in all
material respects.  AHS has paid or caused to be paid, or has made adequate
provision or set up an adequate accrual or reserve for the payment of, all taxes
shown to be due in respect of the periods for which returns are due, and has
established an adequate accrual or reserve for the payment of all taxes payable
in respect of the period subsequent to the last of such periods in respect of
which any such accrual or reserve is required.  Neither AHS nor any of the AHS
Tax Affiliates has any material liability for taxes in excess of the amount so
paid or accruals or reserves so established.  Neither AHS nor any of the AHS Tax
Affiliates is delinquent in the payment of any tax in excess of the amount
reserved or provided therefor, and no deficiencies for any tax, assessment or
governmental charge in excess of the amount reserved or provided therefor have
been threatened, claimed, proposed or assessed.  No waiver or extension of time
to assess any taxes has been given or requested.

          3.13 COMPLIANCE WITH APPLICABLE LAW.  AHS and each of its subsidiaries
holds all licenses, franchises, permits, variances, exemptions, orders,
approvals and authorizations necessary for the lawful conduct of its business
under and pursuant to, and the business of AHS and its subsidiaries is not being
conducted in violation of, any provision of any federal, state, local or foreign
statute, law, ordinance, rule, regulation, judgment, decree, order, concession,
grant, franchise, permit or license or other governmental authorization or
approval applicable to AHS or any of its subsidiaries, except to the extent that
the failure to hold any such licenses, franchises, permits or authorizations, or
any such violation, would not, in the aggregate, have a Material Adverse Effect.

          3.14 SUBSIDIARIES.  Exhibit 22.1 to the most recent Form 10-K included
in the AHS SEC Reports lists all the subsidiaries of AHS and indicates for each
subsidiary of AHS as of such date the jurisdiction of incorporation or
organization thereof.  All of the outstanding shares of capital stock or other
equity interests of each of the subsidiaries of AHS are (a) held by AHS or one
of its wholly-owned subsidiaries, (b) fully paid and nonassessable, and (c)
owned by AHS or one of its wholly-owned subsidiaries free and clear of any
claim, lien or encumbrance.

          3.15 LABOR AND EMPLOYMENT MATTERS.  AHS and each of its subsidiaries
(a) are and have been in compliance in all material respects with all applicable
laws respecting employment and employment practices and terms and conditions of
employment and wages and hours (including, without limitation, the Immigration
Reform and Control Act, the Worker Adjustment and Retraining Notification Act
and such laws respecting employment discrimination, equal opportunity,
affirmative action, worker's compensation, occupational safety and health
requirements and unemployment insurance and related matters) and (b) are not
engaged in and have not engaged in any unfair labor practice.  No investigation
or review by or before any governmental entity concerning any violation of any
such law is pending or, to the knowledge of AHS, threatened or has occurred
during the last three years, and no governmental entity has provided any notice
to AHS or any of its subsidiaries or otherwise asserted an intention to conduct
any such investigation.  There is no labor strike, dispute, slowdown or stoppage
actually pending or threatened against AHS or any of its subsidiaries.  No union
representation question or union organizational activity exists respecting the
employees of AHS or any of its subsidiaries.  No collective bargaining agreement
exists which is binding on AHS or any of its subsidiaries.  Neither AHS nor any
of its subsidiaries has experienced any material work stoppage or other material
labor difficulty.  In the event of termination of the employment of any of the
current officers, directors, employees or agents of AHS or any of its
subsidiaries, neither AHS nor any of its subsidiaries will, pursuant to any
agreement or by reason of anything done prior to the Closing be liable to any of
such officers, directors, employees or agents for so-called "severance pay" or
any other similar payments or benefits, including, without limitation, post-
employment health care benefits (other than pursuant to the Consolidated Omnibus
Budget Reconciliation Act of 1985 ("COBRA")) or insurance benefits.

          3.16 INSURANCE.  AHS and each of its subsidiaries are insured by
insurers reasonably believed by AHS to be of recognized financial responsibility
against such losses and risks and in such amounts as are customary in the
businesses in which they are engaged.  All material policies of insurance and
fidelity or surety bonds insuring AHS or any of its subsidiaries or their
respective businesses, assets, employees, officers and directors are in full
force and effect.  There are no material claims by AHS or any of its
subsidiaries under any such policy or instrument as to which any insurance
company is denying liability or defending under a reservation of rights clause.

          3.17 CONTRACTS WITH PHYSICIANS, HOSPITALS, HMOS AND THIRD PARTY
PROVIDERS.  AHS has made available to representatives of GE Medical copies (or
in the case where no written documentation exists, a summary) of all outstanding
contracts, partnerships, joint ventures and other arrangements or understandings
(written or oral) between (a) AHS or any of its subsidiaries and (b) any
physician, hospital, health maintenance organization or other managed care
organization, or other third-party provider relating to the provision of medical
or consulting services, treatments, patient referrals or similar activities.

          3.18 ABSENCE OF UNDISCLOSED LIABILITIES.  Neither AHS nor any of its
subsidiaries is obligated under or subject to any indebtedness, duty,
responsibility, liability or obligation of any nature, whether absolute,
accrued, contingent or otherwise, other than (a) in the ordinary course of
business on terms and conditions and in amounts consistent with past practices
of AHS and in no event on terms atypical to those of other companies in the same
or a similar industry or (b) as disclosed in the financial statements included
in the AHS SEC Reports. 

          3.19 ENVIRONMENTAL MATTERS.  Except as could not have a Material
Adverse Effect, the ownership, use and operation by AHS and its subsidiaries,
and each of their predecessors, of each facility used by AHS in the operation of
its business has been and is in compliance with all federal, state and local
environmental and anti-pollution laws and regulations, including (a) the
Resource Conservation and Recovery Act, as amended, and its implementing
regulations and all applicable state hazardous waste laws and regulations, (b)
the Clean Water Act, as amended, and its implementing regulations and all
applicable state effluent discharge laws and regulations, (c) the Clean Air Act,
as amended, and its implementing regulations and all applicable state air
emission laws and regulations and (d) all such laws and regulations concerning
particulate emissions, hazard communication, surface water pollution,
groundwater pollution, air pollution, solid wastes, hazardous wastes, storage,
handling, treatment, transportation, spills or other releases, or disposal of
any substance, material or waste, or exposure to or notification regarding any
substance, material or waste.  No action, suit, proceeding, investigation,
complaint or charge exists for violation of any such laws, rules or regulations
and there is no meritorious basis therefor. 

          3.20 DISCLOSURE.  The representations and warranties of AHS contained
in this Agreement and each certificate or other written statement delivered pur-
suant to this Agreement, the Debt Restructuring, the Debt Restructuring
Agreements, the Merger or the Merger Agreement and the transactions contemplated
hereby and thereby, are accurate, correct and complete, do not contain any
untrue statement of a material fact or, considered in the context in which
presented, omit to state a material fact necessary in order to make the
statements and information contained herein or therein not misleading.  AHS is
not aware of any material information necessary to enable GE Medical to make an
informed investment decision to purchase the AHS Shares which has not been
expressly disclosed to GE Medical in writing.  There is no fact which would
have, or in the future may have (so far as AHS can now foresee), a Material
Adverse Effect which has not been set forth or described in this Agreement or in
a certificate, exhibit or other written statement furnished to GE Medical in
connection herewith.


                                    ARTICLE 4
                 REPRESENTATIONS AND WARRANTIES REGARDING MAXUM

          Maxum represents and warrants to GE Medical that, with respect to
itself and each of its subsidiaries, the statements contained in this ARTICLE 4
are correct and complete as of the date of this Agreement and will be correct
and complete as of the Closing Date (as though made then and as though the
Closing Date were substituted for the date of this Agreement throughout this
ARTICLE 4), except as set forth in Maxum's disclosure schedule attached hereto
as ANNEX II (the "MAXUM DISCLOSURE SCHEDULE").  Nothing in the Maxum Disclosure
Schedule shall be deemed adequate to disclose an exception to a specific
representation or warranty made herein, however, unless such exception is
identified to the specific representation and warranty to which such exception
applies (and not generally to all representations and warranties) in paragraphs
corresponding to the lettered and numbered Sections contained in this ARTICLE
4.  Without limiting the generality of the foregoing, the mere listing (or
inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made
herein (unless the representation or warranty has to do with the existence
of the document or other item itself).    

          In accordance therewith, Maxum represents and warrants to GE Medical,
with respect to itself and its subsidiaries, as follows:

          4.1  ORGANIZATION.  Each of Maxum and its subsidiaries (a) is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, (b) has the power to carry on its business as it
is now being conducted or presently proposed to be conducted and (c) is duly
qualified to do business, and is in good standing, in each jurisdiction where
the character of its properties owned or held under lease or the nature of its
activities makes such qualification necessary, except where the failure to be so
qualified will not have a Material Adverse Effect.

          4.2  CAPITALIZATION.  As of the date hereof, the authorized capital
stock of Maxum consists of (a) 10,000,000 shares of common stock, par value
$0.01 per share, 2,273,555 shares of which are issued and outstanding, and (b)
56,000 shares of preferred stock, par value $0.01 per share, none of which are
issued and outstanding.  All of the issued and outstanding shares of capital
stock of Maxum are validly issued, fully paid and nonassessable and free of
preemptive rights or similar rights created by statute, the Certificate of
Incorporation or Bylaws of Maxum, or any agreement by which Maxum or any of its
subsidiaries is a party or to which Maxum or any of its subsidiaries is bound. 
Maxum has reserved 1,037,500 shares of its common stock for issuance to
directors, employees and consultants or other persons under stock plans or
arrangements, of which 416,250 shares are subject to outstanding options as of
the date hereof.  Except as provided in this SECTION 4.2, there are not any (a)
shares of capital stock of Maxum issued or outstanding or any options, warrants,
subscriptions, calls, rights, convertible securities or other agreements or
commitments obligating Maxum to issue, transfer or sell any shares of its
capital stock or (b) issued and outstanding bonds, debentures, notes or other
indebtedness having the right to vote (or convertible into or exercisable for
securities having the right to vote) on any matters on which stockholders of
Maxum may vote.

          4.3  AUTHORITY RELATIVE TO THIS AGREEMENT.  Maxum has the corporate
power and authority to enter into this Agreement and to carry out its
obligations hereunder.  The execution and delivery of this Agreement by Maxum
and the consummation by Maxum of the transactions contemplated by this
Agreement, the Debt Restructuring, the Debt Restructuring Agreements, the Merger
and the Merger Agreement have been duly authorized by the Board of Directors of
Maxum, and, except for approval by the requisite votes cast by the stockholders
of Maxum with respect to the Merger, no other corporate proceedings on the part
of Maxum are necessary to approve this Agreement, the Debt Restructuring, the
Debt Restructuring Agreements, the Merger or the Merger Agreement, or the
transactions contemplated hereby and thereby.

          4.4  VALIDITY.  This Agreement has been duly executed and delivered by
Maxum and is the legal, valid and binding obligation of Maxum, enforceable in
accordance with its terms.

          4.5  CONSENTS AND APPROVALS; NO VIOLATIONS.  Except for applicable
requirements of the Securities Act, the Exchange Act, or state securities or
blue sky laws, no filing with, and no permit, authorization, consent or approval
of, any governmental body or authority is necessary for the consummation by
Maxum of the transactions contemplated by this Agreement, the Debt
Restructuring, the Debt Restructuring Agreements, the Merger or the Merger
Agreement, or the transactions contemplated hereby and thereby.  Neither the
execution and delivery of this Agreement by Maxum nor the consummation by Maxum
of this Agreement, the Debt Restructuring, the Debt Restructuring Agreements,
the Merger or the Merger Agreement, or the transactions contemplated hereby and
thereby will (a) result in any breach of the Certificate of Incorporation or
Bylaws of Maxum, (b) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, cancellation or acceleration) under, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, agreement or other instrument or obligation to which Maxum or any of
its subsidiaries is a party or by which any of them or any of their properties
or assets may be bound, except as would not have a Material Adverse Effect, or
(c) violate any order, writ, injunction, decree, statute, rule or regulation
applicable to Maxum, any of its subsidiaries or any of their properties or
assets, except for violations, breaches or defaults that would not have a
Material Adverse Effect.

          4.6  REPORTS AND FINANCIAL STATEMENTS.  Since January 1, 1994, Maxum
has filed all reports required to be filed by it with the SEC pursuant to the
Exchange Act, including, without limitation, an Annual Report on Form 10-K for
the year ended December 31, 1994 (collectively and as amended through the
Closing Date, the "MAXUM SEC REPORTS"), and has previously furnished or made
available to GE Medical true and complete copies of all of the Maxum SEC
Reports.  None of the Maxum SEC Reports, as of their respective dates, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.  Each of
the balance sheets (including the related notes) included in the Maxum SEC
Reports fairly presents in all material respects the consolidated financial
position of Maxum and its subsidiaries as of the respective dates thereof, and
the other related statements (including the related notes) included therein
fairly present in all material respects the results of operations and cash flows
of Maxum and its subsidiaries for the respective periods or as of the respective
dates set forth therein, all in conformity with GAAP, except as otherwise noted
therein and subject, in the case of the unaudited interim financial statements,
to normal year-end adjustments and any other adjustments described therein and
the absence of any notes thereto.

          4.7  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since December 31, 1994,
neither Maxum nor any of its subsidiaries has:

               (a)  Taken any of the actions set forth in clauses (E) through
     (O) of SECTION 9.1;

               (b)  Incurred any liability material to Maxum and its
     subsidiaries on a consolidated basis, except in the ordinary course of its
     business, consistent with past practices;

               (c)  Suffered a Material Adverse Effect; or 

               (d)  Conducted its business and operations other than in the
     ordinary course of business and consistent with past practices.

          4.8  INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION STATEMENT. 
None of the information to be supplied by Maxum to be included in the
Registration Statement and the Proxy Statement, will:

               (a)  in the case of the Registration Statement, at the time it
     becomes effective and at the Closing, 

               (b)  in the case of the Proxy Statement or any amendments thereof
     or supplements thereto, at the time of the mailing of the Proxy Statement
     and any amendments or supplements thereto, and 

               (c)  in either case, at the time of the meeting of stockholders
     of Maxum to be held in connection with the Merger, 

contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.  The Registration Statement will comply as to form in all material
respects with the provisions of the Securities Act, and the rules and
regulations promulgated thereunder.  The Proxy Statement will comply as to form
in all material respects with the provisions of the Exchange Act and the rules
and regulations promulgated thereunder.

          4.9  LITIGATION.  Except as, in the aggregate, would not reasonably be
expected to have a Material Adverse Effect: 

               (a)  There is no action, suit, judicial or administrative
     proceeding, arbitration or investigation pending or, to the knowledge of
     Maxum, threatened against or involving Maxum or any of its subsidiaries, or
     any of their properties or rights, before any court, arbitrator, or
     administrative or governmental body; 

               (b)  There is no judgment, decree, injunction, rule or order of
     any court, governmental department, commission, agency or instrumentality,
     or arbitrator outstanding against Maxum or any of its subsidiaries; and 

               (c)  Neither Maxum not its subsidiaries are in violation of any
     term of any judgments, decrees, injunctions or orders outstanding against
     them.

               (d)  Included in the Maxum Disclosure Schedule is a true and
     complete description of all litigation, actions, suits, judicial and
     administrative proceedings, arbitrations, investigations (as to which Maxum
     is aware), judgments, decrees, injunctions and orders pending, or, to the
     knowledge of Maxum, threatened against or involving Maxum or any of its
     subsidiaries, or any of their respective properties or rights.

          4.10 CONTRACTS.

               (a)  Each of the contracts, instruments, mortgages, notes,
security agreements, leases, agreements and understandings, whether written or
oral, to which Maxum or any of its subsidiaries is a party or that relates to or
affects the assets or operations of Maxum or any of its subsidiaries or to which
Maxum or any of its subsidiaries or their respective assets or operations may be
bound or subject, is a valid and binding obligation of Maxum and in full force
and effect (with respect to Maxum or such subsidiary) in accordance with its
terms, except for where the failure to be in full force and effect could not, in
the aggregate, have a Material Adverse Effect.  There are no existing defaults
by Maxum or any of its subsidiaries thereunder or, to the knowledge of Maxum, by
any other party thereto, which defaults, in the aggregate, would have a Material
Adverse Effect; and, no event of default has occurred, and no event, condition
or occurrence exists, that (whether with or without notice, lapse of time or the
happening or occurrence of any other event) would constitute a default by Maxum
or any of its subsidiaries thereunder which default would, in the aggregate,
have a Material Adverse Effect.

               (b)  Except for this Agreement, neither Maxum nor any of its
subsidiaries is a party to any oral or written (i) consulting agreement with an
individual not terminable on 60 calendar days or less notice involving the
payment of more than $50,000 per annum, in the case of any such agreement, (ii)
joint venture agreement, (iii) non-competition or similar agreement that
restricts Maxum or its subsidiaries from engaging in a line of business, except
for agreements entered into in the ordinary course of business which could not
have a Material Adverse Effect, (iv) agreement with any executive officer or
other employee of Maxum, or any of its subsidiaries, the benefits of which are
contingent upon, or the terms of which are materially altered by, the occurrence
of a transaction involving Maxum of the nature contemplated by this Agreement,
the Debt Restructuring, the Debt Restructuring Agreements, the Merger or the
Merger Agreement, or the transactions contemplated hereby and thereby, and which
provides for the payment of in excess of $50,000, (v) agreement with respect to
any executive officer of Maxum or any of its subsidiaries providing any term of
employment beyond one year or compensation guaranty in excess of $50,000 per
annum, or (vi) agreement or plan, including any stock option plan, stock
appreciation rights plan, restricted stock plan or stock purchase plan, any of
the benefits of which will be increased, or the vesting of the benefits of which
will be accelerated, by the occurrence of any of the transactions contemplated
by this Agreement, the Debt Restructuring, the Debt Restructuring Agreements,
the Merger or the Merger Agreement, or the value of any of the benefits of which
will be calculated on the basis of any of the transactions contemplated by this
Agreement, the Debt Restructuring, the Debt Restructuring Agreements, the Merger
or the Merger Agreement.

          4.11 EMPLOYEE BENEFIT PLANS.

               (a)  Included in the Maxum Disclosure Schedule is a true and
complete list of each written or formal employee benefit plan (including,
without limitation, any "employee benefit plan" as defined in Section 3(3) of
ERISA), policy or agreement that is maintained by Maxum or any of its
subsidiaries (all of the foregoing, the "MAXUM BENEFIT PLANS"), or is or was
contributed to by Maxum or pursuant to which Maxum (or any trade or business,
whether or not incorporated (a "MAXUM ERISA AFFILIATE"), which together with
Maxum would be deemed a "single employer" within the meaning of Section 4001 of
ERISA) is still potentially liable for payments, benefits or claims.  A copy of
each Maxum Benefit Plan as currently in effect and, if applicable, the most
recent Annual Report, Actuarial Report or Valuation, Summary Plan Description,
Trust Agreement and a Determination Letter issued by the IRS for each Maxum
Benefit Plan have heretofore been delivered to GE Medical.  No Maxum Benefit
Plan (including any "multiemployer plan," as defined in Section 3(37) of ERISA)
was or is subject to Title IV of ERISA or Section 412 of the Code.

               (b)  Each of the Maxum Benefit Plans that is subject to ERISA is
in substantial compliance with ERISA.  Each of the Maxum Benefit Plans intended
to be "qualified" within the meaning of Section 401(a) of the Code is so
qualified.  No event has occurred, and to the knowledge of Maxum, no condition
or set of circumstances exists, in connection with which Maxum or any Maxum
ERISA Affiliate is or could be subject to liability (except liability for
benefit claims and funding obligations payable in the ordinary course of
business) under ERISA, the Code or any other applicable law with respect to any
Maxum Benefit Plan.

               (c)  All contributions and other amounts payable by Maxum or any
of its subsidiaries through September 30, 1995, with respect to each Maxum
Benefit Plan in respect of current or prior plan years have been either paid or
accrued on the most recent financial statements of Maxum.  Any contributions or
other amounts payable by Maxum or any of its subsidiaries for periods between
September 30, 1995, and the Closing with respect to each Maxum Benefit Plan in
respect of current or prior plan years have been or will be either paid or
accrued in the normal course of business on the books and records of Maxum at or
prior to the Closing.  There are no pending, or, to the knowledge of Maxum,
threatened or anticipated claims (other than routine claims for benefits which
will not, in the aggregate, have a Material Adverse Effect) by or on behalf of
or against any of the Maxum Benefit Plans or any trusts or other funding
vehicles related thereto.

               (d)  No Maxum Benefit Plan (other than general employment
policies and agreements) provides benefits, including without limitation, death
or medical benefits (whether or not insured), with respect to current or former
employees for periods extending beyond their retirement or other termination of
service (other than (i) coverage mandated by Part 6 of Subtitle B of Title I of
ERISA, Section 4980B of the Code or any comparable state law, (ii) death
benefits or retirement benefits under any "employee pension plan," as that term
is defined in Section 3(2) of ERISA, (iii) deferred compensation benefits
accrued as liabilities on the books of Maxum or the Maxum ERISA Affiliates, or
(iv) benefits the full cost of which is borne by the current or former employee
or his or her beneficiary).

          4.12  TAXES.  For the purposes of this SECTION 4.12, the term "TAX"
shall include all taxes, charges, withholdings, fees, levies, penalties,
additions, interest or other assessments imposed by any United States federal,
state or local authority or any other taxing authority on Maxum or any of the
Maxum Tax Affiliates (as defined in this SECTION 4.12) as to their respective
income, profit, franchise, gross receipts, payroll, sales, employment, worker's
compensation, use, property, withholding, excise, occupancy, environmental, and
other taxes, duties or assessments of any nature whatsoever.  Maxum has filed or
caused to be filed timely all material federal, state, local and foreign tax
returns required to be filed by Maxum and any member of its consolidated,
combined, unitary or similar group (each such member, a "MAXUM TAX AFFILIATE"). 
Such returns, reports and other information are accurate and complete in all
material respects.  Maxum has paid or caused to be paid or has made adequate
provision or set up an adequate accrual or reserve for the payment of, all taxes
shown to be due in respect of the periods for which returns are due, and has
established an adequate accrual or reserve for the payment of all taxes payable
in respect of the period subsequent to the last of such periods in respect of
which any such accrual or reserve is required.  Neither Maxum nor any of the
Maxum Tax Affiliates has any material liability for taxes in excess of the
amount so paid or accruals or reserves so established.  Neither Maxum nor any of
the Maxum Tax Affiliates is delinquent in the payment of any tax in excess of
the amount reserved or provided therefor, and no deficiencies for any tax,
assessment or governmental charge in excess of the amount reserved or provided
therefor have been threatened, claimed, proposed or assessed.  No waiver or
extension of time to assess any taxes has been given or requested.

          4.13  COMPLIANCE WITH APPLICABLE LAW.  Maxum and each of its
subsidiaries holds all licenses, franchises, permits, variances, exemptions,
orders, approvals and authorizations necessary for the lawful conduct of its
business under and pursuant to, and the business of Maxum and its subsidiaries
is not being conducted in violation of, any provision of any federal, state,
local or foreign statute, law, ordinance, rule, regulation, judgment, decree,
order, concession, grant, franchise, permit or license or other governmental
authorization or approval applicable to Maxum or any of its subsidiaries, except
to the extent that the failure to hold any such licenses, franchises, permits or
authorizations, or any such violation, would not, in the aggregate, have a
Material Adverse Effect.

          4.14  SUBSIDIARIES.  Exhibit 22.1 to the most recent Form 10-K
included in the Maxum SEC Reports lists all the subsidiaries of Maxum and
indicates for each subsidiary of Maxum as of such date the jurisdiction of
incorporation or organization thereof.  All of the outstanding shares of capital
stock or other equity interests of each of the subsidiaries of Maxum are (a)
held by Maxum or one of its wholly-owned subsidiaries, (b) fully paid and
nonassessable, and (c) owned by Maxum or one of its wholly-owned subsidiaries
free and clear of any claim, lien or encumbrance.

          4.15  LABOR AND EMPLOYMENT MATTERS.  Maxum and its subsidiaries (a)
are and have been in compliance in all material respects with all applicable
laws respecting employment and employment practices, terms and conditions of
employment and wages and hours, including, without limitation, the Immigration
Reform and Control Act, the Worker Adjustment and Retraining Notification Act,
and such laws respecting employment discrimination, equal opportunity,
affirmative action, worker's compensation, occupational safety and health
requirements and unemployment insurance and related matters, and (b) are not
engaged in and have not engaged in any unfair labor practice.  No investigation
or review by or before any governmental entity concerning any violation of any
such law is pending or, to the knowledge of Maxum, threatened, nor has any such
investigation occurred during the last three years, and no governmental entity
has provided any notice to Maxum or any of its subsidiaries or otherwise
asserted an intention to conduct any such investigation.  There is no labor
strike, dispute, slowdown or stoppage actually pending or threatened against
Maxum or any of its subsidiaries.  No union representation question or union
organizational activity exists respecting the employees of Maxum or any of its
subsidiaries.  No collective bargaining agreement exists which is binding on
Maxum or any of its subsidiaries.  Neither Maxum nor any of its subsidiaries has
experienced any material work stoppage or other material labor difficulty.  In
the event of termination of the employment of any of the current officers,
directors, employees or agents of Maxum or any of its subsidiaries, neither
Maxum nor any of its subsidiaries will, pursuant to any agreement or by reason
of anything done prior to the Closing be liable to any of such officers,
directors, employees or agents for so-called "severance pay" or any other
similar payments or benefits, including, without limitation, post-employment
health care benefits (other than pursuant to COBRA) or insurance benefits.

          4.16  INSURANCE.  Maxum and each of its subsidiaries are insured by
insurers reasonably believed by Maxum to be of recognized financial
responsibility against such losses and risks and in such amounts as are
customary in the businesses in which they are engaged.  All material policies of
insurance and fidelity or surety bonds insuring Maxum or any of its subsidiaries
or their respective businesses, assets, employees, officers and directors are in
full force and effect.  There are no material claims by Maxum or any of its
subsidiaries under any such policy or instrument as to which any insurance
company is denying liability or defending under a reservation of rights clause.

          4.17  CONTRACTS WITH PHYSICIANS, HOSPITALS, HMOS AND THIRD PARTY
PROVIDERS.  Maxum has made available to representatives of GE Medical copies (or
in the case where no written documentation exists, a summary) of all outstanding
contracts, partnerships, joint ventures and other arrangements or understandings
(written or oral) between (a) Maxum or any of its subsidiaries and (b) any
physician, hospital, health maintenance organization or other managed care
organization, or other third-party provider relating to the provision of medical
or consulting services, treatments, patient referrals or similar activities.

          4.18  ABSENCE OF UNDISCLOSED LIABILITIES.  Neither Maxum nor any of
its subsidiaries is obligated under or subject to any indebtedness, duty,
responsibility, liability or obligation of any nature, whether absolute,
accrued, contingent or otherwise, other than (a) in the ordinary course of
business on terms and conditions and in amounts consistent with past practices
of Maxum and in no event on terms atypical to those of other companies in the
same or a similar industry or (b) as disclosed in the financial statements
included in the Maxum SEC Reports. 

          4.19  ENVIRONMENTAL MATTERS.  Except as would not have a Material

regulations and all applicable state hazardous waste laws and regulations, (b)
the Clean Water Act, as amended, and its implementing regulations and all
applicable state effluent discharge laws and regulations, (c) the Clean Air Act,
as amended, and its implementing regulations, and (d) all applicable state air

transactions contemplated hereby and thereby, are accurate, correct and

the existence of any such inquiry, proposal, expression of interest or offer and
shall not furnish any information to, or participate in any discussions or
negotiations with, any other person or entity with respect thereto.

          9.3  CONSENTS.  Such InSight Party shall use its best efforts to
obtain all consents (including the consents described on SCHEDULE 7.3) by third
parties that are required for the transfer of the AHS Shares and the Maxum
Shares or otherwise, for the consummation of the transactions contemplated
hereby, or in order to prevent a material breach of or a default under or a
termination of any agreement to which any of the InSight Parties is a party or
to which any portion of the property of the InSight Parties is subject.


                                   ARTICLE 10
                   ADDITIONAL COVENANTS OF THE INSIGHT PARTIES

          Each of the InSight Parties hereby agrees, from and after the date
hereof (including following the Closing), to keep, perform and fully discharge
the following covenants and agreements:

          10.1 ACCESS.  Each of the InSight Parties shall give GE Medical and
its representatives full and free access to all properties, books, contracts,
commitments and records and shall furnish GE Medical with all financial and
operating data and other information regarding their respective businesses and
the properties and assets of the InSight Parties as GE Medical may from time to
time reasonably request.  Each of the InSight Parties shall promptly notify GE
Medical of any change in the normal course of business or prospects of such
InSight Party or its business and shall keep GE Medical fully informed with
respect thereto.

          10.2 ADDITIONAL COVENANTS.  Except for transactions expressly approved
in writing by GE Medical, each of the InSight Parties agrees as follows:

               (a)  Each of the InSight Parties will promptly pay and discharge,
     or cause to be paid and discharged, when due and payable, all lawful taxes,
     assessments and governmental charges and levies imposed upon the income,
     profits, property, or business of such InSight Party or any subsidiary
     thereof; provided, however, that no such tax, assessment, charge or levy
     need be paid by an InSight Party if the validity thereof shall currently be
     contested in good faith by appropriate proceedings and if such InSight
     Party shall have set aside on its books adequate reserves with respect
     thereto (unless such tax, assessment, charge, or levy has given rise to the
     commencement of proceedings to foreclose any lien that may have attached as
     security therefor).  Each of the InSight Parties will promptly pay or cause
     to be paid when due, or in conformance with customary trade terms, all
     other indebtedness incident to the operations of such InSight Party;

               (b)  Each of the InSight Parties will keep its properties in good
     repair, working order and condition, reasonable wear and tear excepted, and
     from time to time make all necessary and proper repairs, renewals,
     replacements, additions and improvements thereto; and, each of the InSight
     Parties will at all times comply with the provisions of all material leases
     to which such InSight Party is a party or under which such InSight Party
     occupies property so as to prevent any loss or forfeiture thereof or
     thereunder;

               (c)  Each of the InSight Parties will keep its assets that are of
     an insurable character insured by financially sound and reputable insurers
     against loss or damage by fire and maintain extended coverage insurance in
     amounts customary for companies in similar businesses and each of the
     InSight Parties will maintain, with financially sound and reputable
     insurers, insurance against other hazards, risks and liabilities to persons
     and property to the extent and in the manner customary for companies in
     similar businesses;

               (d)  Each of the InSight Parties will keep true records and books
     of account in which full, true and correct entries will be made of all
     dealings or transactions relating to its business and affairs in accordance
     with GAAP; 

               (e)  Each of the InSight Parties shall duly observe and conform
     to all valid requirements of governmental authorities relating to the
     conduct of such InSight Party's businesses or to such InSight Party's
     property or assets;

               (f)  Each of the InSight Parties shall maintain in full force and
     effect its corporate existence, rights and franchises and all licenses and
     other rights to use patents, processes, licenses, trademarks, trade names
     and copyrights owned or possessed thereby and deemed to be necessary to the
     conduct of its business;

               (g)  In the event the services of the independent public
     accountants hereafter employed by the InSight Parties are terminated, the
     InSight Parties will (i) promptly thereafter notify GE Medical by letter
     setting forth the reasons for the termination of such services and (ii)
     request the firm of independent public accountants whose services are
     terminated to deliver to GE Medical a letter from such firm setting forth
     the reasons for the termination of their services.  In the event of such
     termination, the InSight Parties will promptly thereafter engage another
     firm of independent public accountants.  In its notice to GE Medical, the
     InSight Parties shall state whether the change of accountants was
     recommended or approved by the InSight Parties' Board of Directors;

               (h)  Each of the InSight Parties will cause each person now or
     hereafter employed thereby in a management position with access to
     confidential information to enter into a proprietary information agreement
     substantially in the form approved by such InSight Party's Board of
     Directors.

          10.3 MAINTENANCE OF SINGLE LOCATION OF PRINCIPAL EXECUTIVE OFFICE. 
Each of the InSight Parties shall use its best efforts to establish and maintain
the principal executive offices and principal administration functions of the
InSight Parties at one location.

          10.4 ADOPTION OF STOCK OPTION GUIDELINES.  InSight shall not, without
first obtaining the approval of GE Medical, establish, adopt or approve (a)
guidelines with respect to the granting and vesting of stock options or shares
issued under the Insight Stock Plans or (b) the specific terms, conditions and
provisions of stock options or shares issued under the Insight Stock Plans which
could result in the issuance of more than 882,434 shares, in the aggregate,
under such Insight Stock Plans.


                                   ARTICLE 11
                            COVENANTS OF ALL PARTIES

          Each party hereto hereby agrees to keep, perform and fully discharge
the following covenants and agreements:

          11.1 CONFIDENTIALITY.  (A) Each party hereto shall treat all
information regarding the other parties hereto obtained in connection with the
negotiation and consummation of the transactions contemplated by this Agreement,
the Debt Restructuring, the Debt Restructuring Agreements, the Merger and the
Merger Agreement as confidential and shall not use any such information in any
manner other than in furtherance of such transactions; provided, however, that
such confidentiality obligation shall not apply to information disclosed or used
by any party (the "DISCLOSING PARTY") with respect to any other party hereto
(the "SUBJECT PARTY") that (i) is or becomes generally available to the public
other than as a result of a disclosure by the Disclosing Party, (ii) was
available to the Disclosing Party on a nonconfidential basis prior to the
disclosure by the Subject Party or (iii) becomes available to the Disclosing
Party on a nonconfidential basis from a person or entity (other than the Subject
Party) which is not otherwise bound by a confidentiality agreement with the
Subject Party.

               (B)  Unless otherwise required by law, none of the parties hereto
shall, without the prior written consent of the other parties hereto, disclose
to any person or entity (other than those actively and directly participating in
the transactions contemplated by this Agreement, the Debt Restructuring, the
Debt Restructuring Agreements, the Merger and the Merger Agreement) the terms,
conditions or acts relating to the transactions contemplated by this Agreement,
the Debt Restructuring, the Debt Restructuring Agreements, the Merger and the
Merger Agreement (including the fact that discussions are taking place with
respect to such transactions or the status thereof), or the fact that
confidential information has been made available thereto.  In the event that any
of the parties hereto is required by law to make any disclosure otherwise
prohibited under this SECTION 11.1(B), such party shall provide to the other
parties hereto advance written notice of such required disclosure (including
with such advance written notice the text of such required disclosure) at least
two business days prior to such required disclosure.

          11.2 EXPENSES.  Notwithstanding SECTION 2.1(B), each of AHS and Maxum
shall reimburse to GE Medical an amount equal to 40 percent of the legal costs
incurred by GE Medical in connection with the transactions contemplated by this
Agreement, the Debt Restructuring, the Debt Restructuring Agreements, the Merger
and the Merger Agreement from and after July 1, 1995.  Such payments shall be
made by AHS and Maxum within 30 days of the receipt by AHS or Maxum, as the case
may be, of GE Medical's invoice with respect to such legal costs, whether or not
such transactions are consummated.

          11.3 FURTHER ASSURANCES.  Each party hereto shall execute and deliver
such instruments and take such other actions as the other parties hereto may
reasonably require in order to carry out the transactions contemplated by this
Agreement.


                                   ARTICLE 12
                          SURVIVAL AND INDEMNIFICATION

          12.1 SURVIVAL.  All representations, warranties, covenants and
agreements contained in this Agreement or in any document delivered pursuant
hereto shall be deemed to be material and to have been relied upon by the
parties hereto and shall survive the Closing and shall be fully effective and
enforceable for a period of two years following the Closing Date (unless a
different period is specifically assigned thereto), but shall thereafter be of
no further force or effect, except as they relate to claims for indemnification
timely made pursuant to this ARTICLE 12.  The representations and warranties set
forth in this Agreement shall not be affected by any investigation, verification
or examination by any party hereto or by any person or entity on behalf of any
such party except as specifically set forth in an Exhibit, Schedule or document
delivered pursuant to this Agreement.  The indemnification provisions set forth
in this Agreement are nonexclusive and shall not affect any other remedy which
may be available under common law or otherwise.

          12.2 INDEMNIFICATION BY AHS.  AHS shall indemnify and hold harmless GE
Medical from and against any and all loss, damage, expense, claim, liability or
obligation, including court costs, reasonable attorneys' fees and other expenses
for investigating or defending any actions or threatened actions (collectively,
"LOSSES"), related to, caused by or arising from any misrepresentation, breach
of warranty or failure to fulfill any covenant or agreement of AHS contained
herein, together with interest thereon at a floating interest rate (equal at all
times to the rate of interest published by the Wall Street Journal from time to
time as the "prime rate" (the "ANNOUNCED RATE")) from the date upon which such
loss, damage, expense or liability was incurred to the date of payment (but in
no event higher than the highest rate then permissible under law); provided,
however, that nothing herein shall be construed to entitle GE Medical as
indemnitee under this Section to recover interest on Losses, in excess of the
interest that would be payable if the Announced Rate is applied to Losses
(exclusive of any interest component thereof) from the date such Losses were
incurred until the date that such Losses are paid to GE Medical.

          12.3 INDEMNIFICATION BY MAXUM.  Maxum shall indemnify and hold
harmless GE Medical from and against any and all Losses related to, caused by or
arising from any misrepresentation, breach of warranty or failure to fulfill any
covenant or agreement of Maxum contained herein, together with interest thereon
at the Announced Rate, subject to the limitation on payment of interest set
forth in the proviso to SECTION 12.2.

          12.4 INDEMNIFICATION BY THE INSIGHT PARTIES.  The InSight Parties
shall, jointly and severally, indemnify and hold harmless GE Medical from and
against any and all Losses related to, caused by or arising from any
misrepresentation, breach of warranty or failure to fulfill any covenant or
agreement of the InSight Parties contained herein, together with interest
thereon at the Announced Rate, (subject to the limitation on payment of interest
set forth in the proviso to SECTION 12.2).

          12.5 NOTICE.  Any party seeking indemnification pursuant to this
ARTICLE 12 (an "INDEMNIFIED PARTY") shall give prompt written notice to the
indemnifying party (the "INDEMNIFYING PARTY") of the facts and circumstances
giving rise to the claim (the "NOTICE").  Any claim for indemnification asserted
in writing before the second anniversary of the Closing Date shall survive until
resolved or judicially determined.  Upon receipt of the Notice, the Indemnifying
Party receiving the Notice shall have the option to protest any claim or demand
referred to in the Notice, at the Indemnifying Party's own cost and expense.  In
addition, each Indemnified Party may also participate at such party's expense in
such contest or defense.  Such option shall be exercised by the giving of notice
by the Indemnifying Party to each Indemnified Party within 30 calendar days of
receipt of the Notice.  Any claim for indemnification which is not protested by
the 30th day following receipt of notice thereof shall be deemed valid and shall
be due and payable in full on the 31st day following such receipt.


                                   ARTICLE 13
                                   TERMINATION

          13.1 TERMINATION.  This Agreement may be terminated at any time prior
to the consummation of the Merger, and the transactions related thereto:

               (a)  by mutual consent of GE Medical and the InSight Parties;

               (b)  by either GE Medical or the InSight Parties if the Merger
     shall not have been consummated on or before September 30, 1996 despite the
     good faith effort of such party to effect such consummation (unless the
     failure to so consummate the Merger by such date shall be due to the breach
     of this Agreement or the Merger Agreement by the party seeking to terminate
     this Agreement);

               (c)  by GE Medical if (i)(A) there are inaccuracies in the
     representations and warranties of any of the InSight Parties that would
     have a Material Adverse Effect on any of the InSight Parties, (B) there has
     been a material breach on the part of any of the InSight Parties in the
     covenants of such  InSight Party set forth herein, or any failure on the
     part of any of the InSight Parties to comply with its material obligations
     hereunder, or any other events or circumstances shall have occurred, such
     that, in any such case, any of the InSight Parties could not satisfy, on or
     prior to September 30, 1996, any of the conditions to the Closing set forth
     herein or (ii) AHS and Maxum shall not have received the approval by the
     requisite votes cast by the stockholders of AHS and Maxum, respectively,
     with respect to the Merger or any other transaction contemplated in
     connection therewith or herewith;

               (d)  by the InSight Parties if (i)(A) there are inaccuracies in
     the representations and warranties of GE Medical having a Material Adverse
     Effect on its ability to consummate the transaction contemplated hereby or
     (B) there has been any failure on the part of GE Medical to comply with its
     material obligations hereunder, or any other events or circumstances shall
     have occurred, such that, in any such case, GE Medical could not satisfy on
     or prior to September 30, 1996, any of the conditions to the Closing set
     forth in Article 7 of this Agreement, (ii) AHS and Maxum shall not have
     received the approval by the requisite votes cast by the stockholders of
     AHS and Maxum, respectively, with respect to the Merger, or (iii) prior to
     the approval of the Merger by the stockholders of AHS and Maxum, (A) either
     AHS or Maxum receives a firm offer with respect to any transaction (other
     than the Merger) involving any disposition or other change of ownership of
     its stock or material assets (an "ACQUISITION TRANSACTION") that is
     reasonably capable of being financed, (B) in the good faith determination
     of its Board of Directors after consultation with its financial advisors,
     such Acquisition Transaction is financially superior to the Merger and (C)
     its Board of Directors, after consulting with its outside legal counsel,
     determines in good faith that to proceed with the Merger would violate its
     fiduciary duties under applicable law.

          13.2 EFFECT OF TERMINATION.  In the event of a termination of this
Agreement by either the InSight Parties or GE Medical as provided in
SECTION 13.1, this Agreement shall forthwith become void and there shall be no
liability or obligation on the part of GE Medical or the InSight Parties or
their respective officers or directors (other than as provided in SECTION 11.2
and except for breach of the confidentiality provisions of SECTION 11.1, and
except to the extent that such termination results from the breach by a party
hereto of any of its representations, warranties, covenants or agreements set
forth in this Agreement).



                                   ARTICLE 14
                                     GENERAL

          14.1 EXPENSES.  Except as otherwise provided in SECTION 11.2, each
party to this Agreement shall pay its own costs and expenses in connection with
the transactions contemplated hereby.

          14.2 AMENDMENT.  This Agreement cannot be altered, amended, or
modified, in any respect, except by a writing duly executed by all of the
parties hereto.

          14.3 ENTIRE AGREEMENT.  This Agreement is the entire agreement between
the parties with respect to the subject matter hereof and all prior agreements,
understandings, oral agreements and writings are expressly superseded hereby.

          14.4 SEVERABILITY.  The provisions of this Agreement are severable. 
If a court of competent jurisdiction rules that any provision of this Agreement
is invalid or unenforceable, the court's ruling will not effect the validity and
enforceability of the other provisions of this Agreement.

          14.5 CONSTRUCTION.  The parties agree that this Agreement shall be
construed without regard to the draftsman thereof and shall be construed as
though all parties to this Agreement equally participated in its drafting so as
to fairly accomplish the purpose and intentions of the parties hereto and shall
not be construed for or against any party.  Each of the parties acknowledges
that it has been represented by legal counsel of its own choice in connection
with the preparation, review and execution of this Agreement, and that this
Agreement has been executed by the parties with the consent of and on advice of
such counsel.

          14.6 ATTORNEYS' FEES.  In the event any party brings an action to
enforce any of the provisions of this Agreement or the rights of the parties
hereto, the prevailing party shall be entitled to recover reasonable attorneys'
fees and costs.

          14.7 STRICT PERFORMANCE.  The failure of any party to this Agreement
to insist upon strict performance of any of the terms or conditions of this
Agreement, or to exercise any right or remedy, shall not be construed as waiving
subsequent strict performance of any such terms, covenants, conditions, or any
such rights or remedies.

          14.8 GOVERNING LAW.  This Agreement and the legal relations between
the parties shall be governed by and construed in accordance with the internal
laws of the State of Delaware, without giving effect to principles of conflicts
of laws.

          14.9 INTERPRETATION.  Whenever used in this Agreement, the word
"PERSON" includes, without any limitation, natural persons, corporations,
partnerships, associations, organizations, joint ventures, government entities,
and any and every other entity.  The title of the various paragraphs in this
Agreement are intended solely for convenience of reference, and are not intended
and shall not be deemed for any purpose whatsoever to modify, explain or place
any construction upon any of the provisions of this Agreement and shall not
affect the meaning or interpretation of this Agreement.

          14.10  ASSIGNMENT.  This Agreement shall be binding upon and inure to
the benefit of the parties and their respective legal representatives,
successors and assigns, as applicable.  Notwithstanding the forgoing, this
Agreement may not be assigned by AHS, Maxum or InSight without the prior written
consent of GE Medical.

          14.11  INJUNCTIVE RELIEF.  InSight acknowledges that GE Medical would
be irreparably harmed in the event of any breach or violation by InSight of any
of the terms of this Agreement and that remedies at law would be inadequate.  In
the event of any breach or threatened breach of such terms, GE Medical shall be
entitled to obtain, without posting bond, a temporary restraining order and
temporary and permanent injunctive relief restraining and enjoining any such
breach or threatened breach.  The remedies provided for in this SECTION 14.11
shall be in addition to any and all other rights and remedies that may be
available to GE Medical at law, in equity and under this Agreement, all of which
are expressly reserved.

          14.12  ATTORNEYS' FEES.  In the event any party brings an action to
enforce any of the provisions of this Agreement or the rights of the parties
hereto, the prevailing party shall be entitled to recover reasonable attorneys'
fees and costs.

          14.13  ARBITRATION.  Any dispute arising out of, relating to or in
connection with this Agreement shall be resolved by binding arbitration.  The
arbitration shall consist of a panel of three arbitrators from the JAMS panel of
retired judges and shall take place in Milwaukee, Wisconsin, at a place
designated by the parties (or, failing agreement, by the arbitrators) and shall
commence as soon as practicable on a date mutually agreed upon by counsel for
the parties (or the party if a party does not have counsel) and the
arbitrators.  The arbitration proceeding shall be conducted confidentially
and the parties shall take the necessary actions to assure the
confidentiality of the arbitration proceeding.  The arbitration proceeding
shall be in accordance with the then-current rules for arbitration
established by JAMS, insofar as such rules are not inconsistent with the
provisions of this Agreement.  The party desiring to institute arbitration
shall serve written notice to the other party (with copies to all parties to
this Agreement).  InSight shall name one arbitrator and GE Medical shall
name a second arbitrator and the two arbitrators so named shall name a third
arbitrator.  The names of the two arbitrators named by GE Medical and
InSight shall be submitted within 45 days of the notice instituting
arbitration.  When such arbitrators have chosen the third arbitrator, such
three arbitrators shall proceed with the arbitration.  The prevailing party
in any such arbitration proceeding (or legal or equitable action instituted
as authorized elsewhere in this Agreement) shall be entitled to an award of
attorneys' fees and costs in addition to any other relief awarded.  Any
award rendered in such an arbitration proceeding shall be final and binding
on the parties and may be entered in any court having jurisdiction over the
parties and/or the subject matter thereof.  The arbitrators shall have
no jurisdiction or authority to add to, detract from, or alter in any way the
provisions of this Agreement, but shall limit their considerations and decision
to the interpretation and application of this Agreement to the subject matter
presented to them.  Nothing contained in this SECTION 14.13 shall restrict GE
Medical's right to institute and prosecute any legal or equitable action in
court for temporary restraining orders and temporary and permanent injunctive
relief or otherwise as deemed appropriate by GE Medical.
