                      -----------------------------------


     THIS MASTER DEBT RESTRUCTURING AGREEMENT (this "Agreement") is entered into

corporation acting through GE Medical Systems ("GE Medical"), General Electric
Capital Corporation, a New York corporation ("GE Capital"), and InSight Health
Services Corp., a Delaware corporation ("InSight"), American Health Services
Corp., a Delaware corporation ("AHS"), Maxum Health Corp., a Delaware
corporation ("MHC"), and each of the undersigned subsidiaries of MHC (the "MHC

                                - - - - - - - -

     A.   GE Capital is a financial institution which finances, among other
things, equipment leases and purchases and GE Medical is a primary supplier of
equipment and services to AHS, MHC and the MHC First-Tier Subsidiaries.

     B.   GE Capital has entered into a Loan and Security Agreement dated as of
June 1, 1993 with AHS (the "Existing AHS Agreement"), pursuant to which GE
Capital extended to AHS a term loan in the principal amount of $15,188,229.68,
evidenced by a Promissory Note dated June 1, 1993 (the "Original Term Note")
made by AHS in favor of GE Capital, to finance (i) the buy out by AHS of certain
equipment leases between GE Medical, as lessor, and AHS, as lessee, and (ii) the
purchase by AHS of certain equipment from GE Medical.  Also pursuant to the
Existing AHS Agreement, AHS has issued in favor of GE Capital the Promissory
Note dated June 1, 1993 in the principal amount of $1,810,851.78 to provide for
the payment of, among other things, state sale taxes imposed as a result of the

the Existing AHS Agreement are secured by the collateral described in the
Existing AHS Agreement.

     C.   GE Capital has also entered into the Asset Purchase Agreement dated as

amount of $14,280,000.  The remaining obligations of AHS under the Original PCC
Note were restructured effective as of May 1, 1994 by reducing the then
outstanding principal amount of $9,582,205 to $8,000,000, evidenced by the
Amended and Restated Promissory Note dated April 12, 1994 made by AHS in favor

dated as of April 12, 1994
<PAGE>

between AHS and GE Capital for the purpose of amending the amortization schedule

(the "Existing Maxum Agreement") and (ii) certain installment sales contracts,

Financing Agreements are secured by the collateral described in the Maxum
Security Agreement and the Maxum Financing Agreements.

     F.   AHS, MHC, InSight and GE Medical have entered into the Preferred Stock

     G.   AHS, MHC and InSight have also entered into the Agreement and Plan of
Merger, dated as of February __, 1996 (the "Merger Agreement"), contemplating
the merger of two newly-formed wholly-owned subsidiaries of InSight with and

           (f) The Existing Maxum Agreement is amended by deleting the
definition of "Warrant" in Section 1.61 and all other references therein to

           (g) Section 5.1(N) of the Existing Maxum Agreement is amended in its
entirety to read in full as follows:

               "(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 Schedule 3.1(g)
     attached to the Restructuring Agreement.  All policies of insurance
     required to be maintained under this Section 5.1(N) shall be in form and
     with insurers reasonably acceptable to GE.  All policies of insurance on
     that portion of the Collateral in which GE holds a first Lien shall contain
     an endorsement in form and substance acceptable to GE and showing GE as
     loss payee with respect to such Collateral.  Such endorsement or
     independent instrument furnished to GE shall provide that the insurance
     company providing any such policy of insurance will give GE at least 30
     days' prior written notice before any such policy or policies of insurance
     shall be materially altered or canceled, and that no act or default of MHC
     or any of the First-Tier Subsidiaries or any other Person shall affect the
     right of

                                     -26-
<PAGE>

     GE to recover under such policy or policies of insurance in case of loss or
     damage. Each of MHC and the First-Tier Subsidiaries shall deliver to GE the
     original (or a certified copy) of each such policy of insurance and
     evidence of payment of all premiums therefor. In addition, MHC and the
     First-Tier Subsidiaries shall notify GE promptly of any occurrence causing
     a material loss to any real or personal property covered by any such
     insurance and the estimated (or actual, if available) amount of such loss.
     Each of MHC and the First-Tier Subsidiaries shall direct all insurers under
     such policies of insurance to pay all proceeds payable thereunder with
     respect to the Collateral directly to GE. Such proceeds shall be held by GE
     to be applied, first, to GE's expenses in settling, prosecuting and
     defending any insurance claim and, then, so long as no Default or Event of
     Default shall have occurred and be continuing, to the restoration or repair
     of any portion of the Collateral that has been damaged or destroyed to the
     same condition, character and value as existed prior to such damage or
     destruction. In the event that a Default or an Event of Default shall have
     occurred and be continuing, GE shall have the right to apply all such
     insurance proceeds towards repayment of the Liabilities secured by the
     Collateral. Each of MHC and the First-Tier Subsidiaries shall forthwith, at
     the request of GE, duly execute and deliver instruments of assignment of
     any such insurance policies to comply with this Section 5.1(N) and cause
     the insurers with respect to such policies to acknowledge notice of such
     assignment. After the occurrence and during the continuance of a Default or
     an Event of Default, each of MHC and the First-Tier Subsidiaries
     irrevocably makes, constitutes, and appoints GE (and all officers,
     employees or agents designated by GE) as true and lawful attorney (and
     agent-in-fact) therefor for the purpose of making, settling and adjusting
     claims under such policies of insurance that relate to the Collateral
     (provided that GE shall consult therewith prior to finally making, settling
     or adjusting claims under such policies of insurance) or endorsing the name
     thereof on any check, draft, instrument or other item of payment for the
     proceeds of such policies of insurance that relates to the Collateral. In
     the event MHC or any of the First-Tier Subsidiaries at any time or times
     hereafter shall fail to obtain or maintain any of the policies of insurance
     required hereunder or shall fail to pay any premium in whole or in part,
     relating thereto, GE, without waiving or releasing any Liabilities or
     Default or Event of Default hereunder, may (but shall not be obligated to)
     at any time or times thereafter obtain and maintain such policies of
     insurance and pay such premiums and take such other action with respect
     thereto which is deemed advisable thereby. All sums so disbursed by GE,
     including attorneys' fees, court costs, expenses and other charges relating
     thereto, shall be payable, on demand, by MHC and the First-Tier

                                     -27-
<PAGE>

     Subsidiaries to GE and shall be additional Liabilities hereunder secured by
     the Collateral.

           GE reserves the right at any time, upon review of the risk profile of
     MHC and the First-Tier Subsidiaries, to require additional forms and
     insurance to, in GE's reasonable opinion, adequately protect GE's interests
     in the Collateral."

           (h) Section 5.1 of the Existing Maxum Agreement is amended by
inserting the following provision as Section 5.1(S) therein:

               "(S)  Financing Statements.  MHC and the First-Tier Subsidiaries
                     --------------------                                     
     hereby authorize GE to file one or more Financing Statements, and
     amendments thereto, relative to all or any part of the Collateral without
     the signature of MHC or any of the First-Tier Subsidiaries where permitted
     by law.  MHC and the First-Tier Subsidiaries hereby agree to execute,
     within 10 days after receipt of GE's written request, such Financing
     Statements as may be necessary to replace, prior to expiration, any
     Financing Statements delivered to GE on the Closing Date and to evidence
     GE's continuing security interest in the Collateral."

           (i) Section 5.2 of the Existing Maxum Agreement is amended by
inserting the following provision as Section 5.2(T) therein:

     whether by guaranty, endorsement, agreement to purchase or repurchase,
     agreement to supply or advance funds or otherwise; provided, however, that

           (iii)  endorsements of negotiable instruments for collection in the
           ordinary course of business."

           (j) Section 5.2(H) of the Existing Maxum Agreement is amended in its
entirety to read in full as follows:

               "(H) Capital Expenditures.  Neither MHC nor any of the First-Tier
                    --------------------

     Notwithstanding the foregoing, this Section 5.2(H) shall not apply to

     pursuant to transactions with GE. 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 hereof and shall be approved or disapproved
     by GE in accordance with Section 5.6 hereof 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 $50,000 shall be made by

Accountant under paragraph (a) above, then such GE Party and InSight shall

     7.3  Payment of Charges.  Except as otherwise provided in Section 7.4 or
          ------------------                                                
elsewhere in this Agreement and except as otherwise provided in the next
succeeding sentence, InSight shall pay all charges, whether payable on account
of the execution, delivery or performance of this Agreement and the other
Restructuring Documents, the creation of any of the Liabilities hereunder by
reason of any existing or hereafter enacted federal, state or other regulation
or

                                     -48-
<PAGE>

statute or otherwise, promptly when due where the failure to so pay would
have a Material Adverse Effect upon InSight. Except as provided in Section 7.4,
InSight shall pay promptly when due all withholding taxes, whether relating to
payment of employee wages or otherwise (collectively, the "Withholding
Charges"). InSight shall indemnify the GE Parties and hold the GE Parties
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
Internal Revenue Code and any comparable provisions under state or local law).
In the event that InSight fails to pay any charges described in this Section 7.3
or fails to obtain promptly the discharge of such charges, InSight shall so
advise the GE Parties in writing and, whether or not InSight so advises the GE
Parties, the GE Parties may, in their sole and absolute discretion, without
waiving or releasing any obligation or liability of InSight 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 the GE
Parties reasonably deem advisable; provided, however, that the GE Parties shall
                                   --------  -------                          
provide InSight with ten (10) days' prior notice before paying any charge of a
type described in this Section 7.3.  All amounts so paid by the GE Parties and
any related expenses, including attorneys' fees, court costs and other charges,
shall be payable, upon demand, by InSight to the GE Parties.

     7.4  Contesting Charges.  Except as otherwise provided below, InSight may
          ------------------                                                 
dispute any charges without prior payment, even if such non-payment may cause a
Lien to attach to InSight's Property, provided that InSight shall have given the
GE Parties 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 $100,000 in the aggregate, at any time, InSight shall
give the GE Parties such additional assurances as the GE Parties reasonably deem
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 any of the GE Parties in relation to the disputed
Withholding Charge, then InSight shall, if reasonably required by any of the GE
Parties, immediately pay the disputed Withholding Charge liability, and
thereafter shall only contest such Withholding Charge through an alternative
method.

     7.5  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 any of the
Credit Parties or any of the GE Parties that accrued and remain unperformed as
of the Restructuring Termination Date.

     7.6  Requests for Consent of GE Parties.  Any request by InSight for the
          ----------------------------------                                
written consent of the GE Parties prior to taking any action prohibited by
Section 7.2 hereof as described in such Section, shall be in writing and shall
include a detailed description that is reasonably acceptable to the GE Parties
of the proposed action to be taken by InSight. The GE Parties shall accept or
reject, in their

                                     -49-
<PAGE>

sole and absolute discretion, such request within 10 Business Days following the
GE Parties' receipt of InSight's request for consent; provided, however, that
                                                      --------  -------
any failure by the GE Parties to respond to such request shall be deemed to be a
rejection thereof.

shall have the following rights and remedies:

          (a)  the GE Parties shall have the right to declare all or any portion
of the Liabilities of the Credit Parties owed to the GE Parties immediately due
and payable, whereupon all or any portion of such 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 the Credit Parties.

          (b)  The GE Parties and their respective agents and representatives
shall have the right to enter upon the premises of each of the Credit Parties,
and such Credit Party shall use reasonable efforts to cause the GE Parties and
their respective agents and representatives to have the right to enter upon the
premises of any other place or places where the Collateral is located and kept
through self-help and without judicial process without first obtaining a final
judgment or giving such Credit Party notice and opportunity for a hearing on the
validity of the GE Parties' claims and without any obligation to pay rent to
such Credit Party or such Credit Party's lessee.

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

Agreement and the other Restructuring Documents and applicable law, the GE
Parties 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 the GE Parties are able to effect a sale, lease or other
disposition of the Collateral, the GE Parties shall have the right to use or
operate the Collateral, or any part thereof, to the extent that the GE Parties
deem appropriate for the purpose of preserving the Collateral or its value or
for any other purpose deemed appropriate by the GE Parties.  The GE Parties
shall have no obligation to any Credit Party to maintain or preserve the rights
of such Credit Party as against third parties with respect to the

                                     -55-
<PAGE>

Collateral while the Collateral is in the possession of the GE Parties. The GE
Parties may, if they so elect, seek the appointment of a receiver or keeper to
take possession of the Collateral and to enforce any of the GE Parties' remedies
with respect to such appointment without prior notice or hearing.

          (f)  The GE Parties 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 the GE Parties, 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.  The GE
Parties and their respective agents and representatives shall have the right to
conduct such sales on each of the Credit Parties' premises or elsewhere and
shall have the right to use such Credit Party's premises, and InSight shall use
reasonable efforts to cause any lessee of the Collateral to permit the GE
Parties and their respective 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 the GE Parties deem necessary or advisable.  Each of the Credit
Parties' rights under all licenses and certificates of need, to the extent
transferable, and all franchise agreements shall inure to the GE Parties'
benefit.  The GE Parties 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 of the Credit Parties owed to the GE Parties.  Except as otherwise
provided by law, the proceeds realized from the sale of any Collateral may be
applied by the GE Parties first to the reasonable costs, expenses, and
attorneys' fees and expenses incurred by the GE Parties 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 of the
Credit Parties owed to the GE Parties, as the GE Parties, in their sole and
absolute discretion, may elect.  If any deficiency shall exist after the
application of such proceeds, the Credit Parties shall remain liable to the GE
Parties therefor.

     9.4  Notice of Disposition of Collateral.  Any notice required to be given
          -----------------------------------

any other intended action by the GE Parties, which is given in accordance with
Section 10.12, 15 days 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 the Credit Parties.

     9.5  Right of Set-Off.  Upon the occurrence and during the continuance of
          ----------------                                                   
any Event of Default, the GE Parties are hereby authorized at any time and from
time to time, to the fullest extent permitted by law, upon three Business Days
prior written notice to the Credit Parties, to set-off, appropriate and apply
any and all funds in the possession of any of the GE Parties, all deposits

                                     -56-
<PAGE>

(general or special, time or demand, provisional or final) at any time held and
other Indebtedness at any time owing by any of the GE Parties to or for the
credit or the account of the Credit Parties, against any and all of the
Liabilities of the Credit Parties owed to the GE Parties now or hereafter
existing that are then due and payable, whether by maturity or acceleration,
irrespective of whether or not (a) any of the GE Parties shall have made or be
entitled to make any demand under the Restructuring Documents or other
applicable agreements or (b) any of the GE Parties shall have declared the
principal of and interest under the Restructuring Documents and such other
Liabilities due hereunder and thereunder to be due and payable and although such
obligations and Liabilities, or any of them shall be contingent or unmatured.
The exercise by any of the GE Parties of the aforesaid right of set-off shall be
effective as of the time such GE Party restricts such Credit Party's access to
any such deposits. The rights of the GE Parties under this Section 9.5 are in
addition to any other rights and remedies (including, without limitation, other
rights of set-off) which the GE Parties may have under the Restructuring
Documents, other applicable agreements and applicable law.

     9.6  Appointment of GE Parties as Credit Parties' Lawful Attorneys.  Each
          -------------------------------------------------------------      
of the Credit Parties hereby irrevocably designates, makes, constitutes and
appoints each of the GE Parties and all Persons designated by such GE Party as
such Credit Party's true and lawful agent and attorney-in-fact during the
continuance of a Default or an Event of Default for the purposes set forth in
this Section 9.6.  Accordingly, upon and after the occurrence of an Event of

at any time or times hereafter, to require strict performance by any Credit
Party of any provision of this Agreement, shall not waive, affect or diminish
any right of the GE Parties thereafter to demand strict compliance and
performance therewith. Any suspension or waiver by the GE Parties of an Event of
Default under this Agreement shall not suspend, waive or affect any other Event
of Default by any Credit Party 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 the

waived by the GE Parties unless such suspension or waiver is in writing signed

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 the GE Parties would otherwise have.

Agreement, each of the Credit Parties waives:  (a) presentment, demand, and
protest and notice of presentment, protest, default, non-payment, 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 any of the GE Parties under or pursuant to which
such Credit Party may in any way be liable, and such Credit Party hereby
ratifies and confirms whatever any of the GE Parties may do in this regard; (b)
notice prior to taking possession or control of the Collateral or any bond or
security that might be required by any court prior to allowing the GE Parties to
exercise any of their remedies; and (c) the benefit of all valuation,
appraisement, and exemption laws.  If and to the extent that any obligation of
each of the Credit Parties to any of the GE Parties shall be considered an
obligation of guaranty or suretyship, then the following waivers shall apply:

               (i)    Such Credit Party agrees that no election to proceed in
one form of action or against any party or on any obligation shall constitute a
waiver of any GE Party's right to proceed in any other form of action for a
deficiency, except to the extent such GE Party realizes payment by such action,
notwithstanding the effect of such action upon such Credit Party's rights of
subrogation, reimbursement or indemnity, if any, against any Person; and

               (ii)   Such Credit Party agrees that the GE Parties shall be
under no obligation and expressly waives the right to require the GE Parties:
(A) to marshall any assets in favor of such Credit Party, (B) to proceed first
against any guarantor or any

                                     -60-
<PAGE>

Property of guarantor or against any collateral, (C) to enforce first any other
guaranty obligations with respect to, or security for, the Liabilities or (D) to
pursue any other remedy in the GE Parties' power that such Credit Party may or
may not be able to pursue itself and that may lighten such Credit Party's
burden, any right to which such Credit Party hereby expressly waives.

     10.7  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.

     10.8  Parties.  This Agreement shall be binding upon and shall inure to the
           -------                                                             
benefit of the respective successors and assigns of the GE Parties and the
Credit Parties, including any trustee or interim trustee of any Credit Party

GE Parties are hereby specifically authorized to assign or sell any or all of
their rights and obligations under this Agreement to any party without the prior
written consent of the Credit Parties.

provided in this Agreement by specific reference to the applicable provision of

            ------------------------------------------------           
otherwise expressly provided in any other related agreements in all respects,
including all matters of construction, validity and performance, this Agreement
and the Liabilities arising hereunder shall be governed by, and construed and

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
