                                    RECITALS

         A. Corporation, after careful study, has concluded that there is a need
in Huntington Beach for a medical center specializing in performing a variety of
medical imaging and diagnostic services by experienced physicians at reasonable
cost.

         B. Corporation has a comprehensive system for establishing and
providing financial and related management to such a medical center which makes
available to qualified physicians a fully staffed facility, equipment, supplies,
management, capital, marketing services, and systems necessary to provide a
large volume of medical imaging and diagnostic services to patients at
reasonable cost. These services will be obtained from Medical Imaging Centers of
America, Inc. ("MICA").

         C. Corporation desires to make its system available to physicians who
are capable of offering high quality services to the public at a competitive
cost. To that end, Corporation has committed substantial resources, and has
incurred substantial expenses and future obligations to develop the medical
imaging center located at 7677 Center Avenue, Huntington Beach, California 92647
(hereinafter referred to as the "Center").

         D. Physician Group desires to contract with Corporation for use of
Corporation's management services and system of delivering medical imaging and
diagnostic care, a sublease for the Center, and a license for use of any
appropriate trade names and marks which Corporation may own or own rights to
license.

highest skills and best efforts to cause the practice at the Center to grow in
volume and profitability. To the latter end, except for undertaking bona fide
charity cases on a basis customary for physicians in the Huntington Beach area,
without written consent of the Corporation, Physician Group shall only use the
Center for performance of medical services which are compensable by the payment
of professional fees established under Section 6.3, or as approved by the
Corporation.

and MICA business system for operating a medical imaging and diagnostic center,
including all policies, procedures, operating manuals, forms, customer lists,
contracts, and other information regarding such system. Physician Group
acknowledges and agrees that such information constitutes trade secrets of
corporation and MICA. Physician Group hereby waives any and all right, title and
interest in and to such trade secrets and agrees to return all copies of such
trade secrets and information related thereto, at its expense, upon termination
of the Agreement.

         5.2 Confidentiality. Physician Group acknowledges and agrees that
Corporation and MICA are entitled to prevent its competitors from obtaining and
utilizing its trade secrets. Physician Group agrees to hold the trade secrets of

them to be disclosed directly or indirectly to any person or entity other than
persons engaged by Physician Group for use in the course of their employment at
the Center, without the prior written consent of Corporation and MICA. Physician
Group acknowledges its confidential relationship to Corporation and the

termination of this Agreement, disclose to anyone other than persons employed at
the Center who use the information in the course of their employment any
confidential or proprietary information or trade secret of Corporation obtained
by it. Physician Group also agrees to place under legal obligation to treat such
information as strictly confidential any persons to whom said information is
disclosed for the purpose of performance.

         5.3 Successor Medical Group. Upon termination of this Agreement, or the
sublease of the Center for any reason, whichever first occurs, Corporation shall
have the immediate right, in its sole discretion, to designate a professional
corporation, partnership or sole proprietor as successor to Physician Group at
the Center. If such professional corporation, partnership or sole proprietor is
composed solely of duly licensed physicians, they shall be entitled to retain
and utilize all existing customer lists and patient records at the Center.
Corporation agrees that all records transferred to Physician Group's successor
shall be maintained as long as required by law regulating retention of medical
records, and copies of said records shall be made available to


                                        6
   7
Physician Group at its expense, if required for the purpose of defending any
malpractice claim against Physician Group, or for the purpose of providing
medical care. The rights of the parties under this section shall survive
termination of this Agreement.

                                  Compensation

         6.1 Inducement to Enter Agreement. As partial consideration, and as an
inducement to Physician Group for entering this Agreement, Corporation shall be
responsible for any losses related to the operation of the Center which do not
arise from wrongful or negligent acts or omissions of Physician Group.

         6.2 Corporation's Risk. Corporation has incurred substantial expenses
and future obligations to establish the Center, the system for the delivery of
medical imaging and diagnostic services, including fees for consultants and
other professionals, salaries for responsible staff, interest expenses, lease
obligations, and costs of equipping the Center. Corporation has also assumed
substantial obligations associated with the continuing operation of the Center.
Although there is uncertainty about the profitability of the Center during the
initial years of operation, Corporation is assuming responsibility for losses as
provided in Section 6.1. The parties therefore recognize and agree that in order
for Corporation to receive a fair and reasonable return for its expenses and
risks, a fair return for lease of premises, services, and the use of its trade
names and marks hereunder, as well as to permit the necessary accumulation of
capital to establish and maintain a first rate and fully equipped Center, a goal
the parties hereto agree to be desirable, the total payments to Corporation
should increase in future years.

         6.3 Professional Fees. Physician Group, shall in consultation with
Corporation, establish a schedule of fees and charges for medical services at
the Center.

         6.4 Billing and Collections. Billings to patients for all services
rendered at the Center shall be in the name of Physician Group. Corporation, or
its delegate, shall serve as billing and collection agent for Physician Group,
and shall be diligent and timely in the performance of billing and collection
services. However, Corporation does not guarantee collection and shall not be
responsible for any loss to Physician Group as a result of inability to collect
fees and charges.

         6.5 Intention of the Parties. It is the intention of the parties hereto
that from the revenues of the Center Physician Group shall be fairly and
reasonably compensated for its professional services and those of the physicians
engaged by it, and Corporation shall be fairly and reasonably compensated for
the sublease of the Center, the licensing of trade names and marks, the
provision of services by it pursuant to this Agreement, and for the expenses,
obligations, and risks assumed by it in connection with the establishment and
operation of the Center and the operation of the Corporation system.

         6.6 Fair and Reasonable Compensation of Physician Group. The parties
hereto agree Physician Group will be fairly and reasonably compensated for its
services and those of the physicians it engages by retaining in the aggregate
twenty percent (20%) of the revenues actually collected for each medical imaging
diagnostic or other medical procedure ("medical services") performed by
Physician Group at the Center. For purposes of this Agreement, aggregate
revenues collected shall mean all collected receipts for medical imaging,
diagnostic and other medical procedures performed at the Center, including
charges for use of equipment, supplies, facilities and Center personnel in
connection with performance of medical services.

         6.7 Fair and Reasonable Compensation to Corporation. Any revenues or
receipts in excess of those retained by Physician Group as provided in Section
6.6 hereof shall be paid to Corporation as compensation for the sublease of the
Center, provision of services under this Agreement, the licensing of trade names
and marks to Physician Group, and for its expenses, obligations, and risks in
connection with the establishment of the Center, and the operation of the
Corporation system. Said compensation includes the total rent to Corporation for
the Center subleased by Physician Group.

         6.8 Remittance. All monies which Physician Group is entitled to retain
pursuant to Section 6.1 and all monies which Corporation is entitled to receive
pursuant to Section 6.7 shall be accounted for and disbursed weekly.

                                    AMENDMENT

         AMENDMENT TO the Management, Licensing and Facilities Agreements
entered into by and between predecessors to MAGNETIC IMAGING MEDICAL GROUP,
INC., a California professional corporation (hereinafter referred to as
"Physician Group" and MEDICAL IMAGING CENTERS OF AMERICA, INC., a California
corporation ("MICA") which wholly-owned subsidiaries are MICA CAL I, Inc., a
California corporation ("M-I") and the managing general partner of Long Beach
Medical Imaging Center, Ltd., a California limited partnership ("Long Beach"),
MICA CAL II, INC., a California corporation ("M-III") and MICA CAL IV, INC., a
California corporation ("M-IV").

                                 R E C I T A L S

         A. On March 28, 1984, Long Beach entered into a Management, Licensing
and Facilities Agreement with the predecessor to the Physician Group. A true and
correct copy of that Agreement is attached hereto as Exhibit A (the "A
Agreement").

         B. On March 14, 1988, M-IV entered into a Management, Licensing and
Facilities Agreement with the predecessor to the Physician Group. This Agreement
was extended on May 29, 1992. A true and correct copy of that Agreement as
extended is attached hereto as Exhibit B (the "B Agreement").

         C. On February 3, 1992, M-IV entered into a Management, Licensing and
Facilities Agreement with the predecessor to the Physician Group. A true and
correct copy of that Agreement is attached hereto and marked as Exhibit C (the
"C Agreement").

         D. On July 1, 1994, M-III entered into a Management, Licensing and
Facilities Agreement with the predecessor to the Physician Group. A true and
correct copy of that Agreement is attached hereto and marked as Exhibit D (the
"D Agreement").

         E. The A Agreement is an agreement which has a term which does not
terminate except on the occurrence of certain events while the B, C, and D
Agreements have terms which end on different dates in 1997 and 1998. MICA wished
to place limits on the term of the A Agreement and the Physician Group is
willing to permit such limits and both parties wish each of the Agreements to be
coterminous. All of the parties wish to provide for certainty and continuity of
service in their relationship as well as revise certain of the compensation
provisions and clarify certain other matters.

         NOW THEREFORE, in consideration of their mutual covenants and promises
and for other good and valuable consideration, receipt of which each party
acknowledges, the parties agree as follows:


   16
         1. Term.

                  The term as set forth in each of the Agreements (Section 7.1
of Exhibits A, B, C and D) is hereby revised to read as follows:

                  7.1 Term. The term hereunder shall commence January 1, 1996
and shall continue for five (5) years. Provided that Physician Group is not in
material default pursuant to this Agreement then and in that event Physician
Group shall have the right to extend the term of this Agreement for two (2)
consecutive five (5) year terms so long as it shall give written notice to the
other party no less than sixty (60) days prior to the end of a term hereunder.
If a party believes a material default has occurred it shall promptly give
written notice to the other party specifying the nature of the material default
and providing a recommended method of cure. The notified party shall have ninety
(90) days to correct the material default either in accordance with the
suggested methodology or by an alternate equally effective methodology. The
failure to provide notice within thirty (30) days of an event giving rise to a
material default shall be deemed a waiver of such default. Notwithstanding
anything to the contrary set forth in this Agreement, it is understood and
agreed that this Agreement is attached to the assets of the Center. To the
extent the Center or its assets are sold, assigned or otherwise transferred,
this Agreement must be transferred and accepted in full by the acquirer as a
condition of such acquisition, assignment or transfer.

         2. Compensation.

                  (a) The Compensation as set forth at Section 6.6 in each of
those Agreement attached as Exhibits A and B is hereby revised to read as
follows:

                           6.6 Compensation of Physician Group. The parties
hereto agree Physician Group will be fairly and reasonably compensated for its
services by retaining in the aggregate Twenty percent (20%) of the first Two
Hundred Thousand Dollars ($200,000) of revenues each month actually collected
for each medical imaging diagnostic or other medical procedure ("medical
services") performed by Physician Group at the Center with Physician Group
receiving Eighteen percent (18%) of such revenues in excess of Two Hundred
Thousand Dollars ($200,000) actually collected each month. For purposes of this
Agreement aggregate revenues collected shall mean all collected receipts for
medical imaging, diagnostic and other medical procedures performed at the
Center, including charges for use of equipment, facilities and Center personnel
in connection with performance of medical services (the aggregate of the
"Professional" and "Technical" components). Notwithstanding the foregoing, in
those instances in which Technical only services are performed at the Center, or
in which injections are provided, Physician Group shall receive an amount equal
to Ten percent (10%) of the revenues actually collected for such services each
month.

                  (b) The compensation as set forth in Section 6.6 in each of
Exhibits C and D is hereby revised to read as follows:


   17
                  6.6 Compensation of Physician Group. The parties hereto agree
Physician Group will be fairly and reasonably compensated for its services by
retaining in the aggregate Twenty percent (20%) of the first One Hundred
Thousand Dollars ($100,000) of revenues each month actually collected for each
medical imaging diagnostic or other medical procedure ("medical services")
performed by Physician Group at the Center with Physician Group receiving
Eighteen percent (18%) of such revenues in excess of One Hundred Thousand
Dollars ($100,000) actually collected each month. For purposes of this Agreement
aggregate revenues collected shall mean all collected receipts for medical
imaging, diagnostic and other medical procedures performed at the Center,
including charges for use of equipment, facilities and Center personnel in
connection with performance of medical services (the aggregate of the
"Professional" and "Technical" components). Notwithstanding the foregoing, in
those instances in which Technical only services are performed at the Center, or
in which injections are provided, Physician Group shall receive an amount equal
to Ten percent (10%) of the revenues actually collected for such services each
month in recognition of their supervisorial responsibilities.

         3. Statement of Revenues. A new Section 6.10 shall be added to Exhibit
A and a new Section 6.9 to Exhibits B, C and D which provides as follows:

                  6.9[10] Statement of Revenues. Partnership [Corporation] shall
furnish to Physician Group a statement of revenues generated by Physician Group
upon or as to which a fee to be paid to Physician Group hereunder is calculated
at the end of every month. This statement shall be submitted to Physician Group
on the tenth (10th) day of each month reflecting the previous month's revenue
from services rendered by Physician Group. Each statement shall be signed and
certified to be correct by Partnership [Corporation] or its authorized
representative. Partnership [Corporation] shall keep in the Center premises full
and accurate books of account, records, cash receipts, and other pertinent data
showing its revenues. Such books of account, records, cash receipts and other
pertinent data shall be kept for a period of two (2) years. Physician Group
shall be entitled during the term and within two (2) years after expiration or
termination of this Agreement to inspect and examine all of Partnership's
[Corporation's] books of account, records, cash receipts, and other pertinent
data relative only to the revenues involving the Center, so that Physician Group
can ascertain Center's revenues. Partnership [Corporation] shall cooperate fully
with Physician Group in making the inspection. Physician Group shall also be
entitled once during each year of the Agreement and once after expiration or
termination to an examination of Center's books of account, records, cash
receipts and other pertinent data to determine Center's revenues by a certified
public accountant to be designated by Physician Group, and who will be paid
solely by Physician Group, unless such review shall disclose an understatement
by Center of two percent (2%) or more in which case all expenses of such
examination will be paid by Partnership [Corporation].

         4. Reference. It is hereby agreed between the parties hereto that
wherever the term "Physicians" or "Physician Group" appears in Exhibits A, B, C
and D it shall be deemed to mean "Magnetic Imaging Medical Group, Inc., a
California professional corporation.


   18
         5. Indemnification. MICA and Long Beach, jointly and severally, agree
to indemnify and hold Physician Group together with its predecessors, harmless
against any and all liabilities which it might incur in connection with its
service as a General Partner of Long Beach. Physician Group shall promptly
notify MICA of the existence of any claim, demand or other matter involving
liabilities to third parties to which MICA's indemnification obligations would
apply and shall give MICA a reasonable opportunity to defend the same at its own
expense and with counsel of its own selection. If MICA, within a reasonable time
after notice, fails to defend, Physician Group shall have the right, but not the
obligation, to undertake the defense of and to compromise or settle (exercising
reasonable business judgment) the claim or other matter on behalf of MICA.

                           [INTENTIONALLY LEFT BLANK]
