                            AND FACILITIES AGREEMENT

         This Agreement is made effective as of March 28, 1984 by and between
LONG BEACH MEDICAL IMAGING CENTER, LTD., a California limited partnership
(hereinafter referred to as "PARTNERSHIP"), and LANCE SIEGER, M.D., JOEL B.
LEVINE, M.D. and KEITH R. BURNETT, M.D. (herein after referred to as
"Physicians").

                                    RECITALS

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

         B. PARTNERSHIP has a comprehensive system for establishing and
providing financial and related management to such a medical center which makes
available to qualified physicians the facilities, equipment, supplies,
management, capital, staffing support, marketing services, and systems necessary
to provide a large volume of medical imaging and diagnostic services to patients
at reasonable cost, which PARTNERSHIP has obtained through arrangements with
Medical Imaging Centers of America, Inc. ("MICA"), an affiliate of PARTNERSHIP.

         C. PARTNERSHIP 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, PARTNERSHIP has committed substantial resources, and has
incurred substantial expenses and future obligations to develop the Center
located in the greater Long Beach area, California (hereinafter referred to as
the "Center"). The exact location of the Center has not yet been determined, and
once a site has been selected the precise address will be set forth in a
separate memorandum which will be attached hereto and incorporated herein by
reference.

         D. Physicians desire to contract with PARTNERSHIP for use of
PARTNERSHIP'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 PARTNERSHIP may own or own rights to
license.

parties is that PARTNERSHIP shall not participate in any manner in the medical
services rendered by Physicians in the conduct of their medical practice at the

                                    ARTICLE V

             Proprietary Interest and Rights of PARTNERSHIP and MICA

         5.1 Proprietary Interests of PARTNERSHIP and MICA. Physicians (and each
of them) recognize the proprietary interest of PARTNERSHIP and MICA in the
PARTNERSHIP 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.
Physicians (and each of them) acknowledge and agree that such information
constitutes trade secrets of PARTNERSHIP and MICA. Physicians (and each of them)
hereby waive any and all right, title and interest in and to such trade secrets
and agree to return all copies of such trade secrets and information related
thereto, at its expense, upon termination of the Agreement.

         5.2 Confidentiality. Physicians (and each of them) acknowledge and
agree that each of PARTNERSHIP and MICA is entitled to prevent its competitors
from obtaining and utilizing its trade secrets. Physicians (and each of them)
agree to hold the trade secrets of PARTNERSHIP and MICA in strictest confidence
and not to disclose them or allow them to be disclosed directly or indirectly to
any person or entity other than persons engaged by Physicians for use in the
course of their employment at the Center, without the prior written consent of
PARTNERSHIP and MICA. Physicians (and each of them) acknowledge their fiduciary
obligations to PARTNERSHIP and MICA and the confidentiality of their
relationship with PARTNERSHIP and MICA and of any information relating to the
services and business methods of PARTNERSHIP and MICA which they may obtain
during the term of this Agreement. Physicians (and each of them) shall not,
either during the term of this Agreement, or at any time after the expiration or
sooner 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 PARTNERSHIP or
MICA obtained by them. Physicians (and each of them) also agree to place any
persons to whom said information is disclosed for the purpose of performance
under legal obligation to treat such information as strictly confidential.

         5.3 Successor Medical Group. Upon termination of this Agreement, or the
sublease of the Center, whichever first occurs, PARTNERSHIP shall have the
immediate right, in its sole discretion, to designate a professional
corporation, partnership or sole proprietor as successor to Physicians at the
Center. If such professional corporation, partnership or sole proprietor is
composed solely of duly licensed physicians, or other licensed health care
professionals, they shall be entitled to retain and utilize all existing
customer lists and patient records at the Center. PARTNERSHIP agrees that all
records transferred to Physicians' 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 Physicians at their expense, if required for
the purpose of defending any malpractice claim against Physicians or any of
them.

                                   ARTICLE VI

                                  Compensation

         6.1 Inducement to Enter Agreement. As partial consideration, and as an
inducement to Physicians for entering this Agreement, PARTNERSHIP 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 Physicians or any of them.

         6.2 PARTNERSHIP's Risk. PARTNERSHIP 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. PARTNERSHIP 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, PARTNERSHIP is assuming responsibility for losses as
provided in Section 6.1. The parties therefore recognize and agree that in order
for PARTNERSHIP 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 PARTNERSHIP
should increase in future years.

         6.3 Professional Fees. Physicians shall, in consultation with
PARTNERSHIP, 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 Physicians. PARTNERSHIP, or its
delegate, shall serve as billing and collection agent for Physicians, and shall
be diligent and timely in the performance of billing and collection services.
However, PARTNERSHIP does not guarantee collection and shall not be responsible
for any loss to Physicians 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 Physicians shall be fairly and reasonably
compensated for their professional services and those of the physicians engaged
by them, and PARTNERSHIP 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 PARTNERSHIP system.

         6.6 Fair and Reasonable Compensation of Physicians. The parties hereto
agree Physicians will be fairly and reasonably compensated for their services
and those of the physicians it engages by retaining in the aggregate twenty-five
percent (25%) of the amount of money actually collected ("collected receipts")
by the Center for each medical imaging diagnostic or other


                                        7
   8
medical procedure ("medical services") performed at the Center. All collected
receipts for anything directly associated with the services of Physicians,
related to the Center, including charges for use of equipment, supplies,
facilities and assisting personnel shall be deemed to be for medical services
for purposes of this Agreement.

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

         6.8 Remittance. All monies which Physicians are entitled to retain
pursuant to Section 6.1 and all monies which PARTNERSHIP is entitled to receive
pursuant to Section 6.7 shall be accounted for and disbursed monthly.

         6.9. Advance. Beginning on the first day of the first calendar month
following the date on which the Center becomes fully operational (which the
parties shall fix by written agreement) and on the 1st day of each of the next
five calendar months (provided this Agreement has not otherwise been terminated)
PARTNERSHIP will pay to each of Joel and Keith as an advance against
compensation, which they are entitled to retain under Section 6.6 the sum of
$6,667.00. In any month when compensation to that individual exceeds $6,667.00,
the excess shall be paid to PARTNERSHIP until such time as all advances to said
individual have been repaid in full.

                                   ARTICLE VII

                              Term and Termination

         7.1 Term. This Agreement became effective on the date first above
written and shall continue for a period of at least six months thereafter, and
indefinitely thereafter until terminated.

         7.2 Termination. Either party may terminate this Agreement, with or
without cause, within the six-month period referred to in Section 7.1 by giving
the other party written notice of termination. This Agreement may be terminated
at any time by either party in the event of a material breach by the other party
to this Agreement, which is not cured by the breaching party within 60 days
after written notice of the breach has been given to the breaching party.

         7.3 Rights Upon Termination. The termination of this Agreement shall
not release or discharge either party from any obligation, debt or liability
which shall have previously accrued and remain to be performed upon the date of
termination, or which by its terms is to be performed after the date of
termination.

         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 ot eh 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:


   12
         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:


   13
                  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.


   14
         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.
