Dear Stockholders:

     A Special Meeting of Stockholders of Medical Resources, Inc. ("MRI") will
be held at The Sheraton New York Hotel, 811 7th Avenue (at 52nd Street), New
York, New York 10019, on August 30, 1996 at 10:00 a.m., New York City Time.

     At the Special Meeting, you will be asked to consider and vote upon an
Agreement and Plan of Merger dated May 20, 1996 (the "Merger Agreement"),
providing for the merger (the "Merger") of NMR of America, Inc. ("NMR") into a
wholly-owned subsidiary of MRI, pursuant to which NMR will become a wholly-owned
subsidiary of MRI, and each outstanding share of NMR Common Stock will
automatically be converted into 0.6875 of a share of MRI Common Stock and each
outstanding warrant, option, convertible debenture and other right to acquire
shares of NMR Common Stock will automatically be deemed exercisable or
convertible into shares of MRI Common Stock at a ratio of 0.6875 of a share of
MRI Common Stock for each share of NMR Common Stock which otherwise would have
been issuable had such warrants, options, debentures or other rights been
exercised in full immediately prior to the Merger.

     Pursuant to the terms of the Merger Agreement, MRI will be required to
issue shares of MRI Common Stock. Approval of such issuance by a majority of the
shares of MRI Common Stock present in person or represented by proxy and
entitled to vote at the Special Meeting is required by the rules of the National
Association of Securities Dealers, Inc., because shares of MRI Common Stock are
traded on the Nasdaq National Market and the number of shares proposed to be
issued in the Merger will exceed 20% of the issued and outstanding shares of MRI
Common Stock. The Merger is subject to the satisfaction of a number of
conditions, including, among others, approval of the Merger Agreement by the
requisite vote of MRI's and NMR's stockholders and the effectiveness of a
registration statement filed under the Securities Act of 1933, as amended,
relating to the shares of MRI Common Stock to be issued in the Merger.

     After careful consideration, the Board of Directors of MRI has unanimously
approved the Merger Agreement and recommends that you vote FOR the proposal
relating thereto.

     At the Special Meeting, you will also be asked to vote on an amendment to
MRI's Certificate of Incorporation which will increase the number of authorized
shares of MRI Common Stock from 20,000,000 to 50,000,000. Such amendment will
only be given effect if the Merger Agreement is approved and the Merger is
consummated. After careful consideration, the Board of Directors of MRI has
unanimously approved the amendment to the MRI Certificate of Incorporation and
recommends that you vote FOR the proposal relating thereto.

     In the material accompanying this letter, you will find a Notice of Special
Meeting of Stockholders, a Joint Proxy Statement/Prospectus relating to the
actions to be taken by MRI stockholders at the Special Meeting and a proxy card.
The Joint Proxy Statement/Prospectus more fully describes the proposed Merger
and other matters to be considered at the Special Meeting and includes certain
information concerning MRI and NMR. MRI's 1995 Annual Report to Stockholders and
its Quarterly Report on Form 10-Q for the three month period ended March 31,
1996 provide additional information concerning MRI and have also been included
herewith. In addition, NMR's 1996 Annual Report to Stockholders (which includes
NMR's Annual Report on Form 10-KSB for the fiscal year ended March 31, 1996),
which provides additional information concerning NMR is also enclosed herewith.

     All stockholders are cordially invited to attend the Special Meeting in
person. However, to assure your representation at the Special Meeting, you are
urged to complete, sign and return the enclosed proxy card as promptly as
possible in the postage prepaid envelope enclosed for that purpose. Any
stockholder attending the Special Meeting may revoke his or her proxy and vote
in person even if he or she has returned a proxy card. It is important that your
shares be represented and voted at the Special Meeting.

                                            Sincerely,

Dear Stockholders:

     The Annual Meeting of Stockholders of NMR of America, Inc. ("NMR") will be
held at The Sheraton New York Hotel, 811 7th Avenue (at 52nd Street), New York,
New York 10019, on August 30, 1996 at 10:00 a.m., New York City time.

MRI Common Stock for each share of NMR Common Stock which otherwise would have
been issuable had such warrants, options, debentures or other rights been
exercised in full immediately prior to the Merger.

     After careful consideration, the Board of Directors of NMR has unanimously
approved the Merger Agreement and recommends that you vote FOR the proposal
relating thereto.

    To account for the possibility that the Merger Agreement will not be
approved (either by the stockholders of NMR or the stockholders of MRI) or that
the Merger will not be consummated for any other reason, you will also be asked
to vote on the election of five (5) directors of NMR to hold office until the
next annual meeting of stockholders and until their successors are duly elected
and qualified. The vote on this matter will only be given effect if the Merger
Agreement is not approved or the Merger is not otherwise consummated.

    In the material accompanying this letter, you will find a Notice of Annual
Meeting of Stockholders, a Joint Proxy Statement/Prospectus relating to the
actions to be taken by NMR stockholders at the Annual Meeting and a proxy card.
The Joint Proxy Statement/Prospectus more fully describes the proposed Merger
and other matters to be considered at the Annual Meeting and includes certain

     NOTICE IS HEREBY GIVEN that the Annual Meeting (the "Annual Meeting") of
the Stockholders of NMR of America, Inc., a Delaware corporation ("NMR"), will

consider and act upon the following matters:

          1. ITEM NO. 1 IN THE ATTACHED JOINT PROXY STATEMENT/PROSPECTUS.
     Approval of an Agreement and Plan of Merger dated May 20, 1996 (the "Merger
     Agreement"), providing for the merger (the "Merger") of NMR into a
     wholly-owned subsidiary of Medical Resources, Inc. ("MRI"), pursuant to
     which NMR would become a wholly-owned subsidiary of MRI and each
     outstanding share of Common Stock, par value $0.01 per share, of NMR ("NMR

 PROXY STATEMENT/PROSPECTUS                               PROXY STATEMENT

                             MEDICAL RESOURCES, INC.

                  UP TO 5,643,673 SHARES OF MRI COMMON STOCK
                         TO BE ISSUED IN CONNECTION WITH
                            A MERGER TRANSACTION WITH
                              NMR OF AMERICA, INC.

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

                        JOINT PROXY STATEMENT/PROSPECTUS

     This Joint Proxy Statement/Prospectus (the "Joint Proxy
Statement/Prospectus") is being furnished to stockholders of Medical Resources,
Inc., a Delaware corporation ("MRI"), and stockholders of NMR of America, Inc.,
a Delaware corporation ("NMR"), in connection with a Special Meeting of
Stockholders of MRI and the Annual Meeting of Stockholders of NMR, to be held
for the purpose of considering and voting on an Agreement and Plan of Merger,
dated May 20, 1996 (the "Merger Agreement"), providing for the merger (the
"Merger") of NMR into a wholly-owned subsidiary of MRI, pursuant to which (i)
stockholders of NMR would receive shares of Common Stock, par value $0.01 per
share, of MRI ("MRI Common Stock") based on a ratio (the "Exchange Ratio") of
0.6875 of a share of MRI Common Stock for each outstanding share of the Common
Stock, par value $0.01 per share, of NMR ("NMR Common Stock"), and (ii) each
outstanding NMR warrant, option, convertible debenture and other right to
acquire shares of NMR Common Stock ("NMR Derivative Securities") would
automatically be deemed exercisable or convertible into shares of MRI Common
Stock at a ratio of 0.6875 of a share of MRI Common Stock for each share of NMR
Common Stock which otherwise would have been issuable had such NMR Derivative
Security been exercised or converted in full immediately prior to the Merger.
See "Terms of the Merger." The Exchange Ratio was determined as a result of
negotiations conducted between MRI and NMR, and was supported by fairness
opinions furnished to MRI's Board of Directors and a committee of independent
directors of NMR (the "NMR Special Committee"). See "The Merger--Background of
the Merger; Negotiations; Fairness Opinions." In the event the Merger is
consummated, following the Merger the stockholders of NMR will hold
approximately 38.9% of the issued and outstanding shares of MRI Common Stock
(assuming the exercise of all outstanding NMR Derivative Securities prior to the
consummation of the Merger).

    This Joint Proxy Statement/Prospectus also constitutes a Prospectus of MRI
under the Securities Act of 1933, as amended (the "Securities Act"), for the
issuance of, pursuant to the terms of the Merger Agreement, MRI Common Stock to
all holders of NMR Common Stock. This Joint Proxy Statement/Prospectus covers
only shares of MRI Common Stock issuable pursuant to the Merger to holders of
NMR Common Stock as of the date on which the Merger is consummated (the
"Effective Time") and does not cover the shares of MRI Common Stock which are
issued following consummation of the Merger to holders of NMR Derivative
Securities exercised following the Merger. The issuance by MRI of such shares of
MRI Common Stock upon exercise of any NMR Derivative Securities following
consummation of the Merger, and the subsequent resale thereof by the holders,
must be covered either by a separate registration statement or an applicable
exemption from the registration requirements under the Securities Act. MRI
intends to file a separate registration statement or registration statements
covering such shares promptly after the Effective Time.

    On July 29, 1996, the closing sales price per share on the Nasdaq National
Market for MRI Common Stockwas $7.38.

                 SUMMARY OF JOINT PROXY STATEMENT/PROSPECTUS

    The following is a brief summary of certain information contained elsewhere
in this Joint Proxy Statement/Prospectus. This summary does not contain a
complete statement of all material features of the matters to be voted upon and
is qualified in its entirety by reference to the more detailed information and
financial statements appearing elsewhere in this Joint Proxy
Statement/Prospectus and the documents incorporated by reference herein,
including the appendices to this Joint Proxy Statement/Prospectus.

THE COMPANIES

    Medical Resources, Inc. and MRI Sub, Inc. MRI, a Delaware corporation,
specializes in the operation and acquisition of diagnostic imaging centers and
the management of the associated physicians' practices. MRI operates and manages
free standing, outpatient diagnostic imaging centers, and provides diagnostic
imaging network management services to managed care providers. MRI provides
diagnostic imaging services through nineteen outpatient centers, of which it
owns all or a majority of the equity. The centers are located in New Jersey, New
York and Florida. MRI's centers service referring physicians and managed care
organizations by providing diagnostic imaging procedures to patients in a
comfortable, service-oriented environment located outside of an institutional
setting. At each of its centers, MRI provides management, administrative,
marketing and technical services, as well as equipment and facilities, to
physicians who interpret scans performed on patients referred by local
physicians. Medical services are provided by interpreting physicians, generally
board-certified radiologists, with whom MRI typically enters into long-term
contracts. All of MRI's centers provide magnetic resonance imaging, which
accounts for a majority of their revenues, with most also providing some or all
of the following services: computerized tomography, ultrasound, nuclear
medicine, general radiology and fluoroscopy and mammography.

    MRI also provides through its wholly-owned subsidiary, StarMed Staffing,
Inc. (hereinafter referred to as "StarMed"), temporary staffing of registered
nurses and other professional medical personnel to acute care and sub-acute care
facilities nationwide. StarMed offers services through two divisions: Travel
Nursing and Per Diem. Travel nursing describes a temporary staffing arrangement
under which a hospital contracts with StarMed to provide specialist nursing and
allied health staff for short periods (usually ranging from 8 to 26 weeks).
Temporary staff provided to the client are relocated from their place of
residence to the hospital location for the period of the assignment. MRI's per
diem staffing segment provides healthcare professionals for daily services to
both acute and sub-acute care facilities nationwide.

     MRI Sub, Inc. ("Subsidiary"), a Delaware corporation, is a wholly-owned
subsidiary of MRI formed solely for the purpose of effecting the Merger.

     MRI and Subsidiary have their principal executive offices at 155 State
Street, Hackensack, New Jersey 07601 (telephone: (201) 488-6230) and 2701 N.
Rocky Point Drive, Suite 650, Tampa, Florida 33607 (telephone: (813) 281-0202).

    NMR of America, Inc. NMR, a Delaware corporation, is engaged, directly and
through limited partnerships, in the business of installing, managing and
maintaining magnetic resonance imaging systems and other imaging systems used
for diagnostic purposes on an outpatient basis at eighteen imaging centers
located in the states of Florida, Illinois, Maryland, New Jersey and
Pennsylvania. Eleven of NMR's centers were developed by NMR and seven centers
were acquired by NMR from previous owners. At the eleven centers developed by
NMR, NMR has entered into agreements with an affiliated physician engaging in
business as professional associations ("Professional Associations") pursuant to
which NMR maintains and operates imaging systems in offices operated by the
Professional Associations. NMR purchases or leases the systems, supervises their
installation and staffs the facility with technical, clerical and marketing
personnel while the Professional Associations contract for radiological services
with local physicians and sublease each facility. At the seven centers which NMR
acquired, subsidiaries of NMR have entered into agreements directly with
unaffiliated professional corporations to provide radiological services and NMR
is responsible for all other aspects of the operation of the centers.

    The principal executive offices of NMR are located at 430 Mountain Avenue,
Murray Hill, New Jersey 07974 (telephone: (908) 665-9400).

August 30, 1996 at 10:00 a.m., New York City Time.

    MRI has fixed the close of business on July 29, 1996 as the record date for
determining holders of MRI Common Stock entitled to notice of and to vote at the
MRI Meeting. NMR has fixed the close of business on July 29, 1996 as the record
date for determining holders of NMR Common Stock entitled to notice of and to
vote at the NMR Meeting. See "Voting and Proxies."

PURPOSES OF THE MEETINGS

    The purpose of the MRI Meeting is to consider and vote upon proposals (i) to
approve the Merger Agreement (a conformed copy of which is attached as Appendix
A to this Joint Proxy Statement/Prospectus), pursuant to which NMR will be
merged with and into Subsidiary, resulting in NMR becoming a wholly-owned
subsidiary of MRI and to issue shares of MRI Common Stock in connection
therewith (ITEM No. 1) and (ii) to approve an amendment to MRI's Certificate of
Incorporation which will increase the number of authorized shares of MRI Common
Stock from 20,000,000 to 50,000,000 (ITEM No. 2). THE VOTE WITH RESPECT TO ITEM
NO. 2--RELATING TO MRI ONLY--WILL ONLY BE GIVEN EFFECT IF THE MERGER AGREEMENT
IS APPROVED AND THE MERGER IS CONSUMMATED.

    Pursuant to the terms of the Merger Agreement, MRI will be required to issue
shares of MRI Common Stock. Approval of such issuance by the stockholders of MRI
is required by the rules of the National Association of Securities Dealers,
Inc., because shares of MRI Common Stock are traded on the Nasdaq National
Market and the number of shares proposed to be issued in the Merger will exceed
20% of the issued and outstanding shares of MRI Common Stock.

    The purpose of the NMR Meeting is to consider and vote upon proposals (i) to
approve the Merger Agreement (ITEM No. 1) and, alternatively, (ii) to account
for the possibility that the Merger Agreement will not be approved (by either
the stockholders of NMR or the stockholders of MRI) or that the proposed Merger
will not be consummated for any other reason, to elect five (5) directors of NMR
to hold office until the next annual meeting of stockholders and their
successors are duly elected and qualified (ITEM No. 3). THE VOTE WITH RESPECT TO
ITEM NO. 3--RELATING TO NMR ONLY--WILL ONLY BE GIVEN EFFECT IF THE MERGER
AGREEMENT IS NOT APPROVED OR THE MERGER IS NOT OTHERWISE CONSUMMATED.

VOTES REQUIRED

    MRI. The affirmative vote of a majority of the shares of MRI Common Stock
present in person or represented by proxy and entitled to vote at the MRI
Meeting is required to approve the Merger Agreement and issuance of the MRI
Common Stock pursuant to the Merger (ITEM No. 1). As of the date hereof,
directors and executive officers of MRI beneficially own approximately 32.2% of
the outstanding shares of MRI Common Stock (excluding shares issuable upon
exercise of outstanding MRI options and warrants or conversion of convertible
debentures held by such persons). Such directors and executive officers of MRI
intend to vote all shares of MRI Common Stock beneficially owned by them in
favor of approval of the Merger Agreement. See "Information Concerning Medical
Resources, Inc.--Ownership of MRI Common Stock."

    With respect to ITEM No. 2, the affirmative vote of the holders of a
majority of the outstanding shares of MRI Common Stock is required to approve
the amendment to MRI's Certificate of Incorporation (ITEM No. 2).

    NMR. The affirmative vote of the holders of a majority of the outstanding
shares of NMR Common Stock is required to approve the Merger Agreement (ITEM No.
1). As of the date hereof, directors and executive officers of NMR beneficially
own approximately 5.2% of the outstanding shares of NMR Common Stock (excluding
shares issuable upon exercise of NMR Derivative Securities held by such
persons). Such directors and executive officers of NMR intend to vote all shares
of NMR Common Stock beneficially owned by them in favor of approval of the
Merger Agreement. See "Information Concerning NMR of America, Inc.--Principal
and Other Stockholders of NMR."

     With respect to ITEM No. 3, which will only be given effect if the Merger
Agreement is not approved (by either the stockholders of NMR or the stockholders
of MRI) or if the Merger is not otherwise consummated, the directors of NMR will

the NMR Meeting in person or represented by proxy. See "Voting and Proxies."

    The remainder of this summary of the Joint Proxy Statement/Prospectus
summarizes certain information concerning the Merger and sets forth certain
selected financial information with respect to MRI and NMR.

RECOMMENDATIONS OF BOARD OF DIRECTORS

    The Board of Directors of MRI has unanimously approved the Merger Agreement,
and has adopted resolutions recommending that the stockholders of MRI vote FOR
approval of the Merger Agreement. The Board of Directors of NMR has unanimously
approved the Merger Agreement, and has adopted resolutions recommending that the
stockholders of NMR vote FOR approval of the Merger Agreement.

    The respective directors of MRI and NMR believe that the Merger is in the
best interests of the stockholders of MRI and NMR, respectively. The actions and
recommendations of the Boards of Directors of MRI and NMR in connection with the
Merger are based upon a number of factors discussed in this Joint Proxy
Statement/Prospectus. See "The Merger--Background of the Merger; Negotiations;
Fairness Opinions" and "The Merger--MRI's Reasons for the Merger; NMR's Reasons
for the Merger." In approving the Merger Agreement, certain members of the Board
of Directors of NMR and MRI may be deemed to have certain conflicts of interest.
See "Terms of the Merger--Interest of Certain Persons in the Merger."

    The Board of Directors of MRI has also unanimously approved a proposal to
amend MRI's Certificate of Incorporation in order to increase the number of
authorized shares of MRI Common Stock from 20,000,000 to 50,000,000 (ITEM No.
2), and recommends a vote FOR approval of this proposal.

    In the event the Merger Agreement is not approved by the stockholders of
NMR, or the Merger is not otherwise consummated, the Board of Directors of NMR
has also unanimously nominated for election as directors of NMR the five
nominees listed in ITEM No. 3.

INTEREST OF CERTAIN PERSONS IN THE MERGER

    In considering the recommendations of the MRI and NMR Boards of Directors
with respect to the Merger Agreement, stockholders should be aware that certain
members of NMR management have certain interests in the Merger that are in
addition to the interests of stockholders of NMR generally. Such executives of
NMR will be entitled to certain payments upon consummation of the Merger
pursuant to termination agreements and non-competition and consulting agreements
which have heretofore been executed and are conditioned upon consummation of the
Merger. See "Terms of the Merger--Non-Competition and Consulting Agreements." An
affiliate of the Chairman of the Board of Directors of MRI which has provided
and will continue to provide significant financial advice to MRI in connection
with the Merger will receive a financial advisory fee in the event that the
Merger is consummated. See "Terms of the Merger--Interest of Certain Persons in
the Merger."

FAIRNESS OPINIONS

    Dillon, Read & Co. Inc. ("Dillon Read") has rendered its written opinion to
the Board of Directors of MRI to the effect that the consideration (referred to
in the Merger Agreement and herein as the Exchange Ratio) to be paid by MRI in
the Merger is fair to MRI from a financial point of view. A copy of such opinion
is attached as Appendix B to this Joint Proxy Statement/Prospectus. On June 13,
1996, Cowen & Company ("Cowen") rendered its written opinion to the NMR Special
Committee to the effect that, as of such date, the proposed Exchange Ratio was
fair, from a financial point of view, to the holders of the outstanding shares
of NMR Common Stock. A copy of such opinion is attached as Appendix C to this
Joint Proxy Statement/Prospectus. See "The Merger--Fairness Opinion of Dillon
Read; Fairness Opinion of Cowen."

Stock and NMR Common Stock should consider certain risk factors relevant to the

include, but are not limited to, (i) the liquidity needs and significant
long-term indebtedness of MRI and NMR, (ii) recent losses, (iii) certain
reimbursement and collection risks relating to the healthcare industry, (iv)
extensive government regulation (including the effects of possible federal and

PRINCIPAL TERMS OF THE MERGER

    The Merger Agreement, a conformed copy of which (without exhibits and
schedules) is attached hereto as Appendix A, provides that, upon consummation of
the Merger, NMR will be merged with and into Subsidiary, NMR's corporate
existence will terminate, and Subsidiary, the surviving corporation, will be a
wholly-owned subsidiary of MRI. Upon consummation of the Merger, holders of
shares of NMR Common Stock, will receive shares of MRI Common Stock based on the
Exchange Ratio of 0.6875 of a share of MRI Common Stock for each issued and
outstanding share of NMR Common Stock. The Exchange Ratio was determined as a
result of negotiations conducted between MRI's Board of Directors and the NMR
Special Committee and the respective managements of MRI and NMR, and was
addressed in the written financial fairness opinions of Dillon Read and Cowen.
See "Terms of the Merger--Conversion of Shares; Treatment of Options, Warrants,
Convertible Debentures and Other Rights; Fractional Shares" and "The
Merger--Background of the Merger; Negotiations; Fairness Opinions."

    The Merger Agreement provides that each outstanding NMR Derivative Security
will remain outstanding and will be exercisable for or convertible into that
number of shares of MRI Common Stock the holder thereof would have received in
the Merger had such holder exercised or converted such NMR Derivative Security
in full immediately prior to the Effective Time, and that the exercise price
thereof shall be appropriately adjusted. See "Terms of the Merger--Conversion of
Shares; Treatment of Options, Warrants, Convertible Debentures and Other Rights;
Fractional Shares."

    The Merger Agreement provides that consummation of the Merger is subject to
certain terms and conditions, including the approval of the Merger Agreement by
the stockholders of MRI and NMR. The Merger Agreement also provides that
consummation of the Merger is conditioned upon MRI, NMR and Subsidiary obtaining
all necessary consents and approvals to the consummation of the Merger. See
"Terms of the Merger--Conditions Precedent to Consummation of the Merger." Other
than in connection with this Joint Proxy Statement/Prospectus and the
registration of the MRI Common Stock, no Federal or state regulatory
requirements must be complied with or approval must be obtained in connection
with the Merger other than such as has already been obtained.

    The Merger Agreement provides that the obligations of MRI and NMR are
subject to the performance in all material respects, unless otherwise waived, of
their respective covenants and agreements set forth in the Merger Agreement and
the continued truth in all material respects of their respective representations
and warranties set forth in the Merger Agreement. There are no agreements or
undertakings in the Merger Agreement on the part of either MRI or NMR to
indemnify the other following consummation of the Merger in the event any
representation or warranty made by either party to the other in the Merger
Agreement was not accurate at the time made.

     Mr. Joseph G. Dasti, Chairman of the Board of Directors and President and
Chief Executive Officer of NMR, and Mr. John P. O'Malley III, Executive Vice
President-Finance, Chief Financial Officer and Secretary of NMR, have entered
into respective non-competition and consulting agreements with MRI, the
effectiveness of which are conditioned upon the consummation of the Merger. See
"Terms of the Merger--Non-Competition and Consulting Agreements; Interest of
Certain Persons in the Merger."

    The Merger Agreement may be terminated by the mutual written consent of the
Boards of Directors of MRI and NMR at any time prior to the Effective Time of
the Merger and by either party (i) if the Merger Agreement is not approved by
the stockholders of MRI at the MRI Meeting or by the stockholders of NMR at the
NMR Meeting, (ii) if the Effective Time has not occurred on or before December
31, 1996 through no fault of the terminating party, (iii) if the Merger is
enjoined or prohibited by a court or governmental agency, or (iv) in certain
other circumstances. See "Terms of the Merger--Termination and Amendment." Under
certain circumstances, if either MRI or NMR breaches certain representations,
warranties or covenants, it would be required to pay to the other party a fee in
the amount of $2,000,000. If the stockholders of either NMR or MRI do not
approve the Merger, the party whose

stockholders do not approve the Merger will be required to pay to the other
$1,000,000. See "Terms of the Merger--Expenses of the Merger; Fees; No
Solicitation Provision and Fee Payable."

    The Merger Agreement provides that, as soon as practicable following the
fulfillment of all conditions to the Merger, including the approval of the
Merger Agreement by the stockholders of MRI and by the stockholders of NMR, a
Certificate of Merger will be filed with the Delaware Secretary of State. The
Merger will become effective upon filing the Certificate of Merger with the
Delaware Secretary of State. The current executive officers and directors of MRI
are expected to continue as executive officers and directors of MRI following
the Merger.

                       RISK FACTORS REGARDING MRI AND NMR

    In addition to the other information contained or?incorporated by reference
in this Joint Proxy Statement/Prospectus, holders of shares of MRI Common Stock
and NMR Common Stock should carefully consider the factors set forth below which
relate to MRI and NMR (collectively, the "Companies") before voting with respect
to the Merger.

    CAPITAL NEEDS. MRI's required capital expenditures and planned operating
expenses are anticipated to be financed by a combination of operating cash flow,
funds available through working capital and third party credit facilities. There
may be circumstances, however, such as additional acquisitions, that could
accelerate MRI's use of cash. If this occurs, MRI may incur, from time to time,
additional indebtedness and attempt to issue, in public or private transactions,
equity and debt securities. There can be no assurance that MRI will have access
to additional financing on satisfactory terms and the inability to obtain
additional capital would have a material adverse effect on MRI's ability to
expand its business.

    RECENT LOSSES. Both MRI and NMR were profitable during their last fiscal
year. Although MRI realized net income of approximately $1,690,000 for the year
ended December 31, 1995, it incurred net losses of $1,994,000 for the fiscal
year ended December 31, 1994 and $2,797,000 for the fiscal year ended December
31, 1993. Moreover, the Companies obtain a substantial portion of their business
from patients who are members or enrollees of various managed care health plans,
and it is anticipated that this portion of the Companies' business will increase
in the future. Due to the ability of these third-party payers to obtain
substantial discounts from healthcare providers such as MRI and NMR, the
continued growth in both the size and number of managed care entities will
increase price competition and may have a negative impact on the revenues,
operating margins and profitability of companies operating in the diagnostic
imaging industry. In addition, in recent years, many of the public companies
operating in the diagnostic imaging business have reported substantial operating
losses. There can be no assurance that the Companies will operate profitably in
the future.

    SIGNIFICANT LONG-TERM DEBT, INCLUDING CAPITALIZED LEASE OBLIGATIONS. Both
MRI and NMR have significant outstanding debt comprised principally of
capitalized lease obligations relating to equipment at their centers. At March
31, 1996, MRI's long-term debt, excluding current maturities, was approximately
$23,334,000, of which capitalized lease indebtedness was approximately
$7,841,000. NMR's long-term debt, excluding current maturities, was $14,156,854
at March 31, 1996, of which capitalized lease and loan indebtedness was
$1,152,455. MRI and NMR have financed the acquisition of substantially all of
the diagnostic imaging equipment used at their centers (typically with terms
ranging from five to seven years) from lenders and lessors, with the equipment
and other assets serving as collateral for the loans. Substantially all of the
Companies' assets have been pledged as collateral for their respective
obligations. In MRI's case, generally, the center leasing the equipment and the
subsidiary which operates the center are the only obligors under each such
lease. NMR has guaranteed certain obligations of its subsidiaries. At March 31,
1996, the ratios of total liabilities to stockholders' equity of MRI and NMR
were 1.92 to 1.00 and 1.24:1.00, respectively. At March 31, 1996, after giving
effect to the Merger on a pro-forma combined basis, the ratio of MRI's total
liabilities to stockholders' equity would have been 1.14 to 1.00. A default
under an equipment lease of MRI or NMR could materially adversely affect the
operations of the applicable center and, consequently, the results of operations
of MRI or NMR.

    In addition, following the Merger, MRI may incur additional indebtedness for
future expansion and equipment replacements and upgrades. MRI is subject to the
risks associated with such indebtedness, including the risk that its cash flow
may not be adequate to make required payments on indebtedness. A decrease in
reimbursements for diagnostic imaging services or in equipment utilization
arising from, among other things, cancellation or non-renewal of provider
contracts, equipment malfunctions, the inability to effect prompt and timely
repairs to equipment or a reduction in demand for MRI's equipment or services
could materially and adversely effect MRI's ability to service its indebtedness
following the Merger. In addition, the high ratio of indebtedness to
stockholders' equity to which MRI will be subject following the Merger, may
restrict or impair MRI's ability to make additional acquisitions or exploit
future business opportunities. See "MRI and NMR Unaudited Pro Forma Combined
Financial Statements"; "Risk Factors Regarding MRI and NMR--Capital Needs;
Limitations and Delays in Reimbursement; Acquisition and Development Strategy."

    LIMITATIONS AND DELAYS IN REIMBURSEMENT. Third-party payors, including
Medicare, Medicaid, managed care/HMO providers and certain commercial payors
have taken extensive steps to contain or reduce the costs of health 


                                       16


<PAGE>


care. In certain areas, the payors are subject to regulations which limit the
amount of payments. Current discussions within the federal government regarding
national health care reform are emphasizing containment of health care costs. In
addition, certain managed care organizations have negotiated capitated payment
arrangements for imaging services. Under capitation, diagnostic imaging service
providers are compensated using a fixed rate per member of the managed care
organization regardless of the total cost of rendering diagnostic services to
the members. Services provided under these contracts are expected to become an
increasingly significant part of the Companies' business. Although patients are
ultimately responsible for payment for services rendered, substantially all of
the Companies' imaging centers' revenues are derived from third-party payors.
Successful reduction of reimbursement amounts and rates, changes in services
covered, delays or denials of reimbursement claims, negotiated or discounted
pricing and other similar measures could materially adversely affect the
Companies' respective imaging centers' revenues, profitability and cash flow.

    The Companies' managements believe that reimbursement rates will continue to
decline due to factors such as the expansion of managed care providers and
continued national healthcare reform efforts. The Companies enter into
contractual arrangements with managed care organizations which, due to the size
of their membership, are able to command reduced rates for services. These
agreements may increase the number of procedures performed due to the additional
referrals from these managed care arrangements. However, there can be no
assurance that the increased volume of procedures associated with these
contractual arrangements will offset the reduced revenue resulting from the
reduction in reimbursement rate per procedure.

    In addition, during 1995 approximately 21.8% and 2.0%, respectively, of
MRI's and NMR's total revenues from third-party payors were derived through
physicians providing imaging services to patients involved in personal injury
claims. Receivables relating to personal injury claims require more extensive
documentation than other procedures. In addition, those individuals with
obligations to the Companies in excess of insurance coverage or who do not have
insurance coverage tend to delay payment until the legal action is resolved,
which may result in significant collection delays. Due to the greater complexity
in processing, as well as increased information requirements from third-party
payors, receivables relating to personal injury claims typically require a
longer period of time to collect compared to other receivables and, in the
experience of MRI, incur a higher bad debt expense.

    RESTRICTIONS IMPOSED BY GOVERNMENT REGULATION. The health care industry is
highly regulated. The ownership, operation and acquisition of outpatient
diagnostic centers are subject to various federal and state laws, regulations
and approvals concerning such matters as physician referrals, licensing of
facilities and personnel, and Certificates of Need for certain types of health
care facilities and major medical equipment. Among other penalties, violations
of these laws can result in the shutdown of a company's facilities and loss of
Medicare and Medicaid reimbursement. The Federal Anti-Kickback law prohibits the
offer, payment, solicitation or receipt of any form of remuneration in return
for referring Medicare or Medicaid patients or purchasing, leasing, ordering or
arranging for any item or service that is covered by Medicare or Medicaid. The
law provides several penalties for engaging in prohibited acts, including
criminal sanctions and exclusion from the Medicare and Medicaid programs.
Although the Companies do not believe that they are operating in violation of
this law, the scope of the law remains somewhat unclear and there is no
assurance that the Companies would prevail in their positions. In addition, in
1991 and subsequently, the Office of the Inspector General of the Department of
Health and Human Services promulgated "safe harbor" regulations specifying
activities that will be protected from criminal and civil investigation and
prosecution under the Federal Anti-Kickback law. Although the Companies believe
their operations generally qualify for protection under these regulations, the
regulations have thus far been relatively untested in practice, and there is no
assurance that the Companies will prevail in their positions. The Office of the
Inspector General has stated that failure to satisfy the conditions of an
applicable "safe harbor" does not necessarily indicate that the arrangement in
question violates the Federal Anti-Kickback law, but means that the arrangement
is not among those that the "safe harbor" regulations protect from criminal and
civil investigation and prosecution under that law. The finding of a violation
must still be determined based upon the precise language of the Federal
Anti-Kickback law.

    The Federal Budget Omnibus Reconciliation Act of 1989 contains provisions
that, unless an exception applies, restrict physicians from making referrals to
clinical laboratory facilities for services to be rendered to Medicare patients
in which the physicians have an ownership interest or with which they have a
compensation arrangement (the so-called "Stark I Legislation"). The Federal
Omnibus Budget Reconciliation Act of 1993 added provisions to these restrictions
on Medicare payment for physician referrals which, effective January 1, 1995,
greatly broadened the services which are subject to this referral and payment
ban (the so-called "Stark II Legislation"). Specifically with 


                                       17


<PAGE>


regard to the Companies' operations, the Stark II Legislation adds the referral
restriction to radiology or other diagnostic services. The Stark II Legislation
also extends these prohibitions to referrals of Medicaid patients. Both the
Stark I and the Stark II Legislation provide exceptions for certain types of
employment and contractual relationships. The Companies believe that they are in
compliance with the Stark II legislation but there is no assurance that their
position will not be challenged.

    The State of Florida also enacted in 1992 an anti-kickback statute
substantially similar in scope to the Federal Anti-Kickback law. Although the
Companies do not believe that they are operating in violation of this law, as
with its federal counterpart, the scope of the Florida law remains unclear and
there is no assurance that the Companies would prevail in their positions.

    The States of Florida, Illinois, New Jersey, New York and Pennsylvania have
enacted laws that restrict or prohibit physicians from referring patients to
health care facilities in which such physicians have a financial interest.
Although the Companies do not believe that these laws will have a material
adverse effect on their operations in these states, there is no assurance that
these laws will not be interpreted or applied in such a way as to create such a
material adverse effect, or that these states, or other states in which the
Companies do business, will not adopt similar or more restrictive laws or
regulations that could have such a material adverse effect.

    Certain states where MRI and NMR have imaging centers have enacted
certificate of need laws to facilitate healthcare planning by placing
limitations on the purchase of major medical equipment and other capital
expenditures. These statutes, together with their implementing regulations,
could limit MRI's and NMR's ability to acquire new imaging equipment or expand
or replace its existing equipment, and no assurances can be given that the
required regulatory approvals for any future acquisitions, expansions or
replacements will be granted to MRI or NMR.

    The Companies continually monitor regulatory initiatives at the federal and
state levels. New laws or regulations, changes in current laws or regulations or
changes in interpretations of current laws or regulations could have a material
adverse effect on the Companies. In addition, the cost of complying with the
foregoing could materially adversely affect the Companies' financial condition.
See "Government Regulation of MRI and NMR."

    POTENTIAL ADVERSE EFFECTS OF NATIONAL HEALTHCARE REFORM. Many aspects of the
medical industry in the United States are presently subject to extensive Federal
and state governmental regulation, including reimbursement rates and policies
imposed by Medicare and other third-party reimbursement programs from which MRI
and NMR receive a substantial portion of their revenue. Although healthcare
reform, if enacted following the Merger, may have the beneficial effect of
increasing the number of persons who will have access to services provided by
MRI and NMR, such reform may also reduce the fees that may be charged for such
services. In particular, there is a possibility that a significant portion of
healthcare services will be rendered and administered through a system which
could force price concessions from service providers such as MRI and NMR.
Moreover, healthcare reform could cause greater analysis of each patient's need
for diagnostic testing, with the aim of eliminating unnecessary tests and
reducing the volume and cost of medical care. Depending on the nature and extent
of any new laws and/or regulations, or possible changes in the interpretation of
existing laws and/or regulations, the foregoing may have a material adverse
effect on MRI's and NMR's revenues, operating margins and profitability.

    INTEGRATION OF ACQUIRED BUSINESS; MANAGEMENT OF GROWTH. The integration of
MRI's and NMR's respective operations following the Merger will require the
dedication of management resources which will temporarily detract from attention
to the day-to-day business of the combined company. The combination of the two
Companies will also require integration of the Companies' sales and marketing
efforts. The process of combining the two organizations may cause an
interruption of, or a loss of momentum in, the activities of either or both of
the Companies' businesses, which could have an adverse effect on the revenues
and operating results of the combined company, at least in the near term. There
can be no assurance that the combined entity will be able to retain its key
technical and management personnel or that the combined entity will realize any
of the other anticipated benefits of the Merger. In addition, the combined
company's ability to manage its growth effectively will require it to continue
to improve its operational, financial and information management systems and
controls, and to attract, retain, motivate and manage employees effectively. The
failure of the combined company to manage growth in its business effectively
would have a material adverse effect on its results of operations.

    COMPETITION. The outpatient diagnostic imaging industry is highly
competitive. Competition focuses primarily on attracting physician referrals,
including referrals through relationships with managed care organizations, at
the local market level. The Companies believe that principal competitors in each
of their markets are 


                                       18


<PAGE>


hospitals and independent or management-company-owned imaging centers, some of
which are owned with physician investors. Some of these competitors have greater
financial and other resources than MRI and NMR. Principal competitive factors
include quality and timeliness of test results, ability to develop and maintain
relationships with referring physicians, type and quality of equipment, facility
location, convenience of scheduling and availability of patient appointment
times, and the quality and convenience of facilities. Competition for physician
referrals can also be affected by the ownership or affiliation of competing
centers or hospitals, with certain of the Companies$ competitors having
historically derived a significant portion of their revenues from referrals by
physicians who are also investors and have a financial interest in, or are
otherwise affiliated with, the competing center or hospital. In addition,
managed care has affected the availability of referrals by approving only a
certain number of centers in a given geographic region.

    The healthcare temporary staffing business is also very competitive. StarMed
competes for clients' business with other providers of travel nurse temporary
staffing and with other staffing companies that provide per diem staffing
services. StarMed also competes for the limited number of available qualified
staff. Within the travel nurse segment of the temporary staffing industry,
StarMed competes with several companies which are larger and may possess greater
financial and other resources.

    DEPENDENCE ON REFERRING PHYSICIANS. At each of the Companies' imaging
centers, certain physicians, in private practice or affiliated with managed care
organizations, refer a significant percentage of such centers' patients. A
significant reduction by any such physician in the number of patients referred
to that center could materially adversely affect such center, and consequently,
following the Merger, the combined company's operating results.

    ACQUISITION AND DEVELOPMENT STRATEGY. MRI's current growth strategy focuses
primarily on acquiring existing imaging centers and healthcare temporary
staffing businesses and integrating them into its operations. With respect to
such acquisitions, there can be no assurance that suitable acquisition
candidates can be found, that acquisitions can be negotiated on acceptable
terms, that necessary financing can be obtained or that the operations of the
acquired businesses can be effectively or profitably integrated into MRI's
existing operations. Competition for suitable acquisition candidates is expected
to be intense and, in addition to local hospital and physician groups, to
include regional and national diagnostic imaging service companies and other
medical services companies, many of which have greater financial resources than
the Companies. MRI may also pursue the development of new centers. New centers
may incur significant operating losses, during their development stages, and
could materially adversely affect MRI's operating results and financial
condition. In addition, there can be no assurance that qualified executives who
may be required to manage such acquired operations can be successfully retained
or employed by MRI.

    TECHNOLOGICAL OBSOLESCENCE. There have been rapid technological advancements
made in the software and, to a lesser extent, hardware in the diagnostic imaging
industry. Although the Companies believe that their equipment can generally be
upgraded as necessary, the development of new technologies or refinements of
existing technologies might make existing equipment technologically or
economically obsolete. If such obsolescence were to occur, the Companies might
be compelled to purchase new equipment, which could have a material adverse
effect on their earnings and cash flow. In addition, certain of the Companies'
centers compete against local centers which contain more advanced imaging
equipment or provide additional modalities.

    LIABILITY CLAIMS AND INSURANCE. Although MRI and NMR provide technical
services and are not engaged in the practice of medicine, the diagnostic imaging
and temporary staffing businesses entail the risk of professional liability
claims. The Companies' exposure to such liability is reduced for their imaging
centers because interpreting physicians are required to carry their own medical
malpractice insurance. Similarly, MRI's nursing personnel perform services in
accordance with treatments prescribed by third-party physicians or under
hospital supervision. Nevertheless, the Companies maintain general liability
insurance and professional liability insurance for their diagnostic imaging
businesses and MRI carries general liability insurance and professional
liability insurance for its temporary staffing business in amounts deemed
adequate by the managements of the respective Companies. However, there can be
no assurance that potential claims will not exceed the coverage limits or that,
in the future, such insurance will be available.

    ANTICIPATED LOSSES FROM CERTAIN CENTERS. In November 1991 and May 1992, NMR
commenced operations of centers in Bel Air, Maryland and Elgin, Illinois,
respectively. To date, these centers have generated significant losses. For the
year ended March 31, 1996, NMR incurred net losses amounting to approximately
$359,313 and $135,584, respectively, relating to the operations of the Bel Air,
Maryland and Elgin, Illinois centers. In addition to 


                                       19


<PAGE>


NMR's initial capital contributions, NMR has made and continues to advance
working capital to fund the operations of these centers and cannot determine if
or when these centers will become profitable, or if or when these advances will
be repaid. As of March 31, 1996, the amount of working capital advances,
including accrued but unpaid interest thereon, made to each of the Bel Air,
Maryland and Elgin, Illinois centers by NMR amounted to approximately $2,933,731
and $1,862,998, respectively. If the Merger is consummated, MRI presently
expects that it will close these centers due to anticipated future operating
losses at such centers. MRI expects to incur a loss of approximately $1.6
million as a result of the closing of such centers, although there can be no
assurance of the timing of such closures or that the actual loss will not exceed
such amount.

    POTENTIAL ADVERSE EFFECT OF RESTRICTIONS ON UNLICENSED PRACTICE OF MEDICINE.
Diagnostic imaging centers are subject to laws prohibiting the practice of
medicine by non-physicians and the rebate or division of fees between physicians
and non-physicians. Professional radiology services are performed at MRI's and
NMR's centers by licensed physicians under contract with a medical professional
corporation, while MRI and NMR provide the imaging equipment and technical
employees. Although the Companies believe they are in compliance with relevant
existing laws, there can be no assurance that state authorities or others may
not challenge this structure as involving MRI or NMR in the unlawful practice of
medicine.

    DEPENDENCE ON QUALIFIED INTERPRETING PHYSICIANS. MRI's and NMR's strategy of
maintaining the high quality of their services is dependent upon their ability
to obtain and maintain arrangements with qualified interpreting physicians at
each of their centers. Following the Merger, no assurance can be given that the
Companies' contractual arrangements with interpreting physician groups at each
of the Companies' centers can be maintained on terms advantageous to the
Companies. No assurance can be given that the interpreting physicians with whom
MRI or NMR have contracts will perform satisfactorily or continue to practice in
the markets served by their imaging centers. In addition, with respect to the
development of new centers, there can be no assurance that arrangements can be
entered into with interpreting physicians on acceptable terms or that such
physicians will be successful in such centers. The Companies' success is
significantly dependent on the ability of these physicians to attract patient
referrals, thereby enabling the Companies' centers to operate profitably. The
inability of these physicians to attract sufficient referrals could have a
material adverse effect on the Companies' financial condition and operating
results.

    POTENTIAL CONFLICT OF INTEREST RESULTING FROM FIDUCIARY AND CONTRACTUAL
DUTIES OWED BY THE COMPANIES TO LIMITED PARTNERSHIPS. As managing general
partners in certain limited partnerships which own and operate diagnostic
imaging systems, the Companies or their wholly-owned subsidiaries are subject to
certain fiduciary and contractual duties owing to the other partners in these
limited partnerships, the breach of which would expose NMR, MRI or such
subsidiary to the risk of litigation and significant financial liabilities.
Generally, as general partner, each of the Companies or their respective
subsidiary owe fiduciary duties of care and loyalty to the other partners in
these partnerships. The interests of the Companies and their respective
stockholders may not always coincide with the interests of the Companies'
partners in such partnerships, and the Companies' fiduciary duties may prevent
the Companies from taking certain actions with respect to these partnerships
which, while beneficial to the Companies, would be detrimental to other
partners. The duty of loyalty may also prevent the Companies from taking
advantage of business opportunities which may be available to one of their
respective partnerships.

    The Companies' contractual duties include obligations to obtain partners'
consents to perform various acts, such as obtaining financing for upgrades and
equipment replacements and sales of significant partnership assets. Accordingly,
the other partners in such centers may prevent the partnerships from taking
certain actions which the Companies may deem beneficial to them and their
stockholders.

    INFLUENCE BY AFFILIATES OF SIEGLER, COLLERY & CO. As of July 1, 1996,
affiliates of Siegler, Collery & Co., a New?York-based investment firm,
beneficially owned approximately 33.0% of the issued and outstanding shares of
MRI Common Stock (excluding shares issuable pursuant to options, warrants or
other rights to purchase shares of MRI Common Stock). Gary N. Siegler and Peter
M. Collery, Chairman of the Board and a former director of MRI, respectively,
control each of these affiliates. As a result of such ownership, Messrs. Siegler
and Collery have the ability to influence MRI's policies, the election of
directors and the authorization of certain transactions that require stockholder
approval. Immediately following the Merger, Messrs. Siegler and Collery, through
such affiliates, will own approximately 22.2% of the issued and outstanding
shares of MRI Common Stock.

    SHARES AVAILABLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT OF OUTSTANDING
DERIVATIVE SECURITIES. Following the Merger, there will be approximately
9,316,794 shares of MRI Common Stock held by members of the 


                                       20


<PAGE>


public that are able to trade without restriction (assuming no exercise or
conversion of outstanding NMR Derivative Securities or outstanding options,
warrants or convertible securities of MRI ("MRI Derivative Securities") prior to
the Effective Time). In addition, following the Merger, an additional 1,305,156
shares of MRI Common Stock will be issuable upon exercise or conversion of NMR
Derivative Securities and 2,819,625 shares of MRI Common Stock will be issuable
upon exercise or conversion of presently outstanding MRI Derivative Securities,
of which 2,699,625 shares have been registered by MRI for resale under the
Securities Act. In connection with the Merger, MRI has agreed to register for
resale the shares of MRI Common Stock issuable upon exercise of the NMR
Derivative Securities. Upon such registration, these shares not held by
affiliates of NMR will become freely tradeable and transferable without
restriction. The exercise or conversion of a substantial amount of these
securities could adversely affect the market price of MRI Common Stock due to
the large number of shares issuable upon exercise or conversion of such
securities. In addition, so long as such securities remain outstanding, the
market price of MRI Common Stock and the terms under which MRI might obtain
additional equity capital may be materially and adversely affected. Any sales of
substantial amounts of MRI Common Stock in the open market could have a material
adverse effect on the market price of the MRI Common Stock. No prediction can be
made as to the effect, if any, that the issuance of shares of MRI Common Stock
in the Merger or sales of shares of MRI Common Stock or the availability of such
shares for future sale will have on the market prices prevailing from time to
time. The possibility that substantial amounts of MRI Common Stock may be sold
in the public market may adversely affect prevailing market prices and,
therefore, could impair MRI's ability to raise capital through the sale of
equity securities. See "Description of MRI Capital Stock--Shares Eligible for
Future Sale."

    MRI has also granted to holders of 958,571 shares of MRI Common Stock
certain rights to have the resale of such shares registered under the Securities
Act. In the event these registration rights are exercised, these shares would
become freely tradable and transferable without restriction. Exercise of any
such registration rights will require MRI to incur the expense of registering
such securities and may hinder efforts by MRI to arrange future financing and
have a material adverse effect on the market price of MRI Common Stock.

    ABSENCE OF DIVIDENDS. MRI has no present plans to pay cash dividends to its
stockholders and, for the foreseeable future, intends to retain all of its
earnings, if any, for use in its business. The declaration of any future
dividends by MRI is within the discretion of its Board of Directors and will be
dependent on the earnings, financial condition and capital requirements of MRI,
as well as any other factors deemed relevant by its Board of Directors.

    POSSIBLE ADVERSE EFFECTS OF PREFERRED STOCK ISSUANCES. MRI's Certificate of
Incorporation authorizes the issuance of 100,000 shares of preferred stock with
such rights, preferences and privileges as may be determined by the Board of
Directors of MRI. Accordingly, the Board of Directors has the power, without
prior stockholder approval, to issue series of preferred stock with such
dividend rights, redemption provisions, liquidation preferences, voting rights,
conversion privileges and other characteristics as the MRI Board may deem
appropriate. The issuance of the preferred stock could have a material adverse
effect on the rights of holders of MRI Common Stock. In addition, the preferred
stock could be issued to discourage, delay or prevent an attempted takeover of
MRI, and could enhance the ability of directors of MRI to retain their
positions. See "Description of MRI Capital Stock--Preferred Stock."

    VOLATILITY OF STOCK PRICE. MRI Common Stock trades on the Nasdaq National
Market. The market price of the MRI Common Stock has been and may continue to be
volatile. Recently, the stock market in general and the shares of healthcare or
diagnostic imaging services companies in particular have experienced significant
price fluctuations. These broad market and industry fluctuations may adversely
affect the market price of MRI Common Stock. Factors such as quarterly
fluctuations in results of operations and general conditions in the healthcare
industry may have a significant impact on the market price of MRI Common Stock.
There can be no assurance as to the effect of the consummation or failure to
consummate the Merger on the market price of MRI Common Stock.

                               RECENT DEVELOPMENTS

    During fiscal 1996, MRI has consummated six acquisitions, four in the
diagnostic imaging business and two in the medical staffing business. MRI
consummated the acquisition of four diagnostic imaging centers located in New
York City in January 1996, three centers located in Florida in April 1996, one
center located in Florida in May 1996 and one center in New York in July 1996.
In addition, in January 1996, MRI consummated the acquisition of NurseCare Plus,
Inc., a California corporation based in San Diego, California, which provides
supplemental healthcare staffing services for clients, including hospitals,
clinics and home health agencies in Southern California, and in June 1996, MRI
consummated the acquisition of the assets of We Care-Allied Health Care
Services, a Florida general partnership, which provides supplemental healthcare
staffing services.

                                  ------------
                        JOINT PROXY STATEMENT/PROSPECTUS
                                  ------------

                                  INTRODUCTION

    This Joint Proxy Statement/Prospectus is being furnished to stockholders of
Medical Resources, Inc., a Delaware corporation ("MRI"), in connection with the
solicitation by the Board of Directors of MRI of proxies to be voted at a
Special Meeting of Stockholders of MRI (the "MRI Meeting"). This Joint Proxy
Statement/Prospectus is also being furnished to stockholders of NMR of America,
Inc., a Delaware corporation ("NMR"), in connection with the solicitation by the
Board of Directors of NMR of proxies to be voted at the Annual Meeting of
Stockholders of NMR (the "NMR Meeting").

    MRI, MRI Sub, Inc., a Delaware corporation which is a wholly-owned
subsidiary of MRI ("Subsidiary"), and NMR, have entered into an Agreement and
Plan of Merger dated May 20, 1996 (the "Merger Agreement"). A conformed copy of
the Merger Agreement (without the exhibits or schedules thereto) is attached to
this Joint Proxy Statement/Prospectus as Appendix A. Under the terms of the
Merger Agreement, NMR will become a wholly-owned subsidiary of MRI through the
merger of NMR into Subsidiary (the "Merger"), and each outstanding share of
Common Stock, par value $0.01 per share, of NMR ("NMR Common Stock") will
automatically convert into 0.6875 of a share of Common Stock, par value $0.01
per share, of MRI ("MRI Common Stock") and each outstanding warrant, option,
convertible debenture and other right exercisable for or convertible into shares
of NMR Common Stock ("NMR Derivative Securities") outstanding immediately prior
to the Merger will automatically be deemed exercisable or convertible, as the
case may be, into shares of MRI Common Stock at a ratio of 0.6875 of a share of
MRI Common Stock for each share of NMR Common Stock which otherwise would have
been issuable upon the exercise of such NMR Derivative Security had such NMR
Derivative Security been exercised or converted in full immediately prior to the
Merger (collectively, the "Exchange Ratio").

    The purpose of the MRI Meeting is to consider and vote upon proposals (i) to
approve the Merger Agreement and the issuance of shares of MRI Common Stock in
connection therewith (ITEM No. 1), and (ii) to approve an amendment to MRI's
Certificate of Incorporation which will increase the number of authorized shares
of MRI Common Stock from 20,000,000 to 50,000,000 (ITEM No. 2). Pursuant to the
terms of the Merger Agreement, MRI will be required to issue approximately
4,338,517 shares of MRI Common Stock (assuming none of the NMR Derivative
Securities are exercised or converted prior to the Merger). Approval of such
issuance by the stockholders of MRI is required by the rules of the National
Association of Securities Dealers, Inc., because shares of MRI Common Stock are
traded on the Nasdaq National Market and the number of shares proposed to be
issued in the Merger will exceed 20% of the pre-Merger issued and outstanding
shares of MRI Common Stock. THE VOTE WITH RESPECT TO ITEM NO. 2 -- RELATING TO
MRI ONLY -- WILL ONLY BE GIVEN EFFECT IF THE MERGER AGREEMENT IS APPROVED AND
THE MERGER IS CONSUMMATED.

    The purpose of the NMR Meeting is to consider and vote upon proposals (i) to
approve the Merger Agreement (ITEM No. 1), and, alternatively, (ii) to account
for the possibility that the Merger Agreement will not be approved by either the
stockholders of NMR or the stockholders of MRI, or that the Merger will not be
consummated for any other reason, to elect five (5) directors to the NMR Board
of Directors (ITEM No. 3). THE VOTE REGARDING ITEM NO. 3 -- RELATING TO NMR ONLY
- -- WILL ONLY BE GIVEN EFFECT IF THE MERGER AGREEMENT IS NOT APPROVED OR THE
MERGER IS NOT OTHERWISE CONSUMMATED.

    This Joint Proxy Statement/Prospectus is being mailed or given to
stockholders of MRI and NMR on or about August 1, 1996. The information set
forth in this Joint Proxy Statement/Prospectus concerning MRI and Subsidiary has
been furnished by MRI and the information concerning NMR has been furnished by
NMR.

    MRI has filed a registration statement on Form S-4 (the "Registration
Statement") with the Securities and Exchange Commission (the "SEC") registering
the shares of MRI Common Stock to be issued to stockholders of 


                                       22

RECORD DATE AND OUTSTANDING SHARES

  MRI

     Holders of record of MRI Common Stock at the close of business on July 29,

                             THE MERGER (ITEM NO.1)

BACKGROUND OF THE MERGER; NEGOTIATIONS; FAIRNESS OPINIONS

    For several years prior to the commencement of discussions between the
parties leading to the Merger Agreement, the respective managements of MRI and
NMR had been exploring various acquisition opportunities to expand MRI's and
NMR's respective networks of diagnostic imaging centers in order to complement
their existing multiple center provider networks or to enter new markets.
Management of MRI and NMR believed such expansion would enable their respective
companies to compete more effectively and efficiently in the current healthcare
environment by leveraging existing overhead and offering greater geographical
coverage to managed care and other entities which desired to use the respective
company's services for their members or enrollees. As part of this expansion
effort, from mid-1993 through early 1996, MRI acquired seven imaging centers in
Florida, four in New York and one in New Jersey, and NMR acquired four imaging
centers in Florida and three in Illinois.

    In addition, management of NMR and former and present management of MRI have
engaged in preliminary discussions with each other during the past several years
to explore possible business combinations from time to time. These preliminary
discussions terminated for various reasons, including the inability of the
companies to agree on financial valuations of each company, the structure of the
business combination and corporate governance issues pertaining to the combined
companies.

    On March 1, 1996, William D. Farrell, Co-President of MRI, and John P.
O'Malley III, Chief Financial Officer of NMR, met at NMR's offices in Murray
Hill, New Jersey, to generally explore the possibility of a business combination
between the two companies. At that time, there was no determination on the part
of either company to pursue a business combination; however, the respective
boards of directors of each company had previously authorized each company's
management to continue discussions.

    On April 26, 1996, Gary N. Siegler, Chairman of the Board of Directors of
MRI telephoned Joseph G. Dasti, Chairman of the Board of Directors, President
and Chief Executive Officer of NMR to further explore the possibility of a
business combination between the two companies. From April 29, 1996 through May
2, 1996, Messrs. Siegler, O'Malley and Dasti held a series of telephone
conversations which focused primarily on the structure of a possible transaction
and the ratio of shares of MRI Common Stock required to be issued to NMR
stockholders in the transaction.

    As a result of these discussions, MRI and NMR entered into a confidentiality
agreement as of May 1, 1996 pursuant to which each party agreed to keep
confidential certain proprietary information received from the other party and,
on May 2, 1996, MRI submitted to NMR an outline of the basic terms of the
Merger, including the Exchange Ratio of 0.6875 of a share of MRI Common Stock
for each outstanding share of NMR Common Stock.

     Commencing on May 6, 1996, representatives of MRI, including Mr. Siegler,
Mr. Farrell, Mr. Robert J. Adamson, Co-President of MRI, Mr. Neil H. Koffler, a
Director of MRI and a representative of 712 Advisory Services, Inc., a financial
advisor of MRI, and MRI's legal advisors held a series of telephone
conversations and meetings with Messrs. Dasti and O'Malley and NMR's legal
advisors to discuss the terms of the Merger proposal and to negotiate potential
documentation.

    As a result of each company's concern about the possibility of rumors
relating to the discussions between the two companies, the parties issued
separate press releases prior to the opening of the Nasdaq National Market on
May 7, 1996, which disclosed that preliminary discussions concerning a possible
business combination between the two companies had occurred. Both press releases
indicated that any transaction between the two parties would be subject to
several conditions, including the negotiation, execution and delivery of
definitive documentation.

    The Board of Directors of MRI met on May 7, 1996 to discuss the preliminary
terms of the Merger and authorized management to continue negotiations toward an
acceptable definitive agreement. In addition to its presentation at the May 7,
1996 Board of Directors meeting, MRI management regularly apprised the Board as
to the developments in their negotiations with NMR management.

    The Board of Directors of NMR met on May 8, 1996 to discuss the terms of
MRI's preliminary proposal. At the outset of this meeting, NMR's Chairman of the
Board, Joseph G. Dasti, recognized that his participation as a board member in
considering the Merger could create a potential conflict of interest since MRI's
merger proposal included, as a condition, termination of Mr. Dasti's existing
employment agreement with NMR in exchange for a lump sum cash 


                                       25


<PAGE>


payment and the engagement of Mr. Dasti as a consultant to MRI if the Merger
were consummated. Accordingly, NMR's Board of Directors, based on its
determination that it would be in the best interests of NMR and its stockholders
to designate a committee of NMR's directors who were not employed by NMR to
consider the Merger, appointed a special committee ("NMR Special Committee") of
directors consisting of Joseph Zappala, Dr. David L. Bloom, John A. Faraone and
Donald W. Arthur to review, analyze and direct negotiations of the terms of the
Merger, with the assistance of NMR's legal advisors, Chief Financial Officer and
staff.

    Following its appointment, the NMR Special Committee met at length on May 8
to discuss MRI's merger proposal and to review and analyze various financial and
other data relating to both companies. At the conclusion of its meeting, the NMR
Special Committee authorized management, with the advice of counsel, to proceed
with the negotiation of draft merger documentation, and determined to re-convene
for further deliberations. The NMR Special Committee also resolved, in
accordance with the terms of the proposed merger, to condition the transaction
on the Committee's prior receipt of the opinion of an independent financial
advisor that the Exchange Ratio was fair, from a financial point of view, to
NMR's stockholders.

    Over the following ten-day period, the NMR Special Committee met at length
on numerous occasions and regularly communicated, through Mr. Joseph Zappala who
acted as chairman of the Committee, with NMR's Chief Financial Officer and legal
counsel who continued to negotiate documentation and advise Mr. Zappala, on
behalf of the Committee, of the status of negotiations.

    On May 20, 1996, MRI and NMR announced that the Merger Agreement had been
approved and, on that day, had been executed by both parties. On May 24, 1996,
the MRI Board of Directors retained Dillon Read to advise the MRI Board of
Directors and MRI on the fairness to MRI, from a financial point of view, of the
Exchange Ratio. On May 29, 1996, the NMR Special Committee retained Cowen to
similarly advise the NMR Special Committee and NMR on the fairness, from a
financial point of view, to NMR's stockholders of the terms of the Merger
negotiated by NMR.

    Under the Merger Agreement, MRI and NMR were each granted a four-week period
to conduct a due diligence investigation of the other company during which
period either party could terminate the Merger Agreement without liability if
its due diligence findings were unsatisfactory. Accordingly, during the
four-week period following the May 20, 1996 approval and execution of the Merger
Agreement by MRI and NMR, each company engaged in its due diligence
investigation of the other company. Each company's due diligence investigation
was performed by its respective management with the assistance of accounting and
operations staff and legal advisors and, in the case of MRI, an industry
consultant, its accounting advisors and representatives of 712 Advisory
Services, Inc., MRI's financial advisor.

    At the same time that MRI and NMR conducted their due diligence
investigations, Cowen, the financial advisor to the NMR Special Committee, and
Dillon Read, the financial advisor to MRI's Board of Directors, also conducted
their due diligence and other analyses of each company. On June 13, 1996, Cowen
completed its work and delivered its written opinion to the NMR Special
Committee to the effect that, as of such date, the proposed Exchange Ratio was
fair from a financial point of view to the holders of the outstanding shares of
NMR Common Stock. On June 14, 1996, Dillon Read delivered its opinion
(subsequently confirmed in writing) to MRI's Board of Directors that the
Exchange Ratio was fair from a financial point of view to MRI.

    The Board of Directors of MRI and NMR had each determined to approve and
execute the Merger Agreement prior to receipt of a fairness opinion from their
respective financial advisors since MRI's Board and the NMR Special Committee
each believed that the preliminary analysis of the transaction and due diligence
conducted by each company's management supported their conclusion to execute the
Merger Agreement and proceed into the four-week due diligence period. In
addition, since the Merger Agreement permitted each company to terminate,
without liability, the Merger Agreement prior to June 19, 1996 based on an
unsatisfactory due diligence investigations, MRI's Board and the NMR Special
Committee each believed that their respective companies would be protected
against any negative findings during the due diligence period.

    MRI's Board and the NMR Special Committee sought fairness opinions as a
means of confirming their respective conclusions with respect to the fairness
from a financial point of view of the Exchange Ratio. In addition, the Merger
Agreement requires the receipt of fairness opinions as a condition to each
party's obligation to close the Merger, thereby giving each company the right to
terminate the Merger Agreement in the event its financial advisor determined
that the Exchange Ratio was not fair from a financial point of view to such
company.

<PAGE>


    On June 19, 1996, following conclusion of the due diligence review period,
the NMR Special Committee met to consider any outstanding issues resulting from
management's investigation of MRI. Management reported that it had
satisfactorily completed its review, with the assistance of counsel and its
accounting and operations staff, and advised that it had not discovered any
reason, from a due diligence perspective, to terminate the transaction. Based on
this report, the NMR Special Committee recommended to the full Board of NMR that
NMR proceed with the Merger. This recommendation was unanimously accepted by
NMR's Board of Directors.

    On June 13, 1996, June 18, 1996 and June 19, 1996, the MRI Board of
Directors held telephonic Board meetings in order to discuss and evaluate the
findings from MRI's due diligence review of NMR. Management and counsel reported
that they had satisfactorily completed their review of NMR and had not
discovered any reason, from a due diligence perspective, to terminate the
transaction. Based on this review, the MRI Board of Directors determined to
proceed with the Merger.

MRI'S REASONS FOR THE MERGER

    The Board of Directors of MRI has unanimously approved the Merger, and
believes that the Merger is in the best interests of MRI and its stockholders
due to the complementary nature of the businesses to be combined as a result of
the Merger. The Board of Directors of MRI views the Merger as a further step
towards fulfillment of one aspect of MRI's strategic development plan, which is
based upon leveraging MRI's existing overhead through expansion of MRI's network
of centers into states with entities possessing a multi-center presence in
desirable geographical markets. The Board of Directors of MRI views expansion of
MRI's operations into Maryland, Illinois and Pennsylvania to be a natural
extension of its current operations which may provide substantial opportunities
for additional growth through consolidation in the future. In addition, the
Board of Directors believes that NMR's current New Jersey and Florida operations
complement the presence of MRI's existing centers in those states. Also, MRI's
Board believes that the increased size and financial strength of MRI as a result
of the Merger will enhance its competitive abilities and enable it to take
greater advantage of acquisition opportunities in the diagnostic imaging
industry.

    In the course of its deliberations, MRI's Board of Directors reviewed and
considered the results of extensive due diligence, as well as information and
documentation relating to the Merger with MRI's management, which consulted with
its legal and accounting advisors. In connection with its review of the proposed
Merger, MRI's Board of Directors reviewed in detail the following factors which
it considered material in reaching its conclusion to approve the Merger:

       1. Information provided by NMR concerning the financial condition,
    results of operations and business of NMR, both on a historical and
    prospective basis, together with current industry, economic and market
    conditions applicable to NMR's business. The historical financial
    information provided by NMR included historical audited balance sheets,
    income statements and statements of cash flows for the year ended March 31,
    1995 and unaudited financial information for the year ended March 31, 1996.
    Such financial information indicated that most of NMR's diagnostic imaging
    centers had been profitable on a historical basis. MRI's management believes
    that by implementing its operating procedures and structure at the centers,
    it can continue to operate these centers profitably after the Merger.

       2. The complementary nature of the operations of MRI and NMR, which
    provided the Board of Directors of MRI with a substantial basis for its
    assessment that the potential synergies and efficiencies relating to the
    elimination of certain redundant administrative, professional and related
    expenditures could be achieved through the combination of the businesses.

       3. MRI believes that the Merger will enhance MRI's operating and
    financial base by substantially increasing MRI revenues. The Merger will
    increase MRI's capital base which should facilitate its ability to effect
    possible future debt and equity financings and acquisitions. MRI believes
    that its increased size and financial strength resulting from the Merger
    will permit it to provide more cost competitive services, thereby enabling
    it to compete more effectively for business. In addition, the increased
    revenues of the combined companies and geographically broader and larger
    network of centers will enable it to take greater advantage of acquisition
    opportunities in the diagnostic imaging services industry.

       4. The fact that it was a condition to the Merger that MRI receive a
    written opinion of Dillon Read with respect to the fairness to MRI, from a
    financial point of view, of the Exchange Ratio. See "The Merger--Background
    of the Merger; Negotiations; Fairness Opinion; Fairness Opinion of Dillon
    Read." 


                                       27


<PAGE>


     Receipt of such an opinion with a presentation of Dillon Read's
     methodologies and analyses would provide independent verification of the
     conclusion of MRI's Board that the Merger was in the best interests of 
     MRI's stockholders.

       5. Information available to the MRI Board of Directors relating to the
    risk factors of NMR. See "Risk Factors Regarding MRI and NMR." The MRI Board
    determined that the inherent risks of NMR's business were outweighed by the
    potential benefits of the transaction.

    After taking into consideration all of the factors set forth above, MRI's
Board determined that the Merger and the issuance of the MRI Common Stock in
connection therewith are in the best interests of the stockholders of MRI and
that MRI should proceed with the Merger at this time. In view of the wide
variety of factors considered in connection with its evaluation of the Merger,
MRI's Board did not find it practicable to, and did not, quantify or otherwise
attempt to assign relative weights to the specific factors considered in
reaching its decisions.

    THE AFFIRMATIVE VOTE OF A MAJORITY OF THE SHARES OF MRI COMMON STOCK PRESENT
IN PERSON OR REPRESENTED BY PROXY AND ENTITLED TO VOTE AT THE MRI MEETING WILL
BE REQUIRED TO APPROVE THE PROPOSAL TO APPROVE THE MERGER AGREEMENT. SEE "VOTING
AND PROXIES" ABOVE. THE BOARD OF DIRECTORS OF MRI RECOMMENDS A VOTE FOR APPROVAL
OF THE MERGER AGREEMENT.

FAIRNESS OPINION OF DILLON READ

    The Board of Directors of MRI retained Dillon Read to advise it as to the
fairness to MRI, from a financial point of view, of the consideration to be paid
by MRI in the Merger.

    On June 14, 1996, Dillon Read rendered its oral opinion, which was confirmed
by its written opinion dated June 14, 1996, to the MRI Board of Directors to the
effect that, based upon and subject to certain matters stated therein, as of the
date of such opinion, the consideration (referred to in the Merger Agreement and
herein as the "Exchange Ratio") to be paid by MRI in the Merger is fair to MRI
from a financial point of view.

    THE FULL TEXT OF DILLON READ'S OPINION DATED JUNE 14, 1996, WHICH SETS FORTH
A DESCRIPTION OF THE ASSUMPTIONS MADE, GENERAL PROCEDURES FOLLOWED, MATTERS
CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS
APPENDIX B. DILLON READ'S OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A
FINANCIAL POINT OF VIEW, OF THE CONSIDERATION TO BE PAID BY MRI IN THE MERGER
AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF MRI COMMON STOCK AS TO
HOW SUCH STOCKHOLDER SHOULD VOTE ON THE MERGER AGREEMENT. HOLDERS OF MRI COMMON
STOCK ARE URGED TO READ THE OPINION CAREFULLY IN ITS ENTIRETY, ESPECIALLY WITH
REGARD TO THE ASSUMPTIONS MADE AND MATTERS CONSIDERED BY DILLON READ. THE
SUMMARY OF THE OPINION SET FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.

    In arriving at its opinion, Dillon Read: (i) reviewed certain publicly
available business and historical financial information relating to MRI and NMR,
(ii) reviewed certain financial information and other data provided to Dillon
Read by MRI that is not publicly available relating to the business and
prospects of MRI, including financial projections prepared by the management of
MRI, (iii) reviewed certain financial information and other data provided to
Dillon Read by NMR that is not publicly available relating to the business and
prospects of NMR, including financial projections prepared by the management of
NMR, (iv) conducted discussions with members of the senior managements of MRI
and NMR, (v) reviewed publicly available financial and stock market data with
respect to certain other companies in lines of business Dillon Read believed to
be generally comparable to those of MRI and NMR, (vi) considered the pro forma
effects of the Merger on MRI's financial statements and reviewed certain
estimates of synergies prepared by the managements of MRI and NMR, (vii)
reviewed the historical market prices and trading volumes of MRI Common Stock
and NMR Common Stock, (viii) compared the financial terms of the Merger
Agreement with the financial terms of certain other transactions which Dillon
Read believed to be generally comparable to the Merger, (ix) reviewed the Merger
Agreement in the form provided to Dillon Read, and (x) conducted such other
financial studies, analyses and investigations, and considered such other
information, as Dillon Read deemed necessary or appropriate, but none of which
was, individually, material. Dillon Read's opinion was necessarily based on
economic, monetary and market conditions existing on the date thereof.

    In connection with its review, Dillon Read did not assume any responsibility
for independent verification of any of the foregoing information and, with MRI's
consent, relied on such information as being complete and accurate in 


                                       28


<PAGE>


all material respects. In addition, Dillon Read did not make any evaluation or
appraisal of any of the assets or liabilities (contingent or otherwise) of MRI
or NMR, nor was Dillon Read furnished with any such evaluation or appraisal.
With respect to the financial projections referred to above, Dillon Read
assumed, with MRI's consent, that they were reasonably prepared on bases
reflecting the best currently available estimates and judgments of MRI's and
NMR's management as to the future financial performance of each company. In
addition, although Dillon Read evaluated the consideration from a financial
point of view, Dillon Read was not asked to and did not recommend the specific
consideration to be paid in the Merger. No other limits were placed on Dillon
Read with respect to the investigations made or procedures followed by Dillon
Read in rendering its opinion.

    In arriving at its opinion, Dillon Read did not assign any particular weight
to any analysis or factor considered by it, but rather made qualitative
judgments based on its experience in rendering such opinions and on then
existing economic, monetary and market conditions as to the significance and
relevance of each analysis and factor. Accordingly, Dillon Read believes that
its analyses must be considered as a whole and that selecting portions of its
analyses and the factors considered, without considering all analyses and
factors, could create a misleading or incomplete view of the processes
underlying such analyses and its opinion. In its analyses, Dillon Read made
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond MRI's or NMR's
control. Any estimates contained in Dillon Read's analyses are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than as set forth therein. In addition,
analyses relating to the value of a business or securities do not purport to be
appraisals or to reflect the actual prices at which businesses or securities
might be sold.

    The following summarizes the material quantitative analyses performed by
Dillon Read in arriving at the opinion dated June 14, 1996 presented to the MRI
Board of Directors.

    Summary of Recent Acquisition Transactions. Using publicly available
information, Dillon Read reviewed the purchase prices and multiples paid in
selected mergers and acquisitions involving diagnostic imaging related companies
which Dillon Read deemed relevant in evaluating the Merger. Dillon Read reviewed
the acquisition of the diagnostic imaging business of MedAlliance, Inc. by
Health Images, Inc.; the acquisition of Medical Diagnostics, Inc. by Advanced
NMR Systems, Inc.; the acquisition of Radiation Care, Inc. by Oncology
Therapies, Inc.; and the acquisition of Morgan Medical Holdings, Inc. by NMR.
Multiples of equity value of the transaction to net income for the 12 months
preceding the acquisition announcement averaged 25.5x and ranged from 6.9x to
47.0x. Dillon Read noted that, based on the closing price of MRI Common Stock on
June 13, 1996 of $9.25 and an Exchange Ratio of 0.6875, the per share Merger
consideration of $6.36 per share of NMR Common Stock resulted in an equity value
to net income for the last 12 months multiple of 21.9x, below the average of the
transactions considered, but within the range. Dillon Read also considered the
multiples of the unlevered value of the transactions (consideration offered for
the equity plus the debt assumed less the cash of the acquired company) to the
operating cash flow and the operating profit of the acquired businesses for the
12 months preceding the acquisition announcement. The multiples of operating
cash flow averaged 9.1x and ranged from 3.8x to 19.6x. The multiples of
operating income averaged 11.4x and ranged from 8.0x to 15.1x. Based on the
closing price of MRI Common Stock on June 13, 1996, the Merger consideration
represented 8.5x operating cash flow, below the average of the transactions
considered, but within the range, and 14.1x operating profit, above the average
of the transactions considered, but within the range.

    Analysis of Selected Publicly Traded Comparable Companies in the Diagnostic
Imaging Business. Using publicly available information, Dillon Read reviewed the
stock prices and market multiples of common stocks of the following companies in
the diagnostic imaging business: Alliance Imaging, Inc.; Diagnostic Health
Services, Inc.; Health Images, Inc.; Healthcare Imaging Services, Inc.; Modern
Medical Modalities Corporation; Medical Imaging Centers of America, Inc.; SMT
Health Services, Inc.; and U.S. Diagnostic Labs, Inc. Dillon Read believes these
companies are engaged in lines of business that are generally comparable to
those of NMR. Dillon Read determined the equity market value and derived a "firm
value" (defined as equity market value adjusted by adding total debt and
subtracting cash and cash equivalents) for each of these comparable companies,
and calculated a range of such firm values as a multiple of the latest 12 months
sales, operating cash flow and operating profit. Firm value as a multiple of the
latest 12 months sales averaged 2.2x and ranged from 1.1x to 3.6x for these
comparable companies. Firm value as a multiple of the latest 12 months operating
cash flow averaged 7.5x and ranged from 3.2x to 13.5x. Firm value as a multiple
of the latest 12 months operating profit averaged 13.3x and ranged from 8.6x to
19.2x. Dillon Read noted that, based on the closing price of MRI Common Stock on
June 13, 1996, the Merger consideration was 2.8x sales,

8.5x operating cash flow and 14.1x operating profit, within the range for these
comparable companies for sales, operating cash flow and operating profit.

    No company, transaction or business used in the analyses described under
"-- Summary of Recent Acquisition Transactions" and "-- Analysis of Selected
Publicly Traded Comparable Companies in the Diagnostic Imaging Business" is
identical to MRI, NMR or the Merger. Accordingly, an analysis of the results
thereof necessarily involves complex considerations and judgments concerning
differences in financial and operating characteristics and other factors that
could affect the transaction or public trading or other values of the company or
companies to which they are being compared. Mathematical analysis (such as
determining the average or median) is not in itself a meaningful method of using
comparable acquisition or company data.

    Discounted Cash Flow Analysis for NMR. Dillon Read performed a discounted
cash flow analysis of NMR using a set of underlying operating projections which
were based upon the forecasts provided by NMR management. Utilizing this set of
projections for NMR, Dillon Read calculated the theoretical unlevered discounted
present value for NMR by adding together the present value of (i) the projected
stream of unlevered free cash flow through the year 2000 and (ii) the projected
value of NMR at the end of the year 2000 (the "Terminal Value"). The Terminal
Value was calculated based on multiples of earnings before interest, taxes,
depreciation and amortization for 2000 ranging from 6.0x to 8.0x. The unlevered
after-tax discount rates utilized in the discounted cash flow analyses ranged
from 12.0% to 14.0%.

    The theoretical value of NMR based on the set of projections produced a
range of value per share of NMR Common Stock of $5.86 to $8.04. Dillon Read
estimated the present value of cost savings and other synergies projected by MRI
management to be in the range of $1.94 to $2.74 per share of NMR Common Stock.
Dillon Read noted that, based on the closing price of MRI Common Stock on June
13, 1996, the Merger consideration was within the range of the theoretical value
based on the set of projections, and below the range when considering the
present value of the cost savings and other synergies projected by MRI
management.

    Contribution Analysis. Dillon Read analyzed the percentage of sales,
operating cash flow, operating income, net income and book value that each of
MRI and NMR would contribute to the total of the combined entity based on the
set of projections outlined immediately above. Based on this set of projections,
MRI's contribution to the combined entity ranged from 48% to 79%. Dillon Read
noted that, based on an Exchange Ratio of 0.6875 shares of MRI Common Stock for
each share of NMR Common Stock, the owners of MRI Common Stock would own
approximately 66% (after giving effect to (i) the conversion of in-the-money
convertible debt for MRI and NMR and (ii) the exercise of outstanding and
in-the-money options and warrants to purchase MRI Common Stock and NMR Common
Stock) of the combined entity, within the range of contribution of the set of
projections.

    Earnings per Share Impact. Dillon Read examined the impact of the Merger on
MRI earnings per share based on operating and financial projections for the two
companies. The projection of such earnings was based upon operating projections
provided by MRI management for MRI, assuming the Merger did not take place,
operating projections provided by NMR management for NMR, assuming the Merger
did not take place, and the cost savings and other synergies expected to result
from the Merger. This analysis indicated that the Merger would be dilutive to
MRI earnings per share in 1996 by $0.08, dilutive to MRI earnings per share in
1997 by $0.03, and accretive to MRI earnings per share in 1998 by $0.07.

    Historical Trading Analysis. Dillon Read reviewed the recent stock market
performance of MRI Common Stock and NMR Common Stock in relation to each other.
The analysis indicated that between June 13, 1995 and June 13, 1996 the ratio of
the price of a share of NMR Common Stock to the price of a share of MRI Common
Stock ranged between 0.41 and 1.37. Dillon Read also noted that such ratio was
0.58 based on the closing prices on June 13, 1995, 0.44 based on the closing
prices on May 3, 1996 (two trading days prior to the press release that MRI and
NMR were discussing a merger), 0.56 based on the average of the closing prices
for the 10 trading days ended June 13, 1996, 0.56 based on the average of the
closing prices for the 20 trading days ended June 13, 1996, 0.45 based on the
average of the closing prices for the 10 trading days ended May 3, 1996, and
0.47 based on the average of the closing prices for the 20 trading days ended
May 3, 1996.

Stock; however, in the ordinary course of its business, Dillon Read may trade
the securities of MRI and NMR for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.

    Pursuant to an engagement letter, dated May 24, 1996, between MRI and Dillon
Read, MRI agreed to pay Dillon Read a fee of $250,000 for services rendered in
connection with the preparation of its fairness opinion. MRI has also agreed to
reimburse Dillon Read for the expenses reasonably incurred by it in connection
with its engagement (including reasonable counsel fees) and to indemnify Dillon
Read and its officers, directors, employees, agents and controlling persons
against certain expenses, losses, claims, damages or liabilities in connection
with its services, including those arising under the federal securities laws.
Dillon Read's fee was not contingent on the conclusion reached in its opinion or
the consummation of the Merger.

NMR'S REASONS FOR THE MERGER

    The NMR Special Committee and full Board of Directors have unanimously
approved the Merger, and believe that the Merger is in the best interests of NMR
and its stockholders. NMR's Board believes that the increased size, capabilities
and financial strength of the combined entity resulting from the Merger will
enhance its ability to compete in a changing healthcare environment. NMR's Board
also believes that the combined company will benefit from an ability to offer to
various managed care organizations greater geographical coverage of its core
markets. Furthermore, the NMR Board believes that the combined company will be
better able, by virtue of its depth of experience and financial resources, to
achieve additional efficiencies through the continued consolidation of the
diagnostic imaging industry.

    Prior to reaching its conclusion, the NMR Special Committee and Board
reviewed and considered the results of a comprehensive due diligence process and
reviewed the terms of the Merger with NMR management and its legal and financial
advisors. During the course of its deliberations, the NMR Special Committee and
Board reviewed, in detail, the following factors which it considered to be
material in reaching its conclusion:

       1. Information provided by MRI concerning the financial condition,
    results of operations and business of MRI on a historical and prospective
    basis, together with current industry, economic and market conditions
    applicable to MRI's business. This information showed, to the satisfaction
    of the NMR Special Committee and Board of Directors, that MRI is a
    well-managed, geographically diversified company, and that NMR, based on the
    geographic locations of its centers, would benefit strategically from being
    part of MRI's existing center networks and planned expansion program. The
    NMR Special Committee and NMR Board of Directors determined that MRI was
    well managed based on a number of factors. First, MRI's results of
    operations on a historical basis indicated that the management of MRI had
    been successful in profitably expanding the company through acquisitions and
    internal growth, resulting in increasing revenues in each of the past
    several years. Second, MRI's results of operations for 1995 showed strong
    improvement in profitability as compared to the prior year. Thirdly, MRI's
    operating history reflected the fact that MRI's management has had extensive
    experience in managing a complex, geographically diversified network of
    medical diagnostic imaging centers and should have the management skills to
    successfully integrate the addition of NMR's network of centers.

       2. The compatibility of the management and operations of MRI and NMR. The
    NMR Special Committee and NMR Board of Directors determined that potential
    efficiencies and other advantages could be achieved through the Merger, and
    that the combined management of MRI and NMR would be able to guide the
    combined company to meet the objectives of the Merger. The NMR Special
    Committee and NMR Board of Directors believed that the following particular
    efficiencies and other advantages would be achieved through the Merger.
    First, the Merger would reduce administrative and overhead expenses by
    sharing the necessary administrative expenses with NMR and eliminating
    overlapping administrative functions. Second, the combined company would be
    better able to compete for business from large health care management
    companies because the combined company's operations would permit it to
    provide more cost competitive services. Further, the increased resources of
    the combined company would enhance its ability to improve revenues and
    profitability through further expansion of its network and through the
    negotiation of reductions in the combined company's operating costs. Lastly,
    large health care providers would be attracted to the combined company
    because such providers could negotiate imaging contracts covering a larger
    portion of the United States, thereby reducing their costs.


                                       31


<PAGE>


       3. The requirement that consummation of the Merger be conditioned upon
    the written opinion of Cowen with respect to the fairness to the holders of
    NMR Common Stock, from a financial point of view, of the proposed Exchange
    Ratio to be paid to the stockholders of NMR pursuant to the Merger
    Agreement, which would provide independent verification of the conclusion of
    NMR's Board and Special Committee that the Merger is in the best interests
    of NMR stockholders. See "The Merger--Background of the Merger;
    Negotiations; Fairness Opinions; Fairness Opinion of Cowen."

       4. Alternative growth strategy through acquisition of individual
    diagnostic imaging centers. The Merger was deemed by NMR's Board to be a
    more favorable means of growing the company than the alternative growth
    strategy of acquiring additional individual diagnostic imaging centers.

       5. Information available to NMR's Board relating to the risk factors of
    MRI. See "Risk Factors Regarding MRI and NMR." The NMR Board determined that
    the inherent risks of MRI's business were outweighed by the potential
    benefits of the transaction.

    After taking into consideration all of the factors set forth above, the NMR
Special Committee and Board determined that the Merger was in the best interests
of the stockholders of NMR. In view of the various factors considered in
connection with its evaluation of the Merger, the NMR Special Committee and NMR
Board did not find it practicable to, and did not, quantify or otherwise attempt
to assign relative weights to the specific factors considered in reaching its
decision.

     THE AFFIRMATIVE VOTE OF A MAJORITY OF THE OUTSTANDING SHARES OF NMR COMMON
STOCK WILL BE NECESSARY TO APPROVE THE MERGER AGREEMENT. SEE "VOTING AND
PROXIES" ABOVE. THE BOARD OF DIRECTORS OF NMR RECOMMENDS A VOTE FOR APPROVAL OF
THE MERGER AGREEMENT.

     IN APPROVING THE MERGER AGREEMENT, A MEMBER OF THE BOARD OF DIRECTORS OF
NMR MAY BE DEEMED TO HAVE CERTAIN CONFLICTS OF INTEREST. SEE "THE MERGER --
BACKGROUND OF THE MERGER; NEGOTIATIONS; FAIRNESS OPINIONS" AND "TERMS OF THE
MERGER -- INTEREST OF CERTAIN PERSONS IN THE MERGER."

FAIRNESS OPINION OF COWEN

    Cowen has acted as financial advisor to the NMR Special Committee in
connection with the Merger. As part of this assignment, Cowen was asked to
render an opinion to the NMR Special Committee as to the fairness,from a
financial point of view, to the holders of the outstanding shares of NMR Common
Stock of the proposed Exchange Ratio.

    On June 13, 1996, Cowen delivered its oral opinion confirmed in writing as
of the same date to the NMR Special Committee to the effect that, as of that
date, the proposed Exchange Ratio was fair, from a financial point of view, to
the holders of the outstanding shares of NMR Common Stock. THE FULL TEXT OF THE
WRITTEN OPINION OF COWEN, DATED JUNE 13, 1996, WHICH SETS FORTH THE ASSUMPTIONS
MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED, LIMITATIONS ON AND THE SCOPE OF
THE REVIEW BY COWEN IN RENDERING ITS OPINION IS ATTACHED AS APPENDIX C TO THIS
JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE
SUMMARY OF COWEN'S WRITTEN OPINION SET FORTH IN THE JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCES TO THE FULL TEXT
OF SUCH OPINION. NMR STOCKHOLDERS ARE URGED TO READ COWEN'S OPINION IN ITS
ENTIRETY. Cowen's analyses and opinion were prepared for the NMR Special
Committee and are directed only to the fairness, from a financial point of view,
to the holders of the outstanding shares of NMR Common Stock of the proposed
Exchange Ratio and do not constitute an opinion as to the merits of the Merger
or a recommendation to any holder of NMR Common Stock as to how to vote at the
NMR Meeting.

    Cowen was selected by the NMR Special Committee as its financial advisor,
and to render an opinion to the NMR Special Committee, because Cowen is a
nationally recognized investment banking firm and its principals have
substantial experience in transactions similar to the Merger and are familiar
with NMR and its business. In the ordinary course of its investment banking
services, Cowen is regularly engaged in the valuation and pricing of businesses
and their securities in connection with mergers and acquisitions and valuations
for corporate and other purposes and in advising corporate securities issuers on
related matters. In addition, in the ordinary course of its business, Cowen may
trade the debt and equity securities of NMR and MRI for its own account or the
accounts of its customers, and, accordingly, it may at any time hold a long or
short position in such securities.

    In connection with its opinion, Cowen, among other things: (1) reviewed
NMR's financial statements for the three fiscal years ended March 31, 1996,
certain publicly available filings with the SEC and certain other relevant
financial and operating data of NMR; (2) reviewed MRI's financial statements for
the three fiscal years ended December 31, 1995 and the quarter ended March 31,
1996, certain publicly available filings with the SEC and certain other relevant
financial and operating data of MRI; (3) reviewed the Merger Agreement; (4) held
meetings and discussions with management and senior personnel of NMR and MRI to
discuss the business, operations, historical financial results and future
prospects of NMR and MRI; (5) reviewed financial projections furnished to Cowen
by the management of NMR and MRI, including among other things, the capital
structure, sales, net income, cash flow, capital requirements and other data of
NMR and MRI which Cowen deemed relevant; (6) reviewed the valuation of NMR and
MRI in comparison to other similar publicly traded companies; (7) reviewed the
historical prices and trading activity of the securities of NMR and MRI and
compared those trading histories with those of other companies which Cowen
deemed relevant; (8) analyzed the potential pro forma financial effects of the
Merger contemplated by the Merger Agreement; (9) reviewed the proposed financial
terms of the Merger and compared them with the financial terms of certain other
business combinations Cowen deemed relevant; and (10) conducted such other
studies, analysis, inquiries and investigations Cowen deemed appropriate. Cowen
was not requested to, and did not, solicit third party indications of interest
in acquiring NMR.

    In rendering its opinion, Cowen assumed and relied, without independent
verification, upon the accuracy and completeness of the financial and other
information that was available to Cowen from public sources, that was provided
to Cowen by NMR or MRI or their representatives, or that was otherwise reviewed
by Cowen. In addition, with respect to the financial projections furnished to
Cowen by the management of NMR and MRI, Cowen assumed the attainability of the
financial results therein and that they were reasonably prepared judgments of
the future financial performance of NMR and MRI. Because such projections are
inherently subject to uncertainty, Cowen assumes no responsibility for their
accuracy. Cowen did not make any independent evaluation or appraisal of the
assets or liabilities of NMR or MRI, nor has Cowen been furnished with any such
appraisals. Cowen made no independent investigation of any legal matters
affecting NMR or MRI. Cowen's opinion was necessarily based on economic, market
and other conditions as in effect on, and the information made available to
Cowen as of, June 13, 1996. Although developments subsequent to June 13, 1996
may affect Cowen's opinion, Cowen does not have any obligation to update, revise
or reaffirm its opinion.

    The following paragraphs summarize the significant quantitative and
qualitative analyses performed by Cowen in arriving at its opinion. Cowen
performed certain procedures, including each of the financial analyses described
below, and reviewed with the management of NMR and MRI the assumptions on which
such analyses were based and other factors, including the current and projected
financial results of NMR and MRI. No limitations were imposed by the NMR Special
Committee with respect to the investigations made or procedures followed by
Cowen in rendering its opinion.

  Analysis Relating to NMR

    Comparative Company Analysis. Cowen compared the historical, current and
relevant projected financial and operating results of NMR with that of selected
publicly traded imaging companies it deemed relevant (the "Comparative Imaging
Company Index"). The companies in the Comparative Imaging Company Index were
chosen based upon conversations with NMR management as to companies which
possess general business, operating and financial characteristics representative
of companies in the industry in which NMR and MRI operate. The Comparative
Imaging Company Index consisted of Alliance Imaging, Inc., Diagnostic Health
Services, Inc., Health Images, Inc., Heico Corp., Medical Imaging Centers of
America, Inc., SMT Health Services, Inc. and U.S. Diagnostic Labs, Inc.

    In order to assess the relative public market valuations of NMR and the
Comparative Imaging Company Index, Cowen performed a market analysis of NMR and
the Comparative Imaging Company Index. With respect to such analysis, Cowen
calculated a range of market multiples for each of the companies in the
Comparative Imaging Company Index based on : (i) the market capitalization
(total number of common shares outstanding multiplied by the closing market
price per share on June 7, 1996 plus the last reported total debt, capitalized
leases, preferred stock and other relevant adjustments minus cash, cash
equivalents and other relevant adjustments (the "Market Capitalization")) of
each of the companies in the Comparative Imaging Company Index divided by such
company's latest four quarters net revenue, earnings before interest, taxes,
depreciation and amortization ("EBITDA"), and 


                                       33


<PAGE>


earnings before interest and taxes ("EBIT"); (ii) the market price (the closing
market price per share on June 7, 1996 (the "Market Price")) of each of the
companies in the Comparative Imaging Company Index divided by such company's
estimated calendar 1996 and calendar 1997 earnings per share ("EPS") (as
estimated by the Institutional Brokers Estimate Service("IBES") and/or certain
research reports); and (iii) the market value (total common shares outstanding
multiplied by the Market Price (the "Market Value")) of each of the companies in
the Comparative Imaging Company Index divided by such company's latest net
income and book value. The range of market multiples for the Comparative Imaging
Company Index included: (i) Market Capitalization to latest four quarters net
revenue multiples of 1.11x to 3.72x; (ii) Market Capitalization to latest four
quarters EBITDA multiples of 3.4x to 12.7x; (iii) Market Capitalization to
latest four quarters EBIT multiples of 6.2x to 21.7x; (iv) Market Value to
latest four quarters net income multiples of 14.7x to 28.2x; (v) Market Value to
latest four quarters book value multiples of 1.3x to 7.1x; (vi) Market Price to
estimated calendar 1996 EPS multiples of 13.4x to 23.3x; and (vii) Market Price
to estimated calendar 1997 EPS multiples of 11.5x to 18.3x. Based on the above
measures, Cowen then compared NMR's market multiples, based on NMR's
pre-announcement Market Price on May 6, 1996, with the Comparative Imaging
Company Index median market multiples in order to establish the relationship
between NMR's market multiples and those of the Comparative Imaging Company
Index. With respect to such review, Cowen noted that: (i) NMR's Market
Capitalization to latest four quarters net revenue multiple was 1.90x compared
with a median Market Capitalization to latest four quarters net revenue multiple
of 1.66x for the Comparative Imaging Company Index; (ii) NMR's Market
Capitalization to latest four quarters EBITDA multiple was 6.0x compared with a
median Market Capitalization to latest four quarters EBITDA multiple of 5.9x for
the Comparative Imaging Company Index; (iii) NMR's Market Capitalization to
latest four quarters EBIT multiple was 10.1x compared with a median Market
Capitalization to latest four quarters EBIT multiple of 13.7x for the
Comparative Imaging Company Index; (iv) NMR's Market Value to latest four
quarters net income multiple was 16.2x compared with a median Market Value to
latest four quarters net income multiple of 16.4x for the Comparative Imaging
Company Index; (v) NMR's Market Value to latest four quarters book value
multiple was 1.3x compared with a median Market Value to latest four quarters
book value multiple of 4.1x for the Comparative Imaging Company Index; (vi)
NMR's Market Price to estimated fiscal 1997 EPS multiple was 12.1x compared with
a median Market Price to estimated calendar 1996 EPS multiple of 15.8x for the
Comparative Imaging Company Index; and (vii) NMR's Market Price to estimated
fiscal 1998 EPS multiple was 9.8x compared with a median Market Price to
estimated calendar 1997 EPS multiple of 12.4x for the Comparative Imaging
Company Index.

    Using such information, Cowen derived a range of implied enterprise values
(a theoretical aggregate valuation of a corporate entity before adjustments for
non-operating assets and liabilities ("Implied Enterprise Value")) for NMR of
$28.8 million to $61.5 million by applying the aforementioned market multiples
of the Comparative Imaging Company Index to the appropriate financial statistics
of NMR. The range of Implied Enterprise Values of NMR was then adjusted for
non-operating assets and liabilities, where relevant, to yield implied equity
values of NMR of $28.8 million to $51.1 million. The range of implied equity
values of NMR was then divided by the fully diluted shares of NMR Common Stock
outstanding to yield implied values of $3.55 to $6.30 per fully diluted share.

    Discounted Cash Flow Analysis. Cowen performed a discounted cash flow
analysis of NMR based on the fiscal 1997 to fiscal 2001 financial forecast for
NMR provided by NMR management (the "NMR Financial Forecast"). Using information
set forth in the NMR Financial Forecast, Cowen calculated the estimated "free
cash flow" based on projected unleveraged net income (earnings before interest
and after taxes ("EBIAT")) adjusted for: (i) certain non-cash items (i.e.,
depreciation and amortization); (ii) projected capital expenditures; and (iii)
projected non-cash working capital investment.

    Cowen analyzed the NMR Financial Forecast and discounted the stream of cash
flows provided in such projections back to July 31, 1996 using discount rates of
14.0% to 16.0%. To estimate the residual value of NMR at the end of the NMR
Financial Forecast Period, Cowen applied terminal multiples of 4.9x to 6.9x to
the projected fiscal 2001 EBITDA and discounted such value estimates back to
July 31, 1996 using discount rates of 14.0% to 16.0%. Cowen then summed the
present values of the free cash flows and the present values of the residual
values to derive a range of Implied Enterprise Values for NMR of $49.4 million
to $65.5 million. The range of Implied Enterprise Values of NMR was then
adjusted for non-operating assets and liabilities, where relevant, to yield
implied equity values of NMR of $39.1 million to $55.5 million. The range of
implied equity values of NMR was then divided by the fully diluted shares of NMR
Common Stock outstanding to yield implied values of $4.82 to $6.80 per
fully diluted share.

<PAGE>


    Comparative Transaction Analysis. Cowen compared certain financial and
operating statistics of NMR with that of such financial and operating results of
selected relevant imaging companies (the "Acquired Comparative Imaging
Companies") immediately prior to being acquired. The transactions involving the
Acquired Comparative Imaging Companies were chosen based upon conversations with
NMR management as to acquired companies which possessed general business,
operating and financial characteristics representative of companies in the
industry in which NMR operates. The selected acquisition transactions involving
the Acquired Comparative Imaging Companies, which occurred or were announced
between April 15, 1995 and September 15, 1995, included (acquirer/acquired
company): Health Images/MedAlliance; Advanced NMR Systems, Inc./Medical
Diagnostics, Inc.; and NMR/Morgan Medical Holdings, Inc.

    Cowen performed an analysis of the multiples paid in the selected
acquisition transactions involving the Acquired Comparative Imaging Companies in
which it analyzed the adjusted purchase price (the Equity Cost, as defined
below, plus latest reported total debt and capitalized leases, minus cash, cash
equivalents and cash proceeds from the assumed exercise of in-the-money options
(the "Adjusted Purchase Price")) for each of the Acquired Comparative Imaging
Companies and divided such amount by each of such company's respective latest
four quarters net revenues, EBITDA and EBIT immediately prior to being acquired
to give a range of purchase price multiples. Cowen also analyzed the equity cost
(offer price per share multiplied by total common shares outstanding (the
"Equity Cost")) for each of the Acquired Comparative Imaging Companies acquired
in the selected transactions and divided such amount by each of such company's
respective latest four quarters net income and book value immediately prior to
being acquired to give a range of purchase price multiples. Additionally, Cowen
analyzed the premium paid over the pre-announcement stock price (the percent
increase of the offer price per share over the pre-announcement closing market
price (the "Premium over Stock Price")) for each of the Acquired Comparative
Imaging Companies acquired in the selected transactions. The range of purchase
price multiples and Premium over Stock Price paid in the selected acquisition
transactions involving the Acquired Comparative Imaging Companies included: (i)
Adjusted Purchase Price to latest four quarters (pre-acquisition) net revenue
multiples of 1.43x to 1.93x; (ii) Adjusted Purchase Price to latest four
quarters (pre-acquisition) EBITDA multiples of 4.4x to 7.0x; (iii) Adjusted
Purchase Price to latest four quarters (pre-acquisition) EBIT multiples of 10.7x
to 14.1x; (iv) Equity Cost to latest four quarters (pre-acquisition) net income
multiples of 10.8x to 50.9x; (v) Equity Cost to latest four quarters
(pre-acquisition) book value multiples of 1.2x to 3.5x; and (vi) Premium over
Stock Price of 50.0% to 62.0%.

    Using such information, Cowen also compared the implied purchase price
multiples and Premium over Stock Price of the Exchange Ratio to the median
purchase price multiples and Premium over Stock Price paid in the aforementioned
acquisition transactions. Such analysis illustrated that: (i) the implied
Adjusted Purchase Price to the latest four quarters net revenue multiple of the
Exchange Ratio was 2.70x compared with a median latest four quarters net revenue
multiple of 1.62x in the selected transactions; (ii) the implied Adjusted
Purchase Price to the latest four quarters EBITDA multiple of the Exchange Ratio
was 8.5x compared with a median latest four quarters EBITDA multiple of 5.8x in
the selected transactions; (iii) the implied Adjusted Purchase Price to the
latest four quarters EBIT multiple of the Exchange Ratio was 14.3x compared with
a median latest four quarters EBIT multiple of 11.7x in the selected
transactions; (iv) the implied Equity Cost to the latest four quarters net
income multiple of the Exchange Ratio was 28.1x compared with a median latest
four quarters net income multiple of 24.0x in the selected transactions; (v) the
implied Equity Cost to the latest four quarters book value multiple of the
Exchange Ratio was 2.1x compared with a median latest four quarters book value
multiple of 2.6x in the selected transactions; and (vi) the Premium over Stock
Price of the Exchange Ratio was 103.6% compared with a median Premium over Stock
Price of 56.0% in the selected transactions.

    Using such information, Cowen derived a range of Implied Enterprise Values
for NMR of $38.4 million to $59.9 million by applying the aforementioned market
multiples of the Comparative Imaging Company Index to the appropriate financial
statistics of NMR. The range of Implied Enterprise Values of NMR was then
adjusted for non-operating assets and liabilities, where relevant, to yield
implied equity values of NMR of $28.1 million to $59.9 million. The range of
implied equity values of NMR was then divided by the fully diluted shares of NMR
Common Stock outstanding to yield implied values of $3.46 to $7.39 per fully
diluted share.

    Other Factors. In rendering its opinion, Cowen considered certain other
factors with the respect to NMR, including: (i) a review of NMR's business and
operations and the industry in which NMR operates to increase its understanding
of NMR's business and its position in the industry within which NMR operates;
(ii) a review of NMR's historical operating results and the NMR Financial
Forecast to increase its understanding of the financial 


                                       35


<PAGE>


performance and prospects of NMR's business; (iii) a review of the current book
value of NMR; and (iv) a review of the stock price performance of NMR, the
Comparative Imaging Company Index and selected market indices to provide
perspective on current and historical public market valuations and stock price
performance of NMR relative to selected market indices.

  Analysis Relating to MRI

    Comparative Company Analysis. Cowen compared the historical, current and
relevant projected financial and operating results of MRI with that of such
financial and operating results of selected publicly traded imaging companies in
the Comparative Imaging Company Index. The companies in the Comparative Imaging
Company Index were chosen based upon conversations with NMR management as to
companies which possess general business, operating and financial
characteristics representative of companies in the industry in which NMR and MRI
operate. In addition, Cowen compared the historical, current and relevant
projected financial and operating results of MRI with that of such financial and
operating results of selected staffing companies it deemed relevant which
included Barrett Business Services, Inc., Career Horizons, Inc., Interim
Services, Inc., Kelly Services Inc., Manpower Inc., Norrell Corp., Personnel
Group of America, Inc. and Robert Half International, Inc. (the "Comparative
Staffing Company Index"). However, Cowen accorded less weight to the analysis
relating to the Comparative Staffing Company Index than to the Comparative
Imaging Company Index, primarily due to the lack of historical earnings
contributed to MRI by its staffing business.

    In order to assess the relative public market valuations of MRI and the
Comparative Imaging Company Index, Cowen performed a market analysis of MRI and
the Comparative Imaging Company Index. With respect to such analysis, Cowen
calculated a range of market multiples for each of the companies in the
Comparative Imaging Company Index based on: (i) the Market Capitalization of
each of the companies in the Comparative Imaging Company Index divided by such
company's latest four quarters net revenue, EBITDA and EBIT; (ii) the Market
Price of each of the companies in the Comparative Imaging Company Index divided
by such company's estimated calendar 1996 and calendar 1997 EPS (as per IBES
and/or certain research reports); and (iii) the Market Value of each of the
companies in the Comparative Imaging Company Index divided by such latest
company's net income and book value. The range of market multiples for the
Comparative Imaging Company Index included: (i) Market Capitalization to latest
four quarters net revenue multiples of 1.11x to 3.72x; (ii) Market
Capitalization to latest four quarters EBITDA multiples of 3.4x to 12.7x; (iii)
Market Capitalization to latest four quarters EBIT multiples of 6.2x to 21.7x;
(iv) Market Value to latest four quarters net income multiples of 14.7x to
28.2x; (v) Market Value to latest four quarters book value multiples of 1.3x to
7.1x; (vi) Market Price to estimated calendar 1996 EPS multiples of 13.4x to
23.3x; and (vii) Market Price to estimated calendar 1997 EPS multiples of 11.5x
to 18.3x. Based on the above measures, Cowen then compared MRI's market
multiples, based on its Market Price, with the Comparative Imaging Company Index
median market multiples in order to establish the relationship between MRI's
market multiples and those of the Comparative Imaging Company Index. With
respect to such review, Cowen noted that: (i) MRI's Market Capitalization to
latest four quarters net revenue multiple was 1.81x compared with a median
Market Capitalization to latest four quarters net revenue multiple of 1.66x for
the Comparative Imaging Company Index; (ii) MRI's Market Capitalization to
latest four quarters EBITDA multiple was 8.0x compared with a median Market
Capitalization to latest four quarters EBITDA multiple of 5.9x for the
Comparative Imaging Company Index; (iii) MRI's Market Capitalization to latest
four quarters EBIT multiple was 12.8x compared with a median Market
Capitalization to latest four quarters EBIT multiple of 13.7x for the
Comparative Imaging Company Index; (iv) MRI's Market Value to latest four
quarters net income multiple was 18.2x compared with a median Market Value to
latest four quarters net income multiple of 16.4x for the Comparative Imaging
Company Index; (v) MRI's Market Value to latest four quarters book value
multiple was 4.3x compared with a median Market Value to latest four quarters
book value multiple of 4.1x for the Comparative Imaging Company Index; (vi)
MRI's Market Price to estimated calendar 1996 EPS multiple was 14.7x compared
with a median Market Price to estimated calendar 1996 EPS multiple of 15.8x for
the Comparative Imaging Company Index; and (vii) MRI's Market Price to estimated
calendar 1997 EPS multiple was 11.9x compared with a median Market Price to
estimated calendar 1997 EPS multiple of 12.4x for the Comparative Imaging 
Company Index.

    In addition, Cowen performed a market analysis of MRI and the Comparative
Staffing Company Index. With respect to such analysis, Cowen calculated a range
of market multiples for each of the companies in the Comparative Staffing
Company Index based on: (i) the Market Capitalization of each of the companies
in the Comparative Staffing Company Index divided by such company's latest four
quarters net revenue, EBITDA and EBIT; (ii) the Market Price 


                                       36


<PAGE>


of each of the companies in the Comparative Staffing Company Index divided by
such company's estimated calendar 1996 and calendar 1997 EPS (as per IBES and/or
certain research reports); and (iii) the Market Value of each of the companies
in the Comparative Staffing Company Index divided by such latest company's net
income and book value. The range of market multiples for the Comparative
Staffing Company Index included: (i) Market Capitalization to latest four
quarters net revenue multiples of 0.35x to 2.30x; (ii) Market Capitalization to
latest four quarters EBITDA multiples of 7.4x to 27.6x; (iii) Market
Capitalization to latest four quarters EBIT multiples of 9.1x to 32.2x; (iv)
Market Value to latest four quarters net income multiples of 15.8x to 47.1x; (v)
Market Value to latest four quarters book value multiples of 2.3x to 7.6x; (vi)
Market Price to estimated calendar 1996 EPS multiples of 14.5x to 35.5x; and
(vii) Market Price to estimated calendar 1997 EPS multiples of 13.1x to 28.1x.
Based on the above measures, Cowen then compared MRI's market multiples, based
on its Market Price, with the Comparative Staffing Company Index median market
multiples in order to establish the relationship between MRI's market multiples
and those of the Comparative Staffing Company Index. With respect to such
review, Cowen noted that: (i) MRI's Market Capitalization to latest four
quarters net revenue multiple was 1.81x compared with a median Market
Capitalization to latest four quarters net revenue multiple of 0.70x for the
Comparative Staffing Company Index; (ii) MRI's Market Capitalization to latest
four quarters EBITDA multiple was 8.0x compared with a median Market
Capitalization to latest four quarters EBITDA multiple of 14.0x for the
Comparative Staffing Company Index; (iii) MRI's Market Capitalization to latest
four quarters EBIT multiple was 12.8x compared with a median Market
Capitalization to latest four quarters EBIT multiple of 17.2x for the
Comparative Staffing Company Index; (iv) MRI's Market Value to latest four
quarters net income multiple was 18.2x compared with a median Market Value to
latest four quarters net income multiple of 28.3x for the Comparative Staffing
Company Index; (v) MRI's Market Value to latest four quarters book value
multiple was 4.3x compared with a median Market Value to latest four quarters
book value multiple of 4.8x for the Comparative Staffing Company Index; (vi)
MRI's Market Price to estimated calendar 1996 EPS multiple was 14.7x compared
with a median Market Price to estimated calendar 1996 EPS multiple of 24.3x for
the Comparative Staffing Company Index; and (vii) MRI's Market Price to
estimated calendar 1997 EPS multiple was 11.9x compared with a median Market
Price to estimated calendar 1997 EPS multiple of 19.7x for the Comparative
StaffingCompany Index.

    Pro Forma Analysis. Cowen's analysis of the potential pro forma financial
effects of the Merger on MRI was based principally upon the fiscal 1996 to 1998
financial forecast for MRI provided by MRI management (the "MRI Forecast") and
the NMR Financial Forecast for fiscal 1997 to fiscal 1999. Cowen's pro forma
financial forecast assumed, among other things, that the Merger: (i) would
provide 0.6875 of a share of MRI Common Stock in exchange for each share of NMR
Common Stock; (ii) will be accounted for under the purchase method of
accounting; (iii) will be treated as a tax free exchange; and (iv) will result
in the realization of certain strategic and operating benefits. Among other
things, Cowen's pro forma analysis is dependent upon the ability of both NMR and
MRI to realize the projected operating performance assumptions of the NMR
Financial Forecast and the MRI Financial Forecast, respectively.

    Using the data and other information referred to above, Cowen's pro forma
financial analysis suggested that the Merger should result in dilution to MRI's
EPS in each of the fiscal years 1996 to 1998 with such dilution declining in
each year over the same period. Cowen's pro forma analysis also suggested that
MRI's total debt as a percent of total capitalization should decrease as a
result of the Merger.

    Other Factors. In rendering its opinion, Cowen considered certain other
factors with respect to MRI, including: (i) a review of MRI's business and
operations and the industry in which MRI operates to increase its understanding
of MRI's business and its position in the industry within which MRI operates;
(ii) a review of MRI's historical operating results and the MRI Financial
Forecast to increase its understanding of the financial performance and
prospects of MRI's business; (iii) a review of the current book value of MRI;
and (iv) a review of the stock price performance of MRI, the Comparative Imaging
Company Index, the Comparative Staffing Company Index and selected market
indices to provide perspective on current and historical public market
valuations and stock price performance of MRI relative to selected market
indices.

    The summary set forth above does not purport to be a complete description of
the analyses performed by Cowen. The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant quantitative
methods of financial analyses and the application of those methods to the
particular circumstances and, therefore, such an opinion is not readily
susceptible to partial analysis or summary description. Accordingly,
notwithstanding the factors summarized above, Cowen believes that its analysis
must be considered as a whole and 


                                       37


<PAGE>


that considering any portion of such analysis and of the factors considered,
without considering all analyses and factors, could create a misleading or
incomplete view of the process underlying its opinion. In its analyses, Cowen
made numerous assumptions with respect to industry performance, general business
and economic conditions and other matters, many of which are beyond control of
NMR and MRI. Any estimates contained in these analyses are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than as set forth therein, and neither
NMR, MRI nor Cowen assumes responsibility for their accuracy. In addition,
analyses relating to the value of businesses do not purport to be appraisals or
to reflect the prices at which businesses may actually be sold.

    As compensation for its services as financial advisor to the NMR Special
Committee, NMR has paid Cowen a fee of $200,000. NMR has also agreed to
reimburse Cowen for its out-of-pocket expenses in an amount not to exceed
$15,000 without the prior written consent of NMR and to indemnify Cowen against
certain liabilities, including liabilities under the federal securities laws,
relating to, arising out of or in connection with Cowen's services as financial
advisor to the NMR Special Committee, unless such liabilities arose out of
Cowen's gross negligence or willful misconduct. Payment of Cowen's fee was not
contingent upon the conclusion reached in its opinion or the consummation of the
Merger.

                               TERMS OF THE MERGER

    The following is a discussion of the material terms of the Merger Agreement.
This section of the Joint Proxy Statement/Prospectus does not contain a complete
explanation or description of the Merger Agreement and is qualified in its
entirety by reference to the terms of the Merger Agreement, a conformed copy of
which (without the exhibits or schedules thereto) is attached to this Joint
Proxy Statement/Prospectus as Appendix A and incorporated herein by reference.

GENERAL

    The Merger Agreement provides that, upon effectiveness of the Merger, NMR
will be merged with and into Subsidiary, the separate existence of NMR will
cease, and Subsidiary, the surviving corporation, will be a wholly-owned
subsidiary of MRI. As a consequence of the Merger, title to all of the property
and assets of Subsidiary and NMR will be vested or continue to be vested in
Subsidiary, and Subsidiary will be subject to all of the liabilities of
Subsidiary and NMR. Subsidiary has been formed solely for the purpose of
effecting the Merger, and has conducted no business and has no material assets
or obligations other than as contemplated by the Merger Agreement.

    The Merger Agreement further provides that upon consummation of the Merger,
holders of shares of NMR Common Stock will receive shares of MRI Common Stock at
an Exchange Ratio of 0.6875 of a share of MRI Common Stock for each issued and
outstanding share of NMR Common Stock. See "The Merger -- Background of the
Merger; Negotiations; Fairness Opinions."

    As of the date hereof, the amount of shares of MRI Common Stock issuable in
connection with the Merger would constitute approximately 48.9% of the amount of
issued and outstanding shares of MRI Common Stock prior to the Merger, without
giving effect to the exercise or conversion of any of MRI's or NMR's warrants,
options or convertible securities outstanding as of the date hereof.

    The Merger Agreement provides that, as soon as practicable following
satisfaction of all conditions to the Merger, including the approval of the
Merger Agreement by the stockholders of MRI and by the stockholders of NMR, a
Certificate of Merger will be filed with the Secretary of State of Delaware. The
Merger will become effective upon the acceptance for filing of such Certificate
of Merger by the Secretary of State of Delaware (the "Effective Time", and such
date the "Effective Date"). It is currently expected that the Merger will occur
as soon as practicable following the approval of the Merger Agreement by the
stockholders of MRI and the stockholders of NMR. Either party may terminate the
Merger Agreement if the Effective Time has not occurred on or before December
31, 1996, provided that the failure of the Effective Time to occur on or before
such date does not result from a breach of the Merger Agreement by the
terminating party. See "Terms of the Merger -- Terminationand Amendment."

CONVERSION OF SHARES; TREATMENT OF OPTIONS, WARRANTS,
  CONVERTIBLE DEBENTURES AND OTHER RIGHTS; FRACTIONAL SHARES

    At the Effective Time, each issued and outstanding share of NMR Common Stock
will automatically convert into 0.6875 of a share of MRI Common Stock. As of the
date hereof, there are 6,310,571 issued and outstanding shares of NMR Common
Stock.


                                       38


<PAGE>


    Each warrant to acquire shares of NMR Common Stock (an "NMR Warrant") that
is outstanding and unexercised at the Effective Date shall, by virtue of the
Merger and without any action on the part of the holder thereof, and subject to
the other terms and conditions thereof, automatically be deemed to be
exercisable for that number of shares of MRI Common Stock the holder of such
Warrant would have received in the Merger, had such holder exercised such NMR
Warrant in full immediately prior to the Effective Date, and the price per share
of MRI Common Stock issuable after the Effective Date upon exercise of such NMR
Warrant shall equal the price per share of NMR Common Stock under such NMR
Warrant as in effect prior to the Effective Date divided by the Exchange Ratio.
MRI will be bound by and subject to all registration rights contained in each
NMR Warrant and such rights will apply against MRI with the same legal force and
effect as they applied against NMR prior to effectiveness of the Merger. After
the Effective Date, MRI shall issue to each holder of an NMR Warrant a new
warrant containing the foregoing terms and all other terms set forth in each NMR
Warrant.

    Pursuant to the Merger Agreement, each NMR stock option ("NMR Option")
outstanding on May 20, 1996 shall be deemed to constitute and shall
automatically be converted into stock options exercisable for shares of MRI
Common Stock ("New Options"). The number of shares of MRI Common Stock covered
by each New Option shall be the number of shares of MRI Common Stock which the
holder of the NMR Option would have received in the Merger had such holder
exercised the NMR Option in full immediately prior to the Effective Date,
without regard to vesting. The exercise price per share of MRI Common Stock
subject to a New Option shall equal the exercise price per share (subject to the
adjustments provided for in the NMR Option) of NMR Common Stock subject to the
corresponding NMR Option so converted divided by the Exchange Ratio. MRI shall
not be obligated to issue any shares of MRI Common Stock, until such time as the
shares of MRI Common Stock issuable upon exercise of New Options have been
registered with the SEC pursuant to an effective registration statement and
authorized for quotation on the Nasdaq National Market and for sale by any
appropriate state securities regulators, which MRI shall use its best efforts to
effect as promptly as practicable, but in no event more than 15 days after the
Effective Date.

    Additionally, under the Merger Agreement, the obligations of NMR under each
8% Convertible Subordinated Debenture due 2001 of NMR (an "NMR Debenture")
including, payment of the principal of and interest thereon that is outstanding
at the Effective Date shall, by virtue of the Merger and without any action on
the part of NMR or MRI, be assumed in full by, and become the obligations of
Subsidiary, as the surviving corporation, which shall comply after the Effective
Date with all requirements of the Indenture, dated as of July 1, 1986 (the
"Indenture") pursuant to which the Debentures were issued. Each NMR Debenture
that is outstanding at the Effective Date shall, by virtue of the Merger and
without any action on the part of the holder thereof, and subject to the other
terms and conditions thereof, automatically be deemed to be convertible for that
number of shares of MRI Common Stock that the holder of such NMR Debenture would
have received in the Merger had such holder converted such NMR Debenture in full
immediately prior to the Effective Date, and the price per share of MRI Common
Stock issuable after the Effective Date upon conversion of such NMR Debenture
shall equal the "conversion price" under such NMR Debenture in effect prior to
the Effective Date divided by the Exchange Ratio.

    NMR Warrants, NMR Options and NMR Debentures are sometimes referred to
collectively herein as "NMR Derivative Securities."

    On July 29, 1996, the closing sales price quoted on the Nasdaq National
Market for MRI Common Stock was $7.38 per share. If the Merger had occurred on
that date, the equivalent market value for each share of NMR Common Stock would
have been approximately $5.07 per share of NMR Common Stock.

    No fractional shares of MRI Common Stock will be issued in connection with
the Merger. In lieu of any fractional share of MRI Common Stock which any NMR
stockholder would otherwise be entitled to receive pursuant to the Merger or any
holder of a NMR Derivative Security would otherwise be entitled to receive upon
exercise of such NMR Derivative Security, MRI shall pay a cash adjustment in
respect of such fraction in an amount equal to the average last reported sales
price of MRI Common Stock on the Nasdaq National Market for the five (5) trading
days ended on the close of business on the second business day before the NMR
Meeting (the "Fair Market Value") multiplied by the fractional share interest to
which such holder would otherwise be entitled.

EXCHANGE OF CERTIFICATES

    Prior to the Effective Time, MRI shall designate its transfer agent (the
"Exchange Agent") to act as exchange agent in effecting the exchange of
certificates representing NMR Common Stock for certificates representing the


                                       39


<PAGE>


shares of MRI Common Stock into which such shares of NMR Common Stock have been
converted. After the Effective Date, the Exchange Agent shall send a letter of
transmittal to the holders of NMR Common Stock offering to exchange the
certificates representing such NMR Common Stock for certificates representing
shares of MRI Common Stock. From and after the Effective Time, each certificate
or instrument which, prior to the Effective Time, represented shares of NMR
Common Stock or NMR Warrants, NMR Options or NMR Debentures (collectively, "NMR
Derivative Securities") will be deemed to represent, as applicable, only the
right to receive certificates for shares of MRI Common Stock or the right to
acquire shares of MRI Common Stock in accordance with the terms of the Merger
Agreement, and the holder of each such certificate or instrument will cease to
have any rights with respect to the shares of NMR Common Stock formerly
represented thereby (in the case of certificates formerly representing shares of
NMR Common Stock) or with respect to the shares of NMR Common Stock issuable
upon exercise thereof (in the case of instruments formerly representing NMR
Derivative Securities), except as otherwise provided in the Merger Agreement or
by law.

REPRESENTATIONS, WARRANTIES AND COVENANTS

    The Merger Agreement contains certain representations and warranties by MRI,
Subsidiary and NMR, and also contains covenants of the parties with respect to
the conduct of their respective businesses pending the closing under the Merger
Agreement, including agreements (subject to certain exceptions) not to issue any
equity securities, not to pay any dividends or redeem or purchase any of its
securities and not to sell any material amount of their respective assets or
acquire any material assets, equity securities or businesses outside of the
ordinary course of business. In addition, each of the parties has agreed to
carry on its respective business only in the ordinary course and consistent with
past practice and to use all reasonable efforts to preserve intact its present
business organization and relationships with clients and others having business
dealings with it.

    There are no agreements or undertakings in the Merger Agreement on the part
of either MRI or NMR to indemnify the other following the Effective Time in the
event any representation or warranty made by either party to the other in the
Merger Agreement was not accurate at the time made. However, in the event the
Merger becomes effective, MRI and Subsidiary each agree to indemnify any person
who prior to the Effective Time is or was an officer, director, employee or
agent of MRI or NMR or Subsidiary against liability, claims or amounts paid in
settlement of any claim, suit or proceeding, including any liabilities arising
under or out of any state or Federal securities laws to the fullest extent
permitted by law, based in whole or in part on the fact that such person is or
was an officer, director, employee or agent of MRI or NMR or arising out of the
transactions contemplated by the Merger Agreement and, to the extent permitted
by law, advance expenses incurred to defend against such liabilities, claims or
amounts.

CONDITIONS PRECEDENT TO CONSUMMATION OF THE MERGER

    The obligation of the respective parties to the Merger Agreement to
consummate the Merger is subject to the approval of the Merger Agreement by the
stockholders of MRI and the approval of the Merger Agreement by the stockholders
of NMR. The obligations of the parties to consummate the Merger are also subject
to a number of other conditions, including the accuracy as of the closing date
of all material representations and warranties of the parties contained in the
Merger Agreement; the performance in all material respects of all covenants of
the parties contained in the Merger Agreement which are to be performed on or
before the closing date; the absence of any statute, rule, regulation or
governmental or judicial action which prohibits or restrains the transactions
contemplated by the Merger Agreement and the absence of certain suits,
investigations or changes in circumstances which would have a material adverse
effect on the transactions contemplated by the Merger Agreement; the delivery of
certain certificates and agreements by the parties and their respective officers
and directors, including the Non-Competition and Consulting Agreements (as such
terms are defined below); and the delivery of certain opinions by counsel to the
parties.

    The Merger Agreement also provides that MRI's obligation to consummate the
Merger is conditioned upon NMR's agreement not to modify the Rights Agreement
between NMR and American Stock Transfer & Trust Company establishing NMR's
stockholder rights plan (the "Rights Agreement"), except as contemplated by the
Merger Agreement, and to take such action as is necessary in order not to
trigger the rights under the Rights Agreement.

    The parties may waive compliance with any of the conditions to their
respective obligations to consummate the Merger.

NON-COMPETITION AND CONSULTING AGREEMENTS

    In connection with the Merger, Joseph G. Dasti, Chairman of the Board of
Directors, President and Chief Executive Officer of NMR and John P. O'Malley
III, Executive Vice President -- Finance, Chief Financial Officer and Secretary 
of NMR (the "Consultants") have entered into termination agreements (the
"Termination Agreements") and executed non-competition and consulting agreements
(the "Non-Competition and Consulting Agreements"). The Termination Agreements
between NMR and the Consultants provide for the termination of the Consultants'
existing employment agreements with NMR concurrent with the effectiveness of the
Merger in exchange for lump sum cash payments of $650,000 to Mr. Dasti and
$540,000 to Mr. O'Malley. The Termination Agreements and the lump sum payments
thereunder are conditioned on the effectiveness of the Non-Competition
and Consulting Agreements.

    Effectiveness of the Non-Competition and Consulting Agreements between MRI
and the Consultants is also a condition to consummation of the Merger and
consummation of the Merger is a condition to effectiveness of the
Non-Competition and Consulting Agreements. Pursuant to the Non-Competition and
Consulting Agreements, Mr. Dasti and Mr. O'Malley would be engaged for periods
of 12 months and 24 months, respectively, to provide consulting services to MRI
which are expected initially to focus on integrating NMR's business and
operations with those of MRI. Additionally, Mr. Dasti and Mr. O'Malley would
agree for periods of 18 and 24 months, respectively (the "Restrictive Period"),
not to directly or indirectly engage in any business or enterprise in the United
States which is competitive with the business conducted by MRI (the
"Non-Competition Covenant"). Additionally, during the applicable Restrictive
Period, each Consultant would be prohibited from soliciting for employment,
either on his own behalf or on behalf of another person or entity, any person
who is then employed by MRI or by any entity owned or otherwise affiliated with
MRI or inducing any person or entity engaged in business with MRI to reduce the
amount of business engaged in with MRI (the "Non-Solicitation Covenant"). In the
event the Consultant terminates the Non-Competition and Consulting Agreement
because of a material breach by MRI of any of the compensation and payment terms
provided for in the Non-Competition and Consulting Agreements, the
Non-Competition and Non-Solicitation Covenants will thereafter not apply to the
Consultants.

    The Non-Competition and Consulting Agreement between MRI and Mr. Dasti
provides for an initial term of one year commencing on the Effective Date of the
Merger, which term may be extended upon the mutual agreement of the parties;
however, MRI is under no obligation to renew the agreement. Mr. Dasti's
Non-Competition and Consulting Agreement would be terminable (i) by MRI "for
cause" in the event Mr. Dasti is convicted of a felony against MRI, and (ii) by
Mr. Dasti at any time after MRI materially breaches the compensation and payment
terms of the Non-Competition and Consulting Agreement and fails to correct such
breach within 10 days. In the event the Non-Competition and Consulting Agreement
is terminated by MRI for cause, Mr. Dasti's right to receive compensation and
all other rights pursuant to such agreement would terminate and MRI would have
no further obligation to Mr. Dasti other than payment of accrued and unpaid fees
and reimbursable expenses.

    Under the Non-Competition and Consulting Agreement, Mr. Dasti would receive
annual compensation of $133,000 for consulting services, together with
reimbursements of expenses for health benefits and approved business expenses.
Mr. Dasti may elect to defer such compensation for a period of up to six months.
In consideration for Mr. Dasti's agreement to comply with the Non-Competition
and Non-Solicitation Covenants, MRI would pay to Mr. Dasti a fee of $211,000
payable in 18 equal monthly installments, in advance. In addition, to induce Mr.
Dasti to enter into the Non-Competition and Consulting Agreement, MRI would
issue to Mr. Dasti at the closing of the Merger (i) five-year warrants to
purchase 40,000 shares of MRI Common Stock at an exercise price of $8.00 per
share and (ii) six year warrants to purchase 200,000 shares of MRI Common Stock
at an exercise price of $9.50 per share, and (iii) in exchange for his NMR
employee stock options, three (3) separate three year stock purchase warrants to
purchase 34,375, 68,750, and 34,375 shares of MRI Common Stock (subject to
adjustment in the event Mr. Dasti exercises options prior to the Effective Time)
at exercise prices of $9.27, $4.18, and $4.73, respectively. Such warrants would
contain certain rights to require MRI to register under the Securities Act the
resale of shares of MRI Common Stock received upon exercise of the warrants.

    The Non-Competition and Consulting Agreement between MRI and Mr. O'Malley
provides for an initial term of two years commencing on the Effective Date of
the Merger which term may be extended upon the mutual agreement of the parties;
however, MRI is under no obligation to renew the agreement. Mr. O'Malley's
Non-Competition and Consulting Agreement would be terminable (i) by MRI "for
cause" in the event Mr. O'Malley is convicted of a felony against MRI, and (ii)
by Mr. O'Malley (y) at any time after MRI materially breaches the compensation
and payment 


                                       41


<PAGE>


terms of the Non-Competition and Consulting Agreement and fails to correct such
breach within 10 days, or (z) 18 months after the Effective Date of the Merger.
In the event of the election by Mr. O'Malley to terminate the Non-Competition
and Consulting Agreement 18 months after the Effective Date, so long as he is
not in breach of the Non-Competition and Non-Solicitation Covenants therein, Mr.
O'Malley would be entitled to all payments under the Non-Competition and
Consulting Agreement as though the agreement had not been terminated. In the
event the Non-Competition and Consulting Agreement is terminated by MRI "for
cause", Mr. O'Malley's right to receive compensation and all other rights
pursuant to such agreement would terminate and MRI would have no further
obligation to Mr. O'Malley, other than for payment of accrued and unpaid fees
and reimbursable expenses. Mr. O'Malley's Non-Competition and Consulting
Agreement also provides that if Mr. O'Malley terminates the Agreement without
cause at any time prior to the period ending 18 months following the Effective
Date of the Merger, Mr. O'Malley would be entitled to continue to receive
compensation and benefits under the Agreement so long as he is not in breach of
the Non-Competition and Non-Solicitation Covenants, but the monthly amount of
such compensation would be reduced, until 18 months following the Effective
Date, by $11,111.

    Under the Non-Competition and Consulting Agreement, Mr. O'Malley would
receive annual compensation of $275,000 for consulting services, payable
monthly, in advance, together with reimbursement of expenses for health benefits
and approved business expenses. Mr. O'Malley may elect to defer such
compensation for a period of up to six months. In consideration of Mr.
O'Malley's agreement to comply with the Non-Competition and Non-Solicitation
Covenants, MRI would pay to Mr. O'Malley an annual fee of $275,000 payable in
equal monthly installments, in advance. Certain payments under Mr. O'Malley's
Non-Competition and Consulting Agreement will be secured by a letter of credit.
In addition, in order to induce Mr. O'Malley to enter into the Non-Competition
and Consulting Agreement, MRI would issue to Mr. O'Malley at the closing of the
Merger (i) five-year warrants to purchase 50,000 shares of MRI Common Stock at
an exercise price of $8.00 per share, and (ii) in exchange for his NMR employee
stock options, four (4) separate stock purchase warrants to purchase 10,313,
27,500, 41,250, and 34,375 shares of MRI Common Stock (subject to adjustment in
the event Mr. O'Malley exercises any employee stock options prior to the
Effective Time) at exercise prices of $4.00, $3.36, $4.18 and $4.73,
respectively. Such warrants would contain certain rights to require MRI to
register under the Securities Act the resale of shares of MRI Common Stock
received upon exercise of the warrants.

TERMINATION AND AMENDMENT

    The Merger Agreement may be terminated at any time prior to the Effective
Time: (i) by mutual written consent of the Boards of Directors of NMR and MRI;
(ii) by either MRI or NMR, as the case may be, if (A) any representation or
warranty made by the other party in the Merger Agreement shall not have been
true when made and would be reasonably likely to have a material adverse effect
on the party which made such representation or warranty or any covenant or
agreement made by the other party in the Merger Agreement shall not have been
performed or complied with, (B) any court or governmental body takes any action
restraining, enjoining or otherwise prohibiting the transactions contemplated by
the Merger Agreement and all appeals and means of appeal therefrom have been
reasonably exhausted, (C) the Effective Time shall not have occurred on or
before December 31, 1996, unless the failure of the Effective Time to occur on
or before such date is the result of a breach of the Merger Agreement by the
terminating party, (D) the Merger Agreement shall fail to receive the requisite
votes for approval and adoption by the stockholders of either NMR or MRI at
their respective stockholders' meetings or (E) any other condition to either
MRI's or NMR's obligations to effect the Merger have not been met.

    The Merger Agreement may be amended at any time prior to the effective date;
provided, however, that after MRI and NMR stockholder approval, no amendment may
be made which would reduce the amount of consideration payable to NMR
stockholders in the Merger.

EXPENSES OF THE MERGER

    MRI and NMR will pay their respective costs and expenses in connection with
the Merger, except under certain circumstances. The Merger Agreement provides
that expenses related to the drafting, preparing, printing, filing, and mailing
the Registration Statement, the Proxy Statement and all SEC and other regulatory
filing fees incurred in connection with the Registration Statement and the Proxy
Statement shall be allocated between MRI and NMR.

    It is anticipated that the costs and expenses of MRI and NMR in connection
with the Merger (including blue sky fees and fees payable to Dillon Read by MRI
and to Cowen by NMR) will be approximately $905,000 and $415,000, respectively.

FEES

    In the event that the Merger Agreement is terminated by either MRI or NMR as
a result of (i) a breach by the other party of any representation or warranty
contained in the Merger Agreement which would have or would be reasonably likely
to have a material adverse effect on such other party or (ii) the failure of the
other party to perform or comply with any covenant or agreement made by such
party, then such breaching party shall pay to the non-breaching party the sum of
$2,000,000 plus any fees or expenses incurred by the non-breaching party in
connection with the collection of such amount. In the event the Merger Agreement
is terminated by NMR or MRI for the sole reason that the Merger is not approved
by the stockholders of NMR or MRI, as applicable, then the party whose
stockholders did not approve the Merger shall pay to the other party, in
consideration of the time, effort and resources expended in connection with the
Merger transaction, $1,000,000 plus any fees or expenses incurred by such party
in connection with the collection of such amount.

NO SOLICITATION PROVISION AND FEE PAYABLE

    The Merger Agreement imposes certain limitations on the ability of MRI and
NMR to initiate, solicit, encourage or enter into a "Business Transaction",
which is defined to mean any merger, acquisition, consolidation, share exchange
or similar transaction having an aggregate value of $35 million or more, or any
sale, transfer, lease or other disposition of 50% or more of the assets or
capital stock of either MRI or NMR in a transaction or series of transactions.
Specifically, neither party may initiate, solicit, encourage or enter into a
Business Transaction at any time (the "No-Shop Period") between May 20, 1996 and
the earlier of (i) termination of the Merger Agreement by mutual consent of the
parties, by reason of a judicial order prohibiting consummation of the Merger
which is final and non-appealable or as a result of a party's breach of a
material representation, warranty or covenant, (ii) January 31, 1997, if the
Merger is not consummated by December 31, 1996 due to no fault of either party,
and (iii) three months following termination (but no later than January 31,
1997) if the Merger Agreement is not approved by the stockholders of MRI or NMR
or certain closing conditions cannot be met. However, neither MRI nor NMR are
prohibited from furnishing information to, or entering into discussions or
negotiations with, any person or entity in connection with an unsolicited
bonafide proposal by such person or entity to enter into a Business Transaction
if the Board of Directors of MRI or NMR (the "Target Company"), as the case may
be, determines in good faith that such action is required to comply with the
Board of Director's fiduciary duties to the stockholders imposed by the DGCL. In
such event, the Target Company would also be required to notify the other party
that it is furnishing information and, to the extent not prohibited by law,
disclose to the other party the relevant terms of any such proposals received.
Additionally, the foregoing restrictions would not prevent the Target Company
from complying with its obligations under Federal tender offer laws and
regulations.

    The Merger Agreement also provides that if the Target Company publicly
announces its intention to or enters into an agreement providing for a Business
Transaction during the No-Shop Period, the Target Company would be required to
pay to the other party, in consideration of the time, effort and resources
expended in connection with the Merger, $2,000,000 (less any amounts paid by the
Target Company to the other party, pursuant to other termination provisions
under the Merger Agreement), plus any fees incurred in connection with
collecting such amount.

INTEREST OF CERTAIN PERSONS IN THE MERGER

    In considering the recommendation of the MRI and NMR Boards of Directors
with respect to the Merger and the Merger Agreement, stockholders of MRI and NMR
should be aware that certain members of NMR's management have certain interests
in the Merger that are in addition to the interests of the stockholders of NMR.
See "Terms of the Merger--Non-Competition and Consulting Agreements." In
addition, 712 Advisory Services, Inc. ("Advisory Services"), a financial
advisory services company owned by Gary N. Siegler, Chairman of the Board of
Directors of MRI, has been engaged by MRI to act as MRI's financial advisor in
connection with the Merger. Advisory Services has assisted MRI in negotiating
and structuring the Merger and provided significant other advice in connection
with preparing this Joint Proxy Statement/Prospectus, performing due diligence,
and other matters pertaining to the Merger, for which it will receive a cash
financial advisory fee of $175,000 and five-year warrants to purchase 120,000
shares of MRI Common Stock at an exercise price of $9.00 per share
(collectively, the "MRI Fee"). Payment of the MRI Fee is conditioned upon
consummation of the Merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

    The following is a general summary of certain material Federal income tax
consequences under the Internal Revenue Code of 1986, as amended (the "Code"),
of the Merger to NMR and the holders of NMR Common Stock.


                                       43


<PAGE>


This discussion does not consider all the Federal tax consequences of the Merger
that may be relevant to, or may materially affect, individual NMR stockholders
or employees, including, without limitation, holders of shares acquired upon
exercise of NMR Derivative Securities or in compensatory transactions. This
summary is based on certain provisions of the Code, final, temporary and
proposed Treasury Regulations promulgated thereunder (the "Regulations") and
administrative and judicial interpretations thereof, all in effect as of the
date hereof and all subject to change (possibly on a retroactive basis) at any
time. Any such changes in legislative, judicial or administrative actions or
interpretations could alter or significantly modify the tax analysis of the
issues set forth below.

    At the Closing and in accordance with the Merger Agreement, NMR will receive
an opinion of NMR's counsel, McCarter & English, with respect to certain Federal
income tax consequences of the Merger to NMR and the holders of NMR Common
Stock. This opinion, which is referred to herein as the "Tax Opinion", will not
be binding on the Internal Revenue Service ("IRS"). In rendering the Tax
Opinion, such counsel will rely on certain representations made or to be made by
certain corporate officers of NMR, Subsidiary and MRI including representations
that (i) the fair market value of the shares of MRI Common Stock to be received
by each stockholder of NMR in connection with the Merger will be approximately
equal to the fair market value of the shares of NMR Common Stock surrendered in
exchange therefor in the Merger, (ii) there is no plan or intention on the part
of the stockholders of NMR who own 5 percent or more of NMR Common Stock and, to
the best of the knowledge of the management of NMR, there is no plan or
intention on the part of the remaining stockholders of NMR to sell, exchange or
otherwise dispose of a number of shares of MRI Common Stock to be received by
them in the Merger that would reduce the aggregate value of such MRI Common
Stock held by the NMR stockholders to less than 50% of the aggregate value of
the outstanding NMR Common Stock immediately prior to the Merger, (iii) no
stockholder of NMR will directly or indirectly receive from MRI any
consideration in the Merger in respect of such stockholder's NMR Common Stock
other than MRI Common Stock, excluding payments of cash to NMR stockholders in
lieu of fractional shares of MRI Common Stock, (iv) MRI has no plan or intention
to reacquire any of the shares of MRI Common Stock to be issued to the
stockholders of NMR pursuant to the Merger and MRI is under no contractual
obligation and has no contractual right to reacquire any such shares of MRI
Common Stock, (v) Subsidiary will continue the historic business of NMR or use a
significant portion of NMR's business assets in a business, (vi) the liabilities
of NMR assumed by Subsidiary and the liabilities to which the assets transferred
to Subsidiary in the Merger are subject were incurred by NMR in the ordinary
course of business, (vii) the payment of cash in lieu of fractional shares of
MRI Common Stock is solely for the purpose of avoiding the expense and
inconvenience to MRI of issuing fractional shares and does not represent
separately bargained for consideration, (viii) the total cash consideration that
will be paid in the Merger to NMR stockholders in lieu of fractional shares of
MRI Common Stock will not exceed one percent (1%) of the aggregate consideration
that will be issued to NMR stockholders with respect to their shares of NMR
Common Stock surrendered in the Merger, (ix) none of the compensation for
services rendered to be received by any employee of NMR who is also a
stockholder of NMR is consideration for, or allocable to, such
stockholder/employee's shares of NMR Common Stock exchanged in the Merger, (x)
there is no intercorporate indebtedness existing between NMR and MRI that was
issued, acquired or will be settled at a discount in connection with the Merger,
(xi) no two parties to the transaction are investment companies as defined in
Code Section 368(a)(2)(F)(iii), (xii) NMR is not under the jurisdiction of a
court in a Title 11 or similar case within the meaning of Code Section
368(a)(3)(A), (xiii) the fair market value of the assets of NMR transferred to
Subsidiary will equal or exceed the sum of NMR liabilities assumed by Subsidiary
in the Merger, plus the amount of liabilities, if any, to which the transferred
assets are subject, (xiv) the Merger is based upon valid business purposes
unrelated to the avoidance of Federal income taxes and will comply in all
respects with the laws of the states of incorporation of the corporations
involved in the Merger, (xv) in the Merger, the stockholders of NMR will
exchange for voting stock of MRI an amount of voting stock of NMR which
constitutes control of NMR under Section 368(c) of the Code, (xvi) Subsidiary
will acquire at least 90 percent of the fair market value of the net assets and
at least 70 percent of the fair market value of the gross assets held by NMR
immediately prior to the Merger (for purposes of this representation, amounts
paid by NMR to stockholders who receive cash or other property, assets of NMR
used to pay its reorganizational expenses, and all redemptions and distributions
(except for regular dividends) completed by NMR immediately prior to the Merger
are included as assets of NMR held immediately prior to the Merger), (xvii)
prior to the transaction, MRI will be in control of Subsidiary within the
meaning of Section 368(c) of the Code, (xviii) following the Merger, Subsidiary
will not issue additional shares of its stock in a manner that would result in
MRI losing control of Subsidiary within the meaning of Code Section 368(c),
(xix) MRI has no plan or intention to liquidate Subsidiary, to merge Subsidiary
with and into another corporation, to sell or otherwise dispose


                                       44


<PAGE>


of the stock of Subsidiary or to cause Subsidiary to sell or otherwise dispose
of any of the assets of NMR acquired in the Merger, other than assets located in
NMR's Bel Air, Maryland and Elgin, Illinois centers and except for dispositions
made in the ordinary course of business or transfers described in Code Section
368(a)(2)(c), (xx) MRI, Subsidiary, NMR and the stockholders of NMR will pay
their respective expenses, if any, incurred in connection with the transaction,
and (xxi) no stock of Subsidiary will be issued in the Merger.

    The Tax Opinion, which will be limited to the Federal income tax
consequences enumerated below, shall be as follows:

       1. The Merger will be a reorganization within the meaning of Code
    Sections 368(a)(1)(A) and 368(a)(2)(D) and NMR will be a party to such
    reorganization within the meaning of Section 368(b) of the Code.

       2. No gain or loss will be recognized  for Federal  income tax purposes
    by NMR on the transfer of its assets to Subsidiary  and the  assumption by
    Subsidiary  of NMR's  liabilities  pursuant to the Merger.  Code  Sections
    361(a) and 357(a).

       3. No gain or loss will be recognized by the stockholders of NMR whose
    shares of NMR Common Stock are converted solely into shares of MRI Common
    Stock in connection with and pursuant to the Merger. CodeSection 354(a).

       4. The tax basis of the shares of MRI Common Stock received by the
    stockholders of NMR in the Merger will be equal, in each instance, to the
    tax basis of the shares of NMR Common Stock surrendered by such stockholders
    in exchange therefor. Code Section 358(a).

       5. The holding period of the shares of MRI Common Stock received by the
    stockholders of NMR in connection with the Merger will include, in each
    instance, the period during which the shares of NMR Common Stock surrendered
    in exchange therefor were held by such stockholders if, and to the extent
    that, the shares of NMR Common Stock were capital assets in the hands of the
    NMR stockholders on the Effective Date of the Merger. Code Section 1223(1).

       6. The NMR stockholders receiving cash in lieu of fractional shares of
    MRI Common Stock will be treated as if such fractional shares had been
    issued by MRI and then subsequently redeemed by MRI and will be taxed on any
    resulting gain in an amount which shall not exceed the amount of the cash
    received. Code Section 356(a). Whether the cash received by such NMR
    stockholders in lieu of fractional shares of MRI Common Stock is
    characterized as a dividend or as a payment in exchange for the shares of
    NMR Common Stock will depend on whether the distribution of cash to such
    stockholders, when viewed as part of the reorganization as a whole and as a
    redemption by MRI, and in light of tax principles analogous to those set
    forth in Code Section 302(b), more closely resembles a dividend distribution
    or a payment in exchange for shares of NMR Common Stock.

    A successful IRS challenge to the status of the Merger as a reorganization
within the meaning of Code Section 368 would result in each NMR stockholder
recognizing gain or loss with respect to each share of NMR Common Stock
surrendered equal to the difference between the stockholder's tax basis in such
share and the fair market value, as of the time of the Merger, of the MRI Common
Stock received in exchange therefor. Even if the Merger qualifies as a
reorganization within the meaning of Section 368(a)(1)(A) and Section
368(a)(2)(D) of the Code, a recipient of shares of MRI Common Stock may
recognize income, gain or loss to the extent such shares are considered to have
been received in exchange for services or property (i.e. for consideration other
than solely shares of NMR Common Stock).

    The Tax Opinion specifically excludes any reference to the tax consequences
of the Merger that may relate to any holder of NMR Derivative Securities or
other rights to acquire shares of NMR Common Stock, including, without
limitation, the tax consequences of the acceleration of the right to exercise
any such rights by the holders thereof pursuant to the Merger. Holders of any
NMR Derivative Securities or other rights to acquire NMR Common Stock are
strongly advised to consult with their tax advisors with respect to the tax
consequences of the Merger that may relate to them.

    THE FOREGOING IS A SUMMARY OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE
MERGER AND DOES NOT SET FORTH ALL THE ASSUMPTIONS, QUALIFICATIONS AND
LIMITATIONS REFERENCED IN THE TAX OPINION. NMR STOCKHOLDERS SHOULD CONSULT WITH
THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGER WITH RESPECT
TO THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING, WITHOUT LIMITATION, THE
APPLICABILITY OF FOREIGN, STATE AND LOCAL LAWS.

ACCOUNTING TREATMENT

    MRI intends to treat the Merger as a purchase, as such term is used under
generally accepted accounting principles, for accounting and financial reporting
purposes. Under the purchase method of accounting, assets and liabilities of NMR
would be recorded at their fair value at the Effective Time, with the excess of
the consideration to be paid by MRI pursuant to the Merger over NMR's net
tangible and identifiable intangible assets being recorded as goodwill. See "MRI
and NMR Unaudited Pro Forma Combined Financial Statements."

RESTRICTIONS ON RESALE OF MRI COMMON STOCK BY FORMER NMR STOCKHOLDERS

    MRI has registered under the Securities Act the shares of MRI Common Stock
which holders of shares of NMR Common Stock which are outstanding at the
Effective Time will be entitled to receive upon consummation of the Merger.
Those stockholders of NMR who are not deemed to be "affiliates" of NMR at the
time of the Merger may freely sell the shares of MRI Common Stock they receive
in the Merger. An "affiliate" includes any person who, directly or indirectly,
controls, is controlled by, or is under common control with, NMR at the time the
Merger is submitted to a vote of the stockholders of NMR.

    Stockholders of NMR who are deemed to be "affiliates" of NMR may resell the
shares of MRI Common Stock received upon consummation of the Merger in
compliance with Rule 145 promulgated under the Securities Act, pursuant to an
effective registration statement under the Securities Act or in transactions
exempt from registration, and may not use this Joint Proxy Statement/Prospectus
to effect resales of the shares of MRI Common Stock they receive. Rule 145, as
currently in effect, imposes restrictions on the manner in which such affiliates
may make resales and also on the volume of resales which such affiliates, and
others with whom they may act in concert, may make in any three month period.

APPRAISAL RIGHTS

    MRI STOCKHOLDERS. Appraisal rights are not available under Delaware law to
MRI's stockholders in connection with the Merger.

    NMR STOCKHOLDERS. Appraisal rights are not available under Delaware law to
NMR's stockholders in connection with the Merger.

                        DESCRIPTION OF MRI CAPITAL STOCK

    The authorized capital stock of MRI consists of 20,000,000 shares of MRI
Common Stock, par value $.01 per share, and 100,000 shares of Preferred Stock,
par value $.01 per share ("Preferred Stock"). As of July 1, 1996, MRI had
outstanding 8,866,489 shares of MRI Common Stock and 128 shares of Preferred
Stock.

COMMON STOCK

    The holders of outstanding shares of MRI Common Stock are entitled to
receive dividends out of assets legally available therefor at such times and in
such amounts as the Board of Directors may, from time to time, determine. Each
stockholder is entitled to one vote for each share of MRI Common Stock held by
such stockholder. MRI's Certificate of Incorporation does not provide for
cumulative voting. The MRI Common Stock is not entitled to preemptive rights and
is not subject to redemption. Upon liquidation, dissolution, or winding-up of
MRI, the assets legally available for distribution to stockholders are
distributed ratably among the holders of MRI Common Stock outstanding at that
time after payment of liquidation preferences, if any, on any outstanding
Preferred Stock. Each outstanding share of MRI Common Stock is fully paid and
nonassessable.

PREFERRED STOCK

    MRI's Certificate of Incorporation provides that MRI may, without further
action by MRI's stockholders, issue shares of Preferred Stock in one or more
series. The Board of Directors is authorized to establish from time to time the
number of shares to be included in any such series and to fix the relative
rights and preferences of the shares of any such series, including without
limitation dividend rights, dividend rates, voting rights, redemption rights and
terms, liquidation preferences and sinking fund provisions. The Board of
Directors may authorize and issue Preferred Stock with voting or conversion
rights that could adversely affect the voting power or other rights of the
holders of MRI Common Stock. In addition, the issuance of Preferred Stock could
have the effect of delaying or preventing a change in control of MRI.

    As part of the total shares of authorized Preferred Stock, MRI's Certificate
of Incorporation designates two series of Preferred Stock of MRI consisting of
2,000 shares of Series A Preferred Stock (the "Series A Preferred 


                                       46


<PAGE>


Stock") and 2,000 shares of Series B Preferred Stock (the "Series B Preferred
Stock", and together with the Series A Preferred Stock, the "Designated
Preferred Stock"). Each issued and outstanding share of Designated Preferred
Stock is entitled to receive, when, as and if declared by the Board of Directors
out of funds legally available therefor annual dividends which shall be
cumulative at the rate of 9% of the applicable liquidation preference. No
dividends have been declared by MRI's Board of Directors and none are expected
to be. Except as otherwise provided by law, the Designated Preferred Stock shall
have no voting rights. The Designated Preferred Stock shall be redeemable, in
whole or in part, at the option of MRI, at any time from time to time, at a
redemption price (the "Redemption Price") per share equal to the sum of (x) the
applicable liquidation preference and (y) any accrued and unpaid dividends on
the Designated Preferred Stock. The Designated Preferred Stock is also subject
to mandatory redemption in the event MRI sells, disposes or transfers any shares
of common stock of Maternity Resources, Inc. ("Maternity Inc.") or all or
substantially all of the assets of Maternity Inc. not in the ordinary course of
business, in which case the Designated Preferred Stock shall be redeemed at the
Redemption Price solely out of the net proceeds from such sale after payment of
all liabilities of Maternity Inc. MRI did not realize any net proceeds from its
disposition of the assets of Maternity Inc. in 1995; therefore, MRI expects the
Designated Preferred Stock to be redeemed or cancelled without the payment of
any material amounts to the holders of the Designated Preferred Stock. MRI has
no present plans to issue any additional shares of Preferred Stock. See
"Information Concerning Medical Resources, Inc. -- Certain Relationships and
Related Party Transactions."

SHARES ELIGIBLE FOR FUTURE SALE

    On July 29, 1996, an aggregate 2,819,625 shares of MRI Common Stock were
issuable upon exercise or conversion of MRI Derivative Securities, of which
2,699,625 shares have been registered by MRI for resale under the Securities
Act. In addition, in connection with the Merger, MRI has agreed to register for
resale 1,305,156 shares of MRI Common Stock issuable upon exercise or conversion
of NMR Derivative Securities. Upon such registration, these shares not held by
affiliates of NMR will become freely tradeable and transferable without
restriction. Exercise or conversion of a substantial amount of the MRI
Derivative Securities or the NMR Derivative Securities following the Merger
could adversely affect the market price of the MRI Common Stock due to the large
number of shares issuable upon exercise of such securities in comparison to the
number of shares of MRI Common Stock presently outstanding.

    Upon completion of the Merger, there will be approximately 13,205,006
outstanding shares of MRI Common Stock (assuming no exercise or conversion of
outstanding MRI Derivative Securities or NMR Derivative Securities prior to the
Effective Time). Of these shares, approximately 9,316,794 will be freely
transferable and tradable without restriction or further registration under the
Securities Act, except for any shares acquired by any affiliates of MRI, or by
affiliates of NMR pursuant to the Merger, which will be subject to the resale
limitations of Rule 144 promulgated under the Securities Act. In general, under
Rule 144 as currently in effect, affiliates of MRI would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of one percent of the number of shares of MRI Common Stock then
outstanding or the average weekly trading volume of the MRI Common Stock during
the four calendar weeks preceding the filing of a Form 144 with respect to such
sale. Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about MRI. MRI is unable to estimate accurately the number of shares that will
be sold under Rule 144 since this will depend in part on the market price for
the MRI Common Stock, the personal circumstances of the sellers and other
factors.

    MRI has also granted to holders of 958,571 shares of MRI Common Stock
certain rights to have the resale of such shares registered under the Securities
Act. In the event these registration rights are exercised, these shares would
become freely tradable and transferable without restriction.

TRANSFER AGENT

    The transfer agent and registrar of MRI Common Stock is American Stock
Transfer & Trust Company, 40 Wall Street, New York, New York 10005.

             COMPARISON OF RIGHTS OF STOCKHOLDERS OF MRI AND NMR

    At the Effective Time, stockholders of NMR will become stockholders of MRI.
Set forth below is a comparison of the terms of the MRI Common Stock and the
terms of NMR Common Stock, as well as a summary of other material differences
between the rights of holders of MRI Common Stock and the rights of holders of
NMR Common Stock. 


                                       47


<PAGE>


This summary does not purport to be complete and is qualified in its entirety by
reference to the MRI's Certificate of Incorporation and Bylaws, and NMR's
Certificate of Incorporation and Bylaws. See "Description of MRI Common Stock."

TERMS OF COMMON STOCK

    The rights of holders of MRI Common Stock are nearly identical to the rights
of holders of NMR Common Stock. The holders of MRI Common Stock and NMR Common
Stock each have the same rights with respect to dividends, voting, and
liquidation. In addition, MRI Common Stock and NMR Common Stock are quoted on
the Nasdaq National Market.

AMENDMENTS TO THE CERTIFICATE OF INCORPORATION

    Under the DGCL, an amendment to a corporation's certificate of incorporation
requires the affirmative vote of the holders of a majority of the outstanding
shares of the corporation entitled to vote thereon and a majority of the
outstanding shares of each class entitled to vote thereon as a class, unless the
corporation's certificate of incorporation provides for a higher percentage.
Holders of the outstanding shares of a class, or series of a class, shall be
entitled to vote as a class with respect to any amendment which would increase
or decrease the aggregate number of authorized shares of such class or series,
increase or decrease the par value of the shares of such class or series, or
alter or change the powers, preferences or special rights of such shares so as
to adversely affect such holders. Neither the Certificate of Incorporation nor
Bylaws of either MRI or NMR alter the procedures set forth in the DGCL for
effecting an amendment to either company's respective Certificate of
Incorporation.

AMENDMENT TO BYLAWS

    Under the DGCL, stockholders of a Delaware corporation have the power to
adopt, amend or repeal the bylaws of the corporation. Such action may be taken
by the stockholders at an annual or special meeting at which a quorum is
present. The Certificate of Incorporation of NMR provides that the Board of
Directors shall have the power to adopt, amend or repeal the Bylaws of NMR,
although this provision does not divest or limit the power conferred upon NMR
stockholders by the DGCL.

    The Bylaws of MRI authorize the Board of Directors of MRI or MRI's
stockholders to adopt, amend or repeal the MRI Bylaws.

DIRECTORS

    Under the Certificate of Incorporation of NMR, the number of directors is to
be fixed by or in the manner provided in NMR's Bylaws. NMR's Bylaws provide that
the number of directors of NMR shall be between five (5) and thirteen (13) as
determined from time to time by the Board. MRI's Bylaws permit the Board of
Directors by resolution to fix the number of directors. The DGCL provides that
the number of directors of a Delaware corporation is to be fixed by or in the
manner provided in the corporation's bylaws unless otherwise fixed in the
corporation's certificate of incorporation.

VACANCIES AND NEWLY CREATED DIRECTORSHIPS

    The DGCL provides that, unless otherwise provided in the corporation's
certificate of incorporation or bylaws, vacancies and newly created
directorships resulting from an increase in the authorized number of directors
may be filled by a majority of the directors then in office, although less than
a quorum, or by the sole remaining director; provided, that if the holders of
any class or series are entitled to elect one or more directors, vacancies and
newly created directors of such class or series shall be filled by a majority of
the directors elected by such class or series then in office, or by the sole
remaining director so elected.

    The Bylaws of MRI and NMR permit vacancies and newly created directorships
to be filled in the manner set forth in the DGCL, and further state that if no
directors are in office, any officer or stockholder may call a special meeting
of stockholders at which such vacancies may be filled.

REMOVAL OF DIRECTORS

    The DGCL permits the removal of any or all directors, with or without cause,
by the holders of a majority of the shares of the corporation entitled to vote
at an election of directors, except that (i) if the board of directors has been
classified into classes, such removal may only be for cause; (ii) if the
corporation has cumulative voting, no director may be removed without cause if
the votes cast against removal would be sufficient to elect such director if
voted


                                       48


<PAGE>


cumulatively at an election of the entire board or the entire class of directors
of which he is a member; and (iii) when the certificate of incorporation
provides that holders of shares of a class or series are entitled to elect one
or more directors, any director so elected may be removed without cause only by
the applicable vote of such holders.

    The Bylaws of MRI and NMR also permit the removal of any and all directors
with or without cause by a majority of the shares entitled to vote at an
election of directors.

    A Delaware corporation may declare and pay dividends to its stockholders
only out of its surplus, or if there shall be no surplus, out of its net profits
for the fiscal year in which the dividend is declared and/or the preceding
fiscal year. The DGCL defines a corporation's surplus as the amount by which its
net assets exceeds the capital of the corporation. Under the DGCL, net assets
means the amount by which a corporation's total assets exceeds its total
liabilities. The respective Certificates of Incorporation of MRI and NMR do not
impose any restriction on the payment of dividends.

POWER TO CALL SPECIAL MEETING OF STOCKHOLDERS

    Under the DGCL, special meetings of stockholders may be called by the board
of directors or such other person or persons as may be authorized in the
certificate of incorporation or the bylaws. Neither MRI's nor NMR's respective
Certificates of Incorporation contain provisions relating to special meetings of
stockholders. MRI's Bylaws provide that special meetings may be called by the
directors or any officer instructed by the directors to call the meeting. NMR's
Bylaws provide that special meetings may be called by the Chairman of the Board,
if any, or the President, and shall be called by the President or Secretary at
the request in writing of a majority of the Board of Directors or of the
stockholders owning a majority of the issued and outstanding shares entitled to
vote.

STOCKHOLDER ACTION WITHOUT A MEETING

    The DGCL provides that, unless otherwise provided in the certificate of
incorporation, any action required or permitted to be taken at any meeting of
stockholders may be taken without a meeting if a written consent setting forth
the action so taken is signed by the holders of outstanding stock having not
less than the minimum number of votes that would be necessary to authorize or
take such action at a meeting at which all shares entitled to vote thereon were
present and voted. MRI's Certificate of Incorporation does not prohibit
stockholder action without a meeting. NMR's Certificate of Incorporation
prohibits action by the stockholders of NMR without a meeting of stockholders.

of seven members, each to hold office (subject to MRI's Bylaws) until the next
annual meeting or until his respective successor is elected and qualified. In
the case of a vacancy, a director will be appointed by a majority of the
remaining directors then in office to serve the remainder of the term left
vacant. Directors do not receive any fees for attending Board meetings.
Directors are entitled to receive reimbursement for travelling costs and other
out-of-pocket expenses incurred in attending Board meetings. During the fiscal
year ended December 31, 1995 ("fiscal 1995"), the Board of Directors held 12
meetings (11 of which were by written consent in lieu of a meeting). All

committees of which they were members that were held while they were serving on
the Board or such committee.

     The Board of Directors has designated a Stock Option Committee, consisting
of Stephen M. Davis and Gary L. Fuhrman, which makes all decisions with respect

Acquisition") of Maternity Inc., a Delaware corporation formed by the partners
of Maternity Retail Partners L.P. and Kik Kin L.P. The Maternity Acquisition was
consummated pursuant to a Stock Purchase Agreement (the "Purchase Agreement")
dated as of February 24, 1995 by and among MRI, Maternity Inc. and the other
parties named therein (the "Sellers"). Pursuant to the Purchase Agreement, MRI
acquired (i) 100% of the issued and outstanding common stock of Maternity Inc.
from the Sellers in exchange for an aggregate of 480,000 shares of MRI Common
Stock and (ii) 100% of the issued and outstanding shares of Series B and Series
C Preferred Stock of Maternity Inc. from the holders thereof in exchange for
shares of MRI's Series A Preferred Stock and Series B Preferred Stock. Messrs.
Gary N. Siegler and Peter M. Collery, controlling persons of the Sellers, are
Chairman and a former Director of MRI, respectively, and principal stockholders
of MRI. An independent committee, comprised of Gary Fuhrman and John Josephson,
were appointed to structure and negotiate the terms of the Maternity Acquisition
with Maternity Inc.'s negotiating team of senior executive officers. The
independent committee was authorized to retain professional advisors and with
respect thereto engaged Howard Lawson & Co. ("HL&C") as its financial advisor.
HL&C rendered to the independent committee its written opinion that the terms of
the Maternity Acquisition were fair from a financial point of view to all of the
stockholders of MRI. The independent committee subsequently recommended to MRI
that it consummate the Maternity Acquisition at which time the Board of
Directors of MRI authorized the same.

     MRI pays a financial advisory fee to Advisory Services, the sole
stockholder of which is Mr. Siegler, for extensive financial advisory services
such firm renders on behalf of MRI and its subsidiaries. Such advisory fee
amounted to $225,000 for fiscal 1995.

     Werbel McMillin & Carnelutti, a law firm in which Mr. Davis, a Director, is
a partner, performed legal services for MRI during fiscal 1995.

INDEMNIFICATION OF OFFICERS AND DIRECTORS

     NMR has entered into separate indemnification agreements with each of its
officers that could require NMR, among other things, to indemnify its officers
against certain liabilities that may arise by reason of their status or service
as officers and to advance expenses incurred by them as a result of any
proceeding against them as to which they could be indemnified.

     In addition, NMR's Bylaws provide that NMR shall indemnify its officers and
directors made, or threatened to be made, a party to any action (other than an
action by or in the right of NMR) by reason of the fact that such individual is
or was a director or officer of NMR against liabilities and reasonable expenses
incurred in connection with such action if such person acted in good faith and
in a manner reasonably believed to be in or not opposed to the best interests of
the corporation, and with respect to any criminal proceedings, had no reasonable
cause to believe that such conduct was unlawful. NMR's Bylaws also provide that
NMR shall, with certain exceptions, indemnify its officers and directors against
reasonable expenses incurred in connection with any action by or in the right of
NMR if such person acted in good faith and in a manner reasonably believed to be
in or not opposed to the best interests of the corporation. Under NMR's Bylaws,
NMR must also indemnify its directors and officers against reasonable expenses
if such person is successful in the defense of any action of the nature
described above.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of NMR pursuant
to the foregoing provisions, or otherwise, NMR has been advised that in the
opinion of the SEC, such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable.

EMPLOYMENT AGREEMENTS

     NMR has entered into executive employment agreements with Messrs. Dasti and
O'Malley which expire on June 20, 2000 and provide for annual base salaries in
amounts of $225,000 and $175,000, respectively. Pursuant to the contracts,
Messrs. Dasti and O'Malley are entitled to receive quarterly bonus payments
calculated as a percentage of NMR's consolidated quarterly pre-tax income (as
defined in the agreements) as follows:

PTI in excess of $1,125,000 ...................................           1.65%             1.35%
</TABLE>

     Each of the employment agreements of Messrs. Dasti and O'Malley provides
that if the executive is terminated without cause, he shall be entitled to
receive severance pay equal to his base salary and bonus for the remainder of
the term of his contract. In addition, he would be entitled to continued
participation in NMR benefit plans until the earlier of (i) the expiration date
of his contract or (ii) the date he becomes employed by another company
providing similar benefits. In the event that the executive is terminated for
cause, he is not entitled to receive any monetary compensation under his
employment agreement beyond the date his employment is terminated.

     Each of the employment agreements also provides that if, following a change
of control (as defined in the agreements) of NMR, NMR, among other things,
assigns to the executive duties inconsistent with his position, materially
reduces his powers or functions, fails to provide annual salary increases
consistent with past practices or requires the executive to change his place of
employment, then the executive will have the right to terminate his employment
agreement. In such an event, the executive would be entitled to receive the same
severance pay as he would receive in the event his employment is terminated
without cause.

     In the event either executive terminates his employment agreement for
cause, any stock purchase options held by him issued pursuant to any stock
option plan of NMR would, to the extent permissible, become immediately vested
and exercisable. If the vesting of such options is not permitted, he would be
entitled to receive a five-year warrant immediately exercisable for the same
number of shares of NMR Common Stock subject to such options and exercisable at
the same per share exercise price. The executive would also be entitled in
certain instances to have the resale of the shares subject to the warrant
registered under the Securities Act.

     If the Merger is consummated, each of the foregoing employment agreements
would be terminated and Messrs. Dasti and O'Malley would enter into
Non-Competition and Consulting Agreements with MRI. See "Terms of the
Merger--Non-Competition and Consulting Agreements."

DIRECTOR AND OFFICER SECURITIES REPORTS

     The Federal securities laws require NMR's directors and executive officers,
and persons who own more than 10% of a registered class of NMR's equity
securities, to file with the SEC reports of changes in ownership of any equity
securities of NMR. Copies of such reports are required to be furnished to NMR.
To NMR's knowledge, based solely on a review of the copies of such reports
furnished to NMR, all persons subject to these reporting requirements filed the
required reports on a timely basis during the 1996 fiscal year.

CERTAIN TRANSACTIONS

     Ten of the operational diagnostic imaging systems owned by NMR at March 31,
1996 have been installed in offices leased by professional corporations whose
principal is Dr. David L. Bloom, who is also a director of NMR. These agreements
in general, provide for the payment to NMR of a periodic fixed fee, a fee based
upon the number of scans performed and a billing charge. Local radiologists are
under contract with these professional corporations pursuant to which such local
radiologists serve as the professional staff at the center and read the scans
produced at the center for a fee. Under the agreements, NMR is obligated to make
the necessary leasehold alterations or site improvements at each installation
for the diagnostic imaging systems, and provide the furniture, fixtures, and
furnishings necessary for the operation of the office. NMR is also obligated to
provide all the ancillary supplies and equipment used by the diagnostic imaging
systems and for arranging and paying for maintenance of the diagnostic imaging
systems. NMR also provides consultation with respect to the financial management
of the center, including billing and collecting fees. All fees are collected by
the physician professional corporations; however, NMR has the contractual
responsibility to maintain all financial and other records and prepare and
transmit bills. Pursuant to the foregoing agreements, NMR billed affiliated
professional corporations, net of contractual adjustments, $13,431,954 and
$14,784,092 during the fiscal years ended March 31, 1996 and 1995, respectively.
See "Director Compensation" above.

     On January 21, 1992, the Board of Directors authorized NMR to enter into an
agreement with Seaboard to provide advisory services to NMR in exchange for a
warrant to purchase 100,000 shares of NMR's Common Stock at an exercise price of
$8.00 per share through February 6, 1997, subject to vesting as services are
provided. NMR's consulting agreement with Seaboard expired on February 7, 1995.
In addition, NMR granted rights to certain persons who are shareholders of
Seaboard, including Mr. Zappala, a Director of NMR, to have the resale of the
shares of NMR Common Stock issuable on exercise of warrants held by such persons
registered under the Securities Act at the expense of such persons.

                      GOVERNMENT REGULATION OF MRI AND NMR

GENERAL

     Various Federal and state statutes and regulations affect virtually all
aspects of MRI's and NMR's operations. These include statutes intended to
facilitate healthcare planning by placing limitations on the purchase of medical
equipment and other capital expenditures and by seeking to contain healthcare
costs within the Medicare and Medicaid reimbursement programs. Federal and state
statutes also seek to prohibit or limit referrals of patients to facilities in
which the referring physician has an ownership interest. These statutes and
regulations, as well as the reimbursement policies of the various state and
Federal government programs and other aspects of government regulation of the
healthcare industry are subject to amendment, revision and further
interpretation from time to time. These amendments, revisions and
interpretations could change the regulatory environment relating to MRI's and
NMR's operations and the programs under which physicians and others are
reimbursed for diagnostic imaging procedures, and thereby could have a material
effect on MRI's and NMR's business activities.

CERTIFICATE OF NEED REQUIREMENTS

     Certain states have enacted certificate of need ("CON") laws to facilitate
healthcare planning by placing limitations on the purchase of major medical
equipment and other capital expenditures. CON legislation has been enacted in
the states of New Jersey, Pennsylvania, Florida and Illinois, where MRI and NMR
have imaging centers, as well as a number of other states where MRI and NMR do
not currently have imaging centers. These statutes, together with their
implementing regulations, could limit MRI's and NMR's ability to acquire new
imaging equipment or expand or replace its existing equipment, and no assurances
can be given that the required regulatory approvals for any future acquisitions,
expansions or replacements will be granted to MRI or NMR. With respect to MRI's
and NMR's operations in Florida, magnetic resonance imaging equipment and the
free standing centers from which they are operated are presently exempt from CON
review in the State of Florida. The exemption in Florida is based upon prior
Federal Food and Drug Administration approval of the technology for human use.

REIMBURSEMENT UNDER FEDERAL PROGRAMS

     The services offered at MRI's and NMR's imaging centers are made available
to private pay patients (including those covered by a health benefit plan of a
third-party payer) and patients relying on Medicare and/or Medicaid for payment
of their expenses. Medicaid is a program administered by the various states to
provide medical assistance to the indigent. For example, Florida's Department of
Health and Rehabilitative Services promulgates and administers rules affecting
services to Florida Medicaid patients. Medicare, on the other hand, is a
Federally-funded program pursuant to the Federal Health Insurance For the Aged
and Disabled Act. To receive reimbursement under the Medicare and/or Medicaid
programs, MRI, NMR, and/or the physicians rendering services at their imaging
centers, must be certified as a provider of Medicare and/or Medicaid services.
The qualifications for participation in these programs, as well as the programs'
coverage requirements for reimbursement of imaging services, depend upon a
number of factors, and no assurances can be made that MRI and NMR may not be
required to change or improve their facilities, personnel, relationships with
personnel, equipment or services to maintain their Medicare/Medicaid
certification.

STARK LAW

     As part of the Federal Omnibus Budget Reconciliation Act of 1993, Congress
established a ban on physician referrals of Medicare and Medicaid patients to
"designated health services" in which a physician or member of a physician's
immediate family has a "financial interest." A "financial interest" includes
both an ownership or investment interest, including a limited partnership
interest, in the entity furnishing designated health services, and a
compensation arrangement between the physician (or immediate family member) and
the entity furnishing designated health services.

     This law, generally referred to as "Stark II," applies to referrals made on
or after January 1, 1995 to entities furnishing designated health services.
Specifically with regard to MRI's and NMR's operations, the "designated health
services" covered by Stark II's physician self-referral prohibition include
"radiology or other diagnostic services, including magnetic resonance imaging,
computerized axial tomography scans and ultrasound services."

     Stark II provides exceptions, including employment and certain contractual
relationships, but unless an exception to the self-referral restrictions
applies, physicians will be precluded from billing for referred services
rendered to Medicare and Medicaid patients. Violations of Stark II prohibitions
include denial of payment for

                                       62

<PAGE>


designated health services, refunds of amounts billed and collected for such
services, civil monetary penalties and exclusion from the Medicare and Medicaid
programs.

     Stark II also requires MRI and NMR, as providers of diagnostic services, to
report to the Department of Health and Human Services ("HHS") the names and
identification number of physicians who have, or whose immediate family members
have, an investment interest in MRI or NMR, as the case may be.

     In response to the enactment of Stark II, NMR purchased limited partnership
interests from physician and non-physician investors in certain of its limited
partnerships during the fourth quarter of fiscal 1994, and any physician
investors who chose not to divest their interests in NMR's imaging centers are
not permitted to make Medicare or Medicaid referrals to NMR imaging centers.
Prior to the acquisitions of these limited partnership interests, NMR's imaging
centers did not receive a material amount of Medicare or Medicaid referrals from
those physician limited partners who chose not to divest their interests.
Accordingly, any loss of referrals from non-exempt physician limited partners
who chose not to divest their interests in NMR's imaging centers prior to
January 1, 1995 is not expected to have a material adverse impact on NMR's
revenues, net, results of operations and liquidity.

     Although MRI and NMR believe that they are in material compliance with all
applicable Federal laws and regulations which place limitations on referrals of
patients, there can be no assurance that such laws or regulations will not be
amended, interpreted or applied in the future in such a way as to have a
material adverse impact on MRI and/or NMR, or that the Federal government will
not impose additional restrictions upon all or a portion of MRI's and/or NMR's
activities, which might adversely affect MRI's and/or NMR's businesses.

FEDERAL FRAUD AND ABUSE LAW

     MRI and NMR are subject to Federal fraud and abuse laws. The principal
Federal fraud and abuse law contains the illegal remuneration provisions which
prohibit the offering or payment, or the solicitation or acceptance of any
bribe, kickback, rebate or any direct or indirect remuneration, in exchange for
the referral of a patient for items or services reimbursed by the Medicare or
Medicaid programs (the "Anti-Kickback Statute"). The Anti-Kickback Statute is
intended, in part, to prevent the improper referral of patients for medical
tests or treatment by healthcare providers who may have a financial interest in
the entity which provides such services. Among other situations to which this
legislation may be applicable, governmental authorities have from time to time
maintained under certain circumstances that where physicians or other healthcare
providers have made investments in medical care enterprises, although no express
agreement regarding referrals of patients to the enterprise may exist, payments
to the physicians or healthcare providers who refer patients to the enterprise
may violate the Anti-Kickback Statute. Violation of this law may result in
significant criminal and civil penalties and exclusion from participation in the
Medicare and Medicaid programs.

     On July 29, 1991, HHS issued "safe harbor" regulations under the
Anti-Kickback Statute, which define safe payment practices which are not subject
to criminal or civil prosecution. Additional safe harbors were proposed in
September of 1993, but they have not yet been adopted. A safe harbor for
investment interests sets forth eight conditions, which if all are met, assure a
partnership that distributions of profits to its partners who refer patients to
or provide services for the partnership will be deemed not to violate the
Anti-Kickback Statute.

     The safe harbor regulations are not the sole determinant of whether a
healthcare business is operating in compliance with the Anti-Kickback Statute,
and failure to comply with applicable safe harbors does not necessarily make a
particular payment practice illegal. If a payment practice does not fall within
the applicable safe harbors, the arrangement must be examined in light of the
language and intent of the Anti-Kickback Statute. Thus, a healthcare business
can fail to meet the safe harbors and still be operating lawfully under the
Anti-Kickback Statute. Although MRI and NMR believe that they are in general and
substantial compliance with the Anti-Kickback Statute, there can be no assurance
that the HHS' Office of Inspector General, which is responsible for enforcing
the Anti-Kickback Statute, will not challenge MRI's or NMR's position on
compliance with such statute or that, if such a challenge occurred, a court
would uphold MRI's or NMR's position.

STATE REFERRAL LAWS

     Many states, including those states in which MRI and NMR conduct their
businesses, have their own laws which impose restrictions on physicians and
other healthcare providers in connection with the referral of patients to
facilities in which such physicians and providers have an ownership interest.
Unlike the Anti-Kickback Statute, these state referral laws are not limited to
items and services reimbursed by Medicare and Medicaid.

     Although MRI and NMR believe that they are in material compliance with all
applicable state laws and regulations which place limitations on referrals of
patients, there can be no assurance that such laws or regulations

                                       63

<PAGE>


will not be amended, interpreted or applied in the future in such a way as to
have a material adverse impact on MRI and/or NMR, or that state governments will
not impose additional restrictions upon all or a portion of MRI's and/or NMR's
activities, which might adversely affect MRI's and NMR's businesses.

PRACTICE OF MEDICINE

     MRI's and NMR's imaging centers are subject to state laws prohibiting the
practice of medicine by non-physicians and the rebate or division of fees
between physicians and non-physicians. Professional radiology services are
performed at MRI's and NMR's respective imaging centers by licensed physicians
under contract with a medical professional corporation, while MRI and NMR
provide the imaging equipment and technical employees. The physicians with whom
MRI and NMR enter into agreements are subject to requirements of the licensing
authorities of the states in which they practice medicine to assure that such
persons meet the requirements necessary to practice medicine and for the
protection of the public. In addition, the respective imaging centers of MRI and
NMR may be subject to certain states' healthcare facility licensure
requirements. There can be no assurance that state authorities or others may not
challenge this structure as involving MRI or NMR, as the case may be, in the
unlawful practice of medicine or that any required facility licensure approvals
will be granted to MRI or NMR.

     Florida's Department of Health and Rehabilitative Services is required by
law to license MRI's and NMR's imaging centers and to collect certain financial
and operating information from MRI and NMR. Florida law also subjects the
medical personnel performing services at each center to licensure and
regulation.

HEALTHCARE COST CONTAINMENT LEGISLATION

     Federal and state agencies have adopted or are considering medical cost
containment legislation which has restricted or may restrict prices charged by
hospitals and other healthcare providers. Such legislation, together with cost
constraints imposed by insurance companies and other third-party payers, has
reduced, and can be expected to continue to reduce, the fees which MRI and NMR
collect for the use of their diagnostic imaging equipment and/or for the
provision of diagnostic imaging services.

     Federal and state cost containment proposals have not been fully formulated
at this time. Thus, MRI and NMR are unable to determine at this time how any
such proposals that are adopted may affect their businesses, but MRI and NMR
expect that these proposals will reduce their average revenue, net realized for
diagnostic imaging procedures.

     MRI and NMR have been pursuing agreements with health maintenance
organizations (HMOs), preferred provider organizations (PPOs), and others to
provide services to these organizations and their members. These organizations
typically negotiate for and receive an allowance deducted from the standard fee
thereby reducing revenues to MRI and NMR on a per procedure basis. MRI and NMR
expect these contracts to become an increasingly significant part of their mix
of business. Significant changes in coverage, possibly combined with a reduction
in payment rates by third-party payers, would have a material adverse effect on
MRI's and NMR's revenues, net income, results of operations and liquidity.

POSSIBLE NATIONAL HEALTHCARE REFORM

     The enactment of national healthcare reform legislation is uncertain.
Although national healthcare reform laws, if enacted, may have the beneficial
effect of increasing the number of persons who will have access to services
provided by MRI and NMR, such reform laws may also reduce the fees that may be
charged for such services. In particular, there is a possibility that a
significant portion of healthcare services will be rendered and administered
through a system which could force price concessions from service providers such
as MRI and NMR. Moreover, national healthcare reform laws could cause greater
analysis of each patient's need for diagnostic testing, with the aim of
eliminating unnecessary tests and reducing the volume and cost of medical care.
Depending on the nature and extent of any new Federal laws and/or regulations,
or possible changes in the interpretation of existing laws and/or regulations,
the foregoing may have a material adverse effect on MRI's and NMR's revenues,
operating marginsand profitability.

FDA REGULATION

     The use of diagnostic imaging systems are subject to regulation by the Food
and Drug Administration ("FDA") as a medical device. The FDA has approved all of
the devices used by MRI and NMR in substantially all currently utilized
procedures. Although considered by MRI and NMR to be unlikely, there can be no
assurance that the FDA may not promulgate regulations in the future that may
negatively affect their use of diagnostic imaging systems.

          MRI AND NMR UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

     Following is an unaudited pro forma combined balance sheet of MRI (the
"Unaudited Pro Forma Balance Sheet") as of March 31, 1996, an unaudited pro
forma combined statement of income for the fiscal year ended December 31, 1995
(the "Unaudited Pro Forma Statement of Income") and an unaudited pro forma
combined statement of income for the three months ended March 31, 1996 (the
"Unaudited Pro Forma Statement of Income for the Three Months Ended March 31,
1996"). These unaudited pro forma combined financial statements include
historical amounts for MRI and NMR adjusted to reflect the Merger and historical
acquisitions. MRI's historical acquisitions during the year ended December 31,
1995 included New England MRI, Inc. and PCC Imaging, Inc., which were effective
on May 26, 1995 and June 19, 1995, respectively. NMR's historical acquisitions
during its fiscal year ended March 31, 1996 included Morgan Medical Holdings,
Inc. and Central Diversey MRI Center, Inc., which were effective on September
15, 1995 and January 1, 1996, respectively. MRI's historical acquisitions for
which pro forma adjustments have been made for the three months ended March 31,
1996 included MRI-CT, Inc. on January 9, 1996, Nurse Care Plus, Inc. on January
12, 1996, Americare Imaging Centers, Inc. and MRI Associates of Tarpon Springs,
Inc. on April 19, 1996 and Access Imaging Center, Inc. on April 30, 1996. For
purposes of presenting the Unaudited Pro Forma Balance Sheet, the Merger is
considered to have occurred on March 31, 1996. MRI's fiscal year end is December
31 and NMR's fiscal year end is March 31. Accordingly, the Unaudited Pro Forma
Statement of Income has been presented as if the Merger and the historical
acquisitions of MRI had occurred on January 1, 1995 and as if the Merger and the
historical acquisitions of NMR had occurred on April 1, 1995. The Unaudited Pro
Forma Income Statement for the Three Months Ended March 31, 1996 has been
prepared on the basis that the Merger and the historical acquisitions of MRI
occurred as of January 1, 1996. The Merger will be accounted for under the
purchase method of accounting and, therefore, these statements are prepared on
such a basis.

     These unaudited pro forma combined financial statements do not purport to
be indicative of the actual financial position or results of operations that
would have been achieved had the transaction been consummated on such date, or
at the beginning of the periods, for which the pro forma unaudited combined
financial statements are presented, nor do they purport to be indicative of
future operating results or financial position.

     The following unaudited pro forma combined financial statements should be
read in conjunction with the historical consolidated financial statements and
related notes thereto of MRI and NMR, incorporated by reference herein, as
certain data and notes normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted.

          NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

   The Historical Financial Statements

    The Merger--

     The unaudited pro forma combined financial statements are presented for
illustrative purposes only, giving effect to the Merger and historical
acquisitions of MRI and NMR, and therefore, are not necessarily indicative of
the financial position or financial results that might have been achieved had
the Merger occurred as of an earlier date, nor are they necessarily indicative
of the financial position or financial results which may occur in the future.
The Unaudited Pro Forma Balance Sheet has been presented assuming the Merger
occurred on March 31, 1996. MRI's fiscal year end is December 31 and NMR's
fiscal year end is March 31. Accordingly, the Unaudited Pro Forma Statement of
Income has been presented as if the Merger and historical acquisitions of MRI
had occurred on January 1, 1995 and as if the Merger and the historical
acquisitions of NMR had occurred on April 1, 1995. The Unaudited Pro Forma
Income Statement for the Three Months Ended March 31, 1996, has been prepared on
the basis that the Merger and the historical acquisitions of MRI occurred as of
January 1, 1996. The Merger will be accounted for under the purchase method of
accounting, whereby the respective assets and liabilities of NMR are recorded at
their estimated fair values. The total purchase cost of the transaction is
estimated to be approximately $38,952,000 and the excess of the purchase cost
over the estimated fair value of net assets acquired is estimated to be
approximately $36,353,000.

     The Unaudited Pro Forma Statement of Income for the fiscal year ended
December 31, 1995 reflects the impact of historical acquisitions made by MRI and
NMR. MRI's acquisition of New England MRI, Inc. ("NEM") and PCC Imaging, Inc.
("PCC"), which were effective on May 26, 1995 and June 19, 1995, respectively,
are reflected as if such acquisitions had occurred on January 1, 1995. NMR's
acquisition of Morgan Medical Holdings, Inc. ("Morgan") and Central Diversey MRI
Center, Inc. ("CD MRI"), which were effective on September 15, 1995 and January
1, 1996, respectively, are reflected as if such transactions had occurred on
April 1, 1995. MRI acquisitions and NMR's acquisition of CD MRI did not require
shareholder approval. NMR's acquisition of Morgan was approved by its
shareholders.

     The Unaudited Pro Forma Statement of Income for the Three Months Ended
March 31, 1996 reflects the impact of historical acquisitions made by MRI. MRI's
acquisition of MRI-CT, Inc. ("MRI-CT") on January 9, 1996, NurseCare Plus, Inc.
("NurseCare") on January 12, 1996, Americare Imaging Centers, Inc. and MRI
Associates of Tarpon Springs, Inc. (collectively known as "Americare") on April
19, 1996 and Access Imaging Center, Inc. ("Access") on April 30, 1996, are
reflected as if these transactions had occurred on January 1, 1996. These
acquisitions did not require shareholder approval.

2. REVENUE RECOGNITION

     For MRI centers and those centers that NMR acquired (as opposed to
developed, see next paragraph), revenues are recognized on an accrual basis as
earned and consist of patient service revenues adjusted for contractual
adjustments (net patient service revenue) allocated to MRI and NMR under the
terms of management agreements maintained. This revenue is derived from charges
for patient services rendered in diagnostic imaging centers under the terms of
certain payment arrangements with various third party payors, such charges are
paid at amounts less than the Company's established rates.

     For the centers which NMR has developed, agreements have been entered into
with physicians engaging in business as professional associations ("Physicians")
pursuant to which NMR maintains and operates imaging systems in offices operated
by Physicians. The agreements have terms of up to six years and are renewable at
NMR's option. Under the agreements, Physicians have agreed to be obligated to
contract for radiological services at the centers and to sublease each facility.
NMR is obligated to make necessary leasehold improvements, provide furniture and
fixtures and perform certain administrative functions relating to the provisions
of technical aspects of the centers' operations for which Physicians pay a
quarterly fee composed of a fixed sum based on the cost of the respective
imaging system installed, including the related financing costs, a charge per
invoice processed and a charge based upon system usage for each NMR-installed
imaging system in operation. These fees, net of a contractual allowance based
upon Physicians ability to pay after Physicians have fulfilled their obligations
under facility subleases and radiological service contracts as set forth above,
constitute NMR's net revenue for sites developed by NMR.

     MRI also recognizes revenue from temporary nurse staffing.

3. EARNINGS PER SHARE

     MRI and NMR Unaudited Pro Forma Combined earnings per share has been
calculated by dividing net income by the weighted average shares outstanding
during the period, including the weighted average effect of the estimated
4,308,859 shares of MRI Common Stock to be issued in the Merger. MRI, NMR
Combined and MRI, NMR Historical Acquisitions Unaudited Pro Forma earnings per
share has been calculated assuming an additional 600,000 shares issued and
600,000 shares of MRI Common Stock to be issued by MRI in conjunction with the
acquisition of NEM were issued on January 1, 1995 and an additional 1,195,848
and 10,000 shares of NMR Common Stock issued by NMR for the acquisitions of
Morgan and CD MRI, respectively, had occurred on April 1, 1995. The
potentialdilutive effect of warrants to be issued upon consummation of the
Merger and the conversion of all NMR optionsand warrants into MRI options and
warrants was taken into consideration in the pro forma earnings pershare
calculations.

     (1)  To adjust NMR's deferred tax liability related to fixed assets for the
          tax effect impact, using 40%, of pro forma adjustment (C) to adjust
          NMR's fixed assets by $200,000.

     (2)  To adjust NMR's deferred tax liability related to an intangible asset
          for tax effect impact, using 40%, of pro forma adjustment (G) to
          adjust the book value of an NMR intangible asset.

     For purposes of pro forma presentation, as of March 31, 1996, the tax
     effect of the combined Companies' future deductible amounts exceeds future
     taxable amounts, as defined under Statement of Financial Accounting
     Standard No. 109 "Accounting for Income Taxes", by approximately $2,636,000
     and is reflected in the unaudited pro forma balance sheet as of March 31,
     1996 as a component of other assets.

     As discussed in Note 10 to NMR's 1996 Consolidated Financial Statements,
     NMR has recorded deferred tax assets of $2,332,000 related to net operating
     loss carryforwards of $6,389,000. Utilization of certain of these net
     operating loss carryforwards is limited to $520,000 (pre tax effect) per
     year and could be limited further if there are future changes in the
     ownership of NMR. The Merger may result in further limitations on the
     utilization of certain of these net operatingloss carryforwards. No
     adjustment for additional limitations has been made in these pro forma
     combined financial statements because the amounts are not yet known.

     (1)  Represents liabilities assumed as of the consummation date in
          conjunction with the closing of the Elgin and Bel Air centers. The
          components of the costs are: $1,200,000 for the remaining rental

                 AMENDMENT OF MRI'S CERTIFICATE OF INCORPORATION
                    (ITEM NO. 2) (FOR MRI STOCKHOLDERS ONLY)

     At the MRI Meeting, MRI stockholders will be asked to vote on a proposal,
which would only become effective if the Merger is consummated, to amend MRI's
Certificate of Incorporation in order the increase the number of authorized
shares of MRI Common Stock from 20,000,000 shares to 50,000,000. IF THE MERGER
IS NOT CONSUMMATED, THE VOTE ON THIS PROPOSAL WILL BE CONSIDERED VOID AND OF NO
FORCE AND EFFECT.

     By resolution adopted on June 19, 1996, the Board of Directors of MRI
proposed the adoption by MRI stockholders of an amendment to MRI's Certificate
of Incorporation pursuant to which the number of authorized shares of MRI Common
Stock would be increased from 20,000,000 shares to 50,000,000 shares, and the
MRI Board directed that the proposed amendment be submitted to a vote of the
stockholders at the MRI Meeting. If the proposed amendment is approved and upon
its filing with the Secretary of State of the State of Delaware, the newly
authorized shares of MRI Common Stock will have voting and other rights
identical to the currently authorized shares of MRI Common Stock. The proposed
Amendment to MRI's Certificate of Incorporation is attached hereto as Appendix
D.

     Of the 20,000,000 currently authorized shares of MRI Common Stock, as of
July 29, 1996, 8,866,489 shares were issued and outstanding and an additional
2,819,625 shares were reserved for issuances in connection with outstanding MRI
Derivative Securities. MRI's Board of Directors has also reserved for issuance
an additional 114,459 shares upon the exercise of options which may be granted
under MRI's existing option plans. In connection with the Merger, approximately
4,338,517 shares of MRI Common Stock will be issued (assuming no exercise or
conversion of outstanding NMR Derivative Securities) and an additional 1,305,156
shares of MRI Common Stock will be issuable upon exercise or conversion of NMR
Derivative Securities following the Merger. Although presently authorized shares
are sufficient to meet all present requirements of MRI, including shares of MRI
Common Stock to be issued in the Merger, MRI's Board of Directors believes that
it is desirable that MRI have the flexibility to issue a substantial number of
share of MRI Common Stock without further stockholder action unless required by
applicable law or regulation. The availability of additional shares will enhance
MRI's flexibility in connection with possible future actions, such as
acquisitions, stock dividends, stock splits and employee benefit programs. The
MRI Board will determine whether, when and on what terms the issuance of shares
of MRI Common Stock may be warranted in connection with any of the foregoing
purposes.

     The MRI Board of Directors does not intend to seek further stockholder
approval prior to the issuance of any additional shares in future transaction
unless required by law, the Certificate of Incorporation or the rules of any
stock exchange upon which the stock may be listed or quoted, or unless MRI deems
its advisable to do so. Further, the MRI Board does not intend to issue any MRI
Common Stock to be authorized under the proposed amendment to the Certificate of
Incorporation except upon the terms the MRI Board deems to be in the best
interests of MRI and its stockholders. The issuance of additional MRI Common
Stock without further stockholder approval may, among other things, have a
dilutive effect on earnings per share and on the equity of the present holders
of MRI Common Stock and their voting rights, Holders of MRI Common Stock have no
preemptive rights. The availability for issuance of additional shares of MRI
Common Stock also could have the effect of rendering more difficult or
discouraging an attempt to obtain control of MRI.

     The proposed amendment to MRI's Certificate of Incorporation is subject to
approval by the affirmative vote of the holders of a majority of the outstanding
shares of MRI Common Stock.

     It is the intention of the persons named in the accompanying proxy to vote
FOR the election of the proposed amendment to MRI's Certificate of
Incorporation, unless contrary instructions are given or authority to do so is
withheld.

     AT THE MRI MEETING, THE STOCKHOLDERS OF MRI WILL BE REQUESTED TO APPROVE
THE AMENDMENT TO MRI'S CERTIFICATE OF INCORPORATION. THE PROPOSED AMENDMENT TO
MRI'S CERTIFICATE OF INCORPORATION UNDER THIS PROPOSAL WILL ONLY BE GIVEN EFFECT
IF THE MERGER IS CONSUMMATED.

                           (FOR NMR STOCKHOLDERS ONLY)

     At the NMR Meeting, NMR stockholders will be asked to vote on a proposal,
which would only become effective if the Merger is not consummated, to elect
five (5) directors to hold office until the next annual meeting of stockholders
and until their successors have been duly elected and qualified. IF THE MERGER
IS CONSUMMATED, THE VOTE ON THIS PROPOSAL WILL BE CONSIDERED VOID AND OF NO
FORCE AND EFFECT.

     The following five individuals have been nominated for election as
directors in the event the Merger is not consummated: Joseph G. Dasti, Donald W.
Arthur, David L. Bloom, John A. Faraone and Joseph T. Zappala. Each of the
nominees is currently a director of NMR. For biographical and other information

     The directors of NMR will be elected by a plurality of the votes cast by
stockholders of NMR present at the NMR Meeting in person or represented by proxy
if a quorum is present.

     It is the intention of the persons named in the accompanying proxy to vote
FOR the election of the five nominees, unless contrary instructions are given or
authority to do so is withheld.

     AT THE NMR MEETING, THE STOCKHOLDERS OF NMR WILL BE REQUESTED TO ELECT FIVE
DIRECTORS TO THE BOARD OF DIRECTORS. THE DIRECTORS OF NMR WILL BE ELECTED BY A
PLURALITY OF THE VOTES CAST BY STOCKHOLDERS OF NMR PRESENT AT THE NMR MEETING IN
PERSON OR REPRESENTED BY PROXY. THE ELECTION OF ANY DIRECTORS UNDER THIS
PROPOSAL WILL ONLY BE GIVEN EFFECT IF THE MERGER IS NOT CONSUMMATED.

                                  OTHER MATTERS

     As of the date of this Joint Proxy Statement/Prospectus, the Board of
Directors of MRI knows of no other business to be presented at the MRI Meeting
and the Board of Directors of NMR knows of no other business to be presented at
the NMR Meeting. However, if any other matters properly come before either such
meeting, the persons named in the enclosed form of proxy are expected to vote
the proxy in accordance with their best judgment onsuch matters.

     AGREEMENT AND PLAN OF MERGER dated as of May 20, 1996 (the "Agreement"), by
and among MEDICAL RESOURCES, INC., a Delaware corporation ("MRI"), MRI SUB,
INC., a Delaware corporation and wholly-owned subsidiary of MRI ("Sub"), and NMR
OF AMERICA, INC., a Delaware corporation ("NMR") (Sub and NMR being hereinafter
collectively referred to as the "Constituent Corporations").

     WHEREAS, the respective Boards of Directors of MRI, Sub, and NMR have each
determined that it is advisable and for the benefit and in the best interests of
their corporations and their respective stockholders that NMR be acquired by MRI
(the "Acquisition") by means of a merger of NMR with and into Sub, with Sub
being the surviving corporation, on the terms and conditions hereinafter set
forth (the "Merger");

     WHEREAS, the Board of Directors of MRI has determined that the Acquisition
is consistent with and in furtherance of the long-term business strategy of MRI
and is fair to, and in the best interests of, MRI and the holders of MRI Common
Stock, as hereinafter defined, and has approved and adopted this Agreement and
has approved the Merger and the other transactions contemplated hereby and
recommended approval and adoption of the Agreement and approval of the Merger by
the stockholders of MRI; and

     WHEREAS, the Board of Directors of NMR has determined that the Acquisition
is fair to, and in the best interests of, NMR and the holders of NMR Common
Stock, as hereinafter defined, and has approved and adopted this Agreement and
has approved the Merger and the other transactions contemplated hereby and
recommended approval and adoption of the Agreement and approval of the Merger by
the stockholders of NMR;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
qualify as a reorganization under the provisions of Section 368(a)(1)(A) and
368(a)(2)(D);

     NOW, THEREFORE, in consideration of the premises, the mutual covenants,
representations and warranties herein contained, and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto intending to be bound hereby agree as follows:

                                    ARTICLE 1

                                   THE MERGER

     SECTION 1.1 THE MERGER. Subject to the terms and conditions hereof, on the
Effective Date (as defined in Section 1.3), NMR shall be merged with and into
Sub in accordance with the applicable provisions of the laws of the State of
Delaware ("Delaware Law"); Sub, as the surviving corporation in the Merger (the
"Surviving Corporation"), shall continue its corporate existence under Delaware
Law; the separate existence of NMR shall thereupon cease; and its corporate
existence shall be merged into and transferred to the Surviving Corporation.

     SECTION 1.2 STOCKHOLDERS' MEETINGS. To the extent consistent with the
fiduciary duty of their respective Boards of Directors, each of NMR and MRI
shall, as soon as practicable, take all action necessary in accordance with
applicable law and its Certificate of Incorporation and By-Laws to convene a
meeting of its stockholders to consider and vote upon the approval of the Merger
(together, the "Stockholders' Meetings") and to solicit proxies with respect to
such meeting. The Boards of Directors of each of NMR and MRI has recommended
that its stockholders approve the Merger.

     SECTION 1.3 CONSUMMATION OF THE MERGER; EFFECTIVE DATE. As soon as
practicable following the Closing (as that term is hereinafter defined in
Section 2.5), the parties hereto will file with the Secretary of State of the
State of Delaware a Certificate of Merger in such form as required by, and
executed in accordance with, the relevant provisions of Delaware Law. The Merger
shall become effective at such time (the "Effective Time") as the Certificate of
Merger shall have been duly filed with the Secretary of State of the State of
Delaware (the "Effective Date").

     SECTION 1.4 EFFECT OF THE MERGER. Upon the effectiveness of the Merger, the
Surviving Corporation shall succeed, without any other action, to all rights and
property of each of the Constituent Corporations, and shall be subject to all
the debts and liabilities of each of the Constituent Corporations in the same
manner as if the Surviving Corporation had itself incurred them, all with the
effect set forth in Delaware law. Without limiting the generality of the
foregoing, following effectiveness of the Merger, the Surviving Corporation
shall assume responsibility, either directly or indirectly, for the
administration of NMR's 401(K) Plan.

                                      A-1

                                    ARTICLE 2

                           CONVERSION AND CANCELLATION
                                  OF SECURITIES

     SECTION 2.1 CONVERSION OF SHARES; TREATMENT OF WARRANTS, OPTIONS AND
CONVERTIBLE SECURITIES. As of the Effective Date, by virtue of the Merger and
without any action on the part of the holders thereof:

          (a) Common Stock. (i) On the Effective Date, the shares of NMR's
     Common Stock, $.01 par value (the "NMR Common Stock"), issued and
     outstanding immediately prior to the Effective Date, other than Dissenting
     Shares (as hereinafter defined) and other than any shares of NMR Common
     Stock held by MRI, Sub or NMR, shall, by virtue of the Merger automatically
     and without any action on the part of the holder thereof, become and be
     converted into the right to receive shares of fully paid and nonassessable
     Common Stock, $.01 par value, of MRI (the "MRI Common Stock"). The shares
     of MRI Common Stock issuable in the Merger are sometimes collectively
     referred to hereinafter as the "Merger Consideration" and the ratio of
     0.6875 shares of MRI Common Stock to one share of NMR Common Stock is
     herein referred to as the "Exchange Ratio."

          (ii) Capital Stock Held by NMR, MRI or Sub. On the Effective Date,
     each share of capital stock of NMR held in the treasury of NMR, or by MRI
     or Sub immediately prior to the Effective Date shall, by virtue of the
     Merger and without any action on the part of the holder thereof, be
     automatically cancelled and retired and cease to exist and no securities or
     other consideration shall be payable in respect thereof.

          (b) Warrants. Each warrant to acquire shares of NMR Common Stock (a
     "Warrant") that is outstanding and unexercised at the Effective Date shall,
     by virtue of the Merger and without any action on the part of the holder
     thereof, and subject to the other terms and conditions thereof,
     automatically be deemed to be exercisable for that number of shares of MRI
     Common Stock the holder of such Warrant would have received in the Merger
     pursuant to Section 2.1(a) had such holder exercised such Warrant in full
     immediately prior to the Effective Date, and the price per share of MRI
     Common Stock issuable after the Effective Date upon exercise of such
     Warrant shall equal the price per share of NMR Common Stock under such
     Warrant as in effect prior to the Effective Date divided by the Exchange
     Ratio. Without limiting the generality of the foregoing, following
     effectiveness of the Merger, MRI shall be bound by and subject to all
     registration rights contained in each Warrant and such rights shall apply
     against MRI with the same legal force and effect as they applied against
     NMR prior to effectiveness of the Merger. After the Effective Date, MRI
     shall issue to each holder of a Warrant a new warrant containing the
     foregoing terms and all other terms set forth in each Warrant, including
     without limitation, all registration rights; provided, however, that the
     failure of MRI to so issue new warrants in substitution of Warrants shall
     not limit the rights of the holder hereunder or thereunder and each such
     Warrant will be deemed amended to substitute MRI in place of NMR and the
     terms and conditions of each such Warrant shall be applicable to MRI in the
     same manner as they would be applicable to NMR if the Merger had not
     occurred.

          (c) Options. At the Effective Date, each stock option ("NMR Option")
     outstanding on the date hereof pursuant to the 1986 Incentive Stock Option
     and Nonstatutory Option Plan ("NMR Plan") shall be deemed to constitute and
     shall automatically be converted into stock options ("New Options")
     exercisable for shares of MRI Common Stock and each NMR Option shall be
     administered in accordance with the terms and conditions provided for in
     the NMR Plan under which the corresponding NMR Option was granted and the
     stock option agreement by which it was evidenced, including terms and
     provisions regarding exercisability. The number of shares of MRI Common
     Stock covered by each New Option shall be the number of shares of MRI
     Common Stock which the holder of the NMR Option would have received in the
     Merger pursuant to Section 2.1(a) had such holder exercised the NMR Option
     in full immediately prior to the Effective Date, without regard to vesting;
     provided, however, that the number of shares of MRI Common Stock that may
     be purchased upon exercise of a New Option shall not include any fractional
     share interest which shall be cashed out upon exercise for an amount of
     cash (without interest) determined by multiplying such fractional share
     interest by the average reported last sale price of MRI Common Stock on the
     NASDAQ system for the five (5) trading days ending on the close of business
     on the last business day immediately preceding the date of such exercise.
     The exercise price per share of MRI Common Stock subject to a New Option
     shall equal the exercise price per share (subject to the adjustments
     provided for in the NMR Option) of NMR Common Stock subject to the
     corresponding NMR Option so converted divided by the Exchange Ratio.
     Without limiting the rights of holders of NMR Options, as soon as
     practicable after the Effective Date, MRI shall issue to the holders of
     such NMR Options appropriate instruments 


                                      A-2
<PAGE>

     evidencing New Options and confirming the rights of such holders with
     respect to MRI Stock on the terms and conditions provided by this Section
     2.1, upon surrender of the outstanding instruments representing such NMR
     Option; provided, however, that MRI shall not be obligated to issue any
     shares of MRI Stock, until such time as the shares of MRI Stock issuable
     upon exercise of New Options shall have been registered with the Securities
     and Exchange Commission (the "SEC") pursuant to an effective registration
     statement and authorized for quotation on the NASDAQ--National Market
     System and for sale by any appropriate state securities regulators, which
     MRI shall use its best efforts to effect as promptly as practicable, but in
     no event more than 15 days after the Effective Date, and MRI shall use its
     best efforts to maintain the effectiveness of such registration statements
     (and maintain the current status of the prospectus or prospectuses
     contained therein) for so long as the NMR Options remain outstanding. At or
     prior to the Effective Date, MRI shall take all corporate action necessary
     to reserve for issuance a sufficient number of shares of MRI Common Stock
     for delivery upon exercise of New Options. Notwithstanding the requirements
     of the NMR Plan, so long as a registration statement covering the MRI
     Common Stock underlying the New Option is effective, if any holder of a New
     Option sells any or all of the shares of MRI Common Stock covered by such
     New Option in a brokers transaction prior to the exercise of such New
     Option ("Short Sale"), MRI shall, upon written notice to MRI of such Short
     Sale by the holder or his or her broker, cause its transfer agent to issue
     in the name of holder and deliver to the holder's broker within three
     business days a certificate evidencing such shares to be applied against
     the Short Sale and upon receipt of payment against delivery of the shares,
     the holder will direct his or her broker to authorize payment directly to
     MRI of the exercise price from the proceeds of such Short Sale.

          (d) Convertible Securities. The obligations of NMR under each 8%
     Convertible Subordinated Debenture due 2001 of NMR (a "Debenture")
     (including, without limitation, the due and punctual payment of the
     principal of (and premium, if any) and interest thereon) that is
     outstanding at the Effective Date shall, by virtue of the Merger and
     without any action on the part of NMR or MRI, be assumed in full by, and
     become the obligations of, the Surviving Corporation which shall comply
     after the Effective Date with all requirements of the Indenture, dated as
     of July 1, 1986 (the "Indenture") pursuant to which the Debentures were
     issued. Each Debenture that is outstanding at the Effective Date shall, by
     virtue of the Merger and without any action on the part of the holder
     thereof, and subject to the other terms and conditions thereof,
     automatically be deemed to be convertible for that number of shares of MRI
     Common Stock that the holder of such Debenture would have received in the
     Merger pursuant to Section 2.1(a) had such holder converted such Debenture
     in full immediately prior to the Effective Date, and the price per share of
     MRI Common Stock issuable after the Effective Date upon conversion of such
     Debenture shall equal the "conversion price" under such Debenture in effect
     prior to the Effective Date divided by the Exchange Ratio. MRI shall, and
     shall cause the Surviving Corporation to, comply with any and all
     requirements of, and execute and deliver any and all agreements required
     by, the Indenture pertaining to a merger or consolidation of NMR.

     SECTION 2.2 APPRAISAL RIGHTS. Holders of shares of NMR Common Stock, who
duly exercise and perfect appraisal rights under Section 262 of the Delaware
General Corporation Law (such shares referred to herein as "Dissenting Shares")
shall have the appraisal rights set forth in Section 262 of the Delaware General
Corporation Law and no other rights; provided, however, that Dissenting Shares
beneficially and legally owned by the holder thereof at the Effective Date who
shall, after the Effective Date, withdraw the demand for appraisal or lose the
right of appraisal as provided in such law, shall be deemed to be converted as
of the Effective Date, into the right to receive the Merger Consideration set
forth in Section 2.1 hereof.

     SECTION 2.3 SURRENDER AND PAYMENT. After the Effective Date, each holder of
a certificate that formerly represented shares of NMR Common Stock, issued and
outstanding on the Effective Date (other than any Dissenting Shares and shares
held by NMR, MRI or Sub) shall be entitled, upon surrender thereof to the
Surviving Corporation, to receive the Merger Consideration for each share of MRI
Common Stock theretofore represented by the certificate so surrendered as
provided in Section 2.1 hereof, and the certificate so surrendered shall
forthwith be cancelled.

     SECTION 2.4 COMMON STOCK OF SUB. Each share of common stock, par value $.01
per share, of Sub issued and outstanding on the Effective Date shall, by virtue
of the Merger and without any action on the part of the holder thereof, remain
outstanding and shall thereafter represent one share of common stock of the
Surviving Corporation.

     SECTION 2.5 CLOSING. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place, unless the parties shall otherwise
agree, at the offices of Werbel McMillin & Carnelutti, 711 Fifth Avenue, New
York, New York 10022 at 10:00 A.M. local time (i) as soon as practicable after
the day on which the last

                                      A-3

<PAGE>

condition set forth in Article 9 shall have been fulfilled or waived or (ii) at
such other time as NMR and MRI may mutually agree (the "Closing Date").

                                    ARTICLE 3

                    CERTIFICATES OF INCORPORATION AND BY-LAWS

     SECTION 3.1 CERTIFICATE OF INCORPORATION AND BY-LAWS. As of the Effective
Date, the Certificate of Incorporation and By-laws of Sub as in effect on the
Effective Date shall be the Certificate of Incorporation and By-Laws of the
Surviving Corporation until thereafter amended as provided by law.

     SECTION 3.2 DIRECTORS AND OFFICERS OF SUB. The directors and officers of
Sub at the Effective Time shall be the initial directors and officers of the
Surviving Corporation and shall hold office from the Effective Time until the
respective successors are duly elected or appointed and qualified in the manner
provided in the Certificate of Incorporation or By-Laws of the Surviving
Corporation or as otherwise provided by law.

                                    ARTICLE 4

                      CERTAIN PROVISIONS RELATING TO SHARES

     SECTION 4.1 NO FRACTIONAL SHARES OF MRI COMMON STOCK. No fractional shares
of MRI Common Stock shall be issued by MRI in the Merger. Each stockholder of
NMR who otherwise would be entitled to a fractional interest in any share of MRI
Common Stock shall receive an amount of cash (without interest) determined by
multiplying the average reported last sale price of MRI Common Stock on the
NASDAQ system for the five (5) trading days ending on the close of business on
the second (2) business day before the Stockholders' Meeting of NMR (the "Fair
Market Value") by the fractional share interest to which such holder would
otherwise be entitled. Unless and until the certificate which immediately prior
to the Effective Date represented shares of NMR Common Stock (the
"Certificates") shall have been surrendered, the holder of any Certificate
representing a fraction of a share of MRI Common Stock shall not be entitled to
receive the cash payment described in this Section 4.1 for such fraction of a
share. Such payment shall be remitted, without interest, after the surrender of
the Certificates held by such holder as provided in Section 4.2.

     SECTION 4.2 MRI TO MAKE MERGER CONSIDERATION AVAILABLE. MRI shall designate
its stock transfer agent to act as exchange agent (the "Exchange Agent") in
connection with the Merger. As soon as practicable after the Effective Date, MRI
shall make available and, subject to Section 4.1, each holder of a Certificate
shall be entitled to receive, upon surrender to the Exchange Agent of such
Certificate for cancellation and subject to any required withholding of taxes
under any applicable federal income tax laws ("Backup Withholding"), the
aggregate number of shares of MRI Common Stock into which the shares of NMR
Common Stock, previously represented by each Certificate shall have been
converted in the Merger. Until so surrendered and exchanged, each Certificate
(other than Certificates representing any Dissenting Shares or shares of the
capital stock of NMR held by NMR, MRI or Sub) shall represent solely the right
to receive the Merger Consideration into which the shares of NMR Common Stock it
represented prior to the Effective Date shall have been converted pursuant to
Section 2.1, less any Backup Withholding. As soon as practicable after the
Effective Date, MRI shall cause the Exchange Agent to mail a transmittal form to
each holder of a Certificate advising such holder of the procedure for
surrendering to the Exchange Agent such Certificates for payment in accordance
with this Section 4.2.

     SECTION 4.3 DIVIDENDS; TRANSFER TAXES; VOTING RIGHTS. (a) No dividends or
distributions that are otherwise payable on MRI Common Stock will be paid to
persons entitled to receive MRI Common Stock until such persons surrender their
Certificates. Upon such surrender, there shall be paid to the person in whose
name MRI Common Stock shall be issued, any dividends or distributions which
shall have become payable with respect to MRI Common Stock between the Effective
Date and the time of such surrender. After such surrender, there shall be paid
to the person in whose name the MRI Common Stock shall be issued any dividends
or distributions on MRI Common Stock which shall have a record date prior to
such surrender and a payment date after such surrender, and such payment shall
be made on such payment date.

     (b) If shares of MRI Common Stock are to be issued or delivered to any
person other than the person in whose name the Certificate surrendered for
exchange is registered, it shall be a condition of the exchange that the person

                                      A-4

<PAGE>

requesting such exchange shall deliver to the Exchange Agent all documents
required to evidence and effect such transfer, and pay to the Exchange Agent any
transfer or other taxes required by reason of the issuance or delivery of a
certificate representing such shares of MRI Common Stock to other than the
registered owner of the Certificate surrendered, or shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.

     SECTION 4.4 ABANDONED PROPERTY; LOST CERTIFICATES. Notwithstanding anything
to the contrary contained herein, neither the Exchange Agent nor any party
hereto shall have any liability to a holder of a Certificate for the payment of
the Merger Consideration to be issued in accordance with the provisions hereof
if such Merger Consideration is paid to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any Certificates shall
not have been surrendered prior to three (3) years after the Effective Date (or
immediately prior to such earlier date on which any payment in respect thereof
would otherwise escheat to or become the property of any governmental unit or
agency), the payment in respect of such Certificates shall, to the extent
permitted by applicable law, become the property of the Surviving Corporation,
free and clear of all claims of interest of any person previously entitled
thereto. Lost Certificates shall be treated in accordance with the normal
procedures of the Exchange Agent.

     SECTION 4.5 TAKING OF NECESSARY ACTION; FURTHER ACTION. Sub, MRI and NMR
shall each take all such action as may be necessary or appropriate in order to
effectuate the Merger as promptly as possible, subject to all of the terms and
conditions hereof. If, at any time after the Effective Date, any further action
is necessary or desirable to carry out the purposes of this Agreement and to
vest the Surviving Corporation with full right, title and possession to all
assets, property, rights, privileges, powers and franchises of either of the
Constituent Corporations, the officers and directors of such corporation are
fully authorized in the name of such corporation or otherwise to take, and shall
take, all such action.

     SECTION 4.6 CLOSING OF NMR'S TRANSFER BOOKS. On the Effective Date, the
stock transfer books of NMR shall be closed and no transfer of shares of capital
stock of NMR shall thereafter be made, except for transfers of Dissenting
Shares, as permitted by law. If, after the Effective Date, certificates
representing shares of NMR Common Stock are presented to the Surviving
Corporation, they shall, subject to the provisions of Section 4.4 hereof, be
cancelled and exchanged for the Merger Consideration provided in Section 2.1
hereof.

                                    ARTICLE 5

                      REPRESENTATIONS AND WARRANTIES OF NMR

     Except as set forth in the Disclosure Schedule to be delivered by NMR to
MRI (the "NMR Disclosure Schedule"), which shall identify exceptions by specific
Section references, NMR hereby represents and warrants to MRI that:

     SECTION 5.1 ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. Each of NMR and
its subsidiaries is a corporation or limited partnership, as the case may be,
duly incorporated (if a corporation), duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
organization, has all requisite power and authority to own, lease and operate
its properties and to carry on its business as it is now being conducted and is
duly qualified and in good standing to do business in each jurisdiction in which
the nature of the business conducted by it or the ownership or leasing of its
properties makes such qualification necessary, other than where the failure to
be in good standing, or to have such power and authority, or to be duly
qualified and in good standing, as the case may be, would not have a NMR
Material Adverse Effect. The term "NMR Material Adverse Effect" as used in this
Agreement shall mean any event, change or effect that, individually or when
taken together with all other such events, changes or effects, would be
materially adverse to the condition (financial or otherwise), prospects,
properties, assets, business or operations of NMR and its subsidiaries, taken as
a whole, at the time of such event, change or effect; provided, however, that
for purposes of this Agreement, any change occurring between the date of this
Agreement and the Effective Date in the amount of cash held by NMR as a direct
result of payment of expenses relating to the Merger (including the payments to
Joseph G. Dasti and John P. O'Malley referred to in Section 7.7) shall not be
deemed an NMR Material Adverse Effect.

     SECTION 5.2 CERTIFICATES OF INCORPORATION AND BY-LAWS. NMR has heretofore
furnished to MRI complete and correct copies of the Certificates of
Incorporation and the By-Laws or the equivalent organizational

                                      A-5
<PAGE>

documents, in each case as amended or restated, of NMR and each subsidiary.
Neither NMR nor any subsidiary is in violation of any of the provisions of its
Certificate of Incorporation or By-Laws or certificate of limited partnership,
or equivalent organizational document, as the case may be.

     SECTION 5.3 CAPITALIZATION. As of the date of this Agreement, the
authorized capital stock of NMR consists of (i) 30,000,000 shares of NMR Common
Stock, of which: (v) 6,273,683 shares of NMR Common Stock are issued and
outstanding, all of which are duly authorized, validly issued, fully paid and
nonassessable and not subject to preemptive rights created by statute, common
law, NMR's Certificate of Incorporation or By-Laws or, any agreement to which
NMR is a party or is bound or otherwise; (w) 430,797 shares of NMR Common Stock
are held in the treasury of NMR; (x) 454,222 shares of NMR Common Stock are
reserved for future issuance in connection with NMR's outstanding Convertible
Subordinated Debentures (the "Debt Securities"); (y) 1,480,409 shares of NMR
Common Stock are reserved for future issuance pursuant to (1) outstanding
employee stock options (collectively the "NMR Employee Stock Options") granted
pursuant to the 1986 Incentive Stock Option and Non-Statutory Option Plan, as
amended, (the "Employee Option Plan"), and (2) outstanding stock purchase
warrants or other rights to purchase NMR Common Stock (the "NMR Warrants" and,
together with NMR Employee Stock Options, collectively the "Stock Options"); and
(z) 57,337 shares of NMR Common Stock issued to the trustee of NMR's 401(K) Plan
and (ii) 500,000 shares of preferred stock, par value $.05 per share ("NMR
Preferred Stock"), of NMR, of which no shares are issued or outstanding. Each of
the outstanding shares of capital stock of, or other equity interests in, each
of NMR's subsidiaries is duly authorized and validly issued and, if applicable,
fully paid and nonassessable, and such shares or other equity interests owned by
NMR or any subsidiary of NMR are owned free and clear of all security interests,
liens, claims, pledges, agreements, limitations on NMR's or any subsidiary's
voting rights, charges or other encumbrances of any nature whatsoever. As of the
date of this Agreement, there are no options, warrants or other rights
(including registration rights), agreements, arrangements or commitments of any
character to which NMR or any of its subsidiaries is a party relating to the
issued or unissued capital stock or other securities of NMR or any of its
subsidiaries or obligating NMR or any of its subsidiaries to grant, issue or
sell any shares of the capital stock or other securities of NMR or any of its
subsidiaries, by sale, lease, license or otherwise, except (A) as disclosed in
Section 5.3 of the NMR Disclosure Schedule and (B) for NMR's existing stock
option plans to the extent stock options for such shares thereunder have not yet
been granted. As of the date of this Agreement, except as set forth in Section
5.3 of the NMR Disclosure Schedule, there are no obligations, contingent or
otherwise, of NMR or any of its subsidiaries to (x) repurchase, redeem or
otherwise acquire any shares of NMR Common Stock or NMR Preferred Stock, or the
capital stock of, or other equity interests in, any subsidiary of NMR or (y)
(other than advances to subsidiaries in the ordinary course of business) provide
funds to, or make any investment in (in the form of a loan, capital contribution
or otherwise), or provide any guarantee with respect to the obligations of, any

subsidiaries or by which any of their respective properties is bound or subject
to including, without limitation, Section 203 of Delaware Law or (iii) result in
any breach of or constitute a default (or an event that with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance on any of the properties or assets of NMR or
any of its subsidiaries pursuant to, any note, bond, mortgage, indenture,

appropriate to preclude the triggering or applicability of the provisions of
NMR's Stockholders' Rights Agreement to the Merger and transactions contemplated

performance of this Agreement by NMR and the ownership and operation of the
business and properties of NMR and its subsidiaries by the Surviving Corporation
following the Effective Date will not, as of the date of this Agreement, require
NMR or any of its subsidiaries to obtain any consent, approval, authorization or

requirements, if any, of the Securities Act of 1933, as amended (the "Securities
Act"), and the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
state securities or blue sky laws ("Blue Sky Laws") the Hart-Scott-Rodino
Antitrust Improvements Act ("HSR Act"), the New Jersey Industrial Site Recovery
Act ("ISRA"), the NASD, the Philadelphia Stock Exchange and the filing and
recordation of appropriate merger documents as required by Delaware Law and (ii)
where the failure to obtain such consents, approvals, authorizations or permits,
or to make such filings or notifications, would not, either individually or in
the aggregate, prevent NMR from performing its obligations under this Agreement
or otherwise have a NMR Material Adverse Effect.

     SECTION 5.6 PERMITS; COMPLIANCE. Each of NMR and its subsidiaries is in
possession of all franchises, grants, authorizations, licenses, permits,
easements, variances, exemptions, consents, certificates, approvals and orders

as it is now being conducted (collectively, the "NMR Permits"), and there is no
action or proceeding or, to the knowledge of NMR, investigation pending or
threatened regarding suspension or cancellation of any NMR Permits, except where
the failure to possess, or the suspension or cancellation of, such NMR Permits

subsidiaries is in conflict with, or in default or violation of (a) any Law or
any rule of professional conduct applicable thereto and applicable to NMR or any
of its subsidiaries or by which any of their respective properties is bound or
subject to or (b) any of NMR Permits, except for any such conflicts, defaults or

that:

     SECTION 6.1 ORGANIZATION AND QUALIFICATION; SUBSIDIARIES. Each of MRI, Sub

the nature of the business conducted by it or the ownership or leasing of its
properties makes such qualification necessary, other than where the failure to

qualified and in good standing, as the case may be, would not have a MRI
Material Adverse Effect. The term "MRI Material Adverse Effect" as used in this
Agreement shall mean any event, change or effect that, individually or when
taken together with all other such events, changes or effects, would be
materially adverse to the condition (financial or otherwise), prospects,

furnished to NMR complete and correct copies of the Certificates of
Incorporation and the By-Laws or the equivalent organizational documents in each

sell any shares of the capital stock or other securities of MRI or any of its
subsidiaries, by sale, lease, license or otherwise, except (A) as disclosed in

obligations hereunder and to consummate the transactions contemplated hereby
(other than with respect to the Merger, the approval and adoption of this
Agreement by the holders of the MRI Common Stock in accordance with applicable
law or the rules of the NASD). The execution and delivery of this Agreement by
MRI and Sub and the consummation by MRI and Sub of the transactions contemplated
hereby have been duly authorized by all necessary corporate action and no other
corporate proceedings on the part of MRI or Sub are necessary to authorize this

majority of the outstanding shares of MRI Common Stock in accordance with
Delaware Law). This Agreement has been duly executed and delivered by MRI and
Sub and, assuming the due authorization, execution and delivery thereof by NMR,

and delivery of this Agreement by MRI and Sub does not, and the performance of
this Agreement by MRI and Sub and the consummation of the transactions

effect as of the date of this Agreement applicable to MRI or Sub or by which any

amendment, acceleration or cancellation of, or result in the creation of a lien
or encumbrance on the properties or assets of MRI or Sub pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit, order,
decree, franchise or other instrument or obligation to which MRI or Sub is a
party or by which MRI or Sub or any of their respective properties is bound or
subject to, except for any such conflicts or violations described in clause (ii)
or breaches, defaults, events, rights of termination, amendment, acceleration or
cancellation or liens or encumbrances described in clause (iii) that would not
have a MRI Material Adverse Effect. The Board of Directors of MRI has taken all
actions necessary under Delaware Law, including approving the transactions
contemplated in this Agreement, to ensure that Section 203 of Delaware Law does
not, or will not, apply to the transactions contemplated in this Agreement. As
used herein, "MRI Permit" shall mean all franchises, grants, authorizations,
licenses, permits, easements, variances, exemptions, consents, certificates,
approvals and orders necessary for MRI and its subsidiaries to own, lease and
operate its properties and to carry on its business as it is now being

     (b) The execution and delivery of this Agreement by MRI and Sub does not,
and the performance of this Agreement by MRI and Sub will not, as of the date of
this Agreement, require MRI or any subsidiary of MRI to obtain any consent,
approval, authorization or permit of, or to make any filing with or notification
to, any Governmental Entities, except (i) for applicable requirements, if any,
of the Securities Act, the Exchange Act, Blue Sky Laws, HSR Act and ISRA and the
filing and recordation of appropriate merger documents as required by Delaware
Law and (ii) where the failure to obtain such consents, approvals,
authorizations or permits, or to make such filings or notifications, would not,

performing its obligations under this Agreement or otherwise have a MRI Material
Adverse Effect.

     to occur of (A) July 31, 1996 or (B) the date upon which NMR and MRI shall
     have submitted written responses to the SEC's initial comments to the
     Registration Statement (as such term is defined in Section 8.2) (such
     earlier date is herein referred to as the "Transaction Termination Date")
     the Company may enter into definitive agreements relating to Permitted

     such date), acquire or agree to acquire, by merging or consolidating with,
     by purchasing an equity interest in or a portion of the assets of, or by

     subsidiary) thereof, or otherwise acquire or agree to acquire any assets of
     any other person (other than the purchase of assets from suppliers or
     vendors in the ordinary course of business and consistent with past
     practice) in each case which are material, individually or in the
     aggregate, to it and its subsidiaries, taken as a whole;

          (i) other than in connection with Permitted Transactions in which
     definitive agreements are entered into on or prior to the Transaction
     Termination Date (which Permitted Transactions may be consummated after
     such date), sell, lease, exchange, mortgage, pledge, transfer or otherwise
     dispose of, or agree to sell, lease, exchange, mortgage, pledge, transfer
     or otherwise dispose of, any of its assets or any assets of any of its

officers, directors, employees, accountants, consultants, legal counsel, agents
and other representatives (collectively, the "Representatives") access upon
reasonable prior notice to its officers, employees, agents, properties, offices
and other facilities and to the books and records thereof and (ii) furnish
promptly to the other party and its Representatives such information concerning
the business, properties, contracts, records and personnel of it and its
subsidiaries (including, without limitation, financial, operating and other data
and information) as may be requested, from time to time, by the other party. All
of such data and information shall be subject to the terms and conditions of the
confidentiality agreement each signed for the benefit of the other party dated
May 1, 1996 (the "Confidentiality Agreement").

     SECTION 7.5 CONFIDENTIALITY. The parties will comply with all of their
respective obligations under the Confidentiality Agreement.

     SECTION 7.6 NO SOLICITATION OF BUSINESS TRANSACTIONS BY NMR; FEE PAYABLE
FOR VIOLATION. (a) Between the date hereof and the earlier to occur of (i)
termination of this Agreement in the event that this Agreement is terminated
pursuant to Sections 10.1(a), 10.1(b), 10.1(c), 10.1(d) or 10.1(i); (ii) January
31, 1997 in the event that this Agreement is terminated pursuant to Section
10.1(e) and (iii) three months following the date this Agreement terminates, but
no later than January 31, 1997, in the event this Agreement terminates pursuant
to Section 10.1(f), 10.1(g) or 10.1(h) (the "No-Shop Period"), neither NMR nor
MRI (the "Target Company," as the case may be) shall, nor shall it permit any of
its principals, agents or representatives to initiate, solicit or encourage
(including by way of furnishing information or assistance), or take any other
action intended to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Business Transaction
(as hereinafter defined), or enter into discussions or negotiate with any person
or entity in furtherance of such inquiries or to obtain a Business Transaction,
or agree to or endorse any Business Transaction, or authorize or permit any of
its officers, directors or employees or any of its subsidiaries or any
investment banker, financial advisor, attorney, accountant or other
representative retained by its or any of its subsidiaries to take any such
action; provided, however, that nothing contained in this subsection (a) shall
prohibit the Board of Directors of the Target Company from (i) furnishing
information to, or entering into discussions or negotiations with, any persons
or entity in connection with an unsolicited bona fide proposal by such person or
entity to enter into a Business Transaction if, and only to the extent that (A)
the Board of Directors of the Target Company, after consultation with
independent legal counsel

                                      A-16

<PAGE>

(which may include its regularly engaged outside legal counsel), determines in
good faith that such action is required for the Board of Directors of the Target
Company to comply with its fiduciary duties to stockholders imposed by Delaware
Law and (B) prior to furnishing such information to, or entering into
discussions or negotiations with, such person or entity, the Target Company (x)
provides written notice to the other party (the "Other Party") to the effect
that it is furnishing information to, or entering into discussions or
negotiations with, such person or entity and, unless the Target Company receives
the written advice of counsel from the Target Company's independent counsel that
disclosure would violate Delaware law, promptly notify the Other Party of all
relevant terms of any such inquiries and proposals received relating to any of
such matters, and (y) receives from such person or entity an executed
confidentiality agreement on terms no less favorable to NMR or MRI than those
contained in the Confidentiality Agreement between NMR and MRI; or (ii)
complying with Rule 14e-2 promulgated under the Exchange Act with regard to a
Business Transaction. For purposes of this Agreement, "Business Transaction"
shall be defined as any merger, acquisition, whether in the form of a
consolidation, share exchange or otherwise having an aggregate value of $35
million or more; or any sale, transfer, lease or other disposition of 50% or
more of the assets of the Target Company and its subsidiaries or 50% of the
capital stock of the Target Company, in each case, in a transaction or related
series of transactions.

     (b) If the Target Company publicly announces its intention to or enters
into an agreement providing for a Business Transaction on or prior to the end of
the No-Shop Period (the "Transaction Event"), the Target Company shall pay to
the Other Party, in consideration of the time, effort and resources expended in
connection herewith, $2,000,000 (less any amounts paid by the Target Company to
the Other Party pursuant to Section 10.5(c)) plus any fees and expenses incurred
in connection with collecting such amount (the "Transaction Fee"). The
Transaction Fee shall be payable no later than ten business days after the
Transaction Event and shall be made by wire transfer of immediately available
funds to an account designated by the Other Party.

     SECTION 7.7 ADDITIONAL AFFIRMATIVE COVENANT OF MRI. MRI agrees that it
shall, simultaneous with the Effective Date, make a capital contribution to NMR
in such amount, if any, as shall be necessary to permit NMR to make the
termination payments to Joseph G. Dasti and John P. O'Malley which are a
condition to the effectiveness of their respective Non-Competition and
Consulting Agreements referred to in Section 8.7.

     SECTION 7.8 DIRECTORS' AND OFFICERS' INDEMNIFICATION. In the event the
Merger shall become effective, then from and after the Effective Date, MRI and
the Surviving Corporation (the "Indemnifying Parties") shall indemnify, defend
and hold harmless each person who is now, or who becomes prior to the Effective
Date, an officer, director, employee or agent of MRI or NMR (the "Indemnified
Parties") against (i) all losses, claims, damages, cost, expenses, liability or
judgment or amounts paid with the approval of the Indemnifying Party (which
approval shall not be unreasonably withheld) in settlement of or in connection
with any claim, action, suit, proceeding or investigation based in whole or in
part on or arising in whole or in part out of the fact that such person is or
was an officer, director, employee or agent of MRI or NMR, whether pertaining to
any matter existing or occurring at or prior to the Effective Date, and whether
asserted or claimed prior to, at or after, the Effective Date (the "Indemnified
Liabilities") and (ii) all Indemnified Liabilities based in whole or in part on
or arising in whole or in part out of or pertaining to this Agreement or the
transactions contemplated hereby, including, without limitation, any Indemnified
Liabilities arising under or out of any state or federal securities laws, in
each case to the fullest extent permitted by law (and MRI and the Surviving
Corporation, as the case may be, shall pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
fullest extent permitted by law upon receipt of any undertaking that may be
required by law).

after the date of this Agreement, take all action necessary in accordance with
Delaware Law, NASDAQ and their respective Certificates of Incorporation and
By-Laws to convene the Stockholders' Meeting of its stockholders to act on this
Agreement. NMR and MRI shall each use its reasonable best efforts to solicit
from their respective stockholders proxies in favor of the approval and adoption
of this Agreement and to secure the vote or consent of stockholders required by
Delaware Law or NASDAQ to approve and adopt this Agreement, unless otherwise
required by the applicable fiduciary duties of the directors of NMR or MRI, as
determined by such directors in good faith after consultation with independent
legal counsel.

     SECTION 8.2 REGISTRATION STATEMENT; PROXY STATEMENT. (a) As promptly as
practicable after the execution of this Agreement, MRI shall prepare and file
with the SEC a registration statement on Form S-4 (the registration statement,
together with the amendments thereto, being the "Registration Statement"),
containing a proxy statement/prospectus, in connection with the registration
under the Securities Act of the MRI Common Stock constituting the Merger
Consideration and the other transactions contemplated by the Agreement. As
promptly as practicable after the execution of this Agreement, NMR and MRI shall
prepare and file with the SEC a Joint Proxy Statement that will be the same
proxy statement/prospectus contained in the Registration Statement, and a form
of proxy, in connection with the votes of NMR's and MRI's stockholders with
respect to the Merger (such proxy statement/prospectus, together with any
amendments thereof or supplements thereto, in each case in the form or forms
mailed to NMR's and MRI's stockholders, being the "Proxy Statement"). Each of
MRI and NMR will use all reasonable best efforts to have or cause the
Registration Statement to become effective as promptly as practicable, and shall
take any action required to be taken under any applicable federal or state
securities laws in connection with the issuance of shares of MRI Common Stock in
the Merger. Each of MRI and NMR shall furnish all information concerning it and
the holders of its capital stock as the other may reasonably request in
connection with such actions. As promptly as practicable after the Registration
Statement shall have become effective, NMR and MRI shall mail the Proxy
Statement to their respective stockholders. The Proxy Statement shall include

Date, 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

misleading. If at any time prior to the Effective Date any event or circumstance
relating to MRI or any of its affiliates, or its or their respective officers or
directors, should be discovered by MRI which should be set forth in an amendment
to the Registration Statement or a supplement to the Proxy Statement, MRI shall
promptly inform NMR. All documents that MRI is responsible for filing with the
SEC in connection with the transactions contemplated herein will comply as to
form and substance in all material respects with the applicable requirements of

     SECTION 8.3 APPROPRIATE ACTION; CONSENTS; FILINGS. (a) NMR and MRI shall
each use their best efforts to (i) take, or cause to be taken, all appropriate
action, and do, or cause to be done, all things necessary, proper or advisable
under applicable Law or otherwise to consummate, satisfy the conditions to, and
make effective the transactions contemplated by this Agreement, (ii) obtain from
any Governmental Entities or other persons any consents, licenses, permits,
waivers, approvals, authorizations or orders required to be obtained or made by
MRI or

<PAGE>

NMR or any of their subsidiaries in connection with the authorization, execution
and delivery of this Agreement and the consummation of the transactions
contemplated herein, including, without limitation, the Merger, (iii) make all
necessary filings, and thereafter make any other required submissions, with
respect to this Agreement and the Merger required under (A) the Securities Act
and the Exchange Act and the rules and regulations thereunder, and any other
applicable federal or state securities laws, and (B) any other applicable Law;
provided that MRI and NMR shall cooperate with each other in connection with the
making of all such filings, including providing copies of all such documents to
the nonfiling party and its advisors prior to filing and, if requested, to
accept all reasonable additions, deletions or changes suggested in connection
therewith. To assist in obtaining necessary consents from NMR's lenders, MRI Sub
agrees to offer the type and nature of collateral, guaranty and other security
at Closing to secure NMR's existing indebtedness which is no less favorable to
NMR's present lenders than the assets which currently secure the NMR
indebtedness. NMR and MRI shall furnish all information required for any
application or other filing to be made pursuant to the rules and regulations of
any applicable Law (including all information required to be included in the
Proxy Statement and the Registration Statement) in connection with the
transactions contemplated by this Agreement.

     (b) Without limiting the application of Article X hereof and subject to the
respective fiduciary obligations of the directors of NMR and MRI, each of NMR
and MRI agree to cooperate and use their best efforts vigorously to contest and
resist any action, including administrative or judicial action, and to have
vacated, lifted, reversed or overturned any decree, judgment, injunction or
other order (whether temporary, preliminary or permanent) (an "Order") that is
in effect and that restricts, prevents or prohibits the consummation of the
Merger or any other transactions contemplated by this Agreement, including,
without limitation, by vigorously pursuing all available avenues of
administrative and judicial appeal; provided, however, that in no event shall
either party take, or be required to take, any action that would have a NMR
Material Adverse Effect or a MRI Material Adverse Effect.

     (c) Each of NMR and MRI shall give (or shall cause their respective
subsidiaries to give) any notices to third parties, and use, and cause their
respective subsidiaries to use, its best efforts to obtain any third party
consents (i) necessary, proper or advisable to consummate the transactions
contemplated in this Agreement, (ii) disclosed or required to be disclosed in
the NMR Disclosure Schedule or the MRI Disclosure Schedule, as the case may be,
(iii) otherwise required under any contracts, licenses, leases or other
agreements in connection with the consummation of the transactions contemplated
herein or (iv) required to prevent a NMR Material Adverse Effect from occurring
prior to or after the Effective Date or a MRI Material Adverse Effect from
occurring prior to or after the Effective Date.

     (d) In the event that either party shall fail to obtain any third party
consent described in subsection (c) above, such party shall use its best
efforts, and shall take any such actions reasonably requested by the other party
hereto, to minimize any adverse effect upon NMR and MRI, their respective
subsidiaries, and their respective businesses resulting, or which could
reasonably be expected to result, after the Effective Date, from the failure to
obtain such consent.

     SECTION 8.4 AFFILIATES. NMR will advise its affiliates (as such term is
defined in Rule 405 under the Securities Act) of the resale restrictions imposed
by federal securities laws, including Rule 145 under the Securities Act on the
shares of MRI Common Stock received by them pursuant to the Merger, and will use
its best efforts to obtain from each such affiliate a letter stating that such
affiliate is aware of such restrictions.

     SECTION 8.5 PUBLIC ANNOUNCEMENTS. Unless otherwise required by applicable
Law or stock exchange requirements or the requirements of the NASD (and in that
event only if time does not permit), MRI and NMR shall consult with each other
before issuing any press release or otherwise making any public statements with
respect to the Merger and the transactions contemplated thereby and shall not
issue any such press release or make any such public statement prior to such
consultation.

     SECTION 8.6 NASDAQ LISTING. MRI shall use its best efforts to cause the
shares of MRI Common Stock to be issued in connection with the Merger to be
approved for quotation on the NASDAQ-National Market System prior to the
Effective Date.

     SECTION 8.7 EXISTING EXECUTIVE EMPLOYMENT ARRANGEMENTS. NMR shall enter
into agreements with Messrs. Joseph G. Dasti and John P. O'Malley in the form
annexed hereto as Exhibit 8.7A (the "NMR Executive Agreements"). MRI shall enter
into non-competition and consulting agreements with Messrs. Dasti and O'Malley
in the form annexed hereto as Exhibit 8.7B (the "Non-Competition and Consulting
Agreements").

nationally recognized investment banking firm to render its written opinion to
its Board of Directors to the effect that the terms of the Merger are fair, from
a financial point of view, to such party and its stockholders. The firm retained

          (a) by mutual written consent of MRI and NMR;

          (b) by MRI, if any representation or warranty made by NMR in this

          (g) be either MRI or NMR, (i) at any time prior to 11:59 p.m. New York
     City time on June 19, 1996 (or at such later date as mutually agreed upon
     by the parties hereto) (the "Due Diligence Date"), if the results of its

     or (ii) if the written fairness opinion by MRI's or NMR's Financial Advisor
     is not delivered to the appropriate party by June 14, 1996;

other and all rights and obligations of any party hereto shall cease.
Notwithstanding the foregoing, nothing herein shall relieve any party of
liability for failure to perform or comply with any obligation under Sections
7.4 and 7.5 of this Agreement prior to the termination hereof.

approved the Merger in (iii) are herein referred to as a "Non-Breaching Party"),
in consideration of the time, effort and resources expended in connection
herewith, an amount equal to, in the case of a Breach Event, the sum of
$2,000,000, and, in the case of a Non-Approval Event, $1,000,000, plus in all
such cases any fees or expenses incurred by the Non-Breaching Party in
connection with the collection of such amount (the "Collection Expenses").

     (d) Any payment required to be made pursuant to Section 10.5(c) shall be
made to the Non-Breaching Party entitled to receive such payment not later than
ten (10) days after delivery to the other party of notice of demand for payment

Board of Directors
Medical Resources, Inc.
155 State Street
Hackensack, New Jersey 07601

Gentlemen:

  We understand that Medical Resources, Inc. (the "Company") is undertaking a
transaction whereby NMR of America, Inc., a Delaware corporation ("NMR"), will
be merged with and into a wholly owned subsidiary of the Company, pursuant to
the terms of an Agreement and Plan of Merger, dated as of May 20, 1996 (the
"Merger Agreement"), such that NMR becomes a wholly owned subsidiary of the
Company (the "Transaction"). Pursuant to the Transaction, each outstanding share
of NMR's Common Stock, $0.01 par value, shall be converted into 0.6875 shares of
the Company's Common Stock, par value $0.01 per share (the "Consideration"). The
terms and conditions of the Transaction are more fully set forth in the Merger
Agreement.

     You have requested our opinion as to whether the Consideration to be paid
by the Company in the Transaction is fair to the Company, from a financial point
of view.

     In arriving at our opinion, we have, among other things: (i) reviewed
certain publicly available business and historical financial information
relating to the Company and NMR, (ii) reviewed certain financial information and
other data provided to us by the Company that is not publicly available relating
to the business and prospects of the Company, including financial projections
prepared by the management of the Company, (iii) reviewed certain financial
information and other data provided to us by NMR that is not publicly available
relating to the business and prospects of NMR, including financial projections
prepared by the management of NMR, (iv) conducted discussions with members of
the senior managements of the Company and NMR, (v) reviewed publicly available
financial and stock market data with respect to certain other companies in lines
of business we believe to be generally comparable to those of the Company and
NMR, (vi) considered the pro forma effects of the Transaction on the Company's
financial statements and reviewed certain estimates of synergies prepared by the
managements of the Company and NMR, (vii) reviewed the historical market prices
and trading volumes of the common stocks of the Company and NMR, (viii) compared
the financial terms of the Transaction with the financial terms of certain other
transactions which we believe to be generally comparable to the Transaction,
(ix) reviewed the Merger Agreement in the form provided to us, and (x) conducted
such other financial studies, analyses and investigations, and considered such
other information as we deemed necessary or appropriate.

     In connection with our review, we have not independently verified any of
the foregoing information and have, with your consent, relied on its being
complete and accurate in all material respects. In addition, we have not made
any evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of the Company or NMR, nor have we been furnished with any such
evaluation or appraisal. With respect to the financial projections referred to
above, we have assumed, with your consent, that they have been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the Company's and NMR's management as to the future financial
performance of each company. Further, our opinion is based on economic, monetary
and market conditions existing on thedate hereof.

                                      B-1

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Consideration to be paid by the Company in the Transaction is
fair to the Company from a financial point of view.

June 13, 1996

Special Committee of the Board of Directors
NMR of America, Inc.
430 Mountain Avenue
Murray Hill, New Jersey 07974-2732

Gentlemen:

You have requested our opinion as investment bankers as to the fairness, from a
financial point of view, to the holders of the outstanding shares of common
stock, par value $0.01 per share of NMR of America, Inc. (the "Company" or
"NMR") ("NMR Common Stock") (other than Dissenting Shares (as defined in the
Agreement and Plan of Merger by and among Medical Resources, Inc. ("MRII"), MRI
Sub, Inc. ("MRI Sub") and NMR dated May 20, 1996 (the "Agreement"))) of the
proposed Exchange Ratio (as hereinafter defined) in the proposed Transaction (as
hereinafter defined) with MRII. For the purposes of this opinion, the
"Transaction" means the transaction described pursuant to the Agreement.

As more specifically set forth in the Agreement, and subject to certain terms
and conditions thereof, on the Effective Date (as defined in the Agreement) each
share of NMR Common Stock that is issued and outstanding immediately prior to
the Effective Date (other than Dissenting Shares) shall be converted solely into
the right to receive 0.6875 shares of common stock, par value $0.01 per share of
MRII ("MRII Common Stock") (the "Exchange Ratio").

In the ordinary course of its services, Cowen & Company ("Cowen") is regularly
engaged in the valuation and pricing of businesses and their securities and in
advising corporate securities issuers on related matters.

In arriving at our opinion, Cowen has, among other things:

     (1)  reviewed the Company's financial statements for the three fiscal years
          ended March 31, 1996, certain publicly available filings with the
          Securities and Exchange Commission and certain other relevant
          financial and operating data of the Company;

     (2)  reviewed MRII's financial statements for the three fiscal years ended
          December 31, 1995 and the quarter ended March 31, 1996, certain
          publicly available filings with the Securities and Exchange Commission
          and certain other relevant financial and operating data of MRII;

     (3)  reviewed the Agreement;

     (4)  held meetings and discussions with management and senior personnel of
          the Company and MRII to discuss the business, operations, historical
          financial results and future prospects of the Company and MRII;

     (5)  reviewed financial projections furnished to us by the management of
          the Company and MRII, including among other things, the capital
          structure, sales, net income, cash flow, capital requirements and
          other data of the Company and MRII we deemed relevant;

     (6)  reviewed the valuation of the Company and MRII in comparison to other
          similar publicly traded companies;

     (7)  reviewed the historical prices and trading activity of the securities
          of the Company and MRII and compared those trading histories with
          those of other companies which we deemed relevant;

                                      C-1

<PAGE>


     (8)  analyzed the potential pro forma financial effects of the Transaction
          contemplated by the Agreement;

     (9)  reviewed the proposed financial terms of the Transaction and compared
          them with the financial terms of certain other business combinations
          we deemed relevant; and

     (10) conducted such other studies, analysis, inquiries and investigations
          as we deemed appropriate.

Cowen was not requested to, and did not, solicit third party indications of
interest in acquiring the Company.

In rendering our opinion, we relied upon the Company's and MRII's management
with respect to the accuracy and completeness of the financial and other
information furnished to us as described above. We have not assumed any
responsibility for independent verification of such information, including
financial information, nor have we made an independent evaluation or appraisal
of any of the properties or assets of the Company or MRII.

We have acted as financial advisor to the Special Committee of the Board of
Directors of the Company in connection with the Transaction and received a fee
for our services. We also received a fee for rendering this opinion. In
addition, in the ordinary course of its business, Cowen may trade the debt and
equity securities of the Company and MRII for its own account and for the
accounts of its customers, and, accordingly, it may at any time hold a long or
short position in such securities.

On the basis of our review and analysis, as described above, it is our opinion
as investment bankers that the proposed Exchange Ratio is fair, from a financial
point of view, to the holders of NMR Common Stock (other than Dissenting
Shares).

                                                        Very Truly Yours,

                                                         COWEN & COMPANY

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the General Corporation Law of the State of Delaware
("DGCL") empowers the Company to, and the Certificate of Incorporation of the
Company provides that it shall, indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding by any reason of the fact that he is or was a director,
officer, employee or agent of the Company, or is or was serving at the request
of the Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful; except
that, in the case of an action or suit by or in the right of the Company, no
indemnification may be made in respect of any claim, issue or matter as to which
such person shall have been adjudged to be liable for negligence or misconduct
in the performance of his duty to the Company unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine that such person is fairly and reasonably entitled to indemnity
for such expenses which the Court of Chancery or such other court shall deem
proper.

     The Company's Certificate of Incorporation provides, pursuant to Section
145 of the DGCL, for indemnification of officers, directors, employees and
agents of the Company and persons serving at the request of the Company in such
capacities within other business organizations against certain losses, costs,
liabilities and expenses incurred by reason of their position with the Company
or such other business organizations.

     Article Ninth of the Registrant's Certificate of Incorporation limits a
directors liability in accordance with Section 102(b) of the DGCL. Specifically,
Article Ninth provides that no director of the Company shall be liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.
Article Ninth also provides that if the DGCL is further amended to authorize
corporate action further eliminating or limiting the personal liability of
directors, the liability of a director of the Company shall be eliminated or
limited to the fullest extent permitted by the DGCL.

ITEM 22. UNDERTAKING.

     (a) Insofar as indemnifications for liabilities arising under the
Securities Act of 1933, as amended, may be permitted to directors, officers and
controlling persons of the registrant pursuant to the provisions described under
Item 15 above, or otherwise, the registrant has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act of 1933, as amended, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer, or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer, or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933, as amended, and will be
governed by the final adjudication of such issue.

     (b) MRI hereby undertakes:

          (1) to respond to requests for information that is incorporated by
     reference into this Joint Proxy Statement/Prospectus pursuant to Item 4,
     10(b), 11 or 13 of this Form S-4, within one business day of receipt of
     such request, and to send the incorporated documents by first class mail or
     other equally prompt means. This includes information contained in
     documents filed subsequent to the effective date of the Registration
     Statement through the date of responding to the request.

          (2) to supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the Registration Statement when
     it became effective.

          (3)(A) that prior to any public re-offering of the securities
     registered hereunder through the use of a prospectus which is a part of the
     Registration statement, by any person or party who is deemed to be an
     underwriter within the meaning of Rule 145(c) of the Act, such re-offering
     prospectus will contain the information called for by the applicable
     registration form with respect to re-offerings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

     (B) that every prospectus that (i) is filed pursuant to paragraph 3(A)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415 will be filed as part of an amendment to the Registration
Statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Act, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

Gentlemen:

     We refer to the Registration Statement on Form S-4 (the "Registration
Statement") under the Securities Act of 1933, as amended, to be filed by Medical
Resources, Inc., a Delaware corporation (the "Company"), on or about the date
hereof. The Registration Statement covers a maximum of 5,643,673 shares of the
Company's common stock (the "Shares") to be issued in connection with the merger
of NMR of America, Inc. ("NMR") with and into a wholly-owned subsidiary of the
Company ("Sub"), pursuant to the Agreement and Plan of Merger dated May 20, 1996
by and among the Company, Sub and NMR (the "Merger Agreement").

     We have examined the Registration Statement and we further have examined
the Certificate of Incorporation of the Company as certified by the Secretary of
State of the State of Delaware, the By-Laws, the minute books and certain other
agreements of the Company as a basis for the opinion hereafter expressed.

     Based on the foregoing examination, we are of the opinion that when the
Shares have been issued and delivered as contemplated in the Merger Agreement
and the Registration Statement the Shares will be legally issued, fully paid and
non-assessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including any Prospectus constituting a part thereof,
and any amendments thereto.

     This opinion is rendered solely for your benefit in connection with the
transaction described above. This opinion may not be used or relied upon by any
other person without our prior written consent.


                                    Very truly yours,


                                    WERBEL MCMILLIN & CARNELUTTI

MRI Sub, Inc.

Dear Ladies and Gentlemen:

     We have acted as counsel to NMR of America, Inc., a Delaware corporation
("NMR"), in connection with the proposed acquisition of NMR by Medical
Resources, Inc., a Delaware corporation ("MRI"), by means of a merger of MRI
Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of MRI
("Subsidiary"), with NMR, with Subsidiary as the surviving corporation (the
"Merger"). The Merger will be effected pursuant to the provisions of an
Agreement and Plan of Merger dated as of May 20, 1996 by and among MRI,
Subsidiary and NMR (the "Merger Agreement"). Capitalized terms used herein that
are not otherwise defined shall have the meanings given such terms in the Merger
Agreement.

     Pursuant to the Merger Agreement, on the Effective Date, each share of NMR
Common Stock shall be converted into the right to receive 0.6875 of a share of
MRI Common Stock (the "Exchange Ratio"). Further, on the Effective Date, each
outstanding warrant, option, convertible debenture and other right to acquire
shares of NMR Common Stock will automatically be deemed exercisable into shares
of MRI Common Stock in accordance with the Exchange Ratio. No fractional shares
of MRI Common Stock will be issued pursuant to the Merger, and in lieu thereof,


<PAGE>


any holder of NMR Common Stock who would otherwise be entitled to receive a
fractional share of MRI Common Stock will receive an amount of cash
determined by multiplying such fraction by the market price of a share of MRI
Common Stock in accordance with the terms of the Merger Agreement.

     In addition to providing the foregoing facts, you have made the following
additional representations to us with respect to the Merger and have authorized
us to rely on such representations in expressing the opinion set forth below:

     1. The fair market value of the shares of MRI Common Stock to be received
by each stockholder of NMR in connection with the Merger will be approximately
equal to the fair market value of the shares of NMR Common Stock surrendered in
exchange therefor in the Merger.

     2. There is no plan or intention on the part of the stockholders of NMR who
own five percent (5%) or more of the NMR Common Stock and to the best knowledge
of the management of NMR, there is no plan or intention on the part of the
remaining stockholders of NMR, to sell, exchange or otherwise dispose of a
number of shares of MRI Common Stock to be received in the Merger that would
reduce the aggregate value of such MRI Common Stock held by the former NMR
stockholders to less than fifty percent (50%) of the aggregate value of the
outstanding NMR Common Stock immediately prior to the Merger. For purposes of
this representation, shares of NMR Common Stock exchanged for cash in lieu of
fractional shares of MRI Common Stock will be treated as outstanding NMR Common
Stock as of the Effective Date. Moreover, shares of NMR Common Stock held by
stockholders of NMR and otherwise sold, redeemed or disposed of prior or
subsequent to the Merger will be considered in making this representation.

     3. Subsidiary will acquire at least ninety percent (90%) of the fair market
value of the net assets and at least seventy percent (70%) of the fair market
value of the gross assets held by NMR immediately prior to the Merger. For
purposes of this representation, amounts paid by NMR to stockholders who receive
cash or other property, assets of NMR used to pay its reorganizational expenses,
and all redemptions and distributions (except for regular dividends) made by NMR
immediately prior to the Merger are deemed to constitute assets of NMR held
immediately prior to the Merger.

     4. Prior to the Merger, MRI will be in control of Subsidiary within the
meaning of Section 368(c) of the Internal Revenue Code of 1986, as amended (the
"Code").

     5. Following the Merger, Subsidiary will not issue additional shares of its
stock that would result in MRI losing control of Subsidiary within the meaning
of Code Section 368(c).

     6. MRI has no plan or intention to reacquire any of the shares of MRI
Common Stock to be issued to the stockholders


                                     -2-


<PAGE>


of NMR pursuant to the Merger and MRI is under no contractual obligation and has
no contractual right to reacquire any of such shares of MRI Common Stock.

     7. MRI has no plan or intention to liquidate Subsidiary, to merge
Subsidiary with and into another corporation, to sell or otherwise dispose of
the stock of Subsidiary, or to cause Subsidiary to sell or otherwise dispose of
any of the assets of NMR acquired in the Merger, other than the assets located
in NMR's Bel Air, Maryland and Elgin, Illinois centers and except for
dispositions made in the ordinary course of business or for transfers described
in Code Section 368(a)(2)(c).

     8. The liabilities of NMR assumed by Subsidiary in the Merger and the
liabilities to which the NMR assets transferred to Subsidiary in the Merger are
subject were incurred by NMR in the ordinary course of business.

     9. Following the Merger, Subsidiary will continue the historic business of
NMR or use a significant portion of NMR's business assets in a business.

     10. MRI, Subsidiary, NMR and the shareholders of NMR will pay their
respective expenses, if any, incurred in connection with the transaction.

     11. There is no intercorporate indebtedness existing between NMR and MRI
that was issued, acquired or will be settled at a discount in connection with
the Merger.

     12. No two parties to the transaction are investment companies as defined
in Code Section 368(a)(2)(F)(iii).

     13. NMR is not under the jurisdiction of a court in a Title 11 or similar
case within the meaning of Code Section 368(a)(3)(A).

     14. The fair market value of the assets of NMR transferred to Subsidiary in
the Merger will equal or exceed the sum of NMR liabilities assumed by Subsidiary
in the Merger, plus the amount of liabilities, if any, to which the transferred
assets are subject.

     15. No stock of Subsidiary will be issued in the Merger.

     16. The total cash consideration that will be paid in the Merger to NMR
stockholders in lieu of fractional shares of MRI Common Stock will not exceed
one percent (1%) of the aggregate consideration that will be issued to NMR
stockholders


                                     -3-


<PAGE>


with respect to their shares of NMR Common Stock surrendered in the Merger.

     17. None of the compensation for services rendered to be received by any
employee of NMR who is also a stockholder of NMR is consideration for, or
allocable to, such employee/stockholder's shares of NMR Common Stock exchanged
in the Merger.

     18. The Merger is based upon and motivated by valid business purposes
unrelated to the avoidance of Federal income taxes and will comply in all
respects with the laws of the states of incorporation of the corporations
involved in the Merger.

     19. In the Merger, the stockholders of NMR will exchange for voting stock
of MRI an amount of voting stock of NMR which constitutes control of NMR under
Section 368(c) of the Code.

                             LIMITATIONS ON OPINION

     Our opinion expressed herein is based exclusively upon the facts and
representations set forth above and in the Joint Proxy Statement/Prospectus of
MRI and NMR dated ____________________, upon which we have relied. To the extent
any of the facts or representations relied upon by us are inaccurate for any
reason, the opinion set forth below would necessarily have to be modified in
whole or in part or may be rendered undeliverable.

     Additionally, our opinion is based upon our interpretation of the Code, the
applicable United States Treasury Department Regulations promulgated or proposed
thereunder (the "Regulations"), current positions of the Internal Revenue
Service (the "Service") contained in published revenue rulings and revenue
procedures, current administrative positions of the Service and existing
judicial decisions, all of which are subject to change or modification at any
time. Any future amendments to the Code or the Regulations or new Federal
judicial decisions or administrative interpretations (any of which could be
retroactive in effect) could cause the opinion set forth herein to require
modification in whole or in part or render it undeliverable. No opinion is
expressed herein with regard to the Federal tax consequences of the Merger under
any Section of the Code except if and to the extent such section is specifically
referenced below.


                                       -4-


<PAGE>


                                     OPINION

     Based solely upon the referenced facts and representations, and assuming
that the Merger occurs in accordance with the Merger Agreement (and taking into
consideration the limitations set forth above and at the end of this opinion),
it is our opinion that under current Federal law:

     1. The Merger will be a reorganization within the meaning of Code Sections
368(a)(1)(A) and 368(a)(2)(D). MRI, Subsidiary and NMR will each be considered a
"party to a reorganization" within the meaning of Code Section 368(b).

     2. No gain or loss will be recognized for Federal income tax purposes by
NMR on the transfer of its assets to Subsidiary and the assumption by Subsidiary
of NMR's liabilities pursuant to the Merger. Code Sections 361(a) and 357(a).

     3. No gain or loss will be recognized by the stockholders of NMR whose NMR
Common Stock is converted solely into MRI Common Stock in connection with and
pursuant to the Merger. Code Section 354(a).

     4. The tax basis of the shares of MRI Common Stock received by the
stockholders of NMR in exchange for NMR Common Stock in the Merger will be
equal, in each instance, to the adjusted tax basis of the shares of NMR Common
Stock surrendered by such stockholders in exchange therefor. Code Section
358(a).

     5. The holding period of the shares of MRI Common Stock received by the
stockholders of NMR in connection with the Merger will include, in each
instance, the period during which the shares of NMR Common Stock surrendered in
exchange therefor were held by such stockholders if, and to the extent that, the
shares of NMR Common Stock were capital assets in the hands of the NMR
stockholders on the Effective Date of the Merger. Code Section 1223(1).

     6. The NMR stockholders receiving cash in lieu of fractional shares of MRI
Common Stock will be treated as if such fractional shares had been issued by MRI
and then subsequently redeemed by MRI and will be taxed on any resulting gain in
an amount which shall not exceed the amount of the cash received. Code Section
356(a). Whether the cash received by such NMR stockholders in lieu of fractional
shares is characterized as a dividend or as a payment in exchange for NMR Common
Stock will depend on whether the distribution of cash to such stockholders when
viewed as part of the reorganization as a whole and as a redemption by MRI (and
applying principles analogous to those set forth in Code Section 302(b)) more
closely resembles a dividend distribution or a payment in exchange for shares of
NMR Common Stock surrendered in exchange therefor.

     It should be noted that a successful IRS challenge to the status of the
Merger as a reorganization within the meaning


                                     -5-


<PAGE>


of Code Section 368 would result in each NMR stockholder recognizing gain
or loss with respect to each share of NMR Common Stock surrendered equal to the
difference between the stockholder's tax basis in such share and the fair market
value, as of the time of the Merger, of the MRI Common Stock received in
exchange therefor. Even if the Merger qualifies as a reorganization within the
meaning of Section 368(a)(1)(A) and Section 368(a)(2)(D) of the Code, a
recipient of shares of MRI Common Stock may recognize income, gain or loss to
the extent such shares are considered to have been received in exchange for
services or property (i.e., as consideration for services or property other than
solely shares of NMR Common Stock).

     No opinion is expressed herein with respect to the tax consequences of the
Merger to the holders of outstanding NMR warrants, options, convertible
debentures and other rights to acquire shares of NMR Common Stock, including,
without limitation, the acceleration of any exercise provisions under such
rights and/or securities as a consequence of the Merger.

     This opinion represents our views as to the interpretation of existing law
and cannot be taken as an assurance as to the manner in which the law will
subsequently develop. Accordingly, no assurance can be given that the Service
will not alter its present positions either prospectively or retrospectively, or
will not adopt new positions with regard to any of the matters upon which we are
rendering an opinion, nor can any assurance be given that the Service will not
audit NMR or its shareholders and/or question or challenge the opinion expressed
herein. The Service is in no way bound by the opinion expressed herein.


                                             Very truly yours,






                                       -6-

all business opportunities without limitation.

devotion of efforts based out of the Company's Hackensack or Murray Hill, New

for a period of 18 months from the Effective Date (the "Restrictive Period"),
Consultant will not, directly or indirectly, as principal, agent, employee,
officer, director or shareholder (except as an investor in securities of
publicly-owned corporations so long as Consultant's ownership of stock of any
one company does not exceed 5% of the outstanding stock of said company) engage
in any business or enterprise in the United States which is competitive with the
business heretofore conducted or hereafter conducted by the Company or any
present subsidiary or affiliate of the Company, including any business or
enterprise involving magnetic resonance imaging or


                                     -3-

contained in this Section 5.1 shall no longer apply, and shall be of no further
force and effect, in the event the Consultant terminates this Agreement pursuant

Section 5.1 shall prevent Consultant from engaging in any business or enterprise
as principal, agent, employee, officer, director or shareholder of any entity
which, as its primary business, performs clinical laboratory services or engages
in the testing, development or manufacturing of pharmaceutical products, so long
as such entity does not engage in diagnostic imaging services.

     5.2 Severability. If, in any judicial proceeding, the duration or scope of
any covenant or agreement of Consultant contained in this Section 5 shall be
adjudicated to be invalid or unenforceable, the parties agree that this
Agreement shall be deemed amended to reduce such duration or scope to the extent
necessary to permit enforcement of such covenant or agreement, such amendment to
apply only with respect to the operation of such covenant and agreement in the
particular jurisdiction in which such adjudication is made.

     5.3 Trade Secrets. Other than in the performance of his duties hereunder,
during the Restrictive Period, Consultant agrees not to disclose, to any person,
firm or corporation any information (whether or not in written or tangible form)
concerning the business and marketing methods, referral contacts, physician
relationships, vendor relationships, projection and budgets, costs and expenses
and similar confidential information of the Company (all such information being
referred to in this Agreement as "Trade Secrets"). Consultant shall not deliver,
reproduce or in any way allow such Trade Secrets to be delivered or used by any
third party during the Restrictive Period without specific direction or consent
of the Board of Directors of the Company. Consultant hereby assigns to the
Company any rights which he may have in any such Trade Secret during the

Company; provided, however, that the restrictions contained in this Section 5.4
shall no longer apply, and shall be of no further force and effect, upon
termination of this Agreement by Consultant pursuant to Section 6.3.

     5.5 Injunctive Relief. The parties hereto acknowledge and agree that money
damages would constitute an inadequate remedy in the event of a breach of this
Section 5 and that in addition to any other remedies which may be available, the
obligations of Consultant under this Section 5 shall be specifically
enforceable.

failure 10 days after written notice specifying such breach, repudiation or
failure.

renew or extend the term of this Agreement. None of (i) the expiration of the
Term, or (ii) the failure or refusal of the Company to renew or extend the Term
or Consultant's retention by the Company after the expiration of the Term shall
be deemed to constitute a termination of this Agreement by the Company "without
cause" for the purpose of triggering any rights of or cause of action by
Consultant; provided, however, in the event that the Company wishes to renew
this Agreement, it shall provide written notice to the Consultant ninety (90)
days prior to the termination of the Agreement and the Company and the

business heretofore conducted or hereafter conducted by the Company or any
present subsidiary or affiliate of the Company, including any business or
enterprise involving magnetic resonance imaging or other diagnostic imaging
procedure; provided, however, that the restrictions contained in this Section
5.1 shall not apply, and shall be of no force and effect, in the event the
Consultant terminates this Agreement pursuant to Section 6.3(a) hereof; and
provided, further, that nothing contained in this Section 5.1 shall prevent
Consultant from engaging in any business or enterprise as principal, agent,
employee, officer, director or shareholder of any entity which, as its primary
business, performs clinical laboratory services or engages in the testing,

necessary to permit enforcement of such covenant or agreement, such amendment to
apply only with respect to the operation of such covenant and agreement in the
particular jurisdiction in which such adjudication is made.

the Company or induce, encourage or request, directly or indirectly, any person
or entity engaged in business with the Company, including, but not limited to,
referring physicians, technicians, medical providers, health organizations or
lenders, to reduce the amount of business engaged in with the Company; provided,
however, that the restrictions contained in this Section 5.4 shall no longer
apply, and shall be of no further force and effect, in the event the Consultant
terminates this Agreement pursuant to Section 6.3(a) hereof.

     5.5 Injunctive Relief. The parties hereto acknowledge and agree that money
damages would constitute an inadequate remedy in the event of a breach of this

<PAGE>

cause by the Company and any other termination of Consultant's engagement

Section 6.6 hereof.

     6.3 Termination For Cause by Consultant; After 18 months. (a) Consultant
shall have the right and option, exercisable by giving written notice to the

such breach, repudiation or failure 10 days after written notice specifying such
breach, repudiation or failure.

     (b) Notwithstanding anything otherwise contained herein to the contrary,
Consultant may, at his election, terminate this Agreement 18 months after the
Effective Date in which event the Company shall be subject to the requirements
of Section 6.6.

     6.4 No Obligation to Renew, Etc. The Company shall have no obligation to
renew or extend the term of this Agreement beyond the Term. None of (i) the
expiration of the Term or (ii) the failure or refusal of the Company to renew or
extend the Term or Consultant's retention by the Company after the expiration of
the Term, shall be deemed to constitute a termination of this Agreement by the
Company "without cause" for the purpose of triggering any rights of or cause of
action by Consultant; provided, however, that in the event the Company wishes to
renew this Agreement, it shall provide written notice to the Consultant nine (9)
months prior to the termination of the Agreement and the Company and the
Consultant shall use their best efforts to negotiate a mutually satisfactory
agreement within forty-five (45) days following such notice.

terminated by Company for cause pursuant to Section 6.2, Consultant's right to

seven calendar days following the effective date of such termination all unpaid
fees payable pursuant to Section 3.1 which shall have accrued as of the
effective date of such termination;

     (3) The provisions of Section 7 and Section 3.5 shall continue in
accordance with their terms.

(including, without limitation, termination by reason of death or disability),
(ii) at the election of Consultant 18 months after the Effective Date pursuant
to Section 6.3(b), or (iii) pursuant to Section 6.3(a), Consultant (or his legal
representatives or estate in the case of disability or death) shall be entitled
to payment of (A) all amounts payable during the Term pursuant to Section 3 of
this Agreement as though this Agreement had not been terminated prior to the end
of the Term and (B) his unpaid reimbursable expenses payable in accordance with
Section 3.2 hereof (except that in the case of termination under clause (ii),
Consultant shall be entitled to such amounts payable pursuant to Section 3 so
long as he is not in breach of his obligations under Section 5 hereunder); and
the provisions of Section 7 shall continue in accordance with their terms.

Consultant shall be entitled to payment of (i) all amounts payable during the
Term pursuant to Section 3 of this Agreement as though this Agreement had not
been terminated prior to the end of the Term, except that with respect to the
amount of any of the first 18 monthly payments following the Effective Date
which become payable after the date this Agreement is terminated by Consultant
under this Section 6.6(b), the amount of each such monthly payment shall be
reduced by $11,111; and (ii) his unpaid reimbursable expenses payable in
accordance with Section 3.2 hereof; and the provisions of Section 7 shall
continue in accordance with their terms.
