PRESS RELEASE
 
Medical Resources, Inc. Announces Agreement-in-Principle To Settle Class Action
Law Suits
 
HACKENSACK, N.J., Dec. 21 /PRNewswire/--Medical Resources, Inc. (Nasdaq: MRII)
today announced that it has reached an agreement-in-principle to settle all of
the consolidated class action lawsuits currently pending against the Company.
Under the terms of the agreement-in-principle, which is subject to approval by
the federal court in the District of New Jersey at a hearing expected to be held
in late February or in March of 1999, the plaintiffs in the class actions will
receive, in full settlement of their claims, $2.75 million in insurance proceeds
and $5.25 million of Convertible Subordinated Notes newly-issued by the Company.
 
The $5.25 million of Convertible Subordinated Notes will bear interest at the
rate of 8% per annum, will be due on the earlier of August 1, 2005 or when the
Company's presently outstanding Senior Notes are paid in full, and may be
prepaid in cash by the Company at any time after issuance subject to the payment
of a prepayment premium which begins at 8% and decreases over time.
Additionally, the Convertible Subordinated Notes will be convertible into shares
of the Company's Common Stock beginning February 15, 2000 at a price per share
equal to the greater of $3.00 or 120% of the ten day average closing price of
the Company's Common Stock as of the court hearing date.
 
The agreement-in-principle and the class action settlement contemplated thereby
are further subject to (1) consent to the issuance of the Convertible
Subordinated Notes by the Company's Senior Note lenders and (2) the right of
either the Company or the attorneys representing the class plaintiffs to
terminate the agreement-in-principle if the ten day average closing price of the
Company's Common Stock as of the court hearing date is less than $1.75 per
share.
 
Medical Resources specializes in the ownership, operation and management of
fixed-site outpatient medical diagnostic imaging centers. The Company operates
more than 90 imaging centers in the U.S. and provides network management
services to managed care organizations in regions where its centers are

Note: This release contains forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Investors are cautioned that
forward-looking statements are inherently uncertain. Actual performance and
results may differ materially from that projected or suggested herein due to
certain risks and uncertainties including, without limitation: the ability of
the Company to effectively integrate the operations and information systems of
businesses acquired in 1997 and earlier; the ability of the Company to generate
net positive cash flows from operations; the payment timing and ultimate
collectibility of accounts receivable (including purchased accounts receivable)
from different payer groups (including Personal Injury type); the economic
impact of involuntary share repurchases and other payments (including price
protection payments and penalty payments) caused by the delay in the
effectiveness of the Company's Registration Statement and by the decline in the
Company's share price; the potential dilution that would result from the
conversion of the Company's Series C Convertible Preferred Stock into common
shares at current share prices; the impact of a changing mix of managed care and
personal injury claim business on contractual allowance provisions, net revenues
and bad debt provisions; the ultimate economic impact of recent litigation
including shareholder and former management lawsuits against the Company and
certain of its Directors; the availability of debt and/or equity capital, on
reasonable terms, to finance operations as needed and to finance growth; and the
effects of federal and state laws and regulations on the Company's business over
time. Additional information concerning certain risks and uncertainties that
could cause actual results to differ materially from that projected or suggested
is contained in the Company's filings with the Securities and Exchange
Commission (SEC) over the last 12 months, copies of which are available from the
SEC or from the Company upon request.

PRESS RELEASE
 
Medical Resources Granted Hearing Before Nasdaq Panel
 
Hackensack, NJ, January 15, 1999--Medical Resources, Inc. (NASDAQ: MRII) today
announced that it has been granted a hearing before the Nasdaq Qualifications
Hearing Panel relating to its request to move its stock listing from the Nasdaq
National Market System to the Nasdaq SmallCap Market. The hearing is expected to
occur during the third or fourth week of March, 1999. Until then, the Company's
listing will remain on the Nasdaq National Market System.
 
The Company previously announced that Nasdaq is reviewing it for continued
listing on the National Market System due to its failure to meet the $5.00
minimum bid price requirement. The Company also previously announced that it
would attempt to move its listing to the Nasdaq SmallCap Market if it were
unable to meet the requirements for continued listing on the National Market
System. Notwithstanding the foregoing and the grant of a hearing, no assurance
can be given that the Company will be successful in maintaining its listing on
the National Market System or in moving its listing to the SmallCap Market.
 
Medical Resources specializes in the ownership, operation and management of
fixed-site outpatient medical diagnostic imaging centers. The Company operates
more than 90 imaging centers in the U.S. and provides network management
services to managed care organizations in regions where its centers are
concentrated.

1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
    The accompanying unaudited consolidated financial statements of Medical
Resources, Inc. (the "Company") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete consolidated financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation have been included.
Operating results for the interim periods are not necessarily indicative of the
results that may be expected for an entire year.
 
    The unaudited consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
contained in the Company's Annual Report on Form 10-K filed with the Securities
and Exchange Commission (the "SEC") for the year ended December 31, 1997, as
amended, and in conjunction with Form S-1 declared effective by the SEC on
October 1, 1998.
 
    In July 1998, the Company's shareholders approved a reverse stock split of
the Company's outstanding shares of Common Stock. As a result of the reverse
stock split, each three outstanding shares of Common Stock were automatically
converted into one share of new Common Stock. The share data included in this
Form 10-Q have been adjusted to reflect the impact of the reverse stock split.
 
    The Company has been notified by NASDAQ that it is being reviewed for
continued listing on NASDAQ's National Market System due to its failure to
continue to meet the $5.00 minimum bid price requirement. The Company has until
January 15, 1999 to satisfy the listing requirements. In the event it is unable
to meet the requirements for continued listing on the National Market System,
the Company will attempt to move its listing to NASDAQ's SmallCap Market. No
assurance can be given that the Company will be successful in that regard.
 
THE COMPANY
 
    The Company operates and manages primarily fixed-site, free-standing
outpatient medical diagnostic imaging facilities (herein referred to as
"centers"), and provides diagnostic imaging network management services to
managed care providers. The Company, through its wholly owned subsidiary, Dalcon
Technologies, Inc., also develops and markets software products and systems for
the diagnostic imaging industry.
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold the stock of StarMed
to RehabCare Group, Inc. (the "StarMed Sale"). Due to the StarMed Sale, the
results of operations of StarMed are herein reflected in the Company's
Consolidated Statements of Operations as discontinued operations (see Note 6).
 
REVENUE RECOGNITION
 
    At each of the Company's diagnostic imaging centers, all medical services
are performed exclusively by physician groups (the "Physician Group" or the
"Interpreting Physician"), generally consisting of

radiologists with whom the Company has entered into independent contractor
agreements. Pursuant to these agreements, the Company has agreed to provide
equipment, premises, comprehensive management and administration, including
responsibility for billing and collection of receivables, and technical imaging
services to the Interpreting Physician.
 
    Net service revenues are reported, when earned, at their estimated net
realizable amounts from patients, third party payors and others for services
rendered at contractually established billing rates which generally are at a
discount from gross billing rates. Known and estimated differences between
contractually established billing rates and gross billing rates ("contractual
allowances") are recognized in the determination of net service revenues at the
time services are rendered. Subject to the foregoing, the Company's imaging
centers recognize revenue under one of the three following types of agreements
with Interpreting Physicians:
 
    Type I--The Company receives a technical fee for each diagnostic imaging
    procedure performed at a center, the amount of which is dependent upon the
    type of procedure performed. The fee included in revenues is net of
    contractual allowances. The Company and the Interpreting Physician
    proportionally share in any losses due to uncollectible amounts from
    patients and third party payors, and the Company has established reserves
    for its share of the estimated uncollectible amount.
 
    Type II--The Company bills patients and third party payors directly for
    services provided and pays the Interpreting Physicians either (i) a fixed
    percentage of fees collected at the center, or (ii) a contractually fixed
    amount based upon the specific diagnostic imaging procedures performed.
    Revenues are recorded net of contractual allowances and the Company accrues
    the Interpreting Physician fee as an expense on the Consolidated Statements
    of Operations. The Company bears the risk of loss due to uncollectible
    amounts from patients and third party payors, and the Company has
    established reserves for the estimated uncollectible amount.
 
    Type III--The Company receives from an affiliated physician association a
    fee for the use of the premises, a fee per procedure for acting as billing
    and collection agent and a fee for administrative and technical service
    performed at the centers. The affiliated physician association contracts
    with and pays directly the Interpreting Physicians. The Company's fee, net
    of an allowance based upon the affiliated physician association's ability to
    pay after the association has fulfilled its obligations (i.e.,   estimated
    future net collections from patients and third party payors less facility
    lease expense and Interpreting Physicians fees), constitutes the Company's
    net service revenues. Since the Company's net service revenues are dependent
    upon the amount ultimately realized from patient and third party
    receivables, the Company's revenue and receivables have been reduced by an
    estimate of patient and third party payor contractual allowances, as well as
    an estimated provision for uncollectible amounts from patients and third
    party payors.
 
    Revenues derived from Medicare and Medicaid are subject to audit by such
agencies. The Company is not aware of any pending audits.
 
    The Company also recognizes revenue from the sale of radiology information
systems. Such revenues are recognized on an accrual basis as earned.

RECLASSIFICATION AND RESTATEMENT
 
    The Consolidated Statement of Operations for the nine month period ended
September 30, 1997 has been restated to include a non-cash charge of $2,305,000
for compensation expense resulting from stock options granted in 1996 and early
1997 that were approved by the Company's stockholders in May 1997. In addition,
certain prior year amounts have been reclassified to conform to the current year
presentation.
 
COMPREHENSIVE INCOME
 
    Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130").
SFAS No. 130 requires an entity to report comprehensive income and its
components and increases financial reporting disclosures. This standard has no
impact on the Company's financial position, cash flows or results of operations
since the Company's comprehensive income is the same as its reported net income.
 
EARNINGS PER SHARE
 
    Effective for the year ended December 31, 1997, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share." This statement requires the presentation of Basic Earnings per Share and
Diluted Earnings per Share. Basic earnings per share is based on the weighted
average number of common shares outstanding during the period. Diluted earnings
per share is based on the weighted average number of common shares outstanding
during the period plus the potentially issuable common shares related to
outstanding stock options, warrants and convertible debt. Earnings per share
amounts for the three and nine months ended September 30, 1997 have been
restated to conform to the requirements of SFAS No. 128.

2. BASIS OF FINANCIAL STATEMENT PRESENTATION AND ISSUES AFFECTING LIQUIDITY
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company was in default of certain financial covenants
under its $78,000,000 of Senior Notes. The financial covenant defaults under the
Senior Note agreements entitled the lenders to exercise certain remedies
including acceleration of repayment. In addition, certain medical equipment
notes, and operating and capital leases of the Company (the "Cross-Default
Debt"), contain provisions which allow the creditors or

lessors to accelerate their debt or terminate their leases and seek certain
other remedies if the Company is in default under the terms of agreements such
as the Senior Notes.
 
    In the event that the Senior Note lenders or the holders of the Cross
Default Debt elected to exercise their right to accelerate the obligations under
the Senior Notes or the other loans and leases, such acceleration would have had
a material adverse effect on the Company, its operations and its financial
condition. Furthermore, if such obligations were accelerated, in whole or in
part, there could be no assurance that the Company would have been successful in
identifying or consummating financing necessary to satisfy the obligations which
would have become immediately due and payable. As a result of the uncertainty
related to the defaults and corresponding remedies described above, the Senior
Notes and the Cross Default Debt were shown as current liabilities on the
Company's Consolidated Balance Sheets at December 31, 1997. As a result of these
matters, as well as other issues, there was substantial doubt about the
Company's ability to continue as a going concern. The report of the Company's
independent auditors, Ernst & Young LLP, on the consolidated financial
statements of the Company for the year ended December 31, 1997 contains an
explanatory paragraph with respect to these issues. The December 31, 1997
financial statements did not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    In October 1998, management reached an agreement with the Senior Note
lenders with respect to a waiver of all existing covenant defaults and a
modification of the financial covenants applicable over the remaining term of
the Senior Notes. In consideration for this waiver and amendment, the Company
has agreed to increase the effective blended interest rate on the Senior Notes
from 7.87% to 9.00%, and issued to the Senior Note lenders warrants to acquire
375,000 shares of the Company's Common Stock at an exercise price of $7.67 per
common share. The warrants had an estimated value of $503,000 which will be
recorded as deferred financing expense and amortized over the remaining term of
the Senior Notes. In addition, the Company prepaid $2,000,000 of principal
outstanding on the Senior Notes (without premium) and paid a fee to the Senior
Note lenders of $500,000. As a result of the execution of the waiver and
amendment with respect to the Senior Notes, the Senior Notes and the Cross
Default Debt are no longer in default and have been shown as long-term debt in
the September 30, 1998 Consolidated Balance Sheet.
 
3. UNUSUAL CHARGES
 
    In July 1998, the Company completed a review of under-performing centers and
determined that it would sell or close eight imaging centers during the third
and fourth quarters of 1998. In most cases, the Company decided to sell or close
these centers due to general competitive pressures and because of their close
proximity to other imaging centers of the Company which have more advanced
imaging equipment. During the three months ended September 30, 1998, the Company
recorded unusual charges attributable to center closings of $3,489,000,
consisting of (i) $1,602,000 for the estimated costs to exit equipment lease and
maintenance agreements and facility lease agreements, (ii) $1,481,000 for the
write-off of fixed assets, goodwill and other intangibles and other assets, and
(iii) $406,000 for estimated equipment removal, facility restoration and related
costs.
 
    In addition, other unusual charges were recorded during the three months
ended September 30, 1998 of $890,000, consisting of (i) $380,000 for
professional fees attributable to obtaining the waiver and amendment under the
Company's Senior Note obligations, (ii) $360,000 for penalties associated with
the

delay in the effectiveness of the Company's Registration Statement (which has
now become effective) and (iii) $150,000 for defense costs relating to
shareholder and employee lawsuits.
 
    During the nine months ended September 30, 1998, the Company recorded
unusual charges attributable to center closings of $3,489,000, as described
above, and other unusual charges of $6,290,000, including the $890,000 recorded
during the third quarter of 1998. The other unusual charges consist of (i)
$3,827,000 ($1,194,000 of which was a non-cash charge related to the issuance of
117,000 common stock warrants) for penalties associated with the delay in the
effectiveness the Company's Registration Statement (which has now become
effective), (ii) $863,000 for defense costs relating to shareholder and employee
lawsuits, (iii) $883,000 for costs associated with the investigation of related
party transactions which was concluded in April 1998, (iv) $380,000 for
professional fees attributable to obtaining the waiver and amendment under the
Company's Senior Note obligations and (v) $337,000 for management termination
benefits and related costs.
 
    The Company could incur a substantial additional amount of unusual charges
during the remainder of 1998 depending upon the outcome of shareholder and
employee lawsuits and current negotiations with the holders of the Series C
Preferred Stock regarding additional penalties associated with the failure to
timely register the Company's Common Stock.

    Accounts receivable is net of contractual allowances, which represent
standard fee reductions negotiated with certain third party payors. Contractual
allowances amounted to approximately $32,849,000 and $25,712,000 for the three
months ended September 30, 1998 and 1997, respectively, and approximately
$92,114,000 and $56,805,000 for the nine months ended September 30, 1998 and
1997, respectively.
 
5. COMMITMENTS AND CONTINGENCIES
 
    Between November 1997 and January 1998, several lawsuits were commenced
against the Company, certain of the Company's Directors and certain officers
concerning certain related party transactions that have since been investigated
by a Special Committee of the Board of Directors ("Special Committee"). The
complaints in each action assert that the Company and the named defendants
violated Section 10(b)
 
                                       11

and 20(a) of the Securities Exchange Act of 1934, alleging that the Company
omitted and/or misrepresented material information in its public filings,
including that the Company failed to disclose that it had entered into
acquisitions that were not in the best interest of the Company, that it had paid
unreasonable and unearned acquisition and financial advisory fees to related
parties, and that it concealed or failed to disclose adverse material
information about the Company. Each action seeks unspecified compensatory
damages, with interest, and the costs and expenses incurred in bringing the
action. On February 9, 1998, the above-mentioned class actions were consolidated
for all purposes in federal district court in New Jersey. On March 31, 1998, the
lead plaintiffs in the consolidated class actions served their Consolidated
Class Action Complaint, asserting that the Company and the named defendants
violated Section 10(b) of the Exchange Act, and that certain named defendants
violated Sections 20(a) and 20A of the Exchange Act. The Company intends to
defend vigorously against the allegations.
 
    The Special Committee issued the results of its investigation and certain
recommendations in a report to the Company's Board of Directors and on April 6,
1998, the Company's Board of Directors voted to adopt the recommendations
contained in the report. Accordingly, the Special Committee recommended and 712
Advisory Services, Inc., a financial advisory firm and affiliate of the
Company's Chairman of the Board (the "Affiliate"), agreed to reimburse the
Company approximately $1,424,000 in fees for transactions completed after June
1, 1997, to reimburse $112,500 of the retainer paid to the Affiliate for 1997,
to waive payment of an additional $112,500 of fees accrued by the Company for
the third and fourth quarters of 1997, and to pay a substantial amount of the
expenses associated with the Special Committee's investigations. All such
amounts have been paid or reimbursed to the Company. In addition, the Special
Committee recommended and the Affiliate agreed to allow the Company to terminate
its relationship with the Affiliate.
 
    The Special Committee reported to the directors that it had determined that:
(i) there was no evidence of any federal or state crimes or securities law
violations in connection with the related party transactions in question; (ii)
all related-party matters were disclosed in public filings; (iii) the Affiliate
performed acquisition advisory services fully consistent with the expectations
and understanding of the committee of outside directors that had approved the
Affiliate's acquisition fees; and (iv) the acquisition advisory fees paid to the
Affiliate in connection with the Company's acquisitions in 1997 were within the
range of customary acquisition advisory fees paid to investment bankers on
transactions of similar size.
 
    As previously announced by the Company, the U.S. Attorney for the District
of New Jersey commenced an investigation in connection with the disclosures
regarding the related party transactions referred to above. In addition, the
Company has also received an inquiry from the SEC, but there have been no formal
proceedings commenced by the SEC. The Company has cooperated fully with these
authorities and provided all information requested by them.
 
    On November 7, 1997, the Company accepted the resignations of William D.
Farrell, as President and Chief Operating Officer of the Company and as
Director, and Gary I. Fields, as Senior Vice President and General Counsel. On
the same date, Messrs. Farrell and Fields filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and the
members of the Company's Board of Directors, claiming retaliatory discharge
under the New Jersey Conscientious Employee Protection Act and breach of
contract. On December 17, 1997, the plaintiffs amended their complaint to add a
claim for violation of public policy. The plaintiffs allege that they were
constructively terminated as a result of their objection to certain
related-party transactions, the purported failure of the defendants to
adequately disclose the circumstances surrounding such transactions, and the
Company's public issuance of alleged

false and misleading accounts concerning or relating to such related-party
transactions. The plaintiffs seek unspecified compensatory and punitive damages,
interest and costs and reinstatement of the plaintiffs to their positions with
the Company. On April 8, 1998, the Company filed its Answer to the Amended
Complaint, and asserted a counterclaim against Messrs. Farrell and Fields for
breach of fiduciary duties. The Company intends to defend vigorously against the
allegations.
 
    On November 8, 1997, the Company removed John P. O'Malley III, the Company's
Chief Financial Officer, for failure to fulfill certain of his functions as
Chief Financial Officer. Mr. O'Malley has filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and members
of the Board of Directors, as defendants, claiming retaliatory discharge under
the New Jersey Conscientious Employee Protection Act and defamation. Mr.
O'Malley alleges that the Company terminated his employment in retaliation for
voicing the concerns of shareholders and senior management regarding
related-party transactions and because the Company did not want to make full and
adequate disclosure of the facts and circumstances surrounding such
transactions. In addition, Mr. O'Malley alleges that the Company published false
and defamatory statements about him. Mr. O'Malley seeks unspecified compensatory
and punitive damages, interest and costs of bringing the action. On April 8,
1998, the Company filed its Answer to the Complaint, and asserted a counterclaim
against Mr. O'Malley for breach of fiduciary duties. The Company intends to
defend vigorously against the allegations.
 
    The legal proceedings described above are in their preliminary stages.
Although the Company believes it has meritorious defenses to all claims against
it, the Company is unable to predict with any certainty the ultimate outcome of
these proceedings.
 
    In 1996, Lavina Orsi and Pompeo Orsi brought an action in the Supreme Court
of the State of New York, King's County against Advanced MRA Imaging Associates
in Brooklyn, New York, a wholly owned subsidiary of the Company ("MRA Imaging"),
for damages aggregating $12,500,000. The plaintiff alleges negligent operations,
improper supervision and hiring practices and the failure to operate the
premises in a safe manner, as a result of which the individual suffered physical
injury. The Company's general liability and professional negligence insurance
carriers have been notified, and it has been agreed that the general liability
insurance will pursue the defense of this matter, however, such insurers have
reserved the right to claim that the scope of the matter falls outside the
Company's coverage. The parties to this matter are engaged in discovery. The
Company believes it has meritorious defenses to all claims against it and
therefore is of the opinion that the Company will not incur any material
settlement cost, net of insurance proceeds (if any). Accordingly, the Company
has made no accrual for any costs associated with such litigation under SFAS No.
5.
 
    In the normal course of business, the Company is subject to claims and
litigation other than those set forth above. Management believes that such other
litigation will not have a material adverse effect on the Company's financial
position, cash flows or results of operations. Accordingly, the Company has made
no accrual for any costs associated with such litigation under SFAS No. 5.
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration, the Company
granted rights to have such shares registered for resale pursuant to the federal
securities laws. In certain of such acquisitions, the Company has granted
specific remedies to the sellers in the event that the registration statement
covering the relevant shares is not declared effective by the Securities and
Exchange Commission within an agreed-upon period of time, including the right to
require the Company to repurchase the shares issued to such seller. During 1997,

5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
Company entered into an agreement to set the purchase price per common share
related to certain shares covered by a repurchase agreement to the then current
market price in exchange for additional time to obtain registration of such
shares. The increased amount of such repurchase obligation of $1,696,000 was
charged to retained earnings and shown as an increase in the Common Stock
subject to redemption of the Consolidated Balance Sheet. As of September 30,
1998 and December 31, 1997, the Company had reflected $4,045,000 and $9,734,000,
respectively, of Common Stock subject to redemption on its Consolidated Balance
Sheet related to shares that the Company may be required to repurchase. During
the first nine months ended September 30, 1998, the Company paid $4,775,000 to
sellers who exercised their rights to have shares of Common Stock repurchased.
The Company expects to pay an additional $4,045,000 during the remainder of
1998.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay to the sellers (in
additional shares and/or cash) an amount equal to the shortfall in the value of
the issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement (referred
to as "Price Protection"). Any such Price Protection payments will be charged to
stockholders' equity. During October 1998, the Company issued 590,147 shares
related to certain Price Protection obligations and expects to pay an additional
$1,659,000 in cash related to Price Protection obligations, excluding Price
Protection obligations related to the shares which have repurchase obligations,
referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differ for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both. Although the Company has the option,
in certain cases, to pay certain of such amounts in shares of Common Stock,
payment of significant cash funds to sellers in the event such earnout
provisions are triggered could have a material adverse effect on the Company's
cash flow and financial condition. In addition, the Company may be required to
finance all or a portion of any such cash payments from third-party sources. No
assurance can be given that such capital will be available on terms acceptable
to the Company. In addition, the issuance by the Company of shares of Common
Stock in payment of any such owed amounts could be dilutive to the Company's
stockholders. Contingent consideration associated with acquisitions is recorded
as additional purchase price when resolved.
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement, dated July 21, 1997, and the Registration Rights Agreement dated July
21, 1997, as amended, between the Company and RGC International, LDC ("RGC")
(hereinafter referred to as the "RGC Agreements"), the Company issued 18,000
shares of Series C Convertible Preferred Stock, $1,000 stated value per share
(the "Series C Preferred Stock") to RGC. Under the RGC Agreements, the Company
was required to use its best efforts to include the shares of Common Stock
issuable upon conversion of the Series C Preferred Stock (the "RGC Conversion
Shares") in an effective Registration Statement not later than October 1997. As
 
                                       14

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
 
5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
amended, the RGC Agreements provided for monthly penalties through July 23, 1998
("RGC Registration Penalties") in the event that the Company failed to register
the Conversion Shares prior to certain dates.
 
    Each share of the Series C Preferred Stock is convertible into such number
of shares of Common Stock as is determined by dividing the stated value ($1,000)
of each share of Series C Preferred Stock plus 3% per annum from the closing
date to the conversion date by the lesser of (i) $62.10 or (ii) the average of
the daily closing bid prices for the Common Stock for the (5) five consecutive
trading days ending five (5) trading days prior to the date of conversion. On
June 18, 1998, 2,500 shares of Series C Preferred Stock were converted into
373,000 shares of Common Stock. Accordingly, as of September 30, 1998, 15,500
shares of the Company's Series C Preferred Stock were issued and outstanding. On
November 10, 1998, an additional 600 shares of Series C Preferred Stock were
converted into 342,000 shares of Common Stock.
 
    As a result of the Company's failure to register the RGC Conversion Shares
until October 1, 1998, the Company: (i) issued warrants to RGC to acquire
389,000 shares of Common Stock at an exercise prices ranging from $34.86 to
$38.85 per share, subject to reset in November 1998 (such warrants having an
estimated value, for accounting purposes, of $3,245,000); and (ii) issued
interest bearing promissory notes (the "RGC Penalty Notes") in the aggregate
principal amount of $2,450,000 due October 15, 1998. The principal amount of and
interest accrued on the RGC Penalty Notes may be converted, at the option of the
Company or RGC in certain circumstances, into additional shares of Series C
Preferred Stock or Common Stock. From and after July 23, 1998, pursuant to an
amendment to the RGC Agreements entered into in June 1998, the Company is no
longer subject to monthly penalties for failure to register the RGC Conversion
Shares, except that RGC may presently elect a one-time penalty of $1,550,000
(the "September 1998 Penalty") because the RGC Conversion Shares were not
registered by September 15, 1998. The September 1998 Penalty, if it shall become
due by election of RGC, shall be payable, at the option of RGC, in cash or
additional shares of Common Stock.
 
    On October 15, 1998, the Company did not pay RGC the $2,450,000 that was
then due and payable under the RGC Penalty Notes. Additional, as discussed
above, RGC may demand the September 1998 Penalty of $1,550,000. The Company and
RGC are currently in discussions regarding the restructuring of the Penalty
Notes and the September 1998 Penalty, but there can be no assurance that the
Company will be successful in restructuring the Penalty Notes on terms favorable
to the Company or its shareholders. Purchasers of Common Stock could therefore
experience substantial dilution upon additional conversion of the Series C
Preferred Stock, any conversion of RGC Penalty Notes into Common Stock and the
impact of the exercise of warrants held by RGC. The shares of Series C Preferred
Stock are not registered and may be sold only with the express written consent
of the Company and if registered under the Act or sold in accordance with an
applicable exemption from registration, such as Rule 144.
 
6. DISCONTINUED OPERATIONS
 
    On August 18, 1998, the Company sold the stock of StarMed to RehabCare
Group, Inc. for gross proceeds of $33,000,000 (the "StarMed Sale"). Due to the
StarMed Sale, the results of operations of StarMed are herein reflected in the
Company's Consolidated Statements of Operations as discontinued operations.
 
    Net cash proceeds from the StarMed Sale were used as follows: (i)
$13,786,000 was used to retire StarMed's outstanding third-party debt (in
accordance with the terms of sale) (ii) $2,000,000 was placed in escrow to be
available, for a specified period of time, to fund indemnification obligations
that may be

incurred by the Company (part or all of this amount may be payable to the
Company over time), (iii) an additional $2,000,000 was applied as a partial
repayment of the Company's $78,000,000 of Senior Notes, and (iv) $2,186,000 was
used to fund cash costs associated with the sale. The remaining net proceeds of
$13,028,000 increased the Company's consolidated cash balances. For accounting
purposes, an after-tax gain on sale of $3,905,000 was reported in the third
quarter of 1998.

(a) 1998 amounts reflect results through August 15, 1998, the date of sale of
    StarMed.
 
    In June 1998, an individual filed a complaint against the Company, StarMed,
Wesley Medical Resources, Inc., a subsidiary of the Company ("Wesley"), and
certain officers and directors of the Company in the United States District
Court for the Northern District of California. The complaint, among other
things, alleges that the defendants omitted and/or misrepresented material
information in the Company's public filings and that they concealed or failed to
disclose material adverse information about the Company in connection with the
sale of Wesley to the Company by the plaintiff. The plaintiff seeks damages in
the amount of $4.25 million or, alternatively, recission of the sale of Wesley.
The Company believes that it has meritorious defenses to the claims asserted by
plaintiff, and intends to defend itself vigorously. In July 1998, the Company
and the named defendants filed a motion to dismiss the plaintiff's complaint on
numerous grounds. On October 7, 1998, the action was transferred for pre-trial
proceedings to the United States District Court of New Jersey. The legal
proceeding described above is in its preliminary stages. Although the Company
believes it has meritorious defenses to all claims against it, the Company is
unable to predict with any certainty the ultimate outcome of such proceeding.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
RESULTS OF CONTINUING OPERATIONS
 
REVENUE RECOGNITION
 
    At each of the Company's diagnostic imaging centers, all medical services
are performed exclusively by physician groups (the "Physician Group" or the
"Interpreting Physician"), generally consisting of radiologists with whom the
Company has entered into independent contractor agreements. Pursuant to these
agreements, the Company has agreed to provide equipment, premises, comprehensive
management and administration, including responsibility for billing and
collection of receivables, and technical imaging services to the Interpreting
Physician.
 
    Net service revenues for the Diagnostic Imaging segment are reported, when
earned, at their estimated net realizable amounts from patients, third party
payors and others for services rendered at contractually established billing
rates which generally are at a discount from gross billing rates. Known and
estimated differences between contractually established billing rates and gross
billing rates (referred to as "contractual allowances") are recognized in the
determination of net service revenues at the time services are rendered. Subject
to the foregoing, the Company's diagnostic imaging centers recognize revenue
under one of the three following types of agreements with Interpreting
Physicians:
 
    Type I--The Company receives a technical fee for each diagnostic imaging
procedure performed at a center, the amount of which is dependent upon the type
of procedure performed. The fee included in revenues is net of contractual
allowances. The Company and the Interpreting Physician proportionally share in
any losses due to uncollectible amounts from patients and third party payors,
and the Company has established reserves for its share of the estimated
uncollectible amount. Type I net service revenues for the three months and nine
months ended September 30, 1998 were $23,035,000 and $73,318,000, respectively,
or 55% and 54% of diagnostic imaging revenues, respectively.
 
    Type II--The Company bills patients and third party payors directly for
services provided and pays the Interpreting Physicians either (i) a fixed
percentage of fees collected at the center, or (ii) a contractually fixed amount
based upon the specific diagnostic imaging procedures performed. Revenues are
recorded net of contractual allowances and the Company accrues the Interpreting
Physician fee as an expense on the Consolidated Statements of Operations. The
Company bears the risk of loss due to uncollectible amounts from patients and
third party payors, and the Company has established reserves for the estimated
uncollectible amount. Type II net service revenues for the three months and nine
months ended September 30, 1998 were $15,818,000 and $51,718,000, respectively,
or 37% and 38% of diagnostic imaging revenues, respectively.
 
    Type III--The Company receives from an affiliated physician association a
fee for the use of the premises, a fee per procedure for acting as billing and
collection agent and a fee for administrative and technical services performed
at the centers. The affiliated physicians association contracts with and pays
directly the Interpreting Physicians. The Company's fee, net of an allowance
based upon the affiliated physician association's ability to pay after the
association has fulfilled its obligations (i.e., estimated future net
collections from patients and third party payors less facility lease expense and
Interpreting Physicians fees), constitutes the Company's net service revenues.
Since the Company's net service revenues are dependent upon the amount
ultimately realized from patient and third party receivables, the Company's
revenue and receivables have been reduced by an estimate of patient and third
party payor contractual allowances, as well as an estimated provision for
uncollectible amounts from patients and third party payors. Type III net service
revenues for the three months and nine months ended September 30, 1998 were
$3,394,000 and $10,141,000, respectively, or 8% of diagnostic imaging revenues.
 
    Revenues derived from Medicare and Medicaid are subject to audit by such
agencies. The Company is not aware of any pending audits.
 
                                       18
<PAGE>
    The fees received or retained by the Company under the three types of
agreements with Interpreting Physicians described above, expressed as a
percentage of gross billings net of contractual allowances for the imaging
services provided, range from 78% to 93% for the Type I agreements, 80% to 93%
for the Type II agreements and 80% to 89% for the Type III agreements. These
agreements generally have terms ranging from one to ten years.
 
QUARTER ENDED SEPTEMBER 30, 1998 COMPARED TO THE QUARTER ENDED SEPTEMBER 30,
  1997
 
    For the quarter ended September 30, 1998, total Company net service revenues
were $44,176,000 versus $42,022,000 for the quarter ended September 30, 1997, an
increase of $2,154,000 or 5%.
 
    The increase in net service revenues is due primarily to the impact of 1997
acquisitions made after June 30, 1997, which contributed $7,226,000 of the
increase. Revenues at imaging centers that have been operated by the Company
since July 1, 1997 decreased $5,072,000 or 13%, to $33,106,000 for the quarter
ended September 30, 1998 from $38,178,000 for the same period in 1997, primarily
as a result of higher contractual allowances within comparable payor groups,
lower total procedure volumes, a payor mix change away from person injury claim
business toward more managed care business, and a modality mix change toward
lower priced procedures.
 
    Contractual allowances are largely dependent upon reimbursement rates from
third party payors, including Medicare, Medicaid and managed care providers.
Management believes that it is likely that the Company's overall reimbursement
rates will gradually decline for some period of time, due to factors such as the
expansion of managed care organizations and continued national healthcare reform
efforts. The Company intends to attempt to mitigate the impact of any decline in
reimbursement rates by decreasing costs and increasing referral volumes. If the
rate of decline in reimbursement rates were to increase materially, or if the
Company is unsuccessful in reducing its costs or increasing its volumes, the
Company's results could be materially and adversely affected.
 
    Diagnostic Imaging revenues derived from personal injury claims, mainly
involving automobile accidents, represented approximately 14% of Diagnostic
Imaging business net service revenues for the quarter ended September 30, 1998.
Automobile insurance carriers generally pay the non-deductible non-co-pay
portion of the charge, with the remaining balance payable by the individual. The
timing of collection from the individual is partially dependent upon the outcome
and timing of any settlement or judgment of the injury claim. Accordingly, such
receivables typically require a longer period of time to collect compared to the
Company's other receivables, and in the experience of the Company incur a higher
bad debt expense. In addition, a number of states have enacted legislation that
is intended to curtail auto insurance spending on personal injury claims.
Although the Company recently has intentionally shifted away from personal
injury claim business due to its high bad debt rate and long collection cycle,
if such business were to further materially decline either as a result of poorer
than expected future collections performance or because of such legislation, the
Company's results could be materially adversely affected.
 
    Costs of services for the three months ended September 30, 1998 were
$27,797,000 compared to $21,222,000 for the three months ended September 30,
1997, an increase of $6,575,000 or 31%. This increase was due to the inclusion
of operating costs of $4,318,000 related to centers acquired after July 1, 1997.
Costs of services at imaging centers that have been operated by the Company
since July 1, 1997 increased $2,257,000, to $21,968,000 for the quarter ended
September 30, 1998 from $19,711,000 for the same period in 1997, primarily as a
result of higher equipment maintenance, independent contractor and payroll costs
in the third quarter of 1998.
 
    The provision for uncollectible accounts receivable for the quarter ended
September 30, 1998 was $3,377,000, or 8% of related net service revenues,
compared to the third quarter 1997 provision of $2,042,000, or 5% of related net
service revenues. The increase in the provision for uncollectible accounts
receivable, as a percentage of net service revenues, was due to an increase in
the estimated rate of bad debts. Personal injury claim revenues have declined
during 1998 as a percentage of total net service
 
                                       19
<PAGE>
revenues, which should result in a reduction in the rate of bad debts over time.
However, the Company has continued to accrue for estimated bad debts at the rate
of 8% of diagnostic imaging net revenues throughout the first nine months of
1998 since diagnostic imaging receivables remain somewhat higher than the level
at the beginning of year. Cash collections have improved during the third
quarter of 1998 relative to early 1998 collections performance and, provided the
Company continues to improve its collections, the Company expects to accrue bad
debts at a lower rate in the future.
 
    Depreciation and amortization expense for the third quarter of 1998 was
$6,109,000, compared to $5,488,000 for the third quarter of 1997, or an increase
of $621,000. The increase was due primarily to higher equipment depreciation
resulting from 1997 acquisitions and increased goodwill amortization.
 
    Gross profit margins, which represent net service revenue less center costs
as a percent of net revenue, decreased for the quarter ended September 30, 1998
to 11% from 29% for the quarter ended September 30, 1997 due primarily to the
reasons described above.
 
    Corporate general and administrative expense for the three months ended
September 30, 1998 was $2,979,000, an increase of $30,000 from the $2,949,000
recorded for the three months ended September 30, 1997.
 
    In July 1998, the Company completed a review of under-performing centers and
determined that it would sell or close eight imaging centers during the third
and fourth quarters of 1998. In most cases, the Company decided to sell or close
these centers due to general competitive pressures and because of their close
proximity to other imaging centers of the Company which have more advanced
imaging equipment. During the three months ended September 30, 1998, the Company
recorded unusual charges attributable to center closings of $3,489,000,
consisting of (i) $1,602,000 for the estimated costs to exit equipment lease and
maintenance agreements and facility lease agreements, (ii) $1,481,000 for the
write-off of fixed assets, goodwill and other intangibles and other assets, and
(iii) $406,000 for estimated equipment removal, facility restoration and related
costs.
 
    In addition, other unusual charges were recorded during the three months
ended September 30, 1998 of $890,000, consisting of (i) $380,000 for
professional fees attributable to obtaining the waiver and amendment under the
Company's Senior Note obligations, (ii) $360,000 for penalties associated with
the delay in the effectiveness of the Company's Registration Statement (which
has now become effective) and (iii) $150,000 for defense costs relating to
shareholder and employee lawsuits.
 
    The Company could incur a substantial additional amount of unusual charges
during the remainder of 1998 depending upon the outcome of shareholder and
employee lawsuits and current negotiations with the holders of the Series C
Preferred Stock regarding additional penalties associated with the failure to
timely register the Company's Common Stock.
 
    Net interest expense for the three months ended September 30, 1998 was
$3,484,000 as compared to $2,543,000 for the three months ended September 30,
1997, an increase of $941,000. This increase was primarily attributable to debt
assumed in connection with the Company's 1997 acquisitions and borrowings under
notes payable and lines of credit.
 
    The Company's income for the quarter ended September 30, 1998 was decreased
by $176,000 attributable to minority interests, as compared to an increase in
the Company's income of $306,000 for the quarter ended September 30, 1997.
 
    The provision for income taxes for the three months ended September 30, 1998
decreased to $160,000 as compared to $3,014,000 for the comparable period last
year. The provision for income taxes for the three months ended September 30,
1998 consists entirely of estimated state income taxes. During the third quarter
of 1998, a benefit for income taxes has not been recorded due to the uncertainty
regarding the recognition of the full amount of the Company's deferred tax
assets.
 
                                       20
<PAGE>
    The Company's net loss from continuing operations for the quarter ended
September 30, 1998 was $6,196,000 compared to net income from continuing
operations for the quarter ended September 30, 1997 of $3,909,000.
 
    The net loss applicable to common stockholders (used in computing loss per
common share) in the third quarter of 1998 includes charges of $116,000 as a
result of the accretion of the Company's preferred stock.
 
NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
  1997
 
    For the nine months ended September 30, 1998, total Company's net service
revenues were $137,824,000 versus $106,740,000 for the nine months ended
September 30, 1997, an increase of $31,084,000 or 29%.
 
    The increase in net service revenues is due primarily to the impact of 1997
acquisitions, which contributed $42,376,000 of the increase. Revenues at imaging
centers that have been operated by the Company for all of 1997 decreased
$11,292,000 or 16%, to $60,555,000 for the nine months ended September 30, 1998
from $71,847,000 for the same period in 1997, primarily as a result of higher
contractual allowances within comparable payor groups, lower total procedure
volumes, a payor mix change away from person injury claim business toward more
managed care business, and a modality mix change toward lower priced procedures.
 
    Costs of Services for the nine months ended September 30, 1998 were
$86,129,000 compared to $55,839,000 for the nine months ended September 30,
1997, an increase of $30,290,000 or 54%. This increase was due to the inclusion
of operating costs of $24,145,000 related to centers acquired during 1997. Costs
of services at imaging centers that have been operated by the Company for all of
1997 increased $6,145,000, to $42,657,000 for the nine months ended September
30, 1998 from $36,512,000 for the nine months ended September 30, 1997,
primarily as a result of higher equipment maintenance and payroll costs in the
nine months ended September 30, 1998.
 
    The provision for uncollectible accounts receivable for the nine months
ended September 30, 1998 was $10,684,000, or 8% of related net service revenues,
compared to the nine months ended September 30, 1997 provision of $5,795,000, or
5% of related net service revenues. The increase in the provision for
uncollectible accounts receivable, as a percentage of net service revenues, was
due to an increase in the estimated rate of bad debts, as described above.
 
    Depreciation and amortization expense for the first nine months of 1998 was
$18,744,000 compared to $12,567,000 for the first nine months of 1997, or an
increase of $6,177,000, due primarily to higher equipment depreciation resulting
from 1997 acquisitions and increased goodwill amortization.
 
    Gross profit margins, which represent net service revenue less center costs
as a percent of net revenue, decreased for the first nine months of 1998 to 13%
from 29% for the first nine months of 1997 due primarily to the reasons
described above.
 
    Corporate general and administrative expense for the nine months ended
September 30, 1998 was $8,794,000, an increase of $2,239,000 from the $6,555,000
recorded for the nine months ended September 30, 1997. This increase was
primarily due to higher payroll and related costs as a result of the expanded
business development activities and the resulting growth experienced during
1997.
 
    Results for the nine months ended September 30, 1998 and 1997 include non-
cash charges of $304,000 and $2,305,000, respectively, for compensation expense
resulting from stock options granted in 1996 and early 1997 that were approved
by the Company's stockholders in May 1997. Such compensation expense represents
the difference between the exercise price of the options and the market price of
the Company Common Stock on the date of plan approval, attributable to vested
shares.

    During the nine months ended September 30, 1998, the Company recorded
unusual charges attributable to center closings of $3,489,000, as described
above, and other unusual charges of $6,290,000, including the $890,000 recorded
during the third quarter of 1998. The other unusual charges consist of (i)
$3,827,000 ($1,194,000 of which was a non-cash charge related to the issuance of
117,000 common stock warrants) for penalties associated with the delay in the
effectiveness the Company's Registration Statement (which has now become
effective), (ii) $863,000 for defense costs relating to shareholder and employee
lawsuits, (iii) $883,000 for costs associated with the investigation of related
party transactions which was concluded in April 1998, (iv) $380,000 for
professional fees attributable to obtaining the waiver and amendment under the
Company's Senior Note obligations and (v) $337,000 for management termination
benefits and related costs.
 
    Net interest expense for the nine months ended September 30, 1998 was
$10,396,000 as compared to $5,276,000 for the nine months ended September 30,
1997, an increase of $5,120,000. This increase was primarily attributable to
higher outstanding debt, including the issuance of $78,000,000 of Senior Notes
during 1997 and notes payable and capital lease obligations assumed in
connection with the Company's 1997 acquisitions.
 
    The Company's income for the nine months ended September 30, 1998 was
decreased by $819,000 attributable to minority interests, as compared to an
increase in the Company's income of $499,000 for the nine months ended September
30, 1997.
 
    The provision for income taxes for the nine months ended September 30, 1998
decreased to $461,000 as compared to $7,093,000 for the comparable period last
year. The provision for income taxes for the nine months ended September 30,
1998 consists entirely of estimated state income taxes. During the first nine
months of 1998, a benefit for income taxes has not been recorded due to the
uncertainty regarding the recognition of the full amount of the Company's
deferred tax assets.
 
    The Company's net loss from continuing operations for the nine months ended
September 30, 1998 was $13,126,000 compared to net income from continuing
operations for the nine months ended September 30, 1997 of $9,899,000.
 
    The net loss applicable to common stockholders (used in computing loss per
common share) in the first nine months of 1998 includes charges of $390,000 as a
result of the accretion of the Company's preferred stock.
 
RESULTS OF DISCONTINUED OPERATIONS
 
PERIOD FROM JANUARY 1, 1998 TO AUGUST 15, 1998 COMPARED TO NINE MONTHS ENDED
  SEPTEMBER 30, 1997
 
    Net service revenues for StarMed increased to $51,087,000 for the period
ended August 15, 1998 (which represents seven and one-half months) from
$41,484,000 for the nine months ended September 30, 1997, an increase of
$9,603,000. This increase was primarily related to internal growth in the
staffing business, consisting primarily of the opening of new Per Diem division
offices.
 
    Operating costs for StarMed for the period ended August 15, 1998 were
$40,568,000 compared to $33,458,000 for the nine months ended September 30,
1997, an increase of $7,110,000. This increase was primarily related to internal
growth in the staffing business.
 
    Net earnings related to StarMed increased to $1,806,000 for the period ended
August 15, 1998 from $773,000 for the nine months ended September 30, 1997.
 
STARMED SALE
 
    On August 18, 1998, the Company sold the stock of StarMed to RehabCare
Group, Inc. for gross proceeds of $33,000,000. Due to the StarMed Sale, the
results of operations of StarMed are herein reflected in the Company's
Consolidated Statements of Operations as discontinued operations.
 
                                       22
<PAGE>
    Net cash proceeds from the StarMed Sale were used as follows: (i)
$13,786,000 was used to retire StarMed's outstanding third-party debt (in
accordance with the terms of sale) (ii) $2,000,000 was placed in escrow to be
available, for a specified period of time, to fund indemnification obligations
that may be incurred by the Company (part or all of this amount may be payable
to the Company over time), (iii) an additional $2,000,000 was applied as a
partial repayment of the Company's $78,000,000 of Senior Notes, and (iv)
$2,186,000 was used to fund cash costs associated with the sale. The remaining
net proceeds of $13,028,000 increased the Company's consolidated cash balances.
For accounting purposes, an after-tax gain on sale of $3,905,000 was reported in
the third quarter of 1998.
 
LIQUIDITY AND CAPITAL RESOURCES
 
CASH FLOWS
 
    During the nine months ended September 30, 1998, the Company's primary
source of cash flow was proceeds from the sale of the Company's StarMed Staffing
subsidiary of $28,814,000. The primary use of cash was the repayment of interest
bearing debt, including $13,786,000 of the debt of StarMed Staffing (in
accordance with the terms of sale) and other net reductions in debt of
$11,957,000. The Company also used cash of $4,775,000 for the repurchase of
Common Stock subject to redemption as a result of the exercise of puts provided
by the Company in connection with 1997 acquisitions. Operating activities
provided cash of $1,154,000 during the nine months ended September 30, 1998.
Cash flow from operating activities was adversely effected by an increase of
$8,211,000 in accounts receivable, net of allowance for bad debts (such amount
includes an increase of $2,540,000 related to StarMed prior to its sale). The
increase in accounts receivable is the result of difficulties experienced in
integrating the billing and collection systems of the centers acquired during
1997. By July of 1998, the Company completed the planned conversion of over 77%
of its centers to the Company's proprietary radiology information system, ICIS,
and commenced a restructuring of its collection efforts for the purpose of
ultimately consolidating all collections activities into a few regional
collection offices. The restructuring is in response to the need to improve
overall collection results and controls. The Company expects that these efforts
will result in an improved collection rate of accounts receivable and cash
flows. During the third quarter of 1998, cash collections improved relative to
early 1998 collections performance and outstanding diagnostic imaging net
accounts receivable declined $1,700,000 from $59,493,000 at June 30, 1998 to
$57,793,000 at September 30, 1998.
 
    During the nine months ended September 30, 1997, the Company's primary
source of cash flow was from financing activities, including net proceeds from
the issuance of the Senior Notes of $77,113,000 and Series C Preferred Stock of
$16,965,000. The primary use of cash was to fund acquisitions that totaled
$56,132,000 and to fund the repayment of certain notes and capital lease
obligations of $27,025,000. Operating activities resulted in a net use of cash
of $3,318,000 during the first nine months of 1997, primarily as a result of an
increase in net accounts receivable of $22,211,000.
 
    The Company has never declared a dividend on its Common Stock and under the
Company's Senior Note agreement, the payments of such dividends is not
permitted.
 
SENIOR NOTE DEFAULTS
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company was in default of certain financial covenants
under its $78,000,000 of Senior Notes. The financial covenant defaults under the
Senior Note agreements entitled the lenders to exercise certain remedies
including acceleration of repayment. In addition, certain medical equipment
notes, and operating and capital leases of the Company (the "Cross-Default
Debt"), contain provisions which allow the creditors or lessors to accelerate
their debt or terminate their leases and seek certain other remedies if the
Company is in default under the terms of agreements such as the Senior Notes.
 
                                       23
<PAGE>
    In the event that the Senior Note lenders or the holders of the Cross
Default Debt elected to exercise their right to accelerate the obligations under
the Senior Notes or the other loans and leases, such acceleration would have had
a material adverse effect on the Company, its operations and its financial
condition. Furthermore, if such obligations were accelerated, in whole or in
part, there could be no assurance that the Company would have been successful in
identifying or consummating financing necessary to satisfy the obligations which
would have become immediately due and payable. As a result of the uncertainty
related to the defaults and corresponding remedies described above, the Senior
Notes and the Cross Default Debt were shown as current liabilities on the
Company's Consolidated Balance Sheets at December 31, 1997. As a result of these
matters, as well as other issues, there was substantial doubt about the
Company's ability to continue as a going concern. The report of the Company's
independent auditors, Ernst & Young LLP, on the consolidated financial
statements of the Company for the year ended December 31, 1997 contains an
explanatory paragraph with respect to these issues. The December 31, 1997
financial statements did not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    In October 1998, management reached an agreement with the Senior Note
lenders with respect to a waiver of all existing covenant defaults and a
modification of the financial covenants applicable over the remaining term of
the Senior Notes. In consideration for this waiver and amendment, the Company
has agreed to increase the effective blended interest rate on the Senior Notes
from 7.87% to 9.00%, and issued to the Senior Note lenders warrants to acquire
375,000 shares of the Company's Common Stock at an exercise price of $7.67 per
common share. The warrants had an estimated value of $503,000 which will be
recorded as deferred financing expense and amortized over the remaining term of
the Senior Notes. In addition, the Company prepaid $2,000,000 of principal
outstanding on the Senior Notes (without premium) and paid a fee to the Senior
Note lenders of $500,000. As a result of the execution of the waiver and
amendment with respect to the Senior Notes, the Senior Notes and the Cross
Default Debt are no longer in default and have been shown as long-term debt in
the September 30, 1998 Consolidated Balance Sheet.
 
WORKING CAPITAL
 
    The Company has a working capital surplus of $40,233,000 at September 30,
1998 compared to a working capital deficit of $58,174,000 at December 31, 1997.
The improvement in working capital is due primarily to the reclassification of
the Senior Notes and Cross Default Debt as long-term debt in the September 30,
1998 Consolidated Balance Sheet.
 
OTHER OBLIGATIONS OF THE COMPANY
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration, the Company
granted rights to have such shares registered for resale pursuant to the federal
securities laws. In certain of such acquisitions, the Company has granted
specific remedies to the sellers in the event that the registration statement
covering the relevant shares is not declared effective by the Securities and
Exchange Commission within an agreed-upon period of time, including the right to
require the Company to repurchase the shares issued to such seller. During 1997,
the Company entered into an agreement to set the purchase price per common share
related to certain shares covered by a repurchase agreement to the then current
market price in exchange for additional time to obtain registration of such
shares. The increased amount of such repurchase obligation of $1,696,000 was
charged to retained earnings and shown as an increase in the Common Stock
subject to redemption of the Consolidated Balance Sheet. As of September 30,
1998 and December 31, 1997, the Company had reflected $4,045,000 and $9,734,000,
respectively, of Common Stock subject to redemption on its Consolidated Balance
Sheet related to shares that the Company may be required to repurchase. During
the first nine months ended September 30, 1998, the Company paid $4,775,000 to
sellers who exercised their rights
 
                                       24
<PAGE>
to have shares of Common Stock repurchased. The Company expects to pay an
additional $4,045,000 during the remainder of 1998.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay to the sellers (in
additional shares and/or cash) an amount equal to the shortfall in the value of
the issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement (referred
to as "Price Protection"). Any such Price Protection payments will be charged to
stockholders' equity. During October 1998, the Company issued 590,147 shares
related to certain Price Protection obligations and expects to pay an additional
$1,659,000 in cash related to Price Protection obligations, excluding Price
Protection obligations related to the shares which have repurchase obligations,
referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differ for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both. Although the Company has the option,
in certain cases, to pay certain of such amounts in shares of Common Stock,
payment of significant cash funds to sellers in the event such earnout
provisions are triggered could have a material adverse effect on the Company's
cash flow and financial condition. In addition, the Company may be required to
finance all or a portion of any such cash payments from third-party sources. No
assurance can be given that such capital will be available on terms acceptable
to the Company. In addition, the issuance by the Company of shares of Common
Stock in payment of any such owed amounts could be dilutive to the Company's
stockholders. Contingent consideration associated with acquisitions is recorded
as additional purchase price when resolved.
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement, dated July 21, 1997, and the Registration Rights Agreement dated July
21, 1997, as amended, between the Company and RGC International, LDC ("RGC")
(hereinafter referred to as the "RGC Agreements"), the Company issued 18,000
shares of Series C Convertible Preferred Stock, $1,000 stated value per share
(the "Series C Preferred Stock") to RGC. Under the RGC Agreements, the Company
was required to use its best efforts to include the shares of Common Stock
issuable upon conversion of the Series C Preferred Stock (the "RGC Conversion
Shares") in an effective Registration Statement not later than October 1997. As
amended, the RGC Agreements provided for monthly penalties through July 23, 1998
("RGC Registration Penalties") in the event that the Company failed to register
the Conversion Shares prior to certain dates.
 
    Each share of the Series C Preferred Stock is convertible into such number
of shares of Common Stock as is determined by dividing the stated value ($1,000)
of each share of Series C Preferred Stock plus 3% per annum from the closing
date to the conversion date by the lesser of (i) $62.10 or (ii) the average of
the daily closing bid prices for the Common Stock for the (5) five consecutive
trading days ending five (5) trading days prior to the date of conversion. On
June 18, 1998, 2,500 shares of Series C Preferred Stock were converted into
373,000 shares of Common Stock. Accordingly, as of September 30, 1998, 15,500
shares of the Company's Series C Preferred Stock were issued and outstanding. On
November 10, 1998, an additional 600 shares of Series C Preferred Stock were
converted into 342,000 shares of Common Stock.
 
    As a result of the Company's failure to register the RGC Conversion Shares
until October 1, 1998, the Company: (i) issued warrants to RGC to acquire
389,000 shares of Common Stock at an exercise prices ranging from $34.86 to
$38.85 per share, subject to reset in November 1998 (such warrants having an
 
                                       25
<PAGE>
estimated value, for accounting purposes, of $3,245,000); and (ii) issued
interest bearing promissory notes (the "RGC Penalty Notes") in the aggregate
principal amount of $2,450,000 due October 15, 1998. The principal amount of and
interest accrued on the RGC Penalty Notes may be converted, at the option of the
Company or RGC in certain circumstances, into additional shares of Series C
Preferred Stock or Common Stock. From and after July 23, 1998, pursuant to an
amendment to the RGC Agreements entered into in June 1998, the Company is no
longer subject to monthly penalties for failure to register the RGC Conversion
Shares, except that RGC may presently elect a one-time penalty of $1,550,000
(the "September 1998 Penalty") because the RGC Conversion Shares were not
registered by September 15, 1998. The September 1998 Penalty, if it shall become
due by election of RGC, shall be payable, at the option of RGC, in cash or
additional shares of Common Stock.
 
    On October 15, 1998, the Company did not pay RGC the $2,450,000 that was
then due and payable under the RGC Penalty Notes. Additional, as discussed
above, RGC may demand the September 1998 Penalty of $1,550,000. The Company and
RGC are currently in discussions regarding the restructuring of the Penalty
Notes and the September 1998 Penalty, but there can be no assurance that the
Company will be successful in restructuring the Penalty Notes on terms favorable
to the Company or its shareholders. Purchasers of Common Stock could therefore
experience substantial dilution upon additional conversion of the Series C
Preferred Stock, any conversion of RGC Penalty Notes into Common Stock and the
impact of the exercise of warrants held by RGC. The shares of Series C Preferred
Stock are not registered and may be sold only with the express written consent
of the Company and if registered under the Act or sold in accordance with an
applicable exemption from registration, such as Rule 144.
 
    In addition to matters discussed above, the Company is subject to litigation
that may require additional future cash outlays.
 
FINANCIAL RESOURCES
 
    During 1997, the Company incurred substantial debt in connection with
acquisitions of imaging centers. As of September 30, 1998, the Company's debt,
including capitalized lease obligations, totaled $133,537,000. The Company does
not expect to incur significant additional debt in the near future and expects
to rely on its existing cash balances of $16,409,000 at September 30, 1998 and
its ability to enter into operating leases to fund expansions and equipment
replacement at its centers. As a result of improvements in the Company's billing
and collection systems, the Company expects its cash flow from operations,
including improved collections of accounts receivable, to increase from the
level achieved in the nine months ended September 30, 1998. Management believes
that the positive cash flow from operations and the Company's existing cash
balances will provide it with sufficient funds available to finance its needs in
the near term.
 
COMMON STOCK
 
    In July 1998, the Company's shareholders approved a reverse stock split of
the Company's outstanding shares of Common Stock. As a result of the reverse
stock split, each three outstanding shares of Common Stock were automatically
converted into one share of new Common Stock. The share data included in this
Form 10-Q have been adjusted to reflect the impact of the reverse stock split.
 
    The Company has been notified by NASDAQ that it is being reviewed for
continued listing on NASDAQ's National Market System due to its failure to
continue to meet the $5.00 minimum bid price requirement. The Company has until
January 15, 1999 to satisfy the listing requirements. In the event it is unable
to meet the requirements for continued listing on the National Market System,
the Company will attempt to move its listing to NASDAQ's SmallCap Market. No
assurance can be given that the Company will be successful in that regard.
 
                                       26
<PAGE>
SEASONALITY AND INFLATION
 
    The Company believes that its business is only moderately affected by
seasonality. The third quarter is typically the slowest quarter of the year
because the months of July and August are the principal vacation months of the
year. The impact of inflation and changing prices on the Company has been
primarily limited to salary, medical and film supplies and rent increases and
has not been material to date to the Company's operations. Notwithstanding the
foregoing, general inflation trends and continuing reimbursement rate pressures
in the future may cause the Company not to be able to raise the prices for its
diagnostic imaging procedures by an amount sufficient to offset the negative
effects of increasing costs. While the Company has responded to these concerns
in the past by increasing the volume of its business, there can be no assurance
that the Company will be able to increase its volume of business in the future.
These trends, if continued over time, could have a material effect on the
financial results of the Company.
 
IMPACT OF YEAR 2000 ON COMPANY'S COMPUTER SOFTWARE
 
    The computer programming code utilized in the Company's financial, billing
and imaging equipment systems were generally written using two digits rather
than four to define the applicable year. As a result, those computer programs
have time-sensitive software that recognizes a date using 00's as the year 1900
rather than the year 2000. This could cause a system failure or miscalculations
resulting in disruptions of operations, including, among other things, a
temporary inability to process transactions, send invoices or engage in other
normal business activities.
 
    The Company has completed an assessment of its material financial and
billing computer systems. The Company is in the process of upgrading these
systems to be Year 2000 compliant and expects to complete this process by late
1998 or early 1999. The cost to be incurred related to Year 2000 compliance for
these systems is currently not expected to be material.
 
    The Company has initiated a program to determine whether the computer
applications of its significant payors and suppliers will be upgraded in a
timely manner. The Company has also initiated a program to determine whether
embedded applications that control certain medical and other equipment will be
affected. The Company has not yet completed these reviews. The nature of the
Company's business is such that any failure to these types of applications may
have a material adverse effect on its business. If the Company determines that
certain of its suppliers will not be Year 2000 compliant, then the Company will
endeavor to find alternative suppliers; however, there can be no assurance that
the Company will be able to find alternative suppliers.
 
    Because of the many uncertainties associated with Year 2000 compliance
issues, and because the Company's assessment is necessarily based on information
from third party-vendors, payors and suppliers, there can be no assurance that
the Company's assessment is correct or as to the materiality or effect of any
failure of such assessment to be correct. The Company is currently developing
contingency plans to address potential Year 2000 non-compliance both internally
and externally to the Company.
 
    Software sold by the Company's wholly owned subsidiary, Dalcon Technologies,
Inc., is expected to be fully Year 2000 compliant in connection with the annual
upgrade planned for late 1998.
 
DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS
 
    Statements contained in this Report that are not historical facts are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. Investors are cautioned that forward-looking
statements are inherently uncertain. Actual performance and results may differ
materially from that projected or suggested herein due to certain risks and
uncertainties including, without limitation: the ability of the Company to
effectively integrate the operations and information systems of businesses
acquired in 1997 and earlier; the ability of the Company to generate net
positive cash flows from operations; the payment timing and ultimate

accounts receivable) from different payor groups (including Personal Injury
type); the economic impact of involuntary share repurchases and other payments
(including price protection payments and penalty payments) caused by the delay
in the effectiveness of the Company's Registration Statement and by the decline
in the Company's share price; the potential dilution that would result from the
conversion of the Company's Series C Convertible Preferred Stock into common
shares at current share prices; the impact of a changing mix of managed care and
personal injury claim business on contractual allowance provisions, net revenues
and bad debt provisions; the ultimate economic impact of recent litigation
including shareholder and former management lawsuits against the Company and
certain of its Directors; the availability of debt and/or equity capital, on
reasonable terms, to finance operations as needed and to finance growth; and the
effects of federal and state laws and regulations on the Company's business over
time. Additional information concerning certain risks and uncertainties that
could cause actual results to differ materially from that projected or suggested
may be identified from time to time in the Company's Securities and Exchange
Commission filings and the Company's public announcements.

                                  THE COMPANY
 
    The Company specializes in the operation and management of fixed site
outpatient medical diagnostic imaging centers. The Company currently operates 94
outpatient diagnostic imaging centers located in the Northeast (56), Southeast
(24), the Midwest (9) and California (5), and provides network management
services to managed care organizations. The Company has grown rapidly and has
increased the number of diagnostic imaging centers it operates from 39 at
December 31, 1996 to 94 at September 1, 1998. The Company, through its
wholly-owned subsidiary, Dalcon Technologies, Inc. ("Dalcon"), also develops and
markets software products and systems for the diagnostic imaging industry.
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
Divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold the stock of StarMed
to RehabCare Group, Inc. for gross proceeds of $33 million (the "StarMed Sale").
Due to the StarMed Sale, the results of operations of StarMed are herein
reflected in the Company's Consolidated Statements Of Operations as discontinued
operations.
 
    The Company's diagnostic imaging centers provide diagnostic imaging services
to patients referred by physicians in a comfortable, service-oriented
environment located mainly in an outpatient setting. Of the Company's 94
centers, 82 provide magnetic resonance imaging, which accounts for a majority of
the Company's imaging revenues. Many of the Company's centers also provide some
or all of the following services: computerized tomography, ultrasound, nuclear
medicine, general radiology and fluoroscopy and mammography.
 
    At each of the Company's centers, all medical services are performed
exclusively by physician groups (the "Physician Group" or the "Interpreting
Physician"), generally consisting of radiologists, with whom the Company enters
into independent contractor agreements. Pursuant to these agreements, the
Company, among other duties, provides to the Physician Group the diagnostic
imaging facility and equipment, performs all marketing and administrative
functions at the centers and is responsible for the maintenance and servicing of
the equipment and leasehold improvements. The Physician Group is solely
responsible for, and has complete and exclusive control over, all medical and
professional services performed at the centers, including, most importantly, the
interpretation of diagnostic images, as well as the supervision of technicians,
and medical related quality assurance and communications with referring
physicians. Insofar as the Physician Group has complete and exclusive control
over the medical services performed at the centers, including the manner in
which medical services are performed, the assignment of individual physicians to
center duties and the hours that physicians are to be present at the center, the
Company believes that the Interpreting Physicians who perform medical services
at the centers are independent contractors. In addition, Interpreting Physician
Groups which furnish professional services at the centers generally have their
own medical practices and, in most instances, perform medical services at
non-Company related facilities. The Company's employees do not perform
professional medical services at the centers. Consequently, the Company does not
believe that it engages in the practice of medicine in jurisdictions which
prohibit or permit the corporate practice of medicine. The Company performs only
administrative and technical services and does not exercise any control over the
practice of medicine by physicians at the centers or employ physicians to
provide medical services. The Company is aware of three Interpreting Physicians
who own a nominal percentage of three limited partnerships that are managed and
partially owned by the Company.
 
    As part of its administrative responsibilities under the terms of the
Interpreting Physician agreements, the Company is responsible for the
administrative aspects of billing and collection functions at the centers.
Certain third-party payor sources of the Company, such as Medicare, insurance
companies and managed care providers, require that they receive a single or
"global" billing statement for the imaging services provided at the Company's
centers. Consequently, billing is done in the name of the Physician Group
 
                                       3
<PAGE>
because such billings include a medical component. The Physician Group grants a
power of attorney to the Company authorizing the Company to establish bank
accounts using the Physician Group's name related to that center's collection
activities and to access such accounts. In states where permitted by law, such
as Florida, the Company generally renders bills in the center's name. In such
circumstances, the Physician Group has no access to associated collections.
 
    The Company recognizes revenue under its agreements with Interpreting
Physicians in one of three ways: (1) the Company receives a technical fee for
each diagnostic imaging procedure performed at the center, the amount of which
is fixed based upon the type of the procedure performed; (2) the Company pays
the Interpreting Physician Group a fixed percentage of fees collected at the
center or a contractually fixed amount, based upon the specific diagnostic
imaging procedures performed; or, (3) the Company receives from an affiliated
physician association a fee for the use of the premises, a fee per procedure for
acting as billing and collection agent for the affiliated physician association
and for administrative and technical services performed at the centers and the
affiliated physician association pays the Physician Group based upon a
percentage of the cash collected at the center. All of such amounts and the
basis for payments are negotiated between the Physician Group and the Company.
The fees received or retained by the Company under the three types of agreements
with Interpreting Physicians described above, expressed as a percentage of the
gross billings net of contractual allowances for the imaging services provided,
range from 78% to 93% for the agreements described in item (1), 80% to 93% for
the agreements described in item (2) and 80% to 89% for the agreements described
in item (3). The agreements generally have terms ranging from one to ten years.
 
    Since the beginning of 1996, the Company has acquired 90 imaging centers
through 27 acquisitions. When the Company acquires an imaging center, the
Company acquires assets relating to the provision of technical, financial,
administrative and marketing services which support the provision of medical
services performed by the Interpreting Physicians. Such assets typically include
equipment, furnishings, supplies, tradenames of the center, books and records,
contractual rights with respect to leases and other agreements and, in most
instances, accounts receivable. Other than with respect to such accounts
receivable for services performed by the acquired company, the Company does not
acquire any rights with respect to or have any direct relationship, with
patients. Patients have relationships with referral sources who are the primary
or specialty care physicians for such patients. These physicians refer their
patients to diagnostic imaging centers which may include the Company's centers
where Interpreting Physicians, under independent contractor agreements, provide
professional medical services. The Company's acquired imaging centers do not
constitute either a radiology, primary care or specialty care medical practice.
In connection with an acquisition of a center, the Company will generally enter
into an agreement, as described above, with a Physician Group for that physician
group as an independent contractor to perform medical services at the center.
 
    The Company was incorporated in Delaware in August 1990 and has its
principal executive offices at 155 State Street, Hackensack, New Jersey 07601
(telephone no.: (201) 488-6230). Prior to the Company's incorporation, the
Company's operations, which commenced in 1979, were conducted by subsidiary
corporations.

                                  RISK FACTORS
 
    In addition to the other information contained in this Prospectus,
prospective investors should carefully consider the following matters in
evaluating the Company and its business before purchasing the shares of Common
Stock offered hereby.
 
DEFAULTS UNDER LOAN AGREEMENTS
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company is currently in default of certain financial
covenants under the agreements for its $78,000,000 of Senior Notes. The
financial covenant defaults under the Senior Note agreements entitle the lenders
to exercise certain remedies including acceleration of repayment. In addition,
certain medical equipment notes and operating and capital leases of the Company,
aggregating $14,575,000 at June 30, 1998 (the "Cross-Default Debt"), contain
provisions which allow the creditors or lessors to accelerate their debt or
terminate their leases and seek certain other remedies if the Company is in
default under the terms of agreements such as the Senior Notes. In the event
that the Senior Note lenders or the holders of the Cross Default Debt elect to
exercise their right to accelerate the obligations under the Senior Notes or the
other loans and leases, such acceleration would have a material adverse effect
on the Company, its operations and its financial condition. Furthermore, if such
obligations were to be accelerated, in whole or in part, there can be no
assurance that the Company would be successful in identifying or consummating
financing necessary to satisfy the obligations which would become immediately
due and payable. As a result of the uncertainty related to the defaults and
corresponding remedies described above, the Senior Notes and the Cross Default
Debt were shown as current liabilities on the Company's Consolidated Balance
Sheets at June 30, 1998 and December 31, 1997. Accordingly, the Company had a
deficit in working capital of $55,892,000 at June 30, 1998. These matters raise
substantial doubt about the Company's ability to continue as a going concern.
The report of the Company's independent auditors, Ernst & Young LLP, on the
consolidated financial statements of the Company for the year ended December 31,
1997 contains an explanatory paragraph with respect to the issues that raise
substantial doubt about the Company's ability to continue as a going concern
mentioned in Note 2 to the Company's consolidated financial statements. The
financial statements do not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    Management has reached an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications. Under the terms of the agreement in principle, the Senior Note
lenders have agreed to waive all existing covenant defaults and to modify the
financial covenants applicable over the remaining term of the Senior Notes. In
consideration for these waivers and covenant modifications, the Company has
agreed to increase the effective blended interest rate on the Senior Notes from
7.87% to 9.00%, and issue to the Senior Note lenders warrants to acquire 375,000
shares of the Company's Common Stock at an exercise price of $7.67 per common
share. In addition, the Company has agreed to prepay $2,000,000 of principal
outstanding on the Senior Notes (without premium) and to pay a fee to the Senior
Note lenders of $500,000. The agreement in principle is subject to the execution
of definitive documents, which are expected to be completed during September
1998. There can be no assurance, however, that definitive documents effecting
the agreement in principle will be executed.
 
EFFECTS OF LEVERAGE
 
    During 1997, the Company incurred substantial debt in connection with
acquisitions of imaging centers. As of June 30, 1998, the Company's debt,
including capitalized lease obligations, totaled $155,369,000. The Company's
ratio of debt to total capitalization (total debt plus stockholders' equity) was
56% as of June 30, 1998. In addition, the Company is obligated under certain
repurchase obligations, purchase price remedies and earnouts associated with
acquisitions (see "Effects of Grant of Repurchase
 
                                       5
<PAGE>
and Purchase Price Remedies and Earnout Rights to Sellers of Acquired Centers").
The Company does not expect to incur significant additional debt in the near
future and expects to rely on its existing cash balances, of approximately
$18,242,000 at August 31, 1998, and its ability to enter into operating leases
to fund expansions and equipment replacement at its centers. Assuming that the
Company executes definitive documents with respect to the Senior Notes
consistent with the agreement in principle, management believes that, based upon
current levels of operating cash flows, the Company will have sufficient funds
available to finance its needs through 1998. There can be no assurance, however,
that management's belief as to available funds for 1998 will prove accurate or
that the Company will be able to enter into operating leases on terms acceptable
to the Company.
 
RECENT LITIGATION
 
    As described below under "Certain Relationships and Related
Transactions--Independent Committee Investigation into Related-Party
Transactions" beginning on page 63, the Company and its directors and certain
former officers have been named as defendants in several actions filed in state
and federal court arising out of the events described below involving, among
other matters, allegations against the Company's practices regarding
related-party transactions and securities fraud. As the cases are still in their
preliminary stages, their outcomes cannot presently be determined. A decision
adverse to the Company in these cases could have a material adverse effect on
the Company, its cash flow, financial condition and results of operation. In
addition, the Company may incur substantial legal and other expenses in
connection with the defense of these cases which could have a material adverse
effect on the Company's cash flows, financial condition and results of
operation. The Company cannot currently estimate the amount or timing of such
expenses or the time frame in which these cases will ultimately be resolved.
 
EFFECTS OF GRANT OF REPURCHASE AND PURCHASE PRICE REMEDIES AND EARNOUT RIGHTS TO
  SELLERS OF ACQUIRED CENTERS
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration therefor, the
Company granted rights to have such shares registered for resale pursuant to the
federal securities laws. In connection with certain of such acquisitions, the
Company has granted specific remedies to the sellers in the event the
registration statement covering the relevant shares was not declared effective
by the Securities and Exchange Commission within an agreed-upon period of time,
including the right to require the Company to repurchase the shares issued to
such seller. As a result of the Company's failure to register such shares by the
required dates, the Company has become obligated to repurchase such shares
issued in connection with such acquisition. As of September 1, 1998, the Company
had not registered any shares of Common Stock issued in connection with the
Company's 1997 acquisitions under a registration statement declared effective by
the SEC. As of June 30, 1998, the Company had reflected $5,509,000 as Common
Stock Subject to Redemption on its Consolidated Balance Sheets which is related
to shares that the Company is, has agreed to or may be required to repurchase.
During the first six months of 1998, the Company paid $3,311,000 to sellers who
exercised their rights to have shares of Common Stock repurchased. In addition,
the Company expects to pay an additional $5,509,000 during the remainder of 1998
($3,696,000 of which was due and payable on June 3, 1998 (the "June 1998
Repurchase Obligation") but has not yet been paid by the Company) in connection
with the settlement of certain repurchase obligations of the Company subject,
under certain circumstances, to the consent of the Senior Notes holders. With
respect to the June 1998 Repurchase Obligation which remains due and payable,
the Company is in discussions with the sellers to whom such obligations are owed
and the Senior Note holders regarding the timing and satisfaction of the June
1998 Repurchase Obligation.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay (in additional shares
and/or cash) to the sellers an amount equal to the shortfall in the value of the
issued shares in the event the market value of such shares at the relevant
effective date of
 
                                       6
<PAGE>
the registration statement or other negotiated date is less than the market
value of such shares as of the closing of the acquisition or, in other cases, as
of the execution of the relevant acquisition agreement (referred to as "Price
Protection"). Based upon the closing sales price of the Company's Common Stock
on September 1, 1998 ($4.00 per share), such shortfall would be approximately
$3,351,000, including Price Protection obligations related to the shares which
have repurchase obligations referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differs for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both.
 
    Although the Company possesses the option, in certain of such cases, to pay
certain of such amounts in shares of Common Stock, payment of significant cash
funds to sellers in the event such remedies or earnout provisions are triggered
could have a material adverse effect on the Company's cash flow and financial
condition. In addition, the Company may be required to finance all or a portion
of any such cash payments from third-party sources. No assurance can be given
that such capital will be available on terms acceptable to the Company. In
addition, the issuance by the Company of shares of Common Stock in payment of
any such owed amounts could be dilutive to the Company's stockholders.
 
EFFECTS OF FAILURE TO COMPLY WITH TERMS OF THE CONVERTIBLE PREFERRED STOCK
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement, dated July 21, 1997, and the Registration Rights Agreement, dated
July 21, 1997, as amended, between the Company and RGC International, LDC
("RGC") (hereinafter referred to as the "RGC Agreements"), the Company issued
18,000 shares of Series C Convertible Preferred Stock, $1,000 stated value per
share (the "Series C Preferred Stock") to RGC. Under the RGC Agreements, the
Company was required to use its best efforts to include the shares of Common
Stock issuable upon conversion of the Series C Preferred Stock (the "RGC
Conversion Shares") in an effective Registration Statement on Form S-3 not later
than October 1997. As amended the RGC Agreements provide for monthly penalties
("RGC Registration Penalties") in the event that the Company fails to register
the Conversion Shares prior to October 1997 with such penalties continuing until
July 23, 1998.
 
    As a result of the Company's failure to register the RGC Conversion Shares
at various dates on or after December 31, 1997, the Company: (i) issued warrants
to RGC to acquire 389,000 shares of Common Stock at an exercise price ranging
from $34.86 to $38.85 per share, subject to reset in November 1998 (such
warrants having an estimated value for accounting purposes, of $3,245,000); and
(ii) issued interest bearing promissory notes (the "RGC Penalty Notes") in the
aggregate principal amount of $2,450,000 due October 15, 1998. The principal
amount of and interest accrued on the RGC Penalty Notes may be converted, at the
option of the Company or RGC in certain circumstances, into additional shares of
Series C Preferred Stock or Common Stock. Pursuant to an amendment to the RGC
Agreements entered into in June 1998, the Company will no longer incur any
monthly penalties for failure to register the RGC Conversion Shares following
July 23, 1998. However, if the RGC Conversion Shares are not registered as of
September 15, 1998, RGC may demand a one-time penalty of $1,550,000 (the
"September 1998 Penalty"), payable, at the option of RGC, in cash or additional
shares of Common Stock. There can be no assurance that the Company will be able
to register the RGC Conversion Shares by such date or that the Company will be
able to pay the RGC Penalty Notes when due or the September 1998 Penalty, if
such payment becomes due.

LOSSES FROM CERTAIN CENTERS; IMPAIRMENT OF CERTAIN ASSETS
 
    Certain centers that the Company acquired in connection with multiple center
acquisitions since January 1996 have generated losses. With respect to these
centers, the Company has utilized its working capital to fund the operations of
such centers. During 1997, the Company recorded a $12,962,000 loss from the
impairment of goodwill and other long-lived assets. This loss consisted of the
write-off of goodwill of $10,425,000, covenants not to compete of $118,000 and
fixed assets of $2,419,000. The write-down of fixed assets primarily relates to
imaging equipment. Substantially all of the impairment relates to eight of the
Company's diagnostic imaging centers which were under performing. The Company
has recorded impairment losses for these centers because the sum of the expected
future cash flows, determined based on an assumed continuation of current
operating methods and structures, does not cover the carrying value of the
related long-lived assets. Furthermore, the Company has determined to sell or
close approximately eight imaging centers during the third and fourth quarters
of 1998. In most cases, the Company decided to sell or close these centers due
to general competitive pressures and their close proximity to other imaging
centers of the Company which have more advanced imaging equipment. The Company
expects to incur a charge of between $3,000,000 and $4,000,000 during the third
quarter of 1998 related to these imaging centers. Such charge will consist of
(i) the write-off of fixed assets and other assets of between $2,000,000 and
$2,600,000 and (ii) reserve for costs to exit facility and equipment leases of
between $1,000,000 and $1,400,000.
 
    The Company continues to investigate the underlying causes of
under-performance by certain centers to determine what actions, if any, may be
taken to improve the future operating performance of such centers. There can be
no assurance, however, that additional assets of the Company will not be
impaired in the future or that the future operating performance of the Company's
centers with a history of losses will improve. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
ACQUISITION STRATEGY; MANAGEMENT OF GROWTH
 
    One of the Company's objectives is to continue to acquire diagnostic imaging
centers and integrate them into the Company's operations. Successfully
accomplishing this goal depends upon a number of factors, including the
Company's ability to find suitable acquisition candidates, negotiate
acquisitions on acceptable terms, obtain necessary financing on acceptable
terms, retain key personnel of the acquired entities, hire and train other
competent managers, and effectively and profitably integrate the operations of
the acquired businesses into the Company's existing operations. The process of
integrating acquired businesses may require a significant amount of resources
and management attention which could temporarily detract from attention to the
day-to-day business of the Company and which may be prolonged due to unforeseen
circumstances. The Company's ability to manage its growth effectively will
require it to continue to improve its operational, financial and management
information systems and controls (including improving and standardizing of its
billing systems), and to attract, retain, motivate and manage employees
effectively. The failure of the Company to manage growth in its business
effectively would have a material adverse effect on its results of operations.
 
    Future acquisitions may be financed through the incurrence of additional
indebtedness or the issuance of equity securities. The issuance by the Company
of additional Common Stock in connection with acquisitions could be dilutive to
Company stockholders. In addition, because the Common Stock has experienced
significant market price fluctuations recently, sellers of acquisition targets
may be hesitant to accept shares of Common Stock in payment of all or portions
of the purchase price of centers unless they are provided with suitable price
protection rights. The grant and ultimate exercise of any such rights could
result in significant dilution to existing shareholders. See "Effects of Grant
of Purchase Price Remedies and Earnout Rights to Sellers of Acquired Centers."
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 Company.

REDUCTIONS 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 healthcare. In certain areas, the payors are subject to regulations
which limit the amount of payments. Discussions within the Federal government
regarding national healthcare reform are emphasizing containment of healthcare
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, including the numbers of
procedures performed, of rendering diagnostic services to the members. Services
provided under these contracts are expected to become an increasingly
significant part of the Company's business. The inability of the Company to
properly manage the administration of capitated contracts could materially
adversely effect the Company. Although patients are ultimately responsible for
payment for services rendered, substantially all of the Company's 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 Company's respective imaging
centers' revenues, profitability and cash flow.
 
    The Company's management believes that overall reimbursement rates will
continue to gradually decline for some period of time due to factors such as the
expansion of managed care organizations and continued national healthcare reform
efforts (including future reductions in Medicare and Medicaid reimbursement
rates). The Company enters into contractual arrangements with managed care
organizations which, due to the size of their membership, are able to command
reduced rates for services. Although during 1997 and the first six months of
1998, the aggregate volume of procedures performed by the Company at its centers
has remained relatively constant (and therefore has not offset the reduction in
reimbursement rates per procedure), the Company expects these agreements, over
time, to increase the number of procedures performed due to the additional
referrals from these managed care entities. However, there can be no assurance
that the potential increased volume of procedures associated with these
contractual arrangements will offset the reduction in reimbursement rate per
procedure.
 
PERSONAL INJURY REVENUE
 
    A significant percentage of the Company's net service revenues from imaging
centers is derived by providing imaging services to individuals involved in
personal injury claims, mainly involving automobile accidents. Imaging revenue
derived from person injury claims, mainly involving automobile accidents,
represented approximately 24% of the Diagnostic Imaging business net service
revenues for 1997. Due to the greater complexity in processing receivables
relating to personal injury claims with automobile insurance carriers (including
dependency on the outcome of settlements or judgments for collections directly
from such individuals), such receivables typically require a longer period of
time to collect, compared to the Company's other receivables and, in the
experience of the Company, incur a higher bad debt expense.
 
    While the collection process employed by the Company may vary from
jurisdiction to jurisdiction, the processing of a typical personal injury claim
generally commences with the Company obtaining and verifying automobile, primary
health, and secondary health insurance information at the time services are
rendered. The Company then generates and sends a bill to the automobile
insurance carrier, which under state law, typically has an extended period of
time (usually up to 105 days) to accept or reject a claim. The amount of
documentation required by the automobile insurance carriers to support a claim
is substantially in excess of what most other payors require and carriers
frequently request additional information after the initial submission of a
claim. If the individual is subject to a co-payment or deductible under the
automobile insurance policy or has no automobile insurance coverage, the Company
will generally bill the individual's primary and secondary health policies for
the uncovered balance. The automobile insurance carrier may reject coverage or
fail to accept a claim within the statutory time limit on the basis of, among
 
                                       9
<PAGE>
other reasons, the failure to provide complete documentation. In such
circumstances, the Company generally pursues arbitration, which typically takes
up to 90 days for a judgment, to collect from the carrier.
 
    The Company will then pursue collection of the remaining receivable from the
individual. Although the Company attempts to bill promptly after providing
services and typically requests payment upon receipt of invoice, the Company
generally defers aggressive collection efforts for the remaining balance until
the personal injury individual's claim is resolved in court, which frequently
takes longer than a year and may take as long as two or three years.
Consequently, the Company's practice is to obtain a written assurance from the
individual and the individual's legal counsel, under which the individual
confirms in writing his or her obligation to pay the outstanding balance
regardless of the outcome of any settlement or judgment of the claim.
Consequently, the Company's services with respect to the personal injury claim
are not contingent. If the settlement or judgment proceeds received by the
individual are insufficient to cover the individual's obligation to the Company,
the Company either (i) accepts a reduced amount in full satisfaction of the
individual's outstanding obligation, or (ii) commences collection proceedings,
which may ultimately result in the Company taking legal action to enforce its
collection rights against the individual regarding all uncollected accounts.
 
    As a result of the foregoing, the average age of receivables relating to
personal injury claims is greater than for non-personal injury claim
receivables. Significant delays in the collection or the inability to collect
receivables relating to personal injury claims or the refusal of insurance
companies to pay the higher reimbursement rates typically associated with
personal injury claims could have a material adverse effect on the Company's
diagnostic imaging operations.
 
RESTRICTIONS IMPOSED BY GOVERNMENT REGULATION
 
    The healthcare industry is highly regulated. The ownership, construction,
operation, expansion and acquisition of outpatient diagnostic imaging 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 and other required certificates for certain
types of healthcare 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 for patient services.
The Federal Anti-Kickback Act of 1977, as amended (the "Anti-Kickback Act")
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 Company does not believe that it is
operating in violation of this law, the scope of the law remains somewhat
unclear and there is no assurance that the Company would prevail in its
position. 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 Anti-Kickback Act. 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 Anti-Kickback Act, 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 Anti-Kickback Act.
 
    The Federal Omnibus Budget Reconciliation Act of 1989, as amended by the
Federal Omnibus Budget Reconciliation Act of 1993, contains provisions that,
unless an exception applies, restrict physicians from making referrals to, among
others, providers of MR and other radiological services for services to be
rendered to Medicare or Medicaid patients in which the physicians have a
"financial relationship" or an ownership interest or with which they have a
compensation arrangement (the so-called "Stark Law"). The Stark Law provides
exceptions for certain types of employment and contractual relationships. The
 
                                       10
<PAGE>
Company believes that it is in compliance with the Stark Law, but there is no
assurance that the Company will prevail in its position if challenged.
 
    The State of Florida also enacted in 1992 an anti-kickback statute
substantially similar in scope to the Anti-Kickback Act. Although the Company
does not believe that it is 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 Company would prevail in its position.
 
    The States of Florida, Illinois, New Jersey, New York, Maryland and
Pennsylvania in which the Company currently operates centers have enacted laws
that restrict or prohibit physicians from referring patients to healthcare
facilities in which such physicians have a financial interest. Although the
Company does not believe that these laws will have a material adverse effect on
its 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 Company does
business, will not adopt similar or more restrictive laws or regulations that
could have such a material adverse effect.
 
    All states where the Company has imaging centers have enacted Certificate of
Need laws to facilitate healthcare planning by placing limitations on the
purchase of certain major medical equipment and certain other capital
expenditures. These statutes, together with their implementing regulations,
could limit the Company's ability to acquire new imaging facilities and imaging
equipment or expand or replace its equipment at existing centers, and no
assurances can be given that the required regulatory approvals for any future
acquisitions, expansions or replacements will be granted to the Company.
 
    The Company continues to review all aspects of its operations and believes
that it complies in all material respects with applicable provisions of the
Anti-Kickback Act, the Stark Law and applicable state laws governing fraud and
abuse as well as licensing and certification, although because of the broad and
sometimes vague nature of these laws and requirements, there can be no assurance
that an enforcement action will not be brought against the Company or that the
Company will not be found to be in violation of one or more of these regulatory
provisions. Further, there can be no assurance that new laws or regulations will
not be enacted, or existing laws or regulations interpreted or applied in the
future in such a way as to have a material adverse impact on the Company, or
that Federal or state governments will not impose additional restrictions upon
all or a portion of the Company's activities, which might adversely affect the
Company's business.
 
CORPORATE PRACTICE OF MEDICINE AND FEE SPLITTING
 
    The Company presently operates imaging centers in New York, New Jersey,
Pennsylvania, Maryland, Massachusetts, Ohio, Illinois, Florida, California and
Arkansas. The laws of many states prohibit unlicensed, non-physician-owned
entities or corporations (such as the Company) from performing medical services,
or in certain instances, physicians from splitting fees with non-physicians,
such as the Company. The Company does not believe that it engages in the
unlicensed practice of medicine or the delivery of medical services in any state
where it is prohibited, and is generally not licensed to practice medicine in
states which permit such licensure. Professional medical services, such as the
interpretation of MRI scans, are separately provided by licensed Interpreting
Physicians, as independent contractors, pursuant to agreements with the Company.
At each of the Company's centers, all medical services are performed exclusively
by Physician Groups, generally consisting exclusively of radiologists, with whom
the Company enters into independent contractor agreements. Pursuant to these
agreements, the Company, among other duties, provides to the Physician Group the
diagnostic imaging facility and equipment, performs all marketing and
administrative functions at the centers and is responsible for the maintenance
and servicing of the equipment and leasehold improvements. The Physician Group
is solely responsible for, and has complete and exclusive control over, all
medical and professional services performed at the centers, including, most
importantly, the interpretation of diagnostic images as well as the supervision
of technicians, and medical related quality assurance and communications with
referring physicians. The Company's
 
                                       11
<PAGE>
employees do not perform professional medical services at the centers.
Consequently, the Company does not believe that it engages in the practice of
medicine in jurisdictions which prohibit or permit the corporate practice of
medicine. The Company performs only administrative and technical services and
does not exercise control over the practice of medicine by physicians at the
centers or employ physicians to provide medical services.
 
    In many jurisdictions, however, the laws restricting the corporate practice
of medicine and fee-splitting have been subject to limited judicial and
regulatory interpretation and, therefore, there is no assurance that, upon
review, some of the Company's activities would not be found to be in violation
of such laws. If such a claim were successfully asserted against it, the Company
could be subject to civil and criminal penalties. Imposition of civil or
criminal penalties against the Company could have a material adverse effect on
its operations, cash flows and financial condition.
 
POTENTIAL ADVERSE EFFECT OF CAPITATION CONTRACTS
 
    The Company has entered into a number of "capitated contracts" with third
party payors which typically provide for payment of a fixed fee per month on a
per member basis, without regard to the amount or scope of services actually
rendered. Because the obligations to perform services are not related to the
payments, it is possible that either the cost or the value of the services
performed may significantly exceed the fees received, and there may be a
significant period between the time the services are rendered and payment is
received. Approximately 2% of the Company's net service revenues in 1997 was
derived from capitated contracts. While prior to entering into any such
contracts the Company carefully analyzes the potential risks of capitation
arrangements, there can be no assurances that any capitated contracts to which
the Company is a party or which it may enter into in the future will not
generate significant losses to the Company.
 
    In addition, certain types of capitation agreements, may be deemed a form of
risk contracting. Many states limit the extent to which any person can engage in
risk contracting, which involves the assumption of a financial risk with respect
to providing services to a patient. If the fees received by the Company are less
than the cost of providing the services, the Company may be deemed to be acting
as a de facto insurer. In some states, only certain entities, such as insurance
companies, HMOs and independent practice associations, are permitted to contract
for the financial risk of patient care. In such states, risk contracting in
certain cases has been deemed to be engaging in the business of insurance. The
Company believes that it is not in violation of any restrictions on risk bearing
or engaging in the business of insurance. If the Company is held to be
unlawfully engaged in the business of insurance, such a finding could result in
civil or criminal penalties or require the restructuring of some or all of the
Company's operations, which could have a material adverse effect upon the
Company's business.
 
COMPETITION; RELIANCE ON REFERRALS
 
    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 Company believes that principal competitors in each of its
markets are hospitals, independent or management company owned imaging centers,
individual-owned imaging centers and mobile MR units. Many of these competitors
have greater financial and other resources than the Company. Principal
competitive factors include facility location, type and quality of equipment,
quality and timeliness of test results, ability to develop and maintain
relationships with referring physicians, convenience of scheduling and
availability of patient appointment times and the pricing of services. These
factors impact the referring physician's decision to direct a patient to an
imaging center. Competition for physician referrals can also be affected by the
ownership or affiliation of competing centers or hospitals. In addition, managed
care has affected the availability of referrals by approving only a certain
number of centers in a given geographic region. The competitive environment
which the Company faces could result in lower patient volume or in an adverse
change in payor mix.
 
                                       12
<PAGE>
    MR systems compete with a variety of other scanning technologies which are
available in physicians offices, hospitals and other diagnostic imaging centers.
Competition with other imaging modalities is generally based on the nature of
the medical procedure to be performed and the condition of the patient. The use
of MR imaging as a diagnostic tool continues to gain both professional and
public acceptance as MR imaging and diagnostic techniques improve, equipment
software is enhanced and attention is directed to MR's diagnostic successes. The
Company's performance is dependent upon physician and patient confidence in the
superiority of its MR imaging and service over other competing modalities and
systems.
 
    There are a number of manufacturers of MR imaging systems. These
manufacturers' marketing efforts can be expected to stimulate others, including
hospitals, to purchase and install the MR systems. Periodically, manufacturers
introduce innovations or newly designed MR systems with enhanced features.
Therefore, the Company encounters strong competition from other MR diagnostic
systems with innovative or enhanced features installed in the areas where the
Company has installed its MR systems, as well as strong competition in its
endeavors to acquire new locations.
 
    The temporary healthcare 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. StarMed competes with several companies which are larger and may possess
greater financial and other resources.
 
DEPENDENCE ON QUALIFIED INTERPRETING PHYSICIANS
 
    The Company's strategy of maintaining the high quality of its services is
dependent upon its ability to obtain and maintain arrangements with qualified
Interpreting Physicians at each of its centers. No assurance can be given that
the Company's contractual arrangements with Interpreting Physician groups at
each of the Company's centers can be maintained on terms advantageous to the
Company. No assurance can be given that the Interpreting Physicians with whom
the Company has contracts will perform satisfactorily or continue to practice in
the markets served by its imaging centers. In addition, with respect to the
acquired 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 Company's success is significantly
dependent on the ability of these physicians to attract patient referrals,
thereby enabling the Company's centers to operate profitably. Agreements with
Interpreting Physicians generally range from one to ten years and permit
termination only for cause. Many agreements prohibit the Interpreting Physician
from performing professional interpreting services for a competitor within a
defined geographic distance from the Company's center which may vary depending
upon the relevant demographics and density of the immediate region. Such
restrictive covenants are customarily in effect from one to five years following
the termination of the agreements. The inability of these physicians to attract
sufficient referrals, the termination of their agreements with the Company or
the inability of the Company to enforce the restrictive covenants contained in
the agreements could have a material adverse effect on the Company's financial
condition and operating results.
 
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
Company believes that its 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 Company may be compelled to acquire new
equipment, which could have a material adverse effect on its financial
condition, results from operations and cash flow. In addition, certain of the
Company's centers compete against local centers which contain more advanced
imaging equipment or provide additional modalities.
 
                                       13
<PAGE>
MALPRACTICE LIABILITY CLAIMS AND INSURANCE
 
    Although the Company provides administrative, financial and technical
services and is not engaged in the practice of medicine, the diagnostic imaging
and temporary staffing businesses entail the risk of professional liability
claims. Consequently, the Company may be named as a co-defendant in medical
malpractice claims. The Company's exposure to such liability is reduced for its
imaging centers because Interpreting Physicians are required to purchase and
carry their own medical malpractice insurance. Similarly, the Company's nursing
personnel perform services in accordance with treatments prescribed by
third-party Physicians or under hospital supervision. Nevertheless, the Company
maintains general liability insurance and professional liability insurance for
both its diagnostic imaging business and its temporary staffing business in
amounts deemed adequate by management of the Company. The Company is subject to
one claim seeking $12.5 million in damages, which is in excess of the Company's
insurance coverage of $1,000,000 per incident, as well as six additional
lawsuits which do not specify the amount sought to be recovered. Adverse
determinations against the Company with respect to all such claims or the filing
of malpractice claims against the Company in the future could have a material
adverse effect on the Company's financial condition, results of operations and
cash flow.
 
DEVELOPMENT OF NEW CENTERS
 
    Although the primary focus of the Company's growth strategy has been on
acquisitions of existing centers rather than developing new centers, the Company
may also, from time to time, pursue the development of new centers. Developing
new centers entails the same risks as establishing a new business. The
likelihood of success of a newly developed center must therefore be considered
in light of the initial development and operating complexities, expenses,
difficulties, and delays frequently encountered by a new business and the
competitive environment in which the new business will operate. In addition, new
centers may incur significant operating losses during their initial operations,
which could materially adversely affect the Company's operating results, cash
flows and financial condition.
 
EFFECTS OF FAILURE TO MAINTAIN NASDAQ NATIONAL MARKET LISTING
 
    On May 14, 1998, management appeared before the Nasdaq Qualifications
Hearing Panel (the "Panel"). This hearing resulted from the Company's failure to
file timely its Form 10-K for 1997 and was held to determine if the Company's
Common Stock should continue to be listed on The Nasdaq Stock Market. On May 29,
1998, the Company was advised that the Panel determined to continue the listing
of the Company's Common Stock on the Nasdaq Stock Market subject to certain
conditions. The Company was required to file its Quarterly Report on Form 10-Q
for the quarter ended March 31, 1998 on or before June 12, 1998, which the
Company was able to do, and to evidence compliance with either Nasdaq's minimum
net tangible assets test or one of Nasdaq's alternative requirements by July 24,
1998. In order to meet one of Nasdaq's alternative listing requirements, the
Company effected a one-for-three reverse stock split of its Common Stock on July
24, 1998. On July 28, 1998, the Panel notified the Company that the Company had
complied with Nasdaq's continued listing qualifications and that the Common
Stock would continue to be listed on The Nasdaq Stock Market. Nevertheless,
there can be no assurance that in the future the Common Stock will meet the
continued listing qualifications of The Nasdaq Stock Market. Among other
consequences, delisting from The Nasdaq Stock Market could cause a decline in
the market price of the Common Stock and difficulty in the ability of the
Company in obtaining future equity financing or in using its Common Stock as
consideration for acquisitions.
 
ABSENCE OF DIVIDENDS
 
    The Company has never paid cash dividends and 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 the Company is within the discretion of its Board of
Directors and will be dependent on the earnings, financial condition and capital
requirements of the
 
                                       14
<PAGE>
Company, as well as any other factors deemed relevant by its Board of Directors.
In addition, the payment by the Company of cash dividends is presently limited
by the agreement related to the issuance of the Senior Notes.
 
CERTAIN ANTI-TAKEOVER MEASURES
 
    Certain provisions of the Company's Certificate of Incorporation, as well as
Delaware corporate law and the Company's Stockholder Rights Plan (the "Rights
Plan"), may be deemed to have anti-takeover effects and may delay, defer or
prevent a takeover attempt that a stockholder might consider in its best
interest. Such provisions also may adversely affect prevailing market prices for
the Common Stock. Certain of such provisions allow the Company's Board of
Directors to issue, without additional stockholder approval, preferred stock
having rights senior to those of the Common Stock. In addition, the Company is
subject to the anti-takeover provisions of Section 203 of the Delaware General
Corporation Law, which prohibits the Company from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed matter.
In September 1996, the Company adopted the Rights Plan, pursuant to which
holders of the Common Stock received a distribution of rights to purchase
additional shares of Common Stock, which rights become exercisable upon the
occurrence of certain events. Although the Rights Plan was adopted by the
Company to give its Board of Directors significantly more time to properly
consider and to respond to an acquisition proposal, it could have the effect of
discouraging or hindering an unsolicited offer to acquire the Company at
effective valuations which are above the current market capitalization of the
Company.
 
VOLATILITY OF STOCK PRICE
 
    The market price of the Common Stock has been and may continue to be
volatile. Recently, the stock market in general and the shares of healthcare and
diagnostic imaging services companies in particular have experienced significant
price fluctuations. These broad market and industry fluctuations may adversely
affect the market price of the Common Stock. Factors such as quarterly
fluctuations in results of operations, the timing and terms of future
acquisitions and general conditions in the healthcare industry may have a
significant impact on the market price of the Common Stock.
 
SALES BY SELLING STOCKHOLDERS; POTENTIAL FOR DILUTION
 
    All of the Shares being offered hereby are offered solely by the Selling
Stockholders who are not restricted as to the prices at which they may sell the
Shares. Shares sold below the then current level at which the shares of Common
Stock are trading may adversely affect the market price of the Common Stock. The
outstanding shares covered by this Prospectus and the shares of Common Stock
covered by this Prospectus which are issuable as of September 8, 1998 upon the
conversion or exercise of the Company's Series C Preferred Stock, convertible
notes and certain warrants represent 49.5% of the outstanding shares of Common
Stock as of September 8, 1998 after giving effect to the issuance of shares of
Common Stock upon the conversion or exercise of the Series C Preferred Stock,
convertible notes and certain warrants, which shares are being offered by this
Prospectus.
 
    As of September 1, 1998, 15,500 shares of the Company's Series C Preferred
Stock were issued and outstanding. Each share of the Series C Preferred Stock is
convertible into such number of shares of Common Stock as is determined by
dividing the stated value ($1,000) of each share of Series C Preferred Stock
plus 3% per annum from the closing date to the conversion date by the lesser of
(i) $62.10 or (ii) the average of the daily closing bid prices for the Common
Stock for the five (5) consecutive trading days ending five (5) trading days
prior to the date of conversion. On June 18, 1998, 2,500 shares of Series C
Preferred Stock were converted into 373,220 shares of Common Stock. If converted
on September 8, 1998, the remaining 15,500 shares of Series C Preferred Stock
would have been convertible into approximately 3,119,167 shares of Common Stock.
Based on the closing price of the Common Stock on October 1, 1998
 
                                       15

($2.625) the outstanding Preferred Stock would have been converted into
approximately 6,116,848 shares of Common Stock. Depending on market conditions
at the time of conversion, the number of shares issuable could prove to be
significantly greater in the event of a decrease in the trading price of the
Common Stock. As a result of the Company's failure to register the RGC
Conversion Shares at various dates on or after December 31, 1997, the Company:
(i) issued warrants to RGC to acquire 389,000 shares of Common Stock at an
exercise price ranging form $34.86 to $38.85 per share, subject to reset in
November 1998 (such warrants having an estimated value for accounting purposes,
of $3,245,000); and (ii) issued interest bearing promissory notes (the "RGC
Penalty Notes") in the aggregate principal amount of $2,450,000 due October 15,
1998. The principal amount of and interest accrued on the RGC Penalty Notes may
be converted, at the option of the Company or RGC in certain circumstances, into
additional shares of Series C Preferred Stock or Common Stock. Pursuant to an
amendment to the RGC Agreements entered into in June 1998, the Company will no
longer incur any monthly penalties for failure to register the RGC Conversion
Shares following July 23, 1998. However, if the RGC Conversion Shares are not
registered as of September 15, 1998, RGC may demand a one-time penalty of
$1,550,000 (the "September 1998 Penalty"), payable, at the option of RGC, in
cash or additional shares of Common Stock. There can be no assurance that the
Company will be able to register the RGC Conversion Shares by such date or that
the Company will be able to pay the RGC Penalty Notes when due or the September
1998 Penalty, if such payment becomes due. Purchasers of Common Stock could
therefore experience substantial dilution upon conversion of the Series C
Preferred Stock and the RGC Penalty Notes and the exercise of such warrants. The
shares of Series C Preferred Stock are not registered and may be sold only if
registered under the Act or sold in accordance with an applicable exemption from
registration, such as Rule 144. The shares of Common Stock into which the Series
C Preferred Stock may be converted and the shares underlying such warrants are
being registered pursuant to the Registration Statement of which this Prospectus
is a part.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
    The Company's Common Stock had been traded on the National Association of
Securities Dealers Automated Quotation System (NASDAQ) National Market, under
the symbol MRII, since November 3, 1995, and on the NASDAQ SmallCap Market prior
thereto. From April 20, 1998 through June 18, 1998 the Company's Common Stock
traded under the symbol MRIIE to reflect the fact that Nasdaq had commenced
proceedings to determine whether or not the Company's Common Stock should
continue to be traded on the Nasdaq Stock Market as a result of the Company's
failure to file its Annual Report on Form 10-K for the year ended December 31,
1997 in a timely manner. On May 29, 1998, the Company was advised that the Panel
determined to continue the listing of the Company's Common Stock on The Nasdaq
Stock Market subject to certain conditions. The Company was required to file its
Quarterly Report on Form 10-Q for the quarter ended March 31, 1998 on or before
June 12, 1998, which the Company was able to do, and to evidence compliance with
either Nasdaq's minimum net tangible assets test or one of Nasdaq's alternative
requirements by July 24, 1998. In order to meet one of Nasdaq's alternative
listing requirements, the Company effected a one-for-three reverse stock split
of its Common Stock on July 24, 1998. On July 28, 1998, the Panel notified the
Company that the Company had complied with Nasdaq's continued listing
qualifications and that the Common Stock would continue to be listed on The
Nasdaq Stock Market. Nevertheless, there can be no assurance that in the future
the Common Stock will meet the continued listing qualifications of The Nasdaq
Stock Market.
 
    The following table sets forth for the periods indicated below the high and
low sales prices per share of the Common Stock as reported by NASDAQ and gives
effect to the one-for-three reverse stock split of the Common Stock effected on
July 24, 1998:

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF CONTINUING OPERATIONS
 
    REVENUE RECOGNITION
 
    At each of the Company's diagnostic imaging centers, all medical services
are performed exclusively by physician groups (the "Physician Group" or the
"Interpreting Physician"), generally consisting of radiologists with whom the
Company has entered into independent contractor agreements. Pursuant to these
agreements, the Company has agreed to provide equipment, premises, comprehensive
management and administration, including responsibility for billing and
collection of receivables, and technical imaging services to the Interpreting
Physician.
 
    Net service revenues are reported, when earned, at their estimated net
realizable amounts from patients, third party payors and others for services
rendered at contractually established billing rates which generally are at a
discount from gross billing rates. Known and estimated differences between
contractually established billing rates and gross billing rates (referred to as
"contractual allowances") are recognized in the determination of net service
revenues at the time services are rendered. Subject to the foregoing, the
Company's diagnostic imaging centers recognize revenue under one of the three
following types of agreements with Interpreting Physicians:
 
        TYPE I--The Company receives a technical fee for each diagnostic imaging
    procedure performed at a center, the amount of which is dependent upon the
    type of procedure performed. The fee included in revenues is net of
    contractual allowances. The Company and the Interpreting Physician
    proportionally share in any losses due to uncollectible amounts from
    patients and third party payors, and the Company has established reserves
    for its share of the estimated uncollectible amount. Type I net service
    revenues for 1997 and the six months ended June 30, 1998 were $80,818,000,
    or 56% of revenues, and $50,283,000, or 54% of revenues, respectively.
 
        TYPE II--The Company bills patients and third party payors directly for
    services provided and pays the Interpreting Physicians either (i) a fixed
    percentage of fees collected at the center, or (ii) a contractually fixed
    amount based upon the specific diagnostic imaging procedures performed.
    Revenues are recorded net of contractual allowances and the Company accrues
    the Interpreting Physicians fee as an expense on the Consolidated Statements
    of Operations. The Company bears the risk of loss due to uncollectible
    amounts from patients and third party payors, and the Company has
    established reserves for the estimated uncollectible amount. Type II net
    service revenues for 1997 and the six months ended June 30, 1998 were
    $55,016,000, or 38% of revenues, and $36,618,000, or 39% of revenues,
    respectively.
 
        TYPE III--The Company receives from an affiliated physician association
    a fee for the use of the premises, a fee per procedure for acting as billing
    and collection agent and a fee for administrative and technical services
    performed at the centers. The affiliated physician association contracts
    with and pays directly the Interpreting Physicians. The Company's fee, net
    of an allowance based upon the affiliated physician association's ability to
    pay after the association has fulfilled its obligations (i.e., estimated
    future net collections from patients and third party payors less facility
    lease expense and Interpreting Physicians fees), constitutes the Company's
    net service revenues. Since the Company's net service revenues are dependent
    upon the amount ultimately realized from patient and third party
    receivables, the Company's revenue and receivables have been reduced by an
    estimate of patient and third party payor contractual allowances, as well as
    an estimated provision for uncollectible amounts from patients and third
    party payors. Type III net service revenues for 1997 and the six months
    ended June 30, 1998 were $8,342,000, or 6% of revenues, and $6,747,000, or
    7% of revenues, respectively.
 
    Revenues derived from Medicare and Medicaid are subject to audit by such
agencies. The Company is not aware of any pending audits.
 
                                       19
<PAGE>
    The fees received or retained by the Company under the three types of
agreements with Interpreting Physicians described above, expressed as a
percentage of gross billings net of contractual allowances for the imaging
services provided, range from 78% to 93% for the Type I agreements, 80% to 93%
for the Type II agreements and 80% to 89% for the Type III agreements. These
agreements generally have terms ranging from one to ten years.
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
Divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold StarMed to RehabCare
Group, Inc. for $33 million (the "StarMed Sale"). Due to the StarMed Sale, the
results of operations of StarMed are herein reflected in the Company's
Consolidated Statements Of Operations as discontinued operations.
 
    On July 24, 1998, the Company effected a one-for-three reverse stock split
of its Common Stock. The information in this Prospectus gives effect to such
reverse stock split.
 
    SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997
 
    For the six months ended June 30, 1998, total Company's net service revenues
were $93,648,000 versus $64,718,000 for the six months ended June 30, 1997, an
increase of $28,930,000 or 45%.
 
    The increase is due to the timing of various 1997 acquisitions which were
responsible for $35,093,000 of the increase. Offsetting this increase were
centers that were operated by the Company for all of 1997 which decreased
$7,340,000, or 15%, to $42,223,000 for the six months ended June 30, 1998 from
$49,563,000 for the same period in 1997, primarily as a result of higher
contractual allowances, as a percentage of gross billings, in the 1998 second
quarter, and a modality mix change toward lower priced procedures. Aggregate
procedure volumes for these imaging centers were relatively constant in the six
months ended June 30, 1998 as compared to the six months ended June 30, 1997.
 
    Contractual allowances are largely dependent upon reimbursement rates from
third party payors, including Medicare, Medicaid and managed care providers.
Management believes that it is likely that the Company's overall reimbursement
rates will gradually decline for some period of time, due to factors such as the
expansion of managed care organizations and continued national healthcare reform
efforts. The Company intends to attempt to mitigate the impact of any decline in
reimbursement rates by decreasing costs and increasing referral volumes. If the
rate of decline in reimbursement rates were to increase materially, or if the
Company is unsuccessful in reducing its costs or increasing its volumes, the
Company's results could be materially and adversely affected.
 
    Diagnostic Imaging revenue derived from personal injury claims, mainly
involving automobile accidents, represented approximately 18% of the Diagnostic
Imaging business net service revenues for the six months ended June 30, 1998.
Automobile insurance carriers generally pay the non-deductible non-co-pay
portion of the charge, with the remaining balance payable by the individual. The
timing of collection from the individual is partially dependent upon the outcome
and timing of any settlement or judgment of the injury claim. Accordingly, such
receivables typically require a longer period of time to collect compared to the
Company's other receivables, and in the experience of the Company incur a higher
bad debt expense. If the Company were to become less successful in its efforts
in collecting these receivables, the Company's results could be materially and
adversely affected.
 
    Operating costs for the six months ended June 30, 1998 were $61,337,000
compared to $36,284,000 for the six months ended June 30, 1997, an increase of
$25,053,000 or 69%. Primarily, this is due to an increase in operating costs of
$22,718,000 related to centers acquired during 1997. Operating costs at imaging
centers operated by the Company for all of 1997 increased $2,335,000, or 9%, to
$28,524,000 for the six months ended June 30, 1998 from $26,189,000 for the six
months ended June 30, 1997, primarily as a result of increased payroll costs.
 
                                       20
<PAGE>
    Center operating margins, which represent net service revenue less imaging
center operating costs as a percent of net revenue, decreased for the six months
ended June 30, 1998 to 35% from 44% for the six months ended June 30, 1997, due
primarily to higher contractual allowances and generally higher payroll and
administrative costs.
 
    The provision for uncollectible accounts receivable for the six months ended
June 30, 1998 was $7,307,000, an increase of $3,554,000 from six months ended
1997 provision of $3,753,000. The Company's provision for uncollectible accounts
receivable for the six months ended 1998 was 8% of related net service revenues,
compared to the first six months of 1997, which represented 6% of related net
service revenues. The increase in the provision for uncollectible accounts
receivable, as a percentage of net service revenues, was due to an increase in
the estimated rate of bad debts, primarily related to personal injury claim
receivables. If and to the extent that personal injury claim receivables decline
as a percentage of total net service revenues over time, and provided the
Company improves its cash collections of outstanding accounts receivables on an
ongoing basis, this provision should fall below 8% of net service revenues in
the future. Although outstanding accounts receivables increased during the
second quarter of 1998, cash collections from mid-June through early August of
this year have improved and, during this period, outstanding accounts receivable
has decreased slightly.
 
    Corporate general and administrative expense for the six months ended June
30, 1998 was $5,815,000, an increase of $3,126,000 from the $2,689,000 recorded
for the six months ended June 30, 1997. This increase was primarily due to
higher payroll and related costs as a result of the expanded business
development activities and the resulting growth experienced during 1997.
 
    Results for the six months ended June 30, 1998 and 1997 include non-cash
charges of $228,000 and $2,305,000, respectively, for compensation expense
resulting from stock options granted in 1996 and early 1997 that were approved
by the Company's stockholders in May 1997. Such compensation expense represents
the difference between the exercise price of the options and the market price of
the Company Common Stock on the date of plan approval, attributable to vested
shares.
 
    Depreciation and amortization expense for the first six months of 1998 was
$12,635,000 compared to $7,079,000 for the first six months of 1997, or an
increase of $5,556,000 attributable almost entirely to the Company's Diagnostic
Imaging business. The increase was due primarily to higher equipment
depreciation resulting from 1997 acquisitions and increased goodwill
amortization.
 
    During the six months ended June 30, 1998, the Company recorded $5,400,000
of unusual charges consisting of (i) $3,467,000 ($1,194,000 of which was a
non-cash charge related to the issuance of 117,000 Common Stock warrants) for
penalties associated with delays in the registration of the Company's Common
Stock issued in connection with acquisitions or issuable upon conversion of
convertible preferred stock, (ii) $713,000 for the estimated net costs
associated with the resolution of the shareholder and employee lawsuits, (iii)
$883,000 for costs associated with the investigation of related party
transactions and (iv) $337,000 for management termination benefits and related
costs.
 
    The Company could incur a substantial additional amount of unusual charges
during the remainder of 1998 depending upon the outcome of current negotiations
regarding penalties associated with the failure to register the Company's Common
Stock and waivers or amendments of the financial covenants under its Senior
Notes, and the outcome of certain litigation.
 
    Net interest expense for the six months ended June 30, 1998 was $6,912,000
as compared to $2,733,000 for the six months ended June 30, 1997, an increase of
$4,179,000. This increase was primarily attributable to higher outstanding debt,
including the issuance of $78,000,000 of Senior Notes during 1997, notes payable
of $36,505,000 and capital lease obligations totaling $26,612,000 assumed in
connection with the Company's 1997 acquisitions.

    The Company's income for the six months ended June 30, 1998 was decreased by
$643,000 attributable to minority interests, as compared to an increase in the
Company's income of $193,000 for the six months ended June 30, 1997.
 
    The provision for income taxes for the six months ended June 30, 1998
decreased $3,777,000 to $301,000 as compared to $4,078,000 for the comparable
period last year. The provision for income taxes for the six months ended June
30, 1998 consists entirely of estimated state income taxes. During the first six
months of 1998, a benefit for income taxes has not been recorded due to the
uncertainty regarding the recognition of the full amount of the Company's
deferred tax assets.
 
    The Company's net loss from continuing operations for the six months ended
June 30, 1998 was $6,930,000 compared to net income from continuing operations
for the six months ended June 30, 1997 of $5,990,000.
 
    The net loss applicable to common stockholders (used in computing loss per
common share) in the first half of 1998 includes charges of $274,000 as a result
of the accretion of the Company's preferred stock.
 
    In July 1998, the Company decided to sell or close approximately eight
imaging centers. These centers will be sold or closed during the third and
fourth quarters of 1998. In most cases, the Company decided to sell or close
these centers due to general competitive pressures and their close proximity to
other imaging centers of the Company which have more advanced imaging equipment.
The Company expects to incur a charge of between $3,000,000 and $4,000,000
during the third quarter of 1998 related to these imaging centers. Such charge
will consist of (i) the write-off of fixed assets and other assets of between
$2,000,000 and $2,600,000 and (ii) reserve for costs to exit facility and
equipment leases of between $1,000,000 and $1,400,000.
 
    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    For the year ended December 31, 1997, the Company's net service revenues
increased $79,650,000, or 123%, to $144,412,000 in 1997 from $64,762,000 in
1996, due primarily to revenues of $60,849,000 contributed by centers acquired
during 1997. Revenues at imaging centers acquired during 1996 increased
$20,585,000, or 93%, to $42,617,000 in 1997 from $22,032,000 in 1996 primarily
as a result of the timing of the 1996 acquisitions, partially offset by an
increase of $5,896,000 in the estimated provision for uncollectible amounts
related to Type III centers. Revenues at imaging centers that were operated by
the Company for all of 1997 and 1996 decreased $1,784,000, or 4%, to $40,946,000
in 1997 from $42,730,000 in 1996, primarily as a result of higher contractual
allowances in 1997 and relatively constant procedure volumes.
 
    Revenues in 1997 were adversely affected by higher contractual allowance
estimates, including a component related to the ultimate collectibility of
amounts related to the Company's Type III revenue. These contractual allowance
estimates are largely dependent upon reimbursement rates from third party
payors, including Medicare, Medicaid and managed care providers. Management
believes that the Company's overall reimbursement rates will continue to
gradually decline for some period of time, due to factors such as the expansion
of managed care organizations and continued national healthcare reform efforts.
The Company will endeavor to mitigate the impact of any decline in reimbursement
rates by decreasing costs and increasing referral volume. If the rate of decline
in reimbursement rates were to increase materially, or if the Company is
unsuccessful in reducing its costs or increasing its volume, the Company's
results could be materially and adversely affected.
 
    Revenue derived from personal injury claims, mainly involving automobile
accidents, represented approximately 24% of net service revenues for 1997.
Automobile insurance carriers generally pay the non-deductible non-co-pay
portion of the charge, with the remaining balance payable by the individual. The
timing of collection from the individual is partially dependent upon the outcome
and timing of any settlement or judgment of the injury claim. Accordingly, such
receivables typically require a longer period of time to collect compared to the
Company's other receivables, and in the experience of the Company
 
                                       22
<PAGE>
incur a higher bad debt expense. If the Company were to become less successful
in its efforts in collecting these receivables, the Company's results could be
materially and adversely affected.
 
    Operating costs increased $54,408,000, or 156%, to $89,234,000 in 1997 from
$34,826,000 in 1996, due primarily to operating costs of $35,079,000 related to
centers acquired during 1997. Operating costs at imaging centers acquired during
1996 increased $18,155,000, or 149%, to $30,325,000 in 1997 from $12,170,000 in
1996, primarily as a result of the timing of the 1996 acquisitions. Operating
costs at imaging centers that were operated by the Company for all of 1997 and
1996 increased $2,166,000, or 10%, to $23,830,000 in 1997 from $21,664,000 in
1996, primarily as a result of higher payroll and related costs.
 
    Center operating margins, which represent net service revenue less imaging
center operating costs as a percent of net revenue, decreased in 1997 to 38%
from 46% in 1996 due primarily to higher contractual allowance estimates,
including a component related to the ultimate collectibility of amounts related
to the Company's Type III revenue, as described above, and generally higher
costs.
 
    The provision for uncollectible accounts receivable in 1997 was $20,364,000,
or 14% of related net service revenues, compared to the 1996 provision of
$4,705,000 or 7% of related net service revenues. The increase in the provision
for uncollectible accounts receivable was due to the deterioration during 1997
in the aging of the Company's accounts receivable and a reassessment by the
Company of its expected future collections based upon 1997 collection activity,
including analyzing collection experience of its personal injury receivables.
Management believes that the deterioration in the aging of accounts receivable
occurred primarily during the second half of 1997 and was the result of the
Company's substantial acquisition activity in 1997 and the delay in promptly
integrating the billing and collection activities with respect to such
acquisitions. In addition, the Company was without a permanent President and
Chief Financial Officer from October 1997 through February 1998, which allowed
the aging of accounts receivable to continue to worsen since management
resources were not directed at improving billing and collections. During the
fourth quarter of 1997, as the age of the specific bills lengthened, the ability
to research and pursue the old receivables worsened and hence it was determined
that a reserve was required for a substantial number of these older receivables.
Management does not expect further deterioration to occur in 1998 although that
will depend on actual collections performance. Accounts receivable before
allowances for uncollectibles aged over one-year increased to $21,485,000, or
25% of total receivables in 1997, from $7,016,000, or 14% of total receivables
in 1996.
 
    Management expects its provision for uncollectible accounts receivable as a
percentage of revenues to approximate 8% for 1998. An additional reserve of
approximately 1% of net imaging revenues for uncollectible patient and third
party payors related to the Company's Type III centers is expected to be
reflected as a reduction in net revenues for 1998.
 
    Corporate general and administrative expense in 1997 was $12,157,000, an
increase of $7,590,000 from the $4,567,000 recorded in 1996. This increase was
primarily due to higher payroll and related costs as a result of the expanded
business development activities and the resulting growth experienced during the
year. In March 1998, the Company announced a workforce reduction and follow-on
attrition program that is expected to result in reduced payroll costs of
approximately $5,000,000 per annum from the levels of the fourth quarter of
1997. This reduction in workforce is not expected to adversely impact the
ability of the Company to generate future revenue.
 
    During 1997, the Company recorded $2,536,000 of stock-option based
compensation expense. This non-cash charge was related to stock option grants to
employees and directors during 1996 and early 1997 that were subsequently
approved by the Company's stockholders in May, 1997.
 
    Depreciation and amortization expense in 1997 was $18,733,080, compared to
$6,964,000 in 1996, or an increase of $11,769,000 due primarily to higher
equipment depreciation of $6,585,000 resulting from 1997 acquisitions and
increased goodwill amortization of $4,638,000.
 
                                       23
<PAGE>
    During 1997, the Company recorded a $12,962,000 loss from the impairment of
goodwill and other long-lived assets. This loss consists of the write-off of
goodwill of $10,425,000, covenants not to compete of $118,000 and fixed assets
of $2,419,000. The write-down of fixed assets primarily relates to imaging
equipment. Substantially all of the impairment relates to eight of the Company's
diagnostic imaging centers which were under performing. The Company has recorded
impairment losses for these centers because the sum of the expected future cash
flows, determined based on an assumed continuation of current operating methods
and structures, does not cover the carrying value of the related long-lived
assets. The operating performance of these centers declined during 1997 due
primarily to declines in referrals and the Company did not believe that these
centers would materially improve in the future.
 
    During 1997, the Company also recorded $9,723,000 of other unusual charges
consisting of (i) $3,256,000 for the estimated net costs associated with the
resolution of the shareholder and employee lawsuits, (ii) $2,243,000 for higher
than normal professional fees, (iii) $2,169,000 ($2,051,000 of which was a
non-cash charge related to the issuance of 817,000 common stock warrants) for
penalties associated with delays in the registration of the Company's common
stock issued in connection with acquisitions or issuable upon conversion of
convertible preferred stock, (iv) $1,150,000 for the loss on investment related
to a potential acquisition not consummated, (v) $469,000 for costs associated
with the investigation of related party transactions and (vi) $436,000 for
management termination benefits and related costs.
 
    The Company expects to incur additional unusual charges of at least
$4,500,000 during 1998 primarily related to the estimated net costs associated
with the resolution of the shareholder and employee lawsuits, penalties
associated with delays in the registration of the Company's Common Stock, and
costs associated with the investigation of related party transactions which was
concluded in April 1998. Such additional amounts could be substantially higher
depending upon the outcome of current negotiations regarding penalties
associated with the failure to register the Company's common stock and the
outcome of certain litigation.
 
    Net interest expense for 1997 was $8,814,000 as compared to $2,834,000 for
1996, an increase of $5,980,000. This increase was primarily attributable to
higher outstanding debt, including the issuance of $78,000,000 of Senior Notes
during 1997, notes payable of $36,505,000 and capital lease obligations totaling
$26,612,000 assumed in connection with the Company's acquisitions.
 
    The Company's earnings in 1997 were reduced by $636,000 attributable to
minority interests, as compared to $308,000 in 1996. The increase of $328,000 is
primarily due to the acquisition of entities during 1997 that operate limited
partnerships with minority holdings.
 
    The provision for income taxes in 1997 was $1,221,000, as compared to
$3,575,000 in 1996. During 1997, the income tax benefit calculated based upon
the Company's pre-tax loss was reduced by an income tax valuation allowance of
$10,700,000. This valuation allowance was recorded due to uncertainty regarding
the realization of the full amount of the Company's net deferred income tax
assets.
 
    The Company's net loss from continuing operations for 1997 was $31,968,000
compared to net income from continuing operations for 1996 of $6,983,000.
 
    The net loss applicable to common stockholders (used in computing loss per
common share) in 1997 includes charges of $1,938,000 related to Common Stock
subject to redemption and convertible preferred stock. These charges relate to
price protection agreements provided in connection with the Company's 1997
acquisitions of $1,696,000 and the accretion of the Company's preferred stock of
$242,000.
 
    YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    For the year ended December 31, 1996, net service revenues amounted to
$64,762,000 versus $35,860,000 for the year ended December 31, 1995, an increase
of $28,902,000 or 80.6%. Management fee and use revenues for diagnostic imaging
services increased $8,270,000 from $31,174,000 for the year ended December 31,
1995 to $39,445,000 for the year ended December 31, 1996. This increase is
primarily
 
                                       24
<PAGE>
attributable to an increase of $1,326,000 (4.5%) at centers which were included
in revenue for all of 1996 and 1995; $2,752,000 (169%) in revenue at a center
acquired during 1995 and $4,192,000 of revenue contributed by imaging centers
acquired during 1996.
 
    Diagnostic imaging patient service revenues increased $20,631,000 for the
year ended December 31, 1996 to $25,317,000 from $4,686,000 for the year ended
December 31, 1995. This increase is attributable to an increase of $615,000
(19%) at centers which were included in revenue for all of 1995 and 1996;
$2,670,000 (183%) at centers acquired during 1995 and; $22,032,000 of revenue
was contributed by centers acquired during 1996.
 
    Technical services payroll and related costs for the year ended December 31,
1996 amounted to $10,836,000 compared to $6,815,000 for the year ended December
31, 1995, an increase of $4,021,000 or 59%.
 
    Medical supplies amounted to $4,223,000 for the year ended December 31, 1996
as compared to $2,439,000 for the year ended December 31, 1995, an increase of
$1,784,000 or 73%. Of this increase $1,725,000 or 97% is attributable to centers
acquired during 1995 and 1996.
 
    For the year ended December 31, 1996 diagnostic equipment maintenance
increased $1,627,000 or 99% to $3,274,000 from $1,647,000 for the year ended
December 31, 1995. This increase is primarily due to centers acquired during
1995 and 1996.
 
    Independent contractor fees amounted to $1,202,000 for the year ended
December 31, 1996 as compared to $437,000, for the year ended 1995. This
increase of $765,000 or 175% is attributable to the Type II (see Note 1) centers
acquired during 1995 and 1996.
 
    Administrative costs which include facilities rent, marketing costs and
personnel costs of employees whose activities relate to the operations of
multiple centers increased approximately $6,685,000 or 127% from $5,252,000 for
the year ended December 31, 1995 to $11,937,000. This increase is primarily due
to costs incurred at imaging centers acquired during 1995 and 1996.
 
    Other costs increased by $1,924,000 or 134% for the year ended December 31,
1996 to $3,354,000 as compared to $1,430,000 in the prior year primarily due to
an increase in accounting, legal and professional fees for the centers.
 
    Provision for uncollectible accounts receivable increased $1,327,000 or 39%
from $3,378,000 from the year ended December 31, 1995 to $4,705,000 for the year
ended December 31, 1996. The 1996 provision for uncollectible accounts consists
of 7.3% of revenue as compared to 9.4% of revenue in 1995. The decrease in the
provision for uncollectible accounts receivable as a percentage of revenues is
due to acquired companies having a more favorable collection experience due to
differences in payor mix.
 
    Corporate general and administrative expense increased by $1,573,000 or 53%
from $2,994,000 for the year ended December 31, 1995 to $4,567,000 for the year
ended December 31, 1996. This increase is primarily due to the expanded business
development activities and the resulting growth experienced during the year,
particularly following the acquisition of NMR of America, Inc. ("NMR").
 
    Depreciation and amortization expense was $6,964,000 for the year ended
December 31, 1996 compared to $4,274,000 for the year ended December 31, 1995 or
an increase of $2,690,000 or 63% due primarily to depreciation expense relating
to acquired assets and increased goodwill amortization incurred in connection
with such acquisitions.
 
    Interest expense for the year ended December 31, 1996 was $2,834,000 as
compared to $1,829,000 for the prior year, an increase of $1,005,000 or 55%.
This increase is primarily attributable to an increase in interest on
convertible debentures and lines of credit outstanding during 1996 of $646,000
and increases in interest on debt assumed in acquisitions during 1996 totaling
$764,000 offset by decreases in interest expense relating to scheduled
reductions in outstanding principal balances.
 
                                       25
<PAGE>
    Minority interest amounted to $308,000 for the year ended December 31, 1996
as compared to ($124,000) for the year ended December 31, 1995. The increase of
$432,000 or 348.4% is attributable to increased profitability at the Company's
St. Petersburg, Florida and Yonkers, New York facilities ($383,000) and the
acquisition of the NMR facilities ($49,000).
 
    The provisions for income taxes increased $2,332,000 or 188% for the year
ended December 31, 1996 from $1,243,000 to $3,575,000. This increase is
attributable to the increased profitability of the Company's existing and
acquired businesses during 1996 and an increase in the Company's effective
income tax rate. The Company's provision for income taxes resulted in effective
tax rates of 33.9% in 1996 and 22.4% in 1995, respectively.
 
    The 1996 provision was higher than the statutory rate primarily due to state
and local income taxes, net of the Federal tax effect (6.3%), the impact on
non-deductible goodwill (1.8%) and meals and entertainment, offset by other
items amounting to (8.2%). In 1995, the effective tax rate was lower than the
statutory rate primarily due to a reduction in the deferred tax asset valuation
allowance (27.7%) offset by other items amounting to 16.3%.
 
    For the reasons described above, the Company's net income from continuing
operations for the year ended December 31, 1996 increased $2,737,000 or 64.5%
from $4,246,000 for the year ended December 31, 1995 to $6,983,000.
 
STARMED SALE
 
    On August 18, 1998, the Company sold the stock of StarMed to RehabCare
Group, Inc. for gross proceeds of $33,000,000. Due to the StarMed Sale, the
results of operations of StarMed are herein reflected in the Company's
Consolidated Statements of Operations as discontinued operations.
 
    Net cash proceeds from the StarMed Sale were used as follows: (i)
$13,786,000 to repay StarMed's outstanding third-party debt (in accordance with
the terms of sale) (ii) $2,000,000 was placed in escrow to be available, for a
specified period of time, to fund indemnification obligations that may be
incurred by the Company (part or all of this amount may be payable to the
Company over time) and (iii) an additional $2,000,000 was placed into escrow to
be applied as a partial repayment of the Company's $78,000,000 of Senior Notes.
The remaining net proceeds of approximately $13,400,000 increased the Company's
consolidated cash balances. For accounting purposes, a pretax gain from the
StarMed Sale of approximately $5,000,000 is expected to be reported in the third
quarter of 1998.
 
RESULTS OF DISCONTINUED OPERATIONS
 
    SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997
 
    Net service revenues for StarMed increased to $40,307,000 for the six months
ended June 30, 1998 from $25,947,000 for the six months ended June 30, 1997, an
increase of $14,360,000 or 55%. Internal growth in the staffing business,
consisting primarily of the opening of new Per Diem division offices, accounted
for $11,483,000 of the increase in revenues. Revenues at Per Diem division
offices acquired during 1997 accounted for $2,877,000 of the increase.
 
    Operating costs for StarMed for the six months ended June 30, 1998 were
$32,197,000 compared to $21,148,000 for the six months ended June 30, 1997, an
increase of $11,049,000 or 52%. Internal growth in the staffing business
accounted for $8,940,000 of the increase in operating costs. Increased costs at
Per Diem division offices acquired during 1997 accounted for $2,109,000 of the
additional operating costs.
 
    Net earnings related to StarMed increased to $1,341,000 for the six months
ended June 30, 1998 from $395,000 for the six months ended June 30, 1997.

    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    Net service revenues for StarMed increased to $57,974,000 in 1997 from
$29,023,000 in 1996, an increase of $28,951,000 or 100%. Internal growth in the
staffing business, consisting primarily of the opening of new per diem offices,
accounted for $5,442,000 of the increase in revenues. Increased revenues at per
diem offices opened or acquired during 1996 accounted for $16,861,000 of
revenues and revenues of $6,648,000 were contributed by per diem offices
acquired during 1997.
 
    Operating costs for StarMed in 1997 were $46,831,000 compared to $24,238,000
for the year ended December 31, 1996, an increase of $22,593,000 or 93%.
Internal growth in the staffing business, accounted for $4,143,000 of the
increase in operating costs. Increased costs at per diem offices opened or
acquired during 1996 accounted for $11,812,000 of the higher operating costs and
operating costs of $5,646,000 were contributed by per diem offices acquired
during 1997.
 
    Center operating margins for StarMed increased in 1997 to 19% from 16% due
primarily to improved profitability of per diem offices opened or acquired prior
to 1997.
 
    Net earnings related to StarMed increased to $729,000 in 1997 from $271,000
in 1996.
 
    YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    StarMed revenues increased $12,890,000 (80.3%) primarily due to internal
growth and acquisitions. Internal growth in the staffing segment consisting of
the opening of new per diem offices accounted for approximately $3,200,000 of
the increase in staffing revenue. Increased revenues at per diem offices opened
during 1995, related primarily to improved volume as these offices matured from
their start up phase, accounted for approximately $3,400,000 of the increase in
staffing revenues. Per diem staffing businesses acquired during 1996 contributed
approximately $6,300,000 in revenues during the year.
 
    Technical services payroll and related costs for StarMed for the year ended
December 31, 1996 amounted to $24,238,000 compared to $12,711,000 for the year
ended December 31, 1995, an increase of $11,527,000 or 91%. Of this increase
$6,569,000 or 42% is attributable to the opening of new per Diem offices and the
staffing acquisitions and $2,622,000 increase is due to the maturation of per
diem offices opened in 1995.
 
    Net earnings related to StarMed were $271,000 for 1996, as compared to a net
loss of $103,000 for 1995.
 
    Net loss related to the Company's discontinued maternity apparel subsidiary
was $2,453,000 in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During the six months ended June 30, 1998, the Company's primary source of
cash flow was from reductions in the Company's cash balances of $9,113,000 and
borrowings under the Company's lines of credit of $6,847,000. The primary use of
cash was the repayment of principal amount of capital lease obligations and
notes and mortgages payable of $10,550,000, and repurchase of Common Stock
subject to redemption as a result of the exercise of puts provided by the
Company in connection with 1997 acquisitions of $3,311,000. Operating activities
provided cash of $1,101,000 during the six months ended June 30, 1998. Cash flow
from operating activities was adversely effected by an increase of $8,874,000 in
accounts receivable, net of allowance for bad debts. The increase in accounts
receivable is the result of difficulties experienced in integrating the billing
and collection systems of the centers acquired during 1997. By July of 1998, the
Company completed the planned conversion of over 77% of its centers to the
Company's proprietary radiology information system, ICIS, and commenced a
restructuring of its collection efforts for the purpose of ultimately
consolidating all collection activities within four or more regional collection
offices. The restructuring is in response to the need to improve overall
collection results and controls. The Company expects that these efforts will
result in an improved collection rate of accounts
 
                                       27
<PAGE>
receivable and cash flows. From mid-June through early August of this year, cash
collections have improved and, during this period, outstanding accounts
receivable has decreased slightly.
 
    During the six months ended June 30, 1997, the Company's primary source of
cash flow was from financing activities, as a result of net proceeds from the
Senior Notes of $77,113,000. The primary use of cash was to fund acquisitions
which totaled approximately $38,732,000 and to fund the repayment of certain
notes and capital lease obligations of $28,955,000. Operating activities
provided cash of $2,935,000 during the first half of 1997.
 
    During 1997, the Company's primary source of cash flow was from financing
activities, largely as a result of net proceeds from the Senior Notes of
$76,523,000, net proceeds from the issuance of convertible preferred stock of
$16,965,000, and other financing activities. The primary use of cash was to fund
acquisitions which totaled $73,121,000 and to fund the repayment of certain
notes and capital lease obligations of $13,764,000. Operating activities
resulted in a net use of cash of $5,322,000 during 1997 due primarily to
increases in accounts receivable.
 
    Net cash provided by operating activities for 1996 and 1995 was $1,450,000
and $2,335,000, respectively, representing a decrease of $885,000 in 1996. The
decrease was due primarily to a large increase in accounts receivable and
certain other assets which relate primarily to the Company's expansion
activities offset by increases in net income, non-cash charges and other
liabilities. In 1996, net cash used in investing activities totaled $16,703,000
which includes (i) $8,569,000 expended for the purchase of diagnostic imaging
centers, offset by $2,157,000 of cash acquired in the acquisition of NMR, (ii)
$2,314,000 for the purchase of Per Diem staffing businesses and (iii) $184,000
for the purchase of limited partnership interests. During 1996, the Company
purchased $6,137,000 of investments, $4,500,000 of these investments were
subsequently set aside (restricted) pursuant to the terms of a letter of credit
issued in connection with an acquisition. An additional $600,000 in cash was set
aside (restricted) pursuant to a letter of credit issued in conjunction with a
consulting agreement to which the Company is a party. The Company expended
$1,070,000 in 1996 for medical diagnostic and office equipment. Financing
activities provided $27,110,000 in cash during the year ended December 31, 1996,
which consisted of net proceeds of $25,164,000 received through a public
offering of the Company's Common Stock, $6,533,000 of net proceeds from the
issuance of subordinated debentures, $1,229,000 proceeds from borrowings during
the year (used to purchase equipment for the imaging centers), $2,022,000
realized from the exercise of stock options and warrants, offset by $7,773,000
utilized for the repayment of debt and capital lease obligations and $64,000
used to purchase shares of the Company's Common Stock.
 
    The Company has never declared a dividend on its Common Stock and under the
Company's Senior Note agreement, the payments of such dividends is not
permitted.
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company is currently in default of certain financial
covenants under the agreements for its $78,000,000 of Senior Notes. The
financial covenant defaults under the Senior Note agreements entitle the lenders
to exercise certain remedies including acceleration of repayment. In addition,
certain medical equipment notes, and operating and capital leases of the
Company, aggregating $14,575,000 at June 30, 1998 (the "Cross-Default Debt"),
contain provisions which allow the creditors or lessors to accelerate their debt
or terminate their leases and seek certain other remedies if the Company is in
default under the terms of agreements such as the Senior Notes. In the event
that the Senior Note lenders or the holders of the Cross Default Debt elect to
exercise their right to accelerate the obligations under the Senior Notes or the
other loans and leases, such acceleration would have a material adverse effect
on the Company, its operations and its financial condition. Furthermore, if such
obligations were to be accelerated, in whole or in part, there can be no
assurance that the Company would be successful in identifying or consummating
financing necessary to satisfy the obligations which would become immediately
due and payable. As a result of the uncertainty related to the defaults and
corresponding remedies described above, the Senior Notes and the Cross Default
Debt were shown as current liabilities on the Company's Consolidated Balance
Sheets at
 
                                       28
<PAGE>
June 30, 1998 and December 31, 1997. Accordingly, the Company had a deficit in
working capital of $55,892,000 at June 30, 1998. These matters raise substantial
doubt about the Company's ability to continue as a going concern. The report of
the Company's independent auditors, Ernst & Young LLP, on the consolidated
financial statements of the Company for the year ended December 31, 1997
contains an explanatory paragraph with respect to the issues that raise
substantial doubt about the Company's ability to continue as a going concern
mentioned in Note 2 to the Company's consolidated financial statements. The
financial statements do not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    Management has reached an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications. Under the terms of the agreement in principle, the Senior Note
lenders have agreed to waive all existing covenant defaults and to modify the
financial covenants applicable over the remaining term of the Senior Notes. In
consideration for these waivers and covenant modifications, the Company has
agreed to increase the effective blended interest rate on the Senior Notes from
7.87% to 9.00%, and issue to the Senior Note lenders warrants to acquire 375,000
shares of the Company's Common Stock at an exercise price of $7.67 per common
share. In addition, the Company has agreed to prepay $2,000,000 of principal
outstanding on the Senior Notes (without premium) and to pay a fee to the Senior
Note lenders of $500,000. The agreement in principle is subject to the execution
of definitive documents, which are expected to be completed during September
1998.
 
    In addition to reaching an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications, the Company has taken various actions in response to this
situation, including the following: (i) it effected a workforce reduction in
March 1998 aimed at reducing the Company's overall expense levels by
approximately $5,000,000 per annum and (ii) sold the Company's temporary
healthcare staffing business, StarMed, for $33,000,000 in August 1998. Upon
execution of the definitive documents with respect to the Senior Notes, the
Senior Notes and the Cross Default Debt will no longer be in default and will be
shown as long-term debt beginning with the September 30, 1998 Consolidated
Balance Sheet.
 
    The Company has a working capital deficit of $55,892,000 at June 30, 1998
compared to a working capital deficit of $58,174,000 at December 31, 1997. The
deficit in both periods is primarily due to $78,000,000 of Senior Notes due 2001
through 2005 and other debt and capital leases shown as current liabilities as a
result of financial covenant defaults under such agreements.
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration, the Company
granted rights to have such shares registered for resale pursuant to the federal
securities laws. In certain of such acquisitions, the Company has granted
specific remedies to the sellers in the event that the registration statement
covering the relevant shares is not declared effective by the Securities and
Exchange Commission within an agreed-upon period of time, including the right to
require the Company to repurchase the shares issued to such seller. In the event
the Company is unable to register such shares by the required dates, the Company
would become obligated to repurchase the shares issued in connection with such
acquisition. As of June 30, 1998 and December 31, 1997, the Company had
reflected $5,509,000 and $9,734,000, respectively, of Common Stock subject to
redemption on its Consolidated Balance Sheet related to shares that the Company
may be required to repurchase. During the first six months, ended June 30, 1998,
the Company paid $3,311,000 to sellers who exercised their rights to have shares
of Common Stock repurchased. The Company expects to pay an additional $5,509,000
during the remainder of 1998 ($3,696,000 of which was due and payable on June 3,
1998 (the "June 1998 Repurchase Obligation") but has not been paid by the
Company) in connection with the settlement of certain repurchase obligations of
the Company subject, under certain circumstances, to the consent of the Senior
Note holders. With respect to the June 1998 Repurchase Obligation which
 
                                       29
<PAGE>
remains due and payable, the Company is in discussions with the sellers to whom
such obligations are owed and the Senior Note lenders regarding the timing and
satisfaction of the June 1998 Repurchase Obligation.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay to the sellers (in
additional shares and/or cash) an amount equal to the shortfall in the value of
the issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement (referred
to as "Price Protection"). Any such Price Protection payments will be charged to
stockholders' equity. Based upon the closing sales price of the Company's Common
Stock on September 1, 1998 ($4.00 per share), such shortfall would be
approximately $3,351,000, excluding Price Protection obligations related to the
shares which have repurchase obligations, referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differ for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both. Contingent consideration associated
with acquisitions is recorded as additional purchase price when resolved.
 
    Although the Company has the option, in certain cases, to pay certain of
such amounts in shares of Common Stock, payment of significant cash funds to
sellers in the event such remedies or earnout provisions are triggered could
have a material adverse effect on the Company's cash flow and financial
condition. In addition, the Company may be required to finance all or a portion
of any such cash payments from third-party sources. No assurance can be given
that such capital will be available on terms acceptable to the Company. In
addition, the issuance by the Company of shares of Common Stock in payment of
any such owed amounts could be dilutive to the Company's stockholders.
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement, dated July 21, 1997, and the Registration Rights Agreement dated July
21, 1997, as amended, between the Company and RGC International, LDC ("RGC")
(hereinafter referred to as the "RGC Agreements"), the Company issued 18,000
shares of Series C Convertible Preferred Stock, $1,000 stated value per share
(the "Series C Preferred Stock") to RGC. Under the RGC Agreements, the Company
was required to use its best efforts to include the shares of Common Stock
issuable upon conversion of the Series C Preferred Stock (the "RGC Conversion
Shares") in an effective Registration Statement on Form S-3 not later than
October 1997. As amended, the RGC Agreements provide for monthly penalties ("RGC
Registration Penalties") in the event that the Company failed to register the
Conversion Shares prior to October 1997 with such penalties continuing until
July 23, 1998.
 
    On June 18, 1998 2,500 shares of Series C Preferred Stock were converted
into 373,220 shares of Common Stock. Accordingly, as of June 30, 1998, 15,500
shares of the Company's Series C Preferred Stock were issued and outstanding.
Each share of the Series C Preferred Stock is convertible into such number of
shares of Common Stock as is determined by dividing the stated value ($1,000) of
each share of Series C Preferred Stock plus 3% per annum from the closing date
to the conversion date by the lesser of (i) $62.10 or (ii) the average of the
daily closing bid prices for the Common Stock for the (5) five consecutive
trading days ending five (5) trading days prior to the date of conversion.
 
    As a result of the Company's continued failure to register the RGC
Conversion Shares, the Company: (i) issued warrants to RGC to acquire 389,000
shares of Common Stock at an exercise prices ranging from $34.86 to $38.85 per
share, subject to reset in November 1998 (such warrants having an estimated
value, for accounting purposes, of $3,245,000); and (ii) issued interest bearing
promissory notes (the "RGC Penalty
 
                                       30
<PAGE>
Notes") in the aggregate principal amount of $2,450,000 due October 15, 1998.
The principal amount of and interest accrued on the RGC Penalty Notes may be
converted, at the option of the Company or RGC in certain circumstances, into
additional shares of Series C Preferred Stock or Common Stock. Pursuant to an
amendment to the RGC Agreements entered into June 1998, the Company will no
longer incur any monthly penalties for failure to register the RGC Conversion
Shares following July 23, 1998. However, if the RGC Conversion Shares are not
registered as of September 15, 1998 (the Company is currently in discussions
with RGC to extend such date), RGC may demand a one-time penalty of $1,550,000
(the "September 1998 Penalty"), payable, at the option of RGC, in cash or
additional shares of Common Stock. There can be no assurance that the Company
will be able to register the RGC Conversion Shares by such date, or any extended
date, or that the Company will be able to pay the RGC Penalty Notes when due or
the September 1998 Penalty, if such payment becomes due. Purchasers of Common
Stock could therefore experience substantial dilution upon conversion of the
Series C Preferred Stock and the RGC Penalty Notes and the exercise of such
warrants. The shares of Series C Preferred Stock are not registered and may be
sold only if registered under the Act or sold in accordance with an applicable
exemption from registration, such as Rule 144.
 
    In addition to matters discussed above, the Company is subject to litigation
that may require additional future cash outlays.
 
    During 1997, the Company incurred substantial debt in connection with
acquisitions of imaging centers. As of June 30, 1998, the Company's debt,
including capitalized lease obligations, totaled $155,369,000. The aggregate
estimated amounts of principal, interest and capital lease obligations due in
each of the years ended December 31, 1998 through 2002 on such debt, including
payments associated with the StarMed Sale, is $49,125,000 ($37,980,000 of which
has been paid through August 31, 1998), $25,713,000, $27,647,000, $32,373,000
and $24,177,000, respectively. The Company does not expect to incur significant
additional debt in the near future and expects to rely on its existing cash
balances, of approximately $18,242,000 at August 31, 1998, and its ability to
enter into operating leases to fund expansions and equipment replacement at its
centers.
 
    The Company's sources of liquidity consist of its cash balances and its
ability to enter into operating leases to fund expansions and equipment
replacement at its centers. At June 30, 1998 and December 31, 1997, the
Company's cash and cash equivalents were $14,085,000 and $23,198,000,
respectively. As a result of improvements in the Company's billing and
collection systems, the Company expects its cash flow from operations, including
changes in accounts receivable, to increase from the level achieved in the six
months ending June 30, 1998. Assuming that the Company executes definitive
documents with respect to the Senior Notes consistent with the agreement in
principle, management believes that the positive cash flow from operations, the
Company's existing cash balances, and net cash proceeds from the StarMed Sale
will provide it with sufficient funds available to finance its needs through
1998.
 
    In order to meet one of Nasdaq's alternative listing requirements, the
Company effected a one-for-three reverse stock split of its Common Stock on July
24, 1998. On July 28, 1998, the Nasdaq Qualifications Listing Panel notified the
Company that the Company had complied with Nasdaq's continued listing
qualifications and that the Common Stock would continue to be listed on The
Nasdaq Stock Market. The share data included in this Prospectus has been
adjusted to reflect the impact of the reverse stock split. There can be no
assurance that in the future the Common Stock will meet the continued listing
requirements for The Nasdaq Stock Market.
 
SEASONALITY AND INFLATION
 
    The Company believes that its imaging business is generally unaffected by
seasonality. The impact of inflation and changing prices on the Company has been
primarily limited to salary, medical and film supplies and rent increases and
has not been material to date to the Company's operations. Notwithstanding the
foregoing, general inflationary expectations and growing health care cost
containment pressures in
 
                                       31
<PAGE>
the future may cause the Company not to be able to raise the prices for its
diagnostic imaging procedures by an amount sufficient to offset such negative
effects. While the Company has responded to these concerns in the past by
increasing the volume of its business there can be no assurance that the Company
will be able to increase its volume of business in the future. In addition,
current discussions within the Federal Government regarding national health care
reform are emphasizing containment of health care costs as well as expansion of
the number of eligible parties. The implementation of this reform could have a
material effect on the financial results of the Company.
 
IMPACT OF YEAR 2000 ON COMPANY'S COMPUTER SOFTWARE
 
    The Computer programming code utilized in the Company's financial, billing
and imaging equipment systems were generally written using two digits rather
than four to define the applicable year. As a result, those computer programs
have time-sensitive software that recognizes a date using 00's as the year 1900
rather than the year 2000. This could cause a system failure or miscalculations
resulting in disruptions of operations, including, among other things, a
temporary inability to process transactions, send invoices or engage in other
normal business activities.
 
    The Company has completed an assessment of its material financial and
billing computer systems. The Company is in the process of upgrading these
systems to be Year 2000 compliant and expects to complete this process by late
1998 to early 1999. The cost to be incurred related to Year 2000 compliance for
these systems is currently not expected to be material.
 
    The Company has initiated a program to determine whether the computer
applications of its significant payors and suppliers will be upgraded in a
timely manner. The Company has also initiated a program to determine whether
embedded applications that control certain medical and other equipment will be
affected. The Company has not yet completed these reviews. The nature of the
Company's business is such that any failure to these types of applications may
have a material adverse effect on its business. If the Company determines that
certain of its suppliers will not be year 2000 compliant, then the Company will
endeavor to find alternative suppliers; however, there can be no assurance that
the Company will be able to find alternative suppliers.
 
    Because of the many uncertainties associated with Year 2000 compliance
issues, and because the Company's assessment is necessarily based on information
from third party-vendors, payors and suppliers, there can be no assurance that
the Company's assessment is correct or as to the materiality or effect of any
failure of such assessment to be correct.
 
    Software sold by the Company's wholly-owned subsidiary, Dalcon Technologies,
Inc., is expected to be fully year 2000 compliant in connection with the annual
upgrade planned for late 1998.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    SFAS No. 130, "Reporting Comprehensive Income", requires an entity to report
comprehensive income and its components for fiscal years beginning after
December 15, 1997. This new standard increases financial reporting disclosures,
but will have no impact on the Company's financial position or results of
operations.
 
    Statement Of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use", requires an entity to expense all
software development costs incurred in the preliminary project state training
costs and data conversion costs for fiscal years beginning after December 15,
1998. The Company believes that this statement will not have a material effect
on the Company's accounting for computer software acquisition cost.
 
    Statement Of Position 97-2, "Consolidation of Physicians' Practice
Entities", requires an entity to consolidate Physicians' Practice Entities in
circumstances in which substantial control is exercised by the
 
                                       32

Company. The Company believes that this statement will not have a material
effect on the Company's financial position or results of operations.
 
DISCLOSURE REGARDING FORWARD LOOKING STATEMENTS
 
    Statements contained in this Prospectus that are not historical facts are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. Investors are cautioned that forward-looking
statements are inherently uncertain. Actual performance and results may differ
materially from that projected or suggested herein due to certain risks and
uncertainties including, without limitation: the ability of the Company to
effectively integrate the operations and information systems of businesses
acquired in 1997 and earlier; the ability of the Company to generate net
positive cash flows from operations; the payment timing and ultimate
collectibility of accounts receivable (including purchased accounts receivable)
from different payor groups (including Personal Injury-type); the economic
impact of involuntary share repurchases and other payments (including price
protection payments and penalty payments) caused by the delay in the
effectiveness of the Company's Registration Statement of which this Prospectus
is a part and by the recent decline in the Company's share price; the ability of
the Company and its Senior Note Lenders to finalize and execute definitive
documents, in general, and consistent with their agreement-in-principle, which
cure all existing loan covenant defaults and which modify the financial
covenants applicable over the remaining term of the Senior Notes; the impact of
a changing and increasing mix of managed care and personal injury claim business
on contractual allowance provisions, net revenues and bad debt provisions; the
extent of Medicare reimbursement reductions effected by the Health Care
Financing Administration (HCFA) in line with its recent proposals; the ultimate
economic impact of recent litigation including shareholder and former management
lawsuits against the Company and certain of its Directors; the availability of
debt and/or equity capital, on reasonable terms, to finance operations as needed
and to finance growth; and the effects of federal and state laws and regulations
on the Company's business over time. Additional information concerning certain
risks and uncertainties that could cause actual results to differ materially
from that projected or suggested may be identified from time to time in the
Company's Securities and Exchange Commission filings and the Company's public
announcements.

                                    BUSINESS
 
GENERAL
 
    Medical Resources, Inc. ("Medical Resources" and collectively with its
subsidiaries, affiliated partnerships and joint ventures, the "Company")
specializes in the operation and management of fixed-site outpatient diagnostic
imaging centers, and also provides temporary healthcare staffing services to
acute and sub-acute care facilities. Through its Diagnostic Imaging division,
the Company currently operates 94 outpatient diagnostic imaging centers located
in the Northeast (56), Southeast (24), the Midwest (9) and California (5), and
provides network management services to managed care organizations. The Company
has grown rapidly and has increased the number of diagnostic imaging centers it
operates from 39 at December 31, 1996 to 94 at September 1, 1998. The Company,
through its wholly-owned subsidiary, Dalcon Technologies, Inc. ("Dalcon"), also
develops and markets software products and systems for the diagnostic imaging
industry.
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
Divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold the stock of StarMed
to RehabCare Group, Inc. for $33 million (the "StarMed Sale"). Due to the
StarMed Sale, the results of operations of StarMed are herein reflected in the
Company's Consolidated Statements Of Operations as discontinued operations.
 
    DIAGNOSTIC IMAGING DIVISION.  The Company's diagnostic imaging centers
provide diagnostic imaging services in a comfortable, service-oriented
outpatient environment to patients referred by physicians. At each of its
centers, the Company provides management, administrative, marketing and
technical services, as well as equipment, technologists and facilities, to
physicians who interpret scans performed on patients. Medical services at the
Company's imaging centers are provided by board certified interpreting
physicians, generally radiologists, with whom the Company enters into contracts.
Of the Company's 94 centers, 82 provide magnetic resonance imaging. Many of the
Company's centers also provide some or all of the following services:
computerized tomography, ultrasound, nuclear medicine, general radiology,
fluoroscopy and mammography.
 
    The Company's goal is to become the leading operator of fixed-site
outpatient diagnostic imaging centers in the United States. The number of
outpatient diagnostic imaging centers in the United States is estimated to have
grown from approximately 700 in 1984 to approximately 2,500 as of December 31,
1997. Ownership of fixed-site outpatient diagnostic imaging centers is highly
fragmented, with no dominant national provider. The Company believes that the
environment faced by diagnostic imaging center operators is characterized by an
increased influence of managed care organizations, rising business complexity,
growing control over patient flows by payors, and continued overall
reimbursement pressures, all of which have been and will continue to require
center owners to seek operational efficiencies. In addition, the Company
believes that public and private reforms in the healthcare industry emphasizing
cost containment and accountability will continue to shift the delivery of
imaging services from highly fragmented, individual or small center operators to
companies operating larger multi-modality networks of centers.
 
    The Company intends, over time, to capitalize on the fragmented nature of
the diagnostic imaging center industry through the acquisition of additional
centers. The Company's strategy has also been to seek to expand the scope and
efficiency of its operations at its existing and acquired facilities by: (i)
leveraging the geographic concentration of its centers; (ii) expanding the
imaging services offered by its centers by upgrading existing technology and
adding new modalities; (iii) applying sophisticated operating, financial and
information systems and procedures; (iv) utilizing targeted local marketing
programs; and (v) developing its network management services to address more
fully the needs of managed care organizations.

    Dalcon is a developer and provider of software system applications to
diagnostic imaging center operators. Through its proprietary radiology
information system, ICIS, Dalcon provides the Company's imaging centers, as well
as imaging centers owned and/or operated by third-parties, with information
system development, service and support specifically designed for the
administration and operation of imaging centers, including patient scheduling,
registration, transcription, film tracking, billing, and insurance claim
processing. The Company purchased Dalcon in September 1997. As of June 1998, the
substantial majority of the Company's imaging centers had been fully integrated
and operating on Dalcon's ICIS system. In addition, in February 1998, Dalcon
entered into a multi-year agreement with HealthSouth Corporation, pursuant to
which Dalcon is to install its ICIS information system at all of HealthSouth's
imaging centers not currently using it.
 
    PER DIEM AND TRAVEL NURSING DIVISIONS.  The Company's temporary staffing
business, StarMed, was founded in 1978 and acquired by the Company in August
1994. StarMed's Per Diem staffing division provided registered nurses, licensed
practical nurses, nursing assistants, therapists and medical transcriptionists
on a daily basis to healthcare facilities through 35 offices located in 16
states as of March 31, 1998. StarMed's Travel Nursing division operated from a
central office in Clearwater, Florida and provided registered nurses and
operating room technicians for periods usually ranging from 8 to 26 weeks.
StarMed commenced its Per Diem operations in March 1995 and, since that time, it
had opened 31 offices, acquired 4 staffing companies operating six additional
offices and consolidated the operations of two other offices. Due to the August
1998 sale of StarMed, the results of operations of StarMed are herein reflected
in the Company's Consolidated Statements of Operations as discontinued
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Results of Discontinued Operations."
 
    Medical Resources was incorporated in Delaware in August 1990 and has its
principal executive office at 155 State Street, Hackensack, New Jersey 07601,
telephone number (201) 488-6230. Prior to the Company's incorporation, the
Company's operations, which commenced in 1979, were conducted by corporations
which are now among its subsidiaries.
 
DIAGNOSTIC IMAGING SERVICES INDUSTRY
 
OVERVIEW
 
    Imaging centers have played a vital role in the healthcare delivery system
by offering diagnostic services such as Magnetic Resonance Imaging ("MR"),
Computerized Tomography ("CT"), Ultrasound, Nuclear Medicine, Mammography and
X-ray in an outpatient setting. Diagnostic imaging procedures are used to
diagnose diseases and physical injuries through the use of various imaging
modalities. The use of non-invasive diagnostic imaging has grown rapidly in
recent years because it allows physicians to diagnose quickly and accurately a
wide variety of diseases and injuries without exploratory surgery or other
invasive procedures, which are usually more expensive, risky and potentially
debilitating for patients. In addition, diagnostic imaging is increasingly being
used as a screening tool for preventative care. While conventional X-ray
continues to be the primary imaging modality based on the number of procedures
performed, the use of MR and CT procedures has increased due to their more
sophisticated diagnostic capabilities. The Company believes that utilization
will continue to increase because of the growth in demand for diagnostic imaging
services as well as the introduction of new diagnostic imaging procedures
involving new or existing modalities.
 
EQUIPMENT AND MODALITIES
 
    Diagnostic imaging systems are generally based on the ability of energy
waves to penetrate human tissue and generate images of the body which can be
displayed either on film or on a video monitor. Imaging systems have evolved
from conventional x-rays to the advanced technologies of MR, CT,
 
                                       35

Ultrasound, Nuclear Medicine and Mammography. The principal diagnostic imaging
modalities used by the Company include the following:
 
    MAGNETIC RESONANCE IMAGING.  MR is a sophisticated diagnostic imaging system
that utilizes a strong magnetic field in conjunction with low energy
electromagnetic waves which are processed by a computer to produce high
resolution images of body tissue. A principal element of MR imaging is that the
atoms in various kinds of body tissue behave differently in response to a
magnetic field, enabling the differentiation of internal organs and normal and
diseased tissue. Unlike CT and X-rays, MR does not utilize ionizing radiation
which can cause tissue damage in high doses. As with other diagnostic imaging
technologies, MR is generally non-invasive.
 
    COMPUTERIZED TOMOGRAPHY.  CT is used to detect tumors and other conditions
affecting bones and internal organs. CT provides higher resolution images than
conventional X-rays. In a CT, a computer directs the movement of an X-ray tube
to produce multi-cross sectional images of a particular organ or area of the
body.
 
    ULTRASOUND.  Ultrasound has widespread application, particularly for
procedures in obstetrics, gynecology and cardiology. Ultrasound imaging relies
on the computer-assisted processing of sound waves to develop images of internal
organs and the vascular system. A computer processes sound waves as they are
reflected by body tissue, providing an image that may be viewed immediately on a
computer screen or recorded continuously or in single images for further
interpretation.
 
    NUCLEAR MEDICINE.  Nuclear medicine is used primarily to study anatomic and
metabolic functions. During a nuclear medicine procedure, short lived
radioactive isotopes are administered to the patient by ingestion or injection.
The isotopes release small amounts of radioactivity that can be recorded by a
gamma camera and processed by a computer to produce an image of various
anatomical structures.
 
    GENERAL RADIOLOGY AND FLUOROSCOPY (X-RAY).  The most frequently used type of
imaging equipment in radiology utilizes "X-rays" or ionizing radiation to
penetrate the body and record images on film. Fluoroscopy uses a video viewing
system for real time monitoring of the organs being visualized.
 
    MAMMOGRAPHY.  Mammography is a specialized form of radiology equipment using
low dosage X-rays to visualize breast tissue. It is the primary screening tool
for breast cancer.
 
IMAGING CENTER LOCATION AND OWNERSHIP STRUCTURE
 
    The following table sets forth certain information concerning the imaging
centers operated by the Company. Imaging centers that are not 100% owned by the
Company, through a wholly-owned subsidiary, are typically owned by limited
partnership or other business entities in which a subsidiary of the Company is
the sole general partner or manager. The equity ownership interest shown
includes general and limited partnership interests or other equity interests
owned by the Company. For the centers not wholly owned by the Company, the
Company is generally paid a management fee based on services provided under
management agreements with the imaging center's ownership entity.

    Where it deems it economically attractive, the Company may further increase
its ownership of its non-wholly-owned centers by acquiring additional minority
interests in such centers, but there can be no assurance that the Company will
be successful in so doing. The Company has also added new imaging equipment
modalities to certain centers and plans to continue this strategy in those
situations where the Company believes that such additions are economically
justified.
 
    Each center consists of a waiting/reception area and one room per modality,
dressing rooms, billing/ administration rooms and radiologist interpreting
rooms. The size of the Company's centers generally ranges from 1,500 to 11,400
square feet.
 
GROWTH STRATEGY AT EXISTING AND ACQUIRED CENTERS
 
    LEVERAGING GEOGRAPHIC CONCENTRATION.  The Company has developed clusters of
imaging centers in certain geographic areas that enable it to improve the
utilization of its centers by attracting business from larger referral sources,
such as managed care organizations, due to the Company's ability to meet the
quality, volume and geographical coverage requirements of these payors. The
Company intends, over time, to increase its center concentration in existing
markets to attract additional referrals of this type and to expand into new
geographic areas, through acquisitions, in order to attract additional managed
care and other contracts.
 
    EXPANDING IMAGING SERVICES OFFERED.  The Company expands the imaging
services it offers by upgrading existing technology and adding new modalities at
selected centers. In 1997 and to date in 1998, the Company upgraded technology
and expanded service modalities at 15 centers. The Company's imaging centers
utilize state of the art imaging equipment for which new applications are
continually being developed. New developments and system upgrades frequently
have the ancillary benefit of reducing imaging time and thus increasing capacity
of the centers' imaging equipment. The development and improvement of diagnostic
quality "open" MR systems have expanded the public acceptance and potential
market for MR imaging services. The Company currently operates 32 centers that
provide MR imaging services using "open" systems and the Company plans to expand
this coverage in markets where it believes such expansion is economically
justified.
 
    APPLY SOPHISTICATED OPERATING, FINANCIAL AND INFORMATION SYSTEMS AND
PROCEDURES.  The Company provides management expertise, financial and operating
controls, and capital resources to its centers in an attempt to optimize their
performance. The financial systems and operating procedures of acquired centers
are, over time, integrated with those of the Company. In that regard, as of June
1998 the Company completed the installation of the ICIS system developed by
Dalcon in substantially all of its centers. The ICIS system will enable the
Company to standardize reporting of each center and provide management with
on-line access to its centers nationwide. In addition, the Company is able to
achieve economies of scale and provide cost savings in developing managed care
contracts and negotiating group purchasing of goods and services.
 
    UTILIZE TARGETED LOCALIZED MARKETING.  The Company develops and coordinates
marketing programs which center managers, sales representatives and affiliated
interpreting physicians utilize to establish referral relationships and to
maximize facility usage and reimbursement yield. The Company's marketing
programs emphasize the capabilities of its imaging equipment, the quality and
timeliness of the imaging results and reports, and the high level of patient and
referring physician service.
 
    DEVELOP NETWORK MANAGEMENT SERVICES.  The Company plans to develop and
expand further its network management services business. As a network manager,
the Company enters into contracts with managed care organizations to coordinate
the demand for imaging services and to provide certain administrative functions
related to the delivery of such services. The Company includes certain of its
centers in these networks and believes that the inclusion of these centers in
the networks will increase their
 
                                       39
<PAGE>
utilization. In addition, the Company believes that its network management
services enhance its relationships with managed care organizations and its
ability to enter into additional contracts with such entities.
 
CENTER OPERATIONS AND IMAGING SERVICES PROVIDED BY THE COMPANY
 
    GENERAL.  The Company's diagnostic imaging centers provide diagnostic
imaging services in a comfortable, service-oriented environment located mainly
in an outpatient setting to patients referred by physicians. Of the Company's 94
centers, 82 provide magnetic resonance imaging, which accounts for a majority of
the Company's diagnostic imaging revenues. Many of the Company's centers also
provide some or all of the following services: Computerized Tomography,
Ultrasound, Nuclear Medicine, General Radiology and Fluoroscopy and Mammography.
 
    INTERPRETING PHYSICIAN ARRANGEMENTS.  At each of the Company's centers, all
medical services are performed exclusively by physician groups (the "Physician
Group" or the "Interpreting Physician"), generally consisting of radiologists,
with whom the Company enters into independent contractor agreements. Pursuant to
these agreements, the Company, among other duties, provides to the Physician
Group the diagnostic imaging facility and equipment, performs all marketing and
administrative functions at the centers and is responsible for the maintenance
and servicing of the equipment and leasehold improvements. The Physician Group
is solely responsible for, and has complete and exclusive control over, all
medical and professional services performed at the centers, including, most
importantly, the interpretation of diagnostic images, as well as the supervision
of technicians, and medical-related quality assurance and communications with
referring physicians.
 
    Insofar as the Physician Group has complete and exclusive control over the
medical services performed at the centers, including the manner in which medical
services are performed, the assignment of individual physicians to center duties
and the hours that physicians are to be present at the center, the Company
believes that the Interpreting Physicians who perform medical services at the
centers are independent contractors. In addition, Physician Groups that furnish
professional services at the centers generally have their own medical practices
and, in most instances, perform medical services at non-Company related
facilities. The Company's employees do not perform professional medical services
at the centers. Consequently, the Company believes that it does not engage in
the practice of medicine in jurisdictions that prohibit or limit the corporate
practice of medicine. The Company performs only administrative and technical
services and does not exercise any control over the practice of medicine by
physicians at the centers or employ physicians to provide medical services. The
Company is aware of three Interpreting Physicians who own a nominal percentage
of three limited partnerships that are managed and partially owned by the
Company.
 
    As part of its administrative responsibilities under the terms of the
Interpreting Physician agreements, the Company is responsible for the
administrative aspects of billing and collection functions at the centers.
Certain third-party payor sources, such as Medicare, insurance companies and
managed care organizations, require that they receive a single or "global"
billing statement for the imaging services provided at the Company's centers.
Consequently, billing is done in the name of the Physician Group because such
billings include a medical component. The Physician Group grants a power of
attorney to the Company authorizing the Company to establish bank accounts using
the Physician Group's name related to that center's collection activities and to
access such accounts. In states where permitted by law, such as Florida, the
Company generally renders bills in the center's name. In such circumstances, the
Physician Group has no access to associated collections.
 
    The Company recognizes revenue under its agreements with Interpreting
Physicians in one of three ways: (I) the Company receives a technical fee for
each diagnostic imaging procedure performed at the center, the amount of which
is fixed based upon the type of the procedure performed; (II) the Company pays
the Interpreting Physicians a fixed percentage of fees collected at the center,
or a contractually fixed amount based upon the specific diagnostic imaging
procedures performed; or, (III) the Company receives
 
                                       40
<PAGE>
from an affiliated physician association a fee for the use of the premises, a
fee per procedure for acting as billing and collection agent for the affiliated
physician association and for administrative and technical services performed at
the centers and the affiliated physician association pays the Physician Group
based upon a percentage of the cash collected at the center. All of such amounts
and the basis for payments are negotiated between the Physician Group and the
Company.
 
    The fees received or retained by the Company under the three types of
agreements with Interpreting Physicians described above, expressed as a
percentage of the gross billings net of contractual allowances for the imaging
services provided, range from 78% to 93% for the agreements described in item
(I), 80% to 93% for the agreements described in item (II) and 80% to 89% for the
agreements described in item (III). The agreements generally have terms ranging
from one to ten years. For additional information pertaining to the Company's
arrangements with Interpreting Physicians, see Note 1 to the Company's
Consolidated Financial Statements--Revenue Recognition.
 
    SALES AND MARKETING.  The Company develops and coordinates marketing
programs which center managers, sales representatives, affiliated Interpreting
Physicians and corporate managers utilize in an effort to establish and maintain
profitable referring physician relationships and to maximize reimbursement
yields. These marketing programs identify and target selected market segments
consisting of area physicians with certain desirable medical specialties and
reimbursement yields. Corporate and center managers determine these market
segments based upon an analysis of competition, imaging demand, medical
specialty and/or payor mix of each referral from the local market. The Company
also directs marketing efforts at managed care organizations.
 
    Managed care organizations are becoming an increasingly important factor in
the diagnostic imaging industry, and, consequently, the Company places major
emphasis on cultivating and developing relationships with such organizations.
The Company employs industry professionals who have significant experience in
dealing with managed care and other providers. The Company believes that the
geographic concentration of its centers, the presence of multi-modality centers
in all of its regions, its ability to offer cost effective services and its
experience in developing relationships with various managed care organizations
will constitute a competitive advantage with managed care organizations.
 
    PERSONAL INJURY REVENUE.  A significant percentage of the Company's net
service revenues from imaging centers is derived by providing imaging services
to individuals involved in personal injury claims, mainly involving automobile
accidents. Imaging revenue derived from personal injury claims, mainly involving
automobile accidents, represented approximately 24% of the Diagnostic Imaging
business net service revenues for 1997. Due to the greater complexity in
processing receivables relating to personal injury claims with automobile
insurance carriers (including dependency on the outcome of settlements or
judgements for collections directly from such individuals), such receivables
typically require a longer period of time to collect, compared to the Company's
other receivables and, in the experience of the Company, incur a higher bad debt
expense.
 
    While the collection process employed by the Company varies from
jurisdiction to jurisdiction, the processing of a typical personal injury claim
generally commences with the Company obtaining and verifying automobile, primary
health and secondary health insurance information at the time services are
rendered. The Company then generates and sends a bill to the automobile
insurance carrier, which under state law, typically has an extended period of
time (usually up to 105 days) to accept or reject a claim. The amount of
documentation required by the automobile insurance carriers to support a claim
is substantially in excess of what most other payors require and carriers
frequently request additional information after the initial submission of a
claim. If the individual is subject to a co-payment or deductible under the
automobile insurance policy or has no automobile insurance coverage, the Company
generally will bill the individual's primary and secondary health policies for
the uncovered balance. The automobile insurance carrier may reject coverage or
fail to accept a claim within the statutory time limit on the basis of, among
 
                                       41
<PAGE>
other reasons, the failure to provide complete documentation. In such
circumstances, the Company may pursue arbitration, which typically takes up to
90 days for a judgment, to collect from the carrier.
 
    The Company will then pursue collection of the remaining receivable from the
individual. Although the Company attempts to bill promptly after providing
services and typically requests payment upon receipt of invoice, the Company
generally defers aggressive collection efforts for the remaining balance until
the individual's claim is resolved in court, which frequently takes longer than
a year and may take as long as two or three years. Consequently, the Company's
practice is to attempt to obtain a written assurance from the individual and the
individual's legal counsel, under which the individual confirms in writing his
or her obligation to pay the outstanding balance regardless of the outcome of
any settlement or judgment of the claim. If the settlement or judgment proceeds
received by the individual are insufficient to cover the individual's obligation
to the Company, and the individual does not otherwise satisfy his or her
liability to the Company, the Company either (i) accepts a reduced amount in
full satisfaction of the individual's outstanding obligation, or (ii) commences
collection proceedings, which may ultimately result in the Company taking legal
action to enforce its collection rights against the individual regarding all
uncollected accounts. As a result of the foregoing, the average age of
receivables relating to personal injury claims is greater than for non-personal
injury claim receivables.
 
    MANAGED CARE CAPITATION AGREEMENTS.  The Company has entered into a number
of "capitated contracts" with third party payors which typically provide for the
payment of a fixed fee per month on a per member basis, without regard to the
amount or scope of services rendered. Because the obligations to perform service
are not related to the payments, it is possible that either the cost or the
value of the services performed may significantly exceed the fees received, and
there may be a significant period between the time the services are rendered and
payment is received. While only approximately 2% of the Company's 1997 net
service revenues were derived from capitated contracts, and although prior to
entering into any such contracts the Company carefully analyzes the potential
risks of capitation arrangements, there can be no assurances that any capitated
contracts to which the Company is or may in the future become a party will not
generate significant losses to the Company.
 
    In addition, certain types of capitation agreements may be deemed a form of
risk contracting. Many states limit the extent to which any person can engage in
risk contracting, which involves the assumption of a financial risk with respect
to providing services to a patient. If the fees received by the Company are less
than the cost of providing the services, the Company may be deemed to be acting
as a de facto insurer. In some states, only certain entities, such as insurance
companies, HMOs and independent practice associations, are permitted to contract
for the financial risk of patient care. In such states, risk contracting in
certain cases has been deemed to be engaging in the business of insurance. The
Company believes that it is not in violation of any restrictions on risk bearing
or engaging in the business of insurance. If the Company is held to be
unlawfully engaged in the business of insurance, such finding could result in
civil or criminal penalties or require the restructuring of some or all of the
Company's operations, which could have a material adverse effect upon the
Company's business.
 
    BILLINGS AND COLLECTIONS.  Under the Interpreting Physician agreements, the
Company is generally responsible for preparing and submitting bills per imaging
study performed. The preparation and submission of bills is completed by each
center, or by a regional billing office, generally on behalf of and in the name
of the appropriate Interpreting Physician. Prior to 1998, each center was also
responsible for collecting its own receivables and pursuing any parties that
were delinquent in payment of their bills. In February 1998, the Company
commenced a restructuring of its collection efforts for the purpose of
ultimately consolidating all collection activities within four or more regional
collection offices. The restructuring is in response to the need to improve
overall collection results and controls, and to better coordinate collection
efforts previously employed by individual centers (especially where third
parties had been retained to manage the center's collection efforts), as well as
the need to integrate the Company's 1997 acquisitions and to insure consistent
Company-wide collection policies and practices.
 
                                       42
<PAGE>
    MANAGEMENT INFORMATION SYSTEMS.  The Company acquired Dalcon in September
1997. As of June 1998, a substantial majority of the Company's imaging centers
had been fully operating on Dalcon's ICIS radiology information system. The ICIS
radiology information system is designed to, among other things, enhance the
efficiency and productivity of the Company's centers, lower operating costs,
facilitate financial controls, increase reimbursement and assist in the analysis
of sales, marketing and referral data. The ICIS system provides on-line,
real-time information, reporting and access to managers with respect to billing,
patient scheduling, marketing, sales, accounts receivable, referrals and
collections, as well as other matters.
 
    HEALTHCARE REFORM AND COST REDUCTION EFFORTS.  Third-party payors, including
Medicare, Medicaid, managed care/HMO organizations and certain commercial payors
have taken extensive steps to contain or reduce the costs of healthcare. In
certain areas, the payors are subject to regulations which limit the amount of
payments. Discussions within the Federal government regarding national
healthcare reform are emphasizing containment of healthcare costs. In addition,
certain managed care organizations have negotiated capitated payment
arrangements for imaging services. Under capitation arrangements, diagnostic
imaging service providers are compensated using a fixed rate per member of the
managed care organization regardless of the number of procedures performed or
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 Company's business. The inability of the Company to
properly manage the administration of capitated contracts could materially
adversely effect the Company. Although patients are ultimately responsible for
payment of services rendered, substantially all of the Company's 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 Company's respective imaging
centers' revenues, profitability and cash flow.
 
    The Company's management believes that overall reimbursement rates will
continue to gradually decline for some period of time due to factors such as the
expansion of managed care organizations and continued national healthcare reform
efforts. The Company enters into contractual arrangements with managed care
organizations which, due to the size of their membership, are able to command
reduced rates for services. The Company expects these agreements to increase the
number of procedures performed due to the additional referrals from these
managed care entities. However, there can be no assurance that the increased
volume of procedures associated with these contractual arrangements will offset
the reduction in reimbursement rate per procedure.
 
ACQUIRED CENTERS; COMMON STOCK REPURCHASE OBLIGATIONS
 
    Since 1996, the Company has grown by aggressively acquiring imaging centers
and integrating their operations. The Company has acquired 92 imaging centers
through 27 acquisitions since January 1, 1996. When the Company acquires an
imaging center, it generally acquires assets relating to the provision of
technical, financial, administrative and marketing services which support the
provision of medical services performed by the Interpreting Physicians. Such
assets typically include equipment, furnishings, supplies, tradenames of the
center, books and records, contractual rights with respect to leases, managed
care and other agreements and, in most instances, accounts receivable. Other
than with respect to such accounts receivable for services performed by the
acquired company, the Company does not acquire any rights with respect to or
have any direct relationship, with patients. Patients have relationships with
referral sources who are the primary or specialty care physicians for such
patients. These physicians refer their patients to diagnostic imaging centers
which may include the Company's centers where Interpreting Physicians, under
independent contractor agreements, provide professional medical services. The
Company's acquired imaging centers do not constitute either a radiology, primary
care or specialty care medical practice. In connection with an acquisition of a
center, the Company will generally enter into an agreement, as
 
                                       43
<PAGE>
described above, with a Physician Group to act as an independent contractor to
perform medical services at the center.
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as consideration, the Company agreed
to register such shares for resale pursuant to the federal securities laws. In
certain of such acquisitions, the Company has granted specific remedies to the
sellers in the event that a registration statement covering the relevant shares
is not declared effective by the Securities and Exchange Commission (the "SEC")
within an agreed-upon period of time, including the right to require the Company
to repurchase the shares issued to such seller. In the event the Company is
unable to register such shares by the required dates, the Company would become
obligated to repurchase the shares issued in connection with such acquisition.
As of September 1, 1998, the Company had not registered any shares of Common
Stock issued in connection with the Company's 1997 acquisitions under a
registration statement declared effective by the SEC. As of December 31, 1997
and June 30, 1998, the Company had reflected $9,734,000 and $5,509,000,
respectively, of Common Stock subject to redemption on its Consolidated Balance
Sheets related to shares that the Company may be required to repurchase. During
the first six months of 1998, the Company paid $3,311,000 to sellers who
exercised their rights to have shares of Common Stock repurchased. In addition,
the Company expects to become obligated to pay an additional $5,509,000 during
the remainder of 1998 in connection with the settlement of certain repurchase
obligations of the Company subject to, under certain circumstances, the consent
of the Senior Note holders. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources."
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay to the seller (in
additional shares and/or cash) an amount equal to the shortfall in the value of
the issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement. Based
upon the closing sales price of the Company's Common Stock on September 1, 1998
($4.00 per share), such shortfall would be approximately $3,351,000, excluding
Price Protection obligations related to the shares which have repurchase
obligations referred to above.
 
    In connection with certain of the Company's acquisitions, the Company has
also agreed with certain sellers that all or a portion of the consideration for
such acquisitions will be paid on a contingent basis based upon the
profitability, revenues or other financial criteria of the acquired business
during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differs for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both.
 
    Although the Company has the option, in certain of such cases, to pay
certain of such amounts in shares of Common Stock, payment of significant cash
funds to sellers in the event such remedies or earnout provisions are triggered
could have a material adverse effect on the Company's cash flow and financial
condition. In addition, the Company may be required to finance all or a portion
of any such cash payments from third-party sources. No assurance can be given
that such capital will be available on terms acceptable to the Company. In
addition, the issuance by the Company of shares of Common Stock in payment of
any such owed amounts could be dilutive to the Company's stockholders.
 
COMPETITION
 
    The Company's business is highly competitive. In the Company's diagnostic
imaging business, competition focuses primarily on attracting physician
referrals at the local market level and, increasingly, referrals through
relationships with managed care and physician/hospital organizations. The
Company believes that
 
                                       44
<PAGE>
principal competitors in each of the Company's markets are hospitals,
independent or management company-owned imaging centers, individual-owned
imaging centers and mobile MR units. Many of these competitors have greater
financial and other resources than the Company. Principal competitive factors
include quality and timeliness of test results, ability to develop and maintain
relationships with managed care organizations and referring physicians, type and
quality of equipment, facility location, convenience of scheduling and
availability of patient appointment times. Competition for referrals can also be
affected by the ownership or affiliation of competing centers or hospitals.
 
GOVERNMENT REGULATION
 
    The healthcare industry is highly regulated at the Federal, state and local
levels. The following factors affect the Company's operation and development
activities:
 
    CERTIFICATES OF NEED, LICENSING AND CERTIFICATION
 
    Many of the states in which the Company currently operates or may operate
have laws that may require a certificate of need ("CON") in certain
circumstances to establish, construct, acquire or expand healthcare facilities
and services or for the purchase, expansion or replacement of major movable
equipment, including outpatient diagnosis imaging centers utilizing MR or other
major medical equipment. At the present time, the CON laws of New York,
Illinois, Florida, Maryland and California pertain to the Company's activities.
In states with CON programs, regulatory approvals are frequently required for
capital expenditures exceeding certain amounts, if such expenditures relate to
certain types of medical services or equipment.
 
    State CON statutes generally provide that prior to construction of new
facilities or the introduction of new services, a state health planning agency
(a "Planning Agency") must determine that a need exists for those facilities or
services. The CON process is intended to promote comprehensive healthcare
planning, assist in providing high quality health care at the lowest possible
cost and avoid unnecessary duplication by ensuring that only those healthcare
facilities that are needed will be built.
 
    Typically, the provider submits an application to the appropriate Planning
Agency with information concerning the geographic area and population to be
served, the anticipated demand for the facility or service to be provided, the
amount of capital expenditure, the estimated annual operating costs, the
relationship of the proposed facility or service to the overall state health
plan, if applicable, and the cost per patient for the type of care contemplated.
Whether the CON is granted is based upon a finding of need by the Planning
Agency in accordance with criteria set forth in CON statutes, applicable
regulations and applicable state and regional health facilities plans. If the
proposed facility or service is found to be necessary and the applicant to be an
appropriate provider, the Planning Agency will issue a CON containing a maximum
amount of expenditure and a specific time period for the holder of the CON to
implement the approved project.
 
    The necessity for these CON approvals serves as a barrier to entry in
certain markets which the Company wishes to service and has the potential to
increase the costs and delay the Company's acquisition, addition or expansion of
centers. A CON program or similar requirement has the potential to curtail the
Company's expansion which could have a material adverse effect on the Company's
future growth.
 
    The Company may also have to comply with Federal certification requirements.
For example, the Company's centers which provide mammography examinations must
be certified by the Federal government. Further, additional certification
requirements may affect the Company's centers, but such certification generally
will follow specific standards and requirements that are set forth in readily
available public documents. Compliance with the requirements often is monitored
by annual on site inspections by representatives of various government agencies.
The Company believes that it currently has obtained all necessary
certifications, but the failure to obtain a necessary certification could have a
material adverse effect on the Company's imaging business.
 
                                       45
<PAGE>
    In addition to the CON programs and Federal certification described above,
the operations of outpatient imaging centers are subject to Federal and state
regulations relating to licensure, standards of testing, accreditation of
certain personnel and compliance with government reimbursement programs. The
operation of these centers requires a number of Federal and state licenses,
including licenses for personnel and certain equipment. Although the Company
believes that currently it has obtained or is in the process of obtaining all
such necessary CON approvals and licenses, the failure to obtain a required
approval could have a material adverse effect on the Company's diagnostic
imaging business. The Company believes that diagnostic testing will continue to
be subject to intense regulation at the Federal and state levels and cannot
predict the scope and effect of such regulation nor the cost to the Company of
such compliance.
 
    MEDICARE ANTI-KICKBACK PROVISIONS
 
    The Federal Medicare and Medicaid Anti-Kickback Statute (the "Anti-Kickback
Statute") prohibits the offering, payment, solicitation or receipt of any form
of remuneration in return for the referral of patients covered by Medicare,
Medicaid or certain other Federal and state healthcare programs, or in return
for the purchase, lease or order or provision of any item or service that is
covered by Medicare or Medicaid or certain other Federal and state healthcare
programs. Violation of the Anti-Kickback Statute is punishable by substantial
fines, imprisonment for up to five years, or both. In addition, the Medicare and
Medicaid Patient and Program Protection Act of 1987 (the "Protection Act")
provides that persons guilty of violating the Anti-Kickback Statute may be
excluded from the Medicare or Medicaid programs. Investigations leading to
prosecutions and/or program exclusion may be conducted by the Office of
Inspector General ("OIG") of the Department of Health and Human Services
("HHS").
 
    The OIG has issued "safe harbor" regulations which describe practices that
will not be considered violations of the Anti-Kickback Statute. The fact that a
particular arrangement does not fall within a safe harbor does not mean that the
arrangement does not comply with the Anti-Kickback Statute. The safe harbor
regulations simply provide a guarantee that qualifying arrangements do not
violate this federal law. They do not extend the scope of the statutory
prohibitions. Thus, arrangements that do not qualify for safe harbor protection
are in largely the same position as they were prior to the promulgation of these
regulations, meaning that they must be carefully evaluated in light of the
provisions of the Anti-Kickback Statute itself. To the extent possible, the
Company will structure its agreements with referral sources, such as physicians
to comply with applicable safe harbors, but there are no assurances that it will
be able to so with every contract. Further, these safe harbor regulations have
so far been relatively untested in practice. No assurances can be given that a
Federal or state agency charged with enforcement of the Anti-Kickback Statute
and similar laws might not assert a contrary position or that new Federal or
state laws or new interpretation of existing laws might not adversely affect
relationships established by the Company with healthcare providers, including
physicians, or result in the imposition of penalties on the Company or certain
of its centers. The assertion of a violation, even if successfully defended by
the Company, could have a material adverse effect upon the Company.
 
    CORPORATE PRACTICE OF MEDICINE AND FEE SPLITTING
 
    The laws of many states prohibit unlicensed, non-physician-owned entities or
corporations from performing medical services or physicians from splitting fees
with non-physicians. The Company is unlicensed for certain of its services. The
Company does not believe however, that it engages in the unlawful practice of
medicine or the delivery of medical services in any state where it is
prohibited, and is not licensed to practice medicine in states which permit such
licensure. Professional medical services, such as the interpretation of MRI
scans, are separately provided by independent contractor Interpreting Physicians
pursuant to agreements with the Company. The Company performs only
administrative and technical services and does not exercise control over the
practice of medicine by physicians or employ physicians to provide medical
services. However, in many jurisdictions, the laws restricting the corporate
practice of medicine and fee-splitting have been subject to limited judicial and
regulatory interpretation
 
                                       46
<PAGE>
and, therefore, there can be no assurance that, upon review, some of the
Company's activities would not be found to be in violation of such laws. If such
a claim were successfully asserted against it, the Company could be subject to
civil and criminal penalties and could be required to restructure its
contractual relationships. In addition, certain provisions of its contracts with
Interpreting Physicians, including the payment of management fees and
restrictive covenants could be held to be unenforceable. Such results or the
inability of the Company to restructure its contractual relationships could have
a material adverse effect upon the Company.
 
    STARK LAW PROHIBITION ON PHYSICIAN REFERRALS
 
    The Federal "Stark Law" as amended in 1993 provides that when a physician
has a "financial relationship" with a provider of "designated health services"
(including, among other activities, the provision of MR and other radiology
services which are provided by the Company), the physician will be prohibited
from making a referral of Medicaid or Medicare patients to the healthcare
provider, and the provider will be prohibited from billing Medicare or Medicaid,
for the designated health service. In August 1995, regulations were issued
pursuant to the Stark Law as it existed prior to its amendment in 1993 (when it
only applied to clinical laboratories). Draft regulations for the provisions of
the Stark Law applicable to MR and other radiology services were issued in
January, 1998. Submission of a claim that a provider knows, or should know, is
for services for which payment is prohibited under the amended Stark Law, could
result in refunds of any amounts billed, civil money penalties of not more than
$15,000 for each service billed, and possible exclusion from the Medicare and
Medicaid programs.
 
    The Stark Law provides exceptions from its prohibition for referrals which
include certain types of employment, personal service arrangements and
contractual relationships. The Company continues to review all aspects of its
operations and endeavors to comply in all material respects with applicable
provisions of the Stark Law. Due to the broad and sometimes vague nature of this
law, the ambiguity of related regulations, the absence of final regulations, and
the lack of interpretive case law, there can be no assurance that an enforcement
action will not be brought against the Company or that the Company will not be
found to be in violation of the Stark Law.
 
    FALSE CLAIMS ACT
 
    A number of Federal laws impose civil and criminal liability for knowingly
presenting or causing to be presented a false or fraudulent claim, or knowingly
making a false statement to get a false claim paid or approved by the
government. Under one such law, the False Claims Act, civil damages may include
an amount that is three times the government's loss plus $5,000 to $10,000 per
claim. Actions to enforce the False Claims Act may be commenced by a private
citizen on behalf of the Federal government, and such private citizens receive
between 15 and 30 percent of the recovery. Efforts have been made to assert that
any claim resulting from a relationship in violation of the Anti-Kickback
Statute or the Stark Law is false and fraudulent under the False Claims Act. The
Company carefully monitors its submissions to HCFA and all other claims for
reimbursement to assure that they are not false or fraudulent.
 
    STATE LAWS
 
    Many states, including the states in which the Company operates, have
adopted statutes and regulations prohibiting payments for patient referrals and
other types of financial arrangements with healthcare providers, which, while
similar in certain respects to the Federal legislation, vary from state to
state. Some states expressly prohibit referrals by physicians to facilities in
which such physicians have a financial interest. Sanctions for violating these
state restrictions may include loss of licensure and civil and criminal
penalties assessed against either the referral source or the recipient provider.
Certain states also have begun requiring healthcare practitioners to disclose to
patients any financial relationship with other providers, including advising
patients of the availability of alternative providers.
 
                                       47
<PAGE>
    The Company continues to review all aspects of its operations and endeavors
to comply in all material respects with applicable provisions of the
Anti-Kickback Statute, the Stark Law and applicable state laws governing fraud
and abuse as well as licensing and certification. Due to the broad and sometimes
vague nature of these laws and requirements, the evolving interpretations of
these laws (as evidenced by the recent draft regulations for the Stark Law),
there can be no assurance that an enforcement action will not be brought against
the Company or that the Company will not be found to be in violation of one or
more of these regulatory provisions. Further, there can be no assurance that new
laws or regulations will not be enacted, or existing laws or regulations
interpreted or applied in the future in such a way as to have a material adverse
effect on the Company, or that Federal or state governments will not impose
additional restrictions upon all or a portion of the Company's activities, which
might adversely affect the Company's business.
 
DISCONTINUED OPERATIONS OF STARMED
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
Divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold the stock of StarMed
to RehabCare Group, Inc. for $33 million. Due to the StarMed Sale, the results
of operations of StarMed are herein reflected in the Company's Consolidated
Statements Of Operations as discontinued operations.
 
    StarMed commenced its Per Diem operations in March 1995 and, since that
time, it had opened 31 offices, acquired 4 staffing companies operating six
additional offices and consolidated the operations of two other offices.
StarMed's per diem staffing division provided registered nurses, licensed
practical nurses, nursing assistants, therapists and medical transcriptionists
on a daily basis to healthcare facilities through 35 offices located in 16
states as of March 31, 1998. StarMed's Travel Nursing Division operated from a
central office in Clearwater, Florida and provided registered nurses and
operating room technicians for periods ranging from 8 to 26 weeks.
 
EMPLOYEES
 
    As of December 31, 1997, the Company had approximately 1,277 full time
employees. This number does not include the healthcare personnel contracted by
StarMed for its Per Diem and Travel Nursing divisions as of such date. The
Company is not a party to any collective bargaining agreements and considers its
relationship with its employees to be good.
 
INSURANCE
 
    The nature of the services provided by the Company expose the Company to
risk that certain parties may attempt to recover from the Company for alleged
wrongful acts committed by others. As a result of this risk, the Company
maintains workmen's compensation insurance, comprehensive and general liability
coverage, fire, allied perils coverage and professional liability insurance in
amounts deemed adequate by management to cover all potential risk. There can be
no assurance that potential claims will not exceed the coverage amounts, that
the cost of coverage will not substantially increase or require the Company to
insure itself or that certain coverage will not be reduced or become
unavailable.
 
PROPERTIES
 
    The Company leases its 36,133 square foot principal and executive offices
pursuant to two leases with terms of five years and four years, respectively,
remaining. The building also houses the Company's Hackensack imaging center. The
Company's 94 imaging centers range in size from approximately 1,500 to 11,400
square feet. Each center consists of a waiting/reception area and one room per
modality, dressing rooms, billing/administration rooms and radiologist
interpreting rooms. The Company owns the real
 
                                       48
<PAGE>
property in which certain of its centers operate, and leases its remaining
centers under leases which expire from December 1997 through October 2002 and,
in certain instances, contain options to renew. The Company believes that if it
were unable to renew the lease on any of these facilities, other suitable
facilities would be available to meet the Company's needs.
 
LITIGATION
 
    As described below, the Company and certain of its officers and directors
have been named as defendants in several actions filed in state and federal
court arising out of the events also described under "Certain Relationships and
Related Transactions", involving, among other matters, allegations against the
Company with respect to related-party transactions and securities fraud.
 
    On November 5, 1997, ZPR Investments, Inc., ZP Investments, Inc., Wyoming
Valley Physicians Imaging Center, L.P., Camp Hill Physicians Imaging Center,
L.P., Wexford Radiology, P.C., Sanoy Medical Group, Ltd., Reading Open Imaging,
P.A., Yonas Zegeye, M.D., and Hirut Seleshi, parties who had agreed to sell to
the Company five related imaging centers located in Pennsylvania, brought action
in the Court of Chancery of the State of Delaware, New Castle County, against
the Company and five recently formed subsidiaries of the Company, seeking
specific performance of the acquisition agreements and unspecified breach of
contract damages. The plaintiffs alleged that the Company and the subsidiaries
failed to consummate the acquisition in accordance with the terms of the
acquisitions agreements. The aggregate purchase price for the acquisitions is
$8.4 million in cash and $5.6 million payable in shares of Company Common Stock
based upon the average price for the five business days preceding September 21,
1997 (approximately 106,666 shares). Pursuant to the acquisition agreement, the
shares of Common Stock issued in connection with such acquisition are subject to
price protection of the issuance price compared to the market price at
effectiveness of the registration statement. In December 1997, the Company
entered into an amended agreement to settle such action and therein agreed to
purchase the centers for $1 million in cash, a promissory note for $7.4 million,
plus interest, $5.6 million payable in shares of Company Common Stock, and the
payment of certain fees. The plaintiffs have announced that they do not intend
to go forward with the sale, although they continue to claim that the Company is
in breach of the acquisition agreements. The litigation in the Court of Chancery
remains stayed.
 
    On November 7, 1997, William D. Farrell resigned from his position as
President and Chief Operating Officer of the Company and as Director and Gary I.
Fields resigned from his position as Senior Vice President and General Counsel.
On the same date, Messrs. Farrell and Fields, filed a Complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and the
members of the Company's Board of Directors, claiming retaliatory discharge
under the New Jersey Conscientious Employee Protection Act and breach of
contract. On December 17, 1997, the plaintiffs amended their complaint to add a
claim for violation of public policy. The plaintiffs allege that they were
constructively terminated as a result of their objection to certain
related-party transactions, the purported failure of the defendants to
adequately disclose the circumstances surrounding such transactions, and the
Company's public issuance of allegedly false and misleading accounts concerning
or relating to such related-party transactions. The plaintiffs seek unspecified
compensatory and punitive damages, interest and costs and reinstatement of the
plaintiffs to their positions with the Company. On April 8, 1998, the Company
filed its Answer to the Amended Complaint, and asserted a counterclaim against
Messrs. Farrell and Fields for breach of fiduciary duties. The Company intends
to defend vigorously against the allegations.
 
    On November 12, 1997, Mr. Gerald Broder, who claims to be a company
stockholder, filed a derivative suit in the Court of Chancery of the State of
Delaware, New Castle County, naming the Company and Stephen M. Davis, Gary L.
Fuhrman, John H. Josephson, Neil H. Koffler, and Gary N. Siegler as defendants.
The complaint alleges that members of the Company's Board of Directors breached
their fiduciary duties owed to the Company and its stockholders by allegedly
engaging in self-dealing transactions that caused the Company financial harm.
The complaint seeks injunctive relief directing such directors to account to the
Company for its damages and their profits from the wrongs complained of
 
                                       49
<PAGE>
therein, enjoining them from continuing to engage in self-dealing transactions
harmful to the Company and its shareholders, and awarding plaintiff the costs
and expenses incurred in bringing the lawsuit. On April 1, 1998, the plaintiffs
amended their complaint to add additional factual allegations. The Company
intends to defend vigorously against the allegations.
 
    On November 14, 1997, Mr. John P. O'Malley III filed a complaint in the
Superior Court of New Jersey, Law Division, Essex County, against the Company
and Gary N. Siegler, Neil H. Koffler, Stephen M. Davis, Gary L. Fuhrman, John H.
Josephson and Lawrence Ramaekers, as defendants, claiming retaliatory discharge
under the New Jersey Conscientious Employee Protection Act and defamation. Mr.
O'Malley alleges that the Company terminated his employment in retaliation for
voicing the concerns of shareholders and senior management regarding
related-party transactions and because the Company did not want to make full and
adequate disclosure of the facts and circumstances surrounding such
transactions. In addition, the plaintiff alleges that the Company published
false and defamatory statements about him. Mr. O'Malley seeks unspecified
compensatory and punitive damages, interest and costs of bringing the action. On
April 8, 1998, the Company filed its Answer to the Complaint, and asserted a
counterclaim against Mr. O'Malley for breach of fiduciary duties. The Company
intends to defend vigorously against the allegations.
 
    Between November 14, 1997 and January 9, 1998, seven class action lawsuits
were filed in the United States District Court for the District of New Jersey
against the Company and certain of the Company's directors and/or officers. On
November 14, 1997, Joan D. Ferrari, who claims to be a Company stockholder,
filed a lawsuit on behalf of all persons who purchased Common Stock during the
period between May 15, 1997 and November 7, 1997. The Ferrari complaint names as
defendants the Company and Gary N. Siegler, Stephen M. Davis, Gary L. Fuhrman,
John H. Josephson and Neil H. Koffler. On November 18, 1997, Tri-Masonry
Company, who claims to be a Company stockholder, filed a complaint on behalf of
all persons who purchased Common Stock during the period between March 19, 1997
and November 10, 1997. On November 19, 1997, Yaakov Prager, who claims to be a
Company stockholder, filed a complaint on behalf of all persons who purchased
Common Stock during the period between May 16, 1997 and November 10, 1997. The
Tri-Masonry and Prager complaints name as defendants the Company, William D.
Farrell, John P. O'Malley and Gary N. Siegler. On November 20, 1997, Albert
Schonert, who claims to be a Company stockholder, filed a complaint on behalf of
all persons who purchased Common Stock during the period between May 15, 1997
and November 7, 1997. The Schonert complaint names as defendants the Company and
Gary N. Siegler, Stephen M. Davis, Gary L. Fuhrman, John H. Josephson, Neil H.
Koffler and William D. Farrell. On December 12, 1997, Anne Benjamin, Scott L.
Benjamin, Maxine Benjamin, Donald Benjamin and Andrew M. Schreiber, who claim to
be Company stockholders, filed a complaint on behalf of all persons who
purchased Common Stock during the period between March 31, 1997 and November 10,
1997. The Benjamin complaint names as defendants the Company and Gary N.
Siegler, John P. O'Malley and William D. Farrell. On December 31, 1997, Allen H.
Weingarten, who claims to be a Company stockholder, filed a complaint on behalf
of all persons who purchased Common Stock during the period between March 19,
1997 and November 10, 1997. The Weingarten complaint names as defendants the
Company and William D. Farrell, John P. O'Malley and Gary N. Siegler. On January
9, 1998, Roselle Sachs, who claims to be a Company stockholder, filed a
complaint on behalf of all persons who purchased Common Stock during the period
between May 15, 1997 and November 10, 1997. The Sachs complaint names as
defendants the Company and Gary N. Siegler, Stephen M. Davis, Gary L. Fuhrman,
Neil H. Koffler and William D. Farrell.
 
    The complaints in each action assert that the Company and the named
defendants violated Section 10(b), and that certain named defendants violated
Section 20(a) of the Securities Exchange Act of 1934 (the "Exchange Act"),
alleging that the Company omitted and/or misrepresented material information in
its public filings, including that the Company failed to disclose that it had
entered into acquisitions that were not in the best interest of the Company,
that it had paid unreasonable and unearned acquisition and financial advisory
fees to related parties, and that it concealed or failed to disclose adverse
material
 
                                       50
<PAGE>
information about the Company. The complaints each seek unspecified compensatory
damages, with interest, and the costs and expenses incurred in bringing the
action. On February 9, 1998, the Honorable Joel Pisano, United States Magistrate
Judge, entered an Order consolidating the above-mentioned class actions for all
purposes. On March 31, 1998, the lead plaintiffs in the consolidated class
actions served their Consolidated Class Action Complaint, asserting that the
Company and the named defendants violated Section 10(b) of the Exchange Act, and
that certain named defendants violated Sections 20(a) and 20A of the Exchange
Act. The Company intends to defend vigorously against the allegations.
 
    As previously disclosed by the Company, the U.S. Attorney for the District
of New Jersey commenced an investigation in connection with the disclosures
regarding the related-party transactions referenced above. In addition as
previously disclosed, the Company has received an inquiry from the SEC, but no
formal proceedings have been commenced by the SEC. The Company has cooperated
fully with these authorities and provided all information requested by them.
 
    In 1996, Lavina Orsi and Pompeo Orsi brought an action in the Supreme Court
of the State of New York, King's County against Advanced MRA Imaging Associates
in Brooklyn, New York, a wholly owned subsidiary of the Company ("MRA Imaging"),
for damages aggregating $12.5 million. The plaintiff alleges negligent
operations, improper supervision and hiring practices and the failure to operate
the premises in a safe manner, as a result of which the individual suffered
physical injury. The Company's general liability and professional negligence
insurance carriers have been notified, and it has been agreed that the general
liability insurance will pursue the defense of this matter, however such
insurers have reserved the right to claim that the scope of the matter falls
outside the Company's coverage. The parties to this matter are engaged in
discovery.
 
    On June 2, 1998, Mr. Ronald Ash filed a complaint against the Company,
StarMed, Wesley Medical Resources, Inc., a subsidiary of the Company ("Wesley"),
and certain officers and directors of the Company in the United States District
Court for the Northern District of California. The complaint, among other
things, alleges that the defendants omitted and/or misrepresented material
information in the Company's public filings and that they concealed or failed to
disclose adverse material information about the Company in connection with the
sale of Wesley to the Company by the plaintiff. The plaintiff seeks damages in
the amount of $4.25 million or, alternatively, rescission of the sale of Wesley.
The Company believes that it has meritorious defenses to the claims asserted by
plaintiff, and intends to defend itself vigorously.
 
    The legal proceedings described above are in their preliminary stages.
Although the Company believes it has meritorious defenses to all claims against
it, the Company is unable to predict with any certainty the ultimate outcome of
those proceedings.
 
    In the normal course of business, the Company is subject to claims and
litigation other than those set forth above. Management believes that such other
litigation will not have a material adverse effect on the Company's financial
position, cash flows or results of operations.

plans during the salary continuation period unless such benefits are provided by
another employer. Mr. Montopoli is prohibited from competing with the Company

Agreement.
 
    The Company is a party to an employment agreement with Mr. William D.
Farrell dated January 1, 1997, which was scheduled to expire on December 31,
1999. Pursuant to such employment agreement, Mr. Farrell acted as President and
Chief Operating Officer of the Company, for which he received an annual salary
of $225,000. In addition, pursuant to such agreement, Mr. Farrell is prohibited
from competing with the Company for a period of one year following the
termination of the agreement. On November 7, 1997, Mr. Farrell resigned from his
position as President and Chief Operating Officer of the Company. The Company is
in litigation with Mr. Farrell relating, in part, to Mr. Farrell's employment
agreement. See "Litigation" and "Certain Relationships and Related
Transactions."
 
    The Company is party to a non-competition and consulting agreement with Mr.
John P. O'Malley III which expired on August 30, 1998 entered into in connection
with the acquisition of NMR in August 1996 (the "NMR Acquisition"). Pursuant to
such consulting agreement, Mr. O'Malley receives $550,000 annually, and the

amount of the bonus shall be determined by the Board of Directors at its
discretion and paid no later than March 15 of the calendar year following the
calendar year for which the
 
                                       55
<PAGE>
bonus is awarded. In connection with the execution of the Whynot Employment
Agreement, the Company granted to Mr. Whynot ten-year options to purchase 53,333
shares of Common Stock at an exercise price of $31.875. Such options were to
vest in four equal annual installments beginning March 23, 1999, unless sooner

employment is terminated by the Company other than for "Cause" or "Disability"
(as such terms are defined in the Whynot Employment Agreement), or if Mr. Whynot

Agreement), the Company shall (i) pay him a lump sum payment equal to his
accrued but unpaid salary and a portion of the bonus he would have received for

employer; FURTHER, PROVIDED that if such termination occurs within 12 months
following a "Change in Control" (as defined in the Whynot Employment Agreement),
Mr. Whynot shall receive a lump sum payment equal to 12 months of his then base
salary, which amount shall not be subject to reduction for any compensation
earned from another employer; and (iii) continue benefits under the Company's
employee welfare plans during the salary continuation period unless such
benefits are provided by another employer. Mr. Whynot is prohibited from
competing with the Company for a period of 12 months following the termination
of the Whynot Employment Agreement.
 
    The Company is a party to an employment agreement with Mr. Christopher J.
Joyce (the "Joyce Employment Agreement"). The term of the Joyce Employment
Agreement shall continue until terminated by either the Company or Mr. Joyce.
Pursuant to the Joyce Employment Agreement, Mr. Joyce acts as Senior Vice
President--Legal Affairs and Administration which position includes serving as
the Company's General Counsel and Secretary, and is entitled to receive an
annual base salary of $170,000. Such annual salary may be increased from time to
time in the discretion of the Board of Directors. Mr. Joyce is also eligible to
receive a bonus for each calendar year during this term of employment provided
he is employed on the last day of the calendar year. For calendar year 1998, Mr.
Joyce shall receive a bonus not less than 50% of Mr. Joyce's base salary for
such year. For all other calendar years, the target amount of the bonus shall be
equal to 50% of Mr. Joyce's base salary for such year and the actual amount of
the bonus shall be determined by the Board of Directors, in its discretion, and
paid no later than March 15 of the calendar year following the calendar year for
which the bonus is awarded. In connection with the execution of the Joyce
Employment Agreement, the Company granted to Mr. Joyce ten-year options to
purchase 40,000 shares of Common Stock at an exercise price of $31.875. Such
options were to vest in four equal annual installments beginning April 6, 1999,
unless sooner accelerated by certain "change of control" events. In the event
Mr. Joyce's employment is terminated by the Company other than for "Cause" or
"Disability" (as such terms are defined in the Joyce Employment Agreement), or
if Mr. Joyce terminates his employment for "Good Reason" (as defined in the
Joyce Employment Agreement), the Company shall (i) pay him a lump sum payment
equal to his accrued but unpaid salary and a portion of the bonus he would have
received for such year; (ii) continue his base salary for a period of 9 months;
and (iii) continue benefits under the Company's employee welfare plans during
the salary continuation period unless such benefits are provided by another
employer. Mr. Joyce is prohibited from competing with the Company for a period
of nine months following the termination of the Joyce Employment Agreement.
 
    Following the Company's 1998 Annual Meeting of Stockholders on July 23, 1998
at which the stockholders approved the Company's 1998 Stock Option Plan (the
"1998 Plan"), the Compensation Committee of the Board cancelled all of the
options granted to Messrs. Montopoli, Whynot and Joyce in connection with their
employment agreements described above. In exchange for such cancellation, on
July 23, 1998, the Compensation Committee granted Messrs. Montopoli, Whynot and
Joyce options to purchase 150,000, 41,666 and 31,333 shares of Common Stock,
respectively (the "New Options"), under the 1998 Plan. The exercise price of
$8.625 for all of the New Options granted to Messrs. Whynot and Joyce and
100,000 of the new Options granted to Mr. Montopoli equalled the fair market
value of the Common Stock on the date of grant. The remaining 50,000 New Options
granted to Mr. Montopoli were granted at an exercise price of $20.25, which
represented $11.625 over the fair market value of the Common Stock on the date
of grant. The Compensation Committee believes that such cancellation and
 
                                       56
<PAGE>
exchange was warranted in order to continue to provide an appropriate incentive
for Messrs. Montopoli, Whynot and Joyce to promote the success of the Company's
business, and because each of these executives joined the Company only recently
and after the end of the last fiscal year.

    In February 1996, the Company adopted and approved the 1996 Stock Option

<PAGE>
established or shall establish in connection with each participant in the 1996
Plan, which terms shall be reflected in an option agreement executed in
connection with the granting of the option. In fiscal 1997, no options were
granted under the 1996 Plan.
 
    1996 STOCK OPTION PLAN B
 
    In February 1996, the Company adopted and approved the 1996 Stock Option
Plan B (the "1996 B Plan"). The 1996 B Plan is designed to serve as an incentive
for retaining qualified and competent directors, employees and consultants. The

retaining qualified and competent directors, employees and consultants. As of
April 1, 1998, there were 580,333 shares of Common Stock subject to outstanding
options granted under the 1997 Plan. Due to the fact that the 1997 Plan was not
presented to the Company's shareholders for approval within one year of the

have lapsed and such grants are not deemed to be outstanding.

has, subject to the provisions of the 1998 Plan, full authority to select
eligible employees, consultants and directors of the Company and its
subsidiaries that may participate in the 1998 Plan and the type, extent and
terms of the options granted to them. The 1998 Plan provides for the awarding of
incentive stock options (as defined in Section 422 of the Internal Revenue Code
of 1986) and non-incentive stock options. Options granted pursuant to the 1998
Plan will have such vesting schedules and expiration dates as the Compensation
Committee shall establish in connection with each participant in the 1998 Plan,
which terms shall be reflected in an option agreement executed in connection
with the granting of the option.
 
1998 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN
 
    In July 1998, the Company's Board of Directors adopted and approved the 1998
Non-Employee Director Stock Option Plan (the "Directors Plan"). The Directors
Plan is designed to serve as an incentive for retaining qualified persons who
are neither employees nor officers of the Company to service as members of the
Board of Directors. The Directors Plan provides for the award of options to
purchase up to 66,666 shares of Common Stock, of which 20,000 shares were
subject to outstanding options as of September 1, 1998. The Directors Plan can
be administered by either the Board of Directors or the
 
                                       58
<PAGE>
Compensation Committee. Unless otherwise determined by the Compensation
Committee, the Directors Plan provides for automatic grants of options to
purchase up to 3,333 shares of Common Stock at the time a person becomes a
non-employee director and on an annual basis thereafter. The options granted
pursuant to the Directors Plan are not intended to be incentive stock options
(as defined in Section 422 of the Internal Revenue Code of 1986). Options
granted pursuant to the Directors Plan will have exercise prices equal to the
fair market value of the Common Stock on the date of grant, will expire ten
years from the date of grant and generally vest in equal quarterly installments
over a one-year period.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    During 1997, in connection with the placement of the Series C Convertible
Preferred Stock, the Company paid $967,000 in fees and expenses to the placement
agent, Arnhold and S. Bleichroeder, Inc. ("ASB"), of which Gary Fuhrman, a
director of the Company, is an executive officer and director. In addition, ASB
acted as placement agent for the private placement of certain of the Company's
debentures in 1996 and 1995 for which it was paid placement agent fees and
expenses in 1996 and 1995 of $356,650 and $247,500, respectively. Also during
1997, for legal services rendered to the Company, the Company paid legal fees
and expenses in the amount of $971,000 to Werbel & Carnelutti, of which Stephen
Davis, a former director of the Company, is a partner. Mr. Davis' firm also
performed legal services for the Company during 1996 and 1995. In addition,
during 1997, the Company reimbursed the managing underwriter of the Company's
October 1996 public offering $84,000 in charter fees (which rates were at or
below market rates) for the use by the managing underwriter and the Company of
an airplane owned by an affiliate of Mr. Gary N. Siegler, a director of the
Company and former Chairman of the Board of the Company, during the public
offering roadshow.
 
    In 1997 and previous years, the Company paid an annual financial advisory
fee to 712 Advisory Services, Inc., a financial advisory firm of which Mr. Gary
N. Siegler is the sole stockholder, sole director and president (the
"Affiliate"). Mr. Neil H. Koffler, a director of the Company, is also an
employee of the Affiliate. Such fees amounted to $112,500, $102,000 and $225,000
in the years ended December 31, 1997, 1996, and 1995, respectively. During the
year ended December 31, 1997, the Company also paid transaction related advisory
fees and expenses (including fees associated with the issuance of the Senior
Notes) to the Affiliate of $1,761,000 and issued to the Affiliate warrants to
purchase 225,000 shares of the Company's Common stock exercisable at prices
ranging from $30.93 to $37.77 per share for financial advisory services rendered
to the Company in connection with such transactions. As discussed below,
pursuant to recommendations made by a special committee of the Board of
Directors, the Affiliate has reimbursed to the Company $1,536,000 of the fees
paid to the Affiliate for services rendered in 1997 and waived $112,500 of fees
payable for 1997. In addition, during 1996, the Company paid transaction related
advisory fees and expenses to the Affiliate of $363,000 and issued to the
Affiliate warrants to purchase 40,000 shares of Common Stock at $27.00 per share
for services rendered to the Company in connection with the Company's
acquisition of NMR, a public offering by the Company of its Common Stock and
other transactions.
 
    In order to compensate officers, directors, employees and consultants to the
Company for services rendered or to be rendered to the Company, the Company from
time to time has granted options at fair market value to such individuals. As of
December 31, 1997, stock options to purchase 489,555 shares of the Company's
Common Stock had been issued to Mr. Siegler and Mr. Koffler. Included in this
amount were stock options to purchase 250,000 shares and 5,000 shares of the
Company's Common Stock which were granted to Mr. Siegler and Mr. Koffler,
respectively, under the 1997 Plan. As discussed below, Mr. Siegler and Mr.
Koffler voluntarily agreed to relinquish the stock options that were granted to
them under the 1997 Plan and to permit the Board's Compensation Committee, with
the assistance of compensation experts, to determine the appropriate director
compensation for them for 1997.
 
    Additionally, in September 1997, the Company acquired, for $3.25 million, a
limited partnership interest in Dune Jet Services, L.P. (the "Partnership"), a
Delaware limited partnership formed for the purposes of acquiring and operating
an airplane for the partners' business uses and for third-party charter flights.
The general partner of the Partnership is Dune Jet Services, Inc., a Delaware
corporation, the sole stockholder of which is Mr. Siegler. In October 1997, the
Company's interest in the Partnership was repurchased by the Partnership at cost
plus interest following discussions among management (members of which expressed
objections to such acquisition), a special committee of the Company's Board of
Directors (the "Committee"), and other members of the Board of Directors
(including Mr. Siegler).

    In February 1995, the Company consummated the acquisition (the "Maternity
Acquisition") of Maternity Resources, Inc. ("Maternity"), a manufacturer and
retailer of maternity apparel. The Maternity Acquisition was consummated
pursuant to a stock purchase agreement (the "Maternity Agreement") among the
Company, Maternity and the securityholders of Maternity (the "Maternity
Sellers"). Pursuant to the Maternity Agreement, the Company acquired 100% of the
issued and outstanding common stock and preferred stock of Maternity from the
Maternity Sellers in exchange for an aggregate of 160,000 shares of Common Stock
and preferred stock of the Company. Messrs. Gary N. Siegler, a director of the
Company, and Peter M. Collery, a former director of the Company, were directors
and executive officers of, and securityholders in, the Maternity Sellers.
 
INDEPENDENT COMMITTEE INVESTIGATION INTO RELATED-PARTY TRANSACTIONS
 
    In October 1997, members of the Company's management communicated to the
Board that certain Company stockholders had questioned them regarding the manner
in which related-party transactions were being scrutinized by the Company and
its Board. Management stated that it shared the concerns of these stockholders
and had engaged counsel to conduct a review of such transactions.
 
    In order to address and satisfy the concerns management had communicated,
the Company authorized a review of its practices regarding related-party
transactions, as well as the fairness of all such transactions and the adequacy
of the disclosure of the same, including but not limited to transactions as to
which fees already had been paid and warrants and options to purchase shares had
been issued, and public disclosure had been made in prior periods. The review
also was to seek to develop recommendations as to what changes, if any, should
be made to the Company's procedures regarding related-party transactions.
 
    To oversee the review, the Board formed the Committee consisting of
directors who were not officers, directors, employees, stockholders or otherwise
affiliates of the Affiliate. The Committee retained, on behalf of the Company,
outside counsel with which neither the Company nor any of its directors has or
had any current or prior relationship, to assist and advise the Committee in the
conduct of the review. Mr. Siegler, on behalf of the Affiliate, expressed its
position that the related-party transactions and fees are and were proper, but
nevertheless advised the Committee that the Affiliate would return to the
Company any sums that the Committee deemed improper.
 
    Thereafter, in response to expressions of dissatisfaction with the Committee
and its ongoing review, as well as disclosure related thereto, by certain
members of management who questioned, among other things, the Committee's
ability to conduct an independent review, the Board determined, and the Company
announced, that it was seeking to add to the Board two new independent
directors. The new directors, who would retain other independent counsel of
their choice, would assume ultimate responsibility for the review. Mr. Siegler
and the Affiliate thereafter restated that although they believe that all
related-party transactions and financial advisory fees are and were proper, they
nevertheless agreed to abide by the findings of the Company's independent review
and to return to the Company any sums that the Committee deemed improper. On
December 8, 1997, D. Gordon Strickland and Peter J. Powers were appointed to the
Board of Directors of the Company and to serve as the members of the Committee
that was formed to examine the related-party transactions. The Committee engaged
the law firm of Kaye, Scholer, Fierman, Hays & Handler to advise and assist its
examination.
 
    The Committee issued the results of its investigation and certain
recommendations in a report to the Company's Board of Directors and on April 6,
1998, the Company's Board of Directors voted to adopt the recommendations
contained in the report.
 
    The Committee reported to the directors that it had determined that: (i)
there was no evidence of any federal or state crimes or securities law
violations in connection with the related party transactions in question; (ii)
all related-party matters were disclosed in public filings; (iii) the Affiliate
performed acquisition advisory services fully consistent with the expectations
and understanding of the committee of outside directors that had approved the
Affiliate's acquisition fees; and (iv) the acquisition advisory fees

<PAGE>
paid to the Affiliate in connection with the Company's acquisitions in 1997 were
within the range of customary acquisition advisory fees paid to investment
bankers on transactions of similar size.
 
    The Committee also recommended and the Board of Directors has adopted the
following measures to improve corporate governance:
 
    - To avoid any appearance of possible conflicts of interest, the Board
      adopted a policy disfavoring related-party transactions. The policy can be
      subject to exceptional circumstances, but even exceptional circumstances
      will be considered only in the informed judgment of the Board or an
      independent committee, assisted by independent counsel.
 
    - The Chief Executive Officer of the Company, with the assistance of the
      Company's general counsel and in consultation with the Board of Directors,
      will be responsible for the selection of all outside counsel, bearing in
      mind the policy disfavoring related-party transactions. To avoid any
      appearance of possible conflicts of interest, corporate counsel advising
      on issues of corporate governance and disclosure will have no relationship
      to any member of the Board of Directors. Without limiting the generality
      of the foregoing, no director of the Company will be a member of or
      counsel to such law firm. Corporate counsel advising on such issues will
      not otherwise provide legal services to any member of the Board of
      Directors, including entities affiliated with Board members.
 
    - Absent exceptional circumstances, all related-party contracts, unless
      manifestly immaterial, will be filed publicly with appropriate SEC
      filings.
 
    - The Compensation Committee has been authorized and directed to formulate
      clear written standards for reimbursement of director expenses, subject to
      review by the Board of Directors.
 
    In addition to the foregoing, the Committee recommended and the Board of
Directors has determined to endeavor to reconfigure the Board to give outside
directors a majority of its seats and select a new chairman from the outside
directors.
 
    The Committee understood that in late 1996, the Board of Directors had
turned to the Affiliate to supervise an extensive acquisition program of 59
diagnostic imaging centers and one staffing company because of the Board's
perceptions that former senior management was still relatively inexperienced and
did not yet have the formal training and necessary skills to manage an extensive
acquisition program, former senior management was not directly supervising nor
providing sufficient input with respect to the acquisition program, and there
was a limited window of time within which the acquisition program could take
place, given the increasingly competitive marketplace. The Committee expressed
their view that given the Board's perceptions, the Board should have acted
sooner to bring any additional needed skills in-house, rather than continue to
rely upon, and pay fees to, the Affiliate to provide such services.
 
    Accordingly, the Committee recommended and the Affiliate agreed to reimburse
the Company approximately $1,424,000 in fees for acquisition transactions
completed after June 1, 1997, to reimburse $112,500 of the retainer paid to the
Affiliate for 1997, to waive payment of an additional $112,500 of fees accrued
by the Company for the third and fourth quarters of 1997, and to pay a
substantial amount of the expenses associated with the Committee's
investigation. All such amounts have been reimbursed or paid to the Company. In
addition, in light of the subsequent hiring of Duane C. Montopoli as President
and Chief Executive Officer, Geoffrey Whynot as Chief Financial Officer and SBC
Warburg Dillon Read as Financial Advisor, the Committee recommended and the
Affiliate agreed to allow the Company to terminate its relationship with the
Affiliate.
 
    Mr. Siegler and Mr. Koffler also agreed voluntarily to relinquish 255,000
stock options that were granted to them in May 1997 and permit the Board's
Compensation Committee, with the assistance of compensation experts, to
determine the appropriate director compensation for them for 1997.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 50,000,000 shares of
Common Stock, par value $.01 per share, and 100,000 shares of Preferred Stock,
par value $.01 per share ("Preferred Stock"). As of September 8, 1998, the
Company had outstanding 7,929,950 shares of Common Stock.
 
COMMON STOCK
 
    The holders of outstanding shares of 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 Common Stock held by such
stockholder. The Company's Certificate of Incorporation does not provide for
cumulative voting. The Common Stock is not entitled to preemptive rights and is
not subject to redemption. Upon liquidation, dissolution, or winding-up of the
Company, the assets legally available for distribution to stockholders are
distributed ratably among the holders of Common Stock outstanding at that time
after payment of liquidation preferences, if any, on any outstanding Preferred
Stock. Each outstanding share of Common Stock is fully paid and nonassessable.
 
    PREFERRED STOCK PURCHASE RIGHTS.  Pursuant to the Company's Stockholder
Rights Plan, holders of the Common Stock possess three rights (the "Rights") to
purchase one ten thousandth of a share of Series C Junior Participating
Preferred Stock for each share of Common Stock owned. The Rights will generally
become exercisable ten days after a person or group acquires 15% of the
Company's outstanding voting securities or ten business days after a person or
group commences or announces an intention to commence a tender or exchange offer
that could result in the acquisition of 15% of any such securities. Ten days
after a person acquires 15% or more of the Company's outstanding voting
securities (unless this time period is extended by the board of directors) each
Right would, subject to certain adjustments and alternatives, entitle the
rightholder to purchase Common Stock of the Company or stock of the acquiring
company having a market value of twice the $24.00 exercise price of the Right
(except that the acquiring person or group and other related holders would not
be able to purchase common stock of the company on these terms). The Rights are
nonvoting, expire in 2006 and may be redeemed by the Company at a price of $.001
per Right at any time prior to the tenth day after an individual or group
acquired 15% of the Company's voting stock, unless extended. The purpose of the
Rights is to encourage potential acquirors to negotiate with the Company's Board
of Directors prior to attempting a takeover and to give the Board leverage in
negotiating on behalf of the stockholder the terms of any proposed takeover.
 
PREFERRED STOCK
 
    The Company's Certificate of Incorporation provides that the Company may,
without further action by the Company'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 rate, 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 Common Stock. In addition, the issuance of
Preferred Stock could have the effect of delaying or preventing a change in
control of the Company.
 
    SERIES C PREFERRED STOCK.  On July 21, 1997, the Company completed a private
placement of $18,000,0000 of a newly designated Series C Convertible Preferred
Stock (the "Series C Preferred Stock") to one institutional investor, RGC
International Investors, LDC. The face amount of the Preferred Stock accrues at
a rate of 3% per annum from the closing date to the conversion date. The
Preferred Stock is convertible from time to time into the Company's Common Stock
at a price equal to the lesser of (i) an amount equal to 100% of the average of
the closing bid prices of the Company's Common Stock for the
 
                                       66
<PAGE>
five consecutive trading days ending on the fifth trading day preceding a notice
of conversion and (ii) $62.10. The Company has agreed to file a registration
statement under the Securities Act of 1933 covering the shares of Common Stock
issuable upon conversion of the Preferred Stock issued in the private placement.
Subject to certain limitations, the Company may require the conversion of all
the outstanding Preferred Stock beginning 180 days following the date such
registration statement is declared effective by the Securities and Exchange
Commission.
 
TRANSFER AGENT
 
    The Transfer Agent and registrar for the Common Stock is American Stock
Transfer and Trust Company, New York, New York.

(10) The number of shares set forth in the table represents an estimate of the
    number of shares of Common Stock to be offered by such Selling Stockholders.
    Such Selling Stockholders are parties to certain acquisition agreements with
    the Company, in which the Company has agreed to pay (in additional shares
    and/or cash) to the Selling Stockholders an amount equal to the shortfall in
    the market value of the shares issued to such Selling Stockholders at the
    closings of the relevant acquisitions in the event the market value of such
    shares at the relevant effective date of this Registration Statement is less
    than the market value of such shares as of the closing of the acquisition
    or, in other cases, as of the execution of the relevant acquisition
    agreement. The actual number of shares of Common Stock issuable pursuant to
    such provisions is indeterminate and is subject to adjustment depending on
    the future market price of the Common Stock. The actual number of shares of
    Common Stock offered hereby, and included in the Registration Statement of
    which this Prospectus is a part, include such additional number of shares of
    Common Stock as may be issued or issuable pursuant to such provisions. For
    purpose of estimating the number of shares of Common Stock to be included in
    this table, the Company calculated the number of shares issuable upon the
    exercise of such remedies as of October 2, 1998 (based upon a market price
    of $2.6625 which is 100% of the average of the daily closing prices of the
    Common Stock reported on the Nasdaq National Market for the five consecutive
    trading days preceding October 2, 1998).
 
(11) The number of shares set forth in the table represents an estimate of the
    number of shares of Common Stock to be offered by such Selling Stockholder
    upon conversion of, or issued in respect of, the Preferred Stock held by
    such Selling Stockholder, including 389,000 shares of Common Stock issuable
    pursuant to the exercise of warrants issued or issuable to the holder of
    such Preferred Stock and other shares of Common Stock which may be issuable
    to the holder of such Preferred Stock pursuant to the terms of the Preferred
    Stock. The actual number of shares of Common Stock issuable upon conversion
    of, or issued in respect of, Preferred Stock is indeterminate, is subject to
    adjustment and could be materially less or more than such estimated number
    depending on factors which cannot be predicted by the Company at this time,
    including, among other factors, the future market price of the Common Stock.
    The actual number of shares of Common Stock offered hereby, and included in
    the Registration Statement of which this Prospectus is a part, includes such
    additional number of shares of Common Stock as may be issued or issuable
    upon conversion of the Preferred Stock by reason of the floating rate
    conversion price mechanism or other adjustment mechanisms described therein,
    or by reason of any stock split, stock dividend or similar transaction
    involving the Common Stock, in order to prevent dilution, in accordance with
    Rule 416 under the Act. Pursuant to the terms of the Preferred Stock, if the
    outstanding Preferred Stock had been actually converted on September 8, 1998
    the conversion price would have been $5.14 (100% of the average of the daily
    closing bid prices of the Common Stock for the five consecutive trading days
    ending on the fifth trading day immediately preceding such date) at which
    price the outstanding Preferred Stock would have been converted into
    approximately 3,119,167 shares of Common Stock. Based on the closing price
    of the Common Stock on October 1, 1998 ($2.625) the outstanding Preferred
    Stock would have been converted into approximately 6,116,848 shares of
    Common Stock. On June 18, 1998, 2,500 shares of Preferred Stock were
    converted into 373,220 shares of Common Stock. Pursuant to the terms of the
    Preferred Stock, the shares of Preferred Stock are convertible by any holder
    only to the extent that the number of shares of Common Stock thereby
    issuable, together with the number of shares of Common Stock owned by such
    holder and its affiliates (but not including shares of Common Stock
    underlying unconverted shares of Preferred Stock), would not exceed 4.9% of
    the then outstanding Common Stock as determined in accordance with Section
    13(d) of the Exchange Act. Accordingly, the number of shares of Common Stock
    set forth in the table for this Selling Stockholder exceeds the number of
    shares of Common Stock that this Selling Stockholder could own beneficially
    at any given time through their ownership of the Series C Preferred Stock.
    In that regard, beneficial ownership of this Selling Stockholder set forth
    in the table is not determined in accordance with Rule 13d-3 under the
    Exchange Act. RGC International Investors, LDC is a party to an investment
    management agreement
 
                                       69
<PAGE>
    with Rose Glen Capital Management, L.P., a limited partnership of which the
    general partner is RGC General Partner Corp. Messrs. Wayne Block, Gary
    Kaminsky and Steve Katznelson own all of the outstanding capital stock of
    RGC General Partner Corp., and are parties to a shareholders' agreement
    pursuant to which they collectively control RGC General Partner Corp.
    Through RGC General Partner Corp., such individuals control Rose Glen
    Capital Management, L.P. Such individuals disclaim beneficial ownership of
    the Company's Common Stock owned by the Selling Shareholder.
 
(12) The number of shares set forth in the table represents an estimate of the
    number of shares of Common Stock to be offered by such Selling Stockholders
    upon conversion of the Convertible Notes held by such Selling Stockholders.
    The actual number of shares of Common Stock issuable upon conversion of the
    Convertible Notes is indeterminate, is subject to adjustment and could be
    materially less or more than such estimated number depending on factors
    which cannot be predicted by the Company at this time, including, among
    other factors, the future market price of the Common Stock. The actual
    number of shares of Common Stock offered hereby, and included in the
    Registration Statement of which this Prospectus is a part, include such
    additional number of shares of Common Stock as may be issued or issuable
    upon conversion of the Convertible Notes by reason of the floating rate
    conversion price mechanism, or by reason of any stock split, stock dividend
    or similar transaction involving the Common Stock, in order to prevent
    dilution, in accordance with Rule 416 under the Act. Pursuant to the terms
    of the Convertible Notes, if the Convertible Notes had been actually
    converted on October 2, 1998 the conversion price would have been $2.6625
    (100% of the average of the daily closing prices of the Common Stock
    reported on the Nasdaq National Market for the five consecutive trading days
    immediately preceding such date) at which price the Convertible Notes would
    have been converted into approximately 848,544 aggregate shares of Common
    Stock.
 
(13) Represents shares of Common Stock issuable pursuant to warrants issued or
    issuable to the Selling Stockholder.
 
(14) J. Alix & Associates was retained by the Company on November 2, 1997 to
    provide interim management services to the Company.
 
(15) Constitutes 25,000 shares underlying outstanding warrants exercisable by
    the Selling Stockholder.

                              PLAN OF DISTRIBUTION
 
    The Selling Stockholders, or their respective pledgees, donees, transferees
or other successors in interest, may sell some or all of the Shares in one or
more transactions (which may involve block transactions) on the Nasdaq National
Market or on such other market on which the Common Stock may from time to time
be trading, in privately negotiated transactions, through the writing of options
on the Shares, short sales or any combination thereof. The sale price to the
public may be the market price prevailing at the time of sale, a price related
to such prevailing market price or such other price as the Selling Stockholders
determine from time to time. The Shares may also be sold pursuant to Rule 144.
 
    The Selling Stockholders, or their respective pledgees, donees, tranferees
or other successors in interest, may also sell the Shares directly to market
makers acting as principals and/or broker/dealers, who may act as agent or
acquire the Shares as principal. Any broker/dealer participating in such
transactions as agent may receive a commission from the Selling Stockholders
(and, if they act as agent for the purchaser of such Shares, from such
purchaser). Usual and customary brokerage fees will be paid by the Selling
Stockholders. Broker/dealers may agree with the Selling Stockholders to sell a
specified number of Shares at a stipulated price per Share and, to the extent
such broker/dealer is unable to do so acting as agent for the Selling
Stockholders, to purchase as principal any unsold Shares at the price required
to fulfill the respective broker/dealer's commitment to the Selling
Stockholders. Broker/dealers who acquire Shares as principals may thereafter
resell such Shares from time to time in transactions (which may involve cross
and block transactions and which may involve sales to and through other
broker/dealers, including transactions of the nature described above) in the
over-the-counter market, in negotiated transactions or otherwise, at market
prices prevailing at the time of sale or at negotiated prices, and in connection
which such resales may pay to or receive commissions from the purchasers of such
Shares. If applicable, the Selling Stockholders also may have distributed or may
distribute Shares to one or more of their limited partners which are
unaffiliated with the Company; such limited partners may, in turn, distribute
such shares as described above. There can be no assurance that all or any of the
Shares offered hereby will be sold by the Selling Stockholders.
 
    The Company is bearing all costs relating to the registration of the Shares,
provided that any commissions or other fees payable to broker/dealers in
connection with any sale of the Shares will be borne by the Selling Stockholders
or other party selling such Shares. The Company has agreed to indemnify certain
of the Selling Stockholders, or their transferees or assignees, against certain
liabilities, including liabilities under the Act, or to contribute to payments
the Selling Stockholders, or their transferees or assignees, may be required to
make in respect thereof.
 
    The Selling Stockholders must comply with the requirements of the Act and
the Exchange Act and the rules and regulations thereunder in the offer and sale
of the Shares. In particular, during such times as the Selling Stockholders may
be deemed to be engaged in a distribution of the Common Stock, and therefore be
deemed to be an underwriter under the Act, it must comply with the Exchange Act,
as amended, and will, among other things:
 
        (a) not engage in any stabilization activities in connection with the
    Company's securities;
 
        (b) furnish each broker/dealer through which Shares may be offered such
    copies of this Prospectus, as amended from time to time, as may be required
    by such broker/dealer; and
 
        (c) not bid for or purchase any securities of the Company or attempt to
    induce any person to purchase any securities of the Company other than as
    permitted under the Exchange Act.
 
                                 LEGAL MATTERS
 
    The validity of the shares of the Company's Common Stock offered hereby will
be passed upon for the Company by Christopher J. Joyce, Esq., Senior Vice
President--Legal Affairs and Administration of the Company.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
 
  Medical Resources, Inc.
 
    We have audited the accompanying consolidated balance sheet of Medical
Resources, Inc. and Subsidiaries (the "Company") as of December 31, 1997 and the
consolidated statements of operations, stockholders' equity, and cash flows for
the years ended December 31, 1997 and 1995. Our audits also included the
financial statement schedule listed on page F-1 for the years then ended. These
financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Medical Resources, Inc. and Subsidiaries at December 31, 1997 and the
consolidated results of their operations and their cash flows for the years
ended December 31, 1997 and 1995, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedule referred to above, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein for 1997 and 1995.
 
    The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As more fully described in Note 2, the
Company incurred a net loss in 1997 and has a working capital deficiency at
December 31, 1997. In addition, the Company has not complied with certain
covenants of loan agreements. These conditions raise substantial doubt about the
Company's ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note 2. The financial statements do not
include any adjustments to reflect the possible future effects on the
recoverability and classification of assets or the amounts and classifications
of liabilities that may result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
    GENERAL
 
    Medical Resources, Inc., (herein referred to as "MRI" and collectively with
its subsidiaries, affiliated partnerships and joint ventures, referred to herein
as the "Company") specializes in the operation and management of diagnostic
imaging centers. The Company operates and manages primarily fixed-site,
free-standing outpatient diagnostic imaging centers (herein referred to as
"centers"), and provides diagnostic imaging network management services to
managed care providers. The Company's diagnostic imaging segment also develops
and sells radiology industry information systems through its subsidiary, Dalcon
Technologies, Inc.
 
    Through the Per Diem and Travel Nursing Divisions of its wholly-owned
subsidiaries, StarMed Staffing, Inc. and Wesley Medical Resources Inc.
("StarMed"), the Company provides temporary healthcare staffing of registered
nurses and other medical personnel to acute and sub-acute care facilities
nationwide. On August 18, 1998, the Company sold the stock of StarMed to
RehabCare Group, Inc. for gross proceeds of $33,000,000 (the "StarMed Sale").
Due to the StarMed Sale, the results of operations of StarMed are herein
reflected in the Company's Consolidated Statements of Operations as discontinued
operations. See Note 16 of Notes to Consolidated Financial Statements.
 
    During July 1998, the Company's shareholders approved a reverse stock split
of the Company's outstanding shares of Common Stock. As a result of the reverse
stock split, each three outstanding shares of Common Stock were automatically
converted into one share of new Common Stock. The Company effected the reverse
stock split in order to meet the minimum bid price requirement for continued
listing on the Nasdaq Stock Market. The share data included herein have been
adjusted to reflect the impact of the reverse stock split.
 
    CONSOLIDATION
 
    The accompanying consolidated financial statements include the accounts of
MRI, its wholly-owned subsidiaries, majority-owned joint ventures and limited
partnerships in which the Company is a general partner. All material
intercompany balances and transactions have been eliminated. As general partner,
the Company is subject to all the liabilities of a general partner and as of
December 31, 1997, is entitled to share in partnership profits, losses and
distributable cash as provided in the partnership agreements. The limited
partnership interests are shown in the accompanying financial statements as
minority interest. Under certain of the partnerships, the Company also is paid a
monthly management fee based on patient cash collections and/or patient volume
under management agreements. Partnership losses allocable to limited partners in
excess of their respective capital accounts are charged to the Company as
general partner. Future income related to such partnerships will be allocated to
the Company as general partner until such time as the Company has recovered the
excess losses. Certain of the limited partnership agreements require limited
partners to make cash contributions in the event their respective capital
accounts are reduced below zero due to partnership operating losses. The Company
has not reflected this potential recovery from the limited partners due to
uncertainty regarding the ultimate receipt of the cash contributions.
 
    REVENUE RECOGNITION
 
    At each of the Company's diagnostic imaging centers, all medical services
are performed exclusively by physician groups (the "Physician Group" or the
"Interpreting Physician"), generally consisting of

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
radiologists with whom the Company has entered into independent contractor
agreements. Pursuant to these agreements, the Company has agreed to provide
equipment, premises, comprehensive management and administration, including
responsibility for billing and collection of receivables, and technical imaging
services to the Interpreting Physician.
 
    Net service revenues are reported, when earned, at their estimated net
realizable amounts from patients, third party payors and others for services
rendered at contractually established billing rates which generally are at a
discount from gross billing rates. Known and estimated differences between
contractually established billing rates and gross billing rates ("contractual
allowances") are recognized in the determination of net service revenues at the
time services are rendered. Subject to the foregoing, the Company's imaging
centers recognize revenue under one of the three following types of agreements
with Interpreting Physicians:
 
        TYPE I--The Company receives a technical fee for each diagnostic imaging
    procedure performed at a center, the amount of which is dependent upon the
    type of procedure performed. The fee included in revenues is net of
    contractual allowances. The Company and the Interpreting Physician
    proportionally share in any losses due to uncollectible amounts from
    patients and third party payors, and the Company has established reserves
    for its share of the estimated uncollectible amount.
 
        TYPE II--The Company bills patients and third party payors directly for
    services provided and pays the Interpreting Physicians either (i) a fixed
    percentage of fees collected at the center, or (ii) a contractually fixed
    amount based upon the specific diagnostic imaging procedures performed.
    Revenues are recorded net of contractual allowances and the Company accrues
    the Interpreting Physicians fee as an expense on the Consolidated Statements
    of Operations. The Company bears the risk of loss due to uncollectible
    amounts from patients and third party payors, and the Company has
    established reserves for the estimated uncollectible amount.
 
        TYPE III--The Company receives from an affiliated physician association
    a fee for the use of the premises, a fee per procedure for acting as billing
    and collection agent and a fee for administrative and technical services
    performed at the centers. The affiliated physician association contracts
    with and pays directly the Interpreting Physicians. The Company's fee, net
    of an allowance based upon the affiliated physician association's ability to
    pay after the association has fulfilled its obligations (i.e., estimated
    future net collections from patients and third party payors less facility
    lease expense and Interpreting Physicians fees), constitutes the Company's
    net service revenues. Since the Company's net service revenues are dependent
    upon the amount ultimately realized from patient and third party
    receivables, the Company's revenue and receivables have been reduced by an
    estimate of patient and third party payor contractual allowances, as well as
    an estimated provision for uncollectible amounts from patients and third
    party payors.
 
    Revenues derived from Medicare and Medicaid are subject to audit by such
agencies. The Company is not aware of any pending audits.
 
    The Company also recognizes revenue from the sale of radiology information
systems. Such revenues are recognized on an accrual basis as earned.
 
    RECLASSIFICATION
 
    Certain prior year items have been reclassified to conform to the current
year presentation.

    USE OF ESTIMATES
 
    The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of revenues, expenses, assets
and liabilities, and the disclosure of contingent assets and liabilities in the
consolidated financial statements and accompanying notes. The most significant
estimates relate to contractual allowances, the allowance for doubtful accounts
receivable, income taxes, contingencies and the useful lives of equipment. In
addition, healthcare industry reforms and reimbursement practices will continue
to impact the Company's operations and the determination of contractual and
other allowance estimates. Actual results could differ from management's
estimates.
 
    CASH AND CASH EQUIVALENTS
 
    For financial statement purposes cash equivalents include short-term
investments with an original maturity of ninety days or less. Restricted cash
consists of amounts held pursuant to the terms of letters of credit and is
classified based upon the expiration of the restriction.
 
    SHORT-TERM INVESTMENTS
 
    At December 31, 1996 the Company's short-term investments, consist of
certificates of deposits and treasury bills with maturities between three and
twelve months. Such securities are classified as available-for-sale. Securities
available for sale are carried at fair value with unrealized gains and losses,
net of tax, reported as a separate component of shareholders' equity. Any
realized gains and losses are determined on the specific identification method.
 
    Restricted short-term investments at December 31, 1996 consist of $4,500,000
of United States Government obligations held pursuant to a letter of credit
issued in connection with one of the Company's acquisitions. The letter of
credit served to reserve consideration for the acquisition in the event that the
shares of the Company's Common Stock issued to the seller were not registered
within 60 days of the closing of the sale. During 1997, the shares were
registered within the specified timeframe of the agreement, and as such, the
restriction of the investment was removed.
 
    INVESTMENTS IN JOINT VENTURES AND LIMITED PARTNERSHIPS
 
    The minority interests in the equity of consolidated joint ventures and
limited partnerships, which are not material, are reflected in the accompanying
consolidated financial statements. Investments by the Company in joint ventures
and limited partnerships over which the Company can exercise significant
influence but does not control are accounted for using the equity method.
 
    The Company suspends recognition of its share of joint ventures losses in
entities in which it holds a minority interest when its investment is reduced to
zero. The Company does not provide for additional losses unless, as a partner or
joint venturer, the Company has guaranteed obligations of the joint venture or
limited partnership.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment procured in the normal course of business is stated
at cost. Property and equipment purchased in connection with an acquisition is
stated at its estimated fair value, generally based

on an appraisal. Property and equipment is depreciated for financial accounting
purposes using the straight-line method over the shorter of their estimated
useful lives, generally five to seven years, or the term of a capital lease, if
applicable. Leasehold improvements are being amortized over the shorter of the
useful life or the remaining lease term. Expenditures for maintenance and
repairs are charged to operations as incurred. Renewals and betterments are
capitalized.
 
    GOODWILL AND OTHER INTANGIBLE ASSETS
 
    The excess of purchase price of businesses over the fair value of assets
acquired is recorded as goodwill and is amortized on a straight line basis
generally over twenty years. Other intangible assets consist of covenants not to
compete, value of managed care contracts, organizational costs and capitalized
lease costs related to acquired businesses and are amortized on a straight line
basis over their respective initial estimated lives of three to ten years. Gross
intangible assets and related accumulated amortization are as follows (in
thousands):

    Amortization expense from continuing operations for goodwill was $5,626,000,
$1,039,000 and $161,000 in 1997, 1996 and 1995, respectively. Amortization
expense for other intangibles was $1,151,000, $506,000 and $337,000 in 1997,
1996 and 1995, respectively.
 
    The Company periodically reviews goodwill to assess recoverability based
upon expectations of undiscounted cash flows and operating income of each entity
having a material goodwill balance. An impairment would be recognized in
operating results, if the sum of the expected future cash flows (undiscounted
and without interest charges) is less than the carrying value of the related
costs in excess of net assets acquired. The amount of the impairment would be
measured by comparing the carrying value of intangible and other long-lived
assets to their fair values. See discussion of 1997 impairment loss in Note 3 of
the Notes to Consolidated Financial Statements.
 
    EARNINGS PER SHARE
 
    Effective for the year ended December 31, 1997, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share." The adoption of SFAS No. 128 requires the presentation of Basic Earnings
per Share and Diluted Earnings per Share. Basic earnings per share is based on
the weighted average number of common shares outstanding during the year.
Diluted earnings per share is based on the weighted average number of common
shares outstanding during the year plus the

1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    STOCK OPTIONS
 
    SFAS No. 123, Accounting for Stock-Based Compensation requires the Company
to choose between two different methods of accounting for stock options. The
Statement defines a fair-value-based method of accounting for stock options but
allows an entity to continue to measure compensation cost for stock options
using the accounting prescribed by APB Opinion No. 25, Accounting for Stock
Issued to Employees (APB No. 25). The Company has elected to continue using the
accounting methods prescribed by APB No. 25 and will disclose the amount of the
proforma compensation expense, required to be disclosed under the SFAS No. 123.
See disclosure in Note 9 of the Notes to the Consolidated Financial Statements.
 
    INCOME TAXES
 
    The Company accounts for income taxes under SFAS No. 109, Accounting for
Income Taxes. Under the asset and liability method of SFAS No. 109, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. Under SFAS No. 109, the effect on deferred tax assets
and liabilities of a change in tax rates is recognized in income in the period
that includes the enactment date. As of December 31, 1997, the Company has
provided a valuation reserve against a portion of its net deferred income tax
assets due to uncertainty regarding the ultimate recovery of such deferred
income tax assets. See further discussion in Note 10 of the Notes to the
Consolidated Financial Statements.
 
    RECENT ACCOUNTING PRONOUNCEMENTS
 
    SFAS No. 130, "Reporting Comprehensive Income", requires an entity to report
comprehensive income and its components for fiscal years beginning after
December 15, 1997. This new standard increases financial reporting disclosures,
but will have no impact on the Company's financial position, cash flows or
results of operations.
 
    Statement Of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use", requires an entity to expense all
software development costs incurred in the preliminary project state, training
costs and data conversion costs for fiscal years beginning after December 15,
1998. The Company believes that this statement will not have a material effect
on the Company's accounting for computer software acquisition cost.
 
    Statement Of Position 97-2, "Consolidation of Physicians' Practice
Entities", requires an entity to consolidate Physicians' Practice Entities in
circumstances in which substantial control is exercised by the Company. The
Company believes that this statement will not have a material effect on the
Company's financial position, cash flows or results of operations.
 
2. BASIS OF FINANCIAL STATEMENT PRESENTATION AND ISSUES AFFECTING LIQUIDITY
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company is currently in default of certain financial
covenants under the agreements for its $78,000,000 of Senior Notes. Management
and the Senior Note lenders are engaged in discussions to resolve this matter.
In the event the parties are unable to reach agreement, the lenders are
entitled, at their discretion, to

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. BASIS OF FINANCIAL STATEMENT PRESENTATION AND ISSUES AFFECTING LIQUIDITY
(CONTINUED)
exercise certain remedies including acceleration of repayment. There can be no
assurance that the Senior Note lenders will provide the Company with an
amendment or waiver of the defaults. In addition, certain medical equipment
notes, and operating and capital leases of the Company, aggregating $16,685,000
at December 31, 1997 (the "Cross-Default Debt"), contain provisions which allow
the creditors or lessors to accelerate their debt or terminate their leases and
seek certain other remedies if the Company is in default under the terms of
agreements such as the Senior Notes.
 
    In the event that the Senior Note lenders or the holders of the Cross
Default Debt elect to exercise their right to accelerate the obligations under
the Senior Notes or the other loans and leases, such acceleration would have a
material adverse effect on the Company, its operations and its financial
condition. Furthermore, if such obligations were to be accelerated, in whole or
in part, there can be no assurance that the Company would be successful in
identifying or consummating financing necessary to satisfy the obligations which
would become immediately due and payable. As a result of the uncertainty related
to the defaults and corresponding remedies described above, the Senior Notes and
the Cross Default Debt were shown as current liabilities on the Company's
Consolidated Balance Sheets at December 31, 1997. Accordingly, the Company had a
deficit in working capital of $58,174,000 at December 31, 1997. These matters
raise substantial doubt about the Company's ability to continue as a going
concern. In addition to continuing to negotiate with the Senior Note lenders in
an attempt to obtain waivers or amendments of the aforementioned defaults, the
Company has taken various actions in response to this situation, including the
following: (i) it effected a workforce reduction in March 1998 aimed at reducing
the Company's overall expense levels and (ii) it has retained the investment
banking firm of SBC Warburg Dillon Read to assist the Company in exploring a
possible sale of the Company's StarMed temporary staffing subsidiary (see Note
16 of Notes to Consolidated Financial Statements for further discussion). The
financial statements do not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    See Note 16 of Notes to Consolidated Financial Statements for further
discussion.
 
3. LOSS ON IMPAIRMENT OF GOODWILL AND OTHER LONG-LIVED ASSETS AND OTHER UNUSUAL
CHARGES
 
    During the fourth quarter of 1997, the Company recorded a $12,962,000 loss
on the impairment of goodwill and other long-lived assets. This loss consists of
the write-off of goodwill of $10,425,000, covenants not to compete of $118,000
and fixed assets of $2,419,000. The write-down of fixed assets primarily relates
to imaging equipment. Primarily the entire impairment relates to eight of the
Company's diagnostic imaging centers that are under-performing. The Company has
recorded impairment losses for these centers because the sum of the expected
future cash flows, determined based on an assumed continuation of current
operating methods and structures, does not cover the carrying value of the
related long-lived assets.
 
    During the fourth quarter of 1997, the Company also recorded $9,723,000 of
other unusual charges consisting of (i) $3,256,000 for the estimated net costs
associated with the resolution of the shareholder and employee lawsuits (see
discussion of litigation in Note 11 of the Notes to the Consolidated Financial
Statements), (ii) $2,243,000 for higher than normal professional fees, (iii)
$2,169,000 ($2,051,000 of which was a non-cash charge related to the issuance of
272,000 warrants) for penalties associated with delays in the registration of
the Company's common stock issued in connection with acquisitions or issuable
upon conversion of convertible preferred stock, (iv) $1,150,000 for the loss on
investment related to a potential

acquisition not consummated, (v) $469,000 for costs associated with the
investigation of related party transactions which was concluded in April 1998
and (vi) $436,000 for management termination benefits and related costs. The
Company accrues for legal fees as incurred.
 
    The Company expects to incur additional unusual charges of at least
$4,500,000 during 1998 primarily related to the estimated net costs associated
with the resolution of the shareholder and employee lawsuits, penalties
associated with delays in the registration of the Company's Common Stock and
costs associated with the investigation of related party transactions. Such
additional unusual charges could be substantially higher depending upon the
ultimate outcome of current negotiations regarding penalties associated with
failure to register the Company's Common Stock and the outcome of certain
litigation. See further discussion in Note 11 of the Notes to the Consolidated
Financial Statements.

    Accounts receivable is net of contractual allowances which represent
standard fee reductions negotiated with certain third party payors. Contractual
allowances amounted to approximately $93,490,000, $25,270,000 and $13,375,000
for the years ended December 31, 1997, 1996 and 1995, respectively.
 
    The Company's receivables relate to a variety of different structures (see
discussion of revenue recognition in Note 1 of the Notes to Consolidated
Financial Statements) as well as a variety of payor classes, including third
party medical reimbursement organizations, principally insurance companies.
Approximately 24.2% and 19.5% of the Company's 1997 and 1996 imaging revenues
was derived from the delivery of services with respect to the timing of payment
is substantially contingent upon the timing of settlement of pending litigation
involving the recipient of services and third parties (Personal Injury Type
accounts receivable). The Company undertakes certain measures to identify and
document the individual's obligation to pay for services rendered regardless of
the outcome of the pending litigation. By its nature, the realization of a
substantial portion of these receivables is expected to extend beyond one year
from the date the service was rendered. The Company anticipates that a material
amount of its Personal Injury Type accounts receivable will be outstanding for
periods in excess of twelve months in the future. The Company considers the
aging of its accounts receivable in determining the amount of allowance for

    During 1997, the Company borrowed $78,000,000 of Senior Notes (the "Senior
Notes") from a group of insurance companies led by the John Hancock Mutual Life
Insurance Company ("John Hancock"). The notes bear interest at an average annual
rate of 7.87%, are subject to annual sinking fund payments commencing February
2001 and have a final maturity in February 2005. The Senior Notes are guaranteed
by substantially all of the Company's diagnostic imaging subsidiaries and
collateralized by certain partnership interests owned through subsidiaries by
the Company. In addition, the agreement relating to the issuance of the Senior
Notes imposes certain affirmative and negative covenants on the Company and its
restricted subsidiaries, including restrictions on the payment of dividends. The
Company used a portion of the proceeds from the Senior Notes to retire capital
lease obligations totaling $8,274,000 and notes payable totaling $5,490,000. The
difference between the amount used to retire capital lease obligations and the
carrying value of such obligations was approximately $1,461,000. In accordance

        In 1994, StarMed and a creditor renegotiated a note payable. At the time
    of the restructuring, the note balance was adjusted to the amount of the
    projected undiscounted future cash payments based upon the prevailing
    interest rate and, accordingly, no interest expense has been recorded
    subsequent to the effective date of the renegotiation other than the amounts
    attributed to a change in the variable rate and is due in 2000. The balance
    of such note at December 31, 1997 was $3,042,000.

8. DEBT (CONTINUED)
    On February 7, 1996, the Company issued at par $6,533,000 aggregate
principal amount of 10.5% Convertible Subordinated Debentures due 2001 (the
"1996 Debentures"). The Company called for the redemption of the 1996 Debentures
at the conversion price of $18.00 per share on or before March 27, 1997. As of
December 31, 1997, all of the 1996 Debentures have been converted. On May 30,
1995, the Company issued at par $4,350,000 aggregate principal amount of 11%
Convertible Subordinated Debentures due 2000 (the "1995 Debentures"). The 1995
Debentures automatically converted to Common Stock when, on June 20, 1997 the
market price of the Stock exceeded $18.00 per share for a 15 consecutive day
period. Under the terms of the merger agreement with NMR, the Company assumed
the obligations under NMR's 8% Convertible Subordinated Debentures due 2001
including payment of principal and interest (the "NMR Debentures"). The Company
called for redemption of the NMR Debentures at the conversion price of $19.62
per share on or before March 27, 1997. As of December 31, 1997, all of the NMR
Debentures had either been redeemed or converted into Common Stock of the
Company. During 1997 and 1996, debentures of $6,988,000 and $5,735,000,
respectively, were converted into Common Stock.
 
    In connection with the private placements of the 1995 Debentures and the
1996 Debentures, the Company paid $248,000 and $357,000, respectively, in
placement agent fees and expenses to an investment banking firm. Mr. Gary L.
Fuhrman, a director of the Company, is an executive officer and director of such
investment banking firm.
 
    Aggregate maturities (after classification of certain amounts as current due
to the financial covenant defaults) of the Company's Senior Notes and other
notes and mortgages payable for years 1998 through 2002 and thereafter are as
follows (in thousands):

    The Company has three revolving lines of credit from a third party financing
corporation totaling $12,000,000. The lines bear interest at prime plus 1.5%
(10% at December 31, 1997) and have a two-year term. As of December 31, 1997 and
1996, no amounts were outstanding under these lines of credit.
 
    On December 29, 1997, the Company entered into a $15 million credit facility
with DVI Financial Services Inc. (the "Facility"). The Facility provides for two
advances to the Company, one for $8 million and the other for $7 million. In
consideration for making the Facility available to the Company, the lender
received warrants to purchase an aggregate of 33,333 shares of Common Stock at
an exercise price based upon 110% of the average market prices over a period
prior to the issuance of the warrants. In the event that the lender refuses to
make the second advance, warrants to purchase 15,556 shares of Common Stock will
be canceled. As of December 31, 1997, $8,000,000 had been borrowed under the
Facility.
 
    During 1997, StarMed obtained a revolving line of credit from a third party
financing corporation. The $6,000,000 line bears interest at a rate of prime
plus 1.5% (10% at December 31, 1997), has a two year term and is collateralized
by substantially all of StarMed's accounts receivable. At December 31, 1997,
$3,744,000 was outstanding under the line. In early 1998, StarMed increased the
availability under the revolving line of credit by $1,000,000.

9. STOCKHOLDERS' EQUITY
 
    AUTHORIZED STOCK
 
    The authorized capital stock of the Company consists of 50,000,000 shares of
Common Stock, par value $.01 per share, and 100,000 shares of Preferred Stock,
par value $.01 per share ("Preferred Stock"). The Company has a Shareholders'
Rights Plan (described below) which requires the issuance of Series C Junior
Participating Preferred Stock, in connection with the exercise of certain stock
purchase rights. At December 31, 1997, there was (i) 7,296,333 shares of Common
Stock issued and outstanding and, (ii) 18,000 shares of Series C Convertible
Preferred Stock outstanding (the "Convertible Preferred Shares").
 
    SHAREHOLDERS' RIGHTS PLAN
 
    Pursuant to the Shareholders' Rights Plan, holders of the Common Stock
possess three rights (the "Rights") to purchase one ten thousandth of a share of
Series C Junior Participating Preferred Stock for each share of Common Stock
owned. The Rights will generally become exercisable ten days after a person or
group acquires 15% of the Company's outstanding voting securities or ten
business days after a person or group commences or announces an intention to
commence a tender or exchange offer that could result in the acquisition of 15%
of any such securities. Ten days after a person acquires 15% or more of the
Company's outstanding voting securities (unless this time period is extended by
the Board of Directors) each Right would, subject to certain adjustments and
alternatives, entitle the rightholder to purchase Common Stock of the Company or
stock of the acquiring company having a market value of twice the $24.00
exercise price of the Right (except that the acquiring person or group and other
related holders would not be able to purchase common stock of the Company on
these terms). The Rights are nonvoting, expire in 2006 and may be redeemed by
the Company at a price of $.001 per Right at any time prior to the tenth day
after an individual or group acquired 15% of the Company's voting stock, unless
extended.
 
    The purpose of the Rights is to encourage potential acquirers to negotiate
with the Company's Board of Directors prior to attempting a takeover and to give
the Board leverage in negotiating on behalf of the shareholder the terms of any
proposed takeover.
 
    CONVERTIBLE PREFERRED STOCK
 
    In July 1997, the Company issued 18,000 shares of $1,000 Series C
Convertible Preferred Stock, $.01 par value, to RGC International, LDC ("RGC").
The Convertible Preferred Shares are convertible into Common Stock of the
Company at the option of RGC beginning on the date on which a registration
statement relating to the Common Stock underlying the Convertible Preferred
Shares (the "Conversion Shares") is declared effective by the Securities and
Exchange Commission, provided that, beginning 180 days from the effectiveness of
such registration statement, the Company may require the conversion of all or a
portion of the Convertible Preferred Shares.
 
    The Convertible Preferred Shares convert into the Company's Common Stock by
dividing the Stated Value of the Convertible Preferred Shares, plus 3% per annum
to the date of conversion, by the lesser of (i) $62.10 and (ii) the average of
the daily closing bid prices for the Company's Common Stock for the five (5)
consecutive trading day period ending five (5) trading days prior to the date of
conversion. If the average closing price of the Company's Common Stock (the
"Closing Price") for any ten (10) consecutive trading days does not exceed
$36.75 (the "Floor Price"), the Company has the right to block conversion of the
Convertible Preferred Shares by RGC for up to thirty (30) days in the aggregate.
Effective May 1998,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
9. STOCKHOLDERS' EQUITY (CONTINUED)
in exchange for certain concessions with respect to penalties, the Company
waived the above-described right to block conversion. If the Closing Price does
not exceed the Floor Price for 30 consecutive calendar days, the Convertible
Preferred Shares are redeemable, in whole or in part, at the option of the
Company for 110% of the stated value plus 3% per annum. RGC is subject to volume
restrictions which prohibit the sale of more than 25% of the daily or weekly
trading volume in any such period, unless certain circumstances exist. The
liquidation preference of each Convertible Preferred Share is $1,000 plus 3% per
annum. The holder of the Convertible Preferred Shares is entitled to limited
voting rights.
 
    As of December 31, 1997, based upon the current market price of the
Company's Common Stock, the Convertible Preferred Shares would be convertible
into 648,000 shares of Company Common Stock, representing 8% of the outstanding
shares of Common Stock as of such date after giving effect to the conversion of
the Convertible Preferred Shares. Under the terms of the Convertible Preferred
Shares, RGC is not permitted to convert Shares of the Convertible Preferred
Shares which would result in RGC owning in excess of 5% of the outstanding
shares of Common Stock. As discussed above, the Company has the option to
repurchase the shares at 110% of stated value plus 3% per annum.
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement (the "Series C Preferred Stock Purchase Agreement"), dated July 21,
1997, between the Company and RGC, and the Registration Rights Agreement, dated
July 21, 1997, (the "Series C Registration Rights Agreement"), between the
Company and RGC (the Series C Stock Purchase Agreement and the RGC Registration
Rights Agreement are hereinafter referred to as the "RGC Agreements"), the
Company was required to use its best efforts to include the shares of Common
Stock issuable upon conversion of the Convertible Preferred Stock (the "RGC
Conversion Shares") in an effective Registration Statement on Form S-3 not later
than October 1997. The RGC Agreements provide for monthly penalties ("RGC
Registration Penalties") in the event that the Company fails to register the
Conversion Shares prior to October 1997 with such penalties continuing until
such time as the Conversion Shares are registered as required by the RGC
Agreements.
 
    As a result of the Company's failure to register the RGC Conversion Shares
at various dates on or after December 31, 1997, the Company: (i) in lieu of RGC
Registration Penalties accruing on or before December 31, 1997, issued in
December 1997 warrants to RGC to acquire 272,333 shares of Common Stock at an
exercise price of $34.86 per share (such warrants were recorded as a 1997
expense and had an estimated value for accounting purposes of $2,051,000); (ii)
in lieu of RGC Registration Penalties accruing during the month of January 1998,
issued warrants to RGC to acquire 116,667 shares of Common Stock at an exercise
price of $38.85 per share (such warrants having an estimated value for
accounting purposes only of $1,194,000); and (iii) in lieu of RGC Registration
Penalties accruing from February 1, 1998 to April 30, 1998, issued to RGC
interest bearing promissory notes (the "RGC Penalty Notes"), in the aggregate
principal amount of $1,440,000. The value of the warrants issued to RGC was
determined for accounting purposes using the Black-Scholes option pricing model
using the following assumptions: dividend yield 0%; expected volatility 62%;
expected life of one and one-half years and a risk-free interest rate of 5.6%.
On May 1, 1998, as a result of the Company's failure to register the Conversion
Shares on or before such date, RGC was entitled under the RGC Agreements to
demand a one-time penalty of $1,800,000 (the "May 1998 Penalty") payable, at the
option of RGC, in cash or additional shares of Common Stock. As of May 26, 1998,
RGC had not demanded payment or other satisfaction of the May 1998 Penalty.

9. STOCKHOLDERS' EQUITY (CONTINUED)
    On May 1, 1998, the Company did not pay RGC the $1,440,000 that was then due
and payable under the RGC Penalty Notes. Additionally, as a result of the
Company's continuing failure to register the Conversion Shares, RGC is entitled
to additional penalties of $540,000 per month (payable at the option of RGC in
cash or additional shares of Common Stock). The Company and RGC are currently in
discussions regarding the restructuring of the Penalty Notes, the May 1998
Penalty and the on-going monthly penalties, but there can be no assurance that
the Company will be successful in restructuring such obligations on terms
favorable to the Company or its shareholders.
 
    STOCK OPTIONS AND EMPLOYEE STOCK GRANTS
 
    Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("SFAS No. 123"), was issued in October 1995,
establishing a fair value-based method of accounting for stock-based
compensation plans, including stock options and stock purchase plans. SFAS No.
123 allows companies to adopt a fair-value-based method of accounting for
stock-based compensation plans or, at their option, to retain the
intrinsic-value based method of Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB No. 25"), and supplement it
with pro forma disclosures of net earnings and earnings per share data as if the
fair value method had been applied. The Company has elected to continue to
account for stock-based compensation plans under APB No. 25 and, as such, the
adoption of this standard has not impacted the consolidated results of earnings
or financial condition.
 
    The Company's five stock option plans provide for the awarding of incentive
and non qualified stock options to employees, directors and consultants who may
contribute to the success of the Company. The options granted vest either
immediately or ratably over a period of time from the date of grant, typically
three or four years, at a price determined by the Board of Directors or a
committee of the Board of Directors, generally the fair value of the Company's
Common Stock at the date of grant. Options granted to consultants are accounted
for based on the fair value of the options issued.
 
    During 1996 and the first quarter of 1997, options were granted to employees
under stock option plans which were approved by the Company's Shareholders in
May 1997. The difference between the exercise price of the options and the
market price of the Company's Common Stock on the date of plan approval resulted
in compensation aggregating $3,381,000. The 1997 expense of $2,536,000
representing the portion of such options vested in 1997 is included as stock
based compensation expense in the accompanying Consolidated Statements of
Operations. The remaining balance of $845,000 will be recognized ratably over
the remaining vesting period of the options. In the following tables, these
options are treated as if they were granted on the date of the plan approvals in
May 1997.
 
    Options to purchase 580,313 shares of the Company's Common Stock granted to
employees of the Company in 1997 under an option plan (the "1997 Plan") have
lapsed and are not deemed to have been granted due to the fact that the 1997
Plan was not presented for approval to the Company's Stockholders within one
year of such plan's approval by the Board of Directors of the Company.
 
    Had the fair-value based method of accounting been adopted to recognize
compensation expense for the above plans (excluding the 1997 Plan), the
Company's net earnings and earnings per share would have

    For services rendered by a financial advisory company owned by the Chairman
of the Board (the "Affiliate") in connection with several acquisitions, the
Company issued warrants (the "Acquisition Warrants") to purchase shares of the
Company's Common Stock at exercise prices equal to the market price of the
Company's Common Stock on the date of issuance. The fair value of such warrants
was considered part of the purchase price of the related acquisition, and was
determined (for accounting purposes only) using the Black-Scholes option pricing
model using the following assumptions: Dividend yield 0%; expected volatility
62%; Expected life three to five years and a risk free interest rate of 5.6% as
set forth below. The Acquisition Warrants are exercisable at prices ranging from
$30.93 to $37.77 per share. As of May 26, 1998, none of the Acquisition Warrants
had been exercised, and the closing sale price of the Common Stock was $9 3/16.
 
        Warrants issued in connection with the acquisition of a diagnostic
    imaging center located in Jacksonville, Florida to purchase 10,667 shares of
    the Company's Common Stock at an exercise price of $30.93 per share. The
    warrants have a term of three years, are exercisable from the date of grant
    and have an estimated fair value (for accounting purposes only) of $150,000.
 
        Warrants issued in connection with the acquisition of Advanced
    Diagnostic Imaging, Inc. to purchase 45,667 shares of the Company's Common

    purposes only) of $276,000.
 
        Warrants issued in connection with the acquisition of ATI Centers, Inc.
    to purchase 56,000 shares of the Company's Common Stock at an exercise price
    of $33.18 per share. The warrants have a term of three years, are
    exercisable from the date of grant and have an estimated fair value (for
    accounting purposes only) of $847,000.
 
        Warrants issued in connection with the acquisition of a diagnostic
    imaging center located in Rancho Cucamonga, California to purchase 18,333
    shares of the Company's Common Stock at an exercise price of $33.75 per
    share. The warrants have a term of three years, are exercisable from the
    date of grant, and have an estimated fair value (for accounting purposes
    only) of $282,000.
 
        Warrants to purchase 22,000 and 53,333 of the Company's Common Stock at
    an exercise price of $37.77 per share were granted in connection with the
    acquisition of diagnostic imaging centers in Maryland, and from Capstone
    Management, Inc., respectively. The warrants have a term of five years and
    are exercisable from the date of grant. The estimated fair value (for
    accounting purposes only) of $478,000 and $1,158,000, respectively.
 
    Effective December 30, 1997, the Company issued warrants to RGC to purchase
272,333 shares of the Company's Common Stock with an exercise price of $34.86
per share. These warrants have a term of five years and are exercisable from the
date of grant. The warrants had an estimated fair value of $2,051,000. The fair
value of such warrants was estimated using the Black-Scholes option pricing
model using the following assumptions: Dividend yield 0%, Expected volatility
62%, Expected life one year and a risk free interest rate of 5.50% based upon
the expected life of the warrants.
 
    In December 1997, the Company granted warrants to a financing company in
connection with a line of credit entered into by the Company. The warrants to
purchase 17,778 shares of the Company's Common Stock at an exercise price of
$28.62 per share have a term of seven years and are exercisable from the date of
grant. The warrants had an estimated fair value of $337,000 which was recorded
as a deferred financing expense and is being amortized as additional interest
over the term of the facility. The fair value of each warrant was estimated
using the Black-Scholes option pricing model using the following assumptions:
Dividend yield 0%, Expected volatility 62%, Expected life seven years and a risk
free interest rate of 5.63% based on the expected life of the warrants.
 
    For warrants granted during 1996, the fair value of each stock purchase
warrant issued has been accounted for as a component of each transaction's
purchase price and the value has been estimated on the date of grant using the
Black-Scholes option pricing model based on the following assumptions: dividend
yield--0%, expected volatility--52% and an expected life of 2 years, unless
otherwise noted.
 
    In March 1996 a financial consulting firm doing business with the Company
was granted warrants to purchase 25,000 shares of the Company's Common Stock
consisting of 12,500 warrants with an exercise price of $24.00 per share and
12,500 warrants with an exercise price of $36.00 per share. These warrants have
a term of five years and are exercisable from date of grant. The number of such
warrants was subsequently increased by 1,562 with an exercise price of $24.00
per share and 1,562 warrants with an exercise price of $36.00 per share. As of
December 31, 1997, warrants to purchase 14,062 shares of the Company's Common
Stock at $24.00 a share and 14,062 at $36.00 per share were outstanding. The
warrants had an estimated fair value of $60,000. The fair value of each warrant
was estimated using the

    The Company's existing deferred tax assets at December 31, 1997 have been
reduced by a valuation allowance of $10,700,000, due to the uncertainty
regarding the realization of the full amount of such deferred tax assets. The
valuation allowance represents the amount required to reduce all deferred income
tax assets to an amount representing the expected federal income tax loss
carryback available to the Company.
 
    At December 31, 1997, the Company has available federal net operating loss
carryforwards of approximately $8,028,000 expiring in years 1999 through 2009.
 
    Utilization of the Company's tax net operating losses is limited to the
separately determined taxable incomes of certain of its subsidiaries. In
addition, the Tax Reform Act of 1986 enacted a complex set of rules ("Section
382") limiting the utilization of net operating loss carryforwards in periods
following a corporate ownership change. In general, a corporate ownership change
is deemed to occur if the percentage of stock of a loss corporation owned
(actually, constructively and in certain cases deemed owned) by one or more "5%
shareholders" has increased by 50 percentage points over the lowest percentage
of such stock owned during a specified testing period (generally a three year
period). The utilization of the Company's available net operating loss
carryforwards is subject to such limitations. Should the Company experience
further ownership changes, its ability to utilize the available federal net
operating loss carryforwards could be subject to further limitation.

    The Company also has available tax credit carryforwards of approximately
$385,000 expiring between 1998 and 2011. The utilization of such credits is also
subject to a limitation similar to the net operating loss limitation described
above.
 
    At December 31, 1997, the Company had income taxes recoverable of $6,504,000
which represents estimated 1997 income tax payments made during 1997 that the
Company will be refunded upon filing of its 1997 tax return.

11. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    In connection with certain of the Company's acquisitions, the Company
entered into agreements for the sale and leaseback of medical diagnostic
equipment. Included in future minimum lease payments listed above are $1,782,000
for each of the years 1998, 1999, 2000, 2001 and $803,000 for 2002, relating to
these transactions.
 
    The Company leases its corporate offices and certain centers for periods
generally ranging from three to ten years. These leases include rent escalation
clauses generally tied to the consumer price index and contain provisions for
additional terms at the option of the tenant. The leases generally require the
Company to pay utilities, taxes, insurance and other costs. Rental expense under
such leases was approximately $6,585,000, $2,597,000 and $2,238,000 for the
years ended December 31, 1997, 1996 and 1995, respectively. Ten of the offices
are subleased to affiliated Physicians. By reason of the sublease arrangements,
if the respective Physicians should be unable to pay the rental on the site, the
Company would be contingently liable. As of December 31, 1997, the Company has
subleased the operating sites to the Physicians for the base rental as
stipulated in the original lease. The related sublease income has been offset by
the lease rent expense. The Company also has operating leases for diagnostic
imaging equipment installed in certain of its imaging centers.
 
    The following summary of non-cancelable obligations includes the sublease
arrangements described above, certain equipment leases and the Company's
corporate rentals. As of December 31, 1997, the aggregate future minimum lease
payments and sublease rentals are as follows (in thousands):

    CONTINGENCIES
 
    Between November 1997 and January 1998, several lawsuits were commenced
against the Company, certain of the Company's Directors and certain officers
concerning the related party transactions investigated by the Special Committee
of the Board of Directors ("Special Committee"). The complaints in each action
assert that the Company and the named defendants violated Section 10(b) and
20(a) of the Securities Exchange Act of 1934, alleging that the Company omitted
and/or misrepresented material information in its public filings, including that
the Company failed to disclose that it had entered into acquisitions that were
not in the best interest of the Company, that it had paid unreasonable and
unearned acquisition and financial advisory fees to related parties, and that it
concealed or failed to disclose adverse material information about the Company.
Each action seeks unspecified compensatory damages, with interest, and the costs
and expenses incurred in bringing the action. On February 9, 1998, the above-
mentioned class actions were consolidated for all purposes in federal district
court in New Jersey. On March 31, 1998, the lead plaintiffs in the consolidated
class actions served their Consolidated Class Action Complaint, asserting that
the Company and the named defendants violated Section 10(b) of the Exchange

Act, and that certain named defendants violated Sections 20(a) and 20A of the
Exchange Act. The Company intends to defend vigorously against the allegations.
 
    As previously announced by the Company the U.S. Attorney for the District of
New Jersey commenced an investigation in connection with the disclosures
regarding the related party transactions referred to above. In addition, as
previously disclosed, the Company has also received an inquiry from the SEC, but
no formal proceedings have been commenced by the SEC. The Company has cooperated
fully with these authorities and provided all information requested by them.
 
    On November 7, 1997, the Company accepted the resignations of William D.
Farrell, as President and Chief Operating Officer of the Company and as
Director, and Gary I. Fields, as Senior Vice President and General Counsel. On
the same date, Messrs. Farrell and Fields filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and the
members of the Company's Board of Directors, claiming retaliatory discharge
under the New Jersey Conscientious Employee Protection Act and breach of
contract. On December 17, 1997, the plaintiffs amended their complaint to add a
claim for violation of public policy. The plaintiffs allege that they were
constructively terminated as a result of their objection to certain
related-party transactions, the purported failure of the defendants to
adequately disclose the circumstances surrounding such transactions, and the
Company's public issuance of alleged false and misleading accounts concerning or
relating to such related-party transactions. The plaintiffs seek unspecified
compensatory and punitive damages, interest and costs and reinstatement of the
plaintiffs to their positions with the Company. On April 8, 1998, the Company
filed its Answer to the Amended Complaint, and asserted a counterclaim against
Messrs. Farrell and Fields for breach of fiduciary duties. The Company intends
to defend vigorously against the allegations.
 
    On November 8, 1997, the Company removed John P. O'Malley III, the Company's
Chief Financial Officer, for failure to fulfill certain of his functions as
Chief Financial Officer. Mr. O'Malley has filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and members
of the Board of Directors, as defendants, claiming retaliatory discharge under
the New Jersey Conscientious Employee Protection Act and defamation. Mr.
O'Malley alleges that the Company terminated his employment in retaliation for
voicing the concerns of shareholders and senior management regarding
related-party transactions and because the Company did not want to make full and
adequate disclosure of the facts and circumstances surrounding such
transactions. In addition, Mr. O'Malley alleges that the Company published false
and defamatory statements about him. Mr. O'Malley seeks unspecified compensatory
and punitive damages, interest and costs of bringing the action. On April 8,
1998, the Company filed its Answer to the Complaint, and asserted a counterclaim
against Mr. O'Malley for breach of fiduciary duties. The Company intends to
defend vigorously against the allegations.
 
    The legal proceedings described above are in their preliminary stages.
Although the Company believes it has meritorious defenses to all claims against
it, the Company is unable to predict with any certainty the ultimate outcome of
these proceedings. See discussion of reserves for net costs associated with such
litigation in Note 3.
 
    In 1996, Lavina Orsi and Pompeo Orsi brought an action in the Supreme Court
of the State of New York, King's County against Advanced MRA Imaging Associates
in Brooklyn, New York, a wholly owned subsidiary of the Company ("MRA Imaging"),
for damages aggregating $12,500,000. The plaintiff alleges negligent operations,
improper supervision and hiring practices and the failure to operate the
premises in a safe manner, as a result of which the individual suffered physical
injury. The Company's general liability

and professional negligence insurance carriers have been notified, and it has
been agreed that the general liability insurance will pursue the defense of this
matter, however, such insurers have reserved the right to claim that the scope
of the matter falls outside the Company's coverage. The parties to this matter
are engaged in discovery. The Company believes it has meritorious defenses to
all claims against it and therefore is of the opinion that the Company will not
incur any material settlement cost, net of insurance proceeds (if any).
Accordingly, the Company has made no accrual for any costs associated with such
litigation under SFAS No. 5.
 
    In the normal course of business, the Company is subject to claims and
litigation other than those set forth above. Management believes that such other
litigation will not have a material adverse effect on the Company's financial
position, cash flows or results of operations. Accordingly, the Company has made
no accrual for any costs associated with such litigation under SFAS No. 5.
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration, the Company
granted rights to have such shares registered for resale pursuant to the federal
securities laws. In certain of such acquisitions, the Company has granted
specific remedies to the sellers in the event that the registration statement
covering the relevant shares is not declared effective by the Securities and
Exchange Commission within an agreed-upon period of time, including the right to
require the Company to repurchase the shares issued to such seller. During 1997,
the Company entered into an agreement to fix the repurchase price per common
share related to certain shares covered by a repurchase agreement to the then
current market price in exchange for additional time to obtain registration of
such shares. The increased amount of such repurchase obligation of $1,696,000
(solely related to the fixing of the repurchase price pursuant to the terms of
the original repurchase agreement) was charged to retained earnings and shown as
an increase in Common Stock subject to redemption on the Consolidated Balance
Sheet. As of December 31, 1997, the Company had reflected $9,734,000 of Common
Stock subject to redemption on its Consolidated Balance Sheet related to shares
that the Company may be required to repurchase. During January 1, 1998 through
May 26, 1998, the Company paid $3,275,000 to sellers who exercised their rights
to have 59,667 shares of Common Stock repurchased. In addition, the Company
expects to pay an additional $5,763,000 during the remainder of 1998 in
connection with the settlement of certain repurchase obligations of the Company,
(representing 138,000 shares of Common Stock) subject under certain
circumstances, to the consent of the Senior Notes holders.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay (in additional shares
and/or cash) to the sellers an amount equal to the shortfall in the value of the
issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement (referred
to as "Price Protection"). Any such Price Protection payments will be charged to
stockholders' equity. Based upon the closing sales price of the Company's Common
Stock on May 26, 1998 ($9 3/16 per share), such shortfall would be approximately
$9,634,000, which amount may be reduced by up to $5,977,000 to the extent
certain sellers exercise their repurchase rights referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three

years). The specific terms of such contingent consideration differs for each
acquisition. In connection with certain acquisitions, the Company and the
relevant sellers have agreed to a maximum amount of contingent consideration,
and in other cases, the parties have agreed that any payment of such contingent
consideration may be paid in cash or shares of Common Stock, or a combination of
both. Contingent consideration associated with acquisitions is recorded as
additional purchase price when resolved.
 
12. RELATED PARTY TRANSACTIONS
 
    During 1997, in connection with the placement of the Preferred Stock, the
Company paid $967,000 in fees and expenses to Arnhold & S. Bleichroeder, Inc.,
of which Gary Fuhrman, a director of the Company, is an executive officer and
director. Also during 1997, for legal services rendered to the Company, the
Company paid legal fees in the amount of $971,000 to Werbel & Carnelutti, of
which Stephen Davis, a director of the Company, is a partner. In addition,
during 1997, the Company reimbursed the managing underwriter of the Company's
October public offering $84,000 in charter fees for the use by the managing
underwriter and the Company of an airplane owned by an affiliate of the Chairman
of the Board during the public offering roadshow.
 
    In 1997 and previous years, the Company paid an annual financial advisory
fee to 712 Advisory Services, Inc., a financial advisory firm and affiliate of
the Company's Chairman of the Board (the "Affiliate"). Mr. Neil H. Koffler, a
director of the Company, is also an employee of the Affiliate. Such fees
amounted to $112,500, $102,000 and $225,000 in the years ended December 31,
1997, 1996 and 1995, respectively. During the year ended December 31, 1997, the
Company also paid transaction related advisory fees and expenses (including fees
associated with the issuance of the Senior Notes) to the Affiliate of $1,761,000
and issued to the Affiliate warrants to purchase 225,000 shares of the Company's
Common Stock exercisable at between $30.93 and $37.77 per share for financial
advisory services rendered to the Company in connection with such transactions.
As discussed below, pursuant to recommendations made by the Special Committee,
the Affiliate has reimbursed the Company $1,536,000 of the fees paid to the
Affiliate for services rendered in 1997 and waived $112,500 of fees payable in
1997.
 
    In order to compensate officers, directors, employees and consultants to the
Company for services rendered or to be rendered to the Company, the Company from
time to time has granted options at fair market value to such individuals. As of
December 31, 1997, stock options to purchase 489,555 shares of the Company's
Common Stock have been issued to the Chairman and Mr. Koffler. Included in this
amount are stock options to purchase 250,000 shares and 5,000 shares of the
Company's Common Stock which were granted in May 1997 to the Chairman and Mr.
Koffler, respectively, under the Company's 1997 Stock Option Plan (the "1997
Plan"). The exercise price for the options granted to the Chairman and Mr.
Koffler is $39.38, the fair market value of the Common Stock on the date of
grant. As discussed below, the Chairman and Mr. Koffler agreed in April 1998 to
relinquish the stock options that were granted to them under the 1997 Plan.
 
    In September 1997, the Company acquired, for $3,250,000, a limited
partnership interest in Dune Jet Services, L.P. (the "Partnership"), a Delaware
limited partnership formed for the purposes of acquiring and operating an
airplane for the partner's business uses and for third party charter flights.
The general partner of the Partnership is Dune Jet Services, Inc., a Delaware
corporation, the sole stockholder of which is the Company's Chairman. In October
1997, following discussions among management (members of which expressed
objections to such acquisition), the Special Committee, and other members of the
Board

12. RELATED PARTY TRANSACTIONS (CONTINUED)
of Directors (including the Chairman), the Company's interest in the partnership
was repurchased by the partnership at cost plus interest.
 
    In October 1997, members of the Company's management communicated to the
Board that certain Company stockholders had questioned them regarding the manner
in which related-party transactions are scrutinized by the Company and its
Board. Management stated that it shared the concerns of these stockholders and
had engaged counsel to conduct a review of such transactions.
 
    In order to address and satisfy the concerns management had communicated,
the Company instituted a special investigation to review all related-party
transactions (including those referred to above in this note 12) and the
adequacy of the disclosure of the same. The review also was to seek to develop
recommendations as to what changes, if any, should be made to the Company's
procedures regarding related-party transactions.
 
    The Committee issued the results of its investigation and certain
recommendations in a report to the Company's Board of Directors and on April 6,
1998, the Company's Board of Directors voted to adopt the recommendations
contained in the report. Accordingly, the Committee recommended and the
Affiliate agreed to reimburse the Company approximately $1,424,000 in fees for
transactions completed after June 1, 1997, to reimburse $112,500 of the retainer
paid to the Affiliate for 1997, to waive payment of an additional $112,500 of
fees accrued by the Company for the third and fourth quarters of 1997, and to
pay a substantial amount of the expenses associated with the Committee's
investigations. In addition, the Committee recommended and the Affiliate agreed
to allow the Company to terminate its relationship with the Affiliate.
 
    The Committee responded to the directors that it had determined that: (i)
there was no evidence of any federal or state crimes or securities law
violations in connection with the related party transactions in question; (ii)
all related-party matters were disclosed in public filings; (iii) the Affiliate
performed acquisition advisory services fully consistent with the expectations
and understanding of the committee of outside directors that had approved the
Affiliate's acquisition fees; and (iv) the acquisition advisory fees paid to the
Affiliate in connection with the Company's acquisitions in 1997 were within the
range of customary acquisition advisory fees paid to investment bankers on
transactions of similar size.
 
    The Chairman and Mr. Koffler also agreed voluntarily to relinquish 255,000
stock options that were granted to them in May 1997 and permit the Board's
Compensation Committee, with the assistance of compensation experts, to
determine the appropriate director compensation for 1997. The 255,000 stock
options were granted at prices equal to the then current market price, and
accordingly, no expense was recorded upon issue nor income reflected upon
relinquishment for accounting purposes.
 
    In addition, for the year ended December 31, 1996, the Company paid
transaction related advisory fees and expenses to the Affiliate of $363,000 and
issued to the Affiliate warrants to purchase 40,000 shares of the Company's
common stock exercisable at $27.00 per share for services rendered to the
Company, including services in connection with the NMR acquisition, the public
offering of the Company's common stock in October 1996 and other transactions.

litigation matters regarding related party transactions.

    On February 24, 1995, the Company consummated a merger (the "Merger") with

dated as of February 24, 1995 by and among the Company, Maternity Resources and
the other parties named therein (the "Sellers"). Maternity Resources was formed
on December 27, 1994 for the sole purpose of acquiring Maternity Retail
Partners, L.P. and Kik Kin, L.P. Pursuant to the Agreement, the Company acquired
(i) 100% of the issued and outstanding common stock of Maternity Resources from
the Sellers in exchange for an aggregate of 160,000 shares of the Company's
Common Stock, par value $0.01 and (ii) 100% of the issued and outstanding shares
of Series B and Series C Preferred Stock of Maternity Resources from the holders
thereof in exchange for shares of the Company's Series A Preferred Stock and
Series B Preferred Stock. At the time of the Merger, the Company and Maternity
Resources were under common control through stock ownership and, as a result,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
14. ACQUISITIONS (CONTINUED)
the Merger was accounted for as a transfer between entities under common
control. Under this method of accounting, when entities are under common
control, the assets, liabilities and operations are combined at historical cost
in a manner similar to that in pooling of interests accounting. In November
1995, the Company sold its Maternity Resources subsidiaries and consequently
transferred all of Maternity Resources liabilities to unaffiliated third
parties. The Company has no material contingent liabilities remaining with
respect to Maternity Resources. Since the Maternity operations have been sold,
Maternity Resources has been reported as a discontinued operation.
 
    Maternity apparel revenues were recognized on an accrual basis as earned and
realizable and consisted of net revenue derived from the wholesale and retail
sale of maternity clothing and apparel. Maternity apparel revenues amounted to
approximately $11,057,000 for the year ended December 31, 1995. The initial
purchase price of $4,076,000 (the aggregate recorded fair value of the Common
Stock and the Preferred Stock issued by the Company in connection with the
Merger) exceeded the book value of net assets acquired of $1,120,000 by
$2,955,000. This amount could be considered a distribution to shareholders. On
December 27, 1995, preferred shares, which were included as part of the
$4,076,000 having a potential redemption value of $2,392,000 were redeemed by
the Company for an agreed upon aggregate amount of $24,000. The net amount paid
in excess of the net assets acquired after the redemption amounted to $564,000.
The acquisition of Maternity was accounted for in a manner similar to that in a
pooling of interests. This accounting resulted in certain adjustments directly
to stockholders' equity. A credit of $1,022,000 was made to paid-in-capital
related to the forgiveness of certain debt owed by Maternity to affiliated
organizations that is accounted for as a capital contribution due to the related
party nature. A credit of $570,000 was made to retained deficit that represents
a portion of Maternity's January 1995 losses attributable to a subsidiary. These
losses were included in the Company's 1994 operations in recognition of the then
full year's operating results for the specific subsidiary's year ended January
31, 1995. Accordingly, the amount duplicated in 1995 operating results is
reversed. A charge of $269,000 to paid-in-capital relates to a cash redemption
by Maternity of its then outstanding redeemable preferred stock prior to the
merger. Maternity Retail Partners L.P. has also been included in the Company's
consolidated operating results for the twelve months ended December 31, 1995.
 
    On May 26, 1995, the Company consummated the acquisition of the business
operations of New England MRI, Inc. ("New England MRI"), a Florida corporation

centers (the "Centers"). The acquisition was consummated pursuant to an Asset
Purchase Agreement (the "Agreement") dated as of May 17, 1995 by and among two
of the Company's wholly owned subsidiaries--Fort Myers Resources, Inc. ("FMR")
and Central Fort Myers Resources, Inc. ("CFMR"), and "New England MRI". Pursuant
to the Agreement, FMR acquired substantially all of the assets of one of the
centers and CFMR acquired all of the assets of the other center through the
issuance of 400,000 shares of the Company's Common Stock valued at $3,449,000.
Of the 400,000 shares, 200,000 shares were issued at closing with the remaining
200,000 shares to be issued within two years of closing (200,000 of such shares
were issued in 1997). The centers achieved certain earnings objectives and as a
result, an additional 66,667 shares were issued in September 1997, to New
England MRI, in accordance with the additional consideration provisions in the
purchase agreement. The market value of the shares upon issuance was recorded as
additional goodwill subject to amortization over the stated period. The excess
of the purchase price over the fair value of net assets acquired amounted to
approximately $5,746,000 and is being amortized on a straight line basis over 20
years. The accompanying Consolidated Financial Statements include the operations
of FMR and CFMR from the above date of

purchased assets are subject to certain registration rights.
 
    On June 19, 1995, the Company consummated the acquisition of the business
operations of PCC Imaging, Inc. ("PCC"), which owns and manages a diagnostic
imaging center. The acquisition was consummated pursuant to an Asset Purchase
Agreement (the "Agreement") dated June 19, 1995 by and among the Company's
wholly owned subsidiary, Hackensack Resources, Inc. ("HRI") and PCC. Pursuant to
the agreement, HRI acquired substantially all of the assets of the center for
$1,800,000 in cash. The acquisition was accounted for as a purchase, under which
the purchase price was allocated to the acquired assets and assumed liabilities
based upon fair values at the date of acquisition. The excess of the purchase
price over the fair value of net assets acquired amounted to $751,000 and is
being amortized on a straight line basis over 20 years. The accompanying
consolidated financial statements include the operations of PCC from the above
date of acquisition.
 
    The following table summarizes the unaudited pro forma results of continuing
operations for the years ended December 31, 1997 and 1996, assuming the 1997
imaging center acquisitions had occurred on January 1, 1997 and 1996 and the

goodwill and other long-lived assets and other unusual charges of $9,723,000.
See Note 3 of the Notes to the Consolidated Financial Statements for further
details. The fourth quarter of 1997 also includes additional charges related to
increases in the estimated provision for uncollectible accounts receivable and
higher contractual allowance estimates.
 
    Quarterly results are generally affected by the timing of acquisitions.
 
16. SUBSEQUENT EVENTS
 
AGREEMENT IN PRINCIPLE REGARDING SENIOR NOTE DEFAULTS
 
    Management has reached an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications. Under the terms of the agreement in principle, the Senior Note
lenders have agreed to waive all existing covenant defaults and to modify the
financial covenants applicable over the remaining term of the Senior Notes. In
consideration for these waivers and covenant modifications, the Company has
agreed to increase the effective blended interest rate on the Senior Notes from
7.87% to 9.00%, and issue to the Senior Note lenders warrants to acquire 375,000
shares of the Company's Common Stock at an exercise price of $7.67 per common
share. In

16. SUBSEQUENT EVENTS (CONTINUED)
addition, the Company has agreed to prepay $2,000,000 of principal outstanding
on the Senior Notes (without premium) and to pay a fee to the Senior Note
lenders of $500,000. The agreement in principle is subject to the execution of
definitive documents, which are expected to be completed during September 1998.
There can be no assurance, however, that definitive documents effecting the
agreement in principle will be executed.
 
    Upon execution of the definitive documents with respect to the Senior Notes,
the Senior Notes and the Cross Default Debt will no longer be in default and
will be shown as long-term debt in future financial statements of the Company.
 
SALE OF STARMED
 
    Through the Per Diem and Travel Nursing Divisions of its wholly-owned
subsidiaries, StarMed Staffing, Inc. and Wesley Medical Resources Inc.
("StarMed"), the Company provides temporary healthcare staffing of registered
nurses and other medical personnel to acute and sub-acute care facilities
nationwide. On August 18, 1998, the Company sold the stock of StarMed to
RehabCare Group, Inc. for gross proceeds of $33,000,000 (the "StarMed Sale").
Due to the StarMed Sale, the amounts in the accompanying Consolidated Statements
of Operations and related notes thereto have been restated to reflect StarMed as
a discontinued operation.
 
    Net cash proceeds from the StarMed Sale were used as follows: (i)
$13,786,000 to repay StarMed's outstanding third-party debt (in accordance with
the terms of sale) (ii) $2,000,000 was placed in escrow to be available, for a
specified period of time, to fund indemnification obligations that may be
incurred by the Company (part or all of this amount may be payable to the
Company over time) and (iii) an additional $2,000,000 was placed into escrow to
be applied as a partial repayment of the Company's $78,000,000 of Senior Notes.
The remaining net proceeds of approximately $13,400,000 increased the Company's
consolidated cash balances. For accounting purposes, a pretax gain from the
StarMed Sale of approximately $5,000,000 is expected to be reported in the third
quarter of 1998.

16. SUBSEQUENT EVENTS (CONTINUED)
    See note 14 for discontinued operations relating to Maternity Resources,
Inc. for 1995.
 
    In June 1998, an individual filed a complaint against the Company, StarMed,
Wesley Medical Resources, Inc., a subsidiary of the Company ("Wesley"), and
certain officers and directors of the Company in the United States District
Court for the Northern District of California. The complaint, among other
things, alleges that the defendants omitted and/or misrepresented material
information in the Company's public filings and that they concealed or failed to
disclose adverse material information about the Company in connection with the
sale of Wesley to the Company by the plaintiff. The plaintiff seeks damages in
the amount of $4.25 million or, alternatively, recession of the sale of Wesley.
The Company believes that it has meritorious defenses to the claims asserted by
plaintiff, and intends to defend itself vigorously. In July 1998, the Company
and the named defendants filed a motion to dismiss the plaintiff's complaint on
numerous grounds. The legal proceeding described above is in its preliminary
stages. Although the Company believes it has meritorious defenses to all claims
against it, the Company is unable to predict with any certainty the ultimate
outcome of such proceeding.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
 
1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES
 
    GENERAL
 
    The accompanying unaudited consolidated financial statements of Medical
Resources, Inc. (the "Company") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete consolidated financial statements. In the
opinion of management, all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation have been included.
Operating results for the interim periods are not necessarily indicative of the
results that may be expected for an entire year.
 
    The unaudited consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
contained herein for the year ended December 31, 1997.
 
    During July 1998, the Company's shareholders approved a reverse stock split
of the Company's outstanding shares of Common Stock. As a result of the reverse
stock split, each three outstanding shares of Common Stock were automatically
converted into one share of new Common Stock. The Company effected the reverse
stock split in order to meet the minimum bid price requirement for continued
listing on the Nasdaq Stock Market. The share data included herein have been
adjusted to reflect the impact of the reverse stock split.
 
    THE COMPANY
 
    The Company operates and manages primarily fixed-site, free-standing
outpatient medical diagnostic imaging centers (herein referred to as "centers"),
and provides diagnostic imaging network management services to managed care
providers. The Company, through its wholly-owned subsidiary, Dalcon
Technologies, Inc., also develops and markets software products and systems for
the diagnostic imaging industry.
 
    Until August 1998, the Company, through the Per Diem and Travel Nursing
divisions of its wholly-owned subsidiaries, StarMed Staffing, Inc. and Wesley
Medical Resources Inc. ("StarMed"), provided temporary healthcare staffing of
registered nurses and other medical personnel to acute and sub-acute care
facilities nationwide. On August 18, 1998, the Company sold the stock of StarMed
to RehabCare Group, Inc. for gross proceeds of $33,000,000 (the "StarMed Sale").
Due to the StarMed Sale, the results of operations of StarMed are herein
reflected in the Company's Consolidated Statements of Operations as discontinued
operations (see Note 6).
 
    REVENUE RECOGNITION
 
    At each of the Company's diagnostic imaging centers, all medical services
are performed exclusively by physician groups (the "Physician Group" or the
"Interpreting Physician"), generally consisting of radiologists with whom the
Company has entered into independent contractor agreements. Pursuant to these
agreements, the Company has agreed to provide equipment, premises, comprehensive
management and administration, including responsibility for billing and
collection of receivables, and technical imaging services to the Interpreting
Physician.
 
    Net service revenues are reported, when earned, at their estimated net
realizable amounts from patients, third party payors and others for services
rendered at contractually established billing rates which

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
 
1. DESCRIPTION OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
generally are at a discount from gross billing rates. Known and estimated
differences between contractually established billing rates and gross billing
rates ("contractual allowances") are recognized in the determination of net
service revenues at the time services are rendered. Subject to the foregoing,
the Company's imaging centers recognize revenue under one of the three following
types of agreements with Interpreting Physicians:
 
        TYPE I--The Company receives a technical fee for each diagnostic imaging
    procedure performed at a center, the amount of which is dependent upon the
    type of procedure performed. The fee included in revenues is net of
    contractual allowances. The Company and the Interpreting Physician
    proportionally share in any losses due to uncollectible amounts from
    patients and third party payors, and the Company has established reserves
    for its share of the estimated uncollectible amount.
 
        TYPE II--The Company bills patients and third party payors directly for
    services provided and pays the Interpreting Physicians either (i) a fixed
    percentage of fees collected at the center, or (ii) a contractually fixed
    amount based upon the specific diagnostic imaging procedures performed.
    Revenues are recorded net of contractual allowances and the Company accrues
    the Interpreting Physician fee as an expense on the Consolidated Statements
    of Operations. The Company bears the risk of loss due to uncollectible
    amounts from patients and third party payors, and the Company has
    established reserves for the estimated uncollectible amount.
 
        TYPE III--The Company receives from an affiliated physician association
    a fee for the use of the premises, a fee per procedure for acting as billing
    and collection agent and a fee for administrative and technical service
    performed at the centers. The affiliated physician association contracts
    with and pays directly the Interpreting Physicians. The Company's fee, net
    of an allowance based upon the affiliated physician association's ability to
    pay after the association has fulfilled its obligations (i.e., estimated
    future net collections from patients and third party payors less facility
    lease expense and Interpreting Physicians fees), constitutes the Company's
    net service revenues. Since the Company's net service revenues are dependent
    upon the amount ultimately realized from patient and third party
    receivables, the Company's revenue and receivables have been reduced by an
    estimate of patient and third party payor contractual allowances, as well as
    an estimated provision for uncollectible amounts from patients and third
    party payors.
 
    Revenues derived from Medicare and Medicaid are subject to audit by such
agencies. The Company is not aware of any pending audits.
 
    The Company also recognizes revenue from the sale of radiology information
systems. Such revenues are recognized on an accrual basis as earned.
 
    RECLASSIFICATION AND RESTATEMENT
 
    The Consolidated Statement of Operations for the three month and six month
periods ended June 30, 1997 have been restated to include a non-cash charge of
$2,305,000 for compensation expense resulting from stock options granted in 1996
and early 1997 that were approved by the Company's stockholders in May 1997. In
addition, certain prior year amounts have been reclassified to conform to the
current year presentation.

    COMPREHENSIVE INCOME
 
    Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130").
SFAS No. 130 requires an entity to report comprehensive income and its
components and increases financial reporting disclosures. This standard has no
impact of the Company's financial position, cash flows or results of operations
since the Company's comprehensive income is the same as its reported net income.
 
EARNINGS PER SHARE
 
    Effective for the year ended December 31, 1997, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share." This statement requires the presentation of Basic Earnings per Share and
Diluted Earnings per Share. Basic earnings per share is based on the weighted
average number of common shares outstanding during the period. Diluted earnings
per share is based on the weighted average number of common shares outstanding
during the period plus the potentially issuable common shares related to
outstanding stock options, warrants and convertible debt. Earnings per share
amounts for the three and six months ended June 30, 1997 have been restated to
conform to the requirements of SFAS No. 128.

2. BASIS OF FINANCIAL STATEMENT PRESENTATION AND ISSUES AFFECTING LIQUIDITY
 
    As a result of its net loss for 1997 and the late filing of its 1997 Annual
Report on Form 10-K, the Company is currently in default of certain financial
covenants under the agreements for its $78,000,000 of Senior Notes. The
financial covenant defaults under the Senior note agreements entitle the lenders
to exercise certain remedies including acceleration of repayment. In addition,
certain medical equipment notes, and operating and capital leases of the

Default Debt"), contain provisions which allow the creditors or lessors to
accelerate their debt or terminate their leases and seek certain other remedies
if the Company is in default under the terms of agreements such as the Senior
Notes. In the event that the Senior Note lenders or the holders of the Cross
Default Debt elect to exercise their right to accelerate the obligations under
the Senior Notes or the other loans and leases, such acceleration would have a
material adverse effect on the Company, its operations and its financial
condition. Furthermore, if such obligations were to be accelerated, in whole or
in part, there can be no assurance that the Company would be successful in
identifying or consummating financing necessary to satisfy the obligations which
would become immediately due and payable. As a result of the uncertainty related
to the defaults and corresponding remedies described above, the Senior Notes and
the Cross Default Debt were shown as current liabilities on the Company's
Consolidated Balance Sheets at June 30, 1998 and December 31, 1997. Accordingly,
the Company had a deficit in working capital of $55,892,000 at June 30, 1998.
These matters raise substantial doubt about the Company's ability to continue as
a going concern. The report of the Company's independent auditors, Ernst & Young
LLP, on the consolidated financial statements of the Company for the year ended
December 31, 1997 contains an explanatory paragraph with respect to the issues
that raise substantial doubt about the Company's ability to continue as a going
concern mentioned in Note 2 to the Company's consolidated financial statements.
The financial statements do not include any further adjustments reflecting the
possible future effects on the recoverability and classification of assets or
the amount and classification of liabilities that may have resulted from the
outcome of this uncertainty.
 
    Management has reached an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications. Under the terms of the agreement in principle, the Senior Note
lenders have agreed to waive all existing covenant defaults and to modify the
financial covenants applicable over the remaining term of the Senior Notes. In
consideration for these waivers and covenant modifications, the Company has
agreed to increase the effective blended interest rate on the Senior Notes from
7.87% to 9.00%, and issue to the Senior Note lenders warrants to acquire 375,000
shares of the Company's Common Stock at an exercise price of $7.67 per common
share. In addition, the Company has agreed to prepay $2,000,000 of principal
outstanding on the Senior Notes (without premium) and to pay a fee to the Senior
Note lenders of $500,000. The agreement in principle is subject to the execution
of definitive documents, which are expected to be completed during September
1998. There can be no assurance, however, that definitive documents effecting
the agreement in principle will be executed.
 
    In addition to reaching an agreement in principle with the Senior Note
lenders with respect to existing covenant defaults and certain covenant
modifications, the Company has taken various actions in response to this
situation, including the following: (i) it effected a workforce reduction in
March 1998 aimed at reducing the Company's overall expense levels by
approximately $5,000,000 per annum and (ii) sold the Company's temporary
healthcare staffing business, StarMed, for $33,000,000 in August 1998. Upon
execution of the definitive documents with respect to the Senior Notes, the
Senior Notes and the Cross Default Debt will no longer be in default and will be
shown as long-term debt in future financial statements of the Company.
 
3. UNUSUAL CHARGES
 
    During the three months ended June 30, 1998, the Company recorded $1,640,000
of unusual charges consisting of (i) $1,240,000 for penalties associated with
delays in the registration of the Company's

Common Stock issuable upon conversion of convertible preferred stock and (ii)
$400,000 for defense costs relating to shareholder and employee lawsuits.
 
    During the six months ended June 30, 1998, the Company recorded $5,400,000
of unusual charges consisting of (i) $3,467,000 ($1,194,000 of which was a
non-cash charge related to the issuance of 117,000 common stock warrants) for
penalties associated with delays in the registration of the Company's Common
Stock issued in connection with acquisitions or issuable upon conversion of
convertible preferred stock, (ii) $713,000 for defense costs relating to
shareholder and employee lawsuits, (iii) $883,000 for costs associated with the
investigation of related party transactions which was concluded in April 1998
and (iv) $337,000 for management termination benefits and related costs.
 
    The Company could incur a substantial additional amount of unusual charges
during the remainder of 1998 depending upon the outcome of current negotiations
regarding penalties associated with the failure to register the Company's Common
Stock and waivers or amendments of the financial covenants under its Senior
Notes, and the outcome of certain litigation.

    Accounts receivable is net of contractual allowances, which represent
standard fee reductions negotiated with certain third party payors. Contractual
allowances amounted to approximately $30,415,000 and $20,094,000 for the three
months ended June 30, 1998 and 1997, respectively, and approximately $59,265,000
and $31,093,000 for the six months ended June 30, 1998 and 1997, respectively.
 
5. COMMITMENTS AND CONTINGENCIES
 
    Between November 1997 and January 1998, several lawsuits were commenced
against the Company, certain of the Company's Directors and certain officers
concerning certain related party transactions that have since been investigated
by a Special Committee of the Board of Directors ("Special Committee"). The
complaints in each action assert that the Company and the named defendants
violated Section 10(b) and 20(a) of the Securities Exchange Act of 1934,
alleging that the Company omitted and/or misrepresented material information in
its public filings, including that the Company failed to disclose that it had

5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
entered into acquisitions that were not in the best interest of the Company,
that it had paid unreasonable and unearned acquisition and financial advisory
fees to related parties, and that it concealed or failed to disclose adverse
material information about the Company. Each action seeks unspecified
compensatory damages, with interest, and the costs and expenses incurred in
bringing the action. On February 9, 1998, the above-mentioned class actions were
consolidated for all purposes in federal district court in New Jersey. On March
31, 1998, the lead plaintiffs in the consolidated class actions served their
Consolidated Class Action Complaint, asserting that the Company and the named
defendants violated Section 10(b) of the Exchange Act, and that certain named
defendants violated Sections 20(a) and 20A of the Exchange Act. The Company
intends to defend vigorously against the allegations.
 
    The Special Committee issued the results of its investigation and certain
recommendations in a report to the Company's Board of Directors and on April 6,
1998, the Company's Board of Directors voted to adopt the recommendations
contained in the report. Accordingly, the Special Committee recommended and 712
Advisory Services, Inc., a financial advisory firm and affiliate of the
Company's Chairman of the Board (the "Affiliate), agreed to reimburse the
Company approximately $1,424,000 in fees for transactions completed after June
1, 1997, to reimburse $112,500 of the retainer paid to the Affiliate for 1997,
to waive payment of an additional $112,500 of fees accrued by the Company for
the third and fourth quarters of 1997, and to pay a substantial amount of the
expenses associated with the Special Committee's investigations. All such
amounts have been paid or reimbursed to the Company. In addition, the Special
Committee recommended and the Affiliate agreed to allow the Company to terminate
its relationship with the Affiliate.
 
    The Special Committee reported to the directors that it had determined that:
(i) there was no evidence of any federal or state crimes or securities law
violations in connection with the related party transactions in question; (ii)
all related-party matters were disclosed in public filings; (iii) the Affiliate
performed acquisition advisory services fully consistent with the expectations
and understanding of the committee of outside directors that had approved the
Affiliate's acquisition fees; and (iv) the acquisition advisory fees paid to the
Affiliate in connection with the Company's acquisitions in 1997 were within the
range of customary acquisition advisory fees paid to investment bankers on
transactions of similar size.
 
    As previously announced by the Company, the U.S. Attorney for the District
of New Jersey commenced an investigation in connection with the disclosures
regarding the related party transactions referred to above. In addition, the
Company has also received an inquiry from the SEC, but there have been no formal
proceedings commenced by the SEC. The Company has cooperated fully with these
authorities and provided all information requested by them.
 
    On November 7, 1997, the Company accepted the resignations of William D.
Farrell, as President and Chief Operating Officer of the Company and as
Director, and Gary I. Fields, as Senior Vice President and General Counsel. On
the same date, Messrs. Farrell and Fields filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and the
members of the Company's Board of Directors, claiming retaliatory discharge
under the New Jersey Conscientious Employee Protection Act and breach of
contract. On December 17, 1997, the plaintiffs amended their complaint to add a
claim for violation of public policy. The plaintiffs allege that they were
constructively terminated as a result of their objection to certain
related-party transactions, the purported failure of the defendants to
adequately disclose the circumstances surrounding such transactions, and the
Company's public issuance of alleged false and misleading accounts concerning or
relating to such related-party transactions. The plaintiffs seek unspecified
compensatory and punitive damages, interest and costs and reinstatement of the
plaintiffs to

their positions with the Company. On April 8, 1998, the Company filed its Answer
to the Amended Complaint, and asserted a counterclaim against Messrs. Farrell
and Fields for breach of fiduciary duties. The Company intends to defend
vigorously against the allegations.
 
    On November 8, 1997, the Company removed John P. O'Malley III, the Company's
Chief Financial Officer, for failure to fulfill certain of his functions as
Chief Financial Officer. Mr. O'Malley has filed a complaint in the Superior
Court of New Jersey, Law Division, Essex County, against the Company and members
of the Board of Directors, as defendants, claiming retaliatory discharge under
the New Jersey Conscientious Employee Protection Act and defamation. Mr.
O'Malley alleges that the Company terminated his employment in retaliation for
voicing the concerns of shareholders and senior management regarding
related-party transactions and because the Company did not want to make full and
adequate disclosure of the facts and circumstances surrounding such
transactions. In addition, Mr. O'Malley alleges that the Company published false
and defamatory statements about him. Mr. O'Malley seeks unspecified compensatory
and punitive damages, interest and costs of bringing the action. On April 8,
1998, the Company filed its Answer to the Complaint, and asserted a counterclaim
against Mr. O'Malley for breach of fiduciary duties. The Company intends to
defend vigorously against the allegations.
 
    The legal proceedings described above are in their preliminary stages.
Although the Company believes it has meritorious defenses to all claims against
it, the Company is unable to predict with any certainty the ultimate outcome of
these proceedings.
 
    In 1996, Lavina Orsi and Pompeo Orsi brought an action in the Supreme Court
of the State of New York, King's County against Advanced MRA Imaging Associates
in Brooklyn, New York, a wholly owned subsidiary of the Company ("MRA Imaging"),
for damages aggregating $12,500,000. The plaintiff alleges negligent operations,
improper supervision and hiring practices and the failure to operate the
premises in a safe manner, as a result of which the individual suffered physical
injury. The Company's general liability and professional negligence insurance
carriers have been notified, and it has been agreed that the general liability
insurance will pursue the defense of this matter, however, such insurers have
reserved the right to claim that the scope of the matter falls outside the
Company's coverage. The parties to this matter are engaged in discovery. The
Company believes it has meritorious defenses to all claims against it and
therefore is of the opinion that the Company will not incur any material
settlement cost, net of insurance proceeds (if any). Accordingly, the Company
has made no accrual for any costs associated with such litigation under SFAS No.
5.
 
    In the normal course of business, the Company is subject to claims and
litigation other than those set forth above. Management believes that such other
litigation will not have a material adverse effect on the Company's financial
position, cash flows or results of operations. Accordingly, the Company has made
no accrual for any costs associated with such litigation under SFAS No. 5.
 
    In connection with certain of the Company's 1997 acquisitions in which the
Company issued shares of its Common Stock as partial consideration, the Company
granted rights to have such shares registered for resale pursuant to the federal
securities laws. In certain of such acquisitions, the Company has granted
specific remedies to the sellers in the event that the registration statement
covering the relevant shares is not declared effective by the Securities and
Exchange Commission within an agreed-upon period of time, including the right to
require the Company to repurchase the shares issued to such seller. During 1997,
the Company entered into an agreement to set the purchase price per common share
related to certain shares covered a repurchase agreement to the then current
market price in exchange for additional time to obtain

5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
registration of such shares. The increased amount of such repurchase obligation
of $1,696,000 was charged to retained earnings and shown as an increase in
Common Stock subject to redemption on the Consolidated Balance Sheet. As of June
30, 1998 and December 31, 1997, the Company had reflected $5,509,000 and
$9,734,000, respectively, of Common Stock subject to redemption on its
Consolidated Balance Sheet related to shares that the Company may be required to
repurchase. During the first six months, ended June 30, 1998, the Company paid
$3,311,000 to sellers who exercised their rights to have shares of Common Stock
repurchased. The Company expects to pay an additional $5,509,000 during the
remainder of 1998 ($3,696,000 of which was due and payable on June 3, 1998 (the
"June 1998 Repurchase Obligation") but has not been paid by the Company) in
connection with the settlement of certain repurchase obligations of the Company
subject, under certain circumstances, to the consent of the Senior Note holders.
With respect to the June 1998 Repurchase Obligation which remains due and
payable, the Company is in discussions with the sellers to whom such obligations
are owed and the Senior Note lenders regarding the timing and satisfaction of
the June 1998 Repurchase Obligation.
 
    In addition, in connection with certain of such acquisitions, the Company
has agreed with the sellers in such acquisitions to pay to the sellers (in
additional shares and/or cash) an amount equal to the shortfall in the value of
the issued shares in the event the market value of such shares at the relevant
effective date of the registration statement or other negotiated date is less
than the market value of such shares as of the closing of the acquisition or, in
other cases, as of the execution of the relevant acquisition agreement (referred
to as "Price Protection"). Any such Price Protection payments will be charged to
stockholders' equity. Based upon the closing sales price of the Company's Common
Stock on September 1, 1998 ($4.00 per share), such shortfall would be
approximately $3,351,000, excluding Price Protection obligations related to the
shares which have repurchase obligations, referred to above.
 
    In addition, in connection with certain of the Company's acquisitions, the
Company has agreed with the relevant sellers that all or a portion of the
consideration for such acquisitions will be paid on a contingent basis based
upon the profitability, revenues or other financial criteria of the acquired
business during an agreed-upon measurement period following the closing of the
acquisition (usually, one to three years). The specific terms of such contingent
consideration differ for each acquisition. In connection with certain
acquisitions, the Company and the relevant sellers have agreed to a maximum
amount of contingent consideration and in other cases the parties have agreed
that any payment of such contingent consideration may be paid in cash or shares
of Common Stock, or a combination of both.
 
    Although the Company has the option, in certain cases, to pay certain of
such amounts in shares of Common Stock, payment of significant cash funds to
sellers in the event such remedies or earnout provisions are triggered could
have a material adverse effect on the Company's cash flow and financial
condition. In addition, the Company may be required to finance all or a portion
of any such cash payments from third-party sources. No assurance can be given
that such capital will be available on terms acceptable to the Company. In
addition, the issuance by the Company of shares of Common Stock in payment of
any such owed amounts could be dilutive to the Company's stockholders.
Contingent consideration associated with acquisitions is recorded as additional
purchase price when resolved.
 
    Pursuant to the terms of the Series C Convertible Preferred Stock Purchase
Agreement, dated July 21, 1997, and the Registration Rights Agreement dated July
21, 1997, as amended, between the Company and RGC International, LDC ("RGC")
(hereinafter referred to as the "RGC Agreements"), the Company issued 18,000
shares of Series C Convertible Preferred Stock, $1,000 stated value per share
(the "Series C Preferred Stock") to RGC. Under the RGC Agreements, the Company
was required to use its best efforts

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
 
5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
to include the shares of Common Stock issuable upon conversion of the Series C
Preferred Stock (the "RGC Conversion Shares") in an effective Registration
Statement on Form S-3 not later than October 1997. As amended, the RGC
Agreements provide for monthly penalties ("RGC Registration Penalties") in the
event that the Company failed to register the Conversion Shares prior to October
1997 with such penalties continuing until July 23, 1998.
 
    On June 18, 1998 2,500 shares of Series C Preferred Stock were converted
into 373,000 shares of Common Stock. Accordingly, as of June 30, 1998, 15,500
shares of the Company's Series C Preferred Stock were issued and outstanding.
Each share of the Series C Preferred Stock is convertible into such number of
shares of Common Stock as is determined by dividing the stated value ($1,000) of
each share of Series C Preferred Stock plus 3% per annum from the closing date
to the conversion date by the lesser of (i) $62.10 or (ii) the average of the
daily closing bid prices for the Common Stock for the (5) five consecutive
trading days ending five (5) trading days prior to the date of conversion.
 
    As a result of the Company's continued failure to register the RGC
Conversion Shares, the Company: (i) issued warrants to RGC to acquire 389,000
shares of Common Stock at an exercise prices ranging from $34.86 to $38.85 per
share, subject to reset in November 1998 (such warrants having an estimated
value, for accounting purposes, of $3,245,000); and (ii) issued interest bearing
promissory notes (the "RGC Penalty Notes") in the aggregate principal amount of
$2,450,000 due the earlier of (x) January 4, 1999 and (y) the later of (A) five
business days following the sale of StarMed and (B) October 15, 1998 in the
event the sale of StarMed occurs before October 15, 1998. The principal amount
of and interest accrued on the RGC Penalty Notes may be converted, at the option
of the Company or RGC in certain circumstances, into additional shares of Series
C Preferred Stock or Common Stock. Pursuant to an amendment to the RGC
Agreements entered into June 1998, the Company will no longer incur any monthly
penalties for failure to register the RGC Conversion Shares following July 23,
1998. However, if the RGC Conversion Shares are not registered as of September
15, 1998 (the Company is currently in discussions with RGC to extend such date),
RGC may demand a one-time penalty of $1,550,000 (the "September 1998 Penalty"),
payable, at the option of RGC, in cash or additional shares of Common Stock.
There can be no assurance that the Company will be able to register the RGC
Conversion Shares by such date, or any extended date, or that the Company will
be able to pay the RGC Penalty Notes when due or the September 1998 Penalty, if
such payment becomes due. Purchasers of Common Stock could therefore experience
substantial dilution upon conversion of the Series C Preferred Stock and the RGC
Penalty Notes and the exercise of such warrants. The shares of Series C
Preferred Stock are not registered and may be sold only if registered under the
Act or sold in accordance with an applicable exemption from registration, such
as Rule 144.
 
6. DISCONTINUED OPERATIONS
 
    On August 18, 1998, the Company sold the stock of StarMed to RehabCare
Group, Inc. for gross proceeds of $33,000,000 (the "StarMed Sale"). Due to the
StarMed Sale, the results of operations of StarMed are herein reflected in the
Company's Consolidated Statements of Operations as discontinued operations.
 
    Net cash proceeds from the StarMed Sale were used as follows: (i)
$13,786,000 to repay StarMed's outstanding third-party debt (in accordance with
the terms of sale) (ii) $2,000,000 was placed in escrow to be available, for a
specified period of time, to fund indemnification obligations that may be
incurred by the Company (part or all of this amount may be payable to the
Company over time) and (iii) an additional $2,000,000 was placed into escrow to
be applied as a partial repayment of the Company's $78,000,000 of

the third quarter of 1998.

    In June 1998, an individual filed a complaint against the Company, StarMed,
Wesley Medical Resources, Inc., a subsidiary of the Company ("Wesley"), and
certain officers and directors of the Company in the United States District
Court for the Northern District of California. The complaint, among other
things, alleges that the defendants omitted and/or misrepresented material
information in the Company's public filings and that they concealed or failed to
disclose material adverse information about the Company in connection with the
sale of Wesley to the Company by the plaintiff. The plaintiff seeks damages in
the amount of $4.25 million or, alternatively, recission of the sale of Wesley.
The Company believes that it has meritorious defenses to the claims asserted by
plaintiff, and intends to defend itself vigorously. In July 1998, the Company
and the named defendants filed a motion to dismiss the plaintiff's complaint on
numerous grounds. The legal proceeding described above is in its preliminary
stages. Although the Company believes it has meritorious defenses to all claims
against it, the Company is unable to predict with any certainty the ultimate
outcome of such proceeding.
 
7. SUBSEQUENT EVENT
 
    In July 1998, the Company decided to sell or close approximately eight
imaging centers. These centers will be sold or closed during the third and
fourth quarters of 1998. In most cases, the Company decided to sell or close
these centers due to general competitive pressures and their close proximity to
other imaging centers of the Company which have more advanced imaging equipment.
The Company expects to incur a charge of between $3,000,000 and $4,000,000
during the third quarter of 1998 related to these imaging centers. Such charge
will consist of (i) the write-off of fixed assets and other assets of between
$2,000,000 and $2,600,000 and (ii) reserve for costs to exit facility and
equipment leases of between $1,000,000 and $1,400,000.
