         THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
         AS AMENDED. NO SALE OR DISPOSITION OF THIS WARRANT MAY BE MADE WITHOUT
         AN EFFECTIVE REGISTRATION STATEMENT RELATING THERETO OR AN EXEMPTION
         THEREUNDER SUCH THAT REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES
         ACT OF 1933.

                              U.S. DIAGNOSTIC INC.

                              AMENDED AND RESTATED

                          COMMON STOCK PURCHASE WARRANT

          THIS AMENDED AND RESTATED WARRANT to purchase shares of common stock,
$.01 par value, (the "COMMON STOCK") of U.S. DIAGNOSTIC INC., a Delaware
corporation (the "COMPANY") evidences that, for valuable consideration, receipt
of which is hereby acknowledged, DVI FINANCIAL SERVICES INC., a Delaware
corporation ("PURCHASER"), or registered assigns, is entitled to subscribe for
and purchase from the Company, an aggregate of up to Two Hundred Fifty Thousand
(250,000) shares (subject to adjustment as specified in SECTION 4 hereof) of the
fully paid and nonassessable, Common Stock, (the "WARRANT STOCK"), at the price
per share equal to the closing price per share paid for Common Stock of the
Company on December 23, 1998, on the principal national securities exchange on
which the Common Stock is admitted to trading (such price and such other price
as results, from time to time from the adjustments specified in SECTION 4
hereof, is referred to herein as the "EXERCISE PRICE"), subject to the
provisions and upon the terms and conditions set forth herein.

         1. CONDITIONS TO EXERCISE. The purchase right represented by this
Warrant is exercisable, in whole or in part, as to the Warrant Stock at any time
after April 30, 1998, and from time to time, on or before September 30, 2005.
This Warrant expires and may not be exercised after September 30, 2005.

          2. METHOD OF EXERCISE: PAYMENT. ISSUANCE OF NEW WARRANT. The purchase
right represented by this Warrant may be exercised at any time, and from time to
time, by the surrender of this Warrant (with the Notice of Exercise form
attached hereto duly executed) at the principal office of the Company and by the
payment to the Company by check in an amount equal to the then applicable
Exercise Price per share multiplied by the number of shares of the Warrant Stock
then being purchased. In the event of any exercise of the rights represented by
this Warrant, the Company shall deliver to Purchaser certificates for the shares
of the Warrant Stock so purchased within a reasonable time, but not later than
twenty business days after exercise. This Warrant will be deemed to have been
exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above and the person entitled to receive the
shares of the Warrant Stock issuable upon such exercise is treated for all
purposes as 



                                       1
<PAGE>   2

the holder of such shares of record as of the close of business on such date.
Unless this Warrant has been fully exercised or has expired, a new Warrant
representing the number of shares, if any, with respect to which this Warrant
has not then been exercised must also be issued to Purchaser within such
reasonable time.

         3. STOCK FULLY PAID: RESERVATION OF SHARES. All Warrant Stock which may
be issued upon the exercise of the rights represented by this Warrant will, upon
issuance, be fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issue thereof. During the period within which the
rights represented by this Warrant may be exercised, the Company will at all
times have authorized, and reserved for the purpose of the issue upon exercise
of the purchase rights evidenced by this Warrant, a sufficient number of shares
of its fully paid and nonassessable Common Stock to provide for the exercise of
the rights represented by this Warrant.

         4. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. The number and
kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price are subject to adjustment from time to time upon the happening of
the events and in the manner described in this SECTION 4.

                  4.1 RECLASSIFICATION. CONSOLIDATION OR MERGER. If any capital
reorganization or reclassification of the capital stock of the Company,
consolidation or merger of the Company with another corporation or any other
entity or the sale of all or substantially all of its assets to another entity
is effected, the successor entity (if other than the Company) resulting from
such consolidation or merger or the entity purchasing such assets must assume
this Warrant by written instrument executed and mailed or delivered to
Purchaser, and lawful and adequate provision (in form reasonably satisfactory to
Purchaser) must be made whereby the holder hereof thereafter has the right to
purchase and receive in lieu of the shares of the Common Stock of the Company
immediately theretofore purchasable and receivable upon the exercise of the
rights represented hereby, such shares of stock or assets as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such Common Stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby had such reorganization, reclassification, consolidation,
merger or sale not taken place. In any such case, appropriate provision must be
made with respect to the rights and interests of the holder of this Warrant to
assure that the provisions hereof (including without limitation provisions for
adjustment of the Exercise Price and of the number of shares purchasable and
receivable upon the exercise of this Warrant) are thereafter applicable, as
nearly as may be, in relation to any shares of stock, securities or assets
thereafter deliverable upon the exercise hereof.

                  4.2 ANTIDILUTION ADJUSTMENTS. In case the Company, subsequent
to September 30, 1997, (a) pays a dividend or make a distribution on its shares
of Common Stock in shares of Common Stock, (b) subdivides or reclassifies its
outstanding Common Stock into a greater number of shares, or (c) combines or
reclassifies its outstanding Common Stock into a smaller number of shares or
otherwise effect a reverse split, then the Exercise Price in effect at the time
of the record date for such dividend or distribution or of the effective date of
such 




                                       2
<PAGE>   3

subdivision, combination or reclassification must be proportionately adjusted so
that the Holder of this Warrant exercised after such date is entitled to receive
the aggregate number and kind of shares which, if this Warrant had been
exercised immediately prior to such time, the Holder would have owned upon such
exercise and been entitled to receive upon such dividend, subdivision'
combination or reclassification. Such adjustment is made successively whenever
any event listed in this SECTION 4.2 occur.

                  4.3 ADJUSTMENT FOR DISTRIBUTION OF PROPERTY. In case the
Company, subsequent to the issuance hereof, distributes to all holders of Common
Stock assets (excluding cash dividends or distributions paid out of current
earnings and dividends or distributions referred to in SECTION 4.2 of this
Warrant), then the Exercise Price is adjusted thereafter by multiplying the
Exercise Price in effect immediately prior thereto by a fraction, of which the
numerator is the total number of shares of Common Stock outstanding multiplied
by the Current Market Price (as determined pursuant to SECTION 9.3) per share of
Common Stock, less the fair market value of the assets distributed, and of which
the denominator is the total number of shares of Common Stock outstanding
multiplied by such current market price per share of Common Stock. Such
adjustment must be made successively whenever such a record date is fixed. Such
adjustment must be made whenever any such distribution is made and becomes
effective immediately after the record date for the determination of
stockholders entitled to receive such distribution.

                  4.4 INTENTIONALLY DELETED.

                  4.5 OTHER ADJUSTMENTS. In the case any event occurs as to
which the failure to make any adjustment would not fairly protect the purchase
rights represented by this Warrant in accordance with the essential intent and
principles of this Warrant, then, in each such case, the Purchaser may appoint
an independent investment bank or firm of independent public accountants, which
will give its opinion as to the adjustment, if any, on a basis consistent with
the essential intent and principles established in this Warrant, necessary to
preserve the purchase rights represented by this Warrant. Upon receipt of such
opinion, the Company will promptly deliver a copy of such opinion to the
Purchaser and will make the adjustments described in such opinion. The fees and
expenses of such investment bank or independent public accountants will be borne
by the Company.

                  4.6 ADJUSTMENT IN NUMBER OF SHARES. Whenever the Exercise
Price payable upon exercise of each Warrant is adjusted pursuant to SECTIONS 4.2
OR 4.3, the number of shares of Common Stock purchasable upon exercise of each
Warrant must simultaneously be adjusted by multiplying the number of shares of
Common Stock issuable upon exercise of each Warrant in effect on the date
thereof by the Exercise Price in effect on the date thereof and dividing the
product so obtained by the Exercise Price, as adjusted.

                  4.7 DE MINIMUM ADJUSTMENT. No adjustment in the Exercise Price
is required unless such adjustment would require an increase or decrease of at
least one-half cent ($0.005) in the price. Any adjustments which by reason of
this SECTION 4.7 are not required to be made are carried forward and taken into
account in any subsequent adjustment. All calculations 




                                       3
<PAGE>   4

under this SECTION 4 are made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be.

                  4.8 RETENTION OF ACCOUNTANTS. The Company may retain a firm of
independent accountants of recognized standing selected by the Board of
Directors (who may be the regular accountants employed by the Company) to make
any computation required by this SECTION 4, and a certificate signed by such
firm is presumptive evidence of the correctness of such adjustment.

                  4.9 APPLICABILITY OF ADJUSTMENTS. In the event that at any
time, as a result of an adjustment made pursuant to SECTION 4.2 of this Warrant,
the holder of any Warrant thereafter becomes entitled to receive any shares of
the Company, other than Common Stock, thereafter the number of such other shares
so receivable upon exercise of any Warrant is subject to adjustment from time to
time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Common Stock contained in this SECTION 4.

                  4.10 NO CHANGE IN LANGUAGE OF WARRANT. Irrespective of any
adjustments in the Exercise Price or the number or kind of shares purchasable
upon exercise of Warrants, Warrants theretofore or thereafter issued may
continue to express the same price and number and kind of shares as are stated
in this and similar Warrants initially issued by the Company.

                  4.11 NOTICE OF SPECIFIC EVENTS.  In case at any time:

                        (a) the Company declares any dividend payable in stock

reclassification of the capital stock of the Company, or consolidation or merger

twenty days prior written notice of the date on which the books of the Company
close or a record is taken for such dividend, distribution or subscription
rights or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, and (ii) in the case of any such reorganization, reclassification,

reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the Exercise
Price after giving effect to such adjustment, and shall cause copies of such
certificate to be delivered to Purchaser.

                  4.13 FRACTIONAL SHARES. Fractional shares of the Warrant Stock
will be issued in connection with any issuance hereunder.

         5. TRANSFERS. This Warrant or the Warrant Stock may be transferred in
whole or in part by Purchaser in compliance with applicable law.

         6. REGISTRATION UNDER THE SECURITIES ACT OF 1933.

                  6.1 PIGGY-BACK REGISTRATION RIGHTS. If, at any time during the
period commencing upon the issuance hereof and ending September 30, 2005, the
Company proposes to file a registration statement under the Security Act of
1933, as amended (the "1933 ACT"), covering securities of the Company, whether
for the Company's own account or for the account of selling securities holders,
other than registration statement relating to an acquisition or merger or a
registration statement on Form S-8 or subsequent similar form, it shall advise

referred to herein as a "HOLDER") by written notice at least one hundred twenty
days prior to the filing of such registration statement and will upon the
request of any such holder include in any such registration statement such
information as may be required to permit a public offering of the Warrant Stock.
The Company shall keep such registration statement current for a period of nine
months from the effective date of such registration statement or until such
earlier date as all of the registered Warrant Stock has been sold. In connection
with such registration, the holders shall execute and deliver such customary
underwriting documents as the managing underwriter requests as a condition to
the inclusion of the Warrant Stock in the registration statement.

                  6.2 INTENTIONALLY DELETED.

                  6.3 ADDITIONAL PROVISIONS CONCERNING REGISTRATION. The
following provisions of this SECTION 6.3 are also applicable to any registration
statement filed pursuant to SECTION 6.1:

                           (a) The Company shall bear the entire cost and 
expense of any registration of securities initiated under SECTION 6.
Notwithstanding the foregoing, any holder whose Warrant Stock is included in any
such registration statement pursuant to this SECTION 6



                                       5
<PAGE>   6

shall, however, bear the fees of its own counsel and accountants and any
transfer taxes or underwriting discounts or commissions applicable to the
Warrant Stock sold by the holder pursuant thereto.

                           (b) The Company shall indemnify and hold harmless
each such holder and each underwriter, within the meaning of the 1933 Act, who
may purchase from or sell for any such holder any Warrant Stock from and against
any and all losses, claims, damages and liabilities (including fees and expenses
of counsel, which counsel may, if the holders request, be separate from counsel
for the Company) caused by any untrue statement or alleged untrue statement of
material fact contained in the registration statement or any post-effective
amendment thereto or any registration statement under the 1933 Act or any
prospectus included therein required to be filed or furnished by reason of this
SECTION 6 or any application or other filing under any state securities law
caused by any omission or alleged omissions to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading to which such holder or any such underwriter or any of them may
become subject under the 1933 Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or alleged untrue statement or omission or alleged omission based upon
information furnished to the Company by the indemnified holder or underwriter
expressly for use therein, which indemnification includes each person, if any,
who controls any such underwriter within the meaning of each such Act. Any such
holder or underwriter must at the same time indemnify the Company, its
directors, each officer signing the related registration statement, each person,
if any, who controls the Company within the meaning of each such Act and each
other holder or underwriter, from and against any and all losses, claims,
damages and liabilities caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or any
prospectus required to be filed or furnished by reason of this SECTION 6 or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, insofar as such losses, claims, damages or liabilities are caused by
any untrue statement or alleged untrue statement or omission based upon
information furnished to the Company by such holder or underwriter expressly for
use therein.

                           (c) The Company shall qualify the Warrant Stock for
sale in such states as it is otherwise qualifying its Common Stock for sale. The
Company shall also provide the holders with prospectuses upon request from the
holders.

                           (d) The selling holders shall furnish information 
and provide indemnification as set forth in SECTION 6.3(b).

                           (e) Neither the giving of any notice by any holder 
nor the making of any request for prospectuses imposes any upon any holder
making such request any obligation to sell any Warrant Stock or exercise any
Warrant.

                           (f) The registration rights set forth in SECTION 6.1
are exercisable only by Purchaser and its permitted assigns.



                                       6
<PAGE>   7

                           (g) The Company is not required to include in any 
registration statement any Warrant Stock which could, pursuant to the provisions
of Rule 144 of the Securities and Commission under the 1933 Act, be sold during
a period of four months following the date on which registration of such Warrant
Stock was requested.

                           (h) The Company's agreements with respect to this
Warrant or the Warrant Stock in this SECTION 6 continue in effect regardless of
the exercise and surrender of this Warrant.

          7. LISTING RIGHTS. If the Company at any time lists any Common Stock
or other securities of the same class as those issuable on the exercise of this
Warrant on any national securities exchange, the Company will, at its expense,
simultaneously list on that exchange, on official notice of issuance on exercise
of this Warrant, and maintain such listing of, all shares of the Warrant Stock
or other securities from time to time issuable on exercise of this Warrant.

          8. NO RIGHTS AS STOCKHOLDERS. Purchaser is not entitled by virtue of
the terms hereof to vote or receive dividends or be deemed the holder of Common
Stock or any other securities of the Company which may at any time be issuable
on the exercise hereof until the Warrant has been exercised.

          9. CURRENT MARKET PRICE. The "CURRENT MARKET PRICE" of the Common
Stock at any date is based on the public market for the Common Stock, if any,
and is based on the average of the daily closing prices for a twenty consecutive
trading days commencing thirty trading days before such date. The closing price
for each day is the last sale price reported or, in case no such reported sale
takes place on such day, the average of the reported last bid and asked prices
regular way, in either case on the principal national securities exchange on
which the Common Stock is admitted to trading or listed or on the NASDAQ System,
or if not listed or admitted to trading on such exchange or such System, the
average of the reported highest bid and reported lowest asked prices as reported
by NASDAQ, or other similar organization if NASDAQ is no longer reporting such
information.

         10. GOVERNING LAW. This Warrant must be construed and interpreted in
accordance with and is governed in all respects by the laws of the State of
Delaware applicable to agreements executed and to be performed wholly within
such State.
