                  term, the obligations hereunder shall be that USDL shall cause
                  Dr. Kasdan or another designee of Seller to be nominated for

                  of the expenses of outside directors.

                    (b) Notwithstanding anything to the contrary contained in
                  subsection (a) hereof, a director, other than the individual
                  named in subsection (a) above, designated by Seller shall be
                  subject to the approval of USDL's management, which will not
                  unreasonably be withheld. Promptly after first proposing a
                  candidate, Seller shall furnish to USDL such information as
                  may be requested by USDL about Seller's designee (i) that is
                  required to be included in a Registration Statement under the

                  Seller has not received any notification that it is in

                  structures and appurtenances owned or leased by the Seller
                  which might prohibit or impair the uses presently being made
                  thereof.

                  state tax returns filed by Seller since January 1, 1993 (the

                  it and has duly paid all taxes and other charges due or
                  claimed to be due from it by federal, state, local or foreign
                  taxing authorities (including, without limitation, those due
                  in respect of the properties, income, franchises, licenses,
                  sales or payrolls of any of them); the reserves for taxes
                  reflected in the Financial Statements are adequate; and there
                  are no tax liens upon any property or assets of the Seller
                  except liens for current taxes not yet due. To the best of its
                  knowledge, all taxes that the Seller is or was required by law
                  to withhold or collect have been duly withheld or collected
                  and, to the extent required, have been paid to the proper

                    3.13. GOOD TITLE CONVEYED, ETC. The Seller has complete and
                  unrestricted power and the unqualified right to sell, assign,
                  transfer and deliver to Purchaser, and upon consummation of
                  the transactions contemplated by this Agreement, Purchaser
                  will acquire, good, valid and marketable title to the Assets
                  to be transferred to Purchaser hereunder, free and clear of
                  all Encumbrances, except those referred to in Section 3.09
                  hereof. The Bill of Sale and the other instruments to be
                  executed and delivered to Purchaser by the Seller at the
                  Closing will be valid and binding obligations of the Seller,
                  enforceable in accordance with their terms, and will
                  effectively vest in Purchaser good, valid and marketable title
                  to the Assets.

                  partners, officers, directors or employees has not employed
                  any broker or finder or incurred any liability for any
                  brokerage fees, commissions or finders' fees in connection
                  with the transactions contemplated by this Agreement.

                    3.16. MALPRACTICE LIABILITY. To the best of Seller's
                  knowledge, there is no action, suit, inquiry, proceeding or
                  investigation by or before any court or governmental or other
                  regulatory or administrative agency or commission pending or
                  threatened against or involving the Seller relating to any
                  service performed by the Seller or any of its employees and
                  alleged to have resulted in any medical malpractice, nor is
                  there any valid basis for any such action, proceeding or
                  investigation.

                    3.17. TRADE NAMES, ETC. The Seller has been using the trade
                  name "Allegheny Open MRI/CT Group" in Pennsylvania, and no
                  claims have been asserted by any person to the use of such
                  name.

                  current or former employees are covered by, any bonus,
                  deferred compensation, pension, profit-sharing, retirement,
                  insurance, stock purchase, stock option or any other fringe
                  benefit plan, arrangement or practice, other than standard
                  health benefits, or any other employee benefit plan, as
                  defined in section 3(3) of the Employee Retirement Income
                  Security Act of 1974, as amended ("ERISA"), whether formal or
                  informal (collectively, the "Plans"). Schedule 3.19 contains
                  an accurate and complete description of, and sets forth the
                  annual amount payable pursuant to, each of those Plans. The
                  Seller has performed and complied with all of its obligations
                  under or with respect to such Plans and such Plans have
                  operated in accordance with their terms. The Seller has no
                  commitment, whether formal or informal and whether legally
                  binding or not, to create any additional Plan.

                    3.19. CONSENTS AND APPROVALS OF GOVERNMENTAL AUTHORITIES AND
                  OTHERS. Except for consents listed on Schedule 3.19 to be
                  delivered pursuant to Section 1.01(c) hereof, to Seller's best
                  knowledge. Seller is not required to obtain any consent,
                  approval or authorization of, or declare, file or register
                  with, any governmental or regulatory authority in connection
                  with the execution, delivery and performance of this Agreement
                  or the consummation of the transactions contemplated hereby.
                  To Seller's best knowledge, no consent of any other person is
                  necessary on the part of Seller to the consummation of the
                  transactions contemplated hereby.

                    3.20. COMPLIANCE WITH LAW. To the best of its knowledge, the
                  operations of the Seller are and have been conducted in all
                  material respects in accordance with all applicable laws,
                  regulations and other requirements of all federal, state and
                  local governmental authorities and agencies thereof having
                  jurisdiction over the Seller, including, without limitation,
                  all such laws, regulations and requirements relating to
                  employment, equal opportunity, health, occupational safety,
                  pension and securities matters. The Seller has not received
                  any notification of any asserted present or past failure by
                  the Seller to comply with such laws, rules or regulations.
                  Seller represents that it has made good faith efforts to
                  comply with the federal anti-referral and anti-kickback rules.

                  January 1, 1996, there has been no material change in the
                  pattern of referrals from Seller's twenty-five (25) largest

                    4.04. FINANCIAL STATEMENTS. USDL has delivered to Seller
                  copies of its Annual Report on Form 10-KSB for the year ended
                  December 31, 1995 and Quarterly Report on Form 10-QSB for the
                  three months ended March 31, 1996 (the "Report"). The Reports
                  did not contain any untrue statement of a material fact or
                  omit to state a material fact required to be stated therein or
                  necessary to make the statements therein, in light of the
                  circumstances under which they were made, not misleading. The
                  financial statements in such Reports, together with the notes
                  thereto, present fairly the financial position of USDL as of
                  the respective dates indicated and the results of operations,
                  changes in stockholders' equity (to the extent included in the
                  Reports) and statements of cash flow of USDL for the
                  respective periods indicated in the Reports and such financial
                  statements have been prepared in conformity with generally
                  accepted accounting principles applied on a consistent basis.

                    4.05 ABSENCE OF MATERIAL CHANGE. Subsequent to March 31,
                  1996, except as disclosed in the Reports, USDL has not
                  incurred any liabilities or obligations, direct or contingent,
                  not in the ordinary course of business, or entered into any
                  transaction not in the ordinary course of business, which is
                  material to the business of USDL, and there has not been any
                  incurrence of short-term or long-term debt by USDL or any
                  material adverse change in its condition (financial or other),
                  net worth, results of operations, business or properties.

                    4.06 LICENSES AND PERMITS. USDL has sufficient licenses,
                  permits and other governmental authorizations as are required
                  for the conduct of its business or the ownership of its
                  properties and is in all material respects complying therewith
                  except where the failure to obtain or comply with such permits
                  would not have a material adversely affect the financial
                  condition, results of operations, business or properties of
                  USDL.

                    4.07. LITIGATION. There is no pending or threatened action,
                  suit, inquiry, proceeding or investigation by or before any
                  court or governmental or other regulatory or administrative
                  agency or commission pending or threatened against or
                  involving Purchaser or USDL, or which questions or challenges
                  the validity of this Agreement or any action taken or to be
                  taken by Purchaser or USDL pursuant to this Agreement or in
                  connection with the transactions contemplated hereby; nor is
                  there any valid basis for any such action, proceeding or
                  investigation.

                    4.08. BROKERS AND FINDERS. The Purchaser, USDL and any of
                  their partners, officers, directors or employees has not
                  employed any broker or finder or incurred any liability for
                  any brokerage fees, commissions or finders' fees in connection
                  with the transactions contemplated by this Agreement.

                    (a) FULL ACCESS. Until the Closing, the Seller shall afford
                  to Purchaser, its counsel, accountants and other
                  representatives full access to the facilities, books and
                  records of the Seller in order that Purchaser may have full
                  opportunity to make such investigations as it shall desire to
                  make of the affairs of the Seller; and the Seller will cause
                  its officers and accountants to furnish such


                                      -11-
<PAGE>
                  additional financial and operating data and other information
                  as Purchaser shall from time to time request.

                    (b) APPROVAL OF PARTNERS. Each Seller and its General
                  Partners shall (i) cause a meeting of the Seller's partners to
                  be duly called and held as soon as practicable, or arrange for
                  the written consent of the partners of the Seller, for the
                  purpose of voting on this Agreement and the transactions
                  contemplated hereby, (ii) recommend approval and adoption of
                  this Agreement and the transactions contemplated hereby to the
                  Seller's partners and (iii) use their best efforts to obtain
                  the necessary approval and adoption of this Agreement and the
                  transactions contemplated hereby by the Seller's partners.

                    (c) CONSENTS. The Seller will use its best efforts to
                  obtain, prior to the Closing, all consents necessary to the
                  consummation of the transactions contemplated hereby,
                  including, without limitation, (i) the consent of each person
                  holding a mortgage, lien or lease on real or personal property
                  owned or leased by the Seller, to the transfer of such
                  property or lease to Purchaser at the Closing; (ii) the
                  consent of each lessor of real or personal property leased by
                  the Seller to the assignment of the lessee's interest under
                  the lease of such property to Purchaser; and (iii) use its
                  best efforts to assist Purchaser in obtaining all necessary
                  approvals from any governmental agencies or departments as may
                  be necessary or desirable for Purchaser to fully operate the
                  Business as contemplated. All such consents will be in writing
                  and executed counterparts thereof will be delivered to
                  Purchaser prior to the Closing. Purchaser use its best efforts
                  to assist Seller in obtaining such consents. Notwithstanding
                  the foregoing, with respect to any property lease for which a
                  consent is not obtained prior to the Closing, until such
                  consent is obtained, Seller will continue to pay all rents due
                  thereunder and Purchaser will simultaneously reimburse Seller
                  for such amount. With respect to the common area maintenance
                  dispute for the Monroeville facility, Seller shall use its
                  best efforts to resolve such dispute prior to Closing, and if
                  such dispute is resolved after the Closing, Seller shall be
                  responsible for all amounts due to the landlord that arose
                  prior to the Closing Date and Purchaser shall be responsible
                  for all amounts due for the period that begins on the Closing
                  Date.

                    (d) OTHER TRANSACTIONS. Neither the Seller nor any General
                  Partner shall enter into any discussions concerning, or
                  approve or recommend to any of its limited partners, any
                  merger, consolidation, disposition of all or substantially all
                  of the Business or Assets (other than pursuant to this
                  Agreement), any tender offer, roll-up, acquisition or other
                  business combination, or proposal therefor, or furnish or
                  cause to be furnished any information concerning the Business
                  or Assets of the Seller to any party in connection with any
                  tender offer, roll-up or other transaction involving the
                  acquisition of the Seller or all or any substantial part of
                  its assets by any person other than Purchaser.

                    (e) NONCOMPETITION. From the Closing Date, and for a period
                  of five (5) years hereafter Richard Kasdan, M.D., Daniel H.
                  Shapira, Bernard D. Marcus and Robert L.Allman, II, will not,
                  directly or indirectly, compete with the Business of the
                  Seller, and agree to comply with the terms and conditions of
                  the Noncompetition Agreements.

                    (g) COVENANT TO SATISFY CONDITIONS. The Seller will use its
                  best efforts to insure that the conditions set forth in
                  Article VII hereof are satisfied, insofar as such matters are
                  within the control of any of them.

                    9.02 NOTIFICATION OF CERTAIN EVENTS. (a) Each party shall
                  give prompt notice to all other parties as soon as practicable
                  after it has actual knowledge of (i) the occurrence, or
                  failure to occur, of any event which would or would be likely
                  to cause any party's representations or warranties contained
                  in this Agreement to be untrue or incorrect in any material
                  respect at any time from the date hereof to the Closing Date,
                  or (ii) any failure on its part or on the part of any of its

                  written disclosure schedule (a "Schedule of Breaches") as to
                  any matter of which it becomes aware following execution of
                  this Agreement which would constitute a breach of any
                  representation, warranty, covenant, condition or agreement in
                  this Agreement by such party identifying on such Schedule of
                  Breaches the representation, warranty, covenant, condition or
                  agreement which would be so breached.

                    (b) Upon Purchaser's receipt of any Updated Schedules or any
                  Schedule of Breaches, or upon the Seller's receipt of a
                  Schedule of Breaches from the Purchaser, the party receiving
                  any such Schedule or Schedules (the "nondisclosing party")
                  shall have five business days from receipt of such Schedule or
                  Schedules to give written notice to the party delivering such
                  Schedule or Schedules (the "disclosing party") and all other
                  parties hereto that (i) it will close the transactions
                  contemplated hereby notwithstanding the new Schedule or
                  Schedules, (ii) it will not close the transactions
                  contemplated hereby based on such new Schedule or Schedules
                  and thereby terminates this Agreement pursuant to this Article
                  IX, or (iii) further investigation or negotiation is required
                  for it to reach a determination whether or not to close the
                  transactions contemplated hereby based on such new Schedule or
                  Schedules.

                    (c) If the nondisclosing party notifies the disclosing and
                  other parties that further investigation or negotiation are
                  required pursuant to (iii) in Section 9.02(b) and:

                             (i) the parties thereafter are unable to reach
                    agreement on a mutually satisfactory means of resolving the
                    matter(s) disclosed on the new Schedule or Schedules, the
                    nondisclosing party shall have the right, in its discretion,
                    to deliver written notice to all other parties hereto and
                    terminate this Agreement pursuant to this Article IX.

                             (ii) the parties are able to reach agreement on a
                    mutually satisfactory means of resolving the matter(s)
                    disclosed on the new Schedule or Schedule(s), such matter(s)
                    shall not form the basis of any claim or cause of action by
                    the nondisclosing party following the Closing, whether for
                    indemnification pursuant to Article XI above or otherwise,
                    unless the means of resolving such matter expressly provides
                    for the ability to raise any such claim or cause of action
                    following the Closing.

                                 INDEMNIFICATION

                    11.01. INDEMNIFICATION BY SELLER. (a) In the event that the
                  transactions contemplated by this Agreement are consummated,

                  actions, suits, claims, or legal, administrative, arbitration,
                  governmental or other proceedings or investigations against
                  Seller that relate to Purchaser, USDL or the Business in which
                  the principal event giving rise thereto occurred after the
                  Closing Date or which result from or arise out of any action
                  or inaction after the Closing Date of Purchaser or USDL or any
                  officer, employee, agent, representative or subcontractor of
                  Purchaser or USDL; and (iii) any and all actions, suits,
                  proceedings, elections, demands, assessments, judgments, costs
                  and expenses, including without limitation, reasonable legal
                  fees and expenses, incident to any of the foregoing or
                  incurred in investigating or attempting to avoid same or to
                  oppose the imposition thereof, or in enforcing this indemnity.
                  Notwithstanding the foregoing in the event that a court of
                  competent jurisdiction having final adjudicative authority and
                  from which no appeal is available shall determine that the
                  Seller is not entitled to indemnification then the Seller
                  shall not be entitled to recover its legal fees with respect
                  to such claim from the Purchaser or USDL.

                    11.03. PROCEDURES FOR INDEMNIFICATION. Promptly after
                  receipt by an indemnified party under Sections 11.01 or 11.02
                  of notice of the commencement of any action for which
                  indemnification may be available under Section 11.01 or 11.02
                  such indemnified party shall, if a claim in respect thereof is
                  to be made against an indemnifying party under such section,
                  give notice to the indemnifying party of the commencement
                  thereof, but the failure so to notify the indemnifying party
                  shall not relieve it of any liability (except counsel fees
                  incurred as a result of the failure to notify) that it may
                  have to any indemnified party except to the extent the
                  indemnifying party demonstrates that the defense of such
                  action is prejudiced thereby. In case any such action shall be
                  brought against an indemnified party and it shall give notice
                  to the indemnifying party of the commencement thereof, the
                  indemnifying party shall be entitled to participate therein
                  and, to the extent that it shall elect, to assume the defense
                  thereof with counsel reasonably satisfactory to such
                  indemnified party and, after notice from the indemnifying
                  party to such indemnified party of its election so to assume
                  the defense thereof, the indemnifying party shall not be
                  liable to such indemnified party under such section for any
                  fees of other counsel or any other expenses, in each case
                  subsequently incurred by such


                                      -18-
<PAGE>
                  indemnified party in connection with the defense thereof,
                  other than reasonable costs of investigation and costs and
                  expenses of legal counsel, if the indemnified party and the
                  indemnifying party are both parties to the action and the
                  indemnified party has been advised by counsel that there may
                  be one or more defenses available to it and not available to
                  the indemnifying party. If an indemnifying party assumes the
                  defense of such an action, (a) no compromise or settlement
                  thereof may be effected by the indemnifying party without the
                  indemnified party's consent (which shall not be unreasonably
                  withheld) unless (i) there is no finding or admission of any
                  violation of law or any violation of the rights of any person
                  and no effect on any other claims that may be made against the
                  indemnified party and (ii) the sole relief provided is
                  monetary damages that are paid in full by the indemnifying
                  party and (b) the indemnified party shall have no liability
                  with respect to any compromise or settlement thereof effected
                  without its consent (which shall not be unreasonably
                  withheld). Notwithstanding the foregoing, if an indemnified
                  party determines in good faith that there is a reasonable
                  probability that an action may materially and adversely affect
                  it or its affiliates other than as a result of monetary
                  damages, such indemnified party may, by notice to the
                  indemnifying party, assume the exclusive right to defend,
                  compromise or settle such action, but the indemnifying party
                  shall have the right to participate in such action and not be
                  bound by any determination of an action so defended or any
                  compromise or settlement thereof effected without its consent
                  (which shall not be unreasonably withheld).

                    11.04. SATISFACTION OF INDEMNIFICATION CLAIMS. In order to
                  provide security for Purchaser's potential indemnification
                  claims, Seller agrees that it will retain and not distribute
                  at least $1,000,000 from the Closing Payment until June 30,
                  1997. Such reserve shall consist of at least $500,000 in cash
                  and 45,000 shares of USDL Common Stock. All indemnification
                  obligations pursuant to this Article XI shall be paid within a
                  reasonable period of time after a claim for indemnification
                  has been made and its validity finally determined.

                    11.05. LIMITATIONS ON CLAIMS. All claims for indemnification
                  under this Article XI must be brought within one (1) year of
                  the Closing Date.

                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS

                    12.01. AMENDMENT AND MODIFICATION. Subject to applicable
                  law, this Agreement may be amended, modified and
                  supplemented by written agreement of the Seller, USDL and
                  Purchaser at any time prior to the Closing with respect to
                  any of the terms contained herein.

                    12.02. WAIVER OF COMPLIANCE. Any failure of the Seller, on
                  the one hand, or Purchaser and USDL, on the other, to comply
                  with any obligation, covenant, agreement or condition herein
                  may be expressly waived in writing by the Chairman of the
                  Board or President of Purchaser or the General Partner of the
                  Seller, but such waiver or failure to insist upon strict
                  compliance with such obligation, covenant, agreement or
                  condition shall not operate as a waiver of, or estoppel with
                  respect to, any subsequent or other failure.

                    12.03. EXPENSES; TRANSFER TAXES, ETC. If the transactions
                  contemplated by this Agreement are not consummated, then
                  Section 10.02(c) shall govern the payment of expenses. If
                  the


                                      -19-
<PAGE>
                  transactions contemplated by this Agreement shall be
                  consummated, the Seller agrees that all fees and expenses
                  incurred by it in connection with this Agreement shall be
                  borne by it and Purchaser and USDL agree that all fees and
                  expenses incurred by them in connection with this Agreement
                  shall be borne by them, including, without limitation as to
                  the Seller or Purchaser or USDL, all fees of counsel and
                  accountants. The Seller agrees that it will pay all transfer
                  taxes which may be payable in connection with the transactions
                  contemplated by this Agreement.

                    12.04. NOTICES. All notices, requests, demands and other
                  communications required or permitted hereunder shall be in
                  writing and shall be deemed to have been duly delivered upon

                    or to such other person or address as Purchaser shall
                    furnish to the Seller in writing.


                    12.05. ASSIGNMENT. This Agreement and all of the provisions
                  hereof shall be binding upon and inure to the benefit of the
                  parties hereto and their respective successors and permitted
                  assigns, but neither this Agreement nor any of the rights,
                  interests or obligations hereunder shall be assigned by either
                  party without the prior written consent of the other party.

                    12.06. PUBLICITY. Neither the Seller, Purchaser nor USDL
                  shall make or issue, or cause to be made or issued, any
                  announcement or written statement concerning this Agreement or
                  the transactions contemplated hereby for dissemination to the
                  general public without the prior consent of the other party.
                  This provision shall not apply, however, to any announcement
                  or written statement required to be made by law or the
                  regulations of any federal or state governmental agency or any
                  stock exchange, except that the party required to make such
                  announcement shall, whenever practicable, consult with the
                  other party concerning the timing and content of such
                  announcement before such announcement is made.

                    12.07. GOVERNING LAW. This Agreement shall be governed by
                  and construed in accordance with the laws of the Commonwealth
                  of Pennsylvania, without regard to its conflicts of law
                  doctrine. All claims, disputes or causes of action arising out
                  of this Agreement shall be brought in the federal court, if
                  jurisdiction is available, or state courts situated in
                  Allegheny County, Pennsylvania.

                    12.08. COUNTERPARTS. This Agreement may be executed
                  simultaneously in two or more counterparts, each of which
                  shall be deemed an original, but all of which together shall
                  constitute one and the same instrument.

                    12.09. HEADINGS. The headings of the Sections and Articles
                  of this Agreement are inserted for convenience only and shall
                  not constitute a part hereof or affect in any way the meaning
                  or interpretation of this Agreement.

                    12.10. ENTIRE AGREEMENT. This Agreement, including the
                  Exhibits and Schedules hereto; and the other documents and
                  certificates delivered pursuant to the terms hereof, set forth
                  the entire agreement and understanding of the parties hereto
                  in respect of the subject matter contained herein, and
                  supersede all prior agreements, promises, covenants,
                  arrangements, communications, representations or warranties,
                  whether oral or written, by any officer, employee or
                  representative of any party hereto.

                    12.11. THIRD PARTIES. Except as specifically set forth or
                  referred to herein, nothing herein expressed or implied is
                  intended or shall be construed to confer upon or give to any
                  person or corporation other than the parties hereto and their
                  successors or assigns, any rights or remedies under or by
                  reason of this Agreement.

                    12.12. SEVERABILITY. If any provision of this Agreement is
                  held invalid or unenforceable by any court of competent
                  jurisdiction, the other provisions of this Agreement will
                  remain in full force and effect. Any provision of this
                  Agreement held invalid or unenforceable only in part or degree
                  will remain in full force and effect to the extent not held
                  invalid and unenforceable.

                    12.13. ENFORCEMENT. In the event either party resorts to
                  legal action to enforce this Agreement, the prevailing party
                  shall be entitled to recover the reasonable costs of such
                  action, including, without limitation, reasonable attorneys'
                  fees at both trial and appellate levels.



        IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed as of the day and year first above written.

                     REGISTRATION AND SALE RIGHTS AGREEMENT

         THIS REGISTRATION AND SALE RIGHTS AGREEMENT is made as of June 28,
1996, by and among U.S. Diagnostic Labs Inc. a Delaware corporation ("USDL" or
the "Company") and the holders of USDL securities set forth on Schedule A hereto
(the "Holders").

                                    RECITALS

         WHEREAS, the Company and the Holders are parties to the Asset Purchase
Agreement of even date herewith (the "Purchase Agreement") relating to the
purchase by a subsidiary of the Company of substantially all of the assets of
partnerships in which the Holders were partners, the consideration of which
consisted in part of Common Stock, $.01 par value, of the Company ("USDL Common
Stock");

         WHEREAS, in order to induce the Holders to enter into the Purchase
Agreement and to induce the Company to purchase such assets pursuant to the
Purchase Agreement, the Holders and the Company hereby agree that this Agreement
shall govern (i) the rights of the Holders to cause the Company to register
shares of USDL Common Stock issued to Holders, (ii) the terms of the voting
proxy granted by the Holders and (iii) certain other matters as set forth
herein;

         NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

         1.       REGISTRATION RIGHTS.  The Company covenants and agrees with 
respect to the USDL Common Stock, as follows:

         1.1      DEFINITIONS.  For purposes of this Section 1:

         (a)      The term "Act" means the Securities Act of 1933, as amended.

         (b) The term "Holder" means any person owning or having the right to
acquire Registrable Securities or any assignee thereof in accordance with
Section 1.12 hereof.

         (c)      The term "1934 Act" shall mean the Securities Exchange Act of
1934, as amended.

         (d) The terms "register", "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document under the Act, and the declaration or order of effectiveness of
such registration statement or document.

         (e) The term "Registrable Securities" means the USDL Common Stock
issued pursuant to the Purchase Agreement any other USDL Common Stock or other
securities issued in repect of such securities, excluding in all cases (x) any
Registrable Securities sold by a person in a transaction in which his rights
under this Section 1 are not assigned or are assigned in violation of this
Agreement and (y) any Registrable Securities that have already been registered
under the Act or which are freely transferable without registration under the
Act due to the lapse of time or otherwise and which are not subject to any sales
volume limitation under Rule 144 (as hereafter defined) based on the Holder's
holding's of Registrable Securities.


                                       -1-
<PAGE>
         (f) The number of shares of "Registrable Securities then outstanding"
for the Company shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

         (g)      The term "SEC" shall mean the Securities and Exchange 
Commission.

         1.2      REQUIRED FOR REGISTRATION.

         (a) On or prior to December 1, 1996, the Company shall file with the
SEC a registration statement on Form S-3 or any other form permitted under the
Act covering the registration of the Registrable Securities and use its best
efforts to effect such registration under the Act covering the Registrable
Securities no later than January 31, 1997.

         (b) Notwithstanding the foregoing, the Company shall be permitted to
postpone the filing of any registration pursuant to this Section 1.2 if during
the period from November 1, 1996 to January 31, 1997, the Company is engaged, or
has fixed plans to engage prior to February 28, 1997, in a registered public
offering in which at least 180,000 shares of Registrable Securities will be
included, or is engaged, or has fixed plans to engage within ninety (90) days of
December 1, 1996, in an acquisition that requires the filing of two years
financial statements under Section 3-05 of Regulation S-X or the filing of a
registration statement on Form S-4 or any other activity that, in the good faith
determination of the Board of Directors of the Company, would require premature
disclosure of such activity to the material detriment of the Company, then the
Company may at its option direct that such filing be delayed for a period not in
excess of sixty (60) days from the disclosure of such acquisition or activity,
or the date of commencement of such other material activity, as the case may be,
but in no event later than March 1, 1997.

         1.3 "PIGGY-BACK" REGISTRATION RIGHTS. If (but without any obligation to
do so), during the three (3) year period commencing on the date hereof, the
Company proposes to register any of its Common Stock under the Act (a) in
connection with a public offering by the Company solely for cash or (b) on
behalf of stockholders other than the Holders in an underwritten offering or (c)
on behalf of any of its executive officers (other than a registration on Form
S-8 or S-4 or relating solely to the sale of securities to participants in a
Company stock plan), the Company shall, at such time, promptly give each Holder
written notice of such registration. Upon the written request of each Holder
given within ten (10) business days after sending of such notice by fax and
overnight courier by the Company, the Company shall, subject to the limitations
set forth in this Agreement (including the limitations of Section 1.7), include
in the Company's registration statement under the Act all of the Registrable
Securities that each such Holder has requested to be registered; provided,
however, that (i) the Company shall not be obligated to effect any registration
pursuant to this Section 1.3 after the Company has effected two (2) such
registrations and each such registration has been declared or ordered effective
and the Holders have had an opportunity to sell, (ii) the Company need not
include any Registrable Securities in any registration statement not relating to
a non-underwritten offering if such Registrable Securities are included in a
then current registration statement and (iii) nothing in this Section 1.3 shall
prevent the Company from at any time abandoning or delaying any such
registration without obligation to any Holder.


                                       -2-
<PAGE>
         1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1
to effect the registration of any Registrable Securities or to include
Registrable Securities in a registration statement, the Company shall, as
expeditiously as reasonably possible:

         (a) Prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for a period of one year or such shorter period
as required until the distribution contemplated in the Registration Statement
has been completed; provided, however, that such period shall be extended for a
period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company.

         (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

         (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

         (d) Use its reasonable best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Act.

         (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

         (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

         (g) Cause all such Registrable Securities registered pursuant hereunder
to be listed on each securities exchange on which similar securities issued by
the Company are then listed.

                                       -3-
<PAGE>
         1.5 FURNISH INFORMATION. It shall be a condition precedent to the
obligation of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding the Holder, the
Registrable Securities held by the Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of such Holder's Registrable Securities.

         1.6 EXPENSES OF REGISTRATION. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1 for each Holder, including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto, but excluding underwriting discounts and commissions relating to
Registrable Securities; provided, however, that the Company shall not bear the
cost of any professional fees or costs of accounting, financial or legal
advisors to any of the Holders. Notwithstanding the foregoing, each Holder shall
pay all registration expenses which such Holder is required to pay under
applicable law.

         1.7 UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of USDL Common Stock, the Company shall not be
required under Section 1.3 to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion, supported by a written opinion,
will not jeopardize the success of the offering by the Company. If the total
amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities to
be offered, other than by the Company, that the underwriters determine in their
sole discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, if any, including Registrable Securities, which the underwriters
determine in their sole discretion will not jeopardize the success of the
offering (the securities so included to be apportioned pro rata among the
selling stockholders according to the total amount of securities entitled to be
included therein owned by each selling stockholder or in such other proportions
as shall mutually be agreed to by such selling stockholders). For purposes of
the preceding parenthetical concerning apportionment, for any selling
stockholder that is a holder of Registrable Securities and that is a partnership
or corporation, the partners, retired partners and stockholders of such holder,
or the estates and family members of any such partners and retired partners and
any trusts for the benefit of any of the foregoing persons shall be deemed to be
single "selling stockholder", and any pro-rata reduction with respect to such
"selling stockholder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "selling stockholder", as defined in this sentence. The Company shall not
grant any other stockholder the right to include any shares of Common Stock in
such registration statement in priority to the Holders.

         1.8  INDEMNIFICATION.  In the event any Registrable Securities are 
included in a registration statement under this Section 1:

         (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the 1934 Act, against any

                                       -4-
<PAGE>

losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Act, or the 1934 Act, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, or any rule or regulation promulgated under
the Act, and the Company will pay to each such Holder, underwriter or
controlling person any reasonable legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.8(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld), nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
information furnished for use in connection with such registration by any such
Holder, underwriter or controlling person.

         (b) To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
has signed the registration statement, each person, if any, who controls the
Company within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under the Act, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with information furnished by such Holder for
use in connection with such registration; and each such Holder will pay any
legal or other expenses reasonably incurred by any person intended to be
indemnified pursuant to this subsection 1.8(b), in connection with investigating
or defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this subsection 1.8(b) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder (which consent shall not be unreasonably withheld); provided, that, in no
event shall any indemnity under this subsection 1.8(b) exceed the gross proceeds
from the offering relating to securities sold by such Holder.

         (c) Promptly after receipt by an indemnified party under this Section
1.8 of notice of the commencement of any action (including any governmental
action), such indemnified party shall, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.8, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly notified, to assume the defense thereof with counsel selected by the
indemnifying party and approved by the indemnified party (whose approval shall
not be unreasonably withheld); provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to

                                       -5-
<PAGE>
retain one separate counsel, with the fees and expenses to be paid by the
indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 1.8, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 1.8.

         (d) If the indemnification provided for in this Section 1.8 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

         (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

         (f) The obligations of the Company and Holders under this Section 1.8
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

         1.9 LOCK-UP PROVISION. (a) Each Holder hereby agrees to be subject to a
lock-up until the earlier of June 30, 1997 or such date on which the Company
announces earnings which are sufficient to release the Escrow Shares (as defined
in the Company's prospectus dated August 11, 1995) to the owners thereof as a
result of the Company having achieved the "Minimum Pretax Income" required for
their release (the "Waiver Acceleration Event") pursuant to the terms of the
Escrow Agreement governing such shares. During such lock-up period, the Holder
agrees not to directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase or
otherwise transfer or dispose of (other than to donees who agree to be similarly
bound) any securities of the Company held by it at any time during such period,
provided that the lock-up shall be released on an aggregate of 60,000 shares per
month commencing February 1, 1997 until June 30, 1997 provided that no more than
an aggregate of 120,000 shares may be sold by the Holders in any calendar month
until June 30, 1997. This Section 1.9 shall be binding upon any transferee of
the Registrable Securities and the certificates shall bear a legend to such
effect.

                                       -6-
<PAGE>
         (b) To the extent that any executive officer of the Company sells in a
transaction on the Nasdaq National Market for his own account more than 10,000
shares of USDL Common Stock in any fiscal quarter, then the lock-up in Section
1.9(a) above shall be released on such number of shares of USDL Common Stock
held by Holder calculated by multiplying the number of shares held by such
Holder by a fraction, the numerator of which is the number of shares of USDL
Common Stock sold by such executive officer and the denominator is the number of
shares of USDL Common Stock beneficially owned by such executive officer prior
to such sale. To the extent that such shares are not subject to an effective
registration statement, then the Company will be obligated to purchase the
number of shares permitted to be sold by Holder at the same gross price with no
commission or mark-up deducted that the executive officer sold shares.

         (c) In order to enforce the foregoing covenant, the Company may impose
stock-transfer instructions with respect to the Registrable Securities of each
Holder (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

                  2.       TAG ALONG RIGHTS; PROXY.

         2.1 TAG ALONG RIGHTS. In the event of a "Change in Control" of the
Company, the Company shall be obligated to purchase from each Holder all shares
of Registrable Securities held by a Holder at a per share price equal to the
highest per price share received by the Company's executive officers and
directors as of the date of this Agreement ("Management") in any sale
transaction made by any such person in the twelve (12) month period prior to, or
in conjunction with, the Change of Control. For purposes of this section 2.1
"Change of Control" shall mean any sale or transfer of USDL Common Stock by
Management which results in a reduction of 25% or more in the number of shares
of USDL Common Stock beneficially owned by such persons as a group on the date
of this Agreement; provided that the cancellation of the Escrow Shares referred
to in Section 1.9 above and the sale by Gordon Rausser of up to 200,000 shares
shall be excluded from such calculation.

         2.2 VOTING AGREEMENT AND PROXY. The Holders hereby grant to Jeffrey A.
Goffman, Chairman of the Board of the Company, an irrevocable proxy to vote the
Registrable Securities in the election of directors of the Company and in any
vote of stockholders involving proposed changes of control, mergers and other
similar extraordinary transactions. Such proxy will be voted at the direction of
a majority of the Board of Directors of the Company. Such proxy shall have a
term of three years, but shall automatically terminate upon the sale of such
shares by a Holder to an unaffiliated third party. Holders agree to execute any
documents necessary to enforce the provisions of this section.

         2.3 SELLING AGENT; BLOCK TRADES. If a Holder desires to sell any
Registrable Securities in an open market transaction prior to June 30, 1998,
such shares shall be made through D. H. Blair & Co., Inc. ("Blair") or another
market maker reasonably acceptable to the Company and the Holder (a "Sales
Agent"). Prior to the appointment of a Sales Agent other than Blair, such Sales
Agent shall agree, if requested by the Company, to execute any such sales in a
manner which does not have a material adverse impact on the market for the USDL
Common Stock. Any such sales shall be on terms to be negotiated between the
Sales Agent and the Holder. A Holder shall not be obligated to use any Sales
Agent who requests such Holder to pay any fees other than customary brokerage


                                       -7-
<PAGE>
commissions for a similar-sized transactions. Notwithstanding the foregoing,
privately negotiated "block" trades (i.e., a sale of at least 25,000 shares)
shall be permitted to be made without the Sales Agent. Prior to completion of
such a block trade, a Holder shall give the Company two (2) business days'
notice of such proposed transaction and the Company shall have such period to
purchase or arrange for the purchase of such shares on identical terms.

                  3.       MISCELLANEOUS.

         3.1 SUCCESSORS AND ASSIGNS. Except as otherwise provided in Section 3.2
below and elsewhere herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective successors and
assigns of the parties (including transferees of any shares of Registrable
Securities). Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective
successors and assign any rights, remedies, obligations, or liabilities under or
by reason of this Agreement, except as expressly provided in this Agreement.

         3.2 TRANSFER OF RIGHTS. The rights granted to the Holder pursuant to
Section 1 may not be transferred or assigned, except if the Holder is a
partnership or a business trust, it may transfer rights granted pursuant to
Section 1 to any of its partners or beneficiaries, as the case may be, to whom
USDL Common Stock is transferred. In addition, any person may transfer such
rights to an immediate family member simultaneously with the transfer of USDL
Common Stock subject to the restrictions contained herein. In the event of any
such transfers, for purposes of this Agreement, such permitted transferee shall
be deemed to be the Holder of such shares of USDL Common Stock.

         3.3 GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the Commonwealth of Pennsylvania as applied to agreements
among Pennsylvania residents entered into and to be performed entirely within
Pennsylvania without regard to principles of conflicts of law.

         3.4 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall be deemed an original, but all of which together shall constitute
one and the same instrument.

         3.5 TITLES AND SUBTITLES. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

         3.6 NOTICES. All notices, requests, demands and other communications
required or permitted hereunder shall be in writing and shall be deemed to have
been duly delivered upon personal delivery, 48 hours after deposit in the United
States mail, certified or registered mail, return receipt requested, or 24 hours

                              EMPLOYMENT AGREEMENT

        THIS EMPLOYMENT AGREEMENT entered into as of this 18th day of June 1996,
between U.S. Diagnostic Labs Inc. (the "Company"), and Joseph A. Paul (the
"Executive").

         WHEREAS, the Company desires to employ Executive and to ensure the
continued availability to the Company of the Executive's services, and the
Executive is willing to accept such employment and render such services, all
upon and subject to the terms and conditions contained in this Agreement;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants set forth in this Agreement, and intending to be legally bound, the
Company and the Executive agree as follows:

           1.     TERM OF EMPLOYMENT.
           (a) TERM. The Company hereby employs the Executive, and the Executive
hereby accepts employment with the Company, for a period commencing on July 1,
1996 and ending five years from the date hereof (the "Term").

           (b) CONTINUING EFFECT. Notwithstanding any termination of this
Agreement at the end of the Term or otherwise, the provisions of Sections 6 and
7 shall remain in full force and effect and the provisions of Sections 6(a),
6(c) and 7 shall be binding upon the legal representatives, successors and
assigns of the Executive, except as otherwise provided in this Agreement.

           2.     DUTIES.
           (a) GENERAL DUTIES. The Executive shall serve as President and a
Director of the Company with duties and responsibilities that are customary for
such executives. The Executive will use his best efforts to perform his duties
and discharge his responsibilities pursuant to this Agreement competently,
carefully and faithfully. The Executive shall be appointed to the managment
committee composed of other senior executives of the Company.

           (b) DEVOTION OF TIME. The Executive will devote substantially full
time during normal business hours (exclusive of periods of sickness and
disability and of such normal holiday and vacation periods as have been
established by the Company) to the affairs of the Company. It is expressly
understood that the Executive will not enter the employ of or serve as a
consultant to, or in any way perform any services with or without compensation
to, any other persons, business or organization (other than as set forth above
and except as set forth on Exhibit A hereto, which shall not interfere with
Executive's performance hereunder) without the prior consent of the board of
directors of the Company; provided, that the Executive shall be permitted to
devote a limited amount of his time, without compensation, to charitable or
similar organizations.

           (c) MEDICAL OPPORTUNITIES. Executive agrees to present to the Company
all potential opportunities for acquisitions, joint ventures and similar
transactions in the medical or healthcare field. Executive may pursue such
opportunities if declined by the Company.

           3.     COMPENSATION AND EXPENSES.

           (a) SALARY. For the services of the Executive to be rendered under
this Agreement, the Company shall pay the Executive an annual base salary of
$200,000 during the first year of the Term, which thereafter shall be increased
at least annually and such additional amounts as set by the discretion



                                      -1-
<PAGE>
of the board of directors. Provided, however, in no event shall the Executive's
annual base salary for the second year be less than 105% of the first year base
salary ($210,000) nor shall the annual base salary for the remaining years of
the Term be less than 105% of the previous year's minimum base salary. The
annual base salary under this Section 3(a) will be reduced, however, to the
extent that the Executive elects to defer any portion thereof under the terms of
any deferred compensation or savings plan maintained by the Company. The Company
will pay the Executive his annual salary in equal installments no less
frequently than bimonthly in accordance with the Company's policies.

           (b) BONUS. The Executive shall be paid an annual bonus of $50,000 for
the first year of the Term. For the remaining years of the Term, Executive shall
be paid a bonus equal in amount to that paid to the Company's Chief Executive
Officer. Such bonus will be paid within 120 days of the end of each fiscal year.

           (c) STOCK OPTIONS. Employee shall be granted 100,000 options under
the Company's 1995 Long Term Incentive Plan ("Plan") at $7.125 and 20,000 shares
of restricted stock under the plan which shall vest over three years. Executive
shall also be entitled to discretionary grants of options under the Plan. All
options and restricted shares granted to Executive shall vest if Executive is
terminated without cause or upon a change in control of the Company.

           (d) EXPENSES. In addition to any compensation received pursuant to
Section 3(a) and (b), the Company will reimburse or advance funds to the
Executive for all reasonable travel, entertainment and miscellaneous expenses
incurred in connection with the performance of his duties under this Agreement,
provided that the Executive properly accounts for such expenses to the Company
in accordance with the Company's practices. Such reimbursement or advances will
be made in accordance with policies and procedures of the Company in effect from
time to time relating to reimbursement of or advances to executive officers.

           (e) MOVING EXPENSES. Executive shall receive reimbursement for all
reasonable out-of-pocket moving expenses, including closing costs on a new house
in the West Palm Beach, Florida area and the commission on the sale of
Executive's existing house.

           4.     BENEFITS.
           (a) VACATION. For each 12-month period during the Term, the Executive
will be entitled to four (4) weeks of vacation without loss of compensation or
other benefits to which he is entitled under this Agreement, to be taken at such
times as the Executive may select and the affairs of the Company may permit.

           (b) EMPLOYEE BENEFIT PROGRAMS. During the Term, the Executive will be
entitled to participate in any pension, insurance or other employee benefit plan
that is maintained at that time by the Company for its executive officers,
including programs of life and medical insurance and reimbursement of membership
fees in civic, social and professional organizations.

           (c) AUTOMOBILE. The Company shall provide the Executive with a
non-accountable automobile allowance of $1,000 per month which includes all
costs associated with the use of an automobile including, without limitation,
lease or loan payments, fuel, maintenance and insurance.

           5.     TERMINATION.



                                       -2-
<PAGE>
           (a) TERMINATION FOR CAUSE. The Company may terminate the Executive's
employment pursuant to the terms of this Agreement at any time for cause by
giving written notice of termination. Such termination will become effective
upon the giving of such notice, except that termination based upon clause (iii)
below shall not become effective unless the Executive shall fail to correct such
breach within three months of receipt of written notice. At the conclusion of
such three month period, this alleged breach shall be deemed to have been cured
unless written notice to the contrary is given. Upon any such termination for
cause, the Executive shall have no right to compensation, bonus or reimbursement
under Section 3, or to participate in any employee benefit programs under
Section 4 for any period subsequent to the effective date of termination.
"Cause" shall mean: (i) the Executive is convicted of a felony which is related
to the Executive's employment or the business of the Company; (ii) the
Executive, in carrying out his duties hereunder, has been found in a civil
action to have committed gross negligence, willful gross misconduct,
misappropriated Company funds or otherwise defrauded the Company, in any case,
resulting in material harm to the Company; and (iii) the Executive materially
breaches any provision of Sections 2, 6 or 7.

           (b) DEATH OR DISABILITY. Except for the Company's obligations
contained in this Section 5, this Agreement and the obligations of the Company
hereunder will terminate upon the death or disability of the Executive. For
purposes of this Section 5(b), "disability" shall mean that for a period of six
months in any 12-month period the Executive is incapable of substantially
fulfilling the duties set forth in Section 2 because of physical, mental or
emotional incapacity resulting from injury, sickness or disease.

           Upon termination by death or disability, the Company will pay the
Executive or his legal representative, as the case may be: (i) his annual salary
at such time through the date of such termination of employment and (ii) the
Executive's pro-rata bonus due under Section 3(b) of this Agreement. Such sums
shall be paid upon the same terms and conditions as if this Agreement were in
fully force and effect.

           (c) SPECIAL TERMINATION. In the event that (i) the Executive, with or
without change in title or formal corporate action, shall no longer exercise all
of the duties and responsibilities and shall no longer possess substantially all
the authority set forth in Section 2; or (ii) the Company materially breaches
this Agreement or the performance of its duties and obligations hereunder; or
(iii) any entity or person not now an executive officer of the Company becomes
either individually or as part of a group the beneficial owner of 40% or more of
the Company's common stock or (iv) the merger, consolidation, reorganization or
liquidation of the Company (a "Change in Control"), the Executive, by written
notice to the Company, may elect to deem the Executive's employment hereunder to
have been terminated by the Company without cause, in which event the Executive
shall receive lump sum compensation equal to 2.9 times is annual salary and
incentive or bonus payments, if any, as shall have been paid to the Executive
during the Company's most recent fiscal year. If the total amount of
compensation under this paragraph were to exceed three (3) times the Executive's
base amount (the average annual taxable compensation of the Executive for the
five (5) years preceding the year in which the Change of Control occurs) the
Company and the Executive may agree to reduce the lump sum compensation to be
received by Executive in order to avoid the imposition of the "golden parachute"
tax. Alternatively, in such event, the Executive, by written notice to the
Company, may elect to refuse all further obligations of the Company under
Section 3 and Section 4 and to release the Company with respect thereto, in
which event the Company shall release the Executive from the provisions of
Section 6.




                                       -3-
<PAGE>
           6.      NONCOMPETITION AGREEMENT.

           (a) COMPETITION WITH THE COMPANY. Except as provided for in Sections
2(b) and 6(b) hereof, until termination of his employment and for a period of 12
months commencing on the date of termination, the Executive, directly or
indirectly, in association with or as a stockholder, director, officer,
consultant, employee, partner, joint venturer, member or otherwise of or through
any person, firm, corporation, partnership, association or other entity, will
not compete with the Company or any of its affiliates in the offer, sale or
marketing of radiology products or services, including radiology practice
management services, that are competitive with the products or services offered
by the Company as of the date of this Agreement, or any other business engaged
in by the Company after the date of this Agreement in which Executive is
actively involved on behalf of the Company, within any metropolitan area in the
United States or elsewhere in which the Company is then engaged in the offer and
sale of competitive products or services except as provided in (b) below.
Additionally, the foregoing shall not prevent Executive from accepting
employment with an enterprise engaged in two or more lines of business, one of
which is the same or similar to the Company's business (the "Prohibited
Business") if Executive's employment is totally unrelated to the Prohibited
Business; provided, further, the foregoing shall not prohibit Executive from
owning up to 5% of the securities of any publicly-traded enterprise provided
Executive is not an employee, director, officer, consultant to such enterprise
or otherwise reimbursed for services rendered to such enterprise.

           (b) SOLICITATION OF CUSTOMERS. During the periods in which the
provisions of Section 6(a) shall be in effect, the Executive, directly or
indirectly, will not seek Prohibited Business from any Customer (as defined
below) on behalf of any enterprise or business other than the Company, refer
Prohibited Business from any Customer to any enterprise or business other than
the Company or receive commissions based on sales or otherwise relating to the
Prohibited Business from any Customer, or any enterprise or business other than
the Company. For purposes of this Section 6(b), the term "Customer" means any
person, firm, corporation, partnership, association or other entity to which the
Company or any of its affiliates sold or provided goods or services during the
12-month period prior to the time at which any determination is required to be
made as to whether any such person, firm, corporation, partnership, association
or other entity is a Customer.

          (c) NO PAYMENT. The Executive acknowledges and agrees that no separate
or additional payment will be required to be made to him in consideration of his
undertakings in this Section 6.

          (d) RELEASE. The provisions of this Section 6 shall not apply if this
Agreement is terminated by the Company without cause or by Executive upon a
material breach by the Company.

           7. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Executive
acknowledges that during his employment he will learn and will have access to
confidential information regarding the Company and its affiliates, including
without limitation (i) confidential or secret plans, programs, documents,
agreements or other material relating to the business, services or activities of
the Company and its affiliates and (ii) trade secrets, market reports, customer
investigations, customer lists and other similar information that is proprietary
information of the Company or its affiliates (collectively referred to as
"Confidential Information"). All records, files, materials and Confidential
Information excluding personal items, obtained by the Executive in the course of
his employment with the Company are confidential and proprietary and shall
remain the exclusive property of the Company or its affiliates, as the case may
be. The Executive will not, except in connection with and as required by his
performance of his duties under this Agreement, for any reason use for his own
benefit or the benefit of any person or entity with which



                                       -4-
<PAGE>
he may be associated or disclose any such Confidential Information to any
person, firm, corporation, association or other entity for any reason or purpose
whatsoever without the prior written consent of the board of directors of the
Company, unless such Confidential Information previously shall have become
public knowledge through no action by or omission of the Executive.

           8. ASSIGNABILITY. The rights and obligations of the Company under
this Agreement shall inure to the benefit of and be binding upon the successors
or assigns of the Company, provided that such successor or assign shall acquire
all or substantially all of the assets and business of the Company. The
Executive's obligations hereunder may not be assigned or alienated and any
attempt to do so by the Executive will be void.

           9.     SEVERABILITY.

           (a) The Executive expressly agrees that the character, duration and
geographical scope of the provisions set forth in this Agreement are reasonable
in light of the circumstances as they exist on the date hereof. Should a
decision, however, be made at a later date by an arbitration proceeding that the
character, duration or geographical scope of such provisions is unreasonable,
then it is the intention and the agreement of the Executive and the Company that
this Agreement shall be construed by the tribunal in such a manner as to impose
only those restrictions on the Executive's conduct that are reasonable in the
light of the circumstances and as are necessary to assure to the Company the
benefits of this Agreement. If in an arbitration proceeding, a tribunal shall
refuse to enforce all of the separate covenants deemed included herein because
taken together they are more extensive than necessary to assure to the Company
the intended benefits of this Agreement, it is expressly understood and agreed
by the parties hereto that the provisions of this Agreement that, if eliminated,
would permit the remaining separate provisions to be enforced in such proceeding
shall be deemed eliminated, for the purposes of such proceeding, from this
Agreement.

           (b) If any provision of this Agreement otherwise is deemed to be
invalid or unenforceable or is prohibited by the laws of the state or
jurisdiction where it is to be performed, this Agreement shall be considered
divisible as to such provision and such provision shall be inoperative in such
state or jurisdiction and shall not be part of the consideration moving from
either of the parties to the other. The remaining provisions of this Agreement
shall be valid and binding and of like effect as though such provision were not
included .

           10. NOTICES AND ADDRESSES. All notices, offers, acceptance and any
other acts under this Agreement (except payment) shall be in writing, and shall
be sufficiently given if delivered to the addressees in person, by Federal
Express or similar receipted delivery, by facsimile delivery or, if mailed,
postage prepaid, by certified mail, return receipt requested, as follows:

from time to time. The transmission confirmation receipt from the sender's
facsimile machine shall be conclusive evidence of successful facsimile delivery.
Time shall be counted to, or from, as the case may be, the delivery in person or
by mailing.

           11. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument. The execution of this
Agreement may be by actual or facsimile signature.

           12. ARBITRATION. Any controversy, dispute or claim arising out of or
relating to this Agreement, or its interpretation, application, implementation,
breach or enforcement which the parties are unable to resolve by mutual
agreement, shall be settled by submission by either party of the controversy,
claim or dispute to binding arbitration in West Palm Beach, Florida (unless the
parties agree in writing to a



                                       -6-
<PAGE>
different location), before a single arbitrator in accordance with the rules of
the American Arbitration Association then in effect. In any such arbitration
proceeding the parties agree to provide all discovery deemed necessary by the
arbitrator. The decision and award made by the arbitrator shall be final,
binding and conclusive on all parties hereto for all purposes, and judgment may
be entered thereon in any court having jurisdiction thereof.

           13. ATTORNEY'S FEES. In the event that there is any controversy or
claim arising out of or relating to this Agreement, or to the interpretation,
breach or enforcement thereof, and any action or proceeding including that in

                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT entered into as of this 1st day of June 1996,
between U. S. Diagnostic Labs Inc. (the "Company"), and Michael D. Karsch (the
"Executive").

         WHEREAS, the Company desires to employ Executive and to ensure the
continued availability to the Company of the Executive's services, and the
Executive is willing to accept such employment and render such services, all
upon and subject to the terms and conditions contained in this Agreement;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants set forth in this Agreement, and intending to be legally bound, the
Company and the Executive agree as follows:

           1.     TERM OF EMPLOYMENT.
           (a) TERM. The Company hereby employs the Executive, and the Executive
hereby accepts employment with the Company, for a period commencing on the date
of this Agreement and ending June 30, 2001, provided that Executive may postpone
the commencement of the term to July 1, 1996 (the "Term").

           (b) CONTINUING EFFECT. Notwithstanding any termination of this
Agreement at the end of the Term or otherwise, the provisions of Sections 6 and
7 shall remain in full force and effect and the provisions of Sections 6(a),
6(c) and 7 shall be binding upon the legal representatives, successors and
assigns of the Executive, except as otherwise provided in this Agreement.

           2.     DUTIES.
           (a) GENERAL DUTIES. The Executive shall serve as Executive Vice
President, General Counsel and Secretary of the Company with duties and
responsibilities that are customary for such executives. The Executive will use
his best efforts to perform his duties and discharge his responsibilities
pursuant to this Agreement competently, carefully and faithfully.

           (b) DEVOTION OF TIME. The Executive will devote substantially full
time during normal business hours (exclusive of periods of sickness and
disability and of such normal holiday and vacation periods as have been
established by the Company) to the affairs of the Company. It is expressly
understood that the Executive will not enter the employ of any other persons,
business or organization without the prior consent of the chairman of the board
of directors of the Company; provided, that the Executive shall be permitted to
devote a limited amount of his time, without compensation, to charitable or
similar organizations.

           (c) MEDICAL OPPORTUNITIES. Executive agrees to present to the Company
all potential opportunities for acquisitions, joint ventures and similar
transactions in the medical or healthcare field. Executive may pursue such
opportunities if declined the Company.

           3.     COMPENSATION AND EXPENSES.
           (a) SALARY. For the services of the Executive to be rendered under
this Agreement, the Company shall pay the Executive an annual base salary of
$200,000 during the first year of the Term, which thereafter shall be increased
at least annually and such additional amounts as set by the discretion of the
Board of Directors. Provided, however, in no event shall the Executive's annual
base salary for the second year be less



                                       -1-
<PAGE>
than 105% of the first year base salary ($210,000) nor shall the annual base
salary for the remaining years of the Term be less than 105% of the previous
year's minimum base salary. The annual base salary under this Section 3(a) will
be reduced, however, to the extent that the Executive elects to defer any
portion thereof under the terms of any deferred compensation or savings plan
maintained by the Company. The Company will pay the Executive his annual salary
in equal installments no less frequently than bimonthly in accordance with the
Company's policies.

           (b) BONUS. The Executive shall be paid an annual bonus of $50,000 for
1996 and for each calendar year thereafter will receive a bonus in an amount
equal to the bonus paid to the Chief Executive Officer of the Company. Such
bonus will be paid within 60 days of the end of each fiscal year.

           (c) STOCK OPTIONS. Employee shall be granted 100,000 options under
the Company's 1995 Long Term Incentive Plan ("Plan") at an exercise price equal
to the average stock price for April 1996, as Executive was first extended a
formal offer by the Company in early April 1996. Such options will vest 50,000
in each year, provided that for the first 50,000 to vest the last sale price for
the Company's Common Stock must be at least $10.00 for one day and the last sale
price must be at least $15.00 for one day for the second 50,000 to vest.
Executive shall also be entitled to discretionary grants of options under the
Plan. The Executive shall also be granted 25,000 shares of restricted stock
under the plan at no additional cost, which shall vest over two years. In
addition, the 50,000 warrants granted to Executive in October 1995 shall be
ratified by the Board. All options and shares granted to Executive shall vest if
Executive is terminated without cause or upon a change in control of the
Company.

           (d) EXPENSES. In addition to any compensation received pursuant to
Section 3(a) and (b), the Company will reimburse or advance funds to the
Executive for all reasonable travel, entertainment and miscellaneous expenses
incurred in connection with the performance of his duties under this Agreement,
provided that the Executive properly accounts for such expenses to the Company
in accordance with the Company's practices. Such reimbursement or advances will
be made in accordance with policies and procedures of the Company in effect from
time to time relating to reimbursement of or advances to executive officers.

           (e) MOVING EXPENSES. The Company has requested that Executive and his
family relocate to the West Palm Beach, Florida area by September 1, 1996 and
the Company will reimburse Executive for all out-of-pocket costs, including but
not limited to: the packing and shipment of household goods and vehicle (or
cancellation of the lease on such vehicle) to West Palm Beach , the subsequent
closing costs of a new home and other temporary travel costs. Such reimbursed
expenses will be "grossed up" to offset any additional federal tax liability as
a result of the Company's reimbursement of expenses. In addition, if Executive
is able to sell his New York apartment, the Company will reimburse Executive for
the difference between the sales price of his existing apartment and the
outstanding mortgage amount (approximately $172,000 at June 1, 1996). If unable
to sell the apartment, the Company shall either (i) arrange for a relocation
service to purchase the apartment from Executive and pay Executive or such
service the difference between the purchase price and the mortgage amount, (ii)
purchase such apartment for the mortgage amount or (iii) shall reimburse
Executive for the difference between his carrying cost and the rent he receives
on the apartment.

         (f) LOAN. In order that Executive may purchase a house in the West Palm
Beach area, the Company shall loan Executive up to $100,000 for the down
payment. At the Company's option, the loan


                                       -2-
<PAGE>
may be secured either by a second mortgage on the house or a pledge of the
restricted stock granted pursuant to Section 3(c) above. The Executive shall
repay $20,000 of such loan from his 1996 bonus and shall repay the remaining
balance by December 31, 1997.

           4.     BENEFITS.
           (a) VACATION. For each 12-month period during the Term, the Executive
will be entitled to four (4) weeks of vacation without loss of compensation or
other benefits to which he is entitled under this Agreement, to be taken at such
times as the Executive may select and the affairs of the Company may permit.

           (b) EMPLOYEE BENEFIT PROGRAMS. During the Term, the Executive will be
entitled to participate in any pension, insurance or other employee benefit plan
that is maintained at that time by the Company for its executive officers,
including programs of life and medical insurance and reimbursement of membership
fees in civic, social and professional organizations.

           (c) AUTOMOBILE. The Company shall provide the Executive with a
non-accountable automobile allowance of $1,000 per month which includes all
costs associated with the use of an automobile including, without limitation,
lease or loan payments, fuel, maintenance and insurance.

           5.     TERMINATION.
           (a) TERMINATION FOR CAUSE. The Company may terminate the Executive's
employment pursuant to the terms of this Agreement at any time for cause by
giving written notice of termination. Such termination will become effective
upon the giving of such notice, except that termination based upon clause (iii)
below shall not become effective unless the Executive shall fail to correct such
breach within three months of receipt of written notice. At the conclusion of
such three month period, this alleged breach shall be deemed to have been cured
unless written notice to the contrary is given. Upon any such termination for
cause, the Executive shall have no right to compensation, bonus or reimbursement
under Section 3, or to participate in any employee benefit programs under
Section 4 for any period subsequent to the effective date of termination.
"Cause" shall mean: (i) the Executive is convicted of a felony which is related
to the Executive's employment or the business of the Company; (ii) the
Executive, in carrying out his duties hereunder, has been found in a civil
action to have committed gross negligence, willful gross misconduct resulting,
misappropriated Company funds or otherwise defrauded the Company, in any case,
in material harm to the Company; and (iii) the Executive materially breaches any
provision of Sections 2, 6 or 7.

           (b) DEATH OR DISABILITY. Except for the Company's obligations
contained in this Section 5, this Agreement and the obligations of the Company
hereunder will terminate upon the death or disability of the Executive. For
purposes of this Section 5(b), "disability" shall mean that for a period of six
months in any 12-month period the Executive is incapable of substantially
fulfilling the duties set forth in Section 2 because of physical, mental or
emotional incapacity resulting from injury, sickness or disease.

           Upon termination by death or disability, the Company will pay the
Executive or his legal representative, as the case may be: (i) his annual salary
at such time through the date of such termination of employment and (ii) the
Executive's pro-rata bonus due under Section 3(b) of this Agreement. Such sums
shall be paid upon the same terms and conditions as if this Agreement were in
fully force and effect.


                                       -3-
<PAGE>
           (c) SPECIAL TERMINATION. In the event that (i) the Executive, with or
without change in title or formal corporate action, shall no longer exercise all
of the duties and responsibilities and shall no longer possess substantially all
the authority set forth in Section 2; or (ii) the Company materially breaches
this Agreement or the performance of its duties and obligations hereunder; or
(iii) any entity or person not now an executive officer of the Company becomes
either individually or as part of a group the beneficial owner of 40% or more of
the Company's common stock, or (iv) the merger, consolidation, reorganization or
liquidation of the Company (a "Change in Control"), the Executive, by written
notice to the Company, may elect to deem the Executive's employment hereunder to
have been terminated by the Company without cause, in which event the Executive
shall receive lump sum compensation equal to 2.9 times his annual salary and
incentive or bonus payments, if any, as shall have been paid to the Executive
during the Company's most recent fiscal year, provided that if the Change in
Control occurs prior to December 31, 1997, Executive's total compensation shall
be deemed to be $250,000 per year for purposes of this Section. If the total
amount of the compensation under this paragraph were to exceed three (3) times
the Executive's base amount (the average annual taxable compensation of the
Executive for the five (5) years preceding the year in which the Change of
Control occurs) the Company and the Executive may agree to reduce the lump sum
compensation to be received by Executive in order to avoid the imposition of the
"golden parachute" tax. Alternatively, in such event, the Executive, by written
notice to the Company, may elect to refuse all further obligations of the
Company under Section 3 and Section 4 and to release the Company with respect
thereto, in which event the Company shall release the Executive from the
provisions of Section 6.

           6.      NONCOMPETITION AGREEMENT.
           (a) COMPETITION WITH THE COMPANY. Except as provided for in Sections
2(b) and 6(b) hereof, until termination of his employment and for a period of 12
months commencing on the date of termination, the Executive, directly or
indirectly, in association with or as a stockholder, director, officer,
consultant, employee, partner, joint venturer, member or otherwise of or through
any person, firm, corporation, partnership, association or other entity, will
not compete with the Company or any of its affiliates in the offer, sale or
marketing of radiology products or services, including radiology practice
management services, that are competitive with the products or services offered
by the Company as of the date of this Agreement, or any other business engaged
in by the Company after the date of this Agreement in which Executive is
actively involved on behalf of the Company, within any metropolitan area in the
United States or elsewhere in which the Company is then engaged in the offer and
sale of competitive products or services except as provided in (b) below.
Additionally, the foregoing shall not prevent Executive from accepting
employment with an enterprise engaged in two or more lines of business, one of
which is the same or similar to the Company's business (the "Prohibited
Business") if Executive's employment is totally unrelated to the Prohibited
Business; provided, further, the foregoing shall not prohibit Executive from
owning up to 5% of the securities of any publicly-traded enterprise provided
Executive is not an employee, director, officer, consultant to such enterprise
or otherwise reimbursed for services rendered to such enterprise.

           (b) SOLICITATION OF CUSTOMERS. During the periods in which the
provisions of Section 6(a) shall be in effect, the Executive, directly or
indirectly, will not seek Prohibited Business from any Customer (as defined
below) on behalf of any enterprise or business other than the Company, refer
Prohibited Business from any Customer to any enterprise or business other than
the Company or receive commissions based on sales or otherwise relating to the
Prohibited Business from any Customer, or any enterprise or business other than
the Company. For purposes of this Section 6(b), the term "Customer" means any
person, firm,


                                       -4-
<PAGE>
corporation, partnership, association or other entity to which the Company or
any of its affiliates sold or provided goods or services during the 12-month
period prior to the time at which any determination is required to be made as to
whether any such person, firm, corporation, partnership, association or other
entity is a Customer.

          (c) NO PAYMENT. The Executive acknowledges and agrees that no separate
or additional payment will be required to be made to him in consideration of his
undertakings in this Section 6.

           (d) RELEASE. The provisions of this Section 6 shall not apply if this
Agreement is terminated by the Company without cause or by Executive upon a
material breach by the Company.

           7. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Executive
acknowledges that during his employment he will learn and will have access to
confidential information regarding the Company and its affiliates, including
without limitation (i) confidential or secret plans, programs, documents,
agreements or other material relating to the business, services or activities of
the Company and its affiliates and (ii) trade secrets, market reports, customer
investigations, customer lists and other similar information that is proprietary
information of the Company or its affiliates (collectively referred to as
"Confidential Information"). All records, files, materials and Confidential
Information excluding personal items, obtained by the Executive in the course of
his employment with the Company are confidential and proprietary and shall
remain the exclusive property of the Company or its affiliates, as the case may
be. The Executive will not, except in connection with and as required by his
performance of his duties under this Agreement, for any reason use for his own
benefit or the benefit of any person or entity with which he may be associated
or disclose any such Confidential Information to any person, firm, corporation,
association or other entity for any reason or purpose whatsoever without the
prior written consent of the board of directors of the Company, unless such
Confidential Information previously shall have become public knowledge through
no action by or omission of the Executive.

           8. ASSIGNABILITY. The rights and obligations of the Company under
this Agreement shall inure to the benefit of and be binding upon the successors
or assigns of the Company, provided that such successor or assign shall acquire
all or substantially all of the assets and business of the Company. The
Executive's obligations hereunder may not be assigned or alienated and any
attempt to do so by the Executive will be void.

           9.     SEVERABILITY.
           (a) The Executive expressly agrees that the character, duration and
geographical scope of the provisions set forth in this Agreement are reasonable
in light of the circumstances as they exist on the date hereof. Should a
decision, however, be made at a later date by an arbitration proceeding that the
character, duration or geographical scope of such provisions is unreasonable,
then it is the intention and the agreement of the Executive and the Company that
this Agreement shall be construed by the tribunal in such a manner as to impose
only those restrictions on the Executive's conduct that are reasonable in the
light of the circumstances and as are necessary to assure to the Company the
benefits of this Agreement. If in an arbitration proceeding, a tribunal shall
refuse to enforce all of the separate covenants deemed included herein because
taken together they are more extensive than necessary to assure to the Company
the intended benefits of this Agreement, it is expressly understood and agreed
by the parties hereto that the provisions of this Agreement that, if eliminated,
would permit the remaining separate provisions to be


                                       -5-
<PAGE>
enforced in such proceeding shall be deemed eliminated, for the purposes of such
proceeding, from this Agreement.

           (b) If any provision of this Agreement otherwise is deemed to be
invalid or unenforceable or is prohibited by the laws of the state or
jurisdiction where it is to be performed, this Agreement shall be considered
divisible as to such provision and such provision shall be inoperative in such
state or jurisdiction and shall not be part of the consideration moving from
either of the parties to the other. The remaining provisions of this Agreement
shall be valid and binding and of like effect as though such provision were not
included .

           10. NOTICES AND ADDRESSES. All notices, offers, acceptance and any
other acts under this Agreement (except payment) shall be in writing, and shall
be sufficiently given if delivered to the addressees in person, by Federal
Express or similar receipted delivery, by facsimile delivery or, if mailed,
postage prepaid, by certified mail, return receipt requested, as follows:

counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument. The execution of this
Agreement may be by actual or facsimile signature.

           12. ARBITRATION. Any controversy, dispute or claim arising out of or

claim or dispute to binding arbitration in West Palm Beach, Florida (unless the
parties agree in writing to a different location), before a single arbitrator in
accordance with the rules of the American Arbitration Association then in
effect. In any such arbitration proceeding the parties agree to provide all
discovery deemed necessary by the arbitrator. The decision and award made by the

including that in arbitration as provided for in Section 12 of this Agreement,
is commenced to enforce the provisions of this Agreement, the prevailing party
shall be entitled to an award by the court or arbitrator, as appropriate, of
reasonable attorney's fee, costs and expenses.

           14. GOVERNING LAW. This Agreement and any dispute, disagreement, or
issue of construction or interpretation arising hereunder whether relating to

           15. ENTIRE AGREEMENT. This Agreement constitutes the entire Agreement

parties against which enforcement or the change, waiver discharge or termination
is sought.

          16. SECTION AND PARAGRAPH HEADINGS. The section and paragraph headings
in this Agreement are for reference purposes only and shall not affect the
meaning or interpretation of this Agreement.



           IN WITNESS WHEREOF, the Company and the Executive have executed this
Agreement as of the date and year first above written.

imaging centers on the date of this agreement and for the third year of the Term

in the number of imaging centers up to 150 at July 1, 1998 assuming 100 imaging
centers on July 1, 1997. If the number of imaging centers at July 1, 1997 is 150
or greater, then the annual base salary shall be $150,000 during the second and
third years of the Term. The annual base salary under this Section 3(a) will be
reduced, however, to the extent that the Executive elects to defer any portion
thereof under the terms of any deferred compensation or savings plan maintained

installments no less frequently than bimonthly in accordance with the Company's
policies.

           (b) BONUS. The Executive shall be paid an annual bonus of up to
$20,000 per year of the Term. Executive shall be paid a minimum bonus of $10,000
per year and the remaining $10,000, if any, shall be calculated based on the
same formula as set forth in Section 3(a). Such bonus will be paid within 120
days of the end of each fiscal year, the first such bonus payable and prorated
for the fiscal year ending December 31, 1996.

           (c) STOCK OPTIONS. Employee shall be granted 30,000 options under the
Company's 1995 Long Term Incentive Plan ("Plan") at $12.50 under the Plan which
shall vest over three years. Executive shall also be entitled to discretionary
grants of options under the Plan. All options granted to Executive shall vest if
Executive is terminated without cause or upon a change in control of the
Company.

           (d) EXPENSES. In addition to any compensation received pursuant to
Section 3(a) and (b), the Company will reimburse or advance funds to the
Executive for all reasonable travel, entertainment and miscellaneous expenses
incurred in connection with the performance of his duties under this Agreement,
provided that the Executive properly accounts for such expenses to the Company
in accordance with the Company's practices. Such reimbursement or advances will
be made in accordance with policies and procedures of the Company in effect from
time to time relating to reimbursement of or advances to executive officers.

           (e) MOVING EXPENSES. Executive shall receive reimbursement for all

           5.     TERMINATION.

           (a) TERMINATION FOR CAUSE. The Company may terminate the Executive's
employment pursuant to the terms of this Agreement at any time for cause by
giving written notice of termination. Such termination will become effective
upon the giving of such notice, except that termination based upon clause (iii)
below shall not become effective unless the Executive shall fail to correct such
breach within three months of receipt of written notice. At the conclusion of
such three month period, this alleged breach shall be deemed to have been cured
unless written notice to the contrary is given. Upon any such termination for
cause, the Executive shall have no right to compensation, bonus or reimbursement
under Section 3, or to participate in any employee benefit programs under
Section 4 for any period subsequent to the effective date of termination.
"Cause" shall mean: (i) the Executive is convicted of a felony which is related
to the Executive's employment or the business of the Company; (ii) the
Executive, in carrying out his duties hereunder, has been found in a civil
action to have committed gross negligence, willful gross misconduct,
misappropriated Company funds or otherwise defrauded the Company, in any case,
resulting in material harm to the Company; and (iii) the Executive materially
breaches any provision of Sections 2, 6 or 7.

           (b) DEATH OR DISABILITY. Except for the Company's obligations
contained in this Section 5, this Agreement and the obligations of the Company
hereunder will terminate upon the death or disability of the Executive. For
purposes of this Section 5(b), "disability" shall mean that for a period of six
months in any 12-month period the Executive is incapable of substantially
fulfilling the duties set forth in Section 2 because of physical, mental or
emotional incapacity resulting from injury, sickness or disease.

           Upon termination by death or disability, the Company will pay the
Executive or his legal representative, as the case may be: (i) his annual salary
at such time through the date of such termination of employment and (ii) the
Executive's pro-rata bonus due under Section 3(b) of this Agreement. Such sums
shall be paid upon the same terms and conditions as if this Agreement were in
fully force and effect.

           (c) SPECIAL TERMINATION. In the event that (i) the Company materially
breaches this Agreement or the performance of its duties and obligations
hereunder; or (ii) any entity or person not now an executive officer of the
Company becomes either individually or as part of a group the beneficial owner
of 40% or more of the Company's common stock; or (iii) the merger,
consolidation, reorganization or liquidation of the Company (a "Change in
Control"), the Executive, by written notice to the Company, may elect to deem
the Executive's employment hereunder to have been terminated by the Company
without cause, in which event the Executive shall be entitled to the
compensation, reimbursement and benefits payable pursuant to Section 3 and 4
herein for two years, unless if the remaining term of the Agreement is less than
one year, the Executive shall receive his salary at his then current rate,
benefits and bonus for one year. Alternatively, in such event, the Executive, by
written notice to the Company, may elect to refuse all further obligations of
the Company under Section 3 and Section 4 and to release the Company with
respect thereto, in which event the Company shall release the Executive from the
provisions of Section 6.

           6.      NONCOMPETITION AGREEMENT.

           (a) COMPETITION WITH THE COMPANY. Except as provided for in Sections
2(b) and 6(b) hereof, until termination of his employment and for a period of 12
months commencing on the date of termination, the Executive, directly or
indirectly, in association with or as a stockholder, director, officer,
consultant, employee, partner, joint venturer, member or otherwise of or through
any person, firm, corporation, partnership, association or other entity, will
not compete with the Company or any of its



                                       -3-
<PAGE>
affiliates in the offer, sale or marketing of radiology products or services,
including radiology practice management services, that are competitive with the
products or services offered by the Company as of the date of this Agreement, or
any other business engaged in by the Company after the date of this Agreement in
which Executive is actively involved on behalf of the Company, within any
metropolitan area in the United States or elsewhere in which the Company is then
engaged in the offer and sale of competitive products or services except as
provided in (b) below. Additionally, the foregoing shall not prevent Executive
from accepting employment with an enterprise engaged in two or more lines of
business, one of which is the same or similar to the Company's business (the
"Prohibited Business") if Executive's employment is totally unrelated to the
Prohibited Business; provided, further, the foregoing shall not prohibit
Executive from owning up to 5% of the securities of any publicly-traded
enterprise provided Executive is not an employee, director, officer, consultant
to such enterprise or otherwise reimbursed for services rendered to such
enterprise.

           (b) SOLICITATION OF CUSTOMERS. During the periods in which the
provisions of Section 6(a) shall be in effect, the Executive, directly or
indirectly, will not seek Prohibited Business from any Customer (as defined
below) on behalf of any enterprise or business other than the Company, refer
Prohibited Business from any Customer to any enterprise or business other than
the Company or receive commissions based on sales or otherwise relating to the
Prohibited Business from any Customer, or any enterprise or business other than
the Company. For purposes of this Section 6(b), the term "Customer" means any
person, firm, corporation, partnership, association or other entity to which the
Company or any of its affiliates sold or provided goods or services during the
12-month period prior to the time at which any determination is required to be
made as to whether any such person, firm, corporation, partnership, association
or other entity is a Customer.

         (c) NO PAYMENT. The Executive acknowledges and agrees that no separate
or additional payment will be required to be made to him in consideration of his
undertakings in this Section 6.

         (d) RELEASE. The provisions of this Section 6 shall not apply if this
Agreement is terminated by the Company without cause or by Executive upon a
material breach by the Company.

           7. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Executive
acknowledges that during his employment he will learn and will have access to
confidential information regarding the Company and its affiliates, including
without limitation (i) confidential or secret plans, programs, documents,
agreements or other material relating to the business, services or activities of
the Company and its affiliates and (ii) trade secrets, market reports, customer
investigations, customer lists and other similar information that is proprietary
information of the Company or its affiliates (collectively referred to as
"Confidential Information"). All records, files, materials and Confidential
Information excluding personal items, obtained by the Executive in the course of
his employment with the Company are confidential and proprietary and shall
remain the exclusive property of the Company or its affiliates, as the case may
be. The Executive will not, except in connection with and as required by his
performance of his duties under this Agreement, for any reason use for his own
benefit or the benefit of any person or entity with which he may be associated
or disclose any such Confidential Information to any person, firm, corporation,
association or other entity for any reason or purpose whatsoever without the
prior written consent of the board of directors of the Company, unless such
Confidential Information previously shall have become public knowledge through
no action by or omission of the Executive.

           8. ASSIGNABILITY. The rights and obligations of the Company under
this Agreement shall inure to the benefit of and be binding upon the successors
or assigns of the Company, provided that such successor or assign shall acquire
all or substantially all of the assets and business of the Company. The
Executive's obligations hereunder may not be assigned or alienated and any
attempt to do so by the Executive will be void.

           9.     SEVERABILITY.
           (a) The Executive expressly agrees that the character, duration and
geographical scope of the provisions set forth in this Agreement are reasonable
in light of the circumstances as they exist on the date hereof. Should a
decision, however, be made at a later date by an arbitration proceeding that the
character, duration or geographical scope of such provisions is unreasonable,
then it is the intention and the agreement of the Executive and the Company that
this Agreement shall be construed by the tribunal in such a manner as to impose
only those restrictions on the Executive's conduct that are reasonable in the
light of the circumstances and as are necessary to assure to the Company the
benefits of this Agreement. If in an arbitration proceeding, a tribunal shall
refuse to enforce all of the separate covenants deemed included herein because
taken together they are more extensive than necessary to assure to the Company
the intended benefits of this Agreement, it is expressly understood and agreed
by the parties hereto that the provisions of this Agreement that, if eliminated,
would permit the remaining separate provisions to be enforced in such proceeding
shall be deemed eliminated, for the purposes of such proceeding, from this
Agreement.

           (b) If any provision of this Agreement otherwise is deemed to be
invalid or unenforceable or is prohibited by the laws of the state or
jurisdiction where it is to be performed, this Agreement shall be considered
divisible as to such provision and such provision shall be inoperative in such
state or jurisdiction and shall not be part of the consideration moving from
either of the parties to the other. The remaining provisions of this Agreement
shall be valid and binding and of like effect as though such provision were not
included .

           10. NOTICES AND ADDRESSES. All notices, offers, acceptance and any
other acts under this Agreement (except payment) shall be in writing, and shall
be sufficiently given if delivered to the addressees in person, by Federal
Express or similar receipted delivery, by facsimile delivery or, if mailed,
postage prepaid, by certified mail, return receipt requested, as follows:

parties agree in writing to a different location), before a single arbitrator in
accordance with the rules of the American Arbitration Association then in
effect. In any such arbitration proceeding the parties agree to provide all
