representative, discharges Martin due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding 120 days by
reason of injury, physical or mental illness or other disability, which
condition has been certified by a physician; provided, however, that prior to
discharging Martin due to such disability, the Company shall give a written
statement of findings to Martin or his personal representative setting forth
specifically the nature of the disability and the resulting performance

respond in writing to the Board of Directors' findings;

                                       2

<PAGE>

          (c)   Martin is discharged by the Board of Directors of the Company
for Cause. As used in this Agreement, the term "Cause" shall mean:

                (i)     Martin's conviction of (or pleading guilty or NOLO
CONTENDERE to) any misdemeanor involving dishonesty or moral turpitude or a
felony; provided, however, that prior to discharging Martin for Cause, the
Company shall give a written statement of findings to Martin setting forth
specifically the grounds on which Cause is based, and Martin shall have a
period of ten (10) days thereafter to respond in writing to the Board of
Directors' findings;

                (ii)    (A) the willful and continued failure of Martin to
substantially perform his duties with the Company (other than any such
failure resulting from illness or disability) after a written demand for
substantial performance is requested by the Company's Board of Directors,
which specifically identifies the manner in which it is claimed Martin has
not substantially performed his duties, or (B) the personal dishonesty,
willful misconduct or breach of a fiduciary duty in respect of any matter
which has, or can reasonably be expected to have, a direct and material
adverse effect on the Company or its reputation.  For purposes of this
Section, no act or failure to act on Martin's part shall be considered

reasonable belief that Martin's action or omission was in the best interest
of the Company;

                (iii)   the willful breach by Martin of any written covenant
or agreement with the Company not to disclose confidential information
pertaining to the Company or not to compete or interfere with the operation
of the Company's business; or

                (iv)    the abuse of alcohol or illegal drugs by Martin while
performing his employment-related duties that affects the performance by
Martin of his employment-related duties.

    No termination shall be effected for Cause unless Martin has been
provided with specific information as to the acts or omissions which form the
basis of the allegation of Cause, and Martin has had an opportunity to be
heard, with counsel if so desired, before the Board of Directors and such
Board determines, by majority vote, in good faith that Martin was guilty of
conduct constituting "Cause" as herein defined, specifying the particulars
thereof in detail;

          (d)   Martin is discharged by the Board of Directors of the Company
without Cause, which the Company may do at any time, with at least 30 days
advance written notice;

<PAGE>

          (e)   Martin voluntarily terminates his employment due to either
(i) a default by the Company in the performance of any of its obligations
hereunder, or (ii) an Adverse Change in Duties (as defined below), which
default or Adverse Change in Duties remains unremedied by the Company for a
period of ten days following its receipt of written notice thereof from
Martin;

    As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Martin's prior written consent, which
results in:

                (1)     A material change in Martin's reporting
responsibilities, titles, job responsibilities or offices which results in a
material diminution of his status, control or authority; or

                (2)     The assignment to Martin of any positions, duties or
responsibilities which are materially inconsistent with Martin's positions,
duties and responsibilities or status with the Company; or

                (3)     A requirement by the Company that Martin be based or
perform his duties anywhere other than (i) at the Company's corporate office
location on the date of this Agreement, or (ii) if the Company's corporate
office location is moved after the date of this Agreement, at a new location
that is no more than 60 miles from such prior location; or

                (4)     A failure by the Company to provide for Martin's
participation in any current or future benefits or plans at a level or to an
extent commensurate with that of other top executives of the Company;

          (f)   Martin voluntarily terminates his employment for any reason
other than the Company's default or an Adverse Change in Duties, which Martin
may do at any time with at least 30 days advance notice; or

          (g)   Martin is discharged by the Board of the Directors as a
result of a material underperformance by the Company as measured against the
Company's business plan, with such underperformance to be reasonably
determined by the Board of Directors in good faith (a "Material
Underperformance").

    4.2   EFFECTS OF TERMINATION.

          (a)   Upon termination of Martin's employment hereunder for any
reason, the Company will promptly pay Martin all compensation owed to Martin
and unpaid through the date of termination (including, without limitation,
salary, accrued paid time off, accrued but unpaid Bonus for the prior
employment

                                       4

year in the event Martin is terminated following the end of such prior
employment year and employee expense reimbursements).

          (b)   In addition, if the employment is terminated under Section
4.1(d) at a time at which there is not a Material Underperformance or under
Sections 4.1(b) or (e), the Company shall also pay Martin, immediately upon
such termination of employment, a lump sum severance amount equal to two and
one-half times the then applicable Base Salary, excluding Bonus.  In
addition, if Martin is terminated pursuant to the foregoing sentence, Martin
shall also be entitled to receive an additional six months of his then
applicable Base Salary, excluding Bonus, if he is unable to secure a position
with (i) reasonably equivalent duties and (ii) a cash compensation package
substantially similar to his Base Salary at the time of termination (an
"Equivalent Position"); provided, however, that payments pursuant to this
sentence would be paid monthly and only until such time as Martin secured an
Equivalent Position.  If the employment is terminated under Section 4.1(d) at
a time at which there is a Material Underperformance or under Section 4.1(g),
the Company shall only pay Martin, immediately upon such termination of
employment, a lump sum severance amount equal to one-half of the then
applicable Base Salary, excluding Bonus.  If Martin is terminated under
Sections 4.1(a), (c) or (f), Martin will not be entitled to any severance
payment.

          (c)   Martin agrees that, during the term of his employment and
for the one year period following the Termination Event (subject to any
limitations set forth below):

                (i)     Martin will not directly or indirectly, whether as an
individual, employee, director, consultant or advisor, or in any other
capacity whatsoever, provide services to any person, firm, corporation or
other business enterprise which is involved in the acquisition and management
of radiology physician practices or diagnostic imaging centers, unless he
obtains the prior written consent of the Board of Directors; provided,
however, that in the event that Martin is terminated under Section 4.1(d) at
a time at which there is a Material Underperformance or under Section 4.1(g),
the limitations contemplated by this Section 4.2(c)(i) will be effective only
during the term of his employment and for six months following such
Termination Event.

                (ii)    Martin will not directly or indirectly encourage or
solicit, or attempt to encourage or solicit, any individual to leave the
Company's employ for any reason or interfere in any other manner with the
employment relationships at the time existing between the Company and its
current or prospective employees.

                (iii)   Martin will not induce or attempt to induce any
provider, payor, customer, supplier, distributor, licensee or other business
relation

                                       5

<PAGE>

of the Company to cease doing business with the Company or in any way
interfere with the existing business relationship between any such customer,
supplier, distributor, licensee or other business relation and the Company.

                (iv)    Martin will not disclose or use for himself or
others, directly or indirectly (except for information disseminated by Martin
in the good faith performance of his duties for the Company prior to a
Termination Event), any trade secrets or confidential information in written,
oral, electronic or other form regarding the Company and its affiliates and
their respective businesses, equipment, products or employees.

    Martin acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason
of breach of the foregoing restrictive covenants.  Accordingly, in the event
of any such breach, the Company shall, in addition to any remedies available
to the Company at law, be entitled to obtain equitable relief in the form of
an injunction precluding Martin from continuing to engage in such breach.

    If any restriction set forth in this paragraph is held to be
unreasonable, then Martin and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall
be deemed reasonable.

4.1(d) at a time at which there is not a Material Underperformance or under
Sections 4.1(b) or (e), the Company shall also pay Jolas, immediately upon
such termination of employment, a lump sum severance amount equal to two and
one-half times the then applicable Base Salary, excluding Bonus. In addition,
if Jolas is terminated pursuant to the foregoing sentence, Jolas shall also
be entitled to receive an additional six months of his then applicable Base
Salary, excluding Bonus, if he is unable to secure a position with (i)
reasonably equivalent duties and (ii) a cash compensation package
substantially similar to his Base Salary at the time of termination (an
"Equivalent Position"); provided, however, that payments pursuant to this
sentence would be paid monthly and only until such time as Jolas secured an
Equivalent Position. If the employment is terminated under Section 4.1(d) at
a time at which there is a Material Underperformance or under Section 4.1(g),
the Company shall only pay Jolas, immediately upon such termination of
employment, a lump sum severance amount equal to one-half of the then
applicable Base Salary, excluding Bonus. If Jolas is terminated under
Sections 4.1(a), (c) or (f), Jolas will not be entitled to any severance
payment.

       (c)    Jolas agrees that, during the term of his employment and the
one year period following the Termination Event (subject to any limitations
set forth below):

              (i)    Jolas will not directly or indirectly, whether as an
individual, employee, director, consultant or advisor, or in any other
capacity whatsoever, provide services to any person, firm, corporation or
other business enterprise which is involved in the acquisition and management
of radiology physician practices or diagnostic imaging centers, unless he
obtains the prior written consent of the Board of Directors; provided,
however, that in the event that Jolas is terminated under Section 4.1(d) at a
time at which there is a Material Underperformance or under Section 4.1(g),
the limitations contemplated by this Section 4.2(c)(i) will be effective only
during the term of his employment and for six months following such
Termination Event.

              (ii)   Jolas will not directly or indirectly encourage or
solicit, or attempt to encourage or solicit, any individual to leave the
Company's employ for any reason or interfere in any other manner with the
employment relationships at the time existing between the Company and its
current or prospective employees.

              (iii)  Jolas will not induce or attempt to induce any provider,
payor, customer, supplier, distributor, licensee or other business relation
of the Company to cease doing business with the Company or in any way
interfere with the existing business relationship between any such customer,
supplier, distributor, licensee or other business relation and the Company.

              (iv)   Jolas will not disclose or use for himself or others,
directly or indirectly (except for information disseminated by Jolas in the
good faith performance of his duties for the Company prior to a Termination
Event), any trade secrets or confidential information in written, oral,
electronic or other form regarding the Company and its affiliates and their
respective businesses, equipment, products or employees.

       Jolas acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason
of breach of the foregoing restrictive covenants. Accordingly, in the event
of any such breach, the Company shall, in addition to any remedies available
to the Company at law, be entitled to obtain equitable relief in the form of
an injunction precluding Jolas from continuing to engage in such breach.

       If any restriction set forth in this paragraph is held to be
unreasonable, then Jolas and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall
be deemed reasonable.
