to affairs of the Company as are necessary to faithfully and diligently perform
his duties and responsibilities hereunder; provided, however, that nothing

     3.  Term.  The initial term of this Agreement shall be for a period of
         -----

each quarterly anniversary of the Effective Date while Employee remains Employed

     4.  Compensation.  For the services rendered by Employee pursuant to
         -------------

     5.  Termination of Agreement.  The Employee's employment hereunder may be
         -------------------------                                            
terminated only as follows:

         (a) By the Company Without Cause.  The Company may at any time
             -----------------------------  
terminate the Employee's employment hereunder without Cause, by affirmative vote
of a majority of the entire Board of Directors (without counting the presence or
vote of the Employee), and upon no less than ninety (90) days' prior written
notice to the Employee.

         (b) By the Employee Without Good Reason.  The Employee may at any time
             ------------------------------------                              
terminate his employment hereunder for any reason upon no less than thirty (30)
days' prior written notice to the Company; provided; however; Section 5(d)
hereof shall apply in lieu of this Section 5(b) to any termination of employment
by the Employee for Good Reason (as defined therein).

         (c) By the Company for Cause.  The Company may at any time terminate
             -------------------------  
the Employee's employment hereunder for Cause. Prior to such event, the Company
by affirmative vote of a majority of the entire Board of Directors (without
counting the presence or vote of the Employee) shall give the Employee prompt
written notice specifying in reasonable detail the conduct which is believed to
provide the basis for a termination of Employee for Cause. Except in the event
of a termination of Employee pursuant to Section 5(c)(ii) (as to which the
termination shall be immediately effective after receipt of such letter), within
ten (10) business days of the Employee's receipt of such letter, the Employee
shall be provided an opportunity, together with his counsel, to present and
discuss with the Board of Directors the conduct which is asserted to provide a
basis for such purposed for Cause termination. Following such meeting, if
Employee does not, within ten (10) days thereof, take such reasonable steps as
directed by a majority vote of the entire Board of Directors (without counting
the presence or vote of the Employee) to cease or correct the conduct which is
asserted to provide a basis for such proposed for Cause termination, the Board
of Directors may, by the

                                       2
<PAGE>
 
affirmative vote of a majority of the entire Board of Directors (without
counting the presence or vote of the Employee), terminate the Employee's
employment for Cause. "Cause" shall mean only one or more of the following:

             (i)    The material breach of this Agreement by Employee, which
breach shall not have been cured by Employee within thirty (30) days after the
Employee's receipt from the Company at the direction of a majority of the entire
Board of Directors (without counting the presence or vote of the Employee) of
written notice specifying in reasonable detail the nature of Employee's breach;

             (ii)   The conviction of Employee for a crime of moral turpitude or
a felony which is materially injurious to the reputation or business of the
Company; and

             (iii)  Any willful act or acts by Employee which is materially and
demonstrably injurious to the Company (excluding any act ratified or approved by
the Board of Directors of the Company and further excluding any act taken by
Employee in good faith with a reasonable belief that such act was in the best
interests of the Company).

Neither the Employee's participation in or presence at any meeting at which a
for Cause termination is discussed nor the Employee's efforts to cease or cure
any conduct purported to be sufficient basis for a for Cause termination, shall
be considered an admission, acknowledgment or agreement that such conduct does
in fact provide a sufficient basis for a for Cause termination.

         (d) By the Employee for Good Reason.  The Employee may terminate
             --------------------------------  
employment hereunder for Good Reason at any time by providing prompt written
notice to the Company within a reasonable time after the occurrence of the
event(s) constituting such Good Reason. For purposes of this Agreement, "Good
Reason" means only one or more of the following:

             (i)    The material breach of this Agreement by the Company, which
breach shall not have been cured by the Company within thirty (30) days after
the Company's receipt from the Employee or his agent of written notice
specifying in reasonable detail the nature of the Company's breach.

             (ii)   The required relocation of the Employee out of the Company's
principal executive offices or the Pittsburgh Metropolitan Area without his
specific prior written consent.

             (iii)  The assignment to the Employee of any duties inconsistent in
any material respect with the Employee's position (including status and
reporting requirements), authority, duties, powers or responsibilities as
contemplated by Section 2 of this Agreement, or any other diminution of such,
authority, duties, position or responsibili ties, excluding for this purpose any
isolated, insubstantial action by the Company not taken in bad faith and which
is remedied by the Company within thirty (30) days after receipt of written
notice from the Employee to the Company that such action will be considered a
Good Reason hereunder unless timely remedied.

                                       3

             (iv)   A material increase in Employee's responsibilities,
workload, required hours or travel from that historically required of Employee,
not remedied by the company within thirty (30) days after receipt of written
notice from Employee to the Company that such increase will be considered a Good
Reason hereunder unless timely remedied.

hereunder for Good Reason pursuant to Section 5(d) or by the Company without
Cause pursuant to Section 5(a), or by mutual agreement upon any other
termination, the Employee shall remain bound by the terms of Section 10(a)
hereof, and, in any event, Employee shall remain bound by the terms of Section
10(b)-(d) hereof.

         (d) The Company shall be authorized to withhold from any payment to the
Employee, his estate or his beneficiaries hereunder all such amounts, if any,
that the Company may reasonably determine it is required to withhold pursuant to
any applicable law or regulation.

     10. Restrictions.  The Company has invested and will continue to invest
         -------------                                                      
considerable resources in the development of its business and in the research,
development and design of its activities and their delivery, which investment
has or will result in the generation of proprietary, confidential and/or trade
secret data, information, techniques and materials, both tangible and
intangible, which are owned by the Company.

         (a) The Employee agrees that during the Term, and except in the event
of Employee's termination of his employment hereunder for Good Reason or by the
Company without Cause, for a period of two (2) year from the date of the
termination of the Employee's employment hereunder, he will not directly or
indirectly (i) engage in mobile magnetic resonance imaging business (the
"Company Business") within one hundred fifty (150) miles of any location then
serviced by the Company; (ii) compete or participate as agent, employee,
consultant, advisor, representative or otherwise in any enterprise engaged in a
business which has any material operations engaged in a business competitive
with the Company Business within one hundred fifty (150) miles of any location
then serviced by the Company; or (iii) compete or participate as a stockholder,
partner or joint venturer, or have any direct or indirect financial interest, in
any enterprise which has any material operations engaged in a business
competitive with the Company Business within one hundred fifty (150) miles of
any location then serviced by the Company; provided, however, that nothing
contained herein shall prohibit the Employee from (A) owning, operating and
managing and continuing to own, operate and manage the investments and
businesses owned, operated or managed by Employee on the date hereof; (B)
owning, operating or managing any business, or acting upon any business
opportunity after obtaining approval of a majority of the Board of Directors of
the Company and a majority of the independent members of the Board of Directors
of the Company (if any); or (C) owning no more than five percent (5%) of any
publicly-traded corporation with respect to which Employee does not serve as an
officer, director, employee, consultant or in any other capacity other than as
an investor.

         (b) The Employee shall abide by and be bound as part of the employment
relationship created by this Agreement to comply with the provisions regarding
confidential information, attached as Exhibit B annexed hereto.
                                      ---------                

                                       9

         (c) To the extent the Employee develops, makes, conceives, contributes
to or reduces to practice any intellectual property related to the duties of the
Employee hereunder or which results in any way from the Employee using the
resources of the Company, such intellectual property is and shall be the sole
and exclusive property of the Company. Accordingly, the Employee shall abide by
and be bound to comply with the provisions regarding ownership of intellectual
property, attached as Exhibit C annexed hereto.
                      ---------                

         (d) During the Term, except in the event of Employee's termination of
his employment hereunder for Good Reason pursuant to Section 5(d) or by the
Company without cause pursuant to Section 5(a) and for an additional period of
two (2) year immediately following termination of the Employee's employment with
the Company, he shall abide by and be bound to comply with the additional
restrictive covenants of the Company attached as Exhibit D annexed hereto.
                                                 ---------                

         (e) Employee agrees and acknowledges that the compensation due to him
hereunder shall be full and adequate consideration for the Employee's agreement
to the foregoing restrictions.

Nothing in this Section 10 is intended to enhance or increase the rights
otherwise available to the Employee in respect of an unlawful act or omission by
the Company.

     11. Acknowledgement.  The Employee acknowledges that the restrictions set
         ----------------                                                     
forth in Section 10 hereto are reasonable in scope and essential to the
preservation of the Company's business and proprietary properties and that the
compensation paid to him pursuant to paragraph 10(e) fully compensates him for
accepting such restrictions.  The Company acknowledges that the compensation
paid to the Employee pursuant to paragraph 10(e) is a reasonable payment for his
acceptance of the restrictions in Section 10.

     12. Severability.  The covenants of the Employee contained in Section 10
         -------------                                                       
hereto shall be construed as an agreement independent of any other provision in
this Agreement and the existence of any claim or cause of action of the Employee
against the Company, whether predicated on this Agreement or otherwise, shall
not constitute a defense to the enforcement by the Company of such covenants.
If, at the time of enforcement, any sentence, paragraph, clause, or combination
of the same of such independent agreement in Section 10 is in violation of the
law of any state where applicable, such sentence, paragraph, clause, or
combination of the same shall be void in the jurisdictions where it is unlawful,
and the remainder of such paragraph in Section 10 shall remain binding on the
parties.  In the event that any part of any covenant of Section 10 is determined
by a court of law to be overly broad thereby making the covenant unenforceable,
the parties agree that such court shall substitute a judicially enforceable
limitation in its place, and that as so modified, the covenants shall be binding
upon the parties as if originally set forth in this Agreement.

     13. Notices.  All notices and other communications hereunder shall be in
         --------                                                            
writing and shall be deemed to have been given if delivered personally or sent
by registered or certified mail (return receipt requested), postage prepaid, or
by telecopy (immediately followed by telephone confirmation of delivery of such
telecopy with the intended recipient of such notice and by notice in writing
sent promptly by registered or certified mail as provided above) to the parties
to this

All such notices and communications shall be deemed to have been received on the
date of personal delivery, on the date that the telecopy is confirmed as having
been received or on the third business day after the mailing thereof, as the
case may be.

     14. Governing Law.  This Agreement shall be governed by and construed in
         --------------                                                      
accordance with the laws of the Commonwealth of Pennsylvania, without regard to
its choice of law provisions.

     15. Severability.  If any provision of this Agreement is held to be
         -------------                                                  
illegal, invalid or unenforceable under present or future laws effective during
the Term, such provision shall be fully

                                       11
<PAGE>
 
severable and this Agreement shall be construed and enforced as if such illegal,
invalid or unenforceable provision had never comprised a part hereof, and the
remaining provisions hereof shall remain in full force and effect and shall not
be effected by the illegal, invalid or unenforceable provision or by its
severance herefrom. Furthermore, in lieu of illegal, invalid or unenforceable
provision there shall be added automatically as part of this Agreement a
provision as similar in terms to the illegal, invalid or unenforceable provision
as may be possible and still be legal, valid or enforceable. The lack of
deductibility or recharacterization for tax or accounting purposes, or the
imposition of any excise taxes or penalties, fines or other charges, or
imposition of any injunction or similar restraint against the Company with
respect to the payment of any amount or provision of any benefit hereunder,
shall not be construed to make the provisions of this Agreement providing for
such payment or provision "illegal, invalid or unenforceable", nor in any manner
reduce the entitlement of the Employee, or his successor or assign to receive
such payment or benefit.

     16. Recharacterization of Payments.  To the extent that, but for this
         -------------------------------                                  
Section 16, any payment or benefit hereunder is determined by the Company's
outside auditors, Internal Revenue Service, or by any court of component
jurisdiction to be an "Excess Parachute Payment" as defined in Section 280G
(b)(1) of the Internal Revenue Code of 1986, as amended (the "Code"), such
amount as may be necessary to preclude any such payment or benefit from being
considered an "Excess Parachute Payment" shall be recharacterized and shall
constitute an unsecured, long-term loan from the Company to the Employee, his
personal representative, his successors or assigns, as the case may be, payable
together with accrued interest on the tenth anniversary of the payment of such
recharacterized payment or the receipt of such recharacterized benefit, with
interest at the Applicable Federal Rate for loans in excess of nine years, as
defined in Section 1274 of the Code, on such principal amount.  Such loan shall
be evidenced by a promissory note in the form attached hereto as Exhibit E.
                                                                 --------- 

     17. Indemnification.  The Company agrees to indemnify the Employee to the
         ----------------                                                     
fullest extent permitted by law for his services to, or on behalf of the
Company, as an Employee hereunder, as a director and in any and every other
capacity in which he may serve the Company or its interests.  In furtherance of
such agreement to indemnify, but no by way of limitation, the terms of the
Company's Certificate of Incorporation and By-Laws providing for such
indemnification and payment of expenses, as in effect on the date hereof (and,
which are attached hereto as Exhibit F), are hereby incorporated by reference as
                             ---------                                          
if fully stated herein.  Additionally, the provisions of Exhibit G shall
supplement such provisions. For the purpose of this Agreement, any amendment to
said Certificate of Incorporation or By-Laws shall not be effective to reduce,
qualify or otherwise limit the scope, benefit or enforceability of this
provision; provided, however, if any such amendment extends or improves the
           --------  -------                                               
scope, benefit or enforceability of the indemnification and payment of expenses
contained in such By-Laws for any officer, director, employee or agent, such
extended or improved provisions shall be deemed to be incorporated by reference
herein for the benefit of the Employee without any further action by the Company
or the Employee.

     18. Arbitration.  Except as otherwise provided herein, in the event of any
         ------------                                                          
controversy, dispute or claim arising out of, or relating to, this Agreement, or
the breach thereof, or arising out of any other matter relating to the
Employee's employment with the Company or the termination of such employment,
the parties may seek recourse only for temporary or preliminary injunctive
relief to the courts having jurisdiction thereof and if any relief other than
injunctive relief is sought,

                                       12
<PAGE>
 
the Company and the Employee agree that such underlying controversy, dispute or
claim shall be settled by arbitration conducted in Pittsburgh, Pennsylvania, in
accordance with this Section 16 of the Agreement and the Commercial Arbitration
Rules of the American Arbitration Association ("AAA"). The matter shall be heard
and decided, and awards rendered, by a panel of three (3) arbitrators (the
"Arbitration Panel") each of which shall have at least ten (10) years'
experience in executive compensation and employment matters. The Company and the
Employee shall each select one qualified arbitrator from the AAA National Panel
of Commercial Arbitrators (the "Commercial Panel") and AAA shall select a third
qualified arbitrator from the Commercial Panel. The award rendered by the
Arbitration Panel shall be final and binding as between the parties hereto and
their heirs, executors, administrators, successors and assigns, and judgment on
the award may be entered by any court having jurisdiction thereof.

     19. Entire Agreement.  This Agreement sets forth the entire understanding
         -----------------                                                    
of the parties with respect to the matters specified herein.  No other terms or
conditions and no amendments or modifications shall be binding unless made in
writing and signed by the parties hereto.  Upon execution and delivery by both
parties of this Agreement, the parties agree that the Employee Agreement dated
as of March 1, 1995, shall terminate without further obligation to either party.

     20. Binding Effect.  This Agreement shall be binding upon the parties
         ---------------                                                  
hereto and shall inure to the benefit of such parties, their respective heirs,
representatives, successors and permitted assigns.  This Agreement may not be
assigned by the Employee nor may it be assigned by the Company without the
Employee's consent.

     21. Expenses.  The Company shall bear the costs of all expenses associated
         ---------                                                             
with the creation, negotiation and execution of this Agreement, including the
fees of its counsel, the Employee's counsel and of any consultant retained by
the Company to advice the Employee and/or the Board of Directors with respect to
the terms and conditions of this Agreement.  The Company shall bear the full
cost of each arbitrator selected pursuant to Section 16 hereof with respect to
any dispute hereunder.  Otherwise, each party shall pay their individual
expenses with respect to this Agreement.
