                  3.2.     The Company shall also issue to Employee, in further
consideration of the performance of the services to be rendered by Employee
under this Agreement, a five year qualified incentive stock option to purchase
up to Thirty-Five Thousand (35,000) shares of the common stock of the Company at
a per share exercise price equal to the closing price of the publicly traded

each of the first two years of the Term hereof (i.e., all 35,000 shares will be
fully vested at the end of the first two years of the five year term of the
Option), provided that Employee is then in the employ of the Company.

                  3.3.     The Company shall also pay to Employee, a monthly
automobile allowance of $450, plus tolls, such payments to be made to Employee
on the first day of each month during the Term hereof.

                  3.4.     The Company shall, in addition to the Base Salary and
the Option and the automobile allowance, reimburse Employee for all ordinary and
necessary out-of-pocket expenses incurred by her in the performance of her
services under this Agreement, subject to compliance with the Company's policies

expenses.

                  3.5.      As incentive compensation to Employee for her

the date that each of such PET Centers achieves positive cash flow, an
additional bonus payment of Five Thousand Dollars ($5,000) and a warrant to
purchase Five Thousand (5,000) shares of the Company's common stock during a
period of five (5) years at an exercise price equal to the closing price of the
Company's publicly traded shares of common stock on the date of issuance of such
warrant (each such warrant will be fully vested and immediately exercisable on
the date of issuance). In addition, Employee shall be entitled to receive any
such additional bonus or incentive compensation as may be determined by the
Company's Board of Directors or its Chief Executive Officer.

         4.       Employee Benefits.

                  4.1.      Employee shall be entitled to five weeks of paid
vacation during each year of the Term hereof (except that, during each of the
first two years of the Term hereof, Employee will take three weeks of paid
vacation and the Company will pay Employee for an additional two weeks of
vacation even though Employee will work for the Company during such period and
be paid for such three weeks). At least one of the three weeks of vacation will
be taken by Employee in single, non-consecutive days. Employee hereby agrees
that she will schedule such vacations upon reasonable advance notice to the
Company so as to avoid conflicts with any of its material activities.

                  4.2.      Employee shall be entitled to participate in all
benefit programs established by the Company during the Term hereof for its
employees, including, without limitation, any retirement, pension, profit
sharing, insurance, hospitalization, disability or other employee benefit plan
of any type (including, without limitation, any incentive, profit sharing, bonus
or stock option plan) which may hereafter be adopted by the Company for its
<PAGE>

employees, it being understood that such entitlements are exclusive of any of
such fringe benefits that may be provided to any other employee or executive of
the Company pursuant to a separate employment agreement or arrangement between
the Company and any such employee or executive.

         5.       Term.

                  5.1.     The term of this Agreement shall commence on the date
of the execution of this Agreement and shall expire on January 31, 2008, subject

the Company shall pay to Employee any unpaid Base Salary, automobile allowance,
and incentive compensation which are accrued and unpaid through the effective

effective date of any such termination.

         6.       Confidentiality and Non-Disclosure Covenant. During the Term
of this Agreement, Employee hereby acknowledges that she will obtain and be
entrusted with unpublished and material confidential and proprietary information
relating to the Company's present and proposed business and operations
including, without limitation, financial information relating to the Company's
present and proposed business and operations, the cost and pricing of the
Company's services, proposed acquisitions of the Company, and the terms of all
material agreements to which the Company is a party. All of such information
that may be obtained by Employee shall, for purposes hereof, be referred to
herein as "Confidential Information". Employee hereby agrees that, unless the
Confidential Information becomes publicly known through legitimate origin not
involving any improper act or omission of Employee, neither she, nor any entity
or person owned or controlled directly or indirectly by her, shall, during the
Term of this Agreement or thereafter, use for her own benefit or for the benefit
of others for any purpose or in any manner whatsoever, divulge to any person,
firm, corporation or other entity or otherwise publish or disclose any
Confidential Information (except as necessary in connection with the performance
of Employee's services under this Agreement). Notwithstanding the foregoing,
Employee shall not be in breach of this covenant with respect to any use or
disclosure of any Confidential Information by her which is or becomes available
in the public domain or is required to be disclosed as a result of any legal
process served upon her in any judicial or administrative proceeding or was
obtained by Employee from a third party without such third party's breach of
agreement or obligation of trust. For purposes hereof (and for Section 7
hereof), the term "Company" shall include both the Company and its subsidiaries
and affiliated entities.
<PAGE>

         7.       Non-Competition; Non-Solicitation.

                  7.1.      Employee acknowledges and recognizes the highly
competitive nature of the business and proposed business of the Company and
hereby agrees that, during the Term hereof and for a period of one year after
the expiration or any earlier termination of the Term of this Agreement (such
period to be referred to hereinafter as the "Applicable Period"), she will not,
directly or indirectly, on her own behalf or in the service of or on behalf of
others, whether as an officer, director, stockholder, partner, trustee,
principal, employee, consultant, agent, or owner of any capital stock,
partnership interest or other interest in any corporation, partnership or other
entity, or in any other capacity, own an interest in, perform any services or
conduct any activity for or on behalf of any entity which is engaged in the
ownership, operation, licensing, joint venture or similar arrangement, or
management of a medical diagnostic positron emission tomography imaging facility
which is located or provides services to customers within an area consisting of
the greater of a twenty (20) mile radius of any PET Center which is owned and/or
operated, in whole or in part, by the Company (for these purposes to include any
parent, subsidiary or affiliate thereof) (a "Facility") or in any county in
which there is a Facility (a "Precluded Business Activity"). Employee
acknowledges that, due to the nature of the Company's business, it is essential
to provide for as broad a geographical limitation as possible with respect to
the aforementioned covenant inasmuch as the Company will make substantial
capital investments and commitments for each of its aforementioned PET Centers.
Without limiting the generality of the foregoing, it is expressly understood and
agreed that although Employee and the Company consider the restrictions
contained in this Section 7.1 to be reasonable, the Employee agrees that in the
event it is finally judicially determined by a court of competent jurisdiction
that the specified time period or geographical area or scope of the foregoing
restriction is unreasonable, arbitrary, or against public policy, contrary to
law, invalid and unenforceable, the remaining provisions of this Agreement
(including the remaining provisions of this Section) shall not be rendered void,
shall not be affected thereby and shall remain in full force and effect and the
provisions hereof which are the subject of any such judicial determination shall
be deemed amended to apply to any such lesser time period, geographical area, or
scope which is judicially determined or indicated to be reasonable,
non-arbitrary and not violative of public policy, not contrary to law, invalid
and/or unenforceable and such provisions, as modified, may be enforced by the
Company against the Employee in accordance with the terms hereof.
Notwithstanding the foregoing, nothing contained in this Section is intended to
nor shall preclude the ownership by Employee of not more than one (1%) percent
of the outstanding securities of any publicly owned corporation or other entity
engaged in a Precluded Business Activity, provided that such ownership is solely
for investment purposes and is not coupled with any working relationship between
Employee and such corporation or entity.

                  7.2.      Employee will not, at any time during the Term
hereof, or within three (3) years after the Expiration Date, directly or
indirectly, (i) solicit the business of any client or customer of the Company
for purposes of utilizing positron emission tomography procedures or services,
or (ii) solicit, interfere with, or endeavor either to cause any employee,
<PAGE>

agent, customer or supplier of the Company to leave his or her employment with
the Company, or terminate its relationship with the Company, or (iii) induce or
attempt to induce any such employee, agent, customer or supplier to breach any
employment agreement or other agreement or arrangement that such employee,
agent, customer or supplier may have with the Company.

                  7.3.      Employee hereby acknowledges that the provisions of
Section 6 and of this Section 7 are necessary for the protection of the
Company's business and goodwill and are considered by Employee to be fair and
reasonable. Employee further acknowledges that she has fully and carefully
reviewed, considered and understands all of the restrictions imposed upon her
under Section 6 and this Section 7. Accordingly, Employee hereby acknowledges
and agrees that in the event of any actual or threatened breach of the
provisions of Section 6 and/or this Section 7, there will be no adequate remedy
at law for any such breach or threatened breach and that any such breach or
threatened breach may cause irreparable harm to the Company and, therefore,
Employee hereby consents in any such instance to the granting of injunctive or
other equitable relief to the Company, as a non-exclusive remedy, in any Federal
or state court located in New York County, New York or any other court of
competent jurisdiction selected by the Company, without the necessity of showing
any actual damage or that monetary damages would not provide an adequate remedy
at a law or posting a bond thereof. Furthermore, the parties hereto acknowledge
and agree that the provisions of Sections 6 and 7 of this Agreement shall
survive the termination or expiration of this Agreement.

         8.       Representations and Warranties.  The Company and Employee
hereby represent and warrant to each other as follows:

                  8.1.     All action on the part of the Company and Employee
necessary for the authorization, execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated hereby, has been
taken and this Agreement constitutes a valid and legally binding obligation of
the Company and Employee, as applicable, enforceable in accordance with its
terms, except as the same may be limited by bankruptcy, insolvency,
reorganization, moratorium, or other laws affecting generally the enforcement of
creditors' rights and by general principles of equity.

                  8.2.     The authorization, execution, delivery and
performance of this Agreement, and the consummation of the transactions
contemplated hereby, will not result in any violation or be in conflict with or
constitute, with or without the passage of time and giving of notice, a default
under any provision of any instrument, judgment, order, writ, decree or
agreement to which the Company or Employee, as applicable, is a party or by
which it or she is bound.

                  8.3.     There is no action, suit, proceeding, or
investigation pending, or to the knowledge of the Company or Employee, as
applicable, currently threatened against the Company or Employee, as applicable,
in any way relating to the validity of this Agreement or the right of the
Company or Employee, as applicable, to enter into or to consummate this
Agreement and/or perform and/or comply with their respective services and
obligations hereunder.
