                              W I T N E S S E T H:

            WHEREAS, entering into this Agreement is a condition of closing
under a certain Agreement and Plan of Merger, dated the date hereof (the "Merger

a wholly-owned subsidiary of EDG ("Merger Sub"), merged (the "Merger") with and
into the Molecular Radiation Management, Inc. ("MRM");

            WHEREAS, MRM shall be the successor and surviving corporation in the
Merger and shall become a wholly-owned subsidiary of the Company;

            WHEREAS, the Executive was employed by MRM and the Company wishes to
ensure the continued employment of the Executive with the Company and the
Executive wishes to accept such employment upon the terms and condition
hereinafter set forth;

            NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, receipt of which is hereby acknowledged, the parties
hereto agree as follows:

      1. Employment

            The Company agrees to employ the Executive during the Term specified
in paragraph 2, and the Executive agrees to accept such employment, upon the
terms and conditions hereinafter set forth.

      2. Term

            Subject to paragraphs 6 and 7, the Executive's employment by the
Company shall be for a term commencing on the date hereof and expiring on the
close of business on September 7th, 2003 (the "Initial Term"); provided,
however, the Executive's employment by the Company shall then continue for an
indefinite period thereafter unless and until either party shall give to the
other one hundred and eighty (180) days advance written notice of expiration of
the term specifically stating the date on which the Executive's employment by
the Company shall terminate (a "Notice of Termination") (the Initial Term and
the period, if any, thereafter, during which the

<PAGE>

Executive's employment shall continue are collectively referred to as the
"Term"). Any Notice of Termination given under this paragraph 2 shall specify
the date of expiration (which may not be earlier than the close of business on
September 8th, 2003 and may be given at any time on or after March 8th, 2003).
The date on which the Executive ceases to be employed by the Company, regardless
of the reason therefore, is referred to in this Agreement as the "Date of
Termination".

      3. Duties and Responsibilities

            (a) During the Term, the Executive shall have the position of (i)
President and Chief Executive Officer of the Company. The Executive shall report
directly to the Board of Directors of the Company (the "Board") at such times
and in such detail as it shall reasonably require consistent with the
Executive's position as President and Chief Executive Officer. During the Term,
the Company shall not hire or engage another officer, employee or agent in a
position equal or senior to the Executive's position and the Executive shall
have senior executive authority over all matters of the Company's business and
operations.

responsibilities customary to his offices as are reasonably necessary to the
operations of the Company and its subsidiaries as may be assigned to him from
time to time by or under the authority of the Board consistent with his position
of President and Chief Executive Officer. Without limiting the foregoing, the
Executive shall be responsible for the general overall strategy, management,
administration and day-to-day operations of the Company. It is the intention of
the parties that the Executive shall be elected to and serve as Chairman of the
Board of the Company.

            (c) The Executive's employment by the Company shall be full-time and
exclusive, and during the Term, the Executive agrees that he will devote his
business time and attention and all his skill and ability to promote the
interests of the Company, and work with other employees of the Company in a
competent and professional manner. Notwithstanding the foregoing, the Executive
shall be permitted to engage in charitable and civic activities, manage his
personal investments and serve on advisory boards or boards of directors of
other entities, provided that such activities do not involve an entity which
transacts business with the Company or engages in business competitive with that
conducted by the Company (or, if such entity does transact business with the
Company, or does engage in a competitive business, it is a publicly held
corporation of which the Executive owns less than 5% of the outstanding shares).

            (d) During the Term, the Executive's services hereunder shall be
performed at the offices of the Company in Garden City, New York, subject to
necessary and reasonable travel requirements of his position and duties
hereunder.

Salary"). The Base Salary shall be paid in accordance with the Company's normal
payroll practices. The Base Salary shall be reviewed not less frequently than
annually for the purpose of making increases at the reasonable discretion of the
Board taking into consideration the size and growth of the Company's revenues,
the Executive's accomplishments and compensation of other chief executive
officers in similar businesses in the biopharmaceutical industry; provided,
however, that such increases shall be no less than five (5%) percent annually.
The Base Salary as from time to time in effect may not be decreased without the
Executive's consent.

the Company and (ii) the approval of the option awards by the Board or a
committee thereof, 175,000 stock options to purchase shares of common stock of
the Company, at a price equal to $.8065 per share of common stock (the "Initial
Options"). The Executive will also be eligible to receive additional grants of
options under the Company's Stock Option Plan (the "Additional Options"; and
together with the Initial Options, the "Options") and additional cash bonuses,

Company (the "Board").

      5. Expenses; Fringe Benefits

programs) provided by the Company to its employees generally and (without
duplication) to its senior executives generally.

            (c) During the Term, the Executive shall be eligible to participate
in all retirement plans and programs (including without limitation any profit

provided by the Company to its employees generally and (without duplication) to
its senior executives generally. In addition, during the Term, the Executive

executives generally.

      6. Termination

            (a) The Company by direction of the Board shall be entitled to
terminate the Term and to discharge the Executive for "Cause" (as defined below)
effective upon the Company's compliance with the following: The Executive shall
be given written notice of the Company's intention to terminate him for Cause
(the "Cause Notice"), such notice to state in detail the specific conduct of the
Executive that it considers to constitute Cause and the specific provision(s) of
this Agreement on which it relies, and stating the date, time and place of a
special meeting of the Board to be held for the specific and sole purpose of
considering the termination of the Executive for Cause. Such meeting shall take
place not less than ten and not more than twenty business days after the
Executive receives the Cause Notice. At such special meeting, the Executive,
represented by counsel of his choosing, shall have the opportunity to be heard.
The Executive's termination for Cause shall be effective when and if a
resolution is duly adopted at such special meeting of the Board by a majority
vote (excluding the vote of the Executive) of the Board. The term "Cause" shall
be limited to the following grounds:

                  (i) the Executive's willful failure or refusal to materially
      perform his duties and responsibilities as set forth in paragraph 3
      hereof, if such failure or refusal is not cured (if curable) within 20
      days after written notice thereof to the Executive by the Company;

                  (ii) the willful misappropriation of the funds or property of
      the Company or any subsidiary;

                  (iii) the use of alcohol or illegal drugs, materially
      interfering with the performance of the Executive's obligations under this
      Agreement, continuing after written warning; and

                  (iv) the conviction in a court of law of, or entering a plea
      of guilty or no contest to, any felony or any crime involving moral
      turpitude, dishonesty or theft.

<PAGE>

If being understood that no act or failure to act on the part of the Executive
shall be considered "willful" unless it is done, or omitted to be done, by the
Executive in bad faith or without reasonable belief that the Executive's action
or omission was in the best interests of the Company.

            (b) The Executive shall be entitled to terminate this Agreement for
"Good Reason" (as defined below) at any time during the Term by written notice
to the Company stating in detail the specific conduct of the Company or event
that he considers to constitute Good Reason and the specific provision(s) of
this Agreement on which he relies. "Good Reason" means:

                  (i) the assignment to the Executive of any duties inconsistent
      in any respect with the Executive's position (including status, offices,
      titles and reporting requirements), authority, duties or responsibilities
      as contemplated by paragraph 3 above or any other action by the Company
      which results in a diminution in such position, authority, duties or
      responsibilities, other than an isolated, insubstantial and inadvertent
      action that is not taken in bad faith and is remedied by the Company
      within 10 days after receipt of notice thereof given by the Executive;

                  (ii) the Company's requiring the Executive to be based at any
      office or location outside the New York City metropolitan area (unless
      otherwise consented to by the Executive in writing);

                  (iii) any failure by the Company to comply with any of its
      obligations under paragraph 4 of this Agreement and which is not remedied
      by the Company within five days after receipt of notice thereof given by
      the Executive;

                  (iv) any action by the Company that reduces the fringe
      benefits or perquisites provided to the Executive or the Executive's
      eligibility to participate in any employee benefit plan of the Company
      unless the Executive is provided with equal or more favorable fringe
      benefits, perquisites or employee benefits, as the case may be;

                  (v) any material breach of any other provision not covered by
      any other clause of this paragraph 6(b) which is not remedied by the
      Company within 10 days after receipt of notice thereof given by the
      Executive;

                  (vi) the Executive is removed as a member of the Board; or

                  (vii) a Change in Control (as defined on Annex I hereto).

employment by the Company for Cause; (2) the Executive's voluntary resignation
pursuant to a Notice of Termination under paragraph 2 above (other than for Good
Reason); or (3) the termination of the Executive's employment by the Company in
connection with the Executive's death or "Disability" (as defined in paragraph 7
below), the Executive shall be entitled to:

<PAGE>

                  (i) any and all unpaid Base Salary and accrued vacation time
      through, and any unpaid reimbursable expenses outstanding as of, the Date
      of Termination;

                  (ii) any unpaid Cash Bonus under paragraph 4(b) for any
      calendar year preceding the year in which the Date of Termination occurs
      (the "Termination Year"), payable at the time such cash bonus is otherwise
      payable under paragraph 4(b) hereof;

                  (iii) except for a termination for Cause, a pro-rata portion
      of any unpaid Cash Bonus under paragraph 4(b) for the Termination Year
      (had the Executive's employment continued hereunder during the entire
      Term) based upon the number of days in such year that he was employed by
      the Company, payable at the time it is otherwise payable under paragraph
      4(b) hereof as if the Executive's employment had continued hereunder
      during the entire Term (which pro-rata amount shall be no less than the
      equivalent pro-rata calculation for Cash Bonus paid for the year prior to
      the Termination Year); and

                  (iv) any and all benefits, if any, that had accrued to the
      Executive through the Date of Termination under the plans and programs
      described in paragraphs 5(b) and 5(c) above, or any other applicable plans
      and programs in which he participated as an employee of the Company, in
      the manner and in accordance with the terms of such plans and programs.

            (f) In the event of (1) a termination of the Executive's employment
by the Company for any reason other than for Cause, the Executive's death or
Disability; (2) a termination of the executive's employment pursuant to a Notice
of termination under paragraph 2 above; or (3) the termination of the
Executive's employment by the Executive for Good Reason, the Executive shall be
entitled to continue to receive from the Company, the following:

                  (i) severance compensation as follows: if the Date of
      Termination occurs during the Initial Term, his applicable salary
      compensation when otherwise payable through September 7th, 2004; if the
      Date of Termination occurs after the Initial Term, his applicable salary
      compensation when otherwise payable through the twelve-month anniversary
      of the Date of Termination (the applicable period during which the
      Executive is entitled to severance compensation is referred to herein as
      the "Severance Period");

                  (ii) any unpaid Cash Bonus under paragraph 4(b) for any
      calendar year preceding the Termination Year, payable at the time such
      cash bonus is otherwise payable under paragraph 4(b) hereof;

                  (iii) any Cash Bonus under paragraph 4(b) for the Termination
      Year and each year during the Severance Period, payable at the time it is
      otherwise payable under paragraph 4(b) hereof as if the Executive's
      employment had continued hereunder during the entire Severance Period
      (which Cash Bonus shall be no less than the Cash Bonus paid with respect
      to the year prior to the Termination Year); and


                                       6
<PAGE>

                  (iv) any unpaid reimbursable expenses and accrued vacation
      time outstanding as of the Date of Termination;

                  (v) all benefits, if any, that had accrued to the Executive
      through the Date of Termination under the plans and programs described in
      paragraphs 5(b) and 5(c) above, or any other applicable benefit plans and
      programs in which he participated as an employee of the Company, in the
      manner and in accordance with the terms of such plans and programs;

                  (vi) continued participation on the same basis (including
      without limitation, cost contributions) as the other senior executives of
      the Company in all, medical, dental, hospitalization, prescription,
      disability and life insurance coverage (such benefits collectively called
      the "Continued Plans") in which he was participating on the Date of
      Termination (as such Continued Plans are from time to time in effect at
      the Company) until the earlier of (x) the end of the Severance Period or
      (y) the date, or dates, he is entitled to receive coverage and benefits
      under the same type of plan of a subsequent employer; provided, however,
      if the Executive is precluded from continuing his participation in any
      Continued Plan, then the Company will be obligated to pay him the economic
      equivalent of the benefits provided under the Continued Plan in which he
      is unable to participate, for the period specified above, plus an amount
      equal to the tax, if any, payable by him thereon, it being understood that
      the economic equivalent of a benefit foregone shall be deemed the average
      cost in the State of New York that would be incurred by the Executive in
      obtaining such benefit himself on an individual basis, and payment of such
      after-tax economic benefit shall be made quarterly in advance; and

                  (vi) all Options shall become immediately exercisable.

The Company's obligation to make the payments provided for in this Agreement and
otherwise to perform its obligations hereunder shall not be affected by any
setoff, counterclaim, recoupment, defense or other claim, right or action which
the Company and/or any of its affiliates may have against the Executive. In no
event shall the Executive be obligated to seek other employment or take any
other action by way of mitigation of the amounts payable to the Executive under
any of the provisions of this Agreement and such amounts shall not be reduced
whether or not the Executive obtains other employment.

      7. Disability; Death

            In the event the Executive shall be unable to perform his duties
hereunder by virtue of illness or physical or mental incapacity or disability
(from any cause or causes whatsoever) in substantially the manner and to the
extent required hereunder prior to the commencement of such disability (all such
causes being herein referred to as "Disability") and the Executive shall fail to
perform such duties for 150 consecutive days, the Company shall have the right
to terminate the Executive's employment hereunder as at the end of any calendar
month during the continuance of such Disability upon at least 90 days' prior
written notice to him. In the event of the Executive's death, the Date of
Termination shall be ninety days from the date of such death.

      8. Covenants Regarding Non-Solicitation and Confidential Information

            (a) The Executive agrees that it is reasonable and necessary for the
protection of the confidential information, goodwill and business of the Company
that the Executive agrees that during the Term and for a one year thereafter he
shall not render any services to, or engage in any business in the New York
metropolitan area, which is engaged in the business of the same nature as or
competitive with the Company; provided, however, that nothing contained in this
paragraph shall be deemed to prevent the undersigned from owing less than 5% of
the shares of any publicly held corporation engaged in any such business.
Notwithstanding anything to the contrary contained in this Agreement, this
paragraph 8(a) shall be null and void and have no force or effect in the event
that the Executive's employment is terminated by the Company for any reason
other than for Cause, the Executive's death or Disability, or pursuant to a
Notice of Termination; or the Executive's employment is terminated by the
Executive for Good Reason; or the Company breaches any of its obligations to
make any payments or provide any benefits under paragraph 6(d) above.

            (b) In the course of the Executive's employment with the Company he
will acquire and have access to confidential or proprietary information about
the Company and/or its clients, including but not limited to, trade secrets,
financial information and records, computer software programs, contracts between
the Company and its clients, marketing and/or creative policies and ideas,
methods of operations, and financial or business projections of the Company. The
foregoing shall be collectively referred to as "confidential information". The
Executive is aware that the confidential information is not readily available to
the public and accordingly, the Executive also agrees that he will not at any
time disclose to anyone any confidential information, or utilize such
confidential information for his own benefit, or for the benefit of third
parties without the prior written consent of the Company. The term "confidential
information" does not include information which (i) becomes generally available
to the public other than by breach of this provision, (ii) is already in the
possession of the Executive as of the date hereof or (iii) the Executive learns
from a third party who is not under an obligation of confidence to the Company
or a client of the Company. In the event that the Executive becomes legally
required to disclose any confidential information, he will be permitted to
furnish only that portion of the confidential information which he is legally
required to disclose and, at the Company's expense, will cooperate with the
efforts of the Company to obtain a protective order or other reliable assurance
that confidential treatment will be accorded the confidential information.


                                       8
<PAGE>

      9. Indemnification

            (a) The Company agrees that if the Executive is made a party, or is
threatened to be made a party, to any action, suit or proceeding, whether civil,
criminal, administrative or investigative (a "Proceeding"), by reason of the
fact that he is or was a director, officer or employee of the Company and/or one
of its subsidiaries or is or was serving at the request of the Company as a
director, officer, member, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether or not the basis of such Proceeding
is the Executive's alleged action in an official capacity while serving as a
director, officer, member, employee or agent, the Executive shall be indemnified
and held harmless by the Company to the fullest extent permitted or authorized
by the Company's certificate of incorporation or by-laws or, if greater, by the
laws of the State of New York, against all cost, expense, liability and loss
(including, without limitation, attorney's fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid or to be paid in settlement) reasonably
incurred or suffered by the Executive in connection therewith, and such
indemnification shall continue as to the Executive even if he has ceased to be a
director, member, employee or agent of the Company or other entity and shall
inure to the benefit of the Executive's heirs, executors and administrators. The
Company shall advance to the Executive all reasonable costs and expenses
incurred by him in connection with a Proceeding within 20 days after receipt by
the Company of a written request for such advance. Such request shall include an
undertaking by the Executive to repay the amount of such advance if it shall
ultimately be determined that he is not entitled to be indemnified against such
costs and expenses.

            (b) Neither the failure of the Company (including the Board,
independent legal counsel or stockholders) to have made a determination prior to
the commencement of any proceeding concerning payment of amounts claimed by the
Executive under paragraph 9(a) above that indemnification of the Executive is
proper because he has met the applicable standard of conduct, nor a
determination by the Company (including the Board, independent legal counsel or
stockholders) that the Executive has not met such applicable standard of
conduct, shall create a presumption that the Executive has not met the
applicable standard of conduct.

      10. Enforceability

            The failure of any party at any time to require performance by
another party of any provision hereunder shall in no way affect the right of
that party thereafter to enforce the same, nor shall it affect any other party's
right to enforce the same, or to enforce any of the other provisions in this
Agreement; nor shall the waiver by any party of the breach of any provision
hereof be taken or held to be a waiver of any subsequent breach of such
provision or as a waiver of the provision itself.

      11. Assignability; Binding Nature

            This Agreement shall be binding upon and inure to the benefit of the
parties and their respective successors, heirs (in the case of the Executive)
and assigns. No rights or


                                       9
<PAGE>

obligations of the Company under this Agreement may be assigned or transferred
by the Company except that such rights or obligations may be assigned or
transferred pursuant to a merger or consolidation in which the Company is not
the continuing entity, or the sale or liquidation of all or substantially all of
the assets of the Company, provided that the assignee or transferee is the
successor to all or substantially all of the assets of the Company and such
assignee or transferee assumes the liabilities, obligations and duties of the
Company, as contained in this Agreement, either contractually or as a matter of
law. The Company further agrees that, in the event of a sale of assets or
liquidation as described in the preceding sentence, it shall take whatever
action it legally can in order to cause such assignee or transferee to expressly
assume the liabilities, obligations and duties of the Company hereunder. No
rights or obligations of the Executive under this Agreement may be assigned or
transferred by the Executive other than his rights to compensation and benefits,
which may be transferred only by will or operation of law, or as provided in
paragraph 12 below.


                                       10
<PAGE>

      12. Beneficiaries/References

            The Executive shall be entitled to select (and change, to the extent
permitted under any applicable law) a beneficiary or beneficiaries to receive
any compensation or benefit payable hereunder following the Executive's death by
giving the Company written notice therefor. In the event of the Executive's
death or a judicial determination of his incompetence, reference in this
Agreement to the Executive shall be deemed, where appropriate, to refer to his
beneficiary, estate or other legal representative.

      13. Modification

            This Agreement may not be orally canceled, changed, modified or
amended, and no cancellation, change, modification or amendment shall be
effective or binding, unless in writing and signed by the parties to this
Agreement.

      14. Severability; Survival

            In the event any provision or portion of this Agreement is
determined to be invalid or unenforceable for any reason, in whole or in part,
the remaining provisions of this Agreement shall nevertheless be binding upon
the parties with the same effect as though the invalid or unenforceable part had
been severed and deleted. The respective rights and obligations of the parties
hereunder shall survive the termination of the Executive's employment to the
extent necessary to the intended preservation of such rights and obligations.

      15. Notice

            Any notice, request, instruction or other document to be given
hereunder by any party hereto to another party shall be in writing and shall be
deemed effective (a) upon personal delivery, if delivered by hand, or (b) three

                                                 Annex I to Employment Agreement

      For purposes of this Agreement, a "Change in Control" shall mean the
occurrence of any one of the following events:

                  (i) The acquisition, after the effective date of the Option
      Plan, by an individual, entity or group (within the meaning of Section
      13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended
      (the "Exchange Act")) of beneficial ownership (within the meaning of Rule
      l3d-3 promulgated under the Exchange Act) of 50% or more of either (a) the
      shares of the voting common stock of the Company (the "Common Stock"), or
      (b) the combined voting power of the voting securities of the Company
      entitled to vote generally in the election of directors (the "Voting
      Securities"); provided, however, that the following acquisitions shall not
      constitute a Change of Control: (x) any acquisition by any employee
      benefit plan (or related trust) sponsored or maintained by the Company or
      any subsidiary, (y) any acquisition by any underwriter in connection with
      any firm commitment underwriting of securities to be issued by the
      Company, or (z) any acquisition by any corporation or any other entity if,
      immediately following such acquisition, more than 50% of the then
      outstanding shares of common stock or common ownership interests and the
      combined voting power of the then outstanding voting securities of such
      corporation or common ownership interests of such other entity (entitled
      to vote generally in the election of directors or other managers), is
      beneficially owned, directly or indirectly, by all or substantially all of
      the individuals and entities who, immediately prior to such acquisition,
      were the beneficial owners of the Common Stock and the Voting Securities
      in substantially the same proportions, respectively, as their ownership,
      immediately prior to such acquisition, of the Common Stock and Voting
      Securities; or

                  (ii) Individuals who, as of the effective date of the Option
      Plan, constitute the Board (the "Incumbent Board") cease thereafter for
      any reason to constitute at least a majority of the Board; provided,
      however, that any individual becoming a director subsequent to the
      effective date of the Option Plan whose election, or nomination for
      election by the Company's shareholders, was approved by at least
      two-thirds of the directors then serving and comprising the Incumbent
      Board shall be considered as though such individual were a member of the
      Incumbent Board, but excluding, for this purpose, any such individual
      whose initial assumption of office occurs as a result of either an actual
      or threatened election contest (as such terms are used in Rule 14a- 11 of
      Regulation 14A promulgated under the Exchange Act) or other actual or
      threatened solicitation of proxies or consents; or

                  (iii) Approval by the shareholders of the Company of, or the
      occurrence of, a reorganization, merger or consolidation, other than a
      reorganization, merger or

<PAGE>

      consolidation with respect to which all or substantially all of the
      individuals and entities who were the beneficial owners, immediately prior
      to such reorganization, merger or consolidation, of the Common Stock and
      Voting Securities beneficially own, directly or indirectly, immediately
      after such reorganization, merger or consolidation more than 50% of the
      then outstanding common stock or common ownership interests and voting
      securities or voting ownership interests (entitled to vote generally in
      the election of directors or other managers) of the corporation or other
      entity resulting from such reorganization, merger or consolidation in
      substantially the same proportions as their respective ownership,
      immediately prior to such reorganization, merger or consolidation, of the
      Common Stock and the Voting Securities; or

                  (iv) Approval by the shareholders of the Company of, or the
      occurrence of, (a) a complete liquidation or substantial dissolution of
      the Company, or (b) the sale or other disposition of all or substantially
      all of the assets of the Company, other than (i) to a subsidiary,
      wholly-owned, directly or indirectly, by the Company, or (ii) pursuant to
      a transaction with respect to which all or substantially all of the
      individuals and entities who were the beneficial owners, immediately prior
      to such transaction, of the Common Stock and the Voting Securities
      beneficially own, directly or indirectly, immediately after such
      transaction, more than 50% of the then outstanding common stock or common
      ownership interests and voting securities or voting ownership interests
      (entitled to vote generally in the election of directors or other
      managers) of the corporation or other business entity acquiring such
      assets in substantially the same proportions as their respective
      ownership, immediately prior to such transaction, of the Common Stock and
      the Voting Securities; or

                  (v) The occurrence of any event (not covered by clauses (i)
      through (iv) above) which would be required to be reported by the Company
      in response to Items 1 or 2 of Form 8-K under the Exchange Act.
