herein, the Employee agrees to be bound by the terms of the non-competition
agreement contained in any written employment agreement of Employee in effect at
such time, or if there is no such written employment agreement in effect at such
time:

      (a) Until the termination of his employment and for one (1) year
commencing on the date of such termination of employment (the "Effective Date of
Termination"), the Employee, directly or indirectly or, 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 (any of the foregoing, an "Affiliated
Entity") shall not act as an executive officer or provide Services to any entity
which competes with PharmaNet, Inc. or its subsidiaries (collectively,
"PharmaNet"), within any metropolitan area in the United States or elsewhere in
which PharmaNet or the Company or any of its other subsidiaries (collectively,
the "Affiliates"), if applicable, is then engaged in the offer and sale of
competitive Services (as defined below); provided, however, the foregoing
provisions shall not prevent the Employee from accepting employment with an
enterprise engaged in two or more lines of business, one of which is the same or
similar to PharmaNet's business (the "Prohibited Business") if the Employee's
employment is totally unrelated to the Prohibited Business; provided, further,
the foregoing shall not prohibit Employee from owning up to five percent (5%) of
the securities of any publicly-traded enterprise that engages in the Prohibited
Business provided the Employee is not an employee, director, officer, consultant
to such enterprise or otherwise reimbursed for services rendered to such
enterprise. In addition, during the period

<PAGE>

commencing on the Effective Date of Termination and continuing for twelve (12)
months thereafter, the Employee may not, directly or indirectly, including
through any affiliated entity, seek Prohibited Business from any Client (as
defined below) on behalf of any enterprise or business other than PharmaNet,
refer Prohibited Business generated from any Client to any enterprise or
business other than PharmaNet, cause any Client to cancel or reduce any existing
contract for services it may have with PharmaNet or receive commissions based on
sales or otherwise relating to the Prohibited Business from any Client,
enterprise or business other than PharmaNet. For purposes of this Section 4, the
term "Client" means any person, firm, corporation, limited liability company,
partnership, association or other entity (i) to which PharmaNet sold or provided
Services in excess of $100,000 during the 24-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 Client, or (ii)
who or which has been approached by an employee of PharmaNet for the purpose of
soliciting business for PharmaNet and which business was reasonably expected to
generate revenue in excess of $100,000.

      (b) Solicitation of Employees and Certain Others. During the period
commencing on the date of termination of employment and continuing for 12 months
thereafter, the Employee, shall not, directly or indirectly, including through
any Affiliated Entity, solicit, hire, retain, entice, interfere with, or contact
any employee or independent contractor of PharmaNet, or any of its subsidiaries,
for the purpose of hiring them, having another person or entity hire them, the
offering of any employment, the procuring of employment, or causing the Employee
to alter, modify, or terminate, their employment, or other relationship, as the
case may be, with PharmaNet or any of its subsidiaries, nor provide any
assistance, directly or indirectly, regarding any employment offer, agreement,
or relationship, or assistance in the procuring of employment.

      (c) References to PharmaNet in this Section 4 shall include the Company
and all Affiliates.

      5. Termination of Relationship.

            (a) If for any reason, except death or disability as provided below,
the Employee ceases to act as an employee of the Company, all rights granted
hereunder shall terminate effective three months from the date the Employee
ceases to act as an employee, except as otherwise provided for herein.

Options subject to Section 3(c). For the purpose of this Agreement, "Transferee"
shall mean a person to whom such shares are transferred by will or by the laws
of descent and distribution.

            (c) No transfer of the Options by the Employee by will or by the
laws of descent and distribution or pursuant to a qualified domestic relations
order under Section 414(p)(1)(A) of the Code ("QDRO") shall be effective to bind
the Company unless the Company shall have been furnished with written notice
thereof and a copy of the letters testamentary, the court order or such

<PAGE>

other evidence as the Board may deem necessary to establish the authority of the
state and the acceptance by the Transferee or Transferees of the terms and
conditions of the Options.

            (d) If the Employee becomes disabled while employed by the Company
within the meaning of Section 22(e)(3) of the Code, the three month period
referred to in Section 5(a) of this Agreement shall be extended to one year.

      6. Profits on the Sale of Certain Shares; Redemption. If any of the events
specified in Section 3(b) of this Agreement occur within one year from the
Effective Date of Termination (or such longer period required by any written
employment agreement), all profits earned from the sale of the Company's
securities, including the sale of shares of common stock underlying Options,
during the two-year period commencing one year prior to the Effective Date of
Termination shall be forfeited and forthwith paid by the Employee to the
Company. Further, in such event, the Company may at its option redeem shares of
common stock acquired upon exercise of Options. The Company's rights under this
Section 6 do not lapse one year from the Effective Date of Termination but are a
contract right subject to any appropriate statutory limitation period.

notice which shall:

            (a) state the election to exercise the Options, the number of shares

Company, of the right of such person or persons to exercise the Options.

            (d) be accompanied by full payment of the purchase or exercise price
therefor in United States dollars by check.

Company's common stock acquired pursuant to Options granted hereunder can be
publicly sold by the Employee in compliance with the Securities Act of 1933,
subject to effectiveness of a Form S-8 which registration statement the Company
is in the process of filing.

      9. Anti-Dilution Provisions. The Options granted hereunder shall have the
anti-dilution rights set forth in the Plan.

<PAGE>

      10. Necessity to Become Holder of Record. Neither Employee nor his/her
estate or a transferee pursuant to a QDRO, as provided in Section 5(c), shall
have any rights as a stockholder with respect to any shares covered by the
Options until such person shall have become the holder of record of such shares.

or extraordinary, in respect of such shares for which the record date is prior
to the date on which he/she shall become the holder of record thereof.

this Agreement shall restrict the right of the Company to terminate the
relationship of the Employee at any time, with or without cause. The termination
of the relationship of the Employee by the Company, regardless of the reason
therefor, shall have the results provided for in Sections 5 and 6 of this
Agreement.

      12. Conditions to Exercise of Options. In order to enable the Company to
comply with the Securities Act of 1933 (the "Securities Act") and relevant state
law, the Company may require the Employee, his estate, or any Transferee, as a
condition of the exercising of the Options granted hereunder, to give written
assurance satisfactory to the Company that the shares subject to the Options are

distribution of same, and that any subsequent resale of any such shares either
shall be made pursuant to a registration statement under the Securities Act and
applicable state law which has become effective and is current with regard to
the shares being sold, or shall be pursuant to an exemption from registration
under the Securities Act and applicable state law.

      The Options are subject to the requirement that, if at any time the Board
shall determine, in its discretion, that the listing, registration, or
qualification of the shares of common stock subject to the Options upon any
securities exchange or under any state or federal law, or the consent or
