for a period of six months subsequent to the termination or expiration of such
employment with the Company and (ii) related to the business of the Company,
shall be disclosed in writing promptly to the Company and shall be the sole and
exclusive property of the Company.  An invention, idea, process, program,
software, or design including an improvement) shall be deemed related to the
business of the Company if (a) it was made with the Company's equipment,
supplies, facilities, or Confidential Information, (b) results from work
performed by the Employee for the Company, or (c) pertains to the current
business or demonstrably anticipated research or development work of the
Company.  The Employee shall cooperate with the Company and its attorneys in the
preparation of patent and copyright applications for such developments and, upon
request, shall promptly assign all such inventions, ideas, processes, and
designs to the Company.  The decision to file for patent or copyright protection
or to maintain such development as a trade secret shall be in the sole
discretion of the Company, and the Employee shall be bound by such decision.

all inventions, ideas, processes, and designs, if any, patented or unpatented,
copyrighted or non-copyrighted, including a brief description, which he made or

excluded from the scope of this Agreement.

     12.  Indebtedness.  If, during the course of the Employee's employment
          ------------
under this Agreement, the Employee becomes indebted to the Company for any
reason, the Company may, if it so elects, set off any sum due to the Company
from the Employee and collect any remaining balance from the Employee.

     13.  Assignability.  The rights and obligations of the Company under this
          -------------
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Company, provided that such successor or assign shall acquire all
or substantially all of the securities (via merger or otherwise) or assets and
business of the Company.  The Employee's obligations hereunder may not be
assigned or alienated and any attempt to do so by the Employee will be void.

     14.  Severability.
          ------------

          (a) The Employee expressly agrees that the character, duration and
geographical scope of the non-competition provisions set forth in this Agreement
are reasonable in light of the circumstances as they exist on the date hereof.
Should a decision, however, be made at a later date by a court of competent
jurisdiction that the character, duration or geographical scope of such
provisions is unreasonable, then it is the intention and the agreement of the
Employee and the Company that this Agreement shall be construed by the court in
such a manner as to impose only those restrictions on the Employee's conduct
that are reasonable in the light of the circumstances and as are necessary to
assure to the Company the benefits of this Agreement.  If, in any judicial
proceeding, a court shall refuse to enforce all of the separate covenants deemed
included herein because taken together they are more extensive than

                                       8
<PAGE>

necessary to assure to the Company the intended benefits of this Agreement, it
is expressly understood and agreed by the parties hereto that the provisions of
this Agreement that, if eliminated, would permit the remaining separate
provisions to be enforced in such proceeding shall be deemed eliminated, for the
purposes of such proceeding, from this Agreement.

          (b)  If any provision of this Agreement otherwise is deemed to be
invalid or unenforceable or is prohibited by the laws of the state or
jurisdiction where it is to be performed, this Agreement shall be considered
divisible as to such provision and such provision shall be inoperative in such
state or jurisdiction and shall not be part of the consideration moving from
either of the parties to the other.  The remaining provisions of this Agreement
shall be valid and binding and of like effect as though such provision were not
included.

     15.  Notices and Addresses.  All notices, offers, acceptance and any other
          ---------------------

                           SFBC INTERNATIONAL, INC.

I.   Section 4 is hereby deleted and replaced with the following:

     4.   Eligible Employees and Others.
          -----------------------------

          (a)  ISOs may be granted to any employee of the Company or any Related
     Corporation.  Those officers and directors of the Company who are not
     employees may not be granted ISOs under the Plan unless they are employees
     of the Company or any Related Corporation.  Subject to compliance with Rule
     16b-3 and other applicable securities laws, Non-Qualified Options may be
     granted to any director (whether or not an employee), officer, employee or
     consultant of the Company or any Related Corporation.  The Committee may
     take into consideration a recipient's individual circumstances in
     determining whether to grant an ISO or a Non-Qualified Option.  Granting of
     any Option to any individual or entity shall neither entitle that
     individual or entity to, nor disqualify him from participation in any other
     grant.

          (b)  All directors of the Company who are not employees of the Company
     or Related Corporations shall automatically receive grants of 30,000 Non-
     Qualified Options (i) upon election or appointment to the Board if not a
     member of the Board at the time this Plan is adopted by the Board; (ii)
     after all Options previously granted have vested.  In addition, existing
     non-employee directors as of January 11, 2001, shall receive an additional
     grant of 15,000 Non-Qualified Options in order to equalize treatment of
     non-employee directors.

               (1)  The exercise price of all Options shall be fair market value
          on the date of grant as defined by Section 7.

               (2)  The Options shall vest in six equal increments of 5,000
          Options per director on June 30 and December 31 of each year provided
          that the director is still serving as a director of the Company.
          Provided, however, that 7,500 Non-Qualified Options issued to existing
          -----------------
          non-employee directors as of January 11, 2001 shall immediately vest.
          To the extent that any Options which have not been exercised do not
          vest, the Options shall lapse.

          (c)  All Options shall be exercisable for a period of 10 years from
     the date of grant, except where a shorter period is required by the Code
     for certain ISOs or where the board or committee selects a shorter period
     at the time of any discretionary grant.
