             ----------------------------
the Buyer harmless against and in respect of:

                  (a) two-thirds (2/3) of all obligations and liabilities of the

forth in the Balance Sheet or disclosed in the Disclosure Schedule of this
Agreement of which they are aware or should reasonably be aware;

                  (b) two-thirds (2/3) of any loss, liability or damage suffered
or incurred by the Buyer because of a breach of any obligation of the Company or
Erbe incurred under this Agreement, or because any representation or warranty by
the Company or Erbe contained herein, in any document furnished or required to

             ------------------------------------------

                  (a) Any party claiming a right to indemnification hereunder
(the "Indemnified Party") shall give prompt written notice to the party from
which the indemnification is sought (the "Indemnifying Party") of any claim
against the Indemnified Party which might give rise to a claim by the
Indemnified Party against the Indemnifying Party based on the indemnity
agreement contained in Section 9.3 or Section 9.4 hereof, stating the nature and
basis of the first-mentioned claim and the amount thereof. No failure to give
such notice shall excuse any Indemnifying Party from any obligation hereunder
except to the extent the Indemnifying Party is prejudiced by such failure.

                  (b) The Indemnified Party shall have full responsibility and
authority with respect to the disposition of any action, suit or proceeding
brought against it. In the event any action, suit or proceeding is brought

have liability under the indemnity agreements contained in Section 9.3 or 9.4
hereof, however, the Indemnifying Party shall have the right, without prejudice
to the Indemnified Party's rights under this Agreement, at the Indemnifying
Party's sole expense, to be represented by counsel of its own choosing and with
whom counsel for the Indemnified Party shall confer in connection with the
defense of any such action, suit, or proceeding. The Indemnified Party shall
make available to the Indemnifying Party and its counsel and accountants, all
books 


                                      29

 
and records of the Indemnified Party relating to such action, suit or
proceeding and the parties agree to render to each other such assistance as may
reasonably be requested in order to insure the proper and adequate defense of
any such action, suit or proceeding.

             -------------------------            
contained in this Agreement (a) Erbe shall not be liable for any claim for
indemnification or contribution pursuant to Section 9.3 unless and until the
aggregate amount of indemnifiable losses payable by Erbe in the aggregate equals
or exceeds $100,000, in which event Erbe shall be liable for the excess of the
total amount payable under Section 9.3 over $100,000 and (b) in no event shall
Erbe be liable for aggregate losses under Section 9.3, in excess of the
aggregate amount of consideration received by Erbe hereunder and under the
Contingent Certificate and as a result of any distributions made pursuant to
Section 2.5 hereof.

X.       REGISTRATION RIGHTS
         -------------------

                  (a) COMFORCE promptly, but in any event within thirty (30)
days after each issuance of COMFORCE Stock under the Contingent Certificate,
will prepare and file with the SEC a Registration Statement on Form S-3 or on
such other form as may be required by the SEC (the "Form S-3") for the purpose
of registering under the Securities Act such number of the shares of COMFORCE
Stock received by Erbe under the Contingent Certificate together with any
additional shares of COMFORCE Stock issued as a dividend or other distribution
with respect to, or in exchange for or in replacement of, such shares of
COMFORCE Stock (together, the "Registrable Shares"), as he indicates that he may
wish to sell from time to time in non- underwritten offerings within two years
after the purchase of the shares of COMFORCE Stock as a result of the exercise.
At the option of COMFORCE, the Form S-3 may include shares of COMFORCE Stock
held by other parties. Erbe will supply to COMFORCE such information concerning
himself and his intentions with respect to the sale of the COMFORCE Stock as is
necessary for inclusion in the Form S-3. COMFORCE will use its best efforts to
cause the Form S-3 to become effective as soon as possible after it is filed.

                  (b) COMFORCE will use its best efforts to keep the Form S-3
continuously in effect for a period of up to two years from the date on which it
become effective by means of filing Forms 10-K, 10-Q and 8-K and annual reports
under the Securities Exchange Act of 1934 (the "1934 Act") and/or by amendment
of the Prospectus included in the Form S-3 (the "Prospectus"), or if earlier,
until Erbe has completed the sale of such of the Registrable Shares as Erbe
desires to sell. COMFORCE will advise Erbe if, at any time during such two-year
period, sales by means of the Prospectus must be suspended pending the filing of
additional documents under the 1934 Act and/or amendment of the Prospectus. Erbe
understands that there may be periods of time within such two-year period when
it is in the best interests of Company and its stockholders to defer disclosure
of pending corporate transactions until they have reached a more advanced stage
and that during such periods sales of the Registrable Shares by means of the
Prospectus will have to be suspended.


                                      30

 
                  (c) If the proposed manner of sale of the shares of COMFORCE
Stock shall require that COMFORCE register or qualify such shares for sale under
state securities or blue sky laws, COMFORCE will use its best efforts to effect
such registration or qualification; provided, however, that COMFORCE shall not
be required to qualify generally to do business, subject itself to general
taxation or general consent to service of process in any jurisdiction where it
would not otherwise be required to do so but for this subsection (c).

                  (d) COMFORCE will furnish to Erbe (a) two complete copies of
the Form S-3, with all exhibits, (b) two copies of all documents incorporated by
reference therein, and reasonable quantities of the Prospectus as amended from
time to time.

                  (e) The Company will cause to be furnished to Erbe, upon his
request made not more often than once per quarter, at the time of a disposition
of the Registrable Shares, an opinion of counsel for the Company (which opinion
shall be in form reasonably satisfactory to the Erbe and its counsel) to the
effect that a registration statement covering the offering of such Registrable
Shares has been filed with the SEC under the Securities Act and has been made
effective by order of the SEC, that a prospectus complying as to form with the
requirements of the Securities Act is available for delivery, that no stop order
has been issued by the SEC suspending the effectiveness of such registration
statement and that, to the best of such counsel's knowledge, no proceedings for
the issuance of such a stop order are threatened or contemplated, and that the
securities included in the offering covered by such registration statement have
been registered or qualified, or exempted from such registration or
qualification, under the securities or blue sky laws of each state in which the
Company has been required to register or qualify such Registrable Shares as
contemplated to this Article X.

                  (f) The Company will notify Erbe and its counsel promptly
after the Company receives notice that any registration statement, supplement or
amendment has become effective, any registration statement is required to be
amended or supplemented, or any stop order with respect thereto has been issued.

                  (g) Erbe shall be responsible for notifying brokers through
whom sales of the Registrable Shares are effected by means of the Form S-3 that
such shares have been registered on Form S-3 and for supplying copies of the
Prospectus to such brokers.

                  (h) All expenses incurred by COMFORCE in complying with
subsections (a) through (d) above including, without limiting the generality of
the foregoing, registration and filing fees, transfer agents' fees and expenses,
fees and expenses of complying with state securities or blue sky laws and
expenses of COMFORCE's attorneys and accountants, and printing expense, shall be
paid by COMFORCE; provided, however, that all brokerage fees and commissions and
underwriting discounts and commissions arising from the sale of the Registrable
Shares by Erbe shall be borne by Erbe.


                                      31

 
                  (i) In connection with the registration of any Registrable
Shares under the Securities Act pursuant to this Agreement, COMFORCE shall
indemnify and hold harmless Erbe, any broker or any other person acting on
behalf of Erbe and each other person, if any, who controls any of the foregoing
persons within the meaning of the Securities Act against any losses, claims,
damages or liabilities, joint or several (or actions in respect thereof), to
which any of the foregoing persons may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement contained in the Form S-3, any preliminary prospectus
or final prospectus contained therein or otherwise filed with the SEC, any
amendment or supplement thereto or any document incident to registration or
qualification of any Registrable Shares, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading or,
with respect to any prospectus, necessary to make the statements therein in
light of the circumstances under which they were made not misleading, or any
violation by COMFORCE of the Securities Act or state securities or blue sky laws
applicable to COMFORCE and relating to action or inaction required of COMFORCE
in connection with such registration or qualification under such state
securities or blue sky laws; and shall reimburse Erbe, such broker or such other
persons acting on behalf of Erbe and each such controlling person for any legal
or other expenses reasonably incurred by any of them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that COMFORCE shall not be liable in any such case to the
extent that such loss, claim, damage, liability or action arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in said Form S-3, preliminary prospectus, final
prospectus, amendment, supplement or document incident to registration or
qualification of any Registrable Shares in reliance upon and in conformity with
written information furnished to COMFORCE through an instrument duly executed by
Erbe specifically for use in the preparation thereof.

                  (j) If the indemnification provided for in subsection (i) is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, claim, damage, liability or action referred to
herein, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such loss, claim, damage, liability or action in such proportion
as is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the
statements or omissions which resulted in such loss, claim, damage, liability or
action as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and of the indemnified party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact, or omission or alleged omission of a material
fact, relates to information supplied by the indemnifying party or by the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.


                                      32

 
                  (k) Erbe agrees to execute and deliver from time to time such
customary lock-up letters relating to the COMFORCE Stock as any underwriter
participating in an underwritten offering or proposed underwritten offering of
securities of COMFORCE requires.
