          (vi) "Registrable Securities" shall mean the Shares and any shares of
     common stock of the Company issued as a dividend or other distribution with
     respect to or in replacement of Shares; provided, however, that such

statement (the "Registration Statement") with the SEC and use its reasonable
best efforts to effect the registration, qualifications or compliances
(including, without limitation, the execution of any required undertaking to
file post-effective amendments, appropriate qualifications or exemptions under

     the Company determines to obtain, continuously effective until at least the
     second anniversary of the Closing Date or until the Holders have completed
     the distribution described in the registration statement relating thereto,
     whichever first occurs. The period of time during which the Company is
     required hereunder to keep the Registration Statement effective is referred
     to herein as "the Registration Period." Notwithstanding the foregoing at
     the Company's election, the Company may cease to keep such registration,
     qualification or compliance effective with respect to any Registrable
     Securities and the registration rights of a Holder shall expire, at such
     time as the Holder may sell under Rule 144 under the Securities Act (or
     other exemption from registration acceptable to the Company) in a
     three-month period all Registrable Securities then held by such Holder;

                                       7
<PAGE>

          (ii) advise the Holders:

               (A) when the Registration Statement or any amendment thereto has
          been filed with the SEC and when the Registration Statement or any
          post-effective amendment thereto has become effective;

               (B) of any request by the SEC for amendments or supplements to
          the Registration Statement or the prospectus included therein or for
          additional information;

               (C) of the issuance by the SEC of any stop order suspending the
          effectiveness of the Registration Statement or the initiation of any
          proceeding for such purpose;

               (D) of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the Shares included
          therein for sale in any jurisdiction or the initiation or threatening
          of any proceeding for such purpose; and

               (E) of the happening of any event that requires the making of any
          changes in the Registration Statement or the prospectus so that, as of
          such date, the statements therein are not misleading and do not omit
          to state a material fact required to be stated therein or necessary to
          make the statements therein (in the case of the prospectus, in the
          light of the circumstances under which they were made) not misleading;

          (iii) make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of any Registration Statement at the
     earliest possible time;

          (iv) during the Registration Period deliver to each Holder, without
     charge, as many copies of the prospectus included in such Registration
     Statement and any amendment or supplement thereto as such Holder may
     reasonably request; and the Company consents to the use, consistent with
     the provisions hereof, of the prospectus or any amendment or supplement
     thereto by each of the selling Holders of Registrable Securities in
     connection with the offering and sale of the Registrable Securities covered
     by the prospectus or any amendment or supplement thereto;

          (v) prior to any public offering of the Registrable Securities
     pursuant to any Registration Statement, register or qualify or obtain an

                                       8
<PAGE>

     exemption for offer and sale under the securities or blue sky laws of such
     jurisdictions as any such Holders reasonably request in writing, provided
     that the Company shall not for any such purpose be required to qualify
     generally to transact business as a foreign corporation in any jurisdiction
     where it is not so qualified or to consent to general service of process in
     any such jurisdiction, and do any and all other acts or things reasonably
     necessary or advisable to enable the offer and sale in such jurisdictions
     of the Registrable Securities covered by such Registration Statement;

          (vi) cooperate with the Holders to facilitate the timely preparation
     and delivery of certificates representing Registrable Securities to be sold
     pursuant to any Registration Statement free of any restrictive legends to
     the extent not required at such time and in such denomination and
     registered in such names as Holders may request at least three business
     days prior to sales of Registrable Securities pursuant to such Registration
     Statement; and

          (vii) upon the occurrence of any event contemplated by Section
     11(d)(ii)(E) above, the Company shall promptly prepare a post-effective
     amendment to the Registration Statement or a supplement to the related
     prospectus, or file any other required document so that, as thereafter
     delivered to purchasers of the Registrable Securities included therein not
     misleading, the prospectus will not include any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein not misleading in the light of the circumstances under
     which they were made.

     (e) The Holders shall have no right to take any action to restrain, enjoin
or otherwise delay any registration pursuant to Section 11(b) hereof as a result
of any controversy that may arise with respect to the interpretation or
implementation of this Subscription Agreement.

     (f) (i) To the extent permitted by law, the Company will indemnify each
Holder, each underwriter of the Registrable Securities and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which any registration, qualification or compliance has been
effected pursuant to this Subscription Agreement, against losses, damages and
liabilities (or action in respect thereof), including any of the incurred in
settlement of any litigation, commenced or threatened (subject to Section
11(f)(iii) below), arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any Registration Statement,
prospectus or offering circular, or any amendment or supplement thereof,
incident to any such registration, qualification or compliance, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
light of the circumstances in

                                       9
<PAGE>

which they were made, and will reimburse each Holder, each underwriter of the
Registrable Securities and each person controlling such Holder, for reasonable
legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action as
incurred; provided that the Company will not be liable in any such case to the
extent that any untrue statement or omission or allegation thereof is made in
reliance upon and in conformity with written information furnished to the
Company by or on behalf of such Holder and stated to be specifically for use in
preparation of such registration statement, prospectus or offering circular;
further provided that the indemnity contained in this Section 11(f)(i) shall not
apply to amounts paid in settlement of any such claim, loss, damages, liability,
action or proceeding if such settlement is effected without the consent of the
Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case where the claim, loss, damage or liability
arises out of or is related to the failure of the Holder to comply with the
covenants and agreements contained in this Agreement with respect to the sales
of Registrable Securities, and except that the foregoing indemnity agreement is
subject to the conditions that insofar as it relates to (A) any such untrue
statement or alleged untrue statement or omission or alleged omission made in
the preliminary prospectus but eliminated or remedied in the amended prospectus
filed with the SEC pursuant to Rule 424(b) or in the prospectus subject to
completion and term sheet under Rule 434 of the Securities Act, which together
meet the requirements of Section 10(a) of the Securities Act (the "Final
Prospectus"), such indemnity agreement shall not inure to the benefit of any
such Holder, any such underwriter or any such controlling person, if a copy of
the Final Prospectus was not furnished to person or entity asserting the loss,
liability, claim or damage at or prior to the time such furnishing is required
by the Securities Act, and (B) any such untrue statement or alleged untrue
statement or omission or alleged omission based upon information furnished to
the Company by such Holder, such indemnity agreement shall not inure to the
benefit of any such Holder, any such underwriter or any such controlling person;

          (ii) Each Holder will severally, if Registrable Securities held by
     such Holder are included in the securities as to which such registration,
     qualification or compliance is being effected, indemnify the Company, each
     of its directors and officers, each underwriter of the Shares and each
     person who controls the Company within the meaning of Section 15 of the
     Securities Act, against all claims, losses, damages and liabilities (or
     actions in respect thereof), including any of the foregoing incurred in
     settlement of any litigation, commenced or threatened (subject to Section
     11(f)(iii) below), arising out of or based on any untrue statement (or
     alleged untrue statement) of a material fact contained in any registration
     statement, prospectus or offering circular, or any amendment or supplement
     thereof, incident to any such registration, qualification or compliance, or
     based on any omission (or alleged omission) to state therein a material
     fact

                                       10
<PAGE>

     required to be stated therein or necessary to make the statements therein
     not misleading, in light of the circumstances in which they were made, and
     will reimburse the Company, such directors and officers, each underwriter
     of the Shares and each person controlling the Company for reasonable legal
     and any other expenses reasonably incurred in connection with investigating
     or defending any such claim, loss, damage, liability or action as incurred,
     in each case to the extent, but only to the extent, that such untrue
     statement or omission or allegation thereof is made in reliance upon and in
     conformity with written information furnished to the Company by or on
     behalf of the Holder and stated to be specifically for use in preparation
     of such registration statement, prospectus or offering circular; provided
     that the indemnity shall not apply to the extent that such claim, loss,
     damage or liability results from the fact that a current copy of the
     prospectus that was made available to the Holder was not sent or given to
     the person asserting any such claim, loss, damage or liability at or prior
     to the written confirmation of the sale of the Registrable Securities
     confirmed to such person if such current copy of the prospectus would have
     cured the defect giving rise to such loss, claim, damage or liability.
     Notwithstanding the foregoing, in no event shall a Holder be liable for any
     such claims, losses, damages or liabilities in excess of the proceeds
     received by such Holder in the offering, except in the event of fraud by
     such Holder;

          (iii) Each party entitled to indemnification under this Section 11(f)
     (the "Indemnified Party") shall give notice to the party required to
     provide indemnification (the "Indemnifying Party") promptly after such
     Indemnified Party has actual knowledge of any claim as to which indemnity
     may be sought, and shall permit the Indemnifying Party to assume the
     defense of any such claim or any litigation resulting therefrom, provided
     that counsel for the Indemnifying Party, who shall conduct the defense of
     such claim or litigation, shall be approved by the Indemnified Party (whose
     approval shall not unreasonably be withheld), and the Indemnified Party may
     participate in such defense at such Indemnified Party's expense, and
     provided further that the failure of any Indemnified Party to give notice
     as provided herein shall not relieve the Indemnifying Party of its
     obligations under this Subscription Agreement, unless such failure is
     prejudicial to the Indemnifying Party in defending such claim or
     litigation. An Indemnifying Party shall not be liable for any settlement of
     an action or claim effected without its written consent (which consent will
     not be unreasonably withheld);

          (iv) If the indemnification provided for in this Section 11(f) is held
     by a court of competent jurisdiction to be unavailable to an Indemnified
     Party with respect to any loss, liability, claim, damage or expense
     referred to therein, then the Indemnifying Party, in lieu of indemnifying
     such Indemnified Party thereunder, shall contribute to the amount paid or
     payable by

                                       11
<PAGE>

     such Indemnified Party as a result of such loss, liability, claim, damage
     or expense 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, liability, claim, damage or expense 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 the omission to state 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.

     (g) (i) Each Holder agrees that, upon receipt of any notice from the
Company of the happening of any event requiring the preparation of a supplement
or amendment to a prospectus relating to Registrable Securities so that, as
thereafter delivered to the Holders, such prospectus will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, each
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to the Registration Statement contemplated by Section 11(b) until its receipt of
copies of the supplemented or amended prospectus from the Company and, if so
directed by the Company, each Holder shall deliver to the Company all copies,
other than permanent file copies then in such Holder's possession, of the
prospectus covering such Registrable Securities current at the time of receipt
of such notice;

          (ii) Each Holder agrees to suspend, upon request of the Company, any
     disposition of Registrable Securities pursuant to the Registration
     Statement and prospectus contemplated by Section 11(b) during (A) any
     period not to exceed two 30-day periods within any one 12-month period the
     Company requires in connection with a primary underwritten offering of
     equity securities and (B) any period, not to exceed one 30-day period per
     circumstance or development, when the Company determines in good faith that
     offers and sales pursuant thereto should not be made by reason of the
     presence of material undisclosed circumstances or developments with respect
     to which the disclosure that would be required in such a prospectus is
     premature, would have an adverse effect on the Company or is otherwise
     inadvisable;

          (iii) As a condition to the inclusion of its Registrable Securities,
     each Holder shall furnish to the Company such information regarding such
     Holder and the distribution proposed by such Holder as the Company may
     request in writing or as shall be required in connection with any
     registration, qualification or compliance referred to in this Section 11;

                                       12
<PAGE>

          (iv) Each Holder hereby covenants with the Company (A) not to make any
     sale of the Registrable Securities without effectively causing the
     prospectus delivery requirements under the Securities Act to be satisfied,
     and (B) if such Registrable Securities are to be sold by any method or in
     any transaction other than on a national securities exchange, in the
     over-the-counter market, in privately negotiated transactions, or in a
     combination of such methods, to notify the Company at least five business
     days prior to the date on which the Holder first offers to sell any such
     Shares;

          (v) Each Holder acknowledges and agrees that the Registrable
     Securities sold pursuant to a Registration Statement are not transferable
     on the books of the Company unless the stock certificate submitted to the
     transfer agent evidencing such Registrable Securities is accompanied by a
     certificate reasonably satisfactory to the Company to the effect that (A)
     the Registrable Securities have been sold in accordance with such
     Registration Statement and (B) the requirement of delivering a current
     prospectus has been satisfied;

          (vi) Each Holder agrees not to take any action with respect to any
     distribution deemed to be made pursuant to such Registration Statement,
     that constitutes a violation of Regulation M under the Exchange Act or any
     other applicable rule, regulation or law;

          (vii) At the end of the period during which the Company is obligated
     to keep the Registration Statement current and effective as described
     above, the Holders of Registrable Securities included in the Registration
     Statement shall discontinue sales of shares pursuant to such Registration
     Statement upon receipt of notice from the Company of its intention to
     remove from registration the shares covered by such Registration Statement
     which remain unsold, and such Holders shall notify the Company of the
     number of shares registered which remain unsold immediately upon receipt of
     such notice from the Company.

     (h) With a view to making available to the Holders the benefits of certain
rules and regulations of the SEC which at any time permit the sale of the
Registrable Securities to the public without registration, the Company agrees to
use its reasonable best efforts to:

          (i) make and keep public information available, as those terms are
     understood and defined in Rule 144 under the Securities Act, at all times;

          (ii) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Exchange Act; and

                                       13
<PAGE>

          (iii) so long as a Holder owns any unregistered Registrable
     Securities, furnish to such Holder upon any reasonable request a written
     statement by the Company as to its compliance with Rule 144 under the
     Securities Act, and of the Exchange Act, a copy of the most recent annual
     or quarterly report of the Company, and such other reports and documents of
     the Company as such Holder may reasonably request in availing itself of any
     rule or regulation of the SEC allowing a Holder to sell any such securities
     without registration.

     (i) The rights to cause the Company to register Registrable Securities
granted to the Holders by the Company under Section 11(a) may be assigned in
full by a Holder, provided that such transfer may otherwise be effected in
accordance with applicable securities laws; (ii) such Holder gives prior written
notice to the Company; and (iii) such transferee agrees to comply with the terms
and provisions of this Subscription Agreement, and such transfer is otherwise in
compliance with this Subscription Agreement. Except as specifically permitted by
this Section 11(i), the rights of a Holder with respect to Registrable
Securities as set out herein shall not be transferable to any other Person, and
any attempted transfer shall cause all rights of such Holder therein to be
forfeited.

     (j) With the written consent of the Company and the Holders holding at
least a majority of the Registrable Securities that are then outstanding, any
provision of this Section 11 may be waived (either generally or in a particular
instance, either retroactively or prospectively and either for a specified
period of time or indefinitely) or amended. Upon the effectuation of each such
waiver or amendment, the Company shall promptly give written notice thereof to
the Holders, if any, who have not previously received notice thereof or
consented thereto in writing.

     12. Acknowledgment. The undersigned acknowledges that the undersigned has
carefully read and fully understands this Subscription Agreement and its
representations.

     13. Governing Law. This Subscription Agreement shall be governed by and
construed in accordance with the laws of the State of New York with the
exception of the choice of law provisions thereof.

     14. Counterparts. This Subscription Agreement shall be executed through the
use of separate signature pages or in any number of counterparts, and each of
such counterparts shall, for all purposes, constitute one agreement binding on
all parties.

                                       16EXHIBIT 10.7

                        AMENDMENT TO EMPLOYMENT AGREEMENT

     This Amendment to Employment  Agreement (the "Amendment"),  dated as of the
28th day of March,  2000 by and  between  COMFORCE  Corporation  ("COMFORCE")  a
Delaware  corporation,   and  COMFORCE  Operating,   Inc.  ("COI"),  a  Delaware
corporation that is wholly-owned by COMFORCE  (COMFORCE and COI are collectively
referred to as the  "Employer"),  and John  Fanning,  a resident of the State of
Florida ("Employee").

                                    RECITALS:

     A. The  parties  entered  into an  Employment  Agreement  (the  "Employment
Agreement")  dated as of January 1, 1999 pursuant to which  Employer  formalized
the terms upon which Employee is employed by Employer.

     B. Prior to August 1, 1999,  Employer and  Employee  agreed to revisions to
amend the terms of the Employment  Agreement  effective as of August 1, 1999 and
since  that  date  have  acted  in  accordance  with  the  provisions  that  are
memorialized hereunder.

     NOW, THEREFORE,  in consideration of the promises and mutual obligations of
the parties contained herein, and for other valuable consideration,  the receipt
and  sufficiency of which are hereby  acknowledged,  the parties hereto agree as
follows:

     1.  Section  4(a) of the  Employment  Agreement  is hereby  amended  in its
entirety to read as follows:

          (a) Base Salary.  During the Term of  Employment,  as Employee's  base
     compensation for all services to be performed hereunder, Employer shall pay
     Employee an annual salary of One Hundred Thousand  Dollars  ($100,000) (the
     "Base Salary"), payable in accordance with the Employer's payroll practices
     for its officers.  The Base Salary shall be increased  from time to time at
     the  discretion of the Board of Directors or any committee  thereof  having
     authority over Employee's  compensation to account for material  changes of
     circumstances of the Employer or of the  responsibilities of Employee,  and
     may be  increased by the Board or such  committee  from time to time in its
     discretion for any other reason whatsoever.

     2. The first  sentence  of  Section  4(e) of the  Employment  Agreement  is
amended in its entirety to read as follows:

     In addition to Employee's  compensation as provided herein,  Employer shall
     pay incentive compensation for each year (which shall commence on January 1
     and end on December 31) during the Term of Employment in an amount equal to
     10% of the Employer's  consolidated  pre-tax  operating income in excess of
     $2,000,000,  but not in excess  of  $4,000,000,  plus 5% of such  income in
     excess of $4,000,000,  but not in excess of $10,000,000,  plus 3.5% of such
     income in excess of $10,000,000.  To the extent  incentive  compensation is
     calculated  based on consolidated  pre-tax  operating  income for a partial
     year, the thresholds set forth above shall be adjusted by multiplying  them
     by the number of days of the partial year and dividing  that product by 365
     and  then   calculating   the  incentive   compensation   based  on  actual
     consolidated  pre-tax  operating  income for the  partial  year.  By way of
     example, if incentive  compensation were calculated for a short period from
     January 1 to June 30 based on  consolidated  pre-tax  operating  income for
     that  period of  $6,000,000,  the  thresholds  would be reduced to $991,781
     ($2,000,000 x 181/365),  $1,983,562  ($4,000,000 x 181/365) and  $4,958,904
     ($10,000,000  x 181/365) and the incentive  compensation  would be equal to
     $284,383 (10% x ($1,983,562 - $990,781) + (5% x ($4,958,904 - $1,983,562) +
     (3.5% x ($6,000,000 - $4,958,904). Notwithstanding the foregoing, for 1999,
     incentive compensation shall not be calculated for a partial year and shall
     for that year only,  notwithstanding  the effective date of this Amendment,
     be calculated  based on the consolidated  pre-tax  operating income for the
     entire calendar year.

                                      E-3

     3. Section  7(d)(i) of the  Employment  Agreement is hereby  amended in its
entirety to read as follows:

     (i) The Employer will pay to Employee immediately after such termination of
     employment a lump-sum  cash payment  equal to 300% of the  aggregate of (A)
     the greater of (1) the sum of (x) his then-current  annual base salary (or,
     if his base  salary  has been  reduced  at any time  after  the  Change  of
     Control,  his base salary in effect prior to the  reduction),  plus (y) the
     highest amount of cash bonus and incentive compensation paid to Employee in
     any one (1) year during the three (3) calendar years  immediately  prior to
     the Change of Control or (2) the Original  Compensation  Amount, as defined
     herein,  (B) the annual cost to the  Employer of any  benefits,  other than
     those provided for by Section 4(d), then provided to Employee,  and (C) the
     amount  contributed  by the  Employer  on  behalf of the  Employee  for the
     calendar  year  ending  immediately  prior  to  the  termination,   without
     duplication  of  amounts  accounted  for under  clauses  (A) or (B) of this
     subsection,  to any pension,  deferred compensation,  retirement or similar
     plan of the  Employer.  For purposes  hereof,  the  "Original  Compensation
     Amount"  shall  mean  the sum of (x)  Three  Hundred  Eighty-Five  Thousand
     Dollars  ($385,000) and (y) an amount equal to 5% of the Employer's highest
     consolidated  pre-tax  operating income during the three (3) calendar years
     immediately prior to the Change of Control to the extent it is in excess of
     $2,500,000, but not in excess of $3,000,000, plus 3.5% of such consolidated
     pre-tax operating income to the extent it is in excess of $3,000,000.

     4. All other  provisions of the Employment  Agreement  shall remain in full
force and effect.

                                      E-4

     IN WITNESS WHEREOF, the undersigned have executed this Agreement on the day
and year first above mentioned.
