     FIRST SUPPLEMENTAL INDENTURE, dated as of November 29, 2000 (the
"Supplemental Indenture"), between COMFORCE Operating, Inc., a Delaware
corporation (together with its successors as provided for in the Indenture
referred to below, the "Company"), and Wilmington Trust Company, as Trustee (the
"Trustee"), under an Indenture dated as of November 26, 1997 (the "Indenture")
with respect to the 12% Senior Notes due 2007 of the Company (the "Notes").

     Section 9.2(a) of the Indenture provides that, with the consent of the
Holders of at least a majority in outstanding principal amount of the
Securities, voting as a single class, the Company and the Trustee may amend the
Indenture or the Securities, unless such amendment accomplishes any of the
actions enumerated in subsections 1 through 11 of Section 9.2(a). The Company
and the Trustee are executing this Supplemental Indenture to amend Sections 1.1.
and 4.3(b)(i) of the Indenture for the following reasons, none of which affects
any of the actions specified under subsections 1 through 11 of Section 9.2(a):

     (1) to allow the Company the flexibility to use securitization financing
     techniques that may be more cost effective and flexible than current
     financing arrangements (i) by amending the definition of "Asset
     Disposition" in Section 1.1 to exclude permitted Securitizations therefrom
     (see new clause (iii) in the definition), (ii) by adding a definition of
     "Securitization" in Section 1.1 and (iii) by amending Section 4.3(b)(i) to
     include Securitizations within the indebtedness limits;

     (2) through the amendment of the definition of "Consolidated Net Income"
     (see the proviso added to clause (iv)) to make clear that any gain or loss
     realized by the Company upon the repurchase of Notes will be treated as an
     extraordinary gain or loss, and the costs incurred by the Company in
     soliciting consents to amend the Indenture will not be treated as an
     extraordinary loss;

     (3) to limit the aggregate amount of Notes outstanding under the Indenture
     at any time to $110 million rather than the $200 million currently
     permitted by amending Section 2.2(d);

     (4) to permit the Company to increase its borrowing (and securitization of
     assets) (i) by amending Section 4.3(b)(i) to allow credit facility debt up
     to the greater of (x) $75 million at any time outstanding, less the
     aggregate principal amount thereof repaid with the net proceeds of Asset
     Dispositions and (y) 90% of Eligible Accounts Receivable outstanding at any
     time, and (ii) by adding a definition of "Eligible Accounts Receivable" in
     Section 1.1; and

     (5) through the amendment of Section 4.4(a)(i), (i) increasing the
     permitted amount of "public company" expenses payable to the Company's
     parent, COMFORCE Corporation, from $1.25 million to $2.0 million annually,
     and (ii) permitting the Company to pay income tax on forgiveness of
     indebtedness of COMFORCE Corporation in an amount not to exceed $10 million
     cumulatively so as to facilitate the exchange or purchase by COMFORCE
     Corporation of outstanding indebtedness at less than par.

                                  AMENDMENTS

Section 1.01.  Amendment of Section 1.1 of the Indenture.

     A.   The existing definitions of "Asset Disposition" and "Consolidated Net
Income" are hereby amended and restated as follows:

     "Asset Disposition" means any sale, lease, transfer, issuance or other
     disposition (or series of related sales, leases, transfers, issuances or
     dispositions that are part of a common plan) of shares of Capital Stock of
     (or any other equity interests in) a Restricted Subsidiary (other than
     directors' qualifying shares) or of any other property or other assets
     (each referred to for the purposes of this definition as a "disposition")
     by the Company or any of its Restricted Subsidiaries (including any
     disposition by means of a merger, consolidation or similar transaction)
     other than (i) a disposition by a Restricted Subsidiary to the Company or
     by the Company or a Restricted Subsidiary to a Wholly-Owned Subsidiary,
     (ii) a disposition of inventory in the ordinary course of business, (iii) a
     Securitization, to the extent permitted in Section 4.3 (b) (i) herein, (iv)
     a disposition of obsolete or worn out equipment or equipment that is no
     longer useful in the conduct of the business of the Company and its
     Restricted Subsidiaries and that is disposed of in each case in the
     ordinary course of business, (v) dispositions of property for net proceeds
     which, when taken collectively with the net proceeds of any other such
     dispositions under this clause (v) that were consummated since the
     beginning of the calendar year in which such disposition is consummated, do
     not exceed $1.0 million, and (vi) transactions permitted pursuant to
     Section 5.1 of this Indenture. Notwithstanding anything to the contrary
     contained above, a Restricted Payment made in compliance with Section 4.4
     of this Indenture shall not constitute an Asset Disposition except for
     purposes of determinations of the Consolidated Coverage Ratio.

     "Consolidated Net Income" means, for any period, the consolidated net
     income (loss) of the Company and its consolidated Subsidiaries determined
     in accordance with GAAP; provided, however, that there shall not be
     included in such Consolidated Net Income: (i) any net income (loss) of any
     person acquired by the Company or any of its Restricted Subsidiaries in a
     pooling of interests transaction for any period prior to the date of such
     acquisition, (ii) any net income of any Restricted Subsidiary of the
     Company if such Restricted Subsidiary is subject to restrictions, directly
     or indirectly, on the payment of dividends or the making of distributions
     by such Restricted Subsidiary, directly or indirectly, to the Company
     (other than restrictions in effect on the Issue Date with respect to a
     Restricted Subsidiary of the Company and other than restrictions that are
     created or exist in compliance with Section 4.10 of this Indenture), (iii)
     any gain or loss realized upon the sale or other disposition of any assets
     of the Company or its consolidated Restricted Subsidiaries (including
     pursuant to any Sale/Leaseback Transaction) which are not sold or otherwise
     disposed of in the ordinary course of business and any gain or loss
     realized upon the sale or other disposition of any Capital Stock of any
     Person, (iv) any extraordinary gain or loss, provided that for purposes of
     this clause (iv), any gain or loss realized by the Company upon the
     repurchase of Notes shall be treated as an extraordinary gain

                                       3
<PAGE>

     or loss, and the costs incurred by the Company in soliciting consents to
     amend this Indenture from time to time (including, without limitation, the
     making of consent solicitation payments) shall not be treated as an
     extraordinary loss, (v) the cumulative effect of a change in accounting
     principles, (vi) the net income of any Person, other than a Restricted
     Subsidiary, except to the extent of the lesser of (A) cash dividends or
     distributions actually paid to the Company or any of its Restricted
     Subsidiaries by such Person and (B) the net income of such Person (but in
     no event less than zero), and the net loss of such Person (other than an
     Unrestricted Subsidiary) shall be included only to the extent of the
     aggregate Investment of the Company or any of its Restricted Subsidiaries
     in such Person and (viii) any non-cash expenses attributable to grants or
     exercises of employee stock options. Notwithstanding the foregoing, for the
     purpose of Section 4.4 of this Indenture only, there shall be excluded from
     Consolidated Net Income any dividends, repayments of loans or advances or
     other transfers of assets from Unrestricted Subsidiaries to the Company or
     a Restricted Subsidiary to the extent such dividends, repayments or
     transfers increase the amount of Restricted Payments permitted pursuant to
     clause (a)(3)(D) thereof.

     B.   New definitions of "Eligible Account Receivable" and "Securitization"
are hereby added as follows:

     "Eligible Account Receivable" means any account receivable, net of any
prepayments, progress payments, deposits and retentions, owing to the Company or
to a special purpose entity upon assignment thereto by the Company in connection
with a Securitization, provided that the account meets the following
specifications:

          (a)  The account is not more than one hundred and twenty (120) days
          from the date of the invoice therefor;

          (b)  The account is not subject to any prior assignment, claim, lien,
          or security interest other than in connection with a Securitzation,
          and the Company will not make any further assignment of the account or
          create any further security interest in the account, nor permit its
          rights in the account to be reached by attachment, levy, garnishment
          or other judicial process;

          (c)  The account arose in the ordinary course of the Company's
          business or was acquired by the Company;

          (d)  The account does not arise with respect to an account debtor from
          whom fifty percent (50%) or more of the accounts are more than one
          hundred and twenty days (120) from the date of the invoice therefore;
          and

          (e)  No notice of bankruptcy, insolvency or material adverse change of
          the account debtor has been received by or is known to the Company.

     "Securitization" means the sale of accounts receivable for cash to a
     special purpose entity without recourse to the seller of such accounts
     receivable.

          principal amount not to exceed $90,000,000, (ii) Additional Private
