                                             AMENDED AND RESTATED EMPLOYMENT
                                       AGREEMENT dated as of March 6, 2000 (the
                                       "AGREEMENT"), between OPUS360
                                       CORPORATION, a Delaware corporation (the
                                       "COMPANY"), and CARLOS B. CASHMAN (the
                                       "EMPLOYEE").

         The Company and the Employee are parties to the Existing Employment
Agreement (as defined herein), pursuant to which the Employee is presently
employed by the Company. In order to set forth the terms of the Employee's
continued employment with the Company, the Company and the Employee desire to
amend and restate the Existing Employment Agreement in its entirety as and
pursuant to this Agreement.

         NOW, THEREFORE, in consideration of the premises and of the mutual
agreements contained in this Agreement, the parties hereto agree that the
Existing Employment Agreement shall be amended and restated in its entirety to
read as follows:

1.       EMPLOYMENT.

         The Company shall employ the Employee, and the Employee accepts
employment with the Company, upon the terms and conditions set forth in this
Agreement.

2.       TERM.

         The Employee's employment hereunder shall be for the period (including
any extensions thereof, the "EMPLOYMENT PERIOD") commencing on the date of this
Agreement (the "EFFECTIVE DATE") and terminating on the earlier of (i) the
36-month anniversary of the Effective Date or (ii) the early termination
pursuant to SECTION 5 of the Employee's employment hereunder; PROVIDED, HOWEVER,
the Employment Period shall be extended automatically on each 12-month
anniversary of the Effective Date, beginning with the 36-month anniversary
thereof, in each case for an additional period of 12 months, unless the Company
or the Employee notifies the other party at least 30 days prior to any such
anniversary date of its or his election that the Employment Period not be so
extended. The final date of the actual term of the Employee's employment with
the Company hereunder is referred to as the "TERMINATION DATE."

3.       POSITION, DUTIES AND RESPONSIBILITIES.

         (a) During the Employment Period, the Employee shall serve as the Chief
Technology Officer of the Company or in such other position as shall be
determined by the Board or the Chief Executive Officer or President of the
Company.

         (b) During the Employment Period, the Employee shall devote all of his
business and professional time, attention, energy, loyalty and skill to the
business of the Company and its Subsidiaries as may be reasonably necessary to
carry on the business of the Company and its Subsidiaries and to perform his
duties under this Agreement.

         (c) Notwithstanding anything contained in SECTION 3(b) to the contrary,
during the Employment Period, the Employee shall not be prohibited from (i)
serving as an officer, director,


<PAGE>

trustee or otherwise participating in purely educational, welfare, social,
charitable, religious and civic organizations, or (ii) managing personal and
family investments or serving as an executor or trustee or in a similar
fiduciary capacity, in each case to the extent such activities (A) do not
interfere or conflict in any material respect with the performance of his duties
and responsibilities hereunder and (B) are conducted in accordance with the
limitations of SECTION 10. During the Employment Period, subject to the
limitations of SECTION 10, the Employee may serve on the board of directors or
similar body of any business entity or make passive investments in any business
entities (the exercise by the Employee of his voting rights as a member of the
board of directors or similar governing body of any such entity or the
Employee's acting as an informal advisor to any such entity from time to time
being understood to not, on such basis alone, preclude any such investment from
being deemed passive in nature), but only if, in each such case, such service or
investment does not unreasonably conflict or interfere with the performance of
the Employee's duties and responsibilities hereunder. The Employee has notified
the Board of all directorships or similar positions held by him on the Effective
Date and shall promptly notify the Board of his election or appointment to any
other directorships or similar positions after the Effective Date.

4.       BASE SALARY, FRINGE BENEFITS AND OPTION.

         (a) During the Employment Period, the Employee's base salary shall be
$125,000 per annum or such higher rate as the Board or its designee may specify
from time to time (the "BASE SALARY"). The Employee's Base Salary will be
payable in equal installments in accordance with the general policies of the
Company regarding compensation of senior executives of the Company. During the
Employment Period, in addition to the Base Salary, the Employee shall be
entitled to receive an annual bonus (the "BONUS") as determined by the Board or
its designee (in its sole discretion), taking into account, among other things,
the performance of the Employee and the financial and operational performance of
the Company.

         (b) During the Employment Period, the Employee shall be eligible to
participate in all Company-sponsored employee benefit plans (the "EMPLOYEE
BENEFIT PLANS"), including all employee retirement income and welfare benefit,
pension, disability, group life, sickness or accident or health insurance
policies, plans, programs or arrangements, if any, that are generally available
to other employees of the Company at substantially the same employment level as
the Employee for their participation, subject to the terms and conditions of
such plans, as they may be amended from time to time (collectively, the
"EMPLOYEE BENEFITS").

         (c) During the Employment Period, the Employee shall be entitled to
three weeks of vacation during each 12-month period worked, commencing on the
Effective Date. Such vacation shall be in accordance with the terms generally
applicable to other employees of the Company at substantially the same
employment level as the Employee, as in effect from time to time. The Employee
may take his vacation at such time or times as shall not interfere with the
performance of his duties under this Agreement. The Employee shall be entitled
to paid sick leave and holidays in accordance with the sick leave and holiday
policies as may be generally applicable to senior executives of the Company, as
in effect from time to time.

         (d) The Company shall reimburse the Employee for all reasonable travel,
entertainment and other business expenses incurred by him in the course of
performing his duties



                                       2
<PAGE>

under this Agreement in accordance with the Company's policies and rules in
effect from time to time relating to the reimbursement of such expenses. Any
determination of the reasonableness of such expenses shall take into account the
position and level of responsibility of the Employee within the Company.

         (e) The Employee authorizes the Company to deduct from any amounts
payable to him hereunder such sums as may be required to be deducted or withheld
under the provisions of any federal, state or local law or regulation now in
effect or hereafter put into effect during the term of this Agreement,
including, without limitation, social security and income withholding taxes.

5.       EARLY TERMINATION OF EMPLOYMENT.

         (a) The early termination of the Employee's employment hereunder shall
result upon the first to occur of (i) the termination of such employment by the
Company, at any time, for Cause, without Cause or by reason of the Disability of
the Employee, (ii) the death of the Employee and (iii) the resignation of the
Employee from such employment, at any time, for Good Reason or without Good
Reason.

         (b) For purposes of this Agreement, the term "CAUSE" means (i) the
gross negligence or willful misconduct by the Employee in the performance of his
duties, (ii) the commission by the Employee of any act of fraud, theft or
financial dishonesty with respect to the Company or any of its Subsidiaries or
if Employee is convicted of a felony, (iii) the material breach by the Employee
of this Agreement (including, but not limited to, any breach or threatened
breach by the Employee of the provisions of SECTIONS 7, 8, 9 or 10), or (iv) the
willful disregard, or failure to follow written instructions from, the President
of the Company, the Board or any of their designees, to perform any legal act
relating to the business of the Company or its Subsidiaries which would be
commensurate with the usual and customary duties, responsibilities and authority
of the Chief Technology Officer of the Company or such other position held by
the Employee as may be determined by the Board or the Chief Executive Officer or
President of the Company or otherwise consistent with such position. Before the
Employee's employment with the Company hereunder may be terminated by the
Company for Cause, the Employee shall have 10 days after written notice of such
basis for termination to cure such basis for termination; PROVIDED, HOWEVER, no
such right to cure shall exist if the basis for such termination is incurable or
if otherwise any of the acts referred to in CLAUSE (i) of the definition of
"CAUSE" have been committed by the Employee.

         (c) Any determination as to whether the Employee is subject to a
Disability shall first be made by the Board (excluding the Employee if he should
be a member of the Board at the time of such determination) in its good faith
judgment; PROVIDED, HOWEVER, if any such determination is disputed by the
Employee, the matter shall be referred to a licensed physician practicing within
the Borough of New York in the State of New York or a 50-mile radius thereof and
selected by the Board and the Employee, and the determination of Disability made
by such physician shall be final and binding on both the Employee and the
Company. For purposes of this Agreement, the term "DISABILITY" means any
long-term disability or incapacity which renders, or would be reasonably
expected to render, the Employee unable to substantially



                                       3
<PAGE>

perform his duties and responsibilities hereunder for a cumulative total of 90
days during any 12-month period.

         (d) For purposes of this Agreement, "GOOD REASON" means (i) a reduction
of the Base Salary of the Employee as in effect on the Effective Date by more
than ten percent (10%), where such reduction is not cured within 30 days after
written notice thereof by the Employee to the Company, (ii) the removal by the
Company of the Employee from the position of Chief Technology Officer of the
Company, without any election or appointment of the Employee to a position of
comparable or greater seniority with the Company, where such removal is not
rescinded, or such election or appointment does not occur, within 10 days after
written notice thereof by the Employee to the Company, or (iii) a material
breach by the Company of this Agreement, which breach is incurable or otherwise
not cured within 10 days after written notice thereof by the Employee to the
Company, in each case without the prior written consent or waiver of the
Employee.

employment with the Company hereunder based on the election of the Company or

the Company with Cause or by reason of the Employee's resignation without Good

         shall be entitled to receive any benefits under any Employee Benefit
         Plan that have accrued during any period if the terms of such Employee
         Benefit Plan require that the Employee be employed by the Company or
         any Subsidiary thereof as of the end of such period).

employment with the Company hereunder either by the Company without Cause or by
reason of the Employee's resignation with Good Reason, neither the Employee nor

the course of his employment with the Company or any of its Subsidiaries on or

lend funds to or otherwise finance, be employed by, have a financial or other
interest in, or in any manner engage in or represent any business which is
competing with any business of the Company or any Subsidiary thereof as such

formed or acquired, at any time from the date on which the Employee's employment
with the Company first began (whether on or before the Effective Date) up to
(and including) the Termination Date, within any Restricted Territory.

         (b) During the Employment Period and the Non-Compete Period, the

         (c) The Employee understands that the restrictions set forth in this

the business of the Company or any of its Subsidiaries, but the Employee
nevertheless believes that he has received and shall receive sufficient
consideration and other benefits as provided hereunder and pursuant to other
agreements to which he and the Company are parties, which in any event he does
not believe (given his education, skills and ability) would prevent him from
otherwise earning a living.

otherwise, its own life, disability, accident or other insurance covering the

such requested assistance does not unreasonably interfere with the business time
requirements of any third-party services the Employee is then obligated to
perform (whether as an employee, consultant or otherwise).

17.      GENERAL PROVISIONS.

         (a) SEVERABILITY/ENFORCEMENT.

                  (i) It is the desire and intent of the parties hereto that the
         provisions of this Agreement be enforced to the fullest extent
         permissible under the laws and public policies applied in each
         jurisdiction in which enforcement is sought. Accordingly, if any
         particular provision of this Agreement shall be adjudicated by a court
         of competent jurisdiction to be invalid, prohibited or unenforceable
         for any reason, such provision, as to such jurisdiction, shall be
         ineffective, without invalidating the remaining provisions of this
         Agreement or affecting the validity or enforceability of this Agreement
         or affecting the validity or enforceability of such provision in any
         other jurisdiction. Notwithstanding the foregoing, if such provision
         could be more narrowly drawn so as not to be invalid, prohibited or
         unenforceable in such jurisdiction, it shall, as to such jurisdiction,
         be so narrowly drawn, without invalidating the remaining provisions of
         this Agreement or affecting the validity or enforceability of such
         provision in any other jurisdiction. Without limiting the generality of
         the preceding sentence, if at the time of enforcement of SECTIONS 7, 8,
         9 or 10 of this Agreement, a court holds that the restrictions stated
         therein are unreasonable under circumstances then existing, the parties
         hereto agree that the maximum period, scope or geographical area
         reasonable under such circumstances shall be substituted for the
         stated period, scope or area.

                  (ii) The Company and the Employee shall each have and retain
         all other rights and remedies existing in their favor at law or equity,
         including, without limitation, any actions for specific performance
         and/or injunctive or other equitable relief to enforce or prevent any
         violations of the provisions of this Agreement. Because the Employee's
         services are unique and because the Employee has access to Confidential
         Information and Work Product, the parties hereto agree that money
         damages would be an inadequate remedy for any breach of this Agreement.
         Therefore, in the event of a breach or threatened breach by the
         Employee of SECTIONS 7, 8, 9 or 10, the Company or its successors or
         assigns may, in addition to any other rights and remedies existing in
         their favor, apply to any court of competent jurisdiction for specific
         performance and/or injunctive or other relief in order to enforce, or
         prevent any violations of, such provisions (without posting a bond or
         other security) or require the Employee to account for and pay



                                       11
<PAGE>

         over to the Company all compensation, profits, moneys, accruals and
         increments derived or received by him as a result of any transactions
         constituting a breach of such provisions.

                  (iii) In addition to the foregoing, and not in any way in
         limitation thereof, or in limitation of any right or remedy otherwise
         available to the Company, if the Company shall determine that the
         Employee is in violation of any provision of SECTIONS 7, 8, 9 or 10 of
         this Agreement (such determination being made before any judgment or
         decision with respect to such question shall be made by a court of
         competent jurisdiction), the Company may withhold any severance
         payments then or thereafter due from the Company to the Employee, until
         there shall be a final judgment or decision by a court of competent
         jurisdiction that no such violation shall have occurred, in which case
         (A) the Company shall pay to the Employee, within five (5) Business
         Days after such judgment or decision, such amounts of severance under
         this Agreement previously withheld from payment by the Company,
         together with interest on such amounts withheld at a floating rate per
         annum equal to the prime rate announced from time to time by the Wall
         Street Journal as the prevailing "PRIME RATE" at U.S. money center
         banks, and (B) the Company shall reimburse the Employee for his
         reasonable attorneys fees and expenses incurred in connection with the
         issuance of such judgment or decision within five (5) Business Days of
         the receipt by the Company of reasonable supporting documentation
         therefor. If the Employee is determined by a judgment or decision of a
         court of competent jurisdiction to have violated any provision of
         SECTIONS 7, 8, 9 or 10 of this Agreement, the Company's obligation to
         pay and the Employee's right to receive any severance payments under
         this Agreement on or after the date on which such violation shall have
         first occurred (whether already paid or otherwise) shall terminate and
         be of no further force or effect, and, within five (5) Business Days of
         any such judgment or decision, the Employee shall return to the Company
         any such severance payments already made by the Company.

                  (iv) The Employee's obligations under SECTIONS 7, 8, 9 or 10
         shall not be limited or affected by, and such provisions shall remain
         in full force and effect notwithstanding, the termination of any
         severance payments by the Company in accordance with SECTION
         17(a)(iii). The exercise of by the Company of its right to terminate
         such payments pursuant to SECTION 17(a)(iii) shall not be deemed to be
         an election of remedies by the Company and shall not in any manner
         modify, limit or preclude the Company from exercising any other rights
         or seeking any other remedies available to it at law or in equity.

         (b) COMPLETE AGREEMENT. This Agreement amends and restates the Existing
Employment Agreement in its entirety, and this Agreement, together the
Repurchase Agreement, constitutes the sole and entire agreement between the
parties hereto with respect to the subject matter hereof and thereof and
supersedes all prior or contemporaneous arrangements or understandings with
respect hereto or thereto, including the Existing Employment Agreement, and the
parties hereto hereby forever release, waive and disclaim any and all rights
under the Existing Employment Agreement.

         (c) RIGHT OF SET OFF. The Company is authorized, on or after the
termination of the Employment Period by the Company for Cause, to the fullest
extent permitted by law, to set off and apply any and all amounts at any time
payable by the Company to the Employee under



                                       12
<PAGE>

this Agreement, against any and all of the obligations of the Employee to the
Company now or hereafter existing under this Agreement or any other agreement or
contract between the Employee on the one hand and the Company or any of its
Subsidiaries on the other hand.

         (d) SUCCESSORS AND ASSIGNS. This Agreement will be binding upon and
inure to the benefit of the Company, the Employee and each of their respective
successors, assigns, personal and legal representatives, executors,
administrators, heirs, distributees, devisees, and legatees, as applicable;
PROVIDED, HOWEVER, that neither this Agreement nor any rights or obligations
hereunder will be assignable or otherwise subject to hypothecation by the
Employee (except by will or by operation of the laws of intestate succession).

         (e) GOVERNING LAW; CHOICE OF JURISDICTION AND VENUE. THE PROVISIONS OF
THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK APPLICABLE TO CONTRACTS ENTERED INTO AND FULLY PERFORMED
WITHIN THE STATE OF NEW YORK BY RESIDENTS OF THE STATE OF NEW YORK. WITH RESPECT
TO ANY LAWSUIT OR PROCEEDING BROUGHT WITH RESPECT TO THIS AGREEMENT, EACH OF THE
PARTIES HERETO IRREVOCABLY (I) SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE
COURTS OF THE STATE OF NEW YORK OR FEDERAL COURT OF THE UNITED STATES OF AMERICA
SITTING IN NEW YORK, (II) WAIVES ANY OBJECTION IT MAY HAVE AT ANY TIME TO THE
LAYING OF VENUE OF ANY PROCEEDING BROUGHT IN ANY SUCH COURT, (III) WAIVES ANY
CLAIM THAT SUCH PROCEEDING HAS BEEN BROUGHT IN AN INCONVENIENT FORUM, AND (IV)
FURTHER WAIVES THE RIGHT TO OBJECT, WITH RESPECT TO SUCH PROCEEDINGS, THAT SUCH
COURT DOES NOT HAVE JURISDICTION OVER SUCH PARTY.

         (f) WAIVER OF JURY TRIAL. Each of the parties hereto hereby irrevocably
waives all right to trial by jury in any action, proceeding or counterclaim
arising out of or relating to this Agreement.

         (g) AMENDMENT AND WAIVER. The provisions of this Agreement may be
amended and waived only with the prior written consent of the Company (upon the
written approval of the Board (excluding the Employee if he should be a member
of the Board at the time of such determination)) and the Employee, and no course
of conduct or failure or delay in enforcing the provisions of this Agreement
shall affect the validity, binding effect or enforceability of this Agreement or
any provision hereof.

         (h) HEADINGS. The section headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

         (i) COUNTERPARTS. This Agreement may be executed in two counterparts,
each of which shall be deemed an original and all of which together shall
constitute one and the same instrument.



                                       13

         (j) BUSINESS DAYS. If any time period for giving notice or taking
action hereunder expires on a day which is not a Business Day, the time period
for giving notice or taking action shall be automatically extended to the
immediately following Business Day.

         (k) SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS. All
representations, warranties and agreements contained herein shall survive in
perpetuity the consummation of the transactions contemplated hereby.

         (l) NOUNS AND PRONOUNS. Whenever the context may require, any pronouns
used herein shall include the corresponding masculine, feminine or neuter forms,
and the singular form of nouns and pronouns shall include the plural and
vice-versa.

         (m) CONSTRUCTION. Where specific language (such as the word
"INCLUDING") is used to clarify by example a general statement contained herein,
such specific language shall not be deemed to modify, limit or restrict in any
manner the construction of the general statement to which it relates. The
language used in this Agreement shall be deemed to be the language chosen by the
parties hereto to express their mutual intent, and no rule of strict
construction shall be applied against any party hereto. The parties hereto have
participated jointly in the negotiation and drafting of this Agreement. In the
event an ambiguity or question of intent or interpretation arises, this
Agreement shall be construed as if drafted jointly by the parties hereto, and no
presumption or burden of proof shall arise favoring or disfavoring any party by
virtue of the authorship of any of the provisions of this Agreement.
