                  Holdings and Employee agree to the following rights,
obligations and duties with respect to employment:

                  2.1 EMPLOYMENT. During the Employment Period, Holdings agrees
to employ the Employee as Senior Vice President of Atlas and of Holdings. The
scope of Employee's responsibilities shall be as determined by the Boards of
Directors of Atlas and/or Holdings, and/or appropriate officers of Atlas and/or
Holdings. If the Board of Directors of Holdings requests Employee to serve in
any capacity, Employee agrees that Employee shall serve in such capacity,
without any additional compensation. In addition, Employee shall not be entitled
to any additional compensation for serving in any other office for Atlas or
Holdings or any subsidiary or affiliate of Atlas or Holdings. Employee

connection with the appointment of a new Chief Executive Officer.

                  2.2 OBLIGATIONS OF EMPLOYEE. During the Employment Period, the

<PAGE>

                  2.3 PRINCIPAL RESIDENCE OF EMPLOYEE. During the Employment
Period, Employee shall maintain Employee's principal residence in the Purchase,
New York area.

3.   COMPENSATION

                  During the Employment Period, Atlas will pay Employee as
follows:

                  3.1 BASE ANNUAL SALARY. Atlas will pay Employee a base annual
salary (the "Base Annual Salary") of USD $300,000 per annum, payable in
semi-monthly installments. The Base Annual Salary shall be increased by $12,000
at the conclusion of the Employee's current company automobile lease in partial
consideration for the prospective elimination of such automobile allowance.
Holdings shall review Base Annual Salary not less frequently than annually for
increases, including among other considerations, Employee's performance, it
being understood that any increases shall be at the discretion of Holdings.

                  3.2 INCENTIVE BONUS PAYMENTS. Employee will be eligible to
participate in Holdings' Annual Incentive Plan. The level of the bonus available
to Employee will be set forth in the Annual Incentive Plan and will be awarded
in consideration of individual and corporate performance based on performance
goals and objectives determined by the Atlas Compensation Committee. A fuller
description of how corporate and individual performance operate in tandem to
determine the calculation of bonuses will be described in the Annual Incentive
Plan. The Annual Incentive Plan document will be developed by the Holdings
Compensation Committee and is subject to amendment from time to time with
changes as adopted by the Compensation Committee or full Board of Directors of
Holdings. As further described in the Annual Incentive Plan, corporate and
individual performance in combination may permit the Employee to earn a target
bonus equal to 50% of Base Annual Salary. Lesser corporate or individual
performance may cause bonus payments to be in an amount less than 50% of Base
Annual Salary or result in no bonus being payable.

                                       4
<PAGE>

Greater corporate and individual performances may result in the bonus being more
than 50% of Base Annual Salary. When the bonus payment reaches more than 50% of
Base Annual Salary, Atlas reserves the right to pay some or all of the portion
of the bonus that is above 50% of Base Annual Salary in Atlas unrestricted
company stock payable under the Atlas Air Worldwide Holdings, Inc. 2004 Long
Term Incentive and Share Award Plan. Any bonus paid under the Annual Incentive
Plan will be paid no later than two weeks following the completion of the
year-end audit for the applicable year.

                  3.3 BENEFITS. Employee and Employee's dependents shall be
entitled to participate in the Atlas health insurance plan, provided that the
Employee and Atlas will each contribute to Employee's monthly premium as
provided by such plan. Atlas reserves the right to discontinue participation in
any health insurance plan at any time, provided that Atlas will reimburse
Employee for Employee's cost of obtaining comparable health care benefits for
Employee and his dependents. Employee also shall be entitled, to the same extent
and at a level commensurate with the corporate officers of Atlas, to participate
in any other benefit plans or arrangements of Atlas.

                  3.4 FRINGE BENEFITS. (a) Employee will continue to enjoy the
use of the automobile currently leased by him for the duration of the lease, at
the company's expense. At the conclusion of the current lease, Employee will
receive a one-time cash payment of $19,000 in lieu of the tax gross-up related
to his automobile allowance.

                      (b) In consideration of the reduction of the severance
payment described in Section 4.2(a)(i) from the eighteen (18) months previously
provided to twelve (12) months, Employee will receive a one-time cash payment of
$127,500. This payment shall be payable

                                       5
<PAGE>

within ten (10) days after the signing of this Agreement and shall be subject to
required tax withholding.

                      (c) The Employee will be entitled to four (4) weeks of
paid vacation per year.

                      (d) In the event the Employee becomes entitled to
severance payments within six (6) months of the date of this Agreement, Employee
will receive a lump sum cash payment of $22,500, in addition to the severance
payment described in Section 4.2(a)(i).

                      (e) Upon the Employee's completion of six (6) months of
satisfactory employment from the date of this Agreement, Employee will receive a
grant of stock options in an amount sufficient to deliver the economic benefit
he would have received as a Senior Vice President from the most recent round of
grants to officers of Atlas made before the date of this Agreement, had he been
included at that time, which options would vest in accordance with the standard
vesting schedule. The Board of Directors of Holdings shall determine, in its
sole discretion, whether the Employee's performance for this six (6) month
period has been satisfactory.

4.   TERMINATION OF EMPLOYMENT PERIOD

                  The Employment Period shall terminate under the following
terms and conditions:

                  4.1 AT WILL ARRANGEMENT. Atlas and Employee expressly
understand and agree that the employment relationship is at-will. Either party
may terminate the Employment Period and the employment relationship upon written
notice to the other at any time and for any reason. Employee will make every
reasonable effort to give Holdings at least three months prior, written notice
of Employee's voluntary termination of employment for other than Good Reason.

                  4.2 RIGHTS FOLLOWING TERMINATION.

                  (a) If the Employment Period is terminated by Holdings for
reasons other than Cause or if the Employment Period is terminated by the

dates, twelve (12) months of Employee's monthly Base Salary; and (ii) continued
coverage and rights and benefits available under the employee benefit programs
of Atlas as provided in Section 3.3 above for a period of 12 months from the
date of termination; PROVIDED, HOWEVER, that any such continued coverage shall
cease in the event Employee obtains comparable coverage in connection with
subsequent employment, and to the extent Atlas is unable to continue such
coverage, Atlas shall provide the Employee with economically equivalent benefits
determined on an after-tax basis.

                  (b) Upon the death or Permanent Disability of the Employee,
the Employment Period shall terminate and the Employee's Base Annual Salary
which is accrued for the current pay period but unpaid as of the date of such

personal representative. In addition, upon the Permanent Disability of the
Employee, Employee shall be entitled to the compensation and benefits set forth
in Section 4.2 (a) (i) and (ii) above, and upon the death of Employee,
Employee's immediate family shall be entitled to the compensation and benefits
set forth in Section 4.2 (a) (i) and (ii) above.

                  (c) If the Employment Period is terminated by Holdings for
Cause or by the Employee for other than Good Reason, the Employee shall be
entitled to receive Employee's Base Annual Salary which is accrued for the
current pay period but unpaid as of the date of termination.

Restricted Share Agreement between Holdings and the Employee dated as of August
11, 2004, the Employee agrees that in the event of his termination by Holdings
for other than Cause occurring before January 27, 2006, he will not be entitled
to vest in the portion of the award granted in such Restricted Share Agreement
scheduled to vest in the twelve (12) month following such termination. This
provisions shall be considered a modification of the Restricted Stock Agreement
solely with respect to any such termination before January 27, 2006.

                  4.3 NON-COMPETITION PROVISION. (a) Employee covenants and
agrees that except when required to do so in the ordinary course of his duties,

Holdings, will Employee engage in any of the following activities directly or
indirectly, for any reason, whether for Employee's own account or for the

                  (i)      solicit, employ or otherwise interfere with any of
                           the Atlas Companies contracts or relationships with
                           any client, employee, officer, director or any
                           independent contractor whether the person is employed
                           by or associated with an Atlas Company on the date of

the applicable court or Arbitration tribunal; PROVIDED, HOWEVER, a reasonable
time for appearance is allowed. The Parties further agree that Arbitration
proceedings must be instituted within one (1) year after the occurrence of any
dispute, and failure to institute Arbitration proceedings within such time
period shall constitute an absolute bar to the institution of any proceedings
and a waiver of all claims. The Parties shall equally divide all costs and
expenses incurred in such proceeding and related legal proceedings; provided,
however, that Employee shall, if successful, be entitled to recover all his
costs and expenses including attorneys fees. The Judgment of the Arbitrator
shall be final and either Party may submit such decision to courts for
enforcement thereof.

6.   SEVERABILITY AND ENFORCEABILITY

                  It is expressly acknowledged and agreed that the covenants and
provisions, hereof are separable; that the enforceability of one covenant or
provision shall in no event affect the full enforceability of any other covenant
or provision herein. Further, it is agreed that, in the event any covenant or
provision of this Agreement is found by any court of competent jurisdiction or
Arbitrator to be unenforceable, illegal or invalid, such invalidity, illegality
or unenforceability shall not affect the validity or enforceability of any other
covenant or provision of this Agreement. In the event a court of competent
jurisdiction or an Arbitrator would otherwise hold any part hereof unenforceable
by reason of its geographic or business scope or duration, said part shall be
construed as if its geographic or business, scope or duration had been more
narrowly drafted so as not to be invalid or unenforceable.
