                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT made as of November 15, 1994 by and between MERCURY AIR
GROUP, INC., a New York corporation having its principal offices at 5456
McConnell Avenue, Los Angeles, California 9OO66 (hereinafter referred to as
"Employer"), and Mr. Joseph A. Czyzyk, residing at 8141 Cabora Drive, Playa Del
Rey, California 90293 (hereinafter referred to as "Employee").

                              W I T N E S S E T H:

         WHEREAS, Employee has been employed as President of Mercury Air Cargo,
Inc., a California corporation and wholly-owned subsidiary of Employer ("MAC"),
since 1988 and currently serves as an Executive Vice President of Employer;

         WHEREAS, Employee's employment agreement with MAC has expired;

         WHEREAS, Employer's Board of Directors (the "Board of Directors") would
like to employ Employee as its President/Chief Operating Officer, continue
Employee's role as President of MAC and appoint Employee to serve as a director
of Employer, on the terms and conditions set forth in this Agreement; and

         WHEREAS, Employee wishes to accept these positions on the terms and
conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants hereinafter
contained, the parties agree as follows:

         First:   Employment; Appointment as a Director; Expression of Intent

         (a) Employment. Employer hereby confirms and agrees that Employee has
been elected by the Board of Directors to act as Employer's President/Chief
Operating Officer and in such capacity to provide executive services as the
senior executive officer responsible for directing the day-to-day operations and
sales functions for Employer's government contracts, cargo, fuel sales,
commercial aviation services and fixed base operation units and any subsequently
formed operating units of Employer. Employer further confirms that Employee has
been elected by the Board of Directors of MAC to continue serving as the
President of MAC. In both capacities, Employee shall report directly to
Employer's Chief Executive Officer/Chairman of the Board.

         (b) Appointment as Director. The size of the Board of Directors has
been expanded to six (6) members, creating a single vacancy, and Employee has
been appointed and elected by the Board of Directors to fill such vacancy.
Employee understands that the directors of Employer are elected by the
shareholders of Employer on an annual basis and no assurance can be given
regarding his retention of this position. The Board of Directors, however,
agrees to maintain Employee as one of the candidates nominated by the Board of
Directors in connection with each annual meeting of shareholders for so long as
he serves as the Chief Operating Officer/President of Employer.


                                  Exhibit 10.13
                                                                    Page 1 of 10

         (c) Employee's Acceptance. Employee hereby accepts his appointments and
elections as President/Chief Operating Officer of Employer, President of MAC and
as a director of Employer.

         (d) Intent. It is the intent of the Board of Directors that Employee's
tenure as Chief Operating Officer/President of Employer shall serve as a period
of training and evaluation for appointment to the office of Chief Executive
Officer of Employer, when and as such position may be vacated by Mr. Seymour
Kahn. Any such appointment to the position of Chief Executive Officer of
Employer shall be made in the sole discretion and judgement of the Board of
Directors.

         Second:           Term

    Subject to the provisions governing termination as hereinafter provided, the
term of this Agreement shall begin on November 15, 1994 and shall terminate on
November 15, 1997. If Employee is then employed by Employer, on each successive
November 15, the term of this Agreement shall be automatically extended for one
additional year such that the remaining term of the Agreement shall then be
three (3) years; provided, however, that upon written notice given by either
party at least thirty (30) days prior to the next automatic extension, the
automatic extension right may be terminated.

         Third:            Compensation

         (a) Base Compensation. For all services rendered by Employee under this
Agreement, Employer shall pay Employee a salary of $270,000 per year, payable in
semi-monthly installments in accordance with Employer's standard payroll
practices. From time to time, the salary payable to Employee may be increased at
the sole discretion of the Compensation Committee of the Board of Directors (the
"Compensation Committee"). Employee's annual salary, as from time to time
increased by the Compensation Committee, is hereinafter referred to as "Base
Compensation."

         (b) Bonus Plans. In addition, the Compensation Committee has enacted
the following Bonus Plan for Employee, which shall be maintained in effect
during the term of this Agreement. For purposes of the bonus plan, EBIT shall be
defined as Operating Income of Employer on a consolidated basis minus Sales and
General Administrative Expense and Depreciation of Employer on a consolidated
basis. For Fiscal 1995, Employee shall receive a bonus: (i) under Part I of the
bonus plan, equal to Twenty-Five Percent (25%) of his Base Compensation if
Fiscal 1995 EBIT meets or exceeds EBIT for Fiscal 1994; and (ii) under Part II
of the bonus plan, equal to Two and One-Half Percent (2.5%) of the amount by
which Fiscal 1995 EBIT exceeds Fiscal 1994 EBIT. Any bonus received by Employee
for Fiscal 1995 shall be solely at the discretion of the Compensation Committee,
if Fiscal 1995 EBIT does not meet or exceed Fiscal 1994 EBIT. For Fiscal 1996,
Part I and Part II of the bonus plan shall remain in effect except that the
threshold EBIT shall be based on the average of EBIT for Fiscal 1994 and 1995.
For fiscal years subsequent to Fiscal 1996, Part I and Part II of the bonus plan
shall remain in effect except that the threshold EBIT shall be based on a
trailing average of EBIT for the prior three (3) fiscal years.

                                                                    Page 2 of 10

         (c) Signing Bonus. Upon execution of this Agreement, Employee shall be
paid a signing bonus of One Hundred Thousand Dollars ($100,000).

         Fourth:           Extent of Services

    Employee shall devote his entire time, attention and energies to the
business of Employer (and its various subsidiaries) and shall not during the
term of this Agreement be engaged in any other business activity whether or not
such business activity is pursued for gain, profit or other pecuniary advantage;
but this shall not be construed as preventing Employee from investing his assets
in companies or other entities in such form or manner as will not require any
services on the part of Employee in the operation of the affairs of such
companies or entities in which such investments are made, and, with respect to
companies or other entities which are competitors of Employer, where Employee's
investment does not represent in excess of Ten Percent (10%) of the outstanding
equity of such company or entity, a loan in excess of Ten Percent (10%) of the
net assets of such company or entity or any combination of the foregoing
totaling Ten Percent (10%).

         Fifth:            Working Facilities

     Employee shall be furnished with a private office, secretarial help and
other facilities and services reasonably suitable to his position and adequate
for the performance of his duties. Employee shall be employed at Employer's
principal executive offices in Los Angeles, California and shall travel to the
extent necessary to fulfill his duties in his discretion.

         Sixth:            Disclosure of Information

         (a) Generally. The parties acknowledge that Employer and its affiliates
(individually and collectively, the "Companies"), have developed and intend to
continue the development of and to formulate, acquire and use commercially
valuable technical and non-technical information, design and specification
documents, concepts, technology, know-how, improvements, proposals, patent
applications, techniques, marketing plans, strategies, forecasts, inventions
(not limited by the definition of an invention contained in the United States
Patent Laws), Trade Secrets (as defined in Sec. 3426.1(d) of the Uniform Trade
Secrets Act) and processes which are considered proprietary by the Companies,
particularly including, without limitation, customer and supplier lists, books
and records, computer programs, pricing information and business plans
(collectively, the "Propriety Information"). It is necessary for the Companies
to protect the Proprietary Information by patents or copyrights or by holding it
secret and confidential.

         (b) Access to Proprietary Information. The parties acknowledge that
Employee has access to the Proprietary Information and that the disclosure or
misuse of such Proprietary Information could irreparably damage the Companies
and/or their respective clients or customers.

         (c) Nondisclosure to Others. Except as directed by Employer in writing
or verbally, Employee shall not at any time during or after the Term disclose
any Proprietary Information to any person whatsoever, examine or make copies of
any reports or other documents, papers, memoranda or extracts for use other than
in connection with his duties with Employer or utilize for his own


                                  Exhibit 10.13
                                                                    Page 3 of 10

<PAGE>   4

benefit or for the benefit of any other party any such Proprietary Information
and will use reasonable diligence to maintain the confidential, secret or
proprietary character of all Proprietary Information.

         (d) Survivability. Employee acknowledges that his obligations hereunder
shall continue beyond the Term with respect to any Proprietary Information (as
defined in Article Sixth, paragraph (a) hereof) which came into his possession
during the Term.

         Seventh:          Expenses

         Employee is authorized to incur reasonable expenses for promoting the
business of Employer, including expenses for entertainment, travel and similar
items but only in accordance with the policies of the Board of Directors or
Employer's Chief Executive Officer, as from time to time adopted. Employer will
reimburse Employee for all such reasonable expenses upon the presentation by
Employee, from time to time, of an itemized account and documentation of such
expenditures in sufficient detail to allow Employer to claim an income tax
deduction for each paid item, if such item is deductible.

         Eighth:           Fringe Benefits

         (a) Participation in General Plans. Subject to the provisions of
paragraph (b) below, Employee shall have such employee benefits (including
medical insurance, life insurance, 401(k) and disability insurance plans) as
Employer shall from time-to-time establish, promulgate or keep in effect for the
benefit of its management level employees. Such benefits will include company
paid medical insurance for Employee and his family under Employer's medical
insurance plans. Employee shall be required to comply with, and be entitled to
benefits only in accordance with, the terms and conditions of such plans.
Nothing contained in this paragraph (a) of Article Eighth, however, shall be
construed to require Employer to establish any life, disability or medical
insurance plans not in existence on the date hereof, to continue any plans in
existence on the date hereof, to prevent Employer from modifying and/or
terminating any of the plans in existence on the date hereof or otherwise
require Employer to take special steps to insure the eligibility of Employee or
his dependents under the provisions of such plans, and no such act or omission
shall be deemed to affect this Agreement or to require modification of the
compensation, additional benefit or other provisions contained herein. The
provisions of this paragraph (a) of Article Eighth shall not limit or modify
Employee's rights with respect to life insurance and payment following
disability specifically set forth in this Agreement.

         (b) Stock Options. By virtue of his appointment to the Board of
Directors, Employee shall no longer be eligible to participate in Employer's
stock option plans as presently constituted; provided, however, that the options
to purchase Twenty-Five Thousand (25,000) shares of Common Stock of Employer
currently held by Employee under the 1990 Long-Term Incentive Plan (the
"Existing Option") shall not be affected by this provision. Employee shall be
entitled to the grant of stock options outside of Employer's existing stock
option plans as from time to time determined in the sole discretion of the
Compensation Committee. Notwithstanding any other provision of this Agreement,
any options granted to Employee shall be exercisable for a minimum of Ninety
(90) days following his termination as set forth in the Existing Option
agreement.


                                 Exhibit 10.13
                                                                    Page 4 of 10

<PAGE>   5

         (c) Vacation. Employee shall be entitled each year to a vacation of
four (4) weeks, during which time his compensation shall be paid in full.

         Ninth:            Disability

         (a) Rights Following Disability. If Employee is unable to perform his
services by reason of illness or incapacity ("Disabled") for a period of more
than six (6) weeks as determined in the reasonable discretion of Employer's
Chief Executive Officer, the compensation otherwise payable to him during the
continued period of such illness or incapacity shall be reduced by fifty (50%)
percent. Unless this Agreement has been terminated prior thereto, Employee's
full compensation shall be reinstated effective and commencing on the date of
his return to employment and the discharge of his full duties hereunder.
Notwithstanding anything herein to the contrary, Employer may terminate this
Agreement at any time after Employee shall be Disabled for a period of more than
twelve (12) months as determined in the reasonable discretion of Employer's
Chief Executive Officer. Following any such termination: (i) Employer shall
continue to pay Employee's Base Compensation for one-year as severance pay or
such lesser period as may remain on the term of this Agreement; and (ii)
Employer shall pay to Employee a pro rated bonus for the portion of the fiscal
year during which he was employed prior to such termination. For purposes of the
foregoing pro ration, the bonus for the fiscal year in which the termination
occurs shall be calculated in accordance with the terms of and on the schedule
set forth in Article Third of this Agreement. Following such calculation, the
bonus for the total fiscal year shall be multiplied by a fraction, the numerator
of which shall be the number of days in the fiscal year of termination during
which Employee was employed by Employer, and the denominator of which shall be
365. The result of such calculation shall determine the pro rated bonus paid to
Employee. For purposes of this Article Ninth all amounts paid to Employee under
any long-term disability insurance policy maintained by Employer shall be
credited as if paid by Employer to Employee to Employee and after giving effect
to any federal or state income tax savings resulting from the payment under a
disability policy (as opposed to as taxable salary).

         (b) No Additional Rights. Except as set forth above in paragraph (a),
clauses (i) and (ii) of this Article Ninth, following a termination of
Employee's employment with Employer pursuant to paragraph (a) of this Article
Ninth: (i) all rights and liabilities of the parties hereto shall cease and this
Agreement shall be terminated (subject to the continuing obligations of Employee
pursuant to Articles Sixth and Fourteenth); and (ii) Employee shall not be
entitled to receive any severance benefits, salary, other benefits or
compensation of any kind (except for health insurance continuation as required
by COBRA and accrued vacation pay as required by law) either as consideration
for his employment or in connection with the termination of his employment.

         Tenth:            Employer's Right to Terminate For Cause

         (a) Cause. Employer may at any time during the term of this Agreement
discharge Employee for "cause." The term "cause" is defined herein as Employee's
acts of misappropriation of corporate funds, embezzlement, negligence or
Employee's voluntary abandonment of his job (other than pursuant to Article
Twelfth) or a material breach of this Agreement. Employee shall be terminated
only following a finding of "cause" in a resolution adopted by majority vote of
the Board


                                  Exhibit 10.13
                                                                    Page 5 of 10

of Directors, with Employee abstaining.

         (b) No Rights Following Cause Termination. Following a termination of
Employee's employment with Employer "for cause" pursuant to paragraph (a) of
this Article Tenth: (i) all rights and liabilities of the parties hereto shall
cease and this Agreement shall be terminated (subject to the continuing
obligations of Employee pursuant to Article Sixth and Fourteenth hereof); and
(ii) Employee shall not be entitled to receive any severance benefits, salary,
other benefits or compensation of any kind (except for health insurance
continuation as required by COBRA, salary accrued through the date of
termination and accrued vacation pay as required by law) either as consideration
for his employment or in connection with the termination of his employment. In
the event that Employee asserts that his voluntary termination was actually a
constructive termination, Employer shall be entitled to assert as "cause" for
such termination any grounds present at the time of such termination which the
Board of Directors could have asserted as "cause" if called upon to terminate
Employee.

         Eleventh:         Termination Without Cause

         (a) Rights Following Termination Without Cause. Should Employee be
discharged by Employer at any time during the term of this Agreement except as
provided in Article Tenth, Employer hereby agrees to: (i) pay Employee within
thirty (30) days from such discharge the lesser of one year's Base Compensation
or the Base Compensation that would otherwise be paid to him over the remaining
term of this Agreement; and (ii) Employer shall pay to Employee a pro rated
bonus for the portion of the fiscal year during which he was employed prior to
such termination. For purposes of the foregoing pro ration, the bonus for the
fiscal year in which the termination occurs shall be calculated in accordance
with the terms of and on the schedule set forth in Article Third of this
Agreement. Following such calculation, the bonus for the total fiscal year shall
be multiplied by a fraction, the numerator of which shall be the number of days
in the fiscal year of termination during which Employee was employed by
Employer, and the denominator of which shall be 365. The result of such
calculation shall determine the pro rated bonus paid to Employee.

         (b) No Additional Rights. Except as set forth above in paragraph (a),
clauses (i) and (ii) of this Article Eleventh following a termination of
Employee's employment by Employer other than pursuant to Article Tenth above:
(i) all rights and liabilities of the parties hereto shall cease and this
Agreement shall be terminated (subject to the continuing obligations of Employee
pursuant to Articles Sixth and Fourteenth); and (ii) Employee shall not be
entitled to receive any severance benefits, salary, other benefits or
compensation of any kind (except for health insurance continuation as required
by COBRA and accrued vacation pay as required by law) either as consideration
for his employment or in connection with the termination of his employment.

         Twelfth:          Right to Voluntary Termination By Employee

         (a)  Conditions for Termination by Employee.         In the event that:

         (i) Any "person" other than Seymour Kahn or an affiliate of Seymour
Kahn is or becomes a "beneficial" owner, "directly or indirectly", of stock of
Employer representing 50% or more of the total voting power of Employer's then
outstanding stock, without the written consent of Employee; or

         (ii) Employer is acquired by another entity through the purchase of
substantially all of the assets of the Companies, the purchase of all of
Employer's outstanding voting securities or a combination thereof, without the
written consent of Employee; or

         (iii) Employer is merged with another entity, consolidated with another
entity or reorganized in a manner in which any "person" other than Seymour Kahn
or an affiliate of Seymour Kahn is or becomes a "beneficial" owner, "directly or
indirectly", of stock of the surviving entity representing 50% or more of the
total voting power of the surviving entity's then outstanding stock, without the
written consent of Employee;

         then, if following any of the events set forth in clauses (i), (ii) or
(iii), Employee's duties are substantially altered or Employee is demoted for
cause, Employee shall have the right and option to voluntarily terminate this
Agreement upon written notice to Employer. All terms used in quotations in
clauses (i) and (iii) shall have the meanings assigned to such terms in Section
13 of the Securities Exchange Act of 1934 and the rules, regulations, releases
and no-action letters of the Securities and Exchange Commission promulgated
thereunder or interpreting any of the same. For purposes of clauses (i) and
(iii), the term "affiliate" shall have the meaning assigned to such term in Rule
144 promulgated by the Securities and Exchange Commission under the Securities
Act of 1933, as amended, and the releases and no-action letters interpreting the
same.

         (b) Rights Following Voluntary Termination After a Change of Control.
Following any voluntary termination of employment by Employee pursuant paragraph
(a) of this Article Twelfth, Employee shall be entitled to be paid by Employer
within thirty (30) days of such termination by Employee, the lesser of one
year's Base Compensation or the entire balance of his Base Compensation
remaining to be paid to Employee over the full remaining term of this Agreement.

         (c) No Additional Rights. Except as set forth above in paragraph (b) of
this Article Twelfth, following a voluntary termination of Employee's employment
with Employer pursuant to paragraph (a) of this Article Twelfth: (i) all rights
and liabilities of the parties hereto shall cease and this Agreement shall be
terminated (subject to the continuing obligations of Employee pursuant to
Articles Sixth and Fourteenth); and (ii) Employee shall not be entitled to
receive any severance benefits, salary, other benefits or compensation of any
kind (except for health insurance continuation as required by COBRA and accrued
vacation pay as required by law) either as consideration for his employment or
in connection with the termination of his employment.

         Thirteenth:       Death During Employment

<PAGE>   8

         If Employee dies during the term of this Agreement, Employer shall pay
to the estate of Employee the Base Compensation which would otherwise be payable
to Employee up to the end of the month in which his death occurs. In addition,
Employer shall maintain a life insurance policy or policies providing One
Million Dollars ($1,000,000)in death benefits payable to Employee's estate or
other designated beneficiary. Employee shall be entitled to and the owner of the
cash surrender value of all such insurance policies in excess of the premiums
paid by Employer (if any). Notwithstanding any other provision of this
Agreement, following any termination of Employee's employment with Employer: (a)
Employer shall cease paying the premiums on any such life insurance policy and
shall be entitled to withdraw (or be paid by Employee in the form of a set-off
against any severance payments due or otherwise) its portion of the cash
surrender value of the life insurance policies; and (b) Employee shall be
entitled, in his discretion, to continue such policies for his benefit by
payment of the premiums and shall be entitled to the full cash surrender value
of such policies following withdrawal or repayment of Employer's interest in the
cash surrender value. Employee and Employer will execute such assignments as are
necessary to reflect this allocation of the death and cash surrender values of
any life insurance policies paid for by Employer on the life of Employee.

         Fourteenth:       Restrictive Covenant

         Employee covenants and agrees that, during the period commencing with
the date hereof and ending five (5) years from the date Employee's employment
with Employer is terminated (the "Non- Compete Period"), Employee will not
compete or attempt to compete with or become associated with any business which
competes with the Companies' government contracts, cargo, commercial aviation,
fuel sales and fixed base operation activities or any business activities of the
Companies developed subsequent to the date hereof. Employee covenants and agrees
that he will not, without the prior written consent of Employer during the
Non-Compete Period: (a) solicit any customer of the Companies; (b) solicit any
contracts which were either being solicited by, or which were under contract
with, the Companies by performing or causing to be performed any work which was
either being solicited by, or which was under contract with, Employer; or (c)
induce any sales, operating, technical or other personnel of the Companies to
leave the service, employ or business of the Companies. Employee agrees that he

such method of violation referred to in clauses (a) through (d) shall
hereinafter be referred to as an "indirect violation"). Employee further agrees
that doing or causing to be done any of the actions prohibited in this Article
Fourteenth by means of an indirect violation shall constitute a violation of
this Article Fourteenth as though violated by Employee, subject to all of the
remedies to Employer provided for herein and as otherwise provided by law.
