                         EXECUTIVE EMPLOYMENT AGREEMENT


                  This Executive Employment Agreement (this "AGREEMENT") is
dated as of December 20, 1996, between First Aviation Services Inc., a Delaware
corporation (the "COMPANY"), and John A. Marsalisi, an individual (the
"EXECUTIVE").


                                   WITNESSETH:

                  WHEREAS, the Company believes that the Executive is a valued
employee of the Company and wishes to ensure his continued employment with the
Company and document the terms of the Executive's employment by the Company.

                  WHEREAS, the Company also has determined that it is in the
best interests of the Company and its shareholders to reinforce and encourage
the continued attention and dedication of certain key members of the Company's
management, including the Executive, to their assigned duties without
distraction in uncertain circumstances arising from the possibility of a change
in control of the Company.

                  NOW, THEREFORE, taking into account the foregoing and in
consideration of the mutual promises and conditions contained herein, the
parties hereto agree as follows:


                                    ARTICLE I

                                   EMPLOYMENT


                  1.1 Employment. The Company employs the Executive and the
Executive hereby accepts employment as the Chief Financial Officer of the
Company and as the Chief Financial Officer of National Airmotive Corporation,
("NAC"), which is a wholly-owned subsidiary of the Company, upon the terms and
conditions hereinafter set forth.

                  1.2 Term. The employment of the Executive by the Company under
the terms and conditions of this Agreement will commence on the date hereof and
continue, subject to Article IV hereof, for a period of three years ("EMPLOYMENT
TERM").

                  1.3 Executive Duties. As the Company's Chief Financial Officer
and as NAC's Chief Financial Officer, the Executive shall perform such duties as
are requested by and shall report directly to the Company's Board of Directors.
The Executive agrees to devote his full business time (with allowances for
vacations and sick leave) and attention and best efforts to the affairs of the
Company and its subsidiaries and affiliates
<PAGE>   2
during the Employment Term, except that Executive shall be permitted to continue
his affiliation with, and work for, First Equity Development, Inc. so long as
such affiliation and work does not, in any material way, interfere with
Executive's duties as an officer of both the Company and NAC. Executive shall
not, while an employee of the Company, directly or indirectly, be engaged
(including as a stockholder, proprietor, general partner, limited partner,
trustee, consultant, employee, director, officer, lender investor or otherwise)
in any business or activity that is competitive with that of the Company or any
of its subsidiaries.


                                   ARTICLE II

                            COMPENSATION AND BENEFITS


                  2.1 Annual Salary. During the Employment Term, the Company
shall pay to the Executive a base salary at the rate of One Hundred Fifty-Five
Thousand Dollars ($155,000) per year (the "ANNUAL SALARY"), payable in
substantially equal biweekly installments. The Company will review annually and
may, in the sole discretion of the Board of Directors, increase such base salary
in light of the Executive's performance, inflation in cost of living or other
factors.

                  2.2 Benefits. During the Employment Term, the Executive shall
be eligible for participation in and covered by any and all such performance,
bonus, profit sharing, incentive, stock option, and other compensation plans and
such medical, dental, disability, life, and other insurance plans and such other
benefits generally available to other employees of the Company in similar
employment positions, on the same terms as such employees, subject to meeting
applicable eligibility requirements (collectively referred to herein as the
"COMPANY BENEFIT PLANS").

                  2.3 Reimbursement of Expenses. The Executive shall be entitled
to receive prompt reimbursement of all reasonable expenses incurred by the
Executive in performing services hereunder, including all reasonable expenses of
travel, entertainment and living expenses while away from home on business at
the request of, or in the service of, the Company or NAC, provided that such
expenses are incurred and accounted for in accordance with the policies and
procedures established by the Company.

                  2.4 Vacation and Holidays. The Executive shall be entitled to
an annual vacation leave of three (3) weeks at full pay or such greater vacation
benefits as may be provided for by the Company's vacation policies applicable to
senior executives of the Company. Up to a maximum of one week of vacation time
may be accumulated and carried over from one year to the next. Executive shall
be entitled to such holidays as are established by the Company for all
employees.

                                   ARTICLE III

                        CONFIDENTIALITY AND NONDISCLOSURE


                  3.1 Confidentiality. Executive shall not, during Executive's
employment by the Company or thereafter, at any time disclose, directly or
indirectly, to any person or entity or use for Executive's own benefit any trade
secrets or confidential information relating to either the Company's or NAC's
business, operations, marketing data, business plans, strategies, employees,
negotiations and contracts with other companies, or any other subject matter
pertaining to the business of either the Company or NAC or any of their
respective clients, customers, consultants, or licensees, known, learned, or
acquired by Executive during the period of Executive's employment by the Company
(collectively "CONFIDENTIAL INFORMATION"), except as may be necessary in the
ordinary course of performing Executive's particular duties as an employee of
the Company.

                  3.2 Return of Confidential Material. Executive shall promptly
deliver to the Company on termination of Executive's employment by the Company,
whether or not for Cause and whatever the reason, or at any time the Company may
so request, all memoranda, notes, records, reports, manuals, drawings,
blueprints, rolodexes, computer files and records, Confidential Information and
any other documents of a confidential nature belonging to either the Company or
NAC, including all copies of such materials which Executive may then possess or
have under Executive's control. Upon termination of Executive's employment by
the Company, Executive shall not take any document, data, or other material of
any nature containing or pertaining to the proprietary information of either the
Company or NAC.

                  3.3 Prohibition on Solicitation of Customers; Noncompetition.
During the term of Executive's employment by the Company, and for a period of
six months thereafter, Executive shall not, directly or indirectly, either for
Executive or for any other person or entity, solicit any person or entity to
terminate such person's or entity's contractual and/or business relationship
with either the Company or NAC, nor shall Executive interfere with or disrupt or
attempt to interfere with or disrupt any such relationship. In addition, for a
period of six months following the term of Executive's employment by the
Company, Executive shall not, directly or indirectly, be engaged (including as a
stockholder, proprietor, general partner, limited partner, trustee, consultant,
employee, director, officer, lender investor or otherwise) in any business or
activity as of the date of termination of employment that is competitive with
that of the Company or any of its subsidiaries activities within the United
States. None of the foregoing shall be deemed a waiver of any and all rights and
remedies the Company may have under applicable law.

                  3.4 Prohibition on Solicitation of Employees, Agents or 
Independent Contractors After Termination. During the term of Executive's
employment by the Company and for a period of six months following the
termination of Executive's



                                        3
<PAGE>   4
employment by the Company, Executive will not solicit any of the employees,
agents, or independent contractors of either the Company or NAC to leave the
employ of the Company or NAC for a competitive company or business. However,
Executive may solicit any employee, agent or independent contractor who
voluntarily terminates his or her employment with either the Company or NAC
after a period of 120 days have elapsed since the termination date of such
employee, agent or independent contractor. None of the foregoing shall be deemed
a waiver of any and all rights and remedies the Company may have under
applicable law.

                  3.5 Right to Injunctive and Equitable Relief. Executive's
obligations not to disclose or use Confidential Information and to refrain from
the solicitations described in this Article III are of a special and unique
character which gives them a peculiar value. The Company cannot be reasonably or
adequately compensated for damages in an action at law in the event Executive
breaches such obligations. Therefore, Executive expressly agrees that the
Company shall be entitled to injunctive and other equitable relief without bond
or other security in the event of such breach in addition to any other rights or
remedies which the Company may possess or be entitled to pursue. Furthermore,
the obligations of Executive and the rights and remedies of the Company under
this Article III are cumulative and in addition to, and not in lieu of, any
obligations, rights, or remedies created by applicable law relating to
misappropriation or theft of trade secrets or Confidential Information.

                  3.6 Survival of Obligations. Executive agrees that the terms
of this Article III and Article V hereof shall survive the term of this
Agreement and the termination of Executive's employment by the Company.


                                   ARTICLE IV

                                   TERMINATION


                  4.1 Definitions.  For purposes of this Article IV, the 
following definitions shall be applicable to the terms set forth below:

                           (a) Cause. "CAUSE" shall mean only the following: (i)
                  failure by the Executive to perform his duties hereunder or
                  those duties which may, from time to time, be reasonably
                  requested by the Board of Directors of the Company (other than
                  such failure resulting from the Executive's incapacity due to
                  physical or mental illness); (ii) misconduct by the Executive
                  which is materially injurious to the Company; (iii) conviction
                  of or pleading no contest to a felony or other crime of moral
                  turpitude; (iv) habitual drunkenness by the Executive; (v)
                  action by the Executive beyond the scope of his employment, as
                  such scope is set by the Board of Directors


                                        4
<PAGE>   5
                  of the Company or NAC from time to time (vi) a material breach
                  of this Agreement by the Executive.

                           (b) Disability. "DISABILITY" shall mean a physical or
                  mental incapacity as a result of which the Executive becomes
                  unable to continue the proper performance of his duties
                  hereunder (reasonable absences because of sickness for up to
                  three (3) consecutive months excepted). A determination of
                  Disability shall be subject to the certification of a
                  qualified medical doctor agreed to by the Company and the
                  Executive or, in the event of the Executive's incapacity to
                  designate a doctor, the Executive's legal representative. In
                  the absence of agreement between the Company and the
                  Executive, each party shall nominate a qualified medical
                  doctor and the two doctors so nominated shall select a third
                  doctor, who shall make the determination as to Disability.

                  4.2 Termination by Company. The Executive's employment
hereunder may be terminated by the Company immediately for Cause. Subject to the
other provisions contained in this Agreement, the Company may terminate this
Agreement for any reason other than Cause upon thirty (30) days' written notice
to Executive. The effective date of termination ("EFFECTIVE DATE") shall be
considered to be thirty (30) days subsequent to written notice of termination;
however, the Company may elect to have Executive leave both the Company and NAC
immediately.

                  4.3      Severance Benefits Received Upon Termination.

                           (a) If at any time the Executive's employment is
                  terminated by the Company for Cause, the Company shall pay the
                  Executive his base salary through the end of the month during
                  which such termination occurs (or at the Executive's election,
                  the rate in effect on the first day of the month preceding the
                  month in which the date of termination occurs) plus credit for
                  any accrued vacation and the Company shall thereafter have no
                  further obligations under this Agreement to the Executive or
                  his or her dependents, beneficiaries or estate; provided,
                  however, that the Company will continue to honor any
                  obligations that may have been accrued under then existing
                  Company Benefit Plans or any other agreements or arrangements
                  applicable to the Executive.

                           (b) If at any time the Executive's employment is
                  terminated by the Company without Cause or as a result of
                  death or Disability, then the Company shall:

                                    (1) pay to the Executive within seven days
                           following the date of termination the pro rata share
                           of his "MONTHLY BASE SALARY" (defined as the result
                           of (i) the Annual Salary divided by (ii) twelve (12))
                           in effect on the date of the termination through the
                           end of the


                                        5
<PAGE>   6
                           month during which such termination occurs, plus 
                           payment for any vacation earned but not taken;

                                    (2) pay to the Executive for termination of
                           his rights hereunder a lump sum, in cash, within
                           seven business days following the date of
                           termination, an amount equal to six months salary
                           based upon the Executive's current Monthly Base
                           Salary; and

                                    (3) provide Executive with such insurance
                           coverage as is then required by COBRA or any similar
                           then applicable law.

                  4.4      No Obligation to Mitigate Damages; No Effect on Other
Contractual Rights.

                           (a) The Executive shall not be required to mitigate
                  damages or the amount of any payment provided for under this
                  Agreement by seeking other employment or otherwise, nor shall
                  the amount of any payment provided for under this Agreement be
                  reduced by any compensation earned by the Executive as the
                  result of employment by another employer after the date of
                  termination, or otherwise.

                           (b) The provisions of this Agreement, and any payment
                  or benefit provided for hereunder, shall not reduce any
                  amounts otherwise payable, or in any way diminish the
                  Executive's existing rights, or rights which would accrue
                  solely as a result of the passage of time, under any Company
                  Benefit Plan, employment agreement or other contract, plan or
                  arrangement.

                           (c) Executive may terminate this Agreement upon 30
                  days written notice to the Company and upon such termination
                  the Company shall make the payment provided for in Section
                  4.3(b)(1) hereof and no further payments shall be required to
                  be made by the Company to Executive.
