                (iii) Fagan's voluntary departure from employment other than for

                (iv) Fagan's termination pursuant to Paragraphs (b) or (c)
                hereof.

                (b) The Board of Directors of Mercury may terminate or shall be
        deemed to have terminated the employment of Fagan at any time:

                (i) "with cause", which is defined herein as Fagan's (1)
                misappropriation of corporate funds, fraud, embezzlement or
                other illegal conduct to the detriment of Mercury, (2)
                negligence in the execution of his material assigned duties, (3)
                refusal or failure, after not less than 20 days written notice
                that such refusal or failure would constitute a default
                hereunder, to carry out any reasonable and material direction
                from the Board of Directors given to him in writing, (4)
                conviction of a felony, (5) material breach or violation of the
                terms of this Agreement, which breach or violation shall not

                in good faith) by Fagan within 20 days after receipt of written
                notice of the same from the Board of Directors, or (6) Fagan's
                engagement in drug or alcohol abuse; or

                (ii) "without cause" if they shall determine that it is in the
                best interests of Mercury to terminate this Agreement for any
                reason other than the reason described in subparagraph (i) of
                this paragraph 6(b).

                (c) In the event, subsequent to a "Change in Control", Fagan and
        Mercury shall jointly determine that the financial prospects of Mercury
        have significantly declined to a level where the future operations of
        Mercury would be impaired, Fagan shall have the right to terminate his
        employment with Mercury by written notice thereof and shall be treated
        as having terminated his employment pursuant to paragraph 6(f) hereof.
        In the event that Fagan and Mercury are unable to agree upon the
        determination pursuant to this paragraph 6(c), an arbitrator, jointly
        selected by the parties, shall resolve the dispute. In the event the
        parties are unable to agree upon an arbitrator, the arbitrator shall be
        selected by two additional arbitrators, one of which shall be an
        arbitrator selected by Mercury and the other of which shall be an
        arbitrator selected by the Fagan.

                (d) In the event Fagan's termination is for any reason set out
        in Paragraphs 6(a)(iii) above prior to a Change in Control or Paragraphs
        6(a)(i) or 6(b)(i) above at any time, Fagan shall not be entitled to any
        termination payments or benefits other than (i) salary and other accrued
        benefits earned up to the date of termination; and (ii) amounts deferred
        pursuant to Paragraph 5(d) hereof. In the event that Fagan asserts that
        his voluntary termination was actually a constructive termination,
        Mercury 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
        Fagan. In the event Fagan's termination is for any reason set out in
        paragraph 6(a)(ii) above prior to a Change in Control, Fagan shall be
        entitled to (i) salary and other accrued benefits earned up to the last
        day of the month of the date of death or Date of Disability (as defined
        in paragraph (g) hereof); (ii) all amounts deferred pursuant to
        paragraph 5(d) hereof and, (iii) a lump sum termination payment equal to
        the highest yearly salary and bonus paid to Fagan pursuant to paragraph
        5(a) in any year during the 3 years immediately subsequent to the year
        in which the death or disability occurs, and, if termination is due to
        disability, Fagan shall also be entitled to the medical, health and
        insurance-related benefits as set forth in paragraph 5(b) hereof prior
        to and for one year following the date of disability.

                (e) For purposes of determining whether a "Change in Control"
        has occurred, a "Change in Control" shall be defined as the occurrence
        at any time during the Contract Term of any of the following events:

                        (1) A change in control of a nature that would have to
                be reported in Mercury's proxy statement filed under the
                Securities Exchange Act of 1934 (the "Exchange Act").

                result of such merger, consolidation or reorganization less than
                75% of the outstanding voting securities or other capital
                interests of the surviving, resulting or acquiring corporation
                or other legal person are owned in the aggregate by the

                        (3) Mercury sells all or substantially all of its

                other capital interests of which are owned in the aggregate by
                the stockholders of Mercury, directly or indirectly, immediately
                prior to or after such sale;

                        (4) Any person (as the term "person" is used in Section
                13 (d) (3) or Section 14(d)(2) of the Exchange Act) has become
                the beneficial owner (as the term "beneficial owner" is defined
                under Rule 13d-3 or any successor rule or regulation promulgated
                under the Exchange Act) of 25% or more of the issued and

                the Directors of Mercury cease for any reason to constitute at

                or election by Mercury's stockholders, of each new Director of
                Mercury was approved by a vote of at least two-thirds of such
                Directors of Mercury then still in office who were Directors of

        personal representative of the estate of Fagan.

                (i) This Section 6 shall not be deemed a limitation of Fagan's
        benefits under any death or disability plan currently in effect.

ventures, parties to cooperative agreements or partners, shall be deemed to be
and shall be confidential information. Fagan hereby confirms that he has not and
shall not, except with the express, prior written consent of Mercury, or except

connection with Mercury's business and in accordance with Mercury's business
practices and employee policies, at any time during or following the term of his
employment by Mercury, directly or indirectly, disclose, divulge, reveal,
report, publish, transfer or use, for any purpose whatsoever, any of such
information which has been obtained by or disclosed to him as a result of his
employment by Mercury. Further, Fagan agrees to be bound by all nondisclosure or
similar covenants between Mercury and any third party.

        9. Fagan further understands that all of the following information and

        quoting procedures, financial information, customer and prospect names
        and requirements, employee, customer supplier and distributor data and
        other materials and information relating to Mercury's business and
        activities and the manner in which Mercury does business;

        d. Discoveries, concepts and ideas including, without limitation, the
        nature and results of research and development activities, processes
        formulas, inventions, computer-related equipment or technology,
        techniques, "know-how", designs, drawings, and specifications;

        e. Any other materials or information related to the business or
        activities of Mercury which are not generally known to others engaged in
        similar businesses or activities;

        f. All ideas which are derived from or relate to Fagan's access to or
        knowledge of any of the above enumerated materials and information; and

        g. All information, data and materials received by Mercury from
        third-parties in confidence (or subject to nondisclosure or similar
        covenants), including but not limited to information, data and materials
        received by Mercury from customers, prospective customers, joint
        ventures, parties to cooperative agreements or partners.

        10. At Mercury's request, or, in the absence of such a request, upon
termination of Fagan's employment with Mercury, Fagan agrees to turn over to
Mercury all notes, data tapes, lists, reference items, sketches drawings
memoranda, records, and other materials in any way relating to any financial
data, Protected Information and Inventions and other documents that are in his
possession or control belonging to Mercury or relating to its business.

        11. Fagan represents and warrants that his employment with Mercury does
not and will not breach any agreement or duty which he has to any other party to
keep in confidence any confidential information belonging to others. Fagan will
not disclose to Mercury or use in its behalf any confidential information
belonging to others. Except as set forth on any exhibit that is attached hereto
and signed by both parties hereof, Fagan does not claim an ownership interest in
any inventions.

        12. Fagan acknowledges that if he were to compete with Mercury in the
aviation services business, it could cause serious harm to Mercury. In the event
that Fagan terminates this Agreement or Mercury terminates this Agreement, Fagan
agrees that he will not engage in the aviation services business for a period of
three (3) years from the time of Fagan's termination of employment within the
Continental United States. This covenant shall survive the termination of this
Agreement and shall apply to any renewal or extension of employment. The
restrictive covenant contained herein shall be given the broadest lawful and
enforceable scope permissible for

                                       6
<PAGE>   7

the protection of Mercury. Fagan has carefully considered his obligations as
stated herein and agrees that the restrictions contained herein are fair and
reasonable and are reasonably required for the protection of Mercury.

        13. Fagan understands that a breach of this Agreement including, but not
limited to, unauthorized copying, assignment, transfer or distribution of
Protected Information and inventions will result in irreparable or immeasurable
damage to Mercury and that Mercury is authorized to seek injunctive relief
against Fagan. Fagan also consents to the exclusive jurisdiction of any federal
or state court located in Los Angeles, California, as the appropriate forum for
resolution of any dispute arising from this Agreement, including issuance of an
injunction. Fagan understands that this provision regarding the issuance of an
injunction does not limit any remedies at law or equity otherwise available to
Mercury.

        14. No oral arrangements have been made between the parties hereto and
this Agreement may he amended only in writing signed by both parties.

        15. The rights and obligations of Mercury under this Agreement shall
inure to the benefit of and shall be binding upon the successors and assigns of
Mercury. Fagan may not assign his obligations under this Agreement.

        16. If any provision of this Agreement shall be declared invalid or
unenforceable by a court of competent jurisdiction, the remainder of this
Agreement shall not be affected thereby and shall continue in full force and
effect.

        17. This Agreement shall be construed in accordance with the laws of the
state of California.

        IN WITNESS WHEREOF, the parties hereto have set their hands and seals as
of the day and year first above written.
