                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT dated as of November 9, 1998 by and
among AMERICAN AIRCARRIERS SUPPORT, INCORPORATED, a Delaware corporation (the
"Company") and CONDOR FLIGHT SPARES, INC. ("Holder").

         The parties agree as follows:

         SECTION 1.     DEFINITIONS.  For purposes of this Agreement:

              (a)    "Common Stock" means the Company's Common Stock, $.001 par
         value;

              (b)    "Registrable Securities" means 125,000 shares of Common
         Stock to be issued to the Holder upon closing of that certain Asset
         Purchase Agreement of even date (the "Agreement"; certain terms not
         defined herein but used herein are used as defined in the Agreement);

              (c)    "register" and "registration" refer to a registration of
         the Registrable Securities effected by filing a registration statement
         or similar document pursuant to the Securities Act of 1933, as amended
         (the "Act") and the declaring or ordering of effectiveness of such
         registration statement; and

              (d)    The "Company" means American Aircarriers Support,
         Incorporated, a Delaware corporation.

              (e)    "Holder" means Condor Flight Spares, Inc. or any
         shareholder thereof who shall receive the shares by permittable
         transfer or assignment.

         SECTION 2.     DEMAND REGISTRATION.

              (a)    If at any time after September 1, 1999 the Company receives
         a written request from the Holder that the Company file a registration
         statement under the Act covering the registration of Registrable
         Securities held by them, then the Company shall, subject to the
         limitations of this Section 2, use its best efforts to, within six
         months of the date of such request, effect the registration under the
         Act of all Registrable Securities and will keep such



   2

         registration statement effective for a minimum period of 12 months
         thereafter. The Company shall be obligated to effect only one (1)
         registration pursuant to this Section 2(a).

              (b)    If the Holder intends to distribute the Registrable
         Securities covered by their request by means of an underwriting, they
         shall so advise the Company as a part of their request made pursuant to
         this Section 2. The Holder shall (together with the Company as provided
         in Section 3) enter into an underwriting agreement in customary form
         with a mutually acceptable underwriter or underwriters.

         SECTION 3.     "PIGGYBACK" RIGHTS. For a period of one (1) year from
November 9, 1998, and if (but without any obligation to do so) the Company
proposes to register any of its securities under the Act in connection with a
public offering of such common stock for cash proceeds payable in whole or in
part to the Company (other than with respect to a Registration Statement filed
on Form S-8 or Form S-4 or such other similar form then in effect under the
Securities Act), the Company shall, at such time, subject to the provisions of
Section 6 and 7 hereof and upon request of the Holder cause to be registered
under the Act all of the Registrable Securities which the Holder requests be
registered; provided, however, if the managing underwriter of the public
offering of shares proposed to be registered by the Company advises the Holder
in writing that marketing factors require a limitation of the number of shares
to be underwritten, then the number of shares of Registrable Securities of the
Holder that may be included in the underwriting shall be so limited prorata.
Such "piggyback rights" shall expire on the registration and sale of the
Registrable Securities pursuant to Section 2 above or upon the sale of the
Registrable Securities hereunder, but in no event later than November 9, 1999.

         SECTION 4.     REGISTRATION PROCEDURE.  Whenever required under
this Agreement to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as is reasonably
possible:

              (a)    Furnish to the Holder of the Registrable Securities covered
         by such registration statement such number of copies of a prospectus,
         including a preliminary prospectus, in conformity with the requirements
         of the Act, and such other documents as they may reasonably request in
         order to facilitate the disposition of the Registrable



   3




         Securities owned by them.

              (b)    In the event of any underwritten public offering, enter
         into and perform its obligations under an underwriting agreement, in
         usual and customary form, with the managing underwriter of such
         offering. The Holder participating in such underwriting shall also
         enter into and perform their obligations under such agreement.

              (c)    Notify the Holder of Registrable Securities covered by such
         registration statement, at any time when a prospectus relating thereto
         covered by such registration statement is required to be delivered
         under the Act, of the happening of any event as a result of which the
         prospectus included in such registration statement, as then in effect,
         includes an untrue statement of a material fact or omits to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in the light of the circumstances
         then existing.

         SECTION 5.     FURNISH INFORMATION. The Holder shall promptly furnish
to the Company in writing such reasonable information regarding the Holder, the
Registrable Securities held by the Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

         SECTION 6.     EXPENSES OF REGISTRATION. All of the foregoing expenses
relating to the Registrable Securities incurred in connection with registration,
filing or qualification pursuant to this Agreement, including (without
limitation) all registration, filing and qualification fees, printers' bills,
mailing and delivery expenses, accounting fees, and the fees and disbursements
of counsel for the Company, but excluding underwriting discounts or fees, shall
be borne by the Company.

         SECTION 7.     INDEMNIFICATION AND CONTRIBUTION.  In the event any
Registrable Securities are included in a registration statement under this
Agreement:

              (a)    To the extent permitted by law, the Company will indemnify
         and hold harmless the Holder, the officers and directors of each
         Holder, any underwriter (as defined in the Act) for such holder, and
         each person, if any, who controls such Holder or underwriter within the
         meaning of the Act or



   4




         the Securities Exchange Act of 1934 (the "Exchange Act"), against any
         losses, claims, damages, or liabilities (joint or several) to which
         they may become subject under the Act, the Exchange Act or other
         federal or state law, insofar as such losses, claims, damages, or
         liabilities (or actions in respect thereto) arise out of or are based
         upon any untrue statement or alleged untrue statement of a material
         fact contained in such registration statement, including any
         preliminary prospectus or final prospectus contained therein or any
         amendments or supplements thereto, or arise out of or are based upon
         the omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading; and the Company will reimburse each such
         Holder, officer or director, underwriter or controlling person for any
         legal or other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability, or
         action; provided however, that the indemnity agreement contained in
         this Section 7(a) shall not apply to amounts paid in settlement of any
         such loss, claim, damage, liability, or action if such settlement is
         effected without the consent of the Company (which consent shall not be
         unreasonably withheld), nor shall the Company be liable in any such
         case for any such loss, claim, damage, liability, or action to the
         extent that it arises out of or is based upon an untrue statement or
         alleged untrue statement or omission or alleged omission made in such
         registration statement, preliminary prospectus or final prospectus or
         any amendment or supplement thereto in reliance upon and in conformity
         with written information furnished expressly for use in connection with
         such registration by any such Holder, underwriter or controlling
         person; provided, further, however, that if any losses, claims, damages
         or liabilities arise out of or are based upon any untrue statement,
         alleged untrue statement, omission or alleged omission contained in any
         preliminary prospectus, and made in reliance upon and in conformity
         with written information furnished by such Holder expressly for use
         therein, which did not appear in the final prospectus, the Company
         shall not have any such liability with respect thereto to such Holder,
         any person who controls such Holder within the meaning of the Act, or
         any director of such Holder, if such Holder delivered a copy of the
         preliminary prospectus to the person alleging such losses, claims,
         damages or liabilities and failed to deliver a copy of the


   5




         final prospectus, as amended or supplemented if it has been amended or
         supplemented, to such person at or prior to the written confirmation of
         the sale to such person, provided that such Holder had an obligation to
         deliver a copy of the final prospectus to such person; and

              (b)    To the extent permitted by law, each selling Holder will
         indemnify and hold harmless the Company, each of its directors, each of
         its officers who has signed the registration statement, each person, if
         any, who controls the Company within the meaning of the Act, any
         underwriter and any other Holder selling securities in such
         registration statement or any of its directors or officers or any
         person who controls such Holder or underwriter against any losses,
         claims, damages or liabilities, joint or several) to which the Company
         or any such director, officers, controlling person, or underwriter or
         controlling person, or other such Holder or director, officer or
         controlling person may become subject, under the Act, the Exchange Act
         or other federal or state law, insofar as such losses, claims, damages
         or liabilities (or actions in respect thereto) arise out of or are
         based upon any untrue statement or alleged untrue statement of a
         material fact contained in such registration statement, including any
         preliminary prospectus or final prospectus contained therein or any
         amendments or supplements thereto, or arise out of or are based upon
         the omission or alleged omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, if the untrue statement or omission or alleged
         untrue statement or omission in respect of which such loss, claim,
         damage or liability is asserted was made in reliance upon and in
         conformity with written information furnished by such Holder expressly
         for use in connection with such registration; and each such Holder will
         reimburse any legal or other expenses reasonably incurred by the
         Company or any such director, officer, controlling person, underwriter
         or controlling person, or other Holder, officer, director, or
         controlling person in connection with investigating or defending any
         such loss, claim, damage, liability or action; provided however, that
         the indemnity agreement contained in this Section 7(b) shall not apply
         to amounts paid in settlement of any such loss, claim, damage,
         liability or action, if such settlement is effected without the consent
         of the Holder (which consent shall not be unreasonably withheld);
         provided, further that



   6




         the maximum liability of any selling Holder under this Section 7(b) in
         regard to any registration statement shall in no event exceed the
         amount of the proceeds received by such selling Holder from the sale of
         securities under such registration statement; provided, further
         however, that if any losses, claims, damages or liabilities arise out
         of or are based upon an untrue statement, alleged untrue statement,
         omission or alleged omission contained in any preliminary prospectus
         which did not appear in the final prospectus, such seller shall not
         have any such liability with respect thereto to the Company, any person
         who controls the Company within the meaning of the Act, any officer of
         the Company who signed the registration statement or any director of
         the Company, if the Company delivered a copy of the preliminary
         prospectus to the person alleging such losses, claims, damages or
         liabilities and failed to deliver a copy of the final prospectus, as
         amended or supplemented if it has been amended or supplemented, to such
         person at or prior to the written confirmation of the sale to such
         person, provided that the Company had an obligation to deliver a copy
         of the final prospectus to such person.

              (c)    Promptly after receipt by an indemnified party under this
         Section 7 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under this
         Section 7, deliver to the indemnifying party a written notice of the
         commencement thereof, and the indemnifying party shall have the right
         to participate in and, to the extent the indemnifying party so desires,
         jointly with any other indemnifying party similarly notified, to assume
         the defense thereof with counsel mutually satisfactory to the parties.
         An indemnified party shall have the right to retain its own counsel,
         however, the fees and expenses of such counsel shall be at the expense
         of the indemnified party, unless (i) the employment of such counsel has
         been specifically authorized in writing by the indemnifying party, (ii)
         the indemnifying party has failed to assume the defense and employ
         counsel, or (iii) the named parties to any such action (including any
         impleaded parties) include both the indemnified party and the
         indemnifying party, and the indemnified party shall have been advised
         by such counsel that there may be one or more legal defenses available
         to it which are different from or additional to those available to



   7




         the indemnifying party (in which case the indemnifying party shall not
         have the right to assume the defense of such action on behalf of such
         indemnified parry, it being understood, however, that the indemnifying
         party shall not, in connection with any one such action or separate but
         substantially similar or related actions in the same jurisdiction
         arising out of the same general allegations or circumstances, be liable
         for the reasonable fees and expenses of more than one separate firm of
         attorneys for all indemnified parties). The failure to deliver written
         notice to the indemnifying party will not relieve it of any liability
         that it may have to any indemnified party under this Agreement.

              (d)    If the indemnification provided for in this Section 7 is
         unavailable or insufficient to hold harmless an indemnified party in
         respect of any losses, claims, damages or liabilities or actions in
         respect thereof referred to therein, then each indemnifying party shall
         in lieu of; indemnifying such indemnified party contribute to the
         amount paid or payable by such indemnified party as a result of such
         losses, claims, damages, liabilities or actions in such proportion as
         is appropriate to reflect the relative fault of the Company, on the one
         hand, and selling Holder, on the other, in connection with the
         statements or omissions which resulted in such losses, claims, damages,
         liabilities or actions as well as any other relevant equitable
         considerations, including the failure to give any required notice. The
         relative fault shall be determined by reference to, among other things,
         whether the untrue or alleged untrue statement of a material fact or
         the omission or alleged omission to state a material fact relates to
         information supplied by the Company, on the one hand, or by such
         selling Holder on the other, and the parties' relative intent,
         knowledge, access to information and opportunity to correct or prevent
         such statement or omission. The parties hereto acknowledge and agree
         that it would not be just and equitable if contribution pursuant to
         this subparagraph (d) were determined by prorata allocation (even if
         all of the selling Holder were treated as one entity for such purpose)
         or by any other method of allocation which does not take account of the
         equitable considerations referred to above in this subparagraph (d).
         The amount paid or payable by an indemnified party as a result of the
         losses, claims, damages, liabilities or actions in respect thereof
         referred



   8




         to above in this subparagraph (d) shall be deemed to include any legal
         or other expenses reasonably incurred by such indemnified party in
         connection with investigating or defending any such action or claim.
         Notwithstanding the provisions of this subparagraph (d), the amount the
         selling Holder shall be required to contribute shall not exceed the
         amount, if any, by which the total price at which the securities sold
         by each of them were offered to the public exceeds the amount of any
         damages which they would have otherwise been required to pay by reason
         of such untrue or alleged untrue statement or omission or alleged
         omission, or other violation of law. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the Act)
         shall be entitled to contribution from any person who was not guilty of
         fraudulent misrepresentation

         SECTION 8.     MISCELLANEOUS.

              (a)    Binding Effect. This Agreement shall be binding upon and
         shall inure to the benefit of the Company and to the Holder and their
         respective heirs, personal representatives, successors and assigns.

         consent or request to be given in connection with any term or provision
         of this Agreement shall be deemed to have been given sufficiently if
         sent by hand, registered or certified mail, postage prepaid, facsimile
         transmission or courier (next day delivery), to the Company or to the
         Holder at their respective addresses as provided on or about the date
         hereof.

              (c)    Integration. This Agreement contains the entire agreement
         between the parties with respect to the transactions contemplated
         hereby and no party shall be bound by, nor shall any party be deemed to
         have made, any covenants, representations, warranties undertakings or
         agreements except those contained in such entire Agreement. The section
         and paragraph headings contained in this Agreement are for the
         reference purposes only and shall not affect in any way the meaning or
         interpretation of this Agreement.

              (d)    Counterparts. This Agreement may be executed in one or more
         counterparts, each of which shall be deemed to



   9



         be an original, but all of which together shall constitute
         one and the same agreement.

              (e)    Amendment. This Agreement may be amended, changed, waived
         or terminated only in writing signed by each of the parties.


         IN WITNESS WHEREOf, this Agreement has been executed effective as of
the date first above written.
