                          WAIVER AND SIXTH AMENDMENT TO
                           LOAN AND SECURITY AGREEMENT

         THIS WAIVER AND SIXTH AMENDMENT TO LOAN AND SECURITY Agreement (this
"Amendment") is made and entered into as of the 7th day of August, 2000, by and
among BANK OF AMERICA, N.A., formerly NationsBank, N.A., as agent (the "Agent")
for the lenders (the "Lenders") from time to time party to the Loan Agreement
(as hereafter defined), the Lenders, AMERICAN AIRCARRIERS SUPPORT, INCORPORATED,
a Delaware corporation ("AAS"), and the Subsidiaries of AAS party to the Loan
Agreement as borrowers (together with AAS, the "Borrowers").

                              W I T N E S S E T H :

         WHEREAS, the Agent, the Lenders and the Borrowers entered into that
certain Loan and Security Agreement, dated as of May 25, 1999 (as amended from
time to time, the "Loan Agreement"), pursuant to which the Agent and the Lenders
agreed to extend certain financial accommodations to the Borrowers; and

         WHEREAS, pursuant to the Loan Agreement, the Borrowers agreed, among
other things, to maintain the outstanding loan balance within a borrowing base
and to comply with certain minimum availability and financial covenants; and

         WHEREAS, the Borrowers have allowed the outstanding loan balance to
exceed the borrowing base and have violated and continue to violate the minimum
availability and financial covenants set forth in the Loan Agreement; and

         WHEREAS, the Borrowers' agreements to maintain the outstanding loan
balance within a borrowing base, and to comply with certain minimum availability
and financial covenants, were material inducements to the Agent's and the
Lenders' agreement to enter into the Loan Agreement, and the Lenders would not
have agreed to make loans available to the Borrowers without the assurance that
the Borrowers would comply with such agreements; and

         WHEREAS, the Borrowers requested that the Agent and the Lenders forbear
from exercising their rights and remedies with respect to such defaults; and

         WHEREAS, the Borrowers, the Agent and the Lenders entered into that
certain Fifth Amendment and Forbearance Agreement dated as of June 22, 2000 (the
"Forbearance

<PAGE>   2

Agreement"), pursuant to which the Agent and the Lenders agreed, subject to the
terms and conditions set forth therein, to forbear from exercising their rights
and remedies for a limited period of time; and

         WHEREAS, the forbearance period set forth in the Forbearance Agreement
has expired, and the Borrowers have been unable to cure such defaults; and

         WHEREAS, as a result of such expiration, the Agent and the Lenders have
the right, as set forth in the Loan Agreement and the other Loan Documents, to
immediately accelerate all of the Secured Obligations and exercise all of their
rights and remedies with respect to the Collateral, all without notice to the
Borrowers; and

         WHEREAS, the Borrowers have requested that the Agent and the Lenders
waive such defaults and amend the Loan Agreement on the terms and conditions set
forth herein; and

         WHEREAS, the Agent and the Lenders are willing to grant such waivers
and amend the Loan Agreement, subject to the terms and conditions set forth
herein.

         NOW, THEREFORE, in consideration of the foregoing premises, and other
good and valuable consideration, the receipt and legal sufficiency of which are
hereby acknowledged, the parties hereto hereby agree as follows:

         1. All capitalized terms used herein and not otherwise expressly
defined herein shall have the respective meanings given to such terms in the
Loan Agreement.

         2. The Borrowers acknowledge that they are in default under (a) SECTION
2A.3(B) of the Loan Agreement, for periods up to and including the date hereof,
as a result of the fact that the unpaid principal amount of the Revolving Credit
Loans has exceeded, and continues to exceed, the Borrowing Base, (b) SECTION
11.1(B) of the Loan Agreement for the fiscal quarter ending on June 30, 2000, as
a result of the Borrowers' failure to maintain the Consolidated Funded
Indebtedness to Consolidated EBITDA ratio set forth therein, (c) SECTION 11.1(C)
of the Loan Agreement for the fiscal quarter ending on June 30, 2000, as a
result of the Borrowers' failure to maintain the Consolidated fixed charge
coverage ratio set forth therein, (d) SECTION 11.5 of the Loan Agreement for
fiscal year 2000, as a result of the Borrowers' failure to comply with the
Capital Expenditure limit set forth therein, and (e) SECTION 11.17 of the Loan
Agreement for periods up to and including the date hereof, as a result of the
Borrowers' failure to comply with the minimum Availability covenant set forth
therein (collectively, the "Specified Defaults"). The Borrowers acknowledge
that, because of the Specified Defaults, the Agent and the Lenders have the
right, among other things, to declare all of the Secured Obligations to be
immediately due, payable and performable, and to enforce collection of the
Secured Obligations by repossessing and disposing of any interest in the
Collateral thereunder, as more fully set forth in ARTICLE 12 of the Loan
Agreement. In consideration of the Borrowers' timely and strict compliance with
their agreements set forth in the Loan Agreement, and in reliance upon the
representations, warranties, agreements and covenants of the Borrowers set forth
herein and in the Loan Agreement, as amended hereby, the Agent and the Lenders
hereby waive the Specified Defaults. Notwithstanding the foregoing, the Agent
and the

                                      -2-

Lenders reserve their rights and remedies at all times with respect to any
Default or Event of Default under the Loan Agreement or this Amendment other
than a Specified Default, whether presently existing or occurring hereafter.

         3. To induce the Agent and the Lenders to enter into this Amendment and
grant the accommodations set forth herein, the Borrowers agree with the Agent
and the Lenders as follows:

                  (a) Until the Required Lenders otherwise consent in writing,
         the Borrowers shall provide to the Agent and the Lenders a Borrowing
         Base Certificate on each Business Day, prepared as of the close of
         business on the immediately preceding Business Day to reflect
         information with respect to Receivables (including, without limitation,
         sales and collections) as of such immediately preceding Business Day;
         provided, however, that information on such Borrowing Base Certificates
         with respect to Inventory shall only be required to be updated as of
         the close of business on the last Business Day of each calendar month
         within fifteen Business Days of the end of such calendar month.

                  (b) Until Availability first equals or exceeds $1,000,000
         after the date hereof, the Borrowers shall have no right to request or
         receive, and the Lenders shall have no obligation to make, any LIBOR
         Rate Loans (nor shall any existing Loan be converted to or continued as
         a LIBOR Rate Loan) or Capital Expenditure Loans.

                  (c) Until Availability first equals or exceeds $1,000,000
         after the date hereof, each Borrower agrees that it shall not return
         $50,000 (based on such Borrower's cost therefor) or more of Inventory
         to any vendor for any reason without the prior written consent of the
         Agent and the Lenders.

                  (d) Until Availability first equals or exceeds $1,000,000
         after the date hereof, no Receivable included in any Borrowing Base
         Certificate on or after the date hereof in excess of $250,000 shall
         constitute an Eligible Receivable until approved by the Agent. For each
         such Receivable, the Borrowers shall provide the Agent with true and
         complete copies of the invoice and purchase order with respect thereto
         (such copies to be sent to the attention of both Byron Turner and John
         Bohan (facsimile number 404-607-6437)). With respect to any Receivable
         that is not approved by the Agent pursuant to this paragraph, the Agent
         agrees to notify the Borrowers' Agent of such disapproval on the
         Business Day following the actual receipt by the Agent of the
         applicable invoice and purchase order for such Receivable and, if such
         notification is not sent to the Borrowers' Agent on such following
         Business Day, and such Receivable would otherwise constitute an
         Eligible Receivable, such Receivable shall be included in the Borrowing
         Base.

                  (e) It shall constitute an immediate Event of Default if AAS
         does not receive, following the date hereof, at least $1,000,000 of
         equity by August 15, 2000 (such equity is hereafter referred to as the
         "Initial Equity Investment") on terms and conditions (including all
         applicable legal documents) acceptable to the Agent and the Lenders in
         their discretion.

                                      -3-

<PAGE>   4

                  (f) It shall constitute an immediate Event of Default if AAS
         does not receive, following the date hereof and in addition to the
         Initial Equity Investment, at least $5,000,000 of equity by August 31,
         2000 (such equity is hereafter referred to as the "Secondary Equity
         Investment") on terms and conditions (including all applicable legal
         documents) acceptable to the Agent and the Lenders in their discretion.

                  (g) It shall constitute an immediate Event of Default if AAS
         does not receive, following the date hereof and in addition to the
         Initial Equity Investment and the Secondary Equity Investment, at least
         $10,000,000 of equity or Subordinated Indebtedness by September 30,
         2000 (such equity or Subordinated Indebtedness is hereafter referred to
         as the "Subordinated Indebtedness Investment"; the Initial Equity
         Investment, the Secondary Equity Investment and the Subordinated
         Indebtedness Investment are sometimes collectively referred to as the
         "Additional Capital") on terms and conditions (including all applicable
         legal documents) acceptable to the Agent and the Lenders in their
         discretion.

                  (h) The proceeds from the Additional Capital described above,
         together with the proceeds of any Asset Disposition with respect to the
         stock or assets of AAS Aircraft Services, Inc. ("Aircraft Services";
         any such Asset Disposition with respect to Aircraft Services is
         sometimes referred to herein as an "Aircraft Services Disposition"),
         shall be applied by the Borrowers to the partial repayment of the
         then-outstanding Secured Obligations as provided in SECTION 4.9 of the
         Loan Agreement; provided, however, that (i) the proceeds from the
         Additional Capital shall be applied to the Secured Obligations on the
         date such proceeds are received by the Borrowers; and (ii) (A) with
         respect to the Additional Capital, such proceeds shall be applied first
         to the outstanding Revolving Credit Loans to the extent thereof and
         then to Capital Expenditure Loans to the extent thereof, and (B) with
         respect to any Aircraft Services Disposition, the first $1,425,000 of
         such proceeds shall be applied to the outstanding Capital Expenditure
         Loans made to finance assets of Aircraft Services and then to the
         outstanding Revolving Credit Loans to the extent thereof. Nothing
         contained in this paragraph shall be construed to permit any Borrower
         to consummate any Asset Disposition or other merger, consolidation or
         asset sale (other than sales and leases of Inventory in the ordinary
         course of business) without the prior written consent of the Required
         Lenders.

                  (i) Notwithstanding anything to the contrary set forth in any
         of the Loan Documents, the Borrowers shall not cause or permit an
         Overadvance in excess of $7,200,000 to exist during the period from the
         date hereof to and including the earlier of September 30, 2000, and the
         occurrence of a Default or Event of Default (it being understood that,
         upon the occurrence of any Default or Event of Default prior to
         September 30, 2000, the Borrowers shall be required to immediately and
         permanently reduce all Overadvances to zero); provided, however, that
         the Overadvance limit set forth above shall be immediately and
         permanently reduced (and, upon the elimination of the Overadvances, the
         minimum Availability which the Borrowers are required to maintain shall
         be increased but shall not exceed $1,000,000) by an amount equal to (i)
         70% of the

                                      -4-

<PAGE>   5

         proceeds from the Secondary Equity Investment on the date of receipt by
         AAS thereof; (ii) 100% of the proceeds of the Subordinated Indebtedness
         Investment on the date of the funding thereof; and (iii) 100% of the
         amount applied to the Revolving Credit Loans as the result of the
         receipt of the proceeds from an Aircraft Services Disposition;
         provided, further, that the Lenders shall not be obligated to make any
         Loan to the Borrowers if the making of such Loan would create an
         Overadvance in excess of $7,000,000, it being understood that the Agent
         intends to fund any Overadvance between $7,000,000 and $7,200,000 as an
         Agent Advance under SECTION 4.7(D)(II) of the Loan Agreement. (By way
         of example, if, on August 20, 2000, Overadvances equal $7,200,000 and
         the Borrowers receive the Secondary Equity Investment in an amount of
         $5,000,000, the Overadvance limit would decrease to $3,700,000
         ($7,200,000 minus 70% of $5,000,000). If the Subordinated Indebtedness
         Investment were then funded on September 15, 2000, in the amount of
         $10,000,000, the Overadvance limit would decrease to zero and the
         Borrowers would be required to maintain Availability of at least
         $1,000,000 thereafter.) From and after the earlier of October 1, 2000
         and the first date on which Availability equals or exceeds $1,000,000,
         the Borrowers shall be required to comply with the $1,000,000 minimum
         Availability covenant set forth in SECTION 11.17 of the Loan Agreement.
         As used herein, "Overadvance" shall mean, as of any date of
         determination, the amount by which the outstanding principal balance of
         Revolving Credit Loans exceeds the Borrowing Base. In the event an
         Overadvance exists at any time in excess of the applicable limit, the
         Agent and the Lenders may immediately exercise all of their rights and
         remedies under the Loan Documents as a result thereof.

                  (j) If the Borrowers fail to obtain any portion of the
         Additional Capital by the applicable date required by paragraphs (e),
         (f) and (g) above, or if the Borrowers fail to reduce the Overadvances
         or maintain the minimum Availability as required by paragraph (i)
         above, the Borrowers shall (i) within thirteen (13) Business Days of
         any such failure, engage a liquidation consultant reasonably acceptable
         to the Agent, and (ii) within twenty-two (22) Business Days of any such
         failure, deliver to the Agent and the Lenders the written report and
         recommendations, in scope and detail reasonably satisfactory to the
         Agent and the Lenders, of such liquidation consultant. The engagement
         of such consultant and the delivery of such report shall be in addition
         to, and shall not limit in any way, any other rights and remedies of
         the Agent and the Lenders with respect to any Event of Default under
         paragraphs (e), (f), (g) and (i) above.

                  (k) Until Availability first equals or exceeds $1,000,000
         after the date hereof, the Borrowers, the Lenders and the Agent agree
         that the Agent Advances under SECTION 4.7(D)(II) of the Loan Agreement
         shall not exceed $200,000 at any one time outstanding.

                  (l) No payment shall be made by AAS Technologies or any other
         Borrower with respect to the AAS Technologies Indebtedness, nor shall
         any Investment be made in AAS Technologies by any of the other
         Borrowers for the purpose of repaying any of the AAS Technologies
         Indebtedness, unless after giving effect to such payment the Borrowers
         are in compliance with all of the terms and conditions of the Loan
         Agreement, including without limitation, (i) the $1,000,000 minimum
         Availability requirement set

                                      -5-

<PAGE>   6

         forth in SECTION 11.17 of the Loan Agreement, and (ii) the financial
         covenants set forth in SECTION 11.1 of the Loan Agreement; provided,
         however, so long as no Event of Default exists or would be caused
         thereby, AAS Technologies may make regularly scheduled interest
         payments at the non-default contract rate on the AAS Technologies
         Indebtedness.

                  (m) Until Availability first equals or exceeds $1,000,000
         after the date hereof, the Borrowers shall provide to the Agent, by the
         third Business Day of each week as of the close of business on the last
         Business Day of the immediately preceding week, a contra report, in
         form acceptable to the Agent, disclosing all Account Debtors to which
         any Borrower owes any Indebtedness and the amounts owing by such
         Account Debtors to the Borrowers and by the Borrowers to such Account
         Debtors.

                  (n) The terms, conditions and provisions set forth in this
         paragraph 3 may not be amended, modified or waived without the written
         agreement of the Borrowers, the Agent and the Lenders.

                  (o) Any failure by any Borrower to comply with any of the
         terms and conditions of any part of this paragraph 3 shall constitute
         an immediate Event of Default.

         4. The Loan Agreement is hereby amended by deleting all references to
"NationsBank, N.A." and substituting "Bank of America, N.A." in lieu thereof,
and by deleting all references to "NationsBank" and substituting "Bank of
America" in lieu thereof.

         5. The Loan Agreement is hereby amended by deleting the definitions of
"Borrowing Base" and "Revolving Credit Facility" set forth in SECTION 1.1 and
substituting the following in lieu thereof:

         "Borrowing Base" means at any time an amount equal to the lesser of:

         (a) the Revolving Credit Facility MINUS the sum of

                  (i) the Letter of Credit Reserve, PLUS

                  (ii) such other reserves as the Agent in its reasonable
         judgment may establish from time to time in accordance with customary
         asset-based lending practices, and

         (b) an amount equal to

                  (i) 80% of the face value of the Eligible Domestic Receivables
         due and owing to the Borrowers at such time, PLUS

                  (ii) the lesser of

                                      -6-

<PAGE>   7

                           (A) 75% of the face value of the Eligible Foreign
                  Receivables due and owing to the Borrowers at such time, AND

                           (B) $5,000,000;

                  provided, however, the amount available under clause (b)(ii)
                  shall in no event exceed 50% of the total amount under clause
                  (b) above, PLUS

                  (iii) 60% of the Orderly Liquidation Value of the Eligible
         Parts Inventory of the Borrowers at such time, PLUS

                  (iv) 85% of the Orderly Liquidation Value of the Eligible
         Inventoried Engine Inventory of the Borrowers at such time, PLUS

                  (v) 85% of the Orderly Liquidation Value of Eligible Domestic
         Leased Engine Inventory of the Borrowers at such time, provided that
         the Orderly Liquidation Value of any item of Eligible Domestic Leased
         Engine Inventory included in the Borrowing Base shall be limited to the
         Lease Present Value of the Lease Agreement to which such Inventory is
         subject, PLUS

                  (vi) the lesser of

                           (A) 85% of the Orderly Liquidation Value of Eligible
                  Foreign Leased Engine Inventory of the Borrowers at such time,
                  provided that the Orderly Liquidation Value of any item of
                  Eligible Foreign Leased Engine Inventory included in the
                  Borrowing Base shall be limited to the Lease Present Value of
                  the Lease Agreement to which such Inventory is subject, AND

                           (B) $5,000,000;

                  provided, however, in any event, the dollar amount included in
                  the Borrowing Base under clauses (v) and (vi) above shall at
                  no time exceed in the aggregate $25,000,000 minus all Special
                  Purpose Subsidiary Indebtedness outstanding at such time;
                  provided, further, in any event, the dollar amount included in
                  the Borrowing Base under clauses (iii), (iv), (v) and (vi)
                  above shall at no time exceed (1) from August 1, 2000 through
                  and including September 30, 2000, $61,000,000 in the
                  aggregate; or (2) from and after October 1, 2000, $60,000,000,
                  MINUS

                                      -7-

<PAGE>   8

                           (B) such other reserves as the Agent in its
                  reasonable judgment may establish from time to time in
                  accordance with customary asset-based lending practices.

                  The Borrowing Base shall be adjusted upon the sale of (i) any
                  Eligible Parts Inventory (if the net book value of the Parts
                  Inventory sold exceeds $250,000 per transaction), and (ii) any
                  Eligible Engine Inventory, by removing the net book value of
                  the Parts Inventory from the Borrowing Base and removing the
                  Orderly Liquidation Value of the Engine Inventory from the
                  Borrowing Base at the earlier to occur of (i) the time the
                  Agent delivers to the Borrowers the instrument releasing such
                  Inventory from the Security Interest, or (ii) the time the
                  Borrowers transfer title to such item of Inventory. The
                  Borrowers shall deliver to the Agent a revised Borrowing Base
                  Certificate within 5 Business Days of the earlier to occur of
                  (i) or (ii), above.

                  Notwithstanding the fact that an Orderly Liquidation Value
                  appraisal for such Inventory has not yet been completed and
                  received by the Agent in accordance with SECTION 8.12(F), upon
                  the Borrowers' request and, with respect to Bulk Purchases, at
                  the discretion of the Agent, and provided all other conditions
                  to eligibility have been met, the Borrowing Base shall be
                  adjusted following the acquisition by any Borrower of Engine
                  Inventory or Parts Inventory (if such acquisition was in
                  connection with a Bulk Purchase) in connection with (i) the
                  purchase of such Inventory in the ordinary course of business,
                  (ii) a Permitted Acquisition, or (iii) an Acquisition
                  expressly permitted by the Required Lenders. The Borrowers
                  shall provide the Agent with such information regarding any
                  such Inventory to enable the Agent to determine whether such
                  Inventory is eligible for inclusion in the Borrowing Base.
                  Such adjustment to the Borrowing Base shall be effected by the
                  Borrowers providing to the Agent an updated Borrowing Base
                  Certificate specifying the Eligible Parts Inventory and the
                  Eligible Engine Inventory acquired by the Borrowers pursuant
                  to such Bulk Purchase and including in the Borrowing Base
                  either (i) 60% of the Borrowers' cost (as evidenced by the
                  invoice therefor) for such Eligible Parts Inventory, or (ii)
                  70% of the Borrowers' cost (as evidenced by the invoice
                  therefor) for such Eligible Engine Inventory.

                  In addition, at the Agent's discretion, if an Orderly
                  Liquidation Value appraisal for such Inventory has been
                  completed and received by the Agent in accordance with SECTION
                  8.12(F), upon the Borrowers' request and provided all
                  conditions to eligibility have been met, the Borrowing Base
                  shall be adjusted to reflect intra-month acquisitions of
                  Eligible Parts Inventory and Eligible Engine Inventory
                  acquired in connection with Bulk Purchases. Such adjustment to
                  the Borrowing Base shall be effected by

                                      -8-

<PAGE>   9

                  the Borrowers providing to the Agent an updated Borrowing Base
                  Certificate specifying the Eligible Parts Inventory and the
                  Eligible Engine Inventory acquired by the Borrowers pursuant
                  to such Bulk Purchase. The Borrowing Base shall also be
                  adjusted on a monthly basis, based on the Orderly Liquidation
                  Value appraisals delivered under SECTION 8.12(F).
                  Notwithstanding anything to the contrary contained herein,
                  Inventory acquired in connection with a Bulk Purchase shall be
                  eligible for inclusion in the Borrowing Base (subject to the
                  conditions set forth in this paragraph and in the preceding
                  paragraph) only at the Agent's discretion, for all Bulk
                  Purchases with purchase prices of not more than $4,000,000 per
                  Bulk Purchase, and only with the consent of the Required
                  Lenders, for all Bulk Purchases with purchase prices of
                  $4,000,000 or greater per Bulk Purchase.

                  Notwithstanding the foregoing, no Receivables acquired in
                  connection with a Permitted Acquisition shall be eligible for
                  inclusion in the Borrowing Base until such time as a field
                  examination has been completed by the Agent or its designee
                  with respect to the Receivables acquired.

                  Upon the request of the Borrowers, the Lenders will in their
                  discretion consider including in the Borrowing Base certain
                  Parts Inventory and aircraft leased by a Borrower to an
                  Account Debtor. Establishment of advance rates and eligibility
                  definitions for such leased Collateral, as well as the
                  decision regarding whether to include such leased Collateral
                  in the Borrowing Base at all, shall be made by the Lenders in
                  their discretion. Any Parts Inventory or aircraft leased by a
                  Borrower to an Account Debtor and determined by the Lenders to
                  be eligible for inclusion in the Borrowing Base shall
                  nonetheless be subject to the limit set forth in the proviso
                  following clause (vi) above.

                  "Revolving Credit Facility" means the principal amount of
         $85,000,000 or such lesser or greater amount as shall be agreed upon
         from time to time in writing by the Agent, the Lenders and the
         Borrowers.

         6. The Loan Agreement is hereby amended by deleting the reference to
"$100,000,000" in SECTION 2B.1(A)(II) and substituting "$85,000,000".

         7. The Loan Agreement is hereby amended by deleting SECTION 11.1 and
substituting the following in lieu thereof:

                  SECTION 11.1 Financial Ratios.

                  (a) Minimum Consolidated Tangible Net Worth. Permit the
         Consolidated Tangible Net Worth of the Borrowers and their Consolidated
         Subsidiaries, measured at the end of the 2000 fiscal year, to be less
         than

                                      -9-

<PAGE>   10

         $15,000,000; for each subsequent fiscal year end, the required Minimum
         Consolidated Tangible Net Worth shall be increased by the greater of
         (i) 75% of the Consolidated positive Net Income of the Borrowers and
         their Consolidated Subsidiaries for the previous fiscal year, or (ii)
         $2,500,000.

                  (b) Maximum Consolidated Funded Indebtedness to Consolidated
         EBITDA Ratio. Permit the ratio of the Consolidated Funded Indebtedness
         of the Borrowers and their Consolidated Subsidiaries as of any fiscal
         quarter end, to the Consolidated EBITDA of the Borrowers and their
         Consolidated Subsidiaries for the preceding four fiscal quarters, to be
         greater than 5.0 to 1 for any quarter, commencing with the fiscal
         quarter ending March 31, 2001.

                  (c) Minimum Consolidated Fixed Charge Coverage Ratio. Permit
         the ratio of (i) the Consolidated EBITDA of the Borrowers and their
         Consolidated Subsidiaries other than any Special Purpose Subsidiaries,
         minus Unfunded Capital Expenditures, dividends and cash taxes paid by
         the Borrowers and their Consolidated Subsidiaries other than any
         Special Purpose Subsidiaries, to (ii) the Consolidated Fixed Charges of
         the Borrowers and their Consolidated Subsidiaries other than any
         Special Purpose Subsidiaries, to be less than 2.0 to 1 as of the fiscal
         quarter ending March 31, 2001 and as of any fiscal quarter ending
         thereafter, measured for the immediately preceding four fiscal
         quarters.

         8. The Loan Agreement is hereby amended by deleting SECTION 11.5 and
substituting the following in lieu thereof:

                  SECTION 11.5 Capital Expenditures. Make or incur any Capital
         Expenditures, except that the Borrowers and their Subsidiaries may make
         or incur Capital Expenditures in the 2000 fiscal year in an amount not
         to exceed, in the aggregate, $6,200,000, and the Borrowers and their
         Subsidiaries may make or incur Capital Expenditures in any subsequent
         fiscal year in an amount not to exceed, in the aggregate for any such
         fiscal year, $2,500,000.

         9. The Loan Agreement is hereby amended by deleting ANNEX II and
substituting the ANNEX II attached hereto in lieu thereof.

         10. The Borrowers have previously executed and delivered a Revolving
Credit Note and a Capital Expenditure Note in favor of each Lender. In order to
reflect the decrease in the Revolving Credit Facility as set forth in this
Amendment, the principal face amount of the Revolving Credit Note in favor of
each Lender is hereby amended as set forth below:

      Total:                                          $85,000,000

         11. The Borrowers, the Lenders and the Agent each hereby acknowledge
and agree that, pursuant to the amendments to the Loan Agreement set forth in
the Forbearance Agreement, the first scheduled principal repayment with respect
to the Capital Expenditure Loans shall be due on October 1, 2000. The previous
sentence constitutes only a clarification, and the failure to restate any other
amendments previously made the Loan Agreement, in the Forbearance Agreement or
otherwise, shall not be construed as an indication that such amendments are no
longer in full force and effect.

         12. The Borrowers agree to pay on demand all costs and expenses of the
Agent and the Lenders in connection with the preparation, execution and delivery
of this Amendment, including, without limitation, the reasonable fees and
out-of-pocket expenses of legal counsel to the Agent and the Lenders. The
Borrowers authorize the Agent to charge the Borrowers' Loan Account for such
fees and expenses.

         13. To induce the Agent and each Lender to enter into this Amendment,
the Borrowers hereby represent and warrant that, as of the date hereof, and
after giving effect to the terms hereof, there exists no Default or Event of
Default.

         14. The Borrowers hereby restate, ratify, and reaffirm each and every
term, condition, representation and warranty heretofore made by each of them
under or in connection with the execution and delivery of the Loan Agreement and
the other Loan Documents, as fully as though such representations and warranties
had been made on the date hereof and with specific reference to this Amendment,
except to the extent that any such representation or warranty relates solely to
a prior date.

         15. Except as expressly set forth herein, the Loan Agreement and the
other Loan Documents shall be and remain in full force and effect as originally
written, and shall constitute the legal, valid, binding and enforceable
obligations of the Borrowers to the Agent and the Lenders.

         16. To induce the Agent and the Lenders to enter into this Amendment
and grant the accommodations set forth herein, each Borrower agrees that (a)
except as expressly set forth herein, neither the Agent nor any Lender has
agreed to (and has no obligation whatsoever to discuss, negotiate or agree to)
any other restructuring, modification, amendment, waiver or forbearance with
respect to the Secured Obligations or the Loan Agreement, (b) no understanding
with respect to any

                                      -11-

<PAGE>   12

other restructuring, modification, amendment, waiver or forbearance with respect
to the Secured Obligations or the Loan Agreement shall constitute a legally
binding agreement or contract, or have any force or effect whatsoever, unless
and until reduced to writing and signed by authorized representatives of each
party hereto, and (c) the execution and delivery of this Amendment has not
established any course of dealing between the parties hereto or created any
obligation or agreement of the Agent or any Lender with respect to any future
restructuring, modification, amendment, waiver or forbearance with respect to
the Secured Obligations or the Loan Agreement.

         17. To induce the Agent and the Lenders to enter into this Amendment
and grant the accommodations set forth herein, each Borrower (a) acknowledges
and agrees that no right of offset, defense, counterclaim, claim or objection
exists in favor of such Borrower against the Agent or any Lender arising out of
or with respect to the Loan Agreement, the other Loan Documents, the Secured
Obligations, or any other arrangement or relationship between the Agent, any
Lender and such Borrower, and (b) releases, acquits, remises and forever
discharges the Agent and each Lender and its affiliates and all of their past,
present and future officers, directors, employees, agents, attorneys,
representatives, successors and assigns from any and all claims, demands,
actions and causes of action, whether at law or in equity, whether now accrued
or hereafter maturing, and whether known or unknown, which such Borrower now or
hereafter may have by reason of any manner, cause or things to and including the
date of this Amendment with respect to matters arising out of or with respect to
the Loan Agreement, the other Loan Documents, the Secured Obligations, or any
other arrangement or relationship between the Agent or any Lender and such
Borrower.

         18. The Borrowers agree to take such further action as the Agent shall
reasonably request in connection herewith to evidence the agreements herein
contained.

         19. This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which, when so
executed and delivered, shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same instrument.

         20. This Agreement shall be binding upon and inure to the benefit of
the successors and permitted assigns of the parties hereto.

         21. This Agreement shall be governed by, and construed in accordance
with, the laws of the State of Georgia, other than its laws respecting choice of
law.

                                      -12-

         IN WITNESS WHEREOF, the Borrowers, the Agent and the Lenders have
caused this Amendment to be duly executed by their authorized officers in
several counterparts, all as of the date first above written.

                              EMPLOYMENT AGREEMENT

         AGREEMENT made as of April 3, 2000 between RESOURCE BANCSHARES MORTGAGE
GROUP, INC. ("RMBG") and Harold Lewis, Jr. ("Employee").

                                   WITNESSETH:

         WHEREAS, the parties hereto desire to provide for the Employee's
employment by RBMG.

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

         1.       Employment.

         RBMG agrees to employ the Employee and the Employee agrees to enter
into the employ of RMBG on the terms and conditions hereafter set forth.

         2.       Capacity and Duties.

         The Employee shall be employed as an Executive Vice President of RMBG.
In addition, the Employee shall upon request serve as an officer and on the
Board of Directors of such subsidiaries as the Board of Directors or management
of RBMG may from time to time designate. The Employee shall perform his
responsibilities in accordance with the direction and supervision of the Board
of Directors and Chief Executive Officer of RBMG and he shall devote his full
business time, skill, energies, business judgment, knowledge and best efforts to
the advancement of the best interests of RBMG and the performance of such
executive, administrative and operational duties on behalf of RBMG and its
subsidiaries, appropriate to the offices he holds or shall hold hereunder, as
the Board of Directors or Chief Executive Officer of RBMG may assign. The
requirement that the Employee devote his full business time shall not be
construed to prevent the Employee from making investments in stocks, bonds and
other types of personal property, both tangible and intangible, and real estate
or engaging in church, charitable or other community activities which do not,
singly or in the aggregate, materially impair his ability to fulfill his
responsibilities under this Agreement.

         3.       Term.

         The term of the Employee's employment hereunder shall be for the period
commencing as of April 3, 2000 (the "Commencement Date") and ending on April 2,
2002 unless such term is terminated earlier by or pursuant to Section 5.

         4.       Compensation and Benefits.

                  (a) Salary. RBMG shall pay or cause to be paid to the
         Employee, as compensation for all of the services to be rendered by him
         hereunder during the term hereof, a salary of $225,000 per year ("Base
         Salary"), payable in accordance with the

<PAGE>   2

         regular payroll practices of RBMG for executives, less such deductions
         or amounts as are required to be deducted or withheld by applicable
         laws or regulations and less such other deductions or amounts, if any,
         as are authorized by the Employee. The Board of Directors of RBMG shall
         have the right to increase the Employee's Base Salary from time to
         time.

                  (b) Annual Bonus. The Employee shall be eligible to be
         considered for an annual bonus.

                  (c) Expenses. To the extent not otherwise paid for by RBMG or
         one of its subsidiaries, RBMG will reimburse the Employee or cause the
         Employee to be reimbursed for reasonable expenses incurred in promoting
         RBMG's and its subsidiaries' businesses, including expenses for travel
         and entertainment, such reimbursement to be made promptly upon
         presentation of appropriate receipts or other substantiation.

                  (d) Plans. The Employee shall be entitled to participate in
         any and all employee benefit plans as may be in effect for executives
         of RBMG to the extent that he is eligible for participation therein and
         coverage thereunder. Such right of participation in any such plan and
         the degree or amount thereof shall be subject, however, to generally
         applicable RBMG policies and to action by RBMG's Board of Directors or
         any administrative or other committee or to any other administrative or
         managerial determination provided in or contemplated by such plan, it
         being agreed that this Agreement is not intended to impair the right of
         any committee or other group or person concerned with the
         administration of such plan to exercise in good faith the full
         discretion reposed in him or them by such plan.

                  (e) Vacation. The Employee shall be entitled to paid vacation
         during each year of this Agreement in accordance with the policies of
         RBMG with respect thereto applicable to officers with comparable duties
         and responsibilities. Unused vacation time in any year shall not be
         carried over to subsequent years and the Employee shall not be entitled
         to pay in lieu of unused vacation time.

                  (f) Withholding. The Employee acknowledges that certain
         payments provided for herein are subject to withholding and other
         taxes.

         5.       Termination.

                  Notwithstanding Section 3, the term of the Employee's
employment hereunder shall terminate on the first to occur of the (i)
termination date provided for under Section 3 or (ii) any of the events
described in the paragraphs of this Section 5.

                  (a) Death. In the event of the Employee's death, the
         Employee's employment shall terminate automatically, effective as of
         the date of death, and RBMG shall pay to his estate the Base Salary
         that otherwise would have been paid to the Employee pursuant to Section
         4(a) up to the end of the fiscal quarter in which he died.

                                       2

<PAGE>   3

                  (b) Disability. If the Employee, due to physical or mental
         illness, shall be disabled to perform substantially all of his duties
         for a continuous period of three months (a "disability"), then either
         the Employee or RBMG may by notice terminate the Employee's employment
         under this Agreement effective as of a date 30 days after the date such
         notice is given. The Employee's Base Salary during such three-month
         period and thereafter, prior to such termination, shall be reduced by
         the amount of any disability or similar benefits to which he is
         entitled, notwithstanding anything contained elsewhere in this
         Agreement to the contrary.

                  (c) Termination for Cause. The Employee's employment may be
         terminated effective immediately by RBMG for "cause" by notice of
         termination to the Employee. "Cause" for such termination shall be
         limited to the following:

                           (i) Breach by the Employee in any material respect of
                  any of the material covenants contained in this Agreement,
                  which breach continues for 30 days following receipt of
                  written notice given by RBMG's Board of Directors or its Chief
                  Executive Officer specifying the breach and requesting that
                  the Employee correct the same;

                           (ii) Chronic and disabling use of alcohol or
                  controlled substances that materially inhibits the performance
                  of the Employee's duties under this Agreement for a period of
                  not less than three consecutive months;

                           (iii) Employee's conviction of either a felony
                  involving moral turpitude or any crime in connection with his
                  employment by RBMG which causes RBMG a substantial detriment;

                           (iv) Gross or willful neglect of the Employee's
                  duties; or

                           (v) Such conduct as results or as is likely to result
                  in substantial damage to the reputation of RBMG or any of the
                  affiliates of RBMG.

                  (d) Compensation Upon Termination. Except as provided in
         Sections 5(a) and 5(b), all compensation to the Employee shall cease
         immediately on termination of the Employee's employment hereunder.

         6.       No Raid.

                  The Employee acknowledges that he has had and will have
extensive contacts with employees and customers of, and others having business
dealings with, RBMG. For the purposes of this Section and Sections 7, 8 and 9,
the term "RBMG" shall be deemed to include subsidiaries, parents and affiliates
of RBMG. Accordingly, the Employee covenants and agrees that during the term of
his employment and during the two-year period immediately thereafter he will not
(i) solicit any of the employees of RBMG who were employed by RBMG during the
time when the Employee was employed by RBMG to leave RBMG, (ii) interfere with
the

                                       3

<PAGE>   4

relationship of RBMG with any such employees or (iii) personally target or
solicit to the detriment of RBMG any customers or others having business
dealings with RBMG in the business activities and endeavors in which the
Employee was involved. The Employee further covenants and agrees that during the
term of his employment and during the two-year period immediately thereafter he
will not make public statements in derogation of RBMG.

         7.       Blue Pencil.

                  The Employee acknowledges that the period and geographic area
of restriction imposed by Section 6 is fair and reasonable and is reasonably
required for the protection of RBMG. If any part or parts of Section 6 shall be
held to be unenforceable or invalid, then the remaining parts thereof shall
nevertheless continue to be valid and enforceable as though the invalid portion
or portions were not a part hereof. If any of the provisions of Section 6
relating to the period or geographic area of restriction shall be deemed to
exceed the maximum period of time or area which a court of competent
jurisdiction would deem enforceable, then the time and area shall, for the
purposes of Section 6, be deemed to be the maximum time period and area which a
court of competent jurisdiction would deem valid and enforceable in any state in
which such court of competent jurisdiction shall be convened.

         8.       Confidentiality.

                  The Employee acknowledges that he has had and will have access
to certain information related to the business, operations, future plans and
customers of RBMG, the disclosure or use of which could cause RBMG substantial
losses and damages. Accordingly, the Employee covenants that during the term of
his employment with RBMG and thereafter he will keep confidential all
information and documents furnished to him by or on behalf of RBMG and not use
the same to his advantage, except to the extent such information or documents
are or thereafter become lawfully obtainable from other sources or are in the
public domain through no fault on his part or as is consented to in writing by
RBMG. Upon termination of his employment, the Employee shall return to RBMG all
records, lists, files and documents which are in his possession and which relate
to RBMG.

         9.       Right to Injunctive Relief.

                  The Employee agrees and acknowledges that a violation of the
covenants contained in Sections 6 and 8 of this Agreement will cause irreparable
damage to RBMG, and that it is and will be impossible to estimate or determine
the damage that will be suffered by RBMG in the event of a breach by the
Employee of any such covenant. Therefore, the Employee further agrees that in
the event of any violation or threatened violation of such covenants, RBMG shall
be entitled as a matter of course to an injunction issued by any court of
competent jurisdiction restraining such violation or threatened violation by the
Employee, such right to an injunction to be cumulative and in addition to
whatever other remedies RBMG may have.

         10.      Representation by the Employee.

                                       4

<PAGE>   5

                  The Employee hereby represents and warrants to RBMG that the
execution of this Agreement and the performance of his duties and obligations
hereunder will not breach or be in conflict with any other agreement to which he
is a party or by which he is bound and that he is not now subject to any
covenant against competition or similar covenant that would affect the
performance of his duties hereunder.

         11.      No Assignment.

                  This Agreement is personal and shall in no way be subject to
assignment, except by RBMG incident to the sale of all or substantially all of
its business (whether by asset sale, stock sale or merger). Any attempt by one
party to assign this Agreement in any other circumstances without the prior
written consent of the other party shall be null and void.

         12.      Enforceability.

                  If any portion or provision of this Agreement shall to any
extent be declared illegal or unenforceable by a duly authorized court of
competent jurisdiction, then the remainder of this Agreement, or the application
of such portion or provision in circumstances other than those as to which it is
so declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

         13.      Notices.

                  All notices and other communications required or permitted to
be given hereunder shall be given by delivering the same in hand or by mailing
the same by certified or registered mail, return receipt requested, postage
prepaid, as follows:

2000 between the Company and the Employee, employee benefit plans, policies and
practices applicable to RBMG's executive officers generally) between RBMG, on
the one hand, and the Employee, on the other hand, in relation to the subject of
the Employee's employment by RBMG; and there are no promises, representations,
conditions, provisions or terms related thereto other than those set forth
herein. This Agreement supersedes all previous understandings, agreements and
representations, written or oral, between RBMG and the Employee regarding the
Employee's employment by RBMG.

         15.      Governing Law.

                  This contract shall be construed under and be governed in all

         16.      Waiver;  Amendment.

                  No waiver in any instance by either party of any provision of
this Agreement shall be deemed a waiver by such party of such provision in any
other instance or a waiver of any other provision hereunder in any instance.
This Agreement cannot be amended, supplemented or otherwise modified except in a
writing signed by RBMG and the Employee.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day first above written.
