          with respect to the termination of each Warrant, for a payment equal
          to (1) the Common Share Equivalent Consideration, less the exercise
          price set forth in such Warrant, multiplied by (2) the number of
          Common Shares issuable upon exercise of such Warrant in full.

                    (I) Purchaser shall pay the balance of the Purchase Price,

respective calculation of each item in dispute (the "DISPUTED ITEMS"). The
Purchaser and the Seller Representative shall negotiate in good faith to resolve
any Disputed Items. If Purchaser and the Seller Representative are unable to
agree upon the same dollar value of any Disputed Item (the unresolved items
being the "REMAINING DISPUTED ITEMS") within fifteen (15) days after the Seller
Representative's delivery of notice of disagreement regarding the Closing
Statement, such disagreement shall be resolved in accordance with the procedure
set forth in Section 2.6(e), which shall be the sole and exclusive remedy for
resolving disputes relative to the determination of the Net Working Capital as
of the Closing Date.

          (e) In the event that the Seller Representative and the Purchaser are
not able to agree on the Net Working Capital as of the Closing Date within
thirty (30) days after the Seller Representative's delivery of notice of
disagreement, the Seller Representative and the Purchaser shall each have the
right to require that the Remaining Disputed Items be submitted to Deloitte &
Touche LLP, or if Deloitte & Touche LLP is not available for any reason or does
not maintain its independent status, such other independent certified public
accounting firm as the Seller Representative and the Purchaser may then mutually
agree upon in writing (the "ACCOUNTING FIRM") for computation or verification in
accordance with the provisions of this Agreement. Purchaser and the Seller
Representative shall each present in writing to the Accounting Firm (i) its
proposed resolution of each of the Remaining Disputed Items (on an item by item
basis) and (ii) any materials it wishes to present to justify the resolution it
so presents. The Accounting Firm shall review each of the proposed resolutions
submitted by Purchaser and the Seller Representative concerning each of the
Remaining Disputed Items together with the supporting materials submitted in
favor thereof. Purchaser and the Seller Representative shall instruct the
Accounting Firm to adopt the resolution of each Remaining Disputed Item (on an
item by item basis) proposed by either Party in their respective supporting
materials (and the Accounting Firm shall have no power whatsoever to reach any
other result) and the Accounting Firm shall adopt the resolution of each item
that in its judgment is the most fair, equitable and in conformity with this
Agreement. The Accounting Firm may adopt Purchaser's resolution of some items
and the Seller Representative's resolution of other items. Purchaser and the
Seller Representative shall instruct the Accounting Firm to reach its final
decision within thirty (30) days after the Parties' presentation of the
Remaining Disputed Items to the Accounting Firm. The submission of the Remaining
Disputed Items to the Accounting Firm shall be the exclusive remedy for
resolving disputes relative to the determination of Net Working Capital. The
Accounting Firm's determination shall be binding upon the Seller Representative,
the Securityholders and the Purchaser. If at any time the Parties resolve their
dispute, then, notwithstanding the preceding provisions of this Section 2.6(e),
the arbitration procedures promptly shall be discontinued and the calculation of
the affected item shall be revised, if necessary, to reflect such resolution and
thereupon shall be final and binding on the Parties. The Accounting Firm's fees
and expenses shall be borne equally by the Securityholders and the Purchaser.
The portion of such fees and expenses borne by the Securityholders shall be
satisfied from the Escrow Funds. Purchaser and the Seller Representative shall
jointly instruct the Escrow Agent to disburse to the Accounting Firm an amount
equal to one-half of the fees and expenses of such Accounting Firm. Each
Securityholder shall be deemed to bear its pro rata share of such


                                       9

fees and expenses based on its percentage interest of the Escrow Funds, which
percentage interest is set forth on Schedule 1 to the Escrow Agreement.

          (f) Promptly following the first to occur of (i) the last day of the
period during which the Seller Representative may dispute the Closing Statement
(unless the Seller Representative has disputed same), (ii) the resolution of any
disputed Closing Statement items pursuant to agreement of the Seller
Representative and Purchaser or (iii) the end of the dispute resolution process
described in Section 2.6(e), the Seller Representative or Purchaser or, if any
of the disputed Closing Statement items are resolved by the Accounting Firm, the
Accounting Firm, shall restate the Closing Statement taking into account any
changes that have been agreed to by the Seller Representative and Purchaser or
that have been finally determined by the Accounting Firm. The Closing Statement,
as so restated or, in the case of clause (i), the unadjusted Closing Statement,
is referred to as the "FINAL WORKING CAPITAL STATEMENT." The difference between
(A) the sum of the asset line items in the Final Working Capital Statement and
(B) the sum of the liability line items in the Final Working Capital Statement
is referred to as the "FINAL WORKING CAPITAL AMOUNT." If the Final Working
Capital Amount differs from the Estimated Net Working Capital, the Seller
Representative and Purchaser shall promptly (within two Business Days after the
Final Working Capital Amount is determined) make a true-up payment so that,
following such payment, the parties are in the same position they would have
been in had the Final Working Capital Amount been known at the Closing and used
in lieu of the Estimated Net Working Capital in determining the amount of the
payment under Section 2.4(b). Any payment received by the Seller Representative
pursuant to Section 2.4(b)(i)(F) shall be held by the Seller Representative
until the Final Working Capital Amount is determined pursuant to this Section
2.6. Any payment required of Purchaser shall be paid in cash by Purchaser to the
Seller Representative, and any payment required of the Securityholders shall be
satisfied first from the amount, if any, paid to the Seller Representative
pursuant to Section 2.4(b)(i)(F), and if any amounts remain owing to Purchaser
following payment of such funds, from the Escrow Funds. The Seller
Representative shall promptly disburse all funds retained as a result of any
payment pursuant to Section 2.4(b)(i)(F) or received pursuant to this Section
2.6(f) in respect of the Final Working Capital Amount to the Securityholders in
proportion to each such Securityholder's percentage interest in the Escrow
Funds, which percentage interest is set forth for each Securityholder on
Schedule 1 to the Escrow Agreement. In the event any payment is required of the
Securityholders from the Escrow Funds, Purchaser and the Seller Representative
shall jointly instruct the Escrow Agent to disburse to Purchaser the amount
owing to Purchaser. Each Securityholder shall be deemed to bear its pro rata
share of the expenses described in the preceding sentence based on its
percentage interest of the Escrow Funds.

                                   ARTICLE III
                                     ESCROW

     3.1 ESCROW DEPOSIT. Subject to the terms and conditions of this Agreement,

          (b) In the event that the Securityholders become obligated finally to
Purchaser or any of the other Purchaser Indemnitees under this Agreement (as
determined by final, non-appealable judgment), at Purchaser's request, the
Seller Representative shall promptly execute a joint instruction letter with
Purchaser directing the Escrow Agent to disburse Escrow Funds to satisfy such
obligations.

          (c) In the event the Company (i) becomes obligated to pay and actually
pays any portion of the El Paso Earn-Out or (ii) the Company fails to satisfy
the conditions precedent for the El Paso Earn-Out, at Purchaser's request and,
in the case of clause (i), upon receipt of evidence reasonably satisfactory to
the Seller Representative of such payment, the Seller Representative shall
promptly execute a joint instruction with Purchaser directing the Escrow Agent
to disburse Escrow Funds to Purchaser in an amount equal to the lesser of
$2,000,000 and the remaining Escrow Funds.

          (d) In addition to any disbursements of the Escrow Funds pursuant to
above provisions of this Section 3.2, Purchaser and the Seller Representative
for the benefit of the Securityholders shall issue joint instructions to the
Escrow Agent to effect the following disbursements:

                    (i) On the 270th day following the Closing Date, Purchaser
          and the Seller Representative shall jointly instruct the Escrow Agent
          to disburse to the Seller Representative for the benefit of the
          Securityholders an amount equal to 50% of Escrow Funds less (A) the
          amount, if any, of Escrow Funds which the Escrow Agent has (1)
          disbursed pursuant to the Escrow Agreement prior to such date or (2)
          been instructed to disburse in accordance with the Escrow Agreement
          but not actually disbursed as of such date and (B) a reasonable
          reserve amount (to be determined by Purchaser and the Seller
          Representative in good faith, or, to the extent Purchaser and Seller
          Representative are unable to agree, pursuant to the dispute resolution
          provisions contained in Section 10.7 of this Agreement) in respect of
          (x) any claims submitted by any Purchaser Indemnitee in accordance
          with Article X that remain pending at such time and (y) the El Paso
          Earn-Out (but only if such payment is then reasonably likely to become
          payable by the Company).

                    (ii) On the first business day on or after the 540th day
          following the Closing Date, Purchaser and the Seller Representative
          shall jointly instruct the Escrow Agent to disburse to the Seller
          Representative for the benefit of the Securityholders an amount equal
          to the remaining Escrow Funds as of such date, if any, less (A) the
          amount, if any, of Escrow Funds which the Escrow Agent has


                                       11

<PAGE>

          been instructed to disburse in accordance with the Escrow Agreement
          but not actually disbursed as of such date and (B) a reasonable
          reserve amount (to be determined by Purchaser and the Seller
          Representative in good faith, or, to the extent Purchaser and the
          Seller Representative are unable to agree, pursuant to the dispute
          resolution provisions contained in Section 10.7 of this Agreement) in
          respect of any claims submitted by any Purchaser Indemnitee in
          accordance with Article X that remain pending at such time.

          (e) Following resolution from time to time of any claim for which a
reserve of a portion of the Escrow Funds was established, Purchaser and the
Seller Representative will jointly instruct the Escrow Agent to release such
reserve amount from the Escrow Funds to the Seller Representative for the
benefit of the Securityholders, to a Purchaser Indemnitee or to both, as
appropriate for the resolution of such claim.

          (f) The Seller Representative shall promptly disburse all funds
received pursuant to this Section 3.2 to the Securityholders in proportion to
each such Securityholder's percentage interest in the Escrow Funds, which
percentage interest is set forth for each Securityholder on Schedule 1 of the
Escrow Agreement.

any Subsidiary has (i) received any notice that the Company or any Subsidiary is
in default under, or not in material compliance with any Real Property Lease, or
that there may be any material changes in property tax or land use law affecting
any Real Property Lease and that would materially impair the use of such
property by the Company or any Subsidiary, as currently used, or (ii) delivered
any notice to another party alleging any default under, or failure to comply
with any material provision of, any Real Property Lease. To the Knowledge of the
Company, no event has occurred that, with notice, the passage of time or both,
would constitute a material default by the Company or any Subsidiary under, or
failure of the Company or any Subsidiary to comply materially with any provision
of, any Real Property Lease, or otherwise give any party a right of termination
or modification thereof.

          (c) The property covered by the Real Property Leases constitutes all
of the real property (other than the Non-FBO Assets) currently used in the
conduct of the Business, other than the Easterwood Airport Fixed Base Operation
Lease Agreement, effective October 1, 2003 between The Texas A&M University and
Trajen, Inc., and the Company's leasehold interests in such leased real property
are free and clear of Liens, except for Permitted Liens.

          (d) (i) Neither the Company nor any Subsidiary has received written
notice of any threatened condemnation proceedings, lawsuits or administrative
actions relating to any of the real property used in the Business, and there are
no pending or, to the Knowledge of the Company, threatened, condemnation
proceedings, lawsuits or administrative actions relating to any of the real
property used in the Business that, in either case, would materially and
adversely affect the Business.

               (ii) All facilities, buildings, improvements and other structures
          used in the Business are located on the real property leased by the
          Company and the Subsidiaries.

               (iii) To the Knowledge of the Company, none of the real property
          leased by the Company or the Subsidiaries or any of the structures
          thereon used in the Business are dependent upon or benefit from any
          "non-conforming use" or similar zoning classification.

               (iv) Other than in the ordinary course of business (e.g., hangar
          leases), there are no parties other than the Company or any Subsidiary
          in possession of any of the real property leased by the Company and
          the Subsidiaries or any portion thereof, and, other than in the
          ordinary course of business (e.g., hangar leases), there are no
          Contracts granting to any party or parties the right of use or
          occupancy of any of such leased real property or any portion thereof.

               (v) To the Knowledge of the Company, legal descriptions for the
          real property contained in the Real Property Leases adequately
          describe the leased real property subject thereto. To the Knowledge of
          the Company, all structures on the real property leased by the Company
          and the Subsidiaries are located within the boundary lines of the
          leased real property and no structures, facilities or other
          improvements on any parcel adjacent to any of the leased real property
          encroach in any material respect onto any of the real property leased
          by the Company or the Subsidiaries. To the Knowledge of the Company,
          all structural, mechanical and other physical systems related to the
          real property leased by the Company or any Subsidiary are in a
          condition sufficient, in all material respects, to operate the
          Business in accordance with past practices.

               (vi) Except as set forth on Schedule 5.15(d)(vi), the Company is
          not obligated to any third party to make any capital expenditures that
          exceed $100,000 individually, or $500,000 in the aggregate, for real
          property fixtures or improvements thereon.


                                       28

          (e) Schedule 5.15(e) contains a list, as of the Execution Date, of all
hangar space, office space and real property subleased by the Company or any
Subsidiary to any other party, other than leases that may be terminated on less
upon less than 60 days' notice or that require rental payments of less than
$10,000 per month. All subleases identified on Schedule 5.15(e) (the "LANDLORD
PROPERTY LEASES") are in full force and effect, have not been modified, amended
or, to the Knowledge of the Company, assigned. Each Landlord Property Lease is
the valid and binding obligation of the Company or any Subsidiary party thereto,
except as the enforceability thereof may be limited by bankruptcy, insolvency,
reorganization, moratorium or other Legal Requirements relating to or affecting
creditors' rights generally or by equitable principles. The Company has
delivered to Purchaser complete and accurate copies of each Landlord Property
Lease.

     5.16 PERSONAL PROPERTY. Except as described in Schedule 5.16, the Company
or a Subsidiary has good title to (or a valid leasehold interest in) all of the
tangible personal property (other than the Non-FBO Assets) currently used in the
conduct of the Business, and such title or leasehold interests are free and
clear of Liens, except for Permitted Liens. The Company has valid titles and
registrations for each motor vehicle owned by the Company and the Subsidiaries,
all of which owned as of the Execution Date are listed on Schedule 5.16 and
copies of which have been delivered to Purchaser.

     5.17 INTELLECTUAL PROPERTY.

          (a) Schedule 5.17(a) identifies all of the following intellectual
property (the "INTELLECTUAL PROPERTY") which is, as of the date of this
Agreement, used by the Company or any Subsidiary: (i) all registered trademarks
and service marks (collectively, "TRADEMARKS"), (ii) all patents and pending
applications to patent any technology or design which are material to the
Business, (iii) all registrations of and applications to register copyrights
which are material to the Business, and (iv) all material licenses to which the
Company is the licensee relating to technology, know-how, or software used by
the Business, whether proprietary to the Company or licensed or otherwise
authorized to use by others.

          (b) The Company and the Subsidiaries have good title (free of Liens
other than Permitted Liens) to, or are duly licensed to use (or permitted by
similar agreement to use) each item of Intellectual Property. The use by the
Company or any Subsidiary of the Intellectual Property does not infringe any
rights of any third party and, to the Knowledge of the Company, no activity of
any third party infringes upon the rights of the Company or any Subsidiary with
respect to any of the Intellectual Property. Neither the Company nor any
Subsidiary has received notice of any claims asserted by any Person with respect
to challenging the ownership, validity, enforceability or use of the
Intellectual Property, nor to Knowledge of the Company, are there any valid
grounds for any such bona fide claims. To the extent the Company or any
Subsidiary uses any Intellectual Property owned by a third party, the Company or
any Subsidiary has a license with such third party for the use of such
Intellectual Property and is not in default under any such license.

     5.18 INSURANCE. Schedule 5.18 lists all insurance policies insuring the
Business and the Company's or any Subsidiary's assets (the "INSURANCE POLICIES")
maintained by or on behalf


                                       29

<PAGE>

of the Company and the Subsidiaries and includes a description of any material
self-insurance arrangements currently in effect with respect to the Company and
the Subsidiaries. Each such Insurance Policy is in full force and effect. All
insurance premiums currently due with respect to such Insurance Policies have
been paid. Neither the Company nor any Subsidiary has received notice of
cancellation or non-renewal of any such Insurance Policy. Except as set forth on
Schedule 5.18, there are no claims related to or arising out of the operation of
the Business pending under any Insurance Policies.

     5.19 BANK ACCOUNTS; POWERS OF ATTORNEY. Schedule 5.19 lists each bank,
trust company, savings institution, brokerage firm, mutual fund or other
financial institution with which the Company or any Subsidiary has an account or
safe deposit or lock box and the names and identification of all persons
authorized to draw on it or to have access to it.

     5.20 RELATED PARTY TRANSACTIONS. Except as set forth in Schedule 5.20, no
stockholder, officer or director of the Company or any Subsidiary or immediate
family member thereof (a) is presently a party to any material agreement with
the Company or any Subsidiary or (b) owns any interest in any assets of the
Company or any Subsidiary. Any and all contracts between the Company on the one
hand and any Affiliate of the Company on the other hand (other than the
Company's Charter Documents) are listed on Schedule 5.20, and the Company has
delivered to Purchaser complete and correct copies of each such contract.

     5.21 BROKER. The Company is not liable for any investment banking fee,
finder's fee, brokerage payment or other like payment in connection with the
origination, negotiation or consummation of the transactions contemplated herein
that will be the obligation of the Company, any Subsidiary or Purchaser. The
Company is not a party to any agreement, and has not committed any act which
might give rise to any valid claim against the Company, any Subsidiary or
Purchaser for any such fee, commission or similar payment.

Purchaser. This Agreement constitutes, and each of the other Transaction
Documents to which Purchaser will be a party as of the Closing will constitute,
the valid and binding obligation of Purchaser, enforceable against Purchaser in
accordance with its terms, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or other Legal Requirements
relating to or affecting creditors' rights generally or by equitable principles.
Except for the approvals required under the HSR Act, Purchaser has, in
accordance with all Legal Requirements, the Charter Documents of Purchaser, and

all actions necessary for the authorization, execution, delivery and performance
by Purchaser, of this Agreement and the other Transaction Documents.

     6.3 NO VIOLATIONS. The execution and delivery of this Agreement and the

under any of the provisions of Purchaser's Charter Documents; or

          (b) except for approval under the HSR Act or as set forth on Schedule
6.3, violate, conflict with, result in a breach or constitute a default under

knowledge of Purchaser, threatened against Purchaser that (a) challenge the
validity or enforceability of any of Purchaser's obligations under this
Agreement or the other Transaction Documents to which Purchaser is or will be a
party or (b) seek to prevent, delay or otherwise would reasonably be expected to
adversely affect the consummation by Purchaser of the transactions contemplated
herein or therein.

obligations under this Agreement, and Purchaser has currently available all
funds, resources and capabilities necessary to pay the Purchase Price and any
other amounts contemplated by this Agreement and to perform its obligations
under this Agreement. Without limiting the foregoing, Purchaser's ability to
consummate the transactions contemplated hereby is not contingent on Purchaser's
ability to complete any public offering or private placement of equity or debt
securities, for which Purchaser does not already have commitments, on or prior
to the Closing Date.

<PAGE>

other clauses of this Section 7.1.; or

          (q) take or agree to take any of the actions described above.

     7.2 ESTOPPELS; CONSENTS; HSR ACT.

          (a) The Company and the Purchaser shall use commercially reasonable
efforts to obtain, prior to Closing, any third party consents required in
connection with the transactions contemplated by this Agreement. The Company and
Purchaser shall use commercially reasonable efforts to obtain, as promptly as
practicable, estoppel letters (each an "AIRPORT ESTOPPEL") substantially in the
form of Exhibit G, with such modifications as are reasonably agreed to by the
Company and Purchaser to address particular circumstances of a particular
airport authority, from the airport authorities listed on Schedule 7.2(a).

          (b) In furtherance of the foregoing, the Parties covenant and agree to
prepare and submit the Airport Estoppels to the airport authorities listed on
Schedule 7.2(a) within five days following the Execution Date; provided, that,
in no event shall any Airport Estoppel be submitted before MIC has, in
accordance with applicable Legal Requirements, issued a press release announcing
the transactions contemplated hereby, which shall be released within four
Business Days following the Execution Date. Purchaser will be available on
36-hour notice from the Company to meet with representatives from the airport
authorities. All contact with the airport authorities regarding the Airport
Estoppels will be coordinated through the Company. Purchaser will furnish the
airport authorities with such evidence and assurances as the airport authorities
reasonably request regarding the Purchaser's structure, organization,
creditworthiness, insurance coverage and operating experience.

          (c) In the event that any airport authority to which an Airport
Estoppel is delivered pursuant to Section 7.2(b) does not respond to the
estoppel request within 60 days following the Execution Date, each such airport
authority that is designated as a "Required Authority" on Schedule 7.2(a) (each,
unless and until removed from Section 7.2(a) in accordance with this Section
7.2(c), a "REQUIRED AUTHORITY") shall be automatically removed as a Required
Authority from Schedule 7.2(a). In the event that an airport authority has not
responded to an estoppel request within 35 days following the Execution Date,
the Company shall use commercially reasonable efforts to provide Purchaser and
its representatives with access to such airport authority to permit Purchaser an
opportunity to obtain a response to the estoppel request within the prescribed
60-day period. In the event that any airport authority to which an Airport
Estoppel is delivered pursuant to Section 7.2(b) advises the Company or the
Purchaser within 60 days following the Execution Date that it does not, as a
matter of policy or otherwise, respond to requests for estoppel or furnish
estoppel letters, each such airport authority that is a Required Authority shall
be automatically removed as a Required Authority from Schedule 7.2(a). The
removal of any Required Authority from Schedule 7.2(a) pursuant to this Section
7.2(c) is referred to as an "AUTOMATIC ELIMINATION."

          (d) In the event that an Airport Estoppel is not received from any
Required Authority within 90 days following the Execution Date and such airport
authority has not been


                                       34

<PAGE>

subject to an Automatic Elimination pursuant to Section 7.2(c), Purchaser may on
or before the fifth day following such 90th day elect to remove such airport
authority from the list of Required Authorities on Schedule 7.2(a). In the event
that Purchaser elects not to remove any such airport authority from the list of
Required Authorities on Schedule 7.2(a), the Seller Representative may on or
before the tenth day following such 90th day after the Execution Date terminate
this Agreement or extend the estoppel period with respect to such airport
authority for an additional 30-day period. In the event such Airport Estoppel
has not been obtained during such additional 30-day period, the Seller
Representative may elect to extend such estoppel period for an additional 30
days or terminate this Agreement. In the event such Airport Estoppel has not
been obtained during such additional 30-day period, the Seller Representative
may elect to extend such estoppel period for up to an additional 30 days or
terminate this Agreement. If any Airport Estoppel has not been obtained from any
Required Authority (excluding any Required Authority subject to an Automatic
Elimination) within 180 days following the Execution Date, Purchaser or the
Seller Representative may terminate this Agreement.

          (e) In the event that any Required Authority responds to the estoppel
request within 60 days following the Execution Date and indicates that consent
is required of such Required Authority (notwithstanding the absence of any
consent requirement in the FBO Lease between such airport authority and the
Company) in connection with the transactions contemplated by this Agreement, the
Company and Purchaser shall use commercially reasonable efforts to obtain, as
promptly as practicable, consent from such Required Authority. These efforts
would include submitting a consent request in the form requested by the Required
Authority or, if the Required Authority does not request a particular form, in a
form reasonably acceptable to Purchaser and the Seller Representative. If a
Required Authority conditions its consent on making modifications to the
applicable FBO Lease, Purchaser will agree to such modifications as long as the
modifications do not materially impact the Company's Business or consolidated
financial results, including as a result of material obligations to finance
capital expenditures imposed by a Required Authority. If any consent requested
of a Required Authority is not obtained from such Required Authority within 90
days following the Execution Date, Purchaser may on or before the fifth day
following such 90th day elect to remove such airport authority from the list of
Required Authorities on Schedule 7.2(a). In the event that Purchaser elects not
to remove any such airport authority from the list of Required Authorities on
Schedule 7.2(a), the Seller Representative may on or before the tenth day
following such 90th day after the Execution Date terminate this Agreement or
extend the consent period with respect to such airport authority for an
additional 30-day period. In the event such consent has not been obtained during
such additional 30-day period, the Seller Representative may elect to extend
such consent period for an additional 30 days or terminate this Agreement. In
the event such consent has not been obtained during such additional 30-day
period, the Seller Representative may elect to extend such consent period for up
to an additional 30 days or terminate this Agreement. If a requested consent has
not been obtained from any Required Authority within 180 days following the
Execution Date, Purchaser or the Seller Representative may terminate this
Agreement.

          (f) No later than 10 Business Days following the Execution Date,
Purchaser and the Company shall make such filings as may be required by the HSR
Act with respect to the


                                       35

<PAGE>

transactions contemplated by this Agreement and the other Transaction Documents.
Thereafter, Purchaser and the Company shall file as promptly as practicable all
reports or other documents required or requested by the U.S. Federal Trade
Commission or the U.S. Department of Justice pursuant to the HSR Act or
otherwise including requests for additional information concerning such
transactions, so that the waiting period specified in the HSR Act will expire as
soon as reasonably possible after the Execution Date. Without limiting the
foregoing, Purchaser and the Company shall use commercially reasonable efforts
to cooperate and oppose any preliminary injunction sought by any Governmental
Entity under the HSR Act preventing the consummation of the transactions
contemplated by this Agreement and the other Transaction Documents; provided,
neither the Company nor Purchaser will be required to divest any of its assets
in connection with these efforts. Purchaser shall pay the statutory filing fee
associated with filings under the HSR Act.

          (g) Purchaser and the Company shall cause their respective counsel to
furnish the other party such necessary information and reasonable assistance as
the other may reasonably request in connection with its preparation of necessary
filings or submissions under the provisions of the HSR Act. Purchaser and the
Company shall cause their respective counsel to supply to the other party copies
of all correspondence, filings or written communications by such Party or its
Affiliates with any Governmental Entity or staff members thereof, with respect
to the transactions contemplated by this Agreement and the other Transaction
Documents, except for documents filed pursuant to Item 4(c) of the HSR
Notification and Report Form or communications regarding the same, documents or
information submitted in response to any request for additional information or
documents pursuant to the HSR Act which reveal any Party's negotiating
objectives, strategies or purchase price expectations.

     7.3 ACCESS AND ASSISTANCE.

          (a) Upon receipt of reasonable advance notice, the Company will afford
to Purchaser and its authorized representatives reasonable access from the
Execution Date through the Closing Date, during normal business hours, solely in
furtherance of Purchaser's investigation of the Company, the Subsidiaries and
the transactions contemplated hereby, to the Company's (including the Company's
and each Subsidiary's) offices, properties, and books and records, and to the
Company's (including the Company's and each Subsidiary's) officers and
management team, and will furnish to Purchaser such additional information
regarding the business of the Company and the Subsidiaries as Purchaser may
reasonably request, to the extent that such access and disclosure would not
violate the terms of any agreement to which the Company or any Subsidiary is
bound, any applicable Legal Requirement, result in any loss of attorney-client
or other privilege or significantly disrupt the Company's operations. All
information obtained pursuant to this Section shall be "Confidential
Information" as defined in the Confidentiality Agreement and shall be subject to
the terms thereof. Notwithstanding anything to the contrary contained herein,
prior to Closing, without prior written consent of the Company, which may be
withheld for any reason, Purchaser shall not contact any suppliers to, or
customers of, the Company or any Subsidiary with respect to the transactions
contemplated hereby.

          (b) The Company will furnish to Purchaser, promptly after the
completion thereof by KPMG (but in any event no later than May 31, 2006), the
audited balance sheet of the Company and its consolidated subsidiaries as of
December 31, 2005, and the related audited statements of income, stockholders'
equity and cash flows of the Company for the year then ended, prepared in
accordance with GAAP applied on a consistent basis in a form that complies with
Regulation S-X under the Securities Act (the "AUDITED 2005 FINANCIAL
STATEMENTS"). On or before the 45th day following the end of each fiscal quarter
ending on or before the Closing (to the extent such 45th day falls on a date
prior to the Closing Date), the Company will furnish to Purchaser an unaudited
quarterly balance sheet of the Company and its consolidated subsidiaries as of
the end of such fiscal quarter, and the related unaudited statements of income,
stockholders' equity and cash flows of the Company for the quarter then ended,
in a form that complies with Regulation S-X under the Securities Act and such
other information reasonably requested by the managing underwriter in connection
with any registered offering. On or before the 30th day following the end of
each month ending on or before the Closing (to the extent such 30th day falls on
a date prior to the Closing Date), the Company will furnish to Purchaser an
unaudited monthly balance sheet of the Company and its consolidated subsidiaries
as of the end of such month, and the related unaudited statements of income,
stockholders' equity and cash flows of the Company for the month then ended, in
a form consistent with monthly financial statements historically prepared by the
Company. The Company shall use commercially reasonable efforts, at Purchaser's
sole cost and expense, to obtain comfort letters from the Company's accountants
regarding information about the Company and the Subsidiaries as reasonably
requested by the managing underwriter in connection with any registered offering
or otherwise, and the consent of such accountants to the inclusion of that
information in appropriate filings with the Securities and Exchange Commission.
The Parties acknowledge and agree that a material inducement to the Company and
Sellers entering into this Agreement is the absence of a condition to closing
predicated upon Purchaser's ability to obtain financing to consummate the
transactions contemplated by this Agreement. Accordingly, the closing of the
transactions contemplated by this Agreement shall not be conditioned upon the
receipt of any such financing, and Purchaser hereby agrees that absent willful
or intentional breach of this Section 7.3(b) by the Company the condition set
forth in Section 8.1(a) shall be deemed satisfied.

          (c) From and after the Execution Date, the Seller Representative shall
cooperate fully (and prior to the Closing shall cause the Company and the
Subsidiaries to cooperate fully), as and to the extent reasonably requested by
the Purchaser, in connection with the filing of Tax Returns. From and after the
Closing Date, the Seller Representative shall cooperate fully, as and to the
extent reasonably requested by the Purchaser, in connection with the filing of
Tax Returns and any audit, litigation or other proceeding with respect to Taxes.
In each case, such cooperation shall include the retention and (upon the
Purchaser's request) the provision of records and information which are
reasonably relevant to any such Tax Return filing, audit, litigation or other
proceeding and making employees available on a mutually convenient basis to
provide additional information and explanation of any material provided
hereunder. Purchaser shall reimburse the Seller Representative for reasonable
out-of-pocket expenses incurred by the Seller Representative in connection with
its compliance with this Section 7.3(c).

shall cause the employment of (i) Daniel Bucaro and the DOD & IT Employees to be

vacation and severance programs, Purchaser shall cause the employee benefit
plans and programs maintained by Purchaser and its Affiliates to credit the
individuals employed by the Company and the Subsidiaries on the Closing Date,
after taking into account the transfers required by Section 7.4(b) ("CONTINUING
EMPLOYEES") with their service with the Company and its Affiliates (and any
predecessors) to the extent such service was recognized under a similar plan of
the Company or a Subsidiary as of the Closing.

          (d) Purchaser shall either cause the Company to continue its employee
benefit plans in effect on the Closing or provide the Continuing Employees with
employee benefit plans on the same basis as such plans are provided to
comparable employees of Purchaser and its Affiliates.

          (e) Following the Closing, Purchaser shall ensure that each general
manager at each of the Company's and the Subsidiaries' FBO locations is given
the opportunity to continue employment for the 12-month period beginning on the
Closing Date, and that such employment shall be on substantially the same salary
and benefit terms as are in effect on the Closing Date or better; provided, the
foregoing shall not prevent Purchaser from terminating any person's employment
based on Purchaser's customary performance standards.

          (f) The Company and the Subsidiaries shall cause Trajen Flight
Support, L.P. to cease to be a participating employer in the 401(k) Plan as of
the Closing Date and shall cause Trajen, Inc. (or its successor) and Trajen

the spinoff from its cafeteria plan of the accounts of the DOD & IT Employees
under such plans to a new cafeteria plan established by Trajen, Inc. (or its
successor) or Trajen Systems LP Following the Closing the Company and Purchaser
shall take all reasonable actions with respect to the cafeteria plan to help
effectuate such spinoff.

          (h) To the extent any of the employees transferred in connection with
the Non-FBO Asset Distribution are entitled to continuation coverage under a
Company group health plan following the Closing pursuant to Section 4980B of the
Code, the entities included in the Non-FBO Assets shall be responsible for
providing notices and any required coverage.


                                       38

<PAGE>

          (i) The Company shall cause the accounts of all Continuing Employees
in the 401(k) Plan to become 100% vested as of the Closing Date.

          (j) The Company will use commercially reasonable efforts to obtain
stockholder approval in a manner that satisfies the requirements of Section
280G(b)(5) of the Code with respect to the matters listed on Schedule 5.9(g).

          (k) The Company and the Subsidiaries shall cause all Company Benefit
Plans, other than the 401(k) Plan, to be amended to the extent required to
ensure that employees of post-Closing affiliates of the Purchaser, other than
the entities acquired pursuant to this Agreement, shall not be eligible to
participate in any Company Benefit Plan.

     7.5 DISTRIBUTION OF NON-FBO ASSETS. On or prior to the Closing, the Company
and the Subsidiaries shall distribute or dispose of the equity interests of the
entities listed in the definition of "Non-FBO Assets" on the terms described in
Schedule 7.5 (such transactions referred to herein as the "NON-FBO ASSET
DISTRIBUTION"). In the event that applicable Tax laws are revised or new Tax
laws are adopted prior to Closing that adversely affect the tax treatment of the
Non-FBO Asset Distribution, Purchaser and the Seller Representative will
negotiate in good faith to revise Schedule 7.5 that permits for a tax efficient
distribution of the Non-FBO Assets in a manner reasonably acceptable to
Purchaser and the Seller Representative. In connection with the Non-FBO Asset
Distribution, the entity or entities subject to such distribution will retain
all liabilities and obligations associated with the ownership, operation and
distribution of the Non-FBO Assets and will indemnify the Purchaser Indemnitees
with respect to such liabilities and obligations as more specifically described
on Schedule 7.5. The entity or entities subject to such Non-FBO Asset
Distribution shall not make any distribution or otherwise take any action the
purpose of which is to evade or circumvent the foregoing indemnity prior to the
eighteen-month anniversary of the Closing Date. In the event that such entities
do not for any reason satisfy such indemnification obligations, Purchaser and
the Seller Representative will execute a joint instruction letter directing the
Escrow Agent to disburse Escrow Funds (to the extent such funds remain
available) to Purchaser to satisfy such required indemnification obligations.

     7.6 REMEDIATION. With respect to the two small spills of jet fuel at the
Casper, Wyoming FBO described in the most recent Phase I related to such FBO
included in Schedule 5.8 and Aspen, Colorado FBO described in the most recent
Phase I related to such FBO included in Schedule 5.8, the Company shall use
commercially reasonable efforts to (a) obtain a determination from the
appropriate Governmental Entity that no remedial action is required or (b)
remediate any contamination resulting from the spills to the extent required by
the appropriate Governmental Entity, in each case prior to the Closing Date.

     7.7 PUBLIC ANNOUNCEMENTS. The Parties agree that, except to the extent
necessary to comply with the requirements of (a) applicable Legal Requirements,
(b) any listing agreements with securities exchanges or (c) the rules,
regulations or orders of any other Governmental Entity, no press release or
similar public announcement or communication shall ever, whether prior to or
subsequent to the Closing, be made or caused to be made concerning the specific
terms of this Agreement unless approved in advance by Purchaser and Seller
Representative;


                                       39

<PAGE>

provided, with respect to any press release or similar public announcement or
communication permitted hereby, the Parties agree that each shall give
reasonable notice and consult with each other prior to issuing any such press
release or otherwise making a public announcement or communication.
Notwithstanding the foregoing, the Sellers and the Company hereby consent to
Purchaser and its Affiliates disclosing information regarding the Company,
Subsidiaries and Business, to the extent contemplated by Section 7.3(b) and
provided such disclosure is made in accordance with and pursuant to Legal
Requirements (including applicable federal securities laws and stock exchange
listing rules).

     7.8 COMMERCIALLY REASONABLE EFFORTS. Subject to the terms and conditions of
this Agreement, each of Purchaser and the Company shall use commercially
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary or desirable to consummate the
transactions contemplated by this Agreement and the other Transaction Documents
and to ensure the satisfaction of its conditions to Closing set forth herein.

     7.9 RESTRICTIVE COVENANTS.

          (a) From and after the Closing Date and until the third anniversary
thereof, each Seller (other than any Seller who continues to be employed by the
Company or any Subsidiary on a full-time basis after the Closing) agrees, solely
with respect to itself, not to directly or through a direct or indirect
subsidiary thereof (i) purchase, invest in or fund any FBO at any of the
airports listed in Schedule 7.9, (ii) open for business, invest in, fund or
otherwise assist the establishment of a new FBO at any of the airports listed in
Schedule 7.9, or (iii) solicit or hire any employee of Purchaser or any of its
Affiliates (but, with respect to the employees of the Company or the
Subsidiaries, only those employees of the Company and the Subsidiaries that
accept offers of permanent employment with Purchaser or any of its Affiliates
from and after the Closing); provided, such limitation shall not preclude
Sellers or any of their Affiliates from employing any Person who is no longer
employed by Purchaser or any of its Affiliates at the time such Person contacts
such Seller or Affiliate on his or her own initiative without any direct or
indirect solicitation by or encouragement from Seller or its Affiliates.

          (b) Notwithstanding the foregoing, any Seller may (i) own, solely as
an investment, up to 1.0 % of any class of securities of any Person if such
securities are listed on any national or regional securities exchange so long as
such Seller is not a director, officer, employee or analogously employed or
engaged, (ii) be employed by an entity that has operations that would otherwise
violate Section 7.9(a) if such Seller's position and job function with such
entity does not involve such operations and (iii) be employed by Purchaser or
any of its Affiliates.

          (c) Each Seller specifically acknowledges and agrees that the breach
by such Seller of its covenants contained in this Section 7.9 would cause
Purchaser irreparable harm not compensable solely in damages. Each Seller
acknowledges and agrees that it is essential to the effective enforcement of
this provision that Purchaser be entitled to the remedy of an injunction and it
agrees to the granting of such an injunction, without any showing of damages or
posting of any bond, in the event of a breach by such Seller of the terms of
this provision; provided,


                                       40

<PAGE>

however, that Purchaser shall also be entitled to pursue against such Seller
breaching this Section 7.9 any other remedies (at law or in equity) available to
Purchaser under this Agreement.

          (d) A breach of this Section 7.9 by any particular Seller shall not be
imputed to the other Sellers.

     7.10 NON-SOLICITATION. Purchaser agrees that it shall not, and shall cause
its Affiliates not to, from the date hereof through February 16, 2008, solicit
or hire any employee of the Company or any Subsidiary; provided that such
limitation shall not preclude Purchaser or any of its Affiliates from employing
any Person who is no longer employed by the Company or the Subsidiaries at the
time such Person contacts Purchaser on his or her own initiative without any
direct or indirect solicitation by or encouragement from Purchaser or its
Affiliates. This Section 7.10 shall terminate and have no further force or
effect in the event the Closing occurs.

     7.11 INDEMNIFICATION OF OFFICERS AND DIRECTORS.

          (a) Purchaser agrees that all rights to indemnification for acts or
omissions occurring prior to the Closing Date now existing in favor of the
current or former directors and officers of the Company and the Subsidiaries
currently indemnified by the Company and the Subsidiaries (collectively, the
"COVERED PERSONS") as provided as of the date hereof in their respective Charter
Documents, individual indemnity agreements, board resolutions or otherwise, to
the extent described on Schedule 5.14(d), shall survive the transactions
contemplated herein and shall continue in full force and effect in accordance
with their terms, but solely with respect to claims by Persons other than the
parties to this Agreement, for a period of not less than six years from the
Closing Date. Purchaser and the Company shall not amend, repeal or otherwise
modify such arrangements in any manner that would adversely affect the rights of
the Covered Persons thereunder with respect to indemnification for claims by
Persons other than the parties to this Agreement.

          (b) Purchaser shall cause the Company and the Subsidiaries to honor,
to the fullest extent permitted by applicable Legal Requirements, all of the
Company's obligations and the Subsidiaries' obligations to indemnify (including
any obligations to advance funds for expenses) the Covered Persons for acts or
omissions by such Covered Persons occurring prior to the Closing Date to the
extent that such obligations of the Company exist on the date of this Agreement,
whether pursuant to Charter Documents of the Company or any Subsidiary,
individual indemnity agreements, board resolutions or otherwise, to the extent
described on Schedule 5.14(d), but solely with respect to claims by Persons
other than the parties to this Agreement, and such obligations shall survive the
Closing and shall continue in full force and effect in accordance with the terms
of such arrangements until the expiration of the applicable statute of
limitations with respect to any claims by Persons other than the parties to this
Agreement against such Covered Persons arising out of such acts or omissions;
provided, however, that such indemnification rights shall not apply to any
Covered Person with respect to any liability that such Covered Person is
obligated to indemnify Purchaser or any Purchaser Indemnitee under Section 10.2
of this Agreement.

days after written notice thereof to such other Party prior to the Termination
Date;

          (e) By Purchaser in the event (i) Purchaser is not in breach of this
Agreement and none of its representations and warranties shall have become and
continue to be untrue in a manner that would cause the conditions set forth in
Section 8.2(b) or a failure by Purchaser to perform its covenants in such a
manner as would cause the condition set forth in Section 8.2(a) not to be
satisfied, and (ii) there shall have been a breach of any Seller's or the
Company's representations and warranties in this Agreement or a failure by the
Company to perform its covenants in this Agreement in such a manner that the
conditions to the Closing set forth in Section 8.1(a) or 8.1(b) are not
reasonably likely to be satisfied prior to the later of (A) the Termination Date
or (B) if capable of cure, within ten (10) days after written notice thereof to
such other Party prior to the Termination Date;

          (f) By Purchaser within five Business Days of the Company's delivery
to Purchaser of the Audited 2005 Financial Statements in the event the Audited
EBITDA reflected in the Audited 2005 Financial Statements is less than
$16,141,895; or

          (g) By Purchaser or the Seller Representative in accordance with
Section 7.2(d) or (e).

     9.2 EFFECT OF TERMINATION. In the event of the termination of this
Agreement pursuant to Section 9.1, all obligations of the Parties hereto shall
terminate, except for the provisions of this Section 9.2, and Sections 7.7,
7.10, 10.7, 12.1, 12.2, 12.3, 12.4, 12.5 and 12.9; provided, further, that in
the event this Agreement is terminated pursuant to Section 9.1(b), 9.1(d) or
9.1(e), nothing herein shall prejudice the ability of the non-breaching party
from seeking damages from any other Party for any willful and intentional breach
of this Agreement, including attorneys' fees and the right to pursue any remedy
at law or in equity, and otherwise the Parties shall have no liability to each
other under or relating to this Agreement.

                                 INDEMNIFICATION

     10.1 INDEMNIFICATION BY PURCHASER. Subject to the other terms of this
Article X, from and after the Closing, Purchaser, the Company and the
Subsidiaries shall indemnify, defend and hold harmless each Seller and its
Affiliates and their respective partners, members, directors, officers,
shareholders, employees, successors and assigns (collectively, the "SELLER
INDEMNITEES") from and against any and all damages, claims, liabilities, losses,
costs and expenses (including reasonable fees and expenses of counsel and court
costs) (collectively, "LOSSES") arising out of or resulting from (a) the failure
of any of the representations or warranties made by Purchaser in Article VI to
be true and correct or (b) the failure of Purchaser to perform any of its
covenants or obligations under this Agreement.

     10.2 INDEMNIFICATION BY SECURITYHOLDERS.

          (a) Subject to the other terms of this Article X, from and after the
Closing, each Securityholder shall indemnify, defend and hold harmless Purchaser
and its Affiliates (which shall include the Company and the Subsidiaries after
the Closing) and their respective partners, members, directors, officers,
shareholders, employees, successors and assigns (collectively, the "PURCHASER
INDEMNITEES" and, together with the Seller Indemnitees, the "INDEMNITEES") from
and against any and all Losses arising out of or resulting from (i) the failure
of any of the representations or warranties made by such Securityholder in
Article IV or in the Option Termination Agreement or Warrant Termination
Agreement to be true and correct or (ii) the failure of such Securityholder to
perform any of its obligations, as applicable, under Section 7.9.

          (b) Subject to the other terms of this Article X, from and after the
Closing, the Securityholders shall indemnify, defend and hold harmless the
Purchaser Indemnitees from and against any and all Losses arising out of or
resulting from (i) the failure of the representations and warranties made by the
Company in Article V to be true and correct (provided that each Seller's and the
Company's compliance with the covenants contained in this Agreement on or prior
to the Closing Date shall not result in the failure of such representations and
warranties to be true and correct), (ii) the failure of the Company or any of
the Sellers to perform any of their respective obligations to be performed by
the Company or any Seller under this Agreement (other than the obligations under
Section 7.9), (iii) the ownership or operation of the Non-FBO Assets, (iv) the
matters identified on Schedule 10.2(b)(iv) or (v) any lawsuit first filed
against the Company or any of its Subsidiaries after the Execution Date and
before the Closing Date so long as (A) such lawsuit is brought by, and on behalf
of, a Person that is not a Purchaser Indemnitee and is initiated, maintained and
prosecuted completely independent of any Purchaser Indemnitee and (B) is based
on facts or circumstances unrelated to the matters described on Schedule 5.7.

          (c) Subject to the other terms of this Article X, from and after the
Closing, the Securityholders shall indemnify, defend and hold harmless the
Purchaser Indemnitees from and against any and all fees, Taxes and expenses
arising out of or resulting from the Non-FBO Asset Distribution and, to the
extent the Non-FBO Asset Distribution gives rise to any income Taxes payable by
the Company for the Tax year that includes the Closing Date, effect shall be
given to


                                       47

<PAGE>

all available credits and deductions, including in respect of existing and
future net operating losses and deductions arising from the termination of the
Options for purposes of determining the amount of the Securityholders'
indemnification obligation under this Section 10.2(c). The Parties acknowledge
and agree that no indemnification obligation shall arise under this Section
10.2(c) as a result of any reduction in Tax attributes existing on the Closing
Date that occurs as a result of the Non-FBO Asset Distribution and that makes
such attributes unavailable after the Closing Date.

     10.3 LIMITATIONS AND OTHER INDEMNITY CLAIM MATTERS. Notwithstanding
anything to the contrary in this Agreement, the following terms shall apply to
any claim for monetary damages arising out of this Agreement or related to the
transactions contemplated hereby:

          (a) De Minimis. No Securityholder will have any liability under
Section 10.2(a)(i) (other than with respect to any Claim arising from a breach
by such Securityholder of its representations and warranties under Section 4.1
related to such Seller's title to its Shares), and the Securityholders will not
have any liability under Section 10.2(b)(i) or (v), in respect of any individual
Claim involving Losses to the Purchaser Indemnitees of less than $25,000 (each,
a "DE MINIMIS CLAIM").

          (b) Deductible. No Securityholder will have any liability under
Section 10.2(a)(i) (other than with respect to any Claim under Section 4.1
related to such Securityholder's title to its Shares), and no Securityholder
will have any liability under Section 10.2(b)(i) or (v), in respect of Losses to
the Purchaser Indemnitees until the Purchaser Indemnitees have suffered Losses
in excess of $1,000,000 in the aggregate arising from Claims under Section
10.2(a)(i) and Section 10.2(b)(i) or (v) that are not De Minimis Claims, and
then the Securityholders shall have liability only for such Losses in excess of
$1,000,000.

          (c) Cap. No Securityholder shall have liability under Section
10.2(a)(i) in excess of its percentage interest of the Escrow Funds, which
percentage interest is set forth on Schedule 1 to the Escrow Agreement, except
with respect to any Claim arising from a breach by such Securityholder of its
representations and warranties under Section 4.1 related to such
Securityholder's title to its Shares, which liability shall be limited to the
portion of the Purchase Price actually received by such Securityholder pursuant
to this Agreement. No Securityholder shall have liability under Sections
10.2(b)(i), (ii), (iii), (iv) or (v) or Section 10.2(c) in excess of its
percentage interest of the Escrow Funds, which percentage interest is set forth
on Schedule 1 to the Escrow Agreement.

          (d) Claims Period. In no event shall any Indemnitee be entitled to
assert any Claim under Section 10.1(a), Section 10.2(a)(i) or Sections
10.2(b)(i), (ii), (iii), (iv) or (v) or Section 10.2(c) unless such Claim is
first made on or prior to the eighteen-month anniversary of the Closing Date;
provided, however, that such eighteen-month survival period shall not apply to
any Claim against a particular Securityholder that arises from a breach by such
Securityholder of its representation in Section 4.1 relating to its title to its
Shares, which Claims may be asserted until the expiration of the statute of
limitations applicable thereto.


                                       48

<PAGE>

          (e) Net Working Capital. Notwithstanding anything to the contrary in
this Agreement, the Purchaser Indemnitees shall be deemed not to have suffered
any Losses under Section 10.2 arising from claims based on specific types of
assets and liabilities included in determining the Company's "Net Working
Capital" as of the Closing. It is the Parties' intent that the procedures,
including the dispute resolution procedures, set forth in Section 2.6, shall
provide the sole and exclusive remedies for such claims and that Purchaser shall
not have recourse pursuant to Section 10.2 for breaches of representation and
warranties contained in this Agreement the subject matter of which were settled
pursuant to Section 2.6. By way of illustration, the Parties confirm that the
Company's accounts receivable will be a type of current asset that will be
included in determining the Company's "Net Working Capital" as of the Closing
and, therefore, Purchaser shall not be entitled to seek indemnification from the
Securityholders pursuant to Section 10.2 for a breach of the representations and
warranties in Article V with respect to accounts receivable.

          (f) Exclusive Remedy; Sole Recourse to Escrow Funds.

               (i) Notwithstanding anything to the contrary in this Agreement,
          except (A) as otherwise contemplated by Section 10.3(f)(ii) and (B)
          each Seller's several liability for any breach of Section 4.1 with
          respect to such Seller's title to its Shares, each Securityholder's
          sole and exclusive liability for monetary damages under this
          Agreement, and Purchaser's sole and exclusive recourse for monetary
          damages against any Securityholder, shall be limited to such
          Securityholder's percentage interest of the Escrow Funds, which
          percentage interest is set forth on Schedule 1 to the Escrow
          Agreement, while such funds remain in the Escrow Account. If the
          Closing occurs, the monetary remedies set forth in this Article X and
          the specific performance remedy referenced in Section 12.2 shall
          provide the sole and exclusive remedies arising from this Agreement
          and the transactions contemplated hereby. In the event this Agreement
          is terminated without the occurrence of the Closing, the sole and
          exclusive remedies of the Parties shall be as set forth in Section
          9.2. The Parties acknowledge and agree that the remedies available in
          this Section 10.3(f) supersede any other remedies available at law or
          in equity including rights of rescission and claims arising under
          applicable statutes, including pursuant to Section 27.01 of the Texas
          Business and Commerce Code. The Parties covenant not to sue, assert
          any arbitration claim or otherwise threaten any Claim other than those
          described in this Section 10.3(f) as being available under the
          particular circumstances described in this Section 10.3(f).

               (ii) Nothing in this Agreement (including Section 10.3(f)(i)) is
          intended by the Parties or shall be deemed or otherwise construed to
          limit Purchaser's ability to bring or recover monetary damages for a
          fraud claim under the U. S. Federal securities laws against a
          particular Seller based on that Seller's Knowledge of a misstatement
          of a material fact made by the Company through its representations and
          warranties contained in Article V, as qualified by the Company's
          disclosure schedules. The non-reliance provisions of Section 10.6


                                       49

<PAGE>

          shall not be affected by this Section 10.3(f)(ii). Accordingly, the
          basis of any such fraud claim shall be limited to the specific
          statements covered by the Company's representations and warranties
          contained in Article V. Purchaser's sole and exclusive remedy in
          respect of any such fraud claim under the U.S. Federal securities laws
          against any particular Seller shall be for monetary damages and, with
          respect to such Seller, shall be capped at the portion of the Purchase
          Price actually received by such Seller.

     10.4 CALCULATION OF LOSSES. The amount of any Losses for which
indemnification is provided under this Article X shall be calculated (a) net of
any duplicative amounts recovered by any Indemnitee under insurance policies or
from third Persons with respect to such Losses; (b) net of any Tax Benefit
incurring to any Indemnitee on account of such Loss. If an Indemnitee receives
an amount under insurance coverage or from a third party with respect to Losses
that have been satisfied by a release of any of the Escrow Funds, then such
Indemnitee shall promptly deposit such amount (up to the amount of the Escrow
Funds released for such purpose) into the Escrow Account and such amount shall
be part of the Escrow Funds thereafter; provided, however, than an Indemnitee
shall not be required to deposit into the Escrow Account any released Escrow
Funds to the extent such funds are released to cover the uninsured portion of
any Losses otherwise indemnifiable under this Article X. The amount of any
Losses for which indemnification is provided under this Article X initially
shall be determined without regard to any Tax Benefit. However, to the extent
that the Indemnitee recognizes a Tax Benefit with respect to any payment for
Losses made hereunder, such Indemnitee shall pay to the Indemnitor the amount of
such Tax Benefit (but not in excess of the indemnification payment or payments
actually received from the Indemnitor with respect to such Losses) at such time
or times as and to the extent that the Indemnitee actually realizes such Tax
Benefit through an actual reduction in Tax paid, calculated by computing the
amount of Taxes before and after inclusion of any Tax items attributable to such
Losses for which indemnification was made and treating such Tax items as the
last items claimed for any taxable period; provided that, if any subsequent Tax
adjustments are made relating to the Indemnitee for any taxable period as a
result of or in settlement of any audit or other administrative proceeding that
results in any change in the amount of any Tax Benefit to the Indemnitee,
appropriate payments will be made between the Indemnitor and the Indemnitee to
properly reflect such adjustment amount.

     10.5 CLAIM PROCEDURES.

     (a) Each Indemnitee agrees that promptly after it becomes aware of facts
giving rise to a claim by it for indemnification pursuant to this Article X,
such Indemnitee must assert its claim for indemnification under this Article X
(each, a "CLAIM") by providing a written notice (a "CLAIM NOTICE") to the Person
allegedly required to provide indemnification protection under this Article X
(each, an "INDEMNITOR") specifying, in reasonable detail, the nature and basis
for such Claim (e.g., the underlying representation, warranty or covenant
alleged to have been breached). Notwithstanding the foregoing, an Indemnitee's
failure to send or delay in sending a third party Claim Notice will not relieve
the Indemnitor from liability hereunder with respect to such Claim except to the
extent the Indemnitor is prejudiced by such failure or delay.


                                       50

<PAGE>

     (b) In the event of the assertion of any third party Claim for which, by
the terms hereof, an Indemnitor is obligated to indemnify an Indemnitee, the
Indemnitor will have the right, at such Indemnitor's expense, to assume the
defense of same including the appointment and selection of counsel on behalf of
the Indemnitee so long as such counsel is reasonably acceptable to the
Indemnitee. If the Indemnitor elects to assume the defense of any such third
party Claim, it shall within 30 days notify the Indemnitee in writing of its
intent to do so. Subject to Section 10.5(c), the Indemnitor will have the right
to settle or compromise or take any corrective or remediation action with
respect to any such Claim by all appropriate proceedings, which proceedings will
be diligently prosecuted by the Indemnitor to a final conclusion or settled at
the discretion of the Indemnitor. The Indemnitee will be entitled, at its own
cost, to participate with the Indemnitor in the defense of any such Claim. If
the Indemnitor assumes the defense of any such third-party Claim but fails to
diligently prosecute such Claim, or if the Indemnitor does not assume the
defense of any such Claim, the Indemnitee may assume control of such defense and
in the event it is finally determined by a court of competent jurisdiction that
the Claim was a matter for which the Indemnitor is required to provide
indemnification under the terms of this Article X, the Indemnitor will bear the
reasonable costs and expenses of such defense (including fees and expenses of
counsel).

     (c) Notwithstanding anything to the contrary in this Agreement, the
Indemnitor will not be permitted to settle, compromise, take any corrective or
remedial action or enter into an agreed judgment or consent decree, in each
case, that subjects the Indemnitee to any criminal liability, requires an
admission of guilt or wrongdoing on the part of the Indemnitee or imposes any
continuing obligation on or requires any payment from the Indemnitee without the
Indemnitee's prior written consent.

     10.6 NO RELIANCE.

          (a) Limited Representations and Warranties. THE REPRESENTATIONS AND
WARRANTIES OF EACH SELLER CONTAINED IN ARTICLE IV AND THE COMPANY CONTAINED IN
ARTICLE V CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF
SELLERS AND THE COMPANY, AS APPLICABLE, TO PURCHASER IN CONNECTION WITH THE

OR ANY OF THEIR AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR

ON, ANY INFORMATION, DOCUMENTS OR OTHER MATERIAL MADE AVAILABLE TO PURCHASER IN
ANY DATA ROOM, MANAGEMENT PRESENTATION OR IN ANY OTHER FORM IN EXPECTATION OF,
OR IN CONNECTION WITH, THE TRANSACTIONS CONTEMPLATED HEREBY). EXCEPT FOR SUCH
REPRESENTATIONS AND WARRANTIES (IN EACH CASE, AS MODIFIED BY THE SCHEDULES
HERETO), EACH PARTY HEREBY DISCLAIMS ALL LIABILITY AND RESPONSIBILITY FOR ANY

REPRESENTATIVE OF SUCH PARTY OR ANY OF ITS AFFILIATES). PURCHASER ACKNOWLEDGES
AND AGREES THAT IT HAS NOT RELIED, INCLUDING FOR PURPOSES OF SECTION 27.01 OF
THE TEXAS BUSINESS AND COMMERCE CODE, ON ANY REPRESENTATIONS AND WARRANTIES
OTHER THAN THE EXPRESS REPRESENTATIONS AND WARRANTIES SET FORTH IN THIS
AGREEMENT IN MAKING ITS INVESTMENT DECISION WITH RESPECT TO THE SHARES.

          (b) Covenant Not to Sue. Neither Purchaser nor any of its Affiliates
(including any Purchaser Indemnitee) shall assert or threaten, and Purchaser
hereby waives and shall cause such Affiliates to waive, any claim or other
method of recovery, in contract, in tort or under applicable Legal Requirements,
including Section 27.01 of the Texas Business and Commerce Code, against any
Person that is not a party hereto (or a successor to a party hereto) relating to
the transactions contemplated by this Agreement or the distribution of the
Purchase Price or the Escrow Funds.

          (c) Waiver of Consequential Damages, Etc. In no event shall any Party
be liable for (and the term "Losses" shall exclude) any consequential (including
lost profits), punitive or exemplary damages alleged to have resulted from a
breach by any Party of any provision of this Agreement or the other Transaction
Documents or related hereto or thereto, and in no event shall an arbitrator be
able to award such damages unless, and solely to the extent that, a Party hereto
becomes obligated to pay such damages to a third party.

     10.7 DISPUTE RESOLUTION. Any controversy, dispute or claim arising out of
or relating to this Agreement or the Transaction Documents, including but not
limited to a claim based on or arising from an alleged tort or the performance,
enforcement, breach, termination, statute of limitations applicable, scope or
validity thereof ("DISPUTE") for which application for immediate injunctive
relief shall be available, shall be submitted first to mediation to be conducted
in New York, New York and administered by the American Arbitration Association
("AAA") under its Commercial Mediation Rules before resorting to arbitration.

          (a) If the Dispute is not resolved within 30 days after the request
for mediation, any unresolved Dispute shall be settled by binding arbitration.
The arbitration shall


                                       52

<PAGE>

be conducted in New York, New York before a single arbitrator being a retired
judge of the state or federal courts located in the State of New York. If the
Parties are unable to agree on selection of an arbitrator, shall be selected
under the expedited rules of the AAA. The rules of the AAA shall apply to the
extent not inconsistent with the rules herein specified. Either Seller
Representative on behalf of Sellers or Purchaser may initiate arbitration by
written notice to the other party and the arbitration will be conducted
according to the following: (i) not later than seven (7) days prior to the
hearing date set by the arbitrator, each party shall submit a brief with a
single proposal for settlement, (ii) the hearing will be conducted on a
confidential basis without continuance or adjournment, (iii) the arbitrator will
be limited to selecting only one of the two proposals submitted by the parties,
and (iv) evidence concerning the financial position or organizational makeup of
the parties, any offer made or the details of any negotiation prior to
arbitration shall not be permissible. Judgment on the award rendered by the
arbitrator may be entered in any court having jurisdiction thereof. The award
shall be in writing, shall be signed by the arbitrator and shall include
findings of fact and a statement of the reasons for the award with a breakdown
as to specific claims. If at any time the Parties resolve their Dispute, then,
notwithstanding the provisions of this Section 10.7, the arbitration procedures
will promptly be discontinued. Such resolution will be final and binding on the
Parties.

          (b) Any party may, without waiving any remedy of arbitration, seek
from a court or agency having jurisdiction, any interim, equitable or
provisional relief to protect the property or rights of that party pending the
arbitrator's determination of the merits of the Dispute, but without award of
attorneys' fees, costs and expenses as set forth in Section 10.7(d).

          (c) The arbitration award shall be made within three months of the
filing of the notice of intention to arbitrate, and the arbitrator shall agree
to comply with this schedule before accepting appointment.

          (d) The costs and expenses of the arbitrator shall be borne
proportionately by the Parties based on the resolution of the Dispute by the
arbitrator. Such proportionate sharing of expenses will be determined based on
the arbitrator's final resolution of the Dispute.

          (e) Except as may be required by law, neither the Parties nor the
arbitrator shall disclose the existence, content or results of any arbitration
without the prior written consent of the other Parties.

                                   ARTICLE XI
                                   [RESERVED.]

                                   ARTICLE XII
                                     GENERAL

     12.1 ENTIRE AGREEMENT; SUCCESSORS AND ASSIGNS.

          (a) Except for documents and agreements executed pursuant hereto, and
except for the provisions of the Confidentiality Agreement, this Agreement
supersedes all prior oral discussions and written agreements among the Parties
with respect to the subject matter of


                                       53

<PAGE>

this Agreement (including the Memorandum of Understanding dated February 16,
2006 and any other term sheet or similar agreement or document relating to the
transactions contemplated hereby). Except for the Confidentiality Agreement,
this Agreement, including the exhibits and schedules hereto and other documents
delivered in connection herewith, contains the sole and entire agreement between
the Parties hereto with respect to the subject matter hereof. The
Confidentiality Agreement shall terminate and be of no further force or effect
in the event that the Closing occurs.

          (b) All of the terms, covenants, representations, warranties and
conditions of this Agreement will be binding upon, and inure to the benefit of,
and be enforceable by, the Parties and their respective successors and permitted
assigns (and in the case of indemnities to the benefit of all persons
indemnified). Nothing herein expressed or implied is intended or will be
construed to confer upon or to give any Person not a Party any rights or
remedies under or by reason of this Agreement, except for the indemnified
parties expressly identified in this Agreement.

          (c) Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assignable by (i) the Company or any Seller
without the prior written consent of Purchaser or (ii) Purchaser without the
prior written consent of the Seller Representative; provided, however, that
Purchaser may, upon written notice to the Seller Representative, assign in whole
its right, title and interest under this Agreement to North America Capital
Holding Company, but such assignment shall not release Purchaser from its
obligations hereunder.

     12.2 SPECIFIC PERFORMANCE. Each Party acknowledges that the remedies at law
of the Parties for a breach or threatened breach of this Agreement would be
inadequate and, in recognition of this fact, any Party, without posting any
bond, and in addition to all other remedies that may be available, shall be
entitled to obtain equitable relief in the form of specific performance, a
temporary restraining order, a temporary or permanent injunction or any other
equitable remedy that may then be available.

     12.3 AMENDMENTS. This Agreement may be amended, modified or superseded, and
any of the terms, covenants, representations, warranties or conditions hereof
may be waived, only by a written instrument executed by Purchaser and Seller
Representative or, in the case of a waiver, by or on behalf of Purchaser (if
Purchaser is waiving compliance) or Seller Representative (if any Seller is
waiving compliance). The failure of any Party at any time or times to require
performance of any provisions hereof will in no manner affect the right at a
later time to enforce the same. No waiver by any Party of any condition, or of
any breach of any term, covenant, representation or warranty contained in this
Agreement, in any one or more instances, will be deemed to be or construed as a
further or continuing waiver of any such condition or breach or a waiver of any
other condition or of any breach of any other term, covenant, representation or
warranty.

     12.4 NOTICES. Unless otherwise provided herein, all notices, requests,
consents, approvals, demands and other communications to be given hereunder
(collectively, "NOTICES") will be in writing and will be deemed given upon (a)
confirmation of receipt of a facsimile transmission, (b) confirmed delivery by a
standard overnight carrier or when delivered by hand,
