Commercial Lease concerning: 1611 Wilmeth Rd.                     1611
-------------------------------------------------------------------------------

         D.   Place of Payment: Tenant will remit all amounts due Landlord under
              this lease to Royce Smith at PO BOX 2770 McKinney, Texas 75069 or
              to such other person or at such other place as Landlord may
              designate in writing.

         E.   Method of Payment: Tenant must pay all rent timely without demand,
              deduction, or offset, except as permitted by law or this lease.
              Time is of the essence for the payment of rent. If Tenant fails to
              timely pay any amounts due under this lease or if any check of
              Tenant is returned to Landlord by the institution on which it was
              drawn, Landlord may require Tenant to pay, in addition to any
              other available remedy, all amounts due under this lease by
              certified funds by providing written notice to Tenant.

         F.   Late Charges: If Landlord does not actually receive a rent payment
              at the designated place of payment within 10 days after the date
              the rent is due. The mailbox is not the agent for receipt for
              Landlord. The late charge is a cost associated with the collection
              of rent and Landlord's acceptance of a late charge does not waive
              Landlord's rights to exercise remedies under Paragraph 20. LATE
              CHARGE $30 a day.

         G.   Returned Checks: Tenant will pay $25.00 (not to exceed $25) for
              each check Tenant tenders to Landlord which is returned by the
              institution on which it is drawn for any reason, plus any late
              charges until Landlord receives payment.

5.       SECURITY DEPOSIT: Upon execution of this lease, Tenant will pay a
         security deposit to Landlord in the amount of $17,400.00 Landlord may
         apply the security deposit to any amounts owed by Tenant under this
         lease. If Landlord applies any part of the security deposit during any
         time this lease is in effect to amounts owed by Tenant, Tenant must,
         within 10 days after receipt of notice from Landlord, restore the
         security deposit to the amount stated. Within a reasonable time after
         this lease ends, Landlord will refund the security deposit to Tenant
         less any amounts applied toward amounts owed by Tenant.

6.       TAXES: Unless otherwise agreed by the parties, Tenant will pay all real
         property ad valorem taxes assessed against the leased premises.

7.       UTILITIES: Tenant will pay all charges for the use of all utility
         services to the leased premises and any connection charges except the
         following which will be paid by Landlord: N/A
         NOTICE: Tenant should determine if any and all necessary utilities
         (e.g., water, gas, electricity, telephone, sewer, etc.) are available
         to the leased premises, are adequate for Tenant's intended use, and the
         cost to provide the necessary utilities.

8.       TENANT'S INSURANCE:

         A.   During all times this lease is in effect, Tenant must maintain in
              full force and effect:

              (1)    public liability insurance from an insurer acceptable to
                     Landlord in an amount not less than $1,000,000.00 on an
                     occurrence basis naming Landlord as an additional insured;
                     and

              (2)    personal property damage insurance for Tenant's business
                     operations on the leased premises from an insurer
                     acceptable to Landlord in an amount not less than
                     $1,000,000.00 on an occurrence basis.

         B.   Before the Commencement Date, Tenant must provide Landlord with a
              copy of the insurance certificates evidencing the required
              coverage. If the insurance coverage changes in any manner or
              degree at any time this lease is in effect, Tenant must provide
              Landlord a copy of an insurance certificate evidencing such change
              within 10 days of the change.

         C.   If Tenant fails to maintain the required insurance in full force
              and effect at all times this lease is in effect, Landlord may: (1)

              immediately reimburse Landlord for such expense; or (2) exercise
              Landlord's remedies under Paragraph 20.

         D.   If there is an increase in Landlord's insurance premiums for the
              leased premises or Property or its contents that is caused by
              Tenant, Tenant's use of the leased premises, or any improvements
              made by or for Tenant, Tenant will, for each year this lease is in
              effect, pay Landlord the increase immediately after Landlord
              notifies Tenant of the increase.

9.       USE AND HOURS: Tenant may use the leased premises for the following
         purpose and no other: General Office, Warehouse, and Assembly Work.

Commercial Lease concerning: 1611 Wilmeth Rd.                     1611
-------------------------------------------------------------------------------

         E.   HVAC Service Contract: If Tenant is responsible to maintain the
              HVAC system, Tenant [ ] is [X] is not required to maintain, at its
              expense, a regularly scheduled maintenance and service contract
              for the HVAC system. The maintenance and service contract must be
              purchased from a HVAC maintenance company that regularly provides
              such contracts to similar properties. If Tenant fails to maintain
              a required HVAC maintenance and service contract in effect at all
              times during this lease, Landlord may do so and charge Tenant the
              expense of such a maintenance and service contract or exercise
              Landlord's remedies under Paragraph 20.

         F.

         G.   Notice of Repairs: Tenant must promptly notify Landlord of any
              item that is in need of repair and that is Landlord's
              responsibility to repair. All requests for repairs to Landlord
              must be in writing.

         H.   Failure to Repair: Landlord must make a repair for which Landlord
              is responsible within a reasonable period of time after Tenant
              provides Landlord written notice of the needed repair. If Tenant
              fails to repair or maintain an item for which Tenant is
              responsible within 10 days after Landlord provides Tenant written
              notice of the needed repair or maintenance, Landlord may: (1)
              repair or maintain the item, without liability for any damage or
              loss to Tenant, and Tenant must immediately reimburse Landlord for
              the cost to repair or maintain; or (2) exercise Landlord's
              remedies under Paragraph 20.

16.      ALTERATIONS:

         A.   Tenant may not alter, improve, or add to the Property or the
              leased premises without Landlord's written consent. Landlord will
              not unreasonably withhold consent for the Tenant to make
              reasonable alterations, modifications, or improvements to the
              leased premises.

         B.   Tenant may not alter any locks or any security devices on the
              Property or the leased premises without Landlord's consent. If
              Landlord authorizes the changing, addition, or rekeying of any
              locks or other security devices, Tenant must immediately deliver
              the new keys and access devices to Landlord.

         C.   If a governmental order requires alteration or modification to the
              leased premises, the party obligated to maintain and repair the
              item to be modified or altered as designated in Paragraph 15 will,
              at its expense, modify or alter the item in compliance with the
              order.

         D.   Any alterations, improvements, fixtures or additions to the
              Property or leased premises installed by either party during the
              term of this lease will become Landlord's property and must be
              surrendered to Landlord at the time this lease ends, except for
              those fixtures Landlord requires Tenant to remove under Paragraph
              14 or if the parties agree otherwise in writing.

17.      LIENS: Tenant may not do anything that will cause the title of the
         Property or leased premises to be encumbered in any way. If Tenant
         causes a lien to be filed against the Property or leased premises,
         Tenant will within 20 days after Landlord demands Tenant to take action
         to remove the lien, pay the lien or take whatever action is necessary
         to cause the lien to be released of record. Tenant will provide
         Landlord a copy of any release Tenant obtains pursuant to this
         paragraph.

18.      LIABILITY: To the extent Permitted by law, Landlord is NOT responsible
         to Tenant or Tenant's employees, patrons, guests, or invitees for any
         damages, injuries, or losses to person or Property caused by:

         A.   an act, omission, or neglect of: Tenant; Tenant's agent; Tenant's
              quest; Tenant's employees; Tenant's patrons; Tenant's invitees; or
              any other tenant on the Property;

         B.   fire, flood, water leaks, ice, snow, hail, winds, explosion,
              smoke, riot, strike, interruption of utilities, theft, burglary,
              robbery, assault, vandalism, other persons, environmental
              contaminants, or other occurrences or casualty losses.

19.      INDEMNITY: Tenant will indemnify and hold Landlord harmless from any
         Property damage, personal injury, suits, actions, liabilities, damages,
         cost of repairs or service to the leased premises or Property, or any
         other loss caused, negligently or otherwise, by Tenant or Tenant's
         employees, patrons, guests, or invitees.

20.      DEFAULT:

         A.   If Landlord fails to comply with this lease within 30 days after
              Tenant notifies Landlord of Landlord's failure to comply, Landlord
              will be in default and Tenant may seek any remedy provided by law.
              If, however, Landlord's non-compliance reasonably requires more
              than 30 days to cure, Landlord will not in default if the cure is
              commenced within the 30 day period and is diligently pursued.

Commercial Lease concerning: 1611 Wilmeth Rd.                     1611
-------------------------------------------------------------------------------

         B.   If Landlord does not actually receive at the place designated for
              payment any rent due under this lease within days after it is due,
              Tenant will be in default. If Tenant fails to comply with this
              lease for any other reason within 10 days after Landlord notifies
              Tenant of its failure to comply, Tenant will be in default.

         C.   If Tenant is in-default, Landlord may: (i) terminate Tenant's
              right to occupy the leased premises by providing Tenant with at
              least 3 days written notice; and (ii) accelerate all rents which
              are payable during the remainder of this lease or any renewal
              period without notice or demand. Landlord will attempt to mitigate
              any damage or loss caused by Tenant's breach. If Tenant is in
              default, Tenant will be liable for:

              (1)    any lost rent;

              (2)    Landlord's cost of reletting the leased premises, including
                     brokerage fees, advertising fees, and other fees necessary
                     to relet the leased premises;

              (3)    repairs to the leased premises for use beyond normal wear
                     and tear;

              (4)    all Landlord's costs associated with eviction of Tenant,
                     such as attorney's fees, court costs, and prejudgment
                     interest;

              (5)    all Landlord's costs associated with collection of rent
                     such as collection fees, late charges, and returned check
                     charges;

              (6)    cost of removing any equipment and trade-fixtures left on
                     the leased premises by Tenant;

              (7)    cost to remove any trash, debris, personal property,
                     hazardous materials, or environmental contaminants left by
                     Tenant or Tenant's employees, patrons, guests, or invitees
                     in the leased premises or Property; and

              (8)    any other recovery to which Landlord may be entitled by
                     law.

21.      ABANDONMENT, INTERRUPTION OF UTILITIES, REMOVAL OF TENANT'S PROPERTY,
         AND LOCKOUT: Chapter 93 of the Texas Property Code governs the rights
         and obligations of the parties with regard to: (a) abandonment of the
         leased premises; (b) interruption of utilities; (c) removal of Tenant's
         personal property; and (d) "lock-out" of Tenant.

22.      HOLDOVER: If Tenant fails to vacate the leased premises at the time
         this lease ends, Tenant will become a tenant-at-will and must vacate
         the leased premises immediately upon receipt of demand from Landlord.
         No holding over by Tenant, with or without the consent of Landlord,
         will extend this lease. Tenant will indemnify Landlord and any
         prospective tenants for any and all damages caused by the holdover.
         Rent for any holdover period will be the base monthly rent.

23.      LANDLORD'S LIEN AND SECURITY INTEREST: To secure Tenant's performance
         under this lease, Tenant grants to Landlord a lien and security
         interest against all of Tenant's nonexempt personal property that is in
         the leased premises or Property. This lease is a security agreement for
         the purposes of the Uniform Commercial Code. Landlord may file a copy
         of this lease as a financing statement.

24.      ASSIGNMENT AND SUBLETTING: Tenant may not assign this lease or sublet
         any part of the leased premises without Landlord's written consent. An
         assignment of this lease or subletting of the leased premises Without
         Landlord's written consent is voidable by Landlord. If Tenant assigns
         this lease or sublets any part of the leased premises, Tenant will
         remain liable for all of Tenant's obligations under this lease
         regardless if the assignment or sublease is made with or without the
         consent of Landlord.

25.

26.      SUBORDINATION:

         A.   This lease and Tenant's leasehold interest are and will be
              subject, subordinate, and inferior to:

                     placed on the leased premises or the Property by Landlord;

                     ground lease;

              (3)    the interest payable on any such lien or encumbrance;

              (4)    any and all renewals and extensions of any such lien,
                     encumbrance, or ground lease;

              (5)    any restrictive covenant affecting the leased premises or
                     the Property; and

              (6)    the rights of any owners' association affecting the leased
                     premises or Property.

         B.   Tenant must, on demand, execute any instrument subordinating this
              lease as Landlord may request, provided that such subordination is
              made on the condition that this lease and Tenant's rights under
              this lease are recognized by the lien-holder.

27.      ESTOPPEL CERTIFICATES: Within 10 days after receipt of a written
         request from Landlord, Tenant will execute and deliver to Landlord an
         estoppel certificate that identifies: (a) when this lease commences and
         ends; (b) any amendments to this lease; (c)

28.      CASUALTY LOSS:

         A.   Tenant must immediately notify Landlord of any casualty loss in

              leased premises are less than or more than 50% unusable, on a per
              square foot basis, and if Landlord can substantially restore the
              leased premises within 120 days after Tenant notifies Landlord of
              the casualty loss.

         B.   If the leased premises are less than 50% unusable and Landlord can
              substantially restore the leased premises within 120 days after
              Tenant notifies Landlord of the casualty, Landlord will restore
              the leased promises to substantially the same condition as before
              the casualty. If Landlord fails to substantially restore within
              the time required, Tenant may terminate this lease.

         C.   If the leased premises are more than 50% unusable and Landlord can
              substantially restore the leased premises within 120 days after
              Tenant notifies Landlord of the casualty, Landlord may: (1)
              terminate this lease; or (2) restore the leased premises to
              substantially the same condition as before the casualty. If
              Landlord chooses to restore and does not substantially restore the
              leased premises within the time required, Tenant may terminate
              this lease.

         D.   If Landlord notifies Tenant that Landlord cannot substantially
              restore the leased premises within 120 days after Tenant notifies
              Landlord of the casualty loss, Landlord may: (1) choose not to
              restore and terminate this lease; or (2) choose to restore, notify
              Tenant of the estimated time to restore, and give Tenant the
              option to terminate this lease by notifying Landlord within 10
              days.

         E.   If this lease does not terminate because of a casualty loss, rent
              will be reduced from the date Tenant notifies Landlord of the
              casualty loss to the date the leased premises are substantially
              restored by an amount proportionate to the extent the leased
              premises are unusable.

29.      CONDEMNATION: If after a condemnation or purchase in lieu of
         condemnation the leased premises are totally unusable for the purposes
         stated in this lease, this lease will terminate. If after a
         condemnation or purchase in lieu of condemnation the leased premises
         are partially unusable for the purposes stated in this lease, this
         lease will continue and rent will be reduced in an amount proportionate
         to the extent the leased premises are unusable. Any condemnation award
         or proceeds in lieu of condemnation are the property of Landlord and
         Tenant has no claim to such proceeds or award. Tenant may seek
         compensation from the condemning authority for its moving expenses and
         damages to Tenant's personal property.

         proceeding brought under or related to the transaction described in

         attorney's fees, and all other costs of litigation from the
         nonprevailing party.

         for rental are material representations relied upon by Landlord. Each
         party signing this lease represents that he or she is of legal age to
         enter into a binding contract and is authorized to sign the lease. If
         Tenant makes any misrepresentation in this lease or in any application

                              SETTLEMENT AGREEMENT

         This Settlement Agreement (the "Agreement") is made effective as of the
___ day of September, 2000, by and between AAROW Environmental Group, Inc., a
Nevada corporation a/k/a AARO Broadband Wireless Communications Corporation
("AARO Broadband"), Getmore Communications, Inc., an Oklahoma corporation
("Getmore"), GKD, Inc., an Oklahoma corporation ("GKD"), Ronald L. Baker, an
individual ("Baker"), Gary Duke, an individual ("Duke") (collectively, "AARO");
Broadband Wireless International Corporation, f/k/a Black Giant Oil Company, a
Nevada corporation ("Broadband"), by and through Peter Bradford, Esq., duly
appointed Receiver for Broadband by United States District Judge Tim Leonard on
August 11, 2000, in Case No. CIV-00-1375, United States District Court, Western
District of Oklahoma, pursuant to an Order Appointing Temporary Receiver entered
same date (the "Receiver Order"); and Ivan Webb, an individual ("Webb")
(collectively, "BBAN"); and BroadCom Wireless Communications Corporation, a/k/a
BroadCom Communications Group, a/k/a Broadband Wireless Communications
Corporation, an Oklahoma corporation ("BroadCom") by and through Peter Bradford,
Esq., duly appointed Receiver for Broadband by United States District Judge Tim
Leonard on August 11, 2000, pursuant to the Receiver Order; and Black Giant

through Peter Bradford, Esq., duly appointed Receiver for Broadband by United

Order; and each of the Purchasers identified in Section 2.1 hereof (the "Stipe
Group").

                     I. HISTORY AND PURPOSE OF THE AGREEMENT

                  1.1 Beginning in 1999, Getmore, GKD, Baker, and Duke in good
faith entered into numerous different written and oral agreements with BBAN,
BroadCom, Black Giant Resources and others for the purpose of creating and
funding businesses proficient in high speed internet and wireless related
services. Getmore, GKD, Baker, and Duke have alleged in the various civil
actions hereinafter identified that BBAN, BroadCom, Black Giant Resources and
others breached those agreements. As a result of those alleged breaches of
agreements, Baker in good faith rescinded his agreements with BBAN, BroadCom,
Black Giant Resources and others.

                  1.2 The United States Securities and Exchange Commission
initiated a civil action on August 11, 2000, in the United States District
Court, Western District of Oklahoma, Case No. CIV-00-1375, against BBAN,
BroadCom, Black Giant Resources, Webb and others for alleged violations of the
Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as
amended. The District Court issued in that civil action on August 11, 2000, a
Temporary Restraining Order, Asset Freeze and Order Requiring Accountings,
Prohibiting Destruction and Alteration of Documents. At the same time, the
District Court entered an Order Appointing Temporary Receiver.

                  1.3 It is the purpose of this Agreement to accomplish a
complete and final settlement of all claims, demands, differences and causes of
action between AARO, Getmore, GKD, Baker, Duke, BBAN, BroadCom, Black Giant
Resources, the Stipe Group and each of the officers, directors, agents,
employees, representatives, and shareholders thereof, with respect to the
disputes described below.

                            III. TERMS OF SETTLEMENT

                  In consideration of the mutual covenants as set forth herein,
the parties hereto agree as follows:

                  3.1 Purchase and Assignment of Claims of Broadband. AARO shall
forthwith begin soliciting purchasers (the "Assigned Claims Purchasers") for the
asserted and unasserted claims of Broadband in the First Civil Action, Second
Civil Action and Third Civil Action as against Baker, AARO Broadband, Getmore,
GKD and Duke (the "Assigned Claims"). The Assigned Claims Purchasers shall be
identified on or before the hearing date for approval of this Settlement
Agreement by the United States District Court for the Western District of
Oklahoma ("Approval Hearing") pursuant to Section 3.1.4 hereof. The aggregate
purchase price for the Assigned Claims shall be $400,000.00 ("Purchase Price").
The terms of the purchase of the Assigned Claims shall be $200,000.00 payable to
the Escrow Agent (as defined in Section 3.2 hereof) on or before the Approval
Hearing, and the remaining $200.000.00 shall be paid to the Receiver within
sixty (60) days after the Approval Hearing. If, however, the Assigned Claims
Purchasers do not pay the remaining $200,000.00, then AARO shall pay the
$200,000.00 to the Receiver on or before sixty (60) days after the Approval
Hearing. Such solicitations by AARO shall be made solely on a non-public basis,
and shall be made solely to "accredited investors," as

                                       3
<PAGE>   4

that term is defined in Rule 501(a) of Regulation D under the Securities Act of
1933, as Solicitations for Assigned Claims Purchasers may only be made by duly
authorized officers and/or directors of AARO and no direct remuneration for such
sales shall be paid by AARO, the Receiver, the Assigned Claims Purchasers or any
other person to such officers and/or directors. All Assigned Claims Purchasers
shall be required to execute such subscriptions documents and assignment of
claims agreements as shall be reasonably required by AARO Broadband and the
Receiver, respectively, and all such documentation and the consummation of the
transactions contemplated hereby shall be contingent upon the approval of this
Agreement by the United States District Court for the Western District of
Oklahoma.

                  3.2 Escrow of Settlement Stock, New Warrants and Cash. Upon
execution of this Agreement, AARO Broadband shall promptly cause to be delivered
to MidFirst Bank ("Escrow Agent"), as the escrow agent for Receiver, an
aggregate of 3,000,000 shares of duly authorized, but unissued AARO common
stock, $.001 par value per share (the "Settlement Stock"). Upon execution of
this Agreement, AARO Broadband shall further promptly cause to be delivered to
The Escrow Agent 1,399,998 new warrants, the attributes of which shall be
identical in form and substance to the Restricted Warrants identified in Section
2.2 hereof (the "New Warrants"). The Escrow Agent shall accept and hold pursuant
to the terms of this Agreement: (i) the Settlement Stock; (ii) the New Warrants;
and (iii) all of the funds paid by the Assigned Claims Purchasers pursuant to
Section 3.1 hereof.

                  3.3 Court Approval of Settlement Agreement. Promptly upon
execution of this agreement by all parties hereto, the Receiver, AARO and Baker
shall undertake to obtain the approval of the terms and conditions of this
Agreement in accordance with the Order Approving Temporary Receiver dated August
11, 2000, and provisions of Section 3(a)(10) of the 1933 Act, such that the
Settlement Stock may be sold by the Receiver to the Subscribers without
restriction under the 1933 Act.

                  3.4 Attributes of Settlement Stock and New Warrants. Upon
entry of an appropriate court order approving the terms and conditions of this
Agreement as set forth in Sections 3.1 and 3.2, above, the Settlement Stock and
New Warrants shall be deemed to be free-trading stock exempt from registration
pursuant to Section 3(a)(10) of the 1933 Act.

                  3.5 Cash Payments. Upon entry of an appropriate court order
approving the terms and conditions of this Agreement as set forth in Sections
3.1, 3.2 and 3.3, above, the Escrow Agent shall: (i) release the cash proceeds
received from the Assigned Claim Purchasers to the Receiver; and (ii) release
the Settlement Stock to the Assigned Claims Purchasers. In the event that, for
any reason the United States District Court does not approve the terms and
conditions of this Agreement pursuant to Section 3.3 hereof, the Escrow Agent
shall return the Settlement Stock to AARO Broadband and return the money paid by
the Assigned Claims Purchasers.

                  3.6 Return of Certain BBAN Stock of Baker and Duke. Pursuant
to various agreements entered into between BroadCom, Getmore, GKD, Baker and
Duke, Baker and Duke

upon approval of this Agreement by the District Court and payment of the full
Purchase Price, Baker and Duke shall take all steps necessary to cause to be
delivered to BBAN physical possession of 2,700,000 such shares of common stock,
and the Escrow Agent shall distribute 200,000 shares of the Settlement Stock to

Restricted Warrants. In consideration of the cancellation of said Restricted
Warrants by AARO Broadband, the Escrow Agent shall release 1,400,000 New
Warrants to the Restricted Warrant Holders based upon their proportionate share
of ownership in the Restricted Warrants as set forth in Section 2.2 hereof.
