        COMMUNICATION, INC., a
        Nevada
        corporation, whose address is 8600 Wurzbach, Suite 700W, San Antonio, Texas
        78240 (“Maker”),
        for
        value received, promises to pay to the order of CSI
        BUSINESS FINANCE, INC.
        (“Payee”),
        in
        lawful money of the United States of America, the principal sum of FIFTY
        THOUSAND AND NO/100 DOLLARS ($50,000.00). All principal and any interest
        hereunder shall be payable at
        109
        North Post Oak Lane, Suite 422, Houston, Harris County,
        Texas 77024,
        or such
        other place that Payee may hereafter designate in writing.

      

      This
        promissory
        note (the “Note”)
        shall be
        due and payable upon the sooner to occur of demand or November 4, 2006. Accrued
        and unpaid interest on the principal amount outstanding hereunder shall be
        payable on the last day of each month. Interest
        shall accrue on the unpaid amounts hereunder at the lesser of eighteen percent
        (18%) per annum or the maximum rate allowed by law. All interest that shall
        accrue in accordance herewith on the indebtedness evidenced by this Note
        shall
        be computed on the basis of a year of 365 or 366 days, as the case may
        be.

       

      Each
        of
        the following events shall be herein referred to as an "Event
        of Default":
        (i)
        the failure of Maker to make payment of any of the principal or interest
        hereunder when due; (ii) any default by Maker of any of its obligations under
        the Security Agreement (hereinafter defined), or any other instrument or
        agreement that secures the repayment of this Note; (iii) the filing of a
        petition in bankruptcy by or relating to Maker; (iv) the assignment of assets
        for the benefit of creditors of Maker; (v) any default by Maker under that
        certain Factoring Agreement (the "Factoring
        Agreement"),
        executed or to be executed by Maker and Payee; and (vi) the termination of
        the
        factoring relationship between Payee and Maker under the Factoring Agreement.
        It
        is especially agreed that upon the occurrence of an Event of Default, Payee
        or
        any other holder hereof at any time thereafter may, at its option, (a) declare
        the entire unpaid principal of and accrued interest on this Note immediately
        due
        and payable without notice, demand or presentment, all of which are hereby
        waived, and upon such declaration, the same shall become and shall be
        immediately due and payable, and (b) take any and all other actions available
        to
        Payee or any holder under this Note at law, in equity or otherwise. The failure
        of the holder hereof to exercise any of the foregoing options shall not
        constitute a waiver of the right to exercise the same upon the occurrence
        of a
        subsequent default. 

      

      
        
          
          

        

        
          -1-

          
            

          

        

        
          
          

        

      

      It
        is the
        intention of the parties hereto to conform strictly to applicable usury laws
        as
        in effect from time to time during the term of this Note. Accordingly, if
        any
        transaction or transactions contemplated hereby would be usurious under
        applicable law (including the laws of the United States of America, or of
        any
        other jurisdiction whose laws may be mandatorily applicable), then, in that
        event, notwithstanding anything to the contrary in this Note, it is agreed
        as
        follows: (i) the provisions of this paragraph shall govern and control; (ii)
        the
        aggregate of all interest under applicable laws that is contracted for, charged
        or received under this Note shall under no circumstances exceed the maximum
        amount of interest allowed by applicable law, and any excess shall be promptly
        credited to Maker by Payee (or, if such consideration shall have been paid
        in
        full, such excess shall be promptly refunded to Maker by Payee); (iii) neither
        Maker nor any other person or entity now or hereafter liable in connection
        with
        this Note shall be obligated to pay the amount of such interest to the extent
        that it is in excess of the maximum interest permitted by the applicable
        usury
        laws; and (iv) the effective rate of interest shall be ipso facto
        reduced
        to the maximum lawful interest rate.

      

      Maker
        shall have the privilege to prepay this Note at any time, and from time to
        time,
        in whole or in part, without penalty or fee. Any prepayment of principal
        under
        this Note shall include accrued interest to the date of prepayment on the
        total
        outstanding principal balance at the time such prepayment is made.

      

      
        
          
          

        

        
          -2-

          
            

          

        

        
          
          

        

      

      Maker
        and
        any other co-makers, endorsers, guarantors and sureties severally (i) waive
        notice (including, but not limited to, notice of protest, notice of dishonor
        and
        notice of intent to accelerate or notice of acceleration), demand, presentment
        of payment, protest and filing of suit for the purpose of fixing liability,
        (ii)
        consent that the time of payment hereof may be extended without notice to
        them
        or any of them, (iii) expressly agree that it will not be necessary for any
        holder hereof, in order to enforce payment of this Note by them, to first
        institute suit or exhaust its remedies against Maker or any others liable
        hereunder, or to enforce its rights against any security hereunder, and (iv)
        consent to any extensions or postponements of time of payment of this Note
        or
        any other indulgences with respect hereto without notice thereof to any of
        them.

      

      Maker
        and
        Payee hereby agree that this Note is performable in Houston, Harris County,
        Texas. 

      

      This
        Note
        is secured by a Security Agreement (the "Security
        Agreement"),
        executed or to be executed by Maker, as debtor, and Payee, as secured party,
        covering certain collateral more particularly therein.

      (e) The
        Company owns the Collateral free and clear of any lien, security interest,

          -7-

          
            

          

        

        
          
          

        

      

      (f) This
        Agreement creates a valid and perfected first priority security interest
        in the

        or desirable to perfect and protect such security interest have been duly
        taken.

      

      (g) No
        authorization, approval or other action by, and no notice to or filing with,
        any
        governmental authority or regulatory body is required either (i) for
        the

        and

        Company is “located” (as such term is defined and used in the UCC) in its
        jurisdiction of incorporation specified in the Perfection
        Certificate.

      

      (i) The

        business in all jurisdictions in which the nature of the business conducted
        by
        the Company makes such qualification necessary and where failure so to qualify
        would not have a material adverse effect on the Company’s financial condition,
        operations, prospects or business, or the Company’s ability to perform all the
        Company’s obligations under this Security Agreement and the other Financing
        Documents to which the Company is a party.

      

      (j) The
        Company is not in violation of any applicable law, which violations,
        individually or in the aggregate, would affect the Company’s performance of any
        obligation under this Security Agreement or the other Financing Documents
        to
        which the Company is a party; there is no litigation before any court or
        governmental authority now pending or (to the Company’s knowledge after
        reasonable inquiry) threatened against the Company which, if adversely
        determined, could reasonably be expected to have a material adverse effect
        on
        the Company’s financial condition, operations, prospects or business as a whole,
        or ability to perform all the Company’s obligations under this Security
        Agreement and the other Financing Documents to which the Company is a
        party.

      

      (k) The
        Company is the holder of all governmental approvals, permits and licenses
        required to permit the Company to enter into and perform the Company’s

        to
        which the Company is a party.

      

      (l) None
        of
        the execution and delivery of this Security Agreement, the consummation of
        the
        transactions contemplated in this Security Agreement or the other Financing
        Documents to which the Company is a party, or compliance with the terms and
        provisions of this Security Agreement or the other Financing Documents to
        which
        the Company is a party will conflict with or result in a breach of, or require
        any consent under, the Company’s charter or bylaws, or any applicable law, or
        any agreement or instrument to which the Company is a party or by which the
        Company is bound or to which the Company or any of the Company’s respective
        assets are subject, or constitute a default under any such agreement or
        instrument.

      

      (m) The
        Company has all necessary power and authority to execute, deliver and perform
        the Company’s respective obligations under this Security Agreement and the other
        Financing Documents to which the Company is a party; the Company’s execution,
        delivery and performance of this Security Agreement and the other Financing
        Documents to which the Company is a party has been duly authorized by all
        necessary action on the Company’s part; and this Security Agreement and the
        other Financing Documents to which the Company is a party have been duly
        and
        validly executed and delivered by the Company and constitutes the Company’s
        legal, valid and binding obligation, enforceable in accordance with its and
        their terms, except as the enforceability thereof may be limited by bankruptcy,
        insolvency, reorganization or moratorium or other similar laws relating to
        the
        enforcement of creditors' rights generally and by general equitable
        principles.

      4. Places
        of Business.
        The
        Company will notify Factor promptly of the addition or discontinuance of

        securing an obligation against the Collateral, will defend the Collateral

        Factor, and will not create, incur, assume, or suffer to exist now or at
        any
        time throughout the duration of the term of this Security Agreement, any
        lien,
        security interest or other encumbrances against the Collateral, whether now
        owned or hereafter acquired, except for liens in favor of Factor, any liens
        listed herein, and any other liens allowed in writing by the
        Factor.

      7. Additional
        Provisions Concerning the Collateral.

       

      (a) The
        Company authorizes Factor to file, without the signature of the Company,
        where
        permitted by law, one or more financing or continuation statements, and
        amendments thereto, relating to the Collateral, all in the discretion of
        Factor.

       

      (b) The
        Company hereby irrevocably appoints Factor as its attorney-in-fact (which
        power
        of attorney is coupled with an interest) and proxy, with full authority in

        (iii) to receive, endorse, and collect any cash, checks, drafts or other

        Company hereby ratifies and approves in advance all acts of said attorney;
        and
        so long as the attorney acts in good faith and without gross negligence it
        shall

      (c) If
        the
        Company fails to perform any agreement contained herein, Factor may itself

        by the
        Company and shall be fully secured hereby.

       

      (d) The
        powers conferred on Factor hereunder are solely to protect its interest in
        the
        Collateral and shall not impose any duty upon Factor to exercise any such

        the
        accounting for moneys actually received by it hereunder, Factor shall have
        no

        or
        duties of the Company thereunder or to take any action to collect or enforce
        any
        claim for payment assigned hereunder.

       

      (f) The
        Company will maintain (A) the location of its place of business and

                  this
                  Security Agreement or any other Financing Document shall prove

                  been incorrect, false, incomplete or
                  misleading;

              

      

       

      
        	 	
                (b)

              	
                the

                  agreement contained in this Security Agreement or any other Financing

                  days
                  after written notice thereof shall have been given by

      11. Remedies.
        (a)
        Upon the occurrence of a Default and at any time or times during the continuance
        thereof, unless such Default shall have been cured within the applicable
        time
        period, if any, or waived in writing by Factor, and subject to the provisions
        of
        applicable law, Factor may exercise any one or more of the following
        remedies:

       

      
        	 	
                (i)

              	
                Factor
                  shall have full power and authority to sell or otherwise dispose
                  of the
                  Collateral or any part thereof. Any such sale or other disposition,
                  subject to the provisions of applicable law, may be by public or
                  private
                  proceedings and may be made by one or more contracts, as a unit
                  or in
                  parcels, at such time and place, by such method, in such manner
                  and on
                  such terms as Factor may determine. Except as required by law,
                  such sale
                  or other disposition and such notice will be deemed to have been
                  sufficiently given if such notice is hand-delivered or mailed postage
                  prepaid, at least ten (10) days before the time of such sale or
                  other
                  disposition, to the Company at its address as specified in the
                  Agreement.
                  To the extent permitted by law, Factor may buy any or all of the
                  Collateral upon any sale thereof. To the extent permitted by law,
                  upon any
                  such sale or sales, the Collateral so purchased shall be held by
                  the
                  purchaser absolutely free from any claims or rights of whatsoever
                  kind or
                  nature, including any equity of redemption and any similar rights
                  being
                  hereby expressly waived and released by the Company. In connection
                  with
                  any such sale, Factor shall be permitted to limit its warranties
                  to the
                  maximum extent provided in the UCC. After deducting all reasonable
                  costs
                  and expenses of collection, custody, sale or other disposition
                  or delivery
                  (including legal costs and reasonable attorneys' discounts) and
                  all other
                  charges due against the Collateral, the residue of the proceeds
                  of any
                  such sale or other disposition shall be applied to the payment
                  of the
                  Obligations, except as otherwise provided by law or directed by
                  any court
                  of competent jurisdiction thereof, and any surplus shall be returned
                  to
                  the Company, except as otherwise provided by law or any such court.
                  The
                  Company shall be liable for any deficiency in payment of the Obligations,
                  including all reasonable costs and expenses of collection, custody,
                  sale
                  or other disposition or delivery and all other charges due against
                  the
                  Collateral, as herein enumerated.

              

      

       

      
        
          
          

        

        
          -11-

          
            

          

        

        
          
          

        

      

      
        	 	
                (ii)

              	
                Factor
                  may notify an account debtor to make payment to Factor whether
                  the Company
                  or Factor was previously making collections on any of the accounts
                  receivable; and Factor may also take control of any proceeds from
                  any
                  Collateral.

              

      

       

      
        	 	
                (iii)

              	
                At
                  any other time, with or without notice, Factor is authorized to
                  offset and
                  charge against any other credits and obligations ever owed by Factor
                  to
                  the Company, any amount for which the Company may become obligated
                  to
                  Factor at any time, whether under the Financing Documents or otherwise.
                  The obligation secured by the Security Interest granted and by
                  Factor's
                  right of offset includes all obligations of any kind or type now
                  or
                  hereafter arising, owed by the Company to Factor, whether liquidated
                  or
                  unliquidated, direct or indirect, contingent or
                  not.

              

      

       

      
        	 	
                (iv)

              	
                Factor
                  may commence proceedings in any court of competent jurisdiction
                  for the
                  appointment of a receiver (which term shall include a receiver-manager)
                  of
                  the Collateral or of any part thereof or may by instrument in writing
                  appoint any person to be a receiver of the Collateral or any part
                  thereof
                  and may remove any receiver so appointed by Factor and appoint
                  another in
                  his stead; and an such receiver appointed by instrument in writing
                  shall
                  have power (a) to take possession of the Collateral or any part
                  thereof,
                  (b) to carry on the business of the Company, (c) to borrow money
                  on the
                  security of the Collateral in priority to this Security Agreement
                  to the
                  extent required for the maintenance, preservation or protection
                  of the
                  Collateral or any part thereof or for the carrying on of the business
                  of
                  the Company, and (d) to sell lease or otherwise dispose of the
                  whole or
                  any part of the Collateral at public auction, by public tender
                  or by
                  private sale, either for cash or upon credit, at such time and
                  upon such
                  terms and conditions as the receiver may determine; provided that
                  any such
                  receiver shall be deemed the agent of the Company and Factor shall
                  not be
                  in any way responsible for any misconduct or negligence of any
                  such
                  receiver.

              

      

       

      
        	(v)  	
                Factor
                  shall have all other rights and remedies of a secured party provided
                  under
                  the UCC.

              

      

       

      
        
          	(vi)  	
                  Factor
                    shall have the right to convert any outstanding balance into
                    free trading
                    shares of ATSI Communications common stock at a conversion price
                    of $.01
                    per share.

                

        

        
          	 	 

        

        
          	
                       
                     (vii)

                	
                  
                    Factor
                      shall have all other rights and remedies allowed at law and/or
                      in
                      equity.

                  

                

        

      

       

      b. It
        is
        provided, however, that notwithstanding Factor's efforts in collection on
        the
        Collateral, the Company shall be liable and responsible for any
        deficiency.

       

      12. Limitation
        on Duty of Factor in Respect of Collateral.
        The
        powers conferred on Factor under this Security Agreement are solely to protect
        Factor’s interest in the Collateral and shall not impose any duty upon Factor to
        exercise any such powers. Except for reasonable care in the custody of any
        Collateral in Factor’s possession and the accounting for moneys actually
        received by Factor under this Security Agreement, Factor shall have no duty
        as
        to any Collateral or as to the taking of any necessary steps to preserve
        rights
        against prior parties or any other rights pertaining to any Collateral. Factor
        shall be deemed to have exercised reasonable care in the custody and
        preservation of the Collateral in Factor’s possession if the Collateral is
        accorded treatment substantially equal to that which Factor accords Factor’s own
        property, it being understood that Factor shall not be liable or responsible
        for
        any loss or damage to any of the Collateral, or for any diminution in the
        value
        thereof, by reason of the act or omission of any warehouseman, carrier,
        forwarding agency, consignee or other bailee selected by Factor in good faith.
        Except as otherwise expressly provided in this Section
        12,
        the
        Company has the risk of loss of the Collateral. Further, Factor has no duty
        to
        collect any income accruing on the Collateral or to preserve any rights relating
        to the Collateral. Factor shall have no obligation to clean up or otherwise
        prepare the Collateral for sale.

      

      
        
          
          

        

        
          -12-

          
            

          

        

        
          
          

        

      

      13. Concerning
        Factor.
        In
        furtherance and not in derogation of the rights, privileges and immunities
        of
        Factor set forth in the Factoring Agreement:

      

      (a) Factor
        is
        authorized to take all such action as is provided to be taken by Factor under
        this Security Agreement and all other action reasonably incidental thereto.
        As
        to any matters not expressly provided for in this Security Agreement (including
        the timing and methods of realization upon the Collateral), Factor shall
        act or
        refrain from acting in Factor’s discretion.

      

      (b) Factor
        shall not be responsible for the existence, genuineness or value of any of
        the
        Collateral or for the validity, perfection, priority or enforceability of
        the
        Security Interests in any of the Collateral, whether impaired by operation
        of
        law or by reason of any action or omission to act on Factor’s part under this
        Security Agreement. Factor shall have no duty to ascertain or inquire as
        to the
        performance or observance of any of the terms of this Security Agreement
        by the
        Company.

      

      14. Payment
        of Taxes, Charges, Etc.
        Factor,
        at its option, after notice to the Company, may discharge any taxes, charges,
        assessments, security interest, liens or other encumbrances upon the Collateral
        or otherwise protect the value thereof. All such expenditures incurred by
        Factor
        shall become payable by the Company to Factor upon demand, shall bear interest
        at the highest legal rate from the date incurred to the date of payment,
        and
        shall be secured by the Collateral.

       

      15. Waivers.
        To the
        extent permitted by law, the Company hereby waives demand for payment, notice
        of
        dishonor or protest and all other notices of any kind in connection with
        the
        Secured Liabilities except notices required hereby, by law or by any other
        agreement between the Company and Factor. Factor may release, supersede,
        exchange or modify any Collateral or security which it may from time to time
        hold and may release, surrender or modify the liability of any third party
        without giving notice hereunder to the Company. Such modifications, changes,
        renewals, releases or other actions shall in no way affect the Company's
        obligations hereunder.

       

      16. Transfer
        Expenses, Etc.
        The
        Company will pay, indemnify and hold Factor harmless from and against all
        costs
        and expenses (including taxes, if any) arising out of or incurred in connection
        with any transfer of Collateral into or out of the name of Factor and all
        reasonable costs and expenses, including reasonable legal discounts, of Factor
        arising out of or incurred in connection with this Security
        Agreement.

       

      17. Termination.
        This
        Security Interest shall terminate upon the latter of (i) the expiration,
        cancellation or other termination of all duties of the Company under both
        the
        Factoring Agreement and the Note; or (ii) ninety days following the full
        payment, satisfaction, or discharge of all Secured Liabilities. Upon such
        termination, the Factor will deliver to the Company appropriate UCC termination
        statements with respect to Collateral so released from the Security Interest
        for
        filing with each filing officer with which UCC financing statements have
        been
        filed by Factor to perfect the Security Interest in such
        Collateral.

       

      
        
          
          

        

        
          -13-

          
            

          

        

        
          
          

        

      

      18. Successors
        and Assigns.
        This
        Agreement shall be binding upon and inure to the benefit of the Company and
        Factor and their respective successors and assigns.

       

      19. Severability
        of Provisions.
        Any
        provision of any Financing Document which is prohibited or unenforceable
        in any
        jurisdiction shall, as to such jurisdiction, be ineffective to the extent
        of
        such prohibition or unenforceability without invalidating the remaining
        provisions of such Financing Document or affecting the validity or
        enforceability without invalidating the remaining provisions of such Financing
        Document or affecting the validity or enforceability of such provision in
        any
        other jurisdiction.

       

      20. Submission
        to Jurisdiction.
        (a)
        ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS SECURITY AGREEMENT AND
        THE
        OTHER FINANCING DOCUMENTS TO WHICH THE COMPANY IS A PARTY MAY BE BROUGHT
        IN THE
        COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES LOCATED IN HARRIS COUNTY,
        TEXAS AND, BY EXECUTION AND DELIVERY OF THIS SECURITY AGREEMENT, THE COMPANY
        HEREBY IRREVOCABLY ACCEPTS FOR ITSELF AND IN RESPECT OF THE COMPANY’S PROPERTY,
        UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS WITH RESPECT TO
        ANY
        SUCH ACTION OR PROCEEDING. THE COMPANY FURTHER IRREVOCABLY CONSENTS TO THE
        SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION
        OR
        PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL,
        POSTAGE PREPAID, TO THE COMPANY PURSUANT TO SECTION
        22,
        SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING
        IN
        THIS SECURITY AGREEMENT SHALL AFFECT THE RIGHT OF FACTOR TO SERVE PROCESS
        IN ANY
        OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
        PROCEED AGAINST THE COMPANY IN ANY OTHER JURISDICTION.

      

      (b) THE
