                                 ---------------

$1,000,000.00                                                    August 15, 2006

         For value received, Airgate Technologies, a Texas Corporation
("AIRGATE"), and The X-Change Corporation, a Nevada corporation ("X-CHANGE", and
collectively with Airgate, "BORROWERS"), jointly and severally promise to pay to
the order of Melissa CR 364 Ltd., a Texas limited Partnership ("LENDER") at 416
CR 364 Melissa, TX 75454, or at such other address as Lender shall from time to
time specify in writing, the principal sum of One Million AND NO/100 DOLLARS
($1,000,000.00) (the "MAXIMUM AMOUNT"), or so much thereof as may be advanced by
Lender pursuant to the terms hereunder, in legal and lawful money of the United
States of America, with interest on the outstanding principal from the date
advanced until paid at the rate set out below. Interest shall be computed on a
per annum basis of a year of 360 days, and for the actual number of days
elapsed. All payments to Lender under this Note shall be without offset.

         1. LOAN; ADVANCES.

                  (a) LOAN. Subject to Borrowers' compliance with the terms of
         this Note, Lender agrees to make loan advances (each such advance, a
         "LOAN" and collectively, the "LOANS") to Airgate or on behalf of
         Airgate from time to time in immediately available funds, in the amount
         determined pursuant to Section 1(b), until a Maximum amount of One
         Million ($1,000,000.00) Dollars has been reached. Notwithstanding
         anything contained herein to the contrary, Lender shall not be
         obligated to make a Loan requested under Section 1(b) if the
         outstanding principal amount of all Loans made by Lender, after giving
         effect to the proposed Loan requested by Borrower, shall exceed the
         Maximum Amount. At the date of the execution of this promissory note
         the initial advance covering all previous notes due from borrower is
         acknowledged to be Seven Hundred Fifty Eight Thousand and Eighty Five
         and no/100 dollars ($758,085.00). This amount includes any and all
         interest due on the previous notes which was due through August 1,
         2006.

                  (b) REQUEST FOR LOAN. Airgate shall provide X-Change and
         Lender with a request for each draw. Subject to Borrowers compliance
         with the terms of this Note, Lender agrees to make a Loan equal to the
         amount of each draw by wire transfer or check in immediately available
         funds no later than five (5) days following Lender's receipt of such
         request.

                                       1


                  (c) RECORDATION OF AMOUNT OF ADVANCES. In the absence of
         manifest error, the books and records of Lender shall be conclusive and
         binding upon Borrowers as to the principal balance of the Loan
         outstanding at any time and the amount of accrued interest thereon.

         2. INTEREST RATE. Interest on the outstanding and unpaid principal
balance hereof shall be computed at a per annum rate equal to the lesser of (a)
10.00%, or (b) the Maximum Legal Rate (as defined below). In no event will the
interest rate stated herein be an amount less than the Applicable Federal Rate
(the "AFR") proscribed by the Internal Revenue Service for this Note to have
adequate stated interest for debt instruments of the same nature and term as
this Note. Notwithstanding anything herein to the contrary, should the interest
rate stated herein be insufficient to meet the required AFR, then such interest
rate will be adjusted accordingly retroactive to the date of this Note. If this
Note has already been repaid in full, then an additional interest amount will be
computed in accordance with the immediately preceding sentence and immediately
paid by Borrowers, along with interest on the amount of such additional interest
through the date of payment at a rate per annum equal to the then existing
interest rate on this Note.

         3. PAYMENT OF LOAN AND INTEREST. Borrowers hereby unconditionally
promise to pay to Lender the then unpaid principal amount, together with all
unpaid accrued interest, of the Loans as follows:

                  (a) This Note is due and payable as follows, to-wit: Interest
         only for a period of 24 months when the entire balance shall be due and
         payable. The first such payment due and payable on the 1st day of
         November, 2006, and a like installment shall be due and payable on the
         same day of each succeeding quarter thereafter until the total
         principal of $ any outstanding amount up to the maximum loan amount is
         paid in full. If each payment is not paid on time, the remaining
         balance will be subject to the maximum amount of interest permitted by
         the Laws of the State of Texas.

                  (b) To induce the lender to enter into this loan, the
         borrower's have pledged 100% of the outstanding stock in AirGATE
         Technologies Inc, a Texas Corporation (AGTI), doing business at 710
         Century Blvd, Allen, TX 75013. Lender agrees that the AGTI stock will
         be returned The X-Change Corporation when this note is paid in full.

                  (c) At the sole discretion of lender the principal amount and
         any accrued interest that is due and payable on this note may be
         converted into restricted common stock of The X-Change Corporation, at
         any time during the term of this note. The conversion rate shall be at
         50% of the closing price of The X-Change Corporation common stock on
         August 11, 2006. Said closing price was $1.65.

         4. ADJUSTMENT UPON REORGANIZATION OF COMPANY. In case of any capital
reorganization, conversion, reclassification or recapitalization of the Common
Stock or in case X-Change consolidates or merges with or into, or transfers or
leases all or substantially all its assets to, any other person or entity, upon
consummation of any such transaction the payment obligations of Borrowers
contained in SECTION 3 shall become payable in the kind and amount of
securities, cash or other assets that the holder of Shares receives as
consideration for such transaction, or as a result of its ownership of the
Shares in connection with such transaction.

                                       2


         5. OPTIONAL PREPAYMENT. Borrowers reserve the right to prepay, prior to
maturity, all or any part of the principal of this Note without penalty. Any
prepayments shall be applied first to accrued interest and then to principal.

         remedied within ten (10) days after the occurrence thereof;

                  (b) Any representation or warranty made by any Borrower in
         this Note or in any certificate or document furnished in connection

                  (c) Any Borrower shall fail or neglect to perform, keep or

         be remedied within thirty (30) days after such Borrower learns of such
         failure to comply, whether by its own discovery or through notice from
         Lender (other than a breach caused solely by a violation by Lender of
         its obligations under this Note); or

                                       4

         rearrangement, receivership, insolvency, reorganization, or similar
         debtor relief laws from time to time in effect affecting the rights of
         creditors generally), or (iv) be made the subject of any proceeding
         provided for by any Debtor Relief Law that could suspend or otherwise
         affect any of the rights of the holder hereof.

         10. REMEDIES UPON AN EVENT OF DEFAULT. Upon the occurrence of an Event
of Default, the holder of this Note may (a) offset against this Note any sum or
sums owed by the holder hereof to any Borrower, and (b) proceed to protect and

applicable law, determination of the legal maximum amount of interest shall at
all times be made by amortizing, prorating, allocating and spreading in equal
parts during the period of the full stated term of the loan and indebtedness,
all interest at any time contracted for, charged or received from any Borrower
hereof in connection with the loan and indebtedness evidenced hereby, so that
the actual rate of interest on account of such indebtedness is uniform
throughout the term hereof.

jurisdiction other than the State of Texas. Any legal action or proceeding with
respect to this Note may be brought in any Texas state or federal court sitting
