FOR VALUE RECEIVED the undersigned (hereinafter referred to as "Guarantors" whether one or more)
                    jointly and severally guarantee unconditionally the payment of and promise to pay the Issuing Bank
                    of the Card and Credit Devices issue pursuant hereto (hereinafter referred to as "Bank") any and all
                    indebtedness and obligations, whether direct or indirect, absolute or contingent, primary or
                    secondary, or joint or several and all renewals and extensions thereof, for which Borrower is now,
                    or hereafter may become libel or indebted to Bank, whether such liability or indebtedness be in
                    contract or tort; provided, however, that Guarantors shall not be required to pay Bank under this
                    Guaranty Agreement an aggregate sum of more than the total interest and attorney's fees which may be
                    or become owing by Borrower to Bank, plus the sum of the total outstanding balance of all Cards
                    issued by Bank for the account of Borrower.
                Notwithstanding any other provision of this guaranty or the guaranteed indebtedness, Bank and
                    Guarantors agree that Guarantors shall never be required or obligated under the terms hereof or
                    under the terms of any note, instrument or other agreement evidencing any of the guaranteed
                    indebtedness, to pay interest in excess of the maximum interest rate as may be authorized by law for
                    written contracts which constitute the guaranteed indebtedness and for the Guarantors. It is the
                    intention of the parties hereto to conform strictly to the applicable laws which limit interest
                    rates, and any of the aforesaid contracts for interest, if and to the extent payable by Guarantors,
                    shall be held to be subject to reduction to the maximum interest rate allowed under said laws.
                Guarantors hereby severally waive notice of acceptance of this guaranty and all other notices in
                    connection herewith or in connection with the indebtedness or obligations guaranteed hereby, and
                    waive diligence, presentment, protest, and suit on the part of Bank in the collection of any
                    indebtedness or obligation hereby guaranteed, and agree that Bank shall not be required to first
                    endeavor to collect from Borrower any indebtedness or obligation hereby guaranteed, or to foreclose,
                    proceed against, or exhaust any collateral or security for any indebtedness or obligation hereby
                    guaranteed, before requiring Guarantors, or any of them, to pay the full amount of the guaranteed
                    obligations. Suit may be brought and maintained against any one or more of the undersigned
                    Guarantors at the election of Bank, without joinder of Borrower or any other Guarantor as parties
                    thereto. If any sum due Bank by Guarantors hereunder is placed in the hands of an attorney for
                    collection, or is collected through probate, bankruptcy, or other court proceeding, that the
                    undersigned Guarantors, jointly and severally, promise to pay Bank on demand any and all attorney's
                    fees and other costs and expenses incurred by Bank.
                This guaranty is continuing and shall continue to apply without regard to the form or amount of
                    indebtedness or obligation guaranteed which Borrower may create, renew, extend, or alter, in whole
                    or in part, without notice to Guarantors. This guaranty also includes, but is not limited to,
                    fraudulent use of the card or unauthorized use of the card as a result of the card being lost or
                    stolen.
                If the status of Borrower changes, this guaranty agreement shall continue and also cover the
                    indebtedness of Borrower under the new status, according to the terms hereof.
                If, for any reason, the guaranteed indebtedness cannot be enforced against Borrower, or any payments
                    thereon must be refunded by Bank to any party for any reason, including bankruptcy, such fact shall
                    not affect the liability of Guarantors hereunder, and Guarantors shall be liable hereunder to the
                    same extent as if the guaranteed indebtedness has been enforceable against Borrower or said payments
                    had not been made to Bank.
                Bank may settle or agree with any of the Guarantors for such sum or sums as it may see fit and
                    release such of the Guarantors from all further liability to Bank for guaranteed indebtedness
                    without impairing the right of Bank to demand and collect the balance of the guaranteed indebtedness
                    from others of the Guarantors not so released.
                Bank may surrender, release, exchange, or alter any collateral or security for any indebtedness or
                    obligation hereby guaranteed without affecting the liability of Guarantors under this guaranty, and
                    this guaranty shall continue effective notwithstanding any legal disability of Borrower.
                In the event of the death of any of the undersigned Guarantors, this guaranty shall bind the
                    decedent, his heirs, executors, and administrators only as to the indebtedness and obligations of
                    Borrower to Bank which are existing at the time notice in writing of such death is received by the
                    Cashier of Bank and as to all renewals and extensions thereof, in whole or in part whenever made,
                    but this guaranty agreement shall continue in full force and effect as to all other of the
                    undersigned Guarantors. No notice shall be deemed received by the Cashier of Bank unless and until
                    the said Cashier has acknowledged receipt thereof in writing.
                Each of the undersigned Guarantors acknowledges that this guaranty is operative and binding as to him
                    without reference to whether it is signed by any other person or persons and without reference to
                    whether it is signed by any other person under any legal disability to sign the same; and that his
                    liability hereunder shall be cumulative and in addition to any other liability or obligation to
                    Bank, whether the same is incurred through the execution of a similar guaranty, through endorsement,
                    or otherwise.
                Guarantors shall furnish to Bank annually (and more frequently if requested by Bank) financial
                    statements, including cash flow and contingent liability information.
                Guarantors jointly and severally represent and warrant to Bank, that the value of the consideration
                    received and to be received by Guarantors as a result of Bank extending credit to Borrower and
                    Guarantors executing and delivering this guaranty agreement is reasonably worth at least as much as
                    the liability and obligation of Guarantors hereunder, and such liability and obligation has
                    benefited or may reasonably be expected to benefit Guarantors directly or indirectly.
                Bank may assign its rights hereunder, in whole or in part, and upon any such assignment all the terms
                    and provisions of this guaranty shall inure to the benefit of such assignee, to the extent so
                    assigned. Any action or inaction by Bank with regard to the guaranteed indebtedness or this guaranty
                    shall not impair or diminish the obligation of Guarantors hereunder. Bank shall not be liable for
                    its failure to use diligence in the collection of the guaranteed indebtedness or in preserving the
                    liability of any person liable thereon. The rights of Bank hereunder shall be cumulative of any and
                    all other rights that Bank may have against Guarantors, or any of them, including but not limited to
                    the right of set-off. The exercise by Bank of any right or remedy hereunder or under any other
                    instrument, at law or in equity, shall not preclude concurrent or subsequent exercise of any other
                    right or remedy.
                This guaranty agreement is performable in Dallas County, Texas, and Guarantors waive the right to be
                    sued elsewhere. This guaranty agreement is not intended and does not replace, cancel or otherwise
                    modify or affect any other guaranty agreement of the Guarantors, or any of them, held by Bank.
                Bank is relying and is entitled to rely upon each and all of the provisions of this agreement; and,
                    accordingly, if any provision or provisions of this instrument shall be held to be invalid or
                    ineffective, then all other provisions shall continue in full force and effect notwithstanding.
                THIS GUARANTY EMBODIES THE FINAL, ENTIRE AGREEMENT OF GUARANTORS AND BANK WITH RESPECT TO GUARANTORS'
                    GUARANTY OF THE GUARANTEED INDEBTEDNESS AND SUPERSEDES ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS,
                    REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF.
                    THIS GUARANTY IS INTENDED BY GUARANTORS AND BANK AS A FINAL AND COMPLETE EXPRESSION OF THE TERMS OF
                    THE GUARANTY, AND NO COURSE OF DEALING BETWEEN GUARANTORS AND BANK, NO COURSE OF PERFORMANCE, NO
                    TRADE PRACTICES, AND NO EVIDENCE OF PRIOR CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR
                    DISCUSSIONS OR OTHER EXTRINSIC EVIDENCE OF ANY NATURE SHALL BE USED TO CONTRADICT, VARY, SUPPLEMENT
                    OR MODIFY ANY TERM OF THIS GUARANTY. THERE ARE NO ORAL AGREEMENTS BETWEEN GUARANTORS AND BANK.
