BILDNER entered into a written Promissory Note in favor of NATIONSBANK, N.A. in the principal sum of TWO MILLION THREE HUNDRED AND TEN THOUSAND DOLLARS ($2,310,000.00). 2. Said Promissory Note was secured by: a.) A Deed of Trust dated August 27, 1998 on real property located at scenic Road 6 SW of Ocean, Carmel, CA 93921 in which NATIONSBANK, N.A. is named as the Beneficiary; and b.) A Pledge Agreement pledging certain shares of Tier Technologies, Inc., a California corporation held in Account No. 209-71082 at NationsBanc Montgomery Securities, LLC, the fair market value of which is required to remain in excess of $2,310,000.00. 3. In consideration of NATIONSBANK, N.A. terminating the Pledge Agreement in number 2(b) above, including its Power of Sale clause, the undersigned hereinafter called "Guarantor", in recognition of the importance of JAMES L. BILDNER as a key employee of the Guarantor, agrees as follows: 1 FOR VALUABLE CONSIDERATION, Guarantor guarantees and promises to pay to NATIONSBANK, N.A. (hereinafter called "Obligee"), on order or demand, in lawful money of the United States, up to and including One Million Dollars ($1,000,000) of the indebtedness of JAMES L. BILDNER and NANCY J. BILDNER (hereinafter called collectively "Borrower"), arising or existing under that certain Promissory Note dated AUGUST 27, 1998, a copy of which is attached hereto, marked Exhibit A and by this reference made a part hereof as though set forth in full and that certain Deed of Trust between JAMES L. BILDNER and Obligee dated AUGUST 27, 1998, (hereinafter collectively called the "Obligation"), a copy of which is attached hereto, marked Exhibit B. Guarantor hereby acknowledges receipt of unsigned copies of the Obligation to Obligee. The word "indebtedness" is used herein in its most comprehensive sense subject to the limitation of liability of ONE MILLION DOLLARS ($1,000,000) and whether recovery upon such indebtedness may be or hereafter become barred by any statute or limitations, or whether such indebtedness may be or hereafter become otherwise unenforceable. The Guarantor shall be entitled to a sixty (60) day period in which to cure any default of Borrower. During any 2 such period, Guarantor shall have an unconditional right to cure any default. Guarantor's payment of any sums in default, without regard to acceleration provisions, shall cure any payment default and allow the note to continue in effect as if no default had occurred. However, Guarantor shall be limited in its ability to cure defaults to a total number of five times over the life of the loan and to no more than two times in any one year. If a payment is made by Guarantor on behalf of Borrower pursuant to the terms of the Promissory Note and said payment is timely, it shall not be considered a default. Additionally, any payments made by Borrower or others on principal due and owing shall reduce the guaranteed amount ($1,000,000) accordingly. Notwithstanding the foregoing, once the principal amount of the obligation is reduced to One Million Three Hundred Ten Thousand Dollars ($1,310,000), this Guaranty shall be automatically revoked. The obligations hereunder are joint and several, and independent of the obligations of Borrower, and a separate action or actions may be brought and prosecuted against Guarantor whether action is brought against Borrower or whether Borrower is joined in any such action or actions; and 3 Guarantor waives the benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof. 1. INDEMNITY. In addition to the payment of expenses pursuant to --------- Paragraph entitled "Expenses" on Page 6, Guarantor agrees to indemnify, defend, exonerate, pay and hold Obligee and the officers, directors, employees and agents of Obligee (the "Indemnitees") harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, causes of action, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including, without limitation, the fees and disbursements of counsel to Obligee and reasonable expert witness fees and disbursements) for such Indemnitees in Connection with any investigative, administrative or judicial proceeding, whether or not such Indemnitee shall be designated a party thereto, that may be imposed on, incurred by or asserted against such Indemnitee, in any manner relating to or arising out of or in connection with this Guaranty (the "Indemnified Liabilities"). Notwithstanding the foregoing, Indemnified Liabilities shall not include liabilities, obligations, losses, damages, penalties, actions, causes of action, judgments, suits, claims, costs, expenses and disbursements to the extent caused by or 4 resulting from the gross negligence or willful misconduct of such Indemnitee. 2. NOTICE. Each Indemnitee will promptly notify Guarantor of each event ------ of which it has knowledge that may give rise to a claim under section 1. 3. DEFENSE OF ACTIONS. If any investigative, judicial or administrative ------------------ proceeding arising in connection with any of the Indemnified Liabilities is brought against any Indemnitee indemnified or intended to be indemnified pursuant to Section 1, Guarantor, to the extent and in the manner directed by the Indemnitee or intended Indemnitee, will resist and defend such action, suit or proceeding or cause the same to be resisted and defended by counsel designated by Indemnitees (which counsel shall be satisfactory to the Guarantor). Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding. To the extent that the undertaking to indemnify, pay and hold harmless set forth in the preceding sentence may be unenforceable because it is violative of any law or public policy, Guarantor shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. 5 4. CONSENTS BY GUARANTOR. Guarantor authorizes Obligee, without notice or --------------------- demand and without affecting its liability hereunder, from time to time to (a) renew, compromise, extend, accelerate (acceleration shall be subject to Guarantor's right to cure a default as set forth on page 3 above) or otherwise change the time for payment of, or otherwise change the terms of the indebtedness or any part thereof, including increase or decrease of the rate of interest therein; (b) take and hold security for the payment of the indebtedness guaranteed, and exchange, enforce, waive and release any such security; (c) apply such security and direct the order or manner of sale thereof as Obligee in its discretion may determine; and (d) release or substitute any one or more of the endorsers or guarantors.

Guarantor waives any right to require Obligee to (a) proceed against Borrower; (b) proceed against or exhaust any security held from Borrower; or (c) pursue any other remedy in Obligee's power whatsoever. Guarantor waives any defense arising by reason of the cessation from any cause whatsoever of the liability of Borrower. Until all indebtedness of Borrower to Obligee shall have been paid in full, Guarantor shall have no right of subrogation, and waives any right to 6 enforce any remedy which Obligee now has or may hereafter have against Borrower, and waives any benefit of, and any right to participate in any security now or hereafter held by Obligee.
