authorized to transact business in Texas.

A.       KBK has contemporaneously herewith entered into that certain Account
         Transfer and Purchase Agreement of even date herewith (such agreement,
         and all amendments and modifications thereof, collectively, the
         "Purchase Agreement"), to which reference is made for all purposes,
         with AESP, Inc. (referred to herein as the "Seller"), pursuant to which
         KBK has purchased or will purchase all right, title and interest in
         certain accounts receivable of the Seller (the "Accounts"), on those
         terms and conditions set forth in the Purchase Agreement.

B.       KBK is willing to enter into the Purchase Agreement only if the
         Guarantors execute and deliver this Guaranty to KBK.

NOW, THEREFORE, in consideration of the aforesaid premises and other good and
valuable consideration, and for the purpose of inducing KBK to enter into the
Purchase Agreement and to purchase accounts receivable from the Seller pursuant
to the terms thereof, the sufficiency of which is hereby acknowledged, the
Guarantors hereby covenant and agree as follows:

1.       The Guarantors hereby unconditionally and irrevocably guarantee the
         payment in full of any losses incurred by KBK under the Purchase
         Agreement (collectively the "Obligations") to the extent that such
         losses are related to or attributable to any of the following limited
         circumstances only:

         (a)      In the event any of the representations and warranties set
                  forth in the first sentence of Section 9 of the Purchase
                  Agreement was not true when made or ceases to be true for any
                  reason.

         (b)      In the event that the Seller, the Guarantors, or any other
                  person, without receiving prior written consent from KBK,
                  shall cash, deposit, or retain, any checks, drafts, monies or
                  proceeds of the Accounts purchased by KBK, and the Seller
                  shall fail to immediately tender the entire amount of the same
                  to KBK.

         Notwithstanding any provision to the contrary contained herein, the
         Guarantors shall have no liability hereunder with respect to any
         account which is not paid as a result of the financial inability of the
         subject account debtor to pay such account.

2.       KBK shall not be required, as a condition precedent to making a demand
         upon the Guarantors or to bringing an action against the Guarantors
         under this Guaranty, to make demand upon, or to institute any action or
         proceeding, at law or in equity against the Seller or anyone else, or
         to exhaust its remedies against the Seller, or anyone else, or against
         any collateral security. All remedies afforded to KBK by reason of this
         Guaranty are separate and cumulative remedies and it is agreed that not
         one of such remedies, whether exercised by KBK or not, shall be deemed
         to be exclusive of any of the other remedies available to KBK and shall
         not limit or prejudice any other remedy which KBK may have against any
         party, including the Guarantors.

3.       The Guarantors shall remain liable on this Guaranty notwithstanding any
         change or changes in the terms, covenants or conditions of the Purchase
         Agreement, or any amendment thereto, hereafter made or granted, or any
         delay on the part of KBK in exercising its rights hereunder or
         thereunder, it being the intention hereof that the Guarantors shall
         remain liable as principal until the full amount of the Obligations
         guaranteed hereby, with interest and any sums which may be due thereon,
         shall have been fully paid, notwithstanding any act or omission which
         might otherwise operate as a legal or equitable discharge of the
         Guarantors.

4.       The Guarantors hereby waive (a) notice of acceptance of this Guaranty;
         (b) presentment and demand for payment of the Obligations or any
         portion thereof; (c) protest and notice of dishonor or default to the
         Guarantors or to any other person or party with respect to the

         Guarantors might otherwise be entitled; (e) any demand for payment or
         performance of this Guaranty; and (f) all Guaranty and suretyship

         time such financial statements and other financial information of
         Guarantors as KBK may require, in form and detail satisfactory to KBK
         (including, without limitation, annual financial statements within 45
         days after the end of each calendar year).

6.       This Guaranty shall inure to the benefit of, and may be enforced by
         KBK, and its respective successors and assigns, and shall be binding
         upon and enforceable against the Guarantors and his respective heirs,
