WE ARE THE HOLDER OF RECORD OF COMMON SHARES HELD BY US FOR YOUR ACCOUNT. A TENDER OF SUCH COMMON SHARES CAN BE MADE ONLY BY US AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER COMMON SHARES HELD BY US FOR YOUR ACCOUNT. Accordingly, we request instructions as to whether you wish to have us tender on your behalf any or all Common Shares held by us for your account pursuant to the terms and conditions set forth in the Offer. Please note the following: 1. The tender price is $1.00 per Common Share, net to you in cash, without interest thereon, upon the terms and subject to the conditions set forth in the Offer. 2. The Offer is being made for all outstanding Common Shares not already owned by Donald C. Weymer, the Purchaser's founder, Chief Executive Officer, President, a Director and 98% shareholder. 3. The Board of Directors of the Company has determined that, based on the Company's current financial condition, its inability to obtain financing for its operations, recent bid prices for the Common Shares on the OTC Bulletin Board and the Company's current book value, the Offer is in the best interests of the Company and its stockholders and has voted to recommend to the Company stockholders acceptance of the Offer. The Board of Directors of the Company recommends that the Company's stockholders tender their Common Shares pursuant to the Offer. 4. The Offer is subject to certain customary closing conditions set forth in the Offer to Purchase. See Section 10, "Conditions of the Offer," of the Offer to Purchase. 5. Any stock transfer taxes applicable to the sale of Common Shares to the Purchaser pursuant to the Offer will be paid by the Purchaser, except as otherwise provided in Instruction 6 of the Letter of Transmittal. 6. The Offer and withdrawal rights will expire at 5:00 P.M., Eastern Time, on Tuesday, May 23, 2000, unless the Offer is extended. 7. Payment for Common Shares purchased pursuant to the Offer will in all cases be made only after timely receipt by the Depositary of (a) Share Certificates or timely confirmation of the book-entry transfer of such Common Shares into the account maintained by the Depositary at The Depository Trust Company, pursuant to the procedures set forth in Section 3, "Procedures for Accepting the Offer and Tendering Shares," of the Offer to Purchase, (b) the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, with any required signature guarantees or an Agent's Message (as defined in the Offer to Purchase), in connection with a book-entry delivery, and (c) any other documents required by the Letter of Transmittal.

The Purchaser is not aware of any state where the making of the Offer is prohibited by administrative or judicial action pursuant to any valid state statute. If the Purchaser becomes aware of any valid state statute prohibiting the making of the Offer or the acceptance of the Common Shares pursuant thereto, the Purchaser will make a good faith effort to comply with such statute or seek to have such statute declared inapplicable to the Offer. If, after such good faith effort, the Purchaser cannot comply with such state statute, the Offer will not be made to (nor will tenders be accepted from or on behalf of) holders of Common Shares in such state.
