Acquisition or Disposition of Assets On September 3, 1999, SI Diamond Technology, Inc. ("SIDT") and SIDT, Inc., its wholly owned indirect subsidiary closed an asset purchase with Sign Builders of America, Inc. ("SBOA") and Sign Builders, Inc., a wholly owned subsidiary of SBOA (collectively these two companies are referred to herein as the "Seller"), and Lance Adams ("Adams") who owned 100% of the common stock of SBOA, in which SIDT, Inc. purchased all of the assets of Seller. At the Closing: (1) SIDT, Inc. paid $150,000 in cash to Seller and $300,000 in cash to Adams (2) SIDT, Inc. executed a promissory note ("Note"), guaranteed by SIDT, in the amount of $450,000 payable to SBOA. Such Note is convertible, at the sole option of SBOA, into an equivalent value of shares of SIDT common stock as follows: (a) The Note will bear interest at the rate of 6% per annum and shall be due and payable in two equal installments, the first due 6 months from the Closing Date and the second due one (1) year from the Closing Date. (b) Payment of the Note is secured by the Seller retaining a security interest in the assets transferred to SIDT, Inc. (c) $225,000 of the principal amount of the Note, plus accrued and unpaid interest, is convertible into SIDT Common Stock 6 months from the Closing Date. The remaining principal amount of $225,000, plus accrued and unpaid interest is convertible one year from the Closing Date. The conversion rate for converting the Note amounts into shares of SIDT Common Stock is equal to $2.127. If SBOA elects to convert the Note into shares of SIDT Common Stock (whether in whole or part), the number of shares of SIDT Common Stock to be issued shall be determined by dividing the amount of the Note being converted (including accrued interest) by the conversion rate of $2.127. SBOA, at its option may make an election individually on each payment as to whether to receive cash or SIDT Common Stock. (d) However, the Purchase Price is based on the requirement that the Gross Sales of Seller and SIDT for the 1999 calendar year be at least equal to $3,000,000. To the extent that such Gross Sales fall below $3,000,000, the principal balance of the Note shall be reduced proportionately. The Note shall be reduced in the amount of $1.00 for each $2.00 of sales that the actual Gross Sales fall below $3,000,000. (3) SIDT issued 329,101 shares of SIDT Common Stock to SBOA and 94,030 shares to Adams. Adams owns 100% of the common stock of SBOA. SIDT agreed to register these shares of SIDT Common Stock as soon as administratively possible. If SIDT is unable to accomplish this registration within 6 months of the Closing Date, SIDT will issue Seller and Adams an additional number of shares of SIDT Common Stock equal to 20% of the number of shares of SIDT Common Stock issued to Seller and Adams at the Closing Date. SIDT agreed to keep this registration effective for a period of 1 year. The assets acquired in this transaction are for use in connection with the building of electronic billboards and related products. SIDT intends to continue to use and devote these assets to such business. SIDT used working capital funds to pay the cash portion of the purchase price identified above. After the closing, Mr. Adams will become employed by SIDT as an officer of Electronic Billboard Technology, Inc. and SIDT, Inc., its wholly-owned subsidiaries. 3 Item 7.
