         This agreement is made this 20th day of May, 1999 between Tech Squared,

of the covenants set forth herein, the parties agree as follows:

1. Seller agrees to sell, transfer and convey to Buyer, and Buyer agrees to

2. The price to be paid to Seller by Buyer for the shares of Tabor is $50,000,
payable as follows: Buyer will, upon execution of this Agreement, transfer to
Seller 16,000 shares of the capital stock of LSI Communications, Inc. (LSI), a
Nevada corporation ("LSI Shares"). Buyer agrees that unless Seller is able,
within 90 days from acquiring the shares of LSI, to sell the shares for at least
$50,000, Buyer will pay Seller the difference between the amount Seller is able
to obtain from the sale of the LSI Shares and $50,000 ("shortfall"). Seller may
commence selling all or a portion of the LSI Shares at any time after the
closing of this agreement. Any shortfall will be paid by Buyer in a single cash
payment, due within 15 days after being notified by Seller of a shortfall in the
sale price of the shares. Seller can make such notice upon the earlier of the
time all the LSI Shares have been sold or within 90 days from acquiring the LSI
Shares. By his signature of this Agreement as Guarantor, Bill Campbell, one of
the shareholders of Buyer, guarantees Buyer's obligation stated in this
paragraph.

the LSI Shares in LSI's books and records, that the LSI shares (I) are validly
authorized, validly issued, fully paid and nonassessable, (ii) have not been
issued and are not owned or held in violation of any preemptive right of stock
holders, (iii) are free and clear of all liens, security interests, pledges,
charges, encumbrances, stock holders agreements and voting trusts, (iv) are not
restricted securities as defined in Rule 144 adopted under the Securities Act of
1933 and will not be restricted upon closing, and (v) are freely transferable
upon closing.

Upon transfer to Seller of the LSI shares, Seller will transfer the Tabor shares
to Buyer.

3. The parties recognize and agree that the outstanding capital shares of Tabor,
hereby transferred from Seller to Buyer, represent ownership of all of the

liabilities of Tabor. Seller warrants only that it has the full right to sell
and transfer the shares of Tabor held in its name. Buyer expressly assumes

against any claims hereafter asserted by third parties arising in any manner
out of actions, failures to act, or property ownership of Tabor, before or
after this sale and purchase.
