           Case No. 98-WY-1 22-CB:  SETTLEMENT AGREEMENT
                      date: September 2, 1999

     All defendants sign the following agreement. Norman Rounds signs
on behalf of all plaintiffs, and Mr. Rounds represents that he has
complete authority from all plaintiffs to settle all claims on behalf
of plaintiffs.

     In exchange for a dismissal and complete releases from plaintiffs
and Norman Rounds, defendants agree as follows:

     1. To pay $60,000 in cash on the date of closing, which is
scheduled for no later than October 4, 1999.

     2. To cancel a note of $50,000 which is owed by Norman Rounds to
Crosby Enterprises.

     3. To pay to plaintiffs on September 7, 1999, the number of shares
of Metalline stock, based upon Schwab closing price as of September 2,
1999, which equals $80,000. This payment shall be made by delivering
the shares to Idaho Stock Transfer to hold these shares in escrow to be
released to plaintiffs and to Mr. Rounds, as Mr. Rounds designates, in
the amount of 5,000 shares every thirty days, beginning with the first
5,000 shares to be delivered September 7, 1999. Mr. Rounds and/or
plaintiffs will be limited in their ability to sell the shares of stock
as follows:

          (a) Plaintiffs and Mr. Rounds shall be able to sell no more
     than 5000 shares of stock total per month so long as the stock is
     trading at less than $4.50 per share.

          (b) Whenever the stock closes at over $4.50 per share Schwab
     NAV closing price for five consecutive trading days, the transfer
     agent will be authorized to release to plaintiff all remaining
     shares.

     This Agreement contains all essential terms of the agreement which
has been reached between the undersigned parties. All of the
undersigned parties agree that these terms constitute the total
agreement, and agree to be bound by these terms.
