ITEM 2.  Acquisition or Disposition of Assets.
         -------------------------------------

     On September 27, 1996, ERC Industries, Inc., a Delaware corporation (the
"Purchaser"), acquired 100% of the issued and outstanding capital shares of
Seaboard Lloyd Limited (the "Company"), a private company incorporated in
Scotland under the Companies Acts of the United Kingdom.  The Purchaser acquired
the shares of the Company from VSEL Limited, a company incorporated in England
under the Companies Acts of the United Kingdom (the "Seller") in a privately
negotiated transaction.  The acquisition was concluded pursuant to the terms of
a Share Sale and Purchase Agreement dated September 27, 1996 (the "Purchase
Agreement"), by and between the Purchaser and Seller.

     The business of the Company and its subsidiaries has been the manufacture,
supply, repair, maintenance and refurbishment of wellheads, xmas trees, gate
valves, choke valves, clamped pipe connectors, actuators, electric feed through
systems for downhole pumps and subsea ball and check valves, all as used in the
oil and gas industry (the "Business").  The Company's Business is operated in
facilities located in Cumbernauld, Scotland.  The Purchaser plans to continue to
operate the Business of the Company in substantially the same manner as it was
operated prior to the acquisition.

     The Purchaser paid the Seller a purchase price of $1,580,000 cash for the
capital shares of the Company.  The source of the funds for the purchase was
approximately $1,080,000 in cash on hand and $500,000 borrowed under its
existing line of credit with a major bank.  The line of credit is in place until
June 1997, and borrowings under the line of credit bear interest at the bank's
prime rate minus one-half percent.  Current borrowings under the line of credit
are $700,000.00.  The line of credit is collateralized by trade accounts
receivable and inventory, and the terms of the line of credit restrict the
Purchaser from paying cash dividends.

     The Seller also agreed, for a period of twenty-four months from the closing
date, and subject certain exceptions, not to compete with the Company in the
Business. The Purchaser intends to account for the transaction as a purchase.
