Item 2. Acquisition or Disposition of Assets.

On April 20, 1999, Bolt Technology Corporation, (the "Company"), a Connecticut
corporation, acquired A-G Geophysical Products, Inc.  ("AG").  This acquisition
was effected by the Company acquiring all of the outstanding stock of A-G from
Albert H. Gerrans, Jr., Stephen Clay and Robert Bernard.  A-G is a leading
developer and manufacturer of patented underwater electrical connectors and
cables, air gun signature hydrophones and pressure transducers for the marine
seismic industry.

The aggregate consideration paid by the Company in respect of the acquisition
described above was $13.6 million and consisted of $6.1 million of cash, 63,492
shares of the Company's common stock valued at $0.5 million and note to Mr.
Gerrans for $7.0 million.  The Company used its cash  to fund the cash portion
of the consideration.

The purchase price for shares of A-G capital stock was determined through arms'
length negotiations between management of the Company on the one hand and A-G
and A-G's stockholders on the other hand.  Neither A-G nor its stockholders had
any material relationship prior to acquisition with the Company, any affiliates
of the Company, any director or officer of the Company or any associate of any
such director or officer.

To effect the acquisition certain terms and financial covenants of the Company's
unsecured line of credit with Fleet National Bank were modified.
