Item 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On November 16, 2004, CTS Corporation ("CTS") entered into a merger
agreement (the "Merger Agreement") with SMTEK International, Inc. ("SMTEK")
providing for a merger of Cardinal Acquisition, Inc., a Delaware corporation and
a wholly owned subsidiary of CTS into SMTEK. In the merger, SMTEK will become a
wholly owned subsidiary of CTS.

         At the effective time of the merger, SMTEK stockholders will be
entitled to receive in exchange for each share of SMTEK common stock (1) $10.725
in cash and (2) a number of shares of CTS common stock equal to $3.575, subject
to adjustment as described below, divided by the volume weighted average price
of CTS common stock for the 20 consecutive trading days in the period ending on
the trading day immediately prior to the effective time of the merger (the
"Closing VWAP"), up to a maximum exchange ratio described below.

         If the volume weighted average price of CTS common stock for the 20
consecutive trading days in the period beginning on the trading day immediately
following the date of the Merger Agreement (the "Post-Signing VWAP) is greater
than the volume weighted average price of CTS common stock for the 20
consecutive trading days in the period ending on the trading day immediately
prior to the date of the Merger Agreement, which is $13.4329 (the "Pre-Signing
VWAP), the value of the stock component of the merger consideration will be
increased by 25% of the difference, up to a maximum increase of $0.70, or no
more than $4.275 worth of CTS common stock.

         If the Pre-Signing VWAP is greater than the Post-Signing VWAP, the
value of the stock component of the merger consideration will be decreased by
25% of the difference, up to a maximum decrease of $0.10, or no less than $3.475
worth of CTS common stock. Based upon the foregoing, the total value of the
merger consideration will be between $14.20 and $15.00 per share of SMTEK common
stock if the maximum exchange ratio, as described below, is not reached.

         Under the Merger Agreement, CTS is not required to issue a number of
new shares of CTS common stock that would require CTS to obtain stockholder
approval for such issuance (the "Issuance Cap"). CTS stockholder approval would
be required under Indiana law if CTS were to issue a number of shares greater
than 20% of the number of shares of CTS common stock outstanding at the
effective time of the merger. As of September 26, 2004, there were approximately
35,900,000 shares of CTS common stock outstanding. Thus, CTS could issue up to
approximately 7,144,000 shares of CTS common stock without needing stockholder
approval. Based on the number of shares of SMTEK common stock currently
outstanding, approximately 2,700,000, the maximum exchange ratio would be
approximately 2.646.

         Based on the current $3.575 value of the stock component of the merger
consideration and the Pre-Signing VWAP of $13.4329, the current exchange ratio
would be approximately 0.266. Based on the current $3.575 value of the stock
component of the merger consideration, the Closing VWAP would have to be equal
to or less than approximately $1.35 to reach the Issuance Cap. The closing
prices of CTS and SMTEK shares on Tuesday, November 16, 2004, were $13.45 and
$13.07, respectively.

         If the number of shares of CTS common stock that would have been issued
but for the Issuance Cap exceeds the Issuance Cap, SMTEK may elect, in its sole
discretion, either to (i)



proceed with the merger with the cap on the number of shares to be issued, (ii)
terminate the Merger Agreement and receive $900,000 break up fee from CTS or
(iii) receive the merger consideration all in cash. If SMTEK elects to receive
the merger consideration all in cash, CTS may elect instead to terminate the
Merger Agreement and pay SMTEK a break up fee of $3.5 million.

         The receipt of CTS common stock in the merger is expected to be taxable
for U.S. federal income tax purposes. The completion of the merger is subject to
approval by the stockholders of SMTEK and the satisfaction of customary
conditions.

         In connection with the Merger Agreement, the controlling stockholder of
SMTEK entered into an agreement pursuant to which, among other things, he agreed
to vote in favor of the merger. Thomas Wheeler and certain related trusts
beneficially own approximately 33% of SMTEK's common stock. SMTEK has also
agreed in the Merger Agreement to use its reasonable best efforts to have
another significant stockholder enter into a similar agreement with CTS.
