STAMFORD, CT, July 7, 2010 – Silgan Holdings Inc.

pay dividends, repurchase stock and incur additional debt. Although not obligated, the Company could use funds from the new credit facility to redeem its 6 ³/4% Senior Subordinated Notes due 2013.

The term loans provided under the new credit facility refinanced the term loans under the prior credit facility, and the excess proceeds from the new term loans may be used by the Company for general corporate purposes including acquisitions, stock repurchases and refinancing of other debt. The new term loans mature on July 7, 2016. The Company may use revolving loans under the new credit facility for working capital and other general corporate purposes including acquisitions, stock repurchases and refinancing of other debt. The revolving loan facility matures on July 7, 2015. The new credit facility also provides the Company with an incremental uncommitted multicurrency loan facility for up to an additional US $450 million, which may be used to finance acquisitions and for other permitted purposes.

Under the new credit facility, the interest rate for US dollar loans will be either LIBOR or the base rate under the new credit facility plus a margin, the interest rate for Euro loans will be the Euribor rate under the new credit facility plus a margin and the interest rate for Canadian dollar loans will be either the Bankers’ Acceptance discount rate or the Canadian prime rate under the new credit facility plus a margin. Initially, for term loans and revolving loans maintained as LIBOR, Euribor or Bankers’ Acceptance loans the margin will be 2.25% and for term loans and revolving loans maintained as base rate or prime rate loans the margin will be 1.25%. The margins for term loans and revolving loans are subject to adjustment quarterly based upon financial ratios.

As a result of the incremental borrowings and higher interest rates under the new credit facility, the Company is revising its current estimate of full year 2010 adjusted net income per diluted share down by $0.07 to a range of $2.10 to $2.20. In addition, the Company expects to record a charge of approximately $0.04 per diluted share for the loss on early extinguishment of debt in connection with this refinancing.
