Portola International

Notice of Future Press Release & Conference Call

January 12, 2006, Batavia, Illinois – Portola Packaging, Inc. announces that it has postponed the 1st quarter fiscal year 2006 earnings call scheduled for later today.

The Company established a Management Deferred Compensation Plan and a Rabbi trust in December 1996 to allow deferrals of compensation by employees beginning in 1997. The plan allowed employees to elect to defer a portion of their compensation each year. This Plan had been given off balance sheet treatment. In December 2005, the Company’s Board of Directors approved the dissolution of the Management Deferred Compensation Plan due to an Internal Revenue Code Section 409A grandfather provision that allowed deferred compensation plans to be terminated without penalties if they were terminated by December 31, 2005. The plan was dissolved in December and the liabilities of the plan exceeded the assets by $275,000. Approximately $250,000 of this shortfall occurred prior to our August 31, 2005 fiscal year end. The Company has proposed to our outside auditors, PricewaterhouseCoopers (PWC), that since this prior period amount of approximately $250,000 is insignificant, we record the entire expense in our first quarter ending November 30, 2005. We are currently awaiting their decision. Although this is not a significant dollar amount, Portola Management is trying to make sure this issue is completely resolved before releasing our November 30, 2005 1st Quarter results. We will announce a re-scheduled earnings call before the end of the day Friday. We apologize for any inconvenience this may have caused.

Any questions should be directed to Michael Morefield at 630-326-2074.
