Re:      TOR Minerals International, Inc. (the "Company")
Nasdaq Symbol: TORM

Dear Mr. Parker:

In its Proxy Statement filed on April 16, 2008, the Company indicated that John J. Buckley, a member of the Company's Board of Directors and the Audit Committee, passed away on April 8, 2008.  Accordingly, the Company no longer complies with Nasdaq's audit committee requirements as set forth in Marketplace Rule 4350.

However, consistent with Marketplace Rule 4350(d)(4), Nasdaq will provide the Company a cure period in order to regain compliance as follows:

•           until the earlier of the Company's next annual shareholders' meeting or April 8, 2009; or

•           if the next annual shareholders' meeting is held before October 6, 2008, then the Company must evidence compliance no later than October 6, 2008.

The Company must submit to Nasdaq documentation, including biographies of any new directors, evidencing compliance with the rules no later than this date. In the event the Company does not regain compliance by this date, Nasdaq rules require Staff to provide written notification to the Company that its securities will be delisted. At that time, the Company may appeal the delisting determination to a Listing Qualifications Panel.

Marketplace Rule 4803(a) requires that the Company, as promptly as possible but no later than four business days from the receipt of this letter, make a public announcement through the news media which discloses receipt of this letter and the Nasdaq rules upon which it is based.¹ The Company must provide a copy of this announcement to Nasdaq's MarketWatch Department, the Listing Qualifications Department, and the Listing Qualifications Hearings Department (the "Hearings Department") at least

¹ We also note that Item 3.01 of Form 8-K requires disclosure of the receipt of this notification within four business days.

See, SEC Release No. 34-49424.
