CONDENSED NOTES TO SCHEDULE I

1. Basis of Presentation:

PQ Holdings Inc. is a holding company that conducts substantially all of its business operations through its wholly owned subsidiary, PQ Corporation. As specified in certain of PQ Corporation’s debt agreements, there are restrictions, subject to certain baskets, on the ability of PQ Corporation to make payments to its stockholder, PQ Holdings, Inc., on behalf of its equity interests (refer to Note 13 to our Consolidated Financial Statements entitled “Long-term Debt”). Accordingly, these condensed financial statements have been presented on a “parent-only” basis. Under a parent-only presentation, PQ Holdings Inc.’s investment in its consolidated subsidiary is presented under the equity method of accounting. These parent-only financial statements should be read in conjunction with PQ Holdings Inc.’s audited Consolidated Financial Statements included elsewhere herein.

2. Restricted Net Assets:

Schedule I of Article 5-04 of Regulation S-X requires that the condensed financial information of registrant shall be filed when the restricted net assets of consolidated subsidiaries exceed 25 percent of consolidated net assets as of the end of the most recently completed fiscal year. For purposes of the above test, restricted net assets of consolidated subsidiaries shall mean that amount of the registrant’s proportionate share of net assets of consolidated subsidiaries (after intercompany eliminations) which as of the end of the most recent fiscal year may not be transferred to the parent company by subsidiaries in the form of loans, advances or cash dividends without the consent of a third party (i.e., lender, regulatory agency, foreign government, etc.).
