Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2):

On April 19, 2010, H.B. Fuller Company (the “Company”) entered into a Credit Agreement with JP Morgan Chase Bank, N.A., as administrative agent, and Citibank, N.A., as syndication agent, and various financial institutions (the “Credit Agreement”). The Credit Agreement establishes a $200 million unsecured multi-currency revolving credit facility (the “Credit Facility”) that the Company can draw upon for general corporate purposes. The Credit Agreement includes an accordion feature which allows the Company, at its option, to increase the aggregate amount of the Credit Facility by up to $75 million subject to customary conditions. The Credit Facility replaces the Company’s existing revolving credit facilities and expires on June 19, 2013, at which time the revolving credit loans mature. The Credit Agreement allows the Company to borrow at interest rates that vary based on, at the Company’s option (i) a spread over the greatest of the prime rate, the federal funds effective rate from time to time plus one-half of one percent, and the Adjusted LIBO Rate for a one month interest period plus one percent, or (ii) a spread over the rate at which Eurocurrency deposits in the London interbank market for specified periods are quoted by Reuters or, in the case of borrowings not denominated in U.S. Dollars, with reference to the British Bankers Association Interest Settlement Rates, adjusted for reserve and other regulatory requirements. The interest rate spread is determined by the Company’s debt rating.

The Credit Facility contains covenants that are customary for similar credit arrangements, including covenants relating to financial reporting and notification, payment of indebtedness, taxes and other obligations, and compliance with applicable laws. There are also financial covenants that require the Company to maintain an interest coverage ratio (defined as the ratio of Consolidated EBITDA to Consolidated Interest Expense for the period of the four most recent consecutive fiscal quarters) of not less than 2.5 to 1.0 and a leverage ratio (defined as the ratio of Consolidated Total Indebtedness to Consolidated EBITDA for the period of the four most recent consecutive fiscal quarters) of no greater than 3.5 to 1.0. The Credit Facility also imposes certain customary limitations and requirements on the Company with respect to the incurrence of indebtedness and liens, investments, mergers, acquisitions and dispositions of assets.

Amounts due under the Credit Facility may be accelerated upon an Event of Default as defined in the Credit Facility, such as breach of a representation, covenant or agreement of the Company or the occurrence of bankruptcy, if not otherwise waived or cured.

The foregoing description of the Credit Facility is not complete and is qualified in its entirety by reference to the Credit Facility, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference. Also, the Company’s press release dated April 19, 2010, is furnished as Exhibit 99.1 and incorporated by reference in this Current Report on Form 8-K.

Contemporaneously with its execution and delivery of the Credit Agreement, the Company entered into an Amendment No. 2, dated as of April 19, 2010 (the “Amendment”), to the Loan Agreement dated as of June 19, 2006, among the Company, JPMorgan Chase Bank, N.A., as Administrative Agent, and various financial institutions (the “Loan Agreement”). The Amendment amends certain definitions, covenants and other provisions of the Loan Agreement to conform them to the terms of the Credit Agreement.

The foregoing description of Amendment No. 2 to the Loan Agreement is not complete and is qualified in its entirety by reference to Amendment No. 2, which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated by reference.
