An Executive Loan Program offering loans to key executives to assist them in purchasing LP Common Stock was put in place in November 1999. The Sarbanes-Oxley Act of 2002 generally prohibits the extension of new personal loans to directors and executive officers and the amendment of existing loans. No new loans have been permitted under the program since January 2001.

Initially, up to 1,700,000 shares of Common Stock were offered by LP for purchase prior to January 23, 2000, by LPÕs executive officers and selected key management personnel designated by its Chief Executive Officer. In November 2000, the subcommittee of the Compensation Committee authorized additional loans under the Executive Loan Program during the 60-day period which ended January 23, 2001. Participants were permitted to borrow up to 100% of the purchase price of the shares to be purchased, which was equal to the closing price of the Common Stock on the NYSE on the date of delivery of an election to participate to LP. The maximum amount an individual was permitted to borrow was three times his or her annual base pay. The loans were unsecured and, for executive officers, bore interest at the annual rate of 6.02%.

On January 23, 2004, 100% of the principal and interest outstanding at that date under the program was forgiven. One-half of the principal amount was forgiven under provisions requiring continuous employment by LP through that date and the other half of the principal and all accrued interest was forgiven because the share price target of $20.00 was attained during the 12 months prior to that date. The share price target of $20.00 was established November 24, 2000, at which time LPÕs share price was $7.38. The loan forgiveness provisions applicable to executive officers also required that the executive continue to own all shares purchased under the Executive Loan Program through the date of forgiveness.

Mr. Lee C. Simpson served as President and Chief Operating Officer of Louisiana-Pacific Corporation on an interim basis from July 1995 until March 1996 and an executive officer from 1972 until his retirement in 1991.

The following table provides information regarding loans outstanding under the Executive Loan Program to persons who were executive officers of LP at any time during 2004. The loan amounts shown include the original principal amount, the number of shares purchased and the price at which they were purchased, and the amount outstanding on January 23, 2004, on which date all remaining loan balances were forgiven and the program was terminated.

The maturity date of interest and principal on loans made under the Executive Loan Program was January 23, 2006. Principal and interest was due in full 30 days following the executive's resignation or involuntary termination of employment prior to January 23, 2006, subject to various provisions providing for forgiveness of all or a portion of the loans if conditions relating to continued employment or trading prices for the Common Stock were met. On January 23, 2004, 100% of the principal and interest outstanding at that date under the program was forgiven. One-half of the principal amount was forgiven under provisions requiring continuous employment by LP through that date and the other half of the principal and all accrued interest was forgiven because the share price target of $20.00 was attained during the 12 months prior to that date.

3/17/2003 Proxy Information

In November 2002, Robert M. Simpson, the son of one of LP's directors, Lee C. Simpson, purchased from LP a parcel of real property that was previously the site of an LP sawmill for $175,000 in cash. Robert Simpson also assumed and indemnified LP against all environmental commitments and liabilities with respect to the site. The sale price was determined by LP's Director of Real Estate, Neil Sherman, based on an appraisal in 2001 by a third party appraiser in the amount of $250,000, which did not take into account environmental issues or the cost of removing existing improvements, and Mr. Sherman's assessment of fair value given the offsetting costs and liabilities associated with acquisition of the property on an "as is" basis. The Board of Directors, with Lee C. Simpson abstaining, determined that the proposed sale terms were fair to LP.

Terry Simpson, also a son of Lee C. Simpson, was an employee of LP until July 31, 2002, and received compensation totaling $218,008 during 2002.

During 2002, LP used, and is continuing to use during 2003, the legal services of Jones Day, of which Mr. McCartan, a director of LP, is a partner.
