Item 2. Acquisition or Disposition of Assets.

      On September 14, 1999 (the "Effective Date"), Louisiana-Pacific
Acquisition Inc. (the "Offeror"), a wholly owned subsidiary of Louisiana-Pacific
Corporation ("Louisiana-Pacific"), completed a tender offer (the "Offer") for
all outstanding shares ("Shares") of Le Groupe Forex Inc., a Quebec company
("Forex"), at Cdn. $33.00 per Share (the "Offer Consideration"). The Offeror
acquired approximately 95.9% of the outstanding Shares in the Offer.
Louisiana-Pacific intends to take appropriate steps to acquire all untendered
Shares at the same price as promptly as practicable. The Offer was made pursuant
to a Circular Bid, a copy of which (excluding certain schedules thereto) is
filed as Exhibit 99.1 to this report and incorporated herein by this reference.

      Louisiana-Pacific agreed to make the Offer, directly or through a wholly
owned subsidiary, pursuant to an amended and restated support agreement, dated
August 12, 1999 (the "Support Agreement"), between Louisiana- Pacific and Forex.
Concurrently with entering into the Support Agreement, Louisiana-Pacific entered
into an amended and restated lock-up agreement (the "Lock-Up Agreement") with
certain persons (collectively, the "Shareholder Group") who owned approximately
42.4% of the Shares outstanding (on a fully diluted basis). Pursuant to the
Lock-Up Agreement, the members of the Shareholder Group agreed, among other
things, to tender their Shares pursuant to the Offer. The Support Agreement and
the Lock-up Agreement are filed as Exhibits 2.1 and 2.2, respectively, to this
report and incorporated herein by this reference.

      The Offer Consideration was determined through arm's-length negotiations
between representatives of Louisiana-Pacific and representatives of Forex and
the Shareholder Group. The aggregate purchase price for all Shares is
approximately Cdn. $760,000,000 (U.S. $517,000,000 on the basis of the exchange
rate in effect on the Effective Date). With respect to Shares purchased in the
Offer, approximately Cdn. $524,000,000 was paid on the Effective Date and
approximately Cdn. $198,000,000 is payable in four equal annual installments,
together with interest thereon. The portion, if any, of the purchase price for
untendered Shares that will be payable on a deferred basis had not been
determined as of the date of this report.

      Funding of the portion of the Offer Consideration paid on the Effective
Date was provided from a combination of Louisiana-Pacific's existing cash
balances and borrowings under a new $300 million loan facility with Bank of
America, N.A. and a new $250 million loan facility with Centric Capital
Corporation. The agreements under which these loan facilities were made
available are filed as Exhibits 99.2 and 99.3, respectively, to this report and
incorporated herein by this reference.

      Forex is one of the largest North American producers of oriented strand
board. Forex's tangible assets include land, buildings and improvements,
machinery and equipment and furniture and fixtures. Louisiana-Pacific presently
intends, in general, to continue using such assets in the conduct of
Louisiana-Pacific's oriented strand board business.

Item 5. Other Events.

      On August 24, 1999, Louisiana-Pacific issued a press release announcing
its agreement to purchase Evans Forest Products, Ltd. A copy of the press
release is filed as Exhibit 99.4 to this report and is incorporated herein by
this reference.
