Item 1. Security and Subject Company.

   The name of the subject company is TJ International, Inc., a Delaware
corporation (the "Company"). The address of the principal executive offices of
the Company is 200 East Mallard Drive, Boise, Idaho 83706. The title of the
class of equity securities to which this Statement relates is the Company's
Common Stock, par value $1.00 per share ("Common Stock"), and the associated
preferred share purchase rights (the "Rights") issued pursuant to the Company's
Rights Agreement, dated as of August 26, 1999, between the Company and First
Chicago Trust Company of New York, as rights agent. The tender offer described
in Item 2 of this Statement is also for the Company's ESOP Convertible
Preferred Stock, par value $1.00 per share ("Preferred Stock" and, together
with Common Stock, "Capital Stock"), and each share of Preferred Stock
generally is convertible into one share of Common Stock. Preferred Stock is
held by the trustee for the employee stock ownership plan portion of the
Company's Investment Plan, and Preferred Stock is not registered under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). This
Statement relates only to Preferred Stock to the extent it is converted into
Common Stock pursuant to its terms.

Item 2. Tender Offer of the Bidder.

   This Statement relates to the tender offer by WTJ, Inc. (the "Purchaser"),
which is a wholly owned subsidiary of Weyerhaeuser Company, a Washington
corporation ("Weyerhaeuser"), to purchase all of the outstanding (i) shares of
Common Stock ("Common Shares"), and associated Rights, at a price per Common
Share of $42, and (ii) shares of Preferred Stock ("Preferred Shares" and,
together with Common Shares, "Shares") at a price per Preferred Share of $42,
in each case, net to the seller in cash, without interest thereon (the "Offer
Price"), upon the terms and subject to the conditions set forth in the Offer to
Purchase, dated November 30, 1999, and in the related Letter of Transmittal
(which, together with amendments or supplements hereto or thereto, collectively
constitute the "Offer"). The Offer is disclosed in a Tender Offer Statement on
Schedule 14D-1, dated November 30, 1999 (the "Schedule 14D-1"), as filed with
the Securities and Exchange Commission (the "Commission"). The Offer is being
implemented pursuant to the Agreement and Plan of Merger, dated as of November
23, 1999, among Weyerhaeuser, the Purchaser and the Company (the "Merger
Agreement") providing for a tender offer, which is to be followed by the merger
of the Purchaser into the Company (the "Merger"), with the Company as the
surviving corporation of the Merger becoming a wholly owned subsidiary of
Weyerhaeuser. The Offer to Purchase states that the principal executive offices
of the Purchaser and Weyerhaeuser are located at 33663 Weyerhaeuser Way South,
Federal Way, Washington 98003.

Item 3. Identity and Background.

   (a) The name and business address of the Company, which is the person filing
this Statement, are set forth in Item 1 above.

   (b) On November 23, 1999, the Company, the Purchaser and Weyerhaeuser
entered into the Merger Agreement which provides, among other things, for the
price to be paid pursuant to the Offer to be $42 per Share, net to the seller
in cash without interest thereon, and, subject to certain conditions, for the
Merger following consummation of the Offer. In the Merger, each issued and
outstanding Common Share (other than Common Shares held by Weyerhaeuser, the
Purchaser, any subsidiary of Weyerhaeuser other than the Purchaser, in the
treasury of the Company or by any subsidiary of the Company, and Common Shares
held by stockholders, if any, who perfect their dissenters' rights under
Delaware law, but including each Common Share issued upon the automatic
conversion of Preferred Shares pursuant to their terms immediately prior to the
effective time of the Merger) will be converted into the right to receive the
Offer Price in cash.

   The Merger Agreement also provides, among other things, that if the Merger
Agreement is terminated under certain circumstances involving a withdrawal,
modification or change of recommendation of the Board of Directors of the
Company (the "Company Board") with respect to the Offer, or termination of the
Merger Agreement by the Company if the Company Board approves and pursues an
alternative transaction involving the Company (subject to the limitations set
forth in the Merger Agreement), the Company will be required to pay
Weyerhaeuser a termination fee of up to $25,000,000.
<PAGE>

   A description of the Merger Agreement is contained in Section 12 of the
Offer to Purchase, dated November 30, 1999, which is filed as Exhibit 1 to the
Schedule 14D-9 and which description is incorporated herein by reference. The
Offer to Purchase is being mailed to the Company's stockholders together with
this Statement. Such description is qualified in its entirety by reference to
the Merger Agreement, a copy of which is filed as Exhibit 2 to this Statement
and is incorporated herein by reference.

   Certain contracts, agreements, arrangements and understandings between the
Company and certain of its executive officers, directors and affiliates are
described in Annex A to this Statement, which description is incorporated
herein by reference.

   The Company has a Severance Pay Plan that provides for severance benefits to
employees (other than the executive officers) who are terminated in certain
circumstances. The amount of the benefit is a specified number of weeks' pay,
depending upon how long the terminated employee has worked for the Company. In
connection with entering into the Merger Agreement, Weyerhaeuser and the
Company agreed to amend the severance pay formula under the Company's Severance
Pay Plan so that the severance payable to participants who become entitled to
severance under the Company's Severance Pay Plan as a result of termination of
employment after the purchase of Shares in the Offer will be increased by eight
weeks.

Item 4. The Solicitation or Recommendation.

   (a) and (b) Background; Recommendation of the Company Board; Reasons. On
September 30, 1991, the Company entered into the Limited Partnership Agreement,
as amended (the "Partnership Agreement"), with MacMillan Bloedel of America,
Inc. ("MBA"). Under the Partnership Agreement, Trus Joist MacMillan A Limited
Partnership, a Delaware limited partnership (the "Partnership") was formed.
Substantially all of the current business of the Company is conducted through
the Partnership. The Company contributed its North American engineered lumber
products business to the Partnership in exchange for general and limited
partnership interests representing a 51% interest in the Partnership issued to
the Company. MBA, a wholly owned subsidiary of MacMillan Bloedel Limited, a
corporation existing under the laws of Canada ("MB"), contributed all of its
and MB's North American engineered lumber technology and manufacturing
facilities, and entered into a long-term distribution arrangement, in exchange
for a 49% limited partnership interest in the Partnership issued to MBA.

   On September 27, 1997, W. Thomas Stephens became the President and Chief
Executive Officer of MB, succeeding Robert Findlay, who retired; Mr. Findlay,
who also was on the Company Board, resigned thereafter from the Company Board
and was not replaced. Subsequently, from time to time, Mr. Stephens and Thomas
H. Denig, President and Chief Executive Officer of the Company, had discussions
regarding possible alternatives for the Partnership, although the Company
continually expressed its preference for maintaining the Partnership in its
current form.

   On June 11, 1999, Mr. William R. Corbin, Executive Vice President of
Weyerhaeuser, and Mr. Keith Purchase, Executive Vice President and Chief
Operating Officer of MB, met with Mr. Denig to inform him that Weyerhaeuser was
pursuing a transaction with MB that, if completed, would result in MB becoming
a wholly owned subsidiary of Weyerhaeuser (the "MB Transaction"). At this
meeting, Mr. Purchase proposed that the Company waive any right that it might
have to purchase MBA's 49% interest in the Partnership as a result of the MB
Transaction.

   On June 13 and June 14, 1999, Mr. Steven R. Rogel, President and Chief
Executive Officer of Weyerhaeuser, and Mr. Denig had telephone conversations
regarding the anticipated MB Transaction and its potential impact on the
Partnership. Mr. Denig stated that the Company had retained financial and legal
advisors to assist the Company in analyzing its options in light of the
proposed MB Transaction. Mr. Rogel stated that Weyerhaeuser did not believe
that the consummation of the MB Transaction would give rise to any rights of
the Company under the Partnership Agreement. Mr. Denig, however, stated that
the Company believed that the MB Transaction would give the Company the rights
provided in the Partnership Agreement upon a change of control of a partner,
including the right to purchase MBA's interest in the Partnership. Messrs.
Rogel and Denig agreed that they should arrange meetings with other senior
officers of their respective companies to

                                       2
<PAGE>

discuss the future of the Partnership after the MB Transaction. Mr. Denig
suggested that the two companies enter into a confidentiality and standstill
agreement before discussing the various options that might be available and
sent a form of agreement to Mr. Rogel on June 14, 1999. This confidentiality
and standstill agreement was never executed by Weyerhaeuser.

   Following the June 14, 1999 telephone conversation between Messrs. Rogel and
Denig, there were conversations between Goldman, Sachs & Co. ("Goldman Sachs"),
the Company's financial advisor, and Morgan Stanley & Co. ("Morgan Stanley"),
Weyerhaeuser's financial advisor regarding these matters.

   Messrs. Rogel and Denig spoke again by telephone on June 17, 1999 regarding
the conversations between the financial advisors to the two companies and the
confidentiality and standstill agreement proposed by the Company. Mr. Rogel
stated that Weyerhaeuser was not willing to enter into such a confidentiality
and standstill agreement. Mr. Denig stated that, after consulting with members
of the Company Board, he did not believe that consolidation with Weyerhaeuser
was the Company's preferred alternative, but that he would take any compelling
proposal by Weyerhaeuser to acquire the Company to the Company Board for
consideration. In addition, Mr. Denig indicated that, absent such a
transaction, the Company would determine what alternatives to pursue under the
Partnership Agreement.

   On June 20, 1999, Weyerhaeuser, an indirect wholly owned subsidiary of
Weyerhaeuser and MB entered into a merger agreement (the "MB Agreement")
providing for the MB Transaction. On June 21, 1999, the proposed MB Transaction
was publicly announced by Weyerhaeuser and MB.

   Later on June 21, 1999, the Company issued a press release announcing that
it was evaluating its options in light of the announcement of the MB
Transaction. In its press release, the Company indicated that, under the terms
of the Partnership Agreement, the Company had certain rights upon a change of
control of MBA. The Company noted that it believed that the MB Transaction
triggered those rights and that, if those rights were triggered, the Company
would have the right to purchase MBA's 49% interest in the Partnership without
a takeover premium, or have the right to sell the Company's 51% interest to
Weyerhaeuser as the acquirer of MB with a takeover premium. The Company also
noted that it also could allow Weyerhaeuser to assume MB's rights and
obligations under the Partnership Agreement and that it was evaluating its
options under the Partnership Agreement and otherwise in order to determine the
most advantageous option for its stockholders, associates, customers and
suppliers.

   On July 7, 1999, Messrs. Rogel and Denig met in Seattle, Washington, with
Mr. Corbin and Mr. Jody B. Olson, Vice President of the Company, to discuss the
future of the Partnership, strategies for growth of the Partnership's business,
and the future relationships between the Company, Weyerhaeuser and MB. Mr.
Denig stated that, although the Company was still reviewing its alternatives
and no decision had been reached, in his view there were three viable
alternatives for the Company: the Company would purchase MBA's 49% Partnership
interest, Weyerhaeuser would acquire the Company, or MBA would agree to
significantly reduce its interest in the Partnership and relinquish certain
rights under the Partnership Agreement.

   On July 22, 1999, Messrs. Rogel, Denig and Olson and Mr. William C. Stivers,
Executive Vice President and Chief Financial Officer of Weyerhaeuser, met in
Seattle, Washington. The Weyerhaeuser representatives stated that an
acquisition of the Company was Weyerhaeuser's strongly preferred alternative
and indicated that Weyerhaeuser was considering a purchase price for all
outstanding Shares in the mid-$30's range. The Weyerhaeuser representatives
indicated that, although Weyerhaeuser preferred a cash transaction, it would be
willing to consider a tax-deferred transaction with the Company involving
Weyerhaeuser stock. At this meeting, in addition to discussing other
alternatives, Messrs. Denig and Olson proposed a structure in which the Company
would acquire MBA's Partnership interest on a tax-advantaged basis to
Weyerhaeuser. Subsequent to this meeting, representatives of the Company and
Weyerhaeuser and their respective financial, legal and tax advisors had
discussions regarding the alternative proposed by Messrs. Denig and Olson for
the Company to acquire MBA's Partnership interest on a tax-advantaged basis,
and, subsequently, Morgan Stanley informed Goldman Sachs that Weyerhaeuser had
no interest in pursuing such a transaction.

                                       3
<PAGE>

   On September 3, 1999, Messrs. Rogel and Corbin met with Messrs. Denig and
Olson in Boise, Idaho. Mr. Rogel stated that Weyerhaeuser did not agree with
the Company's assessment of alternatives available to the parties and stated
that continuation of the Partnership in its current form also should be
considered. They again stated that Weyerhaeuser did not agree that the Company
would have an option to purchase MBA's Partnership interest as a result of the
MB Transaction. Mr. Rogel emphasized the strategic importance to Weyerhaeuser
of the engineered wood products business and stated that Weyerhaeuser would be
prepared to offer $36 per Share to acquire all the outstanding Shares of the
Company. Mr. Denig stated that he did not view that offer as compelling
compared to the other alternatives he believed were available to the Company,
and suggested that the respective financial advisors to the two companies meet
to discuss the business and operational assumptions underlying their respective
valuations of the Company. Mr. Denig also indicated that the Company would
continue to work on the alternative of exercising its rights under the
Partnership Agreement to acquire MBA's Partnership interest, but that he did
not believe that the continuation of the Partnership in its current form
following consummation of the MB Transaction would be an acceptable alternative
for the Company and its stockholders, given Weyerhaeuser's potential influence
on the Company in such a circumstance.

   On September 21 and October 1, 1999, the financial advisors to the Company
and the financial advisors to Weyerhaeuser met to discuss their respective
views on valuation. During this period, Goldman Sachs advised Morgan Stanley
that the Company did not intend to pursue a transaction at $36 per Share in
light of its other alternatives. On October 11, 1999, Morgan Stanley advised
Goldman Sachs in a telephone call that Weyerhaeuser did not intend to discuss
any changes in its proposal to acquire the Company until it received the
Company's view as to an appropriate acquisition price. Morgan Stanley further
stated that Weyerhaeuser wished to wait until after the MB Transaction was
consummated to pursue any further discussions with the Company. In a telephone
conversation with Mr. Denig on October 19, 1999, Mr. Rogel reiterated these
statements.

   During this period, the financial advisors to the Company and the financial
advisors to Weyerhaueser continued to discuss valuation issues and the Company
and its advisors continued to review the alternatives the Company believed were
available under the Partnership Agreement and continued to focus on exercising
the right under the Partnership Agreement to buy out MBA's Partnership interest
following consummation of the MB Transaction. In addition, the Company
contacted and engaged in discussions with potential financing sources that
could assist the Company in exercising its purchase right under the Partnership
Agreement. In mid-October, the Company's management and financial and legal
advisors updated the Company Board as to the status of discussions between the
Company and Weyerhaeuser and discussed other alternatives available to the
Company. On October 19, 1999, when the Company announced its third quarter
earnings and noted that Weyerhaeuser's acquisition of MB was scheduled to close
in early November 1999, the Company stated that it was in the final stages of
evaluating its options under the Partnership Agreement and otherwise in order
to determine the most advantageous option for the Company's shareholders,
associates, customers, and suppliers and that it intended to disclose its plans
for the Partnership in mid-November 1999.

   The MB Transaction was consummated on November 1, 1999. On the evening of
November 1, 1999, Messrs. Stivers, Rogel and Corbin met with Messrs. Denig and
Olson and Ms. Valerie A. Heusinkveld, Vice President and Chief Financial
Officer of the Company, in Seattle, Washington. At this meeting, the Company
representatives discussed certain of the assumptions underlying Weyerhaeuser's
$36 per Share proposal. The Company's representatives presented reasons why
they believed a higher price was justified for the Shares. At the end of this
meeting, Messrs. Rogel and Denig met separately and Mr. Rogel proposed a $40
per Share price to acquire the Company. Mr. Denig indicated that he would not
be willing to support such a proposal.

   On November 3, 1999, Mr. Denig invited Mr. Rogel to visit the Company's
Deerwood, Minnesota facility the following weekend in order to show the
potential value of a transaction. On November 7, 1999, during the visit to the
Deerwood, Minnesota facility, Messrs. Rogel and Denig again discussed the
acquisition of the

                                       4
<PAGE>

Company by Weyerhaeuser, and Mr. Denig indicated that he might be prepared to
support a transaction at $43 per Share. Mr. Rogel indicated that Weyerhaeuser
was not prepared to increase its price above $40 per Share, although it would
be willing to consider using consideration consisting of 50% Weyerhaeuser stock
and 50% cash in lieu of an all-cash transaction. Mr. Denig also indicated that
the Company Board would be meeting on November 11, 1999 and that he would
inform the Company Board of his most recent discussions with Mr. Rogel.

   On November 10, 1999, Mr. Rogel sent the following letter to Mr. Denig:

   Mr. Tom Denig
   TJ International
   200 East Mallard Drive
   Boise, ID 83706

   Dear Tom:

  Following our recent discussions regarding the combination of TJ
  International (TJI) and Weyerhaeuser Company (Weyerhaeuser), I wanted to
  reemphasize, on behalf of Weyerhaeuser and its board of directors, our
  strong interest in pursuing a transaction between our two companies. We
  believe that the combination of our companies is mutually beneficial for
  all of our shareholders. As we discussed, in order to avoid any
  miscommunication, I felt it important to commit to paper the proposal we
  are making.

  After carefully considering all of the information discussed in our various
  meetings and taking into account all of the potential synergies and
  operating improvements that are realistically achievable, we propose to
  purchase TJI for cash at a price of $40.00 for each share of TJI common
  stock. Alternatively, as you have indicated a preference for a stock
  component, we also would consider a transaction with one-half of the
  consideration in cash and one-half in Weyerhaeuser common stock. This
  alternative transaction would be structured as a cash tender at $40.00 for
  half of the outstanding TJI common stock followed by a second step merger
  of 0.6375 shares of Weyerhaeuser common stock for each remaining share of
  TJI common stock, based on Weyerhaeuser's closing price yesterday of
  $62.75. This proposal assumes there are approximately 18.3 million shares
  of TJI common stock outstanding on a fully diluted basis.

  We believe this offer creates superior value for your shareholders versus
  other options available to TJI. This significant premium we are offering
  represents an upfront payment to your shareholders for the synergies and
  operating improvements we expect to achieve. Our proposal represents a 30%
  premium to the closing price of TJI common stock on November 9, 1999, and a
  50% premium to TJI's stock price before the announcement of our merger with
  Macmillan Bloedel. In addition, our offer represents substantial premiums
  of 50%, 52% and 81% to TJI's l-, 2- and 5-year average stock prices,
  respectively, as well as a meaningful premium to the long-term price
  targets of research analysts who cover TJI. In addition to the premium, if
  a component of Weyerhaeuser common stock is included, TJI shareholders
  would have a tax-deferred transaction on the stock received, a currency
  with significant liquidity, and an enhanced dividend with pickup of more
  than 130%. TJI shareholders who choose to receive common stock will also
  benefit from the substantial upside in Weyerhaeuser common stock as we
  realize benefits from the pulp and paper cycle as well as the benefits from
  our recent merger with MacMillan Bloedel and a combination with TJI.

  In analyzing your business, we have adopted an aggressive view of the
  future prospects for engineered wood products and TJI's position in the
  market. We have projected operating parameters that exceed TJI's historical
  performance. Given the strategic alliance between Weyerhaeuser and TJI
  signed in 1993 and the close working relationship between our two
  companies, we believe we have fully accounted for all potential synergies.
  Furthermore, now that we have completed our transaction with MacMillan
  Bloedel, Weyerhaeuser is responsible for distributing and providing in-
  market support for products generating over

                                       5
<PAGE>

  60% of your revenues, a system that would be time consuming and difficult
  to replicate. For these and other reasons, we are convinced that a
  combination of TJI and Weyerhaeuser will generate the highest value for TJI
  shareholders relative to any other alternative.

  As we indicated in recent meetings, and you and I discussed this past
  Monday, this price reflects our full valuation of TJI and is not
  negotiable. We are willing to proceed at this price only if we can achieve
  a prompt, negotiated transaction. We are prepared to negotiate a definitive
  merger agreement with you and to commence a tender offer quickly. To that
  end we are in position to promptly deliver the merger agreement once we
  hear back affirmatively from you after your board meeting. We could
  concurrently commence our confirmatory due diligence process which we
  expect could be completed within one week with your full cooperation. As
  part of the agreement, we will require the strong and full commitment of
  insiders to this transaction, customary no-shop provisions and a break-up
  fee of $30 million. We anticipate the transaction will be subject only to
  customary closing conditions, including regulatory approvals and
  clearances.

  Given the significance to TJI of our proposal, the premium to TJI's recent
  and historical trading prices and the strategic alternatives available to
  TJI, we expect that our proposal will be carefully considered by the TJI
  board.

   We look forward to hearing from you shortly.

                                  Very truly yours,

                                  /s/ Steven R. Rogel
                                  Steven R. Rogel
                                  Chairman, President & CEO

   At a meeting of the Company Board on November 11, 1999, the Company Board
discussed with the Company's management and financial and legal advisors the
proposal made by Weyerhaeuser, as well as possible alternatives to a
transaction with Weyerhaeuser, including exercising the Company's rights under
the Partnership Agreement to acquire MBA's Partnership interest. The Company
Board agreed to continue discussions with Weyerhaeuser, as well as to continue
its pursuit of other alternatives under the Partnership Agreement. Following
the conclusion of the meeting of the Company Board, two outside directors
selected by the Company Board (Dan R. Nelson and J. L. Scott) contacted Mr.
Rogel to indicate that, if Weyerhaeuser was prepared to increase the price in
its proposal to $42 per Share, in their view this price would have the support
of the Company Board; these directors did not discuss any of the other
conditions set forth in the Weyerhaeuser letter, dated November 10, 1999.

   On November 12, 1999, Mr. Rogel called Mr. Scott to advise him that he would
discuss a $42 per Share price with the Board of Directors of Weyerhaeuser on
November 15, 1999 and that he would be in a position to respond on November 16,
1999. Mr. Rogel stated that any increase by Weyerhaeuser above its proposed
price of $40 per Share would have to be on an all-cash basis.

   On November 15, 1999, the Board of Directors of Weyerhaeuser approved a cash
offer price of $42 per Share.

   On November 16, 1999, Mr. Rogel called Mr. Scott and stated that
Weyerhaeuser was willing to offer $42 per Share in an all-cash transaction. Mr.
Rogel then called Mr. Denig and confirmed Weyerhaeuser's willingness to proceed
with a transaction on this basis.

   Later on November 16, 1999, Mr. Rogel sent the following letter to Mr.
Denig:

   Mr. Tom Denig
   TJ International
   200 East Mallard Drive
   Boise, ID 83706

   Dear Tom:

  Following up on my conversation earlier today with Joe Scott, I wanted to
  reemphasize Weyerhaeuser Company's strong interest in pursuing a
  combination with TJ International (TJI). The Weyerhaeuser Company
  (Weyerhaeuser) board has unanimously authorized me to pursue a transaction
  between our two companies and is convinced that the union would further
  strengthen our combined leadership position in the engineered wood products
  market.

  After thorough consideration and based on the terms outlined below, we have
  agreed to meet your price for TJI of $42.00 per share, payable solely in
  cash. As we discussed on the phone this morning, this meets the price you
  provided me to receive strong and unanimous board support for a cash
  transaction on the terms we have proposed. We believe this represents an
  extremely compelling transaction for your shareholders based on its
  substantial premium to TJI's recent and historical share price.

  The transaction would be structured as a cash tender offer for all of the
  outstanding common and preferred shares, followed by a second step merger
  for the remaining shares. In order to move quickly to completion, the
  Weyerhaeuser team is in place and prepared to commence confirmatory due
  diligence immediately. We would expect that with TJI's full cooperation a
  definitive agreement could be signed and announced next Monday as you
  suggested.

  In consideration for increasing our bid to $42.00 per share, Weyerhaeuser
  expects to receive the following terms (all of which are detailed in the
  draft merger agreement):

  .  Strong support from TJI's insiders including shareholder agreements
     locking up insider shares;

  .  A break-up fee of $30 million payable under customary circumstances;

  .  A customary no-shop provision; and

  .  A waiver of any buy/sell rights TJI may have under the Partnership
     Agreement as a result of the MacMillan-Bloedel transaction.

  An important reason why our Board is willing to increase the price to
  $42.00 per share is the ability to complete the tender offer and merger in
  approximately six weeks versus the several month process to complete the
  second step merger if a stockholder vote is required. In order to ensure
  the acquisition of 90% of each class of TJI's stock, the draft merger
  agreement will require a "share top up" provision. In addition, we will
  need to obtain and review a copy of TJI's ESOP Plan, which is not publicly
  available. Furthermore we expect full cooperation from TJI in structuring
  the transaction so that the ESOP and the ESOP convertible preferred stock
  does not limit our ability to use the "short form" merger procedure.

  As soon as we have confirmation from you following your Board meeting this
  morning, we will deliver a draft merger agreement. We believe it is in the
  best interests of both our companies for our discussions to be kept on a
  strictly confidential basis.

                                       7

  We have been impressed by the strength of the management team and the
  significant steps you have taken to position the company for future growth.
  We are excited about the prospects of acquiring such an outstanding company
  with strong brand and product recognition. I believe a combination of TJI
  and Weyerhaeuser will create the leading engineered wood products company
  in the world.

                                  Very truly yours,

                                  /s/ Steven R. Rogel
                                  Steven R. Rogel
                                  Chairman, President & CEO

   At a meeting of the Company Board held on November 16, 1999, following its
review of various alternatives and the November 16, 1999 letter from
Weyerhaeuser with the Company's management and the Company's financial and
legal advisors, the Company Board instructed Mr. Denig, senior management, and
the Company's financial and legal advisors, to proceed with negotiations with
Weyerhaeuser, but indicated that certain of the conditions stipulated by
Weyerhaeuser, which included a $30,000,000 break-up fee, lock-up agreements
with certain inside stockholders and waiver of the Company's right to
repurchase MBA's Partnership interest, needed to be further negotiated, and
were, as a whole, unacceptable to the Company Board. In addition, the Company
Board indicated that, if the Company was going to permit Weyerhaeuser to
undertake due diligence, Weyerhaeuser would need to enter into a customary form
of confidentiality agreement. Subsequent to the November 16, 1999 meeting of
the Company Board, Mr. Denig informed Mr. Rogel that the Company was prepared
to proceed with negotiation of a transaction at $42 per Share, assuming that
the parties could agree to a mutually acceptable merger agreement.

   Later that evening, Weyerhaeuser and the Company entered into a
confidentiality agreement covering nonpublic information to be provided to
Weyerhaeuser by the Company beginning on November 17, 1999. This
confidentiality agreement did not contain any standstill provisions restricting
a unilateral offer by Weyerhaeuser. A copy of such confidentiality agreement is
filed as Exhibit 3 to this Statement.

   On November 16, 1999, counsel to Weyerhaeuser provided counsel to the
Company with a draft form of merger agreement. During the period from November
17 until November 23, 1999, representatives of Weyerhaeuser and the Company and
their respective financial and legal advisors negotiated the terms of the
merger agreement, and Weyerhaeuser held meetings on November 17 and 18, 1999 in
Boise, Idaho to conduct a due diligence investigation of the Company.

   On November 22, 1999, the Company Board held a special meeting to consider
the proposed acquisition of the Company by Weyerhaeuser. (From November 11,
1999 through November 22, 1999, the Company Board met seven times with the
Company's management and its advisors.) At the meeting on November 22, 1999
Mr. Denig and the Company's senior management reviewed the status of the
proposed transaction with Weyerhaeuser and discussed with the directors of the
Company management's views regarding the proposed transaction, representatives
of Goldman Sachs made a financial presentation concerning the proposed
transaction, the Company's legal advisors outlined the terms of the proposed
transaction, and the Company Board and its advisors discussed the proposed
transaction with Weyerhaeuser and alternatives thereto. At this meeting,
Goldman Sachs delivered its oral opinion to the Company Board that, as of such
date, subject to finalization of definitive documentation, and based upon and
subject to assumptions made, matters considered and limitations in connection
with the opinion, the $42 per Common Share in cash proposed to be paid by the
Purchaser in the Offer and the Merger to the holders of Common Shares was fair
from a financial point of view to such holders. Goldman Sachs subsequently
delivered its written opinion dated November 23, 1999. The entire text of the
opinion of Goldman Sachs provided to the Company Board regarding the Offer and
the Merger, which sets forth assumptions made, matters considered and
limitations in connection with such opinion, is attached as Annex B to this
Statement, and the Company stockholders are urged to read such opinion in its
entirety. At the special meeting, the Company Board approved and adopted the
Merger

                                       8
<PAGE>

Agreement and the related transactions by unanimous vote, determined that the
transactions contemplated by the Merger Agreement, including the Offer and the
Merger, were fair to the Company and its stockholders from a financial point of
view, and also declared the Merger Agreement to be advisable. THE COMPANY BOARD
RECOMMENDS THAT THE COMPANY'S STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES PURSUANT TO THE OFFER. The Company Board also recommends that the
Company's stockholders vote to adopt the Merger Agreement to the extent
required by applicable law. A copy of the letter to the Company's stockholders
communicating the Company Board's recommendation and the joint press release
issued by the Company and Weyerhaeuser on November 23, 1999, are filed as
Exhibits 4 and 5 to this Statement and are incorporated herein by reference.

   At the November 22, 1999 meeting of the Company Board, the Company Board
also approved the Offer and the Merger for the purposes of rendering Section
203 of the Delaware General Corporation Law and Article Tenth of the Company
Certificate of Incorporation, as amended (the "Company's Certificate")
inapplicable (A) to Weyerhaeuser and the Purchaser solely by reason of their
entering into the Merger Agreement or consummating the Offer or the Merger or
the grant or exercise of an option (the "Option") (which the Company granted to
the Purchaser pursuant to the Merger Agreement to allow the Purchaser
(following consummation of the Offer) to purchase for a price of $42 per Common
Share in cash a number of Common Shares equal to the number of Common Shares
that, when added to the number of Common Shares owned by Weyerhaeuser and the
Purchaser immediately prior to its exercise of the Option, would result in the
Purchaser owning 90% of the then-outstanding Common Shares); and (B) to the
Offer, the Merger and the other transactions contemplated by the Merger
Agreement. The Company Board further approved and adopted an amendment to the
Rights Agreement, filed as Exhibit 7 to this Statement, providing for, among
other things, changes to the definition of the terms "Acquiring Person," "Share
Acquisition Date," and "Distribution Date," and a change in the final
expiration date, and in doing so ensured that the Rights Agreement will not be
applicable to the Offer, the Merger or any of the other transactions
contemplated by the Merger Agreement, and providing for expiration of the
Rights Agreement immediately prior to the Merger.

   In reaching the conclusions and recommendations described above, the Company
Board considered a number of factors, including, without limitation, the
following:

     (i) The terms and conditions of the Offer, the Merger and the Merger
  Agreement, including the price to be paid in the Offer and the Merger, and
  the fact that, although the Offer could be consummated as early as the end
  of December of 1999, Weyerhaeuser had agreed to consummate the Offer as
  early as the first week of January 2000 if all of the conditions to the
  Offer were satisfied;

     (ii) The terms of the Partnership Agreement, and the various
  alternatives available to the Company under the terms of the Partnership
  Agreement and otherwise. The Company and the Company Board believed that
  consummation of the MB Transaction by Weyerhaeuser constituted an "Event of
  Default" under the Partnership Agreement and evaluated the Company's
  alternatives accordingly, although the Company and the Company Board
  recognized that Weyerhaeuser could contest such belief and engage in
  litigation that could delay the Company's ability to assert its rights
  under the Partnership Agreement;

     (iii) The fact that, following Weyerhaeuser's acquisition of MB,
  Weyerhaeuser was the Partnership's largest customer, responsible for more
  than 60% of the Company's annual revenues;

     (iv) The potential disruption of the Partnership by Weyerhaeuser (and
  the effect of such disruption on the Company) should Weyerhaeuser use any
  of its rights under the Partnership Agreement to frustrate the Company's
  intentions for the Partnership, and the possibility that, over time,
  Weyerhaeuser might on its own enter into businesses directly competitive
  with the Company;

     (v) The fact that, under the terms of the Merger Agreement, a third
  party interested in pursuing a transaction with the Company would have the
  certainty of being able to acquire MBA's 49% interest in the Partnership
  for $700,000,000 (approximately equivalent to the price of $42 per Share),
  if such third party were willing to pay more for the Company than
  Weyerhaeuser was willing to pay, as opposed to the uncertain price that
  would need to be determined under the terms of the Partnership Agreement
  and the

                                       9
<PAGE>

  uncertain timing for any such determination. The Company Board also
  considered the fact that any such third party, even if they were to acquire
  the entire Partnership, would have to renegotiate the distribution
  arrangements between Weyerhaeuser and the Partnership;

     (vi) The oral opinion of Goldman Sachs delivered to the Company Board at
  its November 22, 1999 meeting, that, as of such date subject to
  finalization of definitive documentation, and based upon and subject to the
  assumptions made, matters considered and limitations in connection with
  such opinion, the $42 per Common Share in cash proposed to be paid by the
  Purchaser in the Offer and the Merger to the holders of Common Shares was
  fair from a financial point of view to such holders (the entire text of the
  written opinion of Goldman Sachs dated November 23, 1999 subsequently
  delivered to the Company Board regarding the Offer and the Merger, which
  sets forth assumptions made, matters considered, and limitations in
  connection with such opinion, is attached as Annex B to this Statement, and
  stockholders are urged to read such opinion in its entirety);

     (vii) The recommendation of the Company's management that the Merger
  Agreement, including the Offer and the Merger, be approved;

     (viii) The directors' knowledge of the Company's business, financial
  condition, results of operations, current business strategy and future
  prospects, the nature of the markets in which the Partnership operates,
  including the Partnership's growth prospects, the Partnership's position in
  such markets, and Weyerhaeuser's position in such markets;

     (ix) Possible alternatives to the Offer and the Merger, the value to the
  Company's stockholders of such alternatives and the timing and likelihood
  of achieving additional value from these alternatives, and the possibility
  that equally suitable partners for merger and consolidation would be
  available. In this connection, the Company Board considered the fact that,
  since the Company issued its press release on June 21, 1999 regarding its
  evaluation of alternatives under the Partnership Agreement and otherwise,
  no third parties had contacted the Company expressing any significant
  interest in pursuing a transaction with the Company. The Company Board also
  considered that fact that it had not explicitly put the Company up for sale
  in light of the provisions set forth in the Partnership Agreement (relating
  to the fact that a change of control of the Company would be an "Event of
  Default" under the Partnership Agreement), and the difficulties that such
  an announcement could have created with the Company's associates, customers
  and suppliers. The Company Board also considered the possibility of
  remaining an independent company with Weyerhaeuser as its partner in the
  Partnership. The Company also had discussed Weyerhaeuser's willingness to
  reduce its interest in the Partnership, which would give the Company
  greater autonomy over the Partnership, which Weyerhaeuser had rejected. The
  Company Board concluded that the transactions contemplated by the Merger
  Agreement, including the Offer and the Merger, were superior to such
  alternatives, and that, if a superior alternative did become available, the
  Company would be able to pursue such an alternative under the terms of the
  Merger Agreement; and

     (x) The historical and current market prices for Common Shares.

   The Company Board also considered certain countervailing factors in its
deliberations concerning the Merger Agreement, the Offer and the Merger,
including:

     (i) The terms and conditions of the Merger Agreement, including the
  requirement under the Merger Agreement that the Company pay to Weyerhaeuser
  termination fees of up to $25,000,000 if the Merger Agreement is terminated
  under certain circumstances specified in the Merger Agreement, including,
  among others, if the Company Board changed its recommendation or exercised
  its right to terminate the Merger Agreement and enter into an alternative
  transaction. While the Company Board thought that these provisions could
  result in significant fees being borne by the Company, it accepted these
  provisions as a means to obtain other terms favorable to the Company, in
  particular, the right to negotiate or exchange information with potential
  bidders and the right to terminate the Merger Agreement, under certain
  limited

                                       10
<PAGE>

  circumstances set forth in the Merger Agreement, in the event of an
  alternative transaction that the Company Board determined would be superior
  to the transaction with Weyerhaeuser.

     (ii) The fact that, under the Merger Agreement, it was delaying the
  exercise and/or waiving certain rights that it believed the Company
  possessed under the Partnership Agreement to buy MBA's 49% interest in the
  Partnership, or to sell to Weyerhaeuser (through its ownership of MB) the
  Company's interest in the Partnership. The Company Board accepted these
  provisions, both as a means to obtain other terms favorable to the Company,
  and because it believed that an attempt to exercise these rights would be
  less favorable to the Company and its stockholders than negotiating an
  agreement to sell the Company to Weyerhaeuser at a price of $42 per Share,
  given, among other things, that Weyerhaeuser refused to admit that the
  Company had such rights and that Weyerhaeuser was the Partnership's most
  significant customer and distributor.

   The foregoing discussion of the information and factors considered and given
weight by the Company Board is not intended to be exhaustive. In view of the
variety of factors considered in connection with its evaluation of the Offer,
the Company Board did not find it practicable to, and did not, quantify or
otherwise assign relative weights to the specific factors considered in
reaching its determination. In addition, individual members of the Company
Board may have given different weights to different factors.

Item 5. Persons Retained, Employed or To Be Compensated.

   Pursuant to a letter agreement dated June 16, 1999, the Company engaged
Goldman Sachs to act as its financial advisor in connection with the Offer and
the Merger. Pursuant to the terms of the letter agreement, the Company has
agreed to pay Goldman Sachs upon consummation of the Offer a transaction fee of
1.0% of the aggregate consideration paid or payable in connection with the
Offer and the Merger (calculated assuming all the Shares are acquired in the
Offer and including amounts paid or payable to holders of options, warrants and
other convertible securities) plus the principal amount of all indebtedness for
borrowed money as shown on the most recent consolidated balance sheet of the
Company prior to the consummation of the Offer. The Company has previously paid
Goldman Sachs $250,000 which will be deducted from the amount payable described
in the preceding sentence. The Company has agreed to reimburse Goldman Sachs
for its reasonable out-of-pocket expenses, including attorney's fees, and to
indemnify Goldman Sachs against certain liabilities, including certain
liabilities under the federal securities laws.

   Except as described above, neither the Company, nor any person acting on its
behalf, currently intends to employ, retain or compensate any other person to
make solicitations or recommendations to the Company's stockholders on its
behalf concerning the Offer.

Item 6. Recent Transactions and Intent with Respect to Securities.

   (a) To the knowledge of the Company, no discretionary transactions in Common
Stock have been effected within the past 60 days by the Company or any
executive officer, director, affiliate or subsidiary of the Company.

   (b) To the knowledge of the Company, the Company's executive officers,
directors, affiliates and subsidiaries intend to tender, pursuant to the Offer,
all Shares that are held of record or that are beneficially owned by such
persons. Harold Thomas, the Chairman of the Company, has indicated that he
intends to donate certain amounts of his Common Shares to charities and may
make other gifts prior to the consummation of the Offer as part of his estate
and tax planning.

Item 7. Certain Negotiations and Transactions by the Subject Company.

   (a) Except as set forth in this Statement, the Company is not engaged in any
negotiation in response to the Offer that relates to or would result in (i) an
extraordinary transaction, such as a merger or reorganization,

                                       11
<PAGE>

involving the Company or any subsidiary of the Company; (ii) a purchase, sale,
or transfer of a material amount of assets by the Company or any subsidiary of
the Company; (iii) a tender offer for or other acquisition of securities by or
of the Company; or (iv) any material change in the present capitalization or
dividend policy of the Company.

   (b) Except as set forth in this Statement, there are no transactions,
resolutions of the Company Board, agreements in principle, or signed contracts
in response to the Offer that relate to or would result in one or more of the
events referred to in Item 7(a) above. Subject to the terms of the Merger
Agreement incorporated by reference in Item 3(b) of this Statement, the Company
may engage in discussions or negotiations with respect to transactions or
proposals of the type referred to above in this Item 7. At its meeting held on
November 22, 1999, the Company Board determined that public disclosure with
respect to the parties to, and the possible terms of any proposals made in
connection with, or agreement that may result from, any such discussions or
negotiations, might jeopardize the continuation of such discussions or
negotiations and adopted a resolution authorizing and directing management not
to make any such public disclosure unless and until an agreement in principle
is reached relating thereto.

Item 8. Additional Information To Be Furnished.

   (a) Rights Agreement. Each Right issued pursuant to the Rights Agreement
initially entitles the registered holder thereof to purchase one one-hundredth
of a share of the Company's Series A Junior Preferred Stock, par value $1.00
per share ("Junior Preferred Shares"), of the Company at a price of $135 per
one one-hundredth of a Junior Preferred Share, subject to adjustment. On the
earlier of (i) the tenth day following a public announcement that a person or
group of affiliated or associated persons (an "Acquiring Person") has acquired,
or obtained the right to acquire, beneficial ownership of 20% or more of the
outstanding Common Shares or (ii) the tenth business day (or such later date as
may be determined by action of the Company Board prior to the time any person
becomes an Acquiring Person) following the commencement of a tender offer or
exchange offer the consummation of which would result in that person becoming
an Acquiring Person (the earlier of such dates being the "Distribution Date"),
the Rights become exercisable and trade separately from the Common Stock. After
the Distribution Date, each holder of a Right (other than the Acquiring Person)
will thereafter have the right to acquire Common Shares having a market value
of two times the exercise price of the Right; or, in certain circumstances, the
right to acquire shares of the Acquiring Person's capital stock. The Rights may
be redeemed at a price of $0.001 per Right at any time prior to a person
becoming an Acquiring Person. For a complete description of the Rights
Agreement, see the Company's Form 8-A, dated September 17, 1999, the Company's
Current Report on Form 8-K, dated September 17, 1999, and the Rights Agreement
filed as an exhibit to such Form 8-A, each as filed with the Commission and
incorporated herein by reference.

   The Company has entered into an amendment to the Rights Agreement to make it
inapplicable to the Offer, the Merger and the other transactions contemplated
by the Merger Agreement, as described in Item 4 above. In addition, this
amendment to the Rights Agreement provides that the Rights Agreement will
expire immediately prior to the Merger. A copy of such amendment to the Rights
Agreement is filed as Exhibit 7 to this Statement and incorporated herein by
reference.

   (b) Delaware General Corporation Law. As a Delaware corporation, the Company
is subject to Section 203 of the Delaware General Corporation Law ("Section
203"). In general, Section 203 would prevent an "Interested Stockholder"
(generally defined as a person beneficially owning 15% or more of a
corporation's voting stock) from engaging in a "Business Combination" (as
defined in Section 203) with a Delaware corporation for three years following
the date such person became an Interested Stockholder unless: (i) before such
person became an Interested Stockholder, the board of directors of the
corporation approved the transaction in which the Interested Stockholder became
an Interested Stockholder or approved the Business Combination, (ii) upon
consummation of the transaction that resulted in the Interested Stockholder
becoming an Interested Stockholder, the Interested Stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding, for purposes of determining the number of
shares outstanding, stock held by directors who are also officers and by
employee stock ownership plans that

                                       12
<PAGE>

do not allow plan participants to determine confidentially whether to tender
shares), or (iii) following the transaction in which such person became an
Interested Stockholder, the Business Combination is (A) approved by the board
of directors of the corporation and (B) authorized at a meeting of stockholders
by the affirmative vote of the holders of at least 66 2/3% of the outstanding
voting stock of the corporation not owned by the Interested Stockholder. In
accordance with the provisions of Section 203, the Company Board has approved
the Merger Agreement, as described in Item 4 in this Statement, and, therefore,
the restrictions of Section 203 are inapplicable to the Offer, the Merger and
the related transactions.

   (c) Idaho Control Share Acquisition Statute and Business Combination
Statute. As a corporation that does business in Idaho, has its headquarters in
Idaho and has a significant number of stockholders in Idaho, the Company has
the option to apply to itself the provisions of Section 1603 ("Section 1603")
and Section 1704 ("Section 1704") of the Idaho Corporations Code (the "ICC").
In general, Section 1603 provides that the shares of a public corporation
acquired by an acquiring person in a "control share acquisition" (generally
defined as an acquisition by an acquiring person that would otherwise, when
added to all other shares of the public corporation beneficially owned by the
acquiring person, entitle the acquiring person to increase such acquiring
person's voting power into a new range of voting power (with those ranges being
20-33 1/3%, 33 1/3% to 50%, and over 50%)) have voting rights limited to the
extent that such an acquisition has not been approved by resolution of holders
of 66 2/3% of the voting power of the corporation. In general, Section 1704
prevents an "interested shareholder" (generally defined as a person
beneficially owning 10% or more of a corporation's voting stock) from engaging
in a "Business Combination" (as defined in Section 1701 of the ICC) with such a
corporation for three years following the date such person became an interested
shareholder unless the business combination or the acquisition of shares made
by the interested shareholder on the date such interested shareholder becomes
such is approved by a committee of the board of directors of the public
corporation consisting of "disinterested directors" before such date. The
Company Board has not amended the Company Bylaws to make either Section 1603 or
Section 1704 applicable to the Company.

   (d) Article Tenth of Charter. In general, Article Tenth of the Company's
Certificate ("Article Tenth") would prevent an "Interested Stockholder"
(generally defined as a person beneficially owning 5% or more of the Common
Shares) from engaging in a "Business Combination" (as defined in Article Tenth)
with the Company unless such Business Combination is approved by the
affirmative vote or consent of the holders of at least a majority of the then-
outstanding Common Shares, excluding those Common Shares beneficially owned by
any Interested Stockholder or any affiliate of any Interested Stockholder. The
Company Board has taken action sufficient to render Article Tenth inapplicable
(A) to Weyerhaeuser, and the Purchaser solely by reason of their entering into
the Merger Agreement or consummating the Offer or the Merger or the grant or
exercise of the Option; and (B) to the Offer, the Merger and the other
transactions contemplated by the Merger Agreement.

   (e) Antitrust.

   United States. Under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), and the rules that have been promulgated
thereunder by the Federal Trade Commission (the "FTC"), certain acquisition
transactions may not be consummated unless certain information has been
furnished to the Antitrust Division of the United States Department of Justice
(the "Antitrust Division") and the FTC and certain waiting period requirements
have been satisfied. The acquisition of Shares by the Purchaser pursuant to the
Offer is subject to such requirements. Pursuant to the requirements of the HSR
Act, Weyerhaeuser and the Company intend to file their respective required
Notification and Report Forms (the "Forms") with the Antitrust Division and the
FTC in early December of 1999. The statutory waiting period applicable to the
purchase of Shares pursuant to the Offer is scheduled to expire at 11:59 P.M.,
New York City time, on the 15th day after Weyerhaeuser has filed its Form,
unless early termination of the waiting period is granted or Weyerhaeuser and
the Company receive a request for additional information or documentary
material prior thereto. However, prior to such date, the Antitrust Division or
the FTC may extend the waiting period by requesting additional information or
documentary material relevant to the acquisition. If such a request is made,
the waiting period will be extended until 11:59 P.M., New York City time, on
the tenth day after substantial

                                       13
<PAGE>

compliance by Weyerhaeuser with such request, unless earlier terminated by the
Antitrust Division or the FTC or the filing parties voluntarily agree to extend
further the waiting period. Thereafter, such waiting periods can be extended
only by court order. In practice, complying with a request for additional
information or documentary material can take a significant amount of time. In
addition, if the Antitrust Division or the FTC raises substantive issues in
connection with a proposed transaction, the parties frequently engage in
negotiations with the relevant governmental agency concerning possible means of
addressing those issues and may agree to delay consummation of the transaction
while such negotiations continue. Expiration or termination of the applicable
waiting period under the HSR Act is a condition to the Purchaser's obligation
to accept for payment and pay for Shares tendered pursuant to the Offer.
Pursuant to the HSR Act, Weyerhaeuser will request early termination of the
applicable waiting period. There can be no assurance that the waiting period
will be terminated early.

   The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions. At any time before or after the
consummation of any such transaction, the Antitrust Division or the FTC could,
notwithstanding termination of the waiting period, take such action under the
antitrust laws as either deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of Shares pursuant to the Offer,
seeking divestiture of the Shares so acquired or divestiture of substantial
assets of Weyerhaeuser or the Company, or seeking the imposition of unfavorable
conditions on the proposed transaction. Private parties and states may also
bring legal actions under the antitrust laws under certain circumstances.
Although Weyerhaeuser currently owns a 49% interest in the Partnership, there
can be no assurance that a challenge to the Offer on antitrust grounds will not
be made, or, if such a challenge is made, what the result will be.

   Canadian Competition Act. Under the provisions of the Competition Act
(Canada) (the "Canadian Act"), the acquisition of Shares under the Offer may be
consummated after the expiration of a seven-calendar day waiting period
commenced by the filing by Weyerhaeuser of a short-form premerger filing under
the Canadian Act with respect to the Offer, unless Weyerhaeuser receives a
request to complete a long-form filing prior to the expiration of the seven-
calendar day waiting period, in which case a long-form filing must be made,
after completion of which a 21-day calendar day waiting period is mandated.
These waiting periods are expected to be doubled by legislative changes that
may be implemented in respect of premerger notification filings under the
Canadian Act made after mid-December 1999. Weyerhaeuser expects to make a
short-form filing under the Canadian Act in the near future. Before or after
the waiting periods referred to above have expired, upon application by the
Commissioner of Competition under the Canadian Act (the "Commissioner") which
certifies that in the Commissioner's opinion more time is required to complete
his inquiry into the Offer, the Canadian Competition Tribunal may issue an
interim order forbidding any person from, among other things, completing the
Offer. The interim order shall not have a term longer than thirty days; on
further application by the Commissioner that he is unable to complete an
inquiry within the period specified in the order because of circumstances
beyond his control, the Canadian Competition Tribunal may extend the duration
of the order to a day not more than sixty days after the order takes effect. In
the course of his inquiry, the Commissioner may request additional information.
In practice, complying with such requests can take a significant amount of
time. In addition, if the Commissioner raises substantive issues in connection
with a proposed transaction, the parties frequently engage in negotiations with
the Commissioner concerning possible means of addressing those issues and may
agree to delay consummation of the transaction while such negotiations
continue. Expiration of the applicable waiting periods under the Canadian Act
is a condition to the Purchaser's obligation to accept for payment and pay for
Shares tendered pursuant to the Offer.


   The Merger will not require an additional filing under the Canadian Act if
the Purchaser owns more than 50% of the outstanding Shares at the time of the
Merger or if the Merger is completed within one year after the making of the
premerger notification filings under the Canadian Act.

   The Commissioner frequently scrutinizes the legality under the Canadian Act
of transactions such as the Purchaser's proposed acquisition of the Company. At
any time before or after the Purchaser's acquisition of

                                       14
<PAGE>

Shares pursuant to the Offer, the Commissioner could take such action under the
Canadian Act as he deems necessary or desirable in the public interest,
including seeking to enjoin the purchase of Shares pursuant to the Offer or the
consummation of the Merger or seeking the divestiture of Shares acquired by the
Purchaser or the divestiture of substantial assets of the Company or its
subsidiaries or Weyerhaeuser or its subsidiaries. Although Weyerhaeuser
currently owns a 49% interest in the Partnership, there can be no assurance
that a challenge to the Offer under the Canadian Act will not be made or, if
such a challenge is made, of the result thereof.

   Other Foreign Laws. The Company and certain of its subsidiaries conduct
business in several foreign countries where regulatory filings or approvals may
be required or desirable in connection with the consummation of the Offer.
Certain of such filings or approvals, if required or desirable, may not be made
or obtained prior to the expiration of the Offer. The Purchaser is seeking
further information regarding the applicability of any such laws and currently
intends to take such action as may be required or desirable.

   (f) Purchaser's Designation of Persons To Be Elected to the Company
Board. The Information Statement attached as Annex A to this Statement is being
furnished in connection with the possible designation by the Purchaser,
pursuant to the terms of the Merger Agreement, of certain persons to be
appointed to the Company Board other than at a meeting of the Company's
stockholders.

                       INFORMATION STATEMENT PURSUANT TO
                  SECTION 14(f) OF THE SECURITIES EXCHANGE ACT
                       OF 1934 AND RULE 14f-1 THEREUNDER

   This Information Statement is being mailed on or about November 30, 1999 as
part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Statement") of TJ International, Inc. (the "Company"). You are receiving this
Information Statement in connection with the possible election of persons
designated by Weyerhaeuser Company ("Weyerhaeuser") to a majority of seats on
the Board of Directors of the Company (the "Company Board"). On November 23,
1999, the Company entered into the Agreement and Plan of Merger (the "Merger
Agreement") with Weyerhaeuser and WTJ Inc., a Delaware corporation and a wholly
owned subsidiary of Weyerhaeuser (the "Purchaser"), pursuant to which the
Purchaser is required to commence a tender offer to purchase (i) all issued and
outstanding shares of the Company's Common Stock, par value $1.00 per share
(the "Common Shares"), and associated Rights (as defined below), at a price per
Common Share of $42, and (ii) all the issued and outstanding shares and,
together with the Common Shares (the "Shares"), of the Company's ESOP
Convertible Preferred Stock, par value $1.00 per share (the "Preferred Shares")
at a price per Preferred Share of $42, in each case, net to the seller in cash,
without interest thereon (the "Offer Price"), upon the terms and conditions set
forth in the Offer to Purchase and in the related Letter of Transmittal (which,
together with amendments and supplements hereto or thereto, collectively
constitute the "Offer"). Copies of the Offer to Purchase and the Letter of
Transmittal have been mailed to the Company's stockholders and are filed as
Exhibits (a)(1) and (a)(2) respectively, to the Schedule 14D-1 (as amended from
time to time, the "Schedule 14D-1") filed by Weyerhaeuser and the Purchaser
with the Securities and Exchange Commission (the "Commission"), and the Offer
to Purchase is also filed as Exhibit 1 to this Statement. The Merger Agreement
contemplates that, following consummation of the Offer and the satisfaction or
waiver of certain conditions, Purchaser will be merged with and into the
Company (the "Merger"), with the Company as the surviving corporation of the
Merger becoming a wholly owned subsidiary of Weyerhaeuser. As of the effective
time of the Merger, each issued and outstanding Share (other than Common Shares
owned by the Company, Weyerhaeuser, the Purchaser or their respective
subsidiaries, and Common Shares as to which appraisal rights have been
perfected) will, by virtue of the Merger and without any action by the holder
thereof, be converted into the right to receive the Offer Price in cash, as
more fully set forth in the Merger Agreement.

   The Offer, the Merger and the Merger Agreement are more fully described in
the Offer to Purchase as well as in the Statement to which this Information
Statement forms Annex A, which was filed by the Company with the Commission on
November 30, 1999 and which is being mailed to the Company's stockholders along
with this Information Statement.

   This Information Statement is being mailed to you in accordance with Section
14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
and Rule 14f-1 promulgated thereunder. The information set forth herein
supplements certain information set forth in the Statement. Information set
forth herein related to Weyerhaeuser, the Purchaser or the Purchaser Designees
(as defined below) has been provided by Weyerhaeuser. You are urged to read
this Information Statement carefully. You are not, however, required to take
any action.

   Pursuant to the Merger Agreement, Weyerhaeuser and the Purchaser commenced
the Offer on November 30, 1999. The Offer is currently scheduled to expire at
8:00 PM, New York City time, on January 5, 2000, unless Weyerhaeuser extends
it.

                                      A-1
<PAGE>

                                    GENERAL

   The Common Shares and the Preferred Shares are the only classes of equity
securities of the Company outstanding. The holders of Preferred Shares are
entitled to vote on all matters submitted to a vote of the Company's
stockholders, voting together with the holders of Common Shares as one class.
The holder of each Preferred Share is entitled to the same voting power that
the holder of one Common Share holds, which in all cases is equal to one vote.
As of the close of business on November 17, 1999, there were outstanding
18,351,054 Common Shares, and Weyerhaeuser and the Purchaser own no Common
Shares as of the date hereof.

             RIGHTS TO DESIGNATE DIRECTORS AND PURCHASER DESIGNEES

   The Merger Agreement provides that, promptly upon the acceptance for payment
of, and payment by the Purchaser for, any Shares pursuant to the Offer, the
Purchaser shall be entitled to designate such number of directors (the
"Purchaser Designees") on the Company Board as will give the Purchaser
representation on the Company Board equal to at least that number of directors,
rounded up to the next whole number, which is the product of the total number
of directors on the Company Board multiplied by the percentage that such number
of Shares so accepted for payment and paid for by the Purchaser plus the number
of Shares otherwise owned by the Purchaser or any other subsidiary of
Weyerhaeuser bears to the number of fully diluted Shares.

   Following the election or appointment of the Purchaser Designees as
described above, and prior to the Effective Time of the Merger, the Company
Board shall have at least three directors who were directors on the date of the
Merger Agreement and who are not officers of the Company ("Independent
Directors"); and, if the number of Independent Directors is reduced below three
for any reason whatsoever, any remaining Independent Directors (or Independent
Director if only one remains) shall be entitled to designate persons to fill
such vacancies who shall be deemed to be Independent Directors for the purposes
of the Merger Agreement. If no Independent Directors remain, the other
directors shall designate three persons to fill such vacancies who are not
officers, stockholders or affiliates of the Company, Weyerhaeuser, or the
Purchaser, and such persons shall be deemed to be Independent Directors for the
purposes of the Merger Agreement.

   To the fullest extent permitted by applicable law, the Company is obligated
to take all actions requested by Weyerhaeuser necessary to effect the election
of any Purchaser Designee. In connection with the foregoing, the Company will
promptly, at the option of Weyerhaeuser, use all reasonable efforts to either
increase the size of the Company Board or obtain the resignation of such number
of its current directors as is necessary to enable the Purchaser Designees to
be elected and appointed to the Company Board as provided above.

   The Purchaser Designees will be selected by Weyerhaeuser from among the
persons listed below. Each of the following persons has consented to serve as a
director of the Company if appointed or elected. None of the Purchaser
Designees currently is a director of, or holds any positions with, the Company.
To the best of Weyerhaeuser's knowledge, except as set forth below, none of the
Purchaser Designees or any of their affiliates beneficially owns any equity
securities or rights to acquire any such securities of the Company, nor has any
such person been involved in any transaction with the Company or any of its
directors, executive officers or affiliates that is required to be disclosed
pursuant to the rules and regulations of the Commission other than with respect
to transactions between Weyerhaeuser and the Company that have been described
in the Schedule 14D-1 or the Statement.

   The name, age, present principal occupation or employment and five-year
employment history of each of the persons are set forth below. Unless otherwise
indicated, each such person has held his or her present position as set forth
below for the past five years and each occupation refers to employment with
Weyerhaeuser unless otherwise noted. Unless otherwise noted, each such person
is a citizen of the United States, and the business address of each person
listed below is 33663 Weyerhaeuser Way South, Federal Way, Washington 98003.

(1)  The beneficial ownership information for Trimark Financial Corporation
     ("TFC"), is taken from a Commission Schedule 13G report, Amendment No. 3,
     dated February 16, 1999. Certain TFC mutual funds, which are trusts
     organized under the laws of Ontario, Canada, are owners of record of
     1,690,000 shares of Common Stock. Robert C. Krembil, a Canadian citizen
     and Chairman and stockholder of TFC, is also an owner of record of 20,000
     shares of Common Stock. Trimark Investment Management, Inc. ("TIMI"), a
     corporation incorporated under the laws of Canada, is the manager and
     trustee of the mutual funds. TIMI is qualified to act as an investment
     advisor and manager of the mutual funds in the province of Ontario
     pursuant to the registration under the Securities Act (Ontario). TFC is a
     corporation incorporated under the laws of Ontario, Canada. It owns 100%
     of the voting equity securities of TIMI. Consequently, TFC may be deemed
     to be the beneficial owner of the securities.

(2)  The number of Common Shares shown includes Common Shares that are
     individually or jointly owned, as well as Common Shares over which the
     individual has either sole or shared investment or voting authority.
     Harold E. Thomas disclaims beneficial ownership of some of the Common
     Shares included in the table, as follows: 44,236 Common Shares held in a
     non-profit private foundation established for charitable, religious, or
     educational purposes, and 100,056 Common Shares held in trust. The table
     does not include

                                      A-4
<PAGE>

   168,000 Common Shares owned by several Thomas family trusts for the benefit
   of Mr. Thomas' grandchildren because the trust agreements do not permit him
   to exercise voting or investment power; and he disclaims beneficial
   ownership of these Common Shares. Because of their relationship, however, he
   may influence the exercise of those powers by Mr. J. Robert Tullis, former
   member of the Company Board and Trustee of the trusts.

(3)  Reflects the number of Common Shares that could be purchased by exercise
     of options available on November 22, 1999 or within 60 days thereafter
     under the Company's stock option plans.

(4)  Based on the number of Common Shares outstanding on November 22, 1999.

(5)  The amount beneficially owned by all directors and executive officers as a
     group includes 1,837,958 shares of Common Stock held by the Trustee for
     the Company's United States retirement plans. All of the executive
     officers participate in these plans; and certain of the Company's
     employees administer these plans.

(6)  In May 1983, the Company's stockholders approved a stock purchase and
     resale agreement between the Company and four of the Company's
     stockholders ("Stockholders"), consisting of Mr. Thomas and his wife,
     Phyllis S. Thomas, and Mr. Troutner and Katherine Troutner, Mr. Troutner's
     former wife. The agreement provides that, upon the death of a Stockholder,
     the Company is required to purchase (or arrange for someone else to
     purchase) one-half of the total number of Common Shares owned by such
     Stockholder at the date of death. In addition, the Company has the option
     to purchase (or arrange for someone else to purchase) all or any part of
     the remaining Common Shares owned by such Stockholder. The estate of the
     Stockholder is required to sell the Common Shares in such circumstances.
     The agreement also provides that during the lifetime of the Stockholders,
     the Company has the right of first refusal with respect to voluntary or
     involuntary transfers of Common Shares owned by any of the Stockholders,
     with certain exceptions. Any purchase price is based on average trading
     prices on the Nasdaq National Market for specified periods of time prior
     to the purchase. In connection with its approval of the Merger Agreement,
     the Company waived the obligations of the Stockholders to sell their
     shares to the Company pursuant to the stock purchase and resale agreement
     for the period that the Merger Agreement is in effect.

Preferred Stock

   In September 1990, the Company issued 634,921 Preferred Shares (equivalent,
after giving effect to a subsequent stock split, to 1,269,842 Preferred Shares)
at $11.8125 per share to the Company's employee retirement plan (the
"Investment Plan"). Each share of Preferred Stock has one vote and receives a
preferential dividend of $1.065 each year. The Company may redeem the Preferred
Stock under certain circumstances. When any person receives a payout from the
Investment Plan, the Company first converts each share of Preferred Stock into
one share of Common Stock. If the current stock price is below $11.8125, the
shares of Preferred Stock are valued at $11.8125 per share. The Company then
has the choice to pay the participant in Common Stock, cash, or any combination
of Common Stock and cash. As of November 22, 1999, 100% of the Preferred Stock,
or 1,097,719 shares of Preferred Stock, was held by the Trustee for the
Investment Plan. All of the Company's executive officers participate in the
Investment Plan; and certain of the Company's employees administer the
Investment Plan.

Director Compensation

   Cash Compensation. During 1998, each director who was not an officer
received fees of $3,600 per year, with each Committee Chairperson receiving an
additional $3,600 per year. Both of these fees were paid in semi-annual
installments of $1,800 each. Each director also received $2,000 for each
meeting of the Company Board attended in person; $500 for each committee
meeting attended in person on the same day as a meeting of the Company Board
and $1,000 for each committee meeting attended in person on a day other than
the day of a meeting of the Company Board. Fees for any meeting of the Company
Board or committee thereof attended via telephone call are one-half the regular
fees. The Company reimburses directors for any related expenses. Directors who
are also officers of the Company, Messrs. Denig and Thomas, receive no
additional compensation for service as directors.

   Stock Compensation. At the Company's 1997 annual meeting, the Company's
stockholders approved a stock plan containing both nonstatutory stock option
provisions and stock award provisions for non-employee directors. This plan
replaced the previous restricted stock plan, which stockholders had approved in
1993. The purpose of the 1997 plan was to encourage non-employee directors to
own the Company's stock, to more closely align the financial incentives of non-
employee directors with the Company's performance and stockholder's return on
investment, and to provide further incentive to outside directors to remain as
directors.

   Non-employee directors receive options to purchase 3,000 shares of Common
Stock each year of their term. The exercise price of the stock options is the
fair market value of the Common Stock on the grant date. The stock options
become exercisable in three equal annual installments, beginning one year after
the grant date. The stock options can be exercised, in whole or in part, at any
time after they become exercisable. All stock options expire, if not exercised,
ten years from the grant date.

   In addition to the stock options, non-employee directors are awarded 2,000
shares of restricted stock when first elected to the Company Board. A director
cannot take delivery of these shares, and the shares cannot be sold or pledged
for three years from the date the stock is awarded. A director vests in these
shares (the shares become non-forfeitable) in three equal annual installments,
beginning one year after the award date. If a director stops being a non-
employee director before the end of three years, the director forfeits any
shares that are not yet vested. In connection with the Merger, directors will
forfeit any shares of restricted stock that have not vested prior to the time
they cease to be directors pursuant to the terms of the Merger Agreement and
the Merger. A director has the right, starting on the award date, to receive
dividends and to vote the shares of Common Stock.

   A non-employee director who retires from service on the Company Board after
completing at least one full term on the Company Board is awarded 1,000 shares
of stock upon retirement if the director served on the Company Board for more
than four but less than nine years. If the director served on the Company Board
for nine or more years, the director is awarded 2,500 shares of stock upon
retirement.

   All stock options granted under the 1997 plan that had not previously become
exercisable became exercisable as a result of the Company entering into the
Merger Agreement.

1998 Board Meetings

   The Company Board met four times during 1998. Each director attended more
than 75% of the total number of meetings of the Company Board and of the
committees thereof on which he or she served with the exception of Mr. Jerre L.
Stead, who resigned from the Company Board at the end of his then-current term
that expired with the May 1999 annual meeting.

   Board Committees in 1998

   The Company's Board has Executive, Executive Compensation, Audit, and
Nominating and Corporate Governance Committees.

   Executive Committee. This Committee exercises virtually all the powers of
the Company Board when the Company Board is not in session, as permitted by
law. It meets whenever needed at the request of the Company management or at
the direction of the Company Board. Any action taken by this Committee is
reported to the full Board at its next regular meeting. This Committee did not
meet in 1998. The Company's Chairman and President are required by the
Company's Bylaws to be on the Committee. The current members of the Committee
are Messrs. Thomas H. Denig, J. L. Scott, Harold E. Thomas (Chairperson), and
William J. White.

   Executive Compensation Committee. This Committee reviews the Company's
general compensation strategy; establishes salaries and reviews benefit
programs for the Chief Executive Officer, those persons who report directly to
him, and other key employees; and reviews, approves, recommends and administers
the Company's incentive compensation and stock option plans. It also is
responsible for keeping abreast of compensation programs in similar businesses
in order to make sure that the Company is competitive in the recruitment and
retention of top quality employees. This Committee met twice in 1998. All
members are non-employee directors. The current members of the Committee are
Messrs. Wheelwright and White (Chairperson).

   Audit Committee. This Committee recommends appointment of the independent
auditors and reviews their independence and the arrangements for and scope of
their audit. It considers the adequacy of the Company's system of internal
accounting controls and reviews any proposed corrective actions. It reviews and
monitors the Company's policies relating to ethics and conflicts of interests.
It discusses with management and the independent auditors the Company's draft
annual financial statements and key accounting and/or reporting matters, and
reviews the activities and recommendations of the Company's internal audit
department. The Company's outside auditors and various top executives are
generally asked by the Committee Chairperson to attend the meetings as
appropriate to answer questions posed by the Committee. This Committee met
three times in 1998. All members are non-employee directors. The current
members of the Committee are Ms. Godwin, and Messrs. King, Peterson and Scott
(Chairperson).

   Nominating and Corporate Governance Committee. This Committee reviews,
advises, and makes recommendations to the full Company Board regarding nominees
to fill vacancies on the Board, as well as on the general structure,
responsibilities, and functions of the Company Board and the committees
thereof. It will consider nominations recommended by stockholders to fill
vacancies on the Company Board. Nominations by stockholders must be in writing,
submitted on a timely basis, and directed to the Secretary of the Company.
Nominations for consideration at the 2000 annual stockholders' meeting must be
received by the Company no later than December 31, 1999. (If the Offer is
consummated, the 2000 annual meeting is not expected to be held.) This
Committee met twice in 1998. The current members of the Committee are Ms.
Godwin and Mr. Wheelwright (Chairperson).

          Compensation Committee Interlocks and Insider Participation

   During 1998, there were no Executive Compensation Committee interlocks or
other comparable relationships requiring disclosure under applicable rules of
the Commission.

                       Compensation of Executive Officers

   The following sections of this Information Statement provide information
concerning the compensation the Company paid to the Company's Chief Executive
Officer and each of the four other most highly compensated executive officers
(collectively, the "Named Executives"), based on salary and incentive
compensation for 1998, as of the end of 1998.

(1) Includes compensation reduction amounts that the Company contributes to the
    Profit Sharing Plan for the benefit of the Named Executive and cash profit
    sharing distributions.
(2) Includes contributions that the Company makes to defined contribution
    retirement plans other than compensation reduction amounts described in
    note (1). The amounts reported in each year in this column represent the
    contributions that became vested during such fiscal year without regard to
    the year in which the contributions were made.
(3) Columns for "Other Annual Compensation," "Restricted Stock Award(s),"
    "Securities Underlying Options SARs," and "LTIP Payouts" are excluded
    because the Company had no such compensation items or amounts. The Company
    makes available no special fringe benefits other than stock options to
    executive officers that are not made available to all full-time employees.
    As a matter of philosophy, the Company does not provide company cars,
    subsidized travel, club memberships or like perquisites to the executive
    officer group.
(4) As described below, as part of the LTIP (as defined below), the Company
    Board set stock ownership guidelines for certain key employees, including
    the Named Executives. Each participant was given the right to purchase
    shares of Common Stock directly from the Company at the prevailing market
    price at the time of the purchase. The Company agreed, at the election of
    each participant, to lend a portion of the purchase price of the shares of
    Common Stock purchased through full-recourse, interest bearing loans to the
    participant. In January 1997, the Company made loans to the executive
    officers in the amounts shown, which, in each case, is the largest amount
    outstanding since December 31, 1996, and is the amount of principal,
    including accrued but unpaid interest through December 31, 1998,
    outstanding on March 29, 1999: Mr. Denig, $113,298.18; Mr. Dingman,
    $239,729.78; Ms. Heusinkveld, $237,790.11; Mr. Smith, $239,729.78; Mr.
    Juday, $143,837.87; Mr. Olson, $143,837.87; Mr. Ware, $143,837.87; and Mr.
    Drury, $119,864.89. The loans mature in a lump sum on December 31, 2005,
    and interest accrues each year at a variable rate equal to the "applicable
    federal rate" (the "AFR") for January of that year. Because the purchase
    price of the Common Stock was the prevailing market price, and the interest
    rate on the loans is the AFR, the Company does not impute any income to the
    participants from the loans. As noted below, as a result of the Company
    entering into the Merger Agreement, a change of control occurred under the
    plan in which the loans were issued. See "Stock Options and the Long-Term
    Incentive Program" for more information.

(1) The stock options vest 33 1/3% after one year, 66 2/3% after two years and
    100% after three years. All unexercised stock options expire ten years
    after grant date. If an optionee stops being employed by the Company, all
    stock options, whether exercisable or not, are immediately forfeited, with
    certain exceptions. These exceptions are described in this Information
    Statement. All options vested as a result of the Company's entering into
    the Merger Agreement.
(2) The grant date value is determined by the modified Black-Scholes option
    pricing model. The Company used the following assumptions: grant date
    market value per share-$27.625; option price per share-$27.625; annual
    stock volatility-.32; risk-free rate of return-6.5%; dividend yield-$.22
    per year; and, vesting adjustment-94% based on the term and vesting
    schedule described in note (1) above. The Company does not believe that any
    model can accurately determine the future value of an option because that
    value depends on future unpredictable factors. The future values realized
    may vary significantly from the values estimated by this or any other
    model. Please note that the ultimate value of the options, as well as the
    shares of stockholders, depends on actual future share values. Market
    conditions and the efforts of the directors, the officers and others to
    foster the future success of the Company can influence those future share

   Stock Options and the Long-Term Incentive Program. The Executive
Compensation Committee believes that stock ownership by management and
employees is a major incentive in building stockholder value and aligning the
interest of employees with those of the Company's stockholders. As a result,
options are granted to persons much deeper in the organization than is typical
in the industry. Other equity incentives, primarily in the form of discounted
matching stock purchase programs, are available to employees who do not
participate in the stock option program. Stock options are granted from stock
option plans approved by stockholders. Generally, stock option grants are in
the form of nonstatutory stock options.

   During the latter half of 1996, the Company implemented a new Long-Term
Incentive Program (the "LTIP"). The primary reason for the new program was to
link managers' goals and a significant portion of their compensation directly
to stockholders' interests as stockholders. There were two core elements of
this program:

  .  Stock ownership by managers. Senior managers, including the Named
     Executives, are encouraged to own at least a minimum amount of the
     Company's stock to ensure that senior managers have a significant
     personal financial stake in the future of the Company. Mr. Denig has an
     ownership guideline of two times his base salary, while all other
     participants have a guideline of one times base salary. These guideline
     amounts increase to 2.5 for Mr. Denig and 1.5 for all other participants
     at the end of 1999. If an eligible manager does not meet the minimum
     ownership guideline, no additional stock options will be granted to that
     manager until the guideline is achieved. As a transition into the new
     program, eligible managers were given the opportunity to buy the number
     of shares equal to their individual ownership guideline amount from the
     Company at market price, with a long-term, full-recourse, interest-
     bearing, nine-year, recourse loan from the Company. Loans in the amounts
     indicated on page A-10 are outstanding to executive officers in
     connection with this program. The outstanding principal balance of each
     loan is reduced upon a "change of control" to the extent that it exceeds
     the net after-tax proceeds that the executive would have received if he
     or she had sold the shares purchased with the loans on the date of the
     change of control at a price equal to the average of the high and low
     trading prices for Common Shares on that day. For these purposes, the
     effective date of the Merger Agreement, November 23, 1999, was a change
     of control. However, no reduction in any loans actually occurred because
     the outstanding principal balance of each loan was less than such net
     after-tax proceeds on that date.

  .  Annual grants of nonstatutory stock options with an exercise price equal
     to the fair market value of Common Shares on the date of grant ("FMV
     options"). The purpose in using FMV options is to reward participants
     for contributions to the Company's long-term success, measured primarily
     by increased stockholder value. These options encourage management to
     look for opportunities to increase the value of Common Shares, which
     will benefit all of the Company's stockholders. The new FMV options are
     exercisable 33 1/3% after one year, 66 2/3% after two years and 100%
     after three years. Any unexercised options expire ten years after the
     date of grant.

   If the employee ceases to be employed by the Company, all unexercised stock
options, whether exercisable or not, are generally forfeited. However, the
Company Board can accelerate the exercisability of stock options that have been
outstanding at least three years at the time a manager stops being employed if
the termination is a result of retirement at age fifty-five or older, death or
permanent or total disability, or is involuntary but not for cause. The rate of
acceleration is 100% of the eligible unvested stock options if the termination
is a result of retirement at age fifty-five or older. The rate is 3% for each
year of service for that employee in all other qualified terminations. In other
words, the Company Board could allow a 20-year employee terminating prior to
age fifty-five to exercise 60% of the otherwise unvested stock options that
have been outstanding at least three years.

   All stock options that had not previously become exercisable became
exercisable as a result of the Company's entering into the Merger Agreement.

Severance policy

   The Executive Compensation Committee determines the terms and conditions of
any severance arrangements with the Company's executive officers and key
management personnel on a case-by-case basis. The Executive Compensation
Committee takes into account the officer's tenure with the Company and his or
her responsibilities, duties, and contribution to the business and operations
of the Company.

Change of control provisions

   During 1997, the Executive Compensation Committee of the Company Board and
the full Company Board determined that appropriate steps should be taken so the
Board could expect to receive and rely on loyal service and high standards of
duty from executive officers and key employees regarding the best interests of
the Company and the Company's stockholders in the event the Company was
involved in an extraordinary transaction involving the possible sale or other
disposition of all or a significant portion of the Company. These types of
extraordinary transactions can be distracting and create significant personal
uncertainties and risks, and can disrupt the availability of continued service
from executives and key employees. As a result, the Company has entered into
change of control employment agreements with each of the Named Executives and
with the other key employees included in the LTIP.

   The change of control employment agreements provide for severance benefits
only if both (1) a Change of Control (as defined in the change of control
employment agreement) of the Company occurs and (2) the executive's employment
is terminated under certain circumstances set forth in the change of control
employment agreement. The purchase of Shares pursuant to the Offer will be a
Change of Control for purposes of these change of control employment
agreements. These change of control employment agreements have three-year
terms, which terms extend for one year upon each anniversary unless a notice
not to extend is given by the Company. If a Change of Control occurs during the
term of a change of control employment agreement, then the change of control
employment agreements become operative for a fixed three-year period. The
change of control employment agreements provide generally that the executive's
terms and conditions of employment (including position, location, compensation
and benefits) will not be adversely changed during the three-year period after
a Change of Control. If the Company terminates the executive's employment
(other than for cause, death or disability) or if the executive terminates for
good reason during the three-year period after a Change of Control (or upon
certain terminations prior to a Change of Control or in connection with or in
anticipation of a Change of Control), the executive generally is entitled to
receive the following: (1) three times (a) the executive's annual base salary
plus (b) the executive's annual bonus (as determined in the change of control
employment agreements), (2) unpaid deferred compensation and vacation pay, and
(3) welfare benefits for three years. If the executive terminates employment
for any reason during the 30-day period following the first anniversary of the
Change of Control, the executive generally is entitled to receive the
following: (1) two times (a) the executive's annual base salary plus (b) the
executive's annual bonus (as determined in the change of control employment
agreements), (2) unpaid deferred compensation and vacation pay, and (3) welfare
benefits for two years. In addition, in each case, the executive is entitled to
receive an additional payment, if any, in an amount sufficient to make the
executive whole for any excise tax on excess parachute payments imposed under
Section 4999 of the Internal Revenue Code of 1986, as amended.

   The stock options described above under "Director Compensation--Stock
Compensation" and the options and loans described above under "Compensation of
Executive Officers--Stock Options and Long-Term Incentive Programs" also have
change of control provisions, as described above.

   The execution of the Merger Agreement constitutes a "Change of Control" for
the Company's stock options and loans and consummation of the Offer will
constitute a "Change of Control" under the change of control employment
agreements described above.

Board of Directors
TJ International, Inc.
200 East Mallard Drive
Boise, Idaho 83706

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $1.00
per share (the "Shares"), of TJ International, Inc. (the "Company") of the
$42.00 per Share in cash proposed to be paid by Sub (as defined below) in the
Tender Offer and the Merger (as such terms are defined below) pursuant to the
Agreement and Plan of Merger, dated as of November 23, 1999, among Weyerhaeuser
Company ("Parent"), WTJ, Inc., a wholly-owned subsidiary of Parent ("Sub"), and
the Company (the "Agreement"). The Agreement provides for a tender offer for
all of the Shares (the "Tender Offer") pursuant to which Sub will pay $42.00
per Share in cash for each Share accepted. The Agreement further provides that
following completion of the Tender Offer, Sub will be merged into the Company
(the "Merger") and each outstanding Share, other than Appraisal Shares, as
defined in the Agreement, and other than Shares owned by the Company, Parent or
Sub will be converted into the right to receive $42.00 in cash.

Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, including
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. We are familiar with the Company having provided certain investment
banking services to the Company from time to time, including having acted as
its financial advisor in connection with, and having participated in certain of
the negotiations leading to, the Agreement. We also have provided certain
investment banking services to Parent and MacMillan Bloedel Ltd., which Parent
recently acquired, from time to time, including having acted as co-managing
underwriter of a public offering by Parent in October 1997 of $300 million of
6.95% debentures due in 2027 and may provide investment banking services to
Parent in the future. Goldman, Sachs & Co. provides a full range of financial
advisory and

securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of the Company or Parent for its own account and for the accounts
of customers.

In connection with this opinion, we have reviewed, among other things, the
Agreement; the Partnership Agreement (as defined in the Agreement); Annual
Reports to Stockholders and Annual Reports on Form 10-K of the Company for the
five fiscal years ended January 2, 1999; certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company; certain other
communications from the Company to its stockholders; and certain internal
financial analyses and forecasts for the Company prepared by its management. We
also have held discussions with members of the senior management of the Company
regarding its past and current business operations, financial condition and
future prospects. In addition, we have reviewed the reported price and trading
activity for the Shares, compared certain financial and stock market
information for the Company with similar information for certain other
companies the securities of which are publicly traded, reviewed the financial
terms of certain recent business combinations in the Forest Products and
Building Materials industries specifically and in other industries generally
and performed such other studies and analyses as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us and have assumed such accuracy and
completeness for purposes of rendering this opinion. In addition, we have not
made an independent evaluation or appraisal of the assets and liabilities of
the Company or any of its subsidiaries and we have not been furnished with any
such evaluation or appraisal. We were not requested to solicit, and did not
solicit, interest from other parties with respect to an acquisition of or other
business combinations with the Company. Our advisory services and the opinion
expressed herein are provided for the information and assistance of the Board
of Directors of the Company in connection with its consideration of the
transaction contemplated by the Agreement and such opinion does not constitute
a recommendation as to whether or not any holder of Shares should tender such
Shares in connection with such transaction.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the $42.00 per
Share in cash proposed to be paid by Sub in the Tender Offer and the Merger to
the holders of the Shares is fair from a financial point of view to such
holders.

Very truly yours,

Purchaser and the Company pursuant to which, following the consummation of the
Offer and the satisfaction or waiver of certain conditions, the Purchaser will
be merged with and into the Company (the "Merger"), with the Company surviving
the Merger as a subsidiary of Weyerhaeuser. At the election of Weyerhaeuser,
any direct or indirect subsidiary of Weyerhaeuser may be substituted for the
Purchaser as a constituent corporation in the Merger.

  The Board of Directors of the Company unanimously (i) approved the Merger
Agreement, the Offer and the Merger, (ii) determined that the transactions
contemplated by the Merger Agreement, including each of the Offer and the
Merger, are fair to and in the best interests of the Company and its
stockholders and (iii) recommends that stockholders of the Company accept the
Offer and tender their Shares pursuant to the Offer. The factors considered by
the Board of Directors of the Company in arriving at its decision to approve
the Merger Agreement, the Offer and the Merger and recommending that
stockholders of the Company accept the Offer and tender their Shares pursuant
to the Offer, are described in the Company's Solicitation/Recommendation
Statement on Schedule 14D-9 (the "Schedule 14D-9"), which is being mailed to
stockholders of the Company together with this Offer to Purchase.

  Goldman, Sachs & Co. ("Goldman Sachs") has acted as the Company's financial
advisor. Goldman Sachs delivered its written opinion to the Board of Directors
of the Company that, as of November 23, 1999, the $42.00 per share proposed to
be paid by the Purchaser in the Offer and the Merger to the holders of Common
Shares was fair from a financial point of view to such holders. The entire
text of the opinion, which sets forth assumptions made, matters considered and
limitations in connection with the opinion is attached as Annex B to the
Schedule 14D-9 mailed to stockholders. The opinion of Goldman Sachs referred
to herein does not constitute a recommendation as to whether or not any holder
of Shares should tender such Shares in connection with the Offer. Stockholders
are urged to, and should, read such opinion carefully in its entirety.

                                       1

  The Offer is conditioned upon, among other things, (1) there being validly
tendered and not withdrawn prior to the Expiration Date (as defined in Section
1) that number of Shares that would represent at least 50.1% of the Fully
Diluted Shares (as defined in Section 14) on the date of purchase (the
"Minimum Condition"), and (2) any waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), applicable to
the purchase of Shares pursuant to the Offer shall have expired or been
terminated. See Sections 1, 12 and 14.

  In the Merger, each issued Share (other than Shares owned by Weyerhaeuser,
the Purchaser or the Company or any wholly owned subsidiary of Weyerhaeuser,
the Purchaser or the Company or by stockholders, if any, who are entitled to
and properly exercise appraisal rights under Delaware law) will be converted
into an amount in cash equal to the Offer Price, without interest thereon.
Consummation of the Merger is subject to a number of conditions, including
approval by stockholders of the Company if such approval is required under
applicable law. In order to consummate the Merger without the approval of
stockholders of the Company, Weyerhaeuser and the Purchaser will need to own
at least 90% of the outstanding Common Shares and 90% of the outstanding
Preferred Shares. Section 12 more fully describes the requirements for
consummating a merger under Delaware law and the terms of the Merger
Agreement.

  The Company has informed the Purchaser that, as of November 17, 1999, there
were 18,351,054 Common Shares and 1,097,719 Preferred Shares issued and
outstanding and 1,671,436 Common Shares reserved for issuance upon the
exercise of outstanding options or other rights to purchase Shares from the
Company. Based upon the foregoing and assuming that no Shares are otherwise
issued after November 17, 1999 (except upon the exercise of such options or
the conversion of the Preferred Shares), there will be 21,120,209 Fully
Diluted Shares outstanding and the Minimum Condition will be satisfied if at
least 10,771,306 Shares are validly tendered and not withdrawn prior to the
Expiration Date. The actual number of Shares required to be tendered to
satisfy the Minimum Condition will depend upon the actual number of Fully
Diluted Shares outstanding on the date that the Purchaser accepts Shares for
payment pursuant to the Offer. If the Minimum Condition is satisfied and the
Purchaser accepts for payment Shares tendered pursuant to the Offer, the
Purchaser will be able to elect a majority of the members of the Company's
Board of Directors and to effect the Merger without the affirmative vote of
any other stockholder of the Company. See Section 12.

  Certain U.S. federal income tax consequences of the sale of Shares pursuant
to the Offer and the conversion of Shares pursuant to the Merger are described
in Section 5.

  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION THAT SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

                               THE TENDER OFFER

1. Terms of the Offer

  Upon the terms and subject to the conditions of the Offer, the Purchaser
will accept for payment and pay for all Shares validly tendered prior to the
Expiration Date and not theretofore withdrawn in accordance with Section 3.
The term "Expiration Date" means 8:00 p.m., New York City time, on Wednesday,
January 5, 2000, unless and until the Purchaser shall have extended the period
of time during which the Offer is open, in which event the term "Expiration
Date" shall mean the latest time and date on which the Offer, as so extended
by the Purchaser, will expire.

  In the Merger Agreement, the Purchaser has agreed that, except as described
below, it will not, without the consent of the Company, (a) reduce the number
of Shares subject to the Offer, (b) reduce the Offer Price, (c) modify or add
to the conditions to the Offer (which are set forth in Section 14), (d) extend
the Offer, (e) change the form of consideration payable in the Offer or (f)
otherwise amend the Offer in any manner materially adverse to the holders of
Shares. However, the Merger Agreement provides that, without the consent of
the Company, the Purchaser may (i) extend the Offer, if, at the Expiration
Date, any of the conditions to the Purchaser's obligation to purchase Shares
are not satisfied, until such time as such conditions are satisfied or waived,
(ii) extend the Offer for any period required by any rule, regulation,
interpretation or position of the Commission or the staff thereof applicable
to the Offer and (iii) extend the Offer for any term for a period (a
"Weyerhaeuser Extension Period") of not more than ten business days beyond the
latest expiration date that would otherwise be permitted or required under the
terms of the Merger Agreement; provided, however, that if the Purchaser
extends the Offer pursuant to clause (iii) of this sentence, it must waive
during any such Weyerhaeuser Extension Period all conditions of the Offer set
forth in Section 14 other than (x) the Minimum Condition and (y) the condition
in paragraph (b) of Section 14 solely to the extent Weyerhaeuser and the
Purchaser would otherwise violate any law in purchasing Common Shares pursuant
to the Offer. If any of the conditions of the Offer set forth in Section 14
(other than the Minimum Condition) is not satisfied or waived on the
Expiration Date of the Offer, then, if requested by the Company, the Purchaser
must extend the Offer one or more times (the period of each such extension to
be determined by the Purchaser) for up to 30 days in the aggregate for all
such extensions, provided that at the time of such extension any such
condition is reasonably capable of being satisfied. As used in this Offer to
Purchase, "business day" has the meaning set forth in Rule 14d-1 under the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

  Subject to the Merger Agreement (which, as described above, prohibits
certain amendments to the Offer without the consent of the Company) and the
applicable rules and regulations of the Commission, the Purchaser reserves the
right (but is not obligated except as described below), at any time and from
time to time, and regardless of whether or not any of the events or facts set
forth in Section 14 have occurred, (a) to extend the period of time during
which the Offer is open, and thereby delay acceptance for payment of and the
payment for any Shares, by giving oral or written notice of such extension to
the Depositary and (b) to amend the Offer in any other respect by giving oral
or written notice of such amendment to the Depositary. Under no circumstances
will interest be paid on the purchase price for tendered Shares, whether or
not the Purchaser exercises its right to extend the Offer.

  If by 8:00 p.m., New York City time, on Wednesday, January 5, 2000 (or any
date or time then set as the Expiration Date), any of or all the conditions to
the Offer have not been satisfied or waived, the Purchaser reserves the right
(but is not obligated except as described below), subject to the Merger
Agreement and to the applicable rules and regulations of the Commission, (a)
to terminate the Offer and not accept for payment or pay for any Shares and
return all tendered Shares to tendering stockholders, (b) to waive all the
unsatisfied conditions and accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn, (c) to
extend the Offer and, subject to the right of stockholders to withdraw Shares
until the Expiration Date, retain the Shares that have been tendered during
the period or periods for which the Offer is extended or (d) to amend the
Offer.

                                       3
<PAGE>

  Any extension, waiver, amendment or termination will be followed as promptly
as practicable by public announcement thereof. In the case of an extension,
Rule 14e-l(d) under the Exchange Act requires that the announcement be issued
no later than 9:00 a.m., New York City time, on the next business day after
the previously scheduled Expiration Date in accordance with the public
announcement requirements of Rule 14d-3(c) under the Exchange Act. Subject to
applicable law (including Rules 14d-4(c) and 14d-6(d) under the Exchange Act,
which require that any material change in the information published, sent or
given to stockholders in connection with the Offer be promptly disseminated to
stockholders in a manner reasonably designed to inform stockholders of such
change) and without limiting the manner in which the Purchaser may choose to
make any public announcement, the Purchaser will not have any obligation to
publish, advertise or otherwise communicate any such public announcement other
than by making a release to the Dow Jones News Service.

  If the Purchaser extends the Offer or if the Purchaser is delayed in its
acceptance for payment of or payment (whether before or after its acceptance
for payment of Shares) for Shares or it is unable to pay for Shares pursuant
to the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer, the Depositary may retain tendered Shares on behalf of the
Purchaser, and such Shares may not be withdrawn except to the extent tendering
stockholders are entitled to withdrawal rights as described in Section 3.
However, the ability of the Purchaser to delay the payment for Shares that the
Purchaser has accepted for payment is limited by Rule 14e-l(c) under the
Exchange Act, which requires that a bidder pay the consideration offered or
return the securities deposited by or on behalf of holders of securities
promptly after the termination or withdrawal of such bidder's offer, and by
the terms of the Merger Agreement, which require that the Purchaser pay for
Shares accepted for payment as soon as practicable after the Expiration Date.

  If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials and extend
the Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1(b) and
(d) under the Exchange Act. The minimum period during which an offer must
remain open following material changes in the terms of such offer or
information concerning such offer, other than a change in price or a change in
the percentage of securities sought, will depend upon the facts and
circumstances then existing, including the relative materiality of the changed
terms or information. With respect to a change in price or a change in the
percentage of securities sought, under Rule 14e-1(b) a minimum period of ten
business days is generally required to allow for adequate dissemination to
stockholders.

  The Company has provided the Purchaser with the Company's stockholder lists
and security position listings for the purpose of disseminating the Offer to
holders of Shares. This Offer to Purchase, the related Letter of Transmittal
and other relevant materials will be mailed by the Purchaser to record holders
of Shares, and will be furnished to brokers, dealers, banks, trust companies
and similar persons whose names, or the names of whose nominees, appear on the
stockholder lists, or, if applicable, who are listed as participants in a
clearing agency's security position listing, for subsequent transmittal to
beneficial owners of Shares.

2. Procedure for Tendering Shares

  Valid Tender. For a stockholder validly to tender Shares pursuant to the
Offer, either (a) a Letter of Transmittal (or a facsimile thereof), properly
completed and duly executed, together with any required signature guarantees,
or, in the case of a book-entry transfer, an Agent's Message (as defined
below), and any other required documents, must be received by the Depositary
at one of its addresses set forth on the back cover of this Offer to Purchase
prior to the Expiration Date and either certificates for tendered Shares must
be received by the Depositary at one of such addresses or such Shares must be
delivered pursuant to the procedures for book-entry transfer set forth below
(and a Book-Entry Confirmation (as defined below) received by the Depositary),
in each case prior to the Expiration Date, or (b) the tendering stockholder
must comply with the guaranteed delivery procedures described below.

                                       4
<PAGE>

  Book-Entry Transfer. The Depositary will establish an account with respect
to the Shares at The Depository Trust Company (the "Book-Entry Transfer
Facility") for purposes of the Offer within two business days after the date
of this Offer to Purchase. Any financial institution that is a participant in
the Book-Entry Transfer Facility's system may make book-entry delivery of
Shares by causing the Book-Entry Transfer Facility to transfer such Shares
into the Depositary's account in accordance with the Book-Entry Transfer
Facility's procedures for such transfer. However, although delivery of Shares
may be effected through book-entry transfer into the Depositary's account at
the Book-Entry Transfer Facility, the Letter of Transmittal (or a facsimile
thereof), properly completed and duly executed, with any required signature
guarantees, or an Agent's Message, and any other required documents, must, in
any case, be transmitted to, and received by, the Depositary at one of its
addresses set forth on the back cover of this Offer to Purchase prior to the
Expiration Date, or the tendering stockholder must comply with the guaranteed
delivery procedures described below. The confirmation of a book-entry transfer
of Shares into the Depositary's account at the Book-Entry Transfer Facility as
described above is referred to herein as a "Book-Entry Confirmation". Delivery
of documents to the Book-Entry Transfer Facility in accordance with the Book-
Entry Transfer Facility's procedures does not constitute delivery to the
Depositary.

  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

  The method of delivery of Shares, the Letter of Transmittal and all other
required documents, including delivery through the Book-Entry Transfer
Facility, is at the election and risk of the tendering stockholder. Shares
will be deemed delivered only when actually received by the Depositary
(including, in the case of a book-entry transfer, by Book-Entry Confirmation).
If delivery is by mail, registered mail with return receipt requested,
properly insured, is recommended. In all cases, sufficient time should be
allowed to ensure timely delivery.

  Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal (a) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section 2, includes any
participant in the Book-Entry Transfer Facility's system whose name appears on
a security position listing as the owner of the Shares) of Shares tendered
therewith and such registered holder has not completed either the box entitled
"Special Delivery Instructions" or the box entitled "Special Payment
Instructions" on the Letter of Transmittal or (b) if such Shares are tendered
for the account of a financial institution (including most commercial banks,
savings and loan associations and brokerage houses) that is a participant in
the Security Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program
(such participant, an "Eligible Institution"). In all other cases, all
signatures on the Letter of Transmittal must be guaranteed by an Eligible
Institution. See Instructions 1 and 5 to the Letter of Transmittal. If the
certificates for Shares are registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made or
certificates for Shares not tendered or not accepted for payment are to be
returned to a person other than the registered holder of the certificates
surrendered, the tendered certificates must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name or names
of the registered holders or owners appear on the certificates, with the
signatures on the certificates or stock powers guaranteed as aforesaid. See
Instructions 1 and 5 to the Letter of Transmittal.

  Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met:

    (i) such tender is made by or through an Eligible Institution;

    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Purchaser, is received
  by the Depositary, as provided below, prior to the Expiration Date; and

                                       5
<PAGE>

    (iii) the certificates for all tendered Shares, in proper form for
  transfer (or a Book-Entry Confirmation with respect to all such Shares),
  together with a Letter of Transmittal (or a facsimile thereof), properly
  completed and duly executed, with any required signature guarantees, or, in
  the case of a book-entry transfer, an Agent's Message, and any other
  required documents are received by the Depositary within three trading days
  after the date of execution of such Notice of Guaranteed Delivery. A
  "trading day" is any day on which the Nasdaq Stock Market ("Nasdaq") is
  open for business.

  The Notice of Guaranteed Delivery may be delivered to the Depositary and
must include a guarantee by an Eligible Institution in the form set forth in
such Notice of Guaranteed Delivery.

  The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering stockholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

  Distribution of Rights. Holders of Common Shares will be required to tender
one Right for each Common Share tendered to effect a valid tender of such
Common Share. Unless and until the Distribution Date (as defined in the Rights
Agreement) occurs, the Rights are represented by and transferred with the
Common Shares. Accordingly, if the Distribution Date does not occur prior to
the Expiration Date of the Offer, a tender of Common Shares will constitute a
tender of the associated Rights. If, however, pursuant to the Rights Agreement
or otherwise, a Distribution Date does occur, certificates representing a
number of Rights equal to the number of Common Shares being tendered must be
delivered to the Depositary in order for such Common Shares to be validly
tendered. If a Distribution Date has occurred, a tender of Common Shares
without Rights constitutes an agreement by the tendering stockholder to
deliver certificates representing a number of Rights equal to the number of
Common Shares tendered pursuant to the Offer to the Depositary within three
trading days after the date such certificates are distributed. The Purchaser
reserves the right to require that it receive such certificates prior to
accepting Common Shares for payment. Payment for Common Shares tendered and
purchased pursuant to the Offer will be made only after timely receipt by the
Depositary of, among other things, such certificates, if such certificates
have been distributed to holders of Common Shares. The Purchaser will not pay
any additional consideration for the Rights tendered pursuant to the Offer.
The Rights Agreement has been amended as of November 23, 1999, to exempt the
Merger Agreement, the Merger and the acquisition of Shares by Weyerhaeuser or
the Purchaser pursuant to the Offer from the provisions of the Rights
Agreement.

  Appointment. By executing a Letter of Transmittal (or a facsimile thereof),
a tendering stockholder will irrevocably appoint designees of the Purchaser as
such stockholder's attorneys-in-fact and proxies in the manner set forth in
the Letter of Transmittal, each with full power of substitution, to the full
extent of such stockholder's rights with respect to the Shares tendered by
such stockholder and accepted for payment by the Purchaser and with respect to
any and all other Shares or other securities or rights issued or issuable in
respect of such Shares on or after November 23, 1999. All such proxies will be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such stockholder as provided herein. Upon such
appointment, all prior powers of attorney, proxies and consents given by such
stockholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given (and, if given, will not be
effective). The designees of the Purchaser will thereby be empowered to
exercise all voting and other rights with respect to such Shares and other
securities or rights in respect of any annual, special or adjourned meeting of
the Company's stockholders, actions by written consent in lieu of any such
meeting or otherwise, as they in their sole discretion deem proper. The
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser must be able to exercise full voting, consent and
other rights with respect to such Shares and other securities or rights,
including voting at any meeting of stockholders.

  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser in its sole discretion, which
determination will be final and binding. The Purchaser reserves the absolute
right to reject any or all tenders

                                       6
<PAGE>

determined by it not to be in proper form or the acceptance for payment of or
payment for which may, in the opinion of the Purchaser's counsel, be unlawful.
The Purchaser also reserves the absolute right to waive any defect or
irregularity in the tender of any Shares of any particular stockholder whether
or not similar defects or irregularities are waived in the case of other
stockholders. No tender of Shares will be deemed to have been validly made
until all defects or irregularities relating thereto have been cured or
waived. None of the Purchaser, Weyerhaeuser, the Company, the Depositary, the
Information Agent, the Dealer Manager or any other person will be under any
duty to give notification of any defects or irregularities in tenders or incur
any liability for failure to give any such notification. The Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter
of Transmittal and the instructions thereto) will be final and binding.

  Backup Withholding. In order to avoid "backup withholding" of U.S. federal
income tax on payments of cash pursuant to the Offer or the Merger, a
stockholder surrendering Shares in the Offer or the Merger must, unless an
exemption applies, provide the Depositary with such stockholder's correct
taxpayer identification number ("TIN") on a Substitute Form W-9 and certify
under penalties of perjury that such TIN is correct and that such stockholder
is not subject to backup withholding. If a stockholder does not provide such
stockholder's correct TIN or fails to provide the certifications described
above, the Internal Revenue Service (the "IRS") may impose a penalty on such
stockholder and payment of cash to such stockholder pursuant to the Offer or
Merger may be subject to backup withholding of 31%. All stockholders
surrendering Shares pursuant to the Offer or the Merger should complete and
sign the main signature form and the Substitute Form W-9 included as part of
the Letter of Transmittal to provide the information and certification
necessary to avoid backup withholding (unless an applicable exemption exists
and is proved in a manner satisfactory to the Purchaser and the Depositary).
Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding.
Noncorporate foreign stockholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, a copy of which may be
obtained from the Depositary, in order to avoid backup withholding. See
Instruction 9 to the Letter of Transmittal.

  Preferred Shares. Preferred Shares may be tendered only by the trustee for
the Company's Investment Plan. Accordingly, holders of beneficial interests in
Preferred Shares who wish to tender such Shares should do so by delivering
appropriate instructions to the trustee.

3. Withdrawal Rights

  Except as otherwise provided in this Section 3, tenders of Shares are
irrevocable. Shares tendered pursuant to the Offer may be withdrawn pursuant
to the procedures set forth below at any time prior to the Expiration Date
and, unless theretofore accepted for payment and paid for by the Purchaser
pursuant to the Offer, may also be withdrawn at any time after January 28,
2000.

  For a withdrawal to be effective, a written notice of withdrawal must be
received by the Depositary at one of its addresses set forth on the back cover
of this Offer to Purchase and must specify the name of the person having
tendered the Shares to be withdrawn, the number of Shares to be withdrawn and
the name of the registered holder of the Shares to be withdrawn, if different
from the name of the person who tendered the Shares. If certificates for
Shares have been delivered or otherwise identified to the Depositary, then,
prior to the physical release of such certificates, the serial numbers shown
on such certificates must be submitted to the Depositary and, unless such
Shares have been tendered by an Eligible Institution, the signatures on the
notice of withdrawal must be guaranteed by an Eligible Institution. If Shares
have been delivered pursuant to the procedures for book-entry transfer
described in Section 2, any notice of withdrawal must also specify the name
and number of the account at the Book-Entry Transfer Facility to be credited
with the withdrawn Shares and otherwise comply with the Book-Entry Transfer
Facility's procedures. Withdrawals of tenders of Shares may not be rescinded,
and any Shares properly withdrawn will thereafter be deemed not validly
tendered for purposes of the Offer. However, withdrawn Shares may be tendered
by again following one of the procedures described in Section 2 at any time
prior to the Expiration Date.

                                       7
<PAGE>

  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Weyerhaeuser, the Company, the Depositary, the Information Agent,
the Dealer Manager or any other person will be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.

4. Acceptance for Payment and Payment

  Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will accept for payment and will pay for all
Shares validly tendered prior to the Expiration Date and not properly
withdrawn in accordance with Section 3 promptly after the Expiration Date. The
Purchaser expressly reserves the right to delay acceptance for payment of or
payment for Shares in order to comply in whole or in part with any applicable
law, including the HSR Act. Any such delays will be effected in compliance
with Rule 14e-l(c) under the Exchange Act (relating to a bidder's obligation
to pay for or return tendered securities promptly after the termination or
withdrawal of such bidder's offer).

  In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (a) certificates
for (or a timely Book-Entry Confirmation with respect to) such Shares, (b) a
Letter of Transmittal (or a facsimile thereof), properly completed and duty
executed, with any required signature guarantees, or, in the case of a book-
entry transfer, an Agent's Message, with respect to such Shares and (c) any
other documents required by the Letter of Transmittal. The per Share
consideration paid to any stockholder pursuant to the Offer will be the
highest per Share consideration paid to any other stockholder pursuant to the
Offer. Accordingly, tendering stockholders may be paid at different times
depending upon when certificates for Shares or Book-Entry Confirmations with
respect to Shares we are actually received by the Depositary.

  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn as, if and when the Purchaser gives oral or written notice to
the Depositary of the Purchaser's acceptance for payment of such Shares.
Payment for Shares accepted for payment pursuant to the Offer will be made by
deposit of the purchase price therefor with the Depositary, which will act as
an agent for tendering stockholders for the purpose of receiving payment from
the Purchaser and transmitting payment to tendering stockholders. Under no
circumstances will interest be paid on the purchase price of the Shares to be
paid by the Purchaser, regardless of any extension of the Offer or any delay
in making such payment.

  If any tendered Shares are not purchased pursuant to the Offer for any
reason, certificates for any such Shares will be returned, without expense to
the tendering stockholder (or, in the case of Shares delivered by book-entry
transfer of such Shares into the Depositary's account at the Book-Entry
Transfer Facility pursuant to the procedures described in Section 2, such
Shares will be confirmed to an account maintained at the Book-Entry Transfer
Facility), as promptly as practicable after the expiration or termination of
the Offer.

  The Purchaser reserves the right to transfer or assign, in whole or from
time to time in part, to Weyerhaeuser, or to one or more direct or indirect
wholly owned subsidiaries of Weyerhaeuser, the right to purchase Shares
tendered pursuant to the Offer, but any such transfer or assignment will not
relieve the Purchaser of its obligations under the Offer and will in no way
prejudice the rights of tendering stockholders to receive payment for Shares
validly tendered and accepted for payment pursuant to the Offer.

5. Certain U.S. Federal Income Tax Consequences

  The receipt of cash pursuant to the Offer or the Merger will be a taxable
transaction for U.S. federal income tax purposes under the Internal Revenue
Code of 1986, as amended (the "Code"), and may also be a taxable transaction
under applicable state, local or foreign income or other tax laws. Generally,
for U.S. federal income

                                       8

tax purposes, a stockholder will recognize gain or loss equal to the
difference between the amount of cash received by the stockholder pursuant to
the Offer or the Merger and the aggregate tax basis in the Shares tendered by
the stockholder and purchased pursuant to the Offer or converted into cash in
the Merger, as the case may be. Gain or loss will be calculated separately for
each block of Shares tendered and purchased pursuant to the Offer or converted
into cash in the Merger, as the case may be.

  If Shares are held by a stockholder as capital assets, gain or loss
recognized by the stockholder will be capital gain or loss, and will be long-
term capital gain or loss if the stockholder's holding period for the Shares
exceeds one year. Certain noncorporate stockholders will be eligible for a
maximum U.S. federal income tax rate of 20% on long-term capital gain. In
addition, the deductibility of capital losses is subject to limitations for
both individuals and corporations.

  A stockholder that tenders or converts Shares may be subject to 31% backup
withholding unless the stockholder provides its TIN and certifies that such
number is correct or properly certifies that it is awaiting a TIN, or unless
an exemption applies. Exemptions are available for stockholders that are
corporations and for certain foreign individuals and entities. A stockholder
that does not furnish a required TIN may be subject to a penalty imposed by
the IRS. See "Backup Withholding" under Section 2.

  If backup withholding applies to a stockholder, the Depositary is required
to withhold 31% from payments to such stockholder. Backup withholding is not
an additional tax. Rather, the amount of the backup withholding can be
credited against the U.S. federal income tax liability of the person subject
to the backup withholding, provided that the required information is given to
the IRS. If backup withholding results in an overpayment of tax, a refund can
be obtained by the stockholder by filing a federal income tax return.

  The foregoing discussion may not be applicable with respect to Shares
received pursuant to the exercise of employee stock options or otherwise as
compensation or with respect to holders of Shares who are subject to special
tax treatment under the Code, such as non-U.S. persons, life insurance
companies, tax-exempt organizations and financial institutions and may not
apply to a holder of Shares in light of its individual circumstances.
Stockholders are urged to consult their own tax advisors to determine the
particular tax consequences to them (including the application and effect of
any state, local or foreign income and other tax laws) of the Offer and the
Merger.

  On November 22, 1999, the last full trading day before the public
announcement of the execution of the Merger Agreement, the last reported sales
price of the Common Shares on the Nasdaq was $32.25 per share. On November 29,
1999, the last full trading day before commencement of the Offer, the last
reported sales price of the Common Shares on the Nasdaq was $41.63 per share.
Stockholders are urged to obtain current market quotations for the Common
Shares.

  All Preferred Shares are held by the trustee under the Company's Investment
Plan for the benefit of participants in such plan and are not publicly traded.
Each Preferred Share is entitled to receive an annual dividend of $1.065, and
no dividends can be paid on Common Shares until all dividends then due and
payable on Preferred Shares have been paid. The Merger Agreement permits the
Company to continue to pay regular quarterly dividends on the Common Shares of
not more than $0.055 per Share and regular annual cash dividends on the
Preferred Shares of not more than $1.065 per share. The payment of dividends
on the Common Shares is a matter for the discretion of the Board of Directors
of the Company and is subject to customary restrictions thereon.

7. Effect of the Offer on the Market for the Common Shares; Share Quotation;
   Exchange Act Registration; Margin Regulations

  Market for the Shares. The purchase of Common Shares pursuant to the Offer
will reduce the number of holders of Common Shares and the number of Common
Shares that might otherwise trade publicly and could adversely affect the
liquidity and market value of the remaining Common Shares held by the public.

  Share Quotation. Depending upon the number of Common Shares purchased
pursuant to the Offer, the Common Shares may no longer meet the requirements
of the Nasdaq for continued listing. According to the Nasdaq's published
guidelines, the Nasdaq would consider delisting the Common Shares if, among
other things, the total number of round-lot stockholders (including both
holders of record and beneficial holders of stock) were to fall below 300, or
the number of publicly held Common Shares (exclusive of management or other
concerned holdings) were to fall below 500,000 or the aggregate market value
of publicly held Common Shares were to not

                                      10
<PAGE>

exceed $1 million. According to the Company, as of November 24, 1999, there
were approximately 1,712 holders of record of Common Shares and there were
18,351,048 Common Shares outstanding. If, as a result of the purchase of
Common Shares pursuant to the Offer or otherwise, the Common Shares no longer
meet the requirements of the Nasdaq for continued listing and the Common
Shares are no longer listed, the market for Common Shares would be adversely
affected.

  If the Nasdaq were to delist the Common Shares, it is possible that the
Common Shares would continue to trade on other securities exchanges or in the
over-the-counter market and that price quotations would be reported by such
exchanges or through other sources. The extent of the public market for the
Common Shares and the availability of such quotations would, however, depend
upon the number of holders of Common Shares remaining at such time, the
interests in maintaining a market in Common Shares on the part of securities
firms, the possible termination of registration of the Common Shares under the
Exchange Act, as described below, and other factors.

  Exchange Act Registration. The Common Shares are currently registered under
the Exchange Act. Registration of the Common Shares under the Exchange Act may
be terminated upon application of the Company to the Commission if the Common
Shares are neither listed on a national securities exchange nor held by 300 or
more holders of record. Termination of registration of the Common Shares under
the Exchange Act would substantially reduce the information required to be
furnished by the Company to its stockholders and to the Commission and would
make certain provisions of the Exchange Act no longer applicable to the
Company, such as the short-swing profit recovery provisions of Section 16(b)
of the Exchange Act, the requirement of furnishing a proxy statement pursuant
to Section 14(a) of the Exchange Act in connection with stockholders' meetings
and the related requirement of furnishing an annual report to stockholders and
the requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions. Furthermore, the ability of "affiliates" of the Company
and persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or 144A promulgated under the Securities Act
of 1933, may be impaired or eliminated. The Purchaser intends to seek to cause
the Company to apply for termination of registration of the Common Shares
under the Exchange Act as soon after the completion of the Offer as the
requirements for such termination are met.

  If registration of the Common Shares is not terminated prior to the Merger,
then the Common Shares will be delisted from all stock exchanges and the
registration of the Common Shares under the Exchange Act will be terminated
following the consummation of the Merger.

  Margin Regulations. The Common Shares are currently "margin securities"
under the regulations of the Board of Governors of the Federal Reserve System
(the "Federal Reserve Board"), which has the effect, among other things, of
allowing brokers to extend credit on the collateral of the Common Share.
Depending upon factors similar to those described above regarding listing and
market quotations, it is possible that, following the Offer, the Common Shares
would no longer constitute "margin securities" for the purposes of the margin
regulations of the Federal Reserve Board and therefore could no longer be used
as collateral for loans made by brokers.

  Certain Forecast Information. During the course of due diligence discussions
between representatives of Weyerhaeuser and the Company that were conducted
after Weyerhaeuser had made its proposal of $42 per share, the Company
provided Weyerhaeuser or its representatives with certain non-public business
and financial information about the Company. The following is a summary of
certain selected projected financial information provided by the Company (the
"Projections"). The Company advised Weyerhaeuser that in preparing the
Projections, the Company assumed, among other matters, (1) that the housing
market would continue to be strong, with only mild declines in housing starts
through 2001 with a significant recession assumed beginning in 2002, and
recovery beginning in 2003; (2) that engineered lumber products would continue
to replace regular lumber products and increase market penetration; (3) that
the Company would continue its value-added marketing strategy; (4) a reduction
of prices of raw materials (primarily oriented strand board and veneer) due to
reduced demand as residential construction activity slows, with a more
significant decline in 2002 due to the assumed recession; (5) a continuation
of the trend in the reduction of manufacturing costs in new technology plants,
combined with continued growth in acceptance of the Company's new technology
products; (6) the leveraging of the Company's sales, general and
administrative expenses over an increasing sales base, thus reducing those
expenses as a percentage of sales; and (7) capital expenditures estimated to
average approximately $90 million per year over the four-year period
represented by the Projections.

The Company has advised the Purchaser and Weyerhaeuser that it does not as a
matter of course make public any projections as to future performance or
earnings, and the Projections are included in this Offer to Purchase only
because the information was provided to Weyerhaeuser. The Projections have not
been adjusted to reflect the effects of the Offer or the Merger including,
without limitation, the effect of the announcement of execution of the Merger
Agreement on existing and future collaborations of the Company. The
Projections should be read together with the other information contained in
this Section 8.

  The Projections were prepared by the Company and were not prepared with a
view to public disclosure or compliance with the published guidelines of the
SEC or the guidelines established by the American Institute of Certified
Public Accountants regarding projections or forecasts. These forward-looking
statements are subject to certain risks and uncertainties that could cause
actual results to differ materially from the Projections. The Projections
reflect numerous assumptions (not all of which were stated in the Projections
and not all of which were provided to Weyerhaeuser), all made by management of
the Company, with respect to industry performance, general business, economic,
market and financial conditions and other matters, all of which are difficult
to predict, many of which are beyond the Company's control and none of which
were subject to approval by Weyerhaeuser or the Purchaser. Accordingly, there
can be no assurance that the assumptions made in preparing the Projections
will prove accurate, and actual results may be materially greater or less than
those contained in the Projections. The inclusion of the Projections herein
should not be regarded as an indication that any of Weyerhaeuser, the
Purchaser or their respective representatives considered or consider the
Projections to be a reliable prediction of future events, and the Projections
should not be relied upon as such. None of Weyerhaeuser, the Purchaser or
their respective representatives assumes any responsibility for the validity,
reasonableness, accuracy or completeness of the Projections. None of
Weyerhaeuser, the Purchaser or any of their representatives has made, or
makes, any representation to any person regarding the information contained in
the Projections, and none of them intends to update or otherwise revise the
Projections to reflect circumstances existing after the date when made or to
reflect the occurrence of future events even in the event that any or all of
the assumptions underlying the Projections are shown to be in error.

  Available Information. The Company is subject to the informational
requirements of the Exchange Act and, in accordance therewith, is required to
file reports relating to its business, financial condition and other matters.
Information as of particular dates concerning the Company's directors and
officers, their remuneration, stock options and other matters, the principal
holders of the Company's securities and any material interest of such persons
in transactions with the Company is required to be disclosed in the Company's
proxy statements distributed to the Company's stockholders and filed with the
Commission. Such information should be available for inspection at the public
reference facilities of the Commission at 450 Fifth Street, N.W., Washington,
DC 20549, and at the regional offices of the Commission located at Seven World
Trade Center, 13th Floor. New York, NY 10048 and Citicorp Center, 500 West
Madison Street (Suite 1400), Chicago, IL 60661. Copies of such information
should be obtainable, by mail, upon payment of the Commission's customary
charges, by writing to the Commission's principal office at 450 Fifth Street,
N.W., Washington, DC 20549. The Commission maintains a Web site that contains
reports, proxy and information statements and other information regarding
registrants that date file electronically with the Commission. Such reports,
proxy and information statements and other information may be found on the
Commission's Web site address, http://www.sec.gov.

  Except as otherwise stated in this Offer to Purchase, the information
concerning the Company contained herein has been taken from or based upon
publicly available documents on file with the Commission and other publicly
available information. Although the Purchaser and Weyerhaeuser do not have any
knowledge that any such information is untrue, neither the Purchaser nor
Weyerhaeuser takes any responsibility for the accuracy or completeness of such
information or for any failure by the Company to disclose events that may have
occurred and may affect the significance or accuracy of any such information.

9. Certain Information Concerning the Purchaser and Weyerhaeuser

  The Purchaser, a Delaware corporation that is a wholly owned subsidiary of
Weyerhaeuser, was organized to acquire the Company and has not conducted any
unrelated activities since its organization. The principal office

                                      13
<PAGE>

of the Purchaser is located at the principal office of Weyerhaeuser. All
outstanding shares of capital stock of the Purchaser are owned by
Weyerhaeuser.

  Weyerhaeuser is a Washington corporation with its principal office located
at 33663 Weyerhaeuser Way South, Federal Way, Washington 98003. Weyerhaeuser
is one of the largest integrated forest products companies, engaged in the
growing and harvesting of timber and the manufacture, distribution and sale of
forest products, real estate development and construction and other real
estate activities.

  Available Information. Weyerhaeuser is subject to the informational
requirements of the Exchange Act and, in accordance therewith, files reports
relating to its business, financial condition and other matters. Information,
as of particular dates, concerning Weyerhaeuser's directors and officers,
their remuneration, stock options and other matters, the principal holders of
Weyerhaeuser's securities and any material interest of such persons in
transactions with Weyerhaeuser is required to be disclosed in proxy statements
distributed to Weyerhaeuser's stockholders and filed with the Commission. Such
reports, proxy statements and other information should be available for
inspection at the Commission and copies thereof should be obtainable from the
Commission in the same manner as is set forth with respect to the Company in
Section 8.

10. Source and Amount of Funds

  The Purchaser estimates that the total amount of funds required to purchase
pursuant to the Offer the number of Shares that are outstanding on a fully
diluted basis and to pay fees and expenses related to the Offer and the Merger
will be approximately $780 million. The Purchaser plans to obtain all funds
needed for the Offer and the Merger through a capital contribution or loan
from Weyerhaeuser. Weyerhaeuser intends to fund this capital contribution or
loan from existing cash on hand.

11. Contacts and Transactions with the Company; Background of the Offer

  Background of the Offer. On June 20, 1999, Weyerhaeuser, an indirect wholly
owned subsidiary of Weyerhaeuser and MacMillan Bloedel Limited ("MB") entered
into a merger agreement (the "MB Agreement") providing for a plan of
arrangement under Canadian law involving MB in which MB would become an
indirect wholly owned subsidiary of Weyerhaeuser (the "MB Transaction"). The
MB Transaction was consummated on November 1, 1999. MB is now an indirect,
wholly-owned subsidiary of Weyerhaeuser named Weyerhaeuser Company Limited
("WCL").

  MacMillan Bloedel America Inc. ("MBA"), a wholly owned subsidiary of MB,
holds a 49% limited partnership interest in the Partnership. The Company holds
a 51% interest in the Partnership and is the general and managing partner of
the Partnership. See Section 8 and Section 12--"Partnership Agreement".
Weyerhaeuser is a principal supplier of material and products to, and
Weyerhaeuser and WCL are principal distributors of products produced by, the
Partnership. See "Transactions with the Company" below.

  On June 11, 1999, Mr. William R. Corbin, Executive Vice President of
Weyerhaeuser, and Mr. Keith Purchase, Executive Vice President and Chief
Operating Officer of MB, met with Mr. Thomas H. Denig, President and Chief
Executive Officer of the Company, to inform him of the anticipated MB
Transaction. At this meeting, Mr. Purchase proposed that the Company waive any
right that it might have to purchase MBA's 49% partnership interest as a
result of the MB Transaction.

  On June 13 and June 14, 1999, Mr. Steven R. Rogel, President and Chief
Executive Officer of Weyerhaeuser, and Mr. Denig discussed the anticipated MB
Transaction and its potential impact on the Partnership. Mr. Denig stated that
the Company had retained financial and legal advisors to assist the Company in
analyzing its options in light of the proposed MB Transaction. Mr. Rogel
stated that Weyerhaeuser did not believe that the consummation of the MB
Transaction would give rise to any rights of the Company under the Partnership
Agreement. Mr. Denig, however, stated that the Company believed that the MB
Transaction would give the Company the rights provided in the Partnership
Agreement upon a change of control of a partner,

                                      14
<PAGE>

including the right to purchase MBA's interest in the Partnership. See Section
12--"Partnership Agreement". Messrs. Rogel and Denig agreed that they should
meet with other senior officers of each of their respective companies to
discuss the future of the Partnership after the MB Transaction. Mr. Denig
suggested that the two companies enter into a confidentiality and standstill
agreement before discussing the various options that might be available and
sent a form of agreement to Mr. Rogel on June 14, 1999. This confidentiality
and standstill agreement was never executed by Weyerhaeuser.

  Following the June 14 telephone conversation between Messrs. Rogel and
Denig, there were conversations between Goldman Sachs, the Company's financial
advisor, and Morgan Stanley & Co. ("Morgan Stanley"), Weyerhaeuser's financial
advisor, regarding these matters.

  Messrs. Rogel and Denig spoke again by telephone on June 17, 1999, regarding
the conversations between the financial advisors to the two companies and the
confidentiality and standstill agreement proposed by the Company. Mr. Rogel
stated that Weyerhaeuser was not willing to enter into such an agreement. Mr.
Denig stated that, after consulting with members of the Board of Directors of
the Company, he did not believe that consolidation with Weyerhaeuser was the
Company's preferred alternative, but that he would take any compelling offer
by Weyerhaeuser to acquire the Company to the Company's Board of Directors for
consideration. In addition, Mr. Denig indicated that absent such a
transaction, the Company would determine what alternatives to pursue under the
Partnership Agreement (as defined below).

  On June 21, 1999, following execution of the MB Agreement the MB Transaction
was publicly announced.

  On July 7, 1999, Messrs. Rogel and Denig met in Seattle, Washington, with
Mr. Corbin and Mr. Jody B. Olson, Vice President of the Company, to discuss
the future of the Partnership, strategies for growth of the Partnership's
business and the future relationships between the Company and Weyerhaeuser and
MB. Mr. Denig stated that although the Company was still reviewing its options
and no decision had been reached, in his view there were three viable
alternatives: the Company would purchase MBA's 49% partnership interest,
Weyerhaeuser would acquire the Company or MBA would significantly reduce its
interest in the Partnership and relinquish certain rights under the
Partnership Agreement.

  On July 22, 1999, Messrs. Rogel, Denig and Olson and Mr. William C. Stivers,
Executive Vice President and Chief Financial Officer of Weyerhaeuser, met in
Seattle. The Weyerhaeuser representatives stated that an acquisition of the
Company was Weyerhaeuser's strongly preferred alternative and indicated that
Weyerhaeuser was considering a purchase price for the Shares in the mid-$30's
range. The Weyerhaeuser representatives indicated that although Weyerhaeuser
preferred a cash transaction, it would be willing to consider a tax-deferred
transaction with the Company involving Weyerhaeuser stock. At this meeting, in
addition to discussing other alternatives, Messrs. Denig and Olson proposed a
structure in which the Company would acquire MBA's Partnership interest on a
tax-advantaged basis. Subsequently Morgan Stanley informed Goldman Sachs that
Weyerhaeuser had no interest in such a transaction.

  On September 3, 1999, Messrs. Rogel and Corbin met with Messrs. Denig and
Olson in Boise, Idaho. Mr. Rogel stated that Weyerhaeuser did not agree with
the Company's assessment of alternatives available to the parties and stated
that continuation of the Partnership in its current form also should be
considered. They again stated that Weyerhaeuser did not agree that the Company
would have an option to purchase MBA's Partnership interest as a result of the
MB Transaction. Mr. Rogel emphasized the strategic importance to Weyerhaeuser
of the engineered wood products business and stated that Weyerhaeuser would be
prepared to offer $36 per Share to acquire all the outstanding Shares of the
Company. Mr. Denig stated that he did not view that offer as compelling
compared to the other alternatives he believed were available to the Company
and suggested that the respective financial advisors to the two companies meet
to discuss the business and operational assumptions underlying their
respective valuations of the Company. Mr. Denig also indicated that the
Company would continue to work on the alternative of exercising its rights
under the Partnership Agreement to acquire MBA's interest in the Partnership,
but that he did not believe that the continuation of the Partnership in its
then current

                                      15
<PAGE>

form following consummation of the MB Transaction would be an acceptable
alternative for the Company and its stockholders given Weyerhaeuser's
potential influence on the Company in such a circumstance.

  On September 21 and October 1, 1999, the financial advisors to the Company
and Weyerhaeuser met to discuss their respective views on valuation. During
this period, Goldman Sachs advised Morgan Stanley that the Company did not
intend to pursue a transaction of $36 per Share in light of its other
alternatives. On October 11, 1999, Morgan Stanley advised Goldman Sachs that
Weyerhaeuser did not intend to discuss any changes in its proposal to acquire
the Company until it received the Company's view as to an appropriate
acquisition price. Morgan Stanley further stated that Weyerhaeuser wished to
wait until after the MB Transaction was consummated to pursue further
discussions with the Company. In a telephone conversation with Mr. Denig on
October 19, 1999, Mr. Rogel reiterated these statements.

  The MB Transaction was consummated on November 1, 1999. That evening,
Messrs. Rogel, Stivers and Corbin met with Messrs. Denig and Olson and Ms.
Valerie A. Heusinkveld, Vice President and Chief Financial Officer of the
Company, in Seattle, Washington. At this meeting the Company representatives
discussed certain of the assumptions underlying Weyerhaeuser's $36 per Share
proposal. The Company representatives presented reasons why they believed a
higher price was justified for the Shares. At the end of this meeting, Messrs.
Rogel and Denig met separately and Mr. Rogel proposed a $40 per Share price to
acquire the Company. Mr. Denig indicated that he would not be willing to
support such a proposal.

  On November 3, 1999, Mr. Denig invited Mr. Rogel to visit the Company's
Deerwood, Minnesota, facility the following weekend. On November 7, 1999,
during the visit to the Deerwood facility, Messrs. Rogel and Denig again
discussed the acquisition of the Company by Weyerhaeuser, and Mr. Denig
indicated that he might be prepared to support a transaction at $43 per Share.
Mr. Rogel indicated that Weyerhaeuser was not prepared to raise its price
above $40 per Share although Weyerhaeuser would be willing to consider using
consideration consisting of 50% Weyerhaeuser stock. Mr. Denig indicated that
the Company's Board of Directors would meet on November 11 and that he would
inform the Board of Directors of his most recent discussions with Mr. Rogel.

  On November 10, 1999, Mr. Rogel sent the following letter to Mr. Denig:

  "November 10, 1999

  Mr. Tom Denig
  TJ International
  200 East Mallard Drive
  Boise, Idaho 83706

  Dear Tom:

    Following our recent discussions regarding the combination of TJ
  International (TJI) and Weyerhaeuser Company (Weyerhaeuser), I wanted to
  reemphasize, on behalf of Weyerhaeuser and its board of directors, our
  strong interest in pursuing a transaction between our two companies. We
  believe that the combination of our companies is mutually beneficial for
  all of our shareholders. As we discussed, in order to avoid any
  miscommunication, I felt it important to commit to paper the proposal we
  are making.

    After carefully considering all of the information discussed in our
  various meetings and taking into account all of the potential synergies and
  operating improvements that are realistically achievable, we propose to
  purchase TJI for cash at a price of $40.00 for each share of TJI common
  stock. Alternatively, as you have indicated a preference for a stock
  component, we also would consider a transaction with one-half of the
  consideration in cash and one-half in Weyerhaeuser common stock. This
  alternative transaction would be structured as a cash tender at $40.00 for
  half of the outstanding TJI common stock followed by a second step merger
  of 0.6375 shares of Weyerhaeuser common stock for each remaining share of
  TJI common stock, based on Weyerhaeuser's closing price yesterday of
  $62.75. This proposal assumes there are approximately 18.3 million shares
  of TJI common stock outstanding on a fully diluted basis.

                                      16
<PAGE>

    We believe this offer creates superior value for your shareholders versus
  other options available to TJI. This significant premium we are offering
  represents an up-front payment to your shareholders for the synergies and
  operating improvements we expect to achieve. Our proposal represents a 30%
  premium to the closing price of TJI common stock on November 9, 1999, and a
  50% premium to TJI's stock price before the announcement of our merger with
  MacMillan Bloedel. In addition our offer represents substantial premiums of
  50%, 52% and 81% to TJI's 1-, 2- and 5-year average stock prices,
  respectively, as well as a meaningful premium to the long-term price
  targets of research analysts who cover TJI. In addition to the premium, if
  a component of Weyerhaeuser common stock is included, TJI shareholders
  would have a tax-deferred transaction on the stock received, a currency
  with significant liquidity, and an enhanced dividend with pickup of more
  than 130%. TJI shareholders who choose to receive common stock will also
  benefit from the substantial upside in Weyerhaeuser common stock as we
  realize benefits from the pulp and paper cycle as well as the benefits from
  our recent merger with MacMillan Bloedel and a combination with TJI.

    In analyzing your business, we have adopted an aggressive view of the
  future prospects for engineered wood products and TJI's position in the
  market. We have projected operating parameters that exceed TJI's historical
  performance. Given the strategic alliance between Weyerhaeuser and TJI
  signed in 1993 and the close working relationship between our two
  companies, we believe we have fully accounted for all potential synergies.
  Furthermore, now that we have completed our transaction with MacMillan
  Bloedel, Weyerhaeuser is responsible for distributing and providing in-
  market support for products generating over 60% of your revenues, a system
  that would be time consuming and difficult to replicate. For these and
  other reasons, we are convinced that a combination of TJI and Weyerhaeuser
  will generate the highest value for TJI shareholders relative to any other
  alternative.

    As we indicated in recent meetings, and you and I discussed this past
  Monday, this price reflects our full valuation of TJI and is not
  negotiable. We are willing to proceed at this price only if we can achieve
  a prompt, negotiated transaction. We are prepared to negotiate a definitive
  merger agreement with you and to commence a tender offer quickly. To that
  end we are in position to promptly deliver the merger agreement once we
  hear back affirmatively from you after your board meeting. We could
  concurrently commence our confirmatory due diligence process which we
  expect could be completed within one week with your full cooperation. As
  part of the agreement, we will require the strong and full commitment of
  insiders to this transaction, customary no-shop provisions and a break-up
  fee of $30 million. We anticipate the transaction will be subject only to
  customary closing conditions, including regulatory approvals and
  clearances.

    Given the significance to TJI of our proposal, the premium to TJI's
  recent and historical trading prices and the strategic alternatives
  available to TJI, we expect that our proposal will be carefully considered
  by the TJI board.

    We look forward to hearing from you shortly.

                                          Very truly yours,

                                          Steven R. Rogel
                                          Chairman, President & CEO"

  On November 11, 1999, following a meeting of the Company's Board of
Directors, Mr. Rogel received a call from Mr. Dan Nelson and Mr. J. L. Scott,
two directors of the Company. They indicated that if Weyerhaeuser were
prepared to increase the price in its proposal to $42 per Share, in their
view, the Company's Board would support a transaction at $42 per Share. These
directors did not discuss any of the other conditions set forth in this
Weyerhaeuser letter of November 10, 1999.

  On November 12, 1999, Mr. Rogel called Mr. Scott to advise him that he would
discuss a price of $42 per Share with the Board of Directors of Weyerhaeuser
on November 15 and that he would be in a position to respond on November 16,
1999. Mr. Rogel stated that any increase by Weyerhaeuser above its proposed
price of $40 per Share would have to be on an all-cash basis.

  On November 15, 1999, the Board of Directors of Weyerhaeuser approved a cash
offer price of $42 per Share.

                                      17
<PAGE>

  On November 16, 1999, Mr. Rogel called Mr. Scott and stated that
Weyerhaeuser was willing to offer $42 per Share in an all-cash transaction
subject to certain other terms. Mr. Rogel then called Mr. Denig and confirmed
Weyerhaeuser's willingness to proceed with a transaction on this basis.

  Later on November 16, 1999, Mr. Rogel sent the following letter to Mr.
Denig:

  "November 16, 1999

  Mr. Tom Denig
  TJ International
  200 East Mallard Drive
  Boise, Idaho 83706

  Dear Tom:

    Following up on my conversation earlier today with Joe Scott, I wanted to
  reemphasize Weyerhaeuser Company's strong interest in pursuing a
  combination with TJ International (TJI). The Weyerhaeuser Company
  (Weyerhaeuser) board has unanimously authorized me to pursue a transaction
  between our two companies and is convinced that the union would further
  strengthen our combined leadership position in the engineered wood products
  market.

    After thorough consideration and based on the terms outlined below, we
  have agreed to meet your price for TJI of $42.00 per share, payable solely
  in cash. As we discussed on the phone this morning, this meets the price
  you provided me to receive strong and unanimous board support for a cash
  transaction on the terms we have proposed. We believe this represents an
  extremely compelling transaction for your shareholders based on its
  substantial premium to TJI's recent and historical share price.

    The transaction would be structured as a cash tender offer for all of the
  outstanding common and preferred shares, followed by a second step merger
  for the remaining shares. In order to move quickly to completion, the
  Weyerhaeuser team is in place and prepared to commence confirmatory due
  diligence immediately. We would expect that with TJI's full cooperation a
  definitive agreement could be signed and announced next Monday as you
  suggested.

    In consideration for increasing our bid to $42.00 per share, Weyerhaeuser
  expects to receive the following terms (all of which are detailed in the
  draft merger agreement):

    .  Strong support from TJI's insiders including shareholder agreements
       locking up insider shares;

    .  A break-up fee of $30 million payable under customary circumstances;

    .  A customary no-shop provision; and

    .  A waiver of any buy/sell rights TJI may have under the Partnership
       Agreement as a result of the MacMillan-Bloedel transaction.

    An important reason why our Board is willing to increase the price to
  $42.00 per share is the ability to complete the tender offer and merger in
  approximately six weeks versus the several month process to complete the
  second step merger if a stockholder vote is required. In order to ensure
  the acquisition of 90% of each class of TJI's stock, the draft merger
  agreement will require a "share top up" provision. In addition, we will
  need to obtain and review a copy of TJI's ESOP Plan, which is not publicly
  available. Furthermore we expect full cooperation from TJI in structuring
  the transaction so that the ESOP and the ESOP convertible preferred stock
  does not limit our ability to use the "short form" merger procedure.

    As soon as we have confirmation from you following your Board meeting
  this morning, we will deliver a draft merger agreement. We believe it is in
  the best interests of both our companies for our discussions to be kept on
  a strictly confidential basis.

                                      18
<PAGE>

    We have been impressed by the strength of the management team and the
  significant steps you have taken to position the company for future growth.
  We are excited about the prospects of acquiring such an outstanding company
  with strong brand and product recognition. I believe a combination of TJI
  and Weyerhaeuser will create the leading engineered wood products company
  in the world.

                                          Very truly yours,

                                          Steven R. Rogel
                                          Chairman, President & CEO"

  Following a meeting of the Company's Board of Directors later that day, Mr.
Denig informed Mr. Rogel that the Company was prepared to proceed with
negotiation of a transaction at $42 per share assuming that the parties could
agree to a mutually acceptable merger agreement.

  Later that evening, Weyerhaeuser and the Company entered into a
confidentiality agreement covering non-public information to be provided to
Weyerhaeuser by the Company on the evening of November 16. This agreement did
not contain any standstill provisions restricting a unilateral offer by
Weyerhaeuser.

  Counsel to Weyerhaeuser provided counsel to the Company with a draft form of
Merger Agreement on November 16, 1999. During the period from November 17
until November 23, 1999, representatives of Weyerhaeuser and the Company and
their respective financial and legal advisors negotiated the terms of the
Merger Agreement, and Weyerhaeuser held meetings in Boise to conduct a due
diligence investigation of the Company. On November 22, 1999, the Board of
Directors of the Company met to approve the Merger Agreement. On November 23,
the Merger Agreement was executed by Weyerhaeuser and the Company, and public
announcement of the Merger Agreement was made prior to the opening of trading
that day.

  Transactions with the Company. The Company holds a 51% partnership interest
in and is the general and managing partner of, the Partnership. MBA, now a
wholly owned subsidiary of Weyerhaeuser, owns the remaining 49% interest in
the Partnership. The Partnership sells engineered lumber products to
Weyerhaeuser and its subsidiaries (including WCL) in the ordinary course of
business and on terms comparable to the Partnership's other customers. Sales
to Weyerhaeuser and its subsidiaries (including WCL) were $418 million in the
nine months ended September 30, 1999, $466 million in 1998, $424 million in
1997, and $357 million in 1996. Accounts receivable from Weyerhaeuser and its
subsidiaries (including WCL) in connection with these transactions were $16.2
million at January 2, 1999, $17.4 million at January 3, 1998 and $16.7 million
at December 28, 1996. A substantial portion of these transactions occurred
pursuant to a strategic alliance between the Partnership and Weyerhaeuser's
Building Materials Distribution Division pursuant to which the Partnership
distributes its engineered wood products through Weyerhaeuser customer service
centers and Weyerhaeuser has agreed not to actively market engineered wood
products in direct competition with the Partnership's products. The
distribution arrangement may be terminated by either party with two years'
written notice.

  Pursuant to supply agreements, the Partnership purchases certain materials
such as oriented strand board from Weyerhaeuser and its subsidiaries on terms
comparable to other customers for such products. The supply agreements may be
terminated by either party with two years' written notice. Purchases by the
Partnership from Weyerhaeuser and its subsidiaries were $35 million in the
nine months ended September 30, 1999, $36 million in 1998, $27 million in
1997, and $32 million in 1996.


  The Partnership makes quarterly cash distributions to its partners for
payment of state and federal income taxes. These included distributions to MBA
of $17.5 million in 1998, $13.4 million in 1997 and $7.96 million in 1996.

  Certain employees who perform services for the Company at facilities
formerly owned by a subsidiary of Weyerhaeuser remain on such subsidiary's
payroll. The Partnership Agreement provides that the Company must reimburse
the Weyerhaeuser subsidiary for actual payroll and related benefit costs
relating to those employees. Payroll reimbursements were $5.9 million for
1998, $5.9 million for 1997, and $5.8 million for 1996. Total

                                      19
<PAGE>

payables to Weyerhaeuser subsidiaries for such services and tax distributions
were $3.8 million at January 2, 1999, $4.6 million at January 3, 1998, and
$2.7 million at December 28, 1996.

  Except as described in this Offer to Purchase (including Schedule I hereto),
none of the Purchaser, Weyerhaeuser or, to the best knowledge of the Purchaser
and Weyerhaeuser, any of the persons listed in Schedule I hereto, or any
associate or majority-owned subsidiary of the Purchaser, Weyerhaeuser or any
of the persons so listed, beneficially owns any equity security of the
Company, and none of the Purchaser, Weyerhaeuser or, to the best knowledge of
the Purchaser and Weyerhaeuser, any of the other persons referred to above,
has effected any transaction in any equity security of the Company during the
past 60 days. The Purchaser and Weyerhaeuser disclaim beneficial ownership of
any shares owned by any pension plan of Weyerhaeuser or any affiliate of
Weyerhaeuser.

  Except as described in this Offer to Purchase, as of the date hereof (a)
there have not been any contacts, transactions or negotiations between the
Purchaser or Weyerhaeuser, any of their respective subsidiaries or, to the
best knowledge of the Purchaser, any of the persons listed in Schedule I
hereto, on the one hand, and the Company or any of its directors, officers or
affiliates, on the other hand, that are required to be disclosed pursuant to
the rules and regulations of the Commission and (b) none of the Purchaser,
Weyerhaeuser or, to the best knowledge of the Purchaser and Weyerhaeuser, any
of the person listed in Schedule I hereto has any contract, arrangement,
understanding or relationship with any person with respect to any securities
of the Company. During the Offer, the Purchaser and Weyerhaeuser intend to
have ongoing contacts and negotiations with the Company and its directors,
officers and stockholders.

12. Purpose of the Offer; the Merger Agreement; the Partnership Agreement;
Certain Other Agreements

 Purpose

  The purpose of the Offer is to enable Weyerhaeuser to acquire control of the
Company and to acquire all of the outstanding Shares. The Offer, as the first
step in the acquisition of the Company, is intended to facilitate the
acquisition of all of the outstanding Shares. The purpose of the Merger is to
acquire all outstanding Shares not tendered and purchased pursuant to the
Offer or otherwise.

 The Merger Agreement

  The Merger Agreement provides that following the satisfaction or waiver of
the conditions described below under "Conditions to the Merger", the Purchaser
will be merged with and into the Company, and each issued Share (other than
Shares owned by Weyerhaeuser, the Purchaser or the Company or a wholly-owned
subsidiary of Weyerhaeuser, the Purchaser or the Company or by stockholders,
if any, who are entitled to and who properly exercise appraisal rights under
Delaware law) will be converted into the right to receive an amount in cash
equal to the price per Share paid pursuant to the Offer.

  Vote Required To Approve Merger. The Delaware General Corporation Law
("DGCL") requires, among other things, that the adoption of any plan of merger
or consolidation of the Company must be approved by the Board of Directors,
and, if the "short-form" merger procedure described below is not available,
adopted by the Company's stockholders. The Board of Directors of the Company
has approved the Offer, the Merger and the Merger Agreement; consequently, the
only additional action of the Company that may be necessary to effect the
Merger is adoption of the Merger Agreement by the Company's stockholders if
such "short-form" merger procedure is not available. Under the DGCL, if
stockholder adoption of the Merger Agreement is required in order to
consummate the Merger, the vote required is the affirmative vote of the
holders of a majority of the outstanding Shares (including any Shares owned by
the Purchaser) voting together as a single class. If the Purchaser acquires,
through the Offer, the Merger Agreement or otherwise, voting power with
respect to at least a majority of the outstanding Shares (which would be the
case if the Minimum Condition were satisfied and the Purchaser were to accept
for payment Shares tendered pursuant to the Offer), it would have sufficient
voting power to effect the Merger without the affirmative vote of any other
stockholder of the Company.

                                      20
<PAGE>

  The DGCL also provides that if a parent company owns at least 90% of the
outstanding shares of each class of stock of a subsidiary, the parent company
may merge that subsidiary into the parent company, or the parent company may
merge itself into that subsidiary, pursuant to "short-form" merger procedures
without prior notice to, or the approval of, the other stockholders of the
subsidiary. In order to consummate the Merger pursuant to the provisions of
the DGCL, the Purchaser would have to own at least 90% of the outstanding
Common Shares and at least 90% of the outstanding Preferred Shares.

  All the outstanding Preferred Shares are held by the trustee for the
Company's Investment Plan. Upon any transfer of Preferred Shares to the
Purchaser or Weyerhaeuser pursuant to the Offer or otherwise, such Preferred
Shares will automatically convert into Common Shares in accordance with their
terms. Accordingly, unless all the outstanding Preferred Shares are tendered
pursuant to the Offer and purchased by the Purchaser or otherwise acquired by
the Purchaser or Weyerhaeuser, the Purchaser and Weyerhaeuser will not own 90%
of the Preferred Shares remaining outstanding.

  The Merger Agreement provides that if, upon consummation of the Offer, the
Purchaser owns a number of Common Shares that, together with the Common Shares
that the Purchaser has the option to purchase pursuant to the provision
described in the next paragraph, equals at least 90% of the then outstanding
Common Shares (after giving effect to the exercise of such option) then the
Company shall take such action as is requested by Weyerhaeuser and permitted
by the certificate of designation for the Preferred Shares and applicable law
to terminate and or amend the employee stock ownership portion of the
Company's Investment Plan (the "ESOP") and to call for redemption all of the
then-outstanding Preferred Shares as promptly as practicable after such
request by Weyerhaeuser. Upon such redemption of the Preferred Shares, no
Preferred Shares would remain outstanding and the Purchaser would own, or have
the ability to own, 90% of the then outstanding Common Shares (after giving
effect to the exercise of the option described in the next paragraph).

  As part of the Merger Agreement, the Company has granted to the Purchaser an
option to purchase such number of Common Shares for a price of $42 per Common
Share that, when added to the number of Common Shares owned by Weyerhaeuser
and the Purchaser immediately prior to the exercise of the option, would
result in the Purchaser owning immediately after the exercise 90% of the then
outstanding Common Shares. The Purchaser may exercise the option only if, at
the time of exercise of the option, Weyerhaeuser, the Purchaser and any other
subsidiary of Weyerhaeuser own at least 50.1% of the Fully Diluted Shares (as
defined in Section 14). See "Grant of Conditional Option" below.

  Although Weyerhaeuser and the Purchaser have the ability, through their
rights to cause the Company to redeem the Preferred Shares and their option to
purchase Common Shares, to obtain the ownership levels necessary to consummate
the Merger using the "short-form" merger procedure, their ability to cause the
redemption of the Preferred Shares and exercise the option for Common Shares
is subject to certain contingencies and they cannot provide any assurance that
they will be successful. In addition, Weyerhaeuser and the Purchaser are not
obliged to do anything in this regard. Accordingly, no assurance can be given
that the Merger can or will be consummated as a "short form" merger without
approval by the stockholders of the Company.

  Conditions to the Merger. The Merger Agreement provides that the respective
obligations of each party to effect the Merger are subject to the satisfaction
or waiver of certain conditions, including the following: (a) if required by
applicable law, the Merger Agreement having been approved and adopted by the
affirmative vote of the holders of a majority of the Shares; (b) no temporary
restraining order, preliminary or permanent injunction or other order issued
by any court of competent jurisdiction or other legal restraint or prohibition
preventing the consummation of the Merger being in effect; provided, however,
that each of the Company, the Purchaser and Weyerhaeuser has used all
reasonable efforts to prevent the entry of any such injunction or other order
and to appeal as promptly as possible any such injunction or other order that
may have been entered; and (c) the Purchaser having previously accepted for
payment and paid for Shares pursuant to the Offer.


                                      21
<PAGE>

  Termination of the Merger Agreement. The Merger Agreement may be terminated
at any time prior to the effective time of the Merger, whether before or after
adoption of the Merger Agreement by the stockholders of the Company:

    (1) by mutual written consent of Weyerhaeuser, the Purchaser and the
  Company; provided that, any such consent shall require the concurrence of a
  majority of the independent directors of the Company if it occurs after the
  purchase of Shares pursuant to the Offer;

    (2) by either Weyerhaeuser or the Company;

      (a) if the Offer is not consummated on or before April 3, 2000 (the
    "Outside Date"), unless the failure to consummate the Offer is the
    result of a material breach of the Merger Agreement by the party
    seeking to terminate the Merger Agreement; provided, however, that the
    passage of such period will be tolled for any part thereof during which
    any party is subject to a nonfinal order, decree, ruling or action
    restraining, enjoining or otherwise prohibiting the consummation of the
    Offer and the Outside Date shall be extended day-by-day for each day
    tolled: provided further, however, that the Outside Date shall not be
    extended past May 18, 2000;

      (b) if any federal, state, local or foreign government or any court
    of competent jurisdiction, administrative agency or commission or other
    governmental authority or instrumentality, domestic or foreign (a
    "Governmental Entity"), issues an order, decree or ruling or takes any
    other action permanently enjoining, restraining or otherwise
    prohibiting the Merger and such order, decree, ruling or other action
    has become final and nonappealable; or

      (c) if as the result of the failure of any of the conditions to the
    Offer set forth in Section 14, the Offer has terminated or expired in
    accordance with its terms and the terms of the Merger Agreement without
    the Purchaser having purchased any Shares pursuant to the Offer;
    provided, however, that the right to terminate the Merger Agreement
    pursuant to the terms of this clause (c) will not be available to any
    party whose failure to fulfill any of its obligations under the Merger
    Agreement results in the failure of such condition;

    (3) by Weyerhaeuser if, prior to the consummation of the Offer, the
  Company breaches or fails to perform in any material respect any of its
  representations, warranties or covenants contained in the Merger Agreement,
  which breach or failure to perform (a) would give rise to the failure of a
  condition set forth in Section 14 and (b) has not been or is not capable of
  being cured within 30 days of the giving of written notice to the Company
  of such breach, provided that Weyerhaeuser is not then in material breach

      (a) if the Board of Directors of the Company or any committee thereof

      (b) if the Board of Directors of the Company fails to reaffirm
    publicly and unconditionally within ten business days after
    Weyerhaeuser's written request to do so (which request may be made at
    any time that a Takeover Proposal is pending and not withdrawn) and
    must also include the unconditional rejection of such Takeover Proposal
    (to the extent not previously withdrawn) its recommendation to the
    Company's stockholders that they give the Stockholder Approval;
    provided, however, that Weyerhaeuser may not request the Board of
    Directors of the Company to make more than one such reaffirmation in
    respect of any Takeover Proposal unless such Takeover Proposal has been
    materially amended or modified (and not withdrawn);

    (5) by the Company if, prior to the acceptance of Shares for payment

  material respect any of its representations, warranties or covenants
  contained in the Merger Agreement, which breach or failure to perform has
  not or is not capable

                                      22

  of being cured within 30 days after the giving of written notice to
  Weyerhaeuser of such breach provided that the Company is not then in
  material breach of any representation, warranty or covenant contained in
  the Merger Agreement);

    (6) by the Company prior to the acceptance of Shares for payment pursuant
  to the Offer in accordance with the terms of the Merger Agreement described
  in the second paragraph below under "Takeover Proposals", provided it has
  complied with all provisions described in the second paragraph under
  "Takeover Proposals", including the notice provisions therein; or

    (7) by the Company if the offer has not been commenced within seven
  business days after the date of the Merger Agreement (satisfied by the
  commencement of this Offer); or

    (8) by the Company if any event occurs which would result in the
  condition set forth in paragraph (d) of Section 14 not being satisfied, and
  five business days have elapsed since such occurrence, unless Weyerhaeuser
  shall have waived its right to terminate this Agreement and its right not
  to consummate the Offer for the failure of such condition resulting from
  such event.

  Takeover Proposals. The Merger Agreement provides that the Company will not,
nor will it permit any of its subsidiaries to, nor will it authorize any
officer, director or employee of, or any investment banker, attorney or other
advisor or representative of, the Company or any of its subsidiaries to (1)
solicit, initiate or knowingly encourage the submission of any Takeover
Proposal, (2) enter into any agreement with respect to any Takeover Proposal
or (3) participate in any discussions or negotiations regarding, or furnish to
any person any information with respect to, or take any other action to
knowingly facilitate any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Takeover Proposal;
provided, however, that, at any time during the period following the execution
of the Merger Agreement and prior to the consummation of the Offer (the
"Applicable Period"), if the Company receives a proposal or offer that was not
solicited by the Company and that did not otherwise result from a breach of
these provisions and that the Board of Directors of the Company determines in
good faith (based on consultation with its outside counsel and a financial
advisor of nationally recognized reputation) could result in a third party
making a Superior Proposal (as defined below, including the determination by
the Board of Directors of the Company set forth in such definition), and
subject to compliance with the notice provisions described in the second
succeeding paragraph below, the Company may, to the extent necessary to comply
with the fiduciary obligations of the Board of Directors of the Company, as
determined in good faith by it after consultation with outside counsel, (A)
furnish information with respect to the Company to the person making such
proposal or offer pursuant to a customary confidentiality agreement as
determined by the Company after consultation with its outside counsel, and (B)
participate in discussions or negotiations with such person regarding such
proposal or offer. The Merger Agreement provides that any action that is in
violation of the restrictions set forth in the preceding sentence by any
executive officer of the Company or any of its subsidiaries or any affiliate,
director or investment banker, attorney or other advisor or representative of
the Company or any of the Company's subsidiaries, shall be deemed to be a
breach of the provisions described in this paragraph by the Company. The
Merger Agreement provides that the Company shall, and shall cause its officers
and directors, and any investment banker, attorney or other advisor or
representative of the Company or any subsidiary of the Company, to cease
immediately all discussions and negotiations regarding any proposal that
constitutes, or may reasonably be expected to lead to, a Takeover Proposal.
The Merger Agreement defines "Takeover Proposal" as any inquiry, proposal or
offer for a merger, consolidation, dissolution, liquidation, recapitalization
or other business combination involving the Company or any subsidiary of the
Company, any proposal or offer for the issuance by the Company of over 15% of
its equity securities as consideration for the assets or securities of any
person or any proposal or offer to acquire in any manner, directly or
indirectly, over 15% of the equity securities or consolidated total assets of
the Company in each case, other than the transactions contemplated by the
Merger Agreement.

  The Merger Agreement further provides that, except as described below,
neither the Board of Directors of the Company nor any committee thereof may
approve any letter of intent, agreement in principle (although no additional
time period shall be required following such determinations), acquisition
agreement or similar agreement (an "Acquisition Agreement") related to any
Takeover Proposal or approve or recommend, or propose

                                      23
<PAGE>

to approve or recommend, any Takeover Proposal. The Company may terminate the
Merger Agreement pursuant to clause (6) under "Termination of the Merger
Agreement" only if (i) the Board of Directors of the Company has received a
Superior Proposal (as defined below), (ii) in light of such Superior Proposal
the Board of Directors of the Company has determined in good faith, after
consultation with outside counsel, that it is necessary for the Board of
Directors of the Company to withdraw or modify its approval or recommendation
of the Merger Agreement, the Offer or the Merger in order to comply with its
fiduciary obligations, (iii) the Company has notified Weyerhaeuser in writing
of the determinations described in clause (ii) above, (iv) at least three
business days following receipt by Weyerhaeuser of the notice referred to in
clause (iii) above, and taking into account any revised proposal by
Weyerhaeuser since the receipt of the notice referred to in clause (iii)
above, such Superior Proposal remains a Superior Proposal and the Board of
Directors of the Company has again made the determinations referred to in
clause (ii) above (although no additional time period shall be required
following such determinations), (v) the Company is in compliance with its
obligations with respect to Takeover Proposals, (vi) the Board of Directors of
the Company concurrently approves, and the Company concurrently enters into, a
definitive agreement providing for the implementation of such Superior
Proposal, (vii) such definitive agreement contains the guarantee described
below under "Waiver Under Partnership Agreement" and (viii) Weyerhaeuser is
not at such time entitled to terminate the Merger Agreement pursuant to clause
(3) under "Termination of the Merger Agreement" above solely as a result of a
knowing and deliberate breach by the Company of a representation or warranty
in the Merger Agreement or a material breach by the Company of a covenant in
the Merger Agreement. The Merger Agreement defines "Superior Proposal" as any
proposal made by a third party to acquire all or substantially all of the
equity securities or assets of the Company, pursuant to a tender or exchange
offer, a merger, a consolidation, a liquidation or dissolution, a
recapitalization, a sale of its assets or otherwise, which a majority of the
disinterested directors of the Company determines in its good faith judgment
to be (i) on terms superior from a financial point of view to the holders of
Shares than the transactions contemplated by the Merger Agreement (based on
consultation with the Company's independent financial advisor), taking into
account all the terms and conditions of such proposal and the Merger Agreement
(including any proposal by Weyerhaeuser to amend the terms of the transactions
contemplated by the Merger Agreement) and (ii) reasonably capable of being
completed, taking into account all financial, regulatory, legal and other
aspects of such proposal.

  In addition to the obligations of the Company described in the preceding two
paragraphs, the Merger Agreement provides that the Company will promptly
advise Weyerhaeuser orally and in writing of any Takeover Proposal or any
inquiry with respect to or that could reasonably be expected to lead to any
Takeover Proposal, the identity of the person making any such Takeover
Proposal or inquiry and the material terms of any such Takeover Proposal or
inquiry. The Company is further required under the terms of the Merger
Agreement to (i) keep Weyerhaeuser fully informed of the status of any such
Takeover Proposal or inquiry and (ii) provide to Weyerhaeuser as soon as
practicable after receipt or delivery thereof with copies of all
correspondence and other written material sent or provided to the Company from
any third party in connection with any Takeover Proposal; provided, however,
that the Company shall not be required to provide any nonpublic information
specified in this clause (ii) regarding the business or financial condition or
prospects of such third party if (A) the Company is prohibited from disclosing
such information pursuant to a legally binding confidentiality agreement and
(B) such Takeover Proposal provides for consideration consisting solely of
cash.

  The Merger Agreement provides that nothing contained in this section
entitled "Takeover Proposals" will prohibit the Company from taking and
disclosing to its stockholders a position contemplated by Rule 14e-2(a)
promulgated under the Exchange Act or from making any disclosure to the
Company's stockholders if, in the good faith judgment of the Board of
Directors of the Company, after consultation with outside counsel, failure so
to disclose would be inconsistent with applicable law; provided, however, that
neither the Company nor its Board of Directors nor any committee thereof may
withdraw or modify, or propose publicly to withdraw or modify, in a manner
adverse to Weyerhaeuser or the Purchaser, the approval or recommendation of
the Board of Directors of the Company of the Merger, the Offer or the Merger
Agreement or approve or recommend, or propose publicly to approve or
recommend, a Takeover Proposal unless a withdrawal or modification of such
approval or recommendation is, in the good faith judgment of the Board of
Directors of the Company after consultation with its outside counsel,
necessary to comply with its fiduciary obligations.

or not the Merger is consummated.

  The Merger Agreement further provides that the Company will pay in same-day
funds to Weyerhaeuser (a) a fee of $12,500,000 if the Merger Agreement is
terminated in accordance with the provisions described above in clause (6)
under "Termination of the Merger Agreement"; (b) in addition to the fee paid

the Merger Agreement is terminated in accordance with the provisions described
above in clause (4) under "Termination of the Merger Agreement"; (d) in

(i) after the date of the Merger Agreement and prior to the termination of the
Merger Agreement, any person makes a Takeover Proposal, (ii) the Offer remains

Takeover Proposal is made (or such later date as the Offer may be extended at
the Company's request pursuant to the Merger Agreement), (iii) the Minimum

$25,000,000 if (i) after the date of the Merger Agreement and prior to the
termination of the Merger Agreement, any person makes a Takeover Proposal,
(ii) the Offer remains open until the scheduled expiration date immediately
following the date such Takeover Proposal is made (or such later date as the
Offer may be extended at the Company's request pursuant to the Merger
Agreement), (iii) the Minimum Condition is not satisfied at the expiration of
the Offer, (iv) the Merger Agreement is terminated pursuant to clause (2)(c)
of "Termination of the Merger Agreement" above; and (v) within 12 months of
such termination an Acquisition Proposal is consummated. The Merger Agreement
provides that under no circumstances will the Company be obligated to pay fees
as described in this paragraph in excess of $25,000,000 in the aggregate. The
Merger Agreement defines "Acquisition Proposal" to mean a Takeover Proposal,
provided that for the purpose of this definition, each reference to "15%" in
the definition of Takeover Proposal shall be deemed a reference to "50%".

  Conduct of Business. The Merger Agreement provides that, except as
contemplated or permitted by the terms of the Merger Agreement from the date
of the Merger Agreement to the effective time of the Merger or earlier
termination of the Merger Agreement, the Company will, and will cause its
subsidiaries to, conduct their respective business in the usual and ordinary
course consistent with past practice except as required to comply with changes
in applicable law occurring after the date of the Merger Agreement and, to the
extent consistent therewith, use all reasonable efforts to preserve intact
their current business organizations and keep available the services of their
current officers and employees to maintain their respective goodwill and
ongoing business, in addition, and without limiting the generality of the

as to Material Adverse Effect becoming untrue, (b) any of such representations
and warranties that is not so qualified becoming untrue in any material
respect or (c) any of the conditions to the Merger described under "Conditions

  Board of Directors. The Merger Agreement provides that promptly upon the
acceptance for payment of, and payment by the Board of Directors of the
Company for, Shares pursuant to the Offer, the Purchaser will be entitled to
designate such number of directors on the Board of Directors of the Company as
will give the Purchaser, subject to compliance with Section 14(f) of the
Exchange Act, representation on the Board of Directors of the Company equal to
at least that number of directors, rounded up to the next whole number, which
is the product of (a) the total number of directors on the Board of Directors
of the Company (giving effect to the directors elected pursuant to this
sentence) multiplied by (b) the percentage that (i) such number of Shares so
accepted for payment and paid for by the Purchaser plus the number of Shares
otherwise owned by the Purchaser or any other subsidiary of Weyerhaeuser bears
to (ii) the number of Fully Diluted Shares (as defined in Section 14), and the
Company will, at such time, cause the Purchaser's designees to be so elected;
provided, however, that in the event that the Purchaser's designees are
appointed or elected to the Board of Directors of the Company, until the
effective time of the Merger, the Board of Directors of the Company will
include at least three directors who were directors of the Company as of the
date of the Merger Agreement and who are not

                                      27
<PAGE>

officers of the Company ("Independent Directors"); and provided further,
however, that, in such event, if the number of Independent Directors shall be
reduced below three for any reason whatsoever, any remaining Independent
Directors (or Independent Director, if there shall be only one remaining)
shall be entitled to designate persons to fill such vacancies who shall be
deemed to be Independent Directors for purposes of the Merger Agreement or, if
no Independent Directors then remain, the other directors shall designate
three persons to fill such vacancies who are not officers, stockholders or
affiliates of the Company, Weyerhaeuser or the Purchaser, and such persons
shall be deemed to be Independent Directors for purposes of the Merger
Agreement. Subject to applicable law, the Company has agreed to take all
action requested by Weyerhaeuser necessary to effect any such election,
including mailing to its stockholders the Information Statement containing the
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder, which Information Statement is attached as Annex A to
the Schedule 14D-9 (provided that the Purchaser shall have provided to the
Company on a timely basis all information required in the Information
Statement with respect to the Purchaser's designees). In connection with the
foregoing, the Company promptly shall, at the option of the Purchaser, use all
reasonable efforts to either increase the size of the Company Board or obtain
the resignation of such number of its current directors as is necessary to
enable the Purchaser's designees to be elected or appointed to the Company
Board as provided above. See "Plans for the Company" below.

  Following the election or appointment of the Purchaser's designees pursuant
to the provisions described in this section, and prior to the effective time
of the Merger, any amendment or termination of the Merger Agreement approved
by the Company, extension for the performance or waiver of the obligations of
Weyerhaeuser or the Purchaser or waiver of the Company's rights hereunder
shall require the concurrence of a majority of the Independent Directors.

  Stock Options. The Merger Agreement provides that as soon as practicable
after the date of the Merger Agreement, the Board of Directors of the Company
(or, if appropriate, any committee administering the Company Stock Plans)
shall adopt such resolutions or take such other actions as are required,
subject to any required consent of the holders, to adjust the terms of all
outstanding Company Employee Stock Options and all outstanding Company SARs
heretofore granted under any Company Stock Plan to provide that each Company
Employee Stock Option (and any Company SAR related thereto) outstanding
immediately prior to the acceptance for payment of Common Shares pursuant to
the Offer shall be canceled in exchange for a cash payment by the Company at
that time of an amount equal to (i) the excess, if any, of (x) the
consideration payable pursuant to the Merger over (y) the exercise price per
Common Share subject to such Company Employee Stock Option, multiplied by (ii)
the number of Common Shares for which such Company Employee Stock Option shall
not theretofore have been exercised. The Merger Agreement defines (a) "Company
Employee Stock Option" as any option to purchase Common Stock granted under
any Company Stock Plan, (b) "Company SAR" as any stock appreciation right
linked to the price of Common Stock and granted under any Company Stock Plan,
and (c) "Company Stock Plans" as the Company's Key Employees' 1992 Stock
Option Plan, Key Employees' 1993 Stock Option Plan, Amended and Restated
Restricted Stock Plan for Non-Employee Directors, Key Employees' 1982
Incentive Stock Option Plan, as amended, 1985 Incentive Stock Option Plan, as
amended, 1998 Stock Option Plan, as amended, Non-Employee Directors 1997 Stock
Plan and 1996 Stock Option Plan.

  The Merger Agreement provides that the Company shall use its reasonable best
efforts to obtain all consents of the holders of the Company Employee Stock
Options as shall be necessary to effectuate the provisions described in the
prior paragraphs and to ensure that following the effective time of the Merger
no holder of a Company Employee Stock Option or Company SAR or any participant
in any Company Stock Plan or other Company Benefit Plan shall have any right
thereunder to acquire any capital stock of the Company or the surviving
corporation. Notwithstanding anything to the contrary contained in the Merger
Agreement, payment shall, at Weyerhaeuser's request, be withheld in respect of
a Company Employee Stock Option until all necessary consents in respect of
such Company Employee Stock Option are obtained.

  The Merger Agreement provides that the Company Stock Plans shall terminate
as of the effective time of the Merger, and the provisions in any other
Benefit Plan providing for the issuance, transfer or grant of any capital
stock of the Company or any interest in respect of any capital stock of the
Company shall be deleted as of the effective time of the Merger.

                                      28

  Existing Agreements, Plans and Policies. The Merger Agreement provides that
from and after the effective time of the Merger, Weyerhaeuser will and will
cause the surviving corporation to honor in accordance with their respective
terms (as in effect on the date of the Merger Agreement), all the Company's
employment, severance and termination agreements, plans and policies disclosed
to Weyerhaeuser.

  If prior to the effective time Weyerhaeuser agrees to grant options to
acquire common stock of Weyerhaeuser to any officer or director of the Company
prior to the effective time of the Merger, the Board of Directors of
Weyerhaeuser, or an appropriate committee of non-employee directors thereof,
shall if necessary adopt a resolution consistent with the interpretive
guidance of the Commission so that the acquisition by any officer or director
of the Company who may become a covered person of Weyerhaeuser for purposes of
Section 16 of the Exchange Act and the rules and regulations thereunder
("Section 16") of options to acquire common stock of Weyerhaeuser pursuant to
the Merger Agreement and the Merger shall be an exempt transaction for
purposes of Section 16.

  For a period of not less than one year following the effective time of the
Merger, Weyerhaeuser shall provide, or shall cause to be provided, to current
employees of the Company and its subsidiaries (the "Company Employees"), taken
as a whole, employee benefits that are, in the aggregate, no less favorable
than those provided from time to time after the effective time of the Merger
to employees of Weyerhaeuser and its subsidiaries who are similarly situated,
in terms of positions and geographic locations, to such Company Employees;
provided, however, that nothing described in this paragraph shall require
Weyerhaeuser to continue or cause to be continued any Company Stock Plan.
Without limiting the generality of the foregoing, all Company Employees who
are covered by the Company's Severance Pay Plan as in effect on the date
hereof and whose employment is terminated on or before the first anniversary
of the effective time of the Merger shall be provided with severance pay and
benefits on a basis, and in amounts, not less favorable than those provided
for under the Company's Severance Pay Plan.

  For all purposes under the employee benefit plans of Weyerhaeuser and its
affiliates providing benefits to any Company Employees after the effective
time of the Merger (the "New Plans"), each Company Employee shall be credited
with his or her years of service with the Company and its affiliates before
the effective time of the Merger, to the same extent as such Company Employee
was entitled, before the effective time of the Merger, to credit for such
service under any similar Company Benefit Plans, except for purposes of
benefit accrual under defined benefit pension plans. In addition, and without
limiting the generality of the foregoing: (i) each Company Employee shall be
immediately eligible to participate, without any waiting time, in any and all
New Plans to the extent coverage under such New Plan replaces coverage under a
comparable Company Benefit Plan in which such Company Employee participated
immediately before the effective time of the Merger and previously described
to Weyerhaeuser (such plans, collectively, the "Old Plans"); and (ii) for
purposes of each New Plan providing medical, dental, pharmaceutical and/or
vision benefits to any Company Employee, Weyerhaeuser shall cause all pre-
existing condition exclusions and actively-at-work requirements of such New
Plan to be waived for such employee and his or her covered dependents (other
than limitations or waiting periods that are already in effect with respect to
such employees and dependents and that have not been satisfied as of the
effective time of the Merger), and Weyerhaeuser shall cause any eligible
expenses incurred by such employee and his or her covered dependents during
the portion of the plan year of the Old Plan ending on the date such
employee's participation in the corresponding New Plan begins to be taken into
account under such New Plan for purposes of satisfying all deductible,
coinsurance and maximum out-of-pocket requirements applicable to such employee
and his or her covered dependents for the applicable plan year as if such
amounts had been paid in accordance with such New Plan.

  Under the Merger Agreement, Weyerhaeuser agrees that for purposes of any of
the Company Benefit Plans conferring rights on a current or former employee,
officer or director as a result of a change of control of the Company, the
consummation of the Merger (or such earlier event contemplated by the Merger
Agreement and specified in such Company Benefit Plans) shall be deemed to
constitute a "Change of Control" (as that term is defined in such Company
Benefit Plans).


                                      29
<PAGE>

  Subject to compliance by Weyerhaeuser with its obligations described under
the first and third paragraphs of this section entitled "Existing Agreement
Plans and Policies", nothing described in this section or elsewhere in the
Merger Agreement shall be construed to prevent the termination of employment
of any Company Employee or any change in the employee benefits available to
any Company Employee or the amendment or termination of any particular Company
Benefit Plan to the extent permitted by its terms as in effect immediately
prior to the effective time of the Merger.

  Indemnification. Weyerhaeuser has agreed, to the fullest extent permitted by
law: (a) to cause the surviving corporation to honor all the Company's
obligations to indemnify (including any obligations to advance funds for
expenses) the current or former directors or officers of the Company and its
subsidiaries for acts or omissions by such directors and officers occurring at
or prior to the effective time of the Merger to the extent that such
obligations of the Company exist on the date of the Merger Agreement, whether
pursuant to the Restated Certificate of Incorporation, as amended, or By-laws,
as amended, of the Company, individual indemnity agreements or otherwise and
that such obligations will survive the Merger and will continue in full force
and effect in accordance with the terms of the Restated Certificate of
Incorporation, as amended, and By-laws, as amended, of the Company and such
individual indemnity agreements from the effective time of the Merger until
the expiration of the applicable statute of limitations with respect to any
claims against such directors or officers arising out of such acts or
omissions; and (b) for a period of six years after the effective time of the
Merger, to cause to be maintained in effect the current policies of directors'
and officers' liability insurance maintained by the Company (provided that
Weyerhaeuser may substitute therefor policies with reputable and financially
sound carriers of at least the same coverage and amounts containing terms and
conditions which are no less advantageous) with respect to claims arising from
or related to facts or events which occurred at or before the effective time
of the Merger, provided, however, that Weyerhaeuser will not be obligated to
make annual premium payments for such insurance to the extent such premiums
exceed 300% of the annual premiums paid as of the date hereof by the Company
for such insurance (such 300% amount, the "Maximum Amount") . If such
insurance coverage cannot be obtained at all, or can only be obtained at an
annual premium in excess of the Maximum Amount, Weyerhaeuser will maintain the
most advantageous policies of directors' and officers' insurance obtainable
for an annual premium equal to such amount; provided, however, that if such
insurance coverage cannot be obtained at all, Weyerhaeuser shall purchase all
available extended reporting periods with respect to pre-existing insurance in
an amount which, together with all other insurance purchased pursuant to
clause (b) above, does not exceed the Maximum Amount. The Merger Agreement
further provides that Weyerhaeuser will not, and will cause the Company not
to, take any action that would have the effect of limiting the aggregate
amount of insurance coverage required to be maintained for the individuals
referred to in clause (b) above.

  Weyerhaeuser has also agreed that: (a) from and after the consummation of
the Offer, to the full extent permitted by law, Weyerhaeuser will, and will
cause the Company (or any successor to the Company) to, indemnify, defend and
hold harmless the present officers and directors of the Company and its
subsidiaries (each an "Indemnified Party") against all losses, claims,
damages, liabilities, fees and expenses (including attorneys' fees and
disbursements) , judgments, fines and amounts paid in settlement
(collectively, "Losses") arising out of actions or omissions occurring at or
prior to the effective time of the Merger in connection with the Merger
Agreement, the Offer, the Merger and the other transactions contemplated by
the Merger Agreement; provided, however, that an Indemnified Party shall not
be entitled to indemnification under this clause (a) for Losses arising out of
actions or omissions by the Indemnified Party constituting (i) a breach of the
Merger Agreement or the Stockholder Agreement, (ii) criminal conduct or (iii)
any violation of federal, state or foreign securities laws; and provided
further, however, that in order to be entitled to indemnification under this
clause (a), an Indemnified Party must give Weyerhaeuser and the Company
written notice of any third party claim which may give rise to any indemnity
obligation under this clause (a), and Weyerhaeuser and the Company shall have
the right to assume the defense of any such claim through counsel of their own
choosing (subject to such counsel's reasonable judgment that separate defenses
that would create a conflict of interest on the part of such counsel are not
available), provided that if Weyerhaeuser and the Company do not assume any
such defense, they shall be liable for all reasonable costs and expenses of
defending such claim incurred by the Indemnified Party, including

                                      30
<PAGE>

reasonable fees and disbursements of counsel and shall advance such reasonable
costs and expenses to the Indemnified Party; provided, however, that such
advance shall be made only after receiving an undertaking from the Indemnified
Party that such advance shall be repaid if it is determined that such
Indemnified Party is not entitled to indemnification therefor and that neither
Weyerhaeuser nor the Company shall be liable under this clause (a) for any
Losses resulting from any settlement, compromise or offer to settle or
compromise any such claim or litigation or other action, without the prior
written consent of Weyerhaeuser and the Company; (b) the Company shall not,
and Weyerhaeuser shall not permit the Company to, amend or repeal any
provision of the Restated Certificate of Incorporation or By-laws of the
Company after the consummation of the Offer if such action would adversely
affect the rights of individuals who on or prior to the consummation of the
Offer were entitled to advances, indemnification or exculpation thereunder,
for actions or omissions by such individuals prior to the effective time of
the Merger provided, that the individuals referred to in this clause (b) shall
include any individuals who served as of the effective time of the Merger as
directors or officers of any subsidiary of the Company at the Company's
request, it being acknowledged by the parties hereto that each director or
officer of the Company who is currently serving as a director or officer of a
subsidiary of the Company is doing so at such request of the Company; and (c)
in the event the surviving corporation or any successor to the surviving
corporation (i) consolidates with or merges into any other person and shall
not be the continuing or surviving corporation or entity in such consolidation
or merger or (ii) transfers all or substantially all its properties and assets
to any person, then, and in each case, proper provision shall be made so that
the successors of the surviving corporation honor the obligations of the
Company set forth in the provisions of the Merger Agreement described, in this
and the immediately preceding paragraph.

  Reasonable Efforts; Notification. The Merger Agreement provides that: (a)
upon the terms and subject to the conditions set forth in the Merger
Agreement, each of the Company, Weyerhaeuser and the Purchaser will use all
reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, and to assist and cooperate with the other parties in doing,
all things necessary, proper or advisable to consummate and make effective, in
the most expeditious manner practicable, the Offer, the Merger and the other
transactions contemplated by the Merger Agreement, including (i) the obtaining
of all necessary actions or nonactions and Consents (as defined below) from
Governmental Entities and the making of all necessary registrations and
filings (including filings with Governmental Entities, if any) and the taking
of all reasonable steps as may be necessary to obtain an approval or waiver
from, or to avoid an action or proceeding by, any Governmental Entity, (ii)
the obtaining of all necessary Consents waivers from third parties, (iii) the
defending of any lawsuits or other legal proceedings, whether judicial or
administrative, challenging the Merger Agreement or the consummation of the
transactions contemplated thereby, including seeking to have any stay or
temporary restraining order entered by any court or other Governmental Entity
vacated or reversed and (iv) the execution and delivery of any additional
instruments necessary to consummate the transactions contemplated by the
Merger Agreement and to fully carry out the purposes of the Merger Agreement;
(b) in connection with and without limiting the foregoing, the Company and the
Board of Directors of the Company will, if any state takeover statute or
similar statute or regulation is or becomes applicable to any transaction
contemplated by the Merger Agreement, take all action necessary to ensure that
the Offer, the Merger and the transactions contemplated by the Merger
Agreement may be consummated as promptly as practicable on the terms
contemplated by the Merger Agreement; provided, however, that nothing in
clause (a) or (b) will prevent the Company from taking any action permitted in
the second paragraph under "Takeover Proposals" and that nothing in the Merger
Agreement will require any party to take any action that would result in any
of the consequences referred to in paragraph (a) of Section 14; and (c) the
Company shall give prompt notice to Weyerhaeuser of (i) any representation or
warranty made by it contained in the Merger Agreement that is qualified as to
a Material Adverse Effect becoming untrue or inaccurate in any respect or any
such representation or warranty that is not so qualified becoming untrue or
inaccurate in any material respect or (ii) the failure by it to comply with or
satisfy in any material respect any covenant, condition or agreement to be
complied with or satisfied by it under the Merger Agreement; provided,
however, that no such notification shall affect the representations,
warranties, covenants or agreements of the parties or the conditions to the
obligations of the parties under the Merger Agreement. The Merger Agreement
defines "Consent" to mean any consent, approval, license, permit, order or
authorization of a governmental entity. The Merger Agreement defines "Material
Adverse Effect" on a party as a material adverse effect on the

                                      31
<PAGE>

business, financial condition, as ongoing, longer-term profitability (but not
prospects) of such party and its subsidiaries.

  Representations and Warranties. The Merger Agreement contains various
customary representations and warranties.

  Procedure for Termination, Amendment, Extension or Waiver. The Merger
Agreement provides that following the election or appointment of the
Purchaser's designees to the Board of Directors of the Company as described
above under "Board of Directors", prior to the effective time of the Merger,
any amendment or termination of the Merger Agreement, extension for the
performance or waiver of the obligations of Weyerhaeuser or the Purchaser or
waiver of the Company's rights thereunder will require the concurrence of a
majority of the directors of the Company who were directors on the date of the
Merger Agreement and who are not officers of the Company.

  Rights Agreement. The Rights Agreement has been amended as of November 23,
1999 to render the Rights inapplicable to the Merger Agreement, the Offer, the
Merger and the other transactions contemplated by the Merger Agreement. The
Company has agreed that neither it nor the Board of Directors will, without
the prior consent of Weyerhaeuser, (i) further amend the Rights Agreement,
(ii) redeem the Rights or (iii) take any action with respect to, or make any
determination under, the Rights Agreement, except, in each case, to the extent
necessary to comply with the fiduciary obligations of the Board of Directors
of the Company as determined by it in good faith after consultation with
outside counsel.

  Waiver Under Partnership Agreement. The Company has waived, and agreed to
cause any of its subsidiaries with a partnership interest under the
Partnership Agreement to waive, any rights they may have described below under
"Partnership Agreement" to exercise (x) the "sell procedure" or (y) the
"mandatory buy/sell procedure" (the rights referred to in clauses (x) and (y),
together with the "buy procedure" described below under "Partnership
Agreement", are referred to as the "Buy/Sell Rights"), in each case, as result
of the consummation of the MB Transaction. In the Merger Agreement, the
Company acknowledges that Weyerhaeuser does not agree that the Company is
entitled to exercise any of the Buy/Sell Rights as a result of the MB
Transaction, and Weyerhaeuser acknowledges that the Company believes that it
is entitled to exercise the Buy/Sell Rights as a result of the MB Transaction.

  The Merger Agreement provides that if the Merger Agreement is terminated
pursuant to clause (6) under "Termination of the Merger Agreement", the
Company will, subject to the next sentence, purchase the entire partnership
interest (the "Weyerhaeuser Interest") of Weyerhaeuser and its subsidiaries in
the Partnership, and Weyerhaeuser will, and will cause its subsidiaries to, in
each case subject to the next sentence, sell the Weyerhaeuser Interest to the
Company, for $700,000,000 in cash. Such purchase and sale will be consummated
simultaneously with, and as a condition to, the consummation of the
transactions contemplated by any Takeover Proposal made by the person who made
the Superior Proposal that gave rise to such termination. In the agreement
entered into by the Company with such person in connection with such
termination, such person must unconditionally guarantee (for the benefit of
Weyerhaeuser and its subsidiaries) the obligations of the Company contained
this paragraph.

  The Merger Agreement provides that if (i) after the date of the Merger
Agreement, any person makes a Takeover Proposal or amends a Takeover Proposal
made prior to the date of the Merger Agreement, (ii) the Offer remains open
until the scheduled expiration date immediately following the date such
Takeover Proposal is made (or such later date as the Offer may be extended to
at the Company's request pursuant to the Merger Agreement), (iii) the Minimum
Condition is not satisfied at the expiration of the Offer and (iv) the Merger
Agreement is terminated pursuant to clause (2)(c) under "Termination of the
Merger Agreement", the Buy Rights, if any, resulting from the MB Transaction
will terminate; provided, however, notwithstanding anything in the Partnership
Agreement to the contrary:


                                      32
<PAGE>

    (A) the Company may exercise the Buy Rights within the 10 day period
  beginning with the date of termination of the Merger Agreement for a "Buy
  Price" of $700,000,000 in cash and otherwise pursuant to the terms of the
  Partnership Agreement; and

    (B) if the Company did not exercise its right under clause (A) above and
  within 12 months following such termination the Company enters into an
  agreement to consummate an Acquisition Proposal, or an Acquisition Proposal
  is consummated, the Company shall purchase the Weyerhaeuser Interest, and
  Weyerhaeuser shall, and shall cause its subsidiaries, to sell the
  Weyerhaeuser Interest to the Company, for $700,000,000 in cash, such
  purchase and sale to be consummated simultaneously with, and as a condition
  to, the consummation of such Acquisition Proposal.

  The Merger Agreement provides that, notwithstanding anything contained in
the Partnership Agreement to the contrary, but subject to this provisions
described in this section, the Company may not exercise the Buy Rights as a
result of the MB Transaction if the Merger Agreement is terminated prior to
the acceptance for payment of Shares pursuant to the Offer:

    (A) in the circumstances contemplated by the two preceding paragraphs;

    (B) pursuant to clause (2)(c) or clause (4) under "Termination of the
  Merger Agreement" following the failure of the condition in paragraph (f)
  of Section 14; or

    (C) pursuant to clause (2)(c) or clause (3) under "Termination of the
  Merger Agreement" following the failure of the condition in paragraph (e)
  of Section 14, because, in either case, (A) other than as disclosed, since
  the date of the most recent audited financial statements included in
  documents filed by the Company with the Commission and prior to the date of
  the Merger Agreement, there shall have occurred any event, change, effect
  or development that, individually or in the aggregate, has had or is
  reasonably likely to have a Material Adverse Effect or (B)(1) any
  representation or warranty of the Company in the Merger Agreement that is
  qualified as to Material Adverse Effect shall not be true and correct as of
  the date of the Merger Agreement or (2) the representations and warranties
  of the Company that are not qualified as to Material Adverse Effect shall
  not be true and correct in all respects as of the date of the Merger
  Agreement if the failure of all such representations and warranties in this
  clause (2) to be true and correct, individually or in the aggregate, is
  materially adverse to the transactions contemplated by the Merger
  Agreement, taken as a whole.

  The Merger Agreement provides that notwithstanding any provision to the
contrary in the Partnership Agreement, if the Merger Agreement is terminated
in accordance with the terms hereof and none of the preceding three paragraphs
is applicable, the 90-day period under the Partnership Agreement during which
the Company may exercise its Buy Rights, if any, in connection with the MB
Transaction shall be deemed to begin to run from the date of such termination
of the Merger Agreement. Except with respect to the running of the 90-day
period, the procedures governing the Buy Rights as set forth in the
Partnership Agreement, to the extent applicable, shall apply.

  Grant of Conditional Option. Pursuant to the Merger Agreement, the Company
has granted to the Purchaser an irrevocable option (the "Option") to purchase
for a price of $42.00 per share (the "Per Share Price") in cash a number of
Common Shares (the "Optioned Shares") equal to the Applicable Amount. The
"Applicable Amount" shall be the number of Common Shares which, when added to
the number of Common Shares owned by Weyerhaeuser and the Purchaser
immediately prior to its exercise of the Option, would result in the Purchaser
owning immediately after its exercise of the Option 90% of the then-
outstanding Common Shares. The Purchaser may exercise the Option only if, at
the time of exercise, Weyerhaeuser, the Purchaser and any other subsidiary of
Weyerhaeuser shall have acquired at least 50.1% of the Fully Diluted Shares
pursuant to the Offer. The Option shall expire if not exercised prior to the
effective time of the Merger. The Per Share Price may, at the election of the
Purchaser, be paid either (i) in cash or (ii) a combination of $1.00 in cash
and a promissory note of Weyerhaeuser in a principal amount equal to $41.00,
which promissory note shall mature in 12 months (and be Prepayable at any time
by Parent without penalty) and shall bear interest at an annual rate of 6.50%
payable at maturity.

                                      33
<PAGE>

  Termination/Amendment of ESOP; Redemption of Company Preferred Stocks;
Repayment of ESOP Loan. If upon consummation of the Offer, the Purchaser owns
a number of Common Shares that, together with the Common Shares that the
Purchaser has the Option to purchase as described under "Grant of Conditional
Option", equals at least 90% of the then-outstanding Common Shares (after
giving effect to the exercise of such Option), then the Company shall take
such action as requested by Weyerhaeuser and permitted by the terms of the
Company Preferred Certificate of Designation and applicable law to terminate
and/or amend the ESOP and to call for redemption all the then-outstanding
Preferred Stock as promptly as practicable after such request by Weyerhaeuser.
As soon as practicable after the date of the Merger Agreement, the Company
shall direct the trustee for the Company's Investment Plan to use any cash
proceeds resulting from the redemption of the Preferred Stock or resulting
from the purchase or exchange of Common Stock (into which Preferred Stock was
converted) for cash pursuant to the Offer or the Merger, in each case, with
respect to shares that have not been allocated to participants or
beneficiaries under the Company's Investment Plan, shall be used to repay any
outstanding amounts under the loan from the Company to the trustee for the
Company's Investment Plan, and shall use its best efforts to take or cause to
be taken such other actions consistent with applicable law to cause the
Trustee to comply with such direction, and the parties agree that any
remaining cash proceeds shall be allocated to participants and beneficiaries
under the Company's Investment Plan in accordance with applicable law.

  The foregoing summary of the Merger Agreement is qualified in its entirety
by reference to the Merger Agreement, a copy of which is filed as Exhibit
(c)(1) to the Schedule 14D-1. The Merger Agreement should be read in its
entirety for a more complete description of the matters summarized above.

 Partnership Agreement

  Substantially all of the current business of the Company is conducted
through the Partnership. In 1991, the Company contributed its North American
engineered lumber products business to the Partnership in exchange for general
and limited partnership interests representing a 51% interest in the
Partnership, and MBA, a wholly-owned subsidiary of MB, contributed all of its
and MB's North American engineered lumber technology and manufacturing
facilities in exchange for a 49% limited partnership interest in the
Partnership.

  The management and control of the Partnership is vested in the Company as
general partner. Under the Partnership Agreement a management board was
established and consists of four members appointed by the Company and three
members appointed by MBA. The Company, as general partner, is required to
consult with the management board with respect to certain matters regarding
the operation of the Partnership. In addition, unanimous approval of the
management board is required to approve certain significant matters, including
distributions of distributable cash to the partners, redemptions of
partnership interests, dissolution or winding up of the Partnership, the
merger or consolidation of the Partnership, and certain other matters
including the encumbrance of assets, incurrence of debt, investments and
capital expenditures by the Partnership.

  The Partnership is to continue for an indefinite term until terminated by
mutual agreement of the partners.

  The Partnership Agreement prohibits each partner from selling, pledging or
otherwise disposing of its interest in the Partnership, without the consent of
the other partner, other than certain permitted transfers to affiliates of a
partner, permitted encumbrances and transfers by a partner that offers the
other partner a right of first refusal.

  The Partnership Agreement specifies certain events of default by a partner
and the remedies available to the nondefaulting partner. Among the "events of
default" under the Partnership Agreement is a change in control of a partner.
The Partnership Agreement states that an event of default will occur if a
partner is "taken over or purchased by a third party or parties resulting in a
change in control compared with those controlling the defaulting partner" as
of September 30, 1991, the date the Partnership became effective. The
Partnership Agreement defines "control" as " (i) the right to exercise a
majority of the votes which may be cast at a general meeting of a corporation;
and (ii) the right to elect or appoint, directly or indirectly, a majority of
the directors of

                                      34
<PAGE>

a corporation or other persons who have the right to manage or supervise the
management of the affairs and business of the corporation."

  On November 1, 1999, MBA became an indirect wholly owned subsidiary of
Weyerhaeuser. As described in Section 11, the Company has asserted that the
consummation of the MB Transaction constituted a change of control of MBA
within the meaning of the Partnership Agreement that gives the Company the
ability to exercise the rights under the Purchase Agreement described below.
Weyerhaeuser has asserted that the consummation of the MB Transaction did not
constitute such a change of control of MBA and that the Company does not have
any of such rights. See "The Merger Agreement--Waiver Under Partnership
Agreement" above.

  The Purchase Agreement provides that if a change in control of a partner
(the "defaulting partner") occurs, the other partner (the "nondefaulting
partner") may initiate one of the following procedures within 90 days of the
change in control.

    (1) Buy Procedure: The nondefaulting partner may purchase all of the
  defaulting partner's interest in the Partnership at a purchase price equal
  to the value of the business of the Partnership represented by each
  partner's interest, as determined by two investment bankers selected by the
  partners. If they are unable to agree on value, the values determined by
  each of them will be submitted to a third investment banker, which will
  make a final determination by choosing between the two values submitted.
  The value to be determined by the investment bankers is the value of the
  defaulting partner's interest without the premium, if any, attributable to
  the change in control of the defaulting partner. The nondefaulting partner
  then has 30 days after the determination of the purchase price to exercise
  its right to buy the defaulting partner's interest and the closing of such
  purchase is to occur on the 90th business day following such exercise.

    (2) Sell Procedure: The nondefaulting partner may sell all of its
  interest in the Partnership to the defaulting partner at a sale price equal
  to the value determined by investment bankers as described under (1) above,
  plus the premium, if any, attributable to the change in control of the
  defaulting partner. If the sale procedure is implemented, the defaulting
  partner must purchase the nondefaulting partner's interest within 90
  business days of the determination of the sale price.

    (3) Mandatory Buy/Sell Procedure: The nondefaulting partner may give the
  defaulting partner notice containing an offer to purchase all of the
  interest held by the defaulting partner and an offer to sell all of the
  interest held by the nondefaulting partner. The offer to buy and the offer
  to sell will be at the same price, adjusted for the percentage represented
  by each partner's interest. If the defaulting partner does not accept
  either offer within 30 days after receipt of notice, it will be deemed to
  have accepted an offer by the nondefaulting partner to purchase all the
  defaulting partner's interest in the Partnership.

  See "The Merger Agreement--Waiver Under Partnership Agreement" above for a
description of certain changes to rights of the partners under the Partnership
Agreement agreed in connection with the Merger Agreement.

  The summary of certain provisions of the Partnership Agreement above does
not purport to be a complete description of the terms of the Partnership
Agreement and is qualified by reference to the Partnership Agreement which is
filed as an Exhibit to the Form 8-K filed by the Company with the Commission
on September 30, 1991.

 Standstill Agreement

  In connection with the formation of the Partnership, MB and the Company
entered into an agreement dated as of October 1, 1991 (the "Standstill
Agreement"). The Standstill Agreement prohibits MB and entities controlled by
it (the "MB Group"), either alone or in concert with others, from (a)
acquiring voting securities of the Company, with certain exceptions including
the acquisition of voting securities in response to a tender offer by a third
party for the Company's voting securities or in the event that a third party
acquires voting securities of the Company representing more than 40% of the
total voting power of all outstanding voting securities, (b) participating in
a solicitation of holders of voting securities of the Company or otherwise
attempting to influence such holders unless approved by the Board of Directors
of the Company, or (c) participating in arrangements

                                      35
<PAGE>

with respect to the voting, holding or acquisition of voting securities of the
Company or any matter relating to the control of the Company. The Standstill
Agreement also contains provisions for the disposition of voting securities
that may be owned or acquired by members of the MB Group. The Standstill
Agreement provides that it shall continue in effect until six years after the
dissolution of the Partnership.

 Confidentiality Agreement

  Weyerhaeuser and the Company entered into a Confidentiality Agreement on
November 16, 1999. Pursuant to the Confidentiality Agreement, Weyerhaeuser
agreed to treat confidentially any information that the Company or its agents
or advisors furnish to Weyerhaeuser or its representatives, subject to
exceptions for applicable law and deposition, interrogatory, request for
documents, subpoena, civil investigative demand or similar process.
Weyerhaeuser also agreed that, for the period ending six months from the date
of the Confidentiality Agreement, it will not solicit for employment any
person who is currently employed in a management position with the Company.

 Plans for the Company

  Currently, Weyerhaeuser anticipates that, following the Merger, the Company
will operate as a separate operating division of Weyerhaeuser under the
Company's current management team. Weyerhaeuser expects that the Company will
continue to own its assets and conduct its business as it currently does,
although the Company's sales and marketing functions will be integrated into
and rationalized with Weyerhaeuser's. Weyerhaeuser also currently expects to
leverage its staff to provide greater efficiencies in staff and
logistical/purchasing support for the Company's operations.

 Appraisal Rights

  The holders of Shares do not have appraisal rights as a result of the Offer.
However, if the Merger is consummated, holders of Shares at the effective time
of the Merger will have certain rights pursuant to the provisions of Section
262 of the DGCL ("Section 262") to dissent and demand appraisal of their
Shares. Under Section 262, dissenting stockholders who comply with the
applicable statutory procedures will be entitled to receive a judicial
determination of the fair value of their Shares (exclusive of any element of
value arising from the accomplishment or expectation of the Merger) and to
receive payment of such fair value in cash, together with a fair rate of
interest, if any. Any such judicial determination of the fair value of Shares
could be based upon factors other than, or in addition to, the price per Share
to be paid in the Merger or the market value of the Shares. The value so
determined could be more or less than the price per Share to be paid in the
Merger.

  The foregoing summary of Section 262 does not purport to be complete and is
qualified in its entirety by reference to Section 262. Failure to follow the
steps required by Section 262 for perfecting appraisal rights may result in
the loss of such rights.

 Going Private Transactions

  The Commission has adopted Rule 13e-3 under the Exchange Act, which is
applicable to certain "going private" transactions. The Purchaser does not
believe that Rule 13e-3 will be applicable to the Merger unless the Merger is
consummated more than one year after the termination of the Offer. If
applicable, Rule 13e-3 requires, among other things, that certain financial
information concerning the fairness of the Merger and the consideration
offered to minority stockholders in the Merger be filed with the Commission
and disclosed to stockholders prior to the consummation of the Merger.

  Except as otherwise described in this Offer to Purchase, the Purchaser and
Weyerhaeuser have no current plans or proposals that would relate to, or
result in, an extraordinary corporate transaction involving the Company, such
as a merger, reorganization or liquidation involving the Company or any of its
subsidiaries, a sale or transfer of a material amount of assets of the Company
or any of its subsidiaries, any change in the present

                                      36
<PAGE>

Board of Directors or management of the Company, including, but not limited
to, any plans or proposals to change the number or term of directors or to
fill any existing vacancies on the Board of Directors, any material change in
the Company's present capitalization or dividend policy, any other material
change in the Company's corporate structure or business, causing a class of
securities of the Company to be delisted from a national securities exchange
or to cease to be authorized to be quoted in an inter-dealer quotation system
of a registered national securities association or a class of equity
securities of the Company becoming eligible for termination of registration
pursuant to Section 12(g)(4) of the Exchange Act.

13. Dividends and Distributions

  Pursuant to the terms of the Merger Agreement, the Company is prohibited
from taking any of the actions described in the two succeeding paragraphs, and
nothing herein shall constitute a waiver by the Purchaser or Weyerhaeuser of
any of its rights under the Merger Agreement or a limitation of remedies
available to the Purchaser or Weyerhaeuser for any breach of the Merger
Agreement, including termination thereof.

  If the Company (a) splits, combines or otherwise changes the Shares or its
capitalization, (b) acquires or otherwise causes a reduction in the number of
outstanding Shares or other securities or (c) issues or sells additional
Shares, shares of any other class of Capital Stock, other voting securities or
any securities convertible into, or rights, warrants or options, conditional
or otherwise, to acquire any of the foregoing, other than Shares issued
pursuant to the exercise of outstanding Company Employee Stock Options, then,
subject to the provisions described in Section 14, the Purchaser may, subject
to the terms of the Merger Agreement (which restricts the Purchaser from
taking certain actions without the consent of the Company) make such
adjustments as it deems appropriate in the Offer Price and other terms of the
Offer, including without limitation, the number or type of securities offered
to be purchased.

  If, on or after November 23, 1999, the Company declares or pays any cash
dividend on the Shares or other distribution on the Shares, or issues with
respect to the Shares any additional Shares, shares of any other class of
capital stock, other voting securities or any securities convertible into, or
rights, warrants or options, conditional or otherwise, to acquire, any of the
foregoing, payable or distributable to stockholders of record on a date prior
to the transfer of the Shares purchased pursuant to the Offer to the Purchaser
or its nominee or transferee on the Company's stock transfer records (other
than the dividends permitted under the Merger Agreement as described in clause
(b)(i) under the heading "The Merger Agreement--Conduct of Business" in
Section 12), then, subject to the provisions described in Section 14 and
subject to the terms of the Merger Agreement (which restrict the Purchaser
from taking certain actions without the consent of the Company), (a) the Offer
Price may be reduced by the amount of any such cash dividend or cash
distribution and (b) the whole of any such noncash dividend, distribution or
issuance to be received by the tendering stockholders will (i) be received and
held by the tendering stockholders for the account of the Purchaser and will
be required to be promptly remitted and transferred by each tendering
stockholder to the Depositary for the account of the Purchaser, accompanied by
appropriate documentation of transfer, or (ii) at the direction of the
Purchaser, be exercised for the benefit of the Purchaser, in which case the
proceeds of such exercise will promptly be remitted to the Purchaser. Pending
such remittance and subject to applicable law, the Purchaser will be entitled
to all rights and privileges as owner of any such noncash dividend,
distribution, issuance or proceeds and may withhold the entire Offer Price or
deduct from the Offer Price the amount or value thereof, as determined by the
Purchaser in its sole discretion.

14. Certain Conditions of the Offer

  Notwithstanding any other term of the Offer or the Merger Agreement, the
Purchaser will not be required to accept for payment or, subject to any
applicable rules and regulations of the Commission, including Rule 14e-l(c)
under the Exchange Act (relating to the Purchaser's obligation to pay for or
return tendered Shares promptly after the termination or withdrawal of the
Offer), to pay for any Shares tendered pursuant to the Offer unless (i) the
Minimum Condition shall have been satisfied and (ii) (A) any waiting period
under the HSR Act applicable to the purchase of Shares pursuant to the Offer
shall have expired or been terminated, (B) any waiting period under the
Canadian Competition Act applicable to the purchase of Shares pursuant to the
Offer shall have

                                      37
<PAGE>

expired or been terminated and/or an advance ruling certificate pursuant to
the Canadian Competition Act or, in the alternative of an advance ruling
certificate, a no-action letter from the Commissioner of Competition, related
thereto shall have been received and (C) any consents, approvals and filings
under any foreign antitrust law, the absence of which would prohibit the
consummation of the Offer, shall have been obtained or made. For purposes of
the Minimum Condition, the Merger Agreement defines "Fully Diluted Shares" as
all outstanding securities entitled generally to vote in the election of
directors of the Company on a fully diluted basis, after giving effect to the
exercise or conversion of all options, rights and securities exercisable or
convertible into such voting securities, other than potential dilution
attributable to the Rights and the Option. Furthermore, notwithstanding any
other term of the Offer, the Purchaser may, subject to the terms of the Merger
Agreement, amend the Offer or postpone the acceptance for payment of or
payment for tendered Shares if, at any time on or after the date of the Merger
Agreement and before the expiration of the Offer, any of the following
conditions exists:

    (a) there shall be pending any suit, action or proceeding by any
  Governmental Entity that has a reasonable likelihood of success, (i)
  challenging the acquisition by Weyerhaeuser or the Purchaser of any Shares,
  seeking to restrain or prohibit the making or consummation of the Offer or
  the Merger or seeking to obtain from the Company, Weyerhaeuser or the
  Purchaser any damages that are material in relation to the Company and its
  subsidiaries taken as whole as a result of the transactions contemplated by
  the Merger Agreement, (ii) seeking to prohibit or limit in any material
  respect the ownership or operation by the Company, Weyerhaeuser or any of
  their respective subsidiaries of any material portion of the business or
  assets of the Company, Weyerhaeuser or any of their respective
  subsidiaries, or to compel the Company, Weyerhaeuser or any of their
  respective subsidiaries to dispose of or hold separate any material portion
  of the business or assets of the Company, Weyerhaeuser or any of their
  respective subsidiaries, as a result of the Offer and the Merger, (iii)
  seeking to impose limitations on the ability of Weyerhaeuser or the
  Purchaser to acquire or hold, or exercise full rights of ownership of, any
  Shares, including the right to vote the Shares purchased by it on all
  matters properly presented to the stockholders of the Company or (iv)
  seeking to prohibit Weyerhaeuser or any of its subsidiaries from
  controlling in any material respect the business or operations of the
  Company and its subsidiaries;

    (b) any statute, rule, regulation, legislation, interpretation, judgment,
  order or injunction shall be enacted, entered, enforced, promulgated or
  issued with respect to, or deemed applicable to, or any consent or approval
  withheld with respect to (i) Weyerhaeuser, the Company or any of their
  respective subsidiaries or (ii) the Offer, the Merger or any other
  transaction contemplated by the Merger Agreement, in each case, by any
  Governmental Entity that is reasonably likely to result, directly or
  indirectly, in any of the consequences referred to in paragraph (a) above;

    (c) except as disclosed, since the date of the Merger Agreement there
  shall have occurred any event, change, effect or development that,
  individually or in the aggregate, has had or is reasonably likely to have,
  a Material Adverse Effect;

    (d) there shall have occurred and continued to exist (i) any general
  suspension of trading in, or limitation on prices for, securities on any
  national securities exchange or in the over-the-counter market in the
  United States (excluding any suspension or limitations resulting from
  physical damage or interference with such exchange not related to market
  conditions), (ii) a decline of at least 30% in the Dow Jones Industrial
  Average, (iii) a declaration of a banking moratorium or any suspension of
  payments in respect of banks in the United States, (iv) any mandatory
  limitation by any Governmental Entity on, or other event that materially
  and adversely affects, the extension of credit by banks or other lending
  institutions in the United States, (v) a commencement of a war or armed
  hostilities or other national or international calamity directly or
  indirectly involving the United States or (vi) in the case of any of the
  foregoing existing on the date of the Merger Agreement, a material
  acceleration or worsening thereof;

    (e) (i) any representation and warranty of the Company in the Merger
  Agreement that is qualified as to Material Adverse Effect shall not be true
  and correct as of the date of the Merger Agreement or as of such time,
  except to the extent such representation and warranty expressly relates to
  an earlier date (in which case on and as of such earlier date) and (ii) the
  representations and warranties of the Company that are not qualified as to
  Material Adverse Effect shall not be true and correct in all respects as of
  the date of the

                                      38
<PAGE>

  Merger Agreement, or as of such time, except to the extent such
  representations and warranties expressly relate to an earlier date (in
  which case on and as of such earlier date) if the failure of all such
  representations and warranties in this clause (ii) to be true and correct,
  in aggregate, is materially adverse to the transactions contemplated by the
  Merger Agreement, taken as a whole;

    (f) the Company shall have failed to perform in any material respect any
  obligation or to comply in any material respect with any agreement or
  covenant of the Company to be performed or complied with by it under the
  Merger Agreement; or

    (g) the Merger Agreement shall have been terminated in accordance with
  its terms;

which, in the sole judgment of the Purchaser or Weyerhaeuser, in any such
case, and regardless of the circumstances giving rise to any such condition
(including any action or inaction by Weyerhaeuser or any of its affiliates not
otherwise required by the Merger Agreement), makes it inadvisable to proceed
with such acceptance for payment or payment.

  The foregoing conditions are for the sole benefit of the Purchaser and
Weyerhaeuser and may be asserted by the Purchaser or Weyerhaeuser regardless
of the circumstances giving rise to such condition or may be waived by the
Purchaser and Weyerhaeuser in whole or in part at any time and from time to
time in their sole discretion. The failure by Weyerhaeuser, the Purchaser or
any other affiliate of Weyerhaeuser at any time to exercise any of the
foregoing rights shall not be deemed a waiver of any such right, the waiver of
any such right with respect to particular facts and circumstances shall not be
deemed a waiver with respect to any other facts and circumstances and each
such right shall be deemed an ongoing right that may be asserted at any time
and from time to time.

15. Certain Legal Matters

  Except as described in this Section 15, based on a review of publicly
available filings made by the Company with the Commission and other publicly
available information concerning the Company and discussions of
representatives of Weyerhaeuser with representatives of the Company, none of
the Purchaser, Weyerhaeuser or the Company is aware of any license or
regulatory permit that appears to be material to the business of the Company
and its subsidiaries, taken as a whole, that might be adversely affected by
the Purchaser's acquisition of Shares (and the indirect acquisition of the
stock of the Company's subsidiaries) as contemplated herein or of any approval
or other action by any Governmental Entity that would be required or desirable
for the acquisition or ownership of Shares by the Purchaser as contemplated
herein. Should any such approval or other action be required or desirable, the
Purchaser and Weyerhaeuser currently contemplate that such approval or other
action will be sought, except as described below under "State Takeover Laws".
While (except as otherwise expressly described in this Section 15) the
Purchaser does not presently intend to delay the acceptance for payment of or
payment for Shares tendered pursuant to the Offer pending the outcome of any
such matter, there can be no assurance that any such approval or other action,
if needed, would be obtained or would be obtained without substantial
conditions or that failure to obtain any such approval or other action might
not result in consequences adverse to the Company's business or that certain
parts of the Company's business might not have to be disposed of if such
approvals were not obtained or such other actions were not taken or in order
to obtain any such approval or other action. If certain types of adverse
action are taken with respect to the matters discussed below, the Purchaser
could decline to accept for payment or pay for any Shares tendered. See
Section 14 for a description of certain conditions to the Offer.

  State Takeover Laws. A number of states throughout the United States have
enacted takeover statutes that purport, in varying degrees, to be applicable
to attempts to acquire securities of corporations that are incorporated or
have assets, stockholders, executive offices or places of business in such
states. In Edgar v. MITE Corp., the Supreme Court of the United States held
that the Illinois Business Takeover Act, which involved state securities laws
that made the takeover of certain corporations more difficult, imposed a
substantial burden on interstate commerce and therefore was unconstitutional.
In CTS Corp. v. Dynamics Corp. of America, however, the Supreme Court of the
United States held that a state may, as a matter of corporate law and, in
particular, those laws concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs

                                      39
<PAGE>

of a target corporation without prior approval of the remaining stockholders,
provided that such laws were applicable only under certain conditions.
Subsequently, a number of federal courts ruled that various state takeover
statutes were unconstitutional insofar as they apply to corporations
incorporated outside the state of enactment.

  Section 203 of the DGCL, in general, prohibits a Delaware corporation such
as the Company from engaging in a "Business Combination" (defined as a variety
of transactions including, mergers with an "Interested Stockholder") (defined
generally as a person that is the beneficial owner of 15% or more of a
corporation's outstanding voting stock) for a period of three years following
the time that such person became an Interested Stockholder unless, among other
things, prior to the time such person became an Interested Stockholder, the
board of directors of the corporation approved either the Business Combination
or the transaction that resulted in the stockholder becoming an Interested
Stockholder. The Board of Directors of the Company has taken action sufficient
to render Section 203 and Article Tenth of the Company Charter inapplicable
(a) to Weyerhaeuser and the Purchaser solely by reason of their entering into
the Merger Agreement or consummating the Offer or the Merger or the grant or
exercise of the Option and (b) to the Offer, the Merger and certain other
transactions contemplated by the Merger Agreement, assuming the accuracy of
Weyerhaeuser's representations that neither Weyerhaeuser nor the Purchaser
beneficially owns any Shares and that neither Weyerhaeuser nor the Purchaser
is an Interested Stockholder of the Company.

  Based on information supplied by the Company, the Purchaser does not believe
that any other state takeover statutes or similar laws purport to apply to the
Offer or the Merger. In particular, the Company has not elected to be subject
to the control share acquisition provisions and the business combination
provisions of the State of Idaho. Neither the Purchaser nor Weyerhaeuser has
currently complied with any state takeover statute or regulation. The
Purchaser reserves the right to challenge the applicability or validity of any
state law purportedly applicable to the Offer or the Merger and nothing in
this Offer to Purchase or any action taken in connection with the Offer or the
Merger is intended as a waiver of such fight. If it is asserted that any state
takeover statute is applicable to the Offer or the Merger and an appropriate
court does not determine that it is inapplicable or invalid as applied to the
Offer or the Merger, the Purchaser might be required to file certain
information with, or to receive approvals from, the relevant state
authorities, and the Purchaser might be unable to accept for payment or pay
for Shares tendered pursuant to the Offer, or be delayed in consummating the
Offer or the Merger. In such case, the Purchaser may not be obligated to
accept payment or pay for any Shares tendered pursuant to the Offer. See
Section 14.

  Antitrust. Under the provisions of the HSR Act applicable to the Offer, the
acquisition of Shares under the Offer may be consummated after the expiration
of a 15-calendar day waiting period commenced by the filing by Weyerhaeuser of
a Notification and Report Form with respect to the Offer, unless Weyerhaeuser
receives a request for additional information or documentary material from the
Antitrust Division or the FTC or earlier if early termination of the waiting
period is granted. Weyerhaeuser expects to make such filing in the near
future. If, within the initial 15-day waiting period, either the Antitrust
Division or the FTC requests additional information or material from
Weyerhaeuser concerning the Offer, the waiting period will be extended and
would expire at 11:59 p.m., New York City time, on the tenth calendar day
after the date of substantial compliance by Weyerhaeuser with such request,
unless earlier terminated. Only one extension of the waiting period pursuant
to a request for additional information is authorized by the HSR Act.
Thereafter, such waiting period may be extended only by court order or with
the consent of Weyerhaeuser. In practice, complying with a request for
additional information or material can take a significant amount of time. In
addition, if the Antitrust Division or the FTC raises substantive issues in
connection with a proposed transaction, the parties frequently engage in
negotiations with the relevant governmental agency concerning possible means
of addressing those issues and may agree to delay consummation of the
transaction while such negotiations continue. Expiration or termination of the
applicable waiting period under the HSR Act is a condition to the Purchaser's
obligation to accept for payment and pay for Shares tendered pursuant to the
Offer. Pursuant to the HSR Act, Weyerhaeuser will request early termination of
the applicable waiting period, but there can be no assurance that the waiting
period will be terminated early.

                                      40
<PAGE>

  The Merger will not require an additional filing under the HSR Act if the
Purchaser owns 50% or more of the outstanding Shares at the time of the Merger
or if the Merger occurs within one year after the HSR Act waiting period
applicable to the Offer expires or is terminated.

  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed
acquisition of the Company. At any time before or after the Purchaser's
acquisition of Shares pursuant to the Offer, the Antitrust Division or the FTC
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or the consummation of the Merger or seeking the
divestiture of Shares acquired by the Purchaser or the divestiture of
substantial assets of the Company or its subsidiaries or Weyerhaeuser or its
subsidiaries. Private parties and states may also bring legal action under the
antitrust laws under certain circumstances. Although Weyerhaeuser currently
owns a 49% interest in the Partnership, there can be no assurance that a
challenge to the Offer on antitrust grounds will not be made or, if such a
challenge is made, of the result thereof.

  Canadian Competition Act.  Under the provisions of the Competition Act
(Canada) (the "Canadian Act"), the acquisition of Shares under the Offer may
be consummated after the expiration of a 7-calendar day waiting period
commenced by the filing by Weyerhaeuser of a short-form premerger filing under
the Canadian Act with respect to the Offer, unless Weyerhaeuser receives a
request to complete a long-form filing prior to the expiration of the 7-
calendar day waiting period, in which case a long-form filing must be made,
after completion of which a 21-day calendar day waiting period is mandated.
These waiting periods are expected to be doubled by legislative changes that
may be implemented in respect of premerger notification filings under the
Canadian Act made after mid-December 1999. Weyerhaeuser expects to make a
short-form filing under the Canadian Act in the near future. Before or after
the waiting periods referred to above have expired, upon application by the
Commissioner of Competition under the Canadian Act (the "Commissioner") which
certifies that in the Commissioner's opinion more time is required to complete
his inquiry into the Offer, the Canadian Competition Tribunal may issue an
interim order forbidding any person from, among other things, completing the
Offer. The interim order shall not have a term longer than thirty days; on
further application by the Commissioner that he is unable to complete an
inquiry within the period specified in the order because of circumstances
beyond his control, the Canadian Competition Tribunal may extend the duration
of the order to a day not more than sixty days after the order takes effect.
In the course of his inquiry, the Commissioner may request additional
information. In practice, complying with such requests can take a significant
amount of time. In addition, if the Commissioner raises substantive issues in
connection with a proposed transaction, the parties frequently engage in
negotiations with the Commissioner concerning possible means of addressing
those issues and may agree to delay consummation of the transaction while such
negotiations continue. Expiration of the applicable waiting periods under the
Canadian Act is a condition to the Purchaser's obligation to accept for
payment and pay for Shares tendered pursuant to the Offer.

  The Merger will not require an additional filing under the Canadian Act if
the Purchaser owns more than 50% of the outstanding Shares at the time of the
Merger or if the Merger is completed within one year after the making of the
premerger notification filings under the Canadian Act.

  The Commissioner frequently scrutinizes the legality under the Canadian Act
of transactions such as the Purchaser's proposed acquisition of the Company.
At any time before or after the Purchaser's acquisition of Shares pursuant to
the Offer, the Commissioner could take such action under the Canadian Act as
he deems necessary or desirable in the public interest, including seeking to
enjoin the purchase of Shares pursuant to the Offer or the consummation of the
Merger or seeking the divestiture of Shares acquired by the Purchaser or the
divestiture of substantial assets of the Company or its subsidiaries or
Weyerhaeuser or its subsidiaries. There can be no assurance that a challenge
to the Offer under the Canadian Act will not be made or, if such a challenge
is made, of the result thereof.

  Other Foreign Laws. The Company and certain of its subsidiaries conduct
business in several foreign countries where regulatory filings or approvals
may be required or desirable in connection with the consummation of the Offer.
Certain of such filings or approvals, if required or desirable, may not be
made or

                                      41
<PAGE>

obtained prior to the expiration of the Offer. The Purchaser is seeking
further information regarding the applicability of any such laws and currently
intends to take such action as may be required or desirable. If any foreign
Governmental Entity takes any action prior to the completion of the Offer that
might have certain adverse effects, the Purchaser will not be obligated to
accept for payment or pay for any Shares tendered. See Section 14.

16. Fees and Expenses

  Morgan Stanley is acting as Dealer Manager in connection with the Offer and
is providing certain financial advisory services to the Purchaser and
Weyerhaeuser in connection with the Offer. Pursuant to an engagement letter
dated November 15, 1999, between Weyerhaeuser and Morgan Stanley, advisory
fees of $875,000 are currently payable to Morgan Stanley. An additional fee of
$2,085,000 will be payable to Morgan Stanley in the event the Offer is
consummated. Weyerhaeuser has also agreed to reimburse Morgan Stanley for its
out-of-pocket expenses, including the fees and expenses of its counsel and any
other advisor retained by Morgan Stanley in connection with its engagement,
and to indemnify Morgan Stanley and certain related persons against certain
liabilities and expenses, including certain liabilities under federal
securities laws.

  In the ordinary course of its business, Morgan Stanley engages in securities
trading, market-making and brokerage activities and may, at any time, hold
long or short positions and may trade or otherwise effect transactions in debt
or equity securities or senior loans of the Company.

  The Purchaser and Weyerhaeuser have retained Georgeson Shareholder
Communications Inc. to act as the Information Agent and the First Chicago
Trust Company of New York to serve as the Depositary in connection with the
Offer. The Information Agent and the Depositary each will receive reasonable
and customary compensation for their services, be reimbursed for certain
reasonable out-of-pocket expenses and be indemnified against certain
liabilities and expenses in connection therewith, including certain
liabilities and expenses under the U.S. federal securities laws.

  Neither the Purchaser nor Weyerhaeuser will pay any fees or commissions to
any broker or dealer or other person (other than the Dealer Manager and the
Information Agent) in connection with the solicitation of tenders of Shares
pursuant to the Offer. Brokers, dealers, banks and trust companies will be
reimbursed by the Purchaser upon request for customary mailing and handling
expenses incurred by them in forwarding material to their customers.

17. Miscellaneous

  The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of
such jurisdiction. Neither the Purchaser nor Weyerhaeuser is aware of any
jurisdiction in which the making of the Offer or the acceptance thereof would
not be in compliance with the laws of such jurisdiction. To the extent the
Purchaser or Weyerhaeuser becomes aware of any state law that would limit the
class of offerees in the Offer, the Purchaser will amend the Offer and,
depending on the timing of such amendment, if any, will extend the Offer to
provide adequate dissemination of such information to holders of Shares prior
to the expiration of the Offer. In any jurisdiction the securities, blue sky
or other laws of which require the Offer to be made by a licensed broker or
dealer, the Offer is being made on behalf of the Purchaser by the Dealer
Manager or one or more registered brokers or dealers licensed under the laws
of such jurisdiction.

  No person has been authorized to give any information or to make any
representation on behalf of the Purchaser or Weyerhaeuser not contained herein
or in the Letter of Transmittal and, if given or made, such Information or
representation must not be relied upon as having been authorized.

  The Purchaser and Weyerhaeuser have filed with the Commission the Schedule
14D-1 pursuant to Rule 14d-3 under the Exchange Act together with exhibits,
furnishing certain additional information with respect to the Offer, and may
file amendments thereto. In addition, the Company has filed the Schedule 14D-9
pursuant to

                                      42
<PAGE>

Rule 14d-9 under the Exchange Act, together with exhibits, setting forth its
recommendation with respect to the Offer and the reasons for such
recommendation and furnishing certain additional related information. Such
Schedules and any amendments thereto, including exhibits, should be available
for inspection and copies should be obtainable in the manner set forth in
Section 8 (except that such material will not be available at the regional
offices of the Commission) .

          SECTION 1.01.  The Offer.  (a)  Subject to the conditions of this

Agreement, as promptly as practicable but in no event later than five business
days after the date of this Agreement, Sub shall, and Parent shall cause Sub to,
commence the Offer within the meaning of the applicable rules and regulations of
the Securities and Exchange Commission (the "SEC").  The obligation of Sub to,
                                             ---
and of Parent to cause Sub to, commence the Offer and accept for payment, and
pay for, any shares of Company Capital Stock tendered pursuant to the Offer are
subject to the conditions set forth in Exhibit A (any of which may be waived by
Sub, in its sole discretion, provided that, without the consent of the Company,
                             --------
Sub may not waive the Minimum Tender Condition (as defined in Exhibit A)) and to
the other conditions in this Agreement.  The initial expiration date of the
Offer shall be January 5, 2000.  Sub expressly reserves the right to modify the

payable in the Offer or (vii) otherwise amend the Offer in any manner materially
adverse to holders of Company Capital Stock.  Notwithstanding the foregoing, Sub
may, without the consent of the Company, (i) extend the Offer, if, at the
scheduled expiration date of the Offer, any of the conditions to Sub's
obligation to purchase shares of Company Capital Stock are not satisfied, until
such time as such conditions are satisfied or waived, (ii) extend the Offer for
any period required by any rule, regulation, interpretation or position of the
SEC or the staff thereof applicable to the Offer and (iii) extend the Offer for
any reason for a period (a "Parent Extension Period") of not more than 10
                            -----------------------
business days beyond the latest expiration date that would otherwise be
permitted under clause (i) or (ii) of this sentence or that results from an
extension of the Offer requested by the Company pursuant to the next sentence;

provided, however, that if Sub extends the Offer pursuant to clause (iii) of
- --------  -------
this sentence, it shall waive during any such Parent Extension Period all
conditions of the Offer set forth in Exhibit A other than (x) the Minimum Tender
Condition and (y) the condition in paragraph (b) of Exhibit A solely to the
extent Parent and Sub would violate any Applicable Law (as defined in Section
3.05(a)) or Judgment (as defined in
<PAGE>

                                                                               4

Section 3.05(a)) in purchasing shares of Company Common Stock pursuant to the
Offer. If any of the conditions of the Offer set forth in Exhibit A (other than
the Minimum Tender Condition) is not satisfied or waived on any scheduled
expiration date of the Offer, then, if requested by the Company, Sub shall
extend the Offer one or more times (the period of each such extension to be
determined by Sub) for up to 30 days in the aggregate for all such extensions,
provided that at the time of such extension any such condition is reasonably
capable of being satisfied. On the terms and subject to the conditions of the
Offer and this Agreement, Sub shall, and Parent shall cause Sub to, pay for all
shares of Company Capital Stock validly tendered and not withdrawn pursuant to
the Offer that Sub becomes obligated to purchase pursuant to the Offer as soon
as practicable after the expiration of the Offer.

          (b)  On the date of commencement of the Offer, Parent and Sub shall
file with the SEC a Tender Offer Statement on Schedule 14D-1 with respect to the
Offer, which shall contain an offer to purchase and a related letter of
transmittal and summary advertisement (such Schedule 14D-1 and the documents
included therein pursuant to which the Offer will be made, together with any
supplements or amendments thereto, the "Offer Documents").  Each of Parent, Sub
                                        ---------------
and the Company shall promptly correct any information provided by it for use in
the Offer Documents if and to the extent that such information shall have become
false or misleading in any material respect, and each of Parent and Sub shall
take all steps necessary to amend or supplement the Offer Documents and to cause
the Offer Documents as so amended or supplemented to be filed with the SEC and
to be disseminated to the Company's stockholders, in each case, as and to the
extent required by applicable Federal securities laws.  Parent and Sub shall
provide the Company and its counsel with any comments Parent, Sub or their
counsel may receive from the SEC or its staff with respect to the Offer
Documents promptly after the receipt of such comments.

          SECTION 1.02.  Company Actions.  (a)  The Company hereby approves of

Section 3.04(b) and shall mail the

Schedule 14D-9 to the holders of Company Capital Stock. Each of the Company,
Parent and Sub shall promptly correct any information provided by it for use in
the Schedule 14D-9 if and to the extent that such information shall have become
false or misleading in any material respect, and the Company shall take all
steps necessary to amend or supplement the Schedule 14D-9 and to cause the
Schedule 14D-9 as so amended or supplemented to be filed with the SEC and
disseminated to the Company's stockholders, in each case, as and to the extent
required by applicable Federal securities laws. The Company shall provide Parent
and its counsel with any comments the Company or its counsel may receive from
the SEC or its staff with respect to the Schedule 14D-9 promptly after the
receipt of such comments.

          (c)  In connection with the Offer, the Company shall cause its
transfer agent to promptly furnish Sub with mailing labels containing the names
and addresses of the record holders of Company Capital Stock as of a recent date
and of those persons becoming record holders subsequent to such date, together
with copies of all lists of stockholders, security position listings and
computer files and all other information in the Company's possession or control
regarding the beneficial owners of Company Capital Stock, and shall furnish to
Sub such information and assistance (including updated lists of stockholders,
security position listings and computer files) as Parent may reasonably request
in communicating the Offer to the Company's stockholders.  Subject to the
requirements of Applicable Law, and, except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the transactions contemplated by this Agreement, Parent and Sub shall hold in
confidence the information contained in any such labels, listings and files,
shall use such information only in connection with the Offer and the Merger,
and, if this Agreement shall be terminated, shall, upon request, deliver to the
Company all copies of such information then in their possession.

          SECTION 1.03.  The Merger.  On the terms and subject to the conditions
                         -----------
set forth in this Agreement, and in accordance with the Delaware General
Corporation Law (the "DGCL"), Sub shall be merged with and into the Company at

                                   ---------------------
foregoing, Parent may elect, at any time prior to the

merge the Company with and into Sub; provided, however, that the Company shall
                                     --------  -------
not be deemed to have breached any of its representations, warranties or
covenants set forth in this Agreement solely by reason of such election. In such
event, the parties shall execute an appropriate amendment to this Agreement in
order to reflect the foregoing. At the election of Parent, any direct or
indirect subsidiary of Parent may be substituted for Sub as a constituent
corporation in the Merger. In such event, the parties shall execute an
appropriate amendment to this Agreement in order to reflect the foregoing.

          SECTION 1.04.  Closing.  The closing (the "Closing") of the Merger
                         --------                    -------

parties) of the conditions set forth in Section 7.01, or as soon as practicable
after all the conditions set forth in Section 7.01 have been satisfied (or, to
the extent permitted by Applicable Law, waived by the parties entitled to the
benefits thereof), or at such other place, time and date as shall be agreed in
writing between Parent and the Company.  The date on which the Closing occurs is
referred to in this Agreement as the "Closing Date".
                                      ------------

          SECTION 1.05.  Effective Time.  Prior to the Closing, Parent shall
                         ---------------
prepare, and on the Closing Date or as soon as practicable thereafter, Parent
shall file with the Secretary of State of the State of Delaware, a certificate
of merger or other appropriate documents (in any such case, the "Certificate of
                                                                 --------------
Merger") executed in accordance with the relevant provisions of the DGCL, and
- ------
shall make all other filings or recordings required under the DGCL.  The Merger
shall become effective at such time as the Certificate of Merger is duly filed
with such Secretary of State, or at such other time as Parent and the Company
shall agree and specify in the Certificate of Merger (the time the Merger
becomes effective being the "Effective Time").
                             --------------

          SECTION 1.06.  Effects.  The Merger shall have the effects set forth
                         --------
in Section 259 of the DGCL.

          SECTION 1.07.  Certificate of Incorporation and By-laws.  (a)  The

(i) delete Articles Tenth and Eleventh thereof; and (ii) amend paragraph (a) of

          (b)  The By-laws of Sub as in effect immediately prior to the
Effective Time shall be the By-laws of the Surviving Corporation, until
thereafter changed or amended as provided therein or by Applicable Law;

provided, however, that the By-laws of the Surviving Corporation shall include

virtue of the Merger and without any action on the part of the holder of any
shares of Company Capital Stock or any shares of capital stock of Sub:

          (a)  Capital Stock of Sub.  Each issued and outstanding share of
               ---------------------
capital stock of Sub shall be converted into and become a number of fully paid
and nonassessable shares of common stock, par value $0.01 per share, of the

shares of Company Preferred Stock immediately prior to the Effective Time as
provided in paragraph (B) of Section 8 of the Company Preferred Certificate of
Designation (as defined in Section 2.01(c)) outstanding immediately prior to the
Effective Time divided by (ii) 1000; provided, however, that to the extent the
                                     --------  -------
aggregate number of shares of Surviving Corporation Common Stock into which the
capital stock of Sub is to be converted pursuant to this Section 2.01(a) is not
a whole number, such number shall be rounded up to the next higher whole number.

          (b)  Cancelation of Treasury Stock, Parent-Owned Stock and Sub-Owned
               ---------------------------------------------------------------
Stock.  Each share of Company Capital Stock that is owned by the Company, Parent
- ------
or Sub shall no longer be outstanding and shall automatically be canceled and
retired and shall cease to exist, and no Parent capital stock or other
consideration shall be delivered or deliverable in exchange therefor.  Each
share of Company Capital Stock that is owned by any Company Subsidiary (as
defined in Section 3.01) or Parent (other than Sub) shall automatically be
converted into one fully paid and nonassessable share of Surviving Corporation
Common Stock.

          (c)  Conversion of Company Capital Stock.  Subject to Section 2.01(b),
               ------------------------------------

                      --------------------------------------------
converted into the right to receive the Offer Price in cash.  The cash payable
upon the conversion of shares of Company Common Stock pursuant to this Section
2.01(c) is referred to, collectively as "Merger Consideration".  As of the
                                         --------------------

outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate representing any such shares of Company
Capital Stock shall cease to have any rights with respect thereto, except the
right to receive Merger Consideration upon surrender of such certificate in
accordance with Section 2.02, without interest.

          (d)  Appraisal Rights.  Notwithstanding anything in this Agreement to

Shares") of Company Common Stock that are outstanding immediately prior to the
- ------
Effective Time and that are held by any person who is entitled to demand and
properly demands appraisal of such Appraisal Shares pursuant to, and who
complies in all respects with, Section 262 of the DGCL ("Section 262") shall not
                                                         -----------
be converted into Merger Consideration as provided in Section 2.01(c), but,
rather, each holder of Appraisal Shares shall be entitled to payment of the fair
market value of such Appraisal Shares in accordance with Section 262; provided,
                                                                      --------
however, that, if any such holder shall fail to perfect or otherwise shall
- -------
waive, withdraw or lose the right to appraisal under Section 262, then the right
of such holder to be paid the fair value of such holder's Appraisal Shares shall
cease and such Appraisal Shares shall be deemed to have been converted as of the
Effective Time into, and to have become exchangeable solely for the right to
receive, Merger Consideration as provided in Section 2.01(c). The Company shall
provide prompt notice to Parent of any demands received by the Company for
appraisal of any shares of Company Capital Stock, and Parent shall have the
right to participate in and direct all negotiations and proceedings with respect
to such demands. Prior to the Effective Time, the Company shall not, without the
prior written consent of Parent, make any payment with respect to, or settle or
offer to settle, any such demands, or agree to do any of the foregoing.

          SECTION 2.02.  Exchange of Certificates. (a)  Paying Agent.  Prior to

the Effective Time, Parent shall select a bank or trust company to act as paying
agent (the "Paying Agent") for the payment of Merger Consideration upon
            ------------
surrender of certificates representing Company Common Stock.  Parent shall take
all steps necessary to enable and cause the Surviving Corporation to provide to
the Paying Agent, immediately following the Effective Time, all the cash
necessary to pay for the shares of Company Common Stock converted into the right
to receive cash pursuant to Section 2.01(c) (such cash, the "Exchange Fund").
                                                             -------------

          (b)  Exchange Procedure.  As soon as reasonably practicable after the
               -------------------
Effective Time, the Paying Agent shall mail to each holder of record of a
certificate or certificates (the "Certificates") that immediately prior to the
                                  ------------
Effective Time represented outstanding shares of Company Common Stock whose
shares were converted into the right to receive Merger Consideration pursuant to
Section 2.01, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Paying Agent and shall be in such
form and have such other provisions as Parent may reasonably specify), and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for Merger Consideration.  Upon surrender of a Certificate for cancelation to
the Paying Agent or to such other agent or agents as may be appointed by Parent,
together with such letter of transmittal, duly executed, and such other
documents as may reasonably be required by the Paying Agent, the holder of such
Certificate shall be entitled to receive in exchange therefor the amount of cash
into which the shares of Company Common Stock theretofore represented by such
Certificate shall have been converted pursuant to Section 2.01, and the
Certificate so surrendered shall forthwith be canceled.  In the event of a
transfer of ownership of Company Common Stock that is not registered in the
transfer records of the Company, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered if such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of such Certificate or establish to the satisfaction of Parent that such
tax has been paid or is not applicable.  Until surrendered as contemplated by
this Section 2.02, each Certificate shall be deemed, at any time after the
Effective Time, to represent only the right to receive upon such surrender the
amount of cash, without interest, into which the shares of Company Common Stock
theretofore represented by such Certificate have been converted pursuant to
Section 2.01.  No interest shall be paid or accrue on the cash payable upon
surrender of any Certificate.  If a mutilated Certificate is surrendered to the
Paying Agent or if the holder of a Certificate submits an affidavit to the
Paying Agent stating that the Certificate has been lost, destroyed or wrongfully
taken, such holder shall furnish an indemnity bond sufficient in the judgment of
Parent to

                                                                              11

protect Parent, the Surviving Corporation and the Paying Agent from any loss
that any of them may suffer.

          (c)  No Further Ownership Rights in Company Capital Stock.  The Merger
               -----------------------------------------------------
Consideration paid in accordance with the terms of this Article II upon
conversion of any shares of Company Common Stock shall be deemed to have been
paid in full satisfaction of all rights pertaining to shares of Company Capital
Stock, subject, however, to the Surviving Corporation's obligation to pay any
dividends or make any other distributions with a record date prior to the
Effective Time that may have been declared or made by the Company on such shares
of Company Capital Stock in accordance with the terms of this Agreement or prior
to the date of this Agreement and that remain unpaid at the Effective Time, and,
after the Effective Time, there shall be no further registration of transfers on
the stock transfer books of the Surviving Corporation of shares of Company
Capital Stock that were outstanding immediately prior to the Effective Time.
If, after the Effective Time, any Certificates are presented to the Surviving
Corporation or the Paying Agent for any reason, they shall be canceled and
exchanged as provided in this Article II.

          (d)  Termination of Exchange Fund.  Any portion of the Exchange Fund
               -----------------------------
that remains undistributed to the holders of Company Capital Stock for six
months after the Effective Time shall be delivered to Parent, upon demand, and
any holder of Company Capital Stock who has not theretofore complied with this
Article II shall thereafter look only to Parent for payment of its claim for
Merger Consideration.

          (e)  No Liability.  None of Parent, Sub, the Company or the Paying
               -------------
Agent shall be liable to any person in respect of any cash from the Exchange
Fund delivered to a public official pursuant to any applicable abandoned
property, escheat or similar Applicable Law.  If any Certificate has not been
surrendered prior to the date on which Merger Consideration in respect of such
Certificate would otherwise escheat to or become the property of any
Governmental Entity (as defined in Section 3.05(b)), any such shares, cash,
dividends or distributions in respect of such Certificate shall, to the extent
permitted by Applicable Law, become the property of the Surviving Corporation,
free and clear of all claims or interest of any person previously entitled
thereto.

          (f)  Investment of Exchange Fund.  The Paying Agent shall invest any
               ----------------------------
cash included in the Exchange Fund, as directed by Parent, on a daily basis.  If
for any reason (including losses) the Exchange Fund is inadequate to pay the
amounts to which holders of Company Capital Stock shall be entitled under this
Article II, Parent and the Surviving Corporation shall in any event be liable
for payment thereof.  The Exchange Fund shall not be used except as provided in
this Agreement.  Any interest and other income resulting from such investments
shall be paid to Parent.

          (g) Withholding Rights.  Parent or the Surviving Corporation shall be
              -------------------
entitled to deduct and withhold from the consideration otherwise payable to any
holder of Company Capital Stock pursuant to this Agreement such amounts as may

     required to comply with changes in Applicable Law occurring prior to the
     date of this Agreement.

          SECTION 3.09.  Taxes.  (a)  Each of the Company and each Company
                         ------
Subsidiary has timely filed, or has caused to be timely filed on its behalf, all
Tax Returns (as defined in Section 3.09(f)) required to be filed by it, and all
such Tax Returns are true, complete and accurate, except to the extent any
failure to file or any failure to be true, complete or accurate in any filed Tax
Returns would not, individually or in the aggregate, reasonably be expected to
have a Company Material Adverse Effect.  All Taxes shown to be due on such Tax
Returns, or otherwise owed, have been timely paid, except to the extent that any
failure to pay, individually or in the aggregate, has not had and would not
reasonably be expected to have a Company Material Adverse Effect.

          (b)  The most recent financial statements contained in the Filed
Company SEC Documents reflect an adequate reserve for all current Taxes payable
by the Company and the Company Subsidiaries (in addition to any reserve for
deferred Taxes established to reflect timing differences between book and Tax
income) for all taxable periods and portions thereof through the date of such
financial statements, except to the extent that any failures have not had and
would not reasonably be expected to have, individually or in the aggregate, a
Company Material Adverse Effect.  No deficiency with respect to any Taxes has
been proposed, asserted or assessed against the Company or any Company
Subsidiary, and no requests for waivers of the time to assess any such Taxes are
pending, except to the extent any such deficiency or request for waiver,
individually or in the aggregate, have not had and would not reasonably be
expected to have a Company Material Adverse Effect.

          (c) The Federal income Tax Returns of the Company and each corporation
that is a Company Subsidiary consolidated in such Tax Returns have been examined
by and settled with the United States Internal Revenue Service for all years
through 1991.  All material assessments for Taxes due with respect to such
completed and settled examinations or any concluded litigation have been fully
paid.

          (d)  As of the date of this Agreement, neither the Company nor any
Company Subsidiary is bound by any sharing, allocation or indemnification
agreement with respect to Taxes that is material to the business, financial
condition

or ongoing, longer-term profitability (but not prospects) of the Company and the
Company Subsidiaries, taken as a whole.

          (e)  Neither the Company nor any Company Subsidiary has constituted
either a "distributing corporation" or a "controlled corporation" (within the
meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock
qualifying for tax-free treatment under Section 355 of the Code (i) in the two
years prior to the date of this Agreement or (ii) in a distribution which
otherwise constitutes part of a "plan" or "series of related transactions"
(within the meaning of Section 355(e) of the Code) in conjunction with the
Merger.

          (f)  For purposes of this Agreement:

          "Taxes" includes all forms of taxation, whenever created or imposed,
           -----
and whether of the United States or elsewhere, and whether imposed by a local,

          SECTION 3.10.  Absence of Changes in Benefit Plans.  There has not
                         ------------------------------------

Company SEC Documents.  For purposes of this Agreement, the term "Company

Company
<PAGE>

                                                                              25

the terms and conditions of employment in connection with the hiring of such
individual and not providing for any entitlement to severance pay and benefits
in excess of $100,000.

          SECTION 3.11.  ERISA Compliance; Excess Parachute Payments.  (a)  The
                         --------------------------------------------
Company Disclosure Letter includes a copy of the Company's Associate Benefits

compensation and benefits provided pursuant to Company Benefit Plans for
employees of the Company and the Company Subsidiaries who are not U.S. Employees
are (i) with respect to expatriates, consistent with customary practice for
expatriate employees, and (ii) with respect to all other such employees,
designed to provide similar benefits to the U.S. Benefits, to the extent
possible subject to Applicable Law, and, in each case, the aggregate cost
thereof is not materially greater, on a per capita basis, than the aggregate
cost of the U.S. Benefits.  The Company has made available, or will hereafter
make available upon request, to Parent true, complete and correct copies of (i)
each Company Benefit Plan (or, in the case of any unwritten Company Benefit
Plan, a description thereof), (ii) the most recent annual report on Form 5500
filed with the Internal Revenue Service with respect to each Company Benefit
Plan (if any such report was required), (iii) the most recent summary plan
description for each Company Benefit Plan for which such summary plan

          (b)  All "employee pension benefit plans" (as defined in Section 3(2)
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
                                                                     -----

exempt from Federal income taxes under Sections 401(a) and 501(a), respectively,
of the Internal Revenue Code of 1986, as amended (the "Code"), and no such
                                                       ----
determination letter has been revoked nor, to the Knowledge of the Company, has
revocation been threatened, nor has any such Company Pension Plan been amended
since the date of its most recent determination letter or application therefor
in any respect that would adversely affect its qualification.  All Forms 5500
required to be filed with respect to Company Benefit Plans have been timely
filed.

          (c)  None of the Company, any Company Subsidiary, or any person that
is considered one employer with the Company under Section 4001 of ERISA or
Section 414 of the Code, has or could reasonably be expected to have any
liability under Title IV of ERISA with respect to any "employee benefit plan"
(as defined in Section 3(3) of ERISA) other than for payment of premiums to the
Pension Benefit Guaranty Corporation with respect to the defined benefit pension
plan disclosed in the Company Disclosure Letter.  None of the Company Pension
Plans has an "accumulated funding deficiency" (as such term is defined in
Section 302 of ERISA or Section 412 of the Code), whether or not waived.  None
of the Company, any Company Subsidiary, any officer of the Company or any of its
Company Subsidiary or any of the Company Benefit Plans that are subject to
ERISA, including the Company Pension Plans, and to the Knowledge of the Company,
any trusts created thereunder or any trustee or administrator thereof, have
engaged in a "prohibited transaction" (as defined in Section 406 of ERISA or
Section 4975 of the Code) or any other breach of fiduciary responsibility that
could subject the Company, any Company Subsidiary or any officer of the Company
or any Company Subsidiary to the Tax or penalty on prohibited transactions
imposed by such Section 4975 in any material amount or to any material liability
under Section 502(i) or 502(1) of ERISA.

          (d)  With respect to any Company Benefit Plan that is an employee
welfare benefit plan, except as disclosed in the Company Disclosure Letter, (i)
no such Company Benefit Plan is unfunded or funded through a "welfare benefits
fund" (as defined in Section 419(e) of the Code) and (ii) each such Company
Benefit Plan that is a "group health plan" (as defined in Section 5000(b)(1) of
the Code), complies with the applicable requirements of Section 4980B(f) of the
Code.  Neither the Company nor any Company Subsidiary has any obligations for
retiree health and life benefits under any

                                                                              27

Company Benefit Plan with respect to U.S. Employees (other than as required
under Section 4980B(f) of the Code).

          (e)  The Company Disclosure Letter sets forth a complete and accurate
list of each individual who is a party to a change-in-control employment
agreement with the Company, together with such individual's current base salary
and target bonus.

          SECTION 3.12.  Labor Matters.  There are no collective bargaining or
                         ---------------
other labor union agreements to which the Company or any Company Subsidiary is a
party or by which any of them is bound.  As of the date of this Agreement, to
the Knowledge of the Company, there is not any labor union organizing activity
or any actual or threatened employee strikes, work stoppages, slowdowns or
lockouts that, individually or in the aggregate, have had or would reasonably be
expected to have a Company Material Adverse Effect.

          SECTION 3.13.  Litigation.  There is no suit, action or proceeding
                         -----------
pending or, to the Knowledge of the Company, threatened against or affecting the
Company or any Company Subsidiary (and the Company is not aware of any basis for
any such suit, action or proceeding) that, individually or in the aggregate, has
had or would reasonably be expected to have a Company Material Adverse Effect,
nor is there any Judgment outstanding against the Company or any Company
Subsidiary that has had or would reasonably be expected to have a Company
Material Adverse Effect.  As of the date of this Agreement, there is no suit,
action or proceeding pending or, to the Knowledge of the Company, threatened
against or affecting the Company or any Company Subsidiary (and the Company is
not aware of any basis for any such suit, action or proceeding) that,
individually or in the aggregate, would reasonably be expected to have a
material adverse effect on the ability of the Company to consummate the
transactions contemplated by this Agreement, nor as of the date of this
Agreement is there any Judgment outstanding against the Company or any Company
Subsidiary that would reasonably be expected to have a material adverse effect
on the ability of the Company to consummate the transactions contemplated by
this Agreement.

          SECTION 3.14.  Compliance with Applicable Laws.  The Company and the
                         --------------------------------
Company Subsidiaries are in compliance with all Applicable Laws, including those
relating to occupational health and safety, except for such instances of
<PAGE>

                                                                              28

noncompliance that, individually or in the aggregate, have not had or would not
reasonably be expected to have a Company Material Adverse Effect.  As of the
date of this Agreement, the Company and the Company Subsidiaries are in
compliance with all Applicable Laws, including those relating to occupational
health and safety, except for such instances of noncompliance that, individually
or in the aggregate, would not reasonably be expected to have a material adverse
effect on the ability of the Company to consummate the transactions contemplated
by this Agreement.  To the Knowledge of the Company neither the Company nor any
Company Subsidiary has received any written communication during the past two
years from a Governmental Entity that alleges that the Company or a Company
Subsidiary is not in compliance with any Applicable Law, except with respect to
any alleged noncompliance that, individually or in the aggregate, would not
reasonably be expected to have a Company Material Adverse Effect.  This Section
3.13 does not relate to matters with respect to Taxes, which are the subject of
Section 3.09, or environmental matters, which are the subject of Section 3.18.

          SECTION 3.15.  Brokers; Schedule of Fees and Expenses.  No broker,
                         ---------------------------------------
investment banker, financial advisor or other person, other than Goldman, Sachs
& Co., the fees and expenses of which will be paid by the Company, is entitled
to any brokers', finders', financial advisors' or other similar fee or
commission in connection with the Offer, the Merger and the other transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
the Company.  The Company has furnished to Parent the financial details of all
agreements between the Company and Goldman, Sachs & Co. relating to the Offer,
the Merger and the other transactions contemplated by this Agreement.

          SECTION 3.16.  Opinion of Financial Advisor.  The Company has received
                         -----------------------------
the opinion of Goldman, Sachs & Co., dated the date of this Agreement, to the
effect that, as of such date, the consideration to be received in the Offer and
the Merger by the holders of Company Common Stock is fair to such holders from a
financial point of view, a signed copy of which opinion will promptly be
delivered to Parent upon receipt by the Company.

          SECTION 3.17.  Year 2000 Compliance.  (a)  To the Knowledge of the
                         ---------------------
Company, the computer systems of the Company and the Company Subsidiaries are
Year 2000 Compliant (as defined below), except to the extent that such failures
<PAGE>

                                                                              29

to be Year 2000 Compliant would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect.  All inventory
of the Company and the Company Subsidiaries that is, consists of, includes or
uses computer software is Year 2000 Compliant.  Any failure on the part of the
customers of and suppliers to the Company and the Company Subsidiaries to be
Year 2000 Compliant by December 31, 1999, is not expected to have a Company
Material Adverse Effect.  As of the date of this Agreement, the SAP project is
expected to be completed on schedule and within budget.

          (b)  The term "Year 2000 Compliant", with respect to a computer system
                         -------------------
or software program, means that such computer system or program: (i) is capable
of recognizing, processing, managing, representing, interpreting and
manipulating correctly date-related data for dates earlier and later than
January 1, 2000; (ii) has the ability to provide date recognition for any data
element without limitation for the purposes designed; (iii) has the ability to
function automatically into and beyond the year 2000 without human intervention
and without any change in operations associated with the advent of the year

dates, including February 29, 2000.

          SECTION 3.18.  Environmental Matters.  Neither the Company nor any
                         ----------------------
Company Subsidiary has (x) to the Knowledge of the Company, placed, held,
located, released, transported or disposed of any Hazardous Substances (as
defined below) on, under, from or at any of the Company's or any of the Company
Subsidiaries' properties, other than in a manner that would not, in all such
cases taken individually or in the aggregate, reasonably be expected to result
in a Company Material Adverse Effect, or (y) any Knowledge or reason to know of
the presence of any Hazardous Substances on, under or at any of the Company's or
any of the Company Subsidiaries' properties, other than in a manner that would
not, in all such cases taken individually or in the aggregate, reasonably be
expected to result in a Company Material Adverse Effect.  There are no claims,
investigations or administrative actions pending or, to the

Knowledge of the Company, threatened against or affecting the Company or any
Company Subsidiary arising from or related to the harmful effects of, or the
removal or remediation of, Hazardous Substances that has had or would be
reasonably expected to have a Company Material Adverse Effect. For purposes of
this Agreement, "Environmental Law" means any Applicable Law or Judgment of any
                 -----------------
Governmental Entity relating to any matter of pollution, protection of the
environment, environmental regulation or control or regarding Hazardous
Substances on or under any of the Company's or any of the Company Subsidiary's
properties or any other properties. For purposes of this Agreement, the term
"Hazardous Substance" shall mean any toxic or hazardous materials or substances,
 -------------------
including asbestos, buried contaminants, chemicals, flammable explosives,
radioactive materials, petroleum and petroleum products and any substances
defined as, or included in the definition of, "hazardous substances", "hazardous
wastes", "hazardous materials" or "toxic substances" under any Environmental
Law.

                         ----------------------------
Agreement, there are no contracts or agreements that are material to the conduct
of the business of the Company and the Company Subsidiaries taken as a whole
that are required to be filed as part of the Company SEC Documents.  Neither the
Company nor any of the Company Subsidiaries is in violation of or in default
under (nor does there exist any condition which upon the passage of time or the
giving of notice would cause such a violation of or default under) any Contract
to which it is a party or by which it or any of its properties or assets is
bound that, individually or in the aggregate, has had or would reasonably be
expected to have a Company Material Adverse Effect.

          SECTION 3.20.  Intellectual Property.  The Company and the Company
                         ----------------------
Subsidiaries own, or are validly licensed or otherwise have the right to use,
all patents, patent rights, trademarks, trademark rights, trade names, trade
name rights, service marks, service mark rights, copyrights and other
proprietary intellectual property rights and computer programs (collectively,
"Intellectual Property Rights") which are material to the conduct of the
 ----------------------------
business of the Company and the Company Subsidiaries taken as a whole, in each
case, as currently conducted.  No claims are pending or, to the Knowledge of the
Company, threatened that the Company or any of the Company Subsidiaries is
infringing or

otherwise adversely affecting the rights of any person with regard
to any Intellectual Property Right, except for such claims that would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.  To the Knowledge of the Company, no person is
infringing the rights of the Company or any of the Company Subsidiaries with
respect to any Intellectual Property Right, except for such infringements that,
individually or in the aggregate, have not had and would not reasonably be
expected to have a Company Material Adverse Effect.

                             ------------------------------
adverse effect on the ability of Parent to consummate the transactions
contemplated by this Agreement.  Each of Parent and Sub is duly qualified to do
business in each jurisdiction where the nature of its business or its ownership

failures to qualify that, individually or in the aggregate, have not had and
would not reasonably be expected to have a Parent Material Adverse Effect.

                         ------------
Sub has not carried on any business or conducted any operations other than the
execution of this Agreement, the performance of its obligations hereunder and

the Proxy Statement in preliminary form, and the Company shall use its
reasonable efforts to respond as promptly as practicable to any comments of the
SEC with respect thereto.  The Company shall notify Parent promptly of the
receipt of any comments from the SEC or its staff and of any request by the SEC
or its staff for amendments or supplements to the Proxy Statement or for
additional information, and shall supply Parent with copies of all
correspondence between the Company or any of its representatives, on the one
hand, and the SEC or its staff, on the other hand, with respect to the Proxy
Statement.  If at any time prior to receipt of the Company Stockholder Approval,
there shall occur any event that should be set forth in an amendment or
supplement to the Proxy Statement, the Company shall promptly prepare and mail
to its stockholders such an amendment or supplement.  The Company shall not mail
any Proxy Statement, or any amendment or supplement thereto, to which Parent
reasonably objects.  The Company shall use its reasonable efforts to cause the
Proxy Statement to be mailed to the Company's stockholders as promptly as
practicable after filing with the SEC.

          (b)  If the approval of this Agreement by the Company's stockholders
is required by Applicable Law, the Company shall, as soon as practicable
following the expiration of the Offer, duly call, give notice of, convene and
hold a meeting of its stockholders (the "Company Stockholders Meeting") for the
                                         ----------------------------
purpose of seeking the Company Stockholder Approval.  The Company shall, through
the Company Board, recommend to its stockholders that they give the Company
Stockholder Approval, except to the extent that the Company Board shall have
withdrawn or modified its approval or recommendation of this Agreement, the
Offer or the Merger as permitted by Section 5.02(b).  Without limiting the
generality of the foregoing, the Company agrees that its obligations pursuant to
the first sentence of this Section 6.01(b) shall not be affected by the
commencement, public proposal, public disclosure or communication to the Company
of any Company Takeover Proposal.  Notwithstanding the foregoing, if Parent, Sub
or any other subsidiary of Parent shall acquire at least 90% of the outstanding
shares of each outstanding class of capital stock of the Company entitled to
vote on the Merger, the parties shall, at the
<PAGE>

                                                                              44

request of Parent, take all necessary and appropriate action to cause the Merger
to become effective as soon as practicable after the expiration of the Offer
without a stockholders meeting in accordance with Section 253 of the DGCL.

          (c)  Parent shall cause all shares of Company Capital Stock purchased
pursuant to the Offer and all other shares of Company Capital Stock owned by
Parent, Sub or any other subsidiary of Parent to be voted in favor of the
approval of this Agreement.

          SECTION 6.02.  Access to Information; Confidentiality.  (a)  The
                         ---------------------------------------
Company shall, and shall cause each of the Company Subsidiaries to, afford to
Parent and to its officers, employees, accountants, counsel, financial advisors
and other representatives, reasonable access during normal business hours during
the period prior to the Effective Time to all of their properties, books,
contracts, commitments, personnel and records and, during such period, the
Company shall, and shall cause each of the Company Subsidiaries to, promptly
furnish to Parent (i) a copy of each report, schedule, registration statement
and other document filed by the Company or any of the Company Subsidiaries
during such period pursuant to the requirements of Federal or state securities
laws and (ii) all other information concerning its business, properties and
personnel as Parent may reasonably request, subject to legally binding
confidentiality restrictions with third parties in effect as of the date of this
Agreement.  Without limiting the generality of the foregoing, in the event the
Company receives a Company Takeover Proposal, the Company shall, within two
business days of request therefor, provide to Parent the information described
in Rule 14a-7(a)(2)(ii) under the Exchange Act and any information to which a
holder of Company Capital Stock would be entitled under Section 220 of the DGCL
(assuming such holder met the requirements of such section).  All information
exchanged pursuant to this Section 6.02 shall be subject to the Confidentiality
Agreement, dated November 16, 1999, between the Company and Parent (the
"Confidentiality Agreement").
 -------------------------

          (b)  The Company and Parent shall cooperate in determining whether the
Company or any Company Subsidiary is or has been a United States real property
holding corporation within the meaning of Section 897(c)(2) of the Code at any
time during the five year period ending at the Effective Time.

          SECTION 6.03.  Reasonable Efforts; Notification.  (a)  Upon the terms
                         ---------------------------------
and subject to the conditions set forth in this Agreement, each of the parties
shall use all reasonable efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, and to assist and cooperate with the other parties
in doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Offer, the Merger and
the other transactions contemplated by this Agreement, including (i) the
obtaining of all necessary actions or nonactions, and Consents from Governmental
Entities and the making of all necessary registrations and filings (including
filings with Governmental Entities, if any) and the taking of all reasonable
steps as may be necessary to obtain an approval or waiver from, or to avoid an
action or proceeding by, any Governmental Entity, (ii) the obtaining of all
necessary Consents from third parties, (iii) the defending of any lawsuits or
other legal proceedings, whether judicial or administrative, challenging this
Agreement or the consummation of the transactions contemplated by this
Agreement, including seeking to have any stay or temporary restraining order
entered by any court or other Governmental Entity vacated or reversed and (iv)
the execution and delivery of any additional instruments necessary to consummate
the transactions contemplated by this Agreement and to fully carry out the
purposes of this Agreement.  In connection with and without limiting the
foregoing, the Company and the Company Board shall, if any state takeover
statute or similar statute or regulation is or becomes applicable to any
transaction contemplated by this Agreement, take all action necessary to ensure
that the Offer, the Merger and the other transactions contemplated by this
Agreement may be consummated as promptly as practicable on the terms
contemplated by this Agreement.  Notwithstanding the foregoing, (x) the Company
shall not be prohibited under this Section 6.03(a) from taking any action
permitted by Section 5.02(b) and (y) nothing in this Agreement shall be deemed
to require any party to take any action that would result in any of the
consequences referred to in paragraph (a) of Exhibit A.

          (b)  The Company shall give prompt notice to Parent, and Parent or Sub
shall give prompt notice to the Company, of (i) any representation or warranty
made by it contained in this Agreement that is qualified as to a material
adverse effect becoming untrue or inaccurate in any respect or any such
representation or warranty that is not
<PAGE>

                                                                              46


so qualified becoming untrue or inaccurate in any material respect or (ii) the
failure by it to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall affect the
           --------  -------
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

          SECTION 6.04.  Company Employee Stock Options.  (a)  As soon as
                         -------------------------------
practicable following the date of this Agreement, the Company Board (or, if
appropriate, any committee administering the Company Stock Plans) shall adopt
such resolutions or take such other actions as are required, subject to any
required consent of the holders, to adjust the terms of all outstanding Company
Employee Stock Options and all outstanding Company SARs heretofore granted under
any Company Stock Plan to provide that each Company Employee Stock Option (and
any Company SAR related thereto) outstanding immediately prior to the acceptance
for payment of shares of Company Common Stock pursuant to the Offer shall be
canceled in exchange for a cash payment by the Company at that time of an amount
equal to (i) the excess, if any, of (x) the Merger Consideration over (y) the
exercise price per share of Company Common Stock subject to such Company
Employee Stock Option, multiplied by (ii) the number of shares of Company Common
Stock for which such Company Employee Stock Option shall not theretofore have
been exercised.  All amounts payable pursuant to this Section 6.04 shall be
subject to any required withholding of Taxes and shall be paid without interest.

          (b)  The Company shall use its reasonable best efforts to obtain all
consents of the holders of the Company Employee Stock Options as shall be
necessary to effectuate the foregoing and to ensure that following the Effective
Time no holder of a Company Employee Stock Option or Company SAR or any
participant in any Company Stock Plan or other Company Benefit Plan shall have
any right thereunder to acquire any capital stock of the Company or the
Surviving Corporation.  Notwithstanding anything to the contrary contained in
this Agreement, payment shall, at Parent's request, be withheld in respect of a
Company Employee Stock Option until all necessary consents in respect of such
Company Employee Stock Option are obtained.

          (c)  The Company Stock Plans shall terminate as of the Effective Time,
and the provisions in any other Benefit
<PAGE>

                                                                              47


Plan providing for the issuance, transfer or grant of any capital stock of the
Company or any interest in respect of any capital stock of the Company shall be
deleted as of the Effective Time.

          (d)  In this Agreement:

          "Company Employee Stock Option" means any option to purchase Company
           -----------------------------
     Common Stock granted under any Company Stock Plan.

          "Company SAR" means any stock appreciation right linked to the price
           -----------
     of Company Common Stock and granted under any Company Stock Plan.

          "Company Stock Plans" means the Company's Key Employees' 1992 Stock
           -------------------
     Option Plan, Key Employees' 1993 Stock Option Plan, Amended and Restated
     Restricted Stock Plan for Non-Employee Directors, Key Employees' 1982
     Incentive Stock Option Plan, as amended, 1985 Incentive Stock Option Plan,
     as amended, 1998 Stock Option Plan, as amended, Non-Employee Directors 1997
     Stock Plan and 1996 Stock Option Plan.

          SECTION 6.05.  Existing Agreements, Plans and Policies.  (a)  From and
                         ----------------------------------------
after the Effective Time, Parent shall, and shall cause the Surviving
Corporation to honor in accordance with their respective terms (as in effect on
the date of this Agreement), all the Company's employment, severance and
termination agreements, plans and policies disclosed in the Company Disclosure
Letter.

          (b)  If prior to the Effective Time Parent agrees to grant options to
acquire Parent Common Stock to any officer or director of the Company prior to
the Effective Time, the Board of Directors of Parent, or an appropriate
committee of non-employee directors thereof, shall if necessary adopt a
resolution consistent with the interpretive guidance of the SEC so that the
acquisition by any officer or director of the Company who may become a covered
person of Parent for purposes of Section 16 of the Exchange Act and the rules
and regulations thereunder ("Section 16") of options to acquire Parent Common
                             ----------
Stock pursuant to this Agreement and the Merger shall be an exempt transaction
for purposes of Section 16.

          (c)  For a period of not less than one year following the Effective
Time, Parent shall provide, or shall
<PAGE>

                                                                              48



cause to be provided, to current employees of the Company and the Company
Subsidiaries (the "Company Employees"), taken as a whole, employee benefits that
                   -----------------
are, in the aggregate, no less favorable than those provided from time to time
after the Effective Time to employees of Parent and its subsidiaries who are
similarly situated, in terms of positions and geographic locations, to such
Company Employees; provided, however, that nothing contained in this Section
                   --------  -------
6.05(c) shall require Parent to continue or cause to be continued any Company
Stock Plan. Without limiting the generality of the foregoing, all Company
Employees who are covered by the Company's Severance Pay Plan as in effect on
the date hereof and whose employment is terminated on or before the first
anniversary of the Effective Time shall be provided with severance pay and
benefits on a basis, and in amounts, not less favorable than those provided for
under the Company's Severance Pay Plan as in effect on the date hereof as
amended to reflect the amendment as described in the Company Disclosure Letter.

          (d)  For all purposes under the employee benefit plans of Parent and
its affiliates providing benefits to any Company Employees after the Effective
Time (the "New Plans"), each Company Employee shall be credited with his or her
           ---------
years of service with the Company and its affiliates before the Effective Time,
to the same extent as such Company Employee was entitled, before the Effective
Time, to credit for such service under any similar Company Benefit Plans, except
for purposes of benefit accrual under defined benefit pension plans.  In
addition, and without limiting the generality of the foregoing:  (i) each
Company Employee shall be immediately eligible to participate, without any
waiting time, in any and all New Plans to the extent coverage under such New
Plan replaces coverage under a comparable Company Benefit Plan in which such
Company Employee participated immediately before the Effective Time and
previously described to Parent (such plans, collectively, the "Old Plans"); and
                                                               ---------
(ii) for purposes of each New Plan providing medical, dental, pharmaceutical
and/or vision benefits to any Company Employee, Parent shall cause all pre-
existing condition exclusions and actively-at-work requirements of such New Plan
to be waived for such employee and his or her covered dependents (other than
limitations or waiting periods that are already in effect with respect to such
employees and dependents and that have not been satisfied as of the Effective
Time), and Parent shall cause any eligible expenses incurred by such employee
and his or her covered dependents during the
<PAGE>

                                                                              49


portion of the plan year of the Old Plan ending on the date such employee's
participation in the corresponding New Plan begins to be taken into account
under such New Plan for purposes of satisfying all deductible, coinsurance and
maximum out-of-pocket requirements applicable to such employee and his or her
covered dependents for the applicable plan year as if such amounts had been paid
in accordance with such New Plan.

          (e)  Parent agrees that for purposes of any of the Company Benefit
Plans conferring rights on a current or former employee, officer or director as
a result of a change of control of the Company, the consummation of the Merger
(or such earlier event contemplated hereby and specified in such Company Benefit
Plans) shall be deemed to constitute a "Change of Control" (as that term is
defined in such Company Benefit Plans).

          (f)  Subject to compliance by Parent with its obligations under
Sections 6.05(a) and 6.05(c), nothing contained in this Section 6.05 or
elsewhere in this Agreement shall be construed to prevent the termination of
employment of any individual Company Employee or any change in the employee
benefits available to any individual Company Employee or the amendment or
termination of any particular Company Benefit Plan to the extent permitted by
its terms as in effect immediately prior to the Effective Time.

          SECTION 6.06.  Indemnification.  (a) Parent shall, to the fullest
                         ----------------
extent permitted by Applicable Law, cause the Surviving Corporation to honor all
the Company's obligations to indemnify (including any obligations to advance
funds for expenses) the current or former directors or officers of the Company
and the Company Subsidiaries for acts or omissions by such directors and
officers occurring at or prior to the Effective Time to the extent that such
obligations of the Company exist on the date of this Agreement, whether pursuant
to the Company Charter, the Company By-laws, individual indemnity agreements or
otherwise, and such obligations shall survive the Merger and shall continue in
full force and effect in accordance with the terms of the Company Charter, the
Company By-laws and such individual indemnity agreements from the Effective Time
until the expiration of the applicable statute of limitations with respect to
any claims against such directors or officers arising out of such acts or
omissions.
<PAGE>

                                                                              50

          (b)  For a period of six years after the Effective Time, Parent shall
cause to be maintained in effect the current policies of directors' and
officers' liability insurance maintained by the Company (provided that Parent
may substitute therefor policies with reputable and financially sound carriers
of at least the same coverage and amounts containing terms and conditions which
are no less advantageous) with respect to claims arising from or related to
facts or events which occurred at or before the Effective Time; provided,
                                                                --------
however, that Parent shall not be obligated to make annual premium payments for
- -------
such insurance to the extent such premiums exceed 300% of the annual premiums
paid as of the date hereof by the Company for such insurance (such 300% amount,
the "Maximum Premium").  If such insurance coverage cannot be obtained at all,
     ---------------
or can only be obtained at an annual premium in excess of the Maximum Premium,
Parent shall maintain the most advantageous policies of directors' and officers'
insurance obtainable for an annual premium equal to the Maximum Premium;

provided, however, if such insurance coverage cannot be obtained at all, Parent
- --------  -------
shall purchase all available extended reporting periods with respect to pre-
existing insurance in an amount which, together with all other insurance
purchased pursuant to this Section 6.06(b), does not exceed the Maximum Premium.
The Company represents to Parent that the Maximum Premium is $955,500.  Parent
shall not, and shall cause the Company not to, take any action that would have
the effect of limiting the aggregate amount of insurance coverage required to be
maintained for the individuals referred to in this Section 6.06(b).

          (c)  From and after the consummation of the Offer, to the full extent
permitted by Applicable Law, Parent shall, and shall cause the Company (or any
successor to the Company) to, indemnify, defend and hold harmless the present
officers and directors of the Company and the Company Subsidiaries (each an

"Indemnified Party") against all losses, claims, damages, liabilities, fees and
 -----------------
expenses (including attorneys' fees and disbursements), judgments, fines and
amounts paid in settlement (collectively, "Losses") arising out of actions or
                                           ------
omissions occurring at or prior to the Effective Time in connection with this
Agreement, the Offer, the Merger and the other transactions contemplated hereby;

provided, however, that an Indemnified Party shall not be entitled to
- --------  -------
indemnification under this Section 6.06(c) for Losses arising out of actions or
omissions by the Indemnified Party constituting (i) a breach of this Agreement,
(ii) criminal conduct or (iii) any
<PAGE>

                                                                              51


violation of federal, state or foreign securities laws. In order to be entitled
to indemnification under this Section 6.06(c), an Indemnified Party must give
Parent and the Company written notice of any third party claim which may give
rise to any indemnity obligation under this Section 6.06(c), and Parent and the
Company shall have the right to assume the defense of any such claim through
counsel of their own choosing, subject to such counsel's reasonable judgment
that separate defenses that would create a conflict of interest on the part of
such counsel are not available. If Parent and the Company do not assume any such
defense, they shall be liable for all reasonable costs and expenses of defending
such claim incurred by the Indemnified Party, including reasonable fees and
disbursements of counsel and shall advance such reasonable costs and expenses to
the Indemnified Party; provided, however, that such advance shall be made only
                       --------  -------
after receiving an undertaking from the Indemnified Party that such advance
shall be repaid if it is determined that such Indemnified Party is not entitled
to indemnification therefor. Neither Parent nor the Company shall be liable
under this Section 6.06(c) for any Losses resulting from any settlement,
compromise or offer to settle or compromise any such claim or litigation or
other action, without the prior written consent of Parent or the Company.

          (d)  The Company shall not, and Parent shall not permit the Company
to, amend or repeal any provision of the certificate of incorporation or by-laws
of the Company after the consummation of the Offer if such action would
adversely affect the rights of individuals who on or prior to the consummation
of the Offer were entitled to advances, indemnification or exculpation
thereunder for actions or omissions by such individuals prior to the Effective
Time.  The individuals referred to in the preceding sentence shall include any
individuals who served as of the Effective Time as directors or officers of any
Company Subsidiary at the Company's request, it being acknowledged by the
parties hereto that each director or officer of the Company who is currently
serving as a director or officer of a Company Subsidiary is doing so at such
request of the Company.

          (e)  In the event the Surviving Corporation or any successor to the
Surviving Corporation (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity in such
consolidation or merger or (ii) transfers all or substantially all its
properties and assets to any person,
<PAGE>

                                                                              52


then, and in each case, proper provision shall be made so that the successors of
the Surviving Corporation honor the obligations of the Company set forth in this
Section 6.06.

          SECTION 6.07.  Fees and Expenses.  (a)  Except as provided below, all
                         ------------------
fees and expenses incurred in connection with the Offer, the Merger and the
other transactions contemplated by this Agreement shall be paid by the party
incurring such fees or expenses, whether or not the Merger is consummated.

          (b)  The Company shall pay to Parent:

                    (i) a fee of $12,500,000 if this Agreement is terminated
               pursuant to Section 8.01(f);

               Company Takeover Proposal is consummated that involves the person
               whose Superior Company Proposal resulted in such termination;

                    (iii) a fee of $12,500,000 if this Agreement is terminated
               pursuant to Section 8.01(d);

               fee of $12,500,000 if this Agreement is terminated in the
               circumstances contemplated by clause (iii) above and within 12
               months of such termination either (x) a Company Acquisition
               Proposal (as defined below) is consummated or (y) the Company
               enters into an agreement to consummate a Company Acquisition
               Proposal and any Company Acquisition Proposal is thereafter
               consummated that includes the person party to such agreement,
               whether or not such consummation is within such 12 month period;

                    (v) a fee of $12,500,000 if (A) after the date of this
               Agreement and prior to the termination of this Agreement, any
               person

               until the scheduled expiration date immediately following the
               date such Company Takeover Proposal is made (or such later date
               as the Offer may be extended at the Company's request pursuant to
               Section 1.01(a)), (C) the Minimum Tender Condition is not
               satisfied at the expiration of the Offer, (D) this Agreement is
               terminated pursuant to Section 8.01(b)(iii) and (E) within 12
               months of such termination the Company enters into an agreement
               to consummate a Company Acquisition Proposal;

                    (vi) in addition to the fee paid under clause (v) above, a
               fee of $12,500,000 if this Agreement is terminated in the
               circumstances contemplated by clause (v) above and thereafter a
               Company Acquisition Proposal is consummated that involves the
               person party to the agreement referred to in Section
               6.07(b)(v)(E); and

                    (vii) a fee of $25,000,000 if (A) after the date of this
               Agreement and prior to the termination of this Agreement, any
               person makes a Company Takeover Proposal, (B) the Offer remains

                         ----------
payment of, and payment by Sub for, any shares of Company Capital Stock pursuant

and paid for by Sub plus the number of shares of Company Capital Stock otherwise
owned by Sub or any other subsidiary of Parent bears to (ii) the number of Fully
Diluted Shares (as defined in Exhibit A), and the Company shall, at such time,
cause Sub's designees to be so elected; provided, however, that, in the event

event, if the number of Independent Directors shall be reduced below three for
any reason whatsoever, any remaining Independent Directors (or Independent
Director, if there shall be only one remaining) shall be entitled to designate

officers, stockholders or affiliates of the Company, Parent or Sub, and such
persons shall be deemed to be Independent Directors for purposes of this
Agreement.  Subject to Applicable Law, the Company shall take all action
requested by Parent necessary to effect any such election, including mailing to
its stockholders the Information Statement containing the information required

the Company shall make such mailing with the mailing of the Schedule 14D-9

 --------
information required to be included in the Information Statement with respect to
Sub's designees).  In connection with the foregoing, the Company  promptly
shall, at the option of Sub, use all reasonable efforts to either increase the
size of the Company Board or obtain the resignation of such number of its
current directors as is necessary to enable Sub's designees to be elected or
appointed to the Company Board as provided above.

the Partnership Agreement to waive, any rights it may have under Section 15.2 of
the Partnership Agreement to exercise (x) the "sell procedure" as set out in
Section 15.4 of the Partnership Agreement or (y) the "mandatory buy/sell
procedure" set out in Section 15.5 of the Partnership Agreement (the rights
referred to in clauses (x) and (y), together with the Buy Rights, are referred
to as the "Buy/Sell Rights"), in each case, as result of the consummation of the
           ---------------
transactions contemplated by the Amended and Restated Merger Agreement, made as
of June 20, 1999, between Parent, Weyerhaeuser Canada Limited and MacMillan
Bloedel Limited (the "MacMillan Bloedel Transaction").  The Company acknowledges

Buy/Sell Rights as a result of the MacMillan Bloedel Transaction and that the
inclusion of this Section 6.12 and Section 5.01(a)(xii) in this Agreement does
not constitute

an admission or the acceptance by Parent that any of such Buy/Sell Rights have
been triggered by the MacMillan Bloedel Transaction, and Parent acknowledges
that the Company believes that it is entitled to exercise the Buy/Sell Rights as
a result of the MacMillan Bloedel Transaction and that the inclusion of this
Section 6.12 and Section 5.01(a)(xii) in this Agreement does not constitute an
admission or the acceptance by the Company that any of such Buy/Sell Rights have
not been triggered by the MacMillan Bloedel Transaction. "Partnership Agreement"

Bloedel of America Inc. dated as of September 30, 1991, as amended by the
Amendment to Limited Partnership Agreement dated as of February 14, 1992.

          (b) If this Agreement is terminated pursuant to Section 8.01(f), the

MacMillan A Limited Partnership (the "Partnership") held under the Partnership

Agreement, and Parent shall, and shall cause its subsidiaries to, in each case,
subject to the next sentence, sell the Parent Interest to the Company, for
$700,000,000 in cash. Such purchase and sale shall be consummated simultaneously
with, and as a condition to, the consummation of the transactions contemplated
by any Company Takeover Proposal made by the person who made the Superior
Company Proposal that gave rise to such termination. In the agreement entered
into by the Company with such person in connection with such termination, such
person must unconditionally guarantee (for the benefit of Parent and its
subsidiaries) the obligations of the Company under this Section 6.12(b).

          (c)  If (i) after the date of this Agreement, any person makes a
Company Takeover Proposal or amends a Company Takeover Proposal made prior to
the date of this Agreement, (ii) the Offer remains open until the scheduled
expiration date immediately following the date such Company Takeover Proposal is
made (or such later date as the Offer may be extended to at the Company's
request pursuant to Section 1.01(a)), (iii) the Minimum Tender Condition is not
satisfied at the expiration of the Offer and (iv) this Agreement is terminated
pursuant to Section 8.01(b)(iii), then the Buy Rights, if any, resulting from
the MacMillan Bloedel Transaction shall terminate; provided, however,
                                                   --------  -------
notwithstanding anything in the Partnership Agreement to the contrary:

          (A) the Company may exercise the Buy Rights within the 10 day period
     beginning with the date of termination of this Agreement for a "Buy Price"
     of $700,000,000 in cash and otherwise pursuant to the terms of Section 15.3
     of the Partnership Agreement; and

          (B) if the Company does not exercise its right under clause (A) above
     and within 12 months following the date of such termination the Company
     enters into an agreement to consummate a Company Acquisition Proposal, or a
     Company Acquisition Proposal is consummated, the Company shall purchase the
     Parent Interest, and Parent shall, and shall cause its subsidiaries, to
     sell the Parent Interest to the Company, for $700,000,000 in cash, such
     purchase and sale to be consummated simultaneously with, and as a condition
     to, the consummation of such Company Acquisition Proposal.

          (d)  Notwithstanding anything contained in the Partnership Agreement
to the contrary, but subject to this Section 6.12, the Company may not exercise
the Buy Rights as a result of the MacMillan Bloedel Transaction if this
Agreement is terminated prior to the acceptance for payment of shares pursuant
to the Offer:

               (i)   in the circumstances contemplated by Section 6.12(b) or
          6.12(c);

               (ii)  pursuant to Section 8.01(d) or pursuant to Section
          8.01(b)(iii) following the failure of the condition in paragraph (f)
          of Exhibit A; or

               (iii) pursuant to Section 8.01(c) or pursuant to Section
          8.01(b)(iii) following the failure of the condition in paragraph (e)
          of Exhibit A because, in either case, (A) other than as disclosed in
          the Filed Company SEC Documents or the Company Disclosure Letter,
          since the date of the most recent audited financial statements
          included in the Filed Company SEC Documents and prior to the date of
          this Agreement, there shall have occurred any event, change, effect or
          development that, individually or in the aggregate, has had or is
          reasonably likely to have a Company Material Adverse Effect or (B)(1)
          any representation or warranty of the Company in this Agreement that

          and correct as of

          the date of this Agreement or (2) the representations and warranties
          of the Company that are not qualified as to Company Material Adverse
          Effect shall not be true and correct in all respects as of the date of
          this Agreement if the failure of all such representations and
          warranties in this clause (2) to be true and correct, individually or
          in the aggregate, is materially adverse to the transactions
          contemplated by this Agreement, taken as a whole.

          (e) Notwithstanding any provision to the contrary in the Partnership
Agreement, if this Agreement is terminated in accordance with the terms hereof
and none of Sections 6.12(b), 6.12(c) and 6.12(d) is applicable, the 90-day
period under the Partnership Agreement during which the Company may exercise its
Buy Rights, if any, in connection with the MacMillan Bloedel Transaction shall
be deemed to begin to run from the date of such termination of this Agreement.
Except with respect to the running of the 90-day period, the procedures
governing the Buy Rights as set forth in the Partnership Agreement, to the
extent applicable, shall apply.

          (f) Except as provided above, the Partnership Agreement shall continue
in full force and effect in accordance with its terms.

Sub an irrevocable option (the "Option") to purchase for a price of $42.00 per
                                ------
share (the "Per Share Price") in cash a number of shares of Company Common Stock
            ---------------
(the "Optioned Shares") equal to the Applicable Amount.  The "Applicable Amount"
      ---------------                                         -----------------
shall be the number of shares of Company Common Stock which, when added to the
number of shares of Company Common Stock owned by Parent and Sub immediately
prior to its exercise of the Option, would result in Sub owning immediately
after its exercise of the Option 90% of the then-outstanding shares of Company
Common Stock.  Sub may exercise the Option only if, at the time of exercise,
Parent, Sub and any other subsidiary of Parent shall have acquired at least
50.1% of the Fully Diluted Shares pursuant to the Offer.  The Option shall
expire if not exercised prior to the Effective Time.  The Per Share Price may,
at the election of Sub, be paid either (i) in cash or (ii) a combination of
$1.00 in cash and a promissory note of Parent in a principal amount equal to
$41.00, which promissory note shall mature in 12 months (and be prepayable at
any time by

payable at maturity.

          (b)  In the event that Sub wishes to exercise the Option, Sub shall
give written notice (the date of such notice, the "Notice Date") to the Company
                                                   -----------
specifying the number of Optioned Shares it will purchase pursuant to such
exercise and a place and date (not later than 10 business days from the Notice
Date) for the closing of such purchase.

          (c)  At any closing hereunder, (i) Sub will make payment to the
Company of the full purchase price for the Optioned Shares by (A) certified or
official bank check payable to the order to Company or by wire transfer to the
Company, in an amount equal to the product of the cash portion of the Per Share
Price (determined in accordance with the last sentence of Section 6.13(a))
multiplied by the number of Optioned Shares being purchased at such closing, and
(B) delivery of the promissory note described in the last sentence of Section
6.13(a), and (ii) the Company will deliver to Sub a duly executed certificate or
certificates representing the number of Optioned Shares so purchased, registered
in the name of Sub or its nominee in the denominations designated by Sub in its
notice of exercise.

          (d)  Parent and Sub represent that any Optioned Shares purchased by
Sub will be acquired for investment only and not with a view to any public
distribution thereof and Sub will not offer to sell or otherwise dispose of any
Optioned Shares so acquired by it in violation of the registration requirements
of the Securities Act.  The certificate(s) representing the shares of Company
Common Stock acquired pursuant to the exercise of the Option will bear a legend
indicating that such shares of Company Common Stock were sold without
registration under the Securities Act.

          (e)  In the event of any change in the number of outstanding shares of
Company Common Stock by reason of any stock dividend, stock split,
recapitalization, combination, exchange of shares, merger, consolidation,
reorganization or the like or any other change in the corporate or capital
structure of the Company that would have the effect of diluting Sub's rights
hereunder, the number of Optioned Shares and the Per Share Price shall be
adjusted appropriately so as to restore Sub to its rights hereunder with respect
to the Option; provided, however, that nothing in this Section 6.13(e) shall be
               --------  -------
construed as permitting the

with Applicable Law to cause the Trustee to comply with such direction, and the
parties hereto agree that any remaining cash proceeds shall be allocated to
participants and beneficiaries under the Company's Investment Plan in accordance
with Applicable Law.

The Weyerhaeuser Company
P.O. Box 2999
Tacoma, Washington 98477-2999

Ladies and Gentlemen:

        The Weyerhauser Company ("Weyerhauser") has requested information from
TJ International, Inc. (the "Company"), in connection with its consideration of
a possible transaction involving the acquisition of the Company by Weyerhauser
(a "Transaction"). As a condition to furnishing such information to you, the
Company requires that Weyerhauser agree, as set forth below, to treat
confidentially any information (whether prepared by the Company, its advisors or
otherwise, and whether oral or written) that the Company or its agents or
advisors, furnish to Weyerhauser or its representatives (which term, when used
herein with reference to Weyerhauser or the Company, shall include its
directors, officers, employees, affiliates, agents, advisors, representatives
and potential financing sources) (such information being collectively referred
to herein as the "Evaluation Material") and to take or abstain from taking
certain other actions set forth herein. The term "Evaluation Material" does not
include information that (i) is already in your possession, provided that such
information is not known by you to be subject to another confidentiality
agreement with or other obligation of secrecy to the Company or another party or
(ii) becomes generally available to the public other than as a result of a
disclosure by you or your representatives or (iii) becomes available to you on a
non-confidential basis from a source other than the Company or its advisors,
provided that such source is not known by you to be bound by a confidentiality
agreement with or other obligation of secrecy to the Company or another party.

        You hereby agree that the Evaluation Material will be used by you or
your representatives solely for the purpose of evaluating a possible
Transaction, and will be kept confidential by you and your representatives;
provided, however, that any such information may be disclosed to your
representatives who need to know such information for the purpose of evaluating
any such possible Transaction and who agree to keep such information
confidential and to be bound by this agreement to the same extent as if they
were parties hereto. You will be responsible for any breach of this agreement by
your representatives and the Company shall be entitled to directly enforce such
agreements.

<PAGE>

        You hereby acknowledge that you are aware, and that you will advise your
representatives who are informed as to the matters which are the subject of this
letter, that the United States securities laws prohibit any person who has
received from an issuer material, non-public information concerning the matters
which are the subject of this letter from purchasing or selling securities of
such issuer or from communicating such information to any other person under
circumstances in which it is reasonably foreseeable that such person is likely
to purchase or sell such securities.

        In the event that you or your representatives receive a request to
disclose all or any part of the information contained in the Evaluation Material
by deposition, interrogatory, request for documents, subpoena, civil
investigative demand or similar process or an order issued by a court of
competent jurisdiction or by a governmental body, you agree to (i) promptly
notify the Company of the existence, terms and circumstances surrounding such a
request, so that it may seek an appropriate protective order and/or waive your
compliance with the provisions of this letter agreement (and, if the Company
seeks such an order, to provide such cooperation as the Company shall reasonably
request) and (ii) if disclosure of such information is required in the opinion
of your counsel, who shall be reasonably satisfactory to the Company, exercise
your best efforts to obtain an order or other reliable assurance that
confidential treatment will be accorded to such of the disclosed information
which the Company so designates. In addition, to the extent you are otherwise
required to disclose under applicable law all or any part of the information
contained in the Evaluation Material (whether such requirement arises from
action taken by you or otherwise), you will only disclose such information as is
required to be disclosed under applicable law in the opinion of your counsel,
who shall be reasonably satisfactory to the Company.

        You also hereby agree that, for the period ending six months from the
date of this letter, you will not, without the Company's written consent,
directly or indirectly, solicit for employment (other than by means of a general
advertisement) any person who is currently employed in a management position
with the Company.

        Each of Weyerhauser and the Company agrees that, except as required by
applicable law or the applicable rules of any stock exchange, it will not, and
will cause its representatives not to, disclose to any person either the fact
that discussions or negotiations are taking place concerning a possible
Transaction or any of the terms, conditions or other facts with respect to any
such possible Transaction, including the status thereof.

        Although the Company has endeavored to include in the Evaluation
Material information which it believes to be relevant for the purpose of your
investigation, you understand that neither the Company nor any of its
representatives or advisors have made or make any representation or warranty as
to the accuracy or completeness of the Evaluation Material. You agree that
neither the Company nor its representatives or advisors shall have any liability
to you or any of your representatives resulting from the use or content of the
Evaluation Material or from any action taken or any inaction occurring in
reliance on the Evaluation Material, except as may be included in any definitive
agreement with respect to any Transaction.

        At the request of the Company or in the event that you do not proceed
with a Transaction you and your representatives shall promptly redeliver to the
Company all written

                                      -2-
<PAGE>

Evaluation Material and any other written material containing or reflecting any
information in the Evaluation Material (whether prepared by the Company, its
advisors, agents or otherwise)and will not retain any copies, extracts or other
reproductions in whole or in part of such written material. All documents,
memoranda, notes and other writings whatsoever prepared by you or your
representatives based on the information in the Evaluation Material shall be
destroyed, and such destruction shall be certified in writing to the Company by
an authorized officer supervising such destruction.

     It is further understood and agreed that no failure or delay by either
party hereto in exercising any right, power or privilege it may have under this
letter shall operate as a waiver thereof, nor shall any single or partial
exercise thereof preclude any other or further exercise thereof or the exercise
of any right, power or privilege hereunder.

     You and we agree that unless and until a definitive agreement between the
Company and you with respect to a Transaction has been executed and delivered,
neither the Company nor you will be under any legal obligation of any kind
whatsoever with respect to such a Transaction by virtue of this or any written
or oral expression with respect to such a Transaction by any of its directors,
officers, employees, agents or any other representatives or its advisors except
for the matters specifically agreed to in this letter. You and we further
acknowledge and agree that (i) neither party hereto shall have any obligation to
authorize or pursue with the other party any Transaction, and (ii) each party
reserves the right, in its sole and absolute discretion, to reject all proposals
and to terminate discussions and negotiations with the other party at any time.
You further acknowledge and agree that the Company has not, as of the date
hereof, authorized any Transaction and that the Company reserves the right to
discontinue the provision of Evaluation Material to you at any time.

     The agreements set forth in this letter agreement may be modified or waived
only by a separate writing between the Company and you expressly so modifying or
waiving such agreements.

     The parties hereto acknowledge that money damages are an inadequate remedy
for breach of this letter agreement because of the difficulty of ascertaining
the amount of damage that will be suffered by you or the Company in the event
that this agreement is breached. Therefore, each party hereto agrees that the
other party may obtain specific performance of this agreement and injunctive or
other equitable relief as a remedy for any such breach and further waives any
requirement for the securing or posting of any bond in connection with any
such remedy. Such remedy shall not be deemed to be the exclusive remedy for any
breach of this letter agreement, but shall be in addition to all other remedies
available at law or equity. If any term, provision, covenant or restriction of
this letter agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

     This letter agreement shall be goverened by, and construed in accordance
with, the internal laws of the State of Delaware, without giving effect to the
principles of conflicts of laws thereof. Each party hereto consents to the
jurisdiction and venue for any action to enforce the provisions of this letter
agreement in any state or federal court in the State of Delaware.

                       [LETTERHEAD OF TJ INTERNATIONAL]


                                        November 30, 1999

To our Stockholders:

   We are pleased to report that on November 23, 1999, TJ International, Inc.
entered into an Agreement and Plan of Merger with Weyerhaeuser Company and one
of its subsidiaries, WTJ, Inc., that provides for the acquisition of all of the
outstanding shares of capital stock of TJ at a price of $42.00 per share in
cash. Under the terms of the proposed acquisition, Weyerhaeuser and WTJ, Inc.
have today commenced a tender offer for all of the outstanding shares of TJ
Common Stock and TJ ESOP Convertible Preferred Stock at a price of $42.00 per
share. Following the completion of the tender offer, WTJ, Inc. will be merged
with and into TJ, and all shares not purchased in the tender offer (other than
those owned by Weyerhaeuser, WTJ, Inc. or TJ, or by holders who have perfected
appraisal rights) will be converted into the right to receive $42.00 per share
in cash in the merger.

   Your Board of Directors has unanimously (i) approved the Merger Agreement,
Weyerhaeuser's tender offer and the proposed merger, (ii) determined that the
transactions contemplated by the Merger Agreement, including Weyerhaeuser's
tender offer and the merger, are fair to and in the best interests of TJ and
its stockholders and (iii) recommended that the stockholders of TJ accept
Weyerhaeuser's tender offer and tender their shares to WTJ pursuant to the
tender offer.

   In arriving at its recommendation, the Board of Directors gave careful
consideration to a number of factors. Among other things, these factors include
the opinion of Goldman, Sachs & Co., financial advisor to TJ, that, as of
November 23, 1999, the $42.00 per share in cash proposed to be paid in
Weyerhaeuser's tender offer and the merger to the holders of TJ Common Stock
was fair from a financial point of view to such holders.

   Accompanying this letter is a copy of TJ's Solicitation/Recommendation
Statement on Schedule 14D-9, which describes in more detail the reasons for
your Board's conclusions and includes in Annex B the entire text of the opinion
of Goldman, Sachs & Co. provided to the TJ Board of Directors regarding
Weyerhaeuser's tender offer and the proposed merger, including assumptions
made, matters considered and limitations in connection with such opinion. Also
enclosed is Weyerhaeuser's Offer to Purchase and related materials, including a
Letter of Transmittal for use in tendering shares. Weyerhaeuser's documents set
forth the terms and conditions of the tender offer and provide instructions as
to how to tender your shares. We urge you to read the enclosed materials
carefully and to consider carefully all information presented.

   The Board of Directors, Management and Associates of TJ thank you for the
support you have given TJ over these many years.

                       On behalf of the Board of Directors,

WEYERHAEUSER TO ACQUIRE TJ INTERNATIONAL FOR $720 MILLION

FEDERAL WAY, Wash. - Weyerhaeuser Company (NYSE: WY), one of North America's
largest forest products companies, today announced an agreement with TJ
International (NASDAQ: TJCO) that will make Weyerhaeuser the leading provider of
"value added" engineered wood products.

Under the definitive agreement, Weyerhaeuser will pay $720 million in cash, or
$42 per share, to acquire all outstanding shares of TJ International, a 51
percent owner and managing partner of Trus Joist MacMillan (TJM). Weyerhaeuser
currently owns 49 percent of Trus Joist MacMillan, the world's leading
manufacturer and marketer of engineered lumber products.

"Trus Joist MacMillan provides an excellent opportunity to grow our value-added
wood business and is a logical extension of our acquisition of MacMillan
Bloedel," said Steven R. Rogel, Weyerhaeuser chairman, president and chief
executive officer. "Engineered wood is a high-margin product with solid growth
potential and Trus Joist MacMillan is the leading company in this area. It is
the worldwide leader in sales, innovation and product quality in its segment. It
has the premier brand name that is associated with quality. This acquisition
will provide us with a growing stream of cash flow and earnings."

Harold E. Thomas, chairman of TJ International and co-founder of Trus Joist
MacMillan, said that today's announcement also will result in significant
customer benefits.

"I have always believed in the critical importance of innovation in our products
and services," Thomas said. "I have long admired the Weyerhaeuser Company and
believe that the organization that will emerge in the months ahead will take
engineered wood products to the next level."

The acquisition further enhances the long-standing relationship between
Weyerhaeuser and TJM. Weyerhaeuser is one of TJM's largest suppliers of raw
material and serves as its largest distributor.

Weyerhaeuser expects the acquisition to generate approximately $50 million in
annual savings, primarily through improving purchasing practices, distribution
and streamlining operations. The acquisition will be immediately accretive to
Weyerhaeuser's earnings and cash flow.

"This is an opportune time to complete this acquisition," Rogel said. "The
outlook for housing starts, interest rates and global GDP remains relatively
strong, and Trus Joist MacMillan's business is closely aligned with ours. This
acquisition will enable us to achieve a smooth and rapid integration of
production, sales, marketing and service. Equally important, it allows us to
capture meaningful synergies that are only possible from the combination of
Weyerhaeuser, MacMillan Bloedel and TJ International."

Weyerhaeuser intends to finance this transaction using cash and existing credit
arrangements. It will account for the acquisition as a purchase. The transaction
is subject to normal regulatory approvals. Weyerhaeuser will commence a tender
offer for all outstanding shares of TJ International within the next five
business days and the companies anticipate a closing date early next year.

"This combination offers significant value to Trus Joist MacMillan customers and
employees and TJ International shareholders," said Tom Denig, Trus Joist
MacMillan president and chief executive officer. "We've worked with Weyerhaeuser
for a long time and we share similar philosophies in innovation and enhanced
product offerings, backed by quality customer support. Additionally, we will
combine production, marketing and distribution efforts, enabling both companies
to realize valuable synergies."

Weyerhaeuser is the world's largest producer of softwood lumber and market pulp
and the world's largest owner of softwood timber. The company also is the third
largest producer of containerboard in the United States and the world's second
largest manufacturer of oriented strand board (OSB). Weyerhaeuser is one of the
largest producers of corrugated packaging in the U.S.

Boise, Idaho-based Trus Joist MacMillan manufactures a variety of engineered
lumber products for structural framing and industrial applications. It currently
operates 16 manufacturing facilities across North America and employs nearly
4,000 people around the world. Trus Joist MacMillan's unique patented
manufacturing technologies transforms wood fiber into high-performance,
consistent products. The company, which utilizes small-diameter trees that
provide resource-efficient alternatives to traditional sawmill products, further
enhances Weyerhaeuser's wood product line.

Weyerhaeuser Company one of the world's largest integrated forest products
companies, was incorporated in 1900. It has offices or operations in 12
countries, with customers worldwide. Weyerhaeuser is principally engaged in the
growing and harvesting of timber; the manufacture, distribution and sale of
forest products; and real estate construction, development and related
activities.

Board of Directors
TJ International, Inc.

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $1.00
per share (the "Shares"), of TJ International, Inc. (the "Company") of the
$42.00 per Share in cash proposed to be paid by Sub (as defined below) in the
Tender Offer and the Merger (as such terms are defined below) pursuant to the
Agreement and Plan of Merger, dated as of November 23, 1999, among Weyerhaeuser
Company ("Parent"), WTJ, Inc., a wholly-owned subsidiary of Parent ("Sub"), and
the Company (the "Agreement"). The Agreement provides for a tender offer for
all of the Shares (the "Tender Offer") pursuant to which Sub will pay $42.00
per Share in cash for each Share accepted. The Agreement further provides that
following completion of the Tender Offer, Sub will be merged into the Company
(the "Merger") and each outstanding Share, other than Appraisal Shares, as
defined in the Agreement, and other than Shares owned by the Company, Parent or
Sub will be converted into the right to receive $42.00 in cash.

Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, including
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes. We are familiar with the Company having provided certain investment
banking services to the Company from time to time, including having acted as
its financial advisor in connection with, and having participated in certain of
the negotiations leading to, the Agreement. We also have provided certain
investment banking services to Parent and MacMillan Bloedel Ltd., which Parent
recently acquired, from time to time, including having acted as co-managing
underwriter of a public offering by Parent in October 1997 of $300 million of
6.95% debentures due in 2027 and may provide investment banking services to
Parent in the future. Goldman, Sachs & Co. provides a full range of financial
advisory and

securities services and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of the Company or Parent for its own account and for the accounts
of customers.

In connection with this opinion, we have reviewed, among other things, the
Agreement; the Partnership Agreement (as defined in the Agreement); Annual
Reports to Stockholders and Annual Reports on Form 10-K of the Company for the
five fiscal years ended January 2, 1999; certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company; certain other
communications from the Company to its stockholders; and certain internal
financial analyses and forecasts for the Company prepared by its management. We
also have held discussions with members of the senior management of the Company
regarding its past and current business operations, financial condition and
future prospects. In addition, we have reviewed the reported price and trading
activity for the Shares, compared certain financial and stock market
information for the Company with similar information for certain other
companies the securities of which are publicly traded, reviewed the financial
terms of certain recent business combinations in the Forest Products and
Building Materials industries specifically and in other industries generally
and performed such other studies and analyses as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us and have assumed such accuracy and
completeness for purposes of rendering this opinion. In addition, we have not
made an independent evaluation or appraisal of the assets and liabilities of
the Company or any of its subsidiaries and we have not been furnished with any
such evaluation or appraisal. We were not requested to solicit, and did not
solicit, interest from other parties with respect to an acquisition of or other
business combinations with the Company. Our advisory services and the opinion
expressed herein are provided for the information and assistance of the Board
of Directors of the Company in connection with its consideration of the
transaction contemplated by the Agreement and such opinion does not constitute
a recommendation as to whether or not any holder of Shares should tender such
Shares in connection with such transaction.

Based upon and subject to the foregoing and based upon such other matters as we
consider relevant, it is our opinion that as of the date hereof the $42.00 per
Share in cash proposed to be paid by Sub in the Tender Offer and the Merger to
the holders of the Shares is fair from a financial point of view to such
holders.

Very truly yours,
