in an effort to maximize long-term value for shareholders. Each of the Reporting
Persons may make further purchases of shares of Common Stock from time to time

the proposed sale of Masonite to KKR (the "Transaction"). The Reporting Persons

of shareholders the Reporting Persons intend to continue discussions with the
management of Masonite regarding how they may maximize the long-term value for
shareholders. Each of the Reporting Persons may, at any time and from time to
time, review or reconsider his or its position and formulate plans or proposals
with respect thereto.

                                  Press Release


New York, NY            January 27, 2005

Eminence Capital, LLC, New York, NY is issuing the following press release. This
press release represents the entire content of a letter that was presented by
Eminence Capital, LLC to the Board of Directors of Masonite International
Corporation on January 26, 2005:

As you may know, Eminence Capital LLC ("Eminence Capital") is a significant
shareholder of Masonite International Corporation (the "Company"), owning
approximately 3.8% of its outstanding common shares.

We are writing to you because we strongly oppose the announced leveraged buyout
of Masonite by Stile Acquisition Corp., an affiliate of Kohlberg Kravis Roberts
& Co. ("KKR"). We think the company is worth far more than the C$40.20 per share
purchase price. Also, based on our review of the proxy, we believe that the
Special Committee of the Board of Directors, in reaching its conclusion that the
offer is substantively fair to the shareholders of Masonite, relied upon factors
and assumptions that were materially inconsistent with management's recent
comments to shareholders about those same factors and assumptions.

We believe Masonite ("MHM") is worth at least C$50 per share. This can be
supported by the same valuation techniques used in the analysis your investment
banker prepared for the Special Committee of the Board of Directors. Our
analysis, however, points out several inconsistencies and flaws we see in the
analysis performed by the banker.

These inconsistencies and flaws are as follows:

      1)  Management of the Company supplied your banker with financial
          projections that were very inconsistent with statements your CEO Phil
          Orsino and Executive VP Larry Repar made to shareholders of the
          Company as recently as October 20, 2004. Management's projections used
          by your banker appear to assume an internal revenue growth rate of 1%
          - 3% compared to the 7% - 10% growth rate management discussed on its
          July and October earnings calls. [SEE ORGANIC GROWTH DISCUSSION BELOW]
          We performed LBO and DCF analyses using the assumptions presented in
          the proxy, however, assuming an internal growth rate of 7% (the
          low-end of management's range) and we calculate the mid-points of fair
          value at C$48 per share in the LBO analysis and C$53 per share in the
          DCF analysis. These values are C$7 - C$10 per share higher than the
          values (mid-points) your banker derived in its analysis.

      2)  Your banker applied a 20% to 35% discount to the comparable company
          multiple when valuing MHM because MHM has historically traded at a
          discount to its US peers. We believe that based on MHM's leading
          market position, solid internal growth rate and strong cash flow, the
          company is worth at least a comparable multiple to its US peers. Using
          the same EPS figure as your banker used in its analysis,

          US$2.71 per share, we calculate a fair comparable company value of
          C$48.00 per share. This assumes no control premium though one is
          clearly justified.

      3)  Your banker used an LTM EBITDA figure that was not adjusted for the
          full-year effect of acquisitions that MHM consummated in the last nine
          months. When we value MHM's LTM EBITDA, adjusted for acquisitions, at
          the same multiple as the peer group presented in the proxy (no
          discount applied) we arrive at a value of C$46.00 per share, again
          assuming no control premium. This value is C$13.50 per share higher
          than the mid-point price in your banker's analysis.


We find it disconcerting that your banker (the Special Committee's financial
advisor) was supplied financial projections by management that were
significantly below the very targets management spoke about on its conference
calls with investors as recently as October 20, 2004. These projections were
also well below the projections management originally supplied to KKR, also in
October 2004. Specifically, the projections supplied to the investment bankers
for purposes of determining "Fairness" incorporate internal revenue growth
assumptions far below levels that management publicly spoke about on its two
most recent earnings conference calls.

Below we have provided the inconsistencies between the organic revenue growth
rate assumptions provided by the Company to its banker and what was said to the
public on the July 19th, 2004 and October 20th, 2004 conference calls.

ORGANIC GROWTH DISCUSSION:

The projections supplied to your banker for the purpose of their fairness
opinion assumed a compounded annual growth rate ("CAGR") in total revenues from
2005 to 2009 of 6.3%. This growth rate included revenue added through US$100
million per year of acquisition spending. Backing out these acquisitions, this
forecast implies internal revenue growth of 1% to 3%, far below management's
recent projections of 7% to 10%.

On the July 19, 2004 conference call with investors1, your CEO Phil Orsino
stated:
      "Well, you know, what we targeted and what we talked about was that over
      the next three to five years that we could achieve growth of 7 to 10% top
      line. And we are still very, very confident in those target ranges."

On the October 20, 2004 conference call, management continued to support this
target growth rate:

      QUESTION FROM SELL SIDE ANALYST: "What's the outlook for organic growth in
      your assessment right now for sales growth in 2005? Can we do
      double-digit-plus?"

      ANSWER FROM LARRY REPAR: "We are maintaining the targets that we have
      discussed throughout the year - organic growth ranging between 7 and 10
      percent, and we are going to maintain that target for 2005."

      ANSWER FROM PHILIP ORSINO: "I mean, if economic conditions continue to be
      similar to what they are at this point in time, then obviously in the same
      way that we broke through that range, so far this year we could continue
      to break through that range going into next year as well."

Given the above, we believe that the financial projections and valuation
multiples used to evaluate the fairness of KKR's offer were significantly
understated. We do not agree that the current offer reflects a fair price for
the Company and believe the Company is worth at least C$50 per share based on a
number of valuation parameters. Moreover, we are troubled by the sudden change
in management's outlook for the business and would note that as participants in
the transaction, management has a conflict of interest.

We intend to vote against the transaction as currently configured. Should we and
other shareholders vote this transaction down, we strongly urge the Board of
Directors of the Company to take one of the following actions:

  1)  Execute management's recently stated plan without any further disruptions
      and accelerate the Company's recently announced share repurchase program,
      possibly through a Dutch Auction; and / or

  2)  Implement a leverage recapitalization of the Company and pay a significant
      special dividend to current shareholders.


We have always been a supportive shareholder of the Company and believe that the
Company is a well-managed business with favorable growth prospects. We are
disappointed by the value that is being offered by KKR and the management team
and find it disappointing in this day and age that you have recommended that KKR
and management insiders acquire the Company, and its upside potential, for an
inadequate price. We also believe that other significant shareholders share our
concerns about the transaction.
