We are asking you to furnish copies of the enclosed materials to your clients for whom you hold Weyerhaeuser common shares, whether such shares are registered in your name or in the name of your nominee. You will be reimbursed for customary mailing and handling expenses incurred by you in forwarding any of the enclosed materials to your clients.

As described in the Prospectus—Offer to Exchange, Weyerhaeuser is not conducting the exchange offer in any jurisdiction where the offer, sale or exchange is not permitted. If you are in a jurisdiction where offers to exchange or sell, or solicitations of offers to exchange or purchase, the securities offered by the exchange offer are unlawful, or if you are a person to whom it is unlawful to direct these types of activities, then the exchange offer presented does not extend to you.

No broker, dealer, bank, trust company or fiduciary shall be deemed to be the agent of Weyerhaeuser, Weyerhaeuser Real Estate Company (“WRECO”), TRI Pointe Homes, Inc. (“TRI Pointe”), the exchange agent, the transfer agent or the information agent for purposes of the exchange offer.

TRI Pointe’s obligation to consummate the Merger and convert WRECO common shares into shares of TRI Pointe common stock is subject to certain conditions, as described in the Prospectus—Offer to Exchange in the section entitled “This Exchange Offer—Conditions for Consummation of this Exchange Offer,” which you should review in detail.

For your information and for forwarding to your clients for whom you hold Weyerhaeuser common shares, registered in your name or in the name of your nominee, we are enclosing the following documents:

1. the Prospectus—Offer to Exchange, dated [    ], 2014;

2. a Letter of Transmittal (the “Letter of Transmittal”) for validly tendering Weyerhaeuser common shares, including instructions therefore and including a Certification of Taxpayer Identification Number on IRS Substitute Form W-9;

3. a Notice of Guaranteed Delivery, to be used to accept the exchange offer if the Weyerhaeuser common shares and other required documents cannot be delivered to the exchange agent by the expiration of the exchange offer;

4. the Guidelines for Certification of Taxpayer Identification Number on IRS Substitute Form W-9 U.S. Taxpayers included in the Letter of Transmittal;

5. IRS Form W-8BEN for non-U.S. Taxpayers;

6. a printed form of a Client Letter, which may be sent to your clients for whose accounts you hold Weyerhaeuser common shares registered in your name or in the name of your nominee, with space for obtaining such clients’ instructions with regard to the exchange offer;

7. a form of Notice of Withdrawal for use in withdrawing Weyerhaeuser common shares previously tendered in the exchange offer; and

8. a return envelope addressed to the exchange agent, for your use only.

YOUR PROMPT ACTION IS REQUESTED. WE URGE YOU TO CONTACT YOUR CLIENTS AS PROMPTLY AS POSSIBLE. PLEASE NOTE THAT THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON [    ], 2014, UNLESS THE EXCHANGE OFFER IS EXTENDED OR TERMINATED.

Weyerhaeuser common shares tendered pursuant to the exchange offer may be withdrawn at any time prior to the expiration of the exchange offer and, unless Weyerhaeuser has previously accepted them pursuant to the exchange offer, may also be withdrawn at any time after the expiration of 40 business days from the commencement of the exchange offer.
