RECENT DEVELOPMENTS

On April 18, 2012, we announced that the Supreme Court of Canada had refused to hear an appeal by Fibrek and Mercer International Inc. (“Mercer”) of the Québec Court of Appeal’s decision rendered on March 27, 2012 confirming the cease trade order granted by the Bureau de décision et de révision (Québec) (the “BDR”) on Fibrek’s private placement of 32,320,000 special warrants to Mercer. Accordingly, the order issued by the BDR on February 23, 2012 is now final and non-appealable, and Fibrek’s private placement of 32,320,000 special warrants to Mercer has been definitively cease traded.

On April 19, 2012, we announced that Mercer had withdrawn its application before the BDR requesting an order to cease trade the Offer. Mercer had initially filed its application with the BDR on March 29, 2012.

Take-up and Payment of Fibrek Shares

On April 12, 2012, we announced that a total of 60,831,859 Fibrek Shares were validly deposited and that the conditions of our Offer were satisfied by 11:59 p.m. (Eastern Time) on April 11, 2012 and that we had thus taken up all of the Fibrek Shares validly deposited and not withdrawn as of that time.

On April 23, 2012, we took up an additional 2,664,351 Fibrek Shares that had been validly deposited between April 12, 2012 and the close of business on April 23, 2012 (including shares deposited with a Notice of Guaranteed Delivery). All of the Fibrek Shares taken up on April 23, 2012 were deposited into the Cash Only Option. After proration, approximately Cdn$1.5 million is being paid and 76,000 shares of Resolute Common Stock are being issued as Offer Consideration for the Fibrek Shares taken up by us on April 23, 2012.

Accordingly, after giving effect to the take-up of the deposited Fibrek Shares, we hold approximately 48.8% of the issued and outstanding Fibrek Shares (or approximately 47.7% calculated on a fully-diluted basis).

If following the extension of the Offer pursuant to this Notice of Variation and Extension, we are successful in acquiring at least 90% of the issued and outstanding Fibrek Shares (calculated on a fully-diluted basis) under the Offer, we intend to acquire the Fibrek Shares not deposited under the Offer on the same terms as the Fibrek Shares acquired under the Offer pursuant to a Compulsory Acquisition or pursuant to a Subsequent Acquisition Transaction, as described in the Offer to Purchase and Circular, as amended and supplemented by the Prior Notices.

If we do not acquire at least 90% of the issued and outstanding Fibrek Shares (calculated on a fully-diluted basis) under the Offer, we currently intend, depending upon the number of Fibrek Shares taken up and paid for under the Offer, to take such action as is necessary or advisable, including causing one or more special meetings of Fibrek shareholders to be called to consider a Subsequent Acquisition Transaction, as described in the Offer to Purchase and Circular, as amended and supplemented by the Prior Notices.

Following the consummation of either a Compulsory Acquisition, or a Subsequent Acquisition Transaction, we intend to cause Fibrek to apply to delist the Fibrek Shares from the TSX and to file an application with the relevant Canadian securities regulatory authorities for Fibrek to cease to be a reporting issuer.

MARKET PRICES AND EXCHANGE RATE

On April 23, 2012, the closing sale prices of Resolute Common Stock on the NYSE and TSX were US$13.05 and Cdn$12.89, respectively, and the closing sale price of the Fibrek Shares on TSX was Cdn$0.95. In addition, on April 23, 2012, the exchange rate for one U.S. dollar expressed in Canadian dollars based on the Bank of Canada Noon Rate was Cdn$0.9936. Fibrek shareholders are encouraged to obtain current market quotations for Resolute Common Stock and Fibrek Shares and current exchange rate information prior to making any decision with respect to the Offer.

On April 23, 2012, by written notice given to the Depositary and as set forth in this Notice of Variation and Extension, we amended and supplemented our Offer to Purchase and Circular dated December 15, 2011, as amended and supplemented by the Prior Notices, pursuant to which we are offering to purchase, on the terms and subject to the conditions contained therein, all of the issued and outstanding Fibrek Shares (the “Original Offer”). Unless the context otherwise requires, capitalized terms used but not defined herein have the meanings set forth in the Offer to Purchase and Circular, as amended and supplemented by the Prior Notices.

Except as otherwise set forth in this Notice of Variation and Extension, the terms and conditions of the Original Offer set forth in the Offer to Purchase and Circular, as amended and supplemented by the Prior Notices, continue to be applicable in all respects. This Notice of Variation and Extension should be carefully read in conjunction with the Offer to Purchase and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery, in each case as amended and supplemented by the Prior Notices.

All references to the “Offer” in the Offer to Purchase and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery, in each case as amended and supplemented by the Prior Notices, and in this Notice of Variation and Extension mean the Original Offer, as further amended and supplemented by this Notice of Variation and Extension.

We are extending the expiry time of the Offer to 5:00 p.m. (Eastern time) on May 4, 2012.

In connection with the foregoing, the definition of “Expiry Time” included in the Offer to Purchase and Circular, as amended and supplemented by the Prior Notices, is deleted and the following definition is added to the “Glossary” section in the appropriate alphabetical order:

“Expiry Time” means 5:00 p.m., Eastern Time, on May 4, 2012 or as may be extended.

We will not amend the Offer in such a manner as would cause the Expiry Time to occur earlier than 5:00 p.m., Eastern Time, on May 4, 2012.

The Expiry Time may be subject to extensions, depending on the timing of receipt of regulatory approvals and other factors.

In addition, all references to “5:00 p.m., Eastern Time, on April 23, 2012” in the Offer to Purchase and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery that accompanied the Offer to Purchase and Circular, each as amended and supplemented by the Prior Notices, are amended so as to now refer to “5:00 p.m., Eastern Time, on May 4, 2012”.
