RICHMOND, British Columbia & FORT MILL, S.C. (News release) -- Karta Halten B.V., a private limited company organized under the laws of the Netherlands ("Karta Halten"), through its wholly owned subsidiary, Pearl Merger Sub Inc., a Delaware corporation ("Merger Sub") and affiliate of Paper Excellence B.V., a private limited company organized under the laws of the Netherlands ("Paper Excellence"), announced today (i) the extension of the previously announced tender offers (each, an "Offer" and together, the "Offers") by Merger Sub to purchase for cash any and all of Domtar Corporation's ("Domtar") outstanding (a) 6.25% Senior Notes due 2042 (the "2042 Notes") and (b) 6.75% Senior Notes due 2044 (the "2044 Notes" and, together with the 2042 Notes, the "Notes," each such series of the Notes, a "Series") and of the related consent solicitations (the "Offer Consent Solicitations"), (ii) an increase to the Total Tender Offer Consideration (as defined below) offered to holders of each Series of the Notes that validly tender (and do not validly withdraw) their Notes in the Offers prior to the Early Tender Deadline (as defined below) and (iii) other amendments to the terms of the Offers and the Offer Consent Solicitations described in more detail below and as set forth in Supplement No. 2, dated August 23, 2021, to the Offer to Purchase and Consent Solicitation Statement, dated August 9, 2021 (as supplemented, and as it may be further supplemented and amended from time to time, the "Offer to Purchase"). In addition, Domtar announced today the extension of Domtar's previously announced consent solicitations (the "Domtar Consent Solicitations"), which solicit consents from the holders of the Notes of each Series to certain proposed amendments to the senior indenture governing the Notes (the "Indenture"), as well as an increase to the consent payment (the "Change of Control Consent Solicitation Payment") offered to holders of each Series of the Notes that validly deliver (and do not validly revoke) consents in the Domtar Consent Solicitations prior to the Consent Solicitation Deadline (as defined below).

The Offers

Merger Sub has announced today that it has increased the amount of the total tender offer consideration (the "Total Tender Offer Consideration") with respect to each of the Offers from $1,012.50 per $1,000 principal amount of Notes of each Series to $1,020.00 per $1,000 principal amount of Notes of each Series accepted by Merger Sub for purchase and validly tendered (and not validly withdrawn) by holders of the Notes prior to the Early Tender Deadline. This is the result of an increase in the amount of the early tender payment (the "Early Tender Payment") with respect to each of the Offers from $50.00 per $1,000 principal amount of Notes of each Series to $57.50 per $1,000 principal amount of Notes of each Series accepted by Merger Sub for purchase and validly tendered (and not validly withdrawn) by holders of the Notes prior to the Early Tender Deadline. The Tender Offer Consideration with respect to each of the Offers remains unchanged at $962.50 per $1,000 principal amount of Notes of each Series accepted by Merger Sub for purchase and validly tendered (and not validly withdrawn) by holders of the Notes following the Early Tender Deadline but prior to the Expiration Time (as defined below).

Merger Sub also announced that it has extended the time and date by which (1) holders of Notes must validly tender (and not validly withdraw) their Notes in the Offers and the Offer Consent Solicitations to be eligible to receive the Early Tender Payment (such time and date, as extended and as the same may be further extended, the "Early Tender Deadline") to 5:00 p.m., New York City time, on August 27, 2021, (2) Notes validly tendered pursuant to the Offers and the Offer Consent Solicitations may be withdrawn (such time and date, as extended and as the same may be further extended, the "Withdrawal Deadline") to 5:00 p.m., New York City time, on August 27, 2021, and (3) holders of Notes must validly tender (and not validly withdraw) their Notes in the Offers and the Offer Consent Solicitations to be eligible to receive the Tender Offer Consideration (such time and date, as extended and as the same may be further extended, the "Expiration Time") to Midnight (end of day), New York City time, on October 1, 2021.

In addition, Merger Sub has announced that it is making the following modifications to the terms of the Offers and the Offer Consent Solicitations. First, Merger Sub is modifying the terms of the Offer Consent Solicitations to exclude the Offer Exit Proposed Amendments (other than the Reporting Covenant Amendment and the amendment to the definition of "Change of Control" under the Indenture to exclude the Paper Excellence Transaction) from the proposed amendments to the Indenture that are being solicited from holders of the Notes of each Series in connection with the Offer Consent Solicitations. This means that only (i) Offer Exit Consents to the Reporting Covenant Amendment to the Indenture and (ii) Offer Change of Control Consents to the Change of Control Proposed Amendments to the Indenture are being solicited from holders of each Series of Notes in connection with the Offer Consent Solicitations. As a result, the proposed amendments to the Indenture do not include an amendment to eliminate substantially all of the restrictive covenants in the Indenture or an amendment to eliminate certain of the events which may lead to an "Event of Default" in the Indenture. Second, Merger Sub has announced that it now expects to accept Notes of each Series validly tendered (and not validly withdrawn) in the Offers if, prior to the Expiration Time, (a) the Change of Control Requisite Consent Condition has been satisfied with respect to any Series of Notes by the submission of Solicitation Change of Control Consents in respect of a majority of the aggregate principal amount outstanding of such Series of Notes, without counting Offer Change of Control Consents, and (b) the Change of Control Supplemental Indenture has been executed with respect to such Series of Notes. This means that if Solicitation Change of Control Consents have been submitted in respect of a majority of the aggregate principal amount of the outstanding Notes of a Series pursuant to the Domtar Consent Solicitations and, as a result, a Change of Control Supplemental Indenture has been executed with respect to such Series of Notes, then Merger Sub intends to accept for purchase any Notes of such Series validly tendered (and not validly withdrawn) in the Offers.

As of 5:00 p.m., New York City time, on August 20, 2021, approximately $57.5 million in aggregate principal amount of 2042 Notes and approximately $43.6 million in aggregate principal amount of 2044 Notes have been validly tendered (and not validly withdrawn) in the Offers.

The Domtar Consent Solicitations

Domtar has announced that it has increased the consent payment (the "Change of Control Consent Solicitation Payment") in connection with the Domtar Consent Solicitations from $2.50 per $1,000 principal amount of Notes to $10.00 per $1,000 principal amount of Notes of each Series validly delivered for consent (and not validly revoked) by holders of Notes of each Series prior to the Consent Solicitation Deadline.

Domtar also announced that it has extended the time and the date by which holders of the Notes must validly deliver (and not validly revoke) consents in connection with the Domtar Consent Solicitations to be eligible to receive the Change of Control Consent Solicitation Payment to 5:00 p.m., New York City time on August 27, 2021 (such time and date, as extended and as the same may be further extended, the "Consent Solicitation Deadline").

As of 5:00 p.m., New York City time on August 20, 2021, holders of approximately $15.2 million in aggregate principal amount of 2042 Notes and holders of approximately $5.8 million in aggregate principal amount of 2044 Notes have validly delivered (and not validly revoked) consents in the Domtar Consent Solicitations.

With the exception of the foregoing amendments, all other terms and conditions of the Offers, the Offer Consent Solicitations and the Domtar Consent Solicitations, as previously announced and described in the Offer to Purchase, remain unchanged.
