2. We have made such investigations of law as we have deemed appropriate as a basis for this opinion.

For purposes of this opinion, we have not reviewed any documents other than the documents listed in 1(a)-(k) above. In particular, we have not reviewed any document (other than the documents listed in paragraphs 1(a)-(k) above) that is referred to in or incorporated by reference into the documents reviewed by us. We have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with the opinions stated herein. We have conducted no independent factual investigation of our own but rather have relied as to the factual matters solely upon the foregoing documents, the statements and information set forth

therein and the additional matters recited or assumed herein, all of which we have assumed to be true, complete and accurate in all material respects.

In rendering the opinions expressed below, we have assumed, with your permission, without independent investigation or inquiry, (a) the authenticity of all executed documents submitted to us, (b) the genuineness of all signatures, (c) the conformity to authentic originals of documents submitted to us as certified, conformed or photostatic copies, and (d) the due authorization, execution and delivery of each of the foregoing documents by each party thereto (other than the Corporation).

For the purposes of this opinion, we have assumed (i) that the Bylaws constitute the entire agreement among the parties thereto with respect to the subject matter thereof, including the creation, operation, dissolution and termination of, the Corporation, and that the Bylaws are in full force and effect and have not been amended and no amendment of the Bylaws is pending or has been proposed, (ii) except to the extent provided in paragraph 1 below, that each of the parties to the documents examined by us has been duly created, organized or formed, as the case may be, and is validly existing in good standing under the laws of the jurisdiction governing its creation, organization or formation, (iii) the legal capacity of natural persons who are parties to the documents examined by us, (iv) except to the extent provided in paragraph 2 below, that each of the parties to the documents examined by us has the power and authority to execute and deliver, and to perform its obligations under, such documents, and (v) except to the extent provided in paragraph 3 below, that each of the parties to the documents examined by us has duly authorized, executed and delivered such documents. We have not participated in the preparation of the Registration Statement or Current Report and assume no responsibility for their contents.

Based upon and subject to the foregoing and the qualifications hereinafter set forth, we are of the opinion that:

1. The Corporation is validly existing and in good standing under the Michigan Business Corporation Act, MCL §450.1101 et seq. (the “Act”).

2. Under the Act, the Bylaws, the Initial Consent and the Consent, the Corporation has all necessary corporate power and authority to execute and deliver the Third Supplemental Indenture and to perform its obligations thereunder and under the Indenture and Third Supplemental Indenture.

3. Under the Act, the Bylaws, the Initial Consent, and the Consent the execution and delivery by the Corporation of the Third Supplemental Indenture, and the performance by the Corporation of its obligations under the Third Supplemental Indenture and the Indenture (including the issuance by the Corporation of the Subsidiary Guarantee under Article Fourteen of the Indenture) have been duly authorized by all necessary corporate action on the part of the Corporation.

4. The Third Supplemental Indenture has been duly executed and delivered by the Corporation, to the extent that execution and delivery thereof are governed by the laws of the State of Michigan.

5. Under the Act, the Bylaws, the Initial Consent and the Consent, the Corporation has all necessary corporate power and authority to file, or cause to be filed, the Current Report with the Securities and Exchange Commission.

Our opinions set forth above are subject to the limitations and effects of (a) bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights or remedies generally and (b) general equitable principles (whether considered in a proceeding in equity or at law). Our opinions set forth above are also subject to the effects of (i) an implied covenant of good faith, reasonableness and fair dealing, (ii) limitations on enforceability of rights to the extent any indemnification would violate public policy, and (iii) limitations, to the extent applicable to the Corporation, of any applicable usury laws or other similar laws affecting the charging and collection of interest on loans in the State of Michigan.

We express no opinion as to the validity or perfection of any security interest, or the validity, binding effect or enforceability of the Indenture, First Supplemental Indenture or Third Supplemental Indenture to the extent that the Indenture, First Supplemental Indenture or Third Supplemental Indenture grants or purports to grant a security interest.

We express no opinion as to the ability or viability of the Corporation to undertake, fulfill or satisfy any of its financial obligations under the Indenture, First Supplemental Indenture or Third Supplemental Indenture and have not reviewed or investigated the financial statements and/or the financial status of the Corporation, all of which are subject to the limitations set forth herein.

We express no opinion as to the effect of, or compliance with, any laws of the State of Michigan regarding fraudulent transfers or conveyances, or provisions of Michigan law restricting dividends, loans or other distributions by a corporation or for the benefit of its stockholders.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of Michigan (excluding the securities laws of the State of Michigan) that, in our experience, are generally applicable to transactions of this type. In particular, and without limiting the generality of the foregoing, we express no opinion as to the laws of any jurisdiction or as to the effect of such laws, whether limiting, prohibitive or otherwise, on any of the rights or obligations of any other party to or beneficiary of the Indenture.

The opinions expressed herein are given solely as of the date hereof. We assume no obligation to supplement this opinion if any applicable laws change after the date of this opinion, or if we become aware of any facts that might change the opinions expressed above after the date of this opinion.

We hereby consent to the filing of this opinion as an exhibit to Domtar Corporation’s Current Report on Form 8-K filed on or about June 9, 2009, incorporated by reference in the Registration Statement, and to the reference to our firm under the caption “Legal matters” in the Prospectus. In giving such consent, we do not thereby concede that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and

regulations of the Commission thereunder. Except as stated above, without our prior written consent, this opinion may not be furnished or quoted to, or relied upon by, any other Person for any purpose.

Very truly yours,

HOOPER, HATHAWAY, PRICE, BEUCHE & WALLACE
