PART II: INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20:  Indemnification of Directors and Officers.

The following is a summary of the statutes, charter and bylaw provisions or other arrangements under which the registrants’ directors and officers are insured or indemnified against liability in their capacities as such. All of the directors and officers of the registrants are covered by insurance policies maintained and held in effect by Terra Industries Inc. against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act.

Registrants Incorporated Under Delaware Law

Beaumont Ammonia Inc., Beaumont Holdings Corporation, BMC Holdings Inc., Port Neal Corporation, Terra (U.K.) Holdings Inc., Terra Capital, Inc., Terra Capital Holdings, Inc., Terra International (Oklahoma) Inc., Terra International, Inc., Terra Methanol Corporation, Terra Nitrogen Corporation, Terra Houston Ammonia, Inc., Terra Mississippi Nitrogen Inc. and Terra Nitrogen GP Holdings, Inc. are incorporated under the laws of the State of Delaware. Section 145 of the General Corporation Law of the State of Delaware (the “Delaware Statute”) provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), other than an action by or in the right of such corporation, by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise (an “indemnified capacity”). The indemnity may include expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. Similar provisions apply to actions brought by or in the right of the corporation, except that no indemnification shall be made without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred. Section 145 of the Delaware Statute further authorizes a corporation to purchase and maintain insurance on behalf of any indemnified person against any liability asserted against him and incurred by him in any indemnified capacity, or arising out of his status as such, regardless of whether the corporation would otherwise have the power to indemnify him under the Delaware Statute. The articles of incorporation and/or by-laws of these corporations provide that the respective corporation shall indemnify and hold harmless, to the fullest extent permitted by law, each person who is or was made a party, threatened to be made a party, or otherwise involved in any action, suit, or proceeding by reason of the fact that he or she is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, partner, or agent of another corporation, partnership, joint venture, or other enterprise, against expenses, liabilities, and losses. Furthermore, the directors of these respective corporations shall not be liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the Delaware Statute.

Registrants Incorporated Under Iowa Law

Terra Real Estate Corporation is incorporated under the laws of the State of Iowa. Section 490.851 of the Iowa Business Corporation Act (“IBCA”) provides that a corporation has the power to indemnify its directors and officers against liabilities and expenses incurred by reason of such person serving in the capacity of director or officer, if such person has acted in good faith and in a manner reasonably believed by the individual to be in or not opposed to the best interests of the corporation, and in any criminal proceeding if such person had no reasonable cause to believe the individual’s conduct was unlawful. The foregoing indemnity provisions notwithstanding, in the case of actions brought by or in the right of the corporation, no indemnification shall be made to such director or officer with respect to any matter as to which such individual has been adjudged to be liable to the corporation unless, and only to the extent that, a court determines that indemnification is proper under the circumstances.

The By-laws of Terra Real Estate Corporation provide that any person who is or was an officer, director, employee or agent of the corporation, or is or was serving at the request of this corporation as an officer, director, employee or agent of another corporation, partnership, joint venture, trust or enterprise, shall be entitled to indemnification to the same extent as permitted or required by the IBCA.

II-1

Registrants Incorporated Under Mississippi Law

Terra Mississippi Holdings Corp. is a corporation organized under the laws of the State of Mississippi. Indemnification of such registrant’s directors and officers provided by applicable law, by the registrant’s organizational documents, by contract or otherwise are substantially similar to that afforded by the directors and officers of Terra Industries Inc.

Registrants Incorporated Under Maryland Law

Terra Industries Inc. is incorporated under the laws of the State of Maryland. The Maryland General Corporation Law (“MGCL”) permits a corporation to indemnify its directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made a party by reason of their service in those or other capacities, unless it is established that (a) the act or omission of the directors or officer was material to the matter giving rise to such proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services, or (c) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the action or omission was unlawful.

The MGCL permits the charter of a Maryland corporation to include a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages, except to the extent that (i) the person actually received an improper benefit or profit in money, property or services or (ii) a judgment or other final adjudication is entered in a proceeding based on a finding that the person’s action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. Article SEVENTH, Paragraph (8) of Terra Industries Inc.’s Charter provides for indemnification of directors and officers of Terra Industries Inc. as follows. The Corporation shall indemnify (a) its directors to the full extent provided by the general laws of the State of Maryland now or hereafter in force, including the advance of expenses under the procedures provided by such laws; (b) its officers to the same extent it shall indemnify its directors; and (c) its officers who are not directors to such further extent as shall be authorized by the Board of Directors and be consistent with law. The foregoing shall not limit the authority of the Corporation to indemnify other employees and agents consistent with law. Terra Industries Inc.’s Charter also contains a provision providing for elimination of the liability of its directors or officers to the registrant or its stockholders for money damages to the fullest extent permitted by Maryland law.

Item 21.   Exhibits.

(a)   Exhibits.

The attached Exhibit Index is incorporated by reference.

(b)   Financial Statement Schedules.

The following financial statement schedules are included in this Registration Statement:

The financial statement schedule filed as part of this Registration Statement is listed in the Index to Financial Statements on page F-1. Schedule II (Valuation of Qualify Accounts for the Years Ended December 31, 2006, 2005 and 2004 is shown following the consolidated financial statements on page F-46.

Item 22.   Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

II-2

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 20, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a directors, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue

(c) For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as a part of this Registration Statement in reliance on Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be a part of this registration statement as of the time it was declared effective.

(d) For purposes of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) The undersigned hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the date of the registration statement through the date of responding to the request.

(f) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Terra Capital, Inc.

600 Fourth Street, P.O. Box 6000
Sioux City, Iowa 51102-6000

Re: Registration Statement on Form S-4

Ladies and Gentlemen:

     We are issuing this opinion letter in our capacity as special legal counsel to Terra Capital, Inc., a Delaware corporation (the “Issuer”), Terra Industries, Inc., a Maryland corporation (the “Parent Guarantor”) and each of the other guarantors listed on Schedule A hereto (collectively with the Parent Guarantor, the “Guarantors” and, collectively with the Issuer, the “Registrants”). This opinion letter is being delivered in connection with the proposed registration by the Issuer of $330,000,000 in aggregate principal amount of the Issuer’s 7% Senior Notes due 2017, Series B (the “Exchange Notes”) and the registration by the Guarantors of the guarantees of the Exchange Notes (the “Exchange Guarantees”) pursuant to a Registration Statement on Form S-4, originally filed with the Securities and Exchange Commission (the “Commission”) on March 30, 2007 under the Securities Act of 1933, as amended (the “Act”) (such Registration Statement, as amended or supplemented, is hereinafter referred to as the “Registration Statement”).

     The Exchange Notes and the Exchange Guarantees are to be issued pursuant to an Indenture, dated as of February 2, 2007 (as may be amended or supplemented from time to time, the “Indenture”), among the Issuer, the Guarantors and U.S. Bank National Association, as trustee. The Exchange Notes and the Exchange Guarantees are to be issued in exchange for and in replacement of the Issuer’s outstanding 7% Senior Notes due 2017 (the “Existing Notes”) and the guarantees thereof, of which $330,000,000 in aggregate principal amount with respect to the 7% Senior Notes due 2017 are subject to the exchange offer pursuant to the Registration Statement.

     In connection with issuing this opinion letter, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate records and other instruments as we have deemed necessary for the purposes of this opinion, including (i) resolutions of the Registrants with respect to the issuance of the Exchange Notes and the Exchange Guarantees, (ii) the Indenture, (iii) the Registration Statement, (iv) the Registration

Rights Agreement, dated as of February 2, 2006, by and among Issuer, the Parent Guarantor and Citigroup Global Markets Inc.

     For purposes of this opinion, we have assumed the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of all documents submitted to us as copies. We have also assumed the legal capacity of all natural persons, the genuineness of the signatures of persons signing all documents in connection with which this opinion is rendered, the authority of such persons signing on behalf of the parties thereto (other than the Registrants) and the due authorization, execution and delivery of all documents by the parties thereto (other than the Registrants). We have not independently established or verified any facts relevant to the opinions expressed herein, but have relied upon statements and representations of officers and other representatives of the Registrants and others.

     Our opinion expressed below is subject to the qualifications that we express no opinion as to the applicability of, compliance with, or effect of (i) any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent conveyance, moratorium or other similar law affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law) and (iii) public policy considerations which may limit the rights of the parties to obtain certain remedies.

     Based upon and subject to the assumptions, qualifications, exclusions and limitations and the further limitations set forth below, we are of the opinion that when (i) the Registration Statement becomes effective, (ii) the Indentures have been duly qualified under the Trust Indenture Act of 1939, as amended, and (iii) the Exchange Notes have been duly executed and authenticated in accordance with the provisions of the Indentures and duly delivered to the holders thereof in exchange for the Existing Notes, the Exchange Notes will be binding obligations of the Issuer and the Exchange Guarantees will be binding obligations of the Guarantors.

     We hereby consent to the filing of this opinion with the Commission as Exhibit 5.1 to the Registration Statement. We also consent to the reference to our firm under the heading “Validity of New Securities” in the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission.

     Our advice on every legal issue addressed in this letter is based exclusively on the internal law of the State of New York or the General Corporation Law of the State of Delaware (including the statutory provisions, all applicable provisions of the Delaware constitution and reported judicial decisions interpreting the foregoing), and represents our opinion as to how that issue would be resolved were it to be considered by the highest court in the jurisdiction which enacted such law. The manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it. For purposes of our opinion that the Exchange Guarantees will be binding obligations of Terra Industries Inc., Terra Real Estate Corporation and Terra Mississippi Holdings Corp., we have, without conducting any research or investigation with respect thereto, relied on the opinion of local counsel that, (i) Terra Industries Inc. has (A) the requisite corporate power to execute, deliver, and perform its obligations under the Exchange Guarantee, (B)  that the execution and delivery of the Exchange Guarantee has been duly authorized by all necessary corporate action under its articles of incorporation and bylaws, (C) when such Exchange Guarantee is executed and delivered by an authorized officer, such Exchange Guarantee will be duly authorized, executed and delivered and (D) the execution and delivery of the Exchange Guarantee will not contravene the Maryland General Corporation Law; (ii) Terra Real Estate Corporation has (A) the corporate power to execute and deliver, and perform its obligations under, the Exchange Guarantee, (B) the execution, delivery and performance of the Exchange Guarantee have been duly authorized by all necessary corporate action by such Guarantor, (C) the execution and delivery of the Exchange Guarantee and the performance by such Guarantor of its obligations thereunder do not and will not conflict with or constitute or result in a breach or default under such Guarantor’s articles of incorporation or bylaws or any applicable statute of the State of Iowa or require any consent of any State of Iowa court or governmental authority; and (iii) Terra Mississippi Holdings Corp. has (A) the corporate power to enter into and perform its obligations under the Exchange Guarantee, (B) the execution and delivery of the Indenture by such Guarantor and the performance by the Guarantor of its obligations thereunder (including with respect to the Exchange Guarantee) do not and will not conflict with or result in a violation of such Guarantor’s (i) the articles of incorporation or bylaws or (ii)  any statute or governmental rule or regulation of the State of Mississippi or any political subdivision thereof and (C) no consent of any State of Mississippi court or governmental authority is required for the issuance by such Guarantor of the Exchange Guarantee.

None of the opinions or other advice contained in this letter considers or covers any foreign or state securities (or “blue sky”) laws or regulations.

     This opinion is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. We assume no obligation to revise or supplement this opinion after the date of effectiveness of the Registration Statement should the present laws of the States of New York or Delaware be changed by legislative action, judicial decision or otherwise.

     This opinion is furnished to you in connection with the filing of the Registration Statement in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.
