Exhibit 4.7

among

and

the WARRANTHOLDERS NAMED HEREIN

Dated as of December 21, 2004

REGISTRATION RIGHTS AGREEMENT, dated as of December 21, 2004 (the “Agreement”), among TERRA INDUSTRIES INC., a Maryland corporation (the “Company”) and the warrantholders named on the signature pages hereto or who become a party to this Agreement subsequent to the date hereof (each referred to as a “Warrantholder” and collectively as “Warrantholders”). Certain capitalized terms are defined in Section 8 hereof.

WHEREAS the Warrantholders have requested the Company to take certain steps to facilitate the sale to the public of certain warrants and common shares, without par value, of the Company (“Shares”) and the Company believes that it is consistent with the Company’s commercial objectives to do so.

NOW, THEREFORE, in consideration of the premises, representations and agreements contained herein, the parties agree as follows:

1. Shelf Registration Statement.

(a) Filing; Effectiveness. The Company shall:

(i) use best efforts to file no later than 60 days following the date of this Agreement an “evergreen” shelf registration statement on Form S-3 (the “Shelf Registration”) pursuant to Rule 415 under the United States Securities Act of 1933, as amended (the “Securities Act”), providing for an offering to be made on a continuous basis of the Registrable Securities;

(ii) use commercially reasonable efforts to cause the Shelf Registration to become effective as soon as practicable after such filing;

(iii) subject to Section 1(c), use commercially reasonable efforts to maintain in effect, supplement and amend, if necessary, the Shelf Registration, as required by the instructions applicable to such registration form or by the Securities Act or as reasonably requested by a holder of Registrable Securities; and

(iv) furnish to the holders of Registrable Securities copies of any supplement or amendment to such Shelf Registration after the close of business one business day prior to such supplement, amendment or document being used and/or filed with the United States Securities and Exchange Commission (the “Commission”).

(b) Shelf Registration Procedures.

(i) If at any time the Shelf Registration ceases to be effective, then the Company shall use its best efforts to file and use its commercially reasonable efforts to cause to become effective a new “evergreen” shelf registration statement as promptly as practicable.

(ii) If, after the Shelf Registration has become effective, any stop order, injunction or other order or requirement of the Commission or other governmental agency or authority is threatened, then the Company shall use its commercially reasonable efforts to

prevent the issuance of any order suspending the effectiveness of the Shelf Registration or of any order preventing or suspending the use of any preliminary prospectus and, if any such order is issued, to obtain the withdrawal of any such order as soon as reasonably practicable.

(c) (i) The Company may at any time furnish to the holders of Registrable Securities a certificate signed by its chairman of the board, president, chief executive officer, chief financial officer or general counsel (a “Suspension Notice”) stating that in his or her good faith judgment following consultation with the Company’s outside securities counsel, the filing of an amendment or supplement to the Shelf Registration or a document incorporated by reference therein is necessary in order to ensure that the Shelf Registration conforms in all material respects to the requirements of the Securities Act and does not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Except to the extent required by law, each holder of Registrable Securities shall keep confidential and not disclose the fact that it has received a Suspension Notice; the Company agrees that any such Suspension Notice shall provide only that a suspension is in effect and shall not include any material non-public information regarding the cause for the issuance of such Suspension Notice. Upon receipt of a Suspension Notice, each holder of Registrable Securities receiving such notice shall immediately cease selling Registrable Securities pursuant to the Shelf Registration and shall discontinue use of any prospectus contained in the Shelf Registration until such holder of Registrable Securities has received written notice from the Company pursuant to Section 1(c)(iv) that the Suspension Notice is no longer in effect.

(ii) If at any time prior to the initial filing of a Shelf Registration the Company shall furnish a Suspension Notice to the holders of Registrable Securities pursuant to Section 1(c)(i), the Company may postpone the filing (but not the preparation) of the Shelf Registration for not more than 45 days upon prior notice of such postponement to the applicable holders of Registrable Securities; provided, however, that the Company shall not be permitted to postpone registration pursuant to this clause (c)(ii) more than once with respect to any Shelf Registration.

(iii) Following the effectiveness of the Shelf Registration, the Company shall be obligated to deliver to the holders of Registrable Securities with Shares registered thereunder a Suspension Notice immediately upon discovery by the Company of any condition of the type specified in Section 1(c)(i). The Company shall use commercially reasonable efforts to supplement and amend, if necessary, as promptly as practicable the Shelf Registration such that the Shelf Registration, as amended or supplemented, conforms in all material respects to the requirements of the Securities Act and does not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Company shall not be obligated to supplement or amend the Shelf Registration if the board of directors of the Company determines in good faith following consultation with the Company’s outside securities counsel that the Company has pending or in process a material transaction, the disclosure of which would materially and adversely affect the Company or the market for its securities, or the Company has undisclosed material information that the Company has a bona fide business purpose for preserving as confidential and which in each case would be required by the securities laws to be disclosed in the Shelf Registration; provided, further, that (i) the Company shall be entitled to

exercise such right pursuant to the foregoing proviso no more than twice in any period of 12 consecutive months and for no more than 90 days in any period of 12 consecutive months and (ii) the Company shall not be entitled to exercise such right during the 60 days following the effective date of the Shelf Registration.

(iv) The Company shall be obligated to promptly notify the holders of Registrable Securities with Shares registered under a Shelf Registration in writing once (A) the Shelf Registration has been supplemented or amended, including by the filing of a document incorporated therein by reference, in a manner that has corrected the condition that was the subject of such Suspension Notice or (B) the Suspension Notice is otherwise no longer in effect due to the cessation of the condition that was the subject of such Suspension Notice.

2. Piggyback Registrations.

(a) Right to Piggyback. Whenever the Company proposes to register any of its securities under the Securities Act and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give prompt written notice to all holders of Registrable Securities of its intention to effect such a registration and, subject to the terms of Sections 2(b) and 2(c) hereof, shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 30 days after the date of the Company’s notice.

(b) Priority on Primary Registrations. If a Piggyback Registration is an underwritten registration, and the managing underwriters in good faith advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Company, (the “Company Acceptable Price Range”), the Company shall include in such registration the maximum number of securities which in the opinion of such underwriters can be sold in an orderly manner within the Company Acceptable Price Range according to the following priority:

(i) First, securities held by any Persons having contractual, incidental “piggy back” registration rights granted prior to the date hereof pursuant to an agreement which is not this Agreement.

(ii) Second, Registrable Securities sought to be included by the Warrantholders as determined on a pro rata basis (based upon the aggregate number of Registrable Securities held by such Warrantholders).

(iii) Third, to such other securities as the Company may permit.

(c) With respect to clause (ii) of Section 2(b), each Warrantholder may sell a pro rata share of the Warrantholder’s allotment in proportion to such Warrantholder’s ownership of Registrable Securities at the time of such underwritten registration (after deducting from the Registrable Securities the Shares, if any, held by any Warrantholder not participating in such underwritten registration).

3. Registration Expenses.

(a) The Company shall pay all reasonable and documented “out of pocket” expenses arising from the preparation and initial filing of the Shelf Registration and all amendments or commitments thereto required for effectiveness, including, without limitation, (a) all Commission and any National Association of Securities Dealers registration and filing fees and expenses, (b) all fees and expenses in connection with the qualification of the Registrable Securities (or any Shares being offered by the Company) for offering and sale under the state securities and blue sky laws, including reasonable fees and qualifications, (c) all expenses relating to the preparation, printing, distribution and reproduction of the Shelf Registration, each prospectus included therein or prepared for distribution pursuant hereto, each amendment or supplement to the foregoing, the certificates representing the Common Shares or other equity securities to be sold and all other documents relating hereto, (d) fees and expenses of any escrow agent or custodian, (e) fees, disbursements and expenses of counsel and independent certified public accountants of the Company and (f) all fees and expenses (including listing and qualification fees) in connection with the listing or admission to quotation of the Registrable Securities (or any Shares being offered by the Company). All of the expenses described in the preceding sentence of this Section 3(a) are referred to herein as “Registration Expenses.” Each holder of Registrable Securities included in any registration hereunder (including the Company in the case of a Piggyback Registration) shall bear the expense of any broker’s commission or underwriter’s discount or commission relating to registration and sale of such holder’s Registrable Securities.

4. Registration Procedures.

In connection with any registration hereunder, the Company will:

(a) furnish to each selling holder and the underwriters, if any, such number of copies of such registration statement, any amendments thereto, any documents incorporated by reference therein, the prospectus, including a preliminary prospectus in conformity with the requirements of the Securities Act, and such other documents as such selling holder or underwriters may reasonably request in order to facilitate the public sale or other disposition of the securities owned by such selling holder;

(b) file and use its commercially reasonable efforts to register or qualify the securities covered by such registration statement under such other securities or state securities or “blue sky” laws of such jurisdictions as each selling holder shall request, and do any and all other acts and things that may be necessary under such state securities or “blue sky” laws to enable such selling holder to consummate the public sale or other disposition in such jurisdictions of the securities owned by such selling holder, except that the Company shall not for any such purpose be required to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified;

(c) if reasonably requested by the managing underwriter or underwriters (if any), any selling holder, or such selling holder’s counsel, promptly incorporate into a prospectus supplement or post-effective amendment such information as such person requests to be included therein, including, without limitation, with respect to the securities being sold by such selling

holder to such underwriter or underwriters, the purchase price being paid therefor by such underwriter or underwriters and any other terms of an underwritten offering of the securities to be sold in such offering, and promptly make all required filings of such prospectus supplement or post-effective amendment;

(d) cause the securities covered by such registration statement to be listed on the national securities exchange or quoted on the quotation system on which the Shares are then listed or quoted;

(e) otherwise cooperate with the underwriter(s), the Commission and other regulatory agencies and take all actions and execute and deliver or cause to be executed and delivered all documents reasonably necessary to effect the offering and sale of the Registrable Securities as contemplated hereunder; and

(f) provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a CUSIP number for all such Registrable Securities, in each case no later than the effective date of such registration.

5. Representations and Warranties by the Company.

The Company represents and warrants to, and agrees with, each holder of Registrable Securities that:

(a) each registration statement, as supplemented or amended, covering Registrable Securities at its effective date and each prospectus (including any preliminary prospectus) as of the date of such prospectus, or, in the case of an underwritten offering of Registrable Securities, at the time of the closing under the underwriting agreement related thereto, will conform in all material respects to the requirements of the Securities Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and at all times subsequent to the effective date of such registration statement when a prospectus would be required to be delivered under the Securities Act, other than from such time as the Company has delivered a Suspension Notice to such holder of Registrable Securities pursuant to Section 1(c) until such time as the Company has delivered a notice withdrawing such Suspension Notice to such holder of Registrable Securities, each such registration statement and each prospectus contained therein, as then amended or supplemented, will conform in all material respects to the requirements of the Securities Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein;

(b) the compliance by the Company with all of the provisions of this Agreement and the consummation of the transactions herein contemplated will not (i) conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the

Company or any subsidiary is a party or by which the Company or any subsidiary is bound or to which any of the property or assets of the Company or any subsidiary is subject, or (ii) result in any violation of the provisions of the Articles of Incorporation or By-Laws of the Company as currently in effect or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any subsidiary or any of their properties; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the consummation by the Company of the transactions contemplated by this Agreement, except the registration under the Securities Act of the Registrable Securities and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or blue sky laws in connection with the offering and distribution of the Registrable Securities.

6. Indemnification.

(a) The Company agrees to indemnify, to the extent permitted by law, each holder of Registrable Securities, its officers, directors, partners, employees and agents and each person who controls such holder (within the meaning of the Securities Act) against all losses, claims, actions, damages, liabilities and expenses caused by (i) any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act or any other similar federal or state securities laws or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and to pay to each holder of Registrable Securities, its officers, directors, partners, employees and agents and each person who controls such holder (within the meaning of the Securities Act), as incurred, any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, except insofar as (i) the same are caused by or contained in any information furnished in writing to the Company by such holder expressly for use therein, (ii) by such holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same, or (iii) such holder’s failure to comply with Section 1(c) hereof.

(b) In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, its directors, officers, partners, employees and agents and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from (i) any untrue or alleged untrue statement of material fact contained in the registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such holder, (ii) such holder’s failure to deliver a copy of the

registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient number of copies of the same, or (iii) such holder’s failure to comply with Section 1(c) hereof.

(c) Any person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicting indemnified parties shall have a right to retain one separate counsel, chosen by the holders of a majority of the Registrable Securities included in the registration, at the expense of the indemnifying party.

7. Termination.

(a) This Agreement may be terminated at any time by written consent by each of the parties hereto. Subject to Section 8(d), this Agreement shall be terminated automatically with respect to a holder of Registrable Securities upon the sale, transfer, assignment or other disposal by such holder of all of such holder’s Registrable Securities. The Shares held by any holder of Registrable Securities shall cease to constitute Registrable Securities at such time as such Shares may be sold pursuant to Rule 144 (or any successor rule) under the Securities Act in a single transaction.

(b) Upon termination of this Agreement none of the parties shall have any further liability hereunder, except with respect to Section 6 hereof.

8. Definitions.

(a) “Affiliate” has the meaning set forth in the Securities Act.

(b) “Person” shall mean an individual, a corporation, a partnership, a joint venture, a trust, an unincorporated organization, a limited liability company or partnership, a government and any agency or political subdivision thereof.

(c) “Registrable Securities” means (i) the Warrants and (ii) the four million (4,000,000) Shares issuable upon exercise of the Warrants and any Shares issued or issuable with respect to any such Shares by way of a stock

dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization.

(d) “Warrants” means the warrants granted to Perry Principals Investments LLC., Citigroup Global Markets, Inc. and Värde Investment Partners, LP by the Company on the date hereof to acquire four million (4,000,000) Shares.

9. Miscellaneous.

(a) Listing of Warrants. The Company shall use its commercially reasonable efforts to cause the Warrants to be listed on the national securities exchange or quoted on the quotation system on which the common shares of the Company are then listed or quoted.

(b) Lock-Up. If advised by the relevant lead underwriter that a lock-up is, in the good faith determination of such lead underwriter, advisable in connection with an underwritten primary offering by the Company (other than pursuant to a registration statement on Form S-8), each holder of Registrable Securities agrees (and no holder of Registrable Securities or other Company securities will be permitted to agree separately with the Company or any underwriter for more favorable lock-up terms) to cease sales of all other securities of the Company (other than any securities included in the registration statement relating to such primary offering) until (i) the earlier of (A) the expiration of the period of time (not to exceed 90 days) so requested by the lead underwriter; and (B) termination of the offering efforts.

(c) No Inconsistent Agreements. The Company represents, warrants, covenants and agrees that (i) it has not granted, and shall not grant, registration rights with respect to any Shares, Registrable Securities or any other securities that would be inconsistent with the terms contained in this Agreement and (ii) it shall not grant to any Person any contractual, incidental “piggy back” registration rights with a priority equal to or more favorable than granted to the Warrantholders pursuant to Section 2 hereunder. The Company further represents and warrants that, in the event it grants any person registration rights at any time within the six months following the effective date of the Shelf Registration, the holders of Registrable Securities shall be entitled to participate on a pro rata basis in any such registrations.

(d) Specific Performance. The parties hereto acknowledge that there would be no determinable amount of damages and no adequate remedy at law if the Company breached any of the provisions and obligations of the Agreement and that the holders of Registrable Securities from time to time may be irreparably harmed. The parties hereto agree that the holders of Registrable Securities, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of the Company under this Agreement in any court having jurisdiction.

(e) Notices. All notices, requests, claims or demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered by hand, when delivered personally or by courier, three days after being dispatched by express courier, or when received by facsimile transmission if promptly confirmed by foregoing

(f) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(g) Arbitration. The parties irrevocably agree that any dispute arising out of or relating to this Agreement shall be settled by arbitration between the parties in accordance with the arbitration rules of the International Chamber of Commerce (“ICC”) as in effect at the time of submission of the dispute to such arbitration. Such arbitration shall be the exclusive method for resolution of the dispute, and the determination of the arbitrators shall be final and binding. The costs of the arbitration, and the reasonable and related legal and other costs of the party prevailing in the arbitration, shall be borne by the party who does not prevail. The arbitral award shall specify which such party or parties is the “prevailing party” for this purpose. The number of arbitrators shall be three.

This Agreement does not set forth, and should not be implied to create, any agreement or understanding between or among any holders of Registrable Securities as to any matters (other than with respect to the payment of Registration Expenses). This Agreement supersedes all prior agreements and understandings

between the parties with respect to its subject matter. This Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument duly executed by the Company and the holders of a majority of the Registrable Securities, unless (i) such amendment or waiver disproportionately affects the rights of any class of Registrable Securities, in which case such amendment or waiver shall require the written consent of the holders of a majority of such class of Registrable Securities or (ii) such amendment or waiver disproportionately affects the rights of any holder of Registrable Securities, in which case such amendment or waiver shall require the written consent of such holder.

(k) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
