(vi)                              The Issuer shall have received (A) counterparts of a Canadian Mortgage with respect to each Canadian Mortgaged Property duly executed and delivered by the registered owner of such Canadian Mortgaged Property, (B) a policy or policies of title insurance by a nationally recognized title insurance company insuring the charge of each such Canadian Mortgaged Property as a valid first-priority charge on the Canadian Mortgaged Property described therein, free of any other encumbrances (but subject to liens or other encumbrances for which exceptions are taken in the policies of title insurance delivered in respect of the Canadian Mortgaged Properties and subject to liens permitted under the Indenture and the Canadian Collateral Agreement), together with such endorsements, coinsurance and reinsurance as the Issuer may reasonably request, and (C) such surveys, abstracts, appraisals, legal opinions and other documents as the Issuer may reasonably request with respect to any such Canadian Mortgage or Canadian Mortgaged Property.

(vii)                           All filing fees, taxes and other amounts payable in connection with the filings, recordings, registrations and other actions described in clauses (i) through (vi) above shall have been paid or payment by Novamerican Steel provided for to the reasonable satisfaction of the Representative and the Canadian Collateral Agent.

(r)                                    Perfection Certificate. On or prior to the Closing Date, the Representative shall have received (i) a completed perfection certificate in the form attached to the Collateral Agreement to be dated as of the Closing Date (the “Perfection Certificate”), executed by an executive officer of Symmetry, the Issuer and Novamerican Steel, together with all attachments contemplated thereby, which shall be correct and complete as of the Closing Date, and (ii) the

30

results of lien searches, conducted by a search service reasonably satisfactory to the Representative, and the Representative shall be satisfied that no liens are outstanding on the property or assets of the Issuer, Novamerican Steel or any of the Guarantors, other than any such liens (A) which constitute Permitted Liens (as defined in the Indenture) or (B) as to which the Initial Purchasers have received documentation reasonably satisfactory to it evidencing the termination of such liens.

All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers.

7.                                       Indemnification and Contribution.

(a)                                  Indemnification of the Initial Purchasers. The Issuer and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Issuer in writing by such Initial Purchaser through the Representative expressly for use therein.

(b)                                 Indemnification of the Issuer. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Issuer, each of the Guarantors, each of their respective directors and officers and each person, if any, who controls the Issuer or any of the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Issuer in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the fifth and sixth sentences of the tenth paragraph and the first and last sentences of the twelfth paragraph under the caption “Plan of Distribution” in the Preliminary Offering Memorandum; provided that none of the Initial Purchasers shall have any obligations pursuant to this paragraph (b) with respect to any Guarantor that is a Joining Party, its affiliates, directors and each person,

31

if any, who controls such Guarantor until the Joinder Agreement is executed and delivered pursuant to Section 6(n) hereof.

(c)                                  Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably been advised by counsel that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by ▇.▇. ▇▇▇▇▇▇ Securities Inc. and any such separate firm for the Issuer, the Guarantors, their respective directors and officers and any control persons of the Issuer and the Guarantors shall be designated in writing by the Issuer. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person

32

in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)                                 Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuer from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer or any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)                                  Limitation on Liability. The Issuer, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the

33

Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)                                    Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8.                                       Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Issuer, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Issuer, NSI or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery, of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.

9.                                       Defaulting Initial Purchaser. (a)  If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Issuer on the terms contained in this Agreement. If, within 24 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Issuer shall be entitled to a further period of 24 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Issuer may postpone the Closing Date for up to three full business days in order to effect any changes that in the opinion of counsel for the Issuer or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Issuer agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b)                                 If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuer shall have the right to require each non-defaulting Initial Purchaser to

34

purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c)                                  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuer shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Issuer, NSI or the Guarantors, except that the Issuer and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d)                                 Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Issuer, its affiliates or any non-defaulting Initial Purchaser for damages caused by its default.

10.                                 Payment of Expenses. (a)  Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Issuer and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and, as applicable, the Exchange Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Issuer’s, NSI’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related reasonable fees and expenses of one counsel for the Initial Purchasers in connection therewith); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the application for the inclusion of the Securities on the PORTAL Market and the approval of the Securities for book-entry transfer by DTC; (ix) all expenses incurred by the Issuer in connection with any “road show” presentation to potential investors; and (x) the costs of creating and perfecting the security interests as contemplated by the Security Agreements (including the related reasonable costs of counsel for the Initial Purchasers in connection therewith) and the fees and expenses of the Collateral Agents (including the reasonable fees and expenses of their professional advisors). It is understood, however, that except as provided in this Section, Section 7 and Section 9, the Initial Purchasers will pay all of their costs and

35

expenses, including the fees and expenses of their counsel and any advertising expenses connected with any offers they may make.

(b)                                 If (i) this Agreement is terminated pursuant to Section 8, (ii) the Issuer for any reason fails (other than by reason of a breach of this Agreement by the Initial Purchasers) to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Issuer and each of the Guarantors jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

11.                                 Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon (a) the parties hereto and their respective successors and any controlling persons referred to herein and (b)(i) the affiliates, officers and directors of each Initial Purchaser and (ii) the officers and directors of the Issuer and each of the Guarantors, in the case of clauses (b)(i) and (b)(ii) above, referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

12.                                 Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Issuer, Novamerican Steel and each of the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Issuer, Novamerican Steel, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Issuer, Novamerican Steel, the Guarantors or the Initial Purchasers.

13.                                 Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “Exchange Act” means the Securities Exchange Act of 1934, as amended; (d) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (e) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.

14.                                 Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (the “Related Proceedings”) may be instituted in the federal courts of the United States located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (each such judgment, a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such

36

party’s address set forth below shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation System as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified Court.

15.                                 Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts and, with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

16.                                 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers could purchase U.S. dollars with such other currency in New York City on the business day preceding that on which final judgment is given. The obligations of the Issuer, Novamerican Steel and each Guarantor in respect of any sum due from them to any Initial Purchaser shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Initial Purchaser of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Initial Purchaser may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Initial Purchaser hereunder, the Issuer, Novamerican Steel and each Guarantor agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Initial Purchaser against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Initial Purchaser hereunder, such Initial Purchaser agrees to pay to the Issuer, Novamerican Steel and the Guarantors (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Initial Purchaser hereunder.

17.                                 Miscellaneous. (a)  Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by ▇.▇. ▇▇▇▇▇▇ Securities Inc. on behalf of the Initial Purchasers, and any such action taken by ▇.▇. ▇▇▇▇▇▇ Securities Inc. shall be binding upon the Initial Purchasers.

Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Initial Purchasers shall be given to the Representative c/o ▇.▇. ▇▇▇▇▇▇ Securities Inc., ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (fax:  (▇▇▇)-▇▇▇-▇▇▇▇);

(b)                                 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

(c)                                  Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

(d)                                 Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

Pricing Term Sheet

Capitalized terms used but not defined in this term sheet have the meanings assigned to such terms in the Issuer’s Preliminary Offering Memorandum dated October 29, 2007 (the “Preliminary Offering Memorandum”).

The notes have not been registered under the U.S. Securities Act of 1933, as amended, and are being offered only to qualified institutional buyers under Rule 144A and outside the United States in compliance with Regulation S.

This term sheet is qualified in its entirety by reference to the Preliminary Offering Memorandum. The information in this term sheet supplements the Preliminary Offering Memorandum and supersedes the information in the Preliminary Offering Memorandum to the extent inconsistent with the information in the Preliminary Offering Memorandum.

ANNEX A

Certain U.S. federal income tax consequences

To ensure compliance with Internal Revenue Service Circular 230, you are hereby notified that any discussion of tax matters set forth in this offering memorandum was written in connection with the promotion or marketing of the transactions or matters addressed herein and was not intended or written to be used, and cannot be used by any prospective investor, for the purpose of avoiding tax-related penalties under federal, state or local tax law. Each prospective investor should seek advice based on its particular circumstances from an independent tax advisor.

The following is a summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of the notes as of the date hereof. Except where noted, this summary deals only with notes that are held as capital assets by holders who purchase the notes for cash upon original issuance at their initial offering price. As used herein, a “U.S. holder” means a beneficial owner of the notes that is for U.S. federal income tax purposes any of the following:

•                                          an individual citizen or resident of the United States;

•                                          a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•                                          an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•                                          a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

The term “non-U.S. holder” means a beneficial owner of the notes (other than a partnership or any other entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder.

This summary does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are a person subject to special tax treatment under the U.S. federal income tax laws, including, without limitation:

•                                          a dealer in securities or currencies;

•                                          a financial institution;

•                                          a regulated investment company;

•                                          a real estate investment trust;

•                                          a tax-exempt organization;

•                                          an insurance company;

•                                          a person holding the notes as part of a hedging, integrated, conversion or constructive sale transaction or a straddle;

•                                          a trader in securities that has elected the ▇▇▇▇-to-market method of accounting for your securities;

•                                          a person liable for alternative minimum tax;

•                                          a partnership or other pass-through entity for U.S. federal income tax purposes;

•                                          a U.S. holder whose “functional currency” is not the U.S. dollar;

•                                          a controlled foreign corporation;

•                                          a passive foreign investment company; or

•                                          a U.S. expatriate.

This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), United States Treasury regulations, administrative rulings and judicial decisions as of the date hereof. Those authorities may be changed, possibly on a retroactive basis, so as to result in U.S. federal income tax consequences different from those summarized below.

If a partnership (including any entity classified as a partnership for U.S. federal income tax purposes) holds notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership holding notes, you should consult your own tax advisors.

This summary does not represent a detailed description of the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the effects of any state, local or non-United States tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular purchaser of notes. If you are considering the purchase of notes, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the ownership of the notes, as well as the consequences to you arising under the laws of any other taxing jurisdiction.

Certain tax consequences to U.S. holders

The following is a summary of certain U.S. federal income tax consequences that will apply to U.S. holders of the notes.

Payments of interest

Except as set forth below, qualified stated interest on a note will generally be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for tax purposes. If the notes are not issued with more than a de minimis amount at original issue discount (“OID”), as described below, all the interest payable on the notes will be qualified stated interest.

Original issue discount

Depending upon the issue price of the notes, the notes may be issued with OID in an amount equal to the difference between their “stated redemption price at maturity” (the sum of all payments to be made

on the notes other than “qualified stated interest”) and their “issue price.” You should be aware that you generally must include OID in gross income in advance of the receipt of cash attributable to that income. OID is considered de minimis if the total OID is less than twenty-five basis points (.25%), multiplied by the number of full years from the issue date to the maturity date of the Note. However, you generally will not be required to include separately in income cash payments received on the notes, even if denominated as interest, to the extent such payments do not constitute “qualified stated interest” (as defined below).

This summary is based upon final Treasury regulations addressing debt instruments issued with OID.

The “issue price” of each note will be the first price at which a substantial amount of that particular offering is sold (other than to an underwriter, placement agent or wholesaler). The term “qualified stated interest” means stated interest that is unconditionally payable in cash or in property (other than debt instruments of the issuer), and meet all of the following conditions:

•                                          it is payable at least once per year;

•                                          it is payable over the entire term of the note; and

•                                          it is payable at a single fixed rate or, subject to certain conditions, based on one or more interest indices.

The stated interest payments on the notes are qualified stated interest.

The amount of OID that you must include in income if you are the initial U.S. holder of a note is the sum of the “daily portions” of OID with respect to the note for each day during the taxable year or portion of the taxable year in which you held such note (“accrued OID”). The daily portion is determined by allocating to each day in any “accrual period” a pro rata portion of the OID allocable to that accrual period. The “accrual period” for a note may be of any length and may vary in length over the term of the note, provided that each accrual period is no longer than one year and each scheduled payment of principal or interest occurs on the first day or the final day of an accrual period. The amount of OID allocable to any accrual period is an amount equal to the excess, if any, of:

•                                          the product of the note’s adjusted issue price at the beginning of such accrual period and its yield to maturity (determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of the accrual period), over

•                                          the aggregate of all qualified stated interest allocable to the accrual period.

OID allocable to a final accrual period is the difference between the amount payable at maturity (other than a payment of qualified stated interest) and the adjusted issue price at the beginning of the final accrual period. Special rules will apply for calculating OID for an initial short accrual period. The “adjusted issue price” of a note at the beginning of any accrual period is equal to its issue price increased by the accrued OID for each prior accrual period and reduced by any payments made on such note (other than qualified stated interest) on or before the first day of the accrual period. Under these rules, you will have to include in income increasingly greater amounts of OID in successive accrual periods. We are required to provide information returns stating the amount of OID accrued on notes held of record by persons other than corporations and other exempt holders.

You may elect to treat all interest on a note as OID and calculate the amount includible in gross income under the constant yield method described above. The election is to be made for the taxable

year in which you acquired the note, and may not be revoked without the consent of the Internal Revenue Service (“IRS”). You should consult with your own tax advisors about this election.

Sale, exchange, retirement, or other taxable disposition of notes

Upon the sale, exchange, retirement, or other taxable disposition of a note, you generally will recognize gain or loss equal to the difference between the amount realized upon the sale, exchange, retirement, or other taxable disposition (less an amount equal to any accrued qualified stated interest that you did not previously include in income, which will be taxable as interest income) and the adjusted tax basis of the note. Your adjusted tax basis in a note will, in general, be your cost for the note increased by the amount of OID, if any  previously included in income.

Any gain or loss you recognize will be capital gain or loss and will be long-term capital gain or loss if at the time of sale, exchange, retirement or other disposition, the note has been held for more than one year. Capital gains of noncorporate U.S. holders (including individuals) derived with respect to capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Certain tax consequences to non-U.S. holders

The following is a summary of certain U.S. federal income tax consequences that will apply to non-U.S. holders of notes.

U.S. federal withholding tax

The 30% U.S. federal withholding tax will not apply to any payment of interest (including OID, if applicable) on the notes under the “portfolio interest rule,” provided that:

•                                          interest paid on the notes is not effectively connected with your conduct of a trade or business in the United States;

•                                          you do not actually (or constructively) own 10% or more of the total combined voting power of all classes of our voting stock within the meaning of the Code and applicable United States Treasury regulations;

•                                          you are not a controlled foreign corporation that is related to us actually or constructively through stock ownership;

•                                          you are not a bank whose receipt of interest on the notes is described in Section 881(c)(3)(A) of the Code; and

•                                          either (a) you provide your name and address on an IRS Form W-8BEN (or other applicable form), and certify, under penalties of perjury, that you are not a United States person as defined under the Code or (b) you hold your notes through certain foreign intermediaries and satisfy the certification requirements of applicable United States Treasury regulations. Special certification rules apply to non-U.S. holders that are pass-through entities rather than corporations or individuals.

If you cannot satisfy the requirements described above, payments of interest (including OID, if applicable) made to you will be subject to the 30% U.S. federal withholding tax, unless you provide us with a properly executed:

•                                          IRS Form W-8BEN (or other applicable form) certifying an exemption from or reduction in withholding under the benefit of an applicable income tax treaty; or

•                                          IRS Form W-8ECI (or other applicable form) certifying interest paid on the notes is not subject to withholding tax because it is effectively connected with your conduct of a trade or business in the United States (as discussed below under “—U.S. federal income tax”).

The 30% U.S. federal withholding tax generally will not apply to any payment of principal or gain that you realize on the sale, exchange, retirement or other disposition of a note.

U.S. federal income tax

If you are engaged in a trade or business in the United States and interest (including OID, if applicable) on the notes is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment), then you will be subject to U.S. federal income tax on that interest (including OID, if applicable)on a net income basis (although you will be exempt from the 30% U.S. federal withholding tax, provided the certification requirements discussed above in “—U.S. federal withholding tax” are satisfied) in generally the same manner as if you were a United States person as defined under the Code. In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or lower applicable income tax treaty rate) of such interest (including OID, if applicable), subject to adjustments.

Any gain realized on the disposition of a note generally will not be subject to U.S. federal income tax unless:

•                                          the gain is effectively connected with your conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment); or

•                                          you are an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met.

Information reporting and backup withholding

U.S. holders

In general, information reporting requirements will apply to certain payments of principal and interest (including OID, if applicable) paid on the notes and to the proceeds of the sale or other disposition of a note paid to you (unless you are an exempt recipient such as a corporation). Backup withholding may apply to such payments if you fail to provide a taxpayer identification number or a certification that you are not subject to backup withholding, or if you fail to report in full dividend and interest income.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Non-U.S. holders

Generally, we must report to the IRS and to you the amount of interest (including OID, if applicable) paid to you and the amount of tax, if any, withheld with respect to those payments. Copies of the

information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable income tax treaty.

In general, you will not be subject to backup withholding with respect to payments of interest (including OID, if applicable) on the notes that we make to you provided that we do not have actual knowledge or reason to know that you are a United States person as defined under the Code, and we have received from you the required certification that you are a non-U.S. holder described above in the fifth bullet point under “—Certain tax consequences to non-U.S. holders—U.S. federal withholding tax.”

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale or other disposition (including a redemption) of notes within the United States or conducted through certain United States-related financial intermediaries, unless you certify to the payor under penalties of perjury that you are a non-U.S. holder (and the payor does not have actual knowledge or reason to know that you are a United States person as defined under the Code), or you otherwise establish an exemption.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

each of the Guarantors with the terms thereof and the consummation by them of the transactions contemplated by the Transaction Documents on their part to be consummated, except for such consents, approvals, authorizations, orders and registrations or qualifications (i) as may be required under applicable state securities laws in connection with the purchase and resale of the Securities (including the Guarantees) by the Initial Purchasers, (ii) as may be required with respect to the Exchange Securities (including the related guarantees) under the Securities Act and applicable state securities laws as contemplated by the Registration Rights Agreement or (iii) to the extent that the failure to obtain a consent, approval, authorization, order, registration or qualification, in each case related solely to the consummation of the Acquisition and not to any financing transactions (including the offering and sale of the Securities) related thereto, would not, individually or in the aggregate, have a Material Adverse Effect.

(17)                            To our knowledge, except as described in each of the Time of Sale Information and the Offering Memorandum, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending to which Symmetry or any of the Post Transaction Subsidiaries is or might reasonably be expected to be a party or to which any property of Symmetry or any of the Post Transaction Subsidiaries is or may be the subject that we believe, individually or in the aggregate, if determined adversely to Symmetry or any of the Post Transaction Subsidiaries, would reasonably be expected to have a Material Adverse Effect; and to our knowledge, no such investigations, actions, suits or proceedings are threatened or contemplated by any governmental or regulatory authority or threatened by others.

(20)                            Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Issuer as described in each of the Time of Sale Information and the Offering Memorandum will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System.

(21)                            Assuming the accuracy of the representations, warranties and agreements of Symmetry, the Issuer, Novamerican Steel, the Guarantors and the Initial Purchasers contained in the Purchase Agreement and the Joinder Agreement, it is not necessary, in connection with the issuance and sale of the Securities to the Initial Purchasers and the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the Time of Sale Information and the Offering Memorandum, to register the Securities under the

4

Securities Act or to qualify the Indenture under the Trust Indenture Act, it being understood that no opinion is expressed as to any subsequent resale of any of the Securities.

(22)                            The Collateral Agreement is effective to create in favor of the U.S. Collateral Agent, for the benefit of the Secured Parties, a security interest in the Collateral described therein in which a security interest may be created under Article 9 of the New York UCC.

(23)                            Upon delivery to the U.S. Collateral Agent in the State of New York of all certificates evidencing the Pledged Securities described on Annex C hereto (such certificates, the “Certificates”), issued or endorsed in the name of the U.S. Collateral Agent or in blank or together with stock powers or note powers properly executed in the name of the U.S. Collateral Agent or in blank, the security interest in such Pledged Securities described on Annex C hereto in favor of the U.S. Collateral Agent, for the benefit of the Secured Parties, will be perfected and assuming that the U.S. Collateral Agent has taken possession of the Certificates and such accompanying endorsements or powers without notice, at or prior to the time of delivery thereof to the U.S. Collateral Agent, of any adverse claim within the meaning of Section 8-102(a)(i) of the New York UCC, the U.S. collateral Agent has acquired a security interest in such Pledged Securities free of any adverse claim.

(25)                            In any proceeding in a court of competent jurisdiction in the Province of Ontario (an “Ontario Court”) for the enforcement of the Transaction Documents(13), the Ontario Court would apply the laws of the State of New York (“New York Law”), in accordance with the parties’ choice of New York Law in the Transaction Documents, to all issues which under the conflict of laws rules of the Province of Ontario are to be determined in accordance with the proper law of a contract, provided that:

(a)                                  the parties’ choice of New York Law in the Transaction Documents is bona fide and legal and there is no reason for avoiding the choice on the grounds of public policy, as such criteria would be applied by the Ontario Court; and

(b)                                 in any such proceeding, and notwithstanding the parties’ choice of New York Law in the Transaction Documents, the Ontario Court:

(26)                            An Ontario Court would give a judgment based upon a final and conclusive in personam judgment of a court exercising jurisdiction in the State of New York (a “New York Court”) for a sum certain, obtained against the Corporation with respect to a claim arising out of the Transaction Documents (a “New York Judgment”), without reconsideration of the merits(14):

(a)                                  provided that:

(13)    This opinion should be limited to documents governed by New York law.

(14)    This opinion should be limited to documents where there is submission to a New York court.

4

(27)                            In any proceeding in a court of competent jurisdiction in the Province of Québec (a “Québec Court”) for the enforcement of the Transaction Documents, the Québec Court would recognize the choice of New York Law as the proper law governing the Transaction Documents as chosen by the parties therein and apply such law to issues which under conflict of law rules of Québec are to be dealt with in accordance with the governing law of the Transaction Documents, provided that(15):

(c)                                  such choice of law is bona fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction) and such choice of law is not manifestly inconsistent with public order, as that term is understood in international relations by a Québec Court (Article 3081 C.C.Q.); and

(d)                                 in any such proceeding, and notwithstanding the parties’ choice of New York Law:

(15) This opinion should be limited to documents governed by New York law.

5

(28)                            Upon a motion brought before it, a Québec Court would recognize and declare enforceable a final and enforceable civil judgment in personam, not subject to ordinary remedy, for a sum certain of a New York Court against the parties to the Transaction Documents in connection with an action arising out of said Transaction Documents if(16):

(e)                                  the New York Court rendering such judgment had jurisdiction, as recognized by the Québec Court (Article 3155(1) C.C.Q.);

(f)                                    such judgment was not obtained by fraud or in a manner contrary to natural justice or in contravention of the fundamental principles of procedure (Article 3155(3) C.C.Q.);

(g)                                 a dispute between the same parties, based on the same facts and having the same object, has not given rise to a decision rendered in the Province of Québec, whether it has acquired the authority of a final judgment (res judicata) or not, or is not pending before a Québec authority, in the first instance, or has been decided

(16) This opinion should be limited to documents where there is submission to a New York court.

in another jurisdiction but the decision does not meet the necessary conditions for recognition in the Province of Québec (Article 3155(4) C.C.Q.);

(h)                                 the outcome of such foreign judgment is not manifestly inconsistent with public order as understood in international relations (Article 3155(5) C.C.Q.) or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada) in respect of certain judgments referred to in these statutes;

(i)                                     such judgment does not directly or indirectly enforce obligations arising from taxation laws of foreign jurisdictions unless in such foreign jurisdictions the obligations resulting from the taxation laws of Québec are recognized and enforced, or arising from other laws of a public nature, such as expropriatory or penal laws (Article 3155(6) and 3162 C.C.Q.); and

(j)                                     the motion to enforce such judgment is commenced in the Province of Québec within applicable limitation periods in the Province of Québec.

(29)                            The distribution of the Securities by the Initial Purchasers to purchasers in each of the provinces of [   ] will be exempt from the prospectus requirements of the applicable Canadian securities laws and no filing, proceeding, approval, consent or authorization is required to be made, taken or obtained under said securities laws to permit the distribution by the Initial Purchasers of the Securities to the purchasers in each such province, other than such filings as are required to be made pursuant to National Instrument 45-106 – Prospectus and Registration Exemptions.

(30)                            The first trade of the Securities in each of the provinces of [   ], other than a trade which is otherwise exempt under applicable Canadian securities laws, will be a distribution but will not be subject to the prospectus requirements of such securities laws, provided that at the date of such trade:

(k)                                    The Issuer is and has been a reporting issuer in a jurisdiction of Canada for the four months immediately preceding the date of such first trade;

(l)                                       at least four months and one day have elapsed from the “distribution date” (as such term is defined in National Instrument 45-102 - Resale of Securities (“NI 45-102”) of the Securities;

(m)                                 the certificates representing the Securities carry the legend, or an ownership statement issued under a direct registration system or other electronic book-entry system acceptable to the regulator bears a legend restriction notation, to the effect provided by Section 2.5(2)3(b) of NI 45-102;

(n)                                   the trade is not a “control distribution” (as such term is defined in NI 45-102);

7

(o)                                 no unusual effort is made to prepare the market or to create a demand for the Securities that are the subject of the trade;

(p)                                 no extraordinary commission or consideration is paid to a person or company in respect of the trade;

(q)                                 if the selling security holder is an “insider” or “officer” of the Issuer (as such terms are defined under the applicable securities laws), the selling security holder has no reasonable grounds to believe that the Issuer is in default of “securities legislation” (as such term is defined in National Instrument 14-101 (“NI 14-101”)); and

(r)                                    in the case of the first trades subject to the securities laws of the Province of Manitoba, the trade is not a “control distribution” as such term is defined in NI 45-102 and is not a transaction involving a purchase or sale or a repurchase or resale that is incidental to a “primary distribution to the public” as defined under the securities laws of the Province of Manitoba.

In rendering such opinion, such counsel may rely as to matters of fact on certificates of responsible officers of Novamerican and public officials that are furnished to the Initial Purchasers. Such opinion shall include customary qualifications, limitations and assumptions.(17)

The opinion of Davies ▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP described above shall be rendered to the Initial Purchasers at the request of Novamerican and shall so state therein.

ANNEX D-3

[Form of Opinion of ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ & Fish, LLP](18)

1.                                       American Steel and Aluminum Corporation, a Massachusetts corporation (“MA Guarantor”) is validly existing as a corporation under Massachusetts law and in good standing with the Secretary of The Commonwealth of Massachusetts, is authorized to transact business as a foreign corporation in the states listed on Schedule 3. MA Guarantor has the corporate power (i) to own its properties and conduct its business as described in the Preliminary Offering Memorandum and the Offering Memorandum and (ii) to execute and deliver the Transaction Documents in which it is named as a party and to perform its obligations thereunder.

2.                                       MA Guarantor has duly authorized, executed, and delivered the Transaction Documents in which it is named as a party, and such Transaction Documents constitute its valid and binding agreements enforceable against it in accordance with their terms.

3.                                       The execution and delivery by each of the MA Guarantor of the Transaction Documents to which it is a party does not and the performance by it of its obligations thereunder will not (i) violate Massachusetts law or federal law, (ii) to our knowledge violate any court order, judgment, or decree applicable to the MA Guarantor, or (iii) violate its charter or by-laws.

4.                                       All the outstanding shares of capital stock or other equity interests of the MA Guarantor have been duly and validly authorized and issued, are fully paid and are non-assessable.

5.                                       No consent, approval, license, or exemption by, or order or authorization of, or filing, recording, or registration with, any governmental authority is required to be obtained by the MA Guarantor in connection with the execution and delivery of the Transaction Documents to which it is a party or the performance by it of its obligations thereunder, except as provided in paragraphs 6 and 7 hereof.

6.                                       The provisions of the Collateral Agreement are effective under the Uniform Commercial Code as in effect in The Commonwealth of Massachusetts (the “UCC”) to create a valid security interest in the Collateral Agent’s favor in so much of the Collateral (as defined in the Collateral Agreement) as constitutes personal property to which Article 9 of the UCC is applicable. Under the UCC, while a debtor is located in a jurisdiction, the local law of that jurisdiction governs the perfection of a non-possessory security interest by the filing of a financing statement. The MA Guarantor is located, for purposes of the UCC, in Massachusetts. The UCC-1 financing statements attached hereto as Exhibit B are in appropriate form for filing with the Massachusetts Secretary of the Commonwealth. Accordingly, upon the due filing of the UCC-1 financing statements attached hereto as Exhibit B with the Massachusetts Secretary of the Commonwealth, in accordance with Section 9-516 of the UCC, the Collateral Agent will have a perfected security interest in such portion of the Collateral in which the perfection of a security interest can be effected by the filing of a financing statement under the UCC.

(18) Capitalized terms used but not defined herein have the meanings ascribed to such terms in the Purchase Agreement (the “Purchase Agreement”) to which this Annex D-3 is attached.

7.                                       The MA Mortgages when (A) duly executed by the president and treasurer (B) notarized and (C) delivered with the appropriate legal descriptions attached, will:

(a)               be in proper form for recording with the appropriate Registry of Deeds listed on Schedule 1 for the county in which the Mortgaged Property is located, provided that the MA Mortgages must be recorded with a certificate of legal existence and good standing of the MA Guarantor issued by the Secretary of the Commonwealth of Massachusetts; and

(b)              when recorded in the Registry of Deeds listed on Schedule 1 next to the name of the Mortgaged Property, create in favor of the Collateral Agent a legal, valid and binding lien on the real property and fixtures described in each MA Mortgage, enforceable as such against the MA Guarantor.

8.                                       No taxes or other charges, including, without limitation, intangible or documentary stamp taxes, mortgage or recording taxes, transfer taxes or similar charges, are payable to Massachusetts or to any jurisdiction therein on account of the execution or delivery or recording or filing of the MA Mortgages or any of the other Transaction Documents or the creation of the indebtedness evidenced or secured by any of the Transaction Documents, as applicable, except for nominal filing or recording fees.

9.                                       The recording of the MA Mortgages with the registries of deeds described on Schedule 1 are the only actions, recordings or filings necessary to publish notice and protect the validity of and to establish of record the rights of the parties under the MA Mortgages.

10.                                 Upon the assumption that all of the applicable provisions of Massachusetts law relating to the preservation of the right to seek a deficiency after the foreclosures of real property have been complied with by the Collateral Agent, the transfer of all or any portion of the Mortgaged Property in connection with the exercise of any remedy under the MA Mortgages, including, without limitation, by way of judicial foreclosure, will not restrict, affect or impair the liability of the MA Guarantor with respect to the indebtedness secured thereby or the Collateral Agent’s rights or remedies relating thereto, including the foreclosure or enforcement of any other security interest or liens securing such indebtedness, and the laws of Massachusetts do not require a lienholder to elect to pursue its remedies either against mortgaged real property or personal property where such lienholder holds security interests and liens on both real and personal property of a debtor.

11.                                 The courts of Massachusetts will enforce those provisions in the Transaction Documents which provide that the validity, construction and enforceability of the Transaction Documents will be governed by the laws of New York, provided, however, that the courts of Massachusetts may apply the internal law of Massachusetts to determine the perfection and the effect of perfection or nonperfection of the liens created under such documents and the application of remedies in enforcing such liens with respect to property located in Massachusetts.

12.                                 Under the Massachusetts criminal usury statute, M.G.L. Chapter 271, Section 49 of the General Laws of the Commonwealth of Massachusetts (the “Massachusetts Usury Statute”), “any lender subject to control, regulation or examination by any state or federal regulatory

2

agency” is exempt from the provisions thereof. With your permission, we have assumed that each of the Initial Purchasers is subject to state and/or federal control, regulation or examination within the meaning of the Massachusetts Usury Statute. Based on such assumption, the Transaction Documents executed by the MA Guarantor will not violate the Massachusetts Usury Statute. If all or any portion of the Securities were transferred to or otherwise held by an entity that is not a “lender subject to control, regulation or examination by any state or federal regulatory agency,” we note that subsection (d) of the Massachusetts Usury Statute provides, in relevant part, that, subject to compliance with the further conditions thereof, the provisions of the Massachusetts Usury Statute “shall not apply to any person who notifies the attorney general of his intent to engage in a transaction or transactions which . . . would be proscribed [by the Massachusetts Usury Statute] . . . providing [sic] any such person maintains records of any such transaction.” Accordingly, assuming the application of currently existing statutory, regulatory, and decisional law in the Commonwealth of Massachusetts with respect to usury, any subsequent holder of all or any of the Securities that is not a lender subject to state or federal regulation would not be subject to the usury prohibition contained in Massachusetts Usury Statute, provided such holder (i) files the requisite notice with the Massachusetts Attorney General, (ii) does not publicly advertise the fact of such notification nor use the fact of such notification to solicit business (except that such notification may be revealed to an individual upon his inquiry), (iii) maintains records of the applicable transaction(s) described in the notice, which records must contain the name and address of the applicable borrower(s), the amount borrowed, the interest and expenses to be paid by the applicable borrower(s), the date that each loan is made and the date or dates on which any payment is due, (iv) makes such records available to the Attorney General of Massachusetts for the purposes of inspection upon any request received from the Attorney General, (v) notifies the Attorney General if such holder’s name and/or address changes and (vi) renews such notification prior to the second anniversary of the filing thereof.

13.                                 Entering into the Transaction Documents with the MA Guarantor will not in and of itself cause the Collateral Agent or any Initial Purchaser to be found to be transacting business (requiring that they register under Massachusetts corporate law as a foreign corporation) or doing banking business in Massachusetts.

This Joinder Agreement (this “Agreement”) is the Joinder Agreement referred to in Section 6(n) of the Purchase Agreement.

Each of the Issuer, Novamerican Steel and the Guarantors agree that this Agreement is being executed and delivered in connection with the issue and sale of the Securities pursuant to the Purchase Agreement and to induce the Initial Purchasers to purchase the Securities thereunder. This Agreement is being executed on the Closing Date, concurrently with the consummation of the sale of Securities pursuant to the Purchase Agreement and the consummation of the other Transactions.

1.                                       Joinder. Each of Novamerican Steel and the Guarantors listed on Schedule 1 hereto hereby agrees to be become bound by the terms, conditions and other provisions of the Purchase Agreement as Novamerican Steel or a Guarantor, as applicable, with all attendant rights, duties and obligations stated therein, with the same force and effect as if originally named therein as a party and as if such party executed the Purchase Agreement on the date thereof.

2.                                       Representations, Warranties and Agreements of the Issuer, Novamerican Steel and the Guarantors. The Issuer, Novamerican Steel and the Guarantors, jointly and severally, represent and warrant to, and agree with, each Initial Purchaser on and as of the date hereof that:

(a)                                  Each of the Issuer, Novamerican Steel and the Guarantors has the corporate or other organizational power to execute and deliver this Agreement and all corporate or other organizational action required to be taken by each of them for the due and proper authorization, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby has been duly and validly taken; this Agreement has been duly authorized, executed and delivered by each of the Issuer, Novamerican Steel and the Guarantors and constitutes a valid and legally binding agreement of each of the Issuer, Novamerican Steel and the Guarantors, enforceable against each of the Issuer, Novamerican Steel and the Guarantors in accordance with its terms, subject to the Enforceability Exceptions;

(b)                                 the representations, warranties and agreements set forth in Section 3 of the Purchase Agreement are true and correct on and as of the date hereof; and

(c)                                  Nothing has come to the attention of the Issuer or any of the Guarantors that has caused the Issuer or any of the Guarantors to believe that the statistical and market-related data included in each of the Time of Sale Information and the Offering Memorandum is not based on or derived from sources that are reliable and accurate in all material respects.

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

4.                                       Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (the “Related Proceedings”) may be instituted in the federal courts of the United States located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (each such judgment, a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints CT Corporation System as its agent to receive service of process or other legal summons for purposes of any Related Proceeding that may be instituted in any Specified Court.

5.                                       Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts and, with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

6.                                       Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers could purchase U.S. dollars with such other currency in New York City on the business day preceding that on which final judgment is given. The obligations of the Issuer, Novamerican Steel and each Guarantor in respect of any sum due from them to any Initial Purchaser shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by such Initial Purchaser of any sum adjudged to be so due in such other currency, on which (and only to the extent that) such Initial Purchaser may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to such Initial Purchaser hereunder, the Issuer, Novamerican Steel and each Guarantor agree, as a separate obligation and notwithstanding any such judgment, to indemnify such Initial Purchaser against such loss. If the U.S. dollars so purchased are greater than the sum originally due to such Initial Purchaser hereunder, such Initial Purchaser agrees to pay to the Issuer, Novamerican Steel and the Guarantors (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Initial Purchaser hereunder.

7.                                       Counterparts. This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

8.                                       Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

9.                                       Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.
