The Board of Directors of
Altair Nanotechnologies Inc.
1725 Sheridan Avenue, Suite 140
Cody, Wyoming 82414

Dear Sirs/Mesdames:

Re: Registration Statement on Form S-3

We have acted as Canadian counsel to Altair Nanotechnologies Inc., a corporation incorporated under the Canada Business Corporations Act (the "Corporation"), in connection with the preparation of the Corporation's Registration Statement on Form S-3, File No. 333-117125, (the "Registration Statement") for the registration under the Securities Act of 1933, as amended, of up to 3,600,000 common shares (the "Common Shares") of the Corporation for sale from time to time by the selling shareholders identified in the Registration Statement. In connection with the opinions hereinafter expressed, we have conducted or caused to be conducted such searches as we have considered necessary, advisable or relevant. We have also prepared or examined all such documents, corporate records of the Corporation, certificates of officers of the Corporation, and other materials as we considered advisable or relevant. We have also examined such statutes, corporate and public records and other documents including certificates or statements of public officials, and considered such matters of law, as we have deemed necessary as a basis for the opinions hereinafter expressed. For the purposes of the opinions set forth below, we have assumed, with respect to all documents examined by us, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to authentic or original documents of all documents submitted to us as certified, conformed, telecopied or photostatic copies and the legal capacity at all relevant times of any natural person signing any such document.

We are solicitors qualified to carry on the practice of law in the Province of Ontario only. We express no opinion as to any laws, or matters governed by any laws, other than the laws of the Province of Ontario and the federal laws of Canada applicable to the Corporation as such laws exist on the date hereof.

Based upon and subject to the foregoing, we are of the opinion that:

1. the 1,875,000 Common Shares described in the Registration Statement as being issued and outstanding have been legally issued as fully paid and non-assessable shares; and

2. assuming such Common Shares are issued in compliance with the terms and conditions of the governing warrants, including receipt of the exercise price specified in the governing warrants, 1,750,000 Common Shares described in the Registration Statement as being issuable upon the exercise of warrants to purchase common shares, will, when issued, be legally issued as fully paid and non-assessable shares.

1

We hereby consent to the reference to our firm under "Legal Matters" in the prospectus which constitutes a part of the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement.

Yours very truly,

/s/ Goodman and Carr LLP

9.1.10. Schnur and Toyota acknowledge that their aforesaid representations are a material inducement to every other party to enter into this Agreement.

9.1.11. Investment Representations.

a. Purchase for Own Account. Toyota is the sole and true party in interest, is acquiring the Settlement Shares for its own account for investment, is not purchasing the Settlement Shares for the benefit of any other person, and has no present intention of holding or managing the Settlement Shares with others or of selling, distributing or otherwise disposing of any portion of the Settlement Shares. Toyota has its principal place of business in the state of Illinois.

b. Disclosure and Review of Information. Toyota acknowledges and represents that it has received and reviewed copies of Altair's Annual Report on Form 10-K for the year ended December 31, 2003 and Altair Quarterly Report on Form 10-Q for the quarter ended March 31, 2004 (the "SEC Filings"). In addition, Toyota acknowledges and represents that Toyota has been given a reasonable opportunity to review all documents, books and records of Altair pertaining to this investment, and has been supplied with all additional information concerning Altair and the Settlement Shares that has been requested by Toyota, has had a reasonable opportunity to ask questions of and receive answers from Altair or its representatives concerning this investment, and that all such questions have been answered to the full satisfaction of Toyota. Toyota has received, and acknowledges that it is receiving, no representations, written or oral, from Altair or its officers, directors, employees, attorneys or agents other than those contained in this Agreement and the SEC Filings. In making its decision

5

to purchase the Securities, Toyota has relied solely upon its review of the SEC Filings, this Agreement, and independent investigations made by it or its representatives without assistance of Altair.

c. Speculative Investment. Toyota understands that (i) it must bear the economic risk of the investment in the Settlement Shares for an indefinite period of time because the Settlement Shares have not been registered under the Securities Act of 1933, as amended (the "Securities Act") or qualified under the Securities Act or the securities laws of any other jurisdiction and (ii) its investment in Altair represented by the Settlement Shares is highly speculative in nature and is subject to a high degree of risk of loss in whole or in part. Toyota has adequate means of providing for its current needs and possible contingencies, and is able to bear the high degree of economic risk of this investment, including, but not limited to, the possibility of the complete loss of Toyota's entire investment and the limited transferability of the Settlement Shares, which may make the liquidation of this investment impossible for the indefinite future.

d. Accredited Schnur Parties Status. Toyota is an "accredited investor" within the meaning of Rule 501(a) promulgated under the Securities Act in that, among other reasons, all equity owners of Toyota had individual income (exclusive of any income attributable to my spouse) in excess of $200,000 in each of the most recent two years and reasonably expect to have an individual income in excess of $200,000 for the current year and/or) alimony paid, and have an individual net worth, or my spouse and I have a combined individual net worth, in excess of $1,000,000.

e. Investment Experience. Toyota has experience as an investor in securities and acknowledges that it can bear the economic risk of its investment in the Securities. By reason of Toyota's business or financial experience or the business or financial experience of its professional advisors who are unaffiliated with and who are not compensated by Altair or any affiliate or selling agent of Altair, directly or indirectly, Toyota has the capacity to protect its own interests in connection with its purchase of the Securities. Toyota has not been organized solely for the purpose of acquiring the Securities.

f. Restricted Securities. Toyota understands that the Settlement Shares are and will be "restricted securities" under the Securities Act inasmuch as they are being acquired from Altair in a transaction not involving a public offering, and that, under the Securities Act and applicable regulations thereunder, such securities may be resold without registration under the Securities Act only in certain limited circumstances.

g. Legends. Toyota understands that the certificates evidencing the Settlement Shares will bear the legend set forth below, together with any other legends required by the laws of the Province of Ontario and any other state or province with jurisdiction:

6

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS AND HAVE BEEN TAKEN FOR INVESTMENT PURPOSES ONLY AND NOT WITH A VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION THEREOF. THESE SECURITIES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED UNLESS A REGISTRATION STAEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, IS IN EFFECT WITH RESPECT TO SUCH SECURITIES OR ALTAIR HAS RECEIVED AN OPINION IN FORM AND SUBSTANCE SATISFACTORY TO ALTAIR PROVIDING THAT AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, IS AVAILABLE.

h. The legend set forth above shall be removed by Altair from any certificate evidencing any of the Settlement Shares only (i) upon receipt by Altair of an opinion in form and substance satisfactory to Altair that such legend may be removed pursuant to Rule 144 promulgated under the Securities Act, or (ii) upon confirmation that a registration statement under the Securities Act is at that time in effect with respect to the legended Settlement Share and that such transfer will not jeopardize the exemption or exemptions from registration pursuant to which the respective Settlement Shares was issued.

9.2. Altair hereby covenants, represents, and warrants to the other parties to this Agreement as follows:

9.2.1. Altair is correctly described and named in this Agreement;

9.2.2. Before executing this Agreement, Altair became fully informed of the terms, contents, provisions, and effect of this Agreement and the attached exhibits;

If the Registration Statement is not filed with the SEC on or prior to the Filing Deadline, the Company will make payments to each Investor (pro rata based upon the number of Registrable Securities), as liquidated damages and not as a penalty, 525 shares per day for each day following the date by which the Registration Statement should have been filed for which no Registration Statement is filed.

The Company shall notify the Investors by facsimile or email as promptly as practicable after any Registration Statement is declared effective and shall simultaneously provide the Investors with copies of any related Prospectus. If (A) a Registration Statement covering the Registrable Securities is not declared effective by the SEC within 120 days after the Filing Deadline (the "Effectiveness Deadline") then the Company shall make to each Investor (pro rata based upon the number of Registrable Securities held by such Investor), as liquidated damages and not as a penalty, 525 shares per day for each day following the date by which such Registration Statement should have been effective. Those payments will be in lieu of any other monetary damages the Investors may seek or obtain as a result of the respective delay; provided, however, nothing in this Agreement will prohibit an Investor from seeking specific performance of the Company's obligations under this Agreement.

(d) Underwritten Offering. If the company elects, in its discretion, to engage an underwriter with respect to any offering pursuant to a Registration Statement, the Company is entitled to select an investment banker and manager to administer the offering, which investment banker or manager will be reasonably satisfactory to the Required Investors.

3. Company Obligations. The Company shall use its best efforts to effect the registration of the Registrable Securities in accordance with the terms hereof, and the Company will, as expeditiously as possible,

(c) (i) provide copies to and permit a single counsel designated by the Investor holding the largest amount of Registrable Securities (which shall be Jenkens & Gilchrist unless the Company is otherwise notified) to review the initial Registration Statement no fewer than four Business Days prior to the filing of the initial Registration Statement with the SEC and (ii) provide to that single counsel copies of all post-effective amendments and supplements to the Registration Statement.

(d) furnish to the Investors and their legal counsel (which may be by email or portable document format (PDF) file) (i) one copy of any Registration Statement and any amendment thereto and each preliminary prospectus

3

and Prospectus and each amendment or supplement thereto and (ii) the reasonably requested number of copies of a Prospectus, including a preliminary prospectus, and all amendments and supplements thereto;

(j) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC under the 1933 Act and the 1934 Act and take other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder; and

(k) with a view to making available to the Investors the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the Investors to sell shares of Common Stock

Except for disclosures to any Investor whose representative or Affiliate occupies a seat or has observation rights with respect to the board of directors of the Company or any of its subsidiaries, the Company shall not disclose material nonpublic information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of the information the Company identifies the information as being material nonpublic information and provides the Investors, the advisors and representatives with the opportunity to accept or refuse to accept that material nonpublic information for review and any Investor wishing to obtain that information enters into an appropriate confidentiality agreement with the Company with respect thereto.

5. Obligations of the Investors.

The scope of any indemnification in favor of an underwriter shall be limited to the same extent as the indemnity provided in Section 6(b) hereof.

6. Indemnification.

(a) Indemnification by the Company. The Company will indemnify and hold harmless each Investor and its officers, directors, members, employees and agents, successors and assigns, and each other person, if any, who controls that Investor within the meaning of the 1933 Act, against any losses, claims, damages or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as those losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, any preliminary prospectus or final

6

prospectus contained therein, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a "Blue Sky Application"); (iii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or
(iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with the registration and will reimburse the Investor, and each officer, director, member, employee or agent and each controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any case if and to the extent that the loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by that Investor or the controlling person in writing specifically for use in the Registration Statement or Prospectus.

(b) Indemnification by the Investors. In connection with any registration pursuant to the terms of this Agreement, each Investor will furnish to the Company in writing the information as the Company reasonably requests concerning the holders of Registrable Securities or the proposed manner of distribution for use in connection with any Registration Statement or Prospectus and agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees and each person who controls the Company (within the meaning of the 1933 Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that the untrue statement or omission is contained in any information furnished by the Investor to the Company specifically for inclusion in the Registration Statement or Prospectus or amendment or supplement thereto.

(c) Conduct of Indemnification Proceedings. Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit the indemnifying party to assume the defense of the claim with counsel reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of the claim, but the fees and expenses of that counsel shall be at the expense of that person unless (a) the indemnifying party has agreed to pay those fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of the claim and employ counsel reasonably satisfactory to that person or (c) in the reasonable judgment of that person, based upon written advice of its counsel, a conflict of interest exists between that person and the indemnifying party with respect to the claims (in which case, if the person notifies the indemnifying party in writing that the person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of the claim on behalf of that person); and provided, further, that

7

the failure of any indemnified party to give notice promptly as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that the failure to give notice promptly shall materially adversely affect the indemnifying party in the defense of the claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all the indemnified parties. No indemnifying party will, except with the consent of the indemnified party, not to be unreasonably withheld, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to the indemnified party of a release from all liability in respect of the claim or litigation.

(d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in that proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any person not guilty of the fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the net proceeds (net of all expenses paid by that holder in connection with any claim relating to this Section 6 and the amount of any damages the holder has otherwise been required to pay by reason of the untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to the contribution obligation (or that could be received by the Investor upon the sale of the Registrable Securities included in the Registration Statement at fair market value on the date of determination of liability to the extent any Registrable Securities remain unsold).

7. Miscellaneous.

(a) Amendments and Waivers. This Agreement may be amended only by a writing signed by the Company and the Required Investors. The Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company shall have obtained the written consent to the amendment, action or omission to act, of the Required Investors.

(b) Notices. All notices and other communications provided for or permitted hereunder shall be in writing, shall specifically refer to this Agreement, and shall be delivered or transmitted by reliable overnight courier or other reliable delivery service, and shall be addressed to the party at the address set forth on the signature page hereof.

(c) Assignments and Transfers by Investors. The provisions of this Agreement shall be binding upon and inure to the benefit of the Investors and their respective successors and assigns. An Investor may transfer or assign, in whole or from time to time in part, to one or more persons its rights hereunder in connection with the transfer of Registrable Securities by that Investor to that person, provided that that Investor complies with all laws applicable thereto, provides written notice of assignment to the Company promptly after the assignment is effected and the assignee executes a counterpart to this Agreement assuming all rights and obligations of an Investor hereunder.

8

(d) Assignments and Transfers by the Company. This Agreement may not be assigned by the Company without the prior written consent of the Required Investors, provided, however, that the Company may assign its rights and delegate its duties hereunder to any surviving or successor corporation in connection with a merger or consolidation of the Company with another corporation, or a sale, transfer or other disposition of all or substantially all of the Company's assets to another corporation, without the prior written consent of the Required Investors, after notice duly given by the Company to each Investor; provided that such successor corporation assumes the Company's obligations hereunder.

(e) Benefits of the Agreement. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties.

(f) Counterparts; Faxes. 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. This Agreement may also be executed via facsimile, which shall be deemed an original.

(g) Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

(h) Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of that prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and the prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable that provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision of law that renders any provisions hereof prohibited or unenforceable in any respect.

(i) Further Assurances. The parties shall execute and deliver all further instruments and documents and take all other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

(j) Entire Agreement.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Nevada without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the state and federal courts of the State of Nevada for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.
