WHEREAS, the Company wishes to sell up to an aggregate of 1,111,111 shares of the Company’s Series C-1 Preferred Stock (“Shares”) to the Investor, at a purchase price of $1.80 per Share, and the Investor wishes to purchase Shares from the Company.

NOW, THEREFORE, in consideration of the mutual covenants, agreements and conditions, and upon acknowledgement of each of the parties of the receipt of valuable consideration, the parties herein agree as follows:

1. Purchase and Sale of Shares.

1.1 The Closing. At the Closing (as defined below), the Company shall issue and sell to Investor such number of Shares as is set forth immediately below Investor’s name on the signature pages hereto against delivery to the Company by Investor of an amount equal to $1.80 times the number of Shares to be purchased by the Investor (the “Purchase Price”), paid by (a) cash (by check or wire transfer) in United States Dollars to the Company to be held in escrow until the Closing, for release to the Company thereafter or (b) cancellation of indebtedness of the Company to Investor. Promptly after the Closing, the Company shall deliver to Investor a duly executed certificate representing the Shares which Investor is purchasing hereunder. The purchase and sale transaction contemplated hereby will close on the first business day immediately following the satisfaction of the Closing conditions set forth herein, which is targeted to be no later than 5:00 p.m., Pacific Time on Tuesday, February [20], 2009, as such date and time may be modified by the Company in its sole discretion (such day, the “Closing”).

1.2 Additional Closing(s).

(a) Conditions of Additional Closing(s). At any time and from time to time following the Closing, the Company may, at one or more additional closings (each an “Additional Closing”), without obtaining the signature, consent or permission of Investor, offer and sell to other investors (the “New Investors”), at a price of $1.80 per Share, up to that number of Shares that is equal to 1,111,111 Shares less the number of Shares previously issued and sold by the Company. New Investors may include persons or entities who are already owners of shares of the Company’s Series C-1 Preferred Stock or other capital stock.

(b) Amendments. The Company and the New Investors purchasing Shares at each Additional Closing will execute a Subscription Agreement in substantially the same form hereof, and the New Investors will, to the extent not already a party thereto, execute counterpart signature pages to: (i) the Amended and Restated Investors’ Rights Agreement in the form attached to this Agreement as Exhibit A, as amended (the “Investors’ Rights Agreement”), (ii) the Amended and Restated Right of First Refusal and Co-Sale Agreement in the form attached to this Agreement as Exhibit B, as amended (the “ROFR Agreement”), and (iii) the Amended and Restated Voting Agreement in the form attached to this Agreement as Exhibit C, as amended (the “Voting Agreement”) (the Investors’ Rights Agreement, ROFR Agreement and Voting Agreement, as such agreements may be amended, collectively, the “Related Agreements”).

The Company is not in violation of any provision of its Restated Certificate or Bylaws nor, to its knowledge, of any instrument, judgment, order, writ, decree or contract, statute, rule or regulation to which the Company is subject and a violation of which would reasonably be expected to have a Material Adverse Effect. The execution, delivery and performance of this Agreement and the Related Agreements, and the consummation of the transactions contemplated hereby and thereby will not result in any such violation, or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision or an event that results in the creation of any lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets or properties.

The Company is not a guarantor or indemnitor of any indebtedness of any other person, firm or corporation.

2.13 Permits. The Company has all franchises, permits, licenses and any similar authority necessary for the conduct of its business as now being conducted by it, except to the extent the lack of which would not reasonably be expected to have a Material Adversely Effect. The Company is not in default under any of such franchises, permits, licenses or other similar authority which would be reasonably expected to have a Material Adverse Effect.

(a) Except as set forth in Section 2.14(b), to its knowledge, the Company is not in violation of any applicable statute, law or regulation relating to the environment or occupational health and safety, and, to its knowledge, no material expenditures are or will be required in order to comply with any such existing statute, law or regulation.

(b) The US Environmental Protection Agency (the “EPA”) has issued recent guidance regarding the classification of carbon nanotubes under the Toxic Substances Control Act. The EPA has stated that it now considers carbon nanotubes to be “new chemicals” rather than materials previously listed on the TSCA Inventory, such as synthetic graphite or other carbon compounds.

Accordingly, the Company withholds any representation or warranty regarding the matters disclosed in this Section 2.14(b), including its compliance with the new EPA guidance.

With respect to the property and assets it leases, the Company is in compliance with such leases and, to its knowledge, holds a valid leasehold interest free of any liens, claims or encumbrances, subject to clauses (i)-(ii) of the foregoing sentence, except to the extent the failure to be in compliance or hold a valid leasehold interest would not reasonably be expected to have a Material Adverse Effect.

3. Representations and Warranties of Investor. Investor hereby represents, warrants and covenants to the Company that:

3.1 Authorization. Investor has full power and authority to enter into this Agreement and the Related Agreements to which it is a party, and each such agreement constitutes its valid and legally binding obligation, enforceable in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, and (iii) to the extent the indemnification provisions contained in the Related Agreements may be limited by applicable federal or state securities laws.

3.2 Purchase Entirely for Own Account. This Agreement is made with Investor in reliance upon Investor’s representation to the Company, which by Investor’s execution of this Agreement, Investor hereby confirms that the Shares will be acquired for investment for Investor’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that Investor has no present intention of selling, granting any participation in or otherwise distributing the same. By executing this Agreement, Investor further represents that Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Shares.

3.3 Disclosure of Information. Investor believes it has received all the information it considers necessary or appropriate for deciding whether to purchase the Shares. Investor further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of Investor to rely thereon.

3.4 Investment Experience. Investor is an investor in securities of companies in the development stage and acknowledges that he/she/it is able to bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Shares. If other than an individual, Investor also represents it has not been organized for the purpose of acquiring the Shares.

3.5 Accredited Investor. Investor is an “accredited investor” within the meaning of SEC Rule 501 of Regulation D. All of the information in the Investor Questionnaire delivered by Investor to the Company in connection with Investor’s purchase of the Shares remains complete, true and correct as of the Closing or the Additional Closing, as applicable.

3.6 Restricted Securities. Investor understands that the Shares it is purchasing are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering, and that under such laws and applicable regulations, such Shares may be resold without registration under the Act only in certain limited circumstances. In the absence of an effective registration statement covering the Shares or an available exemption from registration under the Act, the Shares (and any Common Stock issued on conversion of the Shares) must be held indefinitely.

3.7 No Brokers. Investor has not taken any action which would give rise to any claim by any person for brokerage commissions, finder’s fees or similar payments relating to this Agreement or the transactions contemplated hereby.

3.8 Legends. It is understood that the certificates evidencing the Shares may bear one or all of the following legends:

(a) “These securities have not been registered under the Securities Act of 1933, as amended. They may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or an opinion of counsel satisfactory to the Company that such registration is not required or unless sold pursuant to Rule 144 of such Act.”

(b) Legends required to indicate that the Shares are subject to the terms of the Investors Rights Agreement and ROFR Agreement.

4. Optional Conversion of the Shares.

4.1 Optional Conversion. Investor shall have the right, by giving notice thereof to the Company pursuant to this Section 4, to convert all (but not less than all) of the outstanding Shares held by the Investor (and purchased under this Agreement) into shares of the Company’s Qualified Stock (as defined below), pursuant to the provisions of this Section 4 concurrently with the closing of a Qualified Transaction (as defined below)(or the first closing in a series of closings).

4.2 Qualified Transaction. A “Qualified Transaction” shall mean the Company’s receipt of at least $500,000 in proceeds from: (i) a sale by the Company, in one or more related transactions, of a new series of preferred stock (the “Qualified Stock”) in a financing event (the “Qualified Financing”); or (ii) a combination of (a) a sale of Qualified Stock as described in Section 4.2(i), and (b) the sale by the Company of some or all of its assets and/or business operations in materials for anti-static polymers.

4.3 Notice. The Company shall provide the Investor with a notice no later than 15 business days prior to the closing of the Qualified Transaction indicating the proposed closing date, together with the terms and conditions of the Qualified Transactions, the rights, preferences and privileges of the Qualified Stock and the conversion calculation determined in accordance with Section 4.4 below. Each Investor shall have the right to exercise its rights to convert its Shares into the Qualified Stock under Section 4.1 by giving notice thereof to the Company no later than 5 business days prior to the proposed closing date.

4.4 Conversion Calculation. In connection with a Qualified Transaction, the Shares shall be converted into Qualified Stock in accordance with the following formula:

A = B * [(C ÷ D) * E]

A = the number of shares of Qualified Stock issuable to Investor in connection with the Qualified Transaction;

B = the number of Shares purchased by Investor pursuant to this Agreement;

C = $1.80;

D = the price per share at which the Qualified Stock is sold to investors in the Qualified Financing; and

E = a variable number between 1.06 and 1.10, which will adjust depending on the month that the closing of the Qualified Financing occurs (or the month that the first closing in a series of related closings occurs). If the closing of the Qualified Financing occurs in February 2009, this number shall be 1.06; if the closing of the Qualified Financing occurs in March 2009, this number shall be 1.08; if the closing of the Qualified Financing occurs in April 2009, or at any time after April 2009, this number shall be 1.10. In no event shall this number exceed 1.10.

For the avoidance of doubt, the calculation in this Section 4.3 shall be performed in the following order: (i) divide C by D, (ii) multiply the amount in (i) by E, and (iii) multiply the amount in (ii) by B.

4.5 Deliverables. Upon any conversion of Shares under this Section 4, the Investor will execute and deliver to the Company, at the closing of such Qualified Financing, such stock purchase agreement, investors’ rights agreement, co-sale agreement, voting and/or other agreements as are entered into by the investors in the Qualified Financing generally. The Company shall not be obligated to issue certificates evidencing the shares of Qualified Stock issuable upon conversion unless the certificates evidencing the Shares are either delivered to the Company or its transfer agent, or the Investor notifies the Company or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such certificates. Upon the occurrence of such conversion of the Shares, the Investor shall surrender the certificates representing such Shares at the office of the Company or any transfer agent for the Company’s capital stock. Thereupon, there shall be issued and delivered to the Investor promptly at such office and in its name as shown on such surrendered certificate or certificates, a certificate or certificates for the number of shares of Qualified Stock into which the Shares surrendered were convertible on the date on which such automatic conversion occurred.

5. Conditions to Investor’s Obligations at Closing. The following conditions must be satisfied by the Company, unless waived by Investor, in Investor’s sole and absolute discretion.
