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. The Company is in the process of reviewing its compliance with this guidance and has filed paperwork with the EPA. Accordingly, the Company withholds any representation or warranty regarding the matters disclosed in this
Section 2.15(b), including its compliance with the new EPA guidance.

with all the information that Investor has requested in writing for deciding whether to purchase the Shares. Neither this Agreement (including all the exhibits and schedules hereto) nor any other statements or certificates made or delivered in
connection herewith contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements herein or therein not misleading in light of the circumstances under which they were made. 
 2.18 Registration Rights. Except as provided in the Investors’ Rights Agreement, the Company has not granted or agreed to grant any
registration rights, including piggyback rights, to any person or entity.

liens, encumbrances and security interests that arise in the ordinary course of business and/or pursuant to applicable law, and minor defects in title, none of which, individually or in the aggregate, would reasonably be expected to have a Material
Adverse Effect. 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.

labor union has requested or, to the Company’s knowledge, has sought to represent any of the employees, representatives or agents of the Company. There is no strike or other labor dispute involving the Company pending, or to the Company’s
knowledge, threatened in writing, that would reasonably be expected to have a Material Adverse Effect, nor is the Company aware of any labor organization activity involving its employees. The Company is not aware that any officer or key employee, or
that any group of key employees, intends to terminate their employment with the Company, nor does the Company have a present intention to terminate the employment of any of the foregoing. The employment of each officer and employee of the Company is

processes (collectively, “Intellectual Property”) it needs to operate its business as currently conducted, other than Intellectual Property that it reasonable believes is invalid or it can obtain rights to through a license or
cross-licensing arrangement. The Company has not received any communications alleging that the Company has violated or, by conducting its business as presently proposed, would violate any of the Intellectual Property of any other person or entity.
The Company is not aware that any of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency,
that would interfere with the use of his or her best efforts to promote the interests of the Company or that would conflict with the Company’s business as presently proposed to be conducted. Neither the execution nor delivery of this Agreement
or the Investors’ Rights Agreement, nor the carrying on of the Company’s business by the employees of the Company, nor the conduct of the Company’s business as presently proposed, will, to the Company’s knowledge, conflict with
or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under which any of such employees is now obligated. The Company does not believe it is or will be necessary to
utilize any inventions of any of its employees (or people it currently intends to hire) made prior to their employment by the Company.

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.

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

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

 3.5 Accredited Investor. Investor is an “accredited investor” within the meaning of SEC
Rule 501 of Regulation D and has reviewed Schedule 3.5 before making this representation to the Company. 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. 
 (c) Any legend required by applicable laws. 
 4. Optional Conversion of the Shares. 
 4.1
Optional Conversion. Each 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 $7,000,000 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 
  

 9 








 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 1.00 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 November 2008, this number shall be
