3.2 Purchase Entirely for Own Account. This Agreement is made with such Investor in reliance upon such Investor’s representation to the Company, which by such Investor’s execution of this Agreement such Investor hereby confirms, that the Shares to be received by such Investor and the Conversion Shares (collectively, the “Securities”) will be acquired for investment for such Investor’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof, and that such Investor has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, such Investor further represents that such 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 Securities.

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 the Investors to rely thereon.

3.4 Investment Experience. Such Investor is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can 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.

In this connection, such Investor represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act.

3.8 Legends. It is understood that the certificates evidencing the Securities 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.”

directors, in making its investment or decision to invest in the Company.

The warranties, representations and covenants of the Company and Investors contained in or made pursuant to this Agreement shall survive the execution and delivery of this Agreement and the Closing and shall in no way be affected by any investigation of the subject matter thereof made by or on behalf of the Investors or the Company; provided, however, that the warranties, representations and covenants of the Company set forth in Section 2.31 shall only survive until the earlier of (a) the three (3) year anniversary of the execution and delivery of this Agreement and (b) immediately prior to the initial closing of the next round of equity financing of the Company following the issuance of the shares of Series A-1 contemplated by this Agreement with gross cash proceeds to the Company of at least $5,000,000 at a per share price not less than the Series A-1 Purchase Price (such number as adjusted for any stock splits, combinations or the like).

6.2 Indemnification; Put Right.

(a) Indemnification by the Company. Subject to the limitations set forth in Section 6.1 and this Section 6.2, in consideration of each Investor’s execution and delivery of this Agreement and acquiring the Securities hereunder, the Company shall defend, protect, indemnify and hold harmless each Investor and each permitted transferee of the Securities and all of their partners, members, officers, directors and employees and any of the foregoing persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (collectively, “Claims”), incurred by any Indemnitee as a result of, or arising out of, or relating to any misrepresentation or breach of any representation or warranty made by the Company in Section 2.31 of this Agreement (a “Violation”). To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Claims which is permissible under applicable law.

(b) Procedures for Indemnification. Promptly after an Indemnitee has knowledge of any Claim as to which such Indemnitee reasonably believes indemnity may be sought or promptly after such Indemnitee receives notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnitee shall, if a Claim in respect thereof is to be made against any the Company under this Section 6.2, deliver to the Company a written notice of such Claim, and

the Company shall have the right to participate in, and, to the extent the Company so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Company and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel if, in the reasonable opinion of counsel retained by the Company, the representation by such counsel of the Indemnitee and the Company would be inappropriate due to actual or potential differing interests between such Indemnitee and the Company; provided, further, that the Company shall not be responsible for the reasonable fees and expense of more than one (1) separate legal counsel for the Indemnitees. In the case of the Indemnitees, the legal counsel referred to in the immediately preceding sentence shall be selected by the Investors holding a majority in interest of the Securities to which the Claim relates. The Indemnitees shall cooperate fully with the Company in connection with any negotiation or defense of any such action or Claim by the Company and shall furnish to the Company all information reasonably available to the Indemnitees which relates to such action or Claim. The Company shall keep the Indemnitees fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. The Company shall not be liable for any settlement of any Claim effected without its prior written consent; provided, however, that the Company shall not unreasonably withhold, delay or condition its consent. The Company shall not, without the prior written consent of the Indemnitees, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a full release from all liability in respect to such Claim and action and proceeding. After indemnification as provided for under this Agreement, the rights of the Company shall be subrogated to all rights of the Indemnitees with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the Company as provided in this Agreement shall not relieve the Company of any liability to the Indemnitees under this Section 6.2, except to the extent that the Company is materially prejudiced in its ability to defend such action.

(c) Put Right. Subject to applicable law, in the event of any final, non-appealable adjudication that a Violation has occurred, each Investor shall have the right to sell to the Company the Securities equal to the number of shares each Investor originally purchased from the Company pursuant to this Agreement. Such sale shall be made on the following terms and conditions:

(i) The price per share at which the shares are to be sold to the Company shall be equal to the price per share paid by the Investor to the Company (such number as adjusted for any stock splits, combinations or the like).

(ii) The Company shall, upon receipt of the certificate or certificates for the shares to be sold by an Investor pursuant to this Section 6.2, pay the aggregate purchase price therefor, in cash or by other means acceptable to the Investor.

(d) Survival of and Limitation of Obligations. The obligations of the Company under this Section 6.2 shall survive the transfer of the Securities by the Indemnitees; provided, that such transfer is made to an existing investor in the Investor or an affiliated entity of the Investor. In addition, in no event shall the obligations of the Company to indemnify an Investor or permitted transferee exceed the aggregate amount of such Investor’s initial investment in the Company under this Agreement.

6.3 Successors and Assigns. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties (including transferees of any Securities).

Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.
