(C)              Compliance With Securities Laws.

(i)                The Holder of this Warrant, or if the Holder is a custodian, the beneficial owner of this Warrant, by acceptance hereof, acknowledges that this Warrant and the shares of Common Stock to be issued upon exercise hereof are being acquired solely for the Holder’s (or beneficial owner’s) own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances that will not result in a violation of any federal or state securities laws. Upon exercise of this Warrant (other than pursuant to the net exercise provision of Section 3(C)), the Holder shall as a condition to such exercise, if reasonably requested by the Company, confirm in writing, in a form reasonably satisfactory to the Company, that the shares of Common Stock so purchased are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale.

During the term of this Warrant, the Company will at all times have authorized and reserved for the purpose of issuance upon exercise of this Warrant, a sufficient number of shares of the Company’s Common Stock to provide for the exercise of this Warrant. If at any time during the term of this Warrant the number of authorized but unissued shares of Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes. All shares that may be issued upon the exercise of rights represented by this Warrant upon issuance, will be fully paid and non-assessable, free from all taxes, liens and charges in respect of the issuance thereof.

9.                 Amendments. This Warrant may not be amended, nor may any provision of this Warrant or any default, misrepresentation, or breach under this Warrant be waived or amended, except in a writing executed by all parties to this Warrant.

10.               Special Provision.

(A)          Reclassification. If the Company at any time while this Warrant, or any portion thereof, remains outstanding and unexpired, by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as a result of such change with respect to the securities that were subject to the purchase rights under this Warrant immediately prior to such reclassification or other change and the Exercise Price therefore shall be appropriately adjusted, all subject to further adjustment as provided in this Section 10.

(B)              Split, Subdivision, Reverse Split or Combination of Shares. If the Company at any time while this Warrant, or any portion thereof, remains outstanding and unexpired shall issue additional shares of its Common Stock as a dividend with respect to any shares of its Common Stock, or split, subdivide, reverse split or combine the securities as to which purchase rights under this Warrant exist, into a different number of securities of the same class, the Exercise Price per share for such securities shall be proportionately decreased in the case of a stock dividend, split or subdivision or proportionately increased in the case of a combination or reverse split and the number of shares which the Holder hereof shall be entitled to receive upon exercise shall be correspondingly appropriately adjusted.

11.               No Impairment. The Company will not avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith use its best efforts to carry out all of the provisions of this Warrant, including without limitation, the provisions of Section 10, and to take all such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment.

12.               Lockup Following Public Offering. The Holder agrees not to offer, sell or otherwise dispose of any of the shares of Common Stock within 180 days following the effective date of an initial public offering of Common Stock by the Company or such shorter time period as approved by the Company in writing or such longer period up to 12 months as may be required by the managing underwriter or otherwise for listing of the Company’s Common Stock.

13.                Miscellaneous.
