Upon conversion of this Secured Note, the Company shall take all such actions as are necessary in order to ensure that the capital stock issuable with respect to such conversion shall be duly and validly authorized and issued, fully paid and nonassessable.

10.Notices. Except as may be otherwise provided herein, all notices, requests, waivers and other communications made pursuant to this Secured Note shall be made in accordance with Section 5.7 of the Agreement.
11.Severability. If one or more provisions of this Secured Note are held to be unenforceable under applicable law, such provision shall be excluded from this Secured Note and the balance of this Secured Note shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms.
12.Assignment. The Company shall not have the right to assign its rights and obligations hereunder or any interest herein. Neither this Secured Note nor any rights hereunder may be assigned, conveyed or transferred, in whole or in part, without the Company’s prior written consent, which the Company may withhold in its sole discretion; provided, however, that this Secured Note may be assigned, conveyed or transferred without the prior written consent of the Company to any Affiliate of Holder (including, if applicable, an affiliated venture capital fund) who executes and delivers to the Company an acknowledgement that such Affiliate agrees to be subject to, and bound by, all the terms and conditions of this Secured Note and the Agreement and satisfies the Company that such transfer complies with applicable securities laws and that such affiliate as an “accredited investor” within the meaning of Securities and Exchange Commission Rule 501 of Regulation D, as then in effect. Subject to the foregoing, the rights and obligations of the Company and Holder under this Secured Note shall be binding upon and benefit their respective permitted successors, assigns, heirs, administrators and transferees. Notwithstanding anything to the foregoing, this Secured Note may not be sold or transferred to a “United States Person” as defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended, and shall not be enforceable by any United States Person. Any transfer of this Secured Note may be effected only by surrender of the original of the executed Secured Note by the registered holder thereof, and either the reissuance by Company of this Secured Note to the new holder or the issuance by Company of a new note to the new holder.
13.Excessive Interest. Notwithstanding any other provision herein to the contrary, this Secured Note is hereby expressly limited so that the interest rate charged hereunder shall at no time exceed the maximum rate permitted by applicable law. If, for any circumstance whatsoever, the interest rate charged exceeds the maximum rate permitted by applicable law, the interest rate shall be reduced to the maximum rate permitted, and if Holder shall have received an amount that would cause the interest rate charged to be in excess of the maximum rate permitted, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing hereunder (without charge for prepayment) and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal, such excess shall be refunded to the Company.
14.Waiver of Notice. The Company and all sureties, endorsers and guarantors hereby waive all notices required by law, including without limitation presentment and demand for payment, protest, and notice of demand, protest, dishonor and nonpayment. This Secured Note shall be the joint and several obligation of all makers, sureties, endorsers and guarantors, and shall be binding upon them and their successors and assigns. The non-exercise by Holder of their rights hereunder in any particular situation shall not constitute a waiver thereof in that or any subsequent instance.
15.Attorneys' Fees. If any litigation or other dispute resolution proceeding is commenced between parties to this Secured Note to enforce or determine the rights or responsibilities of the parties, the prevailing party or parties in the proceeding will be entitled to receive, in addition to any other relief granted, its reasonable attorneys' fees, expenses, and costs incurred preparing for and participating in the proceeding.
