Upon the face or back of each stock certificate issued to represent any such partly paid shares, upon the books and records of the Corporation in the case of uncertificated partly paid shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated.

Shares of the Corporation shall be transferable in the manner prescribed by law and in these Bylaws.

Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice or any waiver by electronic transmission unless so required by the Certificate of Incorporation or these Bylaws.

ARTICLE VIII - NOTICE BY ELECTRONIC TRANSMISSION

8.1 NOTICE BY ELECTRONIC TRANSMISSION.

Without limiting the manner by which notice otherwise may be given effectively to stockholders pursuant to the DGCL, the Certificate of Incorporation or these Bylaws, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these Bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice to the Corporation. Any such consent shall be deemed revoked if:

(i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices given by the Corporation in accordance with such consent; and

(ii) such inability becomes known to the secretary or an assistant secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice.

(2) However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

Any notice given pursuant to the preceding paragraph shall be deemed given:

An affidavit of the secretary or an assistant secretary or of the transfer agent or other agent of the Corporation that the notice has been given by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

8.2 DEFINITION OF ELECTRONIC TRANSMISSION.

(c) “ Foreign Stock Record ” shall have the meaning set forth in Section 10.3.

(d) “ Non-Citizen ” shall mean any person or entity who is not a “citizen of the United States” (as defined in Section 41102 of the Act and administrative interpretations issued by the Department of Transportation, its predecessors and successors, from time to time), including any agent, trustee or representative of a Non-Citizen.

(e) “ Own or Control ” or “ Owned or Controlled ” shall mean (x) ownership of record, (y) beneficial ownership or (z) the power to direct, by agreement, agency or in any other manner, the voting of Stock. Any determination by the Board of Directors as to whether Stock is Owned or Controlled by a Non-Citizen shall be final.

(f) “ Permitted Percentage ” shall mean 25% of the voting power of the Stock.

(g) “ Stock ” shall mean the outstanding capital stock of the Corporation entitled to vote; provided , however , that for the purpose of determining the voting power of Stock that shall at any time constitute the Permitted Percentage, the voting power of Stock outstanding shall not be adjusted downward solely because shares of Stock may not be entitled to vote by reason of any provision of this Article X.

10.2 LIMITATIONS ON OWNERSHIP

It is the policy of the Corporation that, consistent with the requirements of the Act, Non-Citizens shall not Own and/or Control more than the Permitted Percentage and, if Non-Citizens nonetheless at any time Own and/or Control more than the Permitted Percentage, the voting rights of the Stock in excess of the Permitted Percentage shall be automatically suspended in accordance with Sections 10.3 and 10.4.

confirming that the closing occurred. Failure to send such confirmatory notice shall result in the removal of such Stock from the Foreign Stock Record.

In the event that the sale pursuant to such definitive agreement is not consummated in accordance with such agreement (as may be amended), such Stock shall be removed from the Foreign Stock Record without further action by the Corporation. The Foreign Stock Record shall include (i) the name and nationality of each such Non-Citizen and (ii) the date of registration of such shares in the Foreign Stock Record.
