If at any time during the Eligible Period the Stockholder requests in writing (the “Stockholder Demand”) that the Company file a registration statement on Form S-1 (or any successor form to Form S-1) for a public offering of shares of the Registrable Shares of all the Stockholders of the Company and shall, subject to Section 4.1, file such Registration Statement with the SEC as soon as practical after its receipt of such request. The Company shall use commercially reasonable efforts to cause such Registration Statement to be declared effective as soon thereafter as practicable and keep such Registration Statement effective until all the Stockholders, excluding any officers or directors, notify the Company in writing that the Company is no longer required to keep such Registration Statement effective.

At any time after the date which is six (6) months after the closing of the Company’s first firm commitment underwritten public offering of shares of Common Stock pursuant to a Registration Statement, a Stockholder or Stockholders holding at least 25% of the Registrable Shares may request, in writing, that the Company effect the registration on Form S-1 (or any successor form) of Registrable Shares owned by such Stockholders having an aggregate offering price of at least $10,000,000 (based on the market price or fair value at the time of such request). If the Stockholders initiating the registration intend to distribute the Registrable Shares by means of an underwriting, they shall so advise the Company in their request. Upon receipt of any such request, the Company shall promptly give written notice of such proposed registration to all Stockholders. Such Stockholders shall have the right, by giving written notice to the Company within ten (10) business days after the Company provides its notice, to elect to have included in such registration such of their Registrable Shares as such Stockholders may request in such notice of election; provided, however, if the underwriter (if any) managing the offering determines that, because of marketing factors, not all of the Registrable Shares requested to be registered by all of the Stockholders may be included in the offering, then all Stockholders who have requested registration shall participate in the registration pro rata based upon the number of Registrable Shares which they have requested to be so registered. Thereupon, the Company shall, as expeditiously as possible, use its reasonable best efforts to effect the registration on Form S-1 (or any successor form) of all Registrable Shares which the Company has been requested to so register.
