Demand Registration Rights

The holders of registrable securities are entitled to demand registration rights. Beginning 180 days after the completion of the Offering, the Issuer will be required, upon the written request of a majority of holders of the registerable securities then outstanding that would result in an aggregate offering price of at least $10 million, to file a registration statement on Form S-1 with respect to at least 40% of the registrable securities then outstanding and to use commercially reasonable efforts to effect the registration of all or a portion of these shares for public resale.

Short Form Registration Rights

The holders of registrable securities are also entitled to short form registration rights. Pursuant to the Investors’ Rights Agreement, if the Issuer is eligible to file a registration statement on Form S-3, upon the written request of at least 20% in interest of these holders to sell registrable securities at an aggregate price of at least $5 million, the Issuer will be required to use commercially reasonable efforts to effect a registration of such shares. The Issuer is required to effect only one registration in any twelve month period pursuant to this provision of the Investors’ Rights Agreement.

Piggyback Registration Rights

The holders of registrable securities are entitled to piggyback registration rights. If the Issuer registers any of our securities either for its own account or for the account of other security holders, the holders of registrable securities will be entitled to include their shares in the registration. Subject to certain exceptions contained in the Investors’ Rights Agreement, the Issuer and the underwriters may limit the number of shares included in an underwritten offering to the number of shares which the Issuer and the underwriters determine in their sole discretion will not jeopardize the success of the offering.

Indemnification

The Investors’ Rights Agreement contains customary cross-indemnification provisions, under which the Issuer is obligated to indemnify holders of registrable securities in the event of material misstatements or omissions in the registration statement attributable to the Issuer, and the selling stockholders are obligated to indemnify the Issuer for material misstatements or omissions attributable to them.

Expiration of Registration Rights

The registration rights granted under the Investors’ Rights Agreement will terminate on the earliest to occur of (i) the closing of a deemed liquidation event, as defined in the Issuer’s Restated Certificate of Incorporation, (ii) such time as the registrable securities held by the Reporting Persons may be sold within any three-month period without restriction pursuant to Rule 144 or a similar exemption under the Securities Act or (iii) the third anniversary of the Offering.

The foregoing description of the Investors’ Rights Agreement is intended as a summary only and is qualified in its entirety by reference to the Investors’ Rights Agreement, which is filed as an exhibit to this Schedule 13D and incorporated herein.
