Concurrent Placement
Société des Produits Nestlé S.A, or Nestlé, an affiliate of one of our existing stockholders, has agreed to
purchase $20.0 million of shares of our common stock in a concurrent registered placement, at a sale price per share equal to 97% of the public offering price of our common stock in the offering of common stock to which the preliminary
prospectus relates, or the offering. We refer to this transaction herein as the concurrent placement. The consummation of the concurrent placement is contingent upon the closing of the offering, and the satisfaction of certain other customary
conditions. However, the consummation of the offering is not contingent on the consummation of the concurrent placement. The concurrent placement may have two closings, the first of which may occur on or within two business days of the closing of
the offering for a number of shares equal to the maximum number (not to exceed $16.0 million of shares) of shares that Nestlé may purchase without clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or
the HSR Act, which we refer to herein as the HSR clearance. A second closing for the remaining shares will occur following, and subject to, HSR clearance. Contingent on the requirement for HSR clearance, all $20.0 million of shares may be sold in
one of these closings.
Risks Related to the Concurrent Placement
The offering is not contingent on the consummation of the concurrent placement, which may not close or may close for only those number of
shares that do not require HSR clearance.
The consummation of the offering is not contingent on the consummation of the
concurrent placement, which may not close or may close for only those number of shares that do not require HSR clearance. A second closing will be held for any shares that require HSR clearance, which may be all of the shares. Before a second
closing of the concurrent placement can occur, we and Nestlé will have to make certain filings under the HSR Act and the applicable waiting period under the HSR Act will have to expire or be terminated. Governmental authorities may impose
conditions or request changes related to the filings and such conditions or changes, or the process of obtaining regulatory clearance, could have the effect of delaying consummation of the second closing of the concurrent placement or could result
in additional costs or limitations related to the concurrent placement. Regulatory clearance may not be received at all, may not be received in a timely fashion, and may contain conditions on the concurrent placement that are not anticipated or
cannot be met.
