Item 1.01. Entry into a Material Definitive Agreement.
On May 1, 2008, Critical Therapeutics, Inc. (the “Company”), Neptune Acquisition Corp., a wholly owned subsidiary of the Company (the “Transitory Subsidiary”), and Cornerstone BioPharma Holdings, Inc. (“Cornerstone”) entered into an Agreement and Plan of Merger (the “Merger Agreement”). Under the Merger Agreement, the Transitory Subsidiary will be merged with and into Cornerstone (the “Merger”), with Cornerstone continuing after the Merger as the surviving corporation and a wholly owned subsidiary of the Company.
At the effective time of the Merger, all outstanding shares of Cornerstone’s common stock will be converted into and exchanged for shares of the Company’s common stock and all outstanding options, whether vested or unvested, and all outstanding warrants to purchase Cornerstone’s common stock will be assumed by the Company and become options and warrants to purchase the Company’s common stock. The Merger Agreement provides for the Company to issue in the Merger to Cornerstone stockholders, and assume Cornerstone options and warrants that will represent, an aggregate of approximately 101.5 million shares of the Company’s common stock, subject to adjustment as a result of a reverse stock split of the Company’s common stock to occur in connection with the Merger. Immediately following the effective time of the Merger, Cornerstone’s stockholders will own approximately 70 percent, and the Company’s current stockholders will own approximately 30 percent, of the Company’s common stock, after giving effect to shares issuable pursuant to Cornerstone’s outstanding options and warrants, but without giving effect to any shares issuable pursuant to the Company’s outstanding options and warrants. The exchange ratio per share of Cornerstone’s common stock will be based on the number of shares of Cornerstone’s common stock outstanding immediately prior to the effective time of the Merger and will not be calculated until that time.
Following consummation of the Merger, the Company will be renamed Cornerstone Therapeutics Inc. and its headquarters will be located in Cary, North Carolina, at Cornerstone’s headquarters. Promptly after the effective time of the Merger, the Company has agreed to appoint directors designated by Cornerstone to the Company’s Board of Directors, specified current directors of the Company will resign from the Board of Directors and the Company will appoint new executive officers designated by Cornerstone.
Immediately prior to the effective time of the Merger, the Company has agreed to effect a reverse stock split of its common stock whereby each issued and outstanding share of its common stock will be reclassified and combined into a fractional number of shares of common stock. The reverse stock split ratio is to be mutually agreed upon by the Company and Cornerstone. The reverse stock split is necessary so that as of the effective time of the Merger the Company will satisfy the minimum bid price requirement pursuant to NASDAQ’s initial listing standards.
Consummation of the Merger is subject to a number of closing conditions, including adoption of the Merger Agreement by Cornerstone’s stockholders, approval by the Company’s stockholders of the issuance of the Company’s common stock in the Merger, the reverse stock split and the change in the Company’s name, expiration or termination of any waiting period under the Hart-Scott-Rodino Antitrust Improvements Action of 1976, approval by NASDAQ of the Company’s application for re-listing of the Company’s common stock in connection with the Merger, the continued availability of the Company’s products and other customary closing conditions as set forth in the Merger Agreement.
The Merger Agreement contains customary representations, warranties and covenants, including covenants relating to obtaining the requisite approvals of the stockholders of the Company and Cornerstone, solicitation of competing acquisition proposals by the Company and Cornerstone, listing of

the Company’s common stock on NASDAQ and the Company’s and Cornerstone’s conduct of its business between the date of signing the Merger Agreement and the closing of the Merger.
The Merger Agreement provides for the payment of a termination fee of $1.0 million by each of the Company and Cornerstone to the other party in specified circumstances in connection with the termination of the Merger Agreement. In addition, in specified circumstances in connection with termination of the Merger Agreement, the Company has agreed to reimburse Cornerstone for up to $150,000 in expenses and Cornerstone has agreed to reimburse the Company for up to $100,000 in expenses.
The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.
The Merger Agreement contains representations and warranties of the Company, the Transitory Subsidiary and Cornerstone made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract among the Company, the Transitory Subsidiary and Cornerstone and may be subject to important qualifications and limitations agreed to by the Company, the Transitory Subsidiary and Cornerstone in connection with the negotiated terms. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to stockholders or may have been used for purposes of allocating risk among the Company, the Transitory Subsidiary and Cornerstone rather than establishing matters as facts.
Concurrently with the execution of the Merger Agreement, funds managed by Healthcare Ventures and Advanced Technology Ventures, which own in the aggregate approximately 19 percent of the Company’s outstanding common stock, have entered into agreements that provide, among other things, that the stockholders will vote in favor of the issuance of the Company’s common stock in the Merger and grant to Cornerstone a proxy to vote all of such stockholders’ shares in favor of the issuance of the Company’s common stock in the Merger. Likewise, holders of a majority of the shares of Cornerstone’s outstanding common stock have entered into agreements that provide, among other things, that the stockholders will vote in favor of adoption of the Merger Agreement and grant to the Company a proxy to vote all of such stockholders’ shares in favor of adoption of the Merger Agreement. In addition, these Cornerstone stockholders have agreed not to transfer or otherwise dispose of any shares of the Company’s common stock that they receive in the Merger for 180 days after the effective time of the Merger. Furthermore, Carolina Pharmaceuticals Ltd., which is the holder of a promissory note issued to a wholly owned subsidiary of Cornerstone, has entered into an agreement that provides, among other things, for the conversion of the principal amount of such note into shares of Cornerstone’s common stock prior to the effective time of the Merger and for the same voting and lock-up provisions provided for pursuant to the agreements that Cornerstone’s other stockholders have entered into.
Important Additional Information Will Be Filed with the SEC
The Company plans to file with the U.S. Securities and Exchange Commission (“SEC”) a Registration Statement on Form S-4 and file with the SEC and mail to its stockholders a Proxy Statement/Prospectus in connection with the transaction. The Registration Statement and the Proxy Statement/Prospectus will contain important information about the Company, Cornerstone, the transaction and related matters. Investors and security holders are urged to read the Registration Statement and the Proxy Statement/Prospectus carefully when they are available.

As of April 30, 2008, the Company’s directors and executive officers beneficially owned approximately 10,334,319 shares, or 22.9 percent, of the Company’s common stock.
