CUSIP NO. 21924P103   Schedule 13D/A   Page 7 of 15
Schedule 13D/A
This Amendment No. 1 (this “Amendment”) amends and restates the Report on Schedule 13D, originally filed on May 12, 2008 (as amended, the “Schedule 13D/A”).
Item 1. Security and Issuer.
This statement on Schedule 13D/A relates to the common stock, par value $0.001 per share, of Cornerstone Therapeutics Inc., a Delaware corporation (the “Issuer”). The address of the Issuer’s principal executive offices is 2000 Regency Parkway, Suite 255, Cary, NC 27518.
Item 2. Identity and Background.
This Schedule 13D/A is being filed jointly pursuant to Rule 13d-1(k)(1) on behalf of Cornerstone BioPharma Holdings, Inc., a Delaware corporation (“CBPHI”), Cornerstone BioPharma Holdings, Ltd., an Anguilla company (“CBPHLtd”), Carolina Pharmaceuticals Ltd, a Bermuda company (“Carolina”), Carolina Pharmaceuticals Holdings, Ltd., a Bermuda company (“Carolina Holdings”), and Craig A. Collard, a citizen of the United States. CBPHI and Carolina are specialty pharmaceutical companies, and CBPHLtd and Carolina Holdings are holding companies. Carolina Holdings beneficially owns 100% of Carolina. Mr. Collard is (i) the President, Chief Executive Officer and Chairman of the Board of the Issuer, (ii) the President, Chief Executive Officer and a Director of CBPHI, (iii) the President, Chief Executive Officer, Director and beneficial owner of 100% of CBPHLtd, and (iv) the Chief Executive Officer, Chairman of the Board, and a Director of Carolina and Carolina Holdings. CBPHI, CBPHLtd, Carolina, Carolina Holdings, and Mr. Collard are collectively referred to herein as the “Reporting Persons”.
The business address of CBPHI, CBPHLtd, and Mr. Collard is c/o Cornerstone Therapeutics Inc., 2000 Regency Parkway, Suite 255 Cary, NC 27518. The business address of Carolina is Mitchell House, The Valley, Anguilla, British West Indies. The business address of Carolina Holdings is Canon’s Court, 22 Victoria Street, Hamilton HM 12, Bermuda.
The Reporting Persons have not, during the five years prior to the date of this Schedule 13D/A, (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, as a result of which the Reporting Persons were or are subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
Please see Schedule I for information pertaining to the executive officers and directors of CBPHI, CBPHLtd, Carolina and Carolina Holdings.
Item 3. Source and Amount of Funds or Other Consideration.
On May 1, 2008, the Issuer, then named Critical Therapeutics, Inc., Neptune Acquisition Corp., a wholly owned subsidiary of the Issuer (the “Transitory Subsidiary”), and CBPHI entered into an Agreement and Plan of Merger (the “Merger Agreement”), which was subsequently amended by Amendment No. 1 to the Merger Agreement on August 7, 2008. Under the Merger Agreement, the Transitory Subsidiary was to be merged with and into CBPHI (the “Merger”), with CBPHI continuing after the Merger as the surviving corporation and a wholly owned subsidiary of the Issuer. On October 31, 2008, Merger was consummated, and the Issuer was renamed Cornerstone Therapeutics Inc.
Concurrently with execution of the Merger Agreement, CBPHLtd and Mr. Collard each entered into agreements with the Issuer (the “Cornerstone Stockholder Agreements”) that provide, among other things, that they would vote in favor of adoption of the Merger Agreement and grant to the Issuer an irrevocable proxy to vote all of their shares of CBPHI common stock in favor of adoption of the Merger Agreement and against any proposal made in opposition to, or in competition with, the proposal to adopt the Merger Agreement. In addition, they agreed not to transfer or otherwise dispose of any shares of the Issuer’s common stock that they received in the Merger for 180 days after the effective time of the Merger.
Also concurrently with the execution of the Merger Agreement, funds managed by Healthcare Ventures and Advanced Technology Ventures, which owned in the aggregate approximately 19.2 percent of the Issuer’s then outstanding common stock, entered into agreements with CBPHI and the Issuer (the “Critical Stockholder Agreements”). The Critical Stockholder Agreements provided, among other things, that such stockholders would vote in favor of the issuance of the Issuer’s common stock in the Merger and granted to CBPHI a proxy to vote all of such stockholders’ shares in favor of the issuance of the Issuer’s common stock in the Merger. Prior to the effective time of the Merger, CBPHI, CBPHLtd and Mr. Collard were each deemed to beneficially own 8,335,455 shares of common stock of the Issuer subject to the Critical Stockholder Agreements. Because the Critical Stockholder Agreements terminated at the effective time of the Merger, the Reporting Persons are no longer deemed to beneficially own such shares.

 


 

CUSIP NO. 21924P103   Schedule 13D/A   Page 8 of 15
In April 2004, Cornerstone BioPharma, Inc. (“CBI”), a wholly owned subsidiary of CBPHI, entered into an unsecured loan agreement with Carolina (the “Carolina Note”), whereby CBI could borrow up to $15.0 million at 10% interest for five years. Contemporaneously with CBPHI’s execution of the Merger Agreement, the Issuer, CBPHI, CBI and Carolina entered into an agreement (the “Noteholder Agreement”) that provided, among other things, for the conversion or exchange of the outstanding principal amount of the Carolina Note into approximately 18% of the shares of CBPHI’s common stock outstanding immediately prior to the effective time of the Merger and for the same voting and lock-up provisions provided for pursuant to the Cornerstone Stockholder Agreements. On August 7, 2008, the parties to the Noteholder Agreement entered into Amendment No. 1 to the Noteholder Agreement, which amended the provisions of the Noteholder Agreement relating to the timing of the conversion and the number of shares to be issued in connection with the conversion of all or a portion of the outstanding principal and accrued interest under the Carolina Note into shares of common stock of CBPHI prior to the effective time of the Merger.
Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, all outstanding shares of CBPHI’s common stock were converted into and exchanged for shares of the Issuer’s common stock and all outstanding options, whether vested or unvested, and all outstanding warrants to purchase CBPHI’s common stock were assumed by the Issuer and became options and warrants to purchase the Issuer’s common stock. At the effective time of the Merger, the Reporting Persons’ shares of CBPHI stock were converted and exchanged for an aggregate of 4,646,138 shares of the Issuer’s common stock, and the Reporting Persons’ options and warrants to purchase CBPHI stock were assumed by the Issuer and became options and warrants to purchase an aggregate of 285,699 shares of the Issuer’s common stock, of which options to purchase 71,424 shares are exercisable within 60 days. The exchange ratio per share of CBPHI’s common stock was based on the number of shares of CBPHI’s common stock outstanding immediately prior to the effective time of the Merger on a fully diluted basis and was 0.2380837.
The descriptions of the Merger Agreement, Amendment No. 1 to the Merger Agreement, the Cornerstone Stockholder Agreements, the Critical Stockholder Agreements, the Noteholder Agreement, and Amendment No.1 to the Noteholder Agreement do not purport to be complete and are qualified in their entirety by the following, which are incorporated herein by reference: (i) the Merger Agreement, which is referenced herein as Exhibit 99.01, (ii) Amendment No. 1 to the Merger Agreement, which is referenced herein as Exhibit 99.02, (iii) the Cornerstone Stockholder Agreements, the form of which is Exhibit A-1 to the Merger Agreement, (iv) the Critical Stockholder Agreements, the form of which is Exhibit A-3 to the Merger Agreement, (v) the Noteholder Agreement, which is referenced herein as Exhibit 99.03, and (vi) Amendment No. 1 to the Noteholder Agreement, which is referenced herein as Exhibit 99.04.
Item 4. Purpose of Transaction.
The Reporting Persons acquired the shares of common stock of the Issuer for investment purposes. Subject to, among other things, the Issuer’s business prospects, prevailing prices, and market conditions, the Reporting Persons may dispose of or purchase additional shares of common stock and/or other securities of the Issuer from time to time in the open market, in privately negotiated transactions, or otherwise.
Except as may be set forth in this Schedule 13D/A, the Reporting Persons have no plans or proposals which would relate or result in any of the matters set forth below:
