ITEM 2.

IDENTITY AND BACKGROUND.

(a,b)      This Schedule 13D is being filed on behalf of (i) Cato Holding Company, a North Carolina corporation, with its principal office at 4364 South Alston Avenue, Durham, North Carolina 27713-2220 and (ii) Dr. Allen E. Cato (“Dr. Cato”), c/o Cato Holding Company, 4364 South Alston Avenue, Durham, North Carolina 27713-2220.

(d)        Neither Dr. Cato nor Cato Holding Company, individually or collectively, has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemanors).

(e)        Neither Dr. Cato nor Cato Holding Company, individually or collectively, has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is 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.

 

 

ITEM 3.

SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

           Cato Holding Company and Dr. Cato acquired their shares, warrants and options of the Issuer in connection with the May 11th, 2011 merger of a Vistagen Therapeutics, Inc., a California corporation (“Vistagen”), with Excaliber Merger Subsidiary, Inc., a subsidiary of the Issuer (the “Merger”). In the Merger, shares of Vistagen stock held by Cato Holding Company and Dr. Cato were converted into shares of the Issuer's Common Stock. Similarly, warrants and options which previously were exercisable for Vistagen Common Stock converted into warrants and options, respectively, exercisable for the Issuer's Common Stock.

           Cato Holding Company acquired its Vistagen shares and warrants in a number of transactions between August 30, 2001 and May 10, 2011. As consideration for these shares and warrants, Cato Holding Company paid, in aggregate, $400,000 in cash, performed services for Vistagen valued at $957,593, and agreed to perform services valued at $275,000 following the Merger. In addition, Cato Holding Company received 542,700 shares of Vistagen in connection with the April 28, 2003 merger between Vistagen and Artemis Neuroscience, Inc.

           The source of the funds used by Cato Holding Company to purchase the shares was working capital of Cato Holding Company. No part of the purchase price was borrowed by Cato Holding Company for the purpose of acquiring such securities.

           Dr. Cato received his shares for a total of $34,586 in cash. His warrant to purchase Vistagen shares was transferred to him from Cato Holding Company as partial compensation for services he rendered to Cato Holding Company. Additionally, Dr. Cato received an option to purchase Vistagen common stock as compensation in connection with his prior service on Vistagen's Board of Directors.

           The source of funds used by Dr. Cato to purchase his shares and warrant was personal funds. No part of the purchase price was borrowed by Dr. Cato for the purpose of acquiring such securities.

 

 

ITEM 4.

PURPOSE OF TRANSACTION.

           Cato Holding Company and Dr. Cato hold the securities described in Item 5 of this statement for investment purposes only. They have no plan or proposal which related to, or would result in, any of the actions enumerated in Item 4 of the instructions to Schedule 13D.



 

 

ITEM 5.

INTEREST IN SECURITIES OF THE ISSUER.

(a,b)      Regarding aggregate beneficial ownership and precentage beneficial ownership, see Rows 11 and 13, respectively, of the cover page relating to Cato Holding Company and Dr. Cato. Regarding sole and shared power to vote shares, see Rows 7 and 8, respectively, of the cover pages. Regarding the sole power and shared power to dispose of shares, see Rows 9 and 10, respectively, of the cover pages.

             Cato Holding Company beneficially holds 1,615,038 shares of the Issuer's Common Stock, corresponding to 14.8% of the Issuer's Common Stock, on a fully-diluted basis. Because Dr. Cato is the Chief Executive Officer and majority holder of Cato Holding Company, he is deemed to be the beneficial owner of these 1,615,038 shares of the Issuer's Common Stock held by Cato Holding Company under Rule 13d-3(a).

             Dr. Cato beneficially holds 1,648,301 shares of the Issuer‹s Common Stock, corresponding to 15.1% of the Issuer's Common Stock, on a fully-diluted basis. Such amount includes 1,615,038 shares benefically held by Cato Holding Company. Dr. Cato disclaims any beneficial interest except to the extent of his pecuniary interest in such shares.

(c)         Under an April 27, 2011 Securities Purchase Agreement, Cato Holding Company agreed to acquire 157,143 shares of Vistagen Common Stock in exchange for $275,000 of services to be provided by Cato Holding Company to Vistagen Common Stock.

             On April 29, 2011, the holders of Vistagen Preferred Stock converted their preferred shares in to shares of Vistagen Common Stock. As a result, 9,017 shares of Vistagen Series B Preferred Stock, 1,085,400 shares of Vistagen Series B-1 Preferred Stock and 35,423 shares of Vistagen Series C Preferred Stock, each held by Cato Holding Company, converted into a total of 1,129,840 shares of Vistagen Common Stock. Similarly, 5,339 shares of Vistagen Series C Preferred Stock then held by Dr. Cato converted into 5,339 shares of Vistagen Common Stock.

             On April 29, 2011, Vistagen entered into a Conversion Agreement with various holders of promissory notes previously issued by Vistagen. Cato Holding Company was one of those holders. Under this agreement and a related subscription agreement, Cato Holding Company converted $350,000 due under a note for 226,000 shares of Vistagen Common Stock and a warrant to purchase 56,500 shares of Vistagen Common Stock at $5.00 per share.

             On May 10, 2011, two convertible promissory notes, totaling $1,110,101, issued by Vistagen to Cato Holding Company automatically converted into 634,343 shares of Vistagen Common Stock and a warrant to purchase 158,585 shares of Vistagen Common Stock at $2.50 per share.

             On May 11, 2011, Vistagen merged with Excaliber Merger Subsidiary, Inc., a subsidiary of the Issuer. As a result of this merger, each share of Vistagen was converted into the right to receive half of a share of the Issuer. In addition, each warrant or option to purchase Vistagen Common Stock was converted into the right to receive a warrant or option to purchase half the number of shares Issuer's Common Stock as the original warrant or option would have been exercisable for, at twice the exercise price as the original warrant or option.

 

 

ITEM 6.

CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

          Dr. Cato is the Chief Executive Officer and majority stockholder of Cato Holding Company and, in such roles, has the power to direct the voting and sale of shares held by Cato Holding Company.
