Related Party Transactions	14. Related Party Transactions Cato Holding Company (CHC), doing business as Cato BioVentures (CBV), the parent of CRL, is one of our largest institutional stockholders at March 31, 2016, holding common stock and Series B Preferred. Shawn Singh, our Chief Executive Officer and member of our Board of Directors, served as Managing Principal of CBV and as an officer of CRL until August 2009. On October 10, 2012, we issued to CHC an unsecured promissory note in the principal amount of $310,400 (the 2012 CHC Note) and a five-year warrant to purchase 12,500 restricted shares of our common stock at a price of $30.00 per share (the CHC Warrant). Additionally, on October 10, 2012, we issued to CRL: (i) an unsecured promissory note in the initial principal amount of $1,009,000, which is payable solely in restricted shares of our common stock and which accrues interest at the rate of 7.5% per annum, compounded monthly (the CRL Note), as payment in full for all contract research and development services and regulatory advice rendered to us by CRL through December 31, 2012 with respect to the preclinical and clinical development of AV-101, and (ii) a five-year warrant to purchase, at a price of $20.00 per share, 50,450 restricted shares of our common stock, such number of shares to be adjusted in relation to accrued interest on the CRL Note (CRL Warrant). As disclosed in Note 8, Convertible Promissory Notes and Other Notes Payable, the Cato Notes and additional amounts payable to CRL for CRO services were extinguished in June 2015 in exchange for our issuance of an aggregate of 328,571 shares of Series B Preferred to CHC. CHC also participated in the February 2016 warrant exchange disclosed in Note 9, Capital Stock, exchanging the CHC Warrant and the CRL Warrant, as adjusted to reflect accrued interest, for an aggregate of 54,894 shares of our unregistered common stock. Under the terms of VistaGen California’s contract research organization arrangement with CRL related to the development of AV-101, we incurred expenses of $52,600 and $38,100 for the fiscal years ended March 31, 2016 and 2015, respectively. Total interest expense on notes payable to CHC and CRL was $28,200 and $175,900 for the fiscal years ended March 31, 2016 and 2015, respectively. Upon the approval of its Board of Directors, in December 2006, VistaGen California accepted a full-recourse promissory note in the amount of $103,400 from Mr. Shawn Singh in payment of the exercise price for options and warrants to purchase an aggregate of 6,320 restricted shares of VistaGen California’s common stock. The note accrued interest at a rate of 4.90% per annum and was due and payable no later than the earlier of (i) December 1, 2016 or (ii) ten days prior to VistaGen California becoming subject to the requirements of the Securities Exchange Act of 1934, as amended (Exchange Act). On May 11, 2011, in connection with the Merger, the $128,200 outstanding balance of principal and accrued interest on this note was cancelled in accordance with Mr. Singh's employment agreement and recorded as additional compensation. In accordance with his employment agreement, Mr. Singh was also entitled to receive an income tax gross-up on the compensation related to the note cancellation. At March 31, 2015, we had accrued $101,900 as an estimate of the gross-up amount, which amount was paid to Mr. Singh during fiscal 2016. Between September and December 2013, Mr. Singh provided short-term cash advances aggregating $64,000 to meet our short-term working capital requirements. In lieu of cash repayment of the advances, in December 2013, Mr. Singh elected to invest $50,000 of the balance due him in our private placement financing. At March 31, 2015, we had completely repaid to Mr. Singh the balance of the advances and the $50,000 promissory note issued in connection with his investment in the private placement.
